(54) CAPTURE-CUTTING DEVICE OF A FORESTRY MACHINE

This invention relates to the mechanization of work in the forest industry and forestry.

Known gripping and cutting device of a forest machine, mounted on the boom and includes a working head with a gripping and cutting mechanism, a hydraulic cylinder turning the working head and the stop.

However, such a device does not provide directional felling of trees over 40 cm, and because of the insufficiency of the moment of felling. An increase in the moment of change at the location of the construction will lead to the need to reduce the strength of the manipulator, which will significantly increase the weight of the latter, and the atom will negatively affect the tractor tractive effort and reduce the productivity of the machine.

JJejiJa invention - improving the performance and reliability of the directional knoval.

The goal of the test is to ensure that the device is equipped with an additional emphasis mounted on the hydraulic rod, the turning head of the working head and the interacting

in the process of working with the main emphasis, which is mounted on the body of the working head.

FIG. 1 shows a gripping-cutting device of a logging machine, general view; in fig. 2 is a section along A-A of FIG. one; in fig. 3 - hydraulic circuit of work of the hydraulic cylinder of rotation of the working hopovka.

The gripping-cutting device of a logging machine consists of a working head 1 with a gripper 2 and a shearing mechanism 3, as well as a hydraulic cylinder 4, turning the pAO -:., -; i СЛЛОВКИ 1, on K: :) which pfiyce was upped; vaop 5. A stop 6 is installed on the rod of the hydraulic cylinder in the HEARS of the working head. The cavities of the hydraulic cylinder 4 are turned by the safety head 7,

The operation of the gripping-cutting device of a logging machine is carried out in the following manner.

With the help of a pendant or an “articulated” archery1, the device is aimed at a tree, while the cushion is 1 g:, -: walking in the mountainous position, its mouth is made of wood in the desired npatyieHHH, J / After this, the shearing mech-znizm 3 starts cutting the tree squeezed in the working tongue 1 by the gripper 2. At the same time the working fluid is fed into the strip 1 of the cylinder 4 from the side opposite to the stop 6, The rod of the hydraulic cylinder 4 moves to the right, and the stop 6 enters contact with an anvil 5 that rests on a tree being cut. Thus, an additional moment of directional tree fall is created, which in turn leads to an increase in productivity of the logging machine. In the case of cutting the tree before the hydraulic cylinder 4 makes a full stroke, and the hydraulic cylinder control is turned off, the oil from the hydraulic cylinder cavity from the side of the stop 6 migrates to the other iolost of the hyd- g; g,) 1 nlindra through the safety valve Mill 7, which is adjusted to the pressure necessary to return the head 1 to the horizontal position, - Control g and the hydraulic cylinder m may be 4-L. interlocked

i.

but with one of the working bodies through the valve of coordination, for example with the control of the gripper 2.

The application of the proposed invention will improve the performance and reliability of the directional felling of trees.
