[0002] The existing lawn mower is composed of a motor and a cutter, but it does not have a dust removal function during use, which will lead to poor heat dissipation of the motor, thereby increasing the hidden dangers of the motor. For example, a Chinese patent discloses a "Huangjing and Paris polyphylla weeding device", and its application number is "CN201921461715.1". This device includes a horizontal plate, a bearing is embedded in the top of the horizontal plate, a rotating shaft is sleeved in the bearing, two cutter discs are fixedly installed on the outer wall of the rotating shaft, a partition is fixedly connected to the bottom of the horizontal plate and the corresponding position of one side of the cutter disc, a motor is arranged on the top of the rotating shaft, and the motor Sound-absorbing pads are overlapped on both sides, and a first spring is fixedly connected to one side of the sound-absorbing pad. Slots are opened on both sides of the top of the horizontal plate. This device solves the problem of high noise in traditional lawn mowers by arranging a sound insulation shell, a motor and a shock-absorbing pad, thereby effectively reducing the noise generated by the resonance shaking of the sound insulation shell driven by the motor, reducing the impact of the noise on nearby people during mowing, ensuring the effect of clearing weeds in the medicinal field, and meeting the needs of use.
