A vinyl sheet boring machine for seeding and tunnel cultivation is provided to easily transport vinyl sheets by cutting a lower vinyl sheet, perforating only an upper vinyl sheet, and then winding up the vinyl sheet around a roll. The vinyl sheet boring machine for seeding and tunnel cultivation is composed of plural frames(13) radially installed at both drums(12) of a shaft(11) rotatively installed between first posts(10) and borers(20) mounted in a guide hole(13a) bored through the frame and composed of a fixing needle and a cutting blade installed at the lower center and the outside of a rotary plate turned by a motor to make holes(31a) on a vinyl sheet(30). The vinyl sheet wound on one roll is wound around the other roll and transferred through a gap between guide rollers. The vinyl sheet passing through the lower side of both drums is overlapped and transferred with blocking up both ends of upper and lower vinyl sheets(31,32). A blade(62) is installed at an upper guide piece(61) of a second post(60) mounted at the lower side of one guide roller to cut the center of the lower vinyl sheet. Round support rods(71) arranged at the upper side of third posts(70) installed at the lower side of the drums are positioned in the upper and lower vinyl sheets through a cut groove(32a) of the lower vinyl sheet. The borer makes the hole only on the upper vinyl sheet by supporting the underside of the upper vinyl sheet. |
