PURPOSE:To properly prevent both stains from sticking inside a box-shaped frame and rice grains from remaining on the bottom thereof, by attaching a cleaner, which is operated by a magnet, to a key position of a bucket belt so as to clean up the inside of a grain lifter quickly. CONSTITUTION:When the inside of a grain lifter is to be cleaned, an electromagnet 8 is electrified to start a cleaner. Then a bucket belt 5 is circulated, until a swing lever 14, which is installed to a rotary shaft 10 of a rotating mechanism 7, is positioned face-to-face with respect to an electromagnet 8 placed on a surface of a box-shaped frame 1. Magnet force of the electromagnet 8 induces the rotation of the swing lever 14. As a result, a supporting shaft 11, which is planted on this swing lever 14, is rotated within a lateral guide shaft 12 while it is moving in the transverse direction, thereby erecting a cleaner 6. Both thus erected cleaner 6 and a bucket 4 are rotated in a machine frame. With this contrivance, both stains sticking to the inside of the box-shaped frame 1 and rice grains remaining on the bottom of the frame 1 can be cleaned with this cleaner 6 and can be put into the bucket 4 so that they are discharged eventually from the frame 1. |
