Front double-row three-column straw cleaning machine

Abstract

The invention provides a front double-row three-column straw cleaning machine. The machine comprises a main machine frame, a connecting frame, a lower support, a cleaning disc frame, a cleaning disc, a hydraulic cylinder, a compressed spring rod, a compressed spring, a short connecting pin, and a long connecting pin. During operation, the front double-row three-column straw cleaning machine is installed at the position of a front counter weight of a tractor, the hydraulic cylinder of the cleaning machine controls a machine tool to ascend and descend, the cleaning disc rotates under lateral force in the advancing direction, and elastic teeth on the cleaning disc distribute straw to the two sides, so that straw cleaning is achieved; and the working angle of a raking disc is determined by adjusting the installation angle of the cleaning disc frame, so that the width of the cleaned straw is determined. The front double-row three-column straw cleaning machine is a breakthrough of a mechanization technology in the whole process of protective farming, and solves the problem that seeding is affected by full-amount straw coverage.

Description

technical field [0001] The invention belongs to the technical field of corn protective tillage mechanization, and relates to a device for cleaning a planting area under the condition of full straw coverage. Background technique [0002] In recent years, the area of ​​corn planted with conservation tillage technology in my country has continued to increase, but there are still certain restrictions on conservation tillage technology. The amount of straw coverage is required to be less than 30%, otherwise the no-tillage planter will not work normally, seriously If it is to meet the requirements of conservation tillage technology, most of the excess straw will be incinerated, seriously polluting the environment and wasting straw resources. At the same time, due to wind erosion, water erosion and extensive use of chemical fertilizers, land protection is backward, resulting in soil compaction and extremely serious soil erosion. Therefore, the technology of returning full amount of...

Problems solved by technology

[0002] In recent years, the area of ​​corn planted with conservation tillage technology in my country has continued to increase, but there are still certain restrictions on conservation tillage technology. The amount of straw coverage is required to be less than 30%, otherwise the no-tillage planter will not work normally, seriously Affect the quality of sowing. If the requirements of conservation tillage technology are to be met, most of the extra straw will be incinerated, which seriously pollutes the environment and wastes straw resources.

At the same time, due to wind erosion, water erosion and extensive use of chemical fertilizers, land protection is backward, resulting in soil compaction and extremely serious soil erosion

Therefore, the technology of returning the full amount of straw to the field is gradually being promoted and expanded. However, returning the full amount of straw to the field has brought difficulties to no-tillage planting.
