Description

Technical Field

[0001] The utility model relates to the technical field of crusher devices, in particular to an impact plate fixing structure of an impact crusher. Background Art

[0002] The impact plate fixing structure of the impact crusher is crucial to its crushing efficiency and service life. It is usually fixed with bolts or wedges. In order to prevent damage to the equipment by hard materials, the impact plate is usually equipped with a spring buffer structure and covered with a wear-resistant lining, such as high manganese steel or alloy steel, to improve impact and wear resistance, thereby ensuring the stability, safety and working efficiency of the crusher.

[0003] After searching, the publication number CN203002423U discloses a structure for fixing the impact plate of an impact crusher. The structure includes an impact frame and an impact plate. The bottom surface of the impact plate is provided with a protrusion, and one of the side surfaces of the protrusion is provided with an inward-concave notch. The impact frame is provided with a groove that matches the protrusion, and a semi-conical head bolt is connected to one side of the groove of the impact plate. The straight edge of the semi-conical head bolt fits with the edge of the groove, and the semi-conical edge fits with the inward-concave notch. The bottom surface of the impact plate fits with the end face of the impact frame. Because the bolts of this utility model are not subject to shear force, they are not prone to breakage. Even if the bolts become loose, the impact plate will not fall off. As long as the equipment is maintained regularly, the reliability of the equipment can be guaranteed. When the fixation is completed, the bottom surface of the impact plate fits with the end face of the impact frame. In this way, the impact force on the impact plate will act directly on the impact frame, which can completely prevent the bolts from breaking due to shear force after loosening, thereby increasing the service life of the equipment's wearing parts and reducing maintenance costs.

[0004] Based on the above patent, by providing a protrusion on the impact plate and a notch on one side of the protrusion, providing a groove on the impact frame, and connecting a semi-conical head bolt, when the two are installed in position, the cone head of the bolt connected to the impact frame will fit into the notch of the impact plate. Under the condition that the groove fits with one side of the protrusion, the cone head of the bolt fits with the notch to achieve the fixation of the impact plate. Because the bolt is not subjected to shear force, this structure is not easy to break, and the impact plate will not fall after the bolt becomes loose. As long as the equipment is maintained regularly, the reliability and safety of the equipment can be guaranteed. Under the premise of completing the fixation, the bottom surface of the impact plate fits with the end face of the impact frame, so that the impact force on the impact plate will act directly on the impact frame, which can completely prevent the bolt from breaking due to shear force after loosening, increase the service life of the equipment's wearing parts, and reduce maintenance costs. At the same time, the connection structure between the impact plate and the impact frame can also adopt different installation methods according to different usage environments, which increases the versatility of the impact plate. However, when installing the impact plate in this patent, it is inconvenient to adjust the installation point position according to the size of the installed impact plate. When the fixed position cannot be adjusted according to the impact plates of different sizes, the gap between the impact plates is too large. The large gap causes the incompletely crushed material to flow back into the crushing chamber, increasing the load of the crusher and causing unnecessary energy consumption and equipment wear.

[0005] To this end, in order to solve the problem that the existing impact frame installation point is inconvenient to adjust according to the size of the impact plate, resulting in excessive gaps between the plates and the complicated installation method of the impact plate, which affects the installation efficiency, a need exists for an impact plate fixing structure for an impact crusher that solves the above problems.

[0038] Example 1: An impact plate fixing structure of an impact crusher, including a crusher shell 1, an inner wall top and an inner wall right end of the crusher shell 1 are both rotatably connected to an electric push rod 2, an impact frame 3 is rotatably connected to the driving end of the electric push rod 2, and the outer wall of the impact frame 3 is rotatably connected to the left end of the rotating column 4. When the electric push rod 2 inside the impact crusher is started, the impact frame 3 will adjust its angle accordingly. At this time, the material in the crusher shell 1 will flow back to the impact frame 3 after the initial crushing by the rotor, and will be further crushed. In order to ensure the efficient operation of the equipment, the angle adjustment of the impact frame 3 can optimize the crushing effect.

[0039] Example 2: The chute plate 8, the inner wall of the chute plate 8 is fixedly connected to the rack plate 10, the outer wall of the bottom end of the adjusting bolt 11 is rotatably connected to the second tooth groove block 22, the outer wall of the bottom end of the second tooth groove block 22 is detachably connected to the outer wall of the rack plate 10, and the outer wall of the second tooth groove block 22 is respectively slidably connected to the inner wall of the front and rear ends of the tooth groove plate 9, the inner wall of the chute plate 8 is slidably connected to the tooth groove plate 9, and the inner wall of the tooth groove plate 9 is slidably connected to a plurality of mounting plates 12, and the bottom end of the mounting plate 12 is rotatably connected to the adjusting rod 13, and the adjusting rod 13 The bottom ends are fixedly connected to the first bevel gear 18 and the second bevel gear 19 is fixedly connected to the opposite end of the threaded rod 20. The second bevel gear 19 and the first bevel gear 18 are meshedly connected. The outer wall of the opposite end of the threaded rod 20 is threadedly connected to the first tooth groove block 21. The outer wall of the opposite end of the first tooth groove block 21 is slidably connected to the front and rear ends of the inner wall of the tooth groove plate 9. Before installation, in order to accurately adjust the installation position of the counterattack plate 5 according to the size of the counterattack plate 5, it is first necessary to adjust the adjustment lever 13 When the adjusting rod 13 is rotated, the first bevel gear 18 starts to rotate and drives the second bevel gear 19 to operate synchronously. At this time, the threaded rod 20 will push the first tooth slot block 21 to move. As the first tooth slot block 21 moves, it will disengage from the tooth slot plate 9, so that the mounting plate 12 can move freely on the tooth slot plate 9 to achieve position adjustment. After the mounting plate 12 is adjusted to a suitable position, it is necessary to reversely rotate the adjusting rod 13 to reinstall the first tooth slot block 21 back to the tooth slot plate 9, thereby ensuring that the mounting plate 12 is fixed in the adjusted position to prevent position displacement. At the same time, by rotating the adjusting bolt 11, the second tooth slot block 22 can be disengaged from the rack plate 10. At this time, the tooth slot plate 9 can also be adjusted accordingly. This operation enables the equipment to be adjusted horizontally and longitudinally to ensure that the installation position meets the dimensional requirements of the impact plate body 5. After the adjustment is completed, the adjusting bolt 11 is reversed to refix the second tooth slot block 22 to the rack plate 10 to ensure the stable position of the entire device.

[0040] Embodiment 3: A fixed tube 14, an adjusting ring 15 is threadedly connected to the outer wall of the fixed tube 14, an adapter ring 16 is rotatably connected to the top of the adjusting ring 15, and a traction block 17 is rotatably connected to the four sides of the outer wall of the top of the adapter ring 16. The top of the traction block 17 is rotatably connected to a fixing claw 23, and the fixing claw 23 is rotatably connected to the four sides of the outer wall of the top of the fixed tube 14 relative to the outer wall of one end. When the device is opened by opening and closing the door 7, it is first necessary to observe the specific position of the adjusting ring 15 in order to perform the disassembly or installation operation. By rotating the adjusting ring 15, it can drive the adapter ring 16, and then the traction block 17 pulls the fixing claw 23 performs a contraction action, which can effectively release the fixation of the impact plate body 5 and make it fall off from the equipment, thereby facilitating the subsequent disassembly work. When installing the impact plate body 5, it is first necessary to accurately connect the impact plate body 5 to the fixing tube 14 to ensure that it is in the correct position. Next, by rotating the adjusting ring 15 in the opposite direction, the fixing claws 23 will open again and tightly grasp the impact plate body 5 to ensure that it is firmly installed in the specified position. At this time, the impact plate body 5 can be smoothly installed in place, which simplifies the disassembly and installation process of the impact plate body 5 and improves the safety and efficiency of the entire operation process.

[0041] As one of the optimized structural designs for Example 1, Figure 1 、 Figure 2 and Figure 8 As shown, the outer wall of the impact frame 3 is rotatably connected to the bottom end of the corresponding docking shell 6 with the opening and closing door 7, and the extrusion block 24 is detachably connected to the outer wall of the opening and closing door 7 at one end. The outer wall of the impact frame 3 is fixedly connected to the docking shell 6, and the inner walls of the front and rear ends of the docking shell 6 are fixedly connected to the return spring 25, and the other end of the return spring 25 is fixedly connected to the extrusion block 24. When the impact plate 5 needs to be disassembled and maintained, it is first necessary to move the extrusion block 24 and remove it from the opening and closing door 7 so that the extrusion block 24 falls off. This can make the opening and closing door 7 open smoothly, providing sufficient operating space for the staff.

[0042] Working principle: When the electric push rod 2 in the impact crusher is controlled to start, the angle of the impact frame 3 is adjusted to allow the fragments crushed by the rotor in the crusher shell 1 to flow back. When the impact plate 5 is disassembled, the extrusion block 24 is moved out to make it fall off from the opening and closing door 7, so that the opening and closing door 7 is opened, which is convenient for the staff to adjust the impact frame 3. After the opening and closing door 7 is opened, the position of the adjustment ring 15 is observed, and the adjustment ring 15 is rotated to make it pass through the adapter ring 16 to let the traction block 17 pull the fixed claw 23 to retract, so that the impact plate 5 falls off, thereby facilitating the disassembly of the impact plate 5. When the impact plate 5 is installed, the impact plate 5 is docked in the fixed pipe 14 and retracted. The reverse rotation of the adjustment ring 15 can make the fixed claw 23 fix the impact plate 5 again, so that the impact plate 5 is convenient for installation. Before installation, when it is necessary to adjust the installation position according to the size of the impact plate body 5, the adjusting rod 13 is rotated to make the first bevel gear 18 drive the second bevel gear 19 and the threaded rod 20 drive the first tooth groove block 21 to move, so that it falls off from the tooth groove plate 9, so that the mounting plate 12 can be adjusted. When the adjustment is appropriate, the adjusting rod 13 is rotated in the opposite direction to make the first tooth groove block 21 re-installed on the tooth groove plate 9, so that the mounting plate 12 is fixed after adjustment, and the adjusting bolt 11 is rotated to make the second tooth groove block 22 fall off from the rack plate 10, so that the tooth groove plate 9 can be adjusted. After the adjusting bolt 11 is moved in the opposite direction, the second tooth groove block 22 can be fixed on the rack plate 10 again, thereby facilitating the horizontal and vertical adjustment of the device and facilitating the adjustment of the installation position according to the size of the impact plate body 5.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
