[0020] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides a self-healing and enhanced green recycled concrete rapid prototyping device, including a base plate 1. A support bracket 2 is fixedly connected to the upper surface of the base plate 1. A motor 3 is fixedly connected to the outer wall of the support bracket 2. A through shaft 11 is connected to the output end of the outer wall of the motor 3. Turntables 4 are fixedly connected to both sides of the outer wall of the through shaft 11. A crank 5 is rotatably connected to the outer wall of the turntable 4. A crossbar 6 is rotatably connected to the outer wall of the crank 5. A fixed column 7 is rotatably connected to the inner wall of the crossbar 6. The middle of the inner wall of the crossbar 6 rotates. An H-shaped bracket 8 is connected, and a column 9 is rotatably connected to the outer wall of the H-shaped bracket 8. A holding plate 10 is fixedly connected to the outer wall of the column 9. A protective block 32 is slidably connected to the outer wall of the column 9. A protective component 12 is provided on the upper surface of the support bracket 2. The protective component 12 is used to assist the movement of the holding plate 10. A lower mold 13 is provided on the upper surface of the holding plate 10. An upper mold 14 is attached to the upper surface of the lower mold 13. A locking mechanism 15 is provided on the outer wall of the upper mold 14. A locking mechanism 15 is provided on the outer wall of the lower mold 13.

[0022] Specifically, the motor 3 drives the through shaft 11 to rotate, acting as a drive source. This, in turn, drives the turntables 4 on both sides to rotate synchronously, causing the crank 5 to rotate around the axis of the through shaft 11. The eccentric connection between the crank 5 and the turntables 4 causes the crossbar 6 to swing up and down rhythmically via the fixed column 7 as the turntables 4 rotate. The fixed column 7 supports the crossbar 6, preventing it from falling and restricting its position. This, in turn, causes the H-shaped bracket 8 to move rhythmically, lifting the column 9. The movement of the column 9, along with the movement of the protective block 32, restricts the direction of movement of the column 9, preventing the entire part from jamming due to displacement. The movement of the column 9 drives the holding plate 10 to move, which in turn drives the lower mold 13 and the upper mold 14 to move. The locking mechanism 15 ensures the stability of the connection between the lower mold 13 and the upper mold 14, thereby promoting the flow of slurry and filling all corners of the lower mold 13 and the upper mold 14, reducing the need for manual intervention, shortening the molding time, and meeting the needs of rapid production.

[0023] Please see the appendix Figure 1 and attached Figure 5 The protective component 12 includes a hollow column 1201. The outer wall of the hollow column 1201 is fixedly connected to the upper surface of the support bracket 2. A sliding column 1202 is slidably connected to the inner wall of the hollow column 1201. The outer wall of the sliding column 1202 is fixedly connected to the lower surface of the holding plate 10. A spring 1203 is fixedly connected to the lower surface of the holding plate 10. The outer wall of the spring 1203 is fixedly connected to the upper surface of the support bracket 2.

[0024] Specifically, when the column 9 causes the holding plate 10 to vibrate, it will simultaneously cause the sliding column 1202 to move on the outer wall of the hollow column 1201 and compress the spring 1203. The sliding column 1202 and the hollow column 1201 prevent the holding plate 10 from falling too far and hitting the support bracket 2, which would damage the holding plate 10. The spring 1203 provides linear upward power when the holding plate 10 is moved upward, reduces the friction between the crank 5 and the turntable 4, and improves the service life of the device.

[0025] Please see the appendix Figure 4 and attached Figure 8 The outer wall of the through shaft 11 is rotatably connected to the inner wall of the support bracket 2, the outer wall of the fixed column 7 is fixedly connected to the inner wall of the support bracket 2, and the outer wall of the protective block 32 is fixedly connected to the inner wall of the support bracket 2.

[0026] Specifically, the support bracket 2 supports the through shaft 11 to prevent it from falling and to limit its position. The support bracket 2 also supports and fixes the fixed column 7, which limits the position of the crossbar 6 and provides support force when the crossbar 6 rotates, ensuring that the crank 5 can pull the crossbar 6 to swing.

[0027] Please see the appendix Figure 6 The upper mold 14 is equipped with a heating wire 17 inside. A stop block 16 is fixedly connected to the outer wall of the heating wire 17. The outer wall of the stop block 16 is set on the inner wall of the upper mold 14. A control panel 33 is fixedly connected to the outer wall of the support bracket 2. The control panel 33 is electrically connected to the heating wire 17.

[0028] Specifically, the control panel 33 can control the start of each drive source and heat the heating wire 17, so that heat is generated inside the upper mold 14. The control panel 33 controls the temperature of the heating wire 17 to accelerate the solidification process of concrete and further improve the molding efficiency. The stop block 16 and the upper mold 14 support and limit the heating wire 17 to prevent the heating wire 17 from falling out of the upper mold 14.

[0029] Please see the appendix Figure 7 and attached Figure 8 A bevel gear 18 is fixedly connected to the middle of the outer wall of the through shaft 11. A bevel gear 19 is meshed with the tooth end of the bevel gear 18. A through shaft 20 is fixedly connected to the inner wall of the bevel gear 19. A helical gear 21 is fixedly connected to the outer wall of the through shaft 20. A connecting bracket 22 is rotatably connected to the outer wall of the through shaft 20. A helical gear 23 is meshed with the tooth end of the helical gear 21. A rotating shaft 24 is fixedly connected to the inner wall of the helical gear 23. A stirring rod 25 is fixedly connected to the outer wall of the rotating shaft 24. A repair agent storage tank 26 is rotatably connected to the outer wall of the rotating shaft 24.

[0030] Specifically, when motor 3 drives the through shaft 11 to rotate, it will synchronously drive water pipe 28 to rotate. At this time, water pipe 28 acts as a transmission structure, driving bevel gear 19 to rotate through bevel gear 18, which in turn drives the through shaft 20 to rotate synchronously. The connecting bracket 22 supports and limits the through shaft 20. Through the meshing of helical gear 11 and helical gear 23, the rotating shaft 24 is synchronously driven to rotate inside the repair agent storage tank 26, thereby driving the stirring rod 25 to rotate with the rotating shaft 24, stirring the repair agent inside the repair agent storage tank 26, preventing the substances inside the repair agent from settling. This achieves the effect of simultaneously vibrating the slurry inside the lower mold 13 and the upper mold 14, and also simultaneously stirring the repair agent inside the repair agent storage tank 26, maintaining microbial activity and improving repair efficiency.

[0031] Please see the appendix Figure 7 and attached Figure 8 The outer wall of the connecting bracket 22 is fixedly connected to the outer wall of the supporting bracket 2, and the outer wall of the repair agent storage tank 26 is fixedly connected to the upper surface of the connecting bracket 22.

[0032] Specifically, by connecting the connecting bracket 22 to the supporting bracket 2, the position of the through shaft 20 is limited while preventing it from falling, thus preventing it from moving due to the force of the bevel gear 19. The connecting bracket 22 also supports the repair agent storage tank 26.

[0033] Please see the appendix Figure 7 and attached Figure 8 A water pump 27 is installed on the upper surface of the repair agent storage tank 26. A water pipe 28 is fixedly connected to the output end of the water pump 27. A high-pressure atomizing nozzle 29 is fixedly connected to the outer wall of the water pipe 28.

[0034] Specifically, the repair agent is drawn from the repair agent storage tank 26 by the water pump 27 as the driving source, and transported to the high-pressure atomizing nozzle 29 through the water pipe 28. The repair agent is then atomized by the high-pressure atomizing nozzle 29 and sprayed onto the surface of the concrete inside the vibrating lower mold 13 and upper mold 14. While the slurry inside the lower mold 13 and upper mold 14 is vibrating, the repair agent is also added to the slurry, achieving a uniform distribution of the self-healing function and improving the repair efficiency.

[0035] Please see the appendix Figure 3 Appendix Figure 7 and attached Figure 8 The outer wall of the high-pressure atomizing nozzle 29 is set on the inner wall of the upper mold 14, and the high-pressure atomizing nozzle 29 is located in the middle of the upper mold 14.

[0036] Specifically, by setting the high-pressure atomizing nozzle 29 in the middle of the upper mold 14, it is ensured that when the high-pressure atomizing nozzle 29 sprays the repair agent, it can spray to all positions inside the lower mold 13 and the upper mold 14, thereby improving the uniformity of the repair agent in the slurry.

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 9 A concrete pump 30 is provided on the upper surface of the substrate 1. The output end of the concrete pump 30 is fixedly connected to a conveying pipe 31. The outer wall of the conveying pipe 31 is provided on the inner wall of the upper mold 14.

[0038] Specifically, by setting up a concrete delivery pump 30, the slurry can be directly delivered through the delivery pipe 31 to the cavity formed by the lower mold 13 and the upper mold 14, reducing the step of manual addition and improving work efficiency.

[0039] Please see the appendix Figure 10 A method of using a self-healing reinforced green recycled concrete rapid prototyping device, for use with any one of claims 1-9, includes the following steps: S1: The upper mold 14 and the lower mold 13 are fixed by the locking mechanism 15; S2: Start the concrete delivery pump 30 to inject the recycled concrete slurry into the cavity formed by the upper mold 14 and the lower mold 13; S3: Start motor 3 to compact the concrete slurry; S4: Start the water pump 27 and spray the repair agent evenly onto the concrete surface through the high-pressure atomizing nozzle 29; S5: After the concrete has initially set, loosen the locking mechanism 15 and remove the formed concrete.

[0040] Specifically, in step S1, the upper mold 14 and the lower mold 13 are fixed by the locking mechanism 15 to prevent the upper mold 14 and the lower mold 13 from shifting or misaligning during vibration, thus ensuring the geometric accuracy of the formed structure. In step S2, the concrete pump 30 rapidly and continuously injects the slurry into the cavity formed by the upper mold 14 and the lower mold 13 through the delivery pipe 31. Compared with the traditional manual pouring or gravity flow method, this greatly shortens the filling time and improves work efficiency. In step S3, the start motor 3 drives the through shaft 11 and the connected parts to run, vibrating the concrete slurry in the cavity formed by the upper mold 14 and the lower mold 13. This reduces the need for manual intervention, shortens the molding time, and meets the needs of rapid production. At the same time, the bevel gear 18 drives the repair agent in the repair agent storage tank 26 to stir the repair agent, maintain the activity of microorganisms, and improve the repair efficiency. In step S4, the repair agent is sprayed into the vibrating concrete slurry to ensure that the repair agent is fully and evenly mixed inside the concrete slurry, thereby achieving a uniform distribution of the self-healing function and improving the repair efficiency. In step S5, by opening the locking mechanism 15, the lower mold 13 and the upper mold 14 can be separated, making it convenient to remove the internally formed concrete.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
