The invention provides an automatic sand spreading device of an electric locomotive. The device comprises an air pump, an electromagnetic valve, an air cylinder, a controller and a sand spreading rod,wherein the controller is connected with the electromagnetic valve and controls the opening size of the electromagnetic valve according to the running speed of the electric locomotive; the cylinder is respectively connected with the electromagnetic valve and the sand spreading rod; air pressure generated by the air pump enters the air cylinder through control of the electromagnetic valve, and theair cylinder stretches out and draws back to drive the sand spreading rod to spread sand. By means of the device, the electric locomotive automatically controls the sand spreading rod to accurately and evenly spread sand, and manual labor is replaced by automatic control.
