[0025] Embodiment: As Figures 1-7As shown in the figure, the utility model provides a mixer for preparing anti-cracking and anti-corrosion concrete admixtures. The mixer includes a mixing tank 1, an equipment box 11, a feeding hopper 12, a discharge pipe 13, a stirring motor 14, a stirring shaft 15, a paddle group 151 and a base 16. The mixing tank 1 is assembled on the base 16. The equipment box 11 and the feeding hopper 12 are assembled at one end of the mixing tank 1. The discharge pipe 13 is assembled at the other end of the mixing tank 1. The stirring motor 14 is assembled on the equipment box 11. One end of the stirring shaft 15 is fixedly connected to the drive shaft of the stirring motor 14. The bushing of the paddle group 151 is slidably installed on the stirring shaft 15. The bushing of the paddle group 151 is clamped on the outer wall of the stirring shaft 15 by a clamping block. Thus, the bushing of the paddle group 151 can slide vertically on the outer wall of the stirring shaft 15. At the same time, the stirring shaft 15 can make the paddle group 151 rotate. When water reducing agent, air entraining agent, setting retarder, early strength agent, waterproof agent, antifreeze agent and expansive agent required for preparing anti-cracking and anti-corrosion concrete admixtures are added into the interior of the mixing tank 1 through the feeding hopper 12, the drive shaft of the stirring motor 14 can make the paddle group 151 rotate through the stirring shaft 15. The paddle group 151 stirs and mixes the proportioning solvents in the mixing tank 1. This is the prior art and will not be elaborated here;

[0026] A lifting mechanism 2 is provided on the mixing tank 1 and the equipment box 11. By setting the lifting mechanism 2, the lifting mechanism 2 can make the paddle group 151 reciprocate up and down, so as to fully stir the proportioning solvents in the mixing tank 1, thereby improving the stirring effect and the quality of the prepared anti-cracking and anti-corrosion concrete admixtures. A mixing mechanism 4 is provided in the feeding hopper 12. By setting the mixing mechanism 4, the mixing mechanism 4 can pre-mix various proportioning agents added in the feeding hopper 12 and mix the proportioning agents evenly, so as to reduce the subsequent stirring and mixing time, thereby improving the preparation efficiency of the anti-cracking and anti-corrosion concrete admixtures;

[0027] The lifting mechanism 2 includes a counterweight sleeve 21. The bushing of the blade group 151 passes through the counterweight sleeve 21 and is rotatably connected to the inner wall of the counterweight sleeve 21. A lifting rod 23 is slidably arranged inside the mixing tank 1. One end of the lifting rod 23 is fixedly connected to the outer wall of the counterweight sleeve 21. A pull rope 26 is fixedly installed in the middle of the lifting rod 23. By winding up the pull rope 26, the pull rope 26 can vertically lift the counterweight sleeve 21 through the lifting rod 23. The counterweight sleeve 21 can vertically lift the blade group 151 on the stirring shaft 15 through the bushing of the blade group 151. During the process of the blade group 151 rotating and rising synchronously, the proportioning solvent in the mixing tank 1 is stirred and mixed. One end of the equipment box 11 is fixedly provided with a servo motor 27. The driving output end of the servo motor 27 is fixedly installed with a rotating rod 29. One end of the rotating rod 29 is rotatably connected to one end of the equipment box 11. One end of the rotating rod 29 is fixedly installed with a winding roller 3. The end of the pull rope 26 far from the lifting rod 23 is wound and connected to the winding roller 3. By turning on the servo motor 27, the driving shaft of the servo motor 27 can make the winding roller 3 rotate through the rotating rod 29. The winding roller 3 can wind and unwind the pull rope 26. When unwinding, the counterweight sleeve 21 drops downward by its own gravity, so that the blade group 151 descends synchronously.

[0028] A guide rod 24 is fixedly installed on the inner wall of the mixing tank 1. A sliding sleeve 25 is slidably installed at one end of the guide rod 24. The other end of the lifting rod 23 is fixedly connected to the outer wall of the sliding sleeve 25. By providing the sliding sleeve 25 and the guide rod 24, the sliding sleeve 25 can vertically slide on the guide rod 24, so as to enable the lifting rod 23 and the counterweight sleeve 21 to lift in the vertical direction.

[0029] The fixed end of the servo motor 27 is fixedly installed with an L-shaped support frame 28. One end of the L-shaped support frame 28 is fixedly connected to one end of the equipment box 11. By providing the L-shaped support frame 28, the L-shaped support frame 28 can support and fix the servo motor 27.

[0030] A guide sleeve 31 is slidably arranged inside the equipment box 11. The end of the pull rope 26 close to the winding roller 3 passes through the guide sleeve 31 and is in movable contact with the inner wall of the guide sleeve 31. By providing the guide sleeve 31, the guide sleeve 31 can guide the pull rope 26, so that the unwound pull rope 26 is always above the lifting rod 23.

[0031] A connecting rod 32 is fixedly installed on the outer wall of the guide sleeve 31. A guide groove 33 is provided on the side wall of the equipment box 11. A guide block 34 is slidably installed at one end of the guide groove 33. One end of the connecting rod 32 far from the guide sleeve 31 is fixedly connected to one side of the guide block 34. By providing the guide groove 33 and the guide block 34, the guide block 34 can horizontally slide along the inner wall of the guide groove 33, so as to horizontally guide the guide sleeve 31 through the connecting rod 32. During the winding and unwinding process of the pull rope 26, the pull rope 26 makes the guide sleeve 31 horizontally move.

[0032] The mixing mechanism 4 includes a rotating shaft 41. One end of the rotating shaft 41 is rotatably connected to one side of the feeding hopper 12. A fixed roller 42 is fixedly installed at one end of the rotating shaft 41. A number of blades 43 are fixedly installed on the outer wall of the fixed roller 42 and are distributed in an annular array. By driving the rotation of the rotating shaft 41, the rotating shaft 41 can make the blades 43 rotate through the fixed roller 42, and the blades 43 can pre-mix the proportioning agents added in the feeding hopper 12.

[0033] Synchronous wheels 44 are fixedly installed at one end of the rotating rod 29 close to the servo motor 27 and at one end of the rotating shaft 41 away from the fixed roller 42. A synchronous belt 45 is installed between the two synchronous wheels 44 for transmission. When the rotating rod 29 rotates, the rotating rod 29 can make the rotating shaft 41 rotate synchronously through the two synchronous wheels 44 and the synchronous belt 45.

[0034] Working principle: When preparing the crack-resistant and corrosion-resistant concrete admixture, the operator first adds the water required for preparing the admixture into the mixing tank 1 through the feeding hopper 12, and then adds the water-reducing agent, air-entraining agent, setting retarder, early-strength agent, waterproofing agent, anti-freezing agent and expansive agent into the feeding hopper 12 (the types and amounts of the proportioning agents are determined according to the type of the prepared admixture). At the same time, the operator synchronously turns on the servo motor 27 and the stirring motor 14. The drive shaft of the stirring motor 14 makes the paddle group 151 rotate through the stirring shaft 15, the drive shaft of the servo motor 27 makes the rotating rod 29 rotate, the rotating rod 29 makes the rotating shaft 41 rotate synchronously through the two synchronous wheels 44 and the synchronous belt 45, and the rotating shaft 41 makes the multiple blades 43 rotate through the fixed roller 42. The multiple blades 43 pre-mix the various proportioning agents added during the rotation process, thereby reducing the stirring and mixing time of the subsequent admixture preparation operation, and then improving the preparation efficiency of the crack-resistant and corrosion-resistant concrete admixture;

[0035] Meanwhile, the rotating rod 29 winds up the pulling rope 26 through the winding roller 3. The pulling rope 26 makes the lifting rod 23 and the counterweight sleeve 21 rise vertically. The counterweight sleeve 21 makes the paddle group 151 rise vertically on the stirring shaft 15 through the shaft sleeve of the paddle group 151. When the paddle group 151 rises to the top of the stirring shaft 15, the drive shaft of the servo motor 27 rotates in the reverse direction. At this time, the pulling rope 26 is unwound. With the cooperation of the counterweight sleeve 21, the counterweight sleeve 21 makes the paddle group 151 descend vertically on the stirring shaft 15 through the shaft sleeve of the paddle group 151. During this process, the paddle group 151 stirs and mixes the proportioning solvent in the mixing tank 1 during the rotation and synchronous reciprocating lifting process, so as to fully stir the proportioning solvent in the mixing tank 1, and then improve the stirring effect and the quality of the prepared crack-resistant and corrosion-resistant concrete admixture.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
