Abstract

A cutting knife of a lawn mower according to the present invention comprises a knife body located below the lawn mower and horizontally rotating around a knife shaft A, the knife shaft A is fixed to the knife body and connected in rotation with the lawn mower; the knife shaft A shaft sleeve is set on the upper coaxial sleeve, and the shaft sleeve is fixed to the lawn mower. An auxiliary knife is connected horizontally under the cutter body. The knife axis B of the auxiliary knife passes through the cutter body upwards and is driven by the shaft sleeve. connected, and the auxiliary knife is fixedly connected with the knife shaft B. In the present invention, by installing an auxiliary knife at the lower part of the cutter body, secondary cutting is performed on the position where missed cuts are likely to occur in the central area of ​​the lower part of the cutter body, so as to ensure that there is no missing cut at the lower part of the cutter body.

Description

technical field [0001] The invention relates to a lawnmower, in particular to a cutting knife of the lawnmower. Background technique [0002] Lawn mower (Lawn mowCr) is also known as weeder, lawnmower, lawn trimmer and so on. 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. [0003] The cutterhead is installed on the walking wheel, the cutterhead is equipped with an engine, and the output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to increase the speed a lot, which saves the working time of the weeding workers and reduces a lot of human resources. [0004] In the current lawn mower, the mowers used have less kinetic energy in the vicinity of the connection position between the knife shaft and the rotary knife during the rotary mowing process, so missing cuts and uneven cutting a...
