Full-closed negative pressure type automatic grain sorting machine

Abstract

The invention provides a fully-closed negative pressure type automatic grain sorting machine, and relates to the technical field of grain sorting, the fully-closed negative pressure type automatic grain sorting machine comprises a bottom plate, a pretreatment box is welded above the bottom plate, the outer surface of one side of the pretreatment box fixedly communicates with a sealing opening through bolts, and a communicating pipe is fixed to one side of the sealing opening; according to the device, when a user collects impurities, the limiting pieces can be taken out of the limiting plates through the grips, then the user takes the limiting strips out of the limiting pieces, the limiting strips can be taken out of the limiting pieces, and therefore the impurities can be collected conveniently, and the impurities can be collected conveniently. According to the device, a user can take down the collecting net and replace the collecting net, during replacement, the front end of the collecting net is placed above a limiting piece and fixed in the limiting piece through a limiting strip, then the limiting piece is installed in a limiting plate again through a grip, and the efficiency of replacing the collecting net by the user is improved.

Description

technical field [0001] The invention relates to the technical field of grain sorting equipment, in particular to a fully enclosed negative pressure automatic grain sorting machine. Background technique [0002] The grain coming out of the harvester often contains impurities such as fine soil, grain stalks, grain bran, shriveled grains, damaged grains, etc. It has brought great troubles. Therefore, it is necessary to screen and separate the harvested grain to remove the fine soil, grain stalks, grain bran, shriveled particles, damaged particles, etc., so that the staff can store the grain and our own consumption. [0003] However, during the working process of the existing negative pressure sorting machine, the feeding method of directly absorbing the existing grain is usually adopted to sort the grain, but the grain stored now has a great possibility of making the The agglomerated grain cannot be sucked into the interior of the device, which reduces the strength of the dev...

[0002] The grain coming out of the harvester often contains impurities such as fine soil, grain stalks, grain bran, shriveled grains, damaged grains, etc. It has brought great troubles. Therefore, it is necessary to screen and separate the harvested grain to remove the fine soil, grain stalks, grain bran, shriveled particles, damaged particles, etc., so that the staff can store the grain and our own food

[0003] However, during the working process of the existing negative pressure sorting machine, the feeding method of directly absorbing the existing grain is usually adopted to sort the grain, but the grain stored now has a great possibility of making the The agglomerated grain cannot be sucked into the interior of the device, which reduces the strength of the device for sorting the grain
