Grain automatic processing machine

Abstract

The invention provides an automatic grain processing machine which comprises a hoisting frame and a supporting frame; the lower portion of the hoisting frame is provided with fan covers, openings of the fan covers face downwards, end openings of the fan covers are provided with a breathable cloth layer, the fan covers are connected with a draught fan through an air pipe, and the draught fan is fixedly installed on the hoisting frame; the upper portion of the supporting frame is provided with a guide plate, one end of the guide plate is hinged to the supporting frame, the bottom of the guide plate is hinged to an air cylinder, and a cylinder body of the air cylinder is hinged to the bottom of the supporting frame; and the side portion of the supporting frame is provided with a material distribution box, the material distribution box is internally provided with a plurality of inclined partition plates, the partition plates are parallel to one another, and a lateral opening of the material distribution box faces the supporting frame. A single impurity similar to a grain in size is mostly different from the single grain in weight, and the impurities and the grains are separated through the difference of properties of the impurities and the grains; and high-quality refined separation is performed on the grains preliminarily processed, the impurities which are similar to the grains in size but different from the grains in weight can be separated from the grains, quality of the grains is optimized, and the number of the impurities is lowered.

Description

technical field [0001] The invention belongs to the field of grain engineering, in particular to an automatic grain processing machine. Background technique [0002] Granular grains are mixed with stones, debris, gravel, bran and other sundries after preliminary treatment, which requires grain processing to remove the sundries. At present, the processing is mostly carried out by sieving, which is only separated by particle size, and it is difficult to screen out impurities whose particle size and volume are close to the grain itself. Contents of the invention [0003] The invention provides an automatic grain processing machine to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] The automatic grain processing machine includes a hoisting frame and a supporting frame. The lower part of the hoisting frame is equipped with a windshield, the opening of the windshield faces downward, and a breath...
