[0017] The present invention adopts the above technical solution to bring the following beneficial effects:

[0018] 1. This kind of active powder concrete mixing station starts with a motor to drive the first rotating rod to rotate, and the circular gear set drives the rotating drum to start rotating. The three sealed boxes evenly distributed on the rotating drum rotate synchronously, and the four second rotating rods arranged around each sealed box also rotate, and the flip plate on the outer wall performs preliminary mixing on the concrete. At the same time, the conical gear set between the second rotating rod and the fixed rod allows the second rotating rod to achieve self-rotation while revolving, driving the flip plate to flip the concrete from different angles. This mixing method combining revolution and rotation enables the concrete to be fully mixed in the tank body, and the various components are evenly mixed, effectively avoiding the problems of local component differences and mixing blind spots, and greatly improving the mixing uniformity.

[0019] 2. In this active powder concrete mixing station, during the mixing process, the elastic rod fixed at one end of the second rotating rod at the bottom rotates with the rod, and collides with the protrusion fixed on the inner wall of the tank body when it is at the same horizontal height. The generated vibration is transmitted to the entire tank body, causing the concrete to vibrate. At the same time, the vibrating rod installed on the partition is started to vibrate the concrete. These two vibration methods cooperate with each other to effectively expel the air inside the concrete. The concrete after the air is expelled is more compact, the pores and bubble content are greatly reduced, and its structural compactness is significantly enhanced, thereby improving the strength and durability of the concrete, effectively preventing problems such as loose structure, decreased impermeability and frost resistance caused by residual air, and ensuring the overall quality and performance consistency of the concrete.

[0020] 3. In this active powder concrete mixing station, when the drum rotates, the rotating plate on the outer wall and the arc block on the top thereof make circular motions. The arc block interacts with the movable plate during the motion. Due to the elastic support of the first spring, the movable plate drives the movable rod to move up and down, thereby causing the vibrating rod installed in the mounting frame on the inner wall of the circular ring to move up and down. This up and down vibration mode makes the vibrating rod vibrate the concrete more evenly and deeply, further enhancing the density of the concrete, just like compacting the concrete with a more powerful "fist", making its internal structure more solid and reliable.

[0021] 4. This kind of active powder concrete mixing station plays a key role in the mixing process through the two dispersion combs fixed on the inner wall of the ring. When the concrete flows through the dispersion comb under the action of the flip plate, the comb teeth divide the concrete flow into many small streams, breaking the block or cluster structure that may exist in it, and promoting the cement, aggregate and admixture and other components to contact and mix more fully, which not only further improves the uniformity of mixing, but also makes the microstructure of concrete more uniform and stable, laying the foundation for its high performance.

[0022] 5. In this active powder concrete mixing station, the rotation of the rotating drum drives the three guide plates arranged around the lower part of the outer wall to rotate synchronously. The guide plates not only re-mix the concrete at the bottom of the tank body to improve the mixing effect, but also guide the concrete on the outer periphery of the bottom to the middle, so that the concrete can flow to the discharge pipe more smoothly, which is convenient for discharging and avoids the problem that the concrete accumulates at the bottom of the tank body and affects the discharging speed and uniformity. Through the cooperation of the baffle plate, the limit groove and the limit block, the rotating rod is driven to rotate, and the spiral rod at the bottom of the rotating rod rotates accordingly to stir the concrete at the discharging place to prevent the concrete from clogging the discharging pipe during the discharging process. At the same time, when the rotating rod rotates, the inclined block on the top, under the action of the pressure rod at the bottom of the fixed rod, cooperates with the extension and contraction of the second spring to move the rotating rod up and down. When the spiral rod moves up and down, the pointed cone below it continuously knocks on the concrete, further improving the speed and stability of concrete discharging and ensuring that the discharging process is efficient and smooth.

At the same time, after the mixing is completed, the rotation of the guide plate 71 will push the concrete to the central area, thereby facilitating the discharge of the concrete. At the same time, the rotating drum 53 drives the rotating rod 73 to rotate under the action of the limit groove 77 and the limit block 78, and then drives the spiral rod 79 to rotate, so as to stir the concrete at the discharge point to avoid concrete blockage. When the rotating rod 73 rotates, it will drive the upper inclined block 75 to rotate, thereby driving the rotating rod 73 to move up and down under the action of the pressure rod 76 and the second spring 74, thereby driving the spiral rod 79 to move up and down, thereby knocking the concrete through the pointed cone under the spiral rod 79, thereby improving the speed and stability of concrete discharge.
