[0001]

The present invention comprises a bundling device for bundling a threshing and discharging straw in a sideways posture and discharging the bundling and discharging straw to the rear of the fuselage. The present invention relates to a threshing and discharging straw processing unit structure of a combine including a stock end aligning member that performs a tapping and aligning operation and a drive mechanism that reciprocally drives the stock end aligning member in the culm direction of the collecting and threshing and discharging straw.

[0002]

2. Description of the Related Art Conventionally, as shown in, for example, Japanese Utility Model Application Laid-Open No. 1-146830, a threshing waste straw is bound by a binding device, and the binding waste straw discharged by the binding device to the rear of the machine is transported by a waste straw transporter. It is constructed so that it can be pinched and conveyed to the side of the traveling machine by the chain and dropped and released, and the tying and discharging straw to be released is discharged to the position immediately behind the tying device, the field location closer to the mown land side Was able to work while falling.

[0003]

Conventionally, the use of a transfer device exclusively for the lateral transfer of a bundled straw is disadvantageous in terms of structure. In addition, the waste straw transport device becomes relatively large, which makes it difficult to operate the machine due to the waste straw transport device, or requires cumbersome labor to store the waste straw transport device so that it does not protrude significantly during non-working travel. I was
An object of the present invention is to make it possible to work while releasing and releasing the united waste straw as much as possible to the cut ground side, and to obtain an advantageous state in terms of structure and size.

[0004]

In order to achieve the object, in the structure of the combine threshing and discharging straw processing section according to the present invention, the drive mechanism is the one described at the beginning, and the binding device is the binding and discharging straw. A mechanism that is driven at a drive timing in which the stock end aligning member is positioned at the tapping aligning operation position when performing the discharging operation, and the stock end aligning member provides a tapping aligning action to the stock side end of the collecting threshing straw. A feed surface portion that moves to the tip end side of the release and bundling straw from the bundling device at a position on the rear side of the body from the bundling device and moves the release and bundling straw into the spike side; It is characterized by being prepared for. The operation and effect are as follows.

[0005]

[Function] By the tapping action of the collecting and threshing straw from the bundling device against the base side end of the straw, the collecting and threshing straw have the same stock position and the bundling and discharging straw from the bundling device. At the time of release, the stock end alignment member is located at the knocking action position, so that the movement of the bundling discharge straw to the base of the stock is prevented, and the feed surface portion formed integrally with the stock end alignment member is released. By contact with the end of the united straw,
The released and bound straw is forcibly moved to the tip side, and as a result, the released and bound straw falls to a field closer to the already cut side than the position where it was bound by the binding device.

[0006]

Therefore, not only is there no need for a dedicated device such as the conventional waste straw transporting device, but also the feed surface portion is integrally provided with the stock end aligning member, and the number of components is not increased. Despite the configuration, the stock alignment function by the stock end alignment member is effectively exerted, and at the same time, the released and bound straw is released to the mown side of the field, so that the bundled straw that has been released to the field scene is discharged to the next field. The structure of the threshing and discharging stirrer processing unit of the combine without being trampled on the traveling device during the mowing work process was obtained with a compact configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 3, a bundling device 2 for threshing and discharging straw is attached to the rear of a threshing device 1 and threshing and discharging straw carried out from a handling room (not shown) of the threshing device 1. The waste straw transporting device 3 that pinches and transports the stock side and the waste straw transporting device 4 that latches and transports the tip side, transports and supplies the binding device 2 while moving to the tip side in a sideways posture. Thus, the threshing and discharging straw processing unit of the combine is configured so that the threshing and discharging straws are bound in a long straw state and discharged to the rear of the machine in association with the threshing processing of the harvested grain culm. The binding device 2 is configured as shown in FIGS. That is, a binding space S is formed by the waste straw receiving plate 7 between the upper frame 5 and the lower frame 6 forming the binding device body, and the threshing waste straws from the waste straw transport devices 3 and 4 are driven and rocked. The scraper packer 5 supplies the paper to the binding space S and collects it in a sideways posture. When the collection amount of the threshing waste straw reaches the set amount, the discharge straw scraping supply pressure acting on the sensing door 9 closing the discharge straw outlet of the binding space S reaches the set pressure, and the binding clutch (not shown) operates. Upon entering, the needle 10 and the like are operated to bind the collecting and discharging straw. As shown in FIG. 2, upon completion of the binding of the straw, the discharge arm 11 is driven to discharge the bound straw from the binding space S to the rear of the machine in a sideways posture.

[0010] A stock end aligning member 12 made of sheet metal for threshing and discharging straw collected in the binding space S is connected to a main body of a transmission case 15 attached to the upper frame 5 and a support arm portion 15 a via a support frame 13 and an operation link 14. And is supported by the transmission case 15. The driving body 1 is provided so that the transmission case 15 is rotatably driven.
6 and the operation link 14, the stock end alignment member 12
The drive mechanism 17 is configured to perform the binding processing while improving the alignment of the stitches of the binding straw. That is, the support arm portion 15a supports the support frame 13 so as to rotate around the axis P in the vertical direction of the body, and operates the support frame 13 so as to reciprocate around the axis P. 1 and 3 where the stock end aligning member 12 is separated from the transmission case 15 toward the collecting and discharging stirrer by a stroke end position indicated by a solid line in FIG. 1 and FIG. Reciprocates between the stroke end position B indicated by the imaginary line in FIGS. 1 and 3 in the direction of the culm of the collected straw, performs the tapping action portion 12a, and the stock end of the collected straw. It works by tapping. The driving body 16 is rotationally driven to push and pull the operation link 14 so that the support frame 1 is moved.

Is provided so as to act on the bundling discharge straw discharged by the discharge arm 11. The driving mechanism 16 drives the stock end aligning member 12 at a predetermined timing by interlocking the driving body 16 by a gear mechanism 18 so that power is transmitted to a binding device driving shaft 19. The stock end aligning member 12 is also used as a shifting member, and is configured to be able to work while dropping the bundling straw as close as possible to a field location as close as possible to the cut ground side from the position where the bundling straw is bound by the bundling device. is there. That is, when the bundling device 2 performs the bundling discharge stirrer releasing operation as shown in FIGS. 1 and 2, that is, when the discharging arm 11 discharges the bundling discharge stirrer, the stock end aligning member 12 is hit. The reciprocating drive of the stock end aligning member 12 is performed at the drive timing located at the aligning action position A. As a result, when the binding and discharging stirrer pops out of the binding space S, FIG.
As shown in (a), the tapping and aligning action portion 12a of the stock end aligning member 12 taps on the binding and discharging straw, and the binding and discharging straw jumps out while moving to the tip side. When the stock end aligning member 12 is located at the tapping aligning action position A, as shown in FIG. When the discharged straw comes into contact with the feed surface portion 12b, the binding discharge straw is moved forward as shown in FIG. It is configured to move to the side. In short, the binding space S
