CONCRETE MIXER, METHOD FOR WASHING CONCRETE MIXER, AND METHOD FOR PRODUCING READY-MIXED CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide a concrete mixer which can efficiently carry out the washing mortar in concrete adherent to arm parts and blades which are difficult to be washed, without causing abrasion by friction and collision between metal parts.;SOLUTION: The compulsive horizontal two-shaft type concrete mixer A includes a kneading vessel 11, a pair of mixer shafts 12 which can rotate around a horizontal shaft in the mixing vessel 11, an arm part 13 suitable for each mixer shaft 12, and the blade 14 attached to each arm part 13. In the concrete mixer A, a mixer shaft side conduit run 121 and an arm part side conduit run 131 are installed in the mixer shaft 12 and the arm part 13, respectively, and a spray means 3 is provided, which sprays high-pressure water or compressed air which contributes to washing or the mixture of them toward arm part 13 and the blades 14 using the mixer shaft side conduit run 121 and the arm part side conduit run 131.;COPYRIGHT: (C)2010,JPO&INPIT
