The invention relates to agricultural and household machinery and can be used in the construction of a combine harvester.

The purpose of the invention is to increase the performance and reliability of work.

1 shows a diagram of a combine harvester, side view; figure 2 is the same, top view; on fig.Z - section aa-a on figure 1; FIG. 4 shows a pumping grain distributor; FIG. 3 is a flow chart of a combine harvester; Fig, 6 - section BB in Fig.Z; Fig. 7 shows a device for the chopping of ears; Fig.8 is a diagram of a rotary shears.

The combine harvester has a housing 1, in which a threshing machine 2, a receiving 3 and a chipper 4-biters, a keyboard straw walker with 3, wind-cleaning with a transport board 6, a fan 7 and sieves 8, a grain screw 9 with an elevator 10 and a gray head are installed. auger 11 with an elevator 12, elevators 10 and 12 communicate with the unloading auger 13, located horizontally above the grain box 14 attached to the side of the combine, in the form of a self-unloading vehicle.

At the OUTPUT end of the discharge auger 13, a swinging distributor 13 of grain from the hydraulic drive of the combine is installed, and inside the casing 16 there is a half-shaft 17 deck with reefs. Above deck 17 on shaft 18 a removable spir is installed with elastic sleeves 19; a zonal part of auger 20 is made on the basis of a hollow shaft 21. The outer edge of the helix has a rough surface. Shaft 21 and removable helical portion 20 are interconnected by radial stud 22.

The casing 16 in the middle part communicates through a control valve 23 with a vertical pipe 24, in the lower part of which a rotary valve 23 is installed. The latter is rotated by the drive of the fan 7 by means of a chain gear 26 and a pair of conical wheels 27,

In front of the housing 1 attached pickup 28 with an inclined conveyor 29 and the hydraulic cylinder 30 of the rise. There is also a detachable spoke 31 with a cardan transmission 32 from the power take-off shaft of the tractor, the main cone box 33 of the drive — mechanisms of the combine, the transfer box 34, and also the side box. the bracket 35 with the transmission 36 and the conical box 37 of the drive unloading device of the grain tank 14.

The wheel drive 38 is made uniaxial with twin wheels, which are installed under the body of the combine I and are located on the same line of the wheel of the grain tank 14. Wheel drive 38 is connected to the body 1 of the thresher through frame 39. At the bottom of the wheel travel 38 there is a crinkle on the hoop earring 40. On the left side of the wheel drive 38 is installed the hinge coupling 41 and the spacer tube 42, and on the right side there is an asterisk 43 dp of the wheel drive.

Behind the keys of the straw walker 3 there is an inclined chain-slat conveyor 44, for non-grain Maya, and below it is a stacker 43 dp of straw mixed with the floor. Stacker

43 is quickly mounted with four screw locks.

Combine harvester works as follows.

When the combine moves from the tractor's power take-off shaft, the drive shaft 3 of the transmission 3 and the main cone box 33 are rotated, from which all the mechanisms of the combine get moving. The grain mass supplied to the pick-up 28 is fed by the inclined conveyor 29 into the threshing machine 2. In the process, the height of the pick-up is adjusted by the hydraulic cylinder 30. The receiving 3 and the bumper 4 beaters facilitate the direction of the grain mass into the threshing drum and straw removal to the straw walker from which the straw enters the conveyor 44 and further into the stacker 43,

The mixture of grain and chaff from the threshing apparatus is fed to the transport board 6 and through it to the sieve 8. After cleaning, the grain enters the grain auger 9 and is transported through the elevator 10 to the output part of the load auger 13, and from there by way of the grain distributor 13 - The Polvo hopper 1 attached to the side of the combine, consisting of mink and bunker, comes down from the top sieve 8 of the cleaning and in the mixture with straw along the conveyor

44 falls into the stacker 45 in the form

falling stream4 Another part of the sieve debris, consisting of mungling, free grain and undersize products, passes through the extension of the upper sieve 8 into the ear screw 11 and the elevator 12 is transported to the inlet part of the unloading screw 13, where it is rubbed between the floor with a fluxed corrugated deck 17 and the spiral part of the screw 20, having a rough working edge. Since the helical portion of the screw 20 is mounted on the drive shaft 18 by means of elastic sleeves, the heap is rubbed gently without damaging the grain. A small fine grain heap moving inside the casing 16 can be served in two directions. When supplying the pile for cleaning, it is directed to the vertical pipe 24 and the rotary shank 25 is thrown onto the transport board 6. When applying a small pile in the direction of arrow C, the control valve 23 is in the open position. Selected grain nocTynaet in the grain auger 9 and further along the elevator 10 into the unloading auger 13, and the meter goes in the direction of the arrow B to the conveyor; 44 and further into the stacker 45.

When feeding the grain and wiped heaps into the grain bunker 14, it moves from the arrow E. In this case, the valve 23 should be moved to the left position, blocking the grain heap passage to the vertical pipe 24.

Depending on the working conditions in the hopper 14, it is possible to collect grain with different content of land. For this purpose, the valve 23 is set in the actuated position. The absence of a grain bunker, a propulsion system, a cab, and a drive axle on the combine not only drastically reduces the weight of the machine, but also raises the thresher, while maintaining the adopted dimensions. This allows the wheel drive 38 to be installed under the thresher, to simplify the conveyor 44 for feeding straw and chaff into the stacker 4 as well as the feeding and distribution of grain

in the trailed bunker 14. Location 55 counter,

the rear wheels of the bunker 14 in line with the wheel travel 38 KOM6afiHa, as well as the use of a spacer pipe 42 with an articulated joint 41 provides rotation with a minimum radius. When operating in difficult conditions, for example, on hoists, it is possible to connect the right drive wheels of the combine to the straight sections of the movement by means of an open chain transmission 43 connected by a clutch to the combine transmission.
