A dust removal treatment chamber 28 having a dust removal treatment cylinder 27 mounted on the core is configured and provided. The dust removal processing cylinder 27 receives the processed material from the dust discharge passage portion 10 of the handling chamber 3 and processes it backward, and the second processing cylinder 24 processes the second processed material from the second reduction device 30. The second processing cylinder 31 that receives the processed material from above and conveys it forward is disposed below the second processing cylinder 24 and the dust removal processing cylinder 27. 2 A configuration is provided in which the processing chamber 32 is pivoted. In this configuration, the leakage from the receiving net 29 of the dust removal processing chamber 27 is processed while being sent forward by the second processing cylinder 31, and is leaked to the start end side of the swing sorting shelf 34 for sorting. For example, the scattering of No. 3 is reduced, and the second reduced product can be processed by the upper and lower double No. 2 processing cylinders 24 and the second processing cylinder 31 so that the branch infarct can be removed quickly and easily.

  In the case of the above configuration, the receiving net 26 of the second processing chamber 25 is perforated, and the receiving net 33 of the second processing chamber 32 is perforated in the range 33a from the position of the inner side plate 7 to the end side of the handling chamber, In the range 33b extending from the position of the inner side plate 7 to the start end position, no leakage is made, so that the leakage from the dust removal processing chamber is sent from the chaff sheave 34b of the swing sorting shelf 34 to the front start end side and onto the transfer shelf 34a. It is possible to perform the sorting process by leaking, and the above-described object effect can be achieved.

  In addition, in FIG. 5, by making the mesh of the receiving net 26 of the second processing chamber 25 larger than the mesh of the receiving net 33a of the second processing chamber 32, the removal rate of the second item is reduced, The branch branch can be removed. Conversely, if the mesh size of the receiving network 26 is smaller than the mesh size of the receiving network 33a, the branch infarct can be reliably removed.

  Further, as shown in FIG. 7, the receiving network 33 of the second processing chamber 32 has a non-hole 33b in the entire range from the start end side to the end side, and the transfer of the swing sorting shelf 34 from the start end only from the end discharge port 35. It can also be set as the structure which discharges and falls on the shelf 34a, and according to this, the increase in deflation can be prevented and the branch infarction can also be removed reliably.

The configuration is as follows. The waste from the dust processing chamber is quickly combined with the leakage from the second processing chamber by the continuous processing teeth 31b, and processed by the discontinuous processing teeth 31a. Therefore, it is possible to reliably remove the branch limbs without increasing the number of limbs. Further, in the embodiment shown in FIG. 10, the mesh 26 a of the second processing chamber receiving net 26 is made larger than the mesh 33 a of the second processing chamber receiving net 33, and the tip of the processing tooth 24 a of the second processing cylinder 24 is used. By making the peripheral speed faster than the peripheral speed of the distal end of the processing tooth 31a of the second processing cylinder 31, the second processed material is quickly leaked and merged into the second processing chamber 32 and again by the discontinuous processing tooth 31a. By performing the degranulation treatment, the branch infarction can be removed efficiently and reliably.

  Moreover, as shown in FIG. 11, the 2nd process cylinder 31 can also be made into the continuous process tooth | gear 31b from the start end to a termination | terminus. In this case, when the entire second processing chamber receiving net 33 is configured as a non-hole 33b, it is desirable that the second processing cylinder 24 is a discontinuous processing tooth 24a and the receiving net 26 is a perforated hole 26a. Further, as shown in FIG. 12, the receiving net 33 of the second processing chamber 32 has a perforation in a range 33a from the position of the inner side plate 7 to the end side, and in a range 33b extending from the position of the inner side plate 7 to the start end side position.
