(54) DEVICE FOR TRIGGER STRIPS

I

The invention relates to a locking device mounted on a boom of a self-propelled chassis, and can be used in the forest industry.

A device for rooting stumps, mounted on a boom of a self-propelled chassis and including a hinged rigid structure with a working body and a jaw grip with a drive, is known.

However, this device has a low productivity due to the time spent on cutting the lateral roots and the lack of reliable extraction of the mon.

It is also known a device for rooting stumps, which includes a frame with a driving working body made in the form of a wedge, a support for the pin and the mechanism of jerking | j2j.

A disadvantage of the known device is the low reliability of the process of uprooting.

The purpose of the invention is to increase the reliability of the rooting process.

The goal is achieved by the fact that the lower part of the frame is made with stops, and the uprooting mechanism is made in the form of a tong clamp, the jaws of which are hinged on the frame, with the base plate mounted on the wedge-shaped working body.

The stump rooting device comprises a frame made in the form of a hydraulic cylinder I, the longitudinal axis of which coincides with the vertical axis of clearing and which is provided with two jaws 2 arranged to each other at an angle of 180, hinged on brackets 3 rigidly mounted on the cylinder I case. For the upper part of the hydraulic head I case, the uplifter is suspended on the boom of the crane shl mannul tortora. Between the brackets 3 and the jaws 2, the hydraulic struts 4 rotate chests 2 are hingedly mounted. At the end of the rod of the hydraulic cylinder I there is a rigidly fixed wedge-shaped working body b with a base plate 7, the cutting edge of which is perpendicular to the plane of the jaws 2 of the gripper. The device works as follows. An upholstery arm is mounted above the stump so that the latter is approximately on the longitudinal axis of the hydraulic cylinder 1. And the wedge-shaped working body 6 lowers the cutting edge to the mon surface along its diametrical section, and the stops 5 touch the surface of the mon. wherein they do not touch the surface of the mon.) Then the working fluid enters the hydraulic cylinders 4 turns of the jaws and the latter are set up under the chain. After this, the working fluid enters the cavity of the hydraulic cylinder I. The rod of this hydraulic cylinder with a wedge-shaped working body b is lowered at the end and the working body acts on the stump with a cutting edge, splitting and penetrating into it. Further, as the working sphg b deepens, under the influence of the hydraulic cylinder I rod into the stump, the working body 6 with the base plate 7 reaches the ground surface and with further movement down the hydraulic cylinder rod I acts on the ground, due to which the extraction of the mon with the root system occurs. As the working device 6 deepens into the stump, the latter splits, the halves move apart, affecting the lateral roots and the adjacent ground, the latter loosens and 894 weakens the bonds of the lateral roots with the ground, due to which less effort is required to extract the mon Then, the stump of the arm of the manipulator is transferred to the body of the vehicle or a pile. After that, the working fluid is supplied to the opposite cavity of the hydraulic cylinder I. The stem of this hygrocylinder with a wedge-shaped working body under It comes up, releasing the stump. The stops 5 serve to prevent the movement of the mon when the rod is drawn in with the working body b in the cylinder. After the jaws 2 are compressed, the device is again ready for operation. Thus, the proposed device is more efficient than and known. and the use of splitting mon allows to increase productivity and reliability when extracting mon. The invention of the device stubbing stumps, including a frame with a natural working body, made in the form of a wedge, support plate and a shorter mechanism Ani of g l and chayuschees in that, in order to increase the reliability of the clearing of the process, the lower part of the frame is provided with abutments and grubbing mechanism - a tong, which jaw scharnirno secured to the frame, wherein the support plate is mounted on a wedge-shaped working body.
