Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for discharging bundled straw in a combine harvester.

In other words, in a combine harvester configured with a bundling device installed inside the cover at the rear of the machine, the bundling straw sent out from the bundling device is released into the field on the harvested side as far away as possible from the uncut side. It is designed to be able to be left upright in a state where it is easy to dry, and can be attached to the rear of the aircraft if necessary, and has a lightweight and robust structure, making it easy to carry out. This is what we provide.

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

Fig. 1 shows a schematic plan view of a combine harvester, in which a reaping conveyance section 8 is installed at the front part of the entire machine body, which is closer to the uncut side, and a threshing section 9 is installed at the rear thereof, and a part of the rear cover of the threshing section 9 is installed. A straw removal chain 11 is installed on the foot chain 9a to inherit the waste straw from the foot chain 10 and carry it out to the rear. A conventional bundling device 2 for bundling the waste straw sent out from the straw waste cheno 11 is installed, and the rear part of the cover 1 is opened so that the bundling straw 4 bound by the bundling device 2 can be discharged rearward. On the right side, a driving section 12 is installed at the front, and a paddy receiving section 13 is installed at the rear, and the structure is similar to that of the conventional type.

A is a long discharge cheno, which grips the tip side of the bundled straw 4 discharged from the binding device 2 and conveys it with the culm side hanging down, and approaches the starting end 3 to the binding device 2 so that it can be discharged from the terminal end 5. At the same time, it is installed diagonally so that the terminal end 5 extends diagonally to the upper part of the rear side in the direction of the cut side of the machine body.
A support rod 14 extending from the inside near the starting end 3 of the discharge chino A is removably fixed to the rear lower part of the cover 1 with a bolt or the like, and the tip end 15 of the long transmission case B is attached to the discharge chino A. The flange portion 18 at the base 17 of the transmission case B is attached to the side of the cover 1 by bolts, etc. It is configured such that it is removably fixed and can transmit power from the transmission part of the binding device 2 to the bevel gear 19 in the base 17.

In addition, a mounting part 20 is installed at the other end of the long support rod C, one end of which is connected to the part approaching the tip 15 of the transmission case B, and the mounting part 20 is attached to the top surface of the cover 1 by bolts or the like. The discharging cheno A, the transmission case B, and the support rod C are configured to extend in a pyramidal shape while the discharging cheno A, the transmission case B, and the support rod C are fixed in a removable manner through the discharging chimney.

A clamping rod 7 is provided oppositely on the clamping surface of the discharge cheno A from the starting end 3 side to the terminal end 5 side, and the clamping rod 7 is supported on a support frame 21 that supports the discharging cheno A from the inside side. Multiple supports 2
2 are respectively inserted into the racks, and the levers 7 are clamped by the ammunition 23.
is installed so as to press against the discharge chain A side.

Reference numeral 6 denotes a fall guiding chute, which extends in a bent shape corresponding to the terminal end 5 of the discharge cheno A, and can guide the bundling straw 4 released from the terminal end 5 so that it falls with the culm side facing downward. A support metal 24 at the base of the shooter 6 is rotatably supported on a support pin 25 supported from the inner side of the terminal end 5 of the discharge chino A, and an arm fixed to the support pin 25. One end of a bent lever 27 is rotatably connected to the tip of the lever 26 via a pin 28.
The tension spring 28 connects the tip of the support metal 24 with the tip of the
On the other hand, at the end of the support frame 21, the middle part of a bellcrank-type movement rod 30 is pivotally supported via a pin 31, and one end side of the movement rod 30 is joined to the tip of the support rod 22. , the other end of the rod 32 connected to the other end side of the interlocking rod 30 is connected to the intermediate portion of the lever 27. 5 Therefore, when using the ejection device, the flange portion 18,
When the mounting part 20 and the support rod 14 are fixed to the predetermined positions of the cover 1 with bolts, etc., the transmission case B, the support rod C, and the discharge chain A are moved from the cover 1 side toward the upper part of the diagonal rear side, as shown in the figure. can be assembled so that the entire structure extends into a pyramidal shape.

During work, when the waste straw is tied by the binding device 2 in the cover 1 while the power is being transmitted from the inside of the transmission case B to the discharge chino A, the bundled straw is released from the binding device 2 as it is. The tip side of the straw 4 is inherited by the starting end 3 of the discharge chain A, and the tip side of the bundle straw 4 is held between the discharge chain A and the clamping rod 7, and the culm side hangs down.
The bundled straw 4 released from the terminal end 5 is not guided into the chute 6 but falls in an upright shape, and the culm side touches the field as shown in Fig. 4. It is left standing in an upright position as shown in the figure.

In that case, the tied straw 4 is left in the field on the cut side, which is quite far away from the planted culm side, which is the uncut side.

If the bundling straw 4 discharged from the terminal end 5 of the discharging cheno A gets caught in the chute 6 and becomes clogged, it will be pushed by the bundling straw 4 and the chute 6 will be moved as shown in FIGS. 7 and 9. As shown by the imaginary line in the figure, it rotates around the support pin 25 and opens outward to remove the clogged bundling straw 4.
falls as it is, and as the tension spring 29 passes over the fulcrum, one end of the interlocking rod 30 pushes the support rod 22 as shown by the solid line in FIGS. Press the support rod 7 and press the support rod 2
2 rotates the interlocking rod 30, the rod 32 is hooked, and the shooter 6 moves back toward the end portion 5 again to return to its normal guiding position.

In this way, the present invention is a combine harvester in which the bundling device 2 is installed in the cover 1 at the rearmost part of the machine body, in which the tip side of the bundling straw 4 is transferred from the bundling device 2 to the starting end 3 and transported as it is to the terminal end. A discharging chino A that can be dropped from part 5 with the culm side facing downward is installed diagonally so that the terminal part 5 extends higher from the rear side of the binding device 2 toward the cut side of the machine body. The discharging cheno A, the transmission case B that is transmission connected to the terminal end of the discharging chino A, and the support rod C that supports them are extended in a pyramidal shape as a whole, and each can be attached to and detached from the cover 1 or the main body side. Because I configured it by connecting it to
The bundling straw 4 sent out from the bundling device 2 can be carried out by the discharging cheno A and left standing in the field on the cut side as far away as possible from the uncut side in a state where it can easily dry. The ejection cheno A, transmission case B, and support rod C can be assembled in a pyramidal shape, although they extend diagonally, to create a sturdy mounting structure, which makes the entire structure lightweight and easy. It has the advantage of being able to be suitably implemented with a simple structure.
