Description

Technical Field

[0001] The utility model relates to the technical field of building material mixing, and more specifically, to a building material mixing device. Background Art

[0002] In the prior art, the operation and maintenance of building material mixing devices face some specific technical challenges, mainly involving the adhesion problem of materials in the mixing tank, the complexity of the connection between the mixing rod and the motor, and the risk of breaking the mixing rod under high viscosity or curing conditions.

[0003] First, during the mixing process, building materials tend to adhere to the inner wall of the mixing tank. This adhesion phenomenon not only affects the mixing effect and reduces the uniformity of the mixture, but may also cause some materials to fail to be fully mixed, affecting the quality of the final product. In addition, cleaning the materials adhered to the tank wall usually requires additional labor and time, increasing production costs and downtime.

[0004] Secondly, in the prior art, the connection between the top of the mixing rod and the output end of the motor is usually designed to be a fixed or rigid connection. Although this design is simple and stable, it is complicated and cumbersome when maintaining or replacing the mixing rod. Usually, special tools are required to complete the connection and disconnection operations, which not only increases the operating difficulty of the staff, but also affects the efficiency of maintenance and replacement. Rapid maintenance and replacement of the mixing rod is crucial to improving production efficiency and reducing downtime, especially in high-load and continuous production environments.

[0005] Furthermore, when the raw materials in the mixing tank are too viscous or begin to solidify, the traditional rigid connection may cause the mixing rod to be subjected to excessive mechanical stress while the motor continues to run. If the motor is not turned off in time, this overload situation can easily cause the mixing rod to break or be damaged, which not only affects production continuity, but may also lead to expensive equipment maintenance costs and safety risks.

A quick-change device is connected to the connecting sleeve 9, a plug-in rod 10 is provided on the inner side of the connecting sleeve 9, and a protective mechanism is connected to the top of the mixing rod 6, the protective mechanism includes a limit plate 11, a limit groove 12, a push spring 13, a connecting rod 14, a rotating plate 15 and a rotating groove 16. One end of the limit plate 11 is connected to the push spring 13, and the push spring 13 is movably installed in the connecting sleeve 9. The limit groove 12 is opened on the side wall of the connecting rod 14, and the connecting rod 14 is connected to the top of the mixing rod 6. The rotating plate 15 is fixedly connected to the top of the connecting rod 14, and the rotating plate 15 is movably installed in the rotating groove 16.

[0033] A feeding pipe 17 is provided on the side wall of the mixing tank 2 , and a discharging pipe 18 is provided at the bottom end of the mixing tank 2 .

[0034] A mixing disk 19 is provided inside the mixing tank 2 , and the mixing disk 19 is installed on the side wall of the mixing rod 6 . A connecting tube 20 is provided outside the mixing disk 19 .

[0035] In this embodiment, when the device needs to be used for mixing, the raw materials are added into the mixing tank 2 through the feed pipe 17, and then the motor 4 installed on the bracket 5 is turned on. The motor 4 drives the mixing rod 6 to rotate, thereby driving the mixing disk 19 to rotate, thereby realizing the mixing process.

[0040] A spring 29 is provided on one side of the matching block 23 , and the other end of the spring 29 is connected to the connecting sleeve 9 .

[0041] More specifically, when the mixing rod 6 needs to be replaced or maintained as a whole, the tank cover 3 is removed from the top of the mixing tank 2, and then the drawstrings 28 arranged on both sides are pulled, and the drawstrings 28 will drive the matching block 23 to rotate on the outside of the connecting sleeve 9, and at the same time, the matching block 23 will squeeze the spring 29 arranged on one side, and then the matching block 23 will drive the matching groove 21 to move. Due to the special structural design of the matching groove 21 and the matching plate 22, when the matching block 23 moves, the matching block 23 will drive the matching plate 22 to move outward through the matching groove 21, and then the matching plate 22 will drive the plug-in The rack 24 moves outward, and the plug-in rack 24 will gradually disengage from the plug-in slot 25. When the pull strap 28 cannot be pulled, the spring 29 is compressed to the limit, and one end of the plug-in rack 24 is completely disengaged from the plug-in slot 25. Then, the mixing rod 6 can be pulled downward to pull the plug-in rod 10 and the connecting rod 14 out of the connecting sleeve 9, thereby realizing the removal of the mixing rod 6. After the replacement or maintenance of the mixing rod 6 is completed, the plug-in rod 10 and the connecting rod 14 are re-engaged in the connecting sleeve 9 with reference to the above process. The setting of the guide rail 26 and the guide groove 27 mainly plays a guiding and limiting role.

[0042] In summary, when the overall equipment is in use or running: when the equipment needs to be used for mixing, the raw materials are added to the mixing tank 2 through the feed pipe 17, and then the motor 4 installed on the bracket 5 is turned on. The motor 4 drives the mixing rod 6 to rotate, thereby driving the mixing disk 19 to rotate, thereby realizing the mixing process. At the same time, the mixing rod 6 drives the connecting tube 20 and the scraper 7 to rotate through the connecting rod 8, thereby driving the scraper 7 to scrape off the raw materials adhered to the inner wall of the mixing tank 2, thereby realizing sufficient mixing of the raw materials. After mixing, the mixed raw materials are transported to an external storage device through the discharge pipe 18. When the raw materials in the mixing tank 2 are too viscous or begin to solidify, the mixing disk 19 and the scraper 7 receive resistance. When the resistance is too large, due to the limit Due to the rounded corner design at the edges of the groove 12 and the limit plate 11, the side wall of the limit groove 12 will squeeze the limit plate 11, so that the limit plate 11 compresses the push spring 13 connected to one side, and then the limit plate 11 will detach from the limit groove 12. Since the rotating plate 15 is movably installed in the rotating groove 16, the connecting sleeve 9 will continue to rotate with the motor 4. The mixing disk 19 and the scraper 7 cannot continue to rotate due to resistance. At this time, the motor 4 will drive the plug-in rod 10 through the setting of the rotating groove 16 through the connecting sleeve 9 to idle, and then the connecting rod 14 and the mixing rod 6 will not continue to rotate, thereby effectively preventing the mixing rod 6 from breaking, and then sufficient time can be left for the staff to turn off the motor 4 to adjust the equipment.

[0043] When the mixing rod 6 needs to be replaced or maintained as a whole, the tank cover 3 is removed from the top of the mixing tank 2, and then the drawstrings 28 set on both sides are pulled, and the drawstrings 28 will drive the matching block 23 to rotate on the outside of the connecting sleeve 9, and at the same time, the matching block 23 will squeeze the spring 29 set on one side, and then the matching block 23 will drive the matching groove 21 to move. Due to the special structural design of the matching groove 21 and the matching plate 22, when the matching block 23 moves, the matching block 23 will drive the matching plate 22 to move outward through the matching groove 21, and then the matching plate 22 will drive the plug-in frame 2 4 moves outward, and the plug-in frame 24 will gradually disengage from the plug-in slot 25. When the pull belt 28 cannot be pulled, the spring 29 is compressed to the limit, and one end of the plug-in frame 24 is completely disengaged from the plug-in slot 25. Then, the mixing rod 6 can be pulled downward to pull the plug-in rod 10 and the connecting rod 14 out of the connecting sleeve 9, thereby realizing the removal of the mixing rod 6.
