为了改变铸工车间用人力筛砂的落后面貌,我们遵照毛主席“独立自主、自力更生”的伟大教导,自己动手,在一个月的时间里,经过十余次的反复试验,试制成一台移动式无声偏心振动筛砂机,其特点是:1.重量轻,体积小,移动方便。2.结构简单,制造容易,操作方便。3.无响声,效率高,适应战备。4.改变筛网规格,可扩大使用范围。其工作原理(见附图),电动机过皮带轮减速后,带动偏心轮,偏心轮上的垂直轴拖动箱盘作水平的往复运动,该运动一方面受到安
In order to change the backward appearance of the artificial screen sand used in the casting workshop, we followed the great teachings of Chairman Mao’s “independent, self-reliant” and started to do it myself. After a dozen trials and tests in one month, we tried to make a mobile model. Silent eccentric vibration sieve sand machine, its characteristics are: 1. Light weight, small size, easy to move. 2. The structure is simple, easy to manufacture and easy to operate. 3. No noise, high efficiency, adapt to combat readiness. 4. Change the screen specifications to expand the scope of use. Its working principle (see the attached drawing), after the motor decelerates through the belt pulley, drives the eccentric wheel, and the vertical axis on the eccentric wheel drags the box plate to make a horizontal reciprocating motion.
