Description

Technical Field

[0001] The utility model relates to the technical field of ore processing, in particular to an ore crushing and stirring device. Background Technique

[0002] After the ore is mined, it is generally large in volume. In order to facilitate transportation, a crushing device is needed to crush the ore.

[0003] The current crushing device usually crushes the ore through two crushing rolls. However, for the crushed ore, the size difference may be relatively large. Subsequently, the staff still needs to screen out the large pieces of ore for re-crushing. And currently, when some crushing devices are in use, the efficiency of crushing the ore only by the extrusion of the two crushing rolls is relatively poor. Some large pieces of ore are easily piled up near the crushing rolls, and the smaller ore is stacked on top of the larger ore, making it difficult to be quickly crushed. Therefore, it is easy to affect the overall crushing efficiency of the ore. In addition, the smaller ore will increase the weight that the crushing rolls need to bear, thus affecting the service life of the crushing rolls. Content of the Utility Model

The spline shaft 4 movably penetrates the operating frame 7. Both ends of the crushing roller 5 are rotatably connected to both sides of the inner wall of the operating frame 7. The bottom of the operating frame 7 is in contact with the top of the net plate 10. A second belt pulley 9 is fixedly sleeved on the surface of the adjusting mechanism 6.

The two first belt pulleys 8 are connected by a belt drive. The two second belt pulleys 9 are connected by a belt drive. Feeding grooves and discharging grooves are respectively opened at the upper and lower parts of the surface of the fixed frame 1. A partition plate 11 is fixedly connected to the bottom of the inner wall of the feeding groove. The surface of the partition plate 11 is slidably matched with the surface of the operating frame 7. The partition plate 11 can block one side of the fixed frame 1 to reduce the possibility that the ore directly falls onto the top of the net plate 10 during feeding. A cross plate 12 is arranged at the top of the operating frame 7. Stirring mechanisms 13 are installed on both sides of the top of the cross plate 12. A rack plate 14 is slidably matched with the top of the cross plate 12. Both ends of the rack plate 14 are in contact with both sides of the inner wall of the fixed frame 1. T-shaped plates 15 are fixedly connected to both ends of the rack plate 14. Sliding grooves 16 are respectively opened on both sides of the inner wall of the fixed frame 1. The surface of the T-shaped plate 15 is in contact with the inner wall of the sliding groove 16. The cooperation of the T-shaped plate 15 and the sliding groove 16 can increase the stability of the rack plate 14 during lifting and moving. A U-shaped plate 17 is fixedly connected to the top of the cross plate 12. The top of the rack plate 14 is in contact with the top of the inner wall of the U-shaped plate 17.

Accordingly, it is convenient for the operating frame 7 to drive the cross plate 12 to move horizontally when moving.

[0027] The driving mechanism 3 includes a motor 31, a driving shaft 32, and a gear disk 33. The motor 31 is fixedly connected to the surface of the L-shaped plate 2.

At this time, the other driving shaft 32 can be driven to rotate through gear transmission. The two spline shafts 4 drive the two crushing rollers 5 to rotate at the same time, so as to crush the ore inside the working frame 7. One first belt pulley 8 is fixedly sleeved on the surface of one driving shaft 32.

When one extension rod 62 rotates, at this time, with the cooperation of the second belt pulley 9 and the belt, the other extension rod 62 rotates accordingly. The two lead screws 61 rotate in the same direction at the same time, so as to drive the working frame 7 to move horizontally through the adjusting plate 63. The movement of the working frame 7 is convenient for adjusting the state of the ore below inside the working frame 7, so that the small crushed ore can fall through the mesh plate 10. The other first belt pulley 8 is fixedly sleeved on the surface of one extension rod 62.

[0029] The stirring mechanism 13 includes a rotating shaft 131, stirring rods 132, and a spur gear 133. The rotating shaft 131 rotates through the cross plate 12.

The spur gear 133 is fixedly sleeved on the surface of the rotating shaft 131. The top and bottom of the spur gear 133 are respectively in contact with the top of the inner wall of the C-shaped plate 17 and the top of the cross plate 12. The rack plate 14 is meshed with the spur gear 133. When the cross plate 12 moves with the working frame 7, the stirring mechanism 13 moves accordingly. At this time, the cooperation of the spur gear 133 and the rack plate 14 can drive the rotating shaft 131 to rotate. The stirring rods 132 rotate accordingly to stir the ore blocks inside the working frame 7, so that the ore blocks can better contact the surface of the crushing roller 5. Accordingly, it is convenient for the crushing roller 5 to better crush the ore blocks.

[0030] The lifting mechanism 18 includes a hydraulic rod 181, a lifting plate 182, and a guide plate 183. The hydraulic rod 181 is fixedly connected to the top of the fixed frame 1. The piston rod of the hydraulic rod 181 slidably penetrates the top of the fixed frame 1. The lifting plate 182 is fixedly connected to the piston rod of the hydraulic rod 181. The bottom of the lifting plate 182 contacts the top of the U-shaped plate 17. The number of guide plates 183 is two, and the two guide plates 183 are respectively fixedly connected to both sides of the top of the U-shaped plate 17. Guide grooves 19 are formed on both sides of the top of the lifting plate 182. The surface of the guide plate 183 contacts the inner wall of the guide groove 19. When the staff starts the hydraulic rod 181, the lifting plate 182 and the guide plate 183 cooperate to drive the cross plate 12 to lift through the U-shaped plate 17, so as to feed the inside of the working frame 7.

[0031] Working principle: When the device is in use, the staff can first start the hydraulic rod 181. The lifting plate 182 drives the U-shaped plate 17 to lift through the guide plate 183, and the cross plate 12 rises accordingly. At this time, the rack plate 14 rises with the cross plate 12, and the top of the working frame 7 is exposed. The staff can put the ore into the inside of the working frame 7. After that, the staff can start the lifting mechanism 18, and the lifting mechanism 18 can perform reverse operation to seal the top of the working frame 7 with the cross plate 12 and the limit frame 20. Then the staff starts the motor 31. With the cooperation of the gear disc 33, the two drive shafts 32 rotate simultaneously, and the spline shaft 4 drives the crushing roller 5 to rotate, so as to crush the ore inside the working frame 7 through the crushing roller 5. At the same time, with the cooperation of the first pulley 8 and the belt and the second pulley 9 and the belt, the extension rod 62 drives the lead screw 61 to rotate, and then drives the working frame 7 to move through the adjusting plate 63, so that the shaking generated when the working frame 7 moves can screen out the small pieces of ore generated by crushing inside the working frame 7 through the mesh plate 10. During the movement of the working frame 7, the spur gear 133 and the rack plate 14 cooperate to drive the rotating shaft 131 to rotate, and the stirring rod 132 rotates with the rotating shaft 131 to stir the ore inside the working frame 7, so that some of the ore with smaller dimensions can better fall between the two crushing rollers 5, thereby facilitating the improvement of the efficiency of the ore crushing operation.
