Description

This invention relates to machines used in logging with pruning and cutting into assortments.

Known logging machine, including a self-propelled chassis, equipped with a body and articulated boom, on the bracket of which there is a yaw mechanism, grippers and delimbing organ. However, the disadvantages of such a machine are the large weight, complexity of the structure and the impossibility of processing the tree in a horizontal position.

The aim of the invention is to increase efficiency.

This is achieved by the fact that the articulated boom of the machine is made with a traverse pivoting in the vertical plane, on which the pivot levers are mounted, having a gripping-cutting device with a delimbing organ at the free ends.

FIG. 1 shows the described machine in the process of logging, side view; in fig. 2 - the same, rear view in the process of cutting a tree from the root; in fig. 3 - the same, top view in the process of laying trees in a stack.

Mr. 3 and a crosshead attached to it, including grippers 4, a sawing mechanism 5, hydraulic cylinders 6 and 7, pivotally mounted levers 8, delimbing working members 9 and 10

and mounted on the chassis "Oz 11.

Before work, the self-propelled chassis / is stopped and, with the help of the hinge of the o-jointed boom 2 with the bracket 3, the device is pointed at the tree, which is clamped by the claws 4 and cut down with the saw mechanism 5. After the cutting, the tree is horizontalized with the hydraulic cylinder 6. When the hydraulic cylinders 7 divorce the levers 8, while the delimbing working bodies 9 through the help of the grippers 4 clamp the tree and pull it through the delimbing working bodies 10. The latter are mixed against the moving tree. When levers 8 reach their extreme

positions, they are assembled by hydraulic cylinders 7. In this case, the delimbing working bodies 10 with the grippers 4 clamp and pull the tree through the delimbing working bodies 9, which simultaneously with the mixing of the tree are mixed towards the tree.

After clearing the branches at the required length, the wood is sawn off with a sawing mechanism 5, and it falls into the body 11. As an exception, with a shallow forest, the machine

location. In this case, the tree is cut and raised, then the grippers 4 are released, as a result, it is lowered under the weight of its weight and, the passage through the delimbing working bodies is cleared from the branches.

In a horizontal position, the machine is able to remove a branch on the entire length of the tree, without cutting it into assortments.

Since the removal of the branches occurs with the simultaneous oncoming movement of the tree and the delimbing working bodies, the time for pruning the branches is halved, which makes it possible to increase the productivity of the machine.

Subject invention

Forestry machine, including a self-propelled chassis, equipped with a body and

an articulated boom, on the arm of which a sawing mechanism is installed, grips and a delimbing organ, characterized in that, in order to increase work efficiency, the articulated boom of the machine is made with a traverse, which is rotatable in a vertical plane, on which the pivot arms are pivotally mounted, having a cutting-cutting device with a delimbing organ at free ends.
