Further, at the lower part in front of the handling cylinder 20, the insertion port 32 is opened in a range from the side position of the feed chain 7 to the right side position of the handling cylinder 20, and the tip side of the grain pod is introduced. Further, an arc-shaped support frame 35 is disposed on the lower surface side of the handling cylinder 20, and a leaking body, which will be described later, is laid on the support frame 35, so that the wrinkles and the like shed from the handling cylinder 20 are placed downward. Is leaking onto the swinging main body 51.

  Further, the dust supply port processing cylinder 21 is disposed above the left end (the Glen tank 12 side) of the swinging main body 51 in a front view. The front part of the dust supply port processing cylinder 21 is wrapped with the rear part of the handling cylinder 20 in a side view, and the rear end part extends to the rear end part of the handling chamber. A spiral screw 36 is fixed around the dust feed processing cylinder 21, and a cone cave 37 is disposed along the lower side of the rotation trajectory of the screw 36. Is processing. However, instead of the screw 36 and the cone cave 37, it is also possible to configure with a tooth handling and a crimp net.

  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. The second processing cylinder 40 is disposed in parallel with the handling cylinder 20 and the dust feeding port processing cylinder 21, and is formed substantially equal to the outer diameter of the dust feeding port processing cylinder 21. Further, in the side view shown in FIG. 4, the rear end portion of the second processing cylinder 40 is positioned immediately before the front end portion of the dust feeding port processing cylinder 21, and the front end portion of the second processing cylinder 40 and the front end of the handling cylinder 20 are arranged. The start position of the action of the second processing cylinder 40 is matched with the front end of the handling cylinder 20.

  In addition, blade-shaped blade teeth 41, 41,... Are planted around the second processing cylinder 40, and the rotation speed is increased so as to surely loosen the swarf and remove the branch leaf of branch leaf-attached grains. I have to.

  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 or the like is 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.

  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 the generation of sag particles.

  In addition, the rotation direction of the second processing cylinder 40 is opposite to the rotation direction of the handling cylinder 20 and the dust feeding port processing cylinder 21. 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.

  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.

  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. A guide port 38 is fixed to the lower left of the end portion, and the end portion of the guide port 38 is connected to the end of the guide port 38. 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.

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.

  Further, as another form of the second processing cylinder 40, the front end portion of the second processing cylinder 40 is made to substantially coincide with the operation 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.

  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.

  Then, the shavings and the like that could not be processed by the second processing cylinder 40 are returned to the rear part of the handling cylinder 20 as described above, and the sawdust and branching lump adhering grains that have not been separated from the leakage treatment process on the handling cylinder 20 side are sent. It is thrown into the front part of the dust-feed port processing cylinder 21 through the dust port. The unprocessed material that has been thrown in handles a large amount of swarf backward while processing entangled swarf, leaking scabs contained in the swarf, or processing spikes, etc. go.

  As shown in FIG. 2, in the present invention, a waste discharging mechanism 90 is formed at the rear end portion of the dust feeding port processing cylinder 21. That is, as shown in FIGS. 7 and 12, the waste discharging mechanism 90 includes wings 91, 91, which are long plate bodies on the outer peripheral surface of the rear end portion of the dust-feed port processing cylinder 21. A fan projecting in the radial direction and a substantially annular cover 92 covering the outer peripheral side of the rotation locus of the wing 91 are formed.
