Two-degree-of-freedom adjustment vibrating sucker type precision sowing device

Abstract

The invention discloses a two-degree-of-freedom adjustment vibrating sucker type precision sowing device. The two-degree-of-freedom adjustment vibrating sucker type precision sowing device comprises astand, a seed adding device, a controller, a seed tray device, a seed sucking device and a seedling tray driving device, wherein by use of the seed adding device, seeds can be uniformly, continuouslyand precisely added into the seed tray device; the seed tray device adopts two-degree-of-freedom adjustment; the angle of a seed tray can be adjusted by using a driving mode of lead screw and screw nut and gear and rack; the seed tray device is suitable for different sowing environments; the seeds are violently shaken by adopting vibration, and further a frictional force among the seeds can be reduced; the seed sucking device provides power for sucking the seeds by adopting an air pump; a sensor can be used for sensing whether the seeds are sucked to single suction nozzle of the seeds or not;if the seed suction rate does not reach the requirements, the seed sucking tray stays for a longer time and the missing sowing rate is reduced; after seed suction is finished, the seed sucking tray moves to the seedling tray driving device for sowing. The two-degree-of-freedom adjustment vibrating sucker type precision sowing device disclosed by the invention has the advantages of reliable work,diversified functions, convenience in maintenance, high sowing efficiency, no damage to the seeds, low missing sowing rate, high degree of automation and the like.

Description

technical field [0001] The invention belongs to the technical field of precision seeding, in particular to a two-degree-of-freedom adjustable vibration sucker type precision seeding device. Background technique [0002] my country is a large agricultural country, and the degree of mechanization of agricultural production is relatively backward, which greatly restricts the improvement of agricultural labor productivity. With the continuous development of science and technology, agricultural mechanization has become a trend, and high-efficiency precision seeding plays a very important role in promoting agricultural production. [0003] At present, the existing precision seeders on the market have deficiencies in sowing precision, sowing efficiency, and seed protection. For the existing air suction seeding equipment, the angle of the seeding disc of the existing seeder often cannot be adjusted automatically, or only a single degree of freedom can be adjusted, so it is easy to ...

AI Technical Summary

Problems solved by technology

For the existing air suction seeding equipment, the angle of the seeding disc of the existing seeder often cannot be adjusted automatically, or only a single degree of freedom can be adjusted, so it is easy to be restricted by various terrain factors when sowing, which affects the sowing efficiency ; Seed discs are often stationary, which greatly affects the efficiency of seed suction
