Anti-drag subsoiling and intertilling device allowing quick replacement of subsoiling and intertilling shovel points

Abstract

The invention relates to the field of agricultural machinery and relates to an anti-drag subsoiling and intertilling device allowing quick replacement of subsoiling and intertilling shovel points. The device comprises an anti-drag unit (1) and a quick replacement unit (2), wherein the anti-drag unit (1) comprises a first fixed seat (11), a second fixed seat (12), a spring assembly body (13) and a connecting plate (14); the quick replacement unit (2) comprises a shovel shaft (21), a transfer assembly body (22) and the intertilling shovel point (23) or subsoiling shovel point (24); one end of the spring assembly body (13) and the first fixed seat (11) form rotational connection through a hinge pin; the connecting plate (14), the other end of the spring assembly body (13) and the second fixed seat (12) form rotational connection through a hinge pin, and the connecting plate (14) is fixedly connected with the upper part of the shovel shaft (21); the transfer assembly body (22) is fixedly connected to the lower part of the shovel shaft (21); the subsoiling and intertilling shovel points are quickly replaced by the aid of the transfer assembly body (22). The device is time-saving, the machine utilization rate is high, the cultivation drag is decreased, and the power consumption is reduced.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a drag-reducing subsoiling and cultivating device for quickly replacing the tip of a subsoiling and cultivating blade. Background technique [0002] The subsoiler can destroy the hard plow bottom layer, deepen the plow layer, make the soil form a structure with both virtual and solid, increase the water permeability and air permeability of the soil, and improve the growth environment of crops. Subsoiling technology can greatly increase the yield of crops and is an important technology for increasing production. [0003] The cultivator shallowly overturns the soil and loosens the surface soil, which can increase soil air permeability, increase ground temperature, promote microbial activity and nutrient effectiveness, remove weeds, promote root development, and adjust soil moisture. Intertillage technology can improve crop yields has a positive meaning. [0004] In order to ...

AI Technical Summary

Problems solved by technology

Since the shovel handle and the shovel tip are the main stress-bearing parts, they are mostly fixed by bolts, and the replacement is time-consuming and laborious. If we can design a device for easy connection and replacement of the shovel tip, these problems can be easily solved.
