Proposed collecting hopper, first radically solves the problem of improving the performance of this type of devices, the automation process of feeding solid fuel or solid bulk material to feeders of different type and serves to eliminate bridging, hovering and truboobrazovaniya solid fuel or solid bulk materials, sticking of the wet material to the hopper walls, freezing, clumping, and to regulate the flow rate and the amount of the solid fuel or solid loose material from a hopper to feeders and conveying devices. The larger the mass of material, the more intense is the process of breaking up. The entire mass of the solid fuel or solid bulk materials, in a rotary hopper is in constant motion, pour on the hopper walls loosened while moving to the unloading hatch. Weight of the solid fuel or solid bulk material is high enough, and the stirring and movement of the layers leads to defragment lumps, and increasing the flowability and transportability to the opening for discharging. Sticking to the hopper wall is not due to simultaneous movement of the entire mass of the solid fuel or solid loose materials in the hopper walls in the transverse direction with simultaneous longitudinal displacement.
