Description

Coal combines are known with a cutting part made of endless chains or tapes with teeth located on them, moving in a bottom-up direction for cutting and transporting the mineral and mounted on movable supports.

The cutting part 7 of the proposed coal combine is made of three sections, each of which consists of two Gall chains with long axes between chains along the Width of the section, with cam teeth on the axles and scrapers for transporting coal. The contour of the middle section is more extreme, which allows the support and drive parts to enter the cutting part through the protruding space of the contour, without going beyond the outer envelope of the combine.

In FIG. 1 shows a coal miner on the side; FIG. 2 - view from above.

The cutting part 7 of the proposed coal combine (Fig. 1 and 2) consists of three sections 7, 2, 3, and the chains of the Gaul sections 7 and 5 round the drums of the shafts 4 to 5, and the chains of the middle section 2, in addition, the drum of the shaft b, s the purpose of giving a larger contour is to mount the support and drive parts inserted inside the projecting contour so that the parts do not extend beyond the envelope of the cutting part of the combine.

The frame of the cutting part 7 is supported by support rollers 8 on specially profiled planes and provided with scrapers P for taming the steaming coal I with JO reflectors.

At the top of the cutting frame opi.rats on the support arm 77.

The cutting part of the combine is equipped with a motor 72, and the leading part is a motor / 3. From the motor 72, the movement is transmitted by the high-speed chain to the upper shaft of the transmission 75, and from the latter through the friction clutch to the small gear of the upper shaft coupled to the large gear of the lower shaft. On the lower shaft, both gears are fixed on the keys, therefore, from the small gear, movement is transmitted to the large gear, mounted freely on the upper shaft, and hence the drive sprocket linked to the large gear, from the drive sprocket, through the Gall chain, to the shaft of the middle cutting section 2 parts. The cutting part of the middle section 2 serves as a drive chain for the remaining shafts of the cutting part. A conveyor belt 7 is designed for cleaning work. A track 76 serves to move the combine.

During operation, the coal picked up by the scrapers 9 is dumped onto the conveyor J4, and from it onto the conveyor 17 {Fig. 2) or trolley.

h of the invention.

A coal miner with a movable slide for the cutting part, consisting of endless chains with (mounted on them, moving from the bottom upwards to cut and transport coal, characterized in that the cutting part consists of sections I, 2 and 3 (Fig. 2)

of which the chains of section f vi 3 round the drums of shafts 4 and 5, and the chains of the middle section 2 envelope, besides the drum of shafts 4, 5, and the drum of shaft 6, in order to give a larger contour for mounting the supporting and driving parts inserted into the projecting contour so that these parts do not go beyond the size of the cutting part of the combine.
