The drying unit 1b dries hot air or room temperature air while circulating and flowing by the operation of a grain circulation system such as the elevator 2 and the upper conveyor 15.

[0003] In this grain dryer A, while the grain harvester is turned off and stored in a storage house or the like, rats enter and leave the body a and cause rat harm. In many cases, the cause is that the grains remaining in the body a when the body a is housed enter as a suitable bait. Therefore, when the body a is housed, the kernels are stored in the body a. Clean so that there is no residue. However, the kernel remains in the corner formed between the lower end of the grain flow-down passages 11 of the drying section 1b and the peripheral wall of the shutter drum 13 provided so as to face the lower end. Therefore, it is difficult to discharge the remaining grains neatly even when the shutter drum 13 is operated idle. For this reason, in this corner, a gap W is formed on the bottom surface of the corner to positively open the gap, and the gap W is closed by a sealing member S that opens and closes and rotates.
When storing the machine body a, the gap W is opened so that the remaining grains are dropped downward.

At the time of the cleaning operation, the worker inserts the knock rod 40 for holding the support member 4 at a position where the seal member S thereof is in sliding contact with the peripheral surface of the shutter drum 13 and inserts the hand into the machine body a and upwards. By moving the support member 4 so as to slide, the support member 4 is freely rotated about the rotation shaft 3, and in this state, the operation unit provided at the shaft end of the rotation shaft 3 protruding from the outer surface of the body a is operated. Then, by repeatedly rotating the support member 4, the grains remaining in the corner formed by the lower end of the flow-down path 11 and the peripheral surface of the shutter drum 13 flow down cleanly, Aircraft a has almost no residual kernels So it can be cleaned.

However, even in this case, the rat enters and exits the fuselage a, and since the rat prefers a dark and narrow passage-like place, the nest nests near the seal member S at the lower end of the downflow passage 11. Therefore, there is a problem that the seal member S formed of a flexible material is bitten, and the seal member S is damaged by contamination or damage by manure.

The present invention has been made in order to solve the above-mentioned problem occurring in the conventional means, and is intended to solve the above problem.
