Seeding tray structure assembly and seeding device

Abstract

The invention discloses a seeding tray structure assembly. The seeding tray structure assembly comprises an outer seeding tray, a fixed tray and a seeding sieve, wherein the outer seeding tray, the fixed tray and a shaft hole of the seeding sieve are located in a same axis, the fixed tray is embedded in the outer seeding tray, a seed discharging hole is formed in the side wall of the fixed tray, the seeding sieve is placed in the fixed tray, the upper end of the fixed tray is fixedly connected with a cover plate, the outer side of the outer seeding tray comprises multiple arc-shaped clamping plates which are fixed through clamping and define a disc shape, seed leaking holes and punching heads next to the seed leaking holes are formed in the arc-shaped clamping plates, seed guide pipes communicating with the multiple seed leaking holes in a one-to-one correspondence manner are arranged in the outer seeding tray, and a seed feeding hole is formed in the cover plate. Compared with a traditional seeding device, the device facilitates multigroup and large operation, is particularly suitable for large-area operation, and is closer to use reality and suitable for promotion and use.

Description

technical field [0001] The invention relates to a sowing device, in particular to a sowing disc structural component and a sowing device. Background technique [0002] With the advancement of science and technology and the increase of human capital, mechanized planting has become the mainstream trend. Not only is it not as simple as manpower, it takes less time, but also because mechanized farming is more scientific, and the spacing of sowing is more uniform, the depth is also consistent, and the distance between plants The row spacing is relatively stable, the soil is well covered, the efficacy is high, and most importantly, seeds are also saved. Many advantages have already ensured that the crops grow into seedlings; at the same time, it is conducive to saving labor, and can ensure crop planting, care and harvesting, etc. The link does not miss the farming time, which is beneficial to reduce the loss of crops; farm mechanization can save manpower, material resources and fi...

AI Technical Summary

Problems solved by technology

[0004] (1) Different sowing structures need to be manufactured for different crops. The planting adaptability of the seeder is poor, and it cannot be simply replaced. For example, the seeder for planting peanuts is used to remove vegetable seeds. This problem leads to an increase in the cost of mechanized equipment and a variety of crops. Growth had to be equipped with different seeders;

[0005] (2) For film-covered cultivation, it is necessary to manually break the film and release the seedlings, otherwise the phenomenon of high-temperature scalding will occur, which greatly increases the labor force;

[0006] (3) The internal structure of the existing seeder is easy to damage the seeds, resulting in high damage rate, which cannot meet the requirements of farmers for sowing;

[0007] (4) The precision sowing effect of the existing seeders is poor, and it is difficult to achieve one-by-one. Most of them are continuous linear or continuous planar, and different crops have different growth environment requirements, which affects crop production capacity;

[0008] (5) There is a seed passage in the duckbill-type punching head on the market, and grass and mud are caught during the seed spit process of duckbills opening and closing, which affects the quality of sowing;

[0009] (6) As long as the plant spacing of the existing seeder is set, it cannot be adjusted, and the adaptability to different varieties is poor;
