TRUCK MIXER AND ESTIMATION METHOD FOR TEMPERATURE OF READY MIXED-CONCRETE

摘要

PROBLEM TO BE SOLVED: To make it possible to control a temperature of a ready mixed-concrete by a simple method.SOLUTION: A temperature management controller 21 of a truck mixer 100 is equipped with: a drive time measurement part 25 for measuring a drive time A during which a mixer drum 2 is driven while loading a ready mixed-concrete therein; a drum surface temperature estimation part 26 for estimating a surface temperature B of the mixer drum 2; and a ready mixed-concrete estimation part 27 which estimates a temperature C of the ready mixed-concrete loaded in the mixer drum 2 on the basis of the measured drive time A of the mixer drum 2 and the estimated surface temperature B of the mixer drum 2.SELECTED DRAWING: Figure 2
