Mechanical dust removal device capable of separating out impurities conveniently for seed processing

Abstract

The invention relates to the technical field of agricultural machines, in particular to a mechanical dust removal device capable of separating out impurities conveniently for seed processing. The mechanical dust removal device comprises a bottom plate, a shell is arranged at the upper end of the bottom plate, an air suction fan, a first motor and a feeding pipe are arranged at the upper end of theshell, the upper end of a dust discharge port is provided with a screen net matched with an inclined wheel, a long rod matched with a cam is inserted to the upper end of a second transverse plate, and multiple baffles matched with fan blades are connected to the side wall of the long rod through rotating shafts. Small-grain dust can be sucked away and discharged through the arranged air suction fan, large-grain dust is vibrated to be broken since the baffles which are constantly vibrated and the fan blades which are rotated are arranged, filtration and discharge are carried out through the screen net and the dust discharge port, the removing effect on large-grain dust is improved, and the baffles can limit the falling speed of seeds to prevent seeds and dust from falling down directly. Compared with the prior art, the dust removal effect is more thorough and comprehensive, and practicability is high.

Description

Technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a mechanical dust removal device for seed processing which is convenient for separating impurities. Background technique [0002] When crop seeds are harvested, a large amount of dust, soil and other impurities will be attached. In order to improve the quality of seeds, these impurities need to be separated from the seeds before the initial processing of the seeds. The existing methods for removing dust from the initial processing of seeds generally use manual operations. The method of dust removal is carried out or thrown off at a high altitude. The manual operation is labor-intensive, high-cost, and low-efficiency. [0003] For a seed mechanical dust removal device described in patent CN203917281U, a plurality of inclined baffles are set in the body to remove the dust from the top and then use a fan to vacuum. Although it has a certain dust removal ability, the seeds fa...

Problems solved by technology

[0002] When crop seeds are harvested, there will be a lot of dust, soil and other impurities. In order to improve the quality of the seeds, these impurities need to be separated from the seeds before the initial processing of the seeds. However, the existing method of dust removal for the initial processing of seeds generally adopts manual operation. or high-altitude throwing dust removal method, manual operation is labor-intensive, high-cost, and low-efficiency

[0003] For a kind of mechanical dust removal device for seeds described in the patent CN203917281U, a plurality of inclined baffles are arranged in the body to remove dust from the top and then use a fan to suck dust. Although it has a certain dust removal ability, the falling speed of the seeds is relatively fast. The dust on the seeds is very likely to fall together with the seeds, and the number of times the seeds are vibrated to remove dust is not enough, and the large particles of dust may not be removed, resulting in the problem of poor dust removal effect. For this reason, we propose a method that is convenient for separating impurities. Mechanical dust removal device for seed processing
