    • PROBLEM TO BE SOLVED: To provide a mixer drum driving device suited to maintain stable rotation of a mixer drum when supplying a working fluid from an independent hydraulic pressure supply source to a hydraulic motor.SOLUTION: A mixer drum driving device comprises: an auxiliary hydraulic pump 5 provided to be independent of a hydraulic pump 4 and supplying a working fluid by being driven by an electric motor 9; a pressure sensor 16 detecting a hydraulic pressure of the working fluid discharged from the auxiliary hydraulic pump 5; a switching valve 15 switching as to whether or not to supply the working fluid discharged from the auxiliary hydraulic pump 5 to the hydraulic motor 3; and a controller 7 controlling the switching valve 15 to be opened or closed. In a state in which the switching valve 15 switching as to whether or not to supply the working fluid from the auxiliary hydraulic pump 5 is closed and in which a mixer drum M is driven to rotate by the hydraulic pump 4, the switching valve 15 is opened if the hydraulic pressure of the working fluid from the auxiliary hydraulic pump 5 detected by the pressure sensor 16 is equal to or higher than a preset hydraulic pressure.
    • 要解决的问题:提供一种适于在从独立液压供应源向液压马达供应工作流体时保持搅拌滚筒的稳定旋转的搅拌筒驱动装置。解决方案:搅拌筒驱动装置包括:辅助液压 泵5设置为独立于液压泵4并通过由电动马达9驱动而供给工作流体; 检测从辅助液压泵5排出的工作流体的液压的压力传感器16; 切换阀15,切换是否将从辅助液压泵5排出的工作流体供给到液压马达3; 以及控制切换阀15打开或关闭的控制器7。 在关闭从副液压泵5供给工作流体的切换阀15切换的状态下,由液压泵4驱动搅拌筒M旋转的状态下,切换阀15为 如果由压力传感器16检测到的来自辅助液压泵5的工作流体的液压压力等于或高于预设液压压力,则打开。

    • PURPOSE:To efficiently perform mixing, by providing a turbine blade in a casing in a freely revolvable manner while mounting a stirring blade to the outer lower periphery of the drive shaft provided with the turbine blade. CONSTITUTION:A gas supply pipe 2 is connected to a casing 1 and a drive shaft 4 having a turbine blade 3 mounted to the outer periphery thereof is supported in a freely revolvable manner in the casing by a bearing 5 while a guide blade 6 is provided in the vicinity of the casing inlet. A hollow shaft 7 having a desired length is connected to the end of the drive shaft 4 through an axle joint 8 and a guide blade 9 is provided in the casing provided to the hollow part of the drive shaft 4 while exhaust gas utilized in revolving the turbine blade 3 is efficiently introduced into a suction port 4a while guided by the guide blade 9. The lower end of the hollow shaft 7 is opened so as to discharge the exhaust gas into a liquid from the opening end 7a of said shaft 7 and a stirring blade 10 is provided to the outer periphery of the lower end of the shaft 7.
