The front end 21 </ b> A is capable of scooping the grains C near the bottom plate B <b> 2 by using the inclination and guiding it to the guide surface 30.

  As the support plate 22 rotates the rotary shaft 20, the front end 22A of the support plate 22 uses the inclination to scoop the grains C near the bottom plate B2, and guides it to the rear end 22B. The grains C are moved upward from the rear end 22B rather than the vicinity of the bottom plate B2.

  That is, the support plates 21 and 22 can move the cereal C upward from the vicinity of the bottom plate B2, and the position of the cereal C can be set to a position facing the guide surface 30. Further, it is possible to efficiently guide the grain C near the bottom plate B2 to the guide surface 30.

  According to the above grain agitation apparatus A, since the grains C accommodated in the flat stationary dryer B can be stirred so as to efficiently turn up and down, the flat stationary dryer B with respect to the grains C The warm air can be applied uniformly. Therefore, the drying efficiency of the grains C accommodated in the flat stationary dryer B can be improved.

  Further, since the stirring blade 3 moves the grains C accommodated in the flat stationary dryer B from the lower side by the power rotation in one direction of the rotary shaft 20, the conventional grains such as a scoop is used. Compared to C agitation / reversing work, the labor burden of the agitation / reversing work for cereal C can be reduced, and damage caused by contact of cereal C, container B1, etc. during agitation / reversing work for cereal C with scoop etc. Can be prevented.

  Moreover, the cereal C and the container B1 during the agitation / turnover operation of the cereal C are performed by the arc of the outer peripheral edge 30A of the guide surface 30, the arc of the outer peripheral edge 40 of the annular body 4, and the spherical portion 2A at the tip of the rotating shaft 20. It is possible to prevent damage due to contact.

  Furthermore, even if the annular body 4 is disposed above the tip of the spherical surface portion 2A and the rotating shaft 20 is tilted in a state where the spherical surface portion 2A is in contact with the bottom plate B2, the annular body 4 is not in contact with the bottom plate B2. Or since it can make it difficult to contact, the damage by contact of the grain C, the container B1, etc. at the time of the stirring and turning-over of the grain C can be prevented.

  Therefore, it is possible to prevent a drop in the grade of the cereal C due to damage or breakage, and to reduce maintenance costs due to damage or breakage of the container B1 or the like.
