The receiving trough 16 is provided in the rotary cylinder 14 in its full longitudinal direction, and a finished rice conveyor 17 is installed horizontally on the bottom surface of the receiving trough 16. A take-out port 19 is formed at the end of the discharge side 18 of the finished rice receiving trough 16, and the lower end of the take-out port 19 communicates with the top of the finished rice take-out trough 20.

21 is a finished rice take-out conveyor provided on the finished rice take-out gutter 20.

The cross-sectional structure of the finished rice receiving gutter 16 is as shown in FIG. The lower end of the regulating valve 23 is fixed to a shaft 24, and the angle of the regulating valve 23 is adjusted by rotating the shaft 24. A mixed rice recovery gutter 25 is installed in parallel on the side of the rotation rising side 22 of the finished rice receiving gutter 16, and a mixed rice spiral 26 is installed horizontally within the mixed rice recovery gutter 25. Reference numeral 27 denotes a feed gutter for mixed rice supplied by a thrower 41 to be described later, and a mixed rice feed spiral 28 is provided in the mixed rice feeder 27. 29 is a drop-off port.

Thus, a layer thickness detection sensor 31 is provided on the rotation rising side 22 of the mixed rice recovery gutter 25 and moves up and down depending on the thickness of the flowing layer 30, and the upper end of the sensor 31 is fixed by a shaft 32. The shaft 32 traverses the inside of the rotary cylinder 14 directly in the case of FIG. 1, or via the bell crank 48 in the case of FIG. It is pivoted to an arm 47 provided on the rotation shaft 35 of the control valve 4. 36 is a balancer for returning the detection sensor. A grain delivery plate 37 is provided near the detection sensor 31 and closer to the discharge side 18. The grain delivery plate 37 is attached to the lower side of the mixed rice recovery gutter 25 as shown in FIG. send out. 38 is an intermediate shelf. Discharge side 18 of the rotary cylinder 14
A plurality of packets 39 are formed, and the unhulled rice on the discharge side 18 of the rotary cylinder 14 is fried to an upper position and flows into a chute 40 formed in the supply hopper 2. Therefore, a grain frying device is not required. Reference numeral 41 denotes a thrower installed on the side of the mixed rice receiving gutter 11, which opens onto a return hopper 42 provided on the side of the different grain sorting section 13, and the hopper 42 opens onto the mixed rice supply gutter 27. do. 43 is a finished rice thrower provided on the side of the finished rice take-out gutter 20.

Thus, one end of the rotating shaft 35 becomes a crank g644, and a handle 4 that forms a handle 46 at the end of the crank part 44
6 to close the refill control valve 4, the retaining part 45 is attached near it so that its position can be fixed. Further, in FIG. 5, reference numeral 49 denotes a rotation sensor, and the rotation sensor 49 is located inside the collar 50 of the horizontally rotating cylinder 14. 51 indicates the distance that the rotation sensor 49 has entered inside the collar 50.

color range Next, we will discuss the effect.

When unhulled rice is supplied to the supply hopper 2 of the hulling section 1, the amount of unloaded rice is automatically adjusted by the loading control valve 4, and the unhulled rice is supplied to the hulling rolls 5.5, where it is hulled and falls into the wind sorting section 6. The rice husks are discharged from the exhaust pipe 8 by the suction air of the suction blower 7, and the immature rice falls into the immature rice receiving trough 12 and is taken out from the immature rice conveyor IO. The mixed rice falls into the mixed rice receiving trough 11, is taken out by the mixed rice conveyor 9, is fried in the hopper 42 by the thrower 41, is supplied from the hoe 2 par 42 to the mixed rice supply trough 27, and is fed to the mixed rice supply spiral 28. and falls into the horizontal shaft rotating cylinder 14 through the drop port 29. Since the horizontal shaft rotating cylinder 14 is rotating clockwise in FIG. 2, the grains form a sedimentary layer 30 and are shifted toward the rotation rising side 22, and the brown rice in the lower layer is pulled up through the pot hole 15 and sent to the finished rice receiving trough 16. The finished rice is taken out, transferred to the discharge side 18 by the finished rice conveyor 17, falls into the finished rice take-out gutter 20 from the take-out port 19, is transported horizontally by the finished rice take-out conveyor 21, and is taken out by the finished rice thrower 43.
After the unhulled rice remaining in the horizontal shaft rotating cylinder 14 is moved in the same way,
It is scooped up by a packet 39 formed on the discharge side 18 of the horizontally rotating cylinder 14, falls into a chute 40, and is returned to the supply hopper 2' for reprocessing.

As this work continues, the thickness of the sediment layer 30 may gradually increase, and the detection sensor 31 is pushed up by the sediment layer 30, rotates the shaft 32, and connects the replenishment control valve 4 via the rotation shaft 35. is moved in the closing direction to reduce the amount of hulling removed by the hulling section l.

However, the degree of opening and closing of the charge control valve 4 and the degree of detection by the layer thickness detection sensor 31 may not match accurately, and in such a case, the charge control valve 4 should be closed. In this case, when the handle 46 is held and the refill adjustment valve 4 is rotated in the closing direction, the refill adjustment valve 4 is closed, and at the same time, the crank portion 44 engages with the engagement portion 45 to maintain the closed state. , it can be assembled and adjusted.

In the conventionally known device, since the layer thickness detection sensor 31 and the charge adjustment valve 4 are linked, the charge control valve 4 cannot be closed independently, which is inconvenient during assembly and adjustment.

The present invention provides a finished rice receiving trough 16 inside a horizontally rotating cylinder 14 having a pot hole 15 formed in the inner surface, and a device for sorting the brown rice scooped up through the pot hole 15 by taking it out to the finished rice receiving trough 16. A detection sensor 31 for contacting the flow stack 30 and detecting the thickness of the flow stack 30 is provided in the rotary cylinder 14, and the detection sensor 31 is connected to the feed control valve 4 of the hulling section l. In the device that automatically adjusts the amount of feed, since the feed control valve 4 has a manual operating body on the shaft to adjust the feed amount control valve in the hulling device, the feed control valve 4 can be manually operated independently. Since it can be closed at any time, it is not only easy to assemble and adjust it, but also because the handle 46 is attached to the rotating shaft 35 of the refill control valve 4, the above object can be achieved with the simplest structure.
