Description

Technical Field

[0001] The invention belongs to the technical field of seed drills, and in particular relates to a rotary tillage, ridging and film covering electric precision seed drill for wheat and pepper interplanting. Background Art

[0002] In recent years, the intercropping pattern of wheat and pepper in winter wheat areas has developed rapidly, but the machinery and equipment suitable for the agronomy of wheat and pepper intercropping has just started. The integrated machinery of rotary tillage, ridge making, mulching and sowing suitable for the agronomy of wheat and pepper intercropping has become a new research direction, especially the precision seeding and planting technology.

[0003] The existing rotary tillage, ridging and film-covering seeders on the market are mainly mechanical hole seeders. When sowing peppers, there are 1 to 5 seeds per hole. In the late sowing period, there are serious problems with seedling shortages and multiple plants in one hole. Manual seedling thinning and refilling are labor-intensive and costly. There are a small number of mechanical air-suction precision seeders on the market, but because the mechanical fan is driven by the tractor PTO and the output speed of the tractor PTO is unstable, although the number of pepper seed holes is improved compared to the mechanical hole seeder, manual thinning and refilling are still required, especially in the field head area, where the engine speed drops, the fan wind pressure is insufficient, and there is a serious shortage of seeds at the field head, requiring a large amount of manual seedling refilling work.

[0004] The invention patent "A Chili Ridge Film Covering Seeder" published by the State Intellectual Property Office on January 6, 2023, has the authorization announcement number CN218218207U. The patent describes that a ridging plow is used for ridge formation, and the motor drives the transmission roller to rotate to break the soil clods scooped up by the ridging plow. A protective plate is installed on the rear side of the transmission roller to protect the sowing tube and film covering devices. The sowing bucket sows the seeds into the seed bed through the sowing tube, and the ground film covers the ridge-shaped seed bed after sowing. The ground wheel and the film pressing plow cooperate to cover the soil on both sides of the ground film. The invention uses a ridging shovel to form ridges, which mainly solves the problem of breaking the soil clods turned over by the ridging shovel, but does not solve the problem of precision sowing.
