Description

The invention relates to the forest industry and can be used to destroy stumps after the forest.

A device for destroying obstacles, made in the form of a two-feather cutter, has cutters on each arm, each cutter being installed on its own radius. The cutters are installed in one row with a uniform pitch and intervals corresponding to the width of the cutter, on each arm of the cutter so that the intervals between the cutters on one shoulder correspond to the incisors on the other shoulder 1.

The disadvantages of this device are the power loss, dynamic overload of the incisors and the vibration of the entire device.

It is also known a device for destroying remnants of woody vegetation, comprising a disk-shaped body, on one of the side surfaces of which are incisors, and an actuator 2.

A disadvantage of this device is that, when operating below ground level, the destruction of destroyed wood and loosened soil mass can occur only through the annular gap between the walls of the well formed by the incisors at the periphery of the disk and the disk of the tool. This leads to poor performance, increased wear and power.

The purpose of the invention is to increase work efficiency.

The goal is achieved by the fact that the disk is equipped with curved cleaning blades mounted on the same surface as the cutters and deflecting blades that are placed on the other surface of the disk at an angle to it and the direction of rotation of the disk.

FIG. 1 shows the device, top view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 shows a section B-B in FIG. 3; in fig. 5 is a cross-section of the FIG. one; in fig. 6 - device with a drive, general view.

A device for destroying residues of woody vegetation comprises a disc 1 with a central pre-drill (2), incisors (3), straight-line stripping knives (4), curvilinear stripping blades (5) and deflecting blades (6) set at an angle to the plane of the disc and the direction of rotation. The incisors 7, placed at the ends of the disc beams, are mounted obliquely so that their cutting part extends beyond the envelope 8 of the rotating disc, describing envelope 9. The disc is mounted on the shaft 10 in the housing 11 and connected to the drive motor 12. The housing 11 is connected by means of an bracket 13 with boom base machine. The bottomhole space under the disk 1 includes the rear sight 14 (intact stump or rock), the destroyed mass of soil and soil 15, the gap 16 between the destroyed mass and the lower plane of the disk. A portion of the destroyed mass 17, cut off by stripping knives, is located in the space above the disc. The incisors on the disk are located each on its own radius so that during rotation they cut through concentric grooves ,. close enough adjacent to one another. As a result, the entire surface of the slab across the diameter of the disk is uniformly destroyed. The incisors on the rays of the disk (Fig. 1) are arranged so that the moments from the cutting forces are balanced relative to its axis of turn.

The operation of the device is as follows.

When the working tool is thrust on the face, the incisors 3 and 7 destroy the rear sight 14. The soil mass 15 formed with the destroyed one is between the still untouched 14 and the disk 1 .;

When the disk is rotated, the adjoining destroyed mass of curvilinear cleaning knives 5 continuously mixes from the center of rotation to the periphery, where under the influence of rectilinear cleaning knives 4 it moves upward into the space above the disk. Further, the part of the destroyed mass 17 under the influence of the deviation of the lower blades 6 is ejected upwards and to the sides from the zone of action of the working organ.

As a result, between the destroyed soil 15 and the disk 1, the gap 16 is constantly maintained, thereby providing the working body is thrust over the face and the material is not overgrown. In addition to the axial feed, the presence of the angled cutters 7 also permits the lateral feed of the tool.

The device is effective in destroying stumps and reduces the amount of earthwork. Aa
