DETAILED DESCRIPTION

[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a water reducing agent mixing device, including a mixing chamber 1, a supporting leg 2 is installed at the bottom end of the mixing chamber 1, a buffer mechanism is arranged inside the supporting leg 2, a discharge pipe 3 is installed at the middle position of the bottom end of the mixing chamber 1, a cover plate 4 is installed at the top end of the mixing chamber 1, a feed port 5 is installed at the top end of the cover plate 4, and a stirring mechanism is arranged inside the mixing chamber 1.

[0019] The stirring mechanism includes a servo motor 6, a driving gear 7, a transmission gear 8, a first rotating shaft 9, a first stirring shaft 10, a second rotating shaft 11, a second stirring shaft 12 and a scraping assembly. The servo motor 6 is installed at the top of the cover plate 4, and the driving gear 7 is installed at the bottom of the cover plate 4. The output end of the servo motor 6 is connected to one end of the driving gear 7. The driving gear 7 is meshed with transmission gears 8 on both sides. The transmission gear 8 is rotatably installed on the bottom end of the cover plate 4. The first rotating shaft 9 is installed at the bottom end of one of the transmission gears 8, and the first stirring shaft 10 is installed on the outer side wall of the first rotating shaft 9. The second rotating shaft 11 is installed at the bottom end of the other transmission gear 8, and the second stirring shaft 12 is provided on the outer side wall of the second rotating shaft 11. 2. A plurality of first stirring shafts 10 are arranged on the outer side wall of the first rotating shaft 9, and the plurality of first stirring shafts 10 are evenly spaced on the outer side wall of the first rotating shaft 9. When in use, the servo motor 6 is started to drive the driving gear 7 to rotate. Since the driving gear 7 and the transmission gear 8 are meshed with each other, the driving gear 7 is used to drive the two transmission gears 8 to rotate, and then the first rotating shaft 9 and the second rotating shaft 11 are respectively driven to rotate, so that the first stirring shaft 10 and the second stirring shaft 12 are driven to rotate, and the first stirring shaft 10 and the second stirring shaft 12 are used to stir the water reducer, so that the mixing effect of the water reducer is better, and the mixing efficiency of the water reducer is higher, thereby greatly improving the working efficiency of the device when in use.

[0020] The scraper assembly includes a rotating ring 13, a scraper 14, a limiting groove 15 and a limiting block 16. The rotating ring 13 is installed on the outer wall of the transmission gear 8. The inner wall of the rotating ring 13 is provided with a transmission gear ring. The transmission gear 8 and the rotating ring 13 are meshed with each other. A scraper 14 is installed below the rotating ring 13. The limiting groove 15 is opened inside the cover plate 4. A limiting block 16 is arranged inside the limiting groove 15. The bottom end of the limiting block 16 is connected to the top of the rotating ring 13. Two scrapers 14 are arranged below the rotating ring 13. The two scrapers 14 are symmetrically distributed about the central axis of the rotating ring 13. When in use, since the rotating ring 13 and the transmission gear 8 are meshed with each other, the rotating ring 13 is driven to rotate by the transmission gear 8 under the limitation of the limiting groove 15 and the limiting block 16, so the scraper 14 is driven to rotate, and the scraper 14 is used to scrape the raw materials attached to the inner wall of the mixing chamber 1, and the stirring process is continued, so that the raw materials are not easily wasted.

[0021] The inner diameter of the limit groove 15 is larger than the outer diameter of the limit block 16, and a sliding structure is formed between the limit groove 15 and the limit block 16.

The connecting plate 18 is installed on the top of the damper 17. The top of the connecting plate 18 is connected to the bottom of the mixing chamber 1. The outer wall of the damper 17 is provided with a telescopic spring 19. When in use, the telescopic spring 19 is subjected to the elastic force. With the cooperation of the damper 17, the vibration generated by the mixing chamber 1 is buffered, thereby performing shock-absorbing protection on the mixing chamber 1 and extending the service life of the mixing chamber 1.

[0023] Working principle: the staff first pours the water reducer raw material into the mixing chamber 1 from the feed port 5, and then starts the servo motor 6 to drive the driving gear 7 to rotate. Since the driving gear 7 and the transmission gear 8 are meshed with each other, the driving gear 7 is used to drive the two transmission gears 8 to rotate, and then the first rotating shaft 9 and the second rotating shaft 11 are respectively driven to rotate, so the first stirring shaft 10 and the second stirring shaft 12 are driven to rotate, and the water reducer is stirred by the first stirring shaft 10 and the second stirring shaft 12. Since the rotating ring 13 and the transmission gear 8 are meshed with each other, the rotating ring 13 is driven to rotate by the transmission gear 8 under the limit of the limit groove 15 and the limit block 16, so the scraper 14 is driven to rotate, and the scraper 14 is used to scrape the raw material attached to the inner wall of the mixing chamber 1, and the stirring process is continued. At this time, the telescopic spring 19 is acted upon by the elastic force, and with the cooperation of the damper 17, the vibration generated by the mixing chamber 1 is buffered, and then the mixing chamber 1 is shock-absorbing and protected. After the water reducer is mixed, it can be discharged from the discharge pipe 3.
