The invention discloses a rail transit sand scattering device which comprises a sand scattering box, a sand outlet is formed in the bottom end of the sand scattering box, a sieving plate is arranged at the sand outlet, and a stirring assembly, an anti-blocking assembly and an auxiliary protection assembly are arranged in the sand scattering box. According to the sand scattering box for rail transit, the stirring rod is additionally arranged in the sand scattering box for rail transit, and after the driving motor is started, the stirring rod can be driven to stir sand to avoid caking; an inserting rod is matched with positive and negative rotation of a driving motor to perform piston motion to dredge the screening plate, and sand is prevented from being accumulated or blocked at the position of the screening plate; the horizontal moving plate moves back and forth, on one hand, the flowing direction of sand at the sand outlet is guided, on the other hand, when sand scattering is not needed, the horizontal moving plate can seal the sand outlet, the sand is prevented from flowing out, and external water vapor can be prevented from entering; and color-changing silica gel balls are placed in the drawable placement box and used for adsorbing moisture of sand in the storage box.
本发明公开了一种轨道交通撒沙装置,包括撒沙箱,撒沙箱的底端设有出沙口,出沙口位置处设有过筛板,撒沙箱内设有搅拌组件、防堵组件以及辅助防护组件。本发明在轨道交通用撒沙箱内部增设搅拌杆,在驱动电机启动后,可以带动搅拌杆对沙子进行搅拌避免结块;插杆配合驱动电机的正反转转动呈活塞运动对过筛板进行疏通,防止沙子在过筛板位置堆积或堵塞;平移板的往返移动一方面将出沙口位置的沙子的流向进行引导,另一方面在不需要撒沙时,平移板可以对出沙口进行密封,防止沙子流出可以避免外部水汽进入;可抽拉放置盒内部放置会变色的硅胶球,对存储箱内部沙子的水分进行吸附。
