[0016] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following is combined with the drawings and examples, and the utility model is further described in detail. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0017] The modularized mine wet-spraying concrete floor primary mixing device comprises:

[0018] The tank body 10;

[0019] The stirring assembly comprises a rotating shaft 21 rotatably inserted into the tank body 10, a plurality of stirring parts 23 arranged on the rotating shaft 21, and a plurality of propeller blades 22 fixedly arranged on the rotating shaft 21, wherein the plurality of propeller blades 22 and the plurality of stirring parts 23 are alternately distributed, the stirring part 23 comprises a fixed cylinder 232 coaxially sleeved on the surface of the rotating shaft 21 and a plurality of stirring rods 234 rotatably inserted into the circumferential surface of the fixed cylinder 232, one end of the stirring rod 234 located inside the fixed cylinder 232 is fixedly connected with a conical gear two 233, and the surface of the rotating shaft 21 and located inside the fixed cylinder 232 are fixedly sleeved with a conical gear one 231 engaged with the conical gear two 233.

[0020] Specifically, the external force drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the propeller blade 22 and the stirring piece 23 to move together. During the rotation of the propeller blade 22, an axial conveying force is generated on the material in the tank body 10, and the material flows upward along the direction of the rotating shaft 21 in the tank body 10, thereby avoiding local accumulation of the material in the tank body and preliminarily realizing macroscopic mixing of the material in the tank body 10. The stirring piece 23 rotates together with the rotating shaft 21, and the plurality of stirring rods 234 are rotatably inserted into the circumferential surface of the fixed cylinder 232. Therefore, when the fixed cylinder 232 rotates, the stirring rods 234 are driven to move in a circular motion around the rotating shaft 21. When the rotating shaft 21 rotates, the conical gear one 231 rotates, and under the action of gear transmission, the conical gear two 233 drives the stirring rods 234 to rotate around their own axes. The stirring rods 234 move in a circular motion around the rotating shaft 21 and rotate around their own axes. This compound motion enables the stirring rods 234 to stir the material in multiple directions and at multiple angles, which can more finely disperse and mix the material, promote sufficient contact between the materials, and thus improve the uniformity of the stirring. The axial material flow generated by the propeller blade 22 can continuously transport the material to the area where the stirring piece 23 is located for stirring, which can ensure the overall circulation of the material and achieve the purpose of fine mixing through local strong shearing force. Through such repeated processes, efficient and uniform mixing of the material in the tank body 10 is realized, which can ensure that the initially mixed concrete has good workability and uniformity and meets the subsequent spraying process requirements.

[0021] In one embodiment, a motor 20 is further included, and the top of the rotating shaft 21 is fixedly connected with the output shaft of the motor 20. The motor 20 serves as a power source, and the rotation of the output shaft of the motor 20 directly drives the rotating shaft 21 to rotate in the tank body 10. The rotation of the rotating shaft 21 is the basis of the entire stirring process, and it provides power for the subsequent movement of the propeller blade 22 and the stirring piece 23.

[0022] In one embodiment, the stirring rod 234 is provided with a movable rod 235 at the end away from the rotating shaft 21, and the end of the movable rod 235 away from the stirring rod 234 is fixedly connected with a scraper 236. The rotation of the movable rod 235 and the scraper 236 can clean the residual material on the inner wall of the tank body 10. Through continuous scraping action, the scraper 236 can bring the concrete material adhering to the inner wall of the tank body back into the stirring area, thereby avoiding material loss, ensuring that all materials can be fully mixed, reducing waste and improving mixing uniformity, and also reducing the difficulty of subsequent cleaning work.

[0023] In one embodiment, the movable rod 235 is movably connected with the stirring rod 234, and a section of the movable rod 235 inside the stirring rod 234 is wound with a spring 237. Due to the movable connection between the movable rod 235 and the stirring rod 234 and the support of the spring 237 inside, the scraper 236 can automatically adjust the angle and position when contacting the inner wall of the tank 10, ensuring close contact with the inner wall surface. When the scraper 236 contacts the inner wall of the tank 10, the spring 237 is compressed, providing a buffer effect to prevent damage to the equipment caused by hard collision. At the same time, the resilience of the spring 237 helps the scraper 236 maintain pressure on the inner wall, ensuring effective removal of adhering objects. The presence of the spring 237 enables the scraper 236 to flexibly adapt to various curvature changes of the inner wall of the tank 10, even in the face of an irregular inner wall, and maintain good contact.

[0024] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them.
