Description

The invention relates to the forest industry and forest management and can be used on forest machines for harvesting, piling and logging.

The purpose of the invention is to increase reliability and performance.

FIG. 1 shows a manipulation circuit for a logging machine; in fig. 2 - telescopic handle with clamps; in fig. 3 is a view A of FIG. one; in fig. 4 is a section BB in FIG. 3; in fig. 5 is a sectional view BB in FIG. 2; in fig. 6 - part of the operator's cab of a logging machine with a hydraulic cylinder for driving double G-type clamps.

The logger's manipulator contains a pivot device 1, on which boom 2 with drive 3 is hinged. Boom 2 has telescopic handle 4 with its drive 5 and gripper 6 with drive 7. The telescopic handle 4 consists of an outer 8 and internal 9 sections. On the outer section 8 are mounted on the axis 10 double l-shaped locks 11 with fingers 12 and drive 13. Between the lower and upper arms of the double l-shaped locks

11, springs 14 and 15 of tension and compression, which hold the fingers 12 in the openings 16 with the sleeves 17 on the inner section 9, are installed. For a more reliable penetration of the fingers 12 into the openings 16 with the sleeves 17 on the inner section 9, shaped recesses 18 are made. To prevent spontaneous full extension of the inner section 9 from the outer section 8 at the root end of the inner section 9 in a plane perpendicular to the axis of the fingers

12 double L-shaped retainers 11, in the glass 19, end spring-loaded retainers 20 are installed, held in the retracted position by the spring 21. Glass 19 is rigidly connected to the inner section 9, which has openings 22 in which end spring-loaded retainers 20 enter, so that they are all the time in contact with the inner surface of the outer section 8. When the inner section 9 extends from the outer section 8 to the extreme position, the end spring-loaded clamps 20 enter the windows 23 with bevels 24 which are free on the walls end of outer section 25 8. Cylinder actuator 13 double T-shaped clamps 11 installed in the operator cab 26 harvester.

Manipula tor logging machine works as follows.

When working logging machines on the logging of the forest from valschika or on the shaft. forest in planted forests with small average logs, i.e. where necessary

we walk a large reach of the manipulator in order to process a greater number of trees from one side of the machine, the arrow 2 and the telescopic handle 4 occupy the position,

as indicated in FIG. 1. Next, the operator, with the aid of the driver 13 and the spring-loaded double L-shaped retainers 11, removes the fingers 12 from the openings 16 with bushings 17. The spring-loaded double L-shaped retainers rotate around the axis 10, stretching the spring 14, compressing the spring 15 and pin 12 of the holes 16. The inner section 9 with the gripper 6 and its actuator 7 under the action of their total gravity moves out of the outer section 8. When the length of the telescopic arm 4 is sufficient, the operator turns off the actuators 13 and the spring-loaded double l-shaped latches 11 nachi under the action of the springs 14 and 15, they are moved and compressed to return to their original position. The fingers 12 fall into the shaped depressions 18 and then into the holes 16 with bushings 17. The inner section 9 is rigidly fixed relative to the outer section 8 of the telescopic arm 4. The manipulator of the logging machine has a maximum reach and operates in a cycle of an articulated manipulator, t. E. The operator controls the actuators 3, 5, 7, and the turntable 1.

When using a logging machine for a logging machine on a logging track from a feller buncher, i.e. from prepared packs, or on a felling in planted forests with high average volumes of logs, i.e., where it is necessary to compare a relatively small reach of the manipulator with a significant carrying capacity, in order to put several trees in the clamping device in one cycle or to cut and put almost all trees in a pack, arrow 2 takes the position as indicated

0 in FIG. 1. The telescopic handle 4 by the actuator 5 is set to a position close to when the longitudinal axis of the boom 2 and the telescopic handle 4 are in line.

The operator using the actuator 13 and the spring-loaded double L-shaped clamps 11 removes the fingers 12 from the holes 16 with bushings 17. The inner section 9 with the gripper 6 and its actuator 7 under the action of their total gravity moves into the outer section 8. When the telescopic length the handles 4 will be reduced to the smallest possible size, the operator turns off the drive 13 and the spring-loaded double l-shaped latches 11 under the action of the springs 14 and 15 of the stretching and squeezing return to their original position. Fingers 12 enter holes 16 with bushings 17, which are located on the inside

section 9 is closer to the grip 6. The inner section 9 is rigidly fixed relative to the outer section 8 of the telescopic handle 4. The logger of the forest machine has a minimum reach and operates in a cycle of articulated manipulator, i.e. the operator controls the drives 3, 5 , 7 and a turntable 1.

The length of the telescopic handle 4 can occupy intermediate positions between those indicated in the first and second cases.

In the first case, when extending the telescopic arm 4, if the operator does not turn off the drive 13 in time, the inner section 9 does not fully extend out of the outer section 8, since in this case the end spring-loaded clamps 20, which under the action of the spring 21 all the time t for changing the shape of the inner surface of the outer section 8. If the inner section 9 extends to the maximum allowable position from the outer section 8, the end spring-loaded clamps 20 under the action of the spring 21 first enter the recesses of the bevel 24, then - in box 23 and thus fix polo

the inner section 9 relative to the outer section 8.
