DRAINAGE EQUIPMENT FOR RICE FIELD

摘要

PROBLEM TO BE SOLVED: To obtain a drainage equipment for rice field that can readily control the sluice level by setting guide rails so as to surround a support and constituting the sluice so that the height position may be adjusted in the height direction with an adjusting mechanism that is integrated to the guide rails. SOLUTION: In the rice field water-drainage equipment that has such a structure that the sluice 4 is supported by the pole installed in the ground, the support pole 5 is surrounded by a tubular guide rail 13 and the sluice 4 is constructed integrally with the guide rail 13 so that the position in the vertical direction may be controlled by an adjusting mechanism 3. In another embodiment, a detachable wedge 32 may be inserted into the gap 17 between the support pole 5 and the guide rail 13.
