S276型滚筒式连续混砂机是青岛铸造机械厂1967年第一季度试制成功的新产品。该机是混砂和松砂联合作用的混砂机,适合于流水线的机械化车间混合型砂之用。由于该机是连续工作的,所以需有一套比较准确的均匀定量给料装置(见封四照片图)。该机由滚筒、刮板、松砂叶轮、碾辊、托轮、支架等部件组成。滚筒由托轮的橡胶轮支承。齿轮减速电动机用双排链子驱动托轮轴,并通过橡胶轮与滚筒壁的摩擦而使滚筒转动。滚筒内的碾辊借助于设在滚筒外的摇 S276 Drum Continuous Mixer Qingdao Casting Machinery Factory in 1967 the first quarter trial success of new products. This machine is a sand mixer that combines sand and loose sand. It is suitable for the mixed sand of mechanized workshop in the pipeline. As the machine is continuous work, so there is a need for a more accurate uniform dosing device (see the cover four photos). The machine consists of drum, scraper, loose sand impeller, roller, roller, bracket and other components. The drum is supported by the rubber wheels of the rollers. Geared motors use a double row chain to drive the carrier shaft and rotate the drum by friction between the rubber wheel and the drum wall. The roller in the roller is provided by the roller provided outside the roller
