Further, as disclosed in Japanese Patent Laid-Open No. 61-50681, there is a technique of detecting the amount of mixed rice in the sorting cylinder and adjusting the inclination angle of the sorting cylinder. Further, as disclosed in Japanese Utility Model Laid-Open No. 60-179384, there is a technique for detecting the position of a sluice valve that receives finished rice in a gutter and switching the shunt valve to operate the shunt valve on the in-body circulation side or the unloading side. is there.

[Problems to be Solved by the Invention] In the prior art, the sensor for detecting the mixed rice in the selection drum has a problem of impeding the flow of the mixed rice to reduce the selection efficiency, and also processing the paddy with many branch prickles. When doing so, there is a problem that the amount of paddy taken into the derolling fluctuates, the amount of rice grains fed to the sorting cylinder tends to be insufficient, and the sorting operation is carried out in an unstable manner.

"Means for Solving the Problem" Therefore, the present invention includes a paddy rice portion and a sorting portion, and a paddy rice valve for adjusting the paddy feed amount to the derolling roll, and a feed adjusting member for opening and closing the paddy rice valve. A sorting cylinder that is provided in the hulling portion and separates and sorts the finished rice; a rotating member that rotates the sorting cylinder so that the number of rotations can be adjusted; and a finishing rice that is installed in the sorting cylinder and separated by the sorting cylinder. Receiving gutter, a sluice valve for changing the amount of finished rice received in the sluice, a sluice adjusting member for adjusting the opening degree of the sluice valve, and a gutter from the sorting cylinder at the sorting start side and the terminating side of the sorting cylinder. The inlet side and outlet side receiving amount sensors for detecting the finished rice received by, the inclination adjusting member for adjusting the inclination of the sorting cylinder in the axial direction, and the taking-out direction of the finished rice sent from the gutter to the in-cylinder circulation side or Change the picking direction switching member to switch the finishing rice picking shutter to the outside of the machine. In the paddy sorting device provided in the sorting unit, the supply adjusting member, the rotating member, the partition adjusting member, the inclination adjusting member, and the take-out direction switching member are detected by the receiving sensors on the inlet side and the outlet side. The present invention is characterized in that a controller is provided for automatically relating and controlling based on the result.

“Working” Therefore, the rice to be sorted inside the sorting cylinder is not obstructed from flowing, the movement of the rice to be sorted can be appropriately maintained, and the sorting efficiency of the sorting cylinder can be easily improved. Since the above-mentioned members are automatically controlled in association with each other on the basis of the amount of finished rice detected by the quantity sensor on the outlet side and the difference between them, it is possible to increase / decrease the amount of rice to be sorted in the sorting cylinder and increase / decrease the processing amount of derolling. It is possible to maintain the amount of finished rice received on the inlet side and the outlet side of the gutter as quickly as possible, and to easily perform a stable sorting operation even for paddy treatment with many branch pruning, where the amount taken into the derolling tends to fluctuate easily. In addition, it is possible to compensate for the shortage with each other by the related control of each member, and to simplify the control structure of each member and easily improve the hulling and sorting function.
