WEIGHING EQUIPMENT FOR CONCRETE MATERIAL

摘要

A weighing equipment (1) for concrete material, comprising an aggregate hopper (3) as an aggregate feed means for feeding fine aggregate (2) as aggregate, a water supply pipe (4) as a water supply means, an aggregate weighing bin (51) for storing and weighing the fine aggregate (2) supplied from the aggregate hopper (3), a weighing tank (5) for storing as water−immersed aggregate the fine aggregate (2) supplied from the aggregate hopper (3) together with water supplied through the water supply pipe (4), a load cell (6) as a water−immersed aggregate mass weighing means for weighing the mass of the water−immersed aggregate in the weighing tank, an electrode sensor (7) as a water level measuring means for measuring the level of the water−immersed aggregate in the weighing tank (5), and a level holding device (8) as a level holding means for holding the level of the water−immersed aggregate in the weighing tank (5) at a specified level.
