[0010]
The sorting path of the threshed handling wholesale is that the grain and unprocessed material generated in the handling chamber 8 leaks from the receiving net 17 and becomes a handling wholesale, on the swing sorting body 30 that swings back and forth. While passing through the sieve selection while falling and sieving to the starting end side of the chaff sheave 31 arranged on the lower side, the cereals are mainly gathered in the recovery area 33 while separating the cerealized grains. The reduced product mixed with the branch leaf adhering grains and a small amount of single grains is dropped into the second collection area 35 arranged at the rear and sorted into a path for collection, and dust such as sawdust is provided in front of the sorting section C. This is a sorting path that is blown away in the direction of the arrow a by the sorting air of the fan 36, sucked by the suction fan 37 disposed at the rear of the machine body, and discharged outside the machine.
[0011]
The good grains separated by the sorting section C are taken out of the machine by the first conveyor 40 and temporarily stored in the Glen tank 43 arranged on the right side of the machine base 21, but most of the above-mentioned branch raft adhering grains are untreated.

First, the outer cover 53 of the transfer case 10 is removed, and the input shaft 2 is extracted in the direction indicated by the arrow B, and the bevel gear 55 inserted into the spline groove 57 is inserted. The guide link 67 is supported by a bearing 68 to maintain the posture before extraction. After separating the input shaft 2 in this way, the connecting bolt 65 connecting the transfer case 10 and the processing cylinder 7 is detached, and passes through the processing cylinder axis 1 obtained by dividing the wall plate 11 formed of a single plate. Since the insertion and removal in the direction of the arrow C along the connection surface 15 is possible, the front surface to be connected is opened to facilitate the inspection and maintenance in the processing chamber 6.
[0015]
FIG. 3 is a perspective view of the processing apparatus connected to the second cereal cylinder, and the outer appearance of the processing apparatus attached to the main part side view of FIG. The cylinder 60 is inserted, and the mounting frame 63 is welded to the outer peripheral surface to be contacted, and fastened with the fixing bolt 70 so as to be orthogonal to the second lifting cylinder 5. In addition, the cleaning opening 13 is opened in the wall plate 11 that covers the outer end surface of the processing chamber outer cylinder 60, and the cleaning lid 71 is detachably attached with a butterfly bolt 74 to be used as a confirmation window when an abnormality occurs. The first means. The next step is an operation for removing clogging in the processing chamber 6. As described above, in order to remove the input shaft 2 together with the outer lid 53 and insert and remove the wall plate 11, the transfer case 10 and the processing are performed. The outdoor cylinder 60 is screwed with a connection bolt 65, and the connection surface 15 is opened by detachment, which is a second means of inspection and maintenance for removing foreign matter.
[0016]
FIG. 4 is a front view showing the arrangement of the processing chambers and the handling chambers. The procedure for extracting the processing cylinder 6 from the handling chamber side will be described. The receiving net 17 forming the handling chamber 8 is divided into a mesh frame 72a. , 72b, and is attached to the position of the chain line so as to be freely detachable in the direction indicated by the arrow E. The arm 75 is extended from the rotation fulcrum P provided on the upper frame 73 to support the handling cylinder 27, An open structure is provided that is attached to the movable frame together with the presser foot support 95 that engages with the feed chain 25 and is raised in the direction of the arrow D to cope with abnormal phenomena such as clogging occurring in the handling chamber 8. In this way, the treatment chamber 8 is opened, so that the processing cylinder 7 is fitted and removed from this space portion, and is used as a third means of inspection and maintenance for removing or repairing clogging.
[0017]
The processing cylinder 7 is taken out by releasing the handling cylinder 27 and the net frames 72a and 72b, and then removing the fastening bolt 76 of the bearing 61 provided on the terminal end side of the processing chamber outer cylinder 60, so that the processing cylinder is integrated with the support shaft 3. 7 is extracted in the direction of the arrow, and the processing cylinder boss 58 is removed from the shaft end of the input shaft 2 to remove dust on the rocking sorter 30, and the mixed grains are scattered outside the machine. On the other hand, it is a configuration that makes it easy to carry out inspection and maintenance such as parts replacement by taking it out of the machine.
[0018]
FIG. 6 is a cross-sectional view showing another embodiment of the second reduction device. The structure of the switching valve and the dispersion blade will be described using the front view of FIG. 7 together. The start end of the processing chamber outer cylinder 60 formed without holes. Equipped with a switching valve 81 that can be opened and closed on the side, and has a switching structure in which the processing action that passes through the processing chamber 6 and the non-processing action that opens and discharges the start end side, the bottom is opened and inserted into both sides. The valve rod 83 is provided in front of the processing chamber outer cylinder 60, and is used as a rotation center of the fixed switching valve 81. A lever 85 is connected to the end of the shaft, and is connected to a wire 86 that is opened and closed from the side of the machine body. This is an adjustment structure (not shown).
[0019]
In order to perform the opening / closing operation, the pulling spring 87 acting in the normally closing direction is extended by pushing and pulling the wire 86 described above, and the switching valve 81 opens in the direction of the arrow to face the inside of the swinging sorter 30. Since the reduced product is guided and discharged before passing through the processing chamber 6 to avoid the impact of the processing teeth 62, grain damage such as varieties that are easy to tear is prevented, and it flows down toward the center of the selection width. Therefore, the switching structure is made to reduce the deviation of the deposit that causes the sorting abnormality. Moreover, it is the structure of another Example which can be utilized also for the cleaning port which removes the residual grain in the said processing chamber 6, and can prevent mixing and cleaning.
[0020]
