Abstract

PURPOSE: A ventilation fan for light stone hen house for vinyl house comprising a means for connecting the ends of two pipe arranged in parallel, a frame surrounding an impeller fixed coaxially with an impeller shaft supported by the pipes, and fitting holes formed in the connection means.
CONSTITUTION: Two pipes 1 and 2 are folded into U-shape and arranged in parallel. Connection means 3 and 4 are arranged in parallel with and perpendicular to an impeller shaft 5, and welded to sides 3a and 4b while the pipes 1 and 2 are kept in parallel and the distances from the bottom faces of the means 3 and 4 to the upper ends of the pipes 1 and 2 are adjusted. Then the shaft 5 is rotatably supported by a shaft supporting means 6, and an impeller 7 is fitted. Similarly, a motor supporting member 8 is fixed and a motor 9 is mounted. After pulleys 11 and 12 are fitted and a belt 13 is put on, corners 18aW18d of a quadrilateral frame 17 are welded and the means 3 and 4 are formed with fitting holes 19.
