[0055] The height of the impact plate 45 is adjusted by the threaded installation between the impact plate 45 and the slide column 43;

[0062] Meanwhile, when the lower pressing plate 4 presses the concrete block, the push plate 32 is pushed to move downwards in the through slot 30, and the second spring 34 is compressed; when the lower pressing plate 4 is reset to rise, the pushing force of the push plate 32 disappears, the second spring 34 is reset, the push plate 32 is pushed to rise, and the push plate 32 is vibrated; meanwhile, the second motor 48 drives the third gear 49 to rotate, drives the second face gear 47 and the transmission rod 46 to rotate, drives the horizontal rod 38 and the second gear 39 to rotate, drives the first face gear 37 and the vertical rod 36 to rotate, drives the vibration base plate 40 to rotate along the fixed ring 41; through the cooperation between the vibration base plate 40 and the vibration top plate 44, the vibration top plate 44 is pushed to vibrate up and down, the slide column 43 is driven to slide downwards along the through hole 42, the impact plate 45 continuously impacts the bottom surface of the push plate 32, and the push plate 32 is continuously vibrated;
