Description

Technical Field

[0001] The utility model belongs to the technical field of tree pruning, and in particular relates to a tree pruning mechanism for forestry. Background Art

[0002] Forestry refers to protecting the ecological environment and maintaining ecological balance, cultivating and protecting forests to obtain timber and other forest products, and utilizing the natural characteristics of forests to play a protective role. Tree pruning is an important maintenance measure aimed at maintaining the healthy growth and beautiful shape of trees.

[0003] At present, it is necessary to remove the excess branches on the trunk of the saplings in the early stage of growth and before transplanting. The existing removal method is generally to use manual pruning using scissors. Although the branches of the saplings are relatively thin and manual pruning is not difficult, some saplings have a large number of branches extending from the trunk, and the branches are distributed in different directions and there is also a need for pruning at high places of the trunk. This makes the use of scissors to prune the branches of the saplings a large and cumbersome task. In addition, pruning high branches makes it inconvenient for staff to operate, and there are certain disadvantages if the staff are not tall enough or have to climb high to prune.

[0004] Therefore, a tree pruning mechanism for forestry is needed to solve the problems in the prior art of a large number of branches extending from the trunk of a sapling resulting in a large pruning workload and inconvenience in pruning high branches. Utility Model Content
