The lower end of the driving sleeve is plugged with a driving rod 711. The lower end of the driving rod 711 is connected to a scraper 705 for cleaning the surface of the steel template 4. Figure 5 As shown, a slag outlet 106 is provided at the bottom of the cleaning box 1 , and a slag receiving box 5 connected to the cleaning box 1 is provided at the lower end of the slag outlet 106 .

[0036] like Figure 6As shown, a slag drop hole is provided on the surface of the tray 2, a guide rod 202 is provided at the upper end of the tray 2, and the guide rod 202 is arranged along the length direction of the tray 2, guide rails 203 are provided at both ends of the tray 2, and sliders 204 are provided at both ends of the guide rod 202 to cooperate with the guide rails 203, a guide hole 207 is provided in the middle of the tray 2, and an ear plate 208 is provided at the lower end of the guide rod 202 to cooperate with the guide hole 207, and a first hydraulic cylinder 201 connected to the ear plate 208 is provided at the lower end of the tray 2. The position of the guide rod 202 is adjusted by the first hydraulic cylinder 201 to adapt to pallets 2 of different widths.

[0037] The two ends of the driving belt 3 are connected to the bottom of the cleaning box 1 through a bracket, as shown in FIG. Figure 7 As shown, a second motor 302 for driving the driving belt 3 to rotate is provided on the support 303, and a push rod 301 for pushing the steel template 4 is provided on the side wall of the driven belt, and the number of the push rods 301 is two.

[0038] A pull rod 205 for pushing the steel template 4 is provided at the top of the front end of the guide rod 202, and a cylinder 206 connected to the pull rod 205 is provided on the side wall of the guide rod 202. The cylinder 206 drives the pull rod 205 to slide along the upper end of the guide rod 202, and the pull rod 205 pushes the rear end of the steel template 4, pushing the steel template 4 inward, so that the push rod 301 can move to the rear of the steel template 4, thereby pushing the steel template 4.

[0039] like Figure 8 、 Figure 9 As shown, the drive sleeve includes an upper drive sleeve 708 and a lower drive sleeve 710 that are plugged in. A second hydraulic rod connected to the lower drive sleeve 710 is provided in the upper drive sleeve 708. The upper drive sleeve 708 is connected to the turntable 701. A drive rod 711 connected to the scraper 705 is plugged in the bottom of the lower drive sleeve 710. A spring 712 is connected between the lower drive sleeve 710 and the scraper 705. The upper end of the scraper 705 is connected to a photoelectric sensor 714. The photoelectric sensor 714 adopts a U-shaped beam switch. A detection piece 713 cooperating with the photoelectric sensor 714 is provided on the side wall of the lower drive sleeve 710.

[0040] Before use, the spring 712 extends, the driving rod 711 moves downward, the limit block 707 is located at the lower end of the limit hole 706, and the second hydraulic cylinder 709 pulls up the lower driving sleeve 710 so that the scraper 705 is higher than the steel template 4. When the steel template 4 moves below the scraper 705, the second hydraulic cylinder 709 extends to drive the scraper 705 to move downward. After the scraper 705 contacts the upper end of the steel template 4, the second hydraulic cylinder 709 continues to extend. When the photoelectric sensor 714 detects the detection piece 713, the second hydraulic cylinder 709 stops. At this time, the upper end of the driving rod 711 contacts the upper end of the lower driving sleeve 710, that is, the scraper 705 will not jump on the surface of the steel template 4. Then the first motor 105 drives the scraper 705 to rotate to scrape off the concrete residue on the surface of the steel template 4.

[0041] In order to improve the rotation stability of the scraper 705, a support arm 702 is connected to the side wall of the upper drive sleeve 708, the lower end of the support arm 702 is connected to a guide cylinder 703, and the upper end of the scraper 705 is connected to a telescopic rod 704 that cooperates with the guide cylinder 703.

[0042] In order to ensure the reliability of the fit between the driving rod 711 and the lower driving sleeve 710 , a limiting hole 706 is provided on the side wall of the lower driving sleeve 710 , and a limiting block 707 that fits with the limiting hole 706 is provided on the side wall of the driving rod 711 .

[0043] like Figure 10 As shown, a parallel lead screw 503 and a guide column 504 are provided in the slag box 5, a third motor 501 connected to the lead screw 503 is provided on the side wall of the slag box 5, a scraper 505 is provided in the slag box 5, the scraper 505 cooperates with the lead screw 503 through a nut sleeve, and cooperates with the guide column 504 through a guide sleeve, the lower end of the scraper 505 contacts the bottom of the slag box 5, and a discharge port 502 is provided at one end of the slag box 5, and the concrete residue can be pushed into the discharge port 502 through the scraper 505.

[0044] A water pump 102 is provided at the upper end of the cleaning box 1, the water inlet of the water pump 102 is connected to the water suction pipe 101, and the water outlet of the water pump 102 is connected to the water supply pipe 103. The water supply pipe 103 is arranged on the upper inner wall of the cleaning box 1, and a nozzle 104 is provided on the side wall of the water supply pipe 103. During the slag cleaning process, water is sprayed onto the surface of the steel formwork 4. During the rotation process, the scraper 705 can scrape off the concrete residue from the surface of the steel formwork 4 with the help of water flow.

[0045] The rear end of the cleaning box 1 is connected to a supporting platform 107, and a blower 6 is provided above the rear end outlet of the cleaning box 1. The air outlet of the blower 6 is connected to a long air outlet nozzle 601. Before the steel template 4 comes out of the cleaning box 1, the water on the surface is blown away by blowing air, thereby accelerating the drying speed and facilitating transportation.

[0046] When in use, first adjust the distance between the two guide rods 202 according to the width of the steel template 4 so that the two sides of the steel template 4 just contact the side walls of the guide rods 202; place the steel template 4 between the two guide rods 202, start the cylinder 206, and the pull rod 205 pushes the steel template 4 inward and resets it. Then the scraper 705 moves downward and contacts the surface of the steel template 4. When the photoelectric sensor 714 detects the detection piece 713, the water pump 102 starts to spray water to the steel template 4, and the scraper 705 starts to rotate. At the same time, the driving belt 3 rotates slowly, and the push rod 301 rotates from the bottom to the top of the driving belt 3, and then presses against the rear end of the steel template 4, pushing the steel template 4 forward slowly. During the movement, the scraper 705 scrapes the residue on the surface of the steel template 4. In addition, when the scraper 705 starts running, the blower 6 is also started. When the steel template 4 comes out of the cleaning box 1, it is blown and dried, and finally pushed onto the supporting platform 107 by the push rod 301. After cleaning, the scraper 705 stops and rises, and the driving belt 3 stops. The cleaned residue and water flow into the slag receiving box 5 through the slag drop port 106 for collection.

[0047] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
