The combine harvester's bunker has a cylindrical body 1 in which a hollow shaft 4 is mounted with the screw auger 2 and truncated hollow cone 8 fixed to it by means of appropriate brackets. The larger base of the cone 8 faces the unloading conveyor in the form of the lower screw 10. Forming cone 8 is inclined to the horizontal at an angle α natural grains. The surface of the cone 8 is made with a longitudinal through groove 9, the longitudinal axis of which is located in a plane passing through the axes of the housing 1 and the screw 2. Inside the hollow shaft 4 a solid shaft 5 is mounted, which by means of gear 12 is connected to the screw shaft 2, as well as drive element 11 of the rotational drive of the screw 2 around its own axis. The end of the shaft 4 is connected with the drive element 13 of the rotational drive of the screw 2 and the cone 8 around the axis of the housing 1. In the upper part of the hopper, the feed conveyor in the form of the screw 15 is installed. When unloading grain into the hopper, the screw 2 rotating around its axis is mounted It doesn’t have the function of grain distribution, moving it from the screw 15 to the opposite wall of the bunker, as well as through the groove 9 to the inside of the cone 8. To unload the bunker, they first turn on the screw 10. As the grain is unloaded by the screw 10, the grain spontaneously moves into the emptying space about from the cavity of the cone 8. The rotation of the screw 2 around its own axis accelerates this movement. The remaining grain is unloaded due to the rotation of the screw 2 and the cone 8 around the axis of the housing 1. 1 Cc. f-ly, 2 ill.

The invention relates to agricultural machinery, can be used in the design of a combine harvester bunker and is complementary to the basic one by the author. St. No. 1424760.

The purpose of the invention is to intensify the process of unloading the bunker and reducing the injury to the grain.

FIG. 1 shows a hopper diagram, a longitudinal section; in fig. 2 - section A - A in FIG. one.

The hopper of a combine harvester contains horizontal auger 2 mounted in a cylindrical housing 1, the shaft of which is mounted on brackets 3 rigidly connected with an IO: 1st shaft 4 mounted in housing 1 coaxially with its horizontal axis. Inside shaft 4, a solid shaft 5 is mounted. On the hollow shaft 4, by means of brackets 6 and 7, a truncated hollow cone 8 rigidly mounted, placed in housing 1 coaxially and made with a maximum through groove 9, the longitudinal axis of which is located in a plane passing through the axes hull and stalk 2. Forming cone 8 is inclined to the horizontal at an angle of natural shedding of grain (), while the base of the cone 8 faces the unloading conveyor made in the form of 1 st 10 which is installed in the lower part of the bunker. At the outer end of the splicing shaft, the actuator 1 1 of the drive of the screw 2 auger 2 is mounted around its axis, the shaft of which is connected to the shaft 5 by transmission 12. One end of the hollow shaft 4 is passed through the housing 1 and connected Screw the auger 2 and the cone 8 around the axis of the housing 1. In the upper part of the housing 1, it is made ok} 1о 14, above which on the side of the housing 1 is fixed the feed conveyor made in the form of the screw 15, enclosed by the casing 16 and connected to the elevator 17.

The device works as follows.

The grain is fed into the bunker by the elevator 17 and unieKOM 15 through the window 14. When the silo is filled with grain, the screw 2 is set in the upper position. At the same time he is in

It is distributed and rotates around its own axis. The screw 2 moves the grain from under the screw 15 to the wall of the housing 1 opposite to the window 14, including into the cone 8 through the through groove 9.

When the grain is unloaded from the hopper, the screw 10 is first rotated. After the grain is unloaded from the zone adjacent to the intake part of the screw 10, the grain from the cone 8 cavity moves into the empty space. After the grain is partially unloaded from the hopper, the screw 2 is rotated around its own axis, which accelerates the movement of grain from the wall of the hopper along the cone 8 to 10. Then rotate around its own axis 2 and cone 8 will mix around the axis of the body 1, which allows the remaining grain to be moved to the screw 10.

The use of the cone 8 bunker in its construction, the surface of which is made at an angle of natural grain crumbling and which, together with the screw 2, is rotated around the axis of the housing 1, allows the unloaded grain to spontaneously move from the volume of the hopper contained inside the cone 8, which reduces the injury of the grain to the 8 and increases discharge capacity
