Abstract

FIELD: forest industry. The purpose of the invention is to expand technological capabilities and simplify the design. The logging machine has a manipulator 3 with a working body (RO). Case 4 PO forms a storage of ground wood. In front of the RO, articulated plates 10 having knives 7 with rollers 11 and their drive are articulated from the rear part. When mixing the knives 7, the rollers 11 form a grinding device. The manipulator 3 PO is induced on the tree for its subsequent cutting with knives 7 and povala. The tree is then centered in the beveled plates 10 and pulled in by the rotating rollers 11. Thereafter, the wood enters the hopper. After filling, the accumulator is emptied into the vehicle. In addition, technological capabilities increase due to the capture of 7 lying trees with knives and their longitudinal or transverse division into parts accessible by the processing with a chopping device. 3 hp f-ly, 3 ill. @ (L S m

Description

The invention relates to the forest industry and can be used in thinning, for the compilation of low-aged and old-growth forests, as well as for the collection and shredding of illiquid parts of fallen trees and branches.

The purpose of the invention is to expand technological capabilities and simplify the design.

FIG. 1 depicts a forest machine when cutting a growing tree and then grinding

when cutting the apical part of felled trees; in fig. 3 - working tool without a felling device, general view.

The logging machine consists of a self-propelled chassis 1, on which 20 with the help of a turntable 2 mounted manipulator 3 with a working body at the end, made in the form of a body 4 with a cutting device 5 fixed in its front part, the working body can be equipped with a felling device 6 for the direction of fallen trees. The shearing device 5 is made in the form of power cutting knives 7 with a rotational drive from hydraulic cylinders 8, protected from below by U.-shaped projections 9 of body 4. Each knife 7 is equipped with vertical fencing plates 10 with bevelled 25

cutting is provided by the felling device 6 and the U-shaped protrusions 9; orbit 4. Then, the hydraulic cylinders 8 of the knives 7 and the hydraulic motors 13 of the roller 11 turn on. When the knives come down, the tree is cut and directionally falls, while the left part of the tree falls into the recess formed by the bevels of the vertical plates 10, and drawn in by the rotating rollers 11, which, when the knives 7 are brought together, form a grinding contour. The crushed wood from the rollers 11 enters the accumulator, from which periodically, as it is filled, it is unloaded into the trailer, cart or other means of transport (not shown). Large-sized trees encountered in the process corridor are cut, and their apical part is separated and sent to a chopping device. The business part of the trunk remains in the cutting area and is picked up by a skidder.

When using a machine on the selection of cut-off boughs, the operator leads the working body with rotating rollers 11 at the clumps of boughs, first flattening the knives. In this case, the knives do not participate in the work, and the rollers 11 capture the branch and crush them. If in a zone of rollers gets

front edges of the knives. 35 or a part of a large tree, which cannot be driven by rollers 11, the operator removes the worker, opens the knives 7, and then, spreads them on an oversized object, 40 pulls it out or cuts it, clearing the working area with CciMbiM. Short fragments of trees of large diameter can be split into pieces, grabbing them parallel to the fibers with knives

On the knives 7 mounted cylindrical rollers 11 with vertical radially located cutting edges. The upper support of the rollers 11 are gearboxes 12, pivotally mounted on the housing 4 coaxially with the hinges of the knives 7. When mixed, the rollers It form a grinding device, and the housing 4 serves as a storage drive

that the rollers 11 are not enough, the operator removes the worker, opens the knives 7, and then, pulling them on an oversized object, 40 pulls out or cuts it, freeing the working area for CciMbiM. Short fragments of trees of large diameter can be split into pieces, grabbing them parallel to the fibers with knives

when chopping wood pulp. At 45, For subsequent grinding,

how the thickness of the parts will be within the capabilities of the grinding device.

the waters of each roller 11 is carried out from the hydraulic motor 13 mounted on the gearbox 12 or in another well-known manner, for example by means of a chain transmission, from high-torque hydraulic motors and T..D embedded in the rolls,

Logging machine works as follows.

The operator directs with the help of a manipulator 3 cutting device 5 on a thin tree, the centering of which is relative to the power knives

cutting is provided by the felling device 6 and the Y-shaped protrusions 9; orbit 4. Then, the hydraulic cylinders 8 of the knives 7 and the hydraulic motors 13 of the roller 11 turn on. When the knives are pulled together, the tree is cut and directionally falls, while the left part of the tree falls into a notch formed by the bevels of the vertical plates 10 and tightened by the rotating rollers 11, which, when the knives 7 are brought together, form a grinding contour. The crushed wood from the rollers 11 enters the drive, from which periodically, as it is filled, it is unloaded into a trailer, cart or other vehicle (not shown). Large-sized trees encountered in the process corridor are cut, and their apical part is separated and sent to a chopping device. The business part of the trunk remains in the cutting area and is picked up by a skidder.

When using a machine on the selection of cut-off boughs, the operator leads the working body with rotating rollers 11 to clusters of boughs, preliminarily flattening the knives. In this case, the knives do not participate in the work, and the rollers 11 capture the branch and crush them. If in a zone of rollers gets

 or a part of a large tree, which cannot be driven by rollers 11, the operator removes the worker, opens the knives 7, and then, slides them onto an oversized object, pulls out or cuts it, freeing the CciMbiM working area. Short fragments of trees of large diameter can be split into pieces, grabbing them parallel to the fibers with knives

, For subsequent grinding,

how the thickness of the parts will be within the capabilities of the grinding device.

It is advisable to drive the knives 7 to perform synchronized, and the axis of the hinges of the knives 7 and rollers 11 mutually parallel.

The invention allows to extend the technological capabilities of a logging machine designed to produce shredded wood, additionally providing the possibility of cutting and directional hauling of trees, as well as capturing and

displacement of lying trees, their longitudinal and transverse division. The device has a simple design.
