Precise uniform seed adding device of precision seeder

Abstract

The invention discloses a precise uniform seed adding device of a precision seeder, and belongs to the field of seeders. The precise uniform seed adding device comprises a material box, a distributor,discharge pipes and distribution bins, wherein the distributor is mounted on one side of the material box, a plurality of distribution bins are uniformly arranged in the distributor, the discharge pipes are mounted on the lower side of the distributor and corresponds to the distribution bins, a feeding mechanism is arranged in the material box and comprises a feeding pipe, the feeding pipe is fixed to the inner wall of the side, close to the distributor, of the material box, a spiral blade lifting rod is rotationally installed in the feeding pipe, a plurality of discharging openings are formed in the side, close to the distributor, of the feeding pipe and the side, close to the distributor, of the material box in a penetrating mode, and the discharging openings are in one-to-one correspondence with the distribution bins. According to the scheme, through the arrangement of all the structures, continuous feeding of seeds in the material box can be achieved, meanwhile, the discharging amount of the discharging openings can be adjusted, and in addition, seed waste can be avoided.

Description

technical field [0001] The invention relates to the technical field of seeders, in particular to a precise and even seeding device for a precision seeder. Background technique [0002] With the continuous development of seeding technology, the advantages and disadvantages of seeding technology reflect the overall technical level of agricultural mechanization in a country, and the seeder is the core component of agricultural mechanization. In order to realize the high-efficiency continuous precision sowing of the seeder, it is necessary to carry out precise and uniform reseeding of the seeder. [0003] After retrieval, Chinese Patent No. CN 105474844 B discloses a precise and uniform seeding device for a precision seeder, which mainly relates to the technical field of agricultural precision seeders. It consists of a frame, a control device, a transmission device, a seed adding box, a seed transport device and a seed guide plate. Control device is positioned at the left end ...

AI Technical Summary

Problems solved by technology

[0004] The seeding device in the prior art still has the following disadvantages in actual use: such a device is provided in the seeding box of the seeding device, and this method of the device cannot achieve continuous and accurate continuous seeding. That is to say, there are intermittent seeding operations, and the efficiency needs to be improved; in addition, the amount of seeds cannot be accurately adjusted when adding seeds, which is likely to cause waste of seeds and over-planting. Therefore, a precision and uniform seeding device for precision seeders is proposed again
