Automatic grain selecting and sorting machine

Abstract

The invention discloses an automatic grain selecting and sorting machine. The machine comprises a frame body, a funnel, a drag bucket, a rotating body, a maple leaf wheel, a walking wheel, a screen body, a garden bucket, an impurity groove, an arc-shaped channel, a screw, a motor, a switch, a triangular belt, a motor wheel, a rotating wheel, a shaft, a long shaft, a shell, a shaft wheel, a spannerand the like; multi-layer partition beams are arranged on the frame body, a square opening for inserting a funnel is formed in the upper layer, and the screen body is formed through the screen connected with two opposite round frames; and the spiral body is formed by two discs connected with two groups of opposite cross beams. The machine is suitable for grain seed cereals such as wheat, rice, soybeans, corns, sorghum, mung beans, red beans, peanuts and rape seeds to be screened, long-term storage is facilitated, the cereals are not easy to go mouldy and go bad, and the machine is an ideal instrument which is indispensable for agriculture; and the machine is safe and reliable, is low in cost, is long in service life, is convenient and rapid, is low in power consumption, is low in noise, is labor-saving, is huge in market, is durable in use and stable in performance, and accords with the mechanical principle.

Description

Technical field: [0001] The invention relates to a grain selection machine, in particular to an automatic grain selection and grading machine. Background technique: [0002] At present, there are three main types of grain filter used in domestic and foreign markets: the first type is manual screening, which uses a sieve to filter out super-large impurities; the second type is a draft type grain selection machine, which is mainly used to clean light-weight straw branches and leaves in grain types Restore skin impurities; the third is to have a square two-layer frame, the upper layer is a fixed screen, which is used to filter out impurities such as straw branches and leaves that are larger than grain seeds, and the lower screen is fixed to the square frame. There is an upward rocker arm on the frame, and the upper part of the rocker arm is installed on the corresponding beams on both sides of the lower layer of the square two-story frame. The motor is installed on one end of t...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of the above-mentioned known grain seed screening machine. The efficiency of screening grain seeds is low, the dust removal is not thorough, and the equipment is simple, which leads to the fact that the grain selection cannot automatically form a graded flow, and there are insufficient sand, dust, straw, branch and leaf impurities. Thoroughly, it is easy to cause mildew and deterioration of grain seeds, which will cause certain economic losses to grain farmers and affect agricultural development. In order to ensure automatic grading of selected grain types, thoroughly clean up impurities in grain types, better long-term storage of grain types, and better development agricultural problems; and provide an automatic grading machine for grain selection that can overcome the above-mentioned shortcomings
