Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a focused three-dimensional discharge device for bundled straw in a combine harvester.

That is, at the rear upper part of the tying machine at the rear of the machine, a discharging conveyance chain and a pinching rod are extended so that the tying straw can be held in an upright position, conveyed, and discharged three-dimensionally from the rear upper part to the ground. A combine harvester with a simple structure that can collect several bundles of tied straw and release it three-dimensionally at once, and when collecting the tied straw after the fact, it can be collected efficiently and easily. This is an idea that we would like to offer.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a side view of the combine harvester, in which a reaping part C is installed in front of a threshing part B mounted on a machine body supported by crawlers 7, and a reaping part C is installed in front of a threshing part B mounted on a machine body supported by a crawler 7, and inside a binding cover 8 connected to the rear of the threshing part B. is equipped with a tying machine A, and the straw is carried to the tying machine A from the rear upper part of the threshing section B by a straw discharging chain 9, and the tying machine A binds the straw one bundle at a time and discharges it to the rear. It is constructed in the same way as the conventional structure.

At the rear of the tying machine A, a discharging conveyance chain 1 for standing up, pinching and conveying the tying straw that is discharged from the tying machine A, and a pinching rod 2 are installed in correspondence with each other and extending diagonally toward the rear and upper part. , support rods 10, 10 extending from the pincer rod 2 are interposed with ammunition 11, 11 to form a support frame 1.
At the same time, the other end side of the connecting rod 13 connected to the supporting frame 12 and extending upward is connected to the supporting frame plate 14 of the conveying chain 1, and extends from the side of the binding machine A. The upper part of the transmission case 15 is connected to the terminal end of the conveyance chain 1 so that the conveyance chain 1 can be supported together with the stay 16.

On the terminal end side of the pinching rod 2, a support shaft 17 is attached to the starting end of an extending rod 2a similar to the pinching rod 2 at the terminal end of the pinching rod 2.
The extending rod 2a is configured to be freely rotatably connected to the conveyor chain 1 through the conveyor chain 1, and the extending rod 2a
The end of the support rod 10a is rotatably connected to the portion of the support rod 10a near the terminal end side via a support shaft 18, and the support rod 10a
A bullet 11a is inserted into the supporting frame 12 so as to be slidable therein, and a guide frame 19 is provided on the outer surface of the extending rod 2a near the starting end so that the internal space becomes a rectangular rectangle.
Configure by connecting them.

Further, a conveyor chain 1 corresponding to the extension rod 2a
A guide body 3 is installed on the terminal end side of the conveyor chain 1, and the starting end of the guide body 3 is pivotally supported on the support frame plate 14 via a pin 20 and attached to the conveyance chain 1 side so as to be freely retractable. be. Further, a spring 22 is interposed between the end side of the guide body 3 and the support piece 21 on the support frame plate 14 to press the guide body 3 toward the extending rod 2a. The other end of the U-shaped operating rod 5 whose free end is fitted inside the guide frame 19 is inserted into the guide body 3 so as to be rotatable, and is fixed to a portion near the other end of the operating rod 5 to form an integral structure. A stopper 4 made of rod is connected to the guide body 3.
A support rod 23 is provided extending between the guide member 3 and the extension rod 2a, and protrudes from the upper surface of the guide body 3 with which the stopper 4 abuts.

Therefore, when working with a combine harvester, the binding machine A
The bundled straw is released and is held between the conveyance chain 1 and the clamping rod 2 and conveyed to the rear upper part in an upright state. As shown in FIGS. 2 to 5, the stopper 4 is in a state spanning between the guide body 3 and the extending rod 2a until the binding straw fed out between the guide body 3 and the extending rod 2a presses against the stopper 4. The bundled straws being conveyed one after another are held together in a gathered state as shown in FIG. 5 between the extending rod 2a and the guide body 3, which are pressed.

In this way, when the bundling straw is completely sandwiched between the extending rod 2a and the guide body 3 as shown in FIG. Then, the stopper 4 rotates as shown by the arrow B, and then, as shown in FIG.
The extension rod 2a is pushed open and separated from the conveyance chain 1 through the operating rod 5, and the stopper 4 also abuts against the support rod 23, causing the guide body 3
is moved back into the conveyor chain 1 side, and the space between the extending rod 2a and the guide body 3 becomes wide open, and the several bundles of tied straw that are gathered between them fall at once, as shown in Figure 1. As shown, several bundles are collectively emitted in three dimensions. Immediately thereafter, the extending rod 2a and the guide body 3 move back as shown in FIGS. 2 to 5.

In this way, the present invention has a discharging conveyance chain and a clamping rod extending from the rear upper part of the tying machine at the rear of the machine so that the tying straw can be conveyed in an upright state between the clamps and discharged three-dimensionally from the rear upper part to the ground. In the combine harvester, a guide body is attached to the terminal end side of the conveyance chain, and the guide body is retractable to the conveyance chain side, and the terminal side of the clamping rod corresponding to the guide body is attached to the terminal side of the conveyance chain, and In addition to being composed of an extending rod, an operating rod whose tip end side is fitted into the extending rod side is rotatably inserted into the guide body, and a stopper formed integrally with the operating rod is extended from the guide body side. A supporting rod is provided that extends toward the rod, and a stopper abuts against the guide body, and the extending rod is separated from the conveying chain via the operating rod due to the pressing action of the bundling straw against the stopper. Since the guide body is moved back into the conveyance chain almost simultaneously when the stopper collides with the support rod, the bundled straw being conveyed is bundled into several bundles between the guide body and the extension rod. When it reaches a state where it accumulates, the stopper rotates under the pressure of the subsequent bundled straw, and the corresponding extension rod is separated from the conveyance chain.
In addition, the guide body moves back into the conveyance chain side, and the space between the extending rod and the guide body widens widely. Therefore, although it has a simple structure, it is possible to collect several bundles of bundled straw and discharge it three-dimensionally at once. Since this can be done reliably, the bundled straw can be efficiently and easily collected after the fact, and has the advantage of being suitable for collection.
