Blade and mowing machine

Abstract

The invention provides a blade and a mowing machine. The blade comprises a flat-plate middle portion and end portions on two sides of the middle portion. The edge portions are provided with cutting edges, each end portion comprises a first end portion and a second end portion, each second end portion is positioned between the middle portion and the corresponding first end portion and connected with the middle portion and the corresponding first end portion, and in a longitudinal direction of the middle portion, a ratio of the length of each first end portion to the length of the blade is in arange of 0.045-0.09. Compared with the prior art, the blade and the mowing machine have advantages that cut grass can be smashed completely by the blade to achieve an optimal grass smashing effect, and structural simplicity and low cost are realized.

Description

technical field [0001] The invention relates to a blade and a lawnmower with the blade, belonging to the field of garden tools. Background technique [0002] At present, lawn mowers on the market are roughly divided into two types, lawn mowers with grass collection bags and lawn mowers without grass collection bags, and lawn mowers without grass collection bags are also called grass shredders. Compared with the lawn mower, the lawn shredder does not have a grass collection bag. The grass clippings after cutting are distributed on the lawn. If the grass clippings are too large or aggregated into groups, they will cover the lawn, resulting in poor growth or death of the lawn. Affect the appearance. [0003] At present, the lawn mowers on the market are designed with various shapes and types of blades in order to improve the grass cutting performance, such as: Honda’s double-layer blades, but this type of blade has a complex structure, large size, and high cost , and due to t...

[0003] At present, the lawn mowers on the market are designed with various shapes and types of blades in order to improve the grass cutting performance, such as: Honda’s double-layer blades, but this type of blade has a complex structure, large size, and high cost , and due to the heavy weight, the power requirements for the lawn mower are relatively high. If it is applied to a low-power lawn mower (such as a lawn mower using a lithium battery), the load will be very large, resulting in fast power consumption and mowing Grass efficiency is low
