Abstract
This invention discloses an automatic grouting device for composite slab joints, relating to the field of composite slab installation. It includes a mixing cylinder with a stirring assembly at its center; a discharge hopper at the bottom of the mixing cylinder, with a booster pump installed at the bottom of the discharge hopper; and a pair of mounting plates symmetrically arranged on the outer wall of the mixing cylinder. A movable grouting assembly is mounted on the mounting plates and connected to the booster pump via a connecting hose. A sealing plate is positioned directly below the mixing cylinder, with a guide rod at one top end of the sealing plate slidably connected to the mounting plate, and a movable drive assembly at the other end of the sealing plate, connected to the mounting plate at the other end. A connecting groove is formed at the top of the sealing plate, and grouting and venting holes are evenly spaced within the connecting groove. This invention effectively and conveniently seals and grouts the joints of composite slabs, thereby facilitating the sealing of the composite slab joints.
