DETAILED DESCRIPTION

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1

[0030] Reference Figures 1-4 A toothed plate includes: a body 1. An eccentric shaft 2 is rotatably mounted on the body 1, and a movable jaw 3 is rotatably mounted on the eccentric shaft 2. The movable jaw 3 can move accordingly as the eccentric shaft 2 rotates.

[0031] On one side of the movable jaw 3, a slot 11 is provided. A movable toothed plate 5 is disposed within this slot 11, and the movable toothed plate 5 can be replaced or its position adjusted as needed. To fix the movable toothed plate 5, a pressure strip 12 is slidably disposed on one side of the slot 11. Multiple positioning pins 13 are fixedly disposed on the bottom of the pressure strip 12 and on the bottom wall of the slot 11. These positioning pins 13 are used to engage with positioning holes 14 on the movable toothed plate 5, thereby fixing the movable toothed plate 5. It is worth noting that the end of the positioning pin 13 near the movable toothed plate 5 is designed in a conical shape to facilitate easier insertion of the positioning pin 13 into the positioning hole 14.

[0032] To drive the pressure bar 12 to move up and down within the slot 11, thereby fixing and releasing the movable toothed plate 5, a drive mechanism is provided. This drive mechanism includes a first rotating seat 16 fixedly mounted on the top wall of the slot 11, with a double-ended screw 9 rotatably mounted through one side of the first rotating seat 16. A movable nut 17 is threaded onto the outer wall of both ends of the double-ended screw 9, and these two movable nuts 17 are slidably mounted on the top of the slot 11. Two second rotating seats 18 corresponding to the movable nuts 17 are fixedly mounted on the top of the pressure bar 12, and each movable nut 17 is rotatably mounted on a connecting rod 19 connected to the corresponding second rotating seat 18. When the double-ended screw 9 is rotated, due to the threaded action, the two movable nuts 17 move simultaneously to the center or sides. Through the transmission action of the connecting rod 19, the pressure bar 12 can be driven to move up and down within the slot 11. To facilitate the rotation of the double-ended screw 9, a hexagonal hole 10 is provided at both ends of the double-ended screw 9, allowing it to be rotated using tools such as a wrench.

[0033] To protect the drive mechanism from external interference or damage, a protective assembly is installed. This assembly includes a slot 8 on one side of the moving jaw 3, within which a baffle 15 is installed. This baffle 15 is fixedly mounted on one side of the pressure bar 12. When the pressure bar 12 is in the lowered position, the baffle 15 shields part of the drive mechanism structure, including the double-ended screw 9, providing protection. To secure the baffle 15, multiple bolts 7 are threaded into the slot 8 on one side of the moving jaw 3. These bolts 7 pass through through holes 4 in the baffle 15, fixing the baffle 15 within the slot 8.

[0034] To ensure the stability of the pressure strip 12 during movement, three first rectangular grooves 20 are formed on one side of the moving jaw 3. A guide block 21 is slidably disposed in each of these first rectangular grooves 20, and all three guide blocks 21 are fixedly connected to the pressure strip 12. In this way, when the pressure strip 12 moves, the guide blocks 21 will slide within the first rectangular grooves 20, thus playing a guiding role.

[0035] To further position the movable toothed plate 5, a second rectangular groove 22 corresponding to the first rectangular groove 20 is formed on one side of the movable jaw 3. A sliding rod 23 is slidably disposed between each of these second rectangular grooves 22 and the corresponding first rectangular groove 20. A positioning block 24 corresponding to the second rectangular groove 22 is fixedly disposed on one side of the movable toothed plate 5, and this positioning block 24 is fitted onto the sliding rod 23. When the movable toothed plate 5 is fixed, the positioning block 24 will cooperate with the sliding rod 23 to position the movable toothed plate 5.

[0036] This application can be used in jaw crushers, or in other fields applicable to this application.

[0037] Example 2

[0038] refer to Figures 1-4 An improvement based on Embodiment 1 is provided: an easily detachable movable jaw crusher toothed plate, used in the field of jaw crushers. To facilitate the use of tools such as wrenches, a through hole 4 corresponding to the double-ended screw 9 is provided on both sides of the machine body 1. In this way, when using tools such as wrenches to rotate the double-ended screw 9, it is more convenient to pass the tools through the through hole 4 for operation.

[0039] In this application, during replacement, the bolt 7 is removed from the movable jaw 3 using a hex wrench. Then, the hex wrench is passed through the through hole 4 from the outside of the machine body 1 and inserted into the hexagonal hole 10. Rotation causes the double-ended screw 9 to rotate. During the rotation of the double-ended screw 9, the two movable nuts 17 move closer to each other. The movement of the movable nuts 17 causes the corresponding second rotating seat 18 to move upward through the connecting rod 19. The movement of the second rotating seat 18 pulls the pressure bar 12 upward, causing the positioning pin 13 at the bottom of the pressure bar 12 to disengage from the positioning hole 14 above the movable toothed plate 5. At the same time, the upward movement of the pressure bar 12 causes the guide block 21 to move upward, and also causes the baffle 15 to move upward within the slot 8. The upward movement of the guide block 21 pulls the sliding rod 23 upward, causing the sliding rod 23 to disengage from the positioning block 24. At this point, simply push the movable toothed plate 5 upward to remove it from the movable jaw 3 for replacement.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
