[0001]

TECHNICAL FIELD The present invention relates to a combine threshing apparatus.

[0002]

2. Description of the Related Art Conventionally, a combine threshing apparatus has
A supply transport chain called a feed chain and a clamping rod are provided vertically facing each other along a handle formed in the outer portion. In the combine operation, the culm to be planted in the field is mowed by the reaper, and the cereal culm is supplied to the supply transfer chain start end by the takeover transfer device,
The supplied stem portion of the grain culm is clamped between the feeding and transporting chain and the clamping rod, and the tip is inserted into the threshing chamber while being transported rearward, and the barrel is gripped at the tip of the grain culm. And a threshing process by giving a threshing action.

[0003] However, as described above, the supply / conveying chain and the pinching rod are provided along the handle on the outside of the threshing device, so that maintenance such as inspection and cleaning of the inside of the threshing device can be easily performed. The upper cover of the threshing device
A technique has been considered in which the feeding and transporting chain is configured to be movable upward and the supply and transport chain is configured to be rotatable and openable to the outside of the threshing device.

[0004] For example, Japanese Utility Model Laid-Open No. 1-167839,
Japanese Unexamined Utility Model Publication No. 1-167840 discloses a threshing apparatus for threshing while holding and transporting a grain stalk by a supply / conveying chain and a pinching rod, wherein an upper cover of the threshing apparatus and the pinching rod are integrated. And can be moved upward,
A combine threshing apparatus is disclosed in which the supply and transport chain is configured to be rotatable outward about a vertical axis attached to a rear side surface of the threshing apparatus.

[0005]

SUMMARY OF THE INVENTION As described above, Japanese Utility Model Laid-Open No. 1-1
In the configurations disclosed in Japanese Patent Application Publication No. 67839 and Japanese Utility Model Application Laid-Open No. 1-167840, the supply / conveying chain is configured to rotate outward about a vertical axis attached to the rear side surface of the threshing device. Therefore, when the supply transport chain is turned outward, the front portion of the supply transport chain is separated from the side of the threshing device, and the front side surface of the threshing device 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 / conveyor chain is rotated and opened, the maintenance of the rear part of the threshing apparatus cannot be performed sufficiently and easily, and the efficiency of the maintenance work is low. In addition, it is necessary to maintain an appropriate relative position between the end portion of the transfer conveyor that is located on the upstream side of the supply transfer chain and the start end of the supply transfer chain in order to 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. When the supply / conveyor chain is returned and rotated inward to return to a state where normal threshing work can be performed, the delicate position between the start end of the supply / conveyor chain and the end of the transfer / conveyor device is determined. Relationships tend to be out of order.

[0007] As a result, the culm spills during the combine operation, and the transfer of the grain culm from the transfer conveyor to the supply transfer chain cannot be performed stably, and the threshing operation cannot be maintained smoothly. .

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 / supplying device 10 and is threshed by the rotating handling cylinder 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.

Further, although grain culm tends to be clogged at the transition portion between the end portion of the grain squeezing and conveying device 10 and the start end portion of the straw conveying device 42, 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.

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 conveyor chain guide rail 14 is rotated around the engaging longitudinal axis 24 toward the original position, the engaging body 51 provided on the conveyor 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.
