Grass surface adaptive laminated weeding machine for municipal landscape engineering

Abstract

The invention belongs to the technical field of weeding, and particularly relates to a grass surface adaptive laminated weeding machine for municipal landscape engineering. The weeding machine comprises a first cutting mechanism, a protective top cover, a tooth ring, a ring shaft, a tooth ring side wall, a second cutting mechanism, a supporting top cover, a volute spiral spring, a protective spring, a motor, ring teeth, a motor rotating shaft and an inner ring, wherein the inner ring and outer ring of the weeding machine have a one-way clutch relation, the inner ring can drive the outer ring to rotate, but the outer ring cannot drive the inner ring to rotate, so that when the first cutting mechanism is wound by weed, the second cutting mechanism can rotate forward relative to the first cutting mechanism to simultaneously cut the weed; a cutting blade guide groove is formed in the upper end of a cutting blade, and when the cutting blade is bent, a guide plate can slide in the cutting blade guide groove, thereby preventing interference; the torque of the ring shaft is increased by using a planet wheel structure and then the torque of the second cutting mechanism is increased, so that the second cutting mechanism can be matched with the first cutting mechanism to cut weed; and the weeding machine is simple in structure and good in using effect.

Description

[0001] Technical field [0002] The invention belongs to the technical field of weeding, and in particular relates to a self-adaptive lamination type weeder for municipal landscape engineering. Background technique [0003] At present, there are various types of weeding machines such as hanging type, rotary type, and reciprocating type in the field of weeding technology. The blade utilizes the high-speed rotation of the engine to greatly increase the output speed, which saves the working time of weeding workers and reduces a lot of human resources. However, there are still many problems. When injecting and cutting grass, it can only be trimmed horizontally along the slope, but not up and down the slope. Moreover, when the cutting disc is entangled by grass, the motor shaft will stop rotating, causing motor failure, so without increasing the cost. It is necessary to design a device that can solve the problem of grass winding cutting blades. [0004] The present invention desig...
