First, place the mold (12) in the triangle plate (2) and the connecting plate (21), selectively install the nut (22) and the screw (23) according to the height of the mold (12), and pull the pin (74) to make the pin The column (74) is separated from the current positioning hole (76), the scraper (71) is moved up and down until it is equal to the height of the mold (12), the column (74) is loosened, and the second spring (75) drives the pin (74) Insert into the corresponding positioning hole (76), pour the concrete into the barrel (32) through the feeding box (33), and connect the device to the power supply; S2. Next, start the first motor (13), the first motor (13) drives the roller shaft (17) to rotate, which can drive the conveyor belt (16) to rotate, and the mold (12) can be moved by the baffle plate (18) on the conveyor belt (16). ) are sent out in turn, start the second motor (61), the second motor (61) drives the rotating shaft (64) to rotate through the synchronous wheel (62) and the synchronous belt (63), and the rotating shaft (64) drives the stirring spoon (65) and the scraper (66) rotates to agitate the concrete in the barrel (32) and scrape off the concrete adhered to the inner wall of the barrel (32); S3. Restart the second electric push rod (58), the second electric push rod (58) pushes the storage box (51) to slide on one side of the T-shaped plate (14), and at the same time the sliding pin (56) slides on the guide block ( 53), so when the storage box (51) is pushed, the lower cover (52) will automatically open, and the concrete in the storage box (51) slides down into the mold (12) through the lower cover (52); S4, then continue to convey, the mould (12) pushes the mould (12) to move forward, when the mould (12) passes the scraper (71), the scraper (71) can smooth the concrete in the mould (12); S5. Finally, when the mold (12) moves to the bottom of the sliding plate (48), the first electric push rod (43) is activated, and the first electric push rod (43) drives the sliding plate (48) to press down, so that the sliding plate (48) ) on the top of the mold (12), start the third motor (81), the third motor (81) drives the first connecting plate (82) to rotate, and the first connecting plate (82) drives the second connecting plate (83) to rotate , the second connecting plate (83) can drive the sliding plate (48) to move up and down at the bottom of the bottom plate (45), and through the high-speed rotation of the third motor (81), the sliding plate (48) can vibrate, so that the mold can be moved (12) The concrete is leveled, and the air bubbles in the concrete are eliminated.
