Front push-press type double-row corn straw sorting machine

Abstract

The invention provides a front push-press type double-row corn straw sorting machine. The front push-press type double-row corn straw sorting machine comprises a straw raking disc, a straw raking discbearing seat, a lower rack, an upper rack, a main rack, a lifting oil cylinder, a pressure spring shaft, a pressure spring, a front bracket, a right-angle clamp and a supporting plate. During operation, the front push-press type double-row corn straw sorting machine is mounted at a front counterweight position of a tractor; the lifting oil cylinder of the sorting machine controls the lifting of amachine tool; the straw raking disc rotates under the action of lateral force in the advancing direction; elastic teeth on the straw raking disc are used for distributing straw to two sides to realize straw sorting; the working angle of the straw raking disc is determined by adjusting a mounting hole position of the supporting plate; and the position of the front bracket is adjusted to determinethe straw sorting width. The front push-press type double-row corn straw sorting machine is a breakthrough of a whole-process mechanical technology of protective tillage, and the problem of sowing under full straw coverage is solved.

Description

technical field [0001] The invention belongs to the technical field of corn protective tillage mechanization, and relates to a device for sorting straws covered on the ground before planting or at the same time of 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 erosio...

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
