Abstract

1. CAPTIVE CUTTING DEVICE OF FOREST PREPARATORY MIPMNA, containing a working head, on the body of which the sawing device is mounted, a grip, a supporting prism and an abutment located above the supporting prism, characterized by the fact that, cycle, it is equipped with a fixedly fixed to the stop locking element arcuate shape.

Description

2. The device according to claim 1, characterized in that the width of the fixing element is 0.4-0.9 distances between the axes of rotation of the gripping gripping levers, and

The arcuate ends of the locking element protrude in front of the most concave part of the support prism for a distance of 0.1-0.3 in length of the clamping levers.

I

The invention relates to gripping devices for forest machines and can be used in the forest industry.

Known gripping and cutting devices of logging machines, containing a working head, on the body of which are mounted a sawing device, a grip, a supporting prism and an emphasis above the supporting prism.

D3 and 23.

A disadvantage of the known constructions is that their stops work only during the completion of the operation of the rolls, which somewhat reduces their functionality.

The purpose of the invention is to improve the performance and increase the efficiency of use of the device by reducing the cycle time.

The goal is achieved by the fact that the device containing the working head is on the corpus; the saw apparatus, the catch, the supporting prism and the stop located above the supporting prism, are mounted with a fixed-shaped arcuate element mounted on the support.

The width of the fixing element is .0.4-0.9 the distance between the axes of rotation of the clamping grips, and the arcuate ends of the fixing element are protruding in front of the most concave part of the support prism at a distance of 0.1-0.3 of the length of the clamping levers.

FIG. 1 shows a gripping-cutting device of a forest machine, side view; in fig. 2 the same, top view.

.2

The gripping and cutting device of the logging machine contains a working head, on the body 1 of which the sawing device 2 is mounted, and the wath 3, the supporting prism 4 and the stop 5 located above the supporting prism. The stop 5 is provided with a fixedly fixed fixing element 6 of arcuate shape, the width of which is 0 em 0.4-0.9 distance between the axes 7 of the turn of the clamping gripping levers, and the arcuate ends of the fixing element protrude in front of the most concave part of the supporting prism on

5 distance 0.1-0.3 clamping arm lengths.

Capture-cutting device with fixing element arcuate shape works as follows.

The operator directs the boom of a logging machine with a gripping-cutting device at the tree being cut, with the grippers being opened. At the time when the tree is inside the gripping-cutting device, the prism touches and with any side of the locking element. The operator then presses the Capture-cutting device to the tree and it is self-centered in it, i.e., the support prism and the arcing-shaped fixing element. the time it takes for the cut-off device to cut into the tree is reduced. Moreover, the tree always after its clamping with the clamps is along the axis of symmetry of the gripping-cutting device, which excludes large chipping of trees when felling.
