SU52958A1 - Combine for excavation of mine workings - Google Patents

Description

The proposed harvester aims to excavate the mines by cutting the bottomhole rock using a rotary milling cutter. The combine is presented in several different forms of execution.

In a schematic drawing of FIG. Figures 1 and 2 depict two vertical sections of a combine for penetrating verticular uiaxTs of rectangular section; FIG. 3 and 4 - two vertical sections of a combine for driving vertical round shafts; FIG. 5 and 6 - VIEW from the side and from above of the combine for driving horizontal and inclined mine workings; FIG. 7 and 8 are side and top views of another embodiment of the combine for the same purpose.

The working part of the combine is a teeth-equipped 2 milling cutter /, placed on the bars 3 and serving as a drum for the teeth-supplied chains. In order to move the drum cutter / during the combine operation from one wall of the mine to the other, the bars 3 are made of rotary 3 vertical planes about the shaft 5, driven into rotation

wheel 6 through gears 7, 7 and a worm gear 8. To rotate the cutter-drum / and the bar chains 4 there is an electric motor 9, which transmits its rotation to the upper wheels 10 chains through a worm gear //. The fully described working part of the combine is fastened inside frame J2, which is suspended inside screw frame J3 by means of a screw, // which, for vertical movement of frame J3, is rotated via worm gear / 5. To remove the sludge cutter formed during operation of the rock cutter, there are tubes 16 connected by flexible hoses / 7 to a pump JS directly connected to an electric motor / R.

In order to install the combine into the work site, a mine is prepared in the usual way in b-8 m depth with the corresponding section and a combine is mounted in this mine. To do this, one or several winches are installed on the Surfaces on the corresponding ropes, from the Blant Aban Winch. NaPG - azlu "yuyushchy frame / J

set in a strictly vertical position and secured to the walls of the excavation by pressing 20 so that this frame remains stationary. If there is no groundwater in the bottom, then artificially water is introduced into it from the surface through pipe 2 / to such a level that during operation of the mill / in its extreme positions, the suction tubes J6 are immersed in liquid. Having started up the electric motor that drives the chain 4 with teeth, and consequently, the cutter-drum / by means of the screw 14, the whole unit / 2 mounted in the frame / 2 is lowered to the bottom, approximately 10-15 cm, by means of the steering wheel 6 begin to drive the bars 3 to the desired razierosis production. As soon as the cutter-drum has reached its extreme position, HS stops its work, again by means of a screw / 7 lower the inner frame with the unit by the amount of a new notch, i.e. 10-15 cm, after which the cutter-drum with the same steering wheel again move in the opposite direction to the opposite wall of the excavation. After all the engine speeds of the ving 14 have been consumed, the operation of the unit is stopped and the outer frame 13 is lowered and the screw 14 is brought back to its initial position (Fig. I and 2). The sludge of the rock that is formed as a result of the operation of the mill is removed from the bottom by means of suction tubes 16, which are secured in such a way that their ends are at a certain constant height above the mill drum. These tubes, when connected with bars, accompany the cutter-drum with all its floors (x. B; pi; some of the tubes 16 are connected to the pump intake via flexible hoses. Thus, by pumping the sludge through the pipe 22, it is pumped out to the surface. From the intake, water is replenished from the surface through pipe 21. As the combine moves, temporary and permanent fastening of the ground is produced.

The above described combine harvests for driving vertical shafts of rectangular section. Day of penetration

mines of circular cross section and for cutting at the same time the rock over the entire area of the bottom of the mill, the drum is made to rotate around a vertical axis (Fig. 3 and 4). To this end, the working part of the combine, consisting of a milling cutter-drum-on / with teeth 2 and a chain 4 with teeth driven by an electric motor 9 through a worm gear //, is fixed in an internal cylinder 23 located inside suspended on ropes 24 cylinder 25 rotatably in this latter. To rotate the inner cylinder 23, the round axis of the vertical axis is a ring comb 26. supported by means of rollers 27 on the upper part of the internal cylinder 23 and provided with tides, which engage the inner cylinder in such a way that when the internal cylinder rotates, the ring comb 26 does not can rotate, but can freely descend along with the internal CYLINDER 23 on which it rests. The ring is engaged with a 2S gear wheel, supported by a bracket 29 fixed on the inner cylinder and driven by electric motors. To lower the inner drum, the gear nut 30 sits on the shaft 31. H-rezabarab / is made in the form of two truncated cones (Fig. 3: facing the middle of the drum with narrow ends. The tubes / b and pump 18, driven by an electric motor 9. The discharge tube 22 is equipped with a gland 32 serving to rotate it freely as the inner cylinder 25 rotates. To install the combine into the work site, as in the first case, prepare the shaft 6-8 .4 in the usual way. with the corresponding sechgniem them therein and mounted harvester is suspended on the ropes and held winches mounted on the surface. The whole assembly usgangvlivayut in a strictly vertical position by an external tsilpndro 25 and secured by clamps to the wall of the shaft 20. Then hammer zzl vzyut water ;;

The rest of the device combine like the previous combine.

After assembling the entire combine in the prepared development (in the usual way) and installing it in a certain direction, the supporting columns are installed. Turning on the electric motor 9 drives the entire unit. By pressing the jack continuously, the combine moves to the face of the slab and, thus, the combine works without interruption until the jack screw is completely used, after which the screw is retracted, the columns 36 are rearranged, and the work cycle continues. The bushing, obtained as a result of milling, is removed by augers, and the milled rock is thrown into the transverse screw 39 with the help of a pick-up 42.

The subject matter of the invention.
