Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal feeding hoppers, and specifically relates to a rice feeding hopper capable of removing dust. Background Art

[0002] The most commonly used structural forms of the lower hopper are the spiral groove cylindrical hopper and the conical hopper. As auxiliary equipment in the conveying system, it plays the role of connecting and coordinating the crane and belt conveyor system.

[0003] During the production process of rice, a feed hopper is required to allow the rice to enter the processing machine through the feed hopper. For example, Chinese utility model patent CN209226064U discloses a rice feed hopper with a screen, which is mainly composed of two parts: a conical hopper and a connecting pipe, and is movably connected by a thread. When unloading, the protective cover is opened. When the protective cover is sealed, it completely covers the inlet of the conical hopper and protects the inlet through an outer gasket to prevent wear. Then the rice enters from the inlet and falls into the unloading hose inside the conical hopper. The design of the raised part serves to connect adjacent unloading hoses and facilitates the rice to fall evenly into each group of hoses. The unloading hose is locked in position in the conical hopper by a fixed disk and inserted into the hose limit hole. The limit holes of the hose are located at different positions of different horizontal lines, and are connected to make the feeding hose spiral. The rice will slow down when falling in the feeding hose. At the same time, the soft texture of the hose will reduce the force of collision and protect the rice. Then the rice will continue to fall and fall onto the guide plate structure in the connecting pipe. The two sets of side baffles act as a barrier to prevent rice grains from splashing out. A screen is laid on the guide plate structure. The aperture is smaller than the size of the rice, but slightly larger than the diameter of general broken rice. When the rice rolls on the guide plate structure, the broken rice and impurities therein will directly pass through the mesh holes and fall into the waste collection cavity inside the guide plate structure and be collected. After the feeding operation is completed, the cover of the waste outlet is opened to release the waste, which is more practical.

[0004] Although the above-mentioned prior art can screen and protect rice, it is unable to remove dust existing on the rice before production, which will cause the rice with dust on the surface to enter the interior of the processing device, causing the processing device to be contaminated, and the processed rice will still contain dust.
