Description

Technical Field

[0001] This utility model relates to the field of asphalt concrete mixing technology, and more specifically, to an asphalt concrete mixing device. Background Technology

[0002] In existing technologies, asphalt concrete mixing units, as important equipment in asphalt concrete production, are used to fully mix raw materials such as asphalt, aggregates, and fillers. They are widely used in infrastructure fields such as highway construction and airport construction. However, in the actual use of asphalt concrete mixing units, existing technologies for small mixing units often use a simple direct connection to connect the drive components and the mixing frame. Some use protective devices to prevent overload of the motor components in the drive components or jamming and damage to the mixing frame. However, their simple structure and fixed protection threshold make it impossible to flexibly adjust the protection threshold according to the differences in the properties of different batches of raw materials or changes in the mixing process. This results in poor protection effect and affects the adaptability and efficiency of the equipment.

[0003] Secondly, although some improved equipment has achieved flexible adjustment of the protection threshold through the cooperation of some components, its simple structure and lack of stability and reliability make it prone to unexpected changes in the adjusted structure due to factors such as vibration and impact during long-term operation, rotation of drive components, and external forces such as improper human operation. This causes the adjusted protection threshold to deviate, resulting in the failure of the protection effect. This not only affects the function of the protection device, but may also lead to adverse effects such as motor overload damage, mixing frame jamming, equipment operation interruption, and increased maintenance costs, thus restricting the working efficiency and service life of the mixing device.

By setting up a threshold adjustment system consisting of components such as a configuration sleeve, adjustment sleeve, following block, following groove, matching block, propulsion block, movable spring, and transfer frame in the asphalt concrete mixing device, when it is necessary to adjust the protection threshold according to the actual situation, the operator can flexibly adjust the protection threshold by simply rotating it.

An auxiliary groove 15 is located on the inner side of the arranging sleeve 3. The limiting sleeve 4 is located on one side of the arranging sleeve 3. A fixed connection is provided with an actuating rod 16, and an actuating plate 17 is fixedly provided on the actuating rod 16. Two actuating plates 17 are fixedly provided on the actuating rod 16. A limiting frame 18 is fixedly provided on one side of the configuration sleeve 6. A limiting rod 19 is slidably provided in the limiting frame 18. One end of the limiting rod 19 is inserted into the locking groove 13, and the other end of the limiting rod 19 is connected to a limiting plate 20. A return spring 21 is connected to one side of the limiting plate 20, and the other end of the return spring 21 is connected to the limiting frame 18. A movable spring 22 is movably provided in the auxiliary groove 15. A transfer frame 23 is slidably provided on the side wall of the auxiliary groove 15. One end of the transfer frame 23 is inserted into the transfer groove 14. A push block 24 and a matching block 25 are slidably provided in the auxiliary groove 15. The push block 24 abuts against the other end of the transfer frame 23. The two ends of the movable spring 22 are respectively connected to the push block 24 and the matching block 25. The outer wall of the adjusting sleeve 5 is movably connected to the inner wall of the configuration sleeve 6 through threads.

[0021] A mixing tank 26 is provided on the outside of the mixing frame 1, and a mounting frame 27 is provided on the outside of the mixing tank 26. The mixing tank 26 is detachably mounted on the inside of the mounting frame 27. A drive assembly 28 is detachably provided on the top of the mounting frame 27. The output end of the drive assembly 28 is connected to the top of the arrangement sleeve 3. A movable frame 29 is rotatably provided on one side below the mounting frame 27. Movable wheels 30 are rotatably provided on both sides of the movable frame 29 and both sides of the bottom of the mounting frame 27. A baffle plate 31 is slidably provided on one side of the bottom of the mixing tank 26. The baffle plate 31 blocks the discharge port opened at the bottom of the mixing tank 26.

[0022] In this embodiment, when the equipment is needed, the raw materials are first added to the mixing tank 26, and then the drive assembly 28 is turned on, causing the drive assembly 28 to drive the arrangement sleeve 3 to rotate. Then, the arrangement sleeve 3 drives the inner auxiliary groove 15 to rotate, thereby driving the push block 24 and the transfer frame 23 to rotate. This causes the transfer frame 23 to cooperate with the transfer groove 14 to drive the arrangement rod 2 to rotate, thereby causing the arrangement rod 2 to drive the mixing frame 1 to rotate. When the protection threshold is triggered, the arrangement rod 2 and the transfer groove 14 stop rotating, causing the inner wall of the transfer groove 14 to press against one end of the transfer frame 23. Due to the rounded corner joint between the inner wall of the transfer groove 14 and one end of the transfer frame 23, The transfer frame 23 is designed so that one end gradually slides out of the transfer groove 14 and moves outward. Due to the arc-shaped structure of one end of the transfer frame 23 and the special structural design of the side of the push block 24, the transfer frame 23 will press down the push block 24, causing the push block 24 to slide in the auxiliary groove 15. Then the distance between the push block 24 and the matching block 25 is shortened, causing the movable spring 22 to be squeezed. Then one end of the transfer frame 23 slides out completely from the transfer groove 14. At this time, the drive component 28 will drive the arrangement sleeve 3 to rotate idling, realizing the overload protection function. After the mixing is completed, the baffle plate 31 can be pulled out to realize the unloading operation.

[0023] Please see Figures 3-5 As a further implementation of the overall equipment: a cooperating spring 32 is movably sleeved on the outside of the actuating rod 16. One end of the cooperating spring 32 is connected to the limiting sleeve 4, and the other end of the cooperating spring 32 is in contact with the moving plate 7. Both the limit rod 19 and the inner edge of the locking groove 13 adopt a rounded corner structure design.

[0024] A linkage rod 33 is connected to one side of the linkage block 12. A linkage spring 11 is movably sleeved on the outside of the linkage rod 33. A linkage hole 34 is opened in the adapter block 10. One end of the linkage rod 33 is slidably inserted into the linkage hole 34.

[0025] The side wall of the set 3 is provided with a follower groove 35, and a follower block 36 is slidably provided in the follower groove 35. The inner wall of the set 5 is fixedly connected through the follower block 36.

[0026] Both one end of the transfer rack 23 and the inner wall of the transfer groove 14 are designed with rounded corners.

[0027] A sliding groove 37 is provided on the outer side of the arrangement sleeve 3, and a sliding block 38 is slidably arranged in the sliding groove 37. The sliding block 38 is fixedly arranged inside the limiting sleeve 4.

[0028] More specifically, when the protection threshold needs to be adjusted according to the actual situation, firstly, rotate the moving plate 7. The moving plate 7 will drive the linkage block 12 on one side to rotate forward. Then, the linkage block 12 will drive the linkage rod 33 on one side to rotate forward along the linkage hole 34. The linkage block 12 will cooperate with the adapter block 10 to squeeze the linkage spring 11. At the same time, the moving plate 7 will drive the moving hole 8 and the moving groove 9 to rotate forward. When the linkage spring 11 is squeezed to the limit, the moving hole 8 will rotate to a position concentric with the action plate 17. Then, push the limiting sleeve 4. The limiting sleeve 4 will drive the inner sliding block 38 to slide along the sliding groove 37. At the same time, the limiting sleeve 4 will drive the action rod 16 on one side and the action plate 17 to gradually slide into the moving hole 8. The limiting sleeve 4 will cooperate with the moving plate 17 to squeeze the linkage spring 11. 7. When the spring 32 is compressed to its limit, the actuating plate 17 in the middle of the actuating rod 16 passes through the moving hole 8 and moves to the other side of the moving plate 7. At this time, the moving plate 7 is released, the linkage spring 11 resets and pushes the linkage block 12 to reverse. The linkage block 12 will also drive the linkage rod 33 on one side to reverse along the linkage hole 34. At the same time, the linkage block 12 will drive the moving hole 8 and the moving groove 9 to rotate in the opposite direction through the moving plate 7, so that the actuating rod 16 enters the moving groove 9. When the outer wall of the actuating rod 16 contacts the inner wall of the moving groove 9, the actuating rod 16, together with the actuating plate 17 in the middle, limits the limiting sleeve 4 to one side of the moving plate 7, so that the limiting sleeve 4 no longer limits the outer wall of the limiting plate 20, and then rotates in the forward direction. When the mounting sleeve 6 is configured, it will cause one side of the limiting frame 18 to rotate clockwise. Then, the limiting frame 18 will cause the limiting rod 19 to rotate clockwise, causing the inner wall of the locking groove 13 to press against one end of the limiting rod 19. Due to the rounded corner design at the edge of the inner wall of the locking groove 13, one end of the limiting rod 19 will slide out of the locking groove 13, and the other end of the limiting rod 19 will cause the limiting plate 20 to slide outward, causing the limiting plate 20 to pull the return spring 21 outward. At the same time, since the outer wall of the adjusting sleeve 5 is movably connected to the inner wall of the mounting sleeve 6 through threads, and the accompanying block 36 and the accompanying groove 35 limit the rotation of the mounting sleeve 6, the adjusting sleeve 5 will cause the accompanying block 36 to slide upward along the accompanying groove 35, and then the accompanying block 36 will drive the inner wall of the locking groove 13 to rotate clockwise. The side matching block 25 slides along the auxiliary groove 15, and then the distance between the matching block 25 and the push block 24 will slowly decrease, so that the matching block 25 and the push block 24 cooperate to squeeze the movable spring 22, which increases the thrust exerted by the movable spring 22 on the push block 24, thereby increasing the thrust exerted by the push block 24 on the transfer frame 23. This means that one end of the transfer frame 23 needs to withstand a greater force to disengage from the transfer groove 14. When it is necessary for one end of the transfer frame 23 to disengage from the transfer groove 14 with only a smaller force, simply rotate the configuration sleeve 6 in the reverse direction according to the above operation. When the appropriate protection threshold is adjusted, stop rotating the configuration sleeve 6, and cause the limit frame 18 to drive the limit rod 19 and other components to rotate to the position corresponding to the locking groove 13.Then, the return spring 21 resets and pulls the limit plate 20, causing the limit plate 20 to slide the limit rod 19 inward. One end of the limit rod 19 then inserts into the corresponding locking groove 13. The moving plate 7 rotates forward again, causing it to synchronously rotate the linkage block 12 on one side. The linkage block 12 then rotates the linkage rod 33 along the linkage hole 34, and it again engages with the adapter block 10 to press the linkage spring 11. Simultaneously, the moving plate 7 rotates the moving hole 8 and the moving groove 9. When the moving hole 8 rotates to a position concentric with the action plate 17, the cooperating spring 32 pushes the limit sleeve 4, causing the inner sliding block 38 to slide back along the sliding groove 37. The limit sleeve 4 also causes the action rod 16 on one side and the two action plates 17 to slide back. When the cooperating spring 32 is fully reset, the action plate 17 at the top of the action rod 16 moves back to its original position on the moving plate 7. At this point, the moving plate is released again. 7. Then, the linkage spring 11 resets and pushes the linkage block 12 to rotate in the opposite direction. The linkage block 12 then drives the linkage rod 33 on one side to rotate in the opposite direction along the linkage hole 34. Simultaneously, the linkage block 12, through the moving plate 7, drives the moving hole 8 and the moving groove 9 to rotate in the opposite direction, thus causing the moving plate 7 to rotate the moving hole 8 and the moving groove 9 to a position not corresponding to the action rod 16 and the action plate 17. Then, the action rod 16, in conjunction with the top action plate 17, limits and supports the limiting sleeve 4 to one side of the moving plate 7. Combined with the sliding block 38 and the sliding groove 37, the limiting sleeve 4 cannot move. The inner wall of the limiting sleeve 4 then limits the outer wall of the limiting plate 20, preventing the limiting plate 20 and the limiting rod 19 from sliding outwards. Finally, the limiting rod 19 and the corresponding locking groove 13 lock the limiting frame 18 and the configuration sleeve 6, preventing the configuration sleeve 6 from moving or rotating, thus preventing the adjusted components from shifting and ensuring the protective effect.

[0029] In summary, during the use or operation of the overall equipment: When the equipment needs to be used, first add the raw materials into the mixing tank 26, then turn on the drive assembly 28, causing the drive assembly 28 to drive the arrangement sleeve 3 to rotate. Then, the arrangement sleeve 3 drives the inner auxiliary groove 15 to rotate, thereby driving the propulsion block 24 and the transfer frame 23 to rotate. This causes the transfer frame 23 to cooperate with the transfer groove 14 to drive the arrangement rod 2 to rotate, thereby causing the arrangement rod 2 to drive the mixing frame 1 to rotate. When the protection threshold is triggered, the arrangement rod 2 and the transfer groove 14 stop rotating, causing the inner wall of the transfer groove 14 to press against one end of the transfer frame 23. Due to the pressure between the inner wall of the transfer groove 14 and one end of the transfer frame 23... The rounded corner structure design allows one end of the transfer frame 23 to gradually slide out of the transfer groove 14, and the transfer frame 23 will move outward. Due to the arc structure of one end of the transfer frame 23 and the special structural design of one side of the push block 24, the one end of the transfer frame 23 will press down the push block 24, causing the push block 24 to slide in the auxiliary groove 15. Then the distance between the push block 24 and the matching block 25 will shorten, causing the movable spring 22 to be squeezed. Then one end of the transfer frame 23 will slide completely out of the transfer groove 14. At this time, the drive component 28 will drive the arrangement sleeve 3 to rotate idling, realizing the overload protection function. After the mixing is completed, the baffle plate 31 can be pulled out to realize the unloading operation.

[0030] When the protection threshold needs to be adjusted according to the actual situation, first rotate the moving plate 7. The moving plate 7 will drive the linkage block 12 on one side to rotate forward. Then, the linkage block 12 will drive the linkage rod 33 on one side to rotate forward along the linkage hole 34. The linkage block 12 will cooperate with the adapter block 10 to squeeze the linkage spring 11. At the same time, the moving plate 7 will drive the moving hole 8 and the moving groove 9 to rotate forward. When the linkage spring 11 is squeezed to the limit, the moving hole 8 will rotate to the position concentric with the action plate 17. Then push the limiting sleeve 4. The limiting sleeve 4 will drive the inner sliding block 38 to slide along the sliding groove 37. At the same time, the limiting sleeve 4 will drive the action rod 16 on one side and the action plate 17 to gradually slide into the moving hole 8. The limiting sleeve 4 will cooperate with the moving plate 7 to squeeze the linkage spring 31. 2. When the cooperating spring 32 is compressed to its limit, the actuating plate 17 set in the middle section of the actuating rod 16 just passes through the moving hole 8 and moves to the other side of the moving plate 7. At this time, the moving plate 7 is released, the linkage spring 11 resets and pushes the linkage block 12 to reverse, and the linkage block 12 will drive one side of the linkage rod 33 to reverse along the linkage hole 34. At the same time, the linkage block 12 will drive the moving hole 8 and the moving groove 9 to rotate in the opposite direction through the moving plate 7, so that the actuating rod 16 enters the moving groove 9. When the outer wall of the actuating rod 16 contacts one end of the inner wall of the moving groove 9, the actuating rod 16, in conjunction with the actuating plate 17 set in the middle section, limits the limiting sleeve 4 to one side of the moving plate 7, so that the limiting sleeve 4 no longer limits the outer wall of the limiting plate 20. Then, the configuration sleeve 6 is rotated in the forward direction, and the configuration sleeve 6 will bring When the limiting bracket 18 rotates forward, it drives the limiting rod 19 to rotate forward, causing the inner wall of the locking groove 13 to press against one end of the limiting rod 19. Due to the rounded corner design at the edge of the inner wall of the locking groove 13, one end of the limiting rod 19 slides out of the locking groove 13, and the other end of the limiting rod 19 drives the limiting plate 20 to slide outward, causing the limiting plate 20 to pull the return spring 21 outward. At the same time, because the outer wall of the adjusting sleeve 5 is movably connected to the inner wall of the configuration sleeve 6 through threads, and the accompanying block 36 and the accompanying groove 35 limit the rotation of the configuration sleeve 6, the adjusting sleeve 5 drives the accompanying block 36 to slide upward along the accompanying groove 35. Then, the accompanying block 36 drives the inner matching block 25 to slide along the auxiliary groove 15. The movement causes the distance between the matching block 25 and the push block 24 to slowly decrease, allowing them to work together to compress the movable spring 22. This increases the thrust exerted by the movable spring 22 on the push block 24, which in turn increases the thrust exerted by the push block 24 on the transfer frame 23. Consequently, one end of the transfer frame 23 needs to withstand a greater force to detach from the transfer groove 14. When it is necessary for one end of the transfer frame 23 to detach from the transfer groove 14 with only a smaller force, simply reverse the rotation of the configuration sleeve 6 according to the above operation. When the appropriate protection threshold is reached, stop rotating the configuration sleeve 6 and allow the limit frame 18 to rotate the limit rod 19 and other components to the position corresponding to the locking groove 13. Then, the return spring 21 resets and pulls the limit plate 20.The limiting plate 20 causes the limiting rod 19 to slide inward, and then one end of the limiting rod 19 is inserted into the corresponding locking groove 13. Then the moving plate 7 is rotated forward again, causing the moving plate 7 to drive the linkage block 12 on one side to rotate synchronously. Then the linkage block 12 will drive the linkage rod 33 on one side to rotate forward along the linkage hole 34. The linkage block 12 will cooperate with the adapter block 10 again to squeeze the linkage spring 11. At the same time, the moving plate 7 will drive the moving hole 8 and the moving groove 9 to rotate forward again. When the moving hole 8 rotates to the position concentric with the action plate 17, the cooperating spring 32 pushes the limiting sleeve 4 to drive the inner sliding block 38 to slide and reset along the sliding groove 37. The limiting sleeve 4 will drive the action rod 16 on one side and the two action plates 17 to slide and reset. When the cooperating spring 32 is fully reset, the action plate 17 set at the top of the action rod 16 just moves back to the original side of the moving plate 7. At this time, the moving plate 7 is released again, and the linkage spring 11... 1. The reset pushes the linkage block 12 to rotate in the opposite direction to reset. Then, the linkage block 12 drives the linkage rod 33 on one side to rotate in the opposite direction along the linkage hole 34 to reset. At the same time, the linkage block 12 drives the moving hole 8 and the moving groove 9 to rotate in the opposite direction again through the moving plate 7 to reset. This causes the moving plate 7 to drive the moving hole 8 and the moving groove 9 to rotate in the opposite direction to reset to a position that does not correspond to the action rod 16 and the action plate 17. Then, the action rod 16, together with the top action plate 17, limits and supports the limiting sleeve 4 to one side of the moving plate 7. With the help of the sliding block 38 and the sliding groove 37, the limiting sleeve 4 is limited, so that the limiting sleeve 4 cannot move. Then, the inner wall of the limiting sleeve 4 limits the outer wall of the limiting plate 20, so that the limiting plate 20 and the limiting rod 19 cannot slide outward. Then, the limiting rod 19 and the corresponding locking groove 13 cooperate to lock the limiting frame 18 and the configuration sleeve 6, preventing the configuration sleeve 6 from moving or rotating, thereby preventing the adjusted parts from shifting and ensuring the protective effect.
