Summer cotton precision no-tillage planter capable of realizing seedling strip cleaning

Abstract

The invention provides a summer cotton precision no-tillage planter capable of realizing seedling strip cleaning. The planter comprises a frame; a depth wheel is installed on a depth wheel fixing sleeve; a speed changing box is fixed at the front part of the frame; a fertilizer box is fixed at the rear part of the frame; side plates are respectively arranged on two sides of the frame; a grass and stubble cleaning rotary tillage mechanism is installed between the two side plates; a fertilizer applicator is fixed on the rear beam of the frame; multiple groups of profiling seeding pressing single bodies are also connected with the rear part of the rear beam of the frame; a transmission six-edge shaft is installed on an auxiliary fixing device on the rear side of the rear beam of the frame through a bearing; a transmission land wheel is connected with a transmission six-edge shaft bracket through a shaft sleeve. The planter can perform summer cotton precision no-tillage direct seeding on earth surface covered with stubble after wheat harvest, can accomplish stubble cleaning, grass cleaning, shallow rotary tillage, fertilization, seeding and pressing operation at a time, is beneficial to racing against farming season, has good grass and stubble cleaning and soil crushing effects, can guarantee the seeding depth uniformity, meets agronomic requirements of summer cotton seeding, and is reasonable and novel in whole, high in adaptability, economical and reliable.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a summer cotton precision no-tillage seeder which is especially suitable for the Yellow River Delta region and can realize the cleaning of seedling belts. Background technique [0002] The Yellow River Delta region is the main grain and cotton production area in my country, and the phenomenon of grain and cotton competition for land is prominent, and the plastic film residue caused by plastic film covering in spring cotton planting has become the largest pollution source of dry farming agriculture. The implementation of wheat-cotton rotation in this region can effectively solve the contradiction between grain and cotton planting, avoid white pollution, improve agricultural efficiency, and increase farmers' income, which is of great significance for ensuring national food security and stable cotton supply. The wheat-cotton rotation is implemented in the Yellow River Delta region, that is...

AI Technical Summary

Problems solved by technology

The wheat-cotton rotation is implemented in the Yellow River Delta region, that is, after the wheat is harvested, the stubble is cleared or the stubble is planted / transplanted. However, the cost of seedling cultivation and transplanting is high. According to the characteristics of cotton planting in the Yellow River Delta region, direct-seeding super early-maturing short-season cotton after wheat is the best way to realize wheat-cotton production. The best way to rotate crops, which is an urgent need to develop precision no-tillage planting machinery that can directly broadcast summer cotton in stubble after wheat combined harvesting, but there is no such molding machine at present
