Grain dust removal device

Abstract

The invention discloses a grain dust removal device. The grain dust removal device comprises a screening box, wherein the top right corner of the screening box is provided with a feed port, the innerportion of a fan case is provided with a fan, the inner portion of the screening box is provided with a filter plate, the upper surface of the filter plate is provided with a baffle, the lower surfaceof the filter plate is provided with a first dust falling groove, the left end of the first dust falling groove is connected with a second dust falling groove, the upper surface of the left end of ascreening plate is provided with a limiting rope, the inner portion of a motor box is provided with a motor, the shaft portion of the motor is connected with a half gear, the half gear is meshed witha tooth discharging plate, the grain slides off from the filter plate, a part of the dust is fed into the first dust falling groove through the action of the filter plate, and then passes through thesecond dust falling groove, so that the part of the dust finally falls into a first dust collection box for unified treatment. In order to control the falling speed of the grain, the surface of the filter plate is provided with a plurality of impellers, and the rotation of the impellers is driven through sliding-down of the grain, so that the descending speed slows down, thereby being capable of performing filtration better.

Description

technical field [0001] The invention relates to the technical field of dust removal devices, in particular to a grain dust removal device. Background technique [0002] "Grain" covers a wide range, including rice, wheat, millet, soybeans, etc. and other miscellaneous grains. Cereals include rice, wheat, millet, soybeans, etc., mainly plant seeds and fruits. It is the traditional staple food of many Asian peoples. Cereals do not only refer to the seeds of gramineous plants. To be precise, they can be roughly divided into three categories in my country: Cereals: including rice (indica rice, japonica rice, and rice), wheat (wheat , barley, oats, rye), corn, sorghum, millet, millet, yellow rice, buckwheat, etc.; legumes: including soybeans, broad beans, peas, mung beans, red beans, kidney beans, etc.; potatoes: including sweet potatoes, also known as sweet potatoes Or sweet potato, potato, yam, taro, cassava, etc. [0003] With the acceleration of the pace of industrialization ...

AI Technical Summary

Problems solved by technology

[0003] With the acceleration of the pace of industrialization in our country, the degree of mechanization of agricultural production is getting higher and higher. Harvesting grains is basically done by mechanical harvesting. In many cases, soil particles or fine dust in the land will be harvested and bagged together with the grains. However, the current harvesting Grain machinery, such as rice or wheat harvesters, does not have a dust removal system, so the cleanliness of the grain cannot be guaranteed
