Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is provided with a bundling device for bundling the threshing and discharging straws in a sideways posture and discharging the bundling and discharging straws to the rear of the machine body. The present invention relates to a combine threshing and discharging straw processing unit structure including a aligning member and a drive mechanism for reciprocally driving the stock edge aligning member in the culm direction of the collected threshing and discharging straw.

[0002]

[Prior Art]

 In a combine, conventionally, for example, as disclosed in Japanese Utility Model Laid-Open No. 1-146830, the threshing discharge straws are bound by a binding device, and the binding discharge straws discharged by the binding device toward the rear of the machine are discharged by the discharge straw transport chain from the traveling machine body. It is configured so that it can be nipped and conveyed laterally to one side, and can be dropped and discharged, so that the discharged bundled straws fall to a field location closer to the already cut area than when discharged to a location immediately after the binding device. There was something that I was able to work while doing it.

[0003]

[Problems to be solved by the device]

 Conventionally, since a transfer device dedicated to the lateral transfer of bundled discharge straws is adopted, it is disadvantageous in terms of structure. In addition, the discharge straw conveyor becomes relatively large, which makes it difficult to control the machine due to the discharge straw conveyor, and it is necessary to store the waste straw conveyor so that it does not protrude significantly during non-working traveling. Was there. An object of the present invention is to enable the work to be performed while discharging the bundled discharge straw as close as possible to the cut land side, and to obtain an advantageous state in terms of structure and size. is there.

[0004]

[Means for Solving the Problems]

 In order to achieve the object, in the structure of the combine threshing and discharging straw processing part of the combine according to the present invention, in the one described at the beginning, the drive mechanism causes the stock edge adjustment when the binding device performs the binding and discharging straw discharging operation. A member that is driven at a driving timing when the members are located at the tapping and aligning position, and is a guide surface portion that abuts on the root side end of the discharge binding discharge straw by the binding device to move the discharge binding discharge straw to the tip side. Is provided in the stock edge aligning member. The operation and effect are as follows.

[0005]

[Action]

 When the bundling device discharges and the bundling discharge straw jumps out of the bundling device, the stock edge aligning member is driven to the knocking alignment position, and the tapping aligning portion of the stock edge aligning member knocks on the bond discharging straw. At the same time, the guide surface part abuts against the bundling and discharging straw, and the bundling and discharging straw is displaced due to the tapping action by the tapping and aligning action part and the displacement due to the moving action by the guide surface part. It jumps out while shifting its position, and falls on the field at a position closer to the cut side than the position where it was bound by the binding device.

[0006]

[Effect of the device]

 Since the stock edge aligning member is also used as a gathering member for the bundle discharging straw, it is easy to avoid trampling by the traveling device of the binding discharging straw discharged when the row to be cut ahead of the row currently to be cut is worked. However, the structure is simple and compact without the need for a dedicated device such as a conventional waste straw transfer device, and it is relatively inexpensive, and it does not require a relatively easy operation of the airframe or a switching labor. Etc. became advantageous.

【Example】

 As shown in FIG. 3, a binding device 2 for threshing and discharging straws is attached to the rear part of the threshing device 1, and the threshing and discharging straws carried out from the handling room (not shown) of the threshing device 1 are attached to the stocker side. The discharge straw conveying device 3 that performs a sandwiching conveyance operation and the discharge straw conveying device 4 that locks and conveys to the tip side are configured to be conveyed to the bundling device 2 while being moved to the tip side in a sideways posture. The threshing and discharging straw processing unit of the combine is configured so that the threshing and discharging straw is bound in a long straw state and discharged toward the rear of the fuselage along with the threshing processing of the cut culm. The binding device 2 is configured as shown in FIGS. That is, a binding space S is formed by the discharge straw receiving plate 7 between the upper frame 5 and the lower frame 6 forming the binding device body, and the threshing discharge straws from the discharge straw conveying devices 3 and 4 are driven and swung. The scraping packer 5 supplies the binding space S and collects it in a sideways posture. When the collection amount of the threshing discharge straw reaches the set amount, the discharge straw scraping supply pressure acting on the sensory door 9 closing the discharge straw outlet of the binding space S reaches the set pressure, and the binding clutch (not shown) The needle 10 is actuated to bind the collecting and discharging straws. When the binding of the discharged straws is completed, as shown in FIG. 2, the discharge arm 11 is driven to discharge the bundled discharge straws from the binding space S rearward of the machine body in a sideways posture.

The stock edge aligning member 12 made of sheet metal for the threshing-discharging straws collected in the binding space S is connected via the support frame 13 and the operation link 14 to the main body of the transmission case 15 attached to the upper frame 5 and the support arm portion. It is configured to be supported by the transmission case 15 by being connected to 15a. Then, a drive mechanism 16 for the stock case aligning member 12 is constituted by a drive body 16 that is rotatably driven by the transmission case 15 and the operation link 14, and a binding process is performed while the stock end alignment of the binding discharge straw is improved. It is configured so that it can be done. That is, the support arm portion 15a supports the support frame 13 so as to rotate about an axis P in the vertical direction of the machine body, and the support frame 13 must be operated so as to reciprocally swing about the axis P. Thus, the stock edge aligning member 12 is separated from the transmission case 15 toward the collecting / discharging straw, and the tapping aligning position A and the tapping aligning position A are formed at the stroke end positions shown by the solid lines in FIGS. 1 and 3. Is reciprocated between the stroke end position B shown in phantom in FIG. 1 and FIG. 3 on the opposite side in the direction of the culm of the collecting and discharging straw, and the knocking aligning portion 12a is used to form the end of the collecting and discharging straw at the root side. It strikes and aligns. When the driving body 16 is rotationally driven to push and pull the operation link 14, and the supporting frame 13 is reciprocally rocked, the driving mechanism 17 causes the stock end aligning member 12 to be a collecting and discharging straw. It is reciprocatingly driven so that the taps are aligned.

A guide surface portion 12 b is provided at a position located on the rear side of the machine body with respect to the tapping action portion 12 a of the stock end aligning member 12 so as to be arranged so as to act on the binding discharge straw discharged by the discharge arm 11. is there. The drive mechanism 16 is interlocked with the gear mechanism 18 so that power is transmitted to the binding device drive shaft 19, so that the drive mechanism 17 drives the stock edge aligning member 12 at a predetermined timing. As a result, the stock edge aligning member 12 can also be used as a pulling member, and the work can be performed while dropping the bundling / discharging straw to a field location as close to the cut land as possible from the position at which it is bound by the bundling device. Is configured. That is, the drive mechanism 16 causes the stock edge aligning member 12 to move when the bundling device 2 performs the bundling / discharging straw discharging operation as shown in FIGS. 1 and 2, that is, when the discharging arm 11 discharges the bundling / discharging straw. The stock end aligning member 12 is reciprocally driven by the drive timing located at the tapping action position A. As a result, when the binding discharge straw jumps out of the binding space S, as shown in FIG. The tapping and aligning operation portion 12a of the edge aligning member 12 acts on the binding and discharging straw so that the binding and discharging straw is ejected while moving to the tip side. When the stock end aligning member 12 is located at the tapping aligning position A, the guide surface portion 12b abuts on the stocker side end portion of the binding discharge straw that pops out as shown in FIG. When the bundle discharge straw comes into contact with the guide surface portion 12b, the bundle discharge straw is guided by the inclination of the guide surface portion 12b with respect to the longitudinal direction of the machine body and the pop-out force of the bundle discharge straw, so that the bundle discharge straw is as shown in FIG. It is configured to move to the tip side. In short, with respect to the bundle discharge straw that jumps out from the binding space S by the release action of the release arm 11, the stock edge alignment is performed so that the bundle is displaced to the tip side rather than the position when bound in the binding space S and falls to the field. The member 12 operates toward the tip side by both the tapping action by the tapping and aligning action part 12a and the moving action by the guide surface part 12b.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
