The mixing blocks are cones with a tip, the tip pointing in the same direction as the rotation of the connecting rod. During mixing operations, the external drive device drives the connecting rod to rotate, thereby driving the mixing blocks to rotate, and the rotating mixing blocks break up the lumps of concrete. The concrete mixing plant of this application solves the problem that traditional square mixing blades are inconvenient to break up lumps of concrete during mixing by setting up mixing blocks to break up the concrete."
[0004] When using the above technology, the following technical problems were found in the prior art: When using the above device, since the mixing block is cone-shaped and the tip is oriented in the same direction as the rotation of the connecting rod, concrete residue is easily generated in the mixing chamber. After mixing is completed, the residual concrete may form hard lumps that are difficult to remove inside the device, increasing the maintenance cost of the device. Utility Model Content

After mixing is completed, the residual concrete may form hard lumps that are difficult to remove inside the device, increasing the maintenance cost of the device.

[0026] Example 1
[0027] like Figure 1 - Figure 6 As shown, an indoor concrete mixing device for building decoration includes a mixing device housing 1. A servo motor 12 is installed on one side of the outer side of the mixing device housing 1. A rotating shaft 13 is fixedly connected to the output end of the servo motor 12. The rotating shaft 13 is located inside the mixing device housing 1. Multiple sets of mixing claws 14 are fixedly connected to the outer side of the rotating shaft 13. A rotary joint 15 is installed at the end of the rotating shaft 13 away from the servo motor 12. A water supply pipe 11 is installed at the end of the rotary joint 15. A cleaning component is provided inside the rotating shaft 13. The cleaning component cooperates with the water supply pipe 11 and the rotary joint 15. A vibration component is installed on the outer side of the mixing device housing 1 near the rotary joint 15. A discharge component is provided inside the mixing device housing 1.
[0028] During operation, the mixing device housing 1 is first moved to the working position, and then the concrete raw materials are injected into the mixing device housing 1. At this time, the drive servo motor 12 drives the rotating shaft 13 and the mixing claw 14 to rotate, mixing and blending the concrete. During the mixing process, the vibration component works. After the mixing is completed, the concrete is discharged from the mixing device housing 1 through the discharge component. Then, the cleaning component is activated to clean the inside of the mixing device housing 1. Through the action of the cleaning component and the vibration component, the continuous vibration during the concrete mixing process makes the concrete more evenly mixed. At the same time, the continuous vibration generated when the cleaning component cleans the inside of the mixing device housing 1 further improves the working efficiency of the cleaning component and further reduces the increase in maintenance costs caused by the hardening of residual concrete after the device is completed.
[0029] Example 2
[0030] like Figure 1 - Figure 6As shown, the cleaning assembly includes a water nozzle 2 located outside the rotating shaft 13. A clogging roller 21 is installed inside the rotating shaft 13. To enhance the strength of the clogging roller 21, a reinforcing frame 22 is fixedly connected inside the clogging roller 21. A rotating ring 23 is rotatably connected to the side of the rotating shaft 13 near the water supply pipe 11. A limiting groove 25 is formed on one side of the rotating ring 23. A limiting tooth 24 is fixedly connected to the outer side of the rotating shaft 13 near the limiting groove 25. The limiting tooth 24 meshes with the limiting groove 25. A spring ring 26 is installed at the end of the device. The end of the spring ring 26 away from the rotating shaft 13 is fixedly connected to the rotating ring 23. A sliding block 27 is fixedly connected to one side of the rotating ring 23. A groove 28 is opened at the end of the blocking roller 21 near the rotating ring 23. The sliding block 27 slides inside the groove 28. The vibration assembly includes a fixed ring 3 on the outer side of the stirring device housing 1. The fixed ring 3 is fixedly connected to the outer side of the stirring device housing 1. Multiple sets of vibration rods 31 are fixedly connected inside the fixed ring 3. A rotating gear 32 is fixedly connected to the outer side of the rotating shaft 13 near the fixed ring 3. The discharge assembly includes a discharge port 4 located inside the stirring device housing 1. A baffle 41 is rotatably connected inside the stirring device housing 1 near the discharge port 4. A lever 42 is installed at the end of the baffle 41 near the outer side of the stirring device housing 1. A limit block 43 is installed at the end of the stirring device housing 1 near the lever 42.
[0031] During operation, when the concrete begins to mix, the servo motor 12 drives the rotating shaft 13 to rotate continuously. At this time, the rotating gear 32 on the outside of the rotating shaft 13 continuously moves and impacts the vibrating rod 31 inside the fixed ring 3. The resulting vibration is transmitted into the mixing device housing 1, vibrating the concrete and increasing its uniformity. After mixing is complete, the lever 42 is moved, causing the baffle 41 to move inside the mixing device housing 1, opening the discharge port 4. Then, the lever 42 is engaged with the limiting block 43. After the concrete is discharged from the mixing device housing 1, the rotating ring 23 is pulled, causing the limiting groove 25 to disengage from the limiting tooth 24, and then rotation begins. When the spring ring 26 is stretched, it begins to deform the outer shell 1 of the stirring device. When the rotating ring 23 rotates, the spring ring 26 also rotates at one end of the rotating shaft 13. Since the sliding block 27 and the sliding groove 28 are slidably connected, when the rotating ring 23 rotates, the blocking roller 21 rotates with the rotating ring 23, thus removing the blocking roller 21 from the water spray nozzle 2. At this time, water is injected into the blocking roller 21 through the water supply pipe 11 and then sprayed out through the water spray nozzle 2. At the same time, the servo motor 12 drives the rotating shaft 13 to rotate, which increases the cleaning of the inner wall of the stirring device outer shell 1. After cleaning, the wastewater is discharged through the discharge port 4. After cleaning, the lever 42 is disengaged from the limit block 43, and the discharge port 4 is resealed.
[0032] Example 3
[0033] like Figure 1 - Figure 2As shown, an inclined plate 5 is fixed to the bottom of the inner side of the mixing device shell 1, so that after the concrete is mixed, it automatically approaches the discharge port 4 to facilitate the discharge of the concrete. A splash cover 6 is installed on the top of the mixing device shell 1.
[0034] During operation, in order to reduce concrete splashing during the concrete mixing process, the splash cover 6 blocks the concrete splashed from the outer shell 1 of the mixing device, thereby reducing the pollution of the working environment caused by concrete splashing.
