Operational Features

Before use, the feed dispenser should be run in for half an hour. You should start with low speed, and then switch to normal. The KTU-10 model is aggregated with the Belarus tractor.

The equipment is loaded with feed mass evenly. To distribute feed, you must turn on a special operating mode, and the gear lever must be moved to 1st or 2nd gear.

The vehicle body is designed so that feed distribution is possible on both sides of the body. For one-sided distribution, one transport sheet is required, and for two-sided distribution, two.

To use the feed dispenser as a transport device, the ratchet mechanism must be activated, and for self-unloading, a special arrangement of pawls and discs is used. This agricultural machinery allows you to regulate the supplied feed mass by changing the speed of the conveyor.

At sub-zero temperatures, the feed dispenser must be kept in a warm room to avoid the formation of ice on conveyors and other moving mechanisms.

The device of the feed dispenser KTU-10A

The feed distributor KTU-10A (Fig. 1) is a two-axle tractor trailer on springs and pneumatic wheels 15. The machine consists of a frame 1 with a body mounted on it, at the bottom of which there are two longitudinal chain-slat conveyors 10, designed to move a layer of feed from the rear 2 to the front 9 wall of the body.

For dosed feeding of feed, in the front part of the body, in front of the longitudinal conveyors 10, a block of beaters 7 is installed, behind which a transverse conveyor 16 is located.

The drive of the working bodies is carried out by cardan shaft 13 through kinematic transmissions from the power take-off shaft (PTO) of the tractor.

On the frame 1 with the chassis 15 there is a link 12, a braking device and electrical equipment. The hook 12 is connected at one end to a rotary hinge, and at the other there is a tow hook.

The rear wheels are equipped with hydraulically driven shoe brakes, which are controlled from the tractor driver’s cab.

The body is all-metal with a hinged tailgate 2. The bottom of the body is made in the form of a metal frame along which two pairs of chain-slat longitudinal conveyors 10 slide, forming two canvases. They serve to supply feed to the beaters 7.

The longitudinal conveyor (Fig. 2) consists of two pairs of chains 1, to which stamped transverse metal strips 2 are attached by means of a clamp 5, washer 4 and nut 3. Each pair of chains with strips forms a conveyor belt.

The conveyor belts are fixed by means of sprockets 6 on one drive shaft 7 and move intermittently, which ensures a uniform supply of feed to the beaters 8.

The drive shaft 7 of the longitudinal conveyor is located in the front part of the body and rotates in four plain bearings. It is driven into rotation from the lower beater shaft 8 through a crank mechanism.

In the front upper part of the body (see Fig. 1) there is a block of beaters 7, which is designed to uniformly supply feed to the transverse conveyor 16. The beaters are shafts with radial pins arranged in a checkerboard pattern and rotate in bearings mounted on the sidewalls 3 body

Also in front, but slightly below the longitudinal conveyor 10 and perpendicular to it, there is a transverse unloading conveyor (Fig. 3), which serves to supply feed to the feeders. It consists of a driving shaft 1 and a driven shaft 2, a rubberized tape 3 with strips. Can distribute feed into feeders located on one side or on both sides of the dispenser.

To distribute feed into high feeders, the dispenser is equipped with an additional conveyor, which is hung on the unloading part of the transverse conveyor. The additional conveyor is installed in the required position using a hydraulic mechanism and secured with supporting chains. If it is no longer needed, it will be dismantled.

Metered feed supply is ensured by a block of beaters. The beater (Fig. 4) consists of a shaft 1 with hexagonal disks fixed on it, to the planes of which a shell 2 is welded. To loosen the feed, fingers 3 are attached to the shell 2.

The rate of feed dispensing is regulated by changing the speed of the longitudinal conveyor 10 (see Fig. 1) and the forward speed of the tractor. The mechanism for regulating the amount of feed unloaded into the feeders consists of a crank and ratchet mechanisms, and a chain drive.

Rice. 4. General view (a) and diagram (b) of the beater block: 1 – shaft; 2 – shell; 3 – finger

The ratchet mechanism (Fig. 5, a) consists of a connecting rod 3, a ratchet wheel 5, an earring 2, movable 6 and fixed 8 pawls, springs for holding the pawls in a given position and a sector of the ratchet wheel 5. The speed of movement of the longitudinal conveyor depends on the number of ratchet teeth wheels 5, captured by working pawl 6 in one revolution of the shackle 2.

The longitudinal conveyor is driven by a crank ratchet mechanism from the tractor PTO. When the tractor PTO is turned on, the crank body 1 together with the linkage 2 rotates, through the connecting rod 3 the rocker arm 4 is set into oscillatory motion, on which the pawl 6 is attached, pressed to the ratchet wheel by a spring.

Ratchet wheel 5 is fixed to the drive shaft 7 of the longitudinal conveyor. When the connecting rod 3 makes an idle movement, the pawl 6 slides along the teeth of the ratchet wheel 5. During the working movement, the pawl 6 rests against the tooth of the ratchet wheel 5, thereby turning the conveyor shaft 7. The safety pawl 8 keeps the ratchet wheel 5 from reverse rotation.

The speed of the longitudinal conveyor, and therefore the amount of feed supplied, is regulated by changing the angle of rotation of the drive shaft of the longitudinal conveyor, i.e., by changing the number of working teeth of the ratchet wheel 4 (Fig. 6). The latter depends on the position of disk 3.

Setting the ratchet mechanism to the feed dispensing rate is done by installing the ratchet wheel casing lock in the sector opposite the corresponding scale division. In this case, the pawls associated with the crank mechanism rotate the ratchet wheel to the required angle for each stroke.

For example, in the “max feed” position, the movable pawl 2 will engage with the wheel earlier than in other positions: the number of working teeth is greatest, which means that the speed of the longitudinal conveyor is also greater.

The ratchet mechanism ensures the movement of the longitudinal conveyor forward when distributing feed and backward when the feed dispenser is operating to transport various loads. To convert the feed dispenser into a self-unloading trailer, it is necessary to install pawls 2, 5 and disk 3 according to the diagram (see Fig. 6, b) and fix lever 1 in the “Back” position. Before unloading, you must open the tailgate and use spacers to set it in the open position.

The working parts of the dispenser are driven from the tractor power take-off shaft through the cardan shaft 1 of the feed dispenser (Fig. 7). Rotation from the cardan shaft 1 is transmitted to drive 2 and, through a chain transmission 3, to the drive shaft of the transverse conveyor 4.

The drive shaft 2 is connected to a bevel gearbox installed under the bottom of the body, from which rotation through the longitudinal shaft and chain drive 5 is supplied to the lower beater shaft 6. A second sprocket is installed on the lower beater shaft 6, connected by a chain drive 7 to the upper beater 8.

On the shaft of the lower beater 6 (see Fig. 7) there is a connecting rod 1 (see Fig. 1), which transmits rotation to a ratchet wheel mounted on the intermediate shaft.

A sprocket 9 mounted on the intermediate shaft on the opposite side transmits rotation to the drive shaft of the longitudinal conveyor 10.

The kinematic diagram of the drive of the working parts of the feed dispenser is shown in Fig. 7, b. The feed dispenser drive includes a cardan shaft, a dispenser drive shaft, drives for transverse and longitudinal conveyors and beaters.
