Cross runout device of grass cutter

Abstract

The invention relates to a cross runout device of a grass cutter, wherein one side of a suspension bracket is fixed with a vertical pipe; a vertical shaft and the teleflex of a support saddle are vertically installed on the vertical pipe; a connecting seat of the machine body is hinged on the support saddle through a lateral pin; a swing mechanism comprises a first connecting rod, a guide bar and a horizontal driving piece; two ends of the first connecting rod which is positioned outside the support saddle are respectively hinged on the lateral pin and the suspension bracket; the guide bar and one end of the horizontal driving piece are hinged on the first connecting rod; the other end of the horizontal driving piece is connected with the guide bar; the guide bar is connected with the suspension bracket through a spherical joint; a deflection mechanism comprises a front connecting rod of the machine body, a back connecting rod of the machine body, and a deflection driving piece; the front connecting rod of the machine body and the back connecting rod of the machine body which are hinged are respectively hinged on the machine body and the vertical shaft; and the deflection driving piece arranged at the upper part of the back connecting rod of the machine body is respectively connected with the back connecting rod of the machine body and the vertical shaft. Under the situation that a tractor is fixed by trifilar suspension, the cross runout device can conveniently change the working width of the grass cutter, lead the grass cutter to deflect and tilt, and realize multiaspect cutting operation.

Description

Technical field [0001] The invention relates to a horizontal deflection device of a lawn mower, belonging to the technical field of lawn mowers for agricultural and forestry machinery. Background technique [0002] Lawn mowers are powered by machinery and are mainly used for agricultural and gardening operations. Lawn mowers of this type of structure are mounted directly behind the tractor and are usually used for pruning large areas of vegetation. However, this kind of lawn mower is a fixed structure through the three-point suspension position. The working width of the lawn mower cannot be adjusted during the operation. The working width of the lawn mower is fixed, and the working area can only be widened by the tractor. The scope of operation is relatively fixed. In addition, the cutter shaft of the lawnmower is usually set horizontally or vertically. When the lawnmower is connected to the tractor, the lawnmower cannot be tilted. Therefore, the lawnmower cannot operate on speci...

AI Technical Summary

Problems solved by technology

But this kind of lawn mower is a fixed structure through the three-point suspension position, the working width position of the lawn mower cannot be adjusted during the operation process, the working width of the lawn mower is fixed, and the working area can only be some wide tractor travel. area, the scope of work is relatively fixed

In addition, the cutter shaft of the mower is usually set horizontally or vertically. When the mower is connected to the tractor, the mower cannot be tilted. Therefore, the mower cannot work on special terrain such as ditches, bank slopes, and tree walls. The scope of use is limited

Another type of lawn mower is based on its own motor or directly driven manually, but this type of lawn mower can be controlled by manpower to operate on special terrains such as small plots, ditches, embankment slopes, and tree walls. However, the power of the lawn mower is small, and the cutting efficiency is very low, so it can only be used for the trimming of small garden lawns.
