Description

[Detailed Description of the Invention] This invention relates to an improvement in the structure for attaching grass dividing plates to harvesting machines such as combine harvesters, binders, and reapers.

The above-mentioned harvester is configured to guide the planting stem culm by a weed splitting body attached to the front end of the weed cutting frame in the advancing direction of the reaping conveyance section. The harvesting machine used the structure shown in Figure 5.

In other words, the mounting shaft a extending from the weeding body is configured with a diameter that fits in sliding contact with the inner diameter of the weeding frame pipe b, and the mounting shaft a inserted from the end of the weeding frame pipe is pulled out with a push bolt c. It was designed to be fixed so that it would not come off.

However, with this conventional structure, if the split frame pipe deforms due to contact with an obstacle, it becomes difficult to insert and remove the mounting shaft.
In extreme cases, the problem occurred that it became impossible to insert and remove the grass at all, and it was inconvenient to adjust the position and attach/detach the grass.

The purpose of this invention is to provide a grass divider board mounting structure that does not have the above-mentioned problems.
A pipe with an inner diameter large enough to create an appropriate gap with respect to the outer diameter of the mounting shaft on the side of the grass dividing plate inserted therein is formed, and the diameter of the supporting pipe is reduced by drawing an appropriate range at both ends of the support pipe. The present invention is characterized in that the mounting shaft is slidably held in both reduced diameter portions.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

Figure 1 is a side view showing the case where the present invention is implemented in the reaping conveyance section of a combine harvester, which is one of the harvesting machines.
The illustrated combine harvester has a reaping conveyance section 1 disposed at the front of the machine body, and necessary devices such as a threshing section 2, a control section 3, an engine (not shown), etc. are disposed on the machine body, and is constructed in the same manner as known ones. Ru.

The reaping conveyance unit 1 moves from a drive case 5 that is raised and lowered by the operation of a hydraulic cylinder 4 to a base frame formed by extending a plurality of weeding frames 6 forward, and a stem culm lifting device 7 and a cutting blade device 8. , a cut culm conveying device 9, etc. are arranged.

Furthermore, a grass dividing plate 10 for dividing and guiding the planted stem culms is detachably attached to the tip of each grass dividing frame 6, and the mounting structure of this grass dividing plate 10 is as follows in the present invention. Eggplant.

The grass divider board 10 has a shape that is inclined to a rear height in a side view and widens rearward in a plan view, and has a mounting shaft 11 extending rearward from the back surface thereof.

On the other hand, at the tip of the grass divider frame 6, a grass divider support pipe 12 made of a pipe material having an inner diameter that creates an appropriate gap with respect to the outer diameter of the mounting shaft 11 is fixed by an appropriate fixing means 13. do.

Appropriate range portions L at both ends of the grass divider support pipe 12 are narrowed to form reduced diameter portions 14 so as to have an inner diameter that matches the outer diameter of the mounting shaft 11.

Moreover, in the part between both the reduced diameter parts 14, 14,
Support tool 1 installed outside the grass divider support pipe 12
A locking tool 16 supported by 5 is installed.

The locking tool 16 is attached to the support tool 1 so that it can move forward and backward in a direction perpendicular to the axis of the grass support pipe 12.
5 so that the distal end portion 17 protrudes inward of the support pipe and can be engaged with and disengaged from the locking hole 18 of the mounting shaft 11.
A spring 19 interposed between the locking member and the locking member is biased in the locking direction.

Therefore, when attaching the grass dividing board 10 to the grass dividing frame 6, the locking tool 16 is pulled up against the elastic force of the spring 19, and the tip portion 17 is moved away from the locking position, and the support pipe is 12, the mounting shaft 11 will be attached to the reduced diameter section 1.
4 and 14, it will move and be fitted while slidingly contacting the support pipe 12, and once it is at the predetermined mounting position, the end portion 17 of the locking tool will be attached to the mounting shaft 11.
The grass divider plate 10 is engaged with the locking hole 18 to fix the position.
can be installed in the desired condition.

In addition, if it is necessary to adjust the front and back position of the attached grass dividing board 10 or to remove it, the fixing by the locking tool 16 can be released and the grass dividing board 10 can be moved. Reduced diameter portion 14,1
Since it is carried out only by contacting at 4, it is light and easy to move.

In short, in the grass dividing board mounting structure of the present invention, the mounting shaft 11 of the grass dividing board is connected to the reduced diameter portions 1 at both ends of the support pipe.
Since it is slidably supported only by 4 and 14, the mounting shaft 11
Even if the axial center of the support pipe 12 does not coincide with the axial center of the support pipe 12, it can be inserted and removed relatively easily, and there are fewer places where rust or dirt can get stuck, which is even more advantageous.

In addition, since the structure is such that a support pipe with reduced diameter portions at both ends is fixed to the weeding frame, the weeding frame does not necessarily need to be made of pipe material.
It can be made of any other material.
