我们农场地势低洼,土质粘硬,开沟排水是生产的关键。过去,一直使用铧式开沟犁开沟,开沟后两侧形成沟堤,需要用大批人力平整后,才能排水。这样,不仅动力、劳力消耗大,而且开沟速度慢。_根据这种情况;我厂于一九七二年十月,开始设计制造了简易单盘旋转开沟机(图1)。经使用,效果良好。 Low-lying farmland, soil sticky hard, ditching drainage is the key to production. In the past, we had been using the furrow-type plow ditches to open the ditches on both sides after ditching, which required a large amount of manpower to be flat before drainage. In this way, not only power, labor-intensive, and slow ditching. According to this situation, in October 1972, our factory started to design and manufacture a simple single-disc rotary ditching machine (Figure 1). After use, the effect is good.
