A tree-climbing mechanism for a garden pruning robot

Abstract

The invention relates to a tree climbing mechanism of a garden pruning robot, which comprises a pipe frame capable of sleeving a tree trunk in a penetrating manner, wherein a tree climbing mechanism is arranged on the pipe frame; the tree climbing mechanism comprises a plurality of groups of climbing rollers; the climbing rollers are arranged on the inner sides of half pipe frames of the pipe frame; a wheel core of the climbing roller and a pipe core of the pipe frame are arranged at an included angle; a power mechanism drives the climbing rollers to rotate; and a deflection angle is formed between the wheel core of the tree climbing roller and the pipe core of the pipe frame, so that when the tree climbing rollers abut against the tree trunk, the pipe frame can climb upwards along the trunk, and the climbing of the pipe frame located on the trunk is in a spiral upward state. In addition, blocking arms can abut against branches of the tree, the tree climbing rollers vertically move upwards when the blocking arms abut against the branches, so that sawing operation on the branches is achieved.

[0002] For artificially planted mountain forests with economic effects, in order to improve the growth speed and quality of trees, it is necessary to carry out necessary pruning operations on trees in late winter and early spring. The so-called pruning actually means removing the branches on the trunk. Trunks, especially for pine and poplar trees, removing the branches of the main trunk can effectively ensure the straight growth of the trees, so that the straightness and roundness of the trees are greatly improved. Currently, the branches of the trees are being removed There are also many removal robots. However, most of the existing robots are straight up and down to realize the removal operation of the trunk and branches, and the panel saws used by the existing pruning robots for sawing branches are mostly arranged for branches. When the robot moves to the side of the vertical branch, the pruning robot rotates, and the chain saw rotating on one side of the panel saw implements the vertical sawing operation. Under the action of the panel saw, it always makes the panel saw and the branch rigidly contact, which not only affects the service life of the panel saw, but when the panel saw implements vertical sawing operation, it can only cut the branches close to the main trunk. The remaining part of the trunk remains on the main trunk, and the branches are completely removed, so the quality of tree pruning cannot be guaranteed. When the trees grow later, long branches will still sprout from the removed branches, which will have a certain impact on the straightness and roundness of the tree. , and when the panel saw cuts off the branches, it is easy to cause damage to the bark due to the bending of the tree and the extension of the branches.
