You.

[0006]

In the illustrated example, a handling room 3 is framed by a front side plate 4, a rear side plate 5, a side frame 6, and the like. To handle 2
And a receiving net 7 is stretched along at least a lower half peripheral portion of the handling chamber, and is configured to be slidable and detachable. In addition to extending the feed chain 8 on one side of the handling room,
Grain stems are conveyed by a clamping rail 9 provided on the upper side.

The feed chain 8 and the chain rail 10 are configured so as to be able to swing open and close around a vertical support shaft 11 provided at the start end thereof. 10A is a chain support frame, and 11A is a column protruding from the machine base, which is a support stay protruding from the fixed side front side plate 4A of the handling room.
11A, the chain support frame 10A is rotatably mounted around the support shaft 11.

Further, a handling drum cover 12 which covers the upper part of the handling chamber 3
A cover rail 9 for the feed chain 8 is attached to the cover 12, and the cover 12 is constructed so as to be capable of swinging up and down in a vertical direction with a horizontal axis 13 in the front and rear direction as a fulcrum. The processing chambers 14 are arranged side by side on the opposite side of the handling chamber 3 from the feed chain 8 side, and receive the workpieces sent from the handling chambers 3 and process them while moving them rearward in the axial direction. The processing cylinder 15 is mounted on an interior shaft.

The processing chamber 14 has a processing cylinder receiving network 16.
Is stretched so as to allow the grain subjected to the shedding process to leak to the lower sorting section. The processing cylinder receiving net 16 is configured to be able to be pulled out toward the handling room 3 side, and is usually locked and held by the side frame 6 of the handling room 3. Dust chamber 1
Numeral 8 is a unit for receiving the processed material from the dust port 17 reaching the end of the processing chamber 14 and performing dust removal while transporting the processed material to the rear. A dust cylinder receiving net 20 is stretched. A dust outlet 21 is provided at the end of the dust chamber.

The cereal culm supplied into the handling room 3 is subjected to threshing by the handling cylinder 2. Processed materials such as straw chips and unprocessed particles generated in the handling room 3 are sent into the processing chamber 14 from the middle part, and are subjected to de-particle processing while being transported backward by the processing cylinder 15, and are further discharged from the processing chamber 14. It is sent into the chamber 18. Then, in the dust chamber 18, the particles are removed while being transported rearward by the dust cylinder 19. The grains dehulled in each of the chambers 14 and 18 leak from each of the receiving nets 16 and 20 to a lower sorting chamber, and are sorted by a swing sorting shelf 22. It is discharged out of the machine from the mouth 21.

The handling chamber 3 is configured such that the handling cylinder 2 and the receiving net 7 can be opened integrally with the lower sorting chamber and the processing chamber 14, that is, at the front end side of the handling chamber 3. And a longitudinal axis 24 provided on a body-side column 23 located on the processing chamber 14 side.
Is configured to swing open and close in the left-right and lateral directions with a pivot point. Further, the processing chamber 14 is configured so as to be able to swing open and close in the horizontal direction with the processing cylinder 15 and the processing chamber 3 coaxially with the processing chamber 3, that is, with the vertical axis 24 as a pivot.

The handling chamber 3 and the processing chamber 14 are configured to swing and open independently of each other, but as shown in FIG. 4, the handling chamber 3 and the processing chamber 14 are integrally formed. A means for swinging open and close may be employed. In the embodiment shown in FIGS. 5 to 7, the processing chamber 14 and the dust chamber 18 together with the processing cylinder 15 and the dust cylinder 19 are rotated left and right with the vertical axis 24 on the front side of the handling chamber 3 as a rotation fulcrum. It is configured to be able to swing open and close in the horizontal direction. In this case, feed chain 8
Swing open, the left and right sides of the handling room 3 are opened.

In the embodiment shown in FIG. 8, an entrance funnel 25 connected to the entrance of the handling room 3 is slidably accommodated in the handling room. If the swing opening and closing fulcrum of the handling room is set near the front side plate of the handling room, the inlet funnel projecting forward from the handling room will interfere with the harvested grain culm transporting portion of the cutting unit when swinging,
Although the entrance funnel had to be removed, the maintenance was poor, but according to such a configuration, the entrance funnel 25 is housed in the handling room when the handling room is open, so that interference with the reaping conveyance unit can be prevented. .

The inlet funnel 25 shown in FIGS. 9 and 10 is divided into a front funnel 25A and a rear funnel 25B, and the rear funnel 25B is fixed to the handling chamber 3 side.
The front funnel 25 </ b> A is pivotally mounted on the transport supply chain 26 side of the harvested grain culm so as to swing up and down around a horizontal rotation fulcrum O. An elastic transfer plate 27 such as a rubber dripping is provided between the front funnel 25A and the rear funnel 25B. Therefore, the handling room 3
When the front funnel 25A is upright at the time of opening, the interference of the rear funnel 25B with the side of the transport supply chain 26 can be prevented.

Further, an inlet funnel 25 shown in FIGS.
Is configured so that it can be slidably attached and detached so that it can be inserted and removed along the guide rail 28.
