APPARATUS FOR WEIGHING CONCRETE MATERIAL

摘要

PROBLEM TO BE SOLVED: To accurately weigh the mass of aggregate and water. SOLUTION: An apparatus 1 for weighing concrete material is principally composed of an aggregate hopper 3 as an aggregate feed means for feeding fine aggregate 2 being the aggregate; a feed water pipe 4 as a feed water means; a weighing tank 5 wherein the fine aggregate 2 fed from the aggregate hopper 3 together with water fed from the water feed pipe 4 are stored as immersed aggregate mass weighing means for weighing mass of the immersed aggregate in the weighing tank; an electrode type sensor 7 as a water level measuring means for measuring a water level of the immersed aggregate in the weighing tank 5; and a water level holding device 8 as a water level holding means for holding a water level of the immersed aggregate in the weighing tank 5 at a required water level.
