When the reciprocating scraper moves left and right to promote the screening efficiency, the through hole corresponds to the through hole and passes through the inside of the through hole, so as to achieve the effect of self-dredging, avoid the clogging of the screening plate, further ensure the screening efficiency, and improve the convenience of use of the recycling device; S2: When the dredging rod is lifted and lowered along the through hole on the screening plate, the upper end of the dredging rod drives the auxiliary plate to move up and down, and the contact plate is pushed up by the adjustment plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. When the reciprocating scraper moves left and right to promote the screening efficiency, as the reciprocating scraper moves, the dredging rod inside it, under the action of the reset spring, corresponds to the through hole and passes through the inside of the through hole. On the contrary, when the reciprocating scraper continues to move, the dredging rod can automatically squeeze the reset spring upward through the curvature of the bottom and the curvature of the upper end of the through hole to achieve the reset and contraction of the dredging rod, thereby achieving the effect of self-dredging, avoiding the blockage of the screening plate, further ensuring the screening efficiency, and improving the convenience of using the recycling device; Furthermore, when in use, an appropriate amount of concrete residue or mixer truck cleaning material is added through the feed port at the upper end of the shell, so that the concrete residue and the mixer truck cleaning material fall on the screening plate.

[0019] 2. When the dredging rod is lifted and lowered along the through hole on the screening plate, the upper end of the dredging rod drives the auxiliary plate to move up and down. As the auxiliary plate moves up and down, the adjusting plate can be driven to perform reciprocating height adjustment. As the adjusting plate reciprocates in height, the connecting pipe and the water outlet can be adjusted to reciprocate rotation, thereby increasing the range of water spray cleaning and further improving the efficiency of recycling concrete residues and materials cleaned by mixer trucks; 3.

[0035] When the dredging rod 16 is lifted and lowered along the through hole 15 on the screening plate 14, the upper end of the dredging rod 16 drives the auxiliary plate 18 to move up and down. As the auxiliary plate 18 moves up and down, the adjusting plate 19 can be driven to perform reciprocating height adjustment. As the adjusting plate 19 reciprocates in height, the adjusting plate 19 slides along the inside of the slotted plate 20 while squeezing the contact plate 21 upward. The contact plate 21 is lifted up by the adjusting plate 19. At this time, the contact plate 21 drives the connecting pipe 8 and the water outlet 9 to rotate.

8. The device for recycling residual concrete materials from a mixing station and materials washed from a mixing truck according to claim 1, characterized in that: The vibration blocking prevention mechanism further comprises a partition (23), and the outer side of the partition (23) is fixedly mounted on the inner wall of the shell (1), and an elastic airbag (24) is arranged on the inner side of the partition (23), and the outer side of the elastic airbag (24) is fixedly mounted on the inner wall of the shell (1), and an expansion airbag (26) is fixedly mounted on the outer side of the shell (1), and the expansion airbag (26) is located inside the knocking chamber (27), and the expansion airbag (26) and the elastic airbag (24) are connected through an air guide tube (25).

9. The device for recycling residual concrete materials from a mixing station and materials washed from a mixing truck according to claim 8, characterized in that: The upper end of the knocking chamber (27) is provided with a positioning rod (30), and a push plate (29) is installed through the surface of the positioning rod (30), and the inner side of the push plate (29) is fixedly installed on the outer side of the expansion airbag (26), and the push plate (29) corresponds to the upper end of the knocking rod (28), and the lower end of the knocking rod (28) corresponds to the outer side of the shell (1) and the screening plate (14), and a rebound plate (32) is installed through the surface of the positioning rod (30), and a vibration spring (31) is provided between the rebound plate (32) and the knocking chamber (27), and the rebound plate (32) corresponds to the upper end of the knocking rod (28).

10. The method for recycling the residual concrete material of a mixing station and the material recycling device for cleaning a mixing truck is characterized in that: The specific steps include: S1: When in use, an appropriate amount of concrete residue or material from a mixer truck cleaning is added through the feed port (5) at the upper end of the housing (1), so that the concrete residue and material from a mixer truck cleaning fall onto the screening plate (14). When the reciprocating scraper (12) moves left and right to promote screening efficiency, the through hole (15) corresponds to the through hole (15) and passes through the inside of the through hole (15), thereby achieving a self-draining effect and avoiding clogging of the screening plate (14), thereby further ensuring screening efficiency and improving the convenience of use of the recycling device; S2: When the dredging rod (16) is raised and lowered along the through hole (15) on the screening plate (14), the upper end of the dredging rod (16) drives the auxiliary plate (18) to move up and down, and the contact plate (21) is pushed up by the adjustment plate (19). At this time, the contact plate (21) drives the connecting pipe (8) and the water outlet (9) to rotate. At this time, the reciprocating rotation adjustment of the connecting pipe (8) and the water outlet (9) can be achieved, thereby increasing the range of water spray cleaning and further improving the efficiency of recycling concrete residues and materials cleaned by the mixer truck; S3: When the reciprocating scraper (12) moves back and forth left and right, when the reciprocating scraper (12) moves to the rightmost end or the leftmost end, the elastic air bag (24) inside the partition (23) is squeezed, and the upper end of the knocking rod (28) is squeezed and the knocking rod (28) rotates. The knocking rod (28) rotates and knocks the corresponding position of the screening plate (14) on the outer wall of the shell (1), thereby achieving a knocking vibration effect, and further avoiding clogging of the screening plate (14).
