Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a structure in which one end of the bundling space is pivotally connected to the free end of the reciprocating swing link, and the intermediate part thereof is pivotally connected to the eccentric part of the drive rotating body. do,
A stem culm bundle discharge port side from the binding space of a bundling device equipped with a discharge arm capable of forcibly discharging the stem culm bundle in the bundling space to the outside by a circulation movement accompanying the driving rotation of the driving rotary body. The present invention relates to a reaping and tying machine having a collection section that can collect and hold a plurality of bundles of stems and culms. This type of reaping and tying machine collects a plurality of stem culm bundles discharged from the binding space of the tying device in a collecting section, and then releases the stem culm bundles in this collecting section all at once into the field. As a result, although it is possible to bundle the stalks into small bundles, which are the easiest to handle, during post-processing such as sun drying and threshing, multiple bundles of stems and culms are collected in one place and released into the field. Therefore, the subsequent collection work can be carried out efficiently and easily.However, conventionally, a dedicated discharge tool for discharging the plurality of stem culm bundles collected in the collecting section is provided separately from the discharging arm of the binding device. It was set up. Therefore, a discharging device dedicated to the collected stem culm bundle and a drive mechanism for circulating the discharging device within the collecting section are required, and the entire discharging mechanism becomes structurally complex and large, which is disadvantageous in terms of production and economy. Ta. The present invention makes it possible to construct a mechanism for performing the two types of release functions as described above in a simple and compact structure by utilizing one release arm that is originally equipped to the binding device. The first purpose is to make a herring, and the second purpose is to ensure the outward forced release of the plurality of stem and culm bundle groups collected in the collecting section. That is, in the reaping and binding machine according to the first invention described above, the arm that holds the swinging fulcrum shaft of the reciprocating swinging link is configured to be rotatable around the rotational axis of the drive rotary body, and A mechanism for biasing and holding this arm at a fixed position on its rotational path, and a mechanism for rotating the arm integrally with the driving rotor against the biasing force, allow the discharge arm to collect a plurality of particles in the collecting section. The present invention is characterized by being equipped with a clutch mechanism that can be switched to a state in which the stem and culm bundle group is forcibly released outward.
Based on the collection of a predetermined amount of stem culm bundles in the collecting section, the clutch mechanism is automatically or manually engaged and actuated to release one release arm originally equipped to the bundling device. The plurality of stem culm groups collected in the collecting section can be forcibly discharged to the outside, and the clutch mechanism is disconnected and activated, and the swinging fulcrum arm of the reciprocating swinging link is moved. By biasing and holding the stem at a fixed position along the rotation path, a normal discharge form can be realized in which the stem culm bundle in the bundling space is forcibly discharged toward the collecting section. Therefore, with a simple modification to the fulcrum arm of the reciprocating swing link, the above-mentioned two types of release states can be realized, so that the plurality of stems collected in the collecting section can be There is no need to separately provide a dedicated release tool for forcibly releasing the culms to the outside and a drive mechanism for circulating it within the collection section, and the overall structure of the release mechanism is simplified and compact, resulting in economical savings. We have now been able to achieve this goal. Further, in the reaping and binding machine according to the second aspect of the present invention, in the above-described one, the arm that holds the swing fulcrum shaft of the reciprocating swing link is configured to be rotatable around the rotation axis of the drive rotary body, and A mechanism for biasing and holding this arm at a fixed position on its rotational path, and a mechanism for rotating the arm integrally with the driving rotor against the biasing force, allow the discharge arm to collect a plurality of particles in the collecting section. a clutch mechanism that can be switched to a state of forcibly discharging the stem culm bundle group outward, and the clutch mechanism is used to temporarily stop the discharging arm at the collecting stem culm group discharging terminal position, and then The present invention is characterized in that the cutting operation is performed so that the stem culm bundle in the bundling space returns to its starting position before the forced release operation is performed toward the collecting section. for example,
such as when the discharging arm is immediately returned from the collecting culm discharging end to its starting position;
A part of the collection stem culm bundle group that is forcibly discharged by this discharge arm does not fall down into the collection section due to reaction.
It has now become possible to ensure the forced release effect of this group of collected stem and culm bundles. Embodiments of the present invention will be described below based on the drawings.
