Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paddy supply regulating device for a husking section that husks chaff from paddy.

[Prior art]

In the prior art paddy supply adjustment device for the husking section, a single paddy supply adjustment plate is rotatably supported below the paddy tank of the husking section, and the paddy is supplied from the paddy tank to the husking chamber below. The amount was to be adjusted. Therefore, in order to prevent grains from leaking between the paddy supply adjustment plate and the hulling chamber side wall, it is necessary to create a small gap between the paddy supply adjustment plate and the hulling chamber side wall.
For this reason, when adjusting this paddy supply adjustment plate according to the grain amount in the mixed rice sorting section, if grains are caught between the paddy supply adjustment plate and the side wall of the husking chamber, the paddy will be removed. There was a problem in that the automatic rotation adjustment of the supply adjustment plate did not proceed smoothly.
