Seeding disc structure assembly and seeding device

Abstract

The invention discloses a seeding disc structure assembly, which comprises an outer seeding disc, a fixing disc and an inner seeding disc, wherein shaft holes of the outer seeding disc, the fixing disc and the inner seeding disc are on the same axis; the fixing disc is arranged in the outer seeding disc in an embedded manner; the inner seeding disc is arranged in the fixing disc; a cover plate isarranged at the upper end of the inner seeding disc; the cover plate is arranged on the fixing disc and is fixedly connected with the fixing disc; the outer side of the outer seeding disc comprises aplurality of groups of presser foot units consisting of seed leakage holes and hole punchers which are close to the seed leakage holes; two presser foot units are fixedly connected; seed guide pipes corresponding to and communicated with a plurality of the seed leakage holes are arranged in the outer sowing disc; a seed inlet hole is formed in the cover plate; and a seed metering advance angle isarranged on the side surface of the fixing disc. Compared with a traditional seeding device, the device is beneficial to multi-grouping, large-scale, especially suitable for large-area loading, more suitable for practical use, and suitable for popularization 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 hole puncher 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;
