Abstract

FIELD: logging operations.

SUBSTANCE: invention can be used for harvesting wood in cutting areas with a uniform distribution of undergrowth. The method for developing cutting areas is carried out as follows. With a harvester, which approaches the forest wall at the point of the trail, the cutting of the trail in the apiary is carried out by felling trees located within the boundaries of the trail onto the forest wall in the direction of the harvester, followed by pulling the trees towards themselves, pulling their trunks through the delimbing knives of the harvester head and laying them along the right and left edges of the dragging of logs, and logging residues on the trail. After passing the trail with a harvester, which then enters the next trail to cut it, or after turning around, half-blocks located along the drag are developed, trees growing in the half-blocks are felled with their tops on the trail. The butt part of the felled trees is lifted by the harvester manipulator and carried out onto the trail. After this, the harvester inside the trail processes the felled trees (delimbing and cross-cutting) and cross-cutting the logs laid along the trail, dividing the cut assortments into three groups (long, medium and short) on the right and left along the edges of the trail and piles of logging residues on the trail.

EFFECT: reducing the damage to undergrowth when developing cutting areas with its uniform location.

Description

The invention relates to logging operations and can be used for harvesting wood in cutting areas with a uniform distribution of undergrowth.

There is a known method for developing logging areas (Matveiko A.P., Fedorenchik A.S. Technology and machines for logging work. Minsk, 2002. P. 312-313), including cutting the trail in the apiary and developing half-apiaries using a harvester by felling trees and processing the felled trees, including pruning and bucking, dividing sawn assortments into groups, storing them on the right and left along the edges of the trail, and logging residues on the trail. The cutting of the trail in the apiary and the development of half-apiaries are carried out simultaneously, while the felling of trees, as well as pruning and bucking, is carried out perpendicular to the drag. The sawn assortments are divided into two groups: long-length and short-length. Accepted as a prototype.

The disadvantage of this method is the high damage to the undergrowth when it is evenly distributed in the cutting area, since in the process of cutting the trail in the apiary and developing half-apiaries, the harvester cuts down the trees perpendicular to the trail, and then pulls their trunks through the delimbing knives of the harvester head, resulting in the contact area of the tree crowns with adolescence it turns out to be very large.

The problem to be solved by the invention is to reduce the damage to undergrowth during the development of cutting areas with its uniform location.

This is achieved by the fact that in the method of developing cutting areas, which includes cutting a trail in an apiary and developing half-apiaries using a harvester by felling trees and processing felled trees, including pruning and bucking, dividing the cut assortments into groups, storing them on the right and left along the edges of the trail, and the logging residues - on the trail, according to the invention, are first cut in the apiary trail by felling trees located within the boundaries of the trail onto the forest wall in the direction of the harvester, followed by pulling them towards themselves, pulling the trunks through the delimbing knives of the harvester head and laying them along the right and the left edge of the trail of the logs, after which half-apiaries are developed, while the felling of trees growing in the half-apiaries is carried out with their tops on the drag, and the butt part of the felled trees is lifted by the harvester manipulator and carried to the drag, after which the felled trees are processed inside the drag together with bucking of the trees laid along dragging the whips.

In fig. 1 shows a diagram of the method for developing cutting areas when cutting a trail in an apiary; in fig. 2 – the same, when developing half-apiaries.

In fig. shown: harvester 1, drag 2, trees 3 located within the borders of drag 2, logs 4 laid along the right and left edges of drag 2, logging residues 5 laid on drag 2, trees 6 growing in half-apiaries, felled trees 7, which carried out from the half-apiaries to the drag 2, undergrowth 8 growing in the half-apiaries, groups of cut assortments 9.

The method for developing cutting areas is carried out as follows.

Harvester 1, which approaches the forest wall at the point of drag 2, cuts the drag 2 in the apiary by felling trees 3 located within the boundaries of the drag 2 onto the forest wall in the direction of the harvester 1, followed by pulling the trees 3 towards itself, pulling their trunks through delimbing knives of the harvester head and laying logging residues 5 along the right and left edges of the drag 2, and on the drag 2 - logging residues 5 (Fig. 1). After the passage of the drag 2 by the harvester 1, which then enters the target of the next drag to cut it or, after turning around, begins to develop half-apiaries located along the drag 2 (Fig. 2), trees 6 growing in the half-apiaries are felled with their tops on the drag 2, and the butt Some of the felled trees 7 are lifted by the harvester manipulator 1 and carried to the drag 2, resulting in minimal impact on the undergrowth 8 growing in the half-apiaries. After this, the harvester 1 inside the drag 2 processes the felled trees 7 (pruning and bucking) and bucking the logs 4 laid along the drag 2 with the division of sawed assortments 9 into three groups (long, medium and short) on the right and left along the edges of the drag 2 and the piles logging residues 5 on the trail 2, while the operations for processing felled trees 7 and logs 4 do not have an impact on the undergrowth 8 growing in the half-apiaries.

The use of the claimed invention makes it possible to reduce the damage to undergrowth when developing cutting areas with its uniform location.
