Pruning and cutting device for branches and leaves at high positions of garden trees

Abstract

The invention discloses a pruning and cutting device for high branches and leaves of garden trees, and belongs to the technical field of tree branch and leaf pruning. The pruning and cutting device for high branches and leaves of garden trees comprises a moving plate, a pruning assembly is arranged below a limiting rod, an electric control hydraulic rod is fixedly arranged in the middle of the inner side of a supporting frame through a screw, the piston end of the electric control hydraulic rod penetrates through the inner wall of the supporting frame to extend to the outside and is fixedly provided with a U-shaped block, the outer side of the supporting frame is symmetrically and rotationally connected to two supporting rods through hinge pins, pruning knives are connected to the outer end of the connecting rod in a welding mode, the outer side of the U-shaped block is provided with an adjusting hand wheel, the threaded end of the adjusting hand wheel is sleeved with a spring B, through close cooperation of the structures, the device can prune the branches and leaves of the trees through annular movement of the multiple pruning knives, the working efficiency is improved, the pruning can be completed at a time, therefore, the branches and leaves at the high positions of the trees can form a uniform appearance, the uneven condition is avoided, and the trees are more attractive.

Description

technical field [0001] The invention relates to the technical field of tree branch and leaf pruning, in particular to a device for trimming and cutting off branches and leaves of garden trees at high places. Background technique [0002] The beautiful natural environment and recreational environment created by using engineering technology and artistic means in a certain area by transforming the terrain, planting trees and flowers, building buildings and arranging garden roads are called gardens. It is unique in Chinese Han architecture, and the one with great achievements is the classical garden architecture. Tree pruning is an important part of garden maintenance and management. It has the following effects on tree pruning: improving the survival rate of garden trees, adjusting tree vigor, controlling growth, removing bad and keeping good, improving light transmission conditions, enhancing photosynthesis, reducing Pests and diseases, realize the beautification and shaping ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned device has many beneficial effects, the following problems still exist: the above-mentioned devices all use a cutter to prune individual branches and leaves, which is not only inefficient, but also a single manual pruning cannot make it form a uniform shape, resulting in uneven appearance. It affects the beauty of the garden, and the workload is huge. In addition, in other existing tree pruning devices, such as CN202021779620, tree pruning in different ranges or different radii is achieved through elevating rods, but it requires manual rotation to perform circular pruning. In addition, the existing The pruning device cannot realize the contour cutting of different shapes in the vertical direction of the branches, and is not suitable for pruning operations that require garden landscape areas. In view of this, we propose a cutting device for pruning branches and leaves at high places in garden trees
