Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mowing frame structure for a multi-row combine harvester.

[0002]

2. Description of the Related Art Generally, a cutting frame for a multi-row combine harvester comprises a plurality of weeding pipes for supporting a stem-causing and a case and an intermediate pipe arranged between these weeding pipes. The vegetation pipe is configured to extend forward from the frame base mounted on the machine frame of the combine so as to form a stem-culm introduction path between the adjacent hay pipe and the intermediate hay pipe. In the conventional cutting frame, the weeding pipe and the intermediate weeding pipe are all welded to the frame substrate to be integrally framed.

[0003]

Since the conventional mowing frame is constructed as described above, it is convenient for cutting the planting stem culms for row planting, but it is convenient to cut the planting stem culms for rose planting. When mowing, there is a problem that the intermediate buds that do not support the culm-causing case will step on the planted culms that have been planted in roses, and the stems will not be introduced and transferred in a neat posture. . Moreover, the stalk-raising case supporting the stalk-causing case is strong against external force because it is in a framework state due to its support, but the intermediate sprouting pipe supports the stalk-causing case. However, since it is simply extended forward from the frame base body, deformation or the like is likely to occur due to an external force, but there is also a problem that the repair is not easy.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is not only when cutting planting stem culms for row planting but also when sowing in roses. The cutting frame of a multi-row cutting combine that allows the planting stalks to be introduced and transferred well even when cutting the planting stalks in a state of being cut, and that the intermediate buds can be easily repaired. To provide.

In order to achieve the above object, the cutting frame structure for a multiple-strip combine of the present invention has a plurality of weeding pipes for laterally connecting a plurality of weeding pipes for supporting and supporting stem stems at the front end thereof. -In a cutting frame of a multi-row cutting combine, which is fixed in parallel to a frame base body at a predetermined interval, and an intermediate grass pipe is arranged between these grass pipes, the intermediate grass plant The pipe is detachably attached to the frame base.

Then, in order to detachably attach the intermediate grass pipe to the frame base body, a pair of left and right mounting plates are provided on the side of the intermediate grass pipe, and the mounting plates are inserted into the supporting seats on the frame base body side. It is structured such that it is tightened and fixed with a fastener, and the lower surface of the regulation body fixed to the mounting plate abuts the upper end surface of the side wall of the support seat to prevent the intermediate hay pipe from moving in the vertical direction in the mounted state. Is preferred.

In addition, the intermediate sward pipe is attached to the frame base body by providing a concave support plate on the upper surface of the support seat on the frame base body side while inserting the vertically oriented fastener on the intermediate sward pipe side. The tube is installed through, the intermediate bushing pipe is supported by the concave receiving plate,
The intermediate penetrating pipe may be attached to the frame base by screwing a bolt inserted into the fastener insertion tube into a nut fixed to the lower surface of the concave receiving plate and tightening the nut.

[0008]

[Operation] When cutting and harvesting the stem culms for row planting, an intermediate bud pipe is installed between the bud stems that raise the stalks and supports the case, and the adjacent bud pipes are connected to each other. Rows of planted stem culms are introduced into the stem culm introduction paths formed between the intermediate buds and the pipes, respectively, and are transferred to the rear. Further, in the case of cutting and harvesting planted stem culms that are planted in roses, by removing the intermediate weeding pipe and working, it is possible to make a good transition without trampling the rose stalks.

[0009]

In the cutting frame structure according to the first aspect of the present invention, an intermediate bud pipe arranged between a plurality of bud pipes for raising the stem culm and supporting the case is provided at the front end, if necessary. Since it can be attached and detached, when cutting and harvesting rose-sown planting culms, by removing the intermediate weeding pipe, it is possible to introduce and transfer well without stepping on the rose-stalking culms, and, Even if the intermediate bushing pipe is deformed, it can be easily replaced and repaired and maintenance is easy.

In order to detachably attach the intermediate sward pipe to the frame base, a pair of left and right mounting plates are provided on the side of the intermediate shunt pipe, and the mounting plate is attached to the frame.
The insert is inserted into the support seat on the base side of the base and tightened and fixed with fasteners, and in this installed state, the lower surface of the regulator fixed to the mounting plate abuts the upper end surface of the side wall of the support seat, and Or a concave support plate is provided on the upper surface of the support seat on the frame base side, while the vertically oriented fastener is inserted on the intermediate hay pipe side. Insert the tube through the intermediate bushing pipe, and support the intermediate bushing pipe on the concave support plate.Tighten the bolt that penetrates the fastener insertion cylinder into the nut fixed on the lower surface of the concave receiving plate and tighten it. When it is configured to be attached to the frame base,
While the intermediate bushing pipe can be attached securely, the structure is simple and the attachment / detachment is easy.
