1 概述轨道卸车机是起卸散装物料比较通用的一种大型铁路机械,取料形式与埋刮板机相类似。当链斗由货车车箱内掏取物料时(如砂、碎石、煤和其它矿物碎料),沉积在物料表面或混杂在物料间的粉尘被击扬起来弥散在空间。虽然料面经湿式处理,但是当链斗掏取深度h大于物料湿润厚度h′,即h≥h′时,仍然是尘扬四起。如果采用连续湿润方法,由于卸车机一次性储水量有限(≤2t),而每卸空50t/节货车需耗水0.6t左右,货位系列为6～9节,因此,必须中途加水方能继续卸料,这样给卸车作业带
1 Overview Rail unloading machine is a kind of large-scale railway machinery that unloads bulk materials. It is similar to buried screed machine. When the bucket is picked up from the wagon box (such as sand, gravel, coal and other mineral scraps), the dust deposited on the surface of the material or mixed in the material is bombarded and dispersed in the space. Although the material surface is wet processed, when the chain bucket extraction depth h is greater than the material wet thickness h′, ie, h≥h′, it is still dusty. If the continuous wetting method is adopted, since the unloading machine has a limited one-time storage capacity (≤ 2t), and each unloaded 50t/kilogram truck needs to consume about 0.6t water, the cargo space series is 6-9 sections, therefore, water must be added halfway Continue unloading, this way to the unloading operation
