Technical Field

[0001] The utility model relates to the technical field of weeding devices, in particular to a garden weeding device. Background Art

[0002] In garden maintenance and management, weeding is an important and frequent task. With the progress of technology, traditional manual weeding methods have gradually been replaced by various mechanized and automated weeding devices. Among them, a widely used garden weeding device rotates a cutter head driven by a motor to cut and remove weeds.

[0003] For the garden weeding devices on the current market, the motor is directly connected to the cutter head through a drive shaft. When the cutter head rotates at a high speed, it will inevitably encounter the problem of weed entanglement. Especially when dealing with wet or highly tough weeds, these weeds are prone to entangle on the drive shaft, resulting in the obstruction of the drive shaft rotation and even possible motor overload, seriously affecting the working efficiency and safety of the weeding device. Therefore, a garden weeding device is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model aims to solve at least one of the technical defects.

The output end of the motor is fixedly connected with a drive shaft. The bottom end of the drive shaft is fixedly connected with a cutter head.

The limiting sleeve is rotationally connected with the drive shaft. A plurality of cutting plates are fixedly connected to the outer surface of the limiting sleeve. A cutting disc is fixedly connected to the top surface of the cutter head. The cutting disc is slidably connected with the cutting plates.

[0007] Preferably, according to any of the above solutions, a guide rod is fixedly connected to the top surface of the lifting frame. The guide rod is slidably connected with the L-shaped bracket.

[0008] Preferably, according to any of the above solutions, a through hole is formed through the bottom surface of the chassis, and the connecting rod is located inside the through hole.
