Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hulling control device for separating and removing paddy from brown rice and rice husk by a pair of derolling or the like.

[Prior Art] Conventionally, there has been a technique in which hulling work is performed by automatic control, and when an abnormality occurs in the automatic control, an alarm is output by an error output and the automatic control is stopped.

“Problems to be solved by the invention” In the above-mentioned conventional technology, when the operator cannot scratch the alarm due to the error output, the hulling work is continuously performed even if the automatic control is stopped. However, there were safety problems such as the cause of the problem was aggravated and the damage was expanded.

"Means for Solving the Problems" However, the present invention is a hulling section that is driven by a hulling drive member to remove the hull, and a supply shutter that controls the hull supply to the hulling section. In a hulling control device provided with an opening / closing member for opening and closing the shutter, and provided with a reset button for automatically resetting an error output from the automatic control unit for automatically performing paddy sliding operation, the error output of the automatic control unit is The supply shutter is automatically closed when the supply shutter is continuously operated for a predetermined time or more, and the hulling drive member is automatically operated when the error output from the automatic control unit is continued for a predetermined time or more even after the supply shutter is closed. It is characterized in that it is configured to stop automatically.

[Operation] Therefore, when the reset button is not operated within a certain time from the error output, the supply shutter is closed, so that damage expansion of the hull portion can be easily prevented, and after the supply shutter is closed. When the error output continues for a certain period of time or more, the hulling drive member is stopped.
It is possible to prevent the abnormal state from being left unattended, and it is possible to easily improve safety and handling operability as compared with the conventional case.
