PURPOSE:To prevent a carrier trough from deformation due to corn pressure in a corn storage tank having a funnel trough on the lower portion by forming on the front wall side of funnel an inclined wall inclined to approach the rear wall side as it extends downward. CONSTITUTION:A funnel 8 on the lower portion of a storage tank 3 is formed with a carrier trough 10 on the upper surface of which is journalled a conveyer 11. Also, the rear wall 6 of funnel 8 is formed with a vertical wall 12 while the lower portion of front wall 5 side is formed with a slant wall 13 approaching the rear wall 6 side as it extends downward, i.e. a distance between bearings 17, 18 for a shaft 14 of conveyer 11 is shortened. Thus, when corn is dumped into the storage tank 3 and the funnel 8 and carrier trough 10 are filled with corn, corn pressure to the conveyer 1 is reduced. Thus, the conveyer 11 on the carrier trough 10 is not deformed by the corn pressure.
