Grain dust and impurity removing system

Abstract

The invention discloses a grain dust removal and impurity removal system, which includes a linear reciprocating push mechanism, a screening mechanism and an optimal collection device. The linear reciprocating push mechanism is an incomplete gear transmission mechanism. The machine and the dust filter bag, the linear reciprocating push mechanism drives the sieve plate to move, the impurities in the grain are captured and deposited by the exhaust fan and the dust filter bag, and the grain after the impurity removal is further separated and collected by the air flow in the optimal collection device. The beneficial effect of adopting the present invention is that the grains pass through the screening mechanism and the optimal collection device successively to realize the impurity removal and selection of the grains, and the device system is simple and effective and easy to maintain.

Description

technical field [0001] The invention relates to a grain processing device, in particular to a grain dust and impurity removal system. Background technique [0002] With the development of agricultural intensification and scale, agricultural machinery is used more and more widely. The grain harvested by machinery contains a lot of stones, grass seeds, shriveled grains, straw fragments, etc. At the same time, because the grain is also mixed with a lot of dust, it is easy to be dusty in the subsequent processing process, which makes the production environment worse and affects the grain. quality. Large-scale grain screening devices currently on the market generally have complex structures, take up a lot of space, and have high prices and maintenance costs, and are not suitable for promotion and use in small and medium-sized farms. Therefore, it is necessary to design an impurity removal device with simple and compact structure, low price, easy use and maintenance. Contents ...
