A drag-reducing subsoiling and cultivating device for quickly replacing subsoiling and cultivating shovel tips

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, and particularly relates to a drag-reducing deep loosening and field tillage device for quickly replacing the tip of a deep loosening and field tillage shovel. Background technique [0002] The subsoiler can destroy the hard bottom of the plough, deepen the ploughing layer, make the soil form a structure of virtual and solid coexistence, increase the water permeability and air permeability of the soil, and improve the growth environment of crops. Subsoiling technology can greatly increase crop yields and is an important yield-increasing technology. [0003] The field cultivator overturns the soil in a shallow layer and loosens the surface soil, which can increase soil permeability, increase ground temperature, promote microbial activity and nutrient efficiency, remove weeds, promote root development, and adjust soil moisture conditions. Field tillage technology is useful for increasing crop yields....

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.
