[0002] A crusher is a machine that crushes large solid raw materials to the required size. A crusher consists of coarse crushing, fine crushing, and pneumatic conveying devices. It achieves the purpose of crushing by high-speed impact and uses wind power to grind the raw materials into powder in one step. After the crusher crushes the raw materials, it is necessary to disperse and mix the agglomerated and accumulated raw materials.

[0003] In existing technologies, raw materials are mixed using a stirring rod. However, some raw materials clump together at the bottom of the device during mixing. The clumps at the bottom cannot be dispersed quickly and cannot be fully mixed with the raw materials at the top, resulting in insufficient mixing and thus low mixing efficiency, which affects the quality of the raw materials. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that some raw materials clump together at the bottom of the device during mixing, and the clumps at the bottom cannot be dispersed quickly and cannot be fully mixed with the raw materials at the top, resulting in low mixing efficiency. Therefore, this invention proposes a raw material turning and mixing mechanism for a crusher.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a raw material turning mechanism for a crusher, comprising a turning cylinder, a fixed box fixedly connected to one end of the turning cylinder, a rotating roller rotatably connected inside the fixed box, a guide groove formed on the outer surface of the rotating roller, a movable block slidably connected inside the guide groove, one end of the movable block slidably connected to one side of the fixed box, a rotating rod fixedly connected to one end of the movable block, one end of the rotating rod passing through one end of the turning cylinder, a stirring rod fixedly connected to the outside of the rotating rod, an external gear ring fixedly connected to the outside of the turning cylinder, a first gear meshing on one side of the external gear ring, a connecting rod fixedly connected to the middle of the first gear, a belt assembly installed on the outside of the connecting rod, a first drive motor connected to the connecting rod via the belt assembly, one end of the first drive motor fixedly connected to a support frame, and the support frame rotatably connected to the connecting rod.

[0006] Preferably, one end of the rotating roller is fixedly connected to a fixing rod, one end of the fixing rod passes through one end of the fixing box, and one end of the fixing rod is fixedly connected to a third gear, with a second gear meshing on one side of the third gear.

[0007] Preferably, a second drive motor is fixedly connected to one end of the fixed box, and the output end of the second drive motor passes through one end of the fixed box and is fixedly connected to the middle of the second gear.

[0008] Preferably, the outside of the tilting cylinder is rotatably connected to a support collar, and the support collar is fixedly connected to the support frame.

[0009] Preferably, a positioning block is fixedly connected to the outer surface of the tilting cylinder, a rotating block is rotatably connected to the outside of the positioning block, and a cover plate is fixedly connected to one end of the rotating block.

[0010] Preferably, the cover plate is rotatably connected to a feed inlet at its center.

[0011] Preferably, a connecting block is fixedly connected to one end of the cover plate, an electric push rod is rotatably connected to one end of the connecting block, a rotating frame is rotatably connected to the outside of the electric push rod, and one end of the rotating frame is fixedly connected to the outer surface of the tilting cylinder.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the first drive motor drives the connecting rod and the first gear to rotate, the outer gear ring and the tilting cylinder to rotate, and the raw material to continuously tumble. The second drive motor drives the second gear to rotate, which in turn drives the third gear, the fixed rod and the rotating roller to rotate. One end of the moving block slides inside the guide groove, which can drive the moving block to make reciprocating linear motion, so that the rotating rod and the stirring rod move, and simultaneously stir the raw material tumbling inside the tilting cylinder, which can improve the stirring effect of the raw material and prevent the raw material from accumulating and clumping, thus affecting the processing quality of the raw material.

[0014] 2. In this utility model, after the mixing inside the tilting drum is completed, the connecting block is moved by the operation of the electric push rod. The electric push rod rotates on the rotating frame, and the connection between the electric push rod and the connecting block rotates. The rotating block rotates outside the positioning block, thereby opening the cover plate that is closed to one end of the tilting drum. During this process, the feed port can shrink as the cover plate rotates. The opening of the cover plate sends out the raw material that has been mixed inside the tilting drum, which is convenient for feeding the mixed raw material. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1-4 As shown, this utility model provides a raw material turning mechanism for a crusher, including a turning cylinder 18. A fixed box 5 is fixedly connected to one end of the turning cylinder 18. A rotating roller 23 is rotatably connected inside the fixed box 5. A guide groove 24 is formed on the outer surface of the rotating roller 23. A moving block 9 is slidably connected inside the guide groove 24. One end of the moving block 9 is slidably connected to one side of the fixed box 5. A rotating rod 20 is fixedly connected to one end of the moving block 9. One end of the rotating rod 20 passes through one end of the turning cylinder 18. A stirring rod 21 is fixedly connected to the outside of the rotating rod 20. An external gear ring 10 is fixedly connected to the outside of the turning cylinder 18. A first gear 4 meshes with one side of the external gear ring 10. A connecting rod 22 is fixedly connected to the middle of the first gear 4. A belt assembly 3 is installed on the outside of the 2. The connecting rod 22 is connected to the first drive motor 2 through the belt assembly 3. One end of the first drive motor 2 is fixedly connected to the support frame 1. The support frame 1 is rotatably connected to the connecting rod 22. One end of the rotating roller 23 is fixedly connected to the fixing rod 25. One end of the fixing rod 25 passes through one end of the fixing box 5. One end of the fixing rod 25 is fixedly connected to the third gear 8. One side of the third gear 8 is meshed with the second gear 7. One end of the fixing box 5 is fixedly connected to the second drive motor 6. The output end of the second drive motor 6 passes through one end of the fixing box 5 and is fixedly connected to the middle of the second gear 7. The outside of the tilting cylinder 18 is rotatably connected to the support collar 17. The support collar 17 is fixedly connected to the support frame 1.

[0023] With the belt assembly 3, which consists of two pulleys and a transmission belt, when the first drive motor 2 is working, it drives the connecting rod 22 and the first gear 4 to rotate. The first gear 4 meshes with the outer gear ring 10, thereby driving the outer gear ring 10 and the tilting drum 18 to rotate. The raw material inside the tilting drum 18 is continuously tilted. When the second drive motor 6 is working, it drives the second gear 7 to rotate. The second gear 7 meshes with the third gear 8, thereby driving the third gear 8, the fixed rod 25, and the rotating roller 23 to rotate in sequence. A guide groove 24 is provided on the outer surface of the rotating roller 23. The guide groove 24 is a closed ellipse surrounding the outer surface of the rotating roller 23. The circular groove, and one end of the moving block 9 slides inside the guide groove 24. When the moving block 9 moves to different positions in the guide groove 24 with the rotation of the rotating roller 23, the moving block 9 is slidably connected to the fixed box 5. The moving block 9 moves in a straight line and moves to different positions in the guide groove 24. As the guide groove 24 rotates continuously with the rotating roller 23, it can drive the moving block 9 to make a reciprocating straight line motion, so that the rotating rod 20 and the stirring rod 21 make a reciprocating straight line motion accordingly, and simultaneously stir the raw materials tumbling inside the turning drum 18, which can improve the stirring effect of the raw materials and prevent the raw materials from accumulating and clumping, affecting the processing quality of the raw materials.

[0024] Example 2: Figure 1 and Figure 2 As shown, a positioning block 15 is fixedly connected to the outer surface of the tilting cylinder 18, and a rotating block 13 is rotatably connected to the outside of the positioning block 15. A cover plate 19 is fixedly connected to one end of the rotating block 13. A feed inlet 16 is rotatably connected to the middle of the cover plate 19. A connecting block 14 is fixedly connected to one end of the cover plate 19, and an electric push rod 11 is rotatably connected to one end of the connecting block 14. A rotating frame 12 is rotatably connected to the outside of the electric push rod 11, and one end of the rotating frame 12 is fixedly connected to the outer surface of the tilting cylinder 18.

[0025] During the rotation of the tilting drum 18, one end of the feed inlet 16 is rotatably connected to the tilting drum 18, and the other end of the feed inlet 16 is fixedly connected to the discharge port of the crusher, providing lateral support for the feed inlet 16. This prevents the feed inlet 16 from rotating during the rotation of the tilting drum 18. After the mixing inside the tilting drum 18 is completed, the electric push rod 11 drives the connecting block 14 to move. The electric push rod 11 rotates on the rotating frame 12, and the connection between the electric push rod 11 and the connecting block 14 rotates. The rotating block 13 rotates outside the positioning block 15, thereby opening the cover plate 19 that is closed at one end of the tilting drum 18. During this process, the feed inlet 16 can retract with the rotation of the cover plate 19. The opening of the cover plate 19 sends out the raw material that has been mixed inside the tilting drum 18, making it convenient to discharge the mixed raw material.

[0026] The device is used and operates as follows: One end of the feed inlet 16 is connected to the discharge port of the crusher, which can send the raw materials inside the crusher to the inside of the tilting drum 18. When the first drive motor 2 is working, it drives the connecting rod 22 and the first gear 4 to rotate, the outer gear ring 10 and the tilting drum 18 to rotate, causing the raw materials to continuously tumble. The second drive motor 6 drives the second gear 7 to rotate, which in turn drives the third gear 8, the fixed rod 25 and the rotating roller 23 to rotate. One end of the moving block 9 slides inside the guide groove 24. The moving block 9 moves in a straight line. As the guide groove 24 rotates with the rotating roller 23, the moving block 9, the rotating rod 20 and the stirring rod 21 move in a reciprocating straight line, which simultaneously stirs the raw materials tumbling inside the tilting drum 18. After the raw materials are stirred, the electric push rod 11 drives the connecting block 14 to move, and the rotating block 13 rotates outside the positioning block 15, opening the cover plate 19 that is closed to one end of the tilting drum 18, and sending the raw materials out of the tilting drum 18.
