Automatic grain impurity removal device

Abstract

The invention discloses an automatic grain impurity removal device, and relates to the technical field of grain impurity removal, the automatic grain impurity removal device comprises a mounting rack, an impurity removal box arranged at the top of the mounting rack, a shelling box arranged at the top of the impurity removal box and a shelling box arranged at the top of the shelling box in a communicating manner, a receiving hopper is mounted at the bottom of the impurity removal box, and splitter plates are arranged on the two side surfaces of a longitudinal beam; an arc-surface-shaped rolling groove is formed in the top surface of the bearing plate; a rolling mechanism is arranged in the rolling groove; a one-way transmission assembly is arranged in the middle of the bottom face of the bearing plate. A shifting mechanism is arranged in the lower part of the receiving hopper; according to the device, the grinding mechanism is matched with the transmission assembly and the shifting mechanism, so that automatic hulling, impurity removal and automatic sorting operation can be conveniently carried out on hulled and impurity-removed grains, the convenience of hulling, impurity removal and particle sorting operation on the grains is effectively improved, and the efficiency of impurity removal on the grains is greatly improved; and meanwhile, small grains in the grains can be conveniently sorted out, and the finished product quality of the grains after impurity removal operation is improved.

Description

technical field [0001] The invention relates to the technical field of grain impurity removal, in particular to an automatic grain impurity removal device. Background technique [0002] my country is a big country in the grain industry, with an annual grain output of 500 million tons. After the grain is harvested, threshing, drying, storage, transportation, and processing are required. Therefore, before grain storage and transportation, it is often necessary to dry the grain. During the drying process, it is necessary to remove the husk of the grain first, so as to avoid the chaff on the grain and impurities such as straw, dust, and grain mixed in the grain from affecting the fluidity of the grain, so that part of the grain cannot be circulated well, resulting in The grain is dried unevenly; therefore, before the grain is dried, it is often necessary to remove the impurities contained in the grain; [0003] When the existing grain impurity removal device is used, it is not on...

AI Technical Summary

Problems solved by technology

[0003] When the existing grain impurity removal device is used, it is not only prone to blockage, but also only has the effect of screening out impurities on the grain, and cannot perform husk operation on the grain with husks, so a separate husk machine is required Carry out shelling operation on the grain, and at the same time, it is impossible to record the grain sorting operation of the shelling and impurity removal process, and it is easy to appear that the full-grained grain is mixed with poor-quality grain, which will affect the final product quality of the grain; therefore, it is necessary to Solve the above problems
