Elastic elements made in the form of helical springs 30 mounted on a through bolt 31, which is connected to the sides 21, are placed between the bar 22 and the flanges 21. Hydraulic shock absorbers 33 are hinged to the flanges 21 on the slat 22 by means of a hinge 32.

3 and the axis of connection of the sections 9, 10 are located on the same vertical axis. Section 9 and 10 of the conveyor are, respectively, conveyor belts 36,

37, housed in shells 38, 39. In the articulation zone of the grain conveyor belt, the shells 38, - 39 are provided with pockets 40, 41, respectively, which are overlapped for

preventing the loss of grain in this zone. The angle of the solution of each of the pockets 40, 41 is not less than the angle of the solution of the limiter sector 19. The pockets 40, 41 are formed by the sector projections 42, 43, respectively. The protrusion 43 is connected to the casing 39 pivotally to allow relative movement of the sections 9, 10 in the vertical plane. To prevent the shields, each of them

44 is fixedly mounted on the side noJiKe of the casing 38, and the other is made with the possibility of free sliding along the limiting rods 45, gaar, fixedly mounted on the casing 39. To eliminate kinks with the relative movement of the sections 9, 10 in the vertical plane, the sheet 44 is made of three parts (not shown) hingedly connected to each other at the junction of sections 9 and 10. In the upper shelf of the casing 39 there is a closable window (not shown) for installation work and an internal inspection of the joint area. The housings 38, 39 in this zone can be covered with a corrugated cover (not shown) from above.

Grain bunker 8 can be made of open-top containers 46 installed inside the bunker case. The rear section 10 of the grain conveyor is made with a section 47 located above the containers 46, in which along its length the output windows 48 are made with shutters 49, each of which has controls with hydraulic cylinders 50.

Each container 46 has a grain level sensor (not shown) associated with the hydraulic cylinder 49 of the flap 50 of the corresponding exit window 48.

A support bar 5 is disposed along the side of the bunker 8 for unloading containers 46. The upper portion 47 of the rear section 10 of the grain-feed conveyor is mounted on brackets 52.

Each container 46 is equipped with a device for lifting and tilting, which has a U-shaped frame 53 with an upper shelf and side plates 54. A finger 55 is mounted on each bar 54 located in a slot 56 of sector 57 fixed on the front and rear walls of the bracket 46. Plank 54 is connected to these walls by means of a hinge 58 located above the center of gravity of the container 46 filled with grain. To prevent premature tilting of the container 46, a stopper 59 is provided, mounted on the side plate 54 and containing a spring-loaded finger (not shown), one end of which is fixed in the hole of the bar 54 and the other is placed in the hole (not shown) of sector 57.

fixed sksba 60.dl hook 61 lifting device. On the bottom of the container 46, two hooks 62 are hingedly mounted for engagement11 with the rod 51 when the container 46 is tilted.

The container body 46 has a screening and can be made of

Q hard plastic, for example glass fiber reinforced foam.

The combine works as follows.

When the combine is moving in the straight line g-1I direction-limiter 19 is fixed from the cab 4 to ensure the normal operation of the grain feed conveyor. The springs of gee 30 and hydraulic shock absorbers 33 smooth out

20 shock loads caused by the relief of the floor. The lugs 34 are then extended to the working position. When transporting the stops 34 are derived from the working position, with the fixed

25, tractors 35 provide a large angle of folding for elements of the restrictor sector 19.

After filling with the grain of any container 46, the corresponding

2Q, the window 48 is blocked by a shutter 50 according to a signal from the level sensor to the grains. The containers 46 filled with grain are unloaded by a lifting device mounted on a combine, such as a crane beam, or an external loader. To do this, with a hook 61, the container is raised with a certain inclination in the direction of tipping, the hooks 62, while resting against the rod 51, increase the inclination of the container 46, after

when the stopper 59 is released, the finger 55 slides into the slot 56 of sector 57 and the container 46 is unloaded. The emptied container 46 is slightly raised, the hooks 62 are released from the rod 51, then the container 46 is lowered inside the housing of the hopper 8, while the stopper 59 is fixed.
