DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pre-treating apparatus for a combine, and can be used for an all-culm-in-type ordinary combine which supplies all of the cut culms to a threshing machine.

[0002]

2. Description of the Related Art A conventional whole-culm-type combine having a structure in which a pretreatment device for a self-removable combine, such as that disclosed in Japanese Patent Application Laid-Open No. 1-26312, is disclosed. The structure is such that the grain stalk raising device used for the mold combine is replaced with a scraping reel and attached.

According to this configuration, the grain stalk raising device is firmly attached by a separate special attaching means,
The clipper-type first mowing device is also attached to the fuselage in an integrated manner. Therefore, each of these devices can be moved up and down only when the entire cutting pretreatment device is moved up and down by a hydraulic cylinder.

[0004]

When a grain stalk raising device and a reaping device used for a self-removing type combine are mounted on the front side of a conventional pre-cutting device for reaping a combine, the mounting means should be as simple as possible. It is required that they can be adjusted up and down and back and forth with respect to the pre-cutting device.

Accordingly, the present invention is to remove the raking reels and weeding rods of the pre-cutting device for ordinary combine harvesters and to attach the culm raising device and the cutting device using the attachment device. . The grain stalk raising device and the mowing device can adjust the angle separately from the adjustment of the pre-cutting device by using means for adjusting the raking reel.

[0006]

The present invention employs the following technical means in order to solve the problems in the combine work as described above. That is, a whole culm throwing type threshing machine is mounted on a chassis having a traveling device with a grain culm supply port in front, and a transport conveyor connected to a scraping auger is provided at the front of the threshing machine so as to be freely movable up and down. A first cutting blade device is arranged on the front side of the scraping auger, and a reel supporting rod provided freely above and below is provided, and the reel supporting rod has a grain stem raising device, A first hydraulic cylinder connected to the reel supporting rod, provided with a cutting pre-processing device for self-combining combine in which a weeding rod and a second cutting blade device are integrally framed;
The cutting pretreatment device should be adjusted up and down by
And a second hydraulic cylinder connected to the reel support rod.
The tilt angle of the cereal stem raising device is adjusted as the
Pre-processing equipment in the combine that is configured to save
There is .

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the configuration will be described. The whole-culm throwing-type threshing machine 4 is mounted on a chassis 1 having a traveling device 1 composed of a crawler with the grain culm supply port 3 facing forward. Then, the threshing machine 4 is configured to supply all of the harvested grain culms (all culms throw-in type) and thresh using the spiral-type handling drum 13.

[0008] The conveyor 6 has a front end which is scraped.
Face the gar 5 and let the end part communicate with the grain culm supply port 3,
It is configured to be able to move up and down freely by a hydraulic cylinder-14. Reference numeral 7 denotes a reaper. The reel support rods 8 are located on the left and right sides above the scraping auger 5 and are provided with a hydraulic cylinder-1.
5 makes it freely up and down. The reel support rod 8 is configured so that a scraper reel (not shown) can be attached thereto.

The pre-cutting device 12 comprises a weeding rod 10 and a second
The cutting blade unit 11 and the raising unit 9 with the raising lugs 16 are integrally framed so that the upper part is on the reel support rod 8 and the lower part is on the front part of the first cutting blade unit 7, respectively. Installed. And, the pre-cutting device 12 is the first
Up and down adjustment can be performed via the reel support rod 8 in accordance with the expansion and contraction operation of the hydraulic cylinder 15 of the second adjustment cylinder 17.
Thereby, the inclination angle of the grain stem raising device 9 and the second cutting blade device 11 can be adjusted.

Reference numeral 18 denotes a scraping transfer device. As shown in FIG. 3, the transmission path of each part is configured to take out the rotational power from one of the scraping augers 5 and transmit the cereal stem raising device 9 via the auxiliary divider 19, and to transmit the first and the above.
The second cutting blade devices 7 and 11 are configured to be transmitted by the crank rod 20 from the other side.

Next, the operation will be described. First,
In the case of performing combine work, when the rotating parts of the machine body are advanced while being driven, the culm of the field is first raised from the stock plant while the base is being weeded by the weeding body 10, and the rug 1 is raised.
6 causes a triggering action. The upper part of the grain stem is cut by the first cutting blade device 7 in the process of being harvested by the second cutting blade device 11 and transported backward while being held by the upper scraping transport device 18. Reaped.

In this manner, the cereal stem is supplied to the first cutting blade device 1.
When the mowing is performed by the cutter 1, the cutter reaches the rear auger 5 and is sequentially sent to the central portion, reaches the transport conveyor 6, and is supplied to the upper threshing machine 4. Then, the grain culm is threshed by the spiral-type handling cylinder 13. Next, when adjusting the inclination angle of the grain stalk raising device 9 according to the degree of lodging of the grain stalk in the field, the second hydraulic cylinder 17 is adjusted.

In other words, the grain stalk raising device 9 can extend the second hydraulic cylinder 17 to a state close to an upright position when the grain stalk in the field is largely laid down, and can perform a proper raising operation. . Further, in the case of reducing the grain稈量supplied to thresher 4 decompresses the first hydraulic cylinder 14 to raise the first cutting blade 7, the opposite case, the <br/> The work may be performed by contracting the hydraulic cylinder 14 and lowering the second cutting blade device 11 through the reel support rod 8 and the grain stem raising device 9.

[0014]

As described above, according to the combine pre-treatment apparatus of the present invention, a stalk reel supporting rod is used to attach a grain stem raising device for a self-removable combine to an ordinary combine. And can be mounted relatively easily. Further, according to this configuration, the reel support rod is
The first and second hydraulic cylinders can be used to provide a specific effect that the height and the inclination angle of the grain stem raising device and the second cutting blade device can be freely selected.
