Front-loading push pressing type machine for returning straw to rows, capable of being variable in single row and dual rows

Abstract

The invention provides a front-loading push pressing type machine for returning straw to rows, capable of being variable in a single row and dual rows. The front-loading push pressing type machine comprises a grass raking disk, a grass raking disk bearing seat, a main machine frame, an upper machine frame, a lower machine frame, a lifting oil cylinder, front brackets, a lower connecting frame, a grass raking disk supporting rod, a pressure spring shaft, a pressure spring, a right angle clip and a supporting plate. In different connecting manners of components, a single-row push pressing type machine for returning straw to rows can be formed, a dual-row push pressing type machine for returning straw to rows can also be formed, and the front-loading push pressing type machine is simple and convenient to mount and can be adapted to matching requirements of various planting machine tools. During operations, the front-loading push pressing type machine disclosed by the invention is mountedat a counter weight position in front of a tractor, the lifting oil cylinder of the machine for returning straw to rows is used for controlling lifting of the machine tools, the grass raking disk is subjected to side force in the advancing direction to turn, flexible teeth on the grass raking disk are used for separating and poking the straw to two sides, and the purpose of returning the straw tothe rows can be realized; and through regulating the mounting hole position of the supporting plate, the working angle of the grass raking disk is determined, the positions of the front brackets are regulated, and the width of the rows on which the straw is returned can be determined. The front-loading push pressing type machine disclosed by the invention is breakthrough of a protective cultivation whole-course mechanized technique, and difficult problems of sowing under whole-quantity straw covering can be solved.

Description

technical field [0001] The invention belongs to the technical field of corn protective tillage mechanization, and relates to a device for row-wise processing of straw covered on the ground before planting or at the same time of planting, and can perform single and double row changes according to the requirements of straw processing. 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 ...

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
