Description

I

The invention relates to a device for cutting branches from felled trees and can be used in forest areas.

Devices for cutting limbs from felled trees are known, including a beam rotating in a vertical plane with a delimbing organ fastened at its front end and a dragging mechanism with a grip mounted on the beam.

However, devices of this design do not provide an increase in productivity.

The purpose of the invention is to eliminate this deficiency.

To do this, the device is made with the grip m mounted on the rear end of the beam.

FIG. 1 shows a device for cutting branches from fallen trees, front view; in fig. 2 - 1 view along arrow A in FIG. one.

The device includes a beam /, mounted on a self-propelled means 2. The beam can be rotated in a vertical plane relative to axis 3 by means of a hydraulic cylinder 4. At the second end of the beam, there is a mischief of head 5. There is a device at the rear end of the beam a trunk consisting of a bracket 6 of a curved lever 7 mounted on an axis 8 and a hydraulic cylinder 9 leading it B On the bracket

a fixed knife W is installed. At the bottom of the beam / moves, wats, IL, IL. The gripper can be driven by any known method. The device works as follows.

With the help of the hydraulic cylinder 4, the beam / tilts with its front end to the trees' lacquer and takes the tree by the apical part for some races, one hundred PM1 From her bone. Then the grip // presses the tree and the protaok | Vaet it through the head 5, cf, knock it. With the approach of the grip to the rear body of the beam, the operator, using hydrocylindra 9, turns the curved lever 7 that: In such a way that it supports the size of the tree from falling down. The gripper is then opened and idling towards the front end of the beam, and the next part of the tree is processed.

Prior to this, the operator with the same lever 7 has the ability to cut off the top part of the tree by pushing it onto the knife 10. When processing the tree is completed, the head and the lever 7 of the supporting device are simultaneously opened, and the tree falls to the ground.

Then the wood processing cycle is repeated.

Subject invention

1. A device for cutting branches from felled trees, including turning in

A vertical plane beam with a delimbing organ fixed on its right end is movably mounted on the beam with a gripping mechanism, characterized in that, in order to raise the manufacturer: but the device is made with a gripper installed at the rear end.

2. A device according to claim 1, characterized in that the grip is made in the form of a bracket with a curved lever newly installed in a vertical plane.

3. Device but nn. 1 and 2, characterized in that, in order to make it possible to cut the top of the tree, a knife rigidly fixed in a bracket is installed on the bracket, in a flat, ragged manner, on the parallel plane of turning the lever.
