44-1 is provided, and a drive mechanism 54 for transmitting the drive while supporting the left-side grain culm discharging arm 12 on the left-side grain culm discharging means 12a side is supported above the both shafts 11 and 44-1. Since it is the grain culm discharging device in the harvesting and binding machine, a horizontal carrier for transporting the grain culm bundle is not required, and the binding device 7 as a whole can be configured compactly, and the harvesting and binding work can be performed. It can be done efficiently and the left culm discharge means 12
Since the a-side drive mechanism 54 can be firmly supported, the grain culm can be reliably discharged in a stable state.

[0031]

As described above, according to the present invention, the grain culm bundle is moved to the left in the tying device having the tying needle and the knotting portion and having the tying passage in the front-back direction of the machine body. The left culm discharging means for discharging the culm and the right culm discharging means for discharging the culm bundle in the right direction are provided on the left and right sides so as to sandwich the binding passage, and the culm bundle is selected on the left side or the right side. And a clutch shaft for driving the binding needle, the input shaft for driving the binding device and the clutch shaft for driving the binding needle are interlockingly connected through an endless chain, and a constant short interval with respect to the endless chain. The clutch shaft and the knot shaft are interlockingly connected via a binding transmission chain disposed below and the grain stems are received within the overlapped range in each winding range of the endless chain and the binding transmission chain. Door mounting shaft with door attached , Arranging a needle drive shaft for driving the binding needle, and supporting a drive mechanism for driving the transmission while supporting the left grain culm discharging arm on the left grain culm discharging means side at the upper part of both shafts. Since it is a grain culm discharging device in a characteristic cutting and tying machine, the whole tying device can be configured compactly, and the cutting and binding work can be efficiently performed, and the left grain culm discharging means side is driven. Since the mechanism can be strongly supported, the release of the grain culm can be reliably performed in a stable state.

Further, while the supporting structure of the drive mechanism for transmitting and driving while supporting the grain culm discharging arm is simple, the binding device as a whole can be made compact and the cutting and binding work can be performed efficiently. Is what you can do.

Further, in the conventional apparatus, a belt-shaped horizontal carrier is provided at the rear of the bundling device to sequentially transfer the grain culm, so that the length of the machine body in the front-rear direction is long. Therefore, the grain culm is often damaged and the operation of the machine is difficult. However, according to the present invention, since the lateral carrier is not required and the machine can be configured compactly, It is possible to prevent the bundle from being damaged.

In the case of switching the discharge direction of the grain culm bundle, the conventional one could not switch until the horizontal conveyance by the horizontal conveying body is completed, but since the present invention can directly discharge the grain culm bundle, The discharge direction can be switched in a short time.

Further, according to the present invention, since the grain culm discharging means are provided on both the left and right sides of the machine body, the balance of the machine body on the left and right is improved.
