The invention relates to a sand spreading device for a mining electric locomotive. The sand spreading device comprises a sand box, and a cross-shaped separating plate is arranged in the sand box; in addition, the interior of the cross-shaped separating plate is of a hollow structure, and a plurality of electric heating wires are arranged in the hollow structure of the cross-shaped separating plate; a temperature adjusting device and a power utilization safety protection device are arranged outside the sand box; and a sand outlet is formed in the bottom of the sand box, a spiral material pushing rod is arranged at the sand outlet, and the other end of the spiral material pushing rod penetrates the sand box. A driven bevel gear is connected to the position, outside the sand box, of the spiral material pushing rod, a pneumatic motor is arranged on the outer wall of the sand box, and a driving bevel gear meshed with the driven bevel gear is connected to the output end of the pneumatic motor; and a sand outlet pipe is connected to the sand outlet. The sand spreading device has the beneficial effects that as the cross-shaped separating plate is arranged in the sand box, and the electric heating wires are arranged in the cross-shaped separating plate, so that sand in the sand box can be effectively dried, and the humid sand can be prevented from blocking the sand outlet; and meanwhile, spiral material pushing rod is arranged so that the sand spreading uniformity can be effectively guaranteed.
