The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified. Example

[0018] like Figure 1-3 As shown, the utility model provides a solid recycled concrete precast pile device, including a plurality of pile molds 10, and also includes a device warehouse 1, the top of the device warehouse 1 is provided with a plurality of piston bottom plates 7 which can be synchronously lifted and lowered and correspond to the number of the plurality of pile molds 10, the outer diameter of the piston bottom plate 7 is consistent with the inner diameter of the pile mold 10, the device warehouse 1 is provided with a plurality of threaded columns 6 respectively connected with the piston bottom plates 7, the device warehouse 1 is also provided with a worm gear 3, when the worm gear 3 rotates, the plurality of threaded columns 6 can be indirectly driven to rotate, and the plurality of piston bottom plates 7 can be synchronously lifted and lowered in the pile mold 10, and the lowest height of the top of the plurality of piston bottom plates 7 is higher than the device warehouse 1.

[0019] In this embodiment, specifically, the pile mold 10 includes two mirror-imaged rectangular half molds 11, the two half molds 11 relatively form a rectangular cavity, and the bottom of the two half molds 11 of the pile mold 10 are provided with mounting holes 13, and the pile mold 10 can be fixed to the top of the device bin 1 by bolts and the mounting holes 13.

[0020] In this embodiment, specifically, the contact surfaces of the two half-molds 11 of the pile mold 10 are provided with sealing strips 12, and the two half-molds 11 of the pile mold 10 are provided with a plurality of connecting blocks 14 on the outside, and the two half-molds 11 can make the connecting blocks 14 correspond to each other after being aligned, and are connected by bolts and nuts;

[0021] The sealing strip 12 can be used to seal the two half molds 11 of the pile mold 10 to prevent leakage of unformed concrete inside, and the piston bottom plate 7 can also seal the bottom opening of the pile mold 10.

[0022] In this embodiment, specifically, the worm wheel 3 bearing is connected to both sides of the device bin 1 and is horizontally arranged inside the device bin 1. The inner bottom bearing of the device bin 1 is connected to a plurality of horizontally arranged worm wheels 3. The plurality of worm wheels 3 are meshed with the worm 4, and vertical threaded cylinders 5 are respectively fixed on the top surface. The plurality of threaded cylinders 5 are respectively threadedly connected to a plurality of threaded columns 6. The outside of the device bin 1 is fixed with a motor 2 which is transmission-connected to the worm 4.

[0023] In this embodiment, specifically, the top of the device bin 1 is provided with a plurality of telescopic openings 15 that match the piston bottom plate 7, and the inside of the device bin 1 is fixed with a plurality of support frames 8 located below the telescopic openings 15, and the top end of the threaded tube 5 matches and penetrates the support frame 8;

[0024] Among them, the support frame 8 is used to support the upper end of the threaded tube 5 and to limit the guide rod 9. When the guide rod 9 is limited, it can only be lifted and lowered. When the threaded tube 5 rotates, it will not drive the threaded column 6 to rotate, so that the lifting of the threaded column 6 drives the piston base plate 7 to lift and lower.

[0025] In this embodiment, specifically, the piston bottom plate 7 is embedded in the telescopic opening 15, and a mirror image guide rod 9 is fixed on the bottom surface, and the guide rod 9 and the support frame 8 are limitedly penetrated.

The motor 2 drives the worm 4 to rotate, and the worm 4 drives several worm wheels 3 to rotate, and the worm wheel 3 drives the threaded barrel 5 to rotate. Since the threaded column 6 is connected to the piston rod, the piston rod is connected to the guide rod 9, and the guide rod 9 and the support frame 8 are limited and penetrated, the rotation of the threaded barrel 5 will cause the threaded column 6 and the piston bottom plate 7 to move up, so as to synchronously adjust the position of the piston bottom plate 7 in the pile mold 10, and finally pour concrete or other steel bars in the pile mold 10.
