RETURNING DEVICE FOR GRAIN IN RICE HUSKING AND SORTING MACHINE

摘要

PURPOSE:To easily treat the clogged grains by returning the grains discharged from a rotary sorting cylinder to a husking part by a paddy receiving gutter and a paddy elevator, and guiding the grains accumulated in the vicinity of the paddy receiving gutter to the receiving gutter of husked rice without winnower of a wind sorting part. CONSTITUTION:When clogging phenomena are caused in a paddy elevator 22 during rice husking and sorting work, grains discharged from a rotary sorting cylinder 1 flow down to a paddy receiving gutter 21 and are successively accumulated. The accumulated grains reach the upper end part of a guide apparatus 21, constituted into a gutter shape. In such a way, the accumulated grains are introduced into the guide apparatus 24 and flow down and are guided to a receiving gutter 7 of husked rice without winnower in a wind sorting part C. These accumulated grains are elevated and circulated to the rotary sorting cylinder 11 or discharged to the outside of machine from a blended rice elevator 8 by changing over a grain elevation port part in the direction of takeout to the outside of machine. Accordingly grains are prevented from being overflowed from the connection part of the rotary sorting cylinder 11 and the paddy receiving gutter 21. Treatment of the clogged grains is simplified.
