Problems solved by technology

Moreover, reducing the working speed of the lawn mower can effectively reduce the noise generated by the lawn mower, but it will also bring about a decrease in efficiency when cutting higher grass
Therefore, it is difficult to select a suitable rotational speed to achieve a balance between mowing efficiency and noise, and this will make the mower only cut shallow grass, thereby limiting the range of use of the mower

Abstract

The invention discloses a mowing machine which comprises a shell, a motor, a blade, a power providing device and a speed controlling device, wherein the motor is connected to the shell and is provided with a motor shaft; the blade is used for mowing grass and is connected to the motor shaft and provided with at least one cutting edge; the power providing device provides energy for the motor when the mowing machine works so as to drive the blade to rotate at a cutting speed; and the speed controlling device can be used for selectively fixing the cutting speed on at least one preset constant speed.

Description

technical field [0001] The invention relates to an electric lawnmower, in particular to an electric lawnmower capable of cutting at a constant rotation speed. Background technique [0002] As a tool suitable for fast and efficient lawn trimming, lawn mowers are widely used in urban greening and family weeding. In consideration of reducing air pollution, electric lawn mowers are more popular than gas-powered lawn mowers, while DC cordless lawn mowers are more popular with users due to their freedom of movement, and DC motors have good tuning Speed ​​performance, such as stepless speed regulation, wide speed regulation range, good low-speed performance, high starting torque, high efficiency, etc. [0003] However, all kinds of lawnmowers still bring serious noise pollution to the urban environment. [0004] The noise of the lawn mower is mainly produced by the high-speed rotation of the motor and the blade, which can usually reach more than 90 decibels, and people will feel ...
