GRAIN CIRCULATION STRUCTURE OF GRAIN DRYING MACHINE

PROBLEM TO BE SOLVED: To reduce noise by grain to improve drying work by checking a flow of a part of the grain discharged from a delivery valve and dropping during drying operation of the grain by a grain piling-up means of the upper face of a grain flowing trough to let the grain temporarily pile up on the grain piling-up means, and letting the grain further drop on the upper face of the grain let to pile up by the grain piling-up means to prevent direct abutment of the grain on the upper face of the grain flowing trough, in a grain circulation structure of a grain drying machine. SOLUTION: The grain piling-up means letting the part of the dropped grain pile up is provided on the upper face of the grain flowing trough in a portion on which the grain discharged from the delivery valve drops.
