PROBLEM TO BE SOLVED: To provide an adjustment device carrying out restriction of unhulled rice feed rate during circulation of unpolished rice in a machine with more simple structure as compared with the conventional ones by an inexpensive mechanism in an unhulled rice husking sorting machine comprising an unhulled rice husking part A for husking the unhulled rice, a husking falling rice wind sorting part B for wind-sorting husking falling rice from the unhulled rice husking part A, a rocking sorting device 20 type mixed rice sorting part C for sorting mixed rice of the unhulled rice and unpolished rice and a shell conveying part D, and having a unhulled rice feed valve 8 provided above husking rolls 9, 10 of the unhulled rice husking part A and a directional control valve 33 for circulating unpolished rice taken out from the rocking sorting device 20 constituting the mixed rice sorting part C in the machine and taking out it outside the machine. SOLUTION: A check mechanism 109 for not-opening the unhulled rice feed valve 8 at a set opening degree or more when the directional control valve 33 is switched to circulation side in machine and wholly opening the unhulled rice feed valve 8 when the directional control valve 33 is switched to the taking out side outside the machine; and an operation lever 92 for switching the directional control valve 33 to the circulation side in the machine or the taking out side outside the machine are provided. The check mechanism 109 is constituted such that it is interlocked with the operation lever 92 of the directional control valve 33 to switch the check state or the check release state.
