Adjustable potato whole-film double-furrow seeder

Abstract

The invention discloses an adjustable potato whole-film double-furrow seeder. The seeder comprises a frame, walking land wheels are arranged below the rear end of the frame, a gearbox is arranged above the front end of the frame, the middle of the lower part of the front end of the frame is provided with a trenching wheel, a fertilizer box is arranged above the front part of the frame, the lower end of the fertilizer box is connected to a fertilizer guide pipe, the other end of the fertilizer guide pipe is located behind the trenching wheel, a seed box is arranged above the rear part of the frame, a seeding tank is arranged between the fertilizer box and the seed box, the lower end of the seeding tank is located above a ditcher, a reshaper is arranged behind the ditcher, a film coating rack is arranged behind the reshaper, two sides of the frame are provided with soil taking and covering devices, and an adjustment rod device is arranged between the soil taking and covering devices and the frame. The adjustable potato whole-film double-furrow seeder is suitable for a potato whole-film double-furrow seeding drought resistance technology in the northwest drought region, realizes integration of seeding, deep fertilization, ridging, pressing shaping, whole-film covering and soil taking and covering, and realizes adjustment of plantation depth and the amount of soil pressing potatoes.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an adjustable potato full-film double-furrow fertilization, seeding, film-covering and soil-covering combined operation machine in the dry farming area of ​​Northwest China. Background technique [0002] Potato full-film double-furrow sowing cultivation technology is a drought-resistant planting technology suitable for arid and semi-arid areas in northern my country by raising large and small ridges according to the width, implementing full ground coverage, and integrating moisture conservation, rain collection, temperature increase, and production increase. Its main advantages are: by covering all the large and small ridges with plastic film, fully collecting all the rainfall during the potato growth period, effectively solving the problem that the sowing is seriously affected by the spring drought in dry farming areas, thereby ensuring the normal emergence of pota...

AI Technical Summary

Problems solved by technology

At present, the full-film double-furrow film-laying machine is widely used, and the planting method of artificial on-demand planting is labor-intensive, and the sowing depth cannot meet the agronomic requirements, which will affect the quality of potatoes.

At present, the domestic potato full-film double-furrow planter has a fixed operating depth, and the gearbox provides the driving power of the whole machine. The operation is not precise enough, and the operation effect cannot meet the demand.

The soil taking and covering device cannot be adjusted, which limits the soil demand for pressing soil on the film and pressing the edge of the film when covering the film.
