Abstract

PURPOSE: To accurately prevent the reverse malfunction of a mixer drum by providing the reverse operation preventive mechanism of an operator and its preventive release mechanism in the operation device of the mixer drum.
CONSTITUTION: An operator 24 is freely rotatingly supported on the operation panel 26 of an internal operation device 3 and a reverse operation preventive mechanism (a) consisting of a guide groove 27, lever 31, pin 33, and compressed spring 32 and a preventive release mechanism (b) consisting of the lever 31 and a push button 34 are provided at the rear facing the operation panel 26 of this operator 24. When the operator 24 is set to stop position (S), since the pin 33 is fit in the lower end of the guide groove 27, the operator 24 can be operated forward (clockwise), but it cannot be done backward (counterclockwise). When the push button 34 is pressed and the pin 33 is detached from the guide groove 27, the operator 24 can be operated backward. As a result, the reverse malfunction of the mixer drum can accurately be prevented.
