[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 - Figure 6 , a feeding device for a concrete production expansion agent, including a processing device 1. A fixing ring 2 is fixedly assembled on the outer wall of the processing device 1. A controller 3 and a first motor 4 are respectively fixedly assembled on the outer wall of the fixing ring 2. One end of a rotating rod 12 is fixedly assembled on the power output shaft of the first motor 4, and a collision rod 13 is fixedly assembled at the other end of the rotating rod 12. A limiting groove 14 is opened on the inner wall of the processing device 1. A connecting block 26 is slidably connected to the inner wall of the limiting groove 14. A filter plate 11 is fixedly assembled on the outer wall of the connecting block 26. A second spring 28 and a telescopic plate 29 are fixedly assembled on the inner wall of the limiting groove 14. A limiting rod 27 is fixedly assembled on the top of the connecting block 26. A feeding pipe 5 and a second motor 6 are respectively fixedly assembled on the top of the processing device 1. A rotating shaft 9 is fixedly assembled on the power output shaft of the second motor 6, and stirring blades 10 are fixedly assembled on the outer wall of the rotating shaft 9.

[0023] In the above structure, by the controller 3 sending a signal, the power output shaft of the first motor 4 rotates after receiving the signal. The first motor 4 drives the rotating rod 12 and the collision rod 13 to rotate. During the rotation of the collision rod 13, pressure is applied to the filter plate 11 to cause it to rise. Subsequently, the filter plate 11 is forced to push the connecting block 26 to slide on the inner wall of the limiting groove 14. During this sliding process, the connecting block 26 further pushes the limiting rod 27 to apply pressure to the second spring 28, resulting in the release of the elastic potential energy stored in the second spring 28. The released elastic potential energy then drives the second spring 28 to drive the connecting block 26 and the filter plate 11 to vibrate rapidly on the inner wall of the limiting groove 14. The vibration process enables the filter plate 11 to effectively screen the concrete expansion agent. Through the action of the telescopic plate 29, it is ensured that the filter plate 11 can be telescopically adjusted during the movement, thereby effectively preventing the concrete expansion agent from entering the inner wall of the limiting groove 14 and causing blockage of the connecting block 26.

[0024] In a preferred embodiment: A guiding block 15 and a limiting plate 16 are fixedly assembled on the inner wall of the processing device 1. A third motor 17 is fixedly assembled on the outer wall of the limiting plate 16. A first rotating column 18 is fixedly assembled on the power output shaft of the third motor 17. A baffle plate 19 is fixedly assembled on the outer wall of the first rotating column 18. A discharge pipe 8 is fixedly assembled at the bottom of the processing device 1. A fourth motor 20 and an electronic sensor 21 are respectively fixedly assembled on the outer wall of the discharge pipe 8. A second rotating column 22 is fixedly assembled on the power output shaft of the fourth motor 20. A rotating plate 23 is fixedly assembled on the outer wall of the second rotating column 22. One end of a first weighing spring 24 is fixedly assembled on the top of the rotating plate 23, and the other end of the first weighing spring 24 is fixedly assembled with a weighing device 25. A conveying device 7 is arranged at the bottom of the processing device 1.

[0025] In the above structure, the concrete expansion agent is guided by the guiding block 15 so that it accurately falls from the notch of the guiding block 15 onto the top of the weighing device 25 for weighing. During the weighing process, the weighing device 25 and the first weighing spring 24 work together. Once the weighing device 25 senses that the specified weight is reached, it will immediately send a signal to the electronic sensor 21. After receiving the signal, the electronic sensor 21 will then send instructions to the fourth motor 20 and the third motor 17 respectively. After receiving the signal, the power output shaft of the third motor 17 will drive the first rotating column 18 to rotate, thereby driving the baffle plate 19 to rotate synchronously. It is realized through two sets of mechanical structures composed of the limiting plate 16, the third motor 17, the first rotating column 18 and the baffle plate 19 to ensure that the notch of the guiding block 15 is closed in time to prevent materials from accidentally falling into the inner wall of the discharge pipe 8 during transportation. After receiving the signal, the power output shaft of the fourth motor 20 will drive the second rotating column 22 to rotate, thereby driving the rotating plate 23, the first weighing spring 24 and the weighing device 25 to rotate as a whole, so that the weighed concrete expansion agent can smoothly flow from the notch of the discharge pipe 8 into the top of the conveying device 7 to complete the feeding.

[0026] In a preferred embodiment: A filter plate 11 is fixedly assembled at the telescopic end of the telescopic plate 29, and the collision rod 13 is made of rubber.

[0027] In the above structure, when the filter plate 11 moves, it will drive the telescopic plate 29 to expand and contract, avoiding the expansion agent flowing into the slot of the limiting groove 14 and causing blockage during the filtration of the expansion agent. Since the collision rod 13 is made of rubber, the collision rod 13 will not cause damage to the collision rod 13 and the filter plate 11 when touching the filter plate 11.

[0028] In a preferred embodiment: The first motor 4, the second motor 6, the conveying device 7, the third motor 17, the fourth motor 20, the electronic sensor 21, and the weighing device 25 are all electrically connected to the controller 3, and both the fourth motor 20 and the third motor 17 are electrically connected to the electronic sensor 21.

[0029] In the above structure, a signal is sent by the controller 3, causing the device to operate after receiving the signal. The electronic sensor 21 directly sends signals to the fourth motor 20 and the third motor 17.

[0030] In a preferred embodiment: The guiding block 15 is located in the middle of the filter plate 11 and the limiting plate 16, and the baffle plate 19 fits with the notch of the guiding block 15.

[0031] In the above structure, the screened expansive agent is guided through the top of the guiding block 15, and then the notch of the guiding block 15 is opened and closed by the limiting plate 16. By making the baffle plate 19 fit with the notch of the guiding block 15, the expansive agent at the top of the guiding block 15 will not flow out when the baffle plate 19 fits with the notch of the guiding block 15.

[0032] In a preferred embodiment: The number of the connecting blocks 26, the limiting rods 27, the second springs 28, and the telescopic plates 29 is four each, and the four connecting blocks 26, the limiting rods 27, the second springs 28, and the telescopic plates 29 are respectively located on the inner wall of the processing device 1, and the four connecting blocks 26, the limiting rods 27, the second springs 28, and the telescopic plates 29 are annularly distributed on the inner wall of the processing device 1.

[0033] In the above structure, through the four connecting blocks 26, the limiting rods 27, the second springs 28, and the telescopic plates 29, the vibration effect of the filter plate 11 is better, enabling the filter plate 11 to efficiently screen the concrete expansive agent.

[0034] Working principle: By sending a signal through the controller 3, after the driving motor 4 receives the signal, its power output shaft rotates immediately, and then drives the rotating rod 12 and the collision rod 13 to rotate synchronously. During the rotation process, the collision rod 13 exerts extrusion and lifting actions on the filter plate 11. This extrusion force causes the filter plate 11 to drive the connecting block 26 to slide on the inner wall of the limiting groove 14. Furthermore, when the connecting block 26 moves, it drives the limiting rod 27 to exert pressure on the second spring 28. After the second spring 28 is subjected to pressure, its elastic potential energy is released, and it drives the connecting block 26 and the filter plate 11 to vibrate rapidly on the inner wall of the limiting groove 14, thereby realizing the effective screening of the concrete expansion agent. At the same time, the design of the telescopic plate 29 ensures that the filter plate 11 can expand and contract during the movement process, effectively preventing the concrete expansion agent from entering the inner wall of the limiting groove 14 and avoiding the possible blockage phenomenon of the connecting block 26. The guiding block 15 plays a guiding role, enabling the concrete expansion agent to smoothly fall from the notch of the guiding block 15 onto the top of the weighing device 25 for weighing. The weighing device 25 and the first weighing spring 24 work together to accurately weigh the concrete expansion agent. When the weighing device 25 senses that the specified weight is reached, it sends a signal to the electronic sensor 21. After receiving the signal, the electronic sensor 21 sends instructions to the fourth motor 20 and the third motor 17 respectively. After receiving the signal, the power output shaft of the third motor 17 drives the first rotating column 18 to rotate, and then drives the blocking plate 19 to rotate. Through two sets of mechanisms composed of the limiting plate 16, the third motor 17, the first rotating column 18, and the blocking plate 19, the function of closing the notch of the guiding block 15 is realized, ensuring that no materials will fall into the inner wall of the discharge pipe 8 during the conveying process. After receiving the signal, the power output shaft of the fourth motor 20 drives the second rotating column 22 to rotate, and then drives the rotating plate 23, the first weighing spring 24, and the weighing device 25 to rotate together. This action causes the weighed concrete expansion agent to smoothly flow from the notch of the discharge pipe 8 onto the top of the conveying device 7, completing the feeding process.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
