grain cleaning machine

Abstract

The invention discloses a grain cleaning machine. The machine comprises a feeding channel, one end of the feeding channel is provided with a feeding port, the other end of the feeding channel is provided with a discharging port, and the feeding channel is obliquely arranged downwards from the feeding port to the discharging port; the machine further comprises a pair of feeding rods, wherein the feeding rods are arranged in the feeding channel in parallel, and the feeding rods are arranged in the feeding channel in a manner that the feeding rods can move back and forth relative to the feeding channel; each feeding rod comprise a strip-shaped plate body and a plurality of fins arranged on the strip-shaped plate body, and the fins are made of soft plastic sheets; the length of the fins is greater than one half of the distance between the pair of strip-shaped plate bodies; the machine comprises a pair of feeding power mechanisms, the feeding power mechanisms are used for driving the pair of feeding rods to move in opposite directions; the machine comprises a dust removal air flue, one end of the dust removal air flue is connected with one end of the feeding channel, and the inclinationdirections of the dust removal air flue and the feeding channel are opposite to each other; and the machine comprises a draught fan, and the draught fan is arranged at the other end of the dust removal air flue. According to the grain cleaning machine, efficient dust removal of the grains is realized, and the cleanliness of the grains is improved.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a grain cleaning machine. Background technique [0002] With the continuous development and technological progress of grain, edible oil processing and grain storage industries, higher requirements are put forward for the quality of grain cleaning and the processing capacity per unit time. Before the grain is put into storage, it needs to be cleaned of impurities, such as leaves, chaff, dust and shriveled grains, etc., to improve the cleanliness of the grain, improve the quality of the grain, facilitate the storage of the grain, and avoid the deterioration of the grain due to the sundries. Guarantee the shelf life of food. Existing grain cleaning devices usually use a grain cleaning sieve, and use a vibrating sieve to sieve and clean the grain. During the sieving and cleaning process, a large amount of dust gas will be discharged together with the sifted grain, affecting the cleanliness ...

AI Technical Summary

Problems solved by technology

Existing grain cleaning devices usually use a grain cleaning sieve, and use a vibrating sieve to sieve and clean the grain. During the sieving and cleaning process, a large amount of dust gas will be discharged together with the sifted grain, affecting the cleanliness of the grain. At the same time, it will pollute the environment and affect the health of the staff

The existing grain cleaning sieve cannot effectively remove the impurities in the raw grain, light impurities and dust are difficult to separate and settle from the grain, the impurity rate of the grain is high, the dust is flying during the grain cleaning process, and the air pollution is serious
