[0029] The bottom of the base plate 1 is fixedly connected to a support foot 13, which is connected to the base plate 1 by welding.

[0030] The working principle of the sand and gravel separation device for recycled concrete in this embodiment is as follows:

[0031] Unseparated sand and gravel are poured into the discharge hood 8. The sand and gravel pass through the discharge hood 8 into the separation frame 5 and fall into the innermost arc-shaped screen ring 6. The stepper motor 11 is started, and the stepper motor 11 drives the separation frame 5 to rotate left and right. The sand and gravel inside are separated step by step through the arc-shaped screen rings 6 with different apertures. After separation, the stepper motor 11 is started again, and the stepper motor 11 drives the separation frame 5 to rotate through the rotating shaft 4. When the top of the separation frame 5 is vertical, the sand and gravel inside one of the arc-shaped screen rings 6 is poured out. After rotating in the opposite direction, the sand and gravel inside the other arc-shaped screen ring 6 is poured out. Finally, the door of the sealing cover 7 is opened to pour out the sand and gravel in the innermost arc-shaped screen ring 6. Because the top of the arc-shaped screen ring 6 is equipped with a blocking plate 12 on the left and right sides and the sealing cover 7, the large particles of stone inside the arc-shaped screen ring 6 can slide down through the stepper motor 11 driving the separation frame 5 to rotate.

[0032] Compared with the prior art, the present invention has the following advantages:

[0033] 1. After separation is completed, start the stepper motor 11. The stepper motor 11 drives the separation frame 5 to rotate through the rotating shaft 4. When the top of the separation frame 5 is vertical, the sand and gravel inside one of the arc-shaped screen rings 6 will be poured out. After rotating in the opposite direction, the sand and gravel inside the other arc-shaped screen ring 6 will be poured out. Finally, open the door of the sealing cover 7 to pour out the sand and gravel in the innermost arc-shaped screen ring 6. Because the top of the arc-shaped screen ring 6 is equipped with a blocking plate 12 and a sealing cover 7 on the left and right sides, the large particles of stone inside the arc-shaped screen ring 6 can slide down through the stepper motor 11 driving the separation frame 5 to rotate. They do not need to be removed manually, which consumes less manpower.

[0034] 2. Pour the unseparated sand and gravel into the feeding hood 8. The sand and gravel pass through the feeding hood 8 into the separating frame 5 and fall into the innermost arc-shaped screen ring 6. Start the stepper motor 11. The stepper motor 11 drives the separating frame 5 to rotate left and right. The sand and gravel inside are separated step by step through the arc-shaped screen rings 6 with different apertures. The motor 11 drives multiple sets of arc-shaped screen rings 6 to rotate for multi-stage separation, which makes it easy to separate the sand and gravel by utilizing the friction between the sand and gravel and the arc-shaped screen rings 6.
