Problems solved by technology

[0004] The above-mentioned patent has the following disadvantages. It adopts a spiral screening slide, and the spiral screening draws that because of its structure, the size of the screen holes on it is the same, and cannot meet the needs of multi-stage screening. Therefore, further improvement is required.

Abstract

The invention discloses a screening device with a dust removal function for rice production, and relates to the technical field of rice screening. In order to solve the multi-stage screening problem, the device specifically comprises a base, a throwing type conveying mechanism, an impurity removing mechanism and a screening mechanism are sequentially arranged on the outer wall of the top of the base according to the rice path, the screening mechanism comprises a screening shell and screen plate assemblies which are oppositely arranged in the screening shell in a staggered manner, and each screen plate assembly comprises a screen mesh and a screen mesh; and the screen meshes are rotationally connected with the outer walls of the opposite sides of an impurity guide plate, and the outer wall of the other side of the impurity guide plate is fixedly connected with the inner wall of the screening shell. On one hand, the device can replace a filter screen, is simple in structure and reduces the cost, on the other hand, when rice subjected to wind power transversely moves, the rice can collide with an inclined baffle, the collided rice can continuously collide with other rice grains, the confusion degree of falling of the whole rice is increased, therefore, gaps between the rice are increased, and the dust removal effect is better.

Description

technical field [0001] The invention relates to the technical field of rice screening, in particular to a screening device for rice production with dust removal function. Background technique [0002] my country is a large agricultural country, and rice is an important part of the agricultural composition. Rice is the finished product of rice after cleaning, husking, rice milling, and finished product finishing. After the rice is harvested, it is mixed with grain husk , crumbs and soil particles and other sundries need to be screened before processing. [0003] After retrieval, the Chinese Patent Publication No. is CN112156983A, which discloses a rice screening device for rice production, including a screening bin: the top of the screening bin is provided with a feed bin, and the inside of the feed bin is provided with a regulating The adjustment component of the rice blanking thickness, the inside of the screening bin is provided with a hollow and spiral screening slide, an...
