The invention discloses a mechanical acceleration type locomotive tackifying and sanding device. The device comprises a sand box, and a flow control valve is arranged at the joint of the lower end ofthe sand box and a funnel; the device further comprises an accelerator used for accelerating sand particles; the lower end of the funnel is connected to a sand inlet of the accelerator through a hose;the accelerator comprises an impeller and a branch grinding wheel arranged in the center of the impeller; a directional sleeve is arranged outside the branch grinding wheel; the accelerator further comprises a plurality of blade positioning sleeves which are uniformly arranged on the impeller, a plurality of through holes are formed in the blade positioning sleeves, and the through holes correspond to the positions between every two adjacent blades; a sand outlet is formed in the lower end of the accelerator and is connected with a nozzle; and the device further comprises a first motor used for driving the impeller to rotate. Viscous particles are sprayed out in an accelerated mode through the high-speed rotating impeller, so compared with a pressure type sanding device and a gravity typesanding device, the device of the invention achieves a higher sanding speed, can effectively avoid airflow interference in the high-speed running process of a locomotive, and improves the particle spraying efficiency.

    本发明公开了一种机械加速式的机车增黏撒砂装置,包括砂箱、砂箱下端与漏斗连接处设置有流量控制阀;还包括用于对砂子颗粒进行加速的加速装置;漏斗下端通过软管连接到加速装置的进砂口;加速装置包括叶轮和设置在叶轮中心的分砂轮;分砂轮外设置有定向套;还包括均匀设置到叶轮上的多个叶片定向套上设置有多个通孔,通孔对应相邻两叶片之间位置;加速装置下端设置有出砂口,出砂口连接喷嘴;还包括用于带动叶轮转动的第一电机;本发明通过高速旋转叶轮将增黏颗粒加速喷出,相对于压力式和重力式撒砂装置,可以达到更高的撒砂速度;可有效避免机车高速行驶过程中的气流干扰,提高颗粒喷射效率。
