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, rice hulling equipment has been equipped with a mixed rice sorting equipment using a rotary set. This grain sorting device feeds a mixed rice mixture into a rotary cylinder with numerous potholes formed on its inner surface, rotates it, and pulls out the finished rice (brown rice) in the lower layer.
This mechanism takes out the finished rice into a receiving trough provided in the rotation 1; z).

The condition of this grain sorting device is that the amount of mixed rice supplied to the rotary tube is constant. However, when the amount of unhulled rice supplied to the hulling section decreases, the amount of mixed rice supplied into the rotating cylinder remains constant. Due to the lack of grain weight in the rotary cylinder, the rotational load on the rotary cylinder decreases and the rotational speed becomes faster, resulting in unhulled rice being mixed into the finished rice. This phenomenon also occurs when the amount of hulled material stored in the hopper of the hulling section begins to decrease. When the unhulled rice runs out and the hulling operation ends, the amount of mixed rice fed into the rotary tube decreases, resulting in so-called residual rice that cannot be sorted.

Therefore, the present invention detects the amount of unhulled rice supplied to the huller, controls the rotation speed of the rotating barrel (51), and also controls the horizontal angle of the rotating barrel to dispose of residual rice in the rotating barrel. The purpose of this system is to form a hulling section 1 with a staked hopper 2, provide a dissimilar grain sorting section 12 on the side of the hulling section 1, and install a pot-hole type sorter in the dissimilar grain sorting section 12. Horizontal shaft rotating cylinder 1 for grain harvesting

The lower end of the case 13 on the hulling section 1 side is rotatably attached to the shaft 14, and the lower end of the case 13 on the other end side is attached via the inclination adjustment device 15 linked to the sensor 41.

That is, when the tilt adjustment device 15 is activated 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 is attached to the body side so that it can only rotate freely.
III116 and the case 13 attached to the case 13
It is composed of a support 17 that is raised together with the shaft, an arm 18 that connects the shafts 16 and 17, and a motor 19. The shaft 16 has opposite gear grooves 20.20a on its left and right sides.
are respectively carved, and a screw tube 21 fixed to the lower end of the arm 18.18 is screwed into the gear groove 20.20a. The upper end of the arm 18.18 is fixed to the shaft 17 in the axial direction, and rotation is freely stopped. The axis of motor 19 is iI! Connect to 1II16.

Inside the sorting ya+ 12, a horizontal shaft rotating cylinder 22 is placed horizontally on a pair of rotating rolls 42, 42, and a pulley fixed to the body of the rotating rolls 42 and a motor 43 provided on the machine body side.
A belt 44 is hooked between the belt 44 and a pulley fixed to the rotating shaft of the belt 44, and the belt 44 is rotated. A motor 43 is provided in conjunction with the sensor 40. Numerous pot holes 2 are formed on the inner peripheral surface of the horizontal shaft rotating cylinder 22.
form 3. A finished rice receiving trough 24 is formed within the rotary cylinder 22. The receiving trough 24 is provided throughout the lengthwise direction of the different grain sorting section 12, and a finished rice conveyor 25 is installed horizontally on the bottom surface of the receiving trough 24. A take-out port 27 is formed at the end of the υF outlet side 26 of the finished rice receiving trough 24, and the lower end of the take-out 27 opens into the finished rice take-out trough 28''. 29 is a conveyor for taking out finished rice.

Install. The end of the control valve 31 is fixed to a shaft 32, and the angle of the control valve 31 can be adjusted by rotating the shaft 32.
do.

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 36 is attached to the side of the Konkin conveyor 8, and the thrower 36 is attached to the hopper 3 disposed around the end of the dissimilar grain sorting section 12.
7 and the hopper 37 opens onto the supply trough 34.

38 is falling oil, and 39 is a rectifying plate.

Next, we will discuss the effect.

When unhulled rice is supplied to the stake hopper 2, the hulling roll 3.3
The rice husks are removed by a suction blower 6, and the rice husks are removed by a suction blower 6.
The four-kong rice is sucked into the mixed rice receiving trough 10, and the immature rice falls into the immature rice receiving trough 11. The mixed rice fell into the mixed rice receiving trough 10 and was transported sideways by the mixed rice container hair 8 made of mixed rice and thrown into the thrower.
The liquid flows into the hopper 36, rises and is supplied to the hopper 37. Since the hopper 37 is open to the supply gutter 34, it is sent to the drop tube 38 by the supply spiral 35 and supplied into the horizontally rotating tube 22.

Since the horizontal shaft rotating cylinder 22 is rotating, the l hanger material becomes a descending layer as it rotates, and is tilted 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 in the take-out column 27, and is taken out from the finished rice take-out gutter 28 via the finished rice take-out conveyor 29.

However, when the amount of unhulled rice supplied to the hopper 2 decreases and the unhulled rice stored in the hopper 2 becomes less than the sensor 40, the amount of hulling decreases, so the hot water supplied in the horizontal shaft rotating cylinder 22 decreases. The rotational load decreases and the rotational load becomes lighter, which causes the rotational speed to increase and result in poor sorting.However, in the present invention, the sensor 40 is turned ON and the rotational speed of the motor 43 is controlled, so that tIIJ
The shaft-rotating shaft-rotating tube mouth 2 is made difficult to improve the accuracy of sorting work and prevent unpaddy rice from being mixed in. When the supply amount of unhulled rice further decreases, the sensor 41 turns ON, the motor 19 rotates, rotates the shaft 16, moves the arm 18 in the vertical direction, and moves the supply side 45 of the dissimilar grain sorting section 12 upward. hand,
The lfL alloy metal comes out on the discharge side 26.

As described above, the present invention provides a method for handling paddy
'; A part l is formed, and a dissimilar grain sorting part 1 is formed on the side of the hulling part l.
2 is provided, and a horizontal shaft rotating cylinder 11 for performing pot-hole type centrifugation is installed horizontally in the dissimilar grain sorting section 12, and one side door portion of the case 13 of the dissimilar grain sorting section 12 is connected to a water shaft. A tilt adjustment device 15 is provided at the lower part of the other side of the case 13 to adjust the horizontal angle, and a sensor 40 is installed in the hopper 2 to be activated when the amount of unhulled rice stored is less than Ikki. and sensor 4, which activates when it decreases further.
1 is provided, and the sensor 40 and the rotation motor 43 of the horizontal shaft rotating cylinder 11 are connected to the sensor 41 and the inclination adjustment device 15.
Since the structure is configured as a device to prevent the mixing of paddy and rice in the pot-hole type grain sorting device in the hulling device installed in conjunction with each other, (a) the rotation speed can be kept constant even if the load on the horizontal shaft rotating cylinder 22 changes. Therefore, it is possible to prevent unladed rice from being mixed into the tithe rice.

The mixed rice remaining in the spout and horizontal axis rotating cylinder 22 can be quickly discharged.

C. The structure is simple.

This effect is achieved.
