Description

The adjustable Pneumatic precision seed sowing device of one kind amount of broadcasting
Technical field:
The present invention relates to agricultural seeder technical field, the adjustable Pneumatic precision seed sowing device of one kind amount of broadcasting is related generally to.
Background technology:
Essence amount cave direct seeding technique can by crop plantation agriculture requirement, by seed by the spacing in the rows needed for it, line-spacing and seed number per want It is distributed in field the quasi- cavitation of refinement, required grain weight during sowing can be saved, reduces the thinning operation of later stage field management, and energy Make that seedling is neat, Miao Yun, Miao Zhuan, be that rational field plant group structure is created in the growth of later stage crop, increase production beneficial to stable yields, exist It is used widely in the sowing field of the bunch planting crop such as paddy rice, corn and soybean, cotton.
The core work part of mechanization essence amount cave direct seeding technique is precise seeder, current main using mechanical gentle Two kinds of seeding principles of power formula come realize bunch planting operation essence amount seeding.Pneumatic type seeding principle is to crop seed shape and size Adaptability is stronger, does not cause damage substantially to seed, the Main Means as the essence amount seeding of bunch planting crop.
It is same kind, different soils and weather conditions, per cave because Different Crop kind is different per cave Seeding Quantity Application rate equally exists difference, and this requires that precise seeder can require to adjust its actual bunch planting amount according to reality sowing.It is existing Pneumatic seeding apparatus mainly adjusts application rate, disassembling, assembling and replacing mistake by changing the air-suction parts of different sucker shapes or sucker number Journey is relatively complicated, and being dismounted for multiple times can influence the air-tightness of Pneumatic seeding apparatus, influences feed mechanism for seed seed-metering performance.
The content of the invention:
The object of the invention be exactly in order to make up the defect of prior art there is provided the adjustable Pneumatic precision seed sowing device of one kind amount of broadcasting, Realize regulation of the feed mechanism for seed per bunch planting amount, without changing air-suction parts, while avoid air-suction parts being dismounted for multiple times and shadow The air-tightness of Pneumatic seeding apparatus is rung, and the regulation process of regulation detent mechanism is easy, is conducive to the lifting of operating efficiency.
