To suppress vibration of a vehicle when a mixer drum is washed.SOLUTION: A controller 20 of a mixer drum washing device 100 controls a drive unit 4 such that rotation number of a mixer drum 2 transitions according to a target washing pattern in which a target rotation number of the mixer drum 2 in washing has been set. The target rotation number of the mixer drum 2 in the target washing pattern is set so as to increase to a put-in side washing rotation number DN1 and a discharge side washing rotation number DN2 at a prescribed temporal change rate, or to lower from the put-in side washing rotation number DN1 and the discharge side washing rotation number DN2 at the prescribed temporal change rate.SELECTED DRAWING: Figure 3 【課題】ミキサドラムを洗浄する際に生じる車両の振動を抑制する。【解決手段】ミキサドラム洗浄装置１００のコントローラ２０は、洗浄時のミキサドラム２の目標回転数が設定された目標洗浄パターンに従ってミキサドラム２の回転数が推移するように駆動装置４を制御する。目標洗浄パターンのミキサドラム２の目標回転数は、所定の時間変化率で投入側洗浄回転数ＤＮ１及び排出側洗浄回転数ＤＮ２まで上昇、または、所定の時間変化率で投入側洗浄回転数ＤＮ１及び排出側洗浄回転数ＤＮ２から低下するように設定される。【選択図】図３
