When the device is used to compound concrete additives, the user first adds the mother liquid into the mixing barrel 41 from the feed port 43, and then moves the third connecting rod 32 to the right, thereby removing the two latch rods 33 from the round rod 23. At this time, the user lifts the inner cover 31 upwards, and the inner cover 31 will be separated from the upper end of the premixing barrel 21. The user then puts a variety of additives into the premixing barrel 21. After the addition is completed, the user can put the inner cover 31 back to its original position, and then control the servo motor 11 to work. At this time, the servo motor 11 drives the rotating shaft 15 to rotate through the output shaft. The rotating shaft 15 will drive the first connecting rod 12 and the second connecting rod 13 as well as the rotating ring 16 and the second stirring rod 17 to rotate. At this time, the rotating ring 16 and the second stirring rod 17 will stir the mother liquid to keep it in a flowing state. While the rotating shaft 15 is rotating, the two sets of A stirring rod 14 will also rotate, and at this time, the two groups of first stirring rods 14 will stir the various additives in the premixing barrel 21. At this time, the equipment has completed the premixing of concrete additives. The new type is convenient for stirring the various additives in the premixing barrel 21 by setting the premixing barrel 21 inside the stirring barrel 41, and the rotating shaft 15 and the two groups of first stirring rods 14 are set inside the premixing barrel 21, so that they are fully mixed, so that the various additives can be premixed first, and then they are mixed with the mother liquor, which is beneficial to improve the compounding efficiency.

[0026] A premixing barrel 21 is fixedly installed inside the mixing barrel 41. Two through holes are provided on the circumferential surface of the premixing barrel 21.

Moreover, the mother liquor inside the stirring barrel 41 is in a flowing state under the inertia of the rotating ring 16 and the second stirring rod 17, which can effectively improve the mixing efficiency between various additives and the mother liquor.

[0027] Working principle:

[0028] In the first step, when the device is compounding concrete additives, the user first adds the mother liquid into the mixing barrel 41 from the feed port 43, and then moves the third connecting rod 32 to the right, thereby removing the two latch rods 33 from the round rod 23. At this time, the user lifts up the inner cover 31, and the inner cover 31 will be separated from the upper end of the premixing barrel 21. At this time, the user puts a variety of additives into the interior of the premixing barrel 21. After the addition is completed, the user can cover the inner cover 31 back to its original position, and then control the servo motor 11 to work. At this time, the servo motor 11 drives the rotating shaft 15 to rotate through the output shaft. The rotating shaft 15 will drive the first connecting rod 12 and the second connecting rod 13 as well as the rotating ring 16 and the second stirring rod 17 to rotate.

Therefore, various additives can be premixed first, so that they can be mixed with the mother liquor, which is beneficial to improving the compounding efficiency.

[0029] In the second step, after the premixing of various additives is completed, the user can move the third connecting rod 32, so that the two latch rods 33 are inserted into the inside of the two round rods 23. At this time, the user moves the inner cover 31 upwards again, and the inner cover 31 will drive the two round rods 23 to move upward, and the two round rods 23 will drive the two openable baffles 22 to move upward. At this time, the additives located inside the premixing barrel 21 and premixed will flow into the mother liquor inside the stirring barrel 41. The present invention uses two openable baffles 22 that can move up and down on the premixing barrel 21, so that the premixing barrel 21 can be connected with the inside of the stirring barrel 41 at any time, and the inside of the premixing barrel 21 can be opened by only lifting the inner cover 31. Moreover, the mother liquor inside the stirring barrel 41 is also in a flowing state under the inertia of the rotating ring 16 and the second stirring rod 17, which can effectively improve the mixing efficiency between various additives and the mother liquor.
