The invention relates to the storage and unloading of bulk materials using bins and can be used in food, construction, chemical and other sectors of the economy.

The purpose of the invention is to intensify the release of material.

The drawing shows a hopper for hard-flowing materials.

The bunker for hard-flowing materials contains a vertical body 1 with a conical lower part 2 and an exhaust hole 3, as well as a lid 4 with a feed funnel 5. Inside the body 1 coaxially and rotatably mounted 6 is a skimmer 6, repeating the profile of the hopper. The chipper 6 is made in the form of a spiral pipe supported on the conical part 2 of the housing 1 in the form of a spiral with holes 7 and 8 made in the lower part of the spiral turns. The openings of adjacent turns are arranged in a checkerboard order, and the axes of the holes of one turns are tangential to the circumference of the lower turn pipe’s tube on the outer side, and the axes of the adjacent turns are tangential to the circumference of the lower turn pipe’s inner tube . The lower end 9 of the pipe is closed by a stopper 10, and the upper end 11 is open for supplying compressed air: and mounted in a sliding bearing 12, for example, from compacted modified wood. A layer of antifriction coating is applied to the inner surface of the conical part 2 of the housing 1, for example, in the form of a thin film 13.

The device works as follows.

When working in the housing 1 through the feed funnel 5 serves the processed material and at the same time through the holes 7 and 8 compressed air supplied into the cavity of the pipe. At the same time, the air flows, blowing each subsequent turn of the spiral of the demolisher 6 from all sides, blow off the recycled material from the surface of the turns of the spiral, which tries

to settle or stick to the surface of the turns of the spiral (upper half of the turns) and at the same time do not allow the “base” of the arch of the material being processed to form in the near-wall sections of the bunker. Then the billet 6 is rotated, for example, in the direction opposite to the spiral winding. In this case, the turns of the water crusher 6, moving along the housing 1. Contribute to the movement to the outlet 3 of the processed material, acting as a screw conveyor. Air streams flowing through the openings 7 and 8 of the moving turns of the spiral of the demolisher 6 at the same time make it impossible to form the central part of the roof of the material. As a result, the material to be processed enters the outlet 3 in a continuous flow.

The proposed bunker for hard-flowing materials provides increased reliability by eliminating sedimentation and sticking to the turns of the coil breaker of the material being processed and the occurrence of "stagnant" zones in the near-wall areas.
