Description

This invention relates to the mechanization of logging operations and is intended for trimming branches and tree tops.

The aim of the invention is to reduce the energy intensity of the delimbing-pulling device of a logging machine,

Figure 1 shows a logging machine, general view; figure 2 - the working position of the gripping-lopping head; fig.Z - node I in figure 1; 4 is a top view logging machine; fig.Z - technological scheme of the machine; FIG. 6 is a diagram of operation of the delimbing-pulling device.

The logging machine contains a self-propelled chassis 1, on which a pivot in a horizontal plane mounted around axis 2 is a manipulator 3 with an articulated boom and a gripping-cutting device 4 equipped with a tooth 5, and a delimbing pulling device consisting of an actuator 6 of the upper clamp 7 and the lower clamp, executed in the form of a swivel from a hydraulic cylinder 8, point 9 with a roller 10 at the end. A knife 12 is mounted on the axis 11 of the roller, spring-loaded by the plate 13 and bounded by an emphasis 14. The angle of installation of the knife relative to the lever is determined by calculation depending on the cut diameter of the tip.

In front of the dragging. the device is fitted with a gripping-crimping head 15 by means of a horizontal hinge 16 which can be rotated by 90 in the vertical plane from the actuator 17 through the lever 18. At the end of the self-propelled chassis in the plane of dragging, a tray 19 is installed to receive the whips coming out of the pulling device the plane of the chassis is located conic 20 for the accumulation of logs. The delimbing tool with the gripper delimbing head is angled to the longitudinal axis of the chassis so that the pruned knots fall to the side of the chassis, and the tree 21 falls on the cut part of the cutting area.

 Reducing the loader's cycle to allow for idle down of the lopper and combining the operation with the pruning of the branches, and

The machine works as follows. procuring machine.

. The operator moves the manipulator 3 to the tree and cuts it with the help of a shearing device 4. Then

in full-out of the boom it moves the tree to the gripping-delimbing head 15, which is in the initial position (Figures 1 and 2) and transmits it to it. A gripping head 15 clamps the tree, and the operator leads the manipulator 3 to the next tree. After the tree is clamped by the gripping-delimbing head 15, the delimbing-pulling device works without automatic participation of the operator. A head 15 knocks down a tree in a longitudinal axis of the pulling mechanism. The butt end of the tree falls under the upper presser 7, then the lever 9 is rotated and the roller 10 presses the tree against the upper presser 7. After this, the drive 6 of the pulling device is activated and the tree is pulled through the delimbing head.

As the diameter of the pulling tree decreases, the lever 9 changes the angle of inclination, and the angle of inclination of the knife 12 changes. At a certain angle of inclination, the knife 12 engages with the moving tree, sets it in motion and cuts the tip at the desired diameter.

Out of the delimbing-pulling device, a tree cleared of branches and with a truncated tip falls on a tray 19, from which it is fed onto a conic. 20 for packing or falling to the ground (Fig. 5).

The knot and the tips fall to the side of the chassis and the knots can be picked up by pick-ups for further use. If necessary, the knots can be used as a reinforcer of a weak soil, then they are scooped up with the help of teeth 5 by a manipulator under the chassis.

 Reducing the cycle of the gripping and cutting device helps to reduce the delays of the delimbing head and combines the operation of tree felling with pruning of branches, and consequently, increasing the productivity of the forest. The combination of the upper trimming device with the dragging mechanism helps to increase productivity.

machine and reduces drive power consumption.
