Description

Tree felling anti-tilting device and method

Technical Field

The application relates to the technical field of tree felling, and particularly discloses a tree felling tilting prevention device and a tree felling method.

Background

Precious trees refer to ancient tree names with great historic commemorative significance, scientific research value or long-term age determined by forestry authorities or other departments above province level, precious trees forbidden by the country and limited to export, and trees listed in the national important protection wild plant directory.

In the planting process of precious trees, the situation that the trees grow too densely easily occurs, at the moment, a large amount of sunlight is covered by the relatively high tree branches, so that the growth of other new trees is influenced, at the moment, the trees with large diameters meeting the cutting requirement are needed to be cut, and the situation that the trees are too densely occurs is reduced, but because the trees meeting the cutting requirement are relatively high, if the trees are directly cut, the cut trees can be directly poured onto the branches of saplings or other trees, so that the situation that the saplings and the trees which do not need to be cut are damaged is caused, and the places where the precious trees are planted are not cut in batches, so that large anti-toppling cutting equipment cannot enter the woodland operation, and the inventor has the problem that the cut trees are prevented from being inverted and the cut method thereof.
