Pneumatic precision seeder

Abstract

The invention discloses a pneumatic precision seeder which comprises a main machine frame, a front fork combination, a rear wheel combination, a seed discharging device, a power device, a pneumatic device and a furrowing device. The pneumatic precision seeder is compact in structure, multifunctional and high in seeding efficiency, and can work stably, fine seeds can be effectively sown, the phenomena of repeated seeding, seeding omission and seed damage can be prevented, and the production cost and the labor cost are greatly reduced.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a pneumatic precision seeder. Background technique [0002] With the development of social economy and the improvement of the degree of mechanization, more and more agricultural machinery has been used to liberate farmers from heavy physical labor, and the work efficiency has been greatly improved. [0003] At present, most of the seeders in the domestic market use the external grooved wheel as the core component, and there is a phenomenon of uneven sowing. When sowing small seeds below 3 mm, the single seed sowing effect is poor, and there are re-seeding, missed seeding, and seed damage. , Unstable seeding rate, imprecise and other problems, while causing a lot of workload for post-sowing work, it leads to a lot of waste of seeds, and even causes a lot of crop production reduction. Moreover, the seeding machine does not work smoothly, has many faults, cannot complete joint...

Problems solved by technology

[0003] At present, most of the seeders in the domestic market have external grooved wheels as the core components, and there is a phenomenon of uneven sowing, but the single-seed sowing effect is poor when sowing small seeds below 3 mm, and there are re-seeding, missed seeding, and seed damage. , Unstable seeding amount, imprecise and other problems, which caused a lot of workload for the post-sowing work, at the same time, led to a lot of waste of seeds, and even caused a large amount of crop production reduction

Moreover, the seeding machine does not work smoothly, has many faults, cannot complete the joint operation, and the operation efficiency of the whole machine is low
