Description

Cable disc fluid seeder

technical field

The invention belongs to the technical field of agricultural machinery, in particular to a cable-drum type fluid sowing and metering device.

Background technique

Most of the existing sowing machines are dry seeds, and there is a seed outlet in the lower part of the seed box, and the seeds are sown by controlling the amount of seed discharge. This method of sowing is not conducive to seed germination and growth during the dry season in spring. Fluid seeding uses the water-retaining agent to release water slowly when the environment is short of water and absorb water when the environment is rich in water, so as to ensure the water requirements for seed germination and growth. The invention patent with the patent application number CN201410467669.1 discloses a liquid seeder, which includes a seed box. A piston mechanism is arranged between the seed tubes, a one-way valve is arranged between the seed tube and the piston mechanism, a dripper is arranged at the end of the seed introduction tube, and a seed paper is arranged under the dripper. Through the movement of the piston mechanism and the opening and closing of the one-way valve, the seed liquid is dripped onto the seed paper through the dripper, and the seed paper is driven forward by the roller for sowing. Although it realizes liquid sowing, it is easy to get stuck when sowing through piston movement and dripper, which affects the sowing effect.
