Anti-drag subsoiler with shovel tip rotation

Abstract

The invention discloses an anti-drag subsoiler with shovel tip rotation. The anti-drag subsoiler comprises a rack; two sides of the rack are symmetrically provided with depth limiting devices; the topof the rack is connected with a suspension device; the rack is also provided with a gearbox; a power output shaft of the gearbox is connected with a power transmission device; a power output shaft ofthe power transmission device is connected with a subsoiling device; the subsoiling device comprises a shovel tip and a shovel handle; the top of the shovel handle is fixedly connected with the rack,and the bottom of the shovel handle is provided with a sleeve base; the shovel tip passes through the sleeve base; and one end of the shovel tip is exposed out of the sleeve base, and the other end of the shovel tip is connected with the power output shaft of the power transmission device. The invention provides a brand new subsoiler, a subsoiling shovel tip of the subsoiler is adopted to rotate,and the rotation operation on a plow pan layer and a core soil layer with relatively large compact degree and volume weight is only performed, so that the drag of the subsoiling operation is effectively reduced, no impact acts on broken soil, the bottom of a subsoiled ditch after operation is level, meanwhile, the power consumption of the operation is reduced, and the reliability of subsoiling operation is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a shovel point rotating drag-reducing subsoiler. Background technique [0002] Subsoiling is one of the core technologies of conservation tillage. After subsoiling the soil, it can break the hard plow bottom layer, improve water use efficiency, reduce soil erosion, enhance water and soil conservation capacity, improve the growth environment of crop roots, and benefit crop roots. Therefore, subsoiling is an important technology to increase the yield of deep-rooted crops. [0003] The subsoiler is a key tool for mechanized subsoiling operations, and its operating energy consumption is 3 to 5 times that of crop harvesting machines. How to reduce the resistance of subsoiling operations is a key issue in the promotion of subsoiling technology. Divide the soil plow layer that needs deep loosening operation into top soil layer (plow layer), plow bottom layer and core soi...

AI Technical Summary

Problems solved by technology

Although the vibrating subsoiler reduces the working resistance, there are still the following problems: 1) it has an impact compaction effect on the broken soil; 2) at the same time, the bottom of the subsoiling ditch is uneven after operation; 3) the vibration is easy to make the subsoiling shovel Fatigue damage of subsoilers and other components will affect the service life of the subsoiler and reduce the reliability of the operation of the subsoiler
