DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine.

[0002]

2. Description of the Related Art Conventionally, Japanese Unexamined Utility Model Publication No. 1-16739 discloses a threshing apparatus having a threshing chamber having a handling cylinder mounted thereon, and a cereal culm from a supply side on one side of the threshing chamber to a discharge side. In a combine having a grain culm supply device for clamping and transporting the husk and a straw processing unit provided on the rear side of the threshing chamber, the rear end of the transport chain guide rail of the grain culm clamping and transporting device of the threshing device is provided with the threshing. A threshing device for a combine, which is rotatably fixed to the rear of the device, is described.

[0003]

In the above-mentioned known example, the grain stalk clamping and conveying device is made rotatable horizontally for the purpose of maintenance, but the structure is such that the starting end is horizontally rotated about the end. Since it is configured to be movable, the starting end is widely opened but the end is not opened. However, since the end portion is a portion which is taken over from the grain stalk holding and conveying device to the straw holding and conveying device, the end portion must be opened.
In addition, since the end portion has a structure that does not open, there is another problem that maintenance of the straw processing unit needs to be performed separately, which is troublesome.

[0004]

SUMMARY OF THE INVENTION In the present invention, the end portion is regarded as more important than the start end portion, and the end portion is opened, and at the same time, maintenance of the straw processing section can be performed at the same time.

[0005]

[0012]

Next, the operation will be described. Since the present invention is configured as described above, the cereal stalks mowed by the reaper 4 can be transported by the cereal stalk clamping and conveying device 2.
The husk is supplied to the threshing chamber 5 from the culm supply port 8 by the husk 8 and is threshed by the rotating drum 6 until the husk is discharged from the culm discharge port 9. Moving shelf 1
The threshing material in the threshing room 5 is transported toward the discharge side by the transfer oscillating shelf 10 and enters the wind selection chamber 13. Entering, blast Min 1
The first product enters the first conveyor 15 and is taken out of the machine, and the second product enters the second conveyor 16.

The grain stalks transported by the grain stalk holding and transporting device 28 are taken over by a straw transporting device 45, and are processed by a straw processing unit 26 at the rear side of the threshing chamber 5. In this case, even if straw is clogged in the straw conveying device 45, the straw can be easily removed by moving the upper cover 31 upward to move the straw conveying device 45 upward.

When the upper cover 31 which covers the upper part of the handling cylinder 6 is moved upward, the clamping rod 30 is moved upward. In this state, when the lock device is released, the transport chain guide rail 32 is connected to the fixed frame 35. Threshing device 4 which is rotated outwardly around the mounting portion of
Moving side plate 37 and chain cover 3 of supply and transport chain 29
8 is also rotated outward to open the side of the threshing chamber 5 and the side of the wind selection chamber 13 so that maintenance of the threshing chamber 5 and the wind selection chamber 13 can be easily performed.

When the handling cylinder 6 is rotated about the shaft fitting 43, the upper surface of the transfer swing shelf 10 and the swing sorting frame 14 are left, leaving the processing cylinder 21 and the dust discharge cylinder 24. Since the air selection chamber 13 on the upper surface is opened, these maintenance operations are facilitated. Further, since the straw processing unit 26 rotates rearward, maintenance can be easily performed simultaneously with the side of the threshing chamber 5 and the side of the wind selection chamber 13. In some cases, maintenance work may be performed by detaching the transfer swing shelf 10 provided below the threshing room 5 from the swing frame body.

[0016]

[Effect] The present invention includes a threshing device having a threshing chamber which axis has Jikuka the longitudinal direction of the threshing drum, grain toward the left or right is provided on one side supply side or et emissions side of the threshing chamber and culms supply device for clamping conveying the culms, the combine having a straw discharge unit provided towards rear discharge side of the threshing chamber, thien cover provided outside of the supply device, the said threshing chamber air A part of the selection chamber is surrounded by an openable and closable side plate, and the feeding device, the chain cover, and the side plate are combined so as to be horizontally rotatable so as to open integrally outward. Since the end portion of the device 28 can be rotated, a place where a clogged grain culm easily occurs between the end portion of the grain culm conveying device 28 and the start end of the straw conveying device 45 can be easily opened and maintained. Not only the front end of the transport chain guide rail 32 Supported on a solid, an effect that causes smooth take over the culms from reaper 4 to grain 稈挾 lifting transfer apparatus 28. And the said straw processing part is the anti-grains
Since the threshing chamber is configured to be rotatable substantially horizontally and rearward about the storage 28 side, when the threshing chamber is opened, the handling cylinder does not interfere, so that there is an effect that the threshing chamber and the straw processing unit can be maintained at the same time.
