Description

The invention relates to loading machines consisting of a horizontal shaft provided with toothed discs and cutters for conducting a side vertical cutting and bars for collecting coal.

In the proposed loading machine, the extreme gear disks, one of which, depending on the direction, works near the bottom plane, are mounted on a horizontal shaft, placed inside the hollow shaft bearing the intermediate gear disks; Both of these shafts are driven in rotation with a different number of revolutions.

In FIG. 1 is a side view of the loader; FIG. 2 shows it from above; FIG. 3 - view of the transmission to the horizontal shafts.

The movement of the loading machine L when operating in the face of lava is carried out along the path of the cutting-in machine B. The machine can work in hollow falling seams, in the left and right sides of the lava, from the bottom upwards through the rebellion of the seam, as well as in horizontal layers.

in the scooping mechanism of the machine, mounted on the swivel brackets, the intermediate disks 2 are rigidly mounted on a horizontal hollow shaft 1 (Fig. 1 and 2). The discs have slots for inserting the cutting teeth 3 in them. The teeth are placed at different angles relative to the plane of rotation of the discs so that there is a distance of about 100 mm between the teeth of the adjacent discs. The extreme gear disks 6 of the mechanism, one of which operates near the bottom plane, are mounted on a special shaft 7 (Fig. 3) passing inside the hollow shaft. The purpose of this device is to give the disc 6 a greater number of revolutions than the intermediate discs 2, since this disc has to work under the conditions of an unbroken slab (s), while the intermediate discs 2 operate in a destroyed angle. The shaft 1, in the place of its passage inside the casing 5, is cut into two parts to enable the rotation of the shaft 7, regardless of the rotation of the shaft 1, through the conical
