SU1335463A1 - Method of working felled trees - Google Patents

Abstract

The invention relates to methods for treating felled trees and can be used for pruning branches while simultaneously producing a thin layer on thin wood intended for rafting. The goal is to improve the quality and reduce energy intensity. The method is implemented as follows. When dragging a tree through the cutting contour (working stroke), the branch is cut and at the same time only longitudinal cuts are made in the form of strips 0.02 ... 0.06 m wide to the depth of the cambial layer of wood. In case of reverse cutting circuit (idle), the prepared bands are shifted. Due to this, high-quality production of high-altitude formations is achieved without killing pre-cutting knives into business wood, and the energy intensity of the knot of a carving machine is reduced when performing the main operation - branch cutting.

Description

The invention relates to methods for treating fallen trees and can be used for pruning branches while simultaneously producing high-pitches on thin wood.

The purpose of the invention is to improve the quality and reduce energy intensity.

The method is carried out as follows.

After the trees are loaded into the machine and moved through the closed cutting contour of the delimbing head, the cutting of the branches is carried out using a grab of the pulling mechanism making the working stroke. When pruning the branches in a tree with a diameter of less than 0.14 ... 0.16 m, along with the pruning, the bark is incised longitudinally to the cambial layer of wood with a width of bark strip formed between the incisions equal to 0.02. .Oh, 06 m.

The incision of the bark is made by additional cutting elements of each of the knives of the delimbing head, which may be different, for example protruding beyond the bearing surface with incisors or discs, the outermost of which limit the zone of maximum curvature of the knives, and the distance between them corresponds to the width of the strip shifted in the subsequent bark.

When the gripper moves in the idle direction, a controlled closure is made, for example, an additional pair of gripping levers in the required areas of the treated tree and a shift in the bark in the preliminary incision zones. For this, an additional pair of gripping arms and their body can be made like knives of a delimbing head, and the shifting elements can be made structurally different.

Cutting the bark to the cambial layer of wood and the subsequent shift of the formed strips of bark also along the editor. V. Petrash

The biolayer layer is allowed to perform the splitting operation of the small-sized part of the tree without damaging the stem wood, as well as performing the main operation - pruning.

The width of the created and shifted cortical bands is 0.02 ... 0.06 m, which is optimal with

from the point of view of providing atmospheric drying of wood in preparation for its alloy, and at the same time it provides for production of at least 30% of the surface of the processed fine

wood

By pre-cutting the bark during the working stroke, high-quality bark removal without cutting the cutting bodies into commercial wood is provided, and by removing the strips of bark during idling, it becomes possible to more effectively use the energy potential of the delimbing machine when performing the main operation. Ultimately, this provides improved quality and reduced energy intensity.
