Description

[Detailed description of the invention] This invention is a combine harvester, in particular, a reaping device is provided at the front of the machine, a threshing device is provided at the top, and a presser body extends from the reaping device side to the threshing device side.
This invention relates to a combine harvester that presses the tips of grain culms that are conveyed and supplied from a reaping device to a threshing device.

Generally, in the case of this type of combine harvester, it is necessary to manually feed the uncut grain culm or the grain culm from the headland mowing performed when the combine is brought into the field into the threshing device to perform the threshing process, so-called cutting corners.

However, when cutting corners like this, since the presser body is interposed between the threshing device and the reaping device, the presser body gets in the way and makes it difficult to feed grain culms to the grain culm supply port of the threshing device. be.

The present invention was devised in view of the above-mentioned points, and when cutting grain culms, the presser body is swung away from the grain culm holding position so that the grain culms can be easily guided to the grain culm supply port of the threshing device. This is what I did.

More specifically, an end of the presser body on the reaping device side is pivotally connected to a stationary member of the reaping device, and the presser body is operatively connected to a reaping clutch of the reaping device, so that the reaping clutch is The presser body is configured to swing and retreat from the grain culm tip pressing position to a position where the tip of the presser body is along the guide plate or to a position above the grain culm supply port as the grain culm tip is moved from the input to the cut operation. It is characterized by:

The present invention will be explained below with reference to embodiments shown in the drawings.

In the figure, reference numeral 1 designates the body of a combine harvester, which is equipped with a traveling device 2 at the bottom, a reaping device 6 consisting of a grass dividing plate 3, a grain culm lifting frame 4, a cutting blade 5, etc. at the front, and a cutting device 6 consisting of a grass dividing plate 3, a grain culm pulling frame 4, and a cutting blade 5, etc., at the top of the body 1. is equipped with a threshing device 10 which has a grain supply port 7 on the front side, a guide plate 8 extending integrally below the supply port 7, and a grain transport chain 9 on the side. On the other hand, the reaping device 6
A vertical conveying device 11 is interposed between the grain culm harvested by the reaping device 6 and the threshing device 10 to convey and supply it to the conveying chain 9 of the threshing device 10.

Further, at the upper intermediate portion between the reaping device 6 and the threshing device 10, at a location corresponding to the tip of the grain culm lifted by the vertical conveyance device 11, a device is provided to press the tip of the grain and supply it to the supply port 7. A presser body 12 is provided.

Reference numeral 13 denotes a pilot's seat provided on the side of the reaping device 6 in the upper part of the machine body 1. A control box 14 is provided in the front of the pilot's seat 13, and the reaping clutch of the reaping device 6 is mounted on the box 14. A clutch lever 15 for operating the side clutch and other clutch levers 16 are provided upright.

However, in the present invention, in the combine harvester as described above, the end of the presser body 12 on the reaping device 6 side is
The reaping device 6 is pivotally connected to a stationary member such as the grain culm lifting frame 4 through a pivot pin 17, and the presser body 12 is connected to the reaping clutch lever 1.
5 through a link or wire 18, and when the lever 15 is swung forward and upward to hold the reaping device 6 in the operating state, the presser body 12 is conveyed by the vertical conveyance device 11. The tip of the grain culm is held at a position slightly above the grain culm supply port 7 of the threshing device 10, and the presser body 12 is used to hold the tip of the grain culm at the grain culm supply port of the threshing device 10. 7, and when the clutch lever 15 is swung rearward and downward from the above state to bring the reaping device 6 into a stopped state, the presser body 12 is moved rearward and downward around the pivot pin 17. By swinging the presser body 12, the tip of the presser body 12 is brought into contact with the guide plate 8 provided below the grain culm supply port 7, especially at the lower end of the feed port 7. This was done to supply grain culms from headland cutting to the supply port 7.

In the above embodiment, when the reaping clutch lever 15 is swung rearward and downward to stop the reaping device 6, the presser body 12 is swung rearward and downward so as to come into contact with the guide plate 8, The presser body 12 was intended to be actively used as a guide for the grain culm when cutting corners, but in the present invention, when the clutch lever 15 is operated to stop the reaping device 6, the presser body is activated in conjunction with the lever 15. 12 swings back forward and upward from the holding position of the grain culm tip to open the grain culm supply port 7 portion of the threshing device 10, and supply the grain culm to the supply port 7 from this open portion. You can.

The present invention has the above-described structure. When harvesting and threshing grain culms using a combine harvester, the reaping clutch lever 15 is swung forward and upward as shown by the solid line in FIG. Activate. Then, the tip of the presser body 12 is positioned slightly above the grain supply port 7 in the threshing device 10 as shown by the solid line in the figure, and the grain culm that is harvested by the reaping device 6 and lifted by the vertical conveyance device 11 is removed. The tip of the head is held down by the presser body 12 and guided to the supply port 7.

In addition, when cutting grain culms by mowing a headland or the like, with the threshing device 10 in operation, the reaping clutch lever 15 is swung rearward and downward as shown by the imaginary line in FIG. Stop 6. Then, as the lever 15 is operated, the presser body 12 swings backward and downward so that its tip comes into contact with the guide plate 8, and the grain culm is moved from the presser body 12 to the guide plate 8. Then, it is guided to the grain culm supply port 7.

As explained above, in the combine harvester of the present invention, the presser body for the tip of the grain culm is interlocked and connected to the reaping clutch lever, and when the reaping device is stopped by the lever, the presser body is moved from the position for pressing the tip of the grain culm. Since the tip of the body is designed to be swung and retracted to a position along the guide plate or to a position above the grain culm supply port, when cutting grain culms etc. by headland mowing, the presser body can move the grain culms without getting in the way. It became possible to easily supply the grain to the grain supply port of the threshing device, making it easier to cut corners.
