Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses building stones screening grinder. Referring to fig. 1 and 2, a stone screening grinder includes a classifying grinder body 1, and a coarse screening device 2 is provided at a feed port of the classifying grinder body 1. The coarse screening device 2 is arranged right above the feeding hole, so that the aggregates need to be screened by the coarse screening device 2 when entering the grading and grinding device body 1.

Referring to fig. 1 and 2, the coarse screening device 2 includes a support frame 21 fixed on the grading grinding device body 1, a hinge groove is formed in the support frame 21, a vibration frame 22 is hinged in the hinge groove, a hinge shaft 23 inserted into the hinge groove is arranged on the vibration frame 22, and the vibration frame 22 can rotate around the hinge shaft 23. The fixed plate is arranged on the grading grinding device body 1, far away from one side of the hinge shaft 23, of the vibration frame 22, the jacking hydraulic cylinder 24 is hinged to the fixed plate, a piston rod of the jacking hydraulic cylinder 24 is hinged to the vibration frame 22, and therefore the jacking hydraulic cylinder 24 can drive the vibration frame 22 to rotate and incline.

Referring to fig. 1 and 2, a screening plate 25 is fixed in the vibration frame 22, so that aggregates can enter the grading and grinding device body 1 after being screened by the screening plate 25 during feeding, and further, the aggregates with large diameters can be prevented from entering and being incapable of being ground. Lead to the time for prevent once only putting in too much aggregate, lead to screening board 25 to be blockked up, the below of vibrations board is provided with at least one shock dynamo 26 for shock dynamo 26 can drive vibrations frame 22 and screening board 25 and shake, and then guarantees that the aggregate on the screening board 25 can not pile up and can normally drop. When the aggregate with large diameter piled on the screening plate 25 is more, the jacking hydraulic cylinder 24 can be started to drive the vibrating frame 22 and the screening plate 25 to be wholly inclined, so that the aggregate on the screening plate 25 can slide down.

Referring to fig. 1 and 3, a receiving guide rail 3 is disposed below one side of the sieving plate 25 in the pouring direction, and a crushing assembly 4 is disposed below the receiving guide rail 3, so that large-diameter aggregates poured from the sieving plate 25 can be poured into the crushing assembly 4. Broken subassembly 4 includes broken case 41 that open-top set up, is fixed with broken pneumatic cylinder 42 on the lateral wall of broken case 41, and the piston rod of broken pneumatic cylinder 42 stretches into inside and fixedly connected with breaker 43 of broken case 41 to make broken pneumatic cylinder 42 can drive breaker 43 and remove, and then make breaker 43 extrude the aggregate, thereby make the aggregate broken, so that retrieve and grind again. Meanwhile, in order to ensure the crushing quality, a plurality of conical crushing nails 44 are arranged on one surface of the crushing plate 43, which is far away from the crushing hydraulic cylinder 42, so that the aggregate can be nailed by the crushing nails 44, and the aggregate can be conveniently crushed. Simultaneously in order to facilitate discharging the aggregate, be provided with a plurality of bin outlets 45 on the crushing case 41 diapire, and then make the aggregate of smaller size can directly discharge, only need to set up crushing case 41 when using and put.

The implementation principle of the stone screening and grinding device in the embodiment of the application is as follows: aggregate need pass through when the material loading and sieve the board 25 and sieve the back and just can get into hierarchical grinder body 1, and then prevent that the aggregate of major diameter from getting into and can't grind. The vibration motor 26 can drive the vibration frame 22 and the screening plate 25 to vibrate, so as to ensure that aggregates on the screening plate 25 cannot be stacked and can normally fall off. When a large amount of large-diameter aggregates are accumulated on the screening plate 25, the jacking hydraulic cylinder 24 can be started to drive the vibrating frame 22 and the screening plate 25 to be integrally inclined, so that the aggregates on the screening plate 25 can slide down. The crushing hydraulic cylinder 42 can drive the crushing plate 43 to move, so that the crushing plate 43 extrudes the aggregate, and the aggregate is crushed, so that the aggregate is recycled and ground.
