Abstract

FIELD: forestry, in particular, swamping of old cutover areas.

SUBSTANCE: method involves forming small-sized growth windrows by means of bush cutter, which effectuates shuttle motions along transverse strips of cutover area and turns at area boundaries; providing uprooting over the entire cutover area by means of rooter-collector, which effectuates reciprocating motions along longitudinal strips, perpendicular to growth windrow axes to move rooted stumps and growth windrows into single lumber waste windrow, while advancing along the latter from distal boundary to proximal boundary of cutover area (this advancement of rooter-collector may be done from proximal boundary to distal boundary of cutover area as well). After rooter-collector reaches proximal boundary of cutover area, it moves to other side of single lumber waste windrow and, by effectuating similar motions along longitudinal strips beginning from proximal boundary of cutover area, forms second single lumber waste windrow by advancing to distal boundary of cutover area, the cycle being repeated multiple times.

EFFECT: reduced number of lumbar waste windows, increased area for forest crops, and provision for operation of tillage machines.

Description

The present invention relates to forestry and can be used for clearing areas of old clearings.

There is a method of continuous clearing the area of the old felling for forest crops with knife-type brush cutters, forming small shafts of bushes and small forests (hereafter, overgrown) on both sides of the brush cutter mainly by shuttle movement along the felling area (M. Metalnikov Forestry machines, 1991, s .12).

The disadvantages of this method of clearing the felling area is the formation of a large number of small shafts of overgrowth and the presence of stumps in the felling area, which excludes the use of forestry tools for tillage for forest crops.

There is a method of mechanized continuous clearing of the cutting area by the eradicator-gatherer, forming shafts of logging waste (stumps, roots, chopping residues, dead wood, etc.) left for decay (Girlev DM, etc. Manual for forest restoration in the coniferous zone broad-leaved species of the European part of the RSFSR. - M., 1987, p. 11).

The disadvantage of this method of mechanized continuous clearing of the cutting area under forest crops is the peeling of the upper fertile soil layer and its mixing together with logging waste, as a result of which logging waste shafts have a significant amount of soil impurities, which excludes the possibility of burning them.

The aim of the invention is to reduce the number of shafts of logging waste, increase the area of felling for forest crops and create the possibility of forestry implements working on the soil.

This goal is achieved by using brush cutters to cut the overgrowth and the stubber-collector to root out stumps and collect them into shafts.

The novelty lies in the fact that at first the brush cutter forms small shafts of overgrown, then the uproar-gatherer shifts the stubs uprooted by it and the overgrown shafts into common large shafts of logging waste.

The drawing shows a process diagram of the operation of the machines according to the proposed method of clearing the felling area for forest crops.

The operation of machines by this method is as follows. First, the brush cutter 1 by shuttle along the transverse strips 2 of the cutting area with turns at the borders of the cutting cuts the shoot and forms small shafts of the shoot 3 in the entire cutting area (in the drawing, the movement of the brush cutter is shown by vertical arrows). After cutting the shoots, the uprooter 4 picks up stumps, and then reciprocating along the longitudinal strips 5 perpendicular to the axes of the shafts of the shoots 3 shifts the stumps uprooted by them and the shafts of the shoots 3 into the common shaft of the logging waste 6, moving along it from the far boundary to the near cutting edge (this movement of the eradicator-gatherer 4 is also possible from the near boundary to the far boundary of the cutting). After that, the tiller-collector 4 moves to the nearest boundary strip 5 on the other side of the common shaft 6 and forms the second common shaft 6 of logging waste with similar movements, moving along it from the near border to the far boundary of the cutting area, and so the cycle repeats (the tiller 4 the drawing is shown by horizontal arrows).

This method of clearing the area of the old felling makes it possible to reduce the number of overgrown shafts and increase the area of felling for forest crops.

Claims (1)

The method of mechanized continuous clearing of the felling area for forest crops, including the formation of shrubbery shafts by a brush cutter by shuttle movement along the felling area with turns at the cutting edges and uprooting of stumps by the eradicator-gatherer over the entire felling area, characterized in that the eradicator-gatherer is perpendicular to the spruce shifts stumps and spruce shafts into common shafts of logging waste, moving along common shafts from one border of the felling area to another border with a spread at the borders of cutting down.
