Abstract

The invention relates to a self-propelled green hedge trimmer and a use method. The problems that an existing green hedge trimmer is not flexible in trimming knife operation angle adjustment and inconvenient to operate, and has difficulty in trimming beveled green hedges and landscape trees with certain height are solved. The angle, relative to the base, of a long arm rotating arm is adjusted through telescoping of the first stage hydraulic cylinder; the height and angle, relative to the long arm rotating arm, of a middle arm rotating arm is adjusted through telescoping of a second stage hydraulic cylinder; a sleeve is fixedly connected to the other end of the middle arm rotating arm, a fan-shaped gear is installed on the side wall of the middle arm rotating arm, the bottom of a cylinder body of a third stage hydraulic cylinder is hinged to the middle arm rotating arm, the tail end of a piston rod of the third hydraulic cylinder is hinged to the fan-shaped gear, the head end of a shortarm overturning arm is installed on the sleeve, and a saw blade is installed at the tail end of the short arm overturning arm; overturning of the short arm overturning arm is achieved through telescoping of the third stage hydraulic cylinder. Accordingly, the green hedge can be trimmed at different slopes and certain height.

Description

technical field [0001] The invention relates to a hedge trimmer and a use method thereof. Background technique [0002] With the continuous expansion of the scale of cities in our country, improving the living environment of residents has become an indispensable part. At present, there are two main methods for pruning urban green seedlings in my country. One is manual pruning, which is labor-intensive and low-efficiency. At the same time, workers are exposed to roads, which poses a certain risk to personal safety. The 2nd, adopt hedge trimming car to trim hedge, but existing hedge trimming car can only be trimmed to the top surface or the side of hedge, and can't be trimmed to the hedge on the slope and the afforestation tree of certain height. Contents of the invention [0003] The purpose of the present invention is to provide a self-propelled hedge trimmer and its use method to solve the inflexible adjustment of the pruning knife operating angle and inconvenient operat...
