Abstract

The invention discloses a cutter of a mower. The cutter comprises a cutter body which is arranged under the mower and horizontally rotates around a cutter shaft A, wherein the cutter shaft A is fixedto the cutter body and is rotatably connected with the mower, the cutter shaft is coaxially sleeved by a shaft sleeve, and the shaft sleeve is fixed to the mower; and an auxiliary knife is connected to the lower part of the cutter body in a horizontal and rotary mode, a cutter shaft B of the auxiliary knife passes through the cutter body and is connected with the shaft sleeve in a transmission mode, and the auxiliary knife is fixedly connected with the cutter shaft B. By installing the auxiliary knife at the lower part of the cutter body, secondary cutting can be performed on positions which have easy cutting leakage in the central area of the lower part of the cutter body, so that no phenomena of cutting leakage of the lower part of the cutter body are ensured.

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...
