The method of using the recycled concrete production device according to claim 5, characterized in that: Includes the following steps: (a) The waste concrete blocks are fed into the upper box (202) through the feeding pipe (1), and then the first motor (309) is started. The first motor (309) drives the crushing component to crush the waste concrete blocks in the upper box (202) through the reciprocating motion component. (ii) When the first motor (309) starts, it drives the moving frame (307) to slide along the side of the upper box (202) via the drive shaft (312). Then the moving frame (307) drives the extraction component to move via the drive plate (305). The dust generated during the crushing of waste concrete in the upper box (202) is sent into the collection box (301) through the first round pipe (302) by the extraction component. (iii) After the crushing process is completed, the second motor (413) starts and drives the second connecting rod (412) to rotate. The second connecting rod (412) drives the protective shell (403) to rise, and the crushed waste concrete falls into the filter screen (415) through the upper box (202). At the same time as the protective shell (403) rises, the rotating door (406) rotates and the crushed waste concrete powder falls into the processing box (401) through the upper surface of the rotating door (406). (iv) When the second connecting rod (412) rotates, it pushes the intermediate shaft (418) to move through the first connecting rod (409). The intermediate shaft (418) drives the feeding assembly to move, and the feeding assembly feeds the processing material in the liquid tank (421) into the processing box (401). At the same time, the third motor (422) starts, and the third motor (422) drives the stirring fan blade (423) to stir the material in the processing box (401). (v) When the first link (409) moves, it drives the air blowing assembly through the side shaft (417). The air blowing assembly sends air into the upper box (202) through the air delivery rod (501), thereby sending the crushed waste concrete powder into the square hole (210) more quickly and avoiding powder residue.
