The waste is discharged to the outside of the apparatus together with the waste, and the waste after sorting is discharged together with the suction fan 30.
[0012]
Therefore, cereals are transported in large quantities to the threshing device 9 at a time, threshed with the handling cylinder 20 or the like and subjected to leakage treatment, and untreated matter left on the handling cylinder 20 side (included in sawdust and sawdust) Even if a large amount of soot or the like) is generated, soot in the soot is leaked by the dust feeding port processing cylinder 21, and the soot and soot are leaked from the cone cave 37.
And even if soot left and leaked at the end position of the cone cave 37 is generated, the soot is guided into the soot discharge mechanism 90 and jumps off by the rotation of the blades 91, 91. Then, it is discharged out of the machine through the soot discharge port 93.
Therefore, since it does not fall from the terminal part of the dust feed port processing cylinder 21, soot does not accumulate on the casings 81, 82 and the like above the suction fan 30, and the rear part of the dust feed process cylinder 21 The corn cave 37 is not clogged, and the processing capability of the dust-feed port processing cylinder 21 can be maintained high. Since part of the sawdust generated at the time of threshing is discharged by this sawdust discharging mechanism 90, the amount of sorting on the swinging main body 51 side can be reduced correspondingly, and the sorting ability can be improved. In combination with the suction fan 30, the waste discharging ability is improved.
[0013]
Further, in this embodiment, in FIG. 3, the dust is sent to the right side (traveling direction) below the handling cylinder 20 below the straight line connecting the rotation center of the handling cylinder 20 and the rotation center of the dust feeding port processing cylinder 21. A second processing cylinder 40 is arranged on the left side of the mouth processing cylinder 21 and is arranged so as to wrap in a side view as shown in FIG.

[0015]
As shown in FIGS. 3 and 4, the crimp net as a leaking body covering the lower surface of the treatment cylinder 20 is below the right side of the treatment cylinder 20 from the left end of the support frame 35 (on the left side of the second treatment cylinder 40). The crimp net 31 is laid in the range up to. On the support frame 35 on the right side from the right end portion of the crimp net 31, a coarse net 43 having a mesh interval wider than that of the crimp net 31 is laid to form a coarse leak body having a high leak rate. The upper part of the left side of the second processing cylinder 40 is covered with the coarse net 43, and soot and the like are leaked from the coarse net 43 to the second processing cylinder 40.
Instead of the coarse net 43, a cone cave 44 shown in FIG. 5 can be laid to further promote leakage.
[0016]
As shown in FIGS. 3 and 6, a leakage net 42 is laid on the lower semicircular arc portion of the second processing cylinder 40 along the rotation trajectory of the blade-like teeth 41. The left end portion of the leakage net 42 is extended to a position where it abuts on the right end portion of the crimp net 31 at the bottom of the handling cylinder 20. The tangential direction of the right end portion of the crimp net 31 (the left end portion of the coarse net 43) coincides with the tangential line of the outer periphery of the second treatment cylinder 40, and the wrinkles guided by the tooth handling 27 of the treatment cylinder 20 It is configured to easily pass through and leak into the second processing cylinder 40, and the amount of soot and the like to be processed on the handling cylinder 20 side is reduced to prevent generation of sag particles.

The reed or the like swung along with the rotation of the second processing cylinder 40 leaked from the coarse net 43 passes through the coarse net 43 and does not return to the handling cylinder 20 side. Guide to 40 side.
Further, since the direction of rotation of the dust feeding port processing cylinder 21 is also the reverse direction, the leakage from the leakage net 42 of the second processing cylinder 40 mainly from the right side (Glen tank 12 side), In the dust-feed port processing cylinder 21, leakage mainly occurs from the left side, and the position of falling on the swinging main body 51 is shifted to the left and right to improve the distribution and enhance the sorting performance.
[0018]
A cutting blade 45 is fixed to the left end portion of the leakage net 42 here. The blade surface of the cutting blade 45 is arranged in a direction opposite to the rotation direction of the second processing cylinder 40 so as to cut the rotating scraps along with the rotation of the second processing cylinder 40 so as to increase the processing capacity. I have to.
In addition, since the cutting blade 45 is disposed along the tangential direction of the right end portion of the crimp net 31, the flow of scissors or the like thrown into the second processing cylinder 40 side is not deteriorated. ing.
[0019]
Further, an end portion of the reduction conveyor 14 is arranged on the right side of the middle part of the front and rear of the second processing cylinder 40.

It extends to the right end of the leakage net 42 of the second processing cylinder 40, and the reduction conveyor 14 and the second processing cylinder 40 are communicated.
Therefore, the second product conveyed by the reduction conveyor 14 can be put into the second processing cylinder 40 along the guide port 38, and the second processing cylinder 40 can be used as a second processing cylinder. Therefore, the second item is not returned to the handling cylinder 20, and the working space of the handling cylinder is expanded accordingly, and a large amount of cereals charged at a time can be reliably processed.
[0020]
Moreover, as shown in FIG. 4, a plurality of feed blades 46, 46,. A communication port 43a is opened in the coarse net 43 on the side of the rear end portion of the cylinder 40, so that the residue left behind in the second processing cylinder 40 is thrown off to the handling cylinder 20 side. Processing is performed, or the dust is fed into the dust feeding port processing cylinder 21 from the rear end of the handling cylinder 20 for processing.
The rear end portion of the second processing cylinder 40 and the dust feeding port processing cylinder 21 are communicated with each other, so that the residue left by the feed blade 46 at the rear end portion of the second processing cylinder 40 is directly fed. It is good also as a structure splashed on the dust mouth processing cylinder 21. FIG.
[0021]
Further, as another form of the third processing cylinder 40, the front end portion of the second processing cylinder 40 is substantially coincident with the action start end portion of the crimp net 31 in a side view shown in FIG. It is possible to reduce the driving load by making it as short as possible.
A screw 47 shown in FIG. 5 is fixed instead of the blade-like teeth 41 to be planted around the second processing cylinder 40, and a cone cable 48 is used instead of the leakage net 42 corresponding to the screw 47. It is also possible to increase the speed of processing by laying the bag or the like backward.
[0022]
Therefore, even if a large amount of cereals is put into the threshing device 9 and shed in a large amount by the handling cylinder 20, a part of the threshing apparatus 9 is put into the second processing cylinder 40 more smoothly than the coarse net 43. The amount of wrinkles flowing along the crimp net 31 below the trunk 20 is reduced.
Furthermore, since the second product selected by the swinging main body 51 is put into the second processing cylinder 40 via the reduction conveyor 14 and is not put into the handling cylinder 20 side, the processing space on the handling cylinder 20 side can be kept wide. It is possible to reliably cereal cereals that have been transported in large quantities at a time, without generating scorpion grains or the like.
Further, the second processing cylinder 40 becomes a dedicated processing cylinder for processing the second product, and can reliably process the second product, and the dust feeding port processing cylinder 21 mainly processes the sawdust. In this way, the role of the processing cylinder can be shared, the processing capacity is increased, and the performance of the threshing device 9 is improved.
