Prism refers to tree-cutting devices that can be used in the forest industry.

Known devices for svv razhdy trees, mounted on a turntable; a mobile chassis and containing an inclined orib ru in which the boom is movably mounted with a gripping-cutting organ ij, 2.

However, devices of this design are designed to provide an expensive

Reni technological capabilities.

The purpose of the invention is to eliminate these disadvantages.

For the free end of the boom, there is a fork with rollers spaced along the height, and curved rails are mounted on the body of the aforesaid cutting organ;

FIG. 1 shows the proposed device at the moment of cutting the tree, general view; in fig. 2 - the same, at the time of the fall of the tree; in fig. 5 is a section A-A of FIG.

, On a self-propelled chassis 1 with a swivel placg Form 2, an inclined support is mounted in the BIH of the frame 3 with a guide .4, in which the boom 5 is movably mounted, the free end of which has a fork 6 with rollers 7. on rollers 7, in contact with them with figured guides 9.

The movement of the boom 5 and the gripping-cut of the Yuschego body 8 is carried out accordingly. ; but from hydraulic cylinders 10 and 11.

During the operation of the machine, the gripping body 8 is adjusted to the trunk tree of the growing tree by rotating the platform 2 and moving the boom 5 along the guide 4 in the frame 3.

The height of the cut is achieved by lowering the gripping-cutting organ 8 by the hydraulic cylinder 11, while along the rollers 7 a straight line of guides is moved

9.

When approaching the car as a result

Shuffle boom 5 along an inclined guide 4 and the cut tree rises automatically. .. If this lift is not enough to transfer the tree, then the hydraulic cylinder 11 lifts the tree together with the gripping body 8 relative to the boom 5, and the straight section of the guides 9 will mix along the tracks 7 to increase the stability of the machine when moving the tree to the place of laying, the tree can be tilted to the side of the machine, raising the gripping; cutting body 8, while the roller 7 is in contact with the upper curvilinear part of the surface of the guide 9. At the place where trees are packed, the gripping cutting body 8 is raised it is from a machine dropping a tree into a bag, while the lower curvilinear part of the guide 9 contacts the rollers 7. Using the invention allows, by reducing the weight of the turntable, to use a simpler undercarriage system and a lower power engine and to simplify the control of the gripper body.
