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.
