The conveyor belt 1 drives the sand and gravel to move, and the dust between the sand and gravel passes through the ash falling holes 13 to the vicinity of the ash suction base 3. The exhaust device 4 provides suction for the ash suction base 3 to suck the dust from the ash leakage plate 6 into the ash suction base 3. When the conveyor belt 1 transports the sand and gravel to the highest point, the sand and gravel fall, and the dust generated by the fall is sucked into the ash suction base 3 from the side ash suction plate 61, and the dust is prevented from being blown out by the ash baffle plate 41. When not working, open the seat door 5 to clean the inside of the ash suction base 3, and the rain shelter 21 protects the conveyor belt 1 from rain. The sand and gravel that mistakenly enter between the conveyor belt 1 and the ash suction base 3 slide out from the bottom support plate 62.
