DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stocking device for aligning stock ends of threshing waste straws carried out in a sideways posture at the rear of a threshing device, slidably movable in the left-right direction, and after stocking. A waste straw binding machine that binds the waste straws
At the rear of the waste straw bundling machine, a combine straw bundling device provided with a bundle pulling device that comes into contact with the waste straw bundle discharged from the waste straw bundling machine and drops the waste straw bundle away from the uncut land. Related to the device.

[0002]

2. Description of the Related Art In general, a combine straw discharging straw binding device is provided with a stocking device for aligning the ends of the throwing straw when supplying threshing waste straw to a binding machine, and a waste straw discharged to a field during a mowing operation. In order to prevent the straw bundle from being stepped on by the traveling device of the combine, there is provided a bundle pulling device for dropping the waste straw bundle discharged from the binding machine away from the uncut land. The stock arranging device is used by acting on the stock end face of the waste straw, and the bundle puller is used by being brought into contact with the base of the waste straw bundle. For this reason, when the culm length of the threshing straw is changed, it is necessary to adjust not only the stocking device but also the attachment position of the bundle puller in accordance with the culm length of the straw. Therefore, in the related art, a binding device in such a binding device has been mounted on a fixed side member such as a binding device or a machine frame for fixing the binding device so as to be adjustable left and right.

[0003]

In such a conventional structure, it is necessary to separately adjust the left and right of the stock arranging device and the bundling tool according to the change in the culm length of the straw. There was a time-consuming problem. An object of the present invention is to make it possible to easily adjust the left / right position of the bundle closing tool according to the change in the culm length of the straw, and to always operate the bundle closing tool in an appropriate state.

[0004]

According to a first feature of the present invention , a tilting stock plate is provided at the rear of the threshing device so as to fall down.
A stock alignment that strikes the end of the threshing straw that was carried out in a posture
The device can be slidably mounted to the left and right
In addition, we set up a waste straw binding machine that binds
In a combine threshing apparatus, the waste straw bundling machine
From the working area of the stock plate
Abutting against the sheaf and dropping the waste straw bunch away from the uncut land.
With the bundling tool to be provided behind the
Then, slide the bundle closet together with the stock
It is attached to the fixed part of the stock arranging device so as to be mounted .

[0005] The characteristic structure of the second invention is described in the first invention.
In the above, the bundle pulling tool with respect to the stock alignment device,
It is located at the point where it can be adjusted left and right.

[0006]

According to the characteristic structure of the first aspect of the present invention, the bunching tool slides right and left integrally in accordance with the left and right adjustment of the stock arranging device. If the initial setting is made, thereafter, only by adjusting the stock aligning device, the bundle pulling tool can be brought into contact with a fixed position from the stock end of the waste straw bundle, and an appropriate state can always be maintained. Also, due to differences in the hardness or weight of the straw, the appropriate working position of the bundle shifter changes in the direction of the culm of the straw. However, according to the characteristic configuration of the second invention, the left and right positions of the stocking device are adjusted to the culm length of the straw, Only the moving tool can be adjusted to an operating position corresponding to conditions such as hardness and weight of the waste straw.

[0007]

Therefore, by simply moving the stocking device to the left and right according to the culm length of the straw, it is possible to adjust the right and left of the bundle puller naturally, and to deal with changes in the hardness or weight of the straw. It is also possible to maintain an appropriate operation state of the bundle moving device.

[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, a threshing device 1, a waste straw transporting device 2 for transporting the thresh-treated waste straw in a sideways posture, and after collecting a certain amount of the transported straw. It is provided with a waste straw binding device A for binding.

The waste straw bundling apparatus A is provided with a waste straw scraping-in packer 3a, a needle 3b, and the like above,
An exhaust straw bundling machine 3 provided with a building 3c, a holder 3d, and a discharge arm 3e for releasing the bundled exhaust straw bundle a to the rear, and the exhaust straw supplied to the focusing space S of the exhaust straw bundling machine 3. A stock aligning device 4 for hitting and aligning the ends of the stock, and a bundle pulling tool 5 for contacting the waste straw bundle a discharged by the discharge arm 3e and dropping the waste straw bundle a away from the uncut ground. It is configured.

As shown in FIGS. 4 and 5, the stock arranging device 4 includes a gear case 7 in which a bevel gear mechanism 7a is mounted on a drive shaft 6 of a constantly driven scraper scraping packer 3a.
Is slidably mounted, an arm member 8 is extended forward from the gear case 7, and a stock alignment plate 4a is attached to the front end of the arm member 8 so as to be swingable about the vertical axis Y1. A crank arm 7b, which is driven to rotate by the bevel gear mechanism 7a, is linked to an elongated hole 4b formed in an intermediate portion of the stock arrangement plate 4a.
With the rotation of, the stock aligning plate 4a is driven to swing left and right around the vertical axis Y1, so that the stock ends of the waste straw are beaten and aligned. 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 laid in parallel with the packer driving shaft 6. Screw shaft 9 to electric motor 10
The stock alignment device 4 is mounted so that it can be slid right and left according to the culm length of the straw to be removed by rotating the stock device 4 forward and backward.

As shown in FIG. 6, the bundle puller 5 has its action portion 5a in contact with the base portion of the waste straw bundle a which is discharged backward by the discharge arm 3e of the binding machine 3, and discharges the bundle. By rotating the straw bundle and swinging the heap base, the discharged straw bundle is separated from the uncut land and dropped and released,
As shown in FIG. 1 to FIG. 3, it is constituted by a round pipe bent in an L-shape when viewed from the side, and is fixed to a gear case 7 of the stock arranging device 4 via a bolt 11. The bolt 11 is configured to be able to turn left and right around the axis Y2. Thus, the stock aligning device 4 and the bundle pulling tool 5 can be integrally slid left and right, and the action part 5a of the pulling tool 5 with respect to the stock aligning device 4 by a rotation operation about the vertical axis Y2. You can adjust the left and right position.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the accompanying drawings.
