An air sieve type seed selection machine

Abstract

The invention discloses an air sieve type seed concentrator in the technical field of seed concentrators, comprising a casing, the bottom of the casing is provided with a shock-absorbing structure, and the inner wall of the casing is provided with a sound-absorbing structure. There are speed control baffles and settling chambers on the left and right sides of the top of the inner cavity of the shell, springs are installed in the four sets of installation cavities, coarse grain screen boxes are installed on the top of the two sets of springs on the top, and coarse grain screen boxes are installed on the top of the two sets of springs at the bottom. The top of the spring is equipped with a fine-grained screen box, the bottom of the coarse-grained screen box and the fine-grained screen box are equipped with a vibrator, the bottom of the inner cavity of the housing is installed with a deflector, and the left side of the fan An air pipe is connected, and the other end of the air pipe is connected with a nozzle, the nozzle is located on the left top of the speed control baffle, and the left bottom of the housing is provided with a second discharge port. The invention has a simple structure. It is easy to use, can remove debris well, can screen and classify seeds well, and has high efficiency.

Description

technical field [0001] The invention relates to the technical field of seed selection machines, in particular to an air sieve type seed selection machine. Background technique [0002] The air sieve type seed sorting machine is the main equipment for seed and grain processing. It mainly uses the sieve to remove the heavy or large impurities in the seeds and grains, and uses the fan to remove the light impurities or diseased seeds from the good seeds. At present, the air sieve type seed sorting machines at home and abroad are all mechanical, and the operation process depends on experienced technical manual operation and adjustment, which cannot perform good screening and classification of seeds. The existing air sieve type seed sorting machine has a complex structure, is very cumbersome to operate and not finely controlled, and cannot perform good sorting on seeds, which seriously affects the quality of seed sorting, and the efficiency of seed sorting is low and wasteful Big...

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of wind screen type seed sorting machine, to solve the problem that the existing wind screen type seed sorting machine proposed in the above-mentioned background technology has complex structure, very cumbersome operation and imprecise control, and it is impossible to process seeds. Very good selection seriously affects the selection quality of seeds, and the selection efficiency of seeds is low and the waste is large
