A kind of winnowing machine and winnowing method thereof

Abstract

The invention discloses a winnowing machine and a winnowing method thereof and belongs to the field of crop seed impurity removal machinery. The winnowing machine comprises a draught fan and an impurity collection box and further comprises a winnowing component, a feeding hopper and a discharging hopper, wherein the winnowing component is arranged below the feeding hopper; the discharging hopper is located below the winnowing component; the draught fan is located at the left side of the winnowing component; and the impurity collection box is located at the right side of the winnowing component. The winnowing machine further comprises flying dust adsorption equipment. The flying dust adsorption equipment comprises an upper air opening, a flying dust filter bag and a flying dust collection hopper in sequence from top to bottom. The impurity collection box comprises filter plates, a heavy impurity hopper, a light impurity hopper and a flying dust outlet. The winnowing component is arranged at the left side of the upper portion of the impurity collection box. The upper portion of the impurity collection box is formed by combining the filter plates. The heavy impurity hopper and the light impurity hopper are arranged on the lower portion of the impurity collection box in sequence from left to right. The flying dust outlet is formed in the right side of the upper portion of the impurity collection box. The flying dust outlet communicates with the flying dust adsorption equipment. By means of the winnowing machine, impurities in grains can be removed; mildewed or imperfect seeds are separated from good seeds which are plump in grain; and the seeds can be stored conveniently and sold and processed conveniently at the later stage.

Description

technical field [0001] The invention relates to the field of machinery for removing impurities from crop seeds, in particular to a winnowing machine and a winnowing method thereof. Background technique [0002] When traditional crop seeds are harvested, impurities such as chaff, chaff, dust, and soil in the grain will be removed by manual operation or high-altitude throwing, and the wind will blow away the chaff and soil in the grain. It is difficult to remove impurities such as heavy stones that exist in the grain drying process, and the manual operation is labor intensive, high in cost, and low in work efficiency. [0003] With the development of agricultural automation, automated combine harvesters have replaced the previous manual operation of harvesting crops. After the crop seeds mature, they are harvested at one time by a grain combine harvester, and there are no heavy stones in the harvested grains. However, there will still be lighter impurities such as unremoved c...

AI Technical Summary

Problems solved by technology

Its shortcoming is that this patent is used to solve the separation of impurities such as heavy stones and seeds, and the deflector provided in this technical solution forms a plurality of exhaust outlets in the exhaust air duct, so as to form a whirlwind , using the principle of cyclone suction to separate the heavy stones and other impurities in the seeds from the seeds, and cannot remove the lighter impurities of the seeds, as well as the mildewed and unfulfilled seeds
