PROBLEM TO BE SOLVED: To provide grain collecting chamber structure of a grain dryer in which operation power of a drying suction fan is reduced, while securing compact body structure of the grain dryer. SOLUTION: This grain collecting chamber structure of a grain dryer 1 comprises a burner 17, grain collecting plates 14, 14, a bottom spiral 15, and the like, and the grain collecting plates 14, 14 have double structure having a hollow part communicating with upper and lower parts of a inclination by combinedly installing bottom plates 14a, 14a. Openings d, d of the upper part of the inclination are communicated with outside air, and openings e, e of the lower part of the inclination are communicated with the grain collecting chamber c, to form outside air conduction passages g, g. The openings e, e of the lower part of the inclination face the bottom spiral 15, and are positioned higher than a transfer area of a transferring spiral 18. COPYRIGHT: (C)2003,JPO
