A road prefabricated slab laying device according to claim 5, characterized in that: The driving assembly (250) also includes a second sprocket (252) rotatably connected to the front end face of the discharge box (120), the front end face of the second sprocket (252) being fixedly connected to an incomplete gear (253), the other end of one of the rotating rods (231) being fixedly connected to a third sprocket (254), a second chain (255) being transmission-connected between the third sprocket (254) and the outer surface of the second sprocket (252), and the incomplete gear (253) being meshed with an acceleration gear.

7. A road prefabricated slab paving device according to claim 6, characterized in that: The support assembly (270) includes a support rod (271) hinged at the bottom of the feed door (130), a support wheel (272) is installed at the bottom of the support rod (271), and a connecting rod (273) is hinged between the support wheel (272), the support rod (271) and one side of the movable plate (110).

8. A road prefabricated slab paving device according to claim 7, characterized in that: The laying module (200) further comprises an electric push rod (280) hinged on the rear end surface of the unloading box (120), and the output shaft of the electric push rod (280) is hinged to the bottom of the feed door (130).

9. A road prefabricated slab laying device according to claim 6, characterized in that: The sealing assembly (290) includes a sealing plate (292) slidably connected to the inside of the laying box (150), one side of the sealing plate (292) extends out of the outside of the laying box (150), two reinforcement plates are fixedly installed at the bottom of the movable plate (110), two cylinders (291) are fixedly installed between the insides of the two reinforcement plates, and the output shafts of the two cylinders (291) are fixedly connected to the sealing plate (292).

10. A method for laying prefabricated road panels according to claims 1-9, characterized in that: The following steps are involved: S1. First, the feed door (130) is opened by the electric push rod (280). When the feed door (130) is opened, the connecting rod (273) will push the support rod (271) to a vertical state, and the support wheel (272) will contact the ground, thereby supporting the feed door (130). Subsequently, the staff will put the prefabricated panels to be laid into the U-shaped frame (220) and place them between the two sets of auxiliary rollers, and arrange the excess prefabricated panels on the feed door (130). S2. When the driving motor is turned on and the device is pushed to move, the driving motor will drive the rotating rod (231) to rotate and drive the two first chains (233) to roll through the two first sprockets (232), so that the first chains (233) drive the push plate (240) to roll, so that the push plate (240) pushes the prefabricated board through the interior of the connection box (260) and enters the interior of the laying box (150) through the rolling of multiple rollers for alignment. S3, opening the cylinder (291) to drive the sealing plate (292) to withdraw from the laying box (150) to release the seal of the laying box (150) so as to lay the prefabricated panels, and subsequently pushing back the sealing plate (292) to continue sealing the laying box (150). S4, the transmission of the third sprocket (254), the second chain (255), the second sprocket (252) and the incomplete gear (253) is coordinated with the intermittent transmission bidirectional screw rod (251) to rotate, so that the two sliding plates (211) intermittently move closer to each other, so that the connecting frame (212) pushes the top plate to rise, and the U-shaped frame (220) is intermittently raised and lowered to raise another prefabricated plate to the height of the push plate (240), so that the push plate (240) continues to push, so that the device can complete continuous laying.
