Description

(54) NECK TRAINING MACHINE

one

The invention relates to matinets for pruning branches of pine trees and can be used in the forest industry.

 Known twine machine, including a self-propelled chassis, a manipulator, a mechanism for pruning, pulling and receiving-dropping device 1.

Also known is a twine machine, which includes a self-propelled chassis, on the frame of which a tree loading mechanism, a crawler dragging device with upper and lower tracks and cutting heads 2 are installed.

The disadvantage of these machines is the inconvenience of loading trees into the pulling device.

The purpose of the invention is to increase productivity by improving the load of trees in a pulling device.

This is achieved by the fact that the upper caterpillar of the pulling device is made with lateral longitudinal guides, the cutting heads being mounted in the longitudinal guides by means of igarnir and provided with a drive for turning the vertical plane.

FIG. 1 is a schematic view of the twisting machine, side view; in fig. 2 - dragging device, rear view.

Claims (2)

The scythe machine contains a self-propelled chassis I, on which the lower 2 and upper 3 ryceHHiiii pulling devices with cutting heads 4 and 5 are mounted. along guides 8 by means of hydraulic cylinders 9. The tracks are driven, for example, by hydraulic motors 10 and P. On the frame of the lower track 2, two stops 12 are mounted in shape, for example, spheres, and on the frame of self-propelled utacci there are two supports 13 in shape, nap Emer, n.) lukruga. The same stops 12 and supports 13 are provided with an upper caterpillar 3 and carriage 7. Rest stops 12 and supports 13 are ways to change the angle of inclination of the tracks 2 and 3 in the vertical plane "") A hydraulic manipulator 14 is installed on pichi I to load trees into the protas. a thundering device. The longitudinal guides 15 are made on the sides of the frame of the upper caterpillar 3, in which the frame 16 of the cutting heads 5 is installed, with the possibility of longitudinal movement and turning in a vertical plane by means of the drive 17. The machine is installed on the shoots of trees opposite the cutting heads 4 centners 5. With hydraulic cylinders 9, upper caterpillar 3 is lifted along guide 8; at the same time, the drive 17 cutting heads 5 on the frame 16 move along the guides 15 in the direction of arrow A and rise (see the sketch image in Fig. 2), releasing the front of the operation to the manipulator 14, laying the tree between the tracks 2 and 3 requires pruning boughs In this case, the lower caterpillar 2 takes the same angle of inclination as the planted tree. The maximum angle of inclination is limited by the stops 12 and the supports 13. Then, when lowering, the upper caterpillar 3 presses against the surface of the trunk, the cutting heads 5 are returned by the actuator 17 to the working position. Further, due to the hydraulic motors 10 and 11, the tree is pulled by caterpillars 2 and 3 through the cutting heads 4 and 5. In the process of pulling, the branches are cut. Then the cycle is repeated. 74 By improving the conditions for planting trees in a pulling device, the processing cycle for a single tree is reduced, which according to preliminary calculations increases the productivity of the machine by 8-10%. Claims of invention The Twp machine, including a self-propelled chassis, on the frame of which a tree loading mechanism is installed, a crawler dragging device with upper and lower caterpillars, and cutting heads, in order to increase productivity by improving the loading of trees into the pulling device, The devices are made with lateral longitudinal guides, and the cutting heads are mounted in longitudinal guides by means of hinges and are driven turning in a vertical plane.
