(Operation) Next, the operation will be described.

When the hulling section 1 is driven by a motor provided at an arbitrary position, the hulling roll 3 in the hulling section 1 is rotated, and the hulling section 1 is also rotated.
The output shaft 42 attached to the counter 41 provided on the input shaft 37 rotates, and the input shaft 37 is connected to the output shaft 42 via the coil spring 43, so that the input shaft 37 rotates.

When the input shaft 37 rotates, the variable pulley 38 and the respective passive pulleys 47, 48, 49 and 50 are rotated by the belt 53, and the respective spiral or roll shafts are rotated.

Then, when paddy rice is supplied to the stake hopper 2, the paddy rice is hulled by the hulling roll 3 and dropped to the wind sorting section 4, the hulled rice is wind-sorted, the mixed rice falls to the mixed rice receiving trough 8, and the immature rice. Fall into the immature rice gutter 9. The mixed rice dropped on the mixed rice receiving trough 8 is fed laterally by the mixed rice conveyor 6 into the inside of the thrower 58, and is raised to be supplied to the hopper 59. Since the hopper 59 is opened to the supply gutter 35, the hopper 59 is conveyed to the dropping cylinder 60 at the end by the supply spiral 36 and supplied into the horizontal axis rotary grain selection cylinder 23.

Then, since the horizontal axis rotary grain selection cylinder 23 is rotating, the mixed rice is stacked down as it is rotated, and is shifted toward the rotation rising side 30 side. Since the lower layer of the descending stack is brown rice, the grain that fits into the pot hole 24 is brown rice, and as the horizontal axis rotary grain selection cylinder 23 rotates, it rises and is taken out to the finished rice receiving gutter 25. Is sent to the exit 27 side, and the exit 27
It falls inside and is taken out from the finished rice taking-out gutter 28 through the finished rice taking-out conveyor 29.

Therefore, when the amount of grains supplied to the horizontal axis rotary grain selection cylinder 23 decreases, or when the sorting efficiency of the rotary grain selection cylinder 23 on the side of the falling cylinder 60 is high, or when the rotary grain selection cylinder 23 remains in the rotary grain selection cylinder 23, For the processing of rice or the like, when the rotating lever 17 is operated and the tilt adjusting device 13 moves the falling grain 60 side of the rotary grain selecting cylinder 23 upward, this upward movement causes the horizontal axis rotary grain selecting cylinder. The grain supplied into the inside 23 moves to the outlet 27 side and the thickness of the descending stacking is increased to properly select the mixed rice, or the rotary grain selecting cylinder 2
The residual rice in 3 is discharged.

In this way, even if the inclination adjusting device 13 adjusts the inclination of the rotary grain selection cylinder 23 side with respect to the hull portion 1 side, the rotary grain selection cylinder 23
Side input shaft 37 is an output shaft 42 provided on the side of the hull portion 1.
Since it is connected via the coil spring 43,
The rotary grain selection cylinder 23 can freely transmit power to the slope of the hull portion 1.

When the belt 53 is replaced, the coil spring 43 is removed from the disc 44 and the disc 45 to form a gap between the input shaft 37 and the output shaft 42, and the belt 5 is inserted through the gap.
Remove 3.

(Effect) In a conventionally known hulling device, a hulling unit having a hulling roll axially mounted on a left-right axis at an upper position in the front-rear direction of a wind-selecting unit, which is long in the front-rear direction, is provided in front of the wind-selecting unit. It is known that a heterogeneous mixed rice grain selecting device having a horizontal axis rotating grain selecting cylinder of a longitudinal axis is attached at a side upper position, and the horizontal axis rotating grain selecting cylinder is provided so that its inclination angle can be adjusted.

However, the horizontal axis rotary grain selection cylinder of the known hulling device is rotated by a complicated power transmission mechanism.

However, according to the present invention, the hulling section 1 having the hulling roll 3 axially mounted on the left-right axis at a position above and behind the wind selecting section 4 which is long in the front-rear direction is provided on the other side of the wind selecting section 4. The heterogeneous mixed rice grain selecting device 10 having the horizontal axis rotating grain selecting cylinder 23 of the longitudinal axis is attached to the upper position, and the horizontal axis rotating grain selecting cylinder 23 is provided so that the inclination angle can be adjusted, and the horizontal axis rotating grain selecting cylinder is also provided. The 23-side input shaft 37 is connected to the front-rear output shaft 42 protruding from the hull portion 1 side to receive power transmission.
In addition, since it is used as a transmission device of a pothole type rotary grain selecting device of a hulling device in which a coil spring 43 is interposed at a connecting portion between the output shaft 42 and the input shaft 37, it is possible to rotate the horizontal shaft. Since the input shaft 37 on the grain selection cylinder 23 side is connected to the output shaft 42 in the front-rear direction protruding from the hulling portion 1 side to receive power transmission, the hulling roll 3 is provided on the hulling portion 1 side. Since a gear box for rotating is naturally provided, it is easy to project the output shaft 42 in the front-rear direction from the side of the hull portion 1, and therefore, the power transmission mechanism of the heterogeneous mixed rice grain selection device 10 is remarkably high. It is simple and easy to handle.

In addition, since the coil spring 43 is interposed at the connecting portion between the output shaft 42 and the input shaft 37, even if the input shaft 37 bends by adjusting the heterogeneous mixed rice grain sorting device 10 side, it is smooth. Power can be transmitted to.

Has the effect.
