PROBLEM TO BE SOLVED: To prevent grains from being damaged to lead to a drop of the commercial value largely, resulting from transporting only with a suction wind. SOLUTION: Inside a suction hose 5 is sucked by a suction device 9 installed at the end of a suction hose 5 and grains as object to be transported 1 are sucked by a suction nozzle 6 at the starting part of the hose 5, whereby the sucked grains are separated from the suction wind which is exhausted from an intermediate exhaust hole provided upstream in the transporting direction of the intermediate part of the hose 5, and the grains separated from the suction wind are transported to downstream in the transporting direction and let fall from a grain ejecting hole 7 to be ejected, and during ejection of the grains, a certain amount of grains are passed at all times through a stagnation chamber so as to hinder the external air from flowing in toward the intermediate exhaust hole from the grain ejecting hole 7 which is left open.
