Embodiment Construction

[0041] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] refer to Figure 1 to Figure 6 , the scarifier 100 includes: a power source, a handle 2, an extension rod 3 connected to the handle 2, a power output part 4 connected to the extension rod 3, an intermediate shaft 5 driven by the power output part 4, an intermediate shaft mounted on the intermediate shaft 5 The working assembly 6, and the clamping mechanism 7 for axially limiting the working assembly 6. The overall longitudinal direction of the scarifier 100 is set.

[0043] The scarifier 100 includes a handle 2 for being held by a user to scarify the soil. The handle 2 includes a main handle 21 and an auxiliary handle 22 . Both the main handle 21 and the auxiliary handle 22 are ring-shaped, and of course, other shapes suitable for holding, such as a cylindrical shape, are also feasible. The auxiliary handle 22 is arranged in front o...

Abstract

The invention relates to a loosener which comprises a handle, a power output part, a middle shaft and a working assembly, wherein the handle is provided with a switch and is used for being held by a user; the power output part is connected with the handle and comprises a shell, a motor which is accommodated in the shell and is controlled by the switch and a power output shaft driven by the motor to rotate; the middle shaft is driven by the power output shaft to rotate; the working assembly comprises a working shaft and a working head; the working shaft is connected with the middle shaft and is driven by the middle shaft to rotate around the axis of the middle shaft; and the working head is rotatablely arranged on the working shaft and is used for loosening the soil. The switch is switched off or switched on, so that the loosener selects to be in a manual working mode that both the middle shaft and the working shaft do not rotate and the working head rotates relative to the working shaft under the push-pull action of an operator and an electric working mode that the motor, the middle shaft, the working shaft and the working head sequentially carry out transfer movement to loosen the soil.

Description

technical field [0001] The invention relates to a scarifier. Background technique [0002] In agricultural production, cultivating the soil is an essential step, and large-scale machinery can be used to deeply plow the soil and crush large clods of soil. This method of operation is suitable for situations where no crops are growing on the land. [0003] The technology related to the present invention is a technique of loosening soil and crushing clods on the land where crops have been planted and grown. [0004] Patent documents related to the present invention, such as U.S. Patent Publication No. US 4,678,043, disclose a hand-held scarifier, which includes a rod and a support shaft pivotally connected to the rod. The shaft passes through several positioning blocks, and the space between the positioning blocks can be tilted into a ratchet wheel for crushing soil. In the working state, the manpower pushes the scarifier forward, and the ratchet rolls along the set gap to lo...
