在毛主席革命路线指引下,我公司为了解决人工筛砂的笨重体力劳动,在参观北京市第五建筑工程公局的筛砂机的基础上,加以改进,试制成了群英3302电动筛砂机。1.构造及工作原理电动筛砂机主要由车架、驾驶室、上砂架、滚筛、出砂架、砂漏箱等六部分组成(图1)。机身全长6米、宽2.10米,高2.50米。筛砂时,由驾驶员将筛砂机驾近砂堆,上砂架落地并将铲斗插入砂堆中。皮带 Under the guidance of Chairman Mao’s revolutionary route, in order to solve the heavy manual labor of artificial sand screening, the company improved the sand screening machine of the Fifth Construction Engineering Bureau in Beijing, and made a trial of the Qunying 3302 electric screen sand. machine. 1. Structure and working principle Electric sand screening machine mainly consists of six parts: frame, cab, sand frame, roller screen, sand frame and sand leak box (Figure 1). The fuselage is 6 meters long, 2.10 meters wide and 2.50 meters high. When sand is sieved, the driver will drive the sand-sanding machine close to the sand pile, and the upper sand frame will land and insert the bucket into the sand pile. Belt
