Description

FIELD: forestry and woodworking industry.

Machines for processing felled trees are known, including a self-propelled shaosi, on which a tree loading mechanism is mounted, dragging, its device and cutting head with "power cutting tool 1".

In ET1IH machines, protaskivayush, its device and cutting heads with power-cut knives are mounted on the jaw grip of the tree loading mechanism, which reduces the machine's performance due to the need to orient the entire working equipment of the machine to each tree in the bundle when it is captured.

The closest in its technical sushi ness to the offer is a machine for processing fallen trees, including, and a self-propelled chassis, on the frame of which are mounted a rotary maxillary grip for loading trees onto the machine, power cutting knives and longitudinal smashing mechanisms for trees 2.

In these machines, the drawbacks of the above-described machines are partially solved by stirring the knives of force cutting and the mechanism of longitudinal movement of trees on the frame of the self-propelled chassis, separate from the tree loading mechanism, which is a jaw type manipulator.

However, machines of this type, due to the single loading of trees, also have low productivity, and due to the need to take each tree from a pack individually - high energy intensity.

The purpose of the invention is to increase the productivity of the machine and reduce its energy consumption.

This is achieved by the fact that on the frame of the self-propelled chassis between the jaw grip and the mechanism of longitudinal movement of trees, an uncoupler of tree butts is installed, the longitudinal axis of which is parallel to the longitudinal axis of the frame of the trees and the angle close to the straight line. At the same time, the uncoupler of the tree gouge can be made in the form of a wave bearing surface with a longitudinal groove, in which a closed traction organ with pushers is placed.

FIG. 1 shows schematically the proposed maschina, side view; in fig. 2 - the same, top view.

The machine contains a self-propelled engine I with a frame 2, on which are mounted a rotary maxillary gripper 3 for loading trees onto the machine, power cutting knives 4 and mekhapiam 5 for the longitudinal movement of trees.

The KOTOforo axis a-3 makes an angle a with the longitudinal axis bb of the frame 2, which is close to the straight line. On the frame of the self-propelled chassis between the axes b-BI and a-ai, respectively, the jaw grip and the mechanism for the longitudinal movement of trees, an uncoupler of 6 tree glands is installed, with the longitudinal axis r-ri disconnecting parallel to the longitudinal axis b-6i of the frame. The uncoupler of tree butts is made in the form of a wave bearing surface 7 and a traction body 8 with pushers 9 installed in the longitudinal groove of the bearing surface.

Maschina works as follows.

A self-propelled driver 1 is fed to a stack of trees 10, with a maxillary gripper 3 packs of trees are laid on an uncoupler 6 butts of trees, with which they are individually fed into a delimbing device with knives 4 for power cutting and into the mechanism 5 for longitudinal movement of trees. After that, the knives 4 and the working bodies of the mechanism 5 are pressed against the surface of the tree, its longitudinal movement and pruning of branches is carried out.

The maxillary grip provides a load of trees into the machine at its uncoupler, which ensures the continuous supply of trees to the mechanism of longitudinal movement through power cutting knives, and thereby increases the productivity of the machine.
