Description

Technical Field

[0001] The utility model relates to the technical field of greening pruning equipment, in particular to an urban greening pruning equipment. Background Technique

[0002] In the early stage, the scale of urban greening was small, and pruning work mainly relied on simple manual tools, such as scissors, saws, etc. These tools had low efficiency, high labor intensity, and it was difficult to ensure the consistency and aesthetics of the pruning effect. With the advancement of the industrial revolution, mechanical technology has developed rapidly. The emergence of internal combustion engines has provided a power source for greening pruning equipment, thus giving birth to the first generation of mechanized pruning equipment, such as handheld gasoline-powered pruning machines. The progress of electronic technology has made the control of equipment more precise and intelligent. The application of sensors can detect the pruning force, angle and position, thereby improving the pruning accuracy and safety.

[0003] When the pruning equipment prunes plants, the cut branches and debris will fly everywhere. To solve this problem, a protective device is added to the pruning equipment. The protective device can not only block the splashing branches and debris, but also prevent the operator from accidentally touching. However, the existing protective device is fixedly installed. When the pruning device needs to prune a thicker tree trunk, the protective device needs to be disassembled first before pruning operations, which reduces the use efficiency of the pruning device.
