PURPOSE: A paving device for a boundary stone is provided to obtain driving force using reaction force and to improve the filling efficiency of mortar when boundary stones are spread.;CONSTITUTION: A paving device for a boundary stone comprises a hopper(10), a support body(20), a wheel unit, a screw cylinder(40), an extrusion screw, a drive unit(60), and a molding plate(70). The hopper receives mortar from an upper opening(11) and supplies the received mortar through a lower opening. The support body supports the hopper and is extended in a longitudinal direction. The wheel unit is composed of front wheels(31) and rear wheels for supporting the support body. The screw cylinder is connected to the lower opening and is coupled to the bottom of the support body. The extrusion screw is located at the bottom of the hopper and is formed inside the screw cylinder to be rotatable. The drive unit is composed of a drive motor and a speed reducer(61) and rotates the extrusion screw. The molding plate is coupled to the rear end of the screw cylinder and molds the supplied mortar.;COPYRIGHT KIPO 2013
