(54) TRAVELING MACHINE

I

BACKGROUND OF THE INVENTION The invention relates to machines for dragging and dropping trees and can be used in the forest industry.

The known skidder contains a self-propelled chassis, on the frame of which a bracket is rigidly fixed, on which the plate is installed, which can be rotated around a horizontal axis by means of a hydraulic cylinder connected to it with its own stem, and rotated around a horizontal axis.

11el of the invention - the performance of the machine.

To do this, it is provided with a support rigidly fixed on the plate, which interacts with the frame in the transport position, and the hydraulic cylinder body is hingedly mounted on the bracket.

FIG. 1 depicts a skidder,. side view in transport position with a package of trees to be treasured;

in fig. 2 - the same, in the working position when picking up packs of trees lying on the surface of the earth ;; 3 - the same, in the working order when collecting a pack of trees, lying: below the surface of the earth.

The skidder includes a self-propelled chassis 1, on the frame 2 of which the bracket 3 is fixed. To this bracket an articulated frame 5 is attached to it by means of an axis 4, having the possibility

To rotate in the vertical 1 layer of the plane relative to the horizontal axis 4 by means of the hydraulic cylinder 6, the cortus of the hydraulic cylinder 6 is pivotally attached to the bracket 3, and the rod to the frame 5. On the frame 5

IS is an articulated boom consisting of a front 7, rear 8 supports, KOTOfSJe in the upper part is pivotally connected to the arm 9, which carries on itself the gripping body 1O dl. capture fallen de20 rove 11.

Claims (1)

A hydraulic cylinder 12 is pivotally attached to the rear support 8, the casing of which is pivotally attached to the frame 5. 39 The machine operates as follows. When collecting a pack, only} ((on the surface of the earth, the machine pulls back to the front part of the stove of trees 11. To collect the pack, the gripping body 10 is cleared, and the handle 9 is lowered on supports 7 and 8 under the action of a hydrosystem 12 and The jaws of the Gripping organ 10 are closed under the bundle and are gripped. Then the handle 9 with supports 7 and 8 returns to its original position by means of a hydraulic cylinder 12f lifting the gripper and the front part of the pack of trees above the ground, reducing the size At the same time, the height and aa of the rear axle of the point of application of the technological load — bundles of trees. In this position, the bundle of trees travels to the place of unloading. The machine is unloaded by opening the jaws of the gripping organ When collecting bundles of trees lying below the ground surface, the machine backs up to the recess on the surface of the earth in which the bundle of trees is located. For the collection of the bundle, the gripping body 10 is knocked out, and the handle 9 is lowered on supports 7 and 8 under the action of the hydraulic cylinder 12. As the hydro-cylinder 12 does not provide The lowering of the handle with the gripping body below the ground surface, on which the skidder is standing, is turned on, the hydraulic crank 6 is turned on. The hydraulic cylinder 6 rotates the frame 5 about the axis 4 together with the supports 7, 8 and the handle 9 with the gripping body 1О. In this case, the handle 9 with the gripping body H is lowered below the surface of the earth, and the gripping body is brought close to the pack of trees. Then the jaws of the gripping organ are closed under the pack and captured. Further, by reverse stroke of frame 6, frame 5 returns to the initial one. / position. Then, the guard 12 is turned on and the handle 9 with the supports 7 and 8 is returned to the transport position, raising the catch and the front part of the shaft of trees above the ground. The unloading of the machine is carried out by opening the jaws of the gripping organ Y. The proposed design of the skidder has, compared with the known constructive solutions, such an advantage as the lower intensity of the hydraulic cylinders of the drive. This machine has advanced technical capabilities that improve its performance by increasing the range of the mobile body with a gripping body and ensuring the capture of fallen trees that are below ground level when working on rough terrain and in horizontal mounts. The combination of these useful properties makes the skidder more efficient. The economic effect of such a machine increases by up to 15% compared with those currently in operation. Claiming machine containing a self-propelled chassis, on the frame of which a bracket is rigidly fixed, on which the plate is installed with the possibility of rotation around the horizontal axis by means of a hydraulic rod connected to it with its stem the plate is provided with a boom with a gripping organ1 "4, which is rotatable around the hormontal axis, characterized in that, with the aim of raising its operational qualities, it is rigidly equipped akreplennoy plvte on a support interacting with the frame in the transport position and the body gidroshlvndra pivotally mounted on the bracket.
