Abstract

The utility model relates to the technical field of tillers, specifically to a tiller for agricultural production, comprising a moving mechanism, a tiller mechanism, and a movable mechanism. A driving rod of a driving shell drives a transmission crawler to rotate and advance on the ground. A mounting wheel of a mounting shell sleeved on the surface of the driving shell rotates through a mounting hole in cooperation with a rotating shaft at the bottom end of a threaded rod. A transmission cutter head is inserted into the ground and surrounds the overall device to loosen the soil, which is convenient for workers to quickly loosen the soil of a large area of ​​land.

Description

Technical Field

[0001] The utility model relates to the technical field of soil scarifiers, in particular to a soil scarifier for agricultural production. Background Art

[0002] A scarifier is a machine that uses a toothed scarifier to rake hard soil, frozen soil, old road surface and even medium-hard rock in earthwork construction. According to the connection between the scarifier and the tractor, there are two types: towed type and hanging type. The traction provided by the tractor and the weight of the scarifier are used to make the rake teeth cut into the soil, loosen the hard soil, and leave a loose soil zone after the machine passes. It is often used for pre-scarring operations before bulldozers or scrapers.

[0003] As disclosed in the authorization announcement number CN206092824U, a tiller is disclosed, including a push rod, a power device, a walking wheel, a transmission mechanism and a working mechanism, wherein the power device transmits power to the working mechanism through the transmission mechanism, and is characterized in that the transmission mechanism is connected to the working mechanism through a bevel gear assembly. In the above manner, the tiller of the utility model can reduce the rotation speed and increase the torque, convert the radial torque into the axial torque, and improve the synchronization and stability, but it does not solve the problem of facilitating the staff to quickly loosen the soil of a large area of ​​land, nor does it solve the problem of facilitating the staff to adjust the loosening effect of various depths: for this reason, we propose a tiller for agricultural production.
