Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for adjusting the dehulling rate of a rice huller and a mixing rate of a pothole type grain sorting device.

When the mixed rice in the hulling device is sorted into different types of mixed rice using a pot-hole type grain sorting device, the dehulling rate A of the hulling section and the unsorted rice in the rotating cylinder are taken out again. The relationship between the mixing ratio B of the mixed rice that is circulated and supplied into the rotary cylinder is an important issue in terms of work efficiency. In other words, when the dehulling ratio A>mixing ratio B is established, the mixed rice discharged from the rotary cylinder has a large proportion of unhulled rice, so the amount of unpolished rice taken out is small, so the layering inside the rotary cylinder gradually increases. Therefore, continuous operation becomes impossible, and if the dehulling rate is A and the mixing rate is B, brown rice equal to (mixing rate B - dehulling rate A) is returned to the hulling section along with the reduced paddy rice and is hulled again. This results in so-called double printing, which increases the number of damaged rice, and only when the dehulling ratio A=mixing ratio B, there is no loss in the entire apparatus and efficient sorting work can be performed.

Therefore, the present invention aims to improve the dehulling rate A of the mixed rice that is hulled by the huller and supplied to the rotary tube, and the mixing rate of the mixed rice that is discharged from the rotary tube as unsorted rice and returned to the rotary tube again. B is compared and controlled so that they are the same, and the rice grains are A conveying device for supplying mixed rice to the different grain sorting section, and a mixed rice discharge gutter in the rotary cylinder of the different grain sorting section, wherein the hulling section has a dehulling rate A of the hulling section. A sensor is provided in the discharge flow path of the mixed rice discharge gutter to detect a mixing ratio B of the mixed rice taken out to the mixed rice discharge gutter, and a sensor is provided on the rotation rising side of the mixed rice discharge gutter. Dehulling rate and pot hole of a rice hulling device in which a mixed rice regulating valve is provided to be openable and closable, and the mixed rice regulating valve is adjusted by the sensor and the sensor so that the dehulling rate A and the mixing rate B are approximately the same.

A thrower 51 is attached to the side of the mixed rice conveyor 15, and the thrower 51 opens onto a hopper 52 fixed to the end of the dissimilar grain sorting section 18, and the hopper 52 opens onto the supply gutter 38. In the figure, 53 is a paddy rice receiving trough, 54 is a paddy rice conveyor, 55 is a paddy rice return thrower, and 156 is a current plate.

Next, we will discuss the effect.

When unhulled rice is supplied to the stake hopper 2, the hulling roll 5.5
The rice husks are removed from the rice and dropped into the wind sorting section 7 through the falling channel 9. The rice husks are sucked by the suction blower 13, the mixed rice falls into the mixed rice receiving trough 10, and the immature rice falls into the immature rice receiving trough 17. . Therefore, the mixed rice falling onto the mixed rice receiving trough 10 is placed on the guide plate 8.
When the rice flows down between the light source 11 and the light detection sensor 12 provided in the mixed rice receiving trough 10, the dehulling rate A is automatically measured. The mixed rice that has fallen into the mixed rice receiving trough 10 is conveyed horizontally by the mixed rice conveyor 15 and flows into the thrower 51, which is then raised and supplied to the hopper 52. Since the hopper 52 opens onto the supply gutter 38 , it is sent to the drop tube 40 by the supply spiral 39 and supplied into the horizontally rotating tube 19 .

Since the horizontal shaft rotating cylinder 19 is rotating, the mixed rice becomes a descending layer as it rotates, and is biased toward the rotating upward side 34. Since the lower layer of the falling layer is brown rice, the grain that fits into the pot hole 27 is brown rice, which rises as the horizontal shaft rotating cylinder 19 rotates and is taken out to the finished rice receiving trough 28, and is taken out by the finished rice conveyor 29.
The rice moves to the discharge side 30 and falls through the take-out port 31, and is taken out from the finished rice take-out gutter 32 via the finished rice take-out conveyor 33.

Thus, the mixed rice that cannot be sorted is taken out into the mixed rice discharge gutter 41, conveyed from the mixed rice discharge conveyor 42 to the discharge side 30, and falls onto the mixed rice receiving gutter 10 through the droplet opening 48.

However, since the drop port 48 is provided with a light source 49 and a light reception detection sensor 50 in a vertical relationship, the drop port 48
The mixing rate B of the mixed rice falling inside is measured, and the light source 1
1 and the light reception detection sensor 12.
The control device 46 compares the mixing rate B measured by the light source 49 and the light detection sensor 50, rotates the motor 47, adjusts the mixed rice control valve 43, and takes out the mixed rice through the discharge gutter 41. Mixing 1 The mixing ratio B of the rice is automatically adjusted to be the same as the dehulling ratio A of the hulling section 1.

As described above, the present invention includes the hulling section 1, the six-pot type dissimilar grain selection section 18 provided on the side of the hulling section 1, and the mixed rice hulled by the hulling section 1. A conveying device for supplying to the dissimilar grain sorting section 18 and a mixed rice discharge gutter 41 are provided in the rotary tube 19 of the dissimilar grain sorting section 18. A sensor 12 is provided to detect the rice mixing ratio A, and a sensor 50 is provided in the discharge flow path of the mixed rice discharge gutter 41 to detect the mixing ratio B of the mixed rice taken out to the mixed rice discharge gutter 41. A mixed rice regulating valve 43 is provided on the rotation rising side of the gutter 41 so as to be openable and closable.The sensor 12 and the sensor 50 control the mixed rice regulating valve 43 so that the dehulling rate A and the mixing rate B are approximately equal to 2. The dehulling rate of the mixed rice supplied into the horizontal shaft rotating tube 19 is adjusted by the dropping flow path 9. Since the dehulling rate of the mixed rice that falls remains constant at all times, it has the effect of significantly improving the efficiency of the device.
