Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear part of a threshing device, which is equipped with a stock aligning device for aligning the stock ends of threshing-discharging straws carried in a sideways posture so as to be slidable in the left-right direction. An exhaust straw bundling machine to bind the exhaust straws of
Behind this waste straw bundling machine, there is a combine straw discharge bundling machine that is provided with a bundle gathering device that abuts the waste straw bunch bundle discharged from the waste straw bale binding machine and drops the waste straw bundle to the side away from the uncut area. Regarding the device.

[0002]

2. Description of the Related Art Generally, a combine straw discharging bundle binding device is provided with a stock aligning device for aligning the ends of the waste straws when supplying the threshing discharging straws to the binding machine, and the waste discharged to the field during the cutting operation. In order to prevent the bundle of straws from being stepped on by the combine traveling device, a bundle puller for dropping the discharged bundle of straws discharged from the binding machine to the side away from the uncut land is provided. The stock aligning device is used by acting on the stock end face of the discharged straw, and the bundle pulling tool is used by being brought into contact with the stock base portion of the discharged straw bundle. For this reason, when the culm length of the threshing discharge straw changes, it is of course necessary to adjust the stock aligning device, but also adjust the attachment position of the bundling tool according to the culm length of the discharge straw. Therefore, conventionally, the bundling tool in such a bundling device is attached to a fixed side member such as a binding machine or a machine frame for fixing the binding machine so as to be adjustable in the left-right direction.

[0003]

In the conventional structure as described above, the stock aligning device and the bundling tool must be separately adjusted to the left and right in accordance with the change in the culm length of the discharge straw, and this adjustment work is required. There was a time-consuming problem. An object of the present invention is to make it possible to easily adjust the lateral position of the bundling tool in accordance with the change in the culm length of the discharge straw so that the bundling tool always works in an appropriate state.

[0004]

A feature of the first aspect of the present invention is that the bundling tool is attached to the stock aligning device so that the bundling tool slides left and right integrally with the stock aligning device.

A feature of the second aspect of the present invention resides in that the bundling tool is attached to the stock aligning device so that the left and right positions can be adjusted.

[0006]

According to the characteristic construction of the first aspect of the invention, the bundle gathering tool also slides integrally left and right in accordance with the left-right adjustment of the stock gathering device, so that the positional relationship between the stock gathering device and the bundle gathering device can be set in an appropriate state in advance. If the initial setting is performed, thereafter, the bundle gathering tool can be brought into contact with the fixed position from the stock end of the bundle of straws only by adjusting the stock aligning device, and an appropriate state can always be maintained. Also, because the appropriate action position of the bundle puller changes depending on the hardness or weight of the drainage straw, depending on the culm direction of the drainage straw, the bundle puller should be attached to the stock end of the bundle as described above. Although it may not separate from the uncut land only by acting it on a certain position from the above, according to the characteristic configuration of the second invention, the left and right positions of the stock alignment device are kept in line with the culm length of the drainage straw, Only the pulling tool can be adjusted to the operating position corresponding to the conditions such as the hardness and weight of the discharge straw.

[0007]

As described above, the left-right adjustment of the bundling device can be automatically performed by simply moving the stock aligning device to the left or right according to the culm length of the discharged straw, and the hardness or the weight of the discharged straw can be adjusted. Also, the proper operation state of the bundling tool can be maintained.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show the rear part of the combine, and show a threshing device 1, a waste straw transporting device 2 for transporting the threshing-treated waste straws in a sideways posture, and after collecting a certain amount of the transport waste straws. It is provided with a discharge straw bundling device A for bundling.

The discharge straw bundling device A is provided with a discharge straw scraping-in packer 3a, a needle 3b and the like on the upper side, and
An exhaust straw bundling machine 3 including a building 3c, a holder 3d, and a discharging arm 3e for discharging the bundled discharged straw bunch a to the rear, and an exhaust straw supplied to the focusing space S of the exhaust straw bundling machine 3. From the stock aligning device 4 for striking the stock ends of the stock, and the bundle gathering tool 5 that comes into contact with the discharged straw bundle a discharged by the discharge arm 3e and drops the discharged straw bundle a toward the side away from the uncut land. It is configured.

As shown in FIGS. 4 and 5, the stock arranging device 4 has a gear case 7 in which a bevel gear mechanism 7a is mounted on a drive shaft 6 of a discharge straw scraping packer 3a which is constantly driven.
Is slidably mounted, an arm member 8 is extended forward from the gear case 7, and a stock aligning plate 4a is swingably mounted around a vertical axis Y1 at the front end of the arm member 8. A crank arm 7b that is rotationally driven by the bevel gear mechanism 7a is linked to an elongated hole 4b formed in the middle of the stock alignment plate 4a.
Rotation, the stock aligning plate 4a is oscillated to the left and right around the vertical axis Y1 to strike and align the stock ends of the discharge straws. Further, a female screw member 8a is attached to the arm member 8 extending from the gear case 7, and a screw shaft 9 screwed to the female screw member 8a is provided in parallel with the packer drive shaft 6. Screw shaft 9 to electric motor 10
The stock aligning device 4 is mounted so that it can be slid to the left or right according to the culm length of the discharged straw by rotating the stock aligning device 4 in the forward and reverse directions.

As shown in FIG. 6, the bundle pulling tool 5 is ejected by abutting the action portion 5a of the bundle straw bundle a, which is discharged backward by the discharge arm 3e of the binding machine 3, with the action portion 5a thereof. By rotating the straw bundle and swinging around the stock side on the heavy side, the discharged straw bundle is released from the uncut land and released.
As shown in FIGS. 1 to 3, it is formed of a round pipe bent in an L-shape in a side view, and is fixed to a gear case 7 of the stock aligning device 4 via a bolt 11. The bolt 11 is configured to be rotatable left and right around the axis Y2. As a result, the stock aligning device 4 and the bundle pulling tool 5 can be integrally slid to the left and right, and the action part 5a of the pulling tool 5 can be moved with respect to the stock aligning device 4 by the rotation operation around the vertical axis Y2. The left and right positions of can be adjusted.

It should be noted that although reference numerals are given in the claims for convenience of comparison with the drawings, the present invention is not limited to the configurations of the accompanying drawings by the entry.
