The invention provides a sanding device for a locomotive, which comprises a sanding main body, a plurality of sanding nozzles and a plurality of sanding nozzles, the air inlet cavity is arranged in the sanding main body and is respectively communicated with the sanding runner and the locomotive sand box, and a heater is arranged in the air inlet cavity; the first air inlet flow channel and the second air inlet flow channel are respectively communicated with the air inlet cavity; the sanding air cavity is communicated with the first air inlet flow channel, a sanding air nozzle is arranged in the sanding air cavity, and the spraying direction of the sanding air nozzle faces the sand outlet of the sanding flow channel; wherein in the first working state, the normal-pressure sanding air sourceenters the sanding air cavity and enters the sanding flow channel through the first air inlet flow channel to be stirred, and sand grains are blown out under the combined action of the sanding air nozzle, so that sanding operation is carried out; and in the second working state, the normal-pressure air source enters the air inlet cavity through the second air inlet flow channel and enters the locomotive sand box and the sanding flow channel after being heated by the heater, so that sand grains are kept loose and dry.

    本发明提供了一种用于机车的撒砂装置,包括:撒砂主体,在撒砂主体的内部构造有撒砂流道;设置在撒砂主体的内部且分别与撒砂流道和机车砂箱连通的进风腔体,在进风腔体内设有加热器;分别与进风腔体连通的第一进风流道和第二进风流道;与第一进风流道连通的撒砂风腔,在撒砂风腔内设有撒砂风嘴,撒砂风嘴的喷射方向朝向撒砂流道的出砂口;其中,在第一工作状态下,常压撒砂气源进入撒砂风腔并通过第一进风流道进入撒砂流道搅动,并在撒砂风嘴的共同作用下吹出砂粒,从而进行撒砂作业;在第二工作状态下,常压气源通过第二进风流道进入进风腔体,并通过加热器加热后进入机车砂箱和撒砂流道,从而使砂粒保持疏松干燥。
