DETAILED DESCRIPTION

[0019] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0020] like Figure 1-6 As shown, a concrete admixture dry mixing device comprises a tank body 1 and a cover body 2 arranged on the tank body 1, a discharging portion is arranged at the lower end of the tank body 1, a driving motor 3 is arranged at the upper end of the cover body 2, a stirring assembly 4 is arranged after the output end of the driving motor 3 passes through the cover body 2, and further comprises a supporting frame 5 arranged below the tank body 1, guide portions are arranged on both sides of the supporting frame 5, the two guide portions are connected by a fixing frame 6, the guiding portion comprises vertical poles 7 symmetrically arranged on the supporting frame 5, a mounting frame 8 is arranged at the middle position of the two vertical poles 7, a gear 9 is arranged on the mounting frame 8, and gears 9 are arranged on the two vertical poles 7. A first straight rack 10 and a second straight rack 11 are respectively slidably connected, both sides of the tank body 1 are fixedly connected to the first straight rack 10 through a first connecting plate 12, and both sides of the cover body 2 are fixedly connected to the second straight rack 11 through a second connecting plate 13. The upper end of the first straight rack 10 and the tank body 1 are respectively located on both sides of the mounting frame 8, and the lower end of the second straight rack 11 and the cover body 2 are respectively located on both sides of the mounting frame 8. An extension plate 14 is provided on one side of the first straight rack 10, and electric telescopic rods 15 are respectively provided on both sides of the fixed frame 6, and the output end of the electric telescopic rod 15 is fixedly connected to the extension plate 14.

[0021] The upper end of the tank body 1 is open, and concrete and admixtures are put into the tank body 1 through the upper end opening. Since concrete and admixtures are both powdered and small granular materials, a lot of dust will be generated in the air during the dry mixing process. The cover body 2 is placed at the upper end opening of the tank body 1 to reduce the overflow of dust.

[0022] The support frame 5, the vertical pole 7, and the fixed frame 6 are all made of aluminum alloy profiles. The outer surface of the aluminum alloy profile has a card slot. One side of the first straight rack 10 and the second straight rack 11 respectively has a card strip that matches the card slot, so that the first straight rack 10 and the second straight rack 11 can only move up and down along the vertical pole 7, and the first connecting plate 12 and the second connecting plate 13 at both ends also have a card strip that matches the card slot on the outer surface of the vertical pole 7, thereby improving the connection stability between the first connecting plate 12 and the first straight rack 10 and the second connecting plate 13 and the second straight rack 11. The mounting frame 8 is fixed on the two vertical poles. Between the rods 7, the gear 9 can rotate on the mounting frame 8. When the first spur rack 10 moves downward, it drives the second spur rack 11 to move upward by meshing with the gear 9. Since the tank body 1 and the first spur rack 10 are fixedly connected by the first connecting plate 12, and the cover body 2 and the second spur rack 11 are fixedly connected by the second connecting plate 13, the tank body 1 will move downward with the first spur rack 10, and the cover body 2 will move upward with the second spur rack 11, so that the tank body 1 and the cover body 2 are separated. When the tank body 1 and the cover body 2 are separated, concrete and admixtures can be put into the tank body 1.

[0023] Working principle: When in use, the device is in Figure 3 state, put concrete and admixture into the tank body 1. After the putting is completed, the output end of the electric telescopic rod 15 is controlled to retract, driving the extension plate 14 to move upward. Since the extension plate 14 is fixedly connected to the first spur rack 10, the first spur rack 10 will also move upward. The first spur rack 10 drives the second spur rack 11 to move downward through the cooperation of the gear 9, so that the tank body 1 moves upward and the cover body 2 moves downward. When the tank body 1 is docked with the cover body 2, the electric telescopic rod 15 stops working. At this time, the closure of the tank body 1 is completed, and then the stirring assembly 4 is driven by the driving motor 3 to realize the stirring of the raw materials in the tank body 1. After the stirring is completed, the material can be discharged through the discharge part below the tank body 1.

[0024] Furthermore, the discharge part includes a discharge pipe 16 which is connected to the lower end of the tank body 1, and a slot 17 is provided in the middle position of the discharge pipe 16. The slot 17 is provided with a through hole which is connected to the discharge pipe 16. A plug plate 18 is slidably connected to the inside of the slot 17. The plug plate 18 includes a closed area and an open area. The plug plate 18 controls the opening and closing of the discharge pipe 16 through the closed area and the open area. A handle groove 19 is provided on one side of the plug plate 18. When the open area on the plug plate 18 and the through hole on the slot 17 are connected to each other, the concrete and admixture in the tank body 1 can be discharged downward through the discharge pipe 16. When the closed area on the plug plate 18 is in the through hole area of ​​the slot 17, the discharge pipe 16 is in a closed state, and the material in the tank body 1 cannot be discharged. The handle groove 19 facilitates the control of the movement of the plug plate 18 in the slot 17.

[0025] Furthermore, a limit frame 20 is provided on one side of the slot 17. When one end of the handle slot 19 contacts the limit frame 20, it means that the opening area on the plug board 18 and the through hole on the slot 17 are interconnected, which facilitates observation and control of the position of the opening area on the plug board 18 and improves work efficiency.

[0026] Furthermore, a placement plate 21 is slidably connected to the bottom of the support frame 5, and a handle 22 is provided on the placement plate 21. The bottom of the placement plate 21 also has a card strip that matches the card slot on the aluminum alloy profile that constitutes the support frame 5, so that the placement plate 21 can be moved on the support frame 5, and the position of the placement plate 21 can be controlled by the handle 22. By placing a container such as a cylinder on the placement plate 21, and then moving the placement plate 21 to the bottom of the tank body 1, after the concrete admixture is put into the container through the discharge pipe 16, the discharge pipe 16 is closed, and then the placement plate 21 is pushed further away by the handle 22, so that it is easy to take out the container on the placement plate 21.

[0027] Furthermore, a reinforcing rod 23 is provided between the upright pole 7 and the supporting frame 5 , and the reinforcing rod 23 can improve the stability of the upright pole 7 .

[0028] The device can move and adjust the tank body 1 to a lower position when adding concrete admixture into the tank body 1, thereby improving the convenience of adding materials. When stirring, the tank body 1 can be moved to a higher position, which is convenient for subsequent discharge and also easy to close the upper end opening of the tank body 1, thereby reducing dust overflow, improving the convenience of adding and discharging materials, and having a good use effect.
