Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic hulling roll gap adjustment device of a hulling device.

The sorting action of the pot-hole rotary grain sorting device is to supply mixed rice to a horizontal rotary tube installed in the grain sorting device, and remove the brown rice that has sunk to the lower layer of the mixed rice, which has a higher specific gravity, from the inner surface of the rotary tube. Brown rice is sorted by scooping it up with a hole formed in the pot, but by increasing the rotation speed of the rotating cylinder, the efficiency of sorting mixed rice can be increased.

However, if the rotating speed of the rotary tube is simply increased, the unhulled rice inside the rotary tube will be scooped up together with the brown rice, and the unhulled rice will be mixed into the brown rice.

This defect can be overcome by supplying more brown rice into the rotary cylinder in proportion to the increased rotational speed of the rotary cylinder.

Therefore, in the present invention, when the rotation speed of the rotating tube is increased,
The aim is to automatically increase the dehulling rate of unhulled rice in accordance with the rate of increase in rotation. In the one provided with a hulling section having a movable hulling roll,
The rotation of the horizontal rotating cylinder is adjustable, and the hulling roll has a roll gap that can be adjusted wide and narrow, and when the rotational speed of the horizontal rotating cylinder is adjusted, the gap between the hulling rolls increases.

opens onto the supply gutter 42. Reference numeral 48 denotes a live lower opening of the supply m42 provided on the supply side of the horizontal shaft rotating cylinder 28.

FIG. 4 is a front view of the dissimilar grain sorting section 27, and in the figure, 49
is a variable pulley attached to the rotating shaft 5o of the supply spiral 43, and the rotating shaft 5o is connected to a power source on the hulling section 1 side via a counter (not shown) or the like. Reference numeral 51 denotes a tension pulley, which is pivotally attached to a connecting rod 52 whose base is pivotally attached to the shaft 50, and a wire 53 is locked to the rotating end of the connecting rod 52.

Multiply it.

Therefore, a sensor 64 is provided on the inner surface of the upper side of the dissimilar grain sorting section 27, and a sensor 65 is provided on the portion of the horizontal shaft rotating cylinder 28 corresponding to the sensor 64.
5 detects the rotational speed of the horizontal shaft rotating cylinder 28 and controls the motor 19.

Next, we will discuss the effect.

When unhulled rice is supplied to the stake hopper 2, the hulling roll 3.4
The rice husks are husked and dropped into the wind sorting section 21, the rice husks are sucked by the suction blower 22, the mixed rice falls into the mixed rice receiving trough 25, and the immature rice falls into the immature rice receiving trough 26. The mixed rice that has fallen into the mixed rice receiving trough 25 is transported horizontally by the mixed rice conveyor 23 and placed in the thrower.
46 , rises thereupon, and is supplied to a supply hopper 47 . Since the supply hopper 47 opens into the supply gutter 42, the mixed rice is conveyed by the supply spiral 43 to the drop port 48, and is supplied from the drop port 48 into the horizontally rotating cylinder 28.

Since the horizontal shaft rotating cylinder 28 is rotating counterclockwise in FIG. 3, the mixed rice becomes a descending layer as it rotates, and is biased toward the rotating upward side 38. Since the lower layer of the descending M layer is brown rice, the grain that fits into the pot hole 29 is brown rice, and the Ma axis rotating cylinder 28
As the rice rotates, the mating rises and falls into the finished rice receiving gutter 30, which is transported by the finished rice collection conveyor 31, falls through the take-out port 32, and is transferred from the finished rice take-out gutter 33 to the finished rice take-out conveyor. 34.

Therefore, in order to increase the sorting efficiency, when the rotation speed of the horizontal shaft rotary cylinder 28 is increased by operating the Shihachi-54, the rotation speed of the horizontal shaft rotary cylinder 28 is detected by the sensor 64 and the sensor 65. The motor 19 is controlled through a control circuit to narrow the interval between the fixed hulling roll 3 and the movable hulling roll 4 to increase the dehulling rate of unhulled rice. As a result, the ratio of brown rice supplied to the rotary tube 28 increases, so even if the rotation speed of the rotary tube 28 is increased, only brown rice is selected as finished rice, and unhulled rice is not mixed into the finished rice.

The sorting efficiency of the six-rotary grain sorting device can be increased by increasing the rotation speed of the rotary cylinder, but if the rotation speed is simply increased, the unhulled rice will be scooped up together with the brown rice, and the unhulled rice will be mixed into the brown rice. I end up.

However, the present invention provides a dissimilar grain sorting section 19 having a horizontal shaft rotating cylinder 28 with a large number of pot holes 29 formed on the inner surface, and a hulling section 1 having a fixed hulling roll 3 and a movable hulling roll 4. In this case, the horizontal axis rotating cylinder 28 is formed to be rotatably adjustable, the hulling rolls are formed with a roll gap that can be adjusted wide and narrow, and when the rotational speed of the horizontal axis rotating cylinder 28 is adjusted, the paddy grains are removed. Since the automatic hulling roll gap adjustment device installed on the huller is configured so that the roll gap between the rubbing rolls is automatically adjusted wide and narrow, even if the rotational speed of the rotary cylinder 28 is increased, the rotational speed will not change. In accordance with the rising rate, the de-#ing rate of unhulled rice is automatically increased to increase the ratio of brown rice supplied to the rotary cylinder 28, so unhulled rice is not mixed into the finished rice, and the sorting efficiency can be improved. can.
