Detailed Implementation

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0017] Example Reference Figure 1-7 This embodiment of the present invention provides a concrete mixing device containing end-hooked steel fibers, comprising, The mixing mechanism 100 includes a mixing tank 110, a motor 120 disposed above the mixing tank 110, a transmission rod 130 fixed to the output end of the motor 120, a rotating rod 140 fixed to the other end of the transmission rod 130 and extending into the mixing tank 110, a plurality of mixing rods 150 fixed to the surface of the rotating rod 140, and a discharge pipe 160 connected to the bottom of the mixing tank 110. The slurry disturbance mechanism 200 includes a drive component 210 disposed on the surface of the transmission rod 130, and a plurality of airflow disturbance components 220 used in conjunction with the drive component 210 to cause airflow disturbance to the slurry. The switching mechanism 300 includes a pressure plate 330 for switching the drive component 210.

[0018] The drive component 210, in conjunction with the airflow disturbance component 220, can introduce airflow into the slurry to form bubbles, thereby continuously disturbing the bottom of the slurry and effectively suppressing the settling tendency of the end-hook steel fibers. The switching mechanism 300 controls the switching of the drive component 210 through the pressure plate 330, which can flexibly adjust the airflow disturbance effect according to the mixing conditions, improve the adaptability of the device to different fiber dosages and mixing stages, and ensure the uniform mixing of concrete and end-hook steel fibers.

[0019] Specifically, the drive component 210 includes a first cam 211 and a second cam 212 sleeved on the surface of the transmission rod 130, and a linkage groove 213 formed on the surface of the first cam 211 and the second cam 212 and engaged with the transmission rod 130. The first cam 211 and the second cam 212 are slidably mounted on the surface of the transmission rod 130; the diameter of the first cam 211 is larger than the diameter of the second cam 212.

[0020] The first cam 211 and the second cam 212 are slidably mounted on the surface of the transmission rod 130 through the linkage groove 213, and can rotate synchronously with the transmission rod 130 and move axially. By utilizing the difference in diameter between the first cam 211 and the second cam 212, different amplitude driving effects can be generated on the airflow disturbance component 220 during rotation, thereby realizing graded adjustment of the airflow disturbance intensity. The first cam 211 and the second cam 212 can slide on the transmission rod 130, which facilitates the rapid switching of different disturbance intensities through the switching mechanism 300.

[0021] Furthermore, a compression spring 214 is fixed to the bottom of the transmission rod 130, and the other end of the compression spring 214 is fixedly connected to the first cam 211 and maintains an upward elastic force on the first cam 211.

[0022] The compression spring 214 provides a reliable restoring force for the first cam 211 and the second cam 212, ensuring that the first cam 211 and the second cam 212 can be stably maintained in their initial working positions when not subjected to the switching mechanism 300, thus ensuring their normal driving of the airflow disturbance component 220.

[0023] Preferably, the airflow disturbance component 220 includes a plurality of cylinders 221 disposed on the top of the mixing tank 110, a piston 222 movably installed inside the cylinder 221, a connecting rod 223 fixed to the surface of the piston 222, a cylindrical block 224 fixed to the other end of the connecting rod 223 and used to be pressed by the first cam 211 and the second cam 212, a one-way valve pipe 225 communicating with the top of the cylinder 221, an air guide pipe 226 communicating with one side of the cylinder 221, and a one-way valve 227 adapted to be installed at the other end of the air guide pipe 226; The other end of the air duct 226 extends into the interior of the mixing tank 110.

[0024] When the first cam 211 or the second cam 212 rotates and squeezes the cylindrical block 224, the piston 222 can be moved by the connecting rod 223. This, in conjunction with the one-way valve pipe 225, completes the air intake and introduces the compressed air into the slurry in the mixing tank 110 through the air guide pipe 226 to form turbulent bubbles. The one-way valve 227 at the end of the air guide pipe 226 can effectively prevent the slurry from flowing back into the air guide pipe 226, ensuring the continuity and stability of the airflow.

[0025] Furthermore, an installation ring 228 is fixedly installed inside the cylinder 221, and a return spring 229 is fixedly installed on one side of the installation ring 228. The other end of the return spring 229 is fixedly connected to the piston 222.

[0026] When the squeezing force of the first cam 211 or the second cam 212 on the cylindrical block 224 disappears, the return spring 229 can drive the piston 222 to quickly return to its original position, so that the cylinder 221 can draw in air again through the one-way valve pipe 225, ensuring the continuity of the reciprocating motion of the piston 222, thereby realizing the continuous generation and delivery of airflow.

[0027] Specifically, a collar 2210 for limiting the air guide pipe 226 is fixedly installed on the surface of the mixing tank 110. The collar 2210 is sleeved on the surface of the air guide pipe 226, and the cylinder 221 is installed on the top of the mixing tank 110 by a fixing ring.

[0028] The collar 2210 effectively limits the position of the air guide pipe 226, preventing it from shifting due to vibration during operation and ensuring the stability of the airflow path; the fixing ring is used to support and install the cylinder 221, improving its installation stability.

[0029] Furthermore, a vertical cylinder 310 is fixedly installed on the top of the mixing tank 110. A screw 320 is provided inside the vertical cylinder 310. A threaded sleeve 340 is fixedly installed on one end of the pressure plate 330. The threaded sleeve 340 is slidably installed inside the vertical cylinder 310. The threaded sleeve 340 is threaded onto the surface of the screw 320. A strip groove is opened on the surface of the vertical cylinder 310 to cooperate with the movement of the pressure plate 330. One end of the pressure plate 330 is located on the top of the second cam 212.

[0030] The rotating screw 320 can drive the threaded sleeve 340 to move along the vertical cylinder 310, thereby causing the pressure plate 330 to move up and down under the limit of the strip groove. The pressure generated by the pressure plate 330 acts on the top of the second cam 212. By adjusting the position, the working state of the first cam 211 and the second cam 212 can be switched, thereby accurately controlling the driving intensity of the driving component 210 on the airflow disturbance component 220, and meeting the airflow disturbance requirements of different stirring stages.

[0031] When in use, concrete raw materials and end-hook steel fibers are added to the mixing tank 110, the motor 120 is started, and the transmission rod 130 drives the rotating rod 140 and the mixing rod 150 to mix. At the same time, the transmission rod 130 drives the drive component 210 to work, so that the airflow disturbance component 220 introduces airflow into the slurry. As needed, the screw 320 is rotated to move the pressure plate 330, and the first cam 211 or the second cam 212 is switched to adjust the airflow intensity. After mixing is completed, the material is discharged through the discharge pipe 160.

[0032] In summary, by cooperating with the drive component 210 and the airflow disturbance component 220, airflow can be introduced into the slurry to form bubbles, which continuously disturbs the bottom of the slurry and effectively suppresses the settling tendency of the end-hook steel fibers. The switching mechanism 300 controls the switching of the drive component 210 through the pressure plate 330, which can flexibly adjust the airflow disturbance effect according to the mixing conditions, improve the adaptability of the device to different fiber dosages and mixing stages, and ensure the uniform mixing of concrete and end-hook steel fibers.
