Vibrating device for precast beam and slab production

The utility model relates to the technical field of vibrating devices, and discloses a vibrating device for precast beam and slab production, the vibrating device comprises two guide frames, a supporting frame and a movable plate, the two ends of the bottom of the supporting frame are slidably connected to the interiors of the two guide frames correspondingly, and the movable plate is located in the supporting frame; a plurality of vibrators are fixedly arranged at the bottom end of the movable plate side by side, sliding grooves are formed in the two inner side walls of the supporting frame correspondingly, and connecting plates movably penetrate through the interiors of the two sliding grooves correspondingly. According to the scheme, two first threaded rods are driven by power shafts of two first motors to rotate in the same direction, and the two first threaded rods apply threaded thrust to two connecting plates, so that the two connecting plates drive a movable plate to descend; and a plurality of vibrat
