Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wheat processing, more specifically, a kind of suction type specific gravity grading stone removing machine for wheat processing. BACKGROUND

[0002] Wheat stone removal refers to the removal of stones in wheat to ensure the quality of wheat and the smooth progress of subsequent processing. The wheat stone removing machine is a device specially used for this purpose, which can effectively remove stones similar in size to wheat particles, thereby reducing the sand content of flour and ensuring the quality of flour.

[0003] Patent No. CN221472454U discloses a rice finishing step type suction stone removing machine, which includes a stone removing machine main body. The rice flows on the first screen, and the stones fall through the first screen onto the first stone removal plate and then fall onto the second screen, and the remaining stones fall through the second screen onto the second stone removal plate and then fall out. During this process, the air pump creates negative pressure in the first and second suction plates. By taking advantage of the different physical properties of grain and stone, such as specific gravity and suspension speed, and the effect of air flow passing through the gap between grain particles, the grain and stone are classified, making it easier to remove stones. The first and second cleaning brushes are moved by the first and second electric telescopic rods. The first and second cleaning brushes can clean the first and second screens to prevent the first and second screens from being clogged by rice or stones.

[0004] However, in Patent No. CN221472454U, rice is injected into the inside of the shell through the feed hopper, and then falls onto the first screen. The rice flows on the first screen, and the stones fall through the first screen onto the first stone removal plate, and then fall out through the first discharge plate. Since the material mainly flows through the board material set at an inclined angle, the material cannot be evenly distributed on the surface of the board material, which is not conducive to screening, and the material is aggregated together, which makes the material suspended by negative pressure less effective, and there is room for improvement. Therefore, we propose a suction type specific gravity grading stone removing machine for wheat processing to solve the above problems. Utility model content
