Description

A device for the stump removal includes a power frame with hydraulic cylinders, a cargo frame with jaw gripping and a vibrator with an anvil.

The purpose of the invention is to improve the efficiency in the work of the lifter.

This is achieved by the fact that the load frame is made with a plate fixed with the possibility of reciprocating movement in a vertical plane, and the vibrator is rigidly mounted on this plate. The slab is made with a guide rod, on the end of which the head is mounted, and the anvil is mounted on a beam, with the help of which the lower brackets of the load frame are connected to the jaw of the grip.

The drawing shows the proposed device, a general view.

The force frame / device is made in the form of an arch with hydrotschipdramp 2 fixed at its ends, the free ends of the rods end with hinged supports tl In the upper part of the arch, the suspension bracket 4 is mounted to the loader arm, the load frame 5 encloses the arch with closed arches attached to the loader boom, the arch of the loader, and the cargo frame 5 encloses the arch with clocks attached to the loader arch with the arch of the loader; fingers 7, which also serve to secure the jaws 5 of the grip. The opening and closing of the jaws of the grip is made by means of hydrocipdles 5. The spring suspension of the load frame consists of a spring 10 of greater rigidity located between the cup / cargo frame and glass / 2 of the force frame and the spring /.5 small stiffness between the anvil 6 and the arch. Spring tension adjusts with iomond nuts / - /. The vibratory hammer is made in BC; de eccentric vibrator / 5. a rigidly mounted plate / b with a guide rod / 7, which passes through the guide sleeves of the glasses 12.

The device for frozen frost works as follows.

After installing the device over the stump of the hydraulic cylinder 9, the jaws of the bite are closed, holding the stump securely. Then, the driver and the hydraulic jack jacks are put into operation. This is in addition to the static amps developed by hydrocyliidra, and shock pulses of the vibratory hammer are acting on it.

Under the action of elastic forces adhering the root system to the ground, the springs 10 are squeezed, and the arch rises against the stop into the load frame. under the action of a potential ehppp compressed springs of the disturbing force of the inbrotor directed upwards, the vibrator rushes upwards and strikes briskly, the role l: the nut 14 performs the expensive, the anvil 6 is conveyed through the jaws

the grip directly to the stump, as a result of which the latter, together with the grip and the cargo frame 5, also moves upward, compressing 13. Then, under the action of elastic cleats Mon with the ground, the energy of the compressed spring 13 and the disturbing force of the vibrator 15 directed already downwards, the cargo frame with the grip and by sticking, compressing the spring 0, moves downward against the upwardly moving frame of force before contact with the arch.

Subject invention

1. Device for clearing stumps, including a power frame with hydraulic cylinders.

a cargo frame with a maxillary gripper and a vibrator with an anvil, with the aim that, in order to improve the efficiency of the clearing, the load frame is made with a plate,:; an accentor with B0, the reciprocating movement in a vertical plane, and the vibrator is firmly mounted; .

2. The device, but p. I, characterized in that the plate is made with a guide rod, at the end of which the head is mounted, and the packer is mounted on the beam, with which the lower bracket of the cargo bar, we are equipped with jaws of the grip.
