JPH04252111A - Grass-dividing and guiding device in combine - Google Patents

Abstract

PURPOSE:To smoothly and surely introduce and guide grain straws from grass- dividing points into a raking auger, by installing grass-dividing devices on both the sides of a reaper in a specific state. CONSTITUTION:Grass-dividing devices 3 are installed on both the sides of a reaper 2 so that the tips of the dividers 3 are placed outside the reaping width of the reaper 2 in a tilted shape. The inner guide plates 7 of the grass-dividing devices are extended to places near the sides of a rear raking auger 6 to introduce and guide grain straws into the raking auger.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a divider internal device for a combine harvester, and is applied to a general-purpose combine harvester of the all-culm input type.

0002

[Prior Art] In conventional combine harvesters of this type, the guide plate for guiding the harvested grain culm to the raking auger is constructed separately and attached to the weeding device. Ta. Therefore, the guide plate required a lot of workmanship and had the disadvantage that it was not possible to smoothly guide the grain culm.

0003

[Problem to be solved by the invention] Ideally, the weeding device and grain culm guidance device of this type of combine harvester should cut while guiding the grain culm before reaping, and guide it directly to the raking auger. It is true. However, in reality, the weed culling device and the grain culm guiding device are made and installed separately, which not only requires a lot of work, but also causes the defect that the series of grain culm guidance lacks smoothness. be.

The present invention seeks to eliminate this defect.

[0005]

[Means for Solving the Problems] The present invention employs the following technical means to achieve the above object. On both left and right sides of a reaping device 2 installed below the raking reel 1, there is provided a weeding device 3 whose tip portion protrudes forward. A raking auger 6 for raking and conveying is provided at the supply port, and the tip of the weeding device 3 is configured to have an inclined shape that allows the grain culm to be guided from outside the cutting width. This is an internal device for a combine harvester in which a guide plate 7 is extended to a position where the harvested grain culm can be guided to the scraping auger 6.

[0006]

[Embodiment] First, the configuration will be explained. The pre-processing device 8 includes a scraping reel 1, a reaping device 2, a scraping auger 3, and a conveyor 4, and is attached to the front part of the chassis 9 so as to be freely movable up and down. To be more specific, the raking reel 1 is rotatably supported by a bearing on a support arm 10, and is configured to be able to rak in grain culms. The reaping device 2 adopts a reciprocating type and is configured to be able to mow over a wide range.

The raking auger 3 has a lateral feed spiral and a raking rod, and collects the harvested grain culm at a predetermined portion in the width direction of the pretreatment device 8, and transfers it from the supply port 5 to the rear conveyor 4. The structure is such that it can be scraped and fed. And the conveyor 4
The terminal portion communicates with the grain supply port of the threshing room.

The weeding device 3 is located on both sides of the reaping device 2 and extends forward, and the weeding device 3 extends forward while weeding the grain culms in the field.
It is structured so that it can guide you. Moreover, the weeding device 3 is
The tip part is positioned outside the cutting width of the reaping device 2, so that it can be guided widely. And the inner guide plate 7 is
As shown in FIG. 1, the members constituting the weeding device 3 are extended as they are to near the side of the rear raking auger 6.

In the embodiment shown in FIG. 4, the crawler 11
In the front reaping device 2, the fingers 12 at positions corresponding to the width of the crawlers 11 are constructed to be large. Therefore, the operator has the advantage of being able to operate the combine harvester while observing the position of the fingers 12, such as when guiding the combine harvester onto the footboard. Next, its effect will be explained.

Reaping work is started by starting the prime mover and driving each rotating part of the machine body. Then, the grain culms in the field first reach the reaping device 2 under the action of the raking reel 1 rotating above while being divided by the weeding device 3 at the front. Then, the grain culms are harvested at the base, reach the rear scraping auger 6, and are supplied to the conveyor 4 by a spiral cross-feeding action.

During this series of operations, the inner guide plate 7 guides the grain culms in the field before harvesting, and guides the grain culms in the field to the harvesting device 2.
Then, the harvested grain culm is guided to the raking auger 6. Therefore, the grain culm hardly gets caught and is guided very smoothly.

0012

As described above, the device in the divider of a combine harvester according to the present invention not only has a relatively simple structure, but also allows grain culms to be raked or removed starting from the time of shedding. This has the unique effect of being able to guide the guide smoothly and reliably to the position where it reaches the gutter.
