[0014] like Figures 1-2As shown, the concrete mixing and feeding device for pipe piles of this utility model includes a support base 8 for placing a pipe pile mold 9. A base 1 is provided on one side of the support base 8. A slide block 2 is slidably disposed on the base 1 along the length direction of the pipe pile mold 9. The lower part of the slide block 2 is slidably engaged with the base 1 through a slide rail 23. A lead screw 22 is threadedly installed in the middle of the slide block 2. Both ends of the lead screw 22 are connected to the base 1 through bearing seats 24. One end of the lead screw 22 passes through the bearing seat 24 and is connected to a motor 25. A hopper 3 is installed on the upper part of the slide block 2. A positioning groove 21 is machined on the upper part of the slide block 2. The positioning groove 21 is shaped like a... The hopper 3 is arc-shaped, with its lower part extending into the positioning groove 21. The upper part of the hopper 3 is open. The side of the hopper 3 facing the support base 8 is hinged to the slide 2 via a pin 7. The other side of the hopper 3 is connected to the slide 2 via a cylinder 6. The two ends of the cylinder 6 are respectively hinged to the hopper 3 and the slide 2. A rotating shaft 4 is installed inside the hopper 3 along the front-back direction. Stirring blades 5 are evenly installed on the outer circumference of the rotating shaft 4. The two ends of the rotating shaft 4 pass through the hopper 3 and are connected to the bearing seat I10. The bearing seat I10 is fixed to the outer wall of the hopper 3. One end of the rotating shaft 4 is connected to the motor I11, which is installed at the end of the bearing seat I10.
[0015] The device is directly installed on one side of the support base used to place the pipe pile mold. After the raw materials are poured into the hopper, they are mixed by the mixing blades to form concrete. The concrete is then poured into the pipe pile mold, which facilitates the subsequent centrifugal molding process, saves concrete transportation steps, and avoids phenomena such as stratification and solidification of concrete during transportation. The device has a simple structure. The hopper is flipped by the cylinder to add material, and the screw rotation drives the slide and hopper to move at a uniform speed to achieve uniform distribution of concrete.
[0016] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;
[0017] During operation, the pipe pile mold is positioned on the support base. Concrete raw materials are poured into the hopper according to the ratio. Motor I starts working and drives the rotating shaft to rotate. As the mixing blade rotates with the shaft, it evenly mixes the concrete raw materials to form concrete. Then, motor I stops rotating. After the motor starts working again, it drives the lead screw to rotate. The rotational motion of the lead screw is converted into the translational motion of the slide. The slide moves the hopper along the length of the pipe pile mold. At the same time, the cylinder works. The cylinder rod lifts the left side of the hopper upward. The hopper flips around the pin shaft, thereby evenly pouring the concrete in the hopper into the pipe pile mold.
