[0016] Example 1
[0017] like Figures 1 to 4As shown, this utility model discloses a ore sample crushing device. The technical solution adopted includes a crushing box 1, with support legs 22 fixedly installed at the four corners of the bottom of the crushing box 1. An arc-shaped impact chamber 2 is set at the center of the top of the crushing box 1. A trapezoidal platform 16 is set at the bottom left end of the inner side of the arc-shaped impact chamber 2. Arc-shaped guide rods 7 are set at the front and rear ends of the trapezoidal platform 16, and the left and right ends of the arc-shaped guide rods 7 are fixedly connected to the upper surface and the right side surface of the trapezoidal platform 16, respectively. A rotating plate 8 is slidably installed on the arc-shaped guide rods 7. An auxiliary component is set at the bottom left end of the rotating plate 8. The auxiliary component consists of a fixed plate 10, an electromagnet 11, and a counterweight block 12. The fixed plate 10 is fixedly installed at the bottom left end of the inner side of the arc-shaped impact chamber 2. The top of the fixed plate 10... An electromagnet 11 is fixedly installed on the rotating plate 8. The electromagnet 11 is magnetically connected to a counterweight block 12 located at the bottom left of the rotating plate 8. One end of the rotating plate 8 is fixedly connected to a connecting shaft 6 rotatably mounted at the center of the arc-shaped impact chamber 2. The front and rear ends of the connecting shaft 6 are respectively driven by drive units 5 located on the front and rear sides of the arc-shaped impact chamber 2. The drive unit 5 includes a first motor 51, a threaded rod 52, a moving frame 53, a rack 54, a gear 55, a second motor 56, a slide 57, a slider 58, and a fixing block 59. There are two sets of fixing blocks 59, which are symmetrically arranged on the bottom of the front and rear sides of the arc-shaped impact chamber 2. A threaded rod 52 is rotatably mounted between each set of fixing blocks 59. One end of the threaded rod 52 is fixedly connected to the left end of the fixing block 59. The output shaft of the first motor 51 is fixedly connected. A movable frame 53 is threadedly mounted on the threaded rod 52. The movable frame 53 has an "I"-shaped structure. A slider 58 in the middle of the movable frame 53 is slidably connected to a groove 57 on the outer side of the arc-shaped impact chamber 2. A rack 54 is rotatably mounted on the top of the movable frame 53. The right end of the rack 54 is fixedly connected to the output shaft of the second motor 56 fixedly mounted on the right side of the arc-shaped impact chamber 2. The rack 54 meshes with the teeth of gears 55 at the front and rear ends of the connecting shaft 6. By starting the first motor 51, the first motor 51 drives the threaded rod 52 to move the movable frame 53. The rack 54 on the movable frame 53 drives the gears 55 to rotate the connecting shaft 6, causing the connecting shaft to move. The rotating plate 8 slides along the arc-shaped guide rod 7, compressing the compression spring 15 until the electromagnet 11 magnetically connects and fixes the counterweight block 12. Then, the second motor 56 is controlled to rotate the rack 54, causing the teeth on the rack 54 to misalign with the teeth on the gear 55. Finally, the electromagnet 11 is turned off. When the counterweight block 12 loses its magnetic connection and fixation by the electromagnet 11, the rotating plate 8 slides rapidly along the arc-shaped guide rod 7 under the force of the compression spring 15. As the rotating plate 8 slides rapidly, the first crushing hammer 9 on it begins to impact and crush the ore sample. Compression springs 15 are respectively installed at the front and rear ends of the bottom of the rotating plate 8, and are respectively fitted onto the outer side of the arc-shaped guide rod 7.The bottom of the compression spring 15 is fixedly connected to the upper surface of the trapezoidal platform 16, and the top of the compression spring 15 is in movable contact with the bottom of the rotating plate 8. A first crushing hammer 9 is arranged in an array on the top left end of the rotating plate 8. A pushing assembly is provided on the left end of a partition plate located in the middle of the inner side of the crushing box 1, and the pushing assembly is fixedly connected to a connecting plate 13 located on the right end of the partition plate. Second crushing hammers 14 are arranged in an array at equal intervals on the right side of the connecting plate 13. The first crushing hammers 9 and the second crushing hammers 14 are staggered. The first crushing hammers 9... The ore sample is staggered with the second crushing hammer 14 to ensure that it is impacted and crushed from all directions during the crushing process. A discharge box door 4 is located in front of the connecting plate 13 and is rotatably mounted in the middle of the front side of the crushing box 1. A receiving frame 24 is located below the discharge port at the bottom right end of the crushing box 1 and is slidably mounted in the tracks 23 located at the left and right ends of the discharge port. The pushing assembly consists of a slide rod 17, a buffer plate 18, an L-shaped plate 19, an electric telescopic rod 20, and a pull block 21. The slide rod 17... The slide rod 17 is slidably installed in a sliding hole in the center of the partition. The right end of the slide rod 17 is fixedly connected to the left side of the connecting plate 13. A buffer plate 18 is fixedly installed on the left end of the slide rod 17. L-shaped plates 19 are welded to the front and rear ends of the bottom of the buffer plate 18, respectively. Electric telescopic rods 20 are respectively installed on the right end of the L-shaped plates 19. The electric telescopic rods 20 are fixedly installed on the left side of the partition. Pull blocks 21 are fixedly installed on the telescopic ends of the electric telescopic rods 20, and the pull blocks 21 are movably locked onto the top of the L-shaped plates 19. By activating the electric telescopic rods 20, the slide rods 17 can be moved to the left side of the partition. The pull block 21 at the telescopic end of the electric telescopic rod 20 pulls the L-shaped plate 19, causing the buffer plate 18 and the slide rod 17 to move. This causes the connecting plate 13 at the other end of the slide rod 17 to push the crushed ore towards the discharge port, allowing the ore to fall into the receiving frame 24, completing the entire crushing and discharge process. The system also includes a controller 3, which is located at the front left end of the crushing box 1. The output of the controller 3 is electrically connected to the input of the first motor 51, the second motor 56, the electromagnet 11, and the electric telescopic rod 20. The input of the controller 3 is electrically connected to the output of an external power supply.
[0018] The working principle of this utility model is as follows: First, open the feeding box door 4 and place the ore sample to be crushed into the crushing box 1, near the side of the connecting plate 13 and the second crushing hammer 14. Then close the box door 4. Next, turn off the electromagnet 11 via the controller 3. When the counterweight block 12 loses the magnetic connection and fixation of the electromagnet 11, under the force of the compression spring 15, the rotating plate 8 slides rapidly along the arc-shaped guide rod 7. As the rotating plate 8 slides rapidly, the first crushing hammer 9 on it will begin to impact the ore sample. Simultaneously, because the first crushing hammer 9 and the second crushing hammer 14 are staggered, it ensures that the ore sample can be impacted and crushed from all directions during the crushing process. If secondary crushing of the ore sample is required, the controller 3 simultaneously starts the first motor 51, which drives the moving frame 53 to move via the threaded rod 52. The rack 54 drives the gear 55 to rotate the connecting shaft 6, causing the connecting shaft 6 to slide the rotating plate 8 along the arc-shaped guide rod 7 and compress the compression spring 15 until the electromagnet 11 re-magnetically connects and fixes the counterweight block 12. Then, by controlling the second motor 56 to rotate the rack 54, the teeth on the rack 54 are misaligned with the teeth on the gear 55. Finally, the electromagnet 11 is turned off, and the above crushing process is repeated. When it is necessary to remove the crushed ore sample, the rotating plate 8 is fixed back to its original position, and the electromagnet 11 fixes the rotating plate 8 again. Then, the controller 3 starts the electric telescopic rod 20, causing the pull block 21 at the telescopic end of the electric telescopic rod 20 to pull the L-shaped plate 19, which in turn moves the buffer plate 18 and the slide rod 17. The connecting plate 13 at the other end of the slide rod 17 pushes the crushed ore towards the discharge port, so that the ore falls into the receiving frame 24, completing the entire crushing and discharge process.
