Description

Technical Field

[0001] This utility model relates to the field of cast steel parts technology, specifically to a high-strength cast steel part for a jaw crusher. Background Technology

[0002] Jaw crushers, also known as jaw breakers or tiger's mouth crushers, are crushing machines consisting of a crushing chamber formed by two jaw plates: a moving jaw and a stationary jaw. They mimic the jaw movements of an animal to crush materials. They are simple in structure, easy to manufacture, and reliable in operation. They are widely used in mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries for crushing various ores and large materials. The maximum compressive strength of the material to be crushed is 320 MPa. Jaw crushers are mainly used as coarse and medium crushers in mining, building materials, and infrastructure sectors. They are classified into large, medium, and small types according to the width of the feed opening. Currently, jaw crushers require assembly using cast steel parts during installation and operation. However, long-term operation easily leads to wear and tear on the plates, and their low strength makes them unsuitable for long-term use. Therefore, there is an urgent need to design a jaw crusher using high-strength cast steel parts to solve this problem.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0022] A high-strength cast steel component for a jaw crusher includes a plate 1. A chamber 2 is formed on one side of the plate 1, and a through hole is formed on the other side of the top of the plate 1, with the inner side of the through hole communicating with the inner side of the chamber 2. A riser 3 is attached to the top of the plate 1 at the through hole. A connecting seat 4 is installed on the top of the plate 1 at the side of the through hole. An extension plate 5 is attached to the top of the connecting seat 4, and the other end of the extension plate 5 is fixedly connected to the outer wall of the riser 3. The extension plate 5 and the connecting seat 4 are engaged by a connecting mechanism, which includes a splicing component, a dragging component, and a covering component. The splicing component is used to lock the riser 3, the dragging component is used to unlock it, and the covering component is used to protect the dragging component. In use, the device can lock the riser 3 through the splicing component, unlock the dragging component, and protect the dragging component through the covering component. The structure is simple and easy to operate. When disassembling and maintaining the device, the operator does not need to twist each set of bolts one by one, reducing the workload of the operator and facilitating the operator to quickly disassemble and perform maintenance, further improving the practicality of the device.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the splicing assembly includes a reset pad 6 installed at the bottom of the extension plate 5. The reset pad 6 has an installation hole inside. A splicing block 7 is installed on one side of the bottom of the extension plate 5 at the installation hole on the reset pad 6. A splicing groove is opened on one side of the top of the connecting seat 4 corresponding to the installation hole. The splicing groove and the splicing block 7 are slidably connected. The reset pad 6 is a rubber reset pad. First, the riser 3 is placed above the plate 1 so that the extension plate 5 contacts the surface of the connecting seat 4. Then, the riser 3 and the extension plate 5 are pressed down to compress the reset pad 6, so that the splicing block 7 slides into the inner side of the installation groove along the splicing groove, so that the splicing block 7 and the spring block 11 come into contact and fit together, so that the two sets of opposing inclined surfaces 13 press against each other, forcing the first limiting block 9 to slide and press the first spring 10 inside the first limiting groove, while stretching the second spring 12.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the connecting seat 4 has an installation groove on one side of the splicing groove. A limit seat 8 is installed on one side of the inner wall of the installation groove. A first limit groove is formed on one side of the limit seat 8. A first limit block 9 is slidably connected to the inner side of the first limit groove. A first spring 10 is installed between one side of the first limit block 9 and the inner wall of the first limit groove. A spring block 11 is installed at one end of the first limit block 9. A spring groove is formed on one side of the spring block 11. A second spring 12 is installed between the inner side of the spring groove and the inner wall of the installation groove. Both ends of 11 and the assembly block 7 have mutually fitting inclined surfaces 13. Then, the pressing continues, causing the inclined surfaces 13 on the assembly block 7 to press against the slope 17. The locking plate 15 presses the torsion spring 16 back to the inside of the locking groove until the abutment groove is pushed to the locking groove. Then, the torsion spring 16 drives the locking plate 15 to pop out to the inside of the abutment groove. After the pressing of the riser 3 and the extension plate 5 stops, the reset pad 6 will rebound a short distance, so that the inner wall of the abutment groove abuts against one end of the locking plate 15, locking the riser 3.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the spring-loaded block 11 has a locking groove on its inclined surface 13. A connecting rod 14 is rotatably connected to one end of the inner wall of the locking groove. A locking plate 15 is sleeved on the outer side of the connecting rod 14. A torsion spring 16 is installed between one end of the connecting rod 14 and the inner wall of the locking groove. A slope 17 is formed on one side of the locking plate 15, and the slope 17 fits against the inclined surface 13. The assembly block 7 has an abutment groove on its inclined surface 13. The dragging assembly includes a groove on one side of the spring-loaded block 11, and a movable rod 18 is installed on the inner wall of the groove. An extension groove is formed on one side of the mounting groove inside the connecting seat 4. The seat 4 has a movable groove between the extension groove and the mounting groove. The movable groove is slidably connected to the movable rod 18. The end of the movable rod 18 extending into the extension groove is rotatably connected to a pull ring 19. Furthermore, when repairing or replacing the riser 3, the operator can hold the pull ring 19 to drive the movable rod 18 to slide inside the movable groove, causing the spring block 11 to retract actively. After the locking plate 15 is disengaged from the inner side of the abutment groove, the resistance disappears and the reset pad 6 will fully spring back, causing the abutment groove to move upward. At this time, releasing the pull ring 19 will not reposition it. Then the riser 3 can be picked up for inspection and maintenance.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the cover assembly includes a cover groove on the outer wall of the connecting seat 4. The inner side of the cover groove is connected to the inner side of the extension groove. Both sides of the inner wall of the cover groove are provided with translation grooves 20. A cover plate 21 is slidably connected to the inner side of the cover groove. A drag groove is provided on one side of the cover plate 21. Translation blocks are installed at both ends of the cover plate 21. The translation blocks are slidably connected to the translation groove 20. A magnetic block 22 is embedded at one end of the cover plate 21. An iron block that attracts the magnetic block 22 is embedded in the inner wall of the cover groove. Furthermore, after the riser 3 and the plate 1 are combined, the cover plate 21 can be slid by holding the drag groove with a finger. When sliding, the translation block also slides inside the translation groove 20 to ensure the smooth movement of the cover plate 21. After the worker completely covers the inner side of the extension groove with the pull ring 19, the magnetic block 22 can attract the iron block to position the cover plate 21 to prevent accidental contact by personnel after assembly.

[0027] The implementation principle of a high-strength cast steel part for a jaw crusher according to an embodiment of this application is as follows: First, the riser 3 is placed above the plate 1, so that the extension plate 5 contacts the surface of the connecting seat 4. Then, the riser 3 and the extension plate 5 are pressed downward to compress the reset pad 6, allowing the splicing block 7 to slide into the inner side of the mounting groove along the splicing groove, so that the splicing block 7 and the spring block 11 come into contact and fit together, so that the two sets of opposing inclined surfaces 13 press against each other, forcing the first limiting block 9 to slide and press the first spring 10 inside the first limiting groove, while stretching the second spring 12. The pressing continues, causing the inclined surface 13 on the splicing block 7 to press against the slope surface 17. The locking plate 15 presses the torsion spring 16 back to the inner side of the locking groove until the abutment groove is pushed to the locking groove. Then, the torsion spring 16 drives the locking plate 15 to pop out to the inner side of the abutment groove. After the pressing of the riser 3 and the extension plate 5 stops, the reset pad 6 will rebound a short distance. Make the inner wall of the abutment groove abut against one end of the locking plate 15 to lock the riser 3. When repairing or replacing the riser 3, the worker can hold the pull ring 19 to drive the movable rod 18 to slide inside the movable groove, which will drive the spring block 11 to retract actively. After the locking plate 15 is separated from the inner side of the abutment groove, the resistance will disappear and the reset pad 6 will fully rebound, causing the abutment groove to move upward. At this time, releasing the pull ring 19 will not reposition it. Then the riser 3 can be picked up for inspection and maintenance. After the riser 3 is combined with the plate 1, the finger can hold the drag groove to drive the cover plate 21 to slide. When sliding, the translation block also slides inside the translation groove 20 to ensure the smooth movement of the cover plate 21. After the worker completely covers the inner side of the extension groove with the pull ring 19, the magnetic block 22 can attract the iron block to position the cover plate 21 to prevent personnel from accidentally touching it after assembly.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
