Description

Technical Field

[0001] This invention relates to the field of jaw crusher technology, and in particular to a jaw crusher and crushing method for nickel-iron alloy production. Background Technology

[0002] A jaw crusher is a device used to crush raw materials used in the production of nickel-iron alloys. When using a jaw crusher, the nickel-iron alloy raw materials to be processed are placed inside the connecting box. The first motor drives the flywheel to rotate through the belt, which in turn drives the connecting cylinder to move on the surface of the eccentric shaft. The moving jaw repeatedly moves back and forth on the stationary jaw under the constraint of the connecting plate, which can crush the raw materials for subsequent processing.

[0003] The inventors discovered in their daily work that jaw crushers still have at least the following problems: When using a jaw crusher, the nickel-iron alloy raw material to be processed is placed inside the connecting box. The first motor drives the flywheel to rotate via a belt, which in turn drives the connecting cylinder to move on the surface of the eccentric shaft. The moving jaw repeatedly moves back and forth on the stationary jaw due to the constraint of the connecting plate. This crushes the raw material for subsequent processing. However, in actual use, since the crushed raw material usually needs to be conveyed out from the bottom of the connecting box by a conveyor belt, the connecting box needs to be manually raised, which is quite troublesome when conveying the processed raw material. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a jaw crusher and crushing method for nickel-iron alloy production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a jaw crusher and crushing method for nickel-iron alloy production, comprising a connecting box, an eccentric shaft rotatably inserted through the top of the connecting box, flywheels fixedly connected to both ends of the eccentric shaft, a first motor provided on one side of the connecting box, a belt sleeved on the output end of the first motor, the belt sleeved on the surface of the flywheels, a connecting cylinder provided on the surface of the eccentric shaft, a movable jaw provided at the bottom of the connecting cylinder, a stationary jaw provided on one side of the inner wall of the connecting box, a connecting plate hinged to one side of the movable jaw, the end of the connecting plate away from the movable jaw being provided on one side of the inner wall of the connecting box, a lifting device provided at the bottom of the connecting box, an adjusting device provided on one side of the connecting box, the lifting device comprising a moving plate, a second motor fixedly connected to the bottom of the moving plate, a threaded rod fixedly connected to the output end of the second motor, the threaded rod threadedly inserted through the bottom of the connecting box, a limit rod fixedly connected to the top of the moving plate, the limit rod slidably inserted through the bottom of the connecting box.

[0006] The effect achieved by the above components is as follows: when using the lifting device, the second motor is started, which drives the threaded rod to rotate. Under the restriction of the limit rod, the connecting box moves away from the moving plate, thereby making the discharge port at the bottom of the connecting box suspended. This makes it easy to set the conveyor belt at the bottom of the discharge port, which facilitates the transportation of crushed raw materials.

[0007] Preferably, the bottom of the connecting box is evenly provided with storage slots, the inner wall of the storage slot is slidably connected to a support plate, the top of the inner wall of the storage slot is fixedly connected to a first damping rod, the bottom of the first damping rod is fixedly connected to the top of the support plate, a first spring is sleeved on the surface of the first damping rod, the top of the first spring is fixedly connected to the top of the inner wall of the storage slot, the end of the first spring near the first damping rod is fixedly connected to the top of the support plate, and a first bolt is threaded through and inserted into one side of the storage slot.

[0008] The effect achieved by the above components is as follows: during the movement of the connecting box, the first spring presses the support plate away from the storage slot, thereby pressing the bottom of the support plate onto the ground. Then, the first bolt is manually controlled to rotate, so that the first bolt is pressed against one side of the support plate. This can confine the support plate inside the storage slot, thus providing a certain degree of support for the connecting box.

[0009] Preferably, a second damping rod is fixedly connected to one side of the connecting box, and a locking frame is fixedly connected to the end of the second damping rod away from the connecting box. The end of the locking frame away from the second damping rod is located at the bottom of the connecting box. A second spring is sleeved on the surface of the second damping rod. One end of the second spring is fixedly connected to one side of the connecting box, and the end of the second spring away from the connecting box is fixedly connected to one side of the locking frame. A rectangular groove is formed at the end of the locking frame away from the second damping rod. A rotating rod is rotatably inserted into the end of the connecting box near the second damping rod. A rectangular plate is fixedly connected to one end of the rotating rod, and the rectangular plate is slidably connected to the inner wall of the rectangular groove.

[0010] The effect achieved by the above components is as follows: before the support plate slides out of the storage slot, the second spring presses the locking frame away from the connecting box, thereby moving the locking frame away from the bottom of the connecting box. In this way, the support plate slides out of the bottom of the connecting box. When the support plate is not in use, the locking frame is manually controlled to be close to one side of the connecting box. At this time, the second spring is compressed, thereby setting the locking frame at the bottom of the storage slot. Then, the rotating rod is manually controlled to rotate, thereby sliding the rectangular plate into the interior of the rectangular slot. This makes it easier to confine the support plate inside the storage slot.

[0011] Preferably, a rectangular block is fixedly connected to one side of the connecting box, a ball bearing is rotatably disposed on the inner wall of the rectangular block, a round rod is fixedly connected to one end of the ball bearing, a sliding cylinder is slidably sleeved at the end of the round rod away from the ball bearing, a second bolt is threaded through the top of the sliding cylinder, a third damping rod is fixedly connected to the top of the rectangular block, a limit sleeve is fixedly connected to the top of the third damping rod, the limit sleeve is slidably sleeved on the top of the rectangular block, a third spring is sleeved on the surface of the third damping rod, one end of the third spring is fixedly connected to the top of the rectangular block, and the end of the third spring near the third damping rod is fixedly connected to the bottom of the limit sleeve.

[0012] The effect achieved by the above components is as follows: the ball bearings are manually controlled to rotate to the appropriate position, and then the sliding cylinder is manually slid on the surface of the round rod. When the sliding cylinder reaches the appropriate position, the second bolt is manually rotated, which causes the second bolt to press against the surface of the round rod. This can effectively extend the length of the round rod. The bottom of the sliding cylinder is set on the ground away from where the conveyor belt needs to be installed. This allows the connecting box to be supported by the sliding cylinder and the round rod. When the round rod is not in use, it is slid into the inside of the sliding cylinder, and then the limiting sleeve is placed on the top of the rectangular block. The limiting sleeve is pulled towards the top of the rectangular block by the third spring, which can effectively restrict the limiting sleeve to the surface of the rectangular block, thereby allowing the round rod to be placed on one side of the connecting box.

[0013] Preferably, the adjusting device includes a sliding block, a groove is provided on one side of the connecting box, the inner wall of the groove is slidably connected to the sliding block, a locking rod is fixedly connected to the end of the sliding block away from the groove, a cylinder is rotatably sleeved on the surface of the locking rod, and limit rings are uniformly fixedly connected to the surface of the locking rod, with two limit rings respectively disposed at both ends of the cylinder.

[0014] The effect achieved by the above components is as follows: when using the adjustment device, the sliding block is manually controlled to slide on the inner wall of the groove, thereby causing the cylinder to be pressed against one side of the inner wall of the belt. In this way, when the belt becomes horizontal due to long-term operation, the belt can still be kept in close contact with the surface of the flywheel, thus not affecting the rotation of the flywheel.

[0015] Preferably, a sliding rod is fixedly connected to the top of the sliding block, the sliding rod is slidably inserted through the top of the sliding groove, a rectangular frame is slidably fitted on the surface of the sliding rod, the bottom of the rectangular frame is fixedly connected to the top of the connecting box, and a third bolt is threaded through one side of the rectangular frame.

[0016] The effect achieved by the above components is as follows: the sliding rod is manually controlled to slide at the top of the groove, and when it slides to the appropriate position, the third bolt is manually controlled to rotate, thereby restricting the sliding rod inside the rectangular frame.

[0017] Preferably, a support frame is fixedly connected to the end of the locking rod away from the sliding block, and the end of the support frame away from the locking rod is located on one side of the connecting box.

[0018] The effect achieved by the above components is that the support frame can support the end of the locking rod away from the sliding block.

[0019] Preferably, a slide rail is fixedly connected to one side of the connecting box, and the interior of the slide rail is slidably connected to the end of the support frame away from the locking rod.

[0020] The effect achieved by the above components is to restrict the support frame at one end of the connecting box, so that the support frame can slide well on the inner wall of the slide rail.

[0021] A crushing method using a jaw crusher for nickel-iron alloy production.

[0022] In this invention, by setting up a lifting device, when using the lifting device, the second motor is started, and the second motor drives the threaded rod to rotate. Under the restriction of the limit rod, the connecting box moves away from the moving plate, thereby making the discharge port set at the bottom of the connecting box suspended. This makes it easy to set the conveyor belt at the bottom of the discharge port, which facilitates the transportation of crushed raw materials. Attached Figure Description

[0033] Example 1, such as Figure 1-9 As shown, a jaw crusher and crushing method for nickel-iron alloy production are disclosed. An eccentric shaft 2 is rotatably inserted through the top of a connecting box 1. Flywheels 3 are fixedly connected to both ends of the eccentric shaft 2. A first motor 4 is installed on one side of the connecting box 1. A belt 5 is fitted onto the output end of the first motor 4 and rests on the surface of the flywheels 3. A connecting cylinder 10 is installed on the surface of the eccentric shaft 2. A movable jaw 6 is installed at the bottom of the connecting cylinder 10. A stationary jaw 7 is installed on one side of the inner wall of the connecting box 1. A connecting plate 11 is hinged to one side of the movable jaw 6. The end away from the moving jaw 6 is set on one side of the inner wall of the connecting box 1. The bottom of the connecting box 1 is equipped with a lifting device 8, and the side of the connecting box 1 is equipped with an adjusting device 9. When using the jaw crusher, the nickel-iron alloy raw material to be processed is placed inside the connecting box 1. The first motor 4 drives the flywheel 3 to rotate through the belt 5, which in turn drives the connecting cylinder 10 to move on the surface of the eccentric shaft 2. The moving jaw 6 repeatedly moves back and forth on the stationary jaw 7 under the restriction of the connecting plate 11, so that the raw material can be crushed for subsequent processing.

[0034] Reference Figures 3 to 6The lifting device 8 includes a movable plate 801. A second motor 802 is fixedly connected to the bottom of the movable plate 801. A threaded rod 803 is fixedly connected to the output end of the second motor 802. The threaded rod 803 is threaded through and inserted into the bottom of the connecting box 1. A limit rod 804 is fixedly connected to the top of the movable plate 801. The limit rod 804 is slidably inserted through and inserted into the bottom of the connecting box 1. When using the lifting device 8, the second motor 802 is started, which drives the threaded rod 803 to rotate. Under the restriction of the limit rod 804, the connecting box 1 moves away from the movable plate 801, thereby suspending the discharge port at the bottom of the connecting box 1. This allows the conveyor belt to be conveniently placed at the bottom of the discharge port, facilitating the transportation of crushed raw materials. The bottom of the connecting box 1 is evenly provided with storage slots 805. A support plate 806 is slidably connected to the inner wall of the storage slot 805. A first damping rod 814 is fixedly connected to the top of the inner wall of the storage slot 805. The bottom of the first damping rod 814 is fixedly connected to the top of the support plate 806. A first spring 815 is sleeved on the surface of the first damping rod 814. The top of the first spring 815 is fixedly connected to the top of the inner wall of the storage slot 805. One end of the first spring 815 near the first damping rod 814 is fixedly connected to the top of the support plate 806. A first bolt 813 is threaded through one side of the storage slot 805. During the movement of the connecting box 1, the first spring 815 presses the support plate 806 away from the storage slot 805, thereby causing the support plate 806 to move. The bottom of the support plate 806 is pressed against the ground. Then, the first bolt 813 is manually rotated, causing it to press against one side of the support plate 806. This confines the support plate 806 within the storage slot 805, providing some support for the connecting box 1. A second damping rod 807 is fixedly connected to one side of the connecting box 1. A locking frame 809 is fixedly connected to the end of the second damping rod 807 away from the connecting box 1. The end of the locking frame 809 away from the second damping rod 807 is located at the bottom of the connecting box 1. A second spring 808 is sleeved on the surface of the second damping rod 807. One end of the second spring 808 is fixedly connected to one side of the connecting box 1. The end of the second spring 808 away from the connecting box 1... The locking frame 809 is fixedly connected to one side of the connecting box 1. A rectangular groove 812 is provided at the end of the locking frame 809 away from the second damping rod 807. A rotating rod 810 is rotatably inserted at the end of the connecting box 1 near the second damping rod 807. A rectangular plate 811 is fixedly connected to one end of the rotating rod 810. The rectangular plate 811 is slidably connected to the inner wall of the rectangular groove 812. Before the support plate 806 is slid out of the storage slot 805, the locking frame 809 is pressed away from the connecting box 1 by the second spring 808, thus moving the locking frame 809 away from the bottom of the connecting box 1. This allows the support plate 806 to slide out of the bottom of the connecting box 1. When the support plate 806 is not in use, the locking frame 809 is manually controlled to be pressed tightly against one side of the connecting box 1. At this time, the second spring 808 is compressed.This allows the card slot frame 809 to be positioned at the bottom of the storage slot 805. Then, the rotating rod 810 is manually controlled to rotate, causing the rectangular plate 811 to slide into the rectangular slot 812. This facilitates confining the support plate 806 within the storage slot 805. A rectangular block 816 is fixedly connected to one side of the connecting box 1. A ball bearing 817 is rotatably mounted on the inner wall of the rectangular block 816. A round rod 818 is fixedly connected to one end of the ball bearing 817. A sliding cylinder 819 is slidably fitted onto the end of the round rod 818 away from the ball bearing 817. A second bolt 820 is threaded through the top of the sliding cylinder 819. A third damping rod 821 is fixedly connected to the top of the rectangular block 816. A limit sleeve 823 is fixedly connected to the top of the third damping rod 821. The limit sleeve 823 slidably fits onto the top of the rectangular block 816. A third spring 822 is fitted onto the surface of the third damping rod 821. One end of the third spring 822 is fixedly connected to the top of the rectangular block 816. The third spring 822 is close to the first... One end of the three-damping rod 821 is fixedly connected to the bottom of the limiting sleeve 823. The ball bearing 817 is manually rotated to a suitable position, and then the sliding cylinder 819 is manually slid across the surface of the round rod 818. When the sliding cylinder 819 reaches the appropriate position, the second bolt 820 is manually rotated, causing it to press against the surface of the round rod 818. This effectively extends the length of the round rod 818. The bottom of the sliding cylinder 819 is positioned away from the ground where the conveyor belt will be installed. The connecting box 1 can be supported by the sliding cylinder 819 and the round rod 818. When the round rod 818 is not in use, it is slid into the sliding cylinder 819, and then the limiting sleeve 823 is fitted onto the top of the rectangular block 816. The third spring 822 pulls the limiting sleeve 823 towards the top of the rectangular block 816, effectively confining the limiting sleeve 823 to the surface of the rectangular block 816, thus positioning the round rod 818 on one side of the connecting box 1.

[0035] Reference Figures 7 to 9The adjusting device 9 includes a sliding block 902. A groove 901 is provided on one side of the connecting box 1. The inner wall of the groove 901 is slidably connected to the sliding block 902. A locking rod 904 is fixedly connected to the end of the sliding block 902 away from the groove 901. A cylinder 905 is rotatably sleeved on the surface of the locking rod 904. Limiting rings 906 are evenly fixedly connected to the surface of the locking rod 904. The two limiting rings 906 are respectively set at both ends of the cylinder 905. When using the adjusting device 9, the sliding block 902 is manually controlled to slide on the inner wall of the groove 901, so that the cylinder 905 is pressed against one side of the inner wall of the belt 5. In this way, when the belt 5 becomes horizontal due to long-term operation, the belt 5 can still be kept in close contact with the surface of the flywheel 3, so as not to affect the rotation of the flywheel 3. A sliding rod 903 is fixedly connected to the top of the sliding block 902. The sliding rod 903 is slidably inserted through the top of the groove 901. The surface of the sliding rod 903 is slidably sleeved with a locking rod 904. A rectangular frame 909 is fixedly connected to the bottom and top of the connecting box 1. A third bolt 910 is threaded through one side of the rectangular frame 909. The sliding rod 903 is manually controlled to slide on the top of the slide groove 901. When it slides to the appropriate position, the third bolt 910 is manually controlled to rotate, thereby restricting the sliding rod 903 inside the rectangular frame 909. A support frame 907 is fixedly connected to the end of the locking rod 904 away from the sliding block 902. The end of the support frame 907 away from the locking rod 904 is located on one side of the connecting box 1. The function of the support frame 907 is to support the end of the locking rod 904 away from the sliding block 902. A slide rail 908 is fixedly connected to one side of the connecting box 1. The interior of the slide rail 908 is slidably connected to the end of the support frame 907 away from the locking rod 904, restricting the support frame 907 at one end of the connecting box 1, so that the support frame 907 can slide well on the inner wall of the slide rail 908.

[0036] Working principle: When using a jaw crusher, the nickel-iron alloy raw material to be processed is placed inside the connecting box 1. The first motor 4 drives the flywheel 3 to rotate via the belt 5, which in turn drives the connecting cylinder 10 to move on the surface of the eccentric shaft 2. Confined by the connecting plate 11, the moving jaw 6 repeatedly moves back and forth onto the stationary jaw 7, thus crushing the raw material for subsequent processing (jaw crushers have been available on the market for a long time, so details are omitted here). When using the lifting device 8, the second motor 802 is started, driving the threaded rod 803 to rotate. Under the constraint of the limit rod 804, the connecting box 1 moves away from the moving plate 801. During the movement of the connecting box 1, the first spring 815 pushes it away from the receiving groove 805. Press the support plate 806, causing its bottom to press against the ground. Then, manually control the first bolt 813 to rotate, pressing it against one side of the support plate 806. This confines the support plate 806 within the storage slot 805, providing some support for the connecting box 1. Before sliding the support plate 806 out of the storage slot 805, the second spring 808 presses the locking frame 809 away from the bottom of the connecting box 1, causing the locking frame 809 to move away from the bottom of the connecting box 1. The support plate 806 then slides out of the bottom of the connecting box 1. Then, manually control the ball bearing 817 to rotate to the appropriate position, and then manually slide the sliding cylinder 819 on the surface of the round rod 818. When the sliding cylinder... When 819 slides to the appropriate position, manually rotate the second bolt 820, causing it to press against the surface of the round rod 818. This effectively extends the length of the round rod 818, positioning the bottom of the sliding cylinder 819 away from the ground where the conveyor belt will be installed. The sliding cylinder 819 and the round rod 818 then support the connecting box 1, suspending the discharge port at the bottom of the connecting box 1. This allows for easy placement of the conveyor belt at the bottom of the discharge port, facilitating the transport of crushed raw materials. When the support plate 806 is not in use, manually control the locking frame 809 to be flush against one side of the connecting box 1. At this time, the second spring 808 is compressed, causing the locking frame 809 to be positioned at the bottom of the receiving trough 805. Then, manually control the rotating rod 810 to rotate, thereby sliding the rectangular plate 811 into the interior of the rectangular groove 812. This facilitates the confinement of the support plate 806 within the storage groove 805. When the round rod 818 is not in use, slide the round rod 818 into the sliding cylinder 819, and then place the limiting sleeve 823 on the top of the rectangular block 816. The limiting sleeve 823 is pulled towards the top of the rectangular block 816 by the third spring 822, which effectively confines the limiting sleeve 823 to the surface of the rectangular block 816, thus allowing the round rod 818 to be positioned on one side of the connecting box 1. When using the adjusting device 9, manually control the sliding rod 903 to slide at the top of the sliding groove 901. When it slides to the appropriate position, manually control the rotation of the third bolt 910.This confines the sliding rod 903 within the rectangular frame 909, causing the cylinder 905 to be pressed against one side of the inner wall of the belt 5. This ensures that even if the belt 5 becomes horizontal due to prolonged operation, it remains firmly attached to the surface of the flywheel 3, preventing any interference with its rotation. The support frame 907 supports the end of the locking rod 904 furthest from the sliding block 902.

[0037] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
