Seed screening device for agricultural production

Abstract

The invention belongs to the technical field of agricultural production, and particularly relates to a seed screening device for agricultural production. For solving the problem of poor seed screeningeffect in the prior art, the seed screening device comprises a box body, wherein a feeding hopper is fixed to one side of the outer wall of the top of the box body, inclined blowing pipes are fixed to the two ends of the box body and the outer walls of the two sides of the box body, the ends, close to the interior of the box body, of the blowing pipes incline upwards, blowing fans are fixed to the inner walls of the blowing pipes, exhaust pipes are fixed to the positions, located at the top of the blowing pipes, of the two ends of the box body and the outer walls of the two sides of the box body, and exhaust fans are fixed to the inner walls of the exhaust pipes. According to the seed screening device, dust in seeds is discharged from the exhaust pipes through the wind direction cooperation operation between the blowing pipes and the exhaust pipes, the rest seeds fall into an auxiliary box containing salt water, the seeds with insufficient plumpness float on the water surface and areled out from a drainage pipe, and therefore winnowing and water separation operation is completed in the box body simultaneously; the seed screening effect of the device is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a seed screening device for agricultural production. Background technique [0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. The labor objects of agriculture are living animals and plants, and the products obtained are animals and plants themselves. Agricultural production refers to the production activities of planting crops, including food, Production of crops such as cotton, oil, hemp, silk, tea, sugar, vegetables, tobacco, fruit, medicine, miscellaneous (referring to other economic crops, green manure crops, feed crops and other crops), and the growth and cultivation of plants in agricultural production often require When using seeds, it is generally necessary to screen the seeds before planting and production. [0003] When screening seeds in agricultural prod...

AI Technical Summary

Problems solved by technology

[0003] When screening seeds in agricultural production, air selection or water selection is generally used. However, seeds with insufficient grains often fall with qualified seeds during air selection. , there is no separation between dust and seeds that are not full enough, so the actual screening effect on seeds is poor
