Abstract

PURPOSE:To ensure that small grain rice drops and is discharged favarably and thereby sorting the small grain rice is performed efficiently by providing a separation/ transporting device for small grain rice consisting of a lower spiral blade for transporting the unhulled rice grain and a trough for receiving a separation net for small grain rice which is near almost the entire periphery of the spiral blade. CONSTITUTION:This hulling/separating machine is composed of a hulling part A, a fallen rice air-blast separation part B which selects hulled rice at the hulling part A using an air blast, and a mixed rice selection part C which separates the hulled rice from the unhulled rice in the fallen rice after air blasting. Further, the mixed rice which circulates again to the mixed rice separation part C after separation by the mixed rice selection part C is transported to a mixed rice hoisting machine 2 through a separation/transport device 29 for small grain rice which transports the mixed rice with the concurrent removal action of the small size grain. After that, this separation/transport device 29 for small grain rice 29 is equipped with a separation screen receiving trough 33 which comes near to almost the entire periphery of a comparatively low spiral blade 30 for transporting the unhulled rice, excepting the spiral blade 30 and an inflow aperture part through which the unhulled rice runs from above.

2. Description of the Related Art A hulled part for hulling, a downland rice wind selection part for wind-selecting the downland rice in the hulling part, and a mixture for separating and selecting downland rice after hulling wind selection. A hulling and sorting machine equipped with a rice sorting unit and a fried grain transporting unit that transports grain, as a device for selectively removing small rice from brown rice and mixed rice taken out from the rocking sorting device type mixed rice sorting unit. Japanese Patent Publication No. 61-11678.

[0003]

However, in this conventional apparatus, while the brown rice taken out from the rocking sorting apparatus is conveyed by the vibrating conveyor, fine powder such as bran is removed from the small holes and shaken. Remove the small rice and green rice from the mixed rice by introducing the mixed rice taken out from the dynamic sorting device to the launder with the sorting hole and swinging the launder along with the sorting plate to remove the small rice and green rice. The flow trough had a short sorting distance, and the removal of small rice and green rice was insufficient. In view of this, the present invention intends to increase the efficiency of small rice removal by specially configuring the mixed rice taken out from the mixed rice sorting unit such as the swing sorting device with the grain conveying spiral and the small rice sorting net. Is.

Further, the mixed rice distributed unevenly in the mixed rice distribution basin, which is an intermediate portion in the lateral direction of the rocking sorting plates 16, 16, ... Is separated by the brown rice partition plate 19 and the paddy partition plate 20 and taken out, and then the mixed rice. Is a small rice sorting and conveying device 2 through a mixed rice receiving gutter 23 and a mixed rice flow path 24.
9, the small rice sorting and conveying device 29 removes small rice and green rice, and then flows into the lower portion of the mixed rice fried machine 2 to fried the rice.
Furthermore, mixed rice hopper 14, distribution gutter 17, distribution case 18
After that, it is supplied to the swing selection plates 16, 16, ... Further, the ununiformly distributed paddy in the paddy distribution basin on the side of the rocking sorting plates 16, 16, ... Is partitioned by the paddy partition plate 20 and taken out, and the paddy receiving trough 25, the paddy flow path 26, and the paddy paddy. After passing through the fried machine 27, the fried grain is reduced to the hulled portion A, and then hulled again.

Although the rice is sorted in the above-described manner, the mixed rice distributed unevenly in the mixed rice distribution basin of the rocking sorting plates 16, 16, ... Is mixed rice gutter 23, mixed rice flow path 24 and Small rice and green rice are removed by the small rice sorting and conveying device 29 in the process of circulating through the small rice sorting and conveying device 29 to the swing sorting device 15, but the large-diameter spiral shaft 31 has a low height spiral blade 30. Attached, and the grain inlet 34 is arranged above the portion of the spiral wing 30 that rotates from the upper side to the lower side. With this inlet 34 left, the small rice sorting net gutter 3
Since the small rice sorting / conveying device 29 is configured so that 3 covers substantially the entire outer peripheral portion of the spiral blade 30, the mixed rice falling from above is smoothly rotated by the spiral blade 30 rotating from above to below. The mixed rice in a thin layer is received and supplied to the lower part of the small rice screening net gutter 33, and the thin layer mixed rice flows along substantially the entire inner peripheral surface of the small rice screening net gutter 33. When transported to the terminal side, small rice and green rice satisfactorily leak through the small holes of the small rice sorting net receiving gutter 33, and small rice sorting can be efficiently performed.

[0014]

Since the present invention is configured as described above, when the mixed rice sorted by the swing sorting device 15 is supplied to the small rice sorting and conveying device 29 during the circulation, the mixed rice has a relatively high height. The thin layer of mixed rice is conveyed by the low spiral blade 30 while being pressed against the small rice sorting net gutter 33 provided close to the entire circumference of the spiral blade 30 to effectively flow the small rice sorting net gutter 33. Small rice can be satisfactorily discharged through leakage, and small rice can be sorted efficiently.
