Therefore, for the concrete with a relatively deep accumulation, it is impossible to quickly penetrate the water reducing agent sprayed on the top layer to the bottom position. And directly inserting the pipeline into the concrete and then injecting it easily causes the external concrete to enter the pipeline and cause blockage, with a short service life.

Detailed Embodiment

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 4 , the present utility model provides the following technical solutions: a water reducer adding device, including an adding device body. The adding device body includes a top plate 1, a transmission shaft 5, an independent stirring mechanism 11 and a bottom layer spraying mechanism 12. A plurality of support columns 2 are welded to the bottom of the top plate 1. The transmission shaft 5 is inserted through the middle of the top plate 1. A shunt plate 10 is integrally formed at the bottom of the transmission shaft 5. The independent stirring mechanism 11 is welded to the bottom side of the shunt plate 10. The inside of each independent stirring mechanism 11 is of a hollow structure, and the bottom layer spraying mechanism 12 is embedded at the inner bottom of the independent stirring mechanism 11. The bottom end of the bottom layer spraying mechanism 12 is flush with the bottom of the support column 2. This water reducer adding device can be directly used for the prepared concrete on the ground.

[0024] When the utility model is in use, first place the device on the ground and cover the concrete that has been piled up on the ground. When placing it, the independent stirring mechanism 11 will be directly embedded into the concrete in the form of horizontal pushing and pressed on the ground at the bottom. At this time, the motor 4 and the pressure pump 9 at the top can be started. With the help of the pressure pump 9, the water reducing agent is transported along the transmission shaft 5 to each independent stirring mechanism 11 at the bottom. The water reducing agent is sprayed onto the surface and the bottom layer of the concrete through the top layer spray holes 23 and the bottom layer spray holes 21 on the independent stirring mechanism 11. And the bottom spraying mechanism 12 automatically blocks or opens the position of the bottom layer spray holes 21 according to the injection state of the water reducing agent.

[0025] In this embodiment, the surface of the transmission shaft 5 is embedded into the inside of the top plate 1 through a bearing. A transmission gear 6 is key-connected to the surface of the transmission shaft 5. A transmission box 3 is screwed on the surface of the top plate 1. A motor 4 is screwed on the top of the transmission box 3. A strip-shaped notch is formed on the surface of the transmission box 3. The side of the transmission gear 6 is embedded into the inside of the transmission box 3 from the notch on the surface of the transmission box 3. The transmission gear 6 meshes with the gear installed on the output shaft of the motor 4. A docking bearing 7 is sleeved on the top of the transmission shaft 5. The top of the inner ring of the docking bearing 7 is plugged with a conveying pipeline 8. A pressure pump 9 is placed on the surface of the top plate 1. One end of the conveying pipeline 8 is connected to the end of the pressure pump 9. While transporting the water reducing agent through the transmission shaft 5, it also drives the independent stirring mechanism 11 at the bottom to rotate, and realizes the above-mentioned injection process of the water reducing agent during the rotation. And this device can be directly used inside the tank body and on the ground, with high applicability and improved efficiency of adding and mixing.

[0026] Specifically, after starting the motor 4 at the top, the external transmission gear 6 is driven through the gear set structure inside the transmission box 3, and then the entire transmission shaft 5 is driven to rotate. After the transmission shaft 5 rotates, it can drive the bottom flow dividing plate 10 and each independent stirring mechanism 11 to rotate, so as to achieve the purpose of providing a stirring effect while spraying the water reducing agent subsequently. And the pressure pump 9 at the top is used to inject the water reducing agent into the inside of the transmission shaft 5 along the conveying pipeline 8. Cooperating with the docking bearing 7 can ensure that the water reducing agent can enter each independent stirring mechanism 11 in the rotating transmission shaft 5 and the flow dividing plate 10. The transmission box 3 and the internal gear set structure are existing mature technologies and do not belong to the protection scope of the utility model. Therefore, the internal structure thereof will not be described in detail here.

[0027] In this embodiment, the independent stirring mechanism 11 includes an outer sleeve 13 and an inner hose 14. An arc-shaped lever 22 is integrally formed on one side of the outer sleeve 13. Cavities are formed inside both the shunt plate 10 and the transmission shaft 5, and the inside of the transmission shaft 5 is connected to the inside of each independent stirring mechanism 11 through the shunt plate 10. The top of the inner hose 14 is fixed to the inner wall of the outer sleeve 13 as a whole. A top spray hole 23 is formed at the top end of the surface of the outer sleeve 13, and the connection point of the inner hose 14 and the outer sleeve 13 is lower than the bottom of the top spray hole 23. The water reducer conveyed from the top is partially injected directly from the top spray hole 23 and the bottom spray hole 21 towards the concrete on the outside through the independent stirring mechanism 11. Therefore, the water reducer can be injected from the top and bottom of the concrete simultaneously, making the injection and mixing process of the water reducer more efficient and convenient. Specifically, after the shunt plate 10 rotates, the water reducer is injected into the inside of each outer sleeve 13 and directly sprayed out from the top spray hole 23, so that the concrete accumulated below on the outside can be directly sprayed, and the concrete can also be pushed by the arc-shaped lever 22 during the rotation of the independent stirring mechanism 11.

[0028] In this embodiment, the bottom spraying mechanism 12 includes a fixed convex ring 15 and a movable convex ring 19. The fixed convex ring 15 is integrally formed at the bottom of the outer sleeve 13. A guide rod 16 is inserted through the surface of the fixed convex ring 15. A limit plate 17 is integrally formed at the top of the guide rod 16. A spring 18 is sleeved on the surface of the guide rod 16. The bottom end of the guide rod 16 is welded to the surface of the movable convex ring 19. The side of the movable convex ring 19 is in contact with the inner wall of the outer sleeve 13. A pressing convex block 20 is embedded at the bottom of the outer sleeve 13. The end of the inner hose 14 is bonded to the middle position of the movable convex ring 19 as a whole. A bottom spraying mechanism 12 is provided at the bottom of the independent stirring mechanism 11. With the help of the bottom spraying mechanism 12, the bottom spray hole 21 can be directly blocked by pressing when the water reducer is not injected or the injection pressure is low, thereby effectively preventing the concrete from blocking the water reducer outlet part.

[0029] Specifically, when the water reducer is not injected or the pressure is low, the spring 18 extends to press the movable convex ring 19 at the bottom downward until it presses on the ground. At this time, the bottom spray hole 21 can be directly blocked by the ground. When the water reducer with sufficient pressure is conveyed, it can be ejected from the bottom spray hole 21 to push the movable convex ring 19 upward, and the bottom spray hole 21 can be opened. The bottom of the outer sleeve 13 is always abutted against the ground by the pressing convex block 20 at the bottom. Therefore, the ejected water reducer can directly penetrate into the bottom area of the concrete from the gap provided by the side of the pressing convex block 20.

[0030] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic features of the present utility model, the present utility model can be implemented in other specific forms.

[0031] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
