The invention discloses a fire coal transportation device for a boiler. The fire coal transportation device comprises a first support and a second support, a first roller shaft and a second roller shaft are movably connected to the top end of the first support and the top end of the second support correspondingly, moreover, a conveying belt sleeves the first roller shaft and the second roller shaft, the middle of the first support is fixedly connected to the lower end of the second support through a supporting rod, a sliding groove is fixedly connected to the upper side of a rotating shaft, the lower side of the sliding groove is attached to the top end of a hydraulic arm, a base of the hydraulic arm is fixedly connected to the middle part of one side of the second support through screws.According to the fire coal transportation device, a traditional mode that coal needs to be added into a combustion chamber manually is changed, the coal is placed between partition plates on the conveying belt, the partition plates can guarantee that the coal can not fall off in the rising process, a motor drives the conveying belt to rotate to convey the coal to the top end, then the coal falls into the sliding groove, and the coal falls into the combustion chamber through the sliding groove.
