In such a bundling culm discharge operation, since there is a regulating body 5 protruding into the discharge path 3 on the starting end side of the bundling culm discharging device 43, the bundling culm from the bundling device 1 is discharged onto the regulating body 5. Ru. Then, regulatory body 5
is elastically deformed by the load of the bundled culm and lowers to a position below the lugs of the endless transport body 45 and the auxiliary transport device 65, and the bundled culm is transported later by the endless transport body 45 and the auxiliary transport device 65. and,
When the bundled culms are removed from the regulating body 5, the regulating body 5 returns to its original state due to its elastic force, that is, it protrudes into the discharge path 3 and returns to the plant base side of the unbound culms that are being collected in the culm passage 23. This prevents the unbound culm from protruding outside the culm passage 23 on the plant side.

In particular, when the bundled culms are released into the field in an upright state, the tip side is tied, so the opening on the stock side becomes large, and the stock side of the untied culm tends to protrude from the culm passageway 23. Therefore, unbound culms and tied culms often become entangled, but the regulating body 5 prevents the unbound culms from protruding and separates the unbound culms from the tied culms. Therefore, the unbound culms are prevented from being taken out, and the releasing posture of the bound culms is maintained well.

In addition, in Figures 5 and 6, Figures 1 to 4
The same reference numerals as in the figures indicate the same components.

The present invention provides a bundling culm discharging device which has a discharging belt at the rear of the bundling device that guides and discharges the inherited bound culm, and at the starting end of the discharging belt, the discharging of the bound culm from the bundling device is performed. The culm is pushed out of the discharge path of the discharge belt to engage and carry out the binding culm, and as a result of this carrying out, the culm protrudes toward the discharge path and covers the culm between the binding device and the starting end of the discharge belt. Since the regulating body that prevents engagement and conveyance is provided, when the bundled culm passes through the regulating body, the bundled culm pushes this regulating body,
Since it engages with the rotation zone of the discharge belt while being retracted, discharge and conveyance can be carried out smoothly, and
After passing through, the regulating body protrudes into the discharge path and covers the gap between the binding device and the starting end of the discharge belt, as well as the starting end of the discharge belt. It can be widely interposed between the culm and the culm. Therefore, the bundled culm in the discharge path and the culm on the binding device side can be disentangled, and the culm can be effectively prevented from being taken out. Furthermore, the ejection posture of the bundled culms in the discharge path is not disturbed by the entanglement of the culms, making it easier to discharge the bundled culms in a stable state.

It should be noted that this invention is not limited to the above-mentioned embodiments, and can be implemented in modes other than the above-mentioned embodiments.
