Automatic grading machine for removing impurities in grain seeds

Abstract

The invention discloses an automatic grading machine for removing impurities in grain seeds. The automatic grading machine comprises a machine body, a rotary body, a rotary body shaft, an opened sleeve, a screen, a maple leaf wheel, a shaft wheel, a rectangular belt, an electric motor, a motor wheel, a grading box, a funnel, a door, an impurity barrel, a rotary wheel, a threaded rod, a puling handle, a shell, a small shaft, walking wheels, a universal rack and the like; the rotary body is provided with a shaft hole, and the part, which penetrates through the shaft hole, of the rotary body shaft is provided with the maple leaf wheel and the shaft wheel; the rotary shaft penetrates through a corresponding shaft hole formed in the machine body to be assembled; the automatic grading machine isapplicable to one-step screening, impurity removing and grading of wheat, rice, beans, corns, broomcorn, mung beans, peanuts, rapeseeds and other particle seeds, dried fruits and grains; cleanness isgood; long-term storage is facilitated; molding and deterioration do not happen easily; and the automatic grading machine is an indispensable ideal device for agriculture, and is safe, reliable, lowin cost, long in service life, convenient, rapid, low in power consumption, low in noise, labor-saving, large in market, durable, stable in performance and accordant with mechanical principle.

Description

Technical field: [0001] The invention relates to a grain seed machine, in particular to an automatic grading machine for removing impurities in grain seeds. Background technique: [0002] my country is a large agricultural country, and it is also a populous country. The country has a large amount of grain storage every year, which is divided into soybeans, wheat, rice, corn and other grains stored in the grain depots directly under the grain depots and local grain depots. The purchase price is determined by the proportion of impurities. After the purchase and storage, it is directly put into the storage after simple drying. Why do thousands of tons of various grains go moldy every year, causing certain economic losses to the country? The reason is that the purchase and storage of grain has not been carried out Secondary cleaning of impurities, drying and grading. The grains of each grade have the same particle size and are dried to completely remove moisture and impurities. Th...

Problems solved by technology

[0004] The disadvantages of the above-mentioned grain selection equipment are: firstly, the efficiency is low, the cleaning of impurities in grain selection is not thorough, and the particles of grain seeds are smaller than the sieve holes, and the superior grain types are mixed with impurities, which reduces the income as other uses; the second is that the grain selection process can only be cleaned Impurities such as light straw, branches and leaves in the grain seeds cannot be thoroughly cleaned of other impurities in the grain seeds, and the grain seeds are prone to mildew and deterioration; the third is to screen out the oversized impurities in the grain selection process to select the grain seeds, and the grain and impurities smaller than the sieve hole Mixing is not convenient for long-term storage
