Small-size oscillation grain dehuller

Abstract

The invention discloses a small oscillating grain hulling machine, which comprises a frame, an oscillating mechanism, a screening mechanism and an air outlet mechanism. The air outlet component and the damper component drive the vibration component to run through the driving component. After the vibration component pushes the screening net in the screening component to a high place, the screening net drops rapidly by gravity, throws the grain on the screening net into the air, and is removed by the wind component. Light impurities such as chaff in the grain, and then the grain is returned to the screening net, and the granular impurities in the grain are screened and removed by the screening net. Repeat this process to completely remove the chaff impurities and granular impurities in the grain, and improve the screening efficiency.

Description

[0001] machine technology [0002] The invention relates to the technical field of industrial grain screening and impurity removal, in particular to a small vibrating grain hulling machine. Background technique [0003] After the drying process of the grain, the grain husk of the outer layer of the grain needs to be dehulled; in the traditional husk processing process, due to the light weight and small size of the grain husk, it is easy to be mixed in the hulled grain; while the traditional During the dehusking process, the exhaust fan is elevated, and then the worker bends down to fill the hulled grains into the pan, straightens up and lifts the pan so that the pan is higher than the exhaust fan, and then pours the grains in the pan When these grains pass through the wind blown by the exhaust fan, the grain husks mixed in the grains can be blown away, so that the grains are separated from the grain husks; however, this traditional impurity removal device makes the labor inten...

[0003] After the drying process of the grain, the grain husk of the outer layer of the grain needs to be dehulled; in the traditional husk processing process, due to the light weight and small size of the grain husk, it is easy to be mixed in the hulled grain; while the traditional During the dehusking process, the exhaust fan is elevated, and then the worker bends down to fill the hulled grains into the pan, straightens up and lifts the pan so that the pan is higher than the exhaust fan, and then pours the grains in the pan When these grains pass through the wind blown by the exhaust fan, the grain husks mixed in the grains can be blown away, so that the grains are separated from the grain husks; however, this traditional impurity removal device makes the labor intensity of the workers very large; and, Workers can only screen the grain bucket by bucket, and cannot screen continuously, so the screening efficiency is also very low

[0004] In the Chinese patent with the patent number CN105499133A, a grain removal mechanism is disclosed, including a base, a hopper, a vertical channel, an inclined channel, a fan, a swing plate, a swing rod, a bracket and a transmission gear, and the bracket is fixedly connected On the base, and on the bracket, there is a storage bag for storing the grains after cleaning; although this mechanism can remove impurities in the grains, it cannot lift the grains repeatedly to completely remove the grain husks in the grains
