Characteristics and purpose of trailed grain harvester models

A trailed grain harvester is a type of modern special equipment that is used to harvest grain crops. The grains are kept in perfect condition, and the grain stalks are processed. After cleaning the grain, it is shipped using a special hose. The stems remaining after processing serve as fertilizer, so machine operators throw them onto the ground, ensuring the circulation process.

Description of trailed grain harvester

The first combine was developed by Russian technologist A.R. Vlasenko. Initially, such machines could not move independently; they moved with the help of a tractor, however, later it was possible to achieve the independence of combine harvesters.

Modern special equipment not only collects grain crops, but does it carefully, which helps keep the grains in perfect condition.

Modern grain harvesters meet all conditions of comfort and safety. For example, the cabin is equipped with air conditioning, which makes it easy to withstand the heat, and special sensors are built inside the combine, which are responsible for ensuring that the machine does not roll over even on the steepest slope. All assembly units are also regulated by the system. They ensure that the entire machine operates accurately and smoothly.

The harvester carefully cuts the wheat stalks, then the grain is selected, the stalks are processed and thrown back onto the ground to later serve as fertilizer. This results in the so-called circulation. The cleaned grain is unloaded using a special hose and then sent to a flour mill or warehouse.

Prices for mini-harvesters and other technical data are indicated in the article.

Harvesters vary by crop. That is, different machines equipped with special functions are used to harvest different crops. There are combines for harvesting wheat, corn, oats and even rice. All these crops have their own characteristics when grown and, of course, they also need to be harvested in different ways.

Grain harvester KOP-3 "Rosich"

The trailed grain harvester KOP-3 "Rosich" is in demand in the modern agricultural market among other types of equipment used for the purpose of collecting and shipping grain and legumes from fields. Its operation is based on separate and direct combining. The machine package includes:

1. Replacement adapters for harvesting crops for grain.
2. Harvester for stripping crops with a rotary-type threshing and separating device.

Direct combining technology involves stripping the standing crop using a stripping device. Rotary-type threshing and separating equipment allows for threshing, including separation. KOP-3 “Rosich” grain harvesting equipment costs about 7 million rubles. This type of grain harvester is used by farms that have small acreage.

The cleaning technology is implemented according to the following scheme:

1. The movement of the unit causes the deflector to work, bending the stems to such an extent that all the ears are at the same level in height, leveling the layering of grain crops depending on their lodging.
2. The rotor, which has stripping combs, rotates, creating an air flow at high speed, then the air masses are sucked through the grain under the deflector device.
3. Due to the suction flow and their own elasticity, the stems are pressed against the rotating rotor after leaving the deflector.

The rotor has combs, which, as a result of the impact when stripping the plants, are embedded in the grain.
Under the action of the combs, the spikelets (panicles) are torn off and thrown to the header auger along the reflective and guiding surfaces of the deflector, roof, flap and cutter. A unit with a trailed grain harvester of this model can include tractors of traction class 1.4-2.0, a trailer with a carrying capacity of 2 tons. The function of the header auger ensures the collection and simultaneous supply of the combed heap of plants to the feeder chamber conveyor of the machine.

Trailed combine harvester

A trailed combine harvester (grain or forage harvester) is designed for harvesting, primary processing and loading of various agricultural crops. It is widely used on small lands and in areas with difficult terrain. The range of combine harvesters is very diverse depending on the manufacturer, purpose, technical parameters and productivity. Trailed combine harvesters do not have a power plant or a self-propelled chassis - they are aggregated with other agricultural machines. The torque to the drive of the main mechanisms is transmitted from the power take-off shaft of the tractor. On modern technology, the drive is hydraulic.

Forage harvester KDP-3000 "Polesie"

The Belarusian trailed forage harvester KDP-3000 “Polesie” mows different types of forage crops in the full phase of their ripeness. The machine ensures precise mowing of corn and sunflowers, followed by loading and transportation.

The model of the unit for harvesting forage crops KDP-3000 “Polesie” is capable of being aggregated with various modifications of tractors of traction class 2-5, the power of the power unit of which is 150 - 250 hp. The tests carried out showed a number of advantages of this machine.

The model is equipped with a drum-type header, which ensures high-quality corn harvesting without restrictions on the height of the stalks and loss of cobs. The trailed forage harvester provides excellent chopping of forage crops in the process of feeding the stems into the feeder mechanism.

The KDP-3000 “Polesie” model is equipped with an effective metal and stone detector and a device that ensures instant stop of the feeding apparatus. Thanks to the universal disc grinding device, a high level of quality can be achieved in grinding crop grains to the maximum extent, including crushing corn grains.

Model PN-100 “Prostor” and other types of grain harvesting machines

The purpose of the trailed model PN-100 "Prostor" is associated with the collection and threshing of cereal crops.
The combine is equipped with an axial rotary threshing and separating unit, providing a large separation area. This type of equipment is indispensable for carrying out agricultural work in fields with small contours. The axial type pre-threshing mechanism ensures clean threshing of grain. The design of the PN-100 “Prostor” model has fundamental differences from those found in other models of grain harvesting units, for example, “Don 1500”. The successful combination in the PN-100 “Prostor” model of new and used parts and components of the SK-5 “Niva” combine, produced in series, makes the machine more functional. The PN-100 “Space” model is aggregated with tracked and wheeled tractors of traction classes 1.4-2.0.

Ease of operation with a high degree of unification allowed the PN-100 “Prostor” model to take a reliable position among the leaders.

The technical characteristics of other mechanization equipment for harvesting grain crops are not inferior to the PN-100 “Prostor” model, the cost of which is 8.7 million rubles. For example, the Yenisei-1200-1NM grain harvester belongs to the group of self-propelled machines for harvesting grain, legumes and cereal crops. The cost of grain harvesting mechanization is 5.89 million rubles.

If you choose the Challenger model line, then each machine is equipped with special innovative equipment that allows you to achieve the most comfortable conditions when carrying out agricultural work.
