[0031] The reinforcing mechanism is arranged on one side of the material distributing mechanism, and the reinforcing mechanism includes an auxiliary material hopper 12, a fixed frame 13, a second cylinder 14, a discharge pipe 15, a discharge tray 16 and a plurality of discharge heads 17 arranged on the discharge tray 16, the fixed frame 13 is located above the conveyor belt 3, the fixed frame 13 is fixed on one side of the bracket 4, the auxiliary material hopper 12 is arranged on the fixed frame 13, the second cylinder 14 is arranged vertically downward on the fixed frame 13, the discharge tray 16 is arranged horizontally below the second cylinder 14, the middle part of the upper end of the discharge tray 16 is connected to the gas rod of the second cylinder 14, one end of the discharge pipe 15 is connected to the auxiliary material hopper 12, and the other end of the discharge pipe 15 is connected to the discharge tray 16, each discharge head 17 is arranged on the lower end surface of the discharge tray 16, and the shape of the discharge head 17 is a quadrangular pyramid;

[0032] The four triangular sides of the material discharge head 17 are provided with through holes, and the through holes are connected with the material discharge pipe 15 through the inside of the material discharge tray 16;

[0033] The mold box 18 is arranged on the conveyor belt 3, and the upper end of the mold box 18 is open. A wire mesh 19 is provided at the bottom of the mold box 18, and the wire mesh 19 is parallel to the conveyor belt 3. An elastic component is also provided at the bottom of the mold box 18, and the elastic component is located below the wire mesh 19. The elastic component includes a support plate 20 and a plurality of reset units. The upper end surface of the support plate 20 is in contact with the wire mesh 19, and each reset unit is located below the support plate 20. The support unit includes a sleeve 21 and a support rod 22. The support rod 22 and the sleeve 21 are both vertically arranged. A spring 23 is provided in the sleeve 21, and the upper end of the support rod 22 extends into the sleeve 21. One end of the spring 23 is connected to one end of the support rod 22 extending into the sleeve 21, and the other end of the spring 23 is connected to the support plate 20.

[0034] Preferably, the spring 23 is in a compressed state, so that it can play a better supporting role. Under normal conditions, even if concrete is injected into the mold box 18, the support plate 20 cannot sink a large distance. Even if it sinks, it is within the error value range, thereby ensuring the accuracy of the precast plate.

[0035] Preferably, the grid of the wire mesh 19 is a square grid, the projection area of ​​the grid is larger than the projection area of ​​the blanking head 17 , and each blanking head 17 is located in the grid, mainly to prevent the grid of the wire mesh 19 from interfering with the descent of the blanking head 17 .

[0036] Preferably, the length of the feed head 17 is greater than the distance from the wire mesh 19 to the upper end of the mold box 18. This arrangement is mainly to ensure that when the lower end surface of the feed tray 16 abuts against the upper end of the mold box 18, the top end of the feed head 17 can push the support plate 20 down a certain distance.

[0037] Preferably, the projection area of ​​the discharge tray 16 is larger than the projection area of ​​the opening of the mold box 18. This arrangement is mainly to enable the discharge tray 16 to completely cover the top of the mold box 18 to reduce the overflow of concrete.

[0038] Preferably, the bracket 4 and the fixing frame 13 are both provided with infrared sensors 11, and the fixing frame 13 is also provided with a control box, and the control box is provided with a PLC, and the motor, the first cylinder 8, the second cylinder 14, and the two infrared sensors 11 are all electrically connected to the PLC.

[0039] In fact, a solenoid valve is also provided in the auxiliary material hopper 12, and the solenoid valve is also electrically connected to the PLC. Here, the first cylinder 8, the second cylinder 14 and the motor are controlled mainly through the cooperation of the PLC and the infrared sensor 11, thereby realizing automation.

[0040] During operation, coarse concrete is pre-injected into the material distribution hopper 5, and fine concrete, i.e., concrete with a high density and fine particle size, is injected into the auxiliary material hopper 12, and the fine concrete contains an anti-seepage agent. When the infrared sensor 11 located on the bracket 4 detects that the mold box 18 is conveyed by the conveyor belt 3, the PLC controls the first cylinder 8 to operate according to the pre-set process, and the gas rod of the first cylinder 8 contracts, so that the support rod 10 drives the cover plate 9 to operate, and the cover plate 9 opens, so that the coarse concrete in the discharge barrel 7 falls into the mold box 18. As the conveyor belt 3 drives the mold box 18 to move under the discharge barrel 7 for a period of time, the PLC controls the first cylinder 8 to operate to extend its gas rod, thereby Close the cover plate 9. At this time, the mold box 18 is just filled with rough concrete, but there are many pores in the concrete and the concrete is relatively loose. When the infrared sensor 11 located on the fixed frame 13 detects the mold box 18, the PLC controls the second cylinder 14 to start the action according to the preset time, so that when the mold box 18 is completely located directly under the unloading tray 16, the conveyor belt 3 is controlled to work, and the mold box 18 will stay under the unloading tray 16. Then the second cylinder 14 is controlled to act and the gas rod is extended so that the unloading tray 16 is pushed toward the mold box 18, and the unloading head 17 will penetrate into the concrete of the mold box 18 until the unloading head 17 passes through the mesh of the wire mesh 19 in the mold box 18. The tip of the material head 17 presses against the support plate 20, and the PLC controls the solenoid valve in the auxiliary hopper 12 to open. The fine concrete enters the material feeding plate 16 through the material feeding pipe 15, and then enters the material feeding head 17, thereby entering the concrete from the four side openings of the material feeding head 17. As the material feeding head 17 further pushes the support plate 20 downward, the concrete at the position of the wire mesh 19 will produce a small stratification phenomenon. Although the concrete will sink as a whole under the influence of its own gravity, the friction between the sand and gravel between the concrete is large, and the sinking speed is less than the speed at which the material feeding head 17 pushes the support plate 20 downward, that is, the descending speed of the support plate 20 is greater than the sinking speed of the concrete above the wire mesh 19. A stratification phenomenon occurs, and at this time, fine concrete is injected from the feed head 17, and the fine concrete will penetrate into the gaps between the coarse concrete. Then, when the feed head 17 moves upward, under the action of the spring 23, the support plate 20 moves upward and presses the concrete upward in the opposite direction. Under the upward pressure of the support plate 20 and the downward gravity of the concrete itself, when the second cylinder 14 drives the feed head 17 to move upward until the feed head 17 is completely separated from the mold box 18, the concrete will be compacted again. In this way, fine concrete is added from the middle of the concrete, and the penetration effect is better. It penetrates into each gap inside, thereby improving the overall density of the concrete, enhancing the strength of the precast panel, and improving the anti-seepage performance.

[0041] Compared with the prior art, the high-strength impermeable concrete prefabricated component manufacturing equipment injects coarse concrete into the mold box 18 through a distribution mechanism, and then injects fine concrete into the molded coarse concrete through a reinforcement mechanism, thereby improving the density and strength of the prefabricated board, and greatly improving the impermeability and firmness of the prefabricated board.

[0042] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
