Description

[Detailed description of the invention] The present invention mainly includes an inclined waste straw conveying device that is attached to the threshing section of a combine harvester and conveys the waste straw diagonally after threshing, a waste straw cutter that shreds the waste straw, and a waste straw cutter that shreds the waste straw. The present invention relates to a waste straw processing device which is comprised of other waste straw processing devices such as a waste straw dropper that discharges a certain amount of long straw into a field.

This waste straw processing device switches the conveyance path of the waste straw conveying device to a state in which the waste straw is guided to the waste straw cutter and a state in which it is guided to the waste straw dropper. If there is a large error in the relative positional relationship of the side paths, clogging of the waste straw will occur at this switching point, so it is necessary to accurately determine the relative positions of the waste straw transport device, the waste straw cutter, and the waste straw dropper. .

However, in the past, the inclined waste straw conveying device and the waste straw cutter were separately attached to the machine body, and each
It must be installed in the correct position relative to the aircraft, and
Models that require a special straw dropper to be installed require even more precision during installation, and are troublesome as they require machining of the location and work that requires nerves.

The present invention aims to solve this problem.

The technical means taken by the present invention is that the waste straw processing device and the waste straw conveying device are integrally connected to the waste straw cutter,
This integrated structure is constructed so that it can be attached to, detached from, and interlocked with the threshing device, resulting in the following effects.

According to the present invention, it is possible to predetermine and assemble the inclined waste straw conveying device and the waste straw cutter whose relative positions must be determined accurately, so that each component of the waste straw processing device called the path switching device can be assembled in advance. Although it includes a structure that requires accurate relative positioning between the threshing parts, it can be installed in the correct position and is easier to install than other types of threshing parts. It's possible.

That is, the removed straw cutter, the removed straw conveying device, and the removed straw processing device are very bulky as a whole, and in particular, because the removed straw conveying device is tilted, the overall bulk of the removed straw conveying device is larger than that of the removed straw conveying device. It is more bulky than a type in which a so-called cutter and a waste straw processing device are arranged in series along the direction of movement of the machine.

However, since the present invention has an inclined waste straw conveying device and has three parts integrated as mentioned above, it is easy to attach and detach it to the threshing device even though it is bulky as mentioned above. The present invention, which has advantages and advantages, has not existed heretofore.

In particular, since the waste straw processing device according to the present invention is integrated and is constructed as a whole to be detachably attached to the threshing device, it is easy to test the operating status of this device part. Also, because it is a one-piece product, it can be installed accurately regardless of whether it is attached to or removed from the threshing device as mentioned above.
The removal of the thresher from the threshing equipment for inspection and other work can be done while all the equipment is in series, making it possible to work more efficiently. Since the invented device can be removed as a single unit, it has the advantage that both the main body of the combine and the detached waste straw processing device can be easily stored in a compact storage space.

Furthermore, if an arrangement is adopted in which the transfer direction of the waste straw conveying device is inclined in order to discharge the long straw to the cut field side when the long straw is discharged, the switching tool can be removed from the series of husk conveyance paths of the threshing device 5. The conveyance direction of the waste straw that reaches this waste straw conveyor through the transfer section is changed, and it is also sent to the waste straw conveyor through the joint, so it is difficult to set the relative positions of each device and parts. However, as mentioned above, in this invention, an inclined waste straw conveying device and a waste straw processing device are integrally connected to the waste straw cutter, and this integrally connected device can be attached and detached from the threshing device. In addition, by being able to interlock freely, even if the conveying direction is changed or there is a joint, the straw removal posture will not be disturbed significantly beyond the range expected in the design. The straw discharged from the threshing device can be discharged to the mown field in a well-organized manner, and the straw can be properly disposed of, which is different from the conventional structure in this respect. It has significant advantages over other countries.

Embodiments of the configuration of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall side view of a combine harvester equipped with a waste straw processing device 1, in which planted culms are pulled up with a lifting device 2, harvested with a reaping device 3, and transported to the rear of the machine with a rear conveyance device 4. Delivered to the feed chain 6 of the installed thresher 5,
The waste straw processing device 1 is configured to process threshed waste straw.

The waste straw processing device 1 is composed of a waste straw conveying device 7, a waste straw cutter 8, and a waste straw dropper (device for waste straw processing) 9. Specifically, the waste straw cutter 8 is suspended horizontally, and the waste straw cutter 8 is suspended horizontally. The casing 10 has an opening 11 for introducing long straw in its upper part, and one end of a U-shaped culm 12 and 12 in which a stock passage is formed is fixed to the casing 10, and a chain of the straw removal conveying device 7 is fixed to the casing 10. A sprocket 14 on which a sprocket 13 is wound and a support frame 16 on which an idler wheel 15 is supported are fixed to the free ends of the U-shaped culms 12, 12, and the waste straw conveying device 7 is attached to the waste straw cutter 8.
