a weeder

Abstract

The invention discloses a weeder, comprising a frame, a driving device, a rotating disk, a pin shaft and a cutter head, the driving device is arranged on the frame, and the driving device is fixedly connected to the frame; the rotating The disc is rotatably connected to the frame, and the driving device drives and connects the rotatable disc to make the rotatable disc rotate around the axis of the rotatable disc; a step hole, the inner bottom surface of the step hole runs through the thickness of the rotating disc, and the circumferential surface of the pin shaft is provided with a groove surrounding the circumferential surface of the pin shaft, the groove and the step hole Step concave-convex fit; the upper end surface of the cutter head is provided with a plurality of bushes, the pins are inserted into the bushes one by one, and the bushes are fixedly connected to the pins. The invention provides a weeding machine capable of avoiding the bending of the rotating shaft on the cutter head caused by the collision, which causes the cutter head to be stuck.

Description

Technical field [0001] The present invention relates to the technical field of weeding devices, particularly a weeding machine. Background technique [0002] In daily life, the worculars can be used to cut weeds in the grass, especially nearby houses, usually need to trim to weeds, avoiding the impact of mice, snakes in weeds and even threatening People's life and health. [0003] In the process of using a conventional herbzer for weeding, the motor in the traditional weanger is connected by the rotating shaft, the rotating shaft is connected to the nut, and the cutter is disposed between the nut and the motor, the rotating shaft. Travel vertical setting. During use, once the cutter or nut collides with hard objects such as stones, it is possible to directly affect the shaft of the connecting motor. Once the rotation is bent, it may cause the cutter disk to die, and if the shaft is hard-connected The outer circumference of the shaft is surrounded, and if the rotation is bent, the...

AI Technical Summary

Problems solved by technology

During use, once the cutter head or nut collides with hard objects such as stones, it may directly affect the shaft connected to the motor. Once the shaft bends, it may cause the cutter head to be stuck. Surround the periphery of the rotating shaft to avoid bending of the rotating shaft. After the cutterhead collides with hard objects outside, the cutterhead may break and splash outwards. Therefore, there is a risk that the cutterhead fragments that are disconnected and splashed outwards will hurt people. Hidden danger
