Description

[Detailed Description of the Invention] Industrial application The present invention relates to a combine for bundling discharged culms and discharging them in a standing posture. The present invention relates to an culvert bundle discharging device that can be kept and smoothly dropped.

Conventional technology The combine harvester that binds the culm after threshing at the threshing unit at the tying unit and discharges the culm bundle to one side of the machine to land in a standing posture is No. Shokai Sho 60-133746. The one described in the publication is known, and the culm bundle mechanism in this combine is composed of a conveyor chain and a conveyor guide body facing the conveyor chain, and imparts resistance in the conveyor direction to the culm bundle. It is designed to be transported while rotating it. Also,
A device for providing a drop guide plate for the discharged culm bundle at the end of the conveying chain of the discharged culm bundle conveying mechanism is described in Japanese Utility Model Laid-Open No. 58-113334.

Problem to be solved by the invention By the way, when the culm bundle conveying mechanism conveys while rotating the culm bundle, the culm or the binding string, which is frayed from the culm bundle at the end of the conveyor, causes winding around the sprocket of the conveyor chain. It often happens that the edge of the fall guide plate is also caught, and the culm bundle does not fall smoothly and is stagnant, or the culm bundle that should be landed in a standing posture falls. There is.

In view of the above-mentioned problems, the present invention, in view of the above-mentioned problems, causes the waste culm bundle conveyed while being rotated by the discharge culm bundle transport mechanism to be wound around the sprocket of the transport chain at the transport end portion or to be hooked on the peripheral portion thereof. It is an object of the present invention to provide a culvert bundle discharging device in a combine that can always smoothly drop without causing a risk of landing and can land the culm bundle in an appropriate standing posture.

Means for Solving Problems The present invention has the following technical means for achieving the object. That is, the culm bundle discharging device in the combine according to the present invention is a combine chain for discharging the culms after threshing and discharging them in a standing posture, in the discharging direction of the culm bundle from the binding part of the culm and the conveying chain and the same. An culm bundle conveying mechanism is provided, which is composed of opposed conveying guides, and conveys the culm bundle in a vertical posture while rotating by giving resistance in the conveying direction, and at the conveying end portion of the culm bundle conveying mechanism. In addition, it is necessary to cover the terminal turning portion of the transport chain from directly above and to provide a slide plate in which the passage side edge of the culm bundle is bent and extended upward so that the culm bundle is vertically dropped along the slide plate. It is a feature.

Action The culms after threshing in the threshing unit are bound by the binding unit, and the culm bundles are conveyed by being sandwiched between the conveying chain of the culm bundle conveying mechanism and the conveyance guide body, and during this conveyance, the culm bundles are It rotates in response to resistance in the transport direction, and the lower part of the binding part opens in a circular shape, falls from the transport end part in a vertical posture and lands in a standing posture. By the way, at the transport end portion of the culm bundle transport mechanism, a sliding plate that vertically drops the culm bundle on the transport chain side covers the terminal turning portion of the transport chain from immediately above,
In addition, since the edge of the sliding plate on the passage side of the culm bundle is bent and extended upward, the culm bundle does not wrap around the sprockets of the transport chain. , Guided by the sliding plate to fall smoothly.

Embodiment An embodiment of the present invention will be described with reference to the drawings.

An example of a self-thinning combine is shown in the drawing, 1 is a threshing section, 2 is a binding section, 3 is a culm bundle transporting mechanism, and in the threshing section 1, culm after threshing is a binding section 2. The bundled and bundled discharged culm bundle is conveyed to one side of the machine body by the discharged culm bundle conveying mechanism 3 and discharged outside the machine body.

The culm bundle conveying mechanism 3 is composed of a conveying chain 4 extending from the binding portion 2 in the discharging direction of the culm bundle and a conveying guide body 5 facing the conveying chain 4, and the conveying guide body 5 is attached to the conveying chain 4. On the other hand, the guide rail 6 is supported so that it can be moved back and forth. The guide rail 6 has a culm bundle receiving guide 7 at the end on the binding portion 2 side and a culm bundle drop guide 8 on the discharge side end. The support body 9 of the guide rail 6 and the chain case 10 of the transport chain 4 are attached to the machine body by the support arm 11. As shown in FIG. 4, a slide plate 12 is attached to the chain case 10 to cover the end turning portion, that is, the sprocket portion, from directly above the transfer end portion of the transfer chain 4. Reference numeral 12 denotes a sliding side surface formed by bending upward an edge portion on the passage side of the culm bundle, that is, an edge portion located on the rear surface side of the transport chain 4.
The culm bundle receiving guide 7 guides the culm bundle supplied from the bundling portion 2 in an inclined manner in the conveying direction while changing it to a vertical posture, and the culm drop guide 8 together with the sliding plate 12 drops the culm. This is for keeping the culm in a vertical position. The guide rail 6 is provided with a plurality of protrusions 13 for imparting resistance in the transport direction to the transported culm bundle. Reference numeral 14 is a sweeper of the binding unit 2.

In the one configured as described above, the culms after threshing in the threshing unit 1 are bound by the binding unit 2 and conveyed to the discharge position by the culm bundle conveying mechanism 3, but are conveyed by the culm bundle conveying mechanism 3. The culm bundle that is sandwiched and conveyed between the chain 4 and the guide rails 6 of the conveyance guide body 5 is rotated by the projection 13 of the guide rails 6 that receives the resistance in the conveying direction, so that the lower part from the binding portion has a circular shape. It will be in an expanded state. Then, the culm bundle reaching the conveyance end of the culm bundle conveying mechanism 3 is guided by the sliding plate 12 and the culm drop guide 8 and drops while maintaining a vertical posture, and lands in a standing posture. The culm bundle that falls vertically like this
The lower part has a circular expansion shape, so the standing posture after landing is stable. Further, a slide plate 12 is provided at the end of conveyance of the culm bundle conveying mechanism 3 so as to cover the terminal turning portion of the conveyance chain 4 from immediately above. Further, the slide plate 12 is a passage side edge of the culm bundle. Since the part is bent and extended upward,
Although the frayed culms and the binding cords of the culm bundle may not be wound around the sprocket, the culm bundle may always be smoothly dropped without being caught by the edge of the sliding plate 12.

Advantages of the Invention In short, the present invention, in a combine for binding and discharging culm after threshing in a standing posture, in the direction of discharging the culm bundle from the stacking part of the culm, the conveying chain and the conveying guide facing it. And a drainage bunching mechanism configured to convey the culm bundle in a vertical posture while applying a resistance in the transporting direction to the culm bundle and rotating the culm bundle in the vertical direction. While covering the terminal turning portion from directly above, providing a sliding plate in which the passage side edge of the culm bundle is bent and extended upward,
Since the culm bundle is dropped vertically along the sliding plate,
The culm bundle transported while being rotated by the culm bundle transport mechanism does not have the risk of being caught around the sprocket of the transport chain at the transport end and caught on the edge of the sliding plate, and can be smoothly dropped at all times. This has the effect of landing the culm in an appropriate standing posture.
