Abstract

A soil loosener comprises a handle, a power output portion, a middle shaft and at least one operating component, wherein the handle for a user to hold is provided with a switch, the power output portion is connected with the handle and comprises a casing, a motor and a power output shaft, the motor is contained in the casing and controlled through the switch, the power output shaft is driven to rotate by the motor, the middle shaft is provided with a middle shaft axis and is driven by the power output shaft to rotate around the middle shaft axis, each operating component comprises an operating shaft and an operating head, each operating shaft is connected with the middle shaft and driven by the middle shaft to rotate around the middle shaft axis, each operating head is mounted on the corresponding operating shaft to loosen soil, each operating shaft is provided with an operating shaft axis, each operating head is capable of rotating relative to the corresponding rotating shaft, and the middle shaft axis and each operating shaft axis form an acute angle. The operating heads are driven by the operating shafts to axially swing back and forth along the middle shaft, so that the soil loosening range is widened.

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...
