The invention relates to a device for felling trees harvesting machines and can be used in the forest industry.

Known gripping-cutting device, including the power levers, one end of which is connected to the power cylinders and the other with the cutting knives, levers, grips the front part of which covers the trunk, and the back ends are connected with the hydraulic cylinder of the trunk of the tree (Cm. avts N 1308264, CL A01G 23/08, 23/06).

A disadvantage of the known device is that it does not ensure continuity of the process of felling trees. In addition, the use of force knives leads to the splitting of the butt of the tree and to the need to increase the pressure in the hydraulic system.

It is also known gripping-cutting device comprising gripping levers and hydraulic drive containing the pump associated with the cylinder gripping levers and blade mechanism with hydraulic drive (See. avts N 1083966, CL A01G 23/08, F15 11/20).

The main disadvantage of this device is that it does not have high performance, as it does not ensures continuity of the process.

Known gripping-cutting device harvesting machine, comprising a housing with clamps and frame with mounted on it saw mechanism with a hydraulic actuator, a frame mounted in the guide housing with the option of reciprocation (See. avts N 1126247, CL 01G 23/08. The prototype).

A disadvantage of the known device is that after you touch the tree gripping arms is stop boom manipulator, cutting wood carried out only after his capture, and the directions of the tree with jumper only after cutting. That is, there is a discrete process rolls.

The above deficiencies lead to reduced productivity on the harvesting of trees.

The present invention is gripping-cutting device for harvesting trees includes a housing, a hinge mounted on the boom arm, the carriage transfer mechanism, which is mounted in the guide housing with the possibility of reciprocating movement, the saw mechanism with actuator and gripper levers, according to the decision of the gripping levers pivotally mounted on the carriage and pivotally connected with the mechanism of its movement, which other end pivotally connected with the casing gripping-cutting device. In addition, the mechanism for moving the carriage in the form of hydraulic cylinders, which are connected with the body with the formation of the internal cavity, and a gripping-cutting device is further provided with a delimbing device.

Comparative analysis of the prototype revealed the following distinctive features:

- gripping levers pivotally mounted on the carriage,

- gripping levers pivotally connected with the mechanism for moving the carriage,

the mechanism for moving the carriage and the other end pivotally connected with the casing gripping-cutting device.

An additional distinguishing feature is that:

the mechanism for moving the carriage in the form of hydraulic cylinders associated with the case with the formation of internal cavities

capture-cutting device is further provided with a delimbing device.

As can be seen from the comparative analysis identified a set of essential features is new, therefore, a legitimate conclusion that the influence of this combination of features to achieve the claimed invention, the result is unknown, and therefore, the alleged invention conforms to the criterion "novelty".

Analysis of patent and scientific and technical information in the forestry and logging industry, held by funds Charcnt and division chief designer of OJSC "HTA" showed that the proposed solution goes beyond the current level of technology in this field. Therefore, it is possible to recognize the relevant criterion of "inventive step".

The objective of the proposed technical solution is to increase the manufacturer of the spine of labor in logging operations.

The solution of the problem is due to the articulated connection of a gripping levers simultaneously with the carriage and the mechanism of its movement, performing the hinge connection between the body gripping-cutting device and the other end of the mechanism for moving the carriage.

The stated set of essential features gives the claimed technical solution is a new property that allows us to solve the problem.

The proposed device can be manufactured in an industrial environment plants large plants or specialized small businesses using standard equipment.

Therefore, the claimed device meets the criterion of "industrial applicability".

We offer pick-cutting device for harvesting trees is illustrated by drawings, where:

Figure 1 - gripping-cutting device

Figure 2 - General view (top view),

Figure 3 - cross section B-B in figure 1 (clamp shaft deivasigamani levers with continued movement of the boom arm and started moving body gripping-cutting device),

Figure 4 - cross section B-B in figure 1 (end position gripping-cutting device before pushing the tree).

A device for the implementation of the proposed device includes a housing 1 with the guides (the drawing is not marked), the hinge is mounted on the boom 2. Reference prism 3 pivotally mounted on the housing 1 and is adjustably connected by means of the hydraulic cylinder 4 arrow 2. In the guide (drawing not labeled) of the housing 1 a of the carriage 5 with the possibility of reciprocating movement relative to it. The mechanism for moving the carriage 5 in the form of hydraulic cylinders 6. Gripping the lever 7 pivotally mounted on axes 8 and 9 of the carriage 5 and pivotally connected with the rods of the hydraulic cylinders 6. Last the other end (corps) pivotally connected with the housing 1 capture-cutting device. Drive 10 saw mills 11 is installed on the housing 1 capture-cutting device.

The device operates as follows.

The operator by means of arrows 2 suggests gripping-cutting device in a horizontal position on the tree. The carriage 5 is in the source (left side) position. In this gripping levers 7 apart, and the reference prism 3 is a right end position (smfg).

At the contact of the short arm (drawing not labeled) of the gripping lever 7 with the surface of the trunk of the tree stems (the drawing is not marked) begin to "get involved" inside (the drawing is not marked) of the cylinders 6. (6 cylinders carried out in automatic mode.) In this gripping levers 7 are rotated around the axes 8 and 9 and begin to clamp with the ox tree (see 3). At the same time (since the clamping of the tree trunk) case 1 arrow 2 continues relentlessly to move relative to the carriage 5 to the moment of cutting wood saw mills 11. In this case, the rod (the drawing is not marked) completely retracted into the housings of the hydraulic cylinders 6 (see figure 4).

Before completion of the process of sawing wood (with continued movement of the housing 1) support the prism 3 is automatically supplied by the hydraulic cylinder 4 to the barrel cut down the tree, and after cutting the continued movement of the boom 2 is pushing a tree with jumper. While supporting the prism 3 and the shaft 2 is set to the direction of felling a tree (upon further movement of the reference prism 3 relative to the housing 1).

When the operation completes directional felling wood carriage 5 and the gripping levers 7 are returned to the initial position, the rods (the drawing is not marked) fully "extended" from the housing (drawing not labeled) of the cylinders 6. Reference prism 3 is returned to its original position.

Gripping-cutting device is ready to perform the next cycle felling trees or cutting of branches with the same gripping-cutting device through delimbing device of any known construction mounted on the gripping-cutting device.

Declare : ethno-cutting device for harvesting trees has the following advantages: the process of directional felling of the tree starting from the touch of his gripping-cutting device before laying on the ground carry out continuous movement of the boom arm in an automatic mode that allows you to increase productivity.

An additional advantage of gripping-cutting device is the presence of internal cavities, perform the function of "pocket-drive for installation of small-diameter trees, which also contributes to increased productivity.
