The needle 10 and the knotting mechanism 13 are configured to bind the reaped stem culms collected in the binding space 6 by synchronized driving based on the detection of a focusing pressure of a certain level or more by the door 15. One end of the ejection arm 14 is connected to a fulcrum arm 16
It is pivotally connected to the free end of a reciprocating swinging arm 18 which is pivotally mounted via a swinging fulcrum shaft 17, and its intermediate part is pivotally connected to an eccentric part of a timing gear 19 which is a component of the connecting mechanism 13. The bundles of stems and culms in the bundle space 6 are forcibly discharged by the circulation movement caused by the intermittent rotation of the timing gear 19. The support arm 16 that supports the swing fulcrum shaft 17 is configured to be rotatable around the axis of the intermittent drive shaft 20 of the timing gear 19, and the support arm 16 that supports the swing fulcrum shaft 17 is configured to be rotatable around the axis of the intermittent drive shaft 20 of the timing gear 19. A spring 21A and a stopper 21B are provided which constitute a mechanism 21 for biasing and holding the arm 16 in a fixed position on its rotational path. Also, the fulcrum arm 16 is moved against the timing gear 19 against the biasing force of the spring 21A.
By rotating integrally with the release arm 1
A clutch mechanism 22 is provided which can be switched to a state in which a plurality of stem culm bundle groups collected in the collecting section 7 are forcibly discharged laterally outwardly using a clutch mechanism 22, and the stock discharging rod 8 is connected to the stem culm bundle group. It is configured to be able to swing laterally and outwardly within a certain range against the elastic force of the spring 23 as it comes into contact with the stem culm bundle. The clutch mechanism 22 is automatically and reversibly engaged and actuated based on a rocking displacement of a certain value or more when the clutch mechanism 22 is collected. The clutch mechanism 22 is constructed as follows. That is, a roller 26 is attached to the pivot shaft 24 of the discharge arm 14 and the swing arm 18, and is movable in and out of the timing gear 19, and is biased to move in the direction of separation via a spring 25.
