Rear-mounted four-row adjustable corn straw strip collecting machine

Abstract

The invention provides a rear-mounted four-row adjustable corn straw strip collecting machine. The rear-mounted four-row adjustable corn straw strip collecting machine comprises a main machine frame,a left extending frame, a right extending frame, connecting frames, lower brackets, horizontal supporting beams, front brackets, left raking disk bearing seats, right raking disk bearing seats, pressure springs, supporting plates, right angle clamps, lifting oil cylinders, raking disks, and pressure spring shafts. During operation, the rear-mounted four-row adjustable corn straw strip collecting machine is mounted at a rear three-point suspension structure of a tractor through suspension points; the suspension structure of the tractor is used for controlling the lifting of tools; the lifting oil cylinders are used for controlling contracting and extending of the left extending frame and the right extending frame; the raking disks rotate under the stress of lateral force in the advancing direction; elastic teeth on the raking disks are used for toggling straw to two sides, so that straw strip collection is realized; through adjusting the positions of the horizontal supporting beams andthe front brackets, four complete blank strips or three complete blank strips and half blank strips on the left side and the right side can be cleaned out by the strip collecting machine; the rear-mounted four-row adjustable corn straw strip collecting machine disclosed by the invention is a breakthrough of a whole-process mechanized technique of protective tillage; and the difficult problem of sowing under covering of the whole straw is solved.

Description

technical field [0001] The invention belongs to the technical field of corn protective tillage mechanization, and relates to a device for stripping and processing straw covered on the ground before planting. Background technique [0002] In recent years, the area of ​​corn planted by conservation tillage technology in my country has continued to increase. However, compared with some developed countries, there are still certain restrictions on conservation tillage technology. The amount of straw coverage cannot exceed 30%, otherwise no-tillage planters It will not work normally and seriously affect the quality of operation. If the requirements of conservation tillage technology are to be met, the excess straw will be incinerated in most cases, seriously polluting the environment and wasting straw resources. At the same time, due to the backwardness of corn planting and farming models in my country, coupled with excessive development and utilization, wind erosion, water erosion...

Problems solved by technology

[0002] In recent years, the area of ​​corn planted by conservation tillage technology in my country has continued to increase. However, compared with some developed countries, there are still certain restrictions on conservation tillage technology. The amount of straw coverage cannot exceed 30%, otherwise no-tillage planters It will not work normally, seriously affecting the quality of work. If the requirements of conservation tillage technology are to be met, most of the excess straw will be incinerated, seriously polluting the environment and wasting straw resources.

At the same time, due to the backwardness of corn planting and farming models in my country, coupled with excessive development and utilization, wind erosion, water erosion, and extensive use of chemical fertilizers, the lack of land protection methods has caused soil compaction, and the organic matter of the land has changed from 6-8% when it was reclaimed. has dropped below 2%, and soil erosion is extremely serious
