Description

The invention relates to forestry equipment and can be used in forest industry and forest management.

Known logging machine, including a self-propelled chassis, equipped with a body and an articulated beam boom g on a bracket which is equipped with a sawing mechanism, / grips and 1 e-shaped body 1.

The disadvantages of this machine are the large size and; tivna complexity. During the transfer of a fallen tree into the body, it is possible that the rollover may occur due to a massive bracket. The period of movement operations takes a long period of time, which affects the productivity of the movement.

Also known is a logging machine for felling and hauling trees, including a self-propelled chassis on which the rider is mounted and the feller-loading equipment consisting of hydraulically driven ones. articulated boom and mast with gripper cutting device G2 .. - The disadvantage of this machine is the presence of large dimensions and mass of technological equipment.

A pick of the wormwood on carrying and laying down the cut tree takes a long period of time, which in a short run affects the performance of the machine.

The purpose of the invention is to increase the productivity.

The goal is achieved by the fact that in the logging machine, the mast is equipped with screw guides and a slider installed in them, and the gripper device is mounted on the slider .;

FIG. 1 shows a forest 15 on the machine when felling a tree, side view; in fig. 2 - the same, when loading wood into a conic; in fig. 3 - position of the gripping-cutting mechanism with a slide at the initial moment of them

20 sliding down the mast — in FIG. 4 - the same, at the final moment of sliding along the mast and at the moment of cutting the tree into a conic,

Forest logging machine for

25 tree skiddings consists of a self-propelled chassis 1, on the frame 2 of which a conic 3 is mounted and a wood loading equipment, including articulated boom

Claims (1)

30 4 and the mast 5, bounded on both sides by the stops 6 and 7, and also having a slider 8 on itself, with which the gripping device 9. The mast 5 is equipped with screw guides 10, in which the slider 8 is installed. The machine works as follows. The car drives up to the standing tree and with the help of a hydraulic system, we have a gripping device 9 on it. After the tree has been cut, the CTpejiai 4 and the mast 5 of the machine are lifted and hydraulically lifted to the loading position,. In this case, the slider 8 during the movement down along the guides 10 below. Acting its own weight of the body when the mast 5 is turned on by the action of hydraulics. a certain angle in the vertical plane, at the same time makes a turn at the required angle in the direction of the conic. After moving all the equipment to the loading position, the cut tree is dumped into a conic. When performing the described operation in reverse order, all the equipment of the machine returns to its original position and it is ready to repeat the cycle. The advantage of the proposed mother grab for valigues and skidding trees is that it is due to the presence of a mast with screw guides and a slide that moves along it under its own weight of weight and simultaneously rotates at an angle . Invention Formula / .... . A felling machine for felling and skidding trees, including a self-propelled chassis, on the frame of which a broomstick and feller-loading equipment are mounted, consisting of hydraulically controlled articulated boom and mast with a gripping-cutting device, distinguish 7 in order to increase productivity, the mast is equipped with screw guides and a slider installed in them, and the gripping-cutting device is mounted on a slider.
