Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-3 This utility model provides an embodiment of a precast concrete pile cap casting device, comprising a casting truck 1, a material box 2 inside the truck body for storing raw materials or premixed concrete, a feeding hopper 4 fixedly connected inside the material box 2 for feeding concrete raw materials, a mixing mechanism inside the material box 2 for fully mixing the concrete raw materials to prevent segregation and sedimentation, thereby ensuring casting quality, a feeding pipe 10 at the bottom of the material box 2, a feeding mechanism inside the feeding pipe 10, a discharge pipe 16 fixedly connected inside the feeding pipe 10, a discharge pipe 20 at the bottom of the discharge pipe 16, and the discharge pipe 20 ultimately discharges the concrete to the top of the pile cap mold, a quick-release mechanism between the discharge pipe 20 and the discharge pipe 16 for quick separation of the pipes without tools, significantly improving equipment maintenance efficiency; the mixing mechanism includes a motor 5, the side wall of the motor 5 fixedly connected to the side wall of the material box 2, and a rotating shaft 6 fixedly connected to one output end of the motor 5, the rotating shaft 6 being rotatably connected to the material box 2. Inside the container 2, a mixing blade 7 is fixedly connected to the side wall of the rotating shaft 6, which can perform three-dimensional mixing of concrete and effectively improve the uniformity of mixing. A connecting rod 8 is fixedly connected to the side wall of the container 2, and a scraper 9 is fixedly connected to the side wall of the connecting rod 8. The side wall of the scraper 9 is in contact with the inner wall of the container 2, which can scrape off the residual concrete on the inner wall of the container 2 to prevent it from sticking to the wall and improve the discharge rate. A connecting pipe 11 is fixedly connected between the container 2 and the feeding pipe 10, and the container 2, the connecting pipe 11 and the feeding pipe 10 are connected. The feeding mechanism includes a winch. The screw conveyor blade 12, with its spiral structure design, can achieve a continuous, uniform, and efficient feeding process, avoiding pipe blockage. The screw conveyor blade 12 is rotatably connected inside the feeding pipe 10. The outer wall of the screw conveyor blade 12 is in contact with the inner wall of the feeding pipe 10. One end of the screw conveyor blade 12 passes through the side wall of the feeding pipe 10 and is fixedly connected to a pulley 13. The other output end of the motor 5 is fixedly connected to a pulley 2 14. A belt 15 is provided between pulley 13 and pulley 2 14 to realize the linkage control of mixing and feeding.

[0037] Reference Figure 4The quick-release mechanism includes a first fixing ring 17 and a second fixing ring 21. The side wall of the first fixing ring 17 is fixedly connected to the side wall of the discharge pipe 16. The inner wall of the second fixing ring 21 is fixedly connected to the discharge pipe 20, which is used to smoothly discharge materials and ensure the sealing and continuity of the conveying process. The side wall of the first fixing ring 17 is fixedly connected to a claw 18 and a limit ring 19. The side wall of the second fixing ring 21 is fixedly connected to a limit ring 22 and a claw 23. The first fixing ring 17 and the second fixing ring 21 fit together, ensuring a tight and reliable connection during installation. The first claw 18 and the first limiting ring 19 are staggered, and the second limiting ring 22 and the second claw 23 are staggered. The staggered arrangement of the claws and the limiting rings gives the structure a self-locking function. The first claw 18 and the second limiting ring 22 are engaged, and the second claw 23 and the first limiting ring 19 are engaged, thereby effectively preventing rotation or axial displacement and further enhancing the connection stability. The two-way interlocking enhances the reliability of the overall connection and facilitates quick manual disassembly and assembly, improving on-site operation efficiency. The side wall of the material box 2 is fixedly connected to the fixing block 3, which is fixedly connected to the inside of the pouring vehicle 1. The feeding pipe 10 is fixedly connected to the inside of the pouring vehicle 1.

[0038] Working principle: When the equipment is in use, the discharge pipe 20 is moved to the top of the pile cap mold. Then, the concrete raw material is fed into the material box 2 through the feeding hopper 4. Then, the motor 5 is started, which drives the pulley 14 and the shaft 6 to rotate simultaneously. While the shaft 6 is rotating, it also drives the mixing blade 7 and the scraper 9 to move, mixing the raw material and cleaning the inner wall of the material box 2 to avoid raw material residue. During mixing, the raw material will fall into the feeding pipe 10 through the connecting pipe 11. When the pulley 14 rotates, it will drive the pulley 14 under the action of the belt 15. 3. Rotation causes the auger conveyor blade 12 to rotate, gradually conveying the raw material in the feed pipe 10 forward, allowing it to fall into the interior of the pile cap mold through the discharge pipe 16. After long-term use of the equipment, when it is necessary to disassemble and clean the discharge pipe 20, the discharge pipe 20 can be rotated to drive the limit ring 22 and the claw 23 to move synchronously. When the claw 23 moves between the claw 18 and the limit ring 19, the claw 18 is just located between the limit ring 22 and the claw 23. At this time, the discharge pipe 16 and the discharge pipe 20 are no longer restricted, and the discharge pipe 20 can be disassembled for cleaning.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
