Abstract

Use: refers to timber harvesting machines. SUMMARY OF THE INVENTION: The device comprises an arrow 2 mounted on a frame of a self-propelled chassis with the possibility of rotation by a drive in a vertical longitudinal plane. At the end of the boom 2 is mounted to rotate in a vertical plane the load gripper, rypolnenny in the form of a frame containing the lower and upper horizontal beams 6 and 5, the ends of which are connected by a vertical upright 7. The beam 5 is made telescopic the vertical plane of the latch 12 position of the timber inside the cargo capture. The latch 12 is formed of pivotally connected links that are provided with stops to limit their rotation to the outer side of the frame. The arrow 2 is mounted on the top beam 5, rigidly connected with the vertical stand. To collect the timber, the boom 2 with the load gripper is lowered to the ground and the timber along the bevel 14 is fed to the combs 15 of the lower beam 6 in the load gripper. After the first row has been laid, the telescopic section 9 of the upper beam 5 extends. Then, when section 9 is pulled out with clamp 12, the timber is pushed inside the load frame. After the bundle of timber is formed, it travels to the place of subsequent processing of 2 C. f-ly, 6 ill. (L

Description

Fig 5

The invention relates to logging machines and can be used in the forest industry for picking trees or logs in a cutting area, as well as skidding them in a semi-submerged condition at upper warehouses or loading points.

The goal is to enhance operational capabilities.

FIG. 1 shows a diagram of the device, side view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a diagram of the beginning of the collection of timber bundles; FIG. 4 is a diagram of closing the lock with the upper telescopic beam; FIG. 5 is a diagram with the complete closure of the device; in fig. 6 is a diagram of clamping packs of timber on the shield of the skidder.

The device contains a self-propelled chassis in the form of a base tractor 1, an arrow in the form of a hydraulic manipulator 2 and a load gripper 3 suspended from the boom using a hinge 4 for the possibility of rotation of the load gripper in a vertical plane.

The load gripper is made in the form of a frame containing the upper 5 and lower 6 horizontal beams connected together by a rigid vertical bar 7. A hole 8 is made on the upper horizontal beam, in the cavity of which a movable section 9 is located. It is connected by a hinge 10 to a hydraulic cylinder 11 located on the side top horizontal beam. Thus, the upper horizontal beam is made telescopic, and the hydraulic cylinder can be placed inside the movable section. At the end of the movable section 11 of the telescopic beam there is fixed a lock made in the form of links 12 with hinges 13. Moreover, the links with hinges form a multi-link structure so that the hinges 13 are located on links x 12 from inside the frame. Therefore, the ends of the links 12 become stops that limit the rotation of the links to the outer side of the frame. At the end of the lower horizontal beam, a bevel 14 is made, oriented in the direction of receiving the timber. A tooth 15 is made on the inner surface of the upper and lower load-carrying beams for fixing the timber during the formation of the pack. The frame and its structural elements interact with the timber 16,

The device works as follows.

The skidder 1 moves to the cutting area after felling trees (or after felling and pruning). Around trees or whips being harvested

the boom 2 and retracts the load gripper 3 in the direction opposite to the fixture with links 12 and hinges 13. Then the load gripper is lowered to the ground and turns

The booms 2 with respect to the skidder 1 are fed onto the timber lying on the ground. In this case, the trees or whips 16 along the bevel 14 are raised onto the lower beam 6 and are placed relative to the teeth 15.

0 After the first row of logs is laid on the lower beam, the operator switches on the hydraulic cylinder 11 and the movable section 9 of the telescopic beam extends from the frame of the load gripper. The hydraulic cylinder is then turned on for retracting, and the links 12 begin to push the trees or whips inside the gripper. The jib is fed even further onto the timber lying on the ground. If necessary, the cycle of operation of the scopic beam is repeated. During the last cycle of its movement, the load-carrying frame is completely filled with timber.

The operator then boosts 2

5 assembled pack of skidder on the shield 1. When tilting the frame, the timber is pinched inside the frame by the teeth 15. To fully clamp, just move the tractor forward

0 until the grip, tilting more and more relative to the hinge 4, will not clamp all the trees or whips in the bundle.

By eliminating the trapping of each tree or whip, the cycle of the pack pack is reduced, and due to the accelerated pulling of the pack, squeezing it on a skidder and quick shedding, the productivity is improved. Increase the front of the collection packs

Claims (2)

0 extends the technological capabilities of the application of the proposed device. Claim 1. A device for grabbing and hauling timber, containing 5 mounted on the frame of a self-propelled chassis can be rotated by a drive in a vertical longitudinal plane of the boom, the end of which is fixed to be rotated in the vertical plane of the load gripper, made in the form of a frame containing lower and upper horizontal beams, one ends of which are interconnected by a vertical stand, and at the other end of the top beam is hinged with 5 with the ability to rotate in a vertical plane the latch position of timber within the load gripper, characterized in that, in order to expand the operational capabilities, the upper beam of the gripping frame is made telescopic, and the latch is formed of hinged links that are provided with stops to limit their rotation to the outer side of the frame , and the arrow is mounted on the top beam rigidly connected to the vertical stand. 2.
