Description

(54) FORESTRY MACHINE

one

The invention relates to forestry equipment, namely, forest logging machines for cutting trees and packaging them.

A logging machine is known that contains a self-propelled chassis, on the frame of which a gripper, its device and horseman 1 are installed.

A disadvantage of the known device lies in its low efficiency.

The aim of the invention is to increase efficiency.

The goal is achieved by the fact that the logging machine is equipped with a frame located perpendicular to the longitudinal axis of the self-propelled chassis, and an additional gripping device, with the main and additional gripping and cutting devices installed at the ends of this frame, and the horseman has a movable frame, ig.yyush , sliders and hydraulic cylinders for reciprocating movement along the chassis frame along its longitudinal axis, the housings of which are attached to the movable frame, and the rods by means of brackets to the chassis frame, while An external frame is attached with a guide and stirring, with a beam with three pairs of grippers, of which one pair of levers is fixed in the middle part of the movable beam, and two other pairs of levers along its edges by means of additional hydraulic cylinders.

FIG. 1 shows a logging machine; in fig. 2 - conic.

Forestry machine contains

10 self-propelled chassis 1 with operator's cab 2, laying, its frame 3, located perpendicular to the longitudinal axis of the self-supporting chassis 1. At the ends of the frame 3 are located the manipulators 4 with gripping-cutting devices 5. There is a rider on the self-propelled chassis 1. 6 with gripping levers 7 and a lifting beam 8.

Konik 6 contains a movable frame 9 mounted on the frame 10 of a self-propelled chassis 1, having sliders 11 and hydraulic cylinders 12 for reciprocating movement along the chassis frame along its longitudinal axis, with the housings of the hydraulic cylinders 12 attached to the movable frame 9, and the rods by means of brackets 13 - to the chassis frame 10. Guides 14 are attached to the movable frame 9 and beam 16, which is displaced into them by means of additional hydraulic cylinders 15, carrying the gripping levers 7.

Logging machine works as follows.

Maschina approaches the wall of the forest so that conic 6 is parallel to it. The hydraulic manipulators 4 are in the initial position, the gripping arms 7 of the conic are slightly opened. Lifting beam 8 of the middle pair of bunk levers is lowered. Each hydraulic manipulator is controlled by a separate operator or it is possible to install a program-controlling device, during work with which the operator takes turns picking-cutting devices with hydraulic manipulators on the trees and cutting them off. In this case, the movement of the trees to the packet forming device, their laying in the grippers and the return of the hydraulic manipulator to the initial position are performed in automatic mode.

Operated by the operator 1, the drovers are guided on the trunks of trees, gripping and cutting devices, trunks are compressed and cut, then the trees are transferred and placed in the shape forming device in such a way that the center of the package severity lies in the plane passing through the middle grips of the package. Adapter device. The laying of small-sized trees is carried out in a zone and with a small number of branches, which ensures greater strength of the package. At the end of deforestation along the entire front of the mashina, the manipulators are installed in the transport position, the package of trees is crimped with gripping levers and connected with reversible drawbaths. The rear grip arms then lower, the lift beam rises, and the bag is dropped to the ground.

In the event that the vehicle delivering the package along the vehicle to the place of loading on the forest transport has a greater carrying capacity than the package collected from one side of the logging machine weighs, the package does not fit, and the machine again moves to the forest wall and the cycles are repeated until a package of trees of the desired weight has been gathered.

Forestry machinery can work as a loader transporter.

For this, the hydraulic manipulators, after the formation of the package has been completed, set up in the transport position and in reverse, adjusting the position of the center of gravity of the package while overcoming the transverse and

the longitudinal slopes due to the movement of the conic's movable beam and the movable frame, the maschina takes the package to the place of loading or loads it onto the forest transport. The logging machine can also carry out such preparatory work,

as cutting flush stumps along the course, laying under the right, disassembling wind plots, etc.
