Description

Mower with buffer mechanism

Technical Field

The invention relates to mowing equipment, in particular to a mower with a buffer mechanism, and belongs to the technical field of gardening treatment equipment.

Background

Along with the rapid development of modern agriculture, the traditional manual working mode not only consumes manpower but also has low efficiency, obviously can not meet the modern production requirement, and the weeding mode is changed from manual weeding to chemical weeding, but the chemical is inevitably left, and causes injury to human body. And the chemical agent can pollute the land and destroy the ecological environment, which is contrary to the green development idea. Therefore, the more environment-friendly mechanical weeding mode is accepted by the masses of people. The mechanical weeding mode can greatly reduce labor cost, has high weeding efficiency, can promote the growth of crops, reduces the pesticide residue of weeding agents, and is favorable for protecting ecological environment. Currently, lawnmowers have been widely used for weeding large-area planting fields.

In mower construction, the most important is the mowing portion. When the mowing mechanism works, the mowing mechanism rotates around the connecting hinge point by pushing of the air cylinder, so that mowing height is adjusted. When grass of a certain height needs to be cut, the air cylinder adjusts the box body to the height through expansion and contraction and keeps the height unchanged, and at the moment, the air cylinder needs to provide larger supporting force. The mower can generate larger vibration when mowing in walking, and the vibration can have larger influence on the performance and the service life of the cylinder.
