But of course, threshing device 3
Arrangement is arbitrary based on the traveling direction of the combine, and it may be installed.

[0016]

[Operation] Next, the operation will be described. Since the present invention has the above-described configuration, the grain culm is fed by the grain culm transporting and feeding device 34.
0 is supplied into the threshing chamber 5 and threshed by the handling barrel 10 which rotates until it is discharged from the grain culm discharge port 41, and the threshing leaks from the handling net 11 and the transfer section 22 of the swing rocking selection frame 21
It drops upward, is transferred toward the discharge side by the transfer protrusions 23 of the transfer unit 22, enters the wind selection chamber 20, and the threshing chamber 5
The cereals inside enter into the air selection chamber 20 through the discharge port 42, and the sorting wind and the swing sorting frame body 2 that are blown by the blower Karasu 26.
The first item enters the conveyor 27 and is taken out of the machine, and the second item enters the second conveyor.

Then, the upper cover 31 covering the upper part of the handling cylinder 10 is moved upward, and the grain culm conveying and feeding device 34 and the moving side plates 3 on the sides of the threshing chamber 5 and the wind selecting chamber 20 are operated by any means.
3 is moved to the threshing chamber 5 on the side where the grain culvert passage 30 is located.
Since the opening 43 is formed by opening from the side portion of the wind chamber to the side portion of the wind selection chamber 20, maintenance work can be easily performed.

In this case, an opening 43 is formed by hanging from the side of the threshing chamber 5 on the side where the grain culm passage 30 is located to the side of the wind selecting chamber 20.
Since the structure is formed and opened, the strength of the rear plate 7 and the handling net mounting middle plate 13 becomes insufficient, causing noise and vibration, and increasing the plate thickness to secure rigidity. However, in the present invention, an extension reinforcing member 47 is provided between the dust side plate 46 fixed to the machine body and the left side of the rear plate 7 and the handling net mounting middle plate 13 in the present invention. Since it is provided, strength is secured, noise and vibration are prevented, and the weight is reduced.

The handling net 11 is attached to a frame body 12 consisting of an arc-shaped front and rear frame 14 and a horizontal frame 15 in the front-rear direction which are substantially concentric with the handling barrel 10, and the frame body 12 is attached to the front plate 6 and the handling net. Middle plate for mounting 1
Since it is mounted between the front and rear plates 6, the front plate 6 and the handling net mounting middle plate 13 are connected by the frame 12, and the rigidity of the skeleton frame 48 of the threshing device 3 is further improved. Further, when the frame 12 of the handling net 11 is attached to the chain guide rail 37 of the grain culm conveying and supplying device 34 to be detachable,
The frame 12 is positioned between the front plate 6 and the handling net attachment middle plate 13 to perform a width determining action, and the engagement hook 17 engages with the engagement pin 18 to position the handling net 11. Also, the frame 1
When 2 is removed, there is no obstacle between the front plate 6 and the handling net attachment middle plate 13, and maintenance can be easily performed.

[0020]

[Effect] According to the present invention, the front plate 6 which hangs the front end portion of the handle shaft 9
And a rear plate 7 for mounting the rear end portion of the handling barrel shaft 9, and an intermediate plate for attaching a net which is located between the front plate 6 and the rear plate 7 and which fixes the rear side edge of the net 11. 13, the side edges of the rear plate 7 and the handling net attachment middle plate 13 on the grain culm conveying / supplying device 34 attachment side extend from the rear plate 7 to the handling net attachment middle plate 13. Since it is a threshing device connected by 47, it is possible to secure the strength on the side of the grain culm transporting and feeding device mounting side of the handling net mounting middle plate 13 and prevent noise and vibration.
Further, there is an effect that the weight can be reduced.
Further, according to the present invention, the handling net 11 is a threshing device in which the front end thereof is detachably fixed to the front plate 6 and the rear end thereof is detachably fixed to the handling net mounting middle plate 13, respectively. The net-mounting middle plate 13 and the front plate 6 can be connected to each other, and the strength can be improved.
