An automatic screening device for vegetable seeds

Abstract

The invention discloses an automatic vegetable seed screening device, which comprises a vibrating chamber, a main shaft, a cover plate, a blower, a first screen, a second screen, a valve, a base, a first slider and a vertical bar. The cover plate passes through The rotating shaft is connected to the top of the vibrating chamber, the blower is installed inside the vibrating chamber, the top of the valve is provided with a connecting rod, the bottom of the base is fixedly equipped with universal wheels, and the inside of the first slider A rotating block is provided, and the vertical rod is fixedly installed inside the base. In the vegetable seed automatic screening device, when the vegetable seeds are preliminarily screened, the motor drives the main shaft to rotate, thereby driving the auger shaft to unload the vegetable seeds, so that the auger shaft can make the unloading work easier during the unloading process. The speed slows down, and at the same time, the lower end of the auger shaft uses the blower to discharge the impurities through the dust outlet, which is convenient for sufficient preliminary screening of vegetable seeds and is conducive to subsequent subdivision work.

Description

technical field [0001] The invention relates to the technical field of vegetable seed screening, in particular to an automatic vegetable seed screening device. Background technique [0002] Vegetable seed automatic screening device refers to a device that sorts vegetable seeds after screening. Seed screening is very important in the process of vegetable planting. Seeds with large or small particles are not conducive to cultivation, and in the field of agricultural planting, In order to improve the germination rate of crops, it is necessary to filter out the shriveled seeds in the seeds before sowing and keep the plump and good seeds, so as to achieve the goal of improving the germination rate of planting, but the existing vegetable seed automatic screening device also has the following problems; [0003] 1. During the preliminary screening of vegetable seeds, it is necessary to remove the impurities contained in the vegetable seeds and the shriveled vegetable seeds. However,...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of automatic screening device for vegetable seeds, to solve the problem of removing impurities in vegetable seeds caused by cutting too fast when the screening devices on the market proposed by the above-mentioned background technology carry out preliminary screening of vegetable seeds Insufficient problem, and at the same time, there is the problem that the screening effect is not ideal when subdividing vegetable seeds, and the vegetable seeds are easy to stay in the sieve during feeding, which reduces the work efficiency
