PROBLEM TO BE SOLVED: To provide an omasum washer in which damage to a motor shaft in normal/reverse rotation switching operation can be eliminated and scattering of rinse water to the outside of a tank can be prevented.SOLUTION: The omasum washer includes a first agitation body 3A and a second agitation body 3B with external diameters different in size inside a washing tank. The first agitation body 3A is configured in such a way that a plurality of agitating blades 2a are erected on a rotary circular plate 2 and a hollow shaft cylinder 12 is rotatably supported in a bearing 13a of a housing 13 of the washing tank 4. The second agitation body 3B is configured in such a way that a plurality of agitating blades 1a are erected on a rotary plate 1 and a rotary shaft 11 is inserted into the hollow shaft cylinder 12 and rotatably supported by a bearing 12a provided in the hollow shaft cylinder 12. Inside and outside agitation bodies that are the first agitation body 3A and second agitation body are connected to a normal rotation drive motor 17 and a reverse rotation drive motor 18 respectively.COPYRIGHT: (C)2015,JPO&INPIT【課題】正逆回転切り替え動作におけるモーター軸の損傷を解消し、また、槽外への洗浄水の飛散を防止することができるセンマイ洗浄機を提供する。【解決手段】洗浄槽4の内に外径が大小異なる第1の撹拌体3A及び第2の撹拌体3Bを備える。第1の撹拌体3Aを、回転円板2に複数の撹拌羽根2aを立設して構成し、その中空軸筒12を洗浄槽4のハウジング13の軸受け13aに回転自在に支承する。第2の撹拌体3Bを、回転板1に複数の撹拌羽根1aを立設して構成し、その回転軸11を、中空軸筒12内に挿通し、この中空軸筒12内に設けた軸受け12aで回転自在に支承する。内外の撹拌体、すなわち、第1の撹拌体3A及び第2の撹拌体3Bを、正転用駆動モーター17及び逆転用駆動モーター18に各々連結する。【選択図】 図1
