Description

Air-suction type precision corn no-tillage planter

Technical Field

The invention relates to the technical field of agricultural machinery, in particular to an air-aspiration type precision corn no-tillage planter.

Background

The air-suction seeder is a seeder which can realize precision seeding by sucking seeds by negative pressure, and compared with a mechanical seeder, the air-suction seeder has stronger technical performance. When the air-suction type seeder works, a negative pressure is generated by the high-speed fan and is transmitted to the vacuum chamber of the seed discharging monomer. When the seed plate rotates, the seeds are adsorbed under the negative pressure of the vacuum chamber and rotate along with the seed plate. When the seeds are transferred out of the vacuum chamber, the seeds are not subjected to negative pressure, and fall into the groove under the action of the seed scraper or the dead weight, the working quality of the seeds can be evaluated by the void fraction and the reseeding rate, and the main influencing factors comprise the vacuum degree, the shape of the suction hole, the size of the seeds, the structure and the adjustment of the seed scraper and the like.
