Automatic pruner for greening seedlings

Abstract

The invention provides an automatic pruner for greening seedlings. The automatic pruner comprises a mounting frame, a lifting tree climbing device, a branch pruning device and a controller, wherein the lifting tree climbing device and the branch pruning device are mounted on the mounting frame; the lifting tree climbing device is used for enabling the whole tree climbing pruner to be clamped outside a trunk of a tree to be pruned and can also pull the whole tree climbing pruner to carry out ascending or descending motion in the axial direction of the trunk of the tree; the branch pruning device is used for pruning branches on the trunk of the tree as required; and the controller is used for controlling motors in the lifting tree climbing device and the branch pruning device to run. The automatic pruner can be coaxially mounted outside the trunk of the tree only by the assistance of a worker, and the branches of the tree can be cut off and pruned only by the worker operating the controller to control the motors in the lifting tree climbing device and the branch pruning device to run in a subsequent process, so that the labor intensity of the worker is reduced, and the safety of theworker is further greatly improved.

Description

technical field [0001] The invention relates to the field of greening, in particular to a device for repairing tree branches. Background technique [0002] Trees often need to be pruned to the branches of trees during the growth process. Existing branch pruning is usually realized by pruning shears or reciprocating electric pruners. Pruning scissors are suitable for thinner branches. When pruning, an electric pruner is needed. When pruning thick branches on taller trees, a lifting platform is needed, and then the operator stands on the lifting platform and holds the electric pruning device for pruning. However, electric pruning The quality of the pruner is generally heavy, and it is easy to feel fatigue and reduce the efficiency if it is held for a long time. If the electric pruner is directly fixed on the lifting platform, the direction of the electric pruner cannot be changed. It can only be trimmed once and then readjusted. The position of the electric pruner is fixed, a...

[0002] Trees often need to be pruned to the branches of trees during the growth process. Existing branch pruning is usually realized by pruning shears or reciprocating electric pruners. Pruning scissors are suitable for thinner branches. When pruning, an electric pruner is needed. When pruning thick branches on taller trees, a lifting platform is needed, and then the operator stands on the lifting platform and holds the electric pruning device for pruning. However, electric pruning The quality of the pruner is generally heavy, and it is easy to feel fatigue and reduce the efficiency if it is held for a long time. If the electric pruner is directly fixed on the lifting platform, the direction of the electric pruner cannot be changed. It can only be trimmed once and then readjusted. The position of the electric pruner is fixed, and when pruning the next place, it needs to be rewritten, disassembled, adjusted and fixed again. It is very troublesome to use. Therefore, it is necessary for the present invention to propose a tree pruning device, which only needs the assistance of staff The branch repairing machine can be installed coaxially outside the trunk of the tree. The subsequent tree climbing and branch cutting repair process can be realized only by the staff operating the controller to control the operation of the motor inside the lifting tree climbing device and the branch repairing device. The cutting and repairing of tree branches not only reduces the labor intensity of the staff, but also greatly improves the safety of the staff
