[0020] A spring 15 is fixedly connected between the rectangular rod 14 and the output shaft of the motor 11 to prevent the rectangular rod 14 from sliding downward and disengaging from the rectangular sleeve 13 .

[0024] The connecting ring 36 is located below the slide groove 32 and is provided with a through hole in which a vertical rod 37 is provided for sliding cooperation with the through hole, and a fan-shaped baffle II 38 is fixedly connected to the top of the vertical rod 37; a limit ring 27 is also fixedly connected to the inner wall of the discharge port 26, and the limit ring 27 is located below the annular groove 28.

[0025] The radius of the fan-shaped baffles I 34 and II 38 is equal to the radius of the discharge port 26 , and the radius of the fan-shaped baffle III 39 is smaller than the inner diameter of the limiting ring 27 .

[0026] A method for using a pouring pile grouting device for construction, the method comprising the following steps:

[0027] Step 1: Move the outer shell 22 to above the pouring port, and then pour the concrete in the mud tank truck into the outer shell 22;

[0028] Step 2: Start the motor 11, the motor 11 drives the movable device 3 to rotate, and then rotates through the fan-shaped baffle I 34, the fan-shaped baffle II 38 and the fan-shaped baffle III 39, and stirs the concrete to reduce the bubbles in the concrete.

[0029] The upper and lower end surfaces of the movable baffle 29 are fixedly connected with vertical stirring rods 25. The stirring rods 25 stir the concrete.

[0030] The working principle of the present invention is as follows: when using the present invention, the outer shell 22 is moved to above the pouring port, and then the concrete in the mud tank truck is poured into the outer shell 22. The concrete in the outer shell 22 drives the movable baffle 29 to move downward by gravity, so that a gap is leaked between the movable baffle 29 and the inner wall of the outer shell 22 for the concrete to move downward. During the downward movement of the movable baffle 29, the elastic telescopic rod 24 is also compressed and contracted;

[0031] Then the motor 11 is started, and the rotation of the motor 11 drives the rectangular sleeve 13 to rotate, and then drives the rectangular rod 14 to rotate, and the rectangular rod 14 drives the movable baffle 29 to rotate, and at the same time the rectangular rod 14 also drives the round rod 31 to rotate, and the round rod 31 drives the fan-shaped baffle I 34 to rotate through the slide groove 32, and the round rod 31 also drives the connecting ring 36 to rotate, and then drives the fan-shaped baffle II 38 and the fan-shaped baffle III 39 to rotate. In the process of the movable baffle 29 moving downward, since the movable baffle 29 is fixedly connected to the rectangular rod 14, the movable baffle 29 moves downward, drives the rectangular rod 14 to move downward, and then drives the round rod 31 to move downward. When the round rod 31 moves downward, the slider II 33 on the fan-shaped baffle I 34 slides with the annular groove 28, so the fan-shaped baffle I 34 is always at the current height, and the round rod 31 moves downward to drive The connecting ring 36 moves downward, and the connecting ring 36 moves downward to drive the fan-shaped baffles II 38 and the fan-shaped baffles III 39 to move downward. When the fan-shaped baffles II 38 contact the limit ring 27, the fan-shaped baffles II 38 cannot move downward, and the connecting ring 36 continues to move downward with the round rod 31. The vertical rod 37 at the lower end of the fan-shaped baffles II 38 slides in the perforation on the connecting ring 36. At the same time, the connecting ring 36 drives the fan-shaped baffles III 39 to slide downward. Since there are multiple fan-shaped baffles I 34, fan-shaped baffles II 38 and fan-shaped baffles III 39, when the fan-shaped baffles I 34, fan-shaped baffles II 38 and fan-shaped baffles III 39 are at different heights and the motor 11 keeps rotating, the concrete will be stirred by the fan-shaped baffles I 34, fan-shaped baffles II 38 and fan-shaped baffles III 39 after passing through, so as to reduce internal bubbles.

[0032] When the concrete in the tank truck is used up and waiting for material, as the concrete on the upper end of the movable baffle 29 is less, the pressure on the movable baffle 29 is reduced, and the movable baffle 29 is driven to move upward under the elastic force of the elastic telescopic rod 24, reducing the gap between the movable baffle 29 and the annular baffle 23. At the same time, when the movable baffle 29 moves upward, it drives the round rod 31 to move upward, so that the fan-shaped baffle III 39 approaches the fan-shaped baffle II 38, and finally moves to the same plane. After the fan-shaped baffle III 39 and the fan-shaped baffle II 38 are in the same plane, the space between the fan-shaped baffle III 39 and the fan-shaped baffle II 38 is reduced. The gap is smaller than the gap between two adjacent fan-shaped baffles II 38, so that the discharge amount of concrete per unit time is reduced. When the round rod 31 continues to move upward, the fan-shaped baffles III 39 and the fan-shaped baffles II 38 move to contact the side of the fan-shaped baffle I 34, so that the gap between the fan-shaped baffles III 39 and the fan-shaped baffles I 34 is smaller than the gap between two adjacent fan-shaped baffles I 34 and reaches the minimum, so that the discharge amount of concrete per unit time is further reduced, so as to avoid the concrete in the shell 22 being completely emptied when waiting for material, resulting in ash residue on the upper end of the concrete in the conduit, which ultimately affects the quality of the cast-in-place pile;

[0033] When waiting for materials, the motor 11 rotates to drive the round rod 31 to rotate, and the round rod 31 drives the fan-shaped baffles III39, the fan-shaped baffles II38 and the fan-shaped baffles I34 to rotate together, so that the concrete flowing out from the gap between the fan-shaped baffles III39 and the fan-shaped baffles I34 or the gap between the fan-shaped baffles III39 and the fan-shaped baffles II38 falls into the conduit in a ring shape as the fan-shaped baffles III39, the fan-shaped baffles II38 and the fan-shaped baffles I34 rotate, so that the concrete in the conduit is spread more evenly and the generation of bubbles is reduced.
