Abstract

The invention discloses a separation and connection type land wheel of a pneumatic sower and a transmission device of the land wheel, and belongs to the technical field of pneumatic sowers. The land wheel aims at solving the problems that the design of an existing land wheel transmission device is not reasonable, the sowing distance is not accurate, and seeds are wasted in the process of row-changing sowing. The land wheel comprises a land wheel supporting arm plate, a seed discharging device power transmission assembly, a land wheel transmission assembly, an upper chain wheel, a lower chain wheel, chains and a land wheel body, an installing hole of the seed discharging device power transmission assembly and an installing hole of the land wheel transmission assembly are respectively processed in a land wheel supporting arm plate body, and the seed discharging device power transmission assembly and the land wheel transmission assembly are installed on the land wheel supporting arm plate; the upper chain wheel is installed on the seed discharging device power transmission assembly, the lower chain wheel is installed on the land wheel transmission assembly, the upper chain wheel and the lower chain wheel are installed through the chains, and the land wheel body is installed on the land wheel transmission assembly. By selecting a corresponding transmission mode, the accurate transmission ratio is designed and calculated, it is ensured that the plant distance is consistent, the waste of seeds is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a ground wheel transmission mechanism of a seeder, belonging to the technical field of pneumatic seeders. Background technique [0002] The use of the pneumatic small seed precision seeder is an important part of the mechanization of the vegetable planting industry, and it is also a key operating tool in vegetable planting. The purpose of its use is to accurately and reasonably sow vegetable seeds into the soil according to the corresponding sowing technical requirements in a reasonable sowing season according to the vegetable planting requirements. [0003] Among them, there is an important relationship between the seeding quality of the pneumatic small-grain seed precision seeder and the seeding device, and will also have a corresponding impact on crop yield. It can achieve precise seeding, ensure a certain seedling spacing and planting depth, and lay a solid foundation for the growth of vegetable seedlings. A certain founda...
