Combine harvester "Akros". Combine harvester "Akros": technical characteristics, description, diagram and reviews

The Akros 530 (RSM-142) grain harvester is a fifth-class professional agricultural machinery developed by the Rostselmash organization. The model is versatile and allows you to perform a wide range of work. In the class of high-performance equipment, the Acros 530 is the most advantageous offer. The equipment belongs to a new generation of products aimed at large farms with huge areas of various crops.

Quite a long time has passed since the debut of the model. Prototypes appeared in 2006, and the official premiere of the combine took place on May 16, 2007. This was a landmark event for the Russian agricultural market, since machines of this level did not exist at that time. Akros 530 fully lived up to the expectations placed on it. Even with the emergence of serious competitors, the product remained among the leaders in terms of quality and cost.

Manufacturer

Currently, Rosselmash is included in the top five world leaders in the production of agricultural machinery. Products of this brand are produced at 13 enterprises built not only in Russia, but also in Kazakhstan, the USA, Ukraine, and Canada. Rosselmash equipment is sold in 26 countries around the world. And at the same time it is simply extremely popular. In addition to combines, the range includes 23 more types of equipment.

Design, characteristics

The layout was copied from foreign analogues. A cabin was installed in front along the axis of the machine, behind it was a storage hopper, and then the engine. This arrangement improves visibility and reduces the impact of vibration and noise on the operator. In addition, there is virtually no shift in the center of gravity when filling the bunker, which does not affect handling.

To produce combine harvesters, Rostselmash modernized production. 11 assembly sites were organized, more than 60 pieces of equipment were purchased for the amount of 800 million rubles.

Table No. 1. Technical characteristics

Available models

"Akros" is a combine harvester designed primarily for harvesting very large areas of high-yielding crops at high speed and without wasting time. During the season, using models of this brand, you can harvest more than 1000 hectares of grain and row crops (corn and sunflower).

Today it offers agricultural enterprises only four lines of this equipment. This is the Akros combine 530, 560, 580 and 590. All these models are characterized by high productivity and are adapted for harvesting a wide variety of crops. The differences between them lie primarily in engine power and speed of field work.

Thus, the Akros 580 combine harvester is equipped with a 300-horsepower 8.9-liter Cummins engine with minimal fuel consumption. In addition, the 580 model is equipped with a chopping drum that operates at two speeds. Threshing of grains in it is carried out in a mode of 3400 rpm, and a mode of 2000 rpm. designed for processing sunflower and corn.

The latest model of Rosselmash, the Akros 590, has increased power and can be used by the largest farms to process very large fields at high speed. Even in conditions of strong humidity, this combine is capable of producing 8 thousand tons per season.

Design

"Akros" 530 is positioned by the manufacturer as high-performance equipment. This combine is designed to work over large areas, with high and medium yields of grain crops. According to farmers, in one season the equipment is capable of harvesting about 1,200 hectares. Let's look at the key features of the combine.

Drum and cleaning system

The ACROS design includes one threshing drum, complemented by a five-key, seven-stage straw walker. This scheme of threshing and separating device allows you to separate up to 95% of the grain. The residual mass is sent to a two-stage fine cleaning system. This allows you to minimize grain loss and operate with a fairly high efficiency. Please note that it is superior even to combines with a double-drum cleaning system. The equipment is capable of working almost non-stop. This opportunity is provided by the JAN CONTROL device. This is a deep deck dump system that solves clogging problems when harvesting difficult crops.

Bunker and unloading

Separately, it is worth mentioning the SMART LAUNCH unloading system. This innovative solution helps to completely empty a 9,000 liter bin in less than 2 minutes. The high-speed unloading scheme eliminates clogging of the augers. First, the unloading devices are turned on, then the feed auger at the bottom of the hopper.

Cabin

Unlike its predecessors, Akros has a central cabin location. Coupled with panoramic glazing, this provides an all-round view, allowing you to control the cleaning process. In addition, the cabin has an increased level of comfort: there is a heating and air conditioning system. The self-diagnosis system looks interesting. A message about any malfunctions of working units is displayed on the information display of the on-board computer. It is worth noting that the main components are easily accessible, which makes it possible to carry out minor repairs in the field. This allows you to minimize equipment downtime during harvesting operations.

The main advantages of Akros combines

The main advantages of equipment produced by Rosselmash in comparison with models of other brands include:

1. Equipped with beater analyzers with retractable fingers and combs. This unit is located at the entrance of the feeder chamber and while the combine is operating, it actively levels the cut mass, which promotes its rapid progress even in conditions of severe contamination.
2. Equipped with modern Power Stream headers with a grip of 6.7 and 9 meters. Their use makes it possible to minimize grain losses due to shedding and ensure uniform feeding under all conditions.
3. The presence of a traditional, reliable drum thresher with high throughput, which is gentle on grain and straw.
4. Equipped with an autonomous final grinding device of a blade design. Thanks to its use, the risk of grain crushing is significantly reduced.
5. Equipped with reliable 6-cylinder engines, selected for both torque and power.
6. Availability of various types of adapters and additional devices. This makes it possible to perform a wide variety of work on the combine. And not only during the harvesting campaign, but throughout the entire season.

The advantages of this equipment, among other things, include being equipped with very wide Power Stream headers, adapted for working even on uneven fields. These machines cut crops very cleanly. At the moment, Akros grain harvesters occupy a leading position in Russia and are the most advanced equipment in this specialization.

Design and service features

The Akros 530 combine harvester received a standard layout (cabin, bunker, engine). A similar scheme has proven itself well on other machines of the brand. The cabin was located directly in the center, thanks to which the noise level was reduced and the area for servicing the engine was expanded.

A hydrostatic transmission was chosen for the combine, which has a number of advantages over a mechanical transmission. Minimal friction reduces wear, allowing for less maintenance time. The operator could adjust the speed in a stepless manner, and the transmission efficiency was maximized. The distribution of the kinematic transmission was carried out evenly, with no more than 2 consumers per shaft.

The hydraulic system included several hydraulic pumps, which supplied power to the attachments, steering and hydrostatic transmission. In this case, the elements had a common tank with oil. Dividing the system into separate circuits ensured uninterrupted operation of the units regardless of the load.

The steering operated hydraulically. For a large combine, this arrangement was especially convenient, since it reduced the operator's workload and ensured optimal control accuracy.

The combine's attachments have a number of specific features. Along with the start of production of the Acros 530 family, Rostselmash began production of advanced headers called Power Stream. Compared to previous Russian models, they were distinguished by high strength and low weight. The header was attached with hinges frontally to the inclined chamber and was equipped with a balancing mechanism, an automatic terrain control system in several directions (transverse and longitudinal), a 5-blade reel and an auger. The reel with a special trajectory of movement and the long tines of the rake confidently processed lodged and twisted bread. Previous models of headers had less efficiency in working with them. Thanks to the large diameter of the auger, winding of high-stem grains was practically eliminated. The need for additional fingers due to the deep turns of the auger has disappeared. The height of the cut of raw materials by the header was adjusted. At the same time, the reaping part completely copied the transverse and longitudinal area of ​​the field, using the working surface as efficiently as possible.

The operation of the reel was controlled by a hydraulic drive. For faster cleaning of the header, reverse was used. The control of the reaping part (speed adjustment, moving up and down, moving the reel in horizontal and vertical zones) was carried out using electro-hydraulic equipment. Another advantage of the new element is the ability to control it from the cockpit. Optionally, the combines were equipped with the Level Glide system, which reduces grain losses.

The following unique systems were also used in the design of the Akros 530 model:

• Adviser – on-board information system with voice notification;
• Smart Launch – a bunker unloading function that reduces the risk of clogging and increases unloading speed;
• JamControl is a mechanism for deep dumping of the drum deck, eliminating clogging with grain mass.

The Akros 530 cabin significantly surpassed all domestic analogues in terms of comfort. Working conditions on Russian combines have never been so modern.

The equipment salon is double (for the helmsman and the combine operator). The cabin is well protected from dust, vibration, noise and is completely sealed. It is installed on a sprung base (4 shock absorbers). In the basic configuration, the cabin is equipped with a refrigerator, a radio with an acoustic system and climate control. The cabin also has an on-board computer with the Adviser system. The equipment control buttons are located at arm's length from the workplace, and the steering column is adjustable in tilt and height. Panoramic glazing with a large area provides good visibility in different directions. The cab also has external halogen lighting, allowing work to be done at night.

Advantages of the Akros 530 model:

1. high economic efficiency. The combine is considered the most economical in its class, and in terms of productivity it is not inferior to its analogues;
2. high-quality work not only with grains, but also with sunflowers;
3. increased work comfort.

Disadvantages of the Akros 530 model:

1. low quality bearings. Stock bearings fall apart after 1-2 years of operation. Experts recommend replacing them with foreign analogues;
2. poor drive belts, the service life of which is limited to 2 years.

Features of operation

The advantages of Akros combines, in addition to excellent technical equipment, include ease of use. The cabins of all models are well protected from noise and vibration. Their central location provides a 360 degree view. The ergonomics of Akros combines have also been carefully worked out. All controls have a traditional location and are in direct visibility, which, of course, greatly facilitates the task of the combine operator. To work with this equipment, specialists do not need to undergo any additional training. Since models of this brand are manufactured by a domestic manufacturer, it is not difficult to find any parts and components if they need to be repaired. The diagram of the Akros 590 combine is presented below.

terms of Use

You can carry out agricultural work using combines produced by Rosselmash in any weather and regardless of the conditions. All models of this brand are equipped with thick tires with deep herringbone treads, designed for off-road driving.

"Akros" is a combine harvester that can be used even at temperatures up to +50 °C. This becomes possible thanks to the presence of a “smart” engine cooling system. When the temperature rises seriously, it turns on additional fans.

You can carry out agricultural work using equipment of this brand not only during the day, but also in the evening or even at night. Especially for this purpose, all combines are equipped with powerful LED spotlights.

Thanks to the original drum design, Akros combines can effectively and losslessly harvest grain that is in an almost horizontal position. All equipment systems from this manufacturer can be configured directly on the field.

Reviews about Akros

Domestic farmers have a simply wonderful opinion about these combines. Not only their advantages listed above are noted. These combines are also praised for the presence in their design of a unique rotor with a reverse deck, which has no analogues in the world. Thanks to the presence of this part, the risk of clogging on difficult and moist breads is completely eliminated. The excellent metal used for manufacturing is very resistant to corrosion - another characteristic of the Akros combine, which has earned it good reviews.

Of course, consumers also have a good opinion about this technology because of its low cost. For the same price as one imported combine, you can buy two Akros. At the same time, in terms of productivity, quality of grain harvesting and ease of maintenance, this equipment is practically in no way inferior to foreign ones.

The work of the specialists itself, as well as its dealers, is also noted in a positive way. In case of any breakdowns, the technicians promptly go to the site and quickly eliminate all faults.

Generator Set Cleaning Guidelines

If the gap is in the specified range and the magnet moves from the off position sensor to the automated on position sensor, but as a result a fault appears on the digital display, then one or both position sensors probably did not work in the control unit operating mode. If an open circuit is indicated, it is necessary to disconnect the PU block with this wire from the combine harness and use a multimeter to measure the resistance between the contact of this channel in the combine harness block and the combine body.

Features of the new ACROS 590 combines

This is the latest and most advanced model developed by the designers. The new Akros 590 Plus combine harvester differs from other lines in that its design includes:

• accelerating beater in the chamber;
• shredder with a new technological chamber;
• 325 horsepower engine.

"Akros" is a combine harvester, the design of which includes hydraulic copying and two-stage cleaning systems. The processing of corn and sunflower using a combine of this brand is carried out with very high quality, as it is equipped with a special chaff spreader. The feeder chamber of combine harvesters of this brand is increased in volume by 250 mm, which, of course, significantly increases their productivity.

Working bodies, operational parameters

Control module acros 530 At its core, a self-propelled harvester is a combination on one chassis of several mechanisms designed for harvesting and primary processing.

So the RSM 142 was equipped with a reaping part, a threshing unit, transport lines, and a bunker.

Harvest part

The harvester is equipped with a header of its own design. Rostselmash gave the advanced design the name Power Stream. If we compare the header with other similar mechanisms, it has increased strength with low weight. A special feature of the implement is the ability to lift even heavily fallen spikelets, which ensures efficient grain harvesting.

The company produces headers with working widths of 5, 6, 7, 9 m. The position of the implement relative to the machine is controlled by an electro-hydraulic drive. It is possible to operate the mechanism in two modes: copying the relief and at a fixed distance from the surface of the earth.

• In the first case, you can stepwise set the cutting height within 60, 100, 140, 180 mm.
• In a fixed position, the header is held by hydraulic cylinders at a distance of 180 to 900 mm from the ground surface.

The mechanism harvests at a speed of 3.3 hectares per hour.

The header is equipped with a self-cleaning function. The process occurs without operator intervention when reverse is activated.

Threshing unit

The mechanism is designed to separate grains from the plant mass. The design of the unit includes:

• threshing drum;
• breaker beater;
• straw walker;
• blowing chamber;
• storage bunker.

Combine harvester "Akros": technical characteristics

The Akros combines, as already mentioned, differ slightly in the degree and types of equipment. By reading the table below, you can find out what specific characteristics distinguish the 530, 580 and 590 models, as well as what similarities and differences exist between them.

Engine

The first modifications of the Acros 530 were equipped with a 4-stroke V-shaped diesel engine with turbocharging and liquid cooling, model YaMZ 236BK (manufacturer: Yaroslavl Motor Plant). These motors were also installed on Yenisei 860 combines (Krasnoyarsk Combine Plant). The unit had compression ignition, intercooling of charge air and direct fuel injection. The engine was adapted to Russian operating conditions and withstood significant loads.

Characteristics of the YaMZ 236BK motor:

• working volume – 11.15 l;
• rated power – 184 (250) kW (hp);
• rated speed – 2000 rpm;
• maximum torque – 1030 Nm;
• fuel consumption -159 g/hp. at one o'clock;
• Fuel tank capacity – 540 l.

Later versions of the combine were equipped with a foreign 4-stroke Gummins diesel unit with turbocharged fuel supply and in-line cylinder arrangement. The engine was highly efficient and could operate for up to 16 hours without refueling. The cooling system of the unit automatically turned on additional fans when the temperature approached a critical level, which extended the life of the power plant.

Gummins motor characteristics:

• working volume – 8.3 l;
• rated power - 280-300 hp.

Cost of combines

The price of an Akros combine harvester depends primarily on the model. Also, the cost of this equipment may vary depending on the general condition and its equipment. On average, it ranges from 3-5 million rubles. Harvesters from this manufacturer are sold through official dealers. Representatives sell on the market not only the equipment itself, but also various kinds of additional units intended for installation on it. This could be, for example, intense lighting, enlarged threshing blades, drums of unequal dimensions, different types of tires, conveyor belts, etc.

Application area

The Akros grain harvester is in demand in agriculture; it is used for separate harvesting of wheat (winter or spring), rye, barley and other cereal crops.

Thanks to the two-level header hitch provided by the designers, Akros can harvest sunflower and corn.

The combine can be used on any type of soil; it confidently moves off-road, which makes its delivery to the work site less expensive. The improved design of the cabin and header allows harvesting in any weather. Productive grips are capable of picking up stems pressed to the ground.

Used models

You can also buy used combines of this brand on the secondary market. The cost of such equipment, of course, will be less. The price for used models ranges from 2-3 million rubles, depending on the model.

As you can see, the Akros combine is actually very reliable, high-quality and has rightfully earned good reviews from consumers. The equipment is inexpensive, but various types of agricultural work can be carried out with its use conveniently, quickly and without losses.

Features of the versions

Users immediately liked the car, even despite the fact that the RSM 142 is presented in only one modification. It is possible to attach headers with different working widths.

Separate installation of mechanisms for collecting corn and sunflower is provided. The popularity of the model can be explained by several features:

• low price - in the domestic market the device costs much less than its competitors;
• productivity - the combine shows consistently good results in harvesting grains or sunflowers;
• efficiency - the model’s engine consumes less fuel than other previously produced cars.
