PROBLEM TO BE SOLVED: To provide a snow carrying screw, in which snow can be carried with less labor, at lower cost, and in shorter time to solve problems of labor, cost, and time required to process snow in snowy area. SOLUTION: In this snow carrying screw, one pitch is properly parted, and each part is provided with a through hole to be connected by a shaft. Gear-like coupling means are disposed at both ends for transmission of rotation, and the parts are engaged and connected in order, with their phase shifted. It is thus usable for carrying snow and crushing blocks of snow. COPYRIGHT: (C)2005,JPO&NCIPI
