Abstract
The utility model discloses an underground coal leaking hole discharging valve, which relates to mine equipment. The discharging valve comprises shafts, sector boards, material supporting boards, gears and a wrench. A discharging port connected with a hopper is a rectangular pipe, and two ends of two shafts are respectively installed on the discharging port through bearing seats. The two gears with the same modulo and tooth number are meshed with each other and are installed at one ends of the two shafts through a key I and a nut. Two of the four sector boards are respectively fixed on the inner sides of the two gears, and the other two sector boards are respectively installed at the other ends of the shafts through a connecting board and a key II. The lower edge openings of the sector boards are formed into arc shapes, the arc material supporting boards are welded to the lower edge openings of the two laterally symmetrical sector boards. The wrench is fixed on the outer sides of the sector boards. The symmetrical central line of the sector boards penetrates through the center of a circle of a shaft connected with the sector boards. The arc center of the material supporting boards is concentric with a shaft connected with the material supporting boards.
Description
Technical field
The utility model relates to a kind of mining equiment, is specifically related under a kind of coal mine to use when leaking coal eye discharge refuse
Coal eye discharge gate is leaked in the down-hole.
Background technique
When slope construction got into the second phase, because skip bucket can not be immediately following harrowing directly discharge refuse of cash machine back, transportation range was far away, influences construction speed under the coal mine.When promoting on the pit shaft horizontal position, just can above the skip bucket operation, make a call to one and leak the coal eye main as driving face, as interim conveying spoil passage and waste bin temporarily, discharge gate need be installed in the outlet port of leakage coal eye.The discharge gate that uses at present, when leaking coal intraocular spoil more for a long time, because spoil material resistance is big, the discharge opening valve can not effectively be opened or close; Additional valves can only play the effect of opening or closing make and break, can't close control and leak the cash amount.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of down-hole to leak coal eye discharge gate, utilizes fan-shaped double leaf valve as spigot baffle, and two pitch wheels drive the double leaf valves and are synchronized with the movement, opened manually or close.
The utility model is realized through following technological scheme: coal eye discharge gate is leaked in a kind of down-hole, and it comprises: hopper, discharge opening and be installed in the discharge gate on the discharge opening.Described discharge gate, it comprises: axle, sector, retainer plate, gear and spanner.Described discharge opening is a rectangular tube, and the rectangular tube upper end is connected with hopper.Described axle is two, and two axle two ends are installed on the discharge opening through bearing support respectively; Two of described gears, the modulus of two gears is identical, the number of teeth equates and be meshing with each other, and two gears are installed in an end of two axles respectively through key I and nut.Described sector is four, and wherein two sectors are separately fixed at the inboard of two gears; It is solid that other two sectors are installed in the other end of two axles through connecting plate and key II respectively; The following mouth of sector is made into arc, described retainer plate, be arc plate, and retainer plate is welded on the following mouth of symmetrical two sectors.Described spanner is fixed on the outside of sector.
The symmetrical center line of described sector is through being attached thereto the center of circle of the axle that connects.
The arc core of described retainer plate circular arc and the axle concentric that is attached thereto.
The beneficial effect of the utility model is:
1, effectively controls discharge opening and leaked the cash amount, improved discharge refuse efficient.
2, the spigot baffle resistance is little during switch, and parts are not fragile, long service life.
3, the unlatching of manual control valve or close, easy to operate.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain
Fig. 1 is to the utility model structural representation.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the discharging view.
Fig. 4 is mounting point, a utility model down-hole schematic representation.
Among the figure: 1, hopper, 2, gear, 3, nut, 4, the key I, 5, bearing support; 6, axle, 7, spanner, 8, sector, 9, retainer plate, 10, discharge opening; 11, connecting plate, 12, the key II, 13, mine car, 14, go up drift; 15, leak the coal eye, 16, leak coal eye discharge gate, 17, skip bucket, 18, the main tunnel that promotes.
Formula is done in practical implementation
Like Fig. 1,2, shown in 3: coal eye discharge gate is leaked in a kind of down-hole, and it comprises: hopper 1, discharge opening 10 and be installed in the discharge gate on the discharge opening 10.It is characterized in that: described discharge gate, it comprises: axle 6, sector 8, retainer plate 9, gear 2 and spanner 7.Described discharge opening 10 is the rectangular tube shape, and the rectangular tube upper end is connected with hopper 1.Described axle 6 is two, and two axle 6 two ends are installed on the discharge opening 10 through bearing support 5 respectively.2 two of described gears, the modulus of two gears 2 is identical, the number of teeth equates and be meshing with each other, and two gears 2 are installed in an end of two axles 6 respectively through key I 2 and nut 3.Described sector 8 is four, and wherein two sectors 8 are separately fixed at the inboard of two gears 2; It is solid that other two sectors 8 are installed in the other end of two axles 6 through connecting plate 11 and key II 12 respectively.Following mouthful of sector 8 is made into arc, and described retainer plate 9 is an arc plate, and retainer plate 9 is welded on following mouthful of symmetrical two sectors 8; Described spanner 7 is fixed on the outside of sector 8.
As shown in Figure 4: as when driving face is in the bottom of drift 14 in main lifting tunnel 18, just can above skip bucket 17 operations, makes a call to one and leak coal eye 15, as interim conveying spoil passage and interim waste bin.During last drift 14 discharge refuses, directly be poured on spoil Lou in the coal eye 15 with mine car 13, when skip bucket 17 was below leaking coal eye 1, Open valve leaked spoil, throttle down when skip bucket 17 is filled, and a car is loaded in wait.
Like Fig. 1,2, shown in 3: when skip bucket 17 is below leaking coal eye 1, manually upwards move handle 7, under the effect of two gears 2; About two sectors 8 outwards rotate simultaneously, two retainer plates 9 progressively separate, the spoil in the hopper 1 flows out from the slit of retainer plate 9; Fall in the skip bucket 17 of below, when the spoil in the skip bucket 1 is filled, oppositely move handle 7; Two retainer plates 9 close up, and the spoil in the discharge opening 10 is held, and realize throttle down.Fully charged skip bucket 17 transports spoil from the main tunnel 18 that promotes.
Because the symmetrical center line of sector 8 is through being attached thereto the center of circle of the axle 6 that connects; The arc core of retainer plate 9 circular arcs and axle 6 concentrics that are attached thereto when retainer plate 9 rotates, are not done promotion upwards to the material on the retainer plate 9 in moving process, retainer plate 9 resistance to motion are little, valve opening, close merrily and lightheartedly, and parts are not fragile, long service life.
The monolateral gear engagement of present embodiment also can adopt limit bidentate wheel engagement, transmission better effects if at the two ends of axle 6.
