A boundary stone construction apparatus is provided to minimize construction cost of curved boundary stone because the curved boundary stone can be easily carried out. A boundary stone construction apparatus comprises a base(1) and a boundary stone molding unit(2). The base comprises a plurality of wheels(11) and projecting knobs. The boundary stone molding unit is prepared on top of the base. The boundary stone molding unit takes concrete mixture or clay having viscosity and exhausts after mixing and molds the boundary stone. The boundary stone molding unit comprises a hopper(21), a driving unit(24), a mixture filling and moving pipe(22) and a molding unit(23). The hopper comprises a top input part(211) and a front opening. A pair of mixing screws are prepared inside the hopper. The driving unit rotates a pair of mixing screws. |
