Abstract

The invention relates to the mining industry and can be used in the excavation of workings. The goal is to increase the efficiency of the process of destruction of rocks by reducing the energy intensity of cutting and reducing wear of the cutters. The actuator includes a carrier 1, on the beams 2 of which rotating disks 3 and 6 are mounted. The cutters 4 on the disk 3 are installed at different distances from the axis of rotation 5. The cutters 7 on the disk 6 are installed at equal distances from the axis of rotation 8. At Moving the combine in the direction of the bottom 9, the disks 3 and 6, rotating around the axes 5 and 8, under the action of the carrier 1, make a portable rotation and the cutters 4 and 7 chip the chips from the bottom surface. The use of two disks on the planetary executive body, one of which (disk 3) is fixed eccentrically with a variable radius, and the other (disk 6) with a constant, provides not only a change in the angle of contact of the disks with the array, but also a different position of the bottom chest. The area of plots processed by discs depends on the magnitude of eccentricity. 12 il.

The planetary executive body consists of a carrier 1 with rays 2, on which is placed the cutting disk 3, the cutters 4 of which are mounted on different

At the initial moment, each of the cutting discs 3 and 6 with the incisors 4 and 7 destroys the array in its zone. After turning the carrier 1 at 180 °, the cutting disk 3 enters the area previously treated with the cutting disk 6, and the cutting disk 6 enters the area previously treated with the cutting disk 3. At the same time (Fig. 2) the cutting disk 3 with its smaller radius in the direction of the bottom 9, and the cutting disc b enters the zone previously processed by the large radius of the cutting disk 3, therefore in this position the cutters 4 and 7 (not shown in Fig. 2-10) of the cutting disks 3 and 6 are not in contact with the face 9.

This position of 20 each corresponds to the position in FIG. 2, after which the executive body will again pass the positions shown in FIGS. 2-10.

The use on a planetary executive body to destroy an array of two cutting disks, one of which with a variable radius and the other with a constant, provides not only a change in the contact angles of the cutting disks with the array, but also a different position of the chest. .

This leads to the fact that each of the cutting disks processes the face in its section (Fig. 11): the cutting disk 3, the cutters of which are located at different distances from the axis of rotation, processes the face 9 only in sections 11, and the cutting the disk 6, the cutters of which are installed at equal distances from the axis of rotation, 50 processes the face 9 only in sections 10.

In addition, a decrease in the contact angle of the cutters with the massif increases their path5 during which they do not cut the face and, therefore, cool, which makes it possible to increase the wear resistance of the cutting tool. .
