Description

  The present invention relates to a grain sorter that sorts grain and debris.

  As a grain sorter, grain mixed with debris is supplied on a perforated plate, so that grains and debris are sorted and discharged from the grain outlet, and debris is discharged from the stone outlet. (For example, refer to Patent Document 1).

  In this grain sorter, the perforated plate is oscillated and air is blown from the lower side onto the perforated plate. When grain containing mixed stone dust is supplied onto the perforated plate, the lower layer is formed on the perforated plate. A relatively heavy stone is placed on the upper layer and a relatively light grain is placed on the upper layer, and the grain and the stone are moved to the opposite side, so that the grain and the stone are sorted out.

However, if there is less grain and stones present on the perforated plate, even if air is blown from the lower side on the perforated plate, it is difficult for the grain to be placed on the upper layer of the stone, making it difficult to move the grain. There is sex. As a result, it is difficult to completely discharge the grain remaining on the perforated plate from the grain outlet even if the grain sorter is continuously operated after the amount of grain and debris existing on the perforated plate is reduced. there is a possibility.

  In the grain suction pipe 70 and the stone dust suction pipe 72, a substantially T-shaped tubular suction device 76 (air gun) constituting the discharging means shown in detail in FIG. 9 is interposed. The grain suction pipe 70 or the stone dust suction pipe 72 is communicated. An end portion of the suction device 76 that is not communicated with the grain suction pipe 70 or the stone dust suction pipe 72 is a compressor (not shown) as a power section of the discharge means via a supply pipe (not shown) as a communication section of the discharge means. It is communicated to. The supply pipe is provided with an electromagnetic valve 78 as an operating part of the discharge means. When the electromagnetic valve 78 is closed, communication between the suction device 76 and the compressor through the supply pipe is interrupted.

   Next, the operation of the present embodiment will be described.

  In the grain sorter 10 having the above configuration, when the drive motor 62 is driven and actuated to start the sorting operation, the main blower case 20 and the sub blower case 44 swing together. Further, the main blower 28 rotates to blow air from the lower side through the numerous through holes 24 onto the primary sorting porous plate 22, the transverse feed porous plate 36 and the return porous plate 40, and the sub blower 54 It rotates and air is blown onto the secondary sorting perforated plate 46 from below through a large number of through holes 24. Next, when the grain K in which the stone waste Z is mixed is supplied from the supply hopper 18 onto the primary sorting porous plate 22, the grain K in which the stone waste Z is mixed into the grain K and the stone waste Z on the primary sorting porous plate 22. Primary selection.

  That is, as shown in FIG. 5, on the primary sorting perforated plate 22, the grain K is light so that it floats as a whole, the stone dust Z is heavy and does not float, and the grain K that floats fluctuates under it. Since it does not come into contact with the inclined projections 26 of the porous plate 22, it floats and is distributed neither forward nor backward, and the stone chips Z are moved forward by the inclined projections 26 of the primary sorting porous plate 22.

  Furthermore, when a new grain K is supplied from above, the grain K is moved metabolically by the supplied amount, and the new grain K slides backward on the grain K that has already surfaced. In this form, the grain discharge rod 66 is discharged out of the machine body 16, and the grain K containing the stone debris Z reaches the transverse feed perforated plate 36.

  On the laterally perforated plate 36, the grain K containing the stone debris Z is sequentially conveyed rightward and reaches the return porous plate 40. Further, on the return perforated plate 40, the grain K containing the stone debris Z sequentially moves backward. To the secondary sorting perforated plate 46.

  The grain K containing the stone waste Z supplied onto the secondary sorting porous plate 46 is further sorted into the grain K and the stone waste Z by the same action as the primary sorting porous plate 22, and the grain K moves backward. Then, it is discharged from the grain discharge basket 66 to the outside of the machine body 16, and the stone chips Z are moved forward and discharged from the stone chip discharge basket 68 to the outside of the machine body 16.

  By the way, when the supply of the grain K mixed with the stone waste Z to the supply hopper 18 is finished and the amount of the grain K mixed with the stone waste Z on the primary sorting porous plate 22 is reduced, the grain sorting on the primary sorting porous plate 22. Even if air is blown from the lower side, the grain K is difficult to be arranged on the upper layer of the stone chips Z. For this reason, the grain K is moved forward by the inclined protrusion 26 of the swinging primary sorting porous plate 22 and remains (residence) mainly on the front end portion of the primary sorting porous plate 22, and the stone dust Z is primary sorting porous. It is moved forward by the inclined projection 26 of the plate 22 and mainly remains (stays) on the transverse feed porous plate 36.

  Here, immediately before the drive of the drive motor 62 is stopped and the operation of the grain sorter 10 is stopped thereafter (particularly, when a different kind of grain K is subjected to a sorting process when the grain sorter 10 is operated next time). The electromagnetic valve 78 corresponding to the grain suction pipe 70 and the electromagnetic valve 78 corresponding to the stone suction pipe 72 are opened separately or simultaneously at different times, so that the suction device 76 and the compressor can supply the supply pipe. The air compressed and compressed by the compressor is supplied to the suction device 76 via the supply pipe. Accordingly, the suction device 76 sucks air from one end side (primary sorting perforated plate 22 side) of the grain suction pipe 70 to the other end side (cereal discharge rod 66 side), so that the front end portion of the primary sorting perforated plate 22 is sucked. Grain K remaining on the top is sucked into the grain suction pipe 70, transported into the grain discharge basket 66, and discharged out of the machine body 16 from the grain discharge basket 66. Further, the suction device 76 sucks air from one end side (the lateral feed porous plate 36 side) of the stone dust suction pipe 72 to the other end side (the stone waste discharge rod 68 side), so that the top of the lateral feed porous plate 36 is obtained. The remaining stone waste Z is sucked into the stone waste suction pipe 72 and conveyed into the stone waste discharge rod 68 and discharged from the stone waste discharge rod 68 to the outside of the machine body 16. Further, the separation device 74 between the stone dust suction tube 72 and the stone dust discharge rod 68 separates the air (wind) sucked into the stone dust suction tube 72 and the stone dust Z, thereby discharging the stone dust. It is suppressed that only the stone debris Z is conveyed into the coffin 68 and the air sucked into the stone debris suction pipe 72 is supplied to the stone debris discharge rod 68 and discharged from the stone debris discharge rod 68 to the outside of the machine body 16. Is done.

  As described above, even if the grain K remains on the front end portion of the primary sorting porous plate 22 and the stone chips Z remain on the transverse feed porous plate 36, the grains 16 and the stone chips Z can be easily removed in a short time. It can be discharged outside.

  Further, as described above, the grain K remaining on the front end portion of the primary sorting perforated plate 22 is discharged out of the machine body 16 from the grain discharge rod 66, and the debris Z remaining on the transverse feed perforated plate 36 is It is discharged out of the machine body 16 from the stone waste discharge rod 68. For this reason, the grain K and the stone waste Z remaining in the machine body 16 can be sorted and discharged out of the machine body 16.

  The dust in the machine body 16 can also be sucked into the grain suction pipe 70 and the stone dust suction pipe 72 by the suction device 76 and can be discharged out of the machine body 16 from the grain discharge basket 66 and the stone dust discharge basket 68. For this reason, the dust collection operation | work in the body 16 can also be performed.

  Further, the grain sorter 10 can be easily attached with a grain suction pipe 70, a stone dust suction pipe 72, and a suction device 76 (including a supply pipe, a solenoid valve 78, and a compressor). For this reason, the grain suction pipe 70, the stone dust suction pipe 72, and the suction device 76 (including the supply pipe, the electromagnetic valve 78, and the compressor) can be easily attached to the ready-made grain sorter 10 as well.

  In the present embodiment, the separation device 74 is provided between the stone dust suction pipe 72 and the stone waste discharge rod 68. However, in addition to or instead of this, the grain suction pipe 70 is used to remove the grain. It is good also as a structure which provided the separation apparatus 74 between the discharge tanks 66. FIG.
