  Grains such as brown rice sorted by the swing sorting plate 18b are partitioned by the cocoon partition plate 18c and the brown rice partition plate 18d and discharged from the swing sorting plate 18b. At this time, when the distribution distribution of the grains on the rocking sorting plate 18b is unstable, the switching valve 22 causes the mixed rice flow path 20 and the brown rice flow path 21 to communicate with each other so that the mixed rice and brown rice flows. Is allowed to flow again into the catcher 15, but when the distribution of grain drift on the rocking sorting plate 18b is stabilized, the mixed rice flow path 20 and the brown rice flow path 21 are blocked. Can be switched.

  As a result, the mixed rice falls into the mixed rice flow path 20 and is conveyed again to the sorting unit 18 through the receiving pad 15, and the brown rice is passed from the brown rice flow path 21 through the brown rice cerealing machine 6 to the finished rice outlet 9. Is taken out of the machine. Moreover, the return rice cake which is a return grain is returned to the hopper 2 by the reduction elevator 7a from the return rice cake outlet portion 16b through the return rice cake inlet portion 16a that has flowed in from the rice cake flow path 19, and is crushed again.

  Next, a specific configuration of the dust removal air passage communicating with the compressed air tang, which is a feature of the invention of the present application, is described. FIG. 5 is a perspective view of the bottom of the sorter that schematically shows the finisher, FIG. 6 is a left side view of the finisher, and FIG. 7 is a hull sorter that schematically shows the installation location of the dust removal air passage and the compressed air tang. FIG. 8 is a perspective view of the finisher and the lower part of the sorting board showing the foreign matter removal path around the finisher, and FIG. 9 is a diagram showing the driving force of the hot wind tang. It is a route diagram.

  First, as shown in FIG. 5, on the lower left side (near side) of the swing sorting plate 18b, there is a flow basket 31 and a finish basket 32 such as a screw type diffusion conveyor below the flow basket 31. Further, below this finishing bar 32, a transfer bar 34 such as a screw type transfer conveyor is provided via a finishing wind selector 33, a left side plate 35 shown in FIGS. 1 to 3, and a partition plate shown in FIG. 36 are arranged in parallel with each other.

  Moreover, as shown in FIG. 7, it is above this finishing basket 32, Comprising: It extends over the substantially full length of the finishing basket 32 along the cerealing direction of the body left-right direction in the finishing basket 32 from the left side board 35 to the partition plate 36. Then, a dust removing air passage 37 made of a metal having a rectangular shape with an open bottom is installed. The shape and material of the dust removal air passage 37 are not limited to those described above. Further, in FIG. 7, description of the finishing bar 32 and the transfer bar 34 is omitted.

  Further, between the partition plate 36 and the right side plate 38, in the vicinity of the finish wind selection unit 33, the compressed wind communicated with the finish wind selection unit 33 through an opening provided in the partition plate 36. Kara 39 is installed in the left and right direction of the aircraft.

  Further, the dust removal air passage 37 and the compressed air tang 39 communicate with each other through the connection air passage 40 attached to the left plate 35 side of the partition plate 36 and the opening of the partition plate 36.

  And the terminal part by the side of the partition plate 36 of the transfer rod 34 is connected by the lower part of the cerealing machine 6. FIG.

  As shown in FIG. 9, the drive shaft 39s of the compressed air tang 39 is connected to the drive shaft 11s of the main shaft roll 11a in the removing roll 11c via a belt V1, and the drive shaft of the main shaft roll 11a. 11s is connected to a drive shaft Ms of a motor M installed near the center of the machine body via a belt V2. Therefore, the compressed air tang 39 is used as a power transmission path driven by the motor M through the main shaft roll 11a.

  Here, when the brown rice obtained from the rocking sorting plate 18b by the rocking sorting operation is taken out of the machine as the finished grain, as shown in FIG. It falls to the downfall 31 and falls to the left side plate 35 side of the finishing bowl 32 provided below through the inflow opening opened to the downfall 31 by the standing of the switching valve 22.

  Next, the brown rice is cerealed while being diffused by the conveyor toward the partition plate 36 in the finishing bowl 32. At this time, as shown in FIG. 8, the air around the finishing bowl 32 is sucked from the opening at the bottom of the dust removal air passage 37 through the connection air passage 40 by the compressed air tang 39, so These foreign matters are sucked into the dust removal air passage 37 from the brown rice mixed with foreign matters such as small dust and dust while moving through the air 32 and discharged from the compressed air tang 39 to the outside of the machine through the connection air passage 40. .

  For this reason, there is no need for frequent maintenance of the finisher 32 without causing problems such as foreign matter accumulating in the finisher 32 and clogging of the finisher 32, and brown rice can smoothly pass through the finisher 32. Therefore, working efficiency can be improved.

  Next, the brown rice falls from the gap of the opening valve 41 that can be set to the opening degree, which forms the receiving of the finishing tub 32, and is guided by the guide plate 42 and falls to the lower finishing wind selector 33. At this time, since the air in and around the finishing wind selection unit 33 is sucked by the compressed air tang 39, the brown rice remains in the brown rice in the process of falling from the finishing basket 32 to the finishing wind selection unit 33. Dust and foreign matter such as dust are reliably sucked by the compressed air tang 39 and discharged outside the apparatus.

  For this reason, it is not necessary to suck and remove the foreign matter remaining on the brown rice of the finishing wind selection unit 33 by using the suction fan 13 of the wind selection unit 12 installed at a position separated from the finishing wind selection unit 33 as in the past. Therefore, the suction force (wind selection efficiency) of the wind selection unit 12 is not impaired, and the foreign matter accumulated in the vicinity of the finisher 32 and the finish wind selection unit 33 is increased by the compressed air tang 39 installed in the vicinity of the finish wind selection unit 33. Efficient suction removal is possible.

  The brown rice from which foreign matter has been removed by the finishing wind selection unit flows into the brown rice cerealing machine 6, rises in the brown rice cerealing machine 6, and is taken out from the finishing rice outlet 9.

  As described in detail above, the rice hull sorting apparatus 1 of this example winds the mixed grain obtained by thawing the raw material grain with the deflation roll 11c of the degleaming unit 11 by the wind selection unit 12. The intermediate grain and the selected grain are provided, and the reduction part 7 for reducing the intermediate grain to the depulping part 11 by the reduction elevator 7a (conveyance body) and the swinging selection part 18 for further selecting the selected grain are provided, and the swinging is performed.
