During molding, the vibration force and amplitude of the inner mold are adjusted to compact the concrete with the best vibration force, thereby obtaining C50 high-strength pipe concrete, which significantly enhances the load resistance and impermeability of the pipeline compared to the centrifugal and suspension roller processes. At the same time, the concrete pipe steel mesh protective layer of this process is uniform, and there will be no centrifugal and suspension roller process steel mesh displacement, skipping, joint reinforcement, loose reinforcement and other phenomena, which ensures the service life of the pipe.

[0026] Please refer to Figure 1-4 The anti-condensation feeding device for drain pipe casting comprises a carrier frame 1, a rotary feeding barrel 2, a mold 3, a screw feeder 4 and an anti-condensation assembly 6. The carrier frame 1 is rotatably connected to the rotary feeding barrel 2, and a feeding pipe 10 is fixedly installed on the bottom surface of the rotary feeding barrel 2. The discharge end of the screw feeder 4 is located above the rotary feeding barrel 2. A driving motor 7 is fixedly installed on the top surface of the carrier frame 1, and a gear 8 is installed on the output end of the driving motor 7. A gear ring 9 is welded on the outer wall of the rotary feeding barrel 2, and the gear 8 is meshed with the gear ring 9.

[0027] In this embodiment: the anti-condensation component 6 is composed of a bracket 61, a stirring motor 62, a rotating column 63, an anti-condensation stirring rod 64, a scraper 65, a chamber 66, a guide rod 67, a limit block 68 and a spring 69. The bracket 61 is welded to the top surface of the carrier 1, and the stirring motor 62 is installed on the bracket 61.

A chamber 66 is opened inside the anti-condensation stirring rod 64, and the interior of the chamber 66 is slidably connected to the limit block 68. A guide rod 67 is welded to the surface of one side of the limit block 68, and one end of the guide rod 67 extends to the outside of the chamber 66 and is installed with a scraper 65. A spring 69 is sleeved on the outside of the guide rod 67 between the limit block 68 and the inner wall of the chamber 66.

[0028] Specifically, when in use, referring to a cement feeding device disclosed in Chinese Patent Publication No.: CN213797222U, the operator conveys the raw materials into the rotary feeding barrel 2 by the screw conveyor, and then starts the driving motor 7, and the gear 8 drives the gear ring 9 to move. At this time, the rotary feeding barrel 2 rotates, and the raw materials in the rotary feeding barrel 2 are added to the mold 3 along the feeding pipe 10. During the adding process, because the shape of the mold 3 is annular, and the movement path of the discharge end of the feeding pipe 10 is also annular, the feeding device can perform a continuous feeding of the raw materials in the mold 3. Uniform feeding reduces the step of using vibration to make the raw materials in the mold 3 uniform, reduces operation time, and improves production efficiency. The stirring motor 62 drives the anti-condensation stirring rod 64 to rotate, which can stir the materials inside the rotary feeding barrel 2 in all directions, thereby ensuring the quality of the concrete and preventing precipitation and solidification. The structure is simple and practical, and it is worthy of promotion. It should be noted that the anti-condensation principle of this article is the same as the anti-condensation principle of a concrete cart for preventing concrete from solidifying disclosed in Chinese Patent Publication No. CN213168150U.

[0029] In this embodiment: the feeding pipe 10 is arranged at an angle, and the discharge end of the feeding pipe 10 is located directly above the feed port of the mold 3 .

[0030] Specifically, the discharge end of the feeding pipe 10 can be made to move in a circular motion to feed the material evenly into the mold 3 .

[0031] In this embodiment, the surface of the scraper 65 is elastically fitted to the inner wall of the rotary feeding barrel 2 .

[0032] Specifically, the scraper 65 can always maintain a good elastic fit with the inner wall of the rotary feeding barrel 2. The scraper 65 rotates with the anti-condensation stirring rod 64, and can scrape off the material attached to the inner wall of the rotary feeding barrel 2 to prevent the material from solidifying on the inner wall of the rotary feeding barrel 2, thereby avoiding the problem of reduced internal space of the rotary feeding barrel 2.

[0033] In this embodiment: a control panel 5 is fixedly mounted on the surface of the carrier frame 1 , and the control panel 5 is electrically connected to the stirring motor 62 , the driving motor 7 and the screw feeder 4 through wires.

[0034] Specifically, it is a common circuit connection structure, which will not be described in detail here.

[0036] Specifically, the mixing effect and efficiency of materials are improved.

[0037] In this embodiment: the controller is an existing structure, and the control circuit can be implemented by simple programming by technicians in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection are not described in detail.

[0038] Working principle: When in use, refer to a cement feeding device disclosed in Chinese Patent Publication No.: CN213797222U. The operator transports the raw materials from the screw conveyor to the rotary feeding barrel 2, and then starts the drive motor 7. The gear 8 drives the gear ring 9 to move. At this time, the rotary feeding barrel 2 rotates, and the raw materials in the rotary feeding barrel 2 are added to the mold 3 along the feeding pipe 10. During the adding process, because the shape of the mold 3 is annular, and the movement path of the discharge end of the feeding pipe 10 is also annular, the feeding device can evenly add material to the mold 3, reducing the step of using vibration to make the raw materials in the mold 3 uniform, reducing the operation time, and improving production efficiency. The stirring motor 62 drives the anti-condensation stirring rod 64 rotates, and can stir the materials inside the rotary feeding barrel 2 in all directions, thereby ensuring the quality of the concrete, and will not produce precipitation and solidification. The structure is simple and practical, and it is worthy of promotion. It should be noted that the anti-condensation principle of this article is the same as the anti-condensation principle of a concrete cart to prevent concrete from solidifying disclosed in Chinese Patent Publication No.: CN213168150U. Secondly, the scraper 65 can always maintain a good elastic fit with the inner wall of the rotary feeding barrel 2. The scraper 65 rotates with the anti-condensation stirring rod 64, and can scrape off the materials attached to the inner wall of the rotary feeding barrel 2 to prevent the materials from solidifying on the inner wall of the rotary feeding barrel 2, thereby avoiding the problem of reduced internal space of the rotary feeding barrel 2.

[0039] It should be noted that the models and specifications of the stirring motor 62, the driving motor 7 and the screw feeder 4 need to be selected and determined according to the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The power supply and principle of the stirring motor 62, the driving motor 7 and the screw feeder 4 are clear to those skilled in the art and will not be described in detail here.
