This invention relates to logging machines for cutting trees, pruning and baling.

The known logging machine includes a self-propelled chassis, on which a cabin and technological equipment are installed, containing a manipulator with a gripping-cutting device and a beam pivoting in a vertical plane, placed on a turntable, equipped with a pruning mechanism, pulling device, telescopic boom, on a free end which is set to grip, drive clamping roller, located between the grip boom and pulling mechanism 1.

However, the installation of a vertical turning beam on a rotating circle in a horizontal plane is accompanied by an increase in the vertical coordinate of the center of mass of the machine, which reduces its lateral stability. In addition, at a high position, the turntable closes the machinist from her side to form a blind area. This reduces the number of trees processed from one side of the machine, especially on slopes, and consequently, the technological capabilities of the machine. During the operation of this machine, it is not possible to provide such a technological method as leveling the ends of the tops of the whips in the bundle, because after leaving the pulling device, trees of different weights pass through inertia different distances. Moreover, a technique such as the formation of bundles of volume equal to the trip load of the skidder, since a bundle of whips is formed by the machine on the ground and includes only those trees that are within the reach of the manipulator, with the exception of trees in non-request mating areas from the cab. It also reduces the technological capabilities of the specified machine.

A logging machine is also known, which includes a self-propelled chassis with hinged articulated semi-frames, on which an operator's cabin and technological equipment is installed, which contains a manipulator mounted on the front half-frame with a shearing-cutting device and a bend that is rotatable in a vertical plane and fitted with one side mounted a dragging device and a mechanism for cutting branches, a mechanism for trimming vertices, an additional dragging device in the form of upper arms and lower rollers and conics. During the operation of a known maschina, it is possible to reduce the spread of the ends of the whips of the whips in the pack by sawing off the inclinations with a crosscut saw 2.

However, the installation of a vertically rotatable beam on the rear carriage is also accompanied by a significant vertical coordinate of the center of mass of the known machine, which reduces its stability, visibility to the machinist, the working area, and consequently, the technological capabilities of the machine. The location of the vertical axis of rotation of the manipulator behind the transverse axis of the front balance truck reduces the useful reach of the manipulator, the number of trees cut from one side. When using a famous car

for the harvesting of logs, the formation of a stack of logs from several machine stands is difficult, since its storage bins do not have clamping devices. Dumping the logs onto the ground, mine bunkers, also allows you to get a pack of

whips from only one station, the well-known maschina also has reduced visibility from the side of the beam, and, consequently, its working area and technological capabilities. The purpose of the invention is to increase the technological capabilities of the maschina.

The goal is achieved by the fact that the axis of rotation of the beam is located on the front half of the frame, and the additional dragging device and the branching mechanism are located at the other end of the beam.

The upper drum of the additional dragging device is movable in a vertical plane passing through the axis of the lower roller.

In addition, the conic is movable in the horizontal plane, perpendicular to p

Noah longitudinal axis of the rear semi-frames.

FIG. 1 shows a logging machine, side view; in fig. 2 - the same, view from the side of a conic; in fig. 3 - the same, when the machine is laying wood on the waiting mechanism; in fig. 4 - the same, when cutting the branches and feeding with the manipulator of the next tree.

The logging machine includes a self-propelled chassis 1 with a front balancing 2 and rear 3 articulated semi-frames, a cab 4 operators and technological equipment.

From the technological equipment on the front frame 2 there is installed a manipulator 5 with a gripping-cutting device 6 and a beam 7 rotating in a vertical plane, equipped with an expectation mechanism 8 and a branch trimming mechanism 9, a main 10 and an additional 11 pulling device, a trimming mechanism 12. The vertical axis of rotation of the manipulator 5 is located in the area of the front frame 2, and the axis of rotation of the beam 7 is placed on the front frame 2 in front of its axis of swing. An additional dragging device 11 is placed in the area of the rear half-frame 3, with the upper roller of the device 11 mounted on the lever 13 of the linearly guiding Chebyschev mechanism. The rear frame 3 is provided with a conic 14, which is made movable in a transverse plane relative to the rear frame 3, for example, by means of a slide 15. The machine works as follows. The self-propelled driver 1 is moved along the edge of the cut along the tape with a width equal to twice the maximum reach of the manipulator. After installing the maschine, the manipulator 5 is directed onto the tree 16, captured and cut by its gripping and cutting device 6, the cut tree 16 is removed and its butt part is placed into the opened branch pruning mechanism 9 and the main pulling device 10 (if the beam 7 is free) or on the waiting mechanism 8 (if the beam is occupied). In the latter case, the laying of the cut tree 16 into the branching mechanism 9 and the main pulling device 10 is performed by the waiting mechanism 8 automatically at the moment of release of the beam 7. After laying the butt of the tree 16 onto the beam 7, the branching mechanism 9 and the main pulling device 10, the tree is fed along beam 7 while cutting the branches. When moving along the beam 7, the butt part of the tree rests against the upper roll of the additional pulling device 11, lifts it, automatically turning into operation. The tree is then pulled through by both pulling devices 10 and 11, which increases the pulling force, and after leaving the main pulling device 10, the whip is picked up along the beam 7 by an additional pulling device 11 into the broom, goes out of the device 11, stops, after which the mechanism 12 cuts off the whip and the whip are dropped into the conic 14. The application of the invention will improve the technological capabilities of the proposed maschina.
