Description

one

The invention about THOCHofcH for logging equipment / namely, for logging machines and can be used in forestry pro- gramme.

Known logging machines, including self-propelled chassis, on the frame of which are mounted a pulling device having a lower clamping mechanism and turning in a vertical plane of the vertical clamping mechanism, a receiving device and a cutting head FOR pruning l, 2

Such machines have limited technological capabilities and complex construction. The presence of a guide bearing with: a drive and a BEAM, at the end of which a knife head is installed, greatly complicates the design of the machine and reduces its maneuverability in the cutting area.

The aim of the invention is to expand the technological capabilities of the machine and simplify the design.

This is achieved by the fact that the machine

Equipped with a d / cross device.

ezani wood, with a knife head for pruning and device

For the transverse cutting of wood, set on the upper presser fur, a measure of the pulling device.

In addition, in order to provide copying of the curved sections of the shaft to be machined to the passage of a part of the barrel without cutting the knife head, the branches are connected to the frame of the upper clamping mechanism by means of a beam, which is equipped with power cylinders; its turning

Fig, 1 shows the described machine in the transport position, side view; in fig. 2 - the same, in the working position; in FIG. 3, a machine, a drive from above.

The logging machine contains mounted on a self-propelled chassis 1, the lower pressing mechanism 2, the device, the upper clamping mechanism 3 of the pulling tool, mounted on the hinge frame 4, and the receiving device 5. In the front part of the upper clamping mechanism 3 of the pulling device, there is a cutting head 6 which is mounted on the beam 7, connected to the frame 8 by the hinge 9 and connected with it by the power cylinders 10. In the rear part of the frame 8 a device 11 is mounted for transverse

; at the bottom of the hinge frame 4 there is a mechanism for turning it 12, connected to the sa-1 frame of the undercarriage chassis 1 by hinges 13. The turning mechanism 12 is pivotally connected to the rods of the power cylinders; A moat 14 and brackets 15 of the hinge frame 4. Between the frame of the joint pressure ball 1 and the frame 8 of the upper hold-down mecelium 3 of the pulling device parallel to the hinge frame 4, the power cylinder 16 is pivotally mounted.

The machine works as follows. Force 1 and cylinders 14 with the help of a turning mechanism 12, frame 4 with equipment attached to it is turned forward along the machine. At the same time, the upper pressing mechanism 3 of the pulling device and the knife head 6 mounted on its frame 8 and the cross-cutting device 11 are pivoted to a vertical position.

The machine is moved to the standing shaft and clamped with the grips of the knife head 6 and the device. Then the drive of the cutting organ of the device 11 is turned on and with the help of the power cylinder 16, the directed drunk of the tree is made forward from the machine. Using cylinders 14 using the turning mechanism 12, a fallen tree clamped in the grippers is moved to the side of the machine by turning the frame 4 and placed on the lower presser mechanism 2 of the pulling device, the clamp; its upper clamping mechanism 3 of the pulling device. Then the grippers of the device 1 are unclenched and turn on the upper and lower mechanisms 2 and 3 of the pulling device, pulling the tree through the head 6, with which the branch can be cut. The clamping of the knife head 6 to the tree being processed is carried out by cylinders 10. With the same CRAWN cylinders, the knife head 6 raises above the machined barrel, if necessary, the parts of the trunk without treatment (highly curved pupils, growths, etc.).

The cutting of the treated wood into assortments is carried out by the device 11 for transverse cutting. The resulting assortments are accumulated in the receiving device, and then they are unloaded. In the case of the operation of the machine for cutting trees into assortments in the receiving device, whole whips are accumulated.

The machine described is simple in design and performs all the operations of the technological process from felling to cutting of harvested trees into assortments.
