Description

The invention relates to the forest industry, in particular to forest machines, and can be used for trimming knots from trees and pulling whips for subsequent bucking into assortments.

A boom of a logging machine is known, which comprises articulated links, on one of which a gripping-cutting device is also pivotally mounted, and on the other, located above the first, a gripping device, and control hydraulic cylinders, the links with a gripping-cutting and gripping devices are interconnected rigidly, while forming a forked link, part of which with the gripper is made telescopic and equipped with a drive, and the connection of the gripping-cutting and gripping devices with a forked link with filled with elastic elements (SU 1680016 F1, MKI A01G 23/08).

A delimbing-pulling device of a forestry machine is also known, including a beam on which a pulling mechanism with a movable gripper and a cable block drive system is mounted, a delimbing and receiving mechanism comprising a housing with elements for connecting to the beam and pivoting gripping arms connected to the hydraulic cylinder connected to the housing through an axis mounted on the bearings of the housing, and each housing of the delimbing and receiving mechanisms is equipped with an additional support for the axis of attachment of the hydraulic cylinder ra, while the additional support is located between the main supports and has a cross member located above the axis parallel to it and connected to the housing (SU 1676803 A1, IPC B27L 1/00).

The disadvantages of these units are the lack of the possibility of using them as manipulators for orienting and supplying wood raw materials (whips) for cutting to multi-saw installations.

The closest in technical essence to the present invention is a universal manipulator for wood raw materials, containing a swivel beam, on which a pulling mechanism is mounted, made in the form of a carriage with controlled grippers installed in the guide rails, a gripping-cutting device and a pump station with control hydraulic cylinders, the beam with the equipment is mounted on a hydraulic lift with the ability to change its height relative to the surface of the earth, and both ends the swivel beams are equipped with retractable telescopes with gripping-cutting heads (RU 2258598 C1, IPC 7 B25J 5/00, A01G 23/08).

The disadvantage of this manipulator is the inability to linearly move the rotary frame in one direction or another to increase efficiency and productivity.

The invention solves the problem of increasing productivity and expanding technological capabilities when bucking wood raw materials.

The technical result when using the invention is to increase the speed of pulling and orientation of whips and trees, increase productivity and expand technological capabilities.

The specified technical result is achieved by the fact that in the universal manipulator for wood raw materials containing a swing beam located on the hydraulic lift, on which a pulling mechanism is mounted, a gripping-cutting device of two heads mounted at the ends of the telescopes, and hydraulic equipment, according to the invention, the hydraulic lift is mounted pivotally with the possibility of turning the hydraulic cylinder in the longitudinal directions of the rotary beam, and the rod of this hydraulic cylinder in the initial position is extended halfway.

The drawing schematically shows a universal manipulator in its initial position at the time of capture of the trunk of the processed tree.

The universal manipulator for wood raw materials contains a swivel beam 1 mounted pivotally on a hydraulic lift 2. In the guides 3 of the swivel beam 1, a carriage 4 with controlled grips 5 is mounted, which is moved by winch 6 by means of traction 7 and idle 8 cables. Both ends of the swivel beam 1 are equipped with telescopic telescopes 9 and 10, on which the gripping-cutting heads 11 and 12 with upper 13 and side 14 knives are mounted.

To rotate the beam 1 in the vertical plane, the hydraulic cylinder 15 serves, the hydraulic lift 2 can also play the same role, and to move the rotary beam 1 in one direction or another along its longitudinal direction, the hydraulic cylinder 17 is installed, in which the rod 18 is half extended in the initial position. The hydraulic system of all equipment runs from the pumping station 16.

The universal manipulator for wood raw materials works as follows.

In the case when bundles of whips or trees are located on the left side of the manipulator, its initial position is such that the left telescope 9 is in the most extended position and the right telescope 10 is pushed all the way into the beam 1, while the carriage 4 should be in the extreme left position. The hydraulic cylinder 15 or the hydraulic lift 2, the swinging beam 1, bending down, leads the gripping-cutting head 11 to the next whip or tree, grabs it with the side knives 14, presses it to the upper knife 13. At the same time, the hydraulic lift 2, the whips or trees can be caught for processing from packs and stacks any height and capacity. Under the action of the hydraulic cylinder 17, by extending the rod 18 for the entire length, the swing beam 1 extends horizontally to the left, increasing the orientation zone of the carriage 4 with controlled grippers 5. Then, by moving the telescope 9 to the right side, the gripping-cutting head 11 with the tree, moving in the same direction, transmits the latter carriage 4. After the controlled grips 5 of the carriage 4 grab the tree, all the knives (13 and 14) of the gripping-cutting head 11 release it, but support it. The telescope 9 with a gripping-cutting head 11 moves to the left to its original position, and the carriage 4 with a tree is pulled along the guides 3 of the beam 1 with a winch 6 along the guides 3 to the second (right) gripping-cutting head 12. Moreover, if the tree is with branches, they are trimmed with knives 13 and 14 of the gripping-cutting head 11. At this time, the tree, clamped by the knives 13 and 14 of the gripping-cutting head 12, is pulled further to the right by the extension of the telescope 10, and the freed carriage 4 with the idle cable 8 of the winch 6 returns to the left to its original position . When the telescope 10 reaches its rightmost position (extends to its full length), the left telescope 9 with the knives 13 and 14 of the gripping-cutting head 11 clamped on the tree starts to move to the right, and the telescope 10 at this time with the opened knives 13 and 14 of the gripping-cutting head 12 is returned to the left in its original position. Under the action of the hydraulic cylinder 17, pulling the rod 18 all the way, the swing beam 1 extends horizontally to the right, increasing the range of the carriage 4 with controlled grippers 5 and the gripping-cutting head 12. Then, the process of dragging the whip or tree is repeated with the orientation along the saws of the cutting unit.

In the case when packs of whips or trees are located on the right side of the manipulator, its initial position is such that the right telescope 10 is at the maximum extended position and the left telescope 9 is pushed fully into the swing beam 1, while the carriage 4 should be in extreme right position.

The control of all the manipulator equipment in automatic mode with the help of a pumping station is carried out by the operator of the cutting unit, in which this universal stationary manipulator is installed.

The introduction of the proposed manipulator, universal for wood raw materials, will significantly increase productivity by continuously dragging the whips or trees, increasing the range of the manipulator in the longitudinal direction and orienting the whips or trees along the saws of the cutting unit. All this will expand technological capabilities and increase the efficiency of the manipulator.
