Angle-adjustable pneumatic type vegetable planter

Abstract

The invention relates to agricultural machines, in particular to an angle-adjustable pneumatic type vegetable planter. The angle-adjustable pneumatic type vegetable planter comprises a machine frame and a plurality of seeding units, wherein a loosening device, a twisting soil breaking tooth and a ridging device are sequentially arranged at the front end of the machine frame, the loosening device is arranged at the most front end of the machine frame, each seeding unit comprises a seeding unit front wheel, a furrow opener, an earthing device, a press wheel, a seeding unit rear wheel and a seedsowing device assembly, and each furrow opener, each earthing device, each seed sowing device assembly and each press wheel are sequentially arranged between each seeding unit front wheel and the corresponding seeding unit rear wheel. By adopting a spiral airway seed stirring mode, seeds cannot be damaged, the germination rate of the seeds is improved, meanwhile, adjustment of the angle of the seed sowing device assembly is achieved, the gravity effect of the seeds on a seed sowing disc is reduced, the seeds are prevented from falling down in the sowing process, and accordingly sowing leakageis avoided.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an angle-adjustable pneumatic vegetable seeder. Background technique [0002] When the pneumatic vegetable seeder is working, the negative pressure generated by the high-speed fan is transmitted to the vacuum chamber of the seeding unit. When the seeding disc rotates, it absorbs seeds under the negative pressure of the vacuum chamber and rotates together with the seeding disc. After the seeds turn out of the vacuum chamber, they no longer bear the negative pressure, and fall into the ditch by their own weight or under the action of the seed scraper. Existing vegetable seeders generally adopt mechanical stirring and seeding prevention. During the mechanical seeding process, the seeds will be rubbed, which will cause greater damage to the seeds and reduce the germination rate of the seeds; in addition, the existing vegetable The seeding disc in the seeder is generally set in a vertical d...

AI Technical Summary

Problems solved by technology

Existing vegetable seeders generally adopt mechanical stirring and seeding prevention. During the mechanical seeding process, the seeds will be rubbed, which will cause greater damage to the seeds and reduce the germination rate of the seeds; in addition, the existing vegetable The seeding tray in the seeder is generally set in a vertical direction, and the angle is fixed. Due to the gravity effect of the seeds on the seeding tray, the seeds are easy to fall off during the sowing process, resulting in missed sowing.
