Abstract

PURPOSE:To reduce the circulation speed of a mixed rice containing immatured rice grains discriminated by a rocking selection device 12 with a special contrivance provided and thereby increase the selection efficiency of the immatured rice grains when a rice hulling selection device consisting of a rice hulling part A, a non-hulled rice blast selection part B and a sliding selection device-type mixed rice selection part C is employed. CONSTITUTION:A mixed rice containing immatured rice grains discriminated by a shaking selection device 12 of a mixed rice selection part C is wind-selected at a non-hulled rice wind selection part B and then the wind-selected mixed rice is again supplied to the shaking selection device 12 for re-selection. Subsequently, if the mixed rice containing immatured rice grains which is distributed between the unpolished rice distribution flow area and the mixed rice distribution flow area of the shaking selection plate 12 is again wind-selected by the non-hulled rice wind selection part B, the comparatively light immatured rice grains are discharged to an area outside the unhulled rice selection device through a suction fan 14 and a discharged dust cylinder 15 and removed. On the other hand, the comparatively heavy immatured rice grains are supplied to a shaking selection plate 16 and re-selected. In this process, the comparatively heavy immatured rice grains are likely to be distributed in the unpolished rice distribution flow area. Subsequently, the circulation of the immatured rice grains in the shaking selection device 12 is minimized and thereby the selection efficiency is increased.

After passing through the distribution case 17, the mixed rice that has been wind-sorted again in the sliding rice wind sorting path 9 is supplied to the swinging sorting plates 16, 16, . The rice flows down the paddy rice flow path 25 and flows into the paddy lifting machine 26 of the grain-lifting section D, and is returned to the hulling section A by the hulling machine 26 to be hulled again. In addition, when taking out the brown rice sorted by the oscillating sorting device 12, the brown rice grain lifting machine 22 is replaced with a stone removal sorting device (not shown) after destoning and sorting, and then a vertical grain sorting device is used. (not shown) may be configured to sort the grains by size and then take them out of the machine.

[0010] In supplying the brown rice after sorting in the oscillating sorting device 12 to the lower destoning sorting device 27, the process shown in FIG.
As shown by the solid line or the imaginary line, if the brown rice flow path 30 is positioned between the swinging arms 28, 28, . . . , and the crankshaft 29 located below the swinging sorting plate 16, The entire swing sorting device 12 can be downsized. In addition, in supplying the brown rice after sorting from the oscillating sorting device 12 to the de-stoning sorting device 27, as shown in FIG. By setting it as , the brown rice flow position can be optimized and the accuracy of stone removal and sorting can be improved.

[0011] The hulling and sorting machine includes a hulling section A for removing the hulls, a rice sorting section B, a mixed rice sorting section C of a swing sorting device type, and a fried grain conveying section D for frying the grains. As shown in FIGS. 7 and 8, the hulling section A is placed at the lower front,

(not shown) may be arranged. With this configuration, the swinging sorting device 12 of the mixed rice sorting section C is located above the hulling section A, and the swinging sorting plate 16 and the swinging sorting device 12 return the unhulled rice to the hulling section A after sorting. The conveyance and reduction can be carried out by the vibration conveyor 31 that swings integrally, and the reduction device can be simplified.

Next, the operation of the embodiment will be explained. When carrying out hulling sorting work with a hulling sorter, each rotating part of the machine is driven to supply paddy to the paddy hopper 1, and when the paddy is supplied to the hulling rolls 2, 2, they move in opposite directions. The crushed rice that has been hulled by the rotating hulling rolls 2, 2 and spread by the diffusion plate 3 flows down on the crushed rice flow lower plate 4, and the crushed rice is a mixture of paddy, brown rice, and rice husks. The grains flow into the lower part of the mixed rice lifting machine 5 of the grain conveying section D, are fried, and are supplied to the mixed rice hopper 8 of the scraped rice sorting section B.

[0013] Next, when the rice drops from the wide outlet of the mixed rice hopper 8 to the entire width of the rice selection path 9 below, it is sorted by the sorting wind flowing through the rice selection path 9. is,
Light rice husks flow to the terminal side of the sliding rice flow path 9 and are discharged outside the machine via the suction fan 14 and the dust exhaust tube 15, and relatively light rice husks flow to the terminal side of the sliding rice flow path 9, and are discharged outside the machine through the suction fan 14 and the dust exhaust tube 15. The rice is sorted into a receiving gutter (not shown), and heavy paddy and brown rice are flowed down almost the entire width of the fallen rice receiving gutter 11 and supplied to the distribution case 17.
Via the distribution case 17, each swinging sorting plate 16, 16,
...supplied to...

In this way, the swinging sorting plates 16, 16,
The mixed rice supplied to the supply side 16a and the shaking side 16b of... is caused by the horizontal and diagonal up and down reciprocating movement of a swinging arm (not shown), which causes differences in grain size, specific gravity, or frictional resistance. The brown rice that has been sorted and distributed unevenly in the brown rice distribution basin on the horizontal shaking side is separated by a brown rice partition plate 19 and taken out, fried by a brown rice grain lifting machine 22, and taken out of the machine. In addition, the mixed rice unevenly distributed in the mixed rice distribution area, which is the lateral middle part of the oscillating sorting plate 16, is
9 and paddy partition plate 20 and taken out, the mixed rice passes through the mixed rice channel 23 and is fried in a thrower-type mixed rice frying machine 24, and is sent to the sub hopper 8b of the mixed rice hopper 8, After passing through the rice wind selection route 9, the suriro rice receiving trough 11, and the distribution case 17, the rice is sorted again at the suriro rice wind selection route 9, and then the oscillating sorting plates 16, 16
, ... and re-sorted, and distributed unevenly in the unhulled rice distribution area on the lateral shaking side 16b of the oscillating sorting plate 16, is separated by the unhulled partition plate 20 and taken out. 2
At step 6, the grain is returned to the hulling section A, where it is hulled again.

In the process of hulling and sorting in this way, when the mixed rice containing green rice is sorted by the swinging sorting plate 16, as shown in FIG.
As shown in the figure, the green rice is distributed between the brown rice distribution area and the mixed rice distribution area, and the relatively light green rice is removed together with the mixed rice from the sub-hopper section 8b of the mixed rice hopper 8 in the mixed rice lifting machine 24. It is supplied to the terminal side of the Rakumae wind selection route 9 and is re-sorted. When the green rice is wind-sorted again in this way, it is supplied to the sorting end side compared to the fallen rice supply position of the fallen rice wind selection path 9.
The well-sorted and relatively light green rice is discharged and removed outside the machine via the suction fan 14 and the dust exhaust pipe 15, and the comparatively heavy green rice is supplied to the swinging sorting plate 16 and sorted. Since there is a relatively high probability that green rice with a heavy target will be distributed in the brown rice distribution area, it is possible to increase the sorting efficiency by reducing the circulation amount of green rice in the shaking sorter 12.

[0016]

Effects of the Invention As described above, the mixed rice containing green rice sorted by the oscillating sorting plate 16 of the mixed rice sorting section C is divided into mixed rice after being wind sorted by the fallen rice sorting section B. Since the rice is supplied to the oscillating sorting device 12 of the sorting section C and is sorted again, relatively light green rice is discharged and removed outside the machine during the wind sorting process in the fallen rice wind sorting section B, and comparatively heavy green rice is removed from the machine. In the process of being supplied to the oscillating sorting plate 16 and being re-sorted, the green rice is relatively likely to be distributed in the brown rice distribution area, so it is taken out of the machine along with the brown rice.
By reducing the circulation amount of green rice in the oscillating sorting device 12, sorting efficiency can be improved.
