The invention relates to forestry and agricultural machinery, in particular, to attachments for randomly hauling wood on the basis of agricultural tractors.

The purpose of the invention is to simplify cong struction and reduce metal consumption.

FIG. shown mounted attachment, side view; figure 2 - section aa in figure 1; figure 3 is a view of B and I figure 1.

On the frame of the vehicle 1, an L-shaped boom 2, 15 is hinged on which the grass 15sa 4 is hinged on the swivel mechanism 3 with the hydraulic cylinder 5 clamping the jaws of the gripper 6 mounted. In the lower part of the gripper 6, loops 10 are mounted on a horizontal plane, ki 7, placed in horizontal Swinging grip 6 around the ball plane. On the lateral outer sides of the grip 6 are fixed blocks 8, placed in a vertical transverse plane. On the boom 2 is fixed 25 additional block 9, located in the horizontal plane. Through all the blocks 7-9, a rope is stocked with the formation of a closed loop 10, forming a triangle with a top, 30 directed to the arrow 2, i.e. to the vehicle 1.

In the middle part of the throat of the gripper 6, the cable loop 10 is suspended through the ring by means of a compensating damping, with the end of the gripping, and the rope stored by the runaway spring 11. through the blocks fixed to the side

To prevent free swing and catch of catch 6, an elastic stop 12 is mounted on the L-shaped boom 2 in the direction of the tractor.

The length of the loop 10 is chosen as

the suspension of the suspension and drive towards the tractor is prevented by an elastic stopper 12.

The rope loop 10 is constantly in the compressed state due to spring I.

Claims (3)

Claims of the invention. Attachment equipment for beschekernoy. Wood hauling, containing lined on the frame of the vehicle L-shaped boom with hinged on its and the outer sides of the grip, so that, in order to simplify the construction and reduce the metal capacity, the rope is closed in a loop, and an additional block is fixed on the boom, which is surrounded by a loop of the rope, which is located in a horizontal plane. rope, stocked through all the blocks, formed a triangle with the apex facing the vehicle. way to ensure the opening of the jaws of the grip 6 at full size. The equipment works as follows. Tractor 1 drives up to a pre-shaped pack of trees in reverse or forward travel by means of the suspension piece of the pack is lifted by the hydraulic suspension of tractor 1. At the beginning of the movement, due to dragging the tail of the pack, the gripper 6, rotating around the hinge of the suspension, goes backwards towards the boom 2 and pulls the rope of the loop 10. The pulling force of tractor 1 is transmitted through the rope, the loops 10 on the gripper 6, additionally compressing it the jaws, and the rope section formed in the throat of the grip 6 presses the pack to the jaw, preventing it from slipping. The force of additional compression of the jaws and compression of the bundle is proportional to the dragging of the bundle along the ground, and also depends on the parameters of the cable projection triangle Loops 10 on a horizontal plane, Swinging a gripper 6 around a ball the end of the grip and the rope stocked through the blocks fixed to the side the suspension of the suspension and drive towards the tractor is prevented by an elastic stopper 12. The rope loop 10 is constantly in the compressed state due to spring I. Claims of the invention. Attachment equipment for beschekernoy. Wood hauling, containing lined on the frame of the vehicle L-shaped boom with hinged on its about five and the outer sides of the grip, so that, in order to simplify the construction and reduce the metal capacity, the rope is closed in a loop, and an additional block is fixed on the boom, which is surrounded by a loop of the rope, which is located in a horizontal plane. rope, stocked through all the blocks, formed a triangle with the apex facing the vehicle. 2. Attachment according to claim 1. neither By means of a hydraulic cylinder 5, it is characterized by the fact that the opening of the jaws of the gripping device 6, and the turning mechanism 3, the pickup (orientation), the gripping device 6 per package. With the help of a well-known tractor system, a mopetl rope is connected to the upper part of the gripper by a spring damper. 3. Attachment equipment according to claim. The lifting or lowering of the boom is carried out; the catch is set to the stop 6 depending on the ga-rota and the swing of the catch. ritov paches by height. After the fight4. Attachment according to claim 1, A grip of 6 on the weight of its jaw is articulated — characterized in that The hydraulic cylinder 5 and the butt grip are made maxillary. the rope loop is connected to the upper part of the grip by a spring damper. 3.
