PROBLEM TO BE SOLVED: To provide a concrete mixer truck, a control device, and a rotation control method of a mixer drum capable of realizing energy saving of rotation power of the mixer drum when an engine is stopped.SOLUTION: A concrete mixer truck 100 comprises a vehicle body part 10, a first drive circuit 51, and a second drive circuit 52. The first drive circuit 51 comprises a hydraulic motor 12 for rotating a mixer drum 1 and a first hydraulic pump 11 for supplying a pressure oil to the hydraulic motor 12 by being driven by power of an engine 3. The second drive circuit 52 comprises: a storage battery (a second battery 21) for storing the output of an electric generator 4; an electric motor 22 driven by the electric discharge by the storage battery; a second hydraulic pump 23 for supplying the pressure oil to the hydraulic motor 12 by being driven by the electric motor 22; and an electric discharge control part 25. The electric discharge control part 25 detects a charging amount of the storage battery when receiving an idling stop signal from a control part 6, and makes the storage battery pulse-discharge at a lower duty ratio as the charging amount is higher if the charging amount exceeds a predetermined value.

    【課題】エンジン停止時におけるミキサドラムの回転電力の省エネルギ化を実現することができるミキサ車、制御装置およびミキサドラムの回転制御方法を提供する。【解決手段】ミキサ車100は、車体部10と、第1の駆動回路51と、第2の駆動回路52とを具備する。第1の駆動回路51は、ミキサドラム1を回転させる油圧モータ12と、エンジン3の動力で駆動され油圧モータ12へ圧油を供給する第1の油圧ポンプ11とを有する。第2の駆動回路52は、発電機4の出力を蓄電する蓄電池(第2のバッテリ21)と、上記蓄電池による放電で駆動される電動モータ22と、電動モータ22で駆動され油圧モータ12へ圧油を供給する第2の油圧ポンプ23と、放電制御部25と、を有する。放電制御部25は、制御部6からアイドリングストップ信号を受信したときに上記蓄電池の充電量を検出し、上記充電量が所定値を超えている場合は、上記充電量が高いほど低いデューティ比で上記蓄電池をパルス放電させる。【選択図】図2
