A hopper of a grain combined harvester with a wall inclined relative to the horizon which is disposed on a frame rigidly fixed to the body of combined harvester. The construction of the frame includes a supporting platform, to which, on the right side, bracket supports are rigidly fixed, the other, free, end of which is connected with the hopper by hinges, and a hydraulic cylinder is connected to the frame by hinges on one side, and on the other side is connected to a wall of the hopper, inclined relative to the horizon, by hinges, while unloading the grain, a mechanism of turning the hopper as regards to the body of combined harvester, a lid of the hopper, which is made as a U-like channel with boards sloped outside, which in one position covers the upper part of hopper and embraces the hopper from the front and behind, and in the second position provides sliding out of the tank grain along the U-like channel into a transport vehicle. The angle of inclination of the wall relative to the horizon exceeds the largest angle of friction along the surface of the wall. The hopper is equipped with a circuit with a flexible membrane preliminary tensioned, made of an elastic material, the circuit is fixed along the internal perimeter of the hopper reservoir towards the opposite ribs. |
