A clutch mechanism is provided on the discharge port side of the collecting section that can be freely switched between a closed state and a state in which a plurality of stem culm bundle groups are forcibly discharged to the outside. A reaping bundle is provided with a stock discharging rod that can be elastically displaced within a certain range on one side, and the clutch mechanism is automatically and reversibly engaged and operated based on the elastic displacement of the stock discharging rod above a certain level. Regarding machines.

This type of reaping and tying machine is capable of forcibly discharging a plurality of stem culm bundle groups collected in the collecting section to the outside by having one discharge arm that is originally equipped to the tying device. It is necessary to separately provide, beside the collecting section, a dedicated discharging device for discharging the plurality of stem culm bundle groups collected in the collecting section to the outside, and a drive mechanism for circulating the same within the collecting section. In addition, the structure for detecting that a predetermined amount of stem culm bundles have been collected in the collecting section can be created by effectively utilizing the stock discharging rod. It has the advantage of being simple and economical to construct.

The present invention further improves the reaping and tying machine that has such advantages, and makes it possible to release the stem culm bundle into the field as a single unit depending on the reaping work conditions. The purpose is to avoid inconveniences, that is, disturbances in the ejection position due to wobbling of the stock dispensing rod.

That is, the reaping and tying machine according to the present invention is provided with a mechanism for fixing and holding the stock removal rod at a position where the clutch mechanism enters and operates, and this fixing mechanism is attached to the rod of the stock removal rod. A U-shaped fixing member that fits into the body part from above, and this fixing member is provided at its tip, and the fixing member swings around the horizontal axis in order to switch between an engaged position and an upwardly retracted position. Its structural feature is that it is composed of a swinging arm that is freely pivoted.

According to the present invention having the above characteristics, the following effects can be obtained. That is, by appropriately switching the above-mentioned fixing mechanism to a fixed release state or a fixed state according to field conditions, reaping conditions, etc., a state in which the collected stem culms in the collection section are forcibly discharged to the outside and a state in which the collected stem culms in the bundling space are It is possible to create two types of discharge forms, one in which the stem culm bundle is forcibly discharged as a single bundle to the outside through the collecting section, and the reaping and tying machine can be made more versatile. Moreover, when releasing the collected stem culm bundle group, the entire collected stem culm bundle group can be moved outward by the elastic displacement of the stock discharging rod, and the collected stem culm bundle group can be reliably released in a well-aligned state. At the same time, when discharging a single unit, the stock discharging rod can be reliably fixed and held in a predetermined position, so disturbances in the discharging posture caused by the wobbling of the stock discharging rod can be avoided, and a good flow can be achieved. We were able to perform a single release effect. In particular, since the above-mentioned fixing mechanism is composed of a U-shaped fixing member that fits into the rod body of the stock disbursing rod from above, and a swinging arm that has this fixing member at its tip, the above-mentioned release mode is There is an advantage that switching can be performed with one touch, and the release form can be easily switched.
