Description

The invention relates to the mining industry, namely to devices for cooling the cutting tool of mining machines. Devices for cooling cutting tools of mining machines are known, including a housing with a cutting disk, pipelines, a pump, and a power source for the working fluid pj. The disadvantage of such devices is that the cooling tool fluid is supplied to the external surface of the tool, which results in contamination of the working fluid. The closest technical solution to the invention is a device for cooling the cutting tool of mining machines, including a body with channels and a mechanism distribution of working fluid, disk cutting rim, annular chamber and water supply channels, water supply element connected to the working power source, liquid zj, disadvantage The known device is a large flow rate which is supplied from the outside of the cutting rim of the disk. The aim of the invention is to increase the cooling efficiency of the tool, I The goal is achieved by the fact that in a device for cooling the cutting tool of mining machines, including a body with channels and a mechanism for distributing the working fluid, a disk with a cutting rim, an annular chamber and water supply channels, the power supply element connected to the power source of the working fluid, the mechanism for distributing the working fluid is made of two flanges having water receiving chambers and water supply channels connected through Nala drive housing and with a stake tsevoy cam disk, wherein a flange is installed between the housing and the disk, and the other - between the housing and vodopodvod conductive element, and the ring va chamber is located at the cutting rim. In addition, in order to provide a closed circulation of the working fluid, the disk, the housing and the flanges are made with drainage channels, and one of the flanges is provided with a drainage element connected to the power source of the working fluid. FIG. 1 shows a device for cooling a cutting tool of a mining machine, general view; in FIG. 2, section A-A in FIG. one; in fig. 3 section bb in fig. 2; in fig. 4 view B in FIG. 1 (pinning method: disc). The device for cooling the cutting tools of the mining machines includes a housing in the form of a two-stage hollow drive shaft 1, a pump with an electric motor 2, a power element 3 connecting the outlet of the pump with a fixed hermetic flange 4 using fittings 5 and 6. The pump is installed on the working power supply fluids in the form of a tank 7. Another hermetic flange 8 is attached to the drive shaft, to which a disk with a cutting rim 10 is attached. The tank is fitted with a drainage element 11, which is connected to the flange 4 by means of fitting 12. M forward drive flange 8 and 9 is located gasket 13 and the flange 4 there are seals 14 and 15 providing, sealing the passage of the working fluid. A design feature of the device is to provide it with elements of an airtight route for supplying fluid to the annular chamber 16 for cooling the disk and draining it into the tank, while the annular chamber is located at the cutting rim 10. The inlet route - (Fig. 3) of the working fluid consists of a water intake chamber 17, .-; Pipes 18, a water intake chamber 19, a channel in the form of a radial groove 20, holes 21 and 22, an annular groove 23, a radial groove 24, an annular groove 25 and a radial groove 26. The removal route (Fig. 4) consists of a channel in the form of radial groove 27, annular grooves 28, radial grooves 29, annular grooves 30, holes 23 and 32, radial grooves 33, holes 34, pipes 35, holes 3,6, chambers 37. The cooling fluid supplied under pressure from the pump 2 enters the chamber 16 through the power element 3 and the supply route. Coolant removal is carried out

through the removal route, the drainage element 11.

To properly orient the disk on the flange 8, one pair of screws 38 is angled, unlike other pairs, located at an angle about, to the axis of the circle (Figure 4). With

In this case, the inlet 22 and outlet 31 of the circle hole coincide, respectively, with the outlet 21 and inlet 32 of the flange 8.

The application of the proposed device allows to reduce the loss of working fluid.
