CS215994B1 - Tree-pulling plant - Google Patents

Abstract

The invention solves the problem of extracting a felled tree from a stand along a pulling line to a delimbing or derived multi-operation machine in the training of a stand by thinning. The subject of the invention consists in installing a non-winding drum of a winch on the drive shaft of a feed roller intended for pulling the trunk through the knife head. With this device, the entire transmission of the feed roller is used to transfer power from the engine to the slowly running shaft of the winding drum of the winch

Description

BACKGROUND OF THE INVENTION The present invention relates to an apparatus in a tree-withdrawn plant which has been installed on a self-propelled ventilating or derived multi-operation mining machine. In the Scythe, the previously known self-propelled forest branching and derived multi-ripper machines for rewrapping, the reel is installed either on the tailgate with its own hydrostatic drive or with a mechanical drive, or it is located by a handling drive with hydrostatic drive. The pull-out winch on these machines needs a transmission to power their own, ensuring power transmission from the engine winding drum and providing engine speed reduction to the winding drum speed.

Given the above-mentioned drawbacks of the need for a genuine transmission to transmit power to the engine of a self-propelled or derived multi-operation mining machine equipped with feed rollers, the reel drum is attached via a connector on the feed roller shaft. The bracket rotatable around the shaft of the shaft carries the reel rope guide.

The feed rollers serving to extend the log through the knife head have both a sufficient speed and a suitable speed for the reel drum. By connecting the shaft and the feeder roller to a tree-pulling device that has the drive part of the drive roller conveyor, this equipped, forest-based, and de-aerated multi-operation mining machine is capable of bringing the eam, in particular, to a manipulated tree into the handling zone. a device after a pull-out or a hard-to-reach place.

The attached drawing shows the mounting of the winch drum on the feeder shaft. On the body of the transmission roller housing 1, a 2-drive hydraulic motor is mounted. A winding drum 2 is mounted on the common shaft 6 via a coupling 6 and not a wound rope J. The bracket 6, which is rotatable about the shaft shaft 4, carries a guide bar 8 which is automatically directed to the desired direction.

By disconnecting the clutch, the rope is unwound freely and at the same time the detached drive of the winding drum is vented. After clamping the tree with the harness, the tree is pulled to the machine by closing the clutch while the feed rollers are running. The winding drum wound by a branching or derived multi-operation mining machine eliminates the need for a dexterous mechanism ensuring the tree is pulled out of the stand to the machines.
