SUMMARY OF THE INVENTION As described above, Japanese Utility Model Laid-Open No. 1-1
No. 67839 , Microfilm No. 1-1678
No. 40 microfilm, Japanese Utility Model No. 2-83726
In the configuration disclosed in the microfilm , the supply transport chain is configured to rotate outward about a vertical axis attached to the rear side surface of the threshing device.

Therefore, when the supply and transport chain is turned outward, the front of the supply and transport chain is separated from the side of the threshing apparatus, and the front side surface of the threshing apparatus is opened. However, the rear side surface of the threshing device, which is located on the vertical axis, is obstructed by the rear portion of the supply transport chain, and cannot be largely opened. As a result, even if the supply and transport chain is rotated and opened, maintenance of the rear side of the threshing device, which tends to generate a large amount of straw waste, cannot be performed sufficiently and easily, and the efficiency of the maintenance work is low. Was.

[0007] Further, it is necessary to maintain an appropriate relative position between the end of the transfer conveyor and the starting end of the supply transfer chain located on the upper side of the supply and transfer chain in order to transfer and transfer the grain culm. However, in the above-described configuration of the related art, when the supply transport chain is rotated outward, the supply transport chain is rotated about the vertical axis of the rear portion, and the start end of the supply transport chain is greatly increased from the end portion of the takeover transport device. Because they are separated,
When the supply / conveying chain is rotated inward to return to a state in which normal threshing work is possible, the delicate positional relationship between the start end of the supply / conveying chain and the end of the take-over / conveying device is likely to be out of order.

As a result, the transfer of the grain culm from the transfer conveyor to the supply transfer chain cannot be performed stably, such as spilling of the culm during the combine operation, and the threshing operation cannot be maintained smoothly. .

[0009]

The present invention employs the following technical means in order to solve the above-mentioned problems. That is, as described in claim 1, in a threshing apparatus for threshing a grain culm supplied from the reaping unit 4 via the takeover transport device 33 while pinching and transporting the culm by the supply transport chain 12 and the clamping rod 11. , Upper cover-1 of the threshing apparatus 1

FIGS. 9 and 10 show that the drive gear 31 of the supply / conveyance chain 12 is replaced by the rear passive gear 16.
This shows an embodiment provided at the end of the transfer chain guide rail 14, in which case a transmission shaft 41 provided on the gear case 40 serves as a drive shaft of the drive gear 31, and
The straw conveying device 42 is driven by another transmission path.

Next, the operation based on this configuration will be described. The cereal culm is supplied from the cereal culm supply port 8 into the threshing chamber 5 by the cereal culm holding / conveying and feeding device 10 and is threshed by the rotating handling drum 6. Is first taken out of the machine after entering the conveyor. The grain stalks conveyed by the grain stalk clamping and conveying supply device 10 are taken over by a straw conveying device 42 and processed by a straw processing section provided on the discharge side 3 of the threshing chamber 5.

The upper cover for covering the upper part of the handling cylinder 6 is provided.
If the operating handle 58 of the chain rail lock device 52 is operated in this state, the engaging hook 56 is disengaged from the engaging shaft 55, and the transport chain guide rail is moved. 14 can be pivoted outward about the engagement longitudinal axis 24, and maintenance of the supply and transport chain 12 can be performed.

At the transition portion between the end portion of the grain squeezing and feeding device 10 and the start end portion of the straw conveying device 42, grain stalks are likely to be clogged, but the transport chain guide rail 14 is engaged vertically. It can be easily removed by turning the shaft 24 around the outside. Since the moving side plate 35 of the threshing apparatus 1 and the side cover 36 of the supply transfer chain 12 are attached to the transfer chain guide rail 14, the transfer chain guide rail 14 is rotated to allow the transfer chain guide rail 14 to rotate. The cover 36 and the movable side plate 35 are rotated outward, and the side of the threshing chamber 5 and the wind selection chamber 1 are rotated.
3 is opened so that maintenance of the threshing room 5 and the wind selection room 13 can be easily performed.

In this case, the mounting frame 18 of the transport chain guide rail 12 is rotatably mounted on a vertical support rod 23 of a support frame 22 fixed to the machine body frame 2, and The upper horizontal rod 25 of the support rod 23 is parallel to the transport chain guide rail 14 at the time of storage, and the rear end of the upper horizontal rod 25 is fixed to the front member 26 of the threshing room 5, and is intermediate between the upper horizontal rod 25. The part has an oblique reinforcing frame between the threshing chamber 5 and the front member 26.
Since the frame 27 is provided, the load when the transfer chain guide rail 14 rotates is strongly supported by the support frame 22 and the reinforcing frame 27. Therefore, even if the movable side plate 35 of the threshing apparatus 1 and the side cover 36 of the supply and transport chain 12 are attached to the transport chain guide rail 14, they can be smoothly rotated.

When the transport chain guide rail 14 is rotated toward the original position about the engaging longitudinal axis 24, the engaging body 51 provided on the transport chain guide rail 14 causes the threshing device 1 to rotate. The engaging hook 56 of the locking device 52 engages with the engaging shaft 55 to fix the transport chain guide rail 14. In this case, since the lock guide 59 having the Y-shaped guide groove 60 is provided on the shaft 57 located above or below the engagement hook 56, the engagement hook 56 engages with the engagement shaft 55. Before the engagement hook 55 enters the guide groove 60 and the engagement hook 5
6 is guided toward the engagement shaft 55, so that the engagement is ensured.

Since the front end of the transport chain guide rail 14 is firmly supported by the support frame 22, the front end of the transport chain guide rail 14 is always at a fixed position with respect to the take-over transport device 33. Since it is located, the cereal culm from the reaping unit 4 can be smoothly transferred to the cereal culm holding and feeding device 10.
