Embodiment Construction

[0019] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0020] Such as Figure 1 to Figure 3 As shown, the high-efficiency cutter structure of the lawnmower of the present embodiment includes a drive shaft 1, a cutter shaft 2 is installed on one end of the drive shaft 1, and a cutting blade 5 is installed on the cutter shaft 2, and the outer walls of the two ends of the cutter shaft 2 are respectively supported by Bar 3 is equipped with supporting ring 4, and two supporting rings 4 are fixedly connected cutting blade 5, and cutting blade 5 is inclined to arrange symmetrically around the central axis of cutter shaft 2, and cutting blade 5 has cutting knife groove 51, and cutting knife groove 51 will cut The blade 5 is divided into two parts, so that the weeds falling into the cutter groove 51 can continue to be divided, and the division efficiency is improved.

[0021] The outer walls of both e...

Abstract

The invention relates to a high-efficiency cutting knife structure of a grass cutter. The high-efficiency cutting knife structure comprises a drive shaft, wherein a knife shaft is mounted at one end of the drive shaft, cutting blades are mounted on the knife shaft, a supporting ring is mounted on the outer wall of each of the two ends of the knife shaft by means of supporting rods, the cutting blades are fixedly connected between the two supporting rings and are symmetrically arranged opposite to a center shaft of the knife shaft, and a cutting groove is formed in each of the cutting blade; inner reamers are symmetrically mounted on the outer walls of the two ends of the knife shaft, and an end reamer positioned on the outer end side of the knife shaft is mounted on each of the supporting rods. When the high-efficiency cutting knife structure works, an engine drives the knife shaft to rotate at a high speed; when in rolling, the cutting blades perform continuous cutting on weeds, so that the effect is good, and the efficiency is high; as the cutting blades provided with the cutting grooves are arranged, the cutting efficiency is improved; as the cutting blades are obliquely arranged opposite to the knife shaft, the one-time contact areas between the cutting blades and the weeds are smaller, so that the cutting resistance is reduced, and the cutting speed is improved; as the inner reamers and the end reamers are arranged on the knife shaft, the grass cutting resistance is reduced, and the cutting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a walk-behind rotary tiller. Background technique [0002] A lawn mower is a mechanical tool for mowing lawns, vegetation, etc. It is composed of a cutter head, an engine, a walking wheel, a walking mechanism, a blade, a handrail, and a control part. The cutter head is installed on the walking wheel shaft, the engine is installed on the cutter head, and the output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to mow the grass, which is fast, saves working time and reduces a lot of human resources. [0003] In the existing lawnmowers, the structural design of the lawnmower is not reasonable enough, the mowing efficiency is not high, and the blades are easily damaged. Contents of the invention [0004] The applicant provides a high-efficiency cutter structure of a lawn mower with reasonable structure and high wo...
