(54) TRIMMING MACHINE

FIELD: forest industry.

A known machine for pruning branches with vertically and horizontally arranged tree trunks. Such a machine includes a self-propelled chassis with a hydraulic manipulator, a sliding rack with a delimbing organ and a clamping device. The sliding gear with all the mechanisms is fixed in the tire to the arrow of the hydraulic manipulator. When; - jy this boom is experiencing dynamic and -,: static loads, which reduces the reliability and performance of the machine.

The purpose of the invention is to increase the exploitation of the j5 quality of the machine for pruning, h

This is achieved by the fact that the sliding stand with the delimbing organ and the clamping device are mounted on a self-propelled chassis using a rotatable B vertical plane of the platform, which is equipped with a movable outrigger, with the sliding stand mounted on a turntable and articulated with balance rods D5

and the upper link of the extendable rack is made with a longitudinal traverse to move the delimbing organ.

FIG. 1 is a schematic illustration of a delimbing machine; the operating position in FIG. 2 - the same transport position.

The branch cutting machine 1 includes a self-propelled chassis, a hydraulic manipulator 2 mounted on a rotary column 3, having an arm 4, a winch 5, a platform 6,: rotatable in a vertical plane about an axis 7 by means of a hydraulic cylinder 8 and equipped with a movable outrigger 9. On a turntable 6 a hinged-sliding stand 10, having a balance spring 11 and a delimbing head 12, is installed. Such a structure of the stand 10 allows the delimbing head 12 to be adapted to the curvature of the webs from the tree. The upper link 13 of the sliding stand 10 is made with a cross-bar 14 for moving the delimbing head 12. On the turntable 6, the clamping device 15 is rigidly mounted. In the transport position, the turntable 6 I

Iodnatv, and sliding the Yu is folded I and leans iia shoulder 4 of the rotary column I 3..

Pruning branches from a tree is carried out as follows: b;

Hydro Ndrom 8; the platform 6 rotatable in a vertical plane to the plane 6 is rotated into a working position convenient for turning j, cutting arms) vertical, inclined

1 or horizontal .. 10

The hydraulic manipulator 2 inserts the tree - I with a cleat through the delimbing head 12 into the clamping device 15, after which the delimine head 12 and the ladder 5 turn on the delimine. Through the cable assembly system 16 J5, the stand 10 is moved apart with the form for keeping the tree in working position-1 SRI (sled) sak sliding rack 10, and its own tree trunk. The upper link 13, moving forward, moves the knot-20 carved head 12, which cuts off the bough from the tree. After the branches are trimmed, the extension stand 1O with the delimbing / head 12 is lowered by the cable system to its original position. Clamping device 15 y & frees the whip, and the hydraulic manipulator 2. {puts the whip to the loading area; ;

ku or on the vehicle. Further, the duty cycle is repeated.
