我厂第二车间在技术革命中搞出来一台土抛砂机,大部分利用废料制成,结构较简单.其桔构见右面示意图,臂下有轮,可在基座上前后滑动,基座又可绕支柱回转.整个机器下亦有轮子可移动.抛砂机由900转/分的电机直接拖动,运砂皮带经二级减速齿轮来带动. The second workshop in our factory came out in the technological revolution, a soil throwing machine, most of the use of waste materials, the structure is relatively simple. The orange structure, see the right diagram, arms under the wheel, can slide back and forth on the base, base The seat can be revolved around the column. The whole machine also has a wheel that can be moved. The sand-throwing machine is directly driven by a motor at 900 rpm, and the sand-carrying belt is driven by a second reduction gear.
