Air-suction type anti-leakage sowing device

Abstract

The invention discloses an air-suction type anti-leakage sowing device, which belongs to the field of agricultural machinery. The lower end of a shell is provided with a seed discharging hole; a seeddischarging disk and a seed stirring rod are installed in the inner cavity of the shell and are in parallel with the outer plane of the shell; through a supporting rod and a bearing support, a servo motor is connected to realize rotation; two sides of the seed discharging disk are independently provided with a negative pressure cavity and a positive pressure cavity, and seeds are adsorbed througha pressure difference; a hole plugging block and a seed plugging block are independently positioned on two sides of the seed discharging disk; and the hole plugging block is fixedly connected to the shell, and the seed plugging block is driven through a stepping motor to rotate through the bearing support so as to jointly act to realize the falling of seeds. The air-suction type anti-leakage sowing device is suitable for spherical and elliptic seeds and can effectively sow and lower a sowing missing rate to enable a sowing state to be even.

Description

Technical field [0001] The invention belongs to the field of agricultural machinery, and relates to a seeding device, in particular to an air suction type leak-proof seeding device. Background technique [0002] In the modern seeding process, there are three problems in the seeding process. First, the seeder is not applicable and has poor adaptability; second, the manufacturing cost is high, which does not meet the low-cost green development trend; third, the seeding is unstable, easy to miss, and more efficient. Low, is not conducive to modern agricultural mechanized planting operations. The structure of the seeder has an important influence on the quality of seeding and is beneficial to improve the quality of crop production. Modern seeding devices are mainly composed of outer groove wheel seeders, drum seeders and air suction seeders. The complex structure, unstable operation, poor adaptability to seeds and other reasons will cause uneven seeding and missed seeding. Therefore...

Problems solved by technology

[0003] The purpose of the present invention is to propose a kind of air-suction leak-proof seeding device, which is simple in structure and easy to use, in view of the shortcomings of existing sowing devices such as poor adaptability, high manufacturing cost and low efficiency and poor fertilization effect caused by missed sowing. It can achieve stable sowing, prevent missing sowing, and can also achieve low-cost manufacturing machinery and improve operating efficiency.
