Abstract

FIELD: forestry.

SUBSTANCE: invention relates to forestry, in particular, to improvement cutting in young forests with a closed timber stand and a narrow width of the haul route. The method for felling trees in young forests includes felling the picked trees, forming a package of trees, and hauling to the loading point. The trees to be cut are felled perpendicular to the longitudinal axis of the haul route onto a baffle plate secured on the boom of the hydraulic manipulator of the logging tractor, configured to be tilted and gradually lowered in the vertical plane on interaction with a cut tree. The latter slides along the inclined plate under its own weight and is laid along the longitudinal axis of the haul route by means of a hydraulic manipulator. The cut trees are then formed into a package using a hauling winch installed on the blade of the same logging tractor, followed by haulage to the loading point.

EFFECT: use of the proposed method for felling trees in young forests with a closed timber stand and a narrow width of the haul route allows felling trees without damaging the neighbouring trees and trees in the nearby rows.

Description

The invention relates to forestry, in particular to thinning in young forests with a closed forest stand and a narrow width of the skid trail.

A known method of felling trees in an apiary when developing a cutting area using the narrow apiary method, which consists in the fact that the trees to be cut are felled at an angle to the axis of the skidding portage using gasoline-powered saws (Kochegarov V.G., Bit Yu.A., Menshikov V.N. Technology and machines of logging operations: a textbook for universities - M .: Lesnaya promyshlennost, 1990. - 392 pp. [p. 103, Fig. 3.14a]).

The disadvantage of this method is that with a narrow width of the skid trail, damage occurs to neighboring trees, especially in a closed forest stand and trees of nearby rows.

The closest is the method of felling trees to be felled by commercially available VPM, which allow you to fell trees along the logging trail without damaging neighboring trees and trees of nearby rows (Technology and logging machines. Shkirya T.M. - Lvov: Vyscha shk. Publishing house at Lvov, University, 1988. - 264 p. [p. 232 fig. 11.6]).

The disadvantage of this method of felling trees, especially with a narrow width of the skidding trail, is that the width of the VPM is greater than the width of the skidding trail, and for skidding trees, a skidder is also required, the width of which is also greater than the width of the skidding trail.

The technical result is the development of a method for felling trees in young stands with a closed forest stand and a narrow width of the skid trail without damaging neighboring trees and trees of nearby rows.

The technical result is achieved by the fact that the method of felling trees in young forests, including the felling of trees set aside for felling, the formation of a package of trees, hauling to a loading point, according to the invention, the trees to be felled are felled perpendicular to the longitudinal axis of the skidding portage on a chipper mounted on a hydraulic boom. of a logging tractor manipulator with the possibility of its tilting and gradual lowering in a vertical plane when interacting with a sawn tree, which slides along the inclined chipper under its own weight and fits along the longitudinal axis of the skidding trail using a hydraulic manipulator, after which the cut trees are formed into a package using a skidder winches installed on the blade of the same logging tractor with subsequent hauling to the loading point.

The invention is illustrated by drawings.

In FIG. 1 - a logging tractor is presented (general view), in Fig. 2 - a method of felling trees using a gasoline-powered saw and a logging tractor.

The proposed method includes a small-sized logging tractor 1, containing a hydraulic manipulator 2, with a chipper 3, a blade 4 with a skidding winch 5, a feller 6 with a gasoline-powered saw 7 and trees 8 to be cut and skidding portage 9.

The method of felling trees is as follows. A small-sized logging tractor 1 drives up to a tree 8 to be cut, a feller 6 approaches the same tree and, using a gasoline-powered saw 7, cuts the tree 8 perpendicular to the skidding trail 9 onto the bump stop 3 of a small-sized logging tractor 1, which, when interacting with the sawn tree 8, gradually descends in a vertical plane along the skidding portage, using a hydraulic manipulator 2, laying the tree 8 along the longitudinal axis of the skidding portage 9. After felling the trees, the tractor turns around and, using the skidding winch 5 installed on the blade 4, forms a package of fallen trees 8 with their subsequent skidding to the loading point .

As a result of using the proposed method, felling trees in young stands with a closed forest stand and a narrow width of the skid trail allows felling trees without damaging neighboring trees and trees of nearby rows.

Claims (1)

A method for felling trees in young stands, including felling trees set aside for felling, forming a package of trees, skidding to a loading point, characterized in that the trees to be felled are felled perpendicular to the longitudinal axis of the skidding trail on a chipper fixed on the boom of a hydraulic manipulator of a logging tractor with the possibility its inclination and gradual lowering in a vertical plane when interacting with a sawn tree, which slides along the inclined fender under the action of its own weight and is laid along the longitudinal axis of the skidding trail using a hydraulic manipulator, after which the sawn trees are formed into a package using a skidding winch installed on the dump the same logging tractor, followed by hauling to a loading point.
