Cutter disk anti-dithering device and mower

Abstract

The invention provides a cutter disk anti-dithering device and a mower. The cutter disk anti-dithering device comprises a height adjustment rotary knob, a mowing motor frame and a mowing motor. The inner side of the height adjusting rotary knob is provided with a first rotating gear line, and the outer side of the mowing motor frame is provided with a second rotating gear line; the first rotatinggear line and the second rotating gear line are meshed with each other. The mowing motor is fixed in the mowing motor frame, and the inner side of the height adjusting rotary knob is also provided with an arc-shaped spring sheet; the first end of the arc-shaped spring sheet is fixed on the height adjusting rotary knob, and an arc-shaped protruding face of the arc-shaped spring sheet makes contactwith the first rotating gear line. The mower includes a mower housing, walking rear wheels, universal walking front wheels, a power-supply power source, a main controller, the cutter disk anti-dithering device and the like. The cutter disk anti-dithering device can be applied to intelligent walking devices and equipment to realize the anti-dithering function of a cutter disk, prevents acute dithering of a cutter disk height adjusting assembly, a mowing motor assembly and a cutter disk assembly, and can reduce the noise of operation of the mower.

Description

technical field [0001] The invention belongs to the technical field of garden tools, and relates to an intelligent walking device and equipment, in particular to a cutterhead anti-vibration device and a lawn mower thereof. Background technique [0002] As a common garden tool at present, the smart lawn mower can automatically realize the lawn trimming work. When the power is insufficient, it can automatically return to the charging stand for charging. Therefore, it is favored by users for its advantages of automation and intelligence. [0003] Existing smart walking devices such as smart lawn mowers are based on electronic fences for walking navigation and mowing activities. Among them, the signal lines buried around the lawn play the role of electronic fence. After the trimming operation of the intelligent lawn mower, a uniform and flat lawn can be obtained. Early intelligent lawn mowers were not equipped with a cutter head height adjustment device, so the reserved lawn h...

AI Technical Summary

Problems solved by technology

When the intelligent lawn mower is mowing and walking, the rotation of the mowing motor and the vibration caused by the walking of the lawn mower will easily cause the adjustment knob, motor assembly and cutter head assembly to vibrate along their respective axes, so it is easy to produce Louder noise and easier damage to components such as the deck height adjustment assembly, mowing motor assembly, and deck assembly due to vibration

[0004] In view of the current situation, the existing technical solutions cannot fundamentally solve the above technical problems
