Detailed Description

The following description is only a preferred embodiment of the present invention, and the protection scope is not limited to the embodiment, and any technical solution that falls under the idea of the present invention should fall within the protection scope of the present invention. It should also be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model.

As shown in fig. 1 to 3, a jaw crusher for quartz stone comprises a crusher body 1, a chute 2 in an inclined state. The material guide groove 2 is arranged above the opening of the crusher body 1, and stone materials to be crushed enter the crusher body 1 along the material guide groove 2. A material baffle 6 is further arranged in the material guide groove 2, and feeding is controlled through movement of the material baffle 6. And because the building stones have certain weight, the power of being used in striker plate 6 is great, and in order to increase the stability of striker plate 6, the inner wall of baffle box 2 both sides is equipped with the spout of cooperation striker plate 6. The inner walls of two sides of the guide chute 2 corresponding to the sliding chute are extended upwards to facilitate the matching of the material baffle 6 and the sliding chute in the moving process.

An extrusion device is also arranged above the opening of the crusher body 1. The extrusion device comprises a support 3, a hydraulic cylinder 4 fixedly arranged on the support 3 and an extrusion block 5. The telescopic link of pneumatic cylinder 4 is down, and the telescopic link bottom has set firmly mounting bracket 7. The extrusion block 5 is arranged below the mounting frame 7, and a plurality of elastic pieces are arranged between the extrusion block 5 and the mounting frame 7. The elastic component is spring 8, and 5 top surfaces of extrusion piece are equipped with a plurality of protruding post 51, and are equipped with the through-hole that supplies protruding post 51 to wear out on the mounting bracket 7, and the tip that mounting bracket 7 was worn out to a plurality of protruding post 51 has set firmly stopper 52, and spring 8 cup joints in the part of protruding post 51 between mounting bracket 7, extrusion piece 5. At first, the extrusion block 5 does not contact stones in the crusher body 1, and the limiting block I52 and the mounting frame 7 are in interference under the action of the spring I8.

Be equipped with the linkage subassembly between striker plate 6 and the pneumatic cylinder 4, striker plate 6 is by pneumatic cylinder 4 drive promptly. The linkage assembly comprises an L-shaped plate 9 and a plurality of second springs 10, and the vertical part of the L-shaped plate 9 is the striker plate 6. The top surface of the L-shaped plate 9 is provided with a plurality of second protruding columns 91, the support 3 is provided with a through hole for the second protruding columns 91 to penetrate out, the end part of the second protruding columns 91 penetrating out of the support 3 is fixedly provided with a second limiting block 92, and the second spring 10 is sleeved on the part of the second protruding columns 91 between the support 3 and the L-shaped plate 9.

Initially, the telescopic rod of hydraulic cylinder 4 is in upper limit, and mounting bracket 7 is contradicted to the horizontal part of L template 9 this moment, makes L template 9 move up, and compression spring two 10 opens striker plate 6. When the stones in the crusher body 1 reach a certain amount, the hydraulic cylinder 4 moves the mounting frame 7 and the extrusion block 5 downwards. The extrusion block 5 collides with stones, and after the extrusion block 5 collides with the stones, the hydraulic cylinder 4 continues to move downwards for a certain distance, so that the distance between the extrusion block 5 and the mounting frame 7 is reduced, and the first spring 8 is compressed. Along with the downward movement of the mounting frame 7, the L-shaped plate 9 moves downward to reset under the action of the second spring 10, the baffle plate 6 blocks the guide chute 2, and feeding is stopped.

As the rock material is crushed, the rock material in the crusher body 1 is reduced, and the extrusion blocks 5 move downwards under the action of the springs I8. Because jaw breaker includes the removal jaw of vertical fixed jaw, slope, and fixed jaw, the interval between the removal jaw reduces gradually, so set the bottom surface of extrusion piece 5 to circular-arc, make things convenient for extrusion piece 5 to remove certain distance between two jaws.

A sensor 53 for measuring the pressure of the first spring 8 is further arranged between the extrusion block 5 and the mounting frame 7 (the sensor 53 is in the prior art, a mounting groove is formed in the extrusion block 5, and the sensor 53 is arranged in the mounting groove). As the stone is crushed, the extrusion block 5 moves downwards, and when the pressure of the elastic piece is reduced to the set value of the sensor 53, the hydraulic cylinder 4 drives the mounting frame 7 to move upwards. When the mounting frame 7 just abuts against the L-shaped plate 9, the material baffle plate 6 still keeps the state of blocking the material guide groove 2, and at the moment, the extrusion block 5 is higher than the material guide groove 2. The hydraulic cylinder 4 continues to move upwards, so that the striker plate 6 moves upwards, the striker plate 6 is opened, and the crusher body 1 is charged. When the crusher body 1 is charged, a certain distance is reserved between the extrusion block 5 and the material guide groove 2, and the extrusion block 5 cannot influence stone materials entering the crusher body 1. After a certain amount of stones are added, the extrusion block 5 moves downwards again to extrude stones, and meanwhile, the material baffle plate 6 restores to baffle materials.
