PROBLEM TO BE SOLVED: To make a transfer defect easily avoidable while transferring granular bodies to a supply part by granular body transferring air by distributively supplying the granular body transferring air from a blower to a granular body send-out part in each of a plurality of payout mechanisms.SOLUTION: A biforked part 42a is arranged at a distribution supply pipe 43 which distributes and supplies granular body transfer air to a granular body send-out part 38 of each of a plurality of payout mechanisms 31, and at an air duct 42 which sends the granular body transfer air from a blower 32 into the distribution supply pipe 43. A left discharge port 42b possessed by the biforked part 42a is connected between the payout mechanism 31c at the lateral center side of a traveling machine body out of the distribution supply pipe 43 and a region in which the left-side payout mechanism 31a and the granular body send-out part 38 are connected to each other. A right discharge port 42c possessed by the biforked part 42a is connected between the payout mechanism 31c at the lateral center side of the traveling machine body out of the distribution supply pipe 43 and a region in which the right-side payout mechanism 31b and the granular body send-out part 38 are connected to each other. |
