在批林批孔运动的推动下,北京市第三建筑工程公司试制成功自动筛砂机。 一、构造 该机由电动机带动偏心轮连杆作往复运动,带动筛子筛砂。砂子通过皮带运输机上的12个斗提升至最高点,落到筛子内,再由筛下的皮带输送出来,砂漏由另一边输出。行走部分由电动机、离合器通过链 Under the impetus of the approval of the batches of forests and holes, Beijing No.3 Construction Engineering Co., Ltd. successfully trial-produced automatic sand-sanding machines. First, the structure of the machine driven by the motor eccentric link for reciprocating motion, driven sieve sieve sand. The sand is lifted to the highest point by 12 buckets on the belt conveyor, falls into the screen, and is conveyed by the belt under the screen. The hourglass is output from the other side. Walking section consists of motor, clutch through chain
