Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing contamination of unhulled rice in a pot-hole type grain sorting device in a hulling device.

Conventionally, some rice hulling devices are equipped with a rotary type mixed rice sorting device. This grain sorting device feeds a mixed rice mixture into a rotary cylinder with numerous pot holes formed on its inner surface and rotates it, and the finished rice (brown rice) in the lower layer is pulled up through the pot holes and the finished rice is placed inside the rotary tube. The mechanism is to take it out into the gutter.

The condition of this grain sorting device is that the amount of mixed rice supplied to the rotary tube is constant. but,
When the amount of unhulled rice supplied to the hulling section decreases, the amount of mixed rice supplied to the rotating cylinder becomes less than the fixed quantity, and the rotational load of the rotating cylinder increases due to the lack of grain weight in the rotating cylinder. As the rotation speed increases, unhulled rice gets mixed into the finished rice. This phenomenon is
This also occurs when the amount of hulled material stored in the hopper of the hulling section decreases. When the unhulled rice runs out and the hulling operation ends, the amount of mixed rice supplied into the rotary cylinder decreases and becomes so-called residual rice, which cannot be sorted.

Therefore, the present invention detects the amount of unhulled rice supplied to the huller, controls the rotation speed of the rotary cylinder, and also controls the horizontal angle of the rotary cylinder to dispose of residual rice in the rotary cylinder. A rice hulling section 1 having a tensioning hopper 2 is formed, a dissimilar grain sorting section 12 is provided on the side of the hulling section 1, and a dissimilar grain sorting section 12 is provided on the side of the hulling section 1.

A dissimilar grain sorting section 12 is provided on the side of the hulling section 1. A case 13 of the sorting section 12 is provided to be placed on the machine body, the lower end of the case 13 on the side of the hulling section 1 is rotatably attached to a shaft 14, and the lower end of the other end of the case 13 is attached to the sensor. It is attached via the inclination adjustment device 15 in conjunction with 41. That is,
When the tilt adjustment device 15 is actuated by the sensor 41, the case 13 moves up and down about the shaft 14 with respect to the aircraft body, and the horizontal angle of the case 13 is adjusted.
The inclination adjustment device 15 includes a shaft 16 that is rotatably attached to the body side, a shaft 17 that is attached to the case 13 and moves up and down together with the case 13, and an arm that connects the shaft 16 and the shaft 17. 18 and
It is composed of a motor 19. Opposite gear grooves 20 and 20a are formed on the left and right sides of the shaft 16, respectively, and the arm 1 is inserted into the gear grooves 20 and 20a.
A screw tube 21 which is fixed to the lower ends of the screws 8 and 18 is screwed together. The upper ends of the arms 18, 18 are fixed to the shaft 17 in the axial direction, and are freely rotatable. The shaft of motor 19 is connected to shaft 16 .

Inside the sorting section 12, a horizontal rotating cylinder 22 is installed horizontally on a pair of rotating rolls 42, 42, and is fixed to a pulley fixed to the shaft of the rotating roll 42 and a rotating shaft of a motor 43 provided on the machine body side. A belt 44 is passed between the pulley and the pulley. A motor 43 is provided in conjunction with the sensor 40. Numerous potholes 23 are formed on the inner circumferential surface of the horizontal rotating cylinder 22. A finished rice receiving trough 24 is formed within the rotary cylinder 22. The receiving gutter 24 is provided completely in the longitudinal direction inside the dissimilar grain sorting section 12, and the finished rice conveyor 2 is installed on the bottom surface of the receiving gutter 24.
5 is installed horizontally. Discharge side 2 of finished rice catcher 24
An outlet 27 is formed at the end of 6.
The lower end opens above the finished rice take-out gutter 28. 29 is a conveyor for taking out finished rice.

A finished rice control valve 31 is attached to the rotation rising side 30 of the finished rice receiving trough 24. The lower end of the control valve 31 is connected to the shaft 3.
2 and by rotating the shaft 32, the angle of the regulating valve 31 is adjusted.

A supply gutter 34 is installed in parallel on the descending side 33 of the finished rice receiving gutter 24. A supply spiral 35 is provided within the supply trough 34 . A thrower 3 is installed on the side of the mixed rice conveyor 8.
6 is attached, the thrower 36 opens into a hopper 37 fixed to the end of the dissimilar grain sorting section 12, and the hopper 37 opens onto the supply gutter 34. 38 is a drop tube, and 39 is a current plate.

Next, we will discuss the effect.

When the unhulled rice is supplied to the chucking hopper 2, it is hulled by the hulling rolls 3, 3 and falls into the wind sorting section 5, the unhulled rice is sucked by the suction blower 6, and the mixed rice falls into the mixed rice receiving trough 10. , the immature rice falls into the immature rice receiving trough 11. The mixed rice that has fallen into the mixed rice receiving trough 10 is conveyed horizontally by the mixed rice conveyor 8 and flows into the thrower 36, which is then raised and supplied to the hopper 37. Since the hopper 37 is open to the supply gutter 34, it is sent to the falling tube 38 by the supply spiral 35 and is sent to the horizontal axis rotating tube 2.
Supplied within 2 days.

Since the horizontal shaft rotating cylinder 22 is rotating, the mixed rice becomes a descending layer as it rotates, and is biased toward the rotating upward side 30. Since the lower layer of the falling layer is brown rice, the grain that fits into the pot hole 23 is brown rice, which rises as the horizontal rotating cylinder 22 rotates, is taken out to the finished rice receiving trough 24, and is discharged by the finished rice conveyor 25. The rice moves to the side 26 and falls through the take-out port 27, and is taken out from the finished rice take-out gutter 28 via the finished rice take-out conveyor 29.

However, if the amount of unhulled rice supplied to the hopper 2 decreases and the unhulled rice stored in the hopper 2 becomes less than sensor 40, the amount of hulled rice will decrease.
The supply amount in the horizontal shaft rotating cylinder 22 decreases and the rotational load becomes lighter, which increases the rotational speed and causes poor sorting.However, in the present invention, the sensor 40 turns on and the rotational speed of the motor 43 is controlled. , horizontal shaft rotating cylinder 22
The rotation speed of the machine is slowed down to improve the accuracy of the sorting process and prevent the contamination of unhulled rice. When the supply of unhulled rice further decreases, the sensor 41 turns ON, the motor 19 rotates, the shaft 16 rotates, and the arm 18
is moved in the vertical direction, the supply side 45 of the different grain sorting section 12 is moved upward, and the mixed rice is delivered to the discharge side 26.

As described above, the present invention forms a hulling section 1 having a hopper 2, a dissimilar grain sorting section 12 is provided on the side of the hulling section 1, and the dissimilar grain sorting section 12 is provided with a pot hole type. In a horizontally installed horizontal shaft rotary cylinder 11 for sorting grains, the lower part of one side of the case 13 of the different grain sorting section 12 is rotatably attached to the machine body side by a horizontal shaft, and the lower part of the other side of the case 13 is rotatably attached to the machine body side by a horizontal shaft. A tilt adjustment device 15 capable of adjusting the horizontal angle is provided, and the hopper 2
A sensor 40 that is activated when the stored amount of unhulled rice is below a certain level and a sensor 41 that is activated when the amount is further decreased are provided in the interior.
Since the rotation motor 43 is configured as a device for preventing contamination of paddy and rice in a pot-hole type grain sorting device in a hulling device in which the sensor 41 and the inclination adjustment device 15 are respectively provided in conjunction with each other, Since the rotation speed can be maintained constant even when the load changes, it is possible to prevent unhulled rice from getting mixed into the finished rice.

(b) The mixed rice remaining in the horizontal rotating cylinder 22 can be quickly discharged.
