Description

[Detailed description of the invention] The present invention is designed to transfer the culm bundles bound by the culm tying machine at the rear of the machine in a combine harvester that pinches and conveys the culm bundles to the side of the machine, which has already been cut, and then releases them. It is related to the device.

Conventionally, in a combine harvester equipped with this type of waste culm binding machine, the stock part of the bundled waste culm bundle is held and conveyed between a clamping rail and a waste culm bundle conveyance cheno, and is transferred to the cut field side on the side of the machine. Therefore, when cutting through the center of the field to cut through the middle of the field, both sides of the machine are uncut.
Discarded culm bundles are released onto uncut land, and especially when the discarded culm tying machine is configured to be movable in the left and right directions so that the bundling position can be varied, it is difficult to tie the discarded culm bundles on the tip side. This has the disadvantage that the released culm bundles become a hindrance to the next reaping operation as they are released into the uncut field.

The present invention was devised in view of the above-mentioned actual situation, and although it is possible to release the culm bundle to the side of the machine on the side of the cut field during normal reaping work, it is possible to During reaping work, the waste culm bundles that are carried by the sides of the machine can be discharged directly from the intermediate transport position before reaching the end of transport to the rear of the machine, thereby preventing the waste culm bundles from being released to the uncut field side. It is an object of the present invention to provide a conveying device for a discharged culm bundle in a combine harvester.

The structure of the present invention will be explained based on an embodiment shown in the drawings. Reference numeral 1 denotes a culm binding machine mounted on the rear part of a combine harvester, and the culm binding machine 1 is threshed in a threshing section 2. The waste culms that have been processed and transported to the rear of the machine via the waste culm conveyance belt 3 are collected and bundled in a predetermined amount, and then thrown backward.

Behind the tying machine 1, there is a discarded culm bundle A thrown out from the tying machine 1.
The upper clamping rail 5 and the lower discharging culm bundle conveying cheno 6 clamp and convey the culm bundle to the mowed field side on the side of the machine, and then discharge it.

The tying machine 1 and the discharged culm bundle conveying device 4 are integrally configured via a connecting bracket 7, and the tying machine 1 has a fixed frame 8 provided laterally in the left and right directions at the rear of the machine body. By moving the movable frame 9 at the bottom of the binding machine in the left-right and lateral directions, the binding position can be freely changed by moving together with the discharged culm bundle conveying device 4.

Incidentally, reference numeral 10 denotes a fastener provided on the movable frame 9 in order to restrict movement of the movable frame 9 on the fixed frame 8.

In this embodiment, the holding rail 5 is as shown in FIG.
Front rail 11. Middle rail 12 and rear rail 13
The intermediate rail 12 is divided into two parts, and the intermediate rail 12 is divided into two parts.
The connecting rod 14a is connected to the connecting rod 14a, which is always biased downward.

The rear end of the intermediate rail 12 and the front end of the rear rail 13 are pivotally supported via a support shaft 15, and are hinged with one piece fixed to the intermediate rail 12 and the other abutting the rear rail 13. 16 and is screwed onto the rear rail 13.
The discharged culm bundle A that has been conveyed by the pinching is transferred to the discharged culm bundle conveyance Cheno 6.
There are two positions: a clamping position where the culm bundle is clamped and transported to the rear end of the transport (as shown by the solid line in FIG.
It is configured so that it can transform into the state shown by the imaginary line in FIG. 3).

A base end portion of a stopper 17 is fixed to the intermediate rail 12 side of the hinge 16, but a distal end portion of the stopper 17 extends in a direction along the rear rail 13 in the non-clamping position.

The rear rail 13 is fixed to the rear rail 13 by fixing the head 18a to the rear rail 13 through a fastening elongated hole 1 bored in the other part of the hinge 16.
Both rails 12,
When the rear rails 13 are fixed in substantially the same straight line, they are fixed at the clamping position, and when the rear rail 13 is moved upward and fixed to the stopper 17, the tip of the tip-side guide rail, which will be described later, is aligned with the culm bundle. It is arranged to be fixed at a non-clamping position located lower than the tip side conveyance path of A.

Reference numeral 19 denotes a tip-side guide rail located on the conveying end side of the holding rail 5 and provided on the tip side of the discharged culm bundle conveying position 4. The guide rail 19 is made of an elastic member, and its base is The end portion is connected and fixed to the middle portion of the rear rail 13 via a connecting rod 20.

The guide rail 19, which is located closer to the tip side than the rear rail 13, is located slightly lower than the lower edge of the rear rail 13, and is arranged approximately parallel to the lower edge of the rear rail 13. , the tip extends forward from the front end of the rear rail 13, and when the rear rail 13 is in the clamping position, the tip side guide rail 19 extends to the rear of the intermediate rail 12, as shown in FIG. It guides the tip side of the discharged culm bundle A that is being pinched and conveyed.

On the other hand, when the rear rail 13 is located at the non-clamping position, the tip of the guide rail 19 is located lower than the tip side conveyance path of the discharged culm bundle A, and the tip side of the discharged culm bundle A is placed above the guide rail 19. It is designed to brake the conveyance of the tip side by bringing it into contact with the edge.

Next, the operation of the present invention constructed as described above will be explained.

The waste culms threshed in the threshing section 2 are conveyed to the waste culm binding machine 1 by the waste culm conveying belt 3, and the culm end side, which has been tied by a predetermined amount, is thrown backward.

The thrown culm bundle A is received at the starting end of the conveyance between the clamping rail 5 and the discharged culm bundle conveyance cheno 6, and is conveyed in a pinched manner to the side of the machine.

Here, in a state where the rear rail 13 is fixed in the clamping position, the discharged culm bundle A is released to the mowed field side on the side of the machine body as before.

At this time, the lower edge of the tip side guide rail 19 serves as a guide rail for the discharged culm bundle A, so that the tip side of the discharged culm bundle A can be smoothly conveyed and guided.

On the other hand, when performing a so-called mid-cut reaping operation that cuts through the center of the field, the rear rail 13, which is in the clamping position, may be moved to the non-clamping position.

To do this, after releasing the tightening tool 18 that fixes the rear rail 13 in the clamping position, the rear rail 13 is rotated upward to the non-clamping position using the support shaft 15 as a fulcrum, and then the clamping tool 18 is used to The rear rail 13 may be fixed to the stopper 17.

When the middle-splitting reaping operation is started after the rear rail 13 is fixed in the non-clamping position in this way, the discarded culm bundle A that is clamped and conveyed by the clamping rail 5 and the discarded culm bundle conveyance cenograph 6 is moved to the intermediate part. When reaching the terminal end of the rail 12, the tip side guide rail 1 is located lower than the tip side conveyance path of the discharged culm bundle A.
Although the tip side comes into contact with the upper edge of the guide rail 9 and is braked, the tip side guide rail 19 is pressed downward and elastically deforms because the discharged culm bundle A is still being conveyed.

Then, when the discharged culm bundle A reaches the portion of the rear rail 13 in the non-clamping position, the clamping action of the discharged culm bundle A is released, and the pressing force of the tip-side guide rail 19 is also released at the same time.

As a result, the discharged culm bundle A whose clamping action has been released is caused to lift up the tip side due to the return action of the tip side guide rail 19, and is dropped to the rear of the machine as it is.

Therefore, even in the middle-splitting reaping operation, the discharged culm bundle A will not fall to the uncut field side.

This means that when the discharged culm binding machine is able to move left and right to change the binding position as in this embodiment, the binding machine 1 is moved to the end of the conveyance on the side of the machine in order to bind the culm on the tip side. This is particularly effective when the discarded culm bundle A is displaced to the side.
Since the tip side of the culm bundle A is pinched and conveyed, the center of gravity of the discharged culm bundle A is closer to the stock base than the pinching position, and the fall to the rear of the machine becomes more reliable.

In addition, when performing normal reaping work after completing the intermediate reaping work, the rear rail 13, which is in the non-clamping position, may be moved to the clamping position by the above-mentioned reverse operation.

Further, in the above embodiment, the clamping rail 5 is divided into three parts, but the invention is not limited to this; in short, the rear rail 13 of the clamping rail 5 can be transformed into a clamping position and a non-clamping position. Furthermore, when the rear rail 13 is in the non-clamping position, the tip side guide rail 19
Any device that applies braking to the tip side is sufficient.

In summary, in the present invention, the waste culm bundles bound by the waste culm tying machine at the rear of the machine are held and conveyed by the clamping rails and the waste culm bundle conveying cheno, and are discharged to the side of the machine on the side of the mown field. In the combine harvester, the conveyance terminal end of the clamping rail is constituted by a rear rail that can swing to a non-clamping position with the front side as a fulcrum, and the base end of the rear rail is connected and fixed to the rear rail on the tip side of the rear rail. Since the tip side guide rail is arranged such that the tip side extends in the direction of the conveyance start end, and the tip side guide rail is configured to apply a brake to the tip of the discharged culm bundle when the rear rail is not clamped, the rear rail is , which is normally located in a clamping position opposite to the discarded culm bundle conveyance cheno, transports the discarded culm bundle together with the tip side guide rail, and discharges the discarded culm bundle to the side of the machine on the mown field side, but the rear rail is not clamped. Once the discarded culm bundle is transformed into the position, the conveyance of the tip side of the discarded culm bundle is braked by the tip side guide rail, and the clamping and conveyance of the discarded culm bundle by the rear rail is released, so that the discarded culm bundle is Since the culm is discharged to the rear of the machine rather than to the side of the machine, the waste culm bundles discharged from the conveyance device are not discharged to the uncut field side during split reaping work. It is possible to prevent the discharged culm bundle from interfering with the next reaping operation, thereby improving work efficiency.
