Abstract

The invention discloses a logging method and a device for the logging method. A circle of long strip tools in which the lower part is provided with a cutting edge are arranged on the stock bottom. A hydraulic device is used, so that the tools can be pressed into the roots to cut off the lateral roots of trees. Afterwards the stock is pushed to move upward. The bottom tap root is cut off, thereby the tree is uprooted. The advantages of the invention is that for the cutting tree, not only the wood pile will not be left on the ground surface, but also the tap root part under the ground surface is utilized. The device is provided with a simple structure and convenient handling, which is easy to carry when a jack is adopted as a hydraulic device.

Description

technical field [0001] The present invention relates to a logging method and its device which can maximize the utilization of timber without leaving piles on the ground, in particular to a logging method and its device which cut off the lateral roots of the tree and then lift the tree up. Background technique [0002] At present, chainsaws and chainsaws are usually used in forestry to log, which will inevitably leave a section of wood pile on the surface, causing waste, and no matter what kind of tool is used, the timber left in the lower part of the surface cannot be utilized. Contents of the invention [0003] The purpose of the present invention is to provide a logging method and its device without leaving stakes on the surface, which can maximize the utilization of timber and reduce waste. [0004] Usually, a tree needs to absorb nutrients and support its pet tree bandits through a well-developed root system. The root system generally includes two types of tap roots an...
