Backfilling device

The utility model relates to a backfilling device which comprises a movable base arranged on the ground on the periphery of a strip-shaped backfilling area, and a pair of rails arranged in the lengthdirection of the strip-shaped backfilling area are formed on the base. The bracket is arranged on the rail in a sliding manner; a containing space is formed in the hopper, the hopper is fixed to the support, a feeding port is formed in the top of the hopper, a discharging port matched with the strip-shaped backfill area is formed in the bottom of the hopper, and the discharging port is located above the strip-shaped backfill area; and the vibrator is fixed on the outer surface of the hopper. According to the device, the support can move in the length direction of the strip-shaped backfill areathrough the pair of rails, and the situation that materials scatter out of the strip-shaped backfill area in the backfill process due to the fact that the support deviates from the strip-shaped backfill area is prevented.
