[0043] The separation tank 1 is provided with a driving mechanism, and the driving mechanism comprises a first one-way bearing 30. The side wall of the separation tank 1 is fixedly connected with a U-shaped plate 25. The upper end of the U-shaped plate 25 is fixedly connected with a motor 26.

[0048] After the fourth rod 29 drives the storage tank 4 to rotate half a circle, the filter plate 36 opposite to the two loading holes 6 at this time is changed, which indicates that there is more concrete residue on the inner wall of the loading hole 6 used at the beginning, and during the rotation of the storage tank 4 half a circle, the third gear 51 rotates an odd multiple of half a circle on the side wall of the tooth ring 50, so that the positions of the two loading holes 6 can be changed after the rotation of the storage tank 4 half a circle, that is, the loading hole 6 originally located in the storage tank 4 is rotated to below the fixed plate 7, and the loading hole 6 originally located below the fixed plate 7 is rotated into the storage tank 4.

[0057] And in the process of the storage tank 4 rotating a half circle, at this time the third gear 51 rotates an odd multiple of a half circle in the side wall of the gear ring 50, so that after the storage tank 4 rotates a half circle, the positions of the two loading holes 6 can be exchanged, that is, the loading hole 6 originally located in the storage tank 4 rotates to below the fixed plate 7, and the loading hole 6 originally located below the fixed plate 7 rotates into the storage tank 4, so that the remaining concrete in the storage tank 4 can enter the separation tank 1 through the clean loading hole 6 in the inner wall;

[0058] Then when the driving motor 26 rotates clockwise (as shown in Figure 3 ), at this time the third rod 28 drives the outer ring of the second one-way bearing 31 to rotate clockwise through the first wheel 32, the synchronous belt and the second wheel 33, at this time the outer ring of the second one-way bearing 31 drives the inner ring to rotate, and drives the reciprocating lead screw 11 to rotate clockwise (as shown in Figure 3 ), at this time the first plate 12 slides up and down on the side wall of the reciprocating lead screw 11, and then the first plate 12 drives the first disc 14 to move up and down through the two connecting rods 13, the first disc 14 drives the second disc 52 to move up and down through the second rod 16, and the plurality of triangular plates 18 can be attached to the inner wall of the loading hole 6 at this position under the action of the plurality of springs 19, and at the same time, the threaded cylinder 20 moves up and down on the side wall of the Laver rod 24, at this time the threaded cylinder 20 can continuously rotate forward and backward, and drives the second rod 16 to rotate through the first gear 21 and the second gear 22, and drives the second disc 52 to rotate, so that the plurality of triangular plates 18 move in a mode of moving up and down and rotating at the same time, and the cleaning of the remaining concrete in the loading hole 6 is accelerated, and the dredging mechanism is not located in the loading hole 6, avoiding the existing technology that the through plug plate is located in the feeding frame, so that in the process of conveying the remaining concrete, the through plug plate blocks the flow of part of the remaining concrete, reducing the unloading speed of the remaining concrete, and at the same time, in the cleaning process, the conveying of the remaining concrete in the other loading hole 6 is not affected, avoiding the existing technology that the remaining concrete cannot be conveyed when cleaning the remaining concrete, and the efficiency of separating sand and stone in the remaining concrete is reduced again;
