[0006] Preferably, there are two sets of rotating troughs and rotating blocks. The two sets of rotating troughs are opened on both sides of the crusher body, and the two sets of rotating blocks are installed on both sides of the side plate. The diameter of the rotating troughs and the diameter of the rotating blocks are the same, and the rotating blocks are rotatably connected to the surface of the rotating troughs.

[0007] Preferably, there are two sets of fixing rods and slots. The two sets of fixing rods are installed on both sides of the crusher body, and the two sets of slots are opened on both sides of the side plate. The diameter of the baffle is larger than the diameter of the through hole, and the diameter of the through hole is the same as the diameter of the fixing rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By separating the crusher body and side plates and connecting them through the installation of chute and rotating block, the side plates can be rotated to the outside of the crusher body and exposed inside the crusher body during repair and maintenance. This increases the operating space for workers and makes it easier to handle the work, preventing the reduction in work efficiency caused by the disassembly and assembly of the whole machine during operation.

[0014] 2. By setting slots and insert rods on the crusher body and side plates, the insert rods can be inserted into the slots under the action of the support springs, thereby limiting the rotation of the side plates. This prevents the need to apply force to keep the side plates from rotating when installing nuts. At the same time, the connection between the screw and the nut can fix the side plates after limiting them, preventing the vibration generated during crusher operation from causing the support spring to expand and contract, which could lead to a loose connection between the insert rods and slots. This allows the side plates to be disassembled and assembled during crusher maintenance, and ensures a firm connection at the disassembled parts when the crusher is in use.

[0023] A jaw crusher that is easy to repair and maintain includes a crusher body 1, a side plate 2 installed on one side of the crusher body 1, a movable jaw 4 installed on the other side of the crusher body 1, a motor 3 fixedly connected to the surface of the crusher body 1, a stationary jaw 5 fixedly connected to the surface of the side plate 2, a transmission assembly 6 installed on the surface of the movable jaw 4, a rotating groove 7 formed on the surface of the crusher body 1, a rotating block 8 and a mounting plate 19 fixedly connected to the surface of the side plate 2, a fixed rod 9 and a screw 20 fixedly connected to the surface of the crusher body 1, a movable plate 10 movably connected to the surface of the fixed rod 9, a baffle 11 fixedly connected to the surface of the fixed rod 9, a through hole 12 formed on the surface of the movable plate 10, and a connecting groove 13 formed on the surface of the fixed rod 9. A connecting rod 14 is fixedly connected to the surface of the through hole 12. A support spring 15 is sleeved on the surface of the fixed rod 9. A pull rod 16 and a plug rod 18 are fixedly connected to the surface of the movable plate 10. A slot 17 is opened on the surface of the side plate 2. A slot 21 is opened on the surface of the mounting plate 19. A nut 22 is installed on the surface of the screw 20. The crusher body 1, side plate 2, motor 3, moving jaw 4, stationary jaw 5 and transmission assembly 6 constitute the main body of the jaw crusher. When crushing stones, the material is first put into the crusher body 1 and placed between the moving jaw 4 and the stationary jaw 5. Then, the power is turned on and the motor 3 is started to drive the transmission assembly 6 and make the moving jaw 4 move, so that the material is crushed and then discharged.

[0024] Furthermore, there are two sets of rotating grooves 7 and rotating blocks 8. The two sets of rotating grooves 7 are opened on both sides of the crusher body 1, and the two sets of rotating blocks 8 are installed on both sides of the side plate 2. The diameter of the rotating groove 7 is the same as the diameter of the rotating block 8. The rotating block 8 is rotatably connected to the surface of the rotating groove 7. With the connection between the rotating groove 7 and the rotating block 8, the side plate 2 can rotate around the rotating block 8 as the center.

[0025] Furthermore, two sets of fixing rods 9 and slots 17 are provided. The two sets of fixing rods 9 are installed on both sides of the crusher body 1, and the two sets of slots 17 are opened on both sides of the side plate 2. The diameter of the baffle 11 is larger than the diameter of the through hole 12. The diameter of the through hole 12 is the same as the diameter of the fixing rod 9. Under the action of the baffle 11, the support spring 15 can be installed and the movable plate 10 can be limited along the direction of the fixing rod 9. The insertion rod 18 can be installed through the slots 17.

[0026] Furthermore, both ends of the connecting rod 14 are fixedly connected to the surface of the through hole 12, and the connecting rod 14 is slidably connected to the surface of the connecting groove 13. One end of the support spring 15 is abutted against the surface of the movable plate 10, and the other end of the support spring 15 is abutted against the surface of the baffle 11. The surface of the pull rod 16 is "T" shaped. The length of the connecting groove 13 is less than the length of the fixed rod 9. The connection between the connecting groove 13 and the connecting rod 14 can limit the rotation of the movable plate 10 on the fixed rod 9. The installation of the support spring 15 can apply a supporting force to the movable plate 10, and make the movable plate 10 and the insert rod 18 always tend to move towards the side plate 2. Pulling the pull rod 16 can drive the movable plate 10, the support spring 15 and the slot 17 to move together.

[0027] Furthermore, the diameter of the slot 17 is the same as the diameter of the plug rod 18. The plug rod 18 is inserted and connected to the surface of the slot 17. There are two sets of mounting plates 19 and screws 20. Under the connection of the slot 17 and the plug rod 18, the rotation limit of the side plate 2 can be realized.

[0028] Furthermore, two sets of mounting plates 19 are installed on both sides of the side plate 2, and two sets of screws 20 are installed on both sides of the crusher body 1. Each set of mounting plates 19 and screws 20 consists of two screws. The screws 20 are engaged with the surface of the slot 21. Under the action of the mounting plates 19, the rotation of the side plate 2 can be limited to prevent the side plate 2 from rotating towards the inner surface of the crusher body 1. The screws 20 are connected to the surface of the mounting plates 19 through the slots 21.

[0029] Furthermore, one end of the screw 20 is fixedly connected to the surface of the crusher body 1, and the other end of the screw 20 is threadedly connected to the inner surface of the nut 22. The nut 22 is abutted against the surface of the mounting plate 19. With the connection of the screw 20 and the nut 22, the rotation limit side plate 2 can be fixed, thereby making the connection between the crusher body 1 and the side plate 2 more firm and stable.

[0030] Working principle: When repairing and maintaining the jaw crusher, the side plate 2 needs to be opened to inspect the internal devices of the crusher body 1. First, remove the nut 22 from the surface of the screw 20 through the thread to cancel the engagement with the surface of the mounting plate 19. Then, pull the pull rods 16 on both sides of the side plate 2 to drive the movable plate 10 to slide through the through hole 12 onto the surface of the fixed rod 9, and drive the connecting rod 14 to slide onto the surface of the connecting groove 13. At this time, the support spring 15 is in a compressed state, and the insertion rod 18 slides along the surface of the slot 17 and cancels its engagement. Then, move the side plate 2 to rotate it around the rotating block 8 to the outside of the crusher body 1 and expose the interior. The rotating block 8 rotates on the surface of the rotating groove 7, and then the operation can begin.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
