[0026] Reference will now be made to Figures 1-6This utility model provides a technical solution:

[0027] A concrete water-reducing agent mixing device includes a main body 1, a mixing unit 2, a controller 3, a liquid addition unit 4, and a liquid distribution module 5. The main body 1 includes a shell 11, a support base 12 is installed on the lower side of the shell 11, a feeding hopper 14 is connected to the upper left side of the shell 11, and a discharge valve pipe 13 is connected to the lower side of the shell 11. The mixing unit 2 includes a motor 21 fixed to the upper side of the shell 11. The output shaft of the motor 21 passes through the upper shell plate of the shell 11 and is fixedly connected to a rotating shaft 22. An impeller 23 located inside the shell 11 is fixedly connected to the outer side of the rotating shaft 22. The controller 3 is installed on the right side of the shell 11. The liquid distribution module 5 includes an annular shell 51 fixed to the outer side of the rotating shaft 22. A transmission pipe 52 is connected to the left side of the annular shell 51. Multiple diversion ports 53 are opened at the lower tube plate of the transmission pipe 52, and the diversion ports 53 are all arranged at equal intervals. A liquid outlet head 54 is connected to the lower side of each diversion port 53.

[0028] The liquid filling unit 4 includes a liquid filling hopper 41 fixed to the upper side of the outer casing 11. A bend tube 42 is connected to the lower side of the liquid filling hopper 41. The lower end of the bend tube 42 passes through the upper shell plate of the outer casing 11 and is connected to an annular cover 43. This arrangement allows the liquid filling unit 4 to deliver water-reducing agent to the annular cover 51. The liquid outlet head 54 includes a liquid storage shell 541 fixedly connected to the transmission pipe 52. An outlet hole 542 is opened at the rear shell plate of the liquid storage shell 541. Guide holes 543 are symmetrically opened at the rear shell plate of the liquid storage shell 541 on both sides of the outlet hole 542. The front end face of the liquid storage shell 541 is fixed. A fixing ring 544 is connected, and an electromagnet 545 is fixedly connected to the inner side of the fixing ring 544. Guide rods 546 are slidably connected to the inner side of each guide hole 543. A connecting strip 547 is connected to the front end of a set of guide rods 546, and the connecting strip 547 is located inside the liquid storage shell 541. A metal sheet 548 is fixedly connected to the notch on the front side of the connecting strip 547. A sealing cap 549 is fixedly connected to the rear end of a set of guide rods 546. A power supply 55 is installed on the lower side of the ring shell 51. This configuration allows the liquid outlet 54 to store the dispensed water-reducing agent. It can be opened or closed as needed by the staff; the ring cover 43 is located inside the ring shell 51, and the ring cover 43 is slidably connected to the ring shell 51. This setting prevents external impurities from entering the ring shell 51 and ensures that the rotation of the ring shell 51 is not affected by the ring cover 43. The power supply 55 is wirelessly connected to the controller 3, and the power supply 55 is electrically connected to each electromagnet 545. This setting allows the controller 3 to control the power supply 55 to turn the electromagnets 545 on and off; the liquid separation module 5 is located on the upper side of the impeller 23, and the electromagnets 545 and The metal sheets 548 are aligned front to back, which allows the electromagnet 545 to magnetically attract the metal sheets 548 when energized. The sealing cover 549 is located inside the outlet hole 542, and the inner wall of the outlet hole 542 fits against the outer curved surface of the sealing cover 549. This allows the sealing cover 549 to seal the outlet hole 542. A counterweight is provided on the rear side of the sealing cover 549. This allows the sealing cover 549 to be more easily thrown out with rotation when the electromagnet 545 is de-energized and no longer positions the sealing cover 549.

[0029] Workflow: The mixing operation of the concrete water-reducing agent mixing device is as follows: Note 1: All electrical components of this equipment are externally powered and controlled by controller 3; Note 2: Power supply 55 normally supplies power to each electromagnet 545, ensuring that the electromagnet 545 maintains magnetic attraction to the metal plate 548, thereby keeping the sealing cover 549 sealed to the outlet 542; First, concrete is poured into the outer shell 11 through the feeding hopper 14. At this time, controller 3 starts motor 21, which drives the rotating shaft 22 to rotate, thereby driving impeller 23 to mix the concrete. Next, an appropriate amount of water-reducing agent is added to the liquid addition hopper 41. The water-reducing agent flows into the ring shell 51 of the liquid distribution module 5 through the bend pipe 42, and then enters the transmission pipe 52. In the transmission pipe 52, the water-reducing agent is evenly distributed to the liquid storage shell 541 of each liquid outlet 54 through the diversion port 53. After the water-reducing agent is distributed, the controller 3 wirelessly controls the power supply 55 to de-energize each electromagnet 545, so that the electromagnets 545 no longer magnetically attract the metal sheet 548, thus allowing the sealing cover 549 to move freely. At this time, due to the counterclockwise rotation of the rotating shaft 22, the ring shell 51, the transmission pipe 52 and the liquid outlet 54 are rotated, which throws the sealing cover 549 of each liquid outlet 54 out of the outlet hole 542, so that each outlet hole 542 opens at the same time. In this way, the water-reducing agent in each liquid storage shell 541 is discharged from the outlet hole 542 and evenly spread on the surface of the concrete with the rotation of the transmission pipe 52. Finally, with the stirring of the impeller 23, the concrete and the water-reducing agent are evenly mixed, realizing the effective mixing of the water-reducing agent. This realizes the ability of the mixing device to evenly distribute the water-reducing agent and fully mix the water-reducing agent with the concrete.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
