Abstract

SUMMARY OF THE INVENTION: During the development of the cutting area by a logging machine, cutting, knitting and cutting of branches is carried out by a feller delimbing organ mounted on a stand. The stand has the ability to rotate relative to the boom arm in the plane passing through the boom and in the plane perpendicular to it. After cutting, the tree in a vertical position is moved in the direction opposite to the direction of movement of the machine, and a trail is made on its trail with the orientation of the tree at an angle or parallel to the longitudinal axis of the machine and resting it on the supporting device. A bough is cut when moving a tree in the direction of movement of the machine The operator’s cab, supporting device and technological equipment are mounted on a turntable. 2 sec. and 1 з п ф-л, 2 Il. cl

Description

The invention relates to the forest industry and can be used in the development of cutting areas for manipulative-type logging machines.

FIG. Figure 1 shows a forest machine at the time of the end of the knock of a tree with the tip on the track of the machine and its orientation at an angle to the longitudinal axis of the machine, plan; in fig. 2 the same, at the time of pruning when the tree is already in contact with the supporting device.

The method is carried out by a logging machine, which consists of a self-propelled chassis 1, on which platform 3 is mounted through the turntable 2. On platform 3, the operator's cab 4 is mounted, the propulsion unit 5, the manipulator arm 6, the turntable support

device 7 and its bracket 8 (rotation drive ke shown). The boom 9, controlled by a hydraulic cylinder 10, is fixed on the arm of the manipulator 6. The handle 11 is rotatably mounted on the boom 9 and is controlled by the hydraulic cylinder 12. A rotatable bracket 13 is attached to the handle, controlled via the carrier 14 by the hydraulic cylinder 15. Bracket 16 13 is connected to the stand 17 of the felling-delimbing organ on which the sawing device 18, the clamp 19, the pulling device of the roller type 20 and the delimine head 21 are mounted.

In the drawings, pos. 22 denotes the trees standing on the developed cutting area; pos. 23 - stumps of cut trees, pos. 24 - processed wood; Pos 25 - trail of a logging machine; pos 26

Example. The method is most effective for clear-cuts with the preservation of undergrowth and hardening of the porcelain truncated branches and tops.

Logging machine drives up to the wall of the forest. The operator, by controlling the boom 9 and the handle 11, guides the felling-delimbing organ against the trunk of a standing tree 22 with the stand 17 in a vertical position. After the tree is gripped with the clamp 19 and the knives of the knot head 21, the machine cuts it off. By rotating the platform 3, the tree is moved in the direction opposite to the movement of the machine, after which the operator rolls the tree onto the track 25 of the machine and then orients it relative to the machine by rotating the platform 3 and the rack 17c so that when cutting the branches of the tree to be processed, 24 ops would be on the supporting arm 7 of the support device. FIG. Figure 2 shows the processing time of the tree 24, when it was already supported on lever 7. If the need arises, the operator may use a reverse of the pulling device 20 (for example, there is not enough pulling of the pulling device or the barrel must be fed back to align the butt of the packaged whips). At the end of the pruning, the top of the tree is separated by a sawing device 18 and the whip is dropped along the track of the machine. Next to this whip, other machined machines from one side will be reset. The knot-27 felled-delimbing head trimmed on the trail can be moved along the trail of the machine to reinforce the weak points of the portage.

Claims (3)

1. The method of developing the cutting area by cutting the trees by the feller-delimbing organ of the manipulator of the logging machine, knocking down and cutting the branches, while cutting the tree is carried out in front of the machine, and cutting the branches is done in the horizontal position of the tree after fell by moving it under the manipulator while supporting to a support device, characterized in that, in order to facilitate work, increase productivity and increase the yield of industrial wood, after cutting, the tree is transferred in a vertical position to one hundred ONU opposite the movement of the machine, and it is carried out on the track of the felling followed by orientation of the tree at an angle or parallel to the longitudinal axis of the machine, thus moving a tree limbing derivative at m in the machine direction of movement. 2. A logging machine for the development of a cutting area, including a self-propelled chassis, an operator's cabin, a support device and technological equipment in the form of a manipulator with a feller-delimbing organ mounted on a stand that can be rotated relative to the boom of the manipulator, in the plane passing through the boom, and in a plane perpendicular to it, characterized in that, in order to facilitate the work of the operator and increase the productivity of the machine, the operator’s cab, support device and technological equipment mounted on a platform that is rotatable mounted on the chassis. 3. Machine pop. 2, characterized in that the support device is made in the form of a supporting lever mounted on the side of the operator’s cabin. No : uh s
