[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a synchronous ejection device for bowl-shaped tiles in a crusher. (Refer to...) Figure 1 and Figure 2 A synchronous ejection device for a crusher's bowl-shaped tile includes a housing 1; the top of the housing 1 has a through slot, and the inner cavity of the housing 1 is provided with an adjustment component 2. The top of the adjustment component 2 passes through the through slot and is equipped with a cylinder 3. The piston rod of the cylinder 3 is bolted to an ejection block 4, and the bottom of the housing 1 is bolted to a base box 5. The inner cavity of the base box 5 is provided with a movable component 6, and the top of the back of the base box 5 is provided with several heat dissipation holes; the cylinder 3 is connected to an external pneumatic system, and the heat dissipation holes ensure the heat dissipation effect of the first motor 21 and the second motor 61.

[0022] Reference Figure 1 and Figure 2The adjusting assembly 2 includes a first motor 21, a connecting shaft 22, a first bevel gear 23, a second bevel gear 24, a lead screw 25, and a moving block 26. The first motor 21 is bolted to the center of the top of the inner cavity of the base box 5. The output shaft of the first motor 21 is fixedly connected to the connecting shaft 22. The top of the connecting shaft 22 extends through the inner cavity of the machine box 1. The top of the surface of the connecting shaft 22 is keyed to the first bevel gear 23. The top of the first bevel gear 23 meshes with the second bevel gear 24. The two sides of the inner cavity of the machine box 1 are rotatably connected to the lead screw 25 through bearings. The inner cavity of the second bevel gear 24 is keyed to the surface of the lead screw 25. The two ends of the lead screw 25 are respectively provided with positive threads and negative threads, and the moving block 26 is threadedly connected to both the positive and negative threads. The top of the moving block 26 passes through a through groove and is bolted to the bottom of the cylinder 3. It can adjust the position of the cylinder 3, thereby adjusting the position of the ejector block 4, so as to facilitate the ejection of the cone assembly and the bowl-shaped tile according to different models of crushers.

[0023] Reference Figure 1 and Figure 3 The portable assembly 6 includes a second motor 61, a threaded rod 62, a threaded block 63, a lifting plate 64, and moving wheels 65. The second motor 61 is bolted to both sides of the top of the inner cavity of the base box 5. The output shaft of the second motor 61 is fixedly connected to the threaded rod 62. The bottom of the threaded rod 62 is rotatably connected to the bottom of the inner cavity of the base box 5 through a bearing. The surface of the threaded rod 62 is threadedly connected to the threaded block 63. The surface of the threaded block 63 is fixedly connected to the lifting plate 64. Moving wheels 65 are installed on both sides of the bottom front and back of the lifting plate 64. The bottom front and back of the bottom of the base box 5 are provided with bottom grooves that cooperate with the moving wheels 65. This makes it convenient to move the device to the position of the crusher during maintenance, avoiding the time and effort of workers to move the device. When in use, the bottom of the base box 5 is in contact with the ground, which improves the stability of the device.

[0024] Reference Figure 1 The bottom of both sides of the base box 5 is bolted to the bottom of the base plate 7, and the bottom of the base plate 7 is bonded with an anti-slip pad 8. The front of the chassis 1 is bolted to the controller for controlling the cylinder 3, the first motor 21 and the second motor 61. This increases the contact area between the bottom of the base box 5 and the ground, and the base plate 7 has a good anti-slip effect, which further improves the stability of the device during use.

[0025] Reference Figure 2 The bottom of the inner cavity of the chassis 1 is provided with a first sliding groove 9 on both sides. The inner cavity of the first sliding groove 9 is slidably connected to a first slider 10. The top of the first slider 10 is bolted to the bottom of the moving block 26. The moving block 26 is limited and assisted in moving, thereby improving the stability of the moving block 26.

[0026] Reference Figure 3The bottom box 5 has a second sliding groove 11 on both sides of the inner cavity. The inner cavity of the second sliding groove 11 is slidably connected to a second slider 12. The opposing side of the second slider 12 is bolted to both sides of the lifting plate 64. The lifting plate 64 is limited and assisted in moving, which improves the stability of the lifting plate 64.

[0027] Working principle: When in use, move the device to the crusher that needs to be disassembled and maintained. Then, the user turns on the second motor 61. The second motor 61 drives the threaded rod 62 to rotate, the threaded rod 62 drives the threaded block 63 to move upward, the threaded block 63 drives the lifting plate 64 to move upward, and thus the lifting plate 64 drives the moving wheel 65 to move upward and retract into the bottom box 5. At this time, the bottom of the bottom box 5 and the bottom of the bottom plate 7 are in contact with the ground. Then, the user turns on the first motor 21. The first motor 21 drives the connecting shaft 22 to rotate, and the connecting shaft 22 drives the first bevel gear 23 to rotate. The first bevel gear 23 drives the second bevel gear 24 to rotate, and thus the second bevel gear 24 drives the lead screw 25 to rotate. The lead screw 25 drives the moving block 26 to move in opposite directions, and thus the moving block 26 drives the cylinder 3 to move in opposite directions. The position of the cylinder 3 can be quickly adjusted according to different crusher models. Then, the cylinder 3 is turned on, and the cylinder 3 drives the ejector block 4 to move upward, lifting the cone assembly and the bowl-shaped tile.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
