The screen support portion 23s on both sides is bolted to the movable selector frame 2 by the bolt 23ν^°. The second mounting bracket is fixed to the swinging portion 20 of the pendulum 20 to release the swinging sorting frame. After the fixing of the first bracket 23, as shown in Fig. 14, the scanning members 80, 8〇, 8〇$ @ and Fig. 15 are not provided, the upper portion will be mounted, and the protruding portion 89 can be swung from: to the swinging sorting frame 2 Pull out the swing arm 88 to separate the drive 23 201134384 and remove the -t帛23. In addition, the long hole of the swing sorting frame 2 () includes the hole portion of the example as shown in the figure. In addition, in the case where the concentrating plate 98 from the transfer frame 22 to the first = 23 is installed as in the present embodiment, the concentrating plate 98 is mounted as detachable and detached as shown in FIG. The counter-98 can be taken out from the inspection 〇ns, and the concentrating plate 98 can be first removed. 'The first sieve 23 can be removed upwards after removing the obstruction of the concentrating plate%. In addition, the tension is placed on the lower side of the detachment chamber U. The end portion of the receiving net 15 on the side of the entry bar portion 9 can be configured to be engaged and disengaged by the net (4) members of the (four) and the like in the front-rear direction (4) on the lower side of the receiving net 15 When the mesh fixing member 15U is transversely cut to the inspection port (1) in a state where the feed chain 13B is opened, the net-fixing member 15U becomes the first (4) loading and unloading port. Therefore, in this case, as shown in FIG. and circle I, the shape of the member 15U is set to be larger than the front side and the rear side of the inspection port (1) and overlap with the inspection σ us. Engaged in the receiving portion (5) of the end portion on the side of the feed chain portion 9 and on the side of the feed chain portion 9 which is subjected to (4) in the middle portion of the front and rear direction of the inspection port... The bottom of the song is ideal for the shape of the 15th shape of the 11th-shaped f-curve. After the formation of the (four) curve::: and the end of the feed chain 15 on the side of the feed chain, the delicious (1) will Since the first screen 23 is taken out to the outside, the work space is increased from the loading and unloading work space of the inspection port m. (Others) (A) In order to increase the processing efficiency of the rear side of the barrel 1 , as shown in FIG. 26 , the division of the barrel 10 into the front barrel 1 and the rear barrel 102 and the rear barrel 102 are compared. The pre-granulation drum ι〇ι speed is fast or the rotation speed is high, although it is known in this case, not only the rods or dust are liable to adhere to the lower part of the barrel 12 after being in the -f帛23, but also strong degranulation. When the drum winds up, the processed material on the first screen 23 is biased to one side in the left-right direction, resulting in a decrease in the sorting energy. Therefore, in at least the rear direction range of the 23rd, the cleaning members 8〇, 8〇, ribs are provided at least in the lower portion of the rear descaling drum 102. The removal efficiency of the sticks or the like adhering to the first screen 23 is improved, or the cleaning member 80 is removed. The reciprocating movement of 80, 80, ... makes the treatment on the first screen 23 on average ideal. (B) As shown in Fig. 29, the mesh of the hole of the receiving net 15 is larger than the holes 15 1 a and 152 a located on the rear side of the receiving net 15 than the holes 15 1 a and 152 a located on the front side. When the efficiency of the grain treatment is increased, the recovery efficiency of the grain is increased, but the passage of the net 15 such as the shoulder is promoted, so that the rod or the like is easily attached to the first poem 23. Therefore, the above-mentioned clear members 80, 80, 8〇.. are provided, and the mesh of the upper part of the cleaning member 8〇, 8〇, 8〇..· which is only received by the net ls is larger than other parts. That is, in the case of illustration, it is preferable that the mesh of the hole of the mesh 15 is located at the rear side of the receiving net 15 and the holes Μα to Uld and l52b to 152d are larger than the hole 15^ located at the front side. =,, although the swarf swarf is easy to pass from the larger 4 knives of the mesh of the hole of the mesh 15, but the cleaning member rib, 80... is provided below the passing position, thereby effectively preventing Adhesion to the swarf or the like of the first sieve 23. In addition, even if the mesh of the hole of the receiving net 15 is made larger, in the center of the present embodiment, the inner peripheral surface of the circumference 15 has a field 25 201134384 which is formed by the partition portion 15 d in the circumferential direction. It is preferable that the meshes of the holes 151c and 152c in the vicinity of the front portion of the partition portion 15d are made relatively small. Since the pressure of the threshing tooth is likely to be present in the vicinity of the front portion of the partition portion 15d, the dislocation rate is high. Therefore, if the mesh of the hole 151c 1 52c of the receiving mesh 15 is large, not only the rate of threshing is lowered, but also swarf, etc. The net 15 is partially concentrated by the throughput. Further, in the present embodiment, the second processing chamber 4 is opened on the side of the side of the barrel roller 〇, and the opening portion is located below the side portion of the receiving cymbal 5, and is separated from the side portion of the 1-5. The structure in which the grain processing material is supplied to the second processing chamber is shown in detail in Figs. 27 to 29, and the receiving mesh 5 is the upper portion 152 which is located above the side portion of the second processing chamber 40 on the side of the barrel 10 The lower portion 丨5丨 located below the upper portion 152 is connected to the divided structure, and only the lower portion 151 does not have the hole 15 near the front of the partition 15d. The mesh is large and relatively small, and the upper portion 152 is not only the hole 152c near the front of the partition portion I5d, but only the holes 152b to 152d of the upper portion of the cleaning members 8〇, 8〇, 8〇... The aperture 52a located at other locations makes the mesh large. That is, in the case of the display mode, it is preferable that the mesh of the holes 152b to 152d located on the rear side of the receiving net 15 is larger than the mesh of the hole 152a located on the front side. The filtrate from the lower portion 151 is directly supplied to the first sieve 23, so that the mesh of the hole 151c near the front portion of the partition portion 15d of the lower portion 5J is not made larger than the ratio of the branch of the first object. Reduce 'good to maintain the accuracy of the selection. Further, the filtrate from the upper portion 152 is guided to the second processing chamber 40 and returned to the front side of the swing sorting frame 2, so that concentrated supply of chips or the like below the front side of the partition portion 15d is less likely to occur. In this case, the mesh of the hole of the upper portion 152 is located in the upstream side of the second processing chamber 40 in the upstream direction, and the hole 152b is larger than the hole 152b to 152d on the side of the flow downstream 26 201134384, from the upper portion 152. The supply amount of the threshing treatment in the exhaust chamber 40 is more than the downstream side in the transport direction, and can be processed in a wide range by the processing path of the second processing chamber 4 . ^ ' can improve the processing efficiency of the first processing chamber 40. & (1) In the above example, only the first screen 23 is provided with the cleaning member, and the upper member is attached to the upper portion.
