Grass cutter

Abstract

The invention relates to a grass cutter which comprises a shell, a safety guard, wheels and a cutting device provided with blades, wherein the safety guard is arranged outside the shell; the wheels are used for supporting the shell; the cutting device is arranged under the shell, and the rotating blades perform cutting operation, and the cutting device performs eccentric cutting operation; the safety guard comprises an inner layer and an outer layer, and a height difference is formed between the inner layer and the outer layer. When the grass cutter touches an obstacle or works on a boundary line, as the cutting device can perform the eccentric cutting operation, a gap between the cutting device and the safety guard can be smaller, so that more grass or vegetations can be cut. By utilization of the safety guard with a double-layer structure, particularly, when the grass cutter is carried, the safety standards can be met, and good safety protection measures can be achieved.

Description

technical field [0001] The invention relates to the field of garden machinery, in particular to a lawnmower. Background technique [0002] A lawn mower is a mechanical tool used to mow lawns, vegetation, etc. A cutting device of the lawn mower is arranged under the housing, and the cutting device is used to perform cutting operations. Because the blade in the cutting device is relatively sharp, it is easy to cause harm to people and animals. Usually, a safety shield is provided outside the housing of the lawn mower, so that there is a large enough gap between the blade in the cutting device and the inwall of the safety shield. But there will be obstacles more or less within the range of use of the lawnmower. When the lawnmower hits an obstacle, because there is a gap between the blade and the inner wall of the safety guard, it will cause a corresponding gap in the gap. The grass or vegetation in the position cannot be cut, which will affect the cutting effect of the lawn m...

Problems solved by technology

But there will be obstacles more or less within the range of use of the lawnmower. When the lawnmower hits an obstacle, because there is a gap between the blade and the inner wall of the safety guard, it will cause a corresponding gap in the gap. The grass or vegetation in the position cannot be cut, which will affect the cutting effect of the lawn mower

[0003] If the gap between the inner wall of the safety shield and the blade is set smaller, although the lawn mower can cut grass or vegetation as much as possible when it runs into an obstacle, but because the gap between the housing and the blade is too small, During use, it will cause unnecessary harm to people and animals, and the lawn mower cannot meet the required safety standards.
