Technical Field

The invention relates to the technical field of forestry maintenance, in particular to a directional tree-falling and cutting device.

Background

In common words: the tree cultivation method is characterized in that the tree cultivation is divided into three parts and seven parts, the survival rate of the trees after cultivation is high, whether a good effect can be achieved as soon as possible or not is judged, maintenance work is long-term careful work depending on the maintenance level, and trimming and pruning of the trees is important work for landscaping maintenance management.

In order to create a better living environment for trees in gardens, some trees with malformed and necrotic growth need to be felled. In the process of cutting trees, after a chain saw, a handsaw, an axe or the like is used for cutting the trunk of the tree, the upper part of the tree can topple along with the gradual completion of cutting, but the toppling direction has great uncertainty, the toppling direction is closely related to the cutting mode and the material of the tree, the upper end of the tree is sleeved by a rope in the conventional direction control mode, the tree is prevented from toppling towards the direction of a felling person when the tree is to be cut off, the method needs at least two persons to complete the process together, and the safety of workers pulling ropes is not guaranteed.
