The shell 3 erected on the base 2 is provided with a storage tank 4 at the top and a hopper 5 at the lower side. As shown clearly in FIG. A cylindrical supply cylinder 16 having an open upper surface is fixed on the top plate 2 a of the table 2, and a chute 5 a of the hopper 5 is communicated with a portion above the side wall of the supply cylinder 16. A guide cylinder 17 arranged concentrically in the supply cylinder 16 has a guide blade 17a for guiding the cereal introduced from the hopper 5 downward on its outer peripheral surface, and a flange provided on the periphery of the upper opening. The part 18 is provided with a scrape scraping blade 18a projecting upward, and a low-speed rotating shaft 11a of the two-output gear motor 11 is fixed to the bottom plate 17b.
[0019]
The sorting net body 12 rotates integrally with the guide tube 17 by engaging a slit (not shown) formed in the lower edge portion thereof with a scrape scraping blade 18 a protruding from the flange portion 18 of the guide tube 17. In this manner, the outer peripheral surface in the vicinity of the upper end is supported on the upper partition plate 3c of the shell 3 through the support shaft 21a so as to be freely rotatable so as not to swing.

Is configured to be sucked from the louver 15 into the dust exhaust duct 14 and sucked into the exhaust chamber 7 in the base 2 by the operation of the exhaust fan 8.
[0022]
With the configuration as described above, when the sorting net body 12 and the crushed helix 13 are relatively rotated by the activation of the two-output gear motor 11, the cereal introduced into the guide tube 17 interacts with the sorting net body 12 and the cereal helix 13. While the cereal is being cerealed, waste particles and foreign matters having a particle size smaller than the mesh size of the sorting net body 12 are released into the gap between the sorting net body 12 and the shell body 3. Then, the waste particles fall onto the lower partition plate 3b and are discharged out of the machine through the waste particle discharge port 23 (see FIG. 5) in which the lower partition plate 3b is formed. Thus, the air is sucked into the hollow portion S of the base 2 from the louver 15 through the dust discharge duct 14, and is discharged from the discharge portion 6c to the outside through the exhaust duct 6 through the exhaust chamber 7. On the other hand, good grains and foreign matters having a large particle diameter that do not pass through the mesh of the sorting net body 12 are discharged onto the upper partition plate 3c and are blown off into the storage tank 4 by the good grain scraping blades 19 to be stored in the storage tank 4. It is stored in.
[0023]
As shown clearly in FIGS. 3 and 4, the storage tank 4 for storing good grains is provided with a discharge port 4 a for discharging good grains in the lower part, and the upper wall part is mixed in the good grains. A suction port 4b is provided for sucking and removing foreign matters such as spikelets, straw scraps and bran. And in the lower part of the suction port 4b, a plurality of dispersion plates 4c for dispersing and dropping the good grains that are blown off into the storage tank 4 by the good grain raking blades 19 of the cereal helix 13; 4c... Are attached to the side wall of the storage tank 4, and air inflow windows 4d, 4d through which air flows are formed in the lower part of the side wall of the storage tank 4. A suction duct 4e is connected to the suction port 4b so as to communicate with an upper portion of the upright portion 6a of the exhaust duct 6, and a wind direction adjusting plate 4f is connected to a connecting portion between the suction duct 4e and the exhaust duct 6. 6 projects inwardly (see FIG. 3).
[0024]
By connecting the inside of the storage tank 4 to the exhaust duct 6 through the suction duct 4e in this way, the air flow flowing upward in the exhaust duct 6 by the operation of the exhaust fan 8 in the exhaust chamber 7 is changed to the suction duct 4e. When passing through the wind direction adjusting plate 4f provided at the connecting portion, the air in the storage tank 4 is sucked through the suction duct 4e. As described above, the air in the storage tank 4 is sucked from the suction port 4b, and at the same time, new air flows into the storage tank 4 from the air inlet windows 4d and 4d provided below. An air flow from the lower side toward the upper suction port 4b is generated. Therefore, when the good grains that are repelled into the storage tank 4 collide with the plurality of dispersion plates 4c, 4c... In the storage tank 4 and are dispersed and fall downward, the air flows upward in the storage tank 4. The flow becomes a separation air stream separating foreign matter such as spikelets, straw scraps, bran, etc. mixed in good grains, and the foreign matter is separated from the suction port 4b through the suction duct 4e together with air. The air is sucked into the exhaust duct 6 and discharged from the discharge portion 6 c together with the air flowing through the exhaust duct 6. The flow rate of air sucked from the storage tank 4 through the suction duct 4e can be adjusted by adjusting the angle of the wind direction adjusting plate 4f provided at the communicating portion between the suction duct 4e and the exhaust duct 6.
[0025]
By adopting the above configuration, a dust exhaust duct for removing foreign matter in the storage tank 4 is not disposed in the shell 3, and a special dust exhaust device is not separately provided in the storage tank 4. The foreign matters mixed in the good grains stored in the storage tank 4 can be efficiently removed, and the quality of the good grains stored in the storage tank 4 can be improved.
