Grain particle sieving device

Abstract

The invention discloses a grain particle sieving device which includes a turntable and a screening box located above the turntable. A protruding wave slideway is arranged on the outer side surface ofthe turntable, a sliding block matched with the wave slideway is arranged inside the wave slideway, a piston matched with the inner wall of a cylinder is arranged inside a fixed cylinder, one side ofthe piston is fixedly connected with the sliding block through a connecting rod, air inlet holes and air outlet holes are formed in the upper end and the lower end of the fixed cylinder, and the air outlet holes communicate with the inner part of the screening box through air outlet pipes. The turntable can give a circumferential force to the screening box to complete sieving of grain, while the grain is sieved, dust of the grain can be removed through the arrangement of the wave slideway and the fixed cylinder as well as air inlet pipes and the air outlet pipes, and the functions are practical; and the screening function and the grain dust removing function can be realized by sharing one rotating motor for driving, and the structure is compact and simple.

Description

technical field [0001] The invention relates to the technical field of screening, in particular to a grain particle screening device. Background technique [0002] Grain refers to the general term for various plant seeds used as staple food in cooking food, and can also be generally referred to as "grain". Grains need to be sieved after harvesting and drying, and are divided into different particle grades for sale, and at the same time to remove dust and impurities contained in the grains, but currently the dust is more serious when sieving grains, if these dusts are not treated , It is easy to affect the health of the operator. [0003] The patent notification number is CN 206229624 U, which proposes an agricultural grain screening device for grain screening and dust removal, wherein the screening and dust removal are driven separately, and the structure is huge and complex. Contents of the invention [0004] The purpose of the present invention is to solve the shortcom...
