Based on FIG. 1, the whole structure of the hull sorter equipped with this invention is demonstrated.
The rice hull sorter is an impeller blade type hulling portion 1 capable of hulling at a high removal rate, and a hulled rice that wind-pastes the rice crushed from the hulling portion 1 into brown rice, mixed rice, and rice bran. It is comprised by the wind selection part 2 and the mixed rice selection part 3 which isolate | separates and sorts the mixed rice wind-selected by the sliding rice style selection part 2 into rice bran and brown rice.

  The hulling portion 1 is composed of a hull hopper 6 and an impeller blade type hulling device 7 capable of hulling at a high removal rate of 99.5%, for example. The impeller blade-type hulling device 7 is provided rotatably on the hulling case 7a and the hulling case 7a disposed on one side of the front portion of the hulled rice wind selecting box 9 of the hulled rice wind selecting unit 2. , The impeller blades 7b,..., The cocoon supply cylinder 7c for supplying the cocoon of the cocoon hopper 6 to the center portion of the cocoon case 7a, It is comprised by the cylinder 7d.

  Thus, the kite supplied to the kite hopper 6 is fed to the hulling case 7a through the kite supply cylinder 7c, repelled on the impeller blades 7b,... To the outer peripheral side, and suddenly changed in direction at the outer peripheral bent portion. Most of the crushed rice collides with the outer lining of the rice hull case 7a, and most of it is hulled. Supplied.

Next, the sliding rice style selection unit 2 will be described.
In the brewed rice style selection box 9 of the brewed rice style selection unit 2, a brewed rice selection wind path 10 through which the selection wind flows from the front side to the rear side is obliquely installed in a rear-up manner. A brown rice tray 11 is provided below the start end portion 10a of the brewed rice sorting air passage 10, a mixed rice tray 12 is provided below the middle portion, and a rod tray 13 is provided below the terminal side 10b. ing. A suction fan 14 is provided above the terminal portion 10 b of the brewed rice sorting air passage 10, and a dust exhaust cylinder 15 is connected upward to an exhaust portion of the suction fan 14. In addition, the soot that has been fallen and sorted by the soot receiving bowl 13 flows down to the soot reducing passage 21, and the end portion of the soot reducing passage 21 is connected to the soot casing 7a, and soot is sucked by the suction air of the soot casing 7a. It is configured as follows.

  The unpolished rice selected by the unpolished rice paddle 11 is transported to one side of the machine body by the unpolished rice helix 11a, and is supplied to the lower part of the thrower-type brown rice milling machine 16, for example, and taken out of the machine.

In this configuration, the plate 19 is opened and returned to the starting end portion 10a of the sliding rice sorting air passage 10 to be subjected to wind selection processing. That is, since the dust-absorbing wind acts in a folded manner from the dust-absorbing passage 17 c toward the suction fan 14, heavy grains are blocked by the opening / closing plate 19 in the grain-holding chamber 18.

  Thus, the brewed rice that has been crushed by the rice husk case 7a is supplied to the brewed rice supply box 5 through the brewed rice transfer cylinder 7d, and is diffused by a diffusion device (not shown) of the brewed rice supply box 5. On the other hand, it is supplied to the start end side of the sliding rice sorting air passage 10 and is wind-selected. A large amount of brown rice in the sorting object is fall-sorted to the brown rice tray 11, transported to one side of the machine body by the brown rice helix 11 a, and taken out directly from the machine by the brown rice cerealing machine 16.

  Further, the wind force of the suction fan 14 is set to be relatively strong so that all of the soot mixed in a small amount can be transferred from the intermediate portion of the sorting air passage 10 to the end side, and the brown rice is also partially transferred. Therefore, the mixed rice of rice bran and brown rice is fall-sorted to the mixed rice receiver 12 and sent to the mixed rice sorting unit 3 by the mixed rice cerealing machine 20. Further, the light soot is sorted into the soot receiving basket 13 and flows down to the soot reduction passage 21, flows to the terminal side of the soot reduction passage 21 by the suction force of the hulling case 7 a, is sucked and reduced into the hulling case 7 a, and then refilled again. It is slid. In addition, rice husks and dusts are discharged from the terminal side 10b of the brewed rice sorting air passage 10 through the suction fan 14 and the dust discharge cylinder 15 to the outside of the machine.

  The brown rice selected by the brown rice receiving pad 11 is transported to one side of the machine body by the brown rice helix 11a, pulverized by the brown rice cerealing machine 16, and supplied to the brown rice dust suction device 17. Then, brown rice diffuses in the flow down passage 17b in a zigzag manner to disperse the brown rice and dust, and the brown rice is taken out of the machine from the flow down passage 17b. Dust is sucked and removed from the lower part of the flow-down passage 17b to the dust-collection passage 17c by the suction force of the suction fan 14, and flows to the end side. Heavy grains in the dust flow down from the end side of the dust suction passage 17c to the grain storage chamber 18, and when a predetermined amount of grains accumulates, the opening and closing plate 19 is automatically opened to start the sliding rice sorting air passage 10. It is reduced to the part and sorted again. Light dust flows from the end portion of the dust suction passage 17c to the suction fan 14 and is discharged out of the machine through the dust exhaust cylinder 15.

  In the above embodiment, the brown rice to the brown rice receiver 11 is wind-selected by the brewed rice sorting air passage 10, and a large amount of brown rice in the sorting object is received by the brown rice receiver 11, It is configured to be directly taken out of the machine, and the brown rice dusting device 17 is laid on the brown rice cerealing machine 16, and the brown rice cerealing machine 16 cereals the brown rice recovered through the mixed rice sorting unit.
