Abstract

The invention discloses an agricultural seed screening device. The device comprises a screening pool, wherein an inverted 'V'-shaped partition plate is arranged in the screening pool to partition thescreening pool into a high quality seed area and a poor quality seed area, the top of the screening pool is provided with a feeding funnel, the feeding funnel is located above the high quality seed area, an air blower is also arranged on the screening pool, an air outlet of the air blower points at a discharging port of the feeding funnel, the blowing direction of the air blower faces the high quality seed area, the portion, located at the bottom of the high quality seed area, of the screening pool is provided with a high quality seed outlet, and the portion, located at the bottom of the poorquality seed area, of the screening pool is provided with a poor quality seed outlet. The agricultural seed screening device has the advantages that the structure is simple, most of poor quality seedscan be separated from high quality seeds through a wind blowing mode, the effect is good, and the precision is high; to-be-screen seeds can be screened through two modes of air blowing and water floating, the screening precision is high, and the damage to the seeds is small.

Description

technical field [0001] The invention relates to the technical field of screening equipment, in particular to an agricultural seed screening device. Background technique [0002] Seeds are the reproductive system of seed plants and play an important role in the continuation of species. [0003] Limited by the low degree of mechanization, the existing crop harvesting in my country still adopts extensive methods, the utilization rate of high-precision equipment is very low, and traditional manual methods are still used in many places. These methods are not only labor-intensive, but also Moreover, the obtained seeds are uneven, mainly manifested in the fact that there are too many impurities such as weeds and straw in the seeds, or they are shriveled, immature, and incomplete. If too many low-quality seeds are mixed with high-quality seeds, if they are not separated and removed in time, on the one hand, it will cause a lot of unnecessary labor, and on the other hand, it will als...
