Description

(54) VEHICLE FOR TRILING TREES

one

The invention relates to the logging industry, and specifically relates to the improvement of the equipment that provides for the removal of trees from the cutting area in packs formed by feller-bundling machines.

A device for collecting and skidding trees, comprising a winch with a pull rope and a maxillary gripper controlled by hydraulic cylinders, is known. To provide skidding of a pack of trees on difficult-to-reach areas of the terrain, the device is equipped with a mechanism for detaching the pack from the maxillary grip and its subsequent pushing after overcoming the difficult-to-reach section. This mechanism is made in the form of a detachable cable loop, laid into the grooves of the maxillary grip and fitted with an automatically coupled latch in the form of special rings, laid into the notches of the ends of the clamping levers 1.

A disadvantage of the known device is the imperfection of the specified mechanism of uncoupling the pack from the grippers of the machine and the resulting difficulty in operation.

A vehicle for hauling trees is known, comprising a frame on which a winch is installed and an boom swivel by means of a power cylinder, carrying a catch, which is a traverse with hinged clamping levers attached to it, and a troso-block system, the blocks of which are fixed to the boom and the cable at one end connected to the winch 2.

The disadvantages of this vehicle are insufficient operational reliability, design complexity, and significant metal consumption.

The purpose of the invention is to increase operational reliability while simplifying the design and reducing metal consumption.

To achieve this goal, the traverse is connected to the boom by a split ball joint, and the troso-block system is equipped with additional blocks fixed on the traverse and on the sides of the clamping levers facing each other, while the traverse is bored through all these blocks. through openings traverses and the free end is fixed on the winch. FIG. 1 shows the proposed vehicle in the loaded state, side view; in fig. 2 - the same, when overcoming difficult terrain; in fig. 3 - capture when lowering it on a pack of trees; in fig. 4 - the same, with a clamped bundle of trees. The vehicle is a self-propelled chassis 1, on the frame 2 of which the boom 4 and winch 5 with cable 6 pivoted from the power cylinder 3 mounted on the boom 4 blocks 7 and 8 are mounted. At the end of the boom 4, the yoke 9 is fixed by means of a ball joint. The ball joint includes a ball pin 10 connected to the crossmember 9 and a ball bearing 12 extended from the power cylinder 11 at the end of the boom 4. To the ends of the crosshead 9 clamping levers 13 are hingedly attached with additional blocks 14 inside the jaws. In the body the crosshead 9 is provided with through holes 15 for the passage of the branches of the cable 6 and the deflecting blocks 16. The cable 6 is looped through the blocks 14, then through the blocks 16 of the cross beam 9, the blocks 7 and 8 of the boom 4 and at both ends attached to the winch drum 5.. The device works as follows. Maschina backing up to the front part of a pack of whips or trees. The winch 5 switches to idling, the boom 4 is rotated back through the cylinder 3, and the yoke 9 with the arms 13 under the action of gravitational forces is lowered onto the stack, after which the winch drive 5 is activated. The winch cable 6, turns through the blocks 14, turns the lever 13, clamping a bundle between their lower ends and a portion of the cable 6 located between the blocks 14. After clamping, the boom 4 by the power cylinder 3 is moved together with the bundle to the transport position. When the machine overcomes a difficult terrain, the cylinder 11 is turned on, the support 12 is disconnected, releasing the finger 10. The BMecte pack with the crossmember 9 is lowered onto the ground with the help of the brake of the winch 5, and the drum The winch turns on the working stroke and the pack is pulled up by the machine. At the end of the cable stroke 6, the cylinder 11 is turned on, opening the support 12, which closes after the finger 10 has entered. The end of the bundle is reset by simultaneously manipulating the boom 4 and the winch cable 6 so that the yoke 9 is removed from the bundle without tensioning the cable. The use of the proposed device for removal of wood from a cutting area allows to increase its operational reliability, simplify the design and reduce the intensity of metal. The invention The vehicle for hauling trees, containing the frame on which the winch is installed and the boom swivel through the power cylinder, carrying the grip, which is a traverse with clamping levers hinged to it, and a troso-block system, the blocks of which are fixed on the boom, and a cable is connected at one end to a winch, characterized in that, in order to increase operational reliability while simplifying the structures and reducing metal consumption, the traverse is connected to the boom the ball joint and the troso-block system are equipped with additional blocks fixed on the traverse and on the sides of the clamping levers facing each other, while the traverse has holes in it, and the cable is stored through all the blocks, fixed through the holes of the traverse and fixed to the free end on winch.
