Summary of the invention
Technical problem: for solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of underground liquid pressure type coal gangues automation selection equipment, realizes coal directly separated with under waste shaft.
Technical scheme: underground liquid pressure type coal gangues automation selection equipment of the present utility model, symmetrical position on housing is provided with two identical material bins, two inner sides, housing left and right are welded with respectively many group engaging lugs, between adjacent two engaging lugs, by connecting pin, connect a pressing plate, housing is each side arranged six pressing plates, while falling fragmentation without material, pressing plate and vertical direction angle β are about 30 degree, bearing is housed on axle, bearing is contained on the housing of front and back, cam is arranged on axle, two drive units that explosion-proof buncher rotates as two of left and right axle, drive respectively two of left and right axle to do counterclockwise and clockwise rotatablely moving, each pressing plate is supported by the piston rod being connected on hydraulic cylinder, each hydraulic cylinder is connected on housing by the bearing pin on its shell, two elastic network(s)s screening opposite position below pressing plate in housing and cam that is not in tilted layout, elasticity mesh screen upper end is connected to pull bar lower end, lower end is welded on discharging opening, housing is by the stent support of below, fortune coal ribbon conveyer is arranged in elasticity mesh screen below, two fortune cash ribbon conveyers are arranged in two discharging opening belows, cam outline is round, cam face is processed into tooth bar shape, collision impact when elasticity mesh screen falls by coal and spoil is as exciting force, separately do not establish power set.
Beneficial effect: the utility model can directly carry out separated with spoil by the coal that is greater than 50mm in down-hole, make spoil not go out well, the spoil sub-electing can be directly used in the filling in goaf, thereby reduce the freight that spoil goes out well, automation degree of equipment is high, simple in structure, take that volume is little, easy accessibility, free from environmental pollution.
Accompanying drawing explanation
Fig. 1 is main TV structure figure of the present utility model.
Fig. 2 is the A-A sectional structure chart of accompanying drawing 1.
In figure: 1-fortune cash ribbon conveyer, 2-discharging opening, 3-pressing plate, 4-engaging lug, 5-housing, 6-cam, 7-pull bar, 8-material bin, 9-piston rod, 10-bearing pin, 11-hydraulic cylinder, 12-elasticity mesh screen, 13-support, 14-fortune coal ribbon conveyer, 15-connecting pin, 16-bearing, 17-axle, the explosion-proof buncher of 18-.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:
Underground liquid pressure type coal gangues automation selection equipment of the present utility model, mainly by fortune cash ribbon conveyer 1, discharging opening 2, pressing plate 3, engaging lug 4, housing 5, cam 6, pull bar 7, material bin 8, piston rod 9, hydraulic cylinder 11, elasticity mesh screen 12, support 13, fortune coal ribbon conveyer 14, axle 17, explosion-proof buncher 18 forms.
Symmetrical position on described housing 5 is provided with two identical material bins 8, housing 5 left and right sides inwalls are welded with respectively many group engaging lugs 4, between adjacent two engaging lugs 4, by connecting pin 15, connect a pressing plate 3, housing 5 is each side arranged six pressing plates 3, while falling fragmentation without material, pressing plate 3 is about 30 degree with vertical direction angle β, bearing 16 is housed on axle 17, bearing 16 is contained on the housing 5 of front and back, cam 6 is arranged on axle 17, two drive units that explosion-proof buncher 18 rotates as two of left and right axle 17, drive respectively two of left and right axle 17 to do counterclockwise and clockwise rotatablely moving, each pressing plate 3 is supported by the piston rod 9 being connected on hydraulic cylinder 11, each hydraulic cylinder 11 is connected on housing 5 by the bearing pin 10 on its shell, two elasticity mesh screens 12 opposite position below pressing plate 3 in housing 5 and cam 6 that is in tilted layout respectively, elasticity mesh screen 12 upper ends are connected to pull bar 7 lower ends, lower end is welded on discharging opening 2, housing 5 is supported by the support 13 of below.
Described fortune coal ribbon conveyer 14 is arranged in elasticity mesh screen 12 belows, two fortune cash ribbon conveyers 1 are arranged in two discharging opening 2 belows, cam 6 outlines are round, cam 6 Surface Machining become tooth bar shape, collision impact when elasticity mesh screen 12 falls by coal and spoil, as exciting force, is not separately established power set.
Operation principle: material is fallen between cam 6 and pressing plate 3 by material bin 8, thereby explosion-proof buncher 18 driving shaft 17 rotations are with the rotation of moving cam 6, material is at the cam 6 of rotation and the extruding lower stress of pressing plate 3, when force value surpasses the crushing force that coal sets, coal is crushed, when force value surpasses the crushing force certain limit that coal sets, piston rod 9 retractions in hydraulic cylinder 11, left and right pressing plate 3 rotates to clockwise and counter clockwise direction respectively under material extruding, thereby spoil is not crushed, when pressing plate 3 rotates to vertical direction, piston rod 9 in hydraulic cylinder 11 extends, pressing plate 3 is got back to initial position under the effect of piston rod 9, wait for action next time, the coal crushing and do not have crushed spoil to fall on the elasticity mesh screen 12 of arranged beneath, elasticity mesh screen 12 produces up-down vibration in the vibration of coal and spoil collision impact under as exciting force effect, thereby the coal that makes fritter is fallen on the fortune coal ribbon conveyer 14 of elasticity mesh screen 12 belows, do not have crushed bulk spoil to be slipped to fortune cash ribbon conveyer 1 from discharging opening 2.
