[0002] A jaw crusher is a device used to crush the raw materials used in the production of nickel-iron alloy. 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 a belt, which in turn drives the connecting cylinder to move on the surface of the eccentric shaft. Under the restriction of the connecting plate, the movable jaw repeatedly moves back and forth to the static jaw, so that the raw materials can be crushed for subsequent processing.

[0003] The inventor found in his daily work that the jaw crusher still has at least the following problems: when using the jaw crusher, the nickel-iron alloy raw material to be processed is placed inside the connecting box, and 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 movable jaw repeatedly moves back and forth to the static jaw under the restriction of the connecting plate, so that the raw material can be broken up for subsequent processing. However, in actual use, because the broken raw materials generally need to be transported out from the bottom of the connecting box with a conveyor belt, it is necessary to manually raise the connecting box, which is more troublesome when transporting the processed raw materials.

When the adjusting device 9 is used, the sliding block 902 is manually controlled to slide on the inner wall of the sliding groove 901, so that the cylinder 905 is squeezed on one side of the inner wall of the belt 5, so that when the belt 5 is horizontal due to long-term work, the belt 5 can also be closely attached to the surface of the flywheel 3, thereby not affecting the rotation of the flywheel 3. The top of the sliding block 902 is fixedly connected to a sliding rod 903, and the sliding rod 903 slides through and is inserted in the top of the sliding groove 901. The surface of the sliding rod 903 is slidably sleeved with Rectangular frame 909, the bottom of rectangular frame 909 is fixedly connected to the top of connection box 1, one side of rectangular frame 909 is threadedly inserted with a third bolt 910, the sliding rod 903 is manually controlled to slide on the top of the slide groove 901, and when it slides to a suitable position, the third bolt 910 is manually controlled to rotate, thereby limiting the sliding rod 903 inside the rectangular frame 909, and the end of the positioning rod 904 away from the sliding block 902 is fixedly connected to the support frame 907, and the end of the support frame 907 away from the positioning rod 904 is arranged on one side of the connection box 1, and the function of the support frame 907 can support the end of the positioning rod 904 away from the sliding block 902, and one side of the connection box 1 is fixedly connected to a slide rail 908, and the interior of the slide rail 908 is slidably connected to the end of the support frame 907 away from the positioning rod 904, and the support frame 907 is arranged on one end of the connection box 1 to limit it, so that the support frame 907 can slide well on the inner wall of the slide rail 908.

[0028] Working principle: 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, and then drives the connecting cylinder 10 to move on the surface of the eccentric shaft 2. Under the restriction of the connecting plate 11, the movable jaw 6 repeatedly moves back and forth to the static jaw 7, so that the raw material can be broken up for subsequent processing (jaw crushers have been circulating on the market for a long time, so I won’t go into details here). When using the lifting device 8, start the second motor 802, and drive the threaded rod 803 to rotate through the second motor 802. Under the restriction of the limit rod 804, the connecting box 1 is away from the movable plate 801. During the movement of the connecting box 1, the first spring 815 squeezes in the direction away from the storage groove 805. The support plate 806 is pressed, so that the bottom of the support plate 806 is pressed on the ground, and then the first bolt 813 is manually controlled to rotate so that the first bolt 813 is pressed on one side of the support plate 806, so that the support plate 806 can be restricted inside the storage groove 805, so that the connection box 1 can be supported to a certain extent by the support plate 806, and before the support plate 806 slides out of the storage groove 805, the second spring 808 is used to press the positioning frame 809 in the direction away from the connection box 1, so that the positioning frame 809 is away from the bottom of the connection box 1, so that the support plate 806 slides out of the bottom of the connection box 1, and then the ball bearing 817 is manually controlled to rotate to a suitable position, and then the manual sliding cylinder 819 slides on the surface of the round rod 818. When the sliding cylinder When 819 slides to the appropriate position, the second bolt 820 is manually rotated, so that the second bolt 820 is squeezed on the surface of the round rod 818, which can well extend the length of the round rod 818 and set the bottom of the sliding cylinder 819 on the ground away from the need to install the conveyor belt. In this way, the connecting box 1 can be supported by the sliding cylinder 819 and the round rod 818, so that the discharge port set at the bottom of the connecting box 1 is suspended in the air, so that the conveyor belt can be conveniently set at the bottom of the discharge port, which is convenient for transporting the crushed raw materials. When the support plate 806 is not used, the positioning frame 809 is manually controlled to be close to one side of the connecting box 1. At this time, the second spring 808 is compressed, so that the positioning frame 809 is set at the bottom of the storage groove 805, and then After that, the rotating rod 810 is manually controlled to rotate, and then the rectangular plate 811 is slid into the inside of the rectangular groove 812, which makes it easy to limit the support plate 806 in the storage groove 805. When the round rod 818 is not in use, the round rod 818 is slid into the inside of the sliding cylinder 819, and then the limiting sleeve 823 is sleeved on the top of the rectangular block 816, and the limiting sleeve 823 is pulled toward the top of the rectangular block 816 by the third spring 822. In this way, the limiting sleeve 823 can be well limited to the surface of the rectangular block 816, so that the round rod 818 is set on one side of the connecting box 1. When using the adjustment device 9, the sliding rod 903 is manually controlled to slide on the top of the sliding groove 901. When it slides to a suitable position, the third bolt 910 is manually controlled to rotate.The sliding rod 903 is then restricted inside the rectangular frame 909, 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 work, the belt 5 can still be closely attached to the surface of the flywheel 3, and thus will not affect the rotation of the flywheel 3. The support frame 907 can support the end of the positioning rod 904 away from the sliding block 902.

[0029] It should be noted that all damping rods in this case are retractable dampers that can absorb energy during the retraction process.
