我矿工区所产矿石,全用国产解放牌CA—340型倾卸汽车运往铁路仓库储存,然后由火车外运。运距7公里;全系山路,坡徒、弯急。矿石本身有时湿度较大,若遇雨天时,矿石往往成稀泥状。汽车运程中,当上坡或急转弯时,该后档板由于矿石后滑,档板后压突增,自动开闭机构失灵,档板被挤开,矿石沿路漏散,运到矿仓时几乎损失三分之一,有时还要多。这不仅造成严重的矿石浪费、增加公路保养量,而且对公路沿线造成严重污染。针对上述后档板自动开闭机构所存在的问题,经认真分析,找出其主要原因是:由于后档板自动开闭机构在山区使用时间一长,拉杆横轴就发生弯曲现象,因而整个开闭机构就显得
Mine ore mine area, all with domestic liberation card CA-340 type dump truck shipped to the railway warehouse storage, and then transported by train. Transport distance 7 km; the whole mountain, slope only, bend urgent. Sometimes the ore itself humidity is greater, in case of rainy days, the ore tends to become a thin sludge. Car transport, when the uphill or sharp turn, the tailgate after the ore due to slippery, baffle sudden surge, automatic opening and closing mechanism failure, the baffle is squeezed open, the ore along the road leakage, transported to the ore warehouse Almost lost one third, sometimes more. This not only caused serious ore waste, increased road maintenance, but also caused serious pollution along the highway. Aiming at the problems existing in the automatic opening and closing mechanism of the rear baffle plate, the main reason for the serious problem is that due to the long-time use of the automatic baffle plate opening and closing mechanism in the mountainous area, the horizontal axis of the pulling rod is bent, Opening and closing agencies appear
