Description

Woods mounted on platforms 3 of the cross conveyor 1.

Each rotation mechanism 2 is made in the form of a maxillary grip 4, mounted on a cantilever support 5, which is mounted on a rotating rotating disk 6. The disk b is mounted in guide rollers 7 mounted in a frame 8 mounted on a platform 3. The grip 4 contains elongated jaws 9 and shortened jaws 10 with folding spring-loaded ends. A spring-loaded stop L is installed between jaws 9 and 10. The jaws are driven by an electro-hydraulic power cylinder 12, which is powered by trolley 13 by means of a current collector 14.

The proposed device works as follows.

Trees are individually supplied to tray 15. During movement of the transverse conveyor 1, the opened jaw gripper 4 interacts with the tree in tray 15. The shortened jaw 10 with a folding spring-loaded end passes freely under the tree, and the elongated jaw 9 grips the tree. At the same time, using the limit switch 16, the electrohydraulic cylinder 12 is activated, which by this moment is already connected to the trolley 13 by the current collector 14. Next, using the electrohydraulic power cylinder 12, the jaws 9 and 10 are closed, clamping the butt of the tree between the spring-loaded stop 11 and the jaws 9 and 10. Then, the engine 17 is turned on, and the barbed grip 4, together with the tree butt clamped in its jaw, begins to rotate, simultaneously moving by the conveyor 1. When transversely moving the rotating trees, We clamp the body 18 pruning boughs. After the current collector comes out of contact with the trolls 13, the rotation mechanism 2 and the electro-hydraulic power cylinder 12 are turned off. Due to the fact that the center of gravity of the rotating part of mechanism 2 lies below the axis of rotation, the rotating maxillary gripper 4 is always stopped in such a position when the back rest is underneath. Therefore, after turning off the rotation mechanism 2 and

the electro-hydraulic power cylinder 12 of the jaw 9 and 10 is consumed by the TC, and the butt of the tree cleared of branches is pushed out by the spring-loaded support 11 from the gripper 4 and rolls along an inclined plane 19. Similarly, all the mechanisms of rotation 2 mounted on the transverse conveyor 1 operate.

Such a feeding device for a pruning plant will significantly improve the performance of the delimbing plant, as it allows processing trees of different diameters simultaneously and efficiently, which ensures their continuous processing with transverse feeding of trees.

Claims (2)

1. A feeder for an installation for cutting branches from fallen trees, including a mechanism for transverse movement of trees in the form of a transverse conveyor and mechanisms for rotating tree trunks, excepting for that, in order to increase the device's reliability in operation, each mechanism of rotation of the processed tree trunks is made in the form of a platform mounted on the traction organs of a transverse conveyor with a rotatable drive disc in the vertical plane having a cantilever support on which the jaw grip is mounted. 2. The device is according to claim 1, characterized in that, in order to reduce the dynamic loads transmitted to the feeding device in the process of moving and rotating the trees being processed, each maxillary grip is provided with a spring-loaded abutment fixed by the melodion of its jaws.
