Description

The invention relates to the forest industry and can be used to carry out timber hauling operations.

The purpose of the invention is to simplify the design and improve performance.

Figure 1 shows a logging machine with a dp chopping machine for tree sowing, a general view; in Figure 2, the gripping structure} in FIG. 3 — a chocking-fixing device} in FIG. 4 — section AA in FIG. 3, FIG. 3 — self-releasing retainer} of FIG. 6 — locking device.

The device consists of a self-propelled chassis 1, a manipulator 2, a gripper 3. The gripper consists of castors 4 and 5. The spring 6 holds the gripper in the open position. It serves to close the gripper. three 7.1

At the ends of castorsbeans 4 and 5 of the grip 3 “fixed. choker ring 8 and carabiner 9. On the carbine 9, the end of the choker cable 10, which is passed through the choker ring 8, is fixed. A spring 14 is attached to the castors in the slots 11. It is necessary for ejection from | nests of the choker ring 8 and carbine 9.

The carabiner 9 is provided with a retainer 15, which is held in the closed position by a spring 16. The carabiner and choker ring for mounting in the castors nests have a holder 17 with a figured retaining channel 18, which is filled in the form of grooves 19-22 different in depth to move the spring stopper , and only in one direction. The grooves 20 and 21 have a bend 23, necessary for fixing the spring stopper - 12, carabiner and choker ring

have a web 24 that separates the holes for the cable and for the closure. To connect the skidding cable 25 with the choker cable U

5 serves as a stop ring 26.

The device works as follows.

The choker ring 8 and the carabiner 9 are inserted into the slots 11 of the castors of the 10-grip 3. The stopper 12 enters the groove 18. Moving along the groove 19, the depth of which is gradually reduced, the spring stopper 12 is compressed. Once in the deeper groove 20,

15, the stopper 12 expands and can only move along the groove 20. While advancing along the groove 20, the stopper 12 falls into a deeper groove 21 and is fixed in bend 23, held by the carabiner and choker ring in the grip brackets.

The gripper 3 with the cable 10 secured therein is delivered to the felled tree by the manipulator 2. After

25 pulling the grip onto the tree pull the cable to close the grip 7 and, overcoming the tension of the spring 6, close the grip. When the grip hooks are closed, the choker cable 10 covers the tree with a loop, the choker ring 8 moves the latch 15, which, returning under the action of the spring 16 to its original position, locks the choker ring in the carbine 9. The choker ring 8 presses on the jumper 24 of the carbine, which in its all pressure on chokernoy ring. The choker ring 8 and the carbine 9 compress the spring 14. The spring stopper 12, moving along the groove 21, falls into the groove 22.

After the carbine is closed, the cable to close the grip 7 is loosened and the grip is opened by the action of the spring 6. The stopper 12, moving along the groove 22, comes out of the holder,

A skid cable 23 is pulled in and a loop is drawn around the tree. The tree is shot down to the tractor 1. The load-less manipulator 2 is assembled to its original position.
