[0002] The reclaimer is a highly efficient and professional reclaiming equipment used in bulk cargo yards such as coal ports and power plants. Through the continuous operation of the bucket wheel and the rotation of the boom, the coal is transferred from the yard to the cantilever belt conveyor, and then the coal is loaded onto the ship through the operation of various levels of conveyor belts. The bucket wheel is fixed to the bucket wheel body by a pin shaft and fastening bolts. The fixed pin shaft is a stepped shaft, and the wedge block passes through the square hole at one end of the pin shaft and is welded to the outside of the bucket wheel body. When reclaiming, the bucket wheel is subjected to the vertical and lateral composite reaction forces of the stockpile.

The machine must be shut down to replace a new bucket wheel, which seriously affects the reclaiming efficiency. Therefore, a reclaimer bucket wheel fixing device that is not easy to fall off is required to prevent the fixed pin shaft from falling off and the bucket wheel from being damaged.
