Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is intended to convey a bundle of bundles of discharged straw while sandwiching the bundle of discharged straws to the discharge port side of a bundle of bundles of discharged straw attached to a threshing unit.
The present invention relates to a combine straw discharge device for discharging a bundle of bundles of waste after transporting the bundle of straws to a desired position by providing a sandwiching and transporting device including a sandwiching and transporting chain and a sandwiching rail arranged in parallel to each other. .

[Conventional technology]

In the conventional straw discharging device, the holding rail is
Extending straight ahead of the holding and conveying chain,
Discharging the discharged straw bundle from the discharge straw binding device to the extended portion of the sandwiching rail, and scraping the discharged straw bundle backward at the start end of the sandwiching transfer chain while holding the discharged straw bundle at that portion. I was trying.

[Problems to be solved by the invention]

By the way, the bundle of discharged straws discharged from the discharge straw binding device to the extended portion of the gripping rail does not have a force to be forcibly conveyed to the rear, and is simply discharged by the gripping rail. Since the posture is maintained only as it is, for example, when the amount of the discharged straw bundle discharged from the discharged straw binding device is temporarily large, the discharged straw bundle is held in the sandwiched conveyance chain. There was a problem that it could not be completely scratched.

Therefore, it is considered that another guide is provided on the extending portion of the holding rail and the posture is corrected and held so that the bundle of discharged straws can be easily scraped backward by the guide. However, it was difficult to say that it was sufficient to solve the above problems.

The present invention was created with attention paid to such circumstances.

[Means for solving problems]

A characteristic configuration of the present invention is that, on the discharge port side of a waste straw bundling device attached to a threshing section, a sandwich transport chain for sandwiching and transporting the bundle of waste straw bundles and a sandwich rail arranged opposite to the chain. In a combined waste discharge device for discharging a bundle of waste straws to a desired position by the sandwiching and transporting device, the sandwiching and transporting device includes a sandwiching rail and a sandwiching rail. The upper chain structure is located on the upper side, and at the start end of the pinching and conveying device, the chain path of the pinching and conveying chain is bent obliquely upward and away from the pinching rail, and by the bent chain route and the front end of the pinching rail, It is characterized in that a space for receiving the discharged straw bundle is formed in a shape that expands toward the discharged straw binding device side.

[Action]

In such a combine straw discharge device of the present invention, a space for receiving the discharge straw bundle is formed at a portion where the gripping of the discharge straw bundle by the sandwich conveying chain and the sandwiching rail is started, and the space is formed. Since the boundary of one corner is formed by the sandwiching conveyance chain, when the discharged straw bundle from the discharge straw binding device is discharged into the space, the bundle of discharged straws in the space is changed by the sandwiching conveyance chain. Then, it is scraped back to the rear, and is forcibly held between the sandwiching carrier chain and the sandwiching rail.

Since the space for receiving the discharged straw bundle is of the upper chain structure in which the chain is on the sandwiching rail, the discharged straw bundle discharged from the binding device is treated like the lower chain structure with the chain on the lower side. Rather than positively retracting and transporting, some bundles of discharged straw are collected and come into contact with the bent chain path to be retracted and pinched and transported.

In other words, the space for receiving the discharged straw bundles has a buffer effect of temporarily receiving the plurality of discharged straw bundles, and the discharged straw bundles from the binding device can be smoothly transferred to the sandwiching and conveying device without clogging.

[Effect of device]

Therefore, even when the amount of the discharged straw bundle discharged from the discharged straw binding device is temporarily increased, the discharged straw bundle does not become clogged and is smoothly and reliably held between the sandwiching conveyance chain and the sandwiching rail. It is possible to reliably achieve the intended purpose of the discharge straw discharging device that is scraped into the discharge straw bundle to be discharged after being conveyed to a desired position.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1 and FIG. 2, a transport device (3) for transporting the threshing discharge straws from the feed chain (2) toward the rear of the machine is provided at the rear part of the threshing discharge mouth of the threshing part (1). Further, at the rear portion thereof, a waste straw bundling device (4) for bundling the threshing waste straw supplied from the transport device (3) in a horizontal posture.
Has been placed. Then, on the discharge port side of the discharge straw bundling device (4), there is provided a holding and conveying device (5) for holding and conveying the tip end side of the discharge straw bunch bundled in a sideways posture, and the holding and conveying device (5). In step (4), the bundle of discharged straws is conveyed to a desired position and then discharged, thereby forming a combined straw discharge device.

The holding and conveying device (5) includes a drive sprocket (51a).
And a holding conveyance chain (51) which is driven by a driven sprocket (51b), guided by driven sprocket (51c) and swivels to the upper side of the discharge straw bundle passing area, and so as to face the holding conveyance chain (51). It is composed of a sandwiching rail (52) arranged below the discharge straw bundle passage area.

And, the chain path of the holding and conveying chain (51) is arranged by arranging the drive sprocket (51a) in front of the driven sprocket (51b) (in other words, on the side of the discharge straw binding device (4)). , At the start end of the nipping and conveying device (5), the chain path of the nipping and conveying chain (51) is bent obliquely upward to separate from the nipping rail (52), and the bent chain path and the front end of the nipping rail (52) are formed. Thus, a discharge straw bundle receiving space (A) having a shape that expands toward the discharge straw binding device side is formed.

The holding rail is a linear rail which is elastically supported by a pair of coil springs (52b) and (52b) carried by an extension rod (52a) extended from the body side, and the holding rail holds the holding rail. Although it is configured such that the bundle of discharged straws can be elastically held between the rail (52) and the holding and conveying chain (51), the linear rail (52) is sandwiched between the holding and conveying device (5). The weight may be reduced and the cost may be reduced by supporting the piano wire extended from the terminal end portion in an arc shape by an elastic extension rod made of spring steel or the like. In this case, the elastic extension rod is also useful for correcting the discharge posture of the discharged straw bundle immediately after being discharged from the sandwiching and conveying device (5).

With respect to the combined straw discharge device having such a structure,
A space (A) for receiving the bundle of discharged straws is formed at a portion where the gripping of the bundle of discharged straws by the holding and conveying chain (51) and the holding rail (52) is started, and a space (A) for receiving the bundle of discharged straws is formed. Since the boundary is formed by the sandwiching and conveying chain (51), when the discharged straw bundle from the discharged straw binding device (4) is discharged into the space (A), the discharged straw in the space (A) is discharged. The bundle of straws is scraped backward by the holding and conveying chain (51), forcibly holding the holding and conveying chain (51) and the holding rail (5).
2) It will be scratched between and.

It should be noted that the tip of the discharge arm (4a) of the discharge straw binding device (4) intersects with a corner in front of the space (A), and the space (A) is formed by the discharge arm (4a). )
The discharge straw bundle discharged into the inside is provided so as to be conveniently scraped backward by the holding and conveying chain (51) as described above.

[Another embodiment]

In the above-mentioned embodiment, the holding and conveying device merely conveys the discharged straw bundle to the desired position and then discharges the discharged straw bundle as it is, but the conveying device finishes conveying the discharged straw bundle. It is said that the present invention can be applied to a device for three-dimensionally discharging a bundle of discharged straws by placing the bundle of discharged straws in a standing posture in which the root side is positioned downward until the discharge of the bundle of discharged straws is started. There is no end.

It should be noted that reference numerals have been entered in the section of the claims for utility model registration for convenience of comparison with the drawings, but the invention is not limited to the structure of the accompanying drawings by the entry.
