The driving wheel 502 forms friction with the surface of the carriage and can drive the adjustment unit 5 and the power source 1 to move. The power source 1 can adjust the discharge position of the discharge pipe in the carriage. After the discharge pipe moves to the discharge position, there is no grain around the discharge pipe to push the detection unit 4.
