PURPOSE:To prevent the piled seeding boxes from being shifted or thrown down by receiving the transported seeding boxes by receiving bodies and transporting said seeding boxes onto the seeding box loading receiving frames and then piling said seeding boxes by removing the receiving bodies, in the automatic piling device for the seeding boxes. CONSTITUTION:The captioned device is equipped with stopper devices 29a and 29b which stop a seeding box 2 installed at a prescribed height, at a certain position, on the side of transfer direction of a transfer device 16 for transporting the seeding box 2. In the lower part of the seeding box 2 which is stopped by the stopper devices 29a and 29b, receiving bodies 26a and 26b are installed in switching between the seeding box receiving state and non-receiving state, and seeding box loading receiving frames 40 and 41 are installed in the lower parts of the receiving bodies 26a and 26b so as to be intermittently lowered by the vertical width of the seeding box 2. The receiving bodies 26a and 26b are switched from the seeding box receiving state to the non-receiving state by the signals of the switches 31a and 31b which act when the seeding box 2 is received by the stopper devices 29a and 29b. Then, the seeding box loading receiving frames 40 and 41 are lowered.
