Description

one

The invention relates to tree-cutting machines and can be used in the forest industry.

Machines for cutting trees are known, including self-propelled chassis, cutting, organ, device for vertical mixing, cutting of trees and a bunker.

A disadvantage of the known machines is that they are ineffective in operation.

The purpose of the invention is to eliminate this drawback.

For this, the device for the vertical movement of cut trees is made as inclined augers located in one vertical plane with different screw pitch, speed vra, yeni and supporting vertical spring wall, and the bunker is installed rotatably in the vertical plane and has walls, one of which is made with an opening, and the other is double-winged, the cutting body, the device for the vertical movement of cut trees and the bunker, are mounted on a common frame equipped with you avnivatelem butts.

FIG. 1 shows a tree cutting machine, side view; in fig. 2 - the same, top view.

The tree cutting machine contains a frame / with wheels 2. Mounted on frame 1

catcher 3 with cutting off working body 4 fixed in its narrowed place, pressure wall, spring-loaded spring 6, hydraulic engine 7, wedge-belt transmission

8. For transporting the cut trees into the bunker 9 on the frame are obliquely mounted in the same plane of the screws 10 and 11, driven by the rotation from the tractor's power take-off shaft 12 and the chain transmission 13. The wheels of the wheels 2 are mounted on spring shock absorbers 14. Fixed at the rear the hinges, the bunker 9 has an entrance opening from the side of the screws, and from the outside a double-wing opening wall 15, each flap

which is closed by a hydraulic cylinder 16. The bunker 9 overturns when it is cleared from a pack of trees by means of a hydraulic cylinder 17. At the back of the frame 1, an equalizer 18 is rigidly fixed,

move the packs of trees away from the wheels of the car, i.e., away from the carriageway.

The operation of the tree cutting machine is carried out as follows.

When the car is moving in reverse, the operator directs the trap 3 to a row, lowers the car to the support wheels 2, turns on the hydraulic motor 7 and the shaft 12 of the power take-off and makes further progress. With

This ensures satisfactory visibility to the operator, since the bunker is offset to the left of the machine's longitudinal axis. When the catcher 3 is thrust on the tree, the latter comes into its constricted part and then falls into the cavity between the screws 10 and 11 and the spring-loaded wall 5. At the same time, the vrash, the working body, cuts the tree, which is screwed to the bunker 9 and reached the opening in the wall of the bunker falls in it. The active ejection of the cut tree into the bunker and the outwardly inclined arrangement of the tree in it is dried, due to some insignificant difference in the speeds of vras, augers and their pitch, as well as an inclined outwards location of the bunker bottom. As you move along the row, the bunker is filled with cut trees. To unload it, the machine stops. In this case, the operator simultaneously turns on the hydraulic cylinders 16 and opens the bunker flaps with them, and the hydraulic cylinder 17 tilts him. Further, the same cylinders hopper is set to its original operating position.

A loose pack of cut trees with leveler 18 with further

moving the car away from the wheels.

As the bunker is filled with cut trees, it is unloaded again, and the working cycle is repeated.

Subject invention

A tree-cutting machine, for example, for thinning of young trees, including a self-propelled chassis, a cutting body, a device for vertical movement of cut trees and a bunker, characterized in that, in order to increase the efficiency of work, the device for vertical movement of cut trees is made inclined augers with different screw pitch and rotation speed and supporting vertical spring-loaded wall located in the same vertical plane, and the bunker is mounted so that it can turn ota in the vertical plane and has walls, one of which is made with an opening, and the other is double-winged, the cutting body, the device for vertical movement of cut trees and the bunker are mounted on a common frame equipped with a leveling device.
