DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting part structure of an all-culm input type combine harvester in which only a granulated part is sent to a threshing apparatus by a two-stage cutting structure. It is related to processing.

[0002]

2. Description of the Related Art Japanese Unexamined Utility Model Application Publication No.
No. 9521 is known. First, a stem cutting is cut from a root by a first cutting device on the lower side, and immediately below the granulated portion by a second cutting device on the upper side immediately after. by doing,
Only the necessary tip is sent to the threshing device. Then, the stems and stems are sent to the second cutting device while being conveyed backward in the sandwiched state by the sandwiching and conveying device, so that the cutting can be reliably performed below the granulated portion.

[0003]

In the combine having the above structure, the root portion cut by the second cutting device is sown in the field as it is. For this reason, it is convenient to pour in the roots that were sown at the time of subsequent plowing, but it is not suitable for recovering the roots later, which is inconvenient depending on the type of post-processing. There seems to be room for improvement. SUMMARY OF THE INVENTION An object of the present invention is to provide a combine harvester capable of coping with post-processing for recovering the remaining stock portion.

[0004]

In order to achieve the above object, the present invention provides a first cutting device for cutting a stem of a planted stem,
A first transport device for nipping and transferring the stems and stems cut by the first cutting device in an upright posture, and a second transporting device for cutting the lower side of the granule portion of the stem and stems transported by the first transport device. A cutting device, and a second transporting device for transferring the granulated portion cut by the second cutting device to a threshing device, and the stem and stem cut by the second cutting device below the second cutting device. It is characterized in that a lateral feeder is provided for laterally transporting the root of the stock and collecting it at a predetermined position within the cutting width.

[0005]

In other words, the traversing device disposed below the second cutting device can collect the harvested root portion at a predetermined position in the left-right direction. It is possible to place the root portion of the stock on the field so that the subsequent collecting operation can be performed efficiently. If the traversing device is not operated, the stock portion can be sowed as it is. In the reaping section having a structure in which cutting is performed first at the base of the stock, and thereafter, the spike side is cut, the graining section is configured to be transported to a threshing apparatus through a path above the second cutting apparatus. Since the traversing device can be arranged below the device and can be arranged immediately after the first cutting device, a dedicated feeding mechanism for feeding the stock portion to the traversing device is unnecessary. .

[0006]

Therefore, the addition of the traversing device utilizing the basic structural arrangement and the arrangement of the traversing device make it possible not only to sow the base portion of the stock but also to make it suitable for the collecting operation. The structure could be provided.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows an all-culm input combine, wherein 1 is a cutting unit, 2 is a threshing unit, 3 is a control unit, 4 is a crawler traveling unit, 5 is an unloader, and 6 is a traveling unit. Reaper 1
Is a vertical weeding device 7, a raising device 8, first and second cutting devices 9 and 10 having a clipper structure, a nipping and conveying device (corresponding to a first conveying device) 11, a lateral feeding device 12, and an auger. 13 and a base portion B provided with a rear transfer device (corresponding to a second transfer device) 14 are detachably connected to each other, and the base portion B can be moved up and down around a horizontal axis P. Is attached to the traveling body 6.

The action of the mowing unit 1 will be described in brief. The planted stem culm weeded by the weeding device 7 is raised to a standing posture by the device 8, and the culm is moved by the horizontal rotation type nipping and conveying device 11. Feed backward while supporting the middle part of the body. In this state, first, the lower first cutting device 9 cuts off from the base of the stock, and immediately thereafter, the upper second cutting device 10 cuts the portion immediately below the grained portion in the holding position of the tip side by the holding and conveying device 11. Then, only the grained portion on the tip side is laterally fed by the auger 13 and the rear transport device 14
To the threshing apparatus 2. The stock portion cut by the second cutting device 10 is collected by the traverse device 12 at a position slightly to the right between the left and right crawler traveling devices 4 and 4 and is sown on the field. Next, the lateral feed device 12 will be described.

As shown in FIG. 1 and FIG.
Is configured as a screw conveyor type in which a screw 15 having a left and right axis Z that rotates in conjunction with an auger 13 is disposed on a guide cover 16. The guide cover 16 has two holes 1 and 2 from the right.
7 are formed, and the stock portion of the right two ridges is the right spiral 1
While being sent to the left at 5R, the stock root portion of the four left streaks is sent to the right at the left spiral part 15L and dropped into the field through the pit 17. The guide cover 16 is attached to a lateral bracket 19 via a hinge 18,
The horizontal bracket 19 is fixed to a support member 20 for fixing the receiving blade of the second cutting device 10. The guide cover 16 is changed by the hinge 18 into a working posture for laterally feeding the stock root portion (a state shown by a solid line in FIG. 1) and a storage posture swinging backward (a state shown by a phantom line in FIG. 1). It is configured to be maintainable. In other words, the guide cover 16 is set to the working posture when it is desired to drop the stock base portion from the drop hole 17 in the left and right direction onto the field, and the guide cover 16 is set to the retracted posture when it is desired to sow in a state of six rows. is there.

[Alternative Embodiment] In the above embodiment, by swinging and moving the guide cover 16, it is possible to selectively use the form of collecting the stock root portion by the traversing device 12 and the type of sowing without using the traversing device 12. However, the guide cover 16 may be of a detachable type using bolts or the like, or may have a structure in which the traverse device 12 is entirely detachable.
Further, as shown in FIG. 4, the lateral cutting device 12 of the present invention may be applied to the mowing unit 1 in which the second cutting device 10 has a rotary blade structure.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the attached drawings.
