A method for using the agricultural seed coating device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: The seeds to be processed are first placed in the buffer tank (100), and then the feeding roller (107) is driven to rotate by the driving motor (105). When the receiving notch (126) on the feeding roller (107) is set upward, the receiving notch (126) will be filled with seeds. When the receiving notch (126) filled with seeds turns downward, the filled seeds will fall and then be received by the receiving guide plate (108). The seeds will enter the buffer cylinder ring (200) along the receiving guide plate (108); Step 2: Under the action of the spray mechanism, the seed coating operation is completed. During the coating process, the air inside the buffer cylinder ring (200) is heated by the heating tube, so that the coated seeds are dried. The dried seeds enter the collection box (300) and are collected.
