Problems solved by technology

As a result, if the lawn mower encounters relatively high and dense grass during work, the resistance will increase significantly, and the drive wheel of the machine will slip, which will not only lose the effective mowing performance of the lawn mower, but also damage the grass
[0004] In addition, the safety protection structure of the existing lawnmower increases the difficulty of mowing and greatly reduces the efficiency

Abstract

The invention discloses a height self-adjusting cutting device and self-walking equipment. The height self-adjusting cutting device comprises a shell and a cutting device arranged in the shell, a vertical elastic unit is arranged between the cutting device and the shell, when the cutting device receives buoyancy of grass, the vertical elastic unit is compressed to enable the cutting device to float upwards, and the resistance of a mower is reduced. When the mower encounters high and high-density grass, the cutting device can adapt to the actual working condition of the grass, and the height can be automatically adjusted.

Description

technical field [0001] The invention discloses a height self-adjusting cutting device and self-propelled equipment. Background technique [0002] The working unit of the lawn mowing robot is a high-speed rotating cutterhead with sharp blades. Therefore, it is necessary to have an effective protective structure for the cutting unit on the lawn mower to prevent injury to the user. [0003] Most of the current protective structures are to reduce the height of the peripheral casing, or to fix an additional protective structure on the main casing. The much lower housing height increases safety at the expense of mower performance. As a result, if the lawn mower encounters relatively high and dense grass during work, the resistance will increase significantly, and the drive wheel of the machine will slip, which will not only lose the effective mowing performance of the lawn mower, but also damage the grass. [0004] In addition, the safety protection structure of the existing la...
