Deep scarifying, stubble cleaning and soil pulverizing machine

Abstract

A deep scarifying, stubble cleaning and soil pulverizing machine comprises a large machine frame, wherein a front three-point linkage device is arranged at the front end of the large machine frame, a rear three-point linkage device is arranged at the rear end of the large machine frame, a deep scarifying is arranged below the large machine frame, a disc type stubble cleaning device is arranged on the portion, behind the deep scarifying device, of the rear three-point linkage device, and a soil pulverizing device is arranged at the rear end of the disc type stubble cleaning device. By the adoption of the machine, work which needs to be done in three times during previous agricultural production can be done at a time, and labor productivity is improved effectively. The deep scarifying device directly breaks a plow pan to guarantee crop root growth and exchange of moisture and air of deep soil, and a buffer device designed in the deep scarifying device can reduce the damage of hard objects such as stone and tree roots in soil to a deep shovel to the maximum degree. Furthermore, working resistance can be reduced by means of self-excited vibration. A damping bar designed in the disc type stubble cleaning device not only can absorb shock, but also has a terrain simulating function, and the working effect of the machine is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a subsoiler for removing stubble and breaking soil in the dry agricultural area of ​​Northwest China. technical background [0002] Land desertification and degradation are serious in dry-farming agricultural areas in Northwest my country. Most farmers use small-scale machinery to plow and prepare the land. The plow layer becomes shallow, and the ability to retain water and fertilizer is poor. Agricultural production is affected by climate every year. With the rapid increase in population and the continuous expansion of cultivated land, the use of chemical fertilizers and pesticides increases, soil compaction, bulk density increases, porosity decreases and other physical properties deteriorate, premium water storage capacity decreases, and cultivated land becomes more and more barren. At the same time, a layer of hard soil is formed at the bottom of the...

AI Technical Summary

Problems solved by technology

However, at present, subsoiling machinery at home and abroad cannot achieve the functions of stubble removal and soil crushing at the same time.

The separation of stubble and crushed soil is not only labor-intensive and labor-intensive; it will also cause pollution during the separation operation, which seriously threatens the health of workers
