PROBLEM TO BE SOLVED: To provide an inexpensive powder granule unloading device of simple construction, which prevents interference between rear wheels and a fertilizer conveying hose when used for a traveling vehicle such as a rice transplanter, thus the supporting position of the conveying hose is stabilized. SOLUTION: The powder granule unloading device has the following construction: Multiple unloading sections 61 via which powder granules in a grain tank 60 are to be unloaded are provided in parallel to each other, and is provided with: a conveying tube 62 for conveying powdery granules unloaded from an air conveying tube 68 and the unloading sections 61 toward the alignment direction of the unloading sections 61 to an unloading port 59, a collection tube 85 for collecting powder granules opposite to the air conveying tube 68 seen from the unloading sections 61, a path 83 having an opening/closing means between the retrieving tube 85 and the grain tank 60, a blower 67 sending air to the air conveying tube 68 and the collection tube 85, a means 86 for switching air feed between the air conveying tube 68 and the retrieving tube 85, an air suction tube 69 opposite to the unloading sections 61 seen from the collection tube 85 side, and a holder 65 for holding the conveying tube 62 on the air suction tube 69.
