Specific embodiment
It elaborates with reference to the accompanying drawing to the utility model.
A kind of screening plant of stone crusher as shown in Figs 1-4, including lithotripsy apparatus 1 and screening plant, the screening plant
In the casing 2 of the lower part of the lithotripsy apparatus 1, the screening plant includes removing thick slag screen fraction and sizing screening portion
Point.
The thick slag screen fraction is located at the stone crusher lower part, and the thick slag screen fraction includes griddle network selection 3, institute
Griddle network selection 3 is stated to be horizontally placed in casing 2 and be located at below 1 discharge port of lithotripsy apparatus, the intermediate lower surface of griddle network selection 3
It is fixed with a connecting rod 4,4 both ends of connecting rod are inserted into casing 2 respectively and can be freely rotated in casing 2, keep it big
Hole sizer network selection 3 can rotate inside casing 2 around connecting rod 4;One end setting and the connecting rod 4 of the griddle network selection 3 are hung down
Straight link block 5, the link block 5 pass through casing 2 and connect with the first hydraulic stem 7 in the first convex frame 6 on 2 outer wall of casing,
Hydraulic stem 7 is constantly flexible, so that one end of griddle network selection 3 constantly moves up and down, is conducive in griddle network selection 3
Bulk rubble rolls out outside casing 2, and the link block 5 can move up and down under the action of hydraulic stem 7 in the first convex frame 6,
Place that link block 5 stretches out casing 2 be provided with one just enable link block 5 hydraulic stem 7 it is flexible under move up and down
Strip-shaped hole.The other end of griddle network selection 3 is pierced by casing 2, and the lower part of the griddle network selection 3 of 2 outer wall of casing is provided with for branch
The the second convex frame 8 for being fixed on 2 outer wall of casing for supportting griddle network selection 3, is provided with the first spring 9 in the convex frame, and described first
9 one end of spring is fixedly connected with the second convex 8 bottom of frame, and the other end is connect by cylindrical piece 10 with griddle network selection 3, the cylinder
Block 10 can free in and out in the second convex frame 8, and the one end for stretching out casing 2 is always low one end, enable bulk rubble from low
End rolls out, and with spring supporting griddle network selection 3 is constantly shaken under the action of hydraulic stem 7 and rubble weight, so that bulk
Rubble is more easier to be discharged.
The sizing screening part includes aperture screening net 13, and the aperture screening net 13 is located at the griddle network selection 3
Lower part, a rectangular cylinder 12 being fixed on 2 inner wall of casing, the rectangular cylinder 12 is arranged in the lower part of aperture screening net 13
Upper surface is provided with several uniform grooves 14, and the second spring 15 in the groove 14 is fixedly linked with strut 16 and to connect
Strut 16 can freely move up and down in groove 14 with the flexible of second spring 15, and 16 top of the strut connection inclination is set
The edge for the aperture screening net 13 set, the height of the strut 16 are set according to the inclination conditions of aperture filter screen, the aperture
Transmitting device 17 is arranged in the low side end for screening net 13.When the rubble that top is fallen makes aperture screening net 13 in strut 16 and the
Constantly shaken under the action of two springs 15, keep its screening more abundant, larger rubble send transmitting device 17 send out, compared with small crushed stone from
It is drained in the device of 2 lower part of casing on aperture screening net 13.
Further, screening plant top is provided with two baffles on 2 inner wall of casing of lithotripsy apparatus 1,
Change the direction and slow down the speed that rubble is thrown away that rubble is thrown away.
Further, the open end of the groove 14 is equipped with a rubber ring 19 covered on strut 16, so that dust is not
It can enter in groove 14.
Further, third spring 20 is set between the hydraulic stem 7 and the link block 5.Increase griddle network selection 3
Shake ability enables what bulk rubble impurity was more easier to tumble away.
Further, hinged one piece of first baffle 11 in the opening passed through on casing 2 for griddle network selection 3.So that disorderly flying
The rubble casing 2 that will not fly out cause security risk, bulk rubble opens first baffle 11 to casing 2 by the gravity of itself
Outside.
