The invention relates to the technical field of railway equipment, in particular to a sand adding device which comprises a material conveying container, a first air supply device and a conveying pipeline, the material conveying container is provided with a feeding port and a discharging port which are oppositely arranged, the feeding port is located above the discharging port, a rotating shaft is arranged in the material conveying container, and the rotating shaft is provided with spiral blades; the rotating shaft can rotate around the axis of the rotating shaft relative to the material conveying container so as to push sand in the material conveying container to the discharging port. One end of the conveying pipeline is communicated with an air supply port of the first air supply device, and the other end of the conveying pipeline is used for being communicated with a sand box of a locomotive. During use, sand is loaded into the material conveying container from the feeding port, the spiral blade rotates around the axis of the spiral blade relative to the material conveying container along with the rotating shaft, axial thrust is provided for the sand in the material conveying container, and therefore the sand is pushed to the discharging port and enters the conveying pipeline, and the first air supply device supplies air to the conveying pipeline. And the sand in the conveying pipeline is conveyed into the sand box by utilizing air pressure.
本公开涉及铁路设备技术领域,尤其是涉及一种加砂装置,其包括输料容器、第一供气装置和输送管路,输料容器具有相对设置的进料口和出料口,进料口位于出料口的上方,输料容器内设置有转轴,转轴设置有螺旋叶片,转轴能够相对于输料容器绕其自身的轴线转动,以将输料容器内的砂子推向出料口;出料口与输送管路连通,输送管路的一端与第一供气装置的供气口连通,另一端用于与机车的砂箱连通。在使用时,将砂子从进料口装入输料容器内,螺旋叶片随转轴一起相对于输料容器绕其自身的轴线转动,向输料容器内的砂子提供轴向推力,从而将砂子推向出料口,并进入输送管路,第一供气装置向输送管路供气,利用空气压力将输送管路内的砂子送入砂箱内。
