A deck 12 is installed at the rear of the upper surface of the sorting cover part 8a, and a cover 13 with a rear lower part opened rearward is attached, and a binding machine A is installed on the deck 12. is equipped with a binding part a that straddles the deck 12 and has a packer 14 and a needle 15 on the bottom, a knot cover 16 on the top, and a door 17 on the back. Equipped with discharge arms 1.1', 1'' which rotate in the trajectory of 10 is transferred on the deck 12, and in a horizontal and lateral direction, is tied from the middle part to the tip side by the binding part a, and the bundle of straw C in the horizontal and lateral direction is tied at the binding position a to the culm. Release arm 1 over the side
．． 1'.

1" is configured so that it can be hooked and released backwards as it is.

A support rod 19 is erected at the rear of the side of the deck 12 that supports the tip side of the straw bundle C in the bundling part a, and a cylindrical metal 20 is rotatably fitted to the upper end of the erected support rod 19. A base 2a of a long hammered arm 2 extending toward the rear side of the binding part a is fixedly attached to the base 2a of a long hammered arm 2, and the arm 2 moves forward and backward 1 around a fulcrum O, which is the axis of the support rod 19. The arm 2 is configured to be rotatable, and a support cylinder 21 is fixed to the tip of the rotatable arm 2 in the front-rear direction.

In addition, two claws 22.22 are provided on the upper side in parallel in the forward direction, and one claw 2 is provided in the middle lower side of the claws 22.22 in the same direction as the claws 22.
A supporting shaft 25 extending rearward from the base 24 of the straw receiving body B having a U-shaped side surface that receives and clamps the tip side of the straw bundle C on the deck 12 is attached to the supporting cylinder 21. The straw receiving body B is configured to be able to freely reciprocate rearward from the straw position on the deck 12 on the tip side, and is also rotatably mounted around the axis of the support shaft 25 in the front and rear direction. Set up

Further, a support piece 26 is provided vertically from the lower surface of the base 24 and extends forward from the upper part of the support rod 19.
7 and the lower end of the support piece 26 are connected by a tension spring 3 of a predetermined length.
is rotated forward and the straw receiving body B is in the straw receiving position on the deck 12 on the tip side and no tensile force is applied to the tension spring 3 of a predetermined length. 2
2 is on the upper side and the claw 23 is on the lower side, and hold the straw receiver B.
is located between the bundling position A and the tip of the straw bundle C in the bundling part a, and the tip side of the straw bundle C is caught and held between the claws 22, 22 and 23, and then the discharge arm 1. 1',
The straw receiving body B is configured to move backward as the arm 2 rotates rearward about the fulcrum O due to the rearward discharging force of the straw bundle C by 1', and is linked to this forward movement. Then, as shown in FIG. 6, the distance between the supporting pieces 27 and 26 becomes large, and a tensile force is generated in the tension spring 3, which is not currently under tension, and the supporting pieces 2.6 are pulled toward the supporting piece 27. As a result, the straw receiver B rotates approximately 90 degrees around the axis of the support shaft 25 in a positive direction with the culm side facing downward as shown by the arrow in FIG. It is configured to move back forward due to the restoring force of the spring 3.

By this backward movement, the tensile force of the tension spring 3 is gradually released, and the gap between the support pieces 26 and 27 becomes smaller and returns to its original state, while the tension spring 3 becomes a predetermined length and the support piece 2
6 to the side opposite to the supporting piece 27 side, and the straw receiving body B is rotated by approximately 90 degrees in the opposite direction to that described above to restore the straw receiving state.

Next, two culm guide rods 4, 4 are installed vertically at a distance in the horizontal direction behind the deck 12 that supports the culm side of the straw bundles C bound in the binding part a. , the lower end portion 4a of the culm guide rods 4,4.

4a is placed at the roadside and the upper ends 4b are fixed to the cover 13 with bolts 28.

Further, a rod body 5a connected to the lower part of the support rod 19 extends laterally below the rear side of the deck 12, and its end side is bent to form a culm receiving rod 5 in the front-rear direction.

The culm receiving rod 5 is provided horizontally below the straw receiving body B so as to reciprocate in the front-rear direction and below the lateral sides of the culm guide rods 4, 4.

The straw 10 threshed during the combine harvester operation is carried out backwards by the straw checker 711 and sent onto the deck 12. At the bundling part a, the packer 14 forces the straw 10 toward the door 17, and when a certain amount is reached, the needle 15 Bind the straw bundle C by wrapping the binding string around it and using the release arms 1.1' and 1''.
is released backwards.

In that case, as shown in FIG.
The straw receiver B, which is held in a position with the lower side, has claws 22.
The tip side of the straw bundle C is caught and held between the nails 23 and the straw,
From this state, the ejection arms 1.1', 1'' forcefully eject the material backward as shown by the arrow.

As a result of this release, the culm side of the straw bundle C moves to the culm guide rod 4,
4, the heavy culm side falls downward along the culm guide rods 4, 4, and the tip side falls down from the above discharge arm 1.1.
As shown in FIG. 8, the ejection force of ', 1'' presses the straw receiver B backward and moves it backwards around the fulcrum O. In conjunction with this forward movement, the tension spring 3 of a predetermined length applies a tensile force. As a result, the support piece 26 of the straw receiver B is pulled toward the support piece 27 side, and the straw receiver B is rotated approximately 90 degrees around the axis of the support shaft 25 in the positive direction with the culm side facing downward as shown by the arrow. Since the straw bundle C is moved, the claws 22, 22 located on the upper side and the claws 23 located on the lower side face each other in the left and right directions, thereby changing the straw bundle C into a standing position.

At this time, as shown in FIG. 9, the middle part of the straw bundle C is stopped by the culm receiving rod 5, and the entire straw bundle C is securely in a vertical position, and the straw receivers of the claws 22, 22 and 23 are held. The tip of the head, which had been exposed, fell down as shown by arrow 2 and was left on the ground in an upright position.

When the straw bundle C is pulled out and falls from the straw receiver B, the straw receiver B moves back and forth forward about the fulcrum O due to the restoring force of the tension spring 3 of a predetermined length. The tensile force gradually disappears, and the distance between the support pieces 26 and 27 becomes smaller, causing the tension spring 3 to return to its predetermined length.As a result, the support piece 26 is pushed toward the side opposite to the support piece 27, and the medicine body B is rotated approximately 90 degrees in the opposite direction to the above to restore the barley state to the position on the tip side of the barley.

In this way, the straw bundles C bound and discharged by the binding machine A are left one after another in an upright position on the ground, as shown in FIG.

As explained above, the present invention is configured to bind straw culms in the direction of horizontal lateral force using a tying machine installed at the rear of the machine body, and to release the straw bundles rearward using a discharge arm to make them stand upright. In the straw bundle upright discharge device in the bundling section of a combine, the barley body that holds and holds the tip side of the straw bundle is configured to be able to reciprocate backwards from above the deck on the tip side, and is linked to this reciprocating movement. The straw bundle is installed so that it can be rotated in the forward and reverse directions, with the culm side facing downward, around the axis of the support shaft in the front-rear direction, and the straw bundle released by the release force of the release arm causes the above-mentioned When the medicinal oat body moves backward, the medicinal oat body is rotated in the above-mentioned positive direction, and the straw bundle is adjusted to an upright position and falls to the ground, so that the tied straw bundle is released by the discharge arm. When the straw is released forcefully backwards, the barley body receives and clamps the tip side of the straw bundle, moves backward, and then rotates in the positive direction with the culm side facing downward, so that the tip side is not caught. In this state, the heavy culm side tries to fall downward due to its own weight, which promotes the posture change operation, quickly and smoothly corrects the posture to an upright position, and allows it to fall to the ground, thereby allowing the straw bundle to stand up and leave it. This makes it possible to improve the air permeability of the straw bundles, speed up drying, and make effective use of the straw, which has the advantage of being suitable for implementation.
