Abstract

PURPOSE:To simplify a transmission mechanism by allowing the shaft of a supply conveyor, the shaft of a finish rice conveyor and the shaft of a rotary roll to protrude into the interval between a rice hulling part and a mixed rice sorter. CONSTITUTION:The rotary power of a rotary cylinder 23 inclined toward a rice hulling part 1 by an inclination control apparatus and the rotary powers of the screws 26, 34, 36 in the rotary cylinder 23 are transmitted to the rotary shaft 37 of a supply conveyor 36 from a counter provided on the side of the rice hulling part 1 through an output shaft 41 and further transmitted to pulleys 38, 47-50 through a belt 53. The output shaft 42 and the rotary shaft 37 are connected through a coil spring 42 and can transmit power freely. A disc 45 is always pushed out by an energizing spring 46 to prevent the detachment of the coil spring.

(effect) (Overall action) 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 husked and dropped into the wind sorting section 4, the rice husks are wind sorted, the mixed rice falls into the mixed rice receiving trough 8, and the immature rice falls into the immature rice receiving trough 9.

The mixed rice that has fallen into the mixed rice receiving trough 8 is transported horizontally by the mixed rice conveyor 6 and flows into the thrower 58, which is then raised and supplied to the hopper 59.

Since the hopper 59 opens into the supply gutter 35, it is conveyed by the supply conveyor 36 to the drop tube 60 at the end and is supplied into the horizontally rotating tube 23.

Since the horizontal shaft rotating cylinder 23 is rotating, the mixed rice becomes a layered layer as it rotates, and the yr
Stop by. Since the lower layer of the falling layer is brown rice, the grain that fits into the pot hole 24 is brown rice, which rises as the horizontal shaft rotating cylinder 23 rotates and is taken out to the finished rice receiving trough 25, and is taken out by the finished rice conveyor 26. The rice is transported horizontally to the take-out port 27 side, falls through the take-out port 27, and is transferred to the finished rice take-out conveyor 29 from the finished rice take-out gutter 28.
is retrieved via.

When the amount of grain fed into the horizontal shaft rotary cylinder 23 decreases, when the sorting efficiency on the falling cylinder 60 side of the rotary cylinder 23 is high, or in order to dispose of residual rice etc. in the rotary cylinder 23, the rotation By operating the movable lever 17, the inclination adjustment device 13 moves the rotary cylinder 23.
When the falling barrel 60 side is moved upward, this upward movement causes the grains supplied into the horizontal rotating barrel 23 to move to the takeout port 27 side, increasing the thickness of the falling layer and mixing well. Sorting the rice,
Alternatively, the remaining rice in the rotary cylinder 23 is discharged.

Therefore, the rotational power of the rotary cylinder 23 tilted with respect to the hulling part l side by the inclination adjustment device 13 and the rotational power of each spiral 26, 34, 36 in the rotating cylinder 23 are provided on the hulling part l side.
