Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for feeding waste straw from the terminal end of a waste straw conveying device of a combine to a binding machine disposed below.

In a combine harvester or the like, when reaping work is performed while discharging bundled waste straw to the rear, it is desirable to discharge the straw bundles toward the harvested side in a posture parallel to the direction of movement of the machine.

This is because if the waste straw bundle is released into the field while being carried by the waste straw conveying device, that is, in an attitude perpendicular to the direction of movement of the machine, the cutting width will be small if the combine is small. This is because, during the next reaping, when passing near the bundle of waste straw that has been released sideways, there is a tendency to step on the bundle of waste straw.

Therefore, this invention changes the orientation of the straw from perpendicular to the direction of movement of the combine to one along the direction of movement of the combine during the feeding process from the straw conveyance chain to the tying machine. By supplying the waste straw bundles to the tying machine, even if the bundles of waste straw discharged from the tying machine are released as they are, they fall onto the field in an attitude along the direction of movement of the combine harvester. This is what we propose.

To explain the embodiment with reference to the drawings, in the figure, 1 is the main body of the combine, 2 is a tying machine attached to the rear part of the combine, and the waste straw is transported in the chain direction by a waste straw conveying chain 3 and a coil spring, which are known means. The waste straw is conveyed to the upper side of the binding machine 2 by a waste straw conveying device consisting of a waste straw guide rod 4 which is biased towards the waste straw, and the waste straw feeding device 6 to the binding machine 2 according to the present invention is disposed between the terminal end of the waste straw conveying device 5 and the binding machine 2, and is configured as follows.

That is, the waste straw feeding device 6 according to the present invention is configured with a pair of a transport unit 6a on the tip side and a transport unit 6b on the stock side, and each transport unit 6a,
6b is an endless conveyor belt 8a which has the same structure and has protrusions on its outer periphery.

8b, and the pulleys 9a and 10a that rotate it.

9b, 10b, and guide rails 11a, 11b arranged along one side of the conveyor belts 8a, 8b. Between 9a and 10b, the rotation planes of each pair of pulleys are set to be perpendicular to each other, and the pulleys 9a and 9 on the starting end side
b are disposed on both sides of the terminal end of the waste straw conveying device 5, and the pulleys 10b and 10a at each terminal end are disposed in the front-rear direction of the combine along the conveying direction of the conveying device 5. , is located facing the entrance of binding machine 2,
The pair of conveyance units 6a and 6b are twisted approximately 90 degrees from the start end to the end end in a virtual plane including the conveyor belts 8a and 8b, respectively.

In addition, in the figure, 13 is a string guide plate, 14 is a packer,
15 is a door, 16 is a needle, and 17 is a discharge arm.

Since the supply device 6 according to the present invention is configured as described above, it operates as follows.

That is, when the waste straw A is conveyed by the conveyance chain 3 to the starting end side of this feeding device 6 in a state lined up horizontally with respect to the traveling direction of the combine, it constitutes a pair of conveyance units 6a and 6b. The protrusions protruding from the outer periphery of the conveyor belts 8a and 8b allow the conveyor belts 8a and 8b to remain in the same position.
The receivers are passed on conveyor belts 8a and 8b, and the tip side is conveyed by the tip side conveyance unit 6a and the stock side by the stock side conveyance unit 6b, respectively, toward the entrance of the binding machine 2. As mentioned above, in the conveying device 6 according to the invention, each of the conveying units 6a and 6b is twisted approximately 90 degrees from the starting end to the terminal end, with the plane including the conveying belts 8a and 8b. Therefore, the transport posture of the waste straw in plan view is the same as that of the pair of transport units 6a, 6.
b, so that the pulley 10b and the pulley 10a can be rotated by about 90 degrees.
and are arranged in the front and back direction of the combine,
On the starting end side of the supply device 6, the shredded straw A is transferred onto the pair of transport units 6a, 6b in a side-by-side posture, and on the terminal end side, the shucks A are along the traveling direction of the combine harvester and on the side of the stock. Hold the position with the tip side facing forward and the tip side behind you.
It will be supplied to the binding machine 2.

Therefore, in the feeding device of the present invention, if the length of one conveying unit 6b is made shorter than the length of the other conveying unit 6a, the conveying distance on the plant head side is longer than that on the ear side. Even if the feed speeds of both conveyor belts 8a and 8b are set to be the same, the straw A will inevitably pass through the tying machine with the stock side in a leading position. They are then sent into the plant, tied up in this position, and released into the field.

In other words, the tied waste straw is placed at the rear of the combine harvester.
The straw is discharged with the direction of the straw culm aligned with the direction of travel of the combine harvester.

As can be easily understood from the above explanation, according to the straw feeding device according to the present invention, the posture of the straw is changed between the end of the straw conveying device and the tying machine. A pair of conveying units whose planes including the conveying bodies are twisted by 90 degrees are used to convert the position perpendicular to the direction of movement of the combine into the position along the direction of movement of the combine. Therefore, the change in posture is performed extremely smoothly, and the waste straw is changed in posture in this way before being tied in the binding machine, so the tied waste straw is Even if you drop the waste straw onto the field, the direction of the waste straw bundles will be aligned in a vertical line along the direction of movement of the combine harvester, so there will be no confusion during the next reaping. Since the bundle of waste straw bundled is already in the vertical direction inside the binding machine, it is easily possible to forcibly guide it to the side of the machine body, that is, to the already-cut side, and release it.

In addition, in the feeding device of the present invention, if the conveyance distance on the tip side is made slightly longer, it is possible to stabilize the tying work in the tying machine and reduce tying errors by allowing the tying machine to perform the tying operation in advance.
