Seed purifying device used for minimum seeds

Abstract

The invention discloses a seed purifying device used for minimum seeds. The device comprises a box body, multiple first screen holes are formed in a first screen plate detachably mounted on the upperend of the box body, two vibration screen plates with adjustable angles are symmetrically mounted in the box body, multiple second flat vibration motors are mounted on the lower surfaces of the innerends of the vibration screen plates, two second screen plates which are downwards inclined from outside to inside are symmetrically mounted at the positions, on the lower ends of the vibration screenplates, in the box body, multiple second screen holes are formed in the middles of the second screen plates, compared with the prior art, the device has the beneficial effects that the seeds and impurities pass through the first screen plate to be primarily screened, the screened seeds and the screened impurities can roll to the vibration screen plates, through work of the second flat vibration motors, the vibration screen plates can be driven to vibrate, the seeds can slide off from the vibration screen plates prior to the impurities, separation of the seeds and the impurities can be achieved, and finally, through screening of the second screen plates, the seeds containing a small amount of impurities can be obtained.

Description

technical field [0001] The invention relates to the technical field of net seeding of very small grain seeds, in particular to a net seeding device for very small grain seeds. Background technique [0002] Seeds are the initial carrier of plant sexual reproduction, and are the basis and key to vegetation renewal and restoration. They occupy a very important position in plant ecology. Therefore, seeds have attracted much attention in agriculture, forestry, animal husbandry, biology, and ecology. The seeds are very important. Common net seeding methods include grain selection, screening, winnowing and water selection. The study found that the weight of plant seeds can vary widely, spanning more than 11 orders of magnitude, involving some extremely small seeds, which are difficult to obtain by the above methods, and even It is difficult to distinguish with the naked eye. Some of these extremely small-seeded plants have direct economic value, and some can play important ecolog...
