Precision seeder

Abstract

The invention provides a precision seeder which comprises a stand and a seeding mechanism arranged on the stand, wherein the seeding mechanism comprises a seeding bracket, a seed box and a seeding wheel; the seeding wheel comprises an outer wheel body and an inner machine body; seed discharging ports are uniformly formed in the outer side circumferential surface of the outer wheel body; a seed catching slot is formed in the inner side circumference; one side of the seed catching slot is provided with a spiral-shaped seed storage box communicated with the seed discharging ports; a plurality ofcams are arranged in the center of the outer wheel body; driving wheels matched with the cams are arranged on the inner machine body; a plurality of seed vortexes are arranged on the circumference ofa seed discharging wheel on the inner machine body; each seed vortex only accommodates one seed. According to the precision seeder, the seed discharging wheel provided with the seed vortexes and a brush are arranged on the inner machine body, and the spiral-shaped seed storage box is arranged on the outer wheel body, so that when the cams and the driving wheels are matched, one seed is precisely seeded via the spiral-shaped seed storage box through the seed discharging ports; the phenomenon of ridge breakage during seeding of the existing seeder is avoided; waste of seeds is reduced; the unnecessary economical loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a precision seeder. Background technique [0002] my country is a large traditional agricultural country. There is severe water shortage and drought in the north of our country. Grain planting is the pillar industry of farmers. The government regards the development of agricultural production as the primary task of increasing farmers' income, and adopts various measures to promote the transformation of traditional agriculture to modernization. In order to speed up the pace of developing agriculture through science and technology, new products, new technologies and new models are applied. [0003] At present, the commonly used seeder has a ditching body structure, and the seeder adopts a metal seed spoon structure, which leads to disadvantages during sowing. The metal seed plate is easy to break the seeds. At the same time, it is generally used to return straw to the...

Problems solved by technology

[0003] At present, the commonly used seeder has a ditching body structure, and the seeder adopts a metal seed spoon structure, which leads to disadvantages during sowing. The metal seed plate is easy to break the seeds. At the same time, it is generally used to return straw to the field. Sometimes weeds and residual film will entangle the opener, affecting the quality of sowing, reducing the emergence rate, resulting in uneven sowing, resulting in ridge breakage, the need to replenish seedlings, or even destroying plowing for reseeding, resulting in waste of seeds and unnecessary economic losses
