A lower sorting plate 6 having a foreign matter sorting hole 4 for allowing small foreign matter to leak and a brown rice port 5 is provided, and the upper and lower sorting plates 3 and 6 are integrally swung to be supplied to the fed brown rice. In this configuration, the coarse and fine foreign substances are sequentially sorted and removed from the rice.

  When a predetermined amount of brown rice for milling is supplied to the brown rice input hopper, it is carried into the stone removing device 13 and sorted by the specific gravity sorting action by swinging of the swing sorting plate 12, so that the heavy stone gravel, etc. Is removed, and brown rice, straw scraps and the like are discharged from the brown rice outlet 14 and the like.

  In the form in which the foreign matter sorting device 11 is looked into the brown rice outlet 14 of the stone removing device 13 as described above, the brown rice subjected to the above-mentioned stone removing or rough sorting action is supplied to the upper surface of the upper sorting plate 3. Thus, the swing selection action is performed by the swing action caused by the rotation of the swing shaft 8. The brown rice leaking from the brown rice sorting hole 1 of the upper sorting plate 3 is received by the upper surface of the lower sorting plate 6 and is subjected to the sorting action while the upper surface of the lower sorting plate 6 is swung. Then, coarse foreign matters such as relatively large straw scraps remaining on the upper sorting plate 3 are discharged from the foreign matter opening 2.

The brown rice that has leaked to the upper surface of the lower sorting plate 6 is taken out from the brown rice port 5 at the terminal end of the lower sorting plate 6 in the state where the large stone gravel and foreign matter are removed as described above, and conveyed to the rice milling apparatus side. Supplied.
Further, while the upper surface of the lower sorting plate 6 is swung, a fine foreign matter having a specific gravity larger than that of the brown rice (this specific gravity is larger than the specific gravity of the coarse gravel removed at the stone extraction port 31 of the stone extraction device 13). A large amount of light, fine sand, etc. is subsidized, and it is difficult to be subjected to the oscillating transfer action even by the oscillation of the lower sorting slope 6, but it is formed on the upper surface of the lower sorting plate 6. The foreign material sorting hole 4 is allowed to sink and directly leak onto the lower base plate 10 surface. Fine foreign matters, gravel and the like are subjected to leakage selection from the foreign matter selection hole 4 of the lower sorting plate 6 and can be supplied to the rice milling apparatus as brown rice with little large and small foreign matter mixed therein.

The fine foreign matter leaked and sorted from the foreign matter sorting hole 4 on the upper surface of the lower sorting plate 6 in this way is discharged out of the apparatus from the lower base plate 10 or the like.
A base plate for supporting a swing arm 9 is mounted on the lower side of the lower sorting plate 6 with a swing shaft 8 that is rotated by a motor 7 and swings the upper and lower sorting slopes 3 and 6. The base plate 10 receives and treats foreign matter leaking from the foreign matter sorting hole 4 of the lower sorting plate 6.

  The upper sorting plate 3 and the lower sorting plate 6 are rotated and oscillated through an oscillating shaft 8 by driving a motor 7 disposed below the base plate 10 at the bottom. The base plate 10 is configured to cover the upper surface of the motor 7 and has the function of a motor cover. The brown rice flowing down the upper surface of the base plate 10 flows down from the brown rice port 5 to the outside, and the base plate 10 The fine foreign matter remaining on the upper surface can be taken out from the foreign matter sorting hole 4 or out of the discharge port and taken out to a predetermined container or outside the apparatus.

  Further, a scouring device 13 which sorts the gravel with specific gravity while swinging the foreign sorting device 11 comprising the upper sorting plate 3 and the lower sorting plate 6 upon receiving the supply of brown rice on the upper surface of the swing sorting plate 12. It is provided so as to pass through 14 parts of the brown rice outlet, and receives the brown rice supplied through the stone removing device 13 to remove fine foreign matters.

  Although there is a form that attaches a conventional stone removing device or a coarse sorting device to sort and remove coarse foreign matters, even in such a form, if it is difficult to sort and remove fine foreign matters in brown rice, By installing the foreign matter sorting device 11 like this in the stone removing device 13 or the rough rice exit 14 of the coarse sorting device or the like, the brown rice mixed with the fine foreign matter taken out from the brown rice exit 14 is removed. While supplying to the upper surface of the upper sorting plate 3 of the sorting device 11 and leaking from the brown rice sorting hole 1 to the upper surface of the lower sorting plate 6, the brown rice flows out from the brown rice port 5 of the lower sorting plate 6 and fine foreign matters are It is configured not to be discharged from the foreign matter sorting hole 4 and discharged to the brown rice entrance 5 side. In this way, the brown rice that is swung on the upper surface of the lower sorting plate 6 has a sorting process delayed from the time of the upper sorting plate 3, so that foreign matter such as straw scraps is less mixed and the outflow to the brown rice entrance 5 side is promptly and smoothly. In this case, fine stones and foreign substances sink and easily fall into the different sorting holes 4 so that the separation of the brown rice from the fine foreign substances is facilitated. Make spills difficult to do.

  In FIG. 7, the width of the lower sorting plate 6 is widened, a side wall 38 is formed outside the side wall 36 of the upper sorting plate 3, and brown rice or straw that overflows from the side wall 36 of the upper sorting plate 3 to the side. The dust is guided to the outer edge portion 49 of the lower sorting plate 6 and is swung so that the fine foreign matters are leaked from the sorting hole 4. Reference numeral 50 denotes a guide plate that protrudes from the upper surface of the lower sorting plate 6 and guides and holds the upper sorting plate 3 in the center.

  Next, in FIG. 8, coarse foreign matter (such as straw scraps) discharged from the foreign material port 2 of the upper sorting plate 3 is received by the foreign material chute 51 and accommodated in the container 52, and the sized grain brown rice discharged from the brown rice port 5. Is received by the brown rice chute 53 and guided to the entrance 54 of the rice mill elevator 34. Further, the fine foreign matter received on the upper surface of the base plate 10 can be accommodated in the container 52 from the elongated holes 44 and 45 through the lower foreign matter chute 55. In FIG. 9, fine foreign matter discharged from the long holes 44 and 45 of the base plate 10 can be stored by directly flowing into the container 56 installed below the base plate 10.
