ンバインの刈取部に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention is a combine harvester for harvesting planted culms and supplying them to a rear threshing device. Side-by-side pair of main transporting device and tip side of the root side that brings the plant side and the tip side of the grain culms raised in parallel with the raising device to the gathering point in the center or in the vicinity of the cutting width direction The present invention relates to a combine harvester, which is provided with an auxiliary transport device and which is provided with a vertical transport device for transporting the harvested culm collected at the gathering point to the threshing device.

のものとの間で構成部品の兼用化を図り易い。In the harvesting section of such a combine, the pair of left and right main transfer devices and the auxiliary transfer device transfer the three-row grain culms raised by the three raising devices to the gathering point which is the transfer point to the vertical transfer device. Therefore, the conveying system can be simplified as compared with a case where the three grain culms raised by each of the three raising devices are conveyed to the gathering place by different conveying devices. Also,
Since the basic configuration of the two-row mowing type combine provided with two raising devices is the same as that of the entire conveying system, it is easy to use the component parts for the two-row mowing type combine.

−172321号公報）。In the conventional reaper having such an advantage, a rotary packer for feeding the grain culms raised by the central raising device to the main conveying device on the left and right sides is provided as an auxiliary conveying device, and thus the left and right sides and the center are provided. The grain culms raised by the raising device of the above are transported to the gathering place by the main transport device on the left and right sides, and the grain culms raised by the raising device on the other side of the left and right sides by the main transport device on the other side of the left and right sides. It was configured to
-172321).
しかし、前記従来技術によるときは、次のような欠点
があった。However, the above conventional technique has the following drawbacks.

での縦搬送装置への受け渡しにミス等が生じ易かった。In other words, basically, a pair of left and right main conveyors conveys three-row grain culms, so that, for example, as compared with a case in which three main conveyors convey three-row grain culms, the conveyance action is difficult. Easy to remove. As a result, in general, in order to prevent the conveyance performance from being deteriorated in either of the left and right main conveyors, one of the left and right main conveyors should be properly used for the grain culm raised by the left and right one side raising device. Mowing is performed by arranging the pair of left and right main transport devices at the positions where they act. However, even in such a case, the left and right main transport devices are easily displaced from the proper working position with respect to the grain culms raised by the left and right pulling devices, and the left and right main transport devices have stable transport action. In the related art, the posture of the grain culverts conveyed by the other main conveying device on the left and right sides is disturbed, and mistakes and the like are likely to occur in the delivery to the vertical conveying device at the gathering place.
本考案の目的は、上記欠点を解消する点にある。 An object of the present invention is to eliminate the above drawbacks.

点にある。A characteristic configuration of the combine harvester according to the present invention is that three raising devices are arranged side by side, and the root side and the tip side of the grain culm raised by these raising devices are arranged at the center or in the cutting width direction. A pair of left and right main carrier devices on the stocker side that are brought closer to the gathering place and an auxiliary carrier device on the tip side are provided, and a vertical carrying device that carries the harvested culm gathered at the gathering place to the threshing device is provided. A combine harvester, which constitutes the auxiliary transporting device, comprises a rotary packer for preventing forward tilting, which is provided with a transporting protrusion that is elastically retracted and displaces a grain culm raised by the raising device in the center. The rotary packer, which is arranged so as to be fed to the one of the left and right main transport devices and has a rigid transport protrusion, feeds the grain culms raised by the pulling device on the left and right other sides to the other left and right main transport devices. The point is that they are arranged in a state.

搬送装置による搬送を安定化できる。For the grain culms raised by the one-sided raising device, the left and right one-sided raising devices are cut by performing cuttings so that one of the left and right main transport devices is positioned at a position in the left-right direction in which they properly act. It is possible to satisfactorily and surely convey the grain culm raised in step 1 to the gathering place by the left and right main conveying devices. Moreover, since a rotary packer for preventing forward tilting is provided to prevent the grain stems raised by the central raising device from falling forward and separating from the main transport device, the central raising device is used. It is possible to reliably and satisfactorily convey the grain culm raised by the central raising device, regardless of having no dedicated conveying device for conveying the raised grain culm. In addition, with a rigid conveying protrusion, that is, by providing a rotary packer with a strong conveying ability, the grain culm raised by the raising device on the other side of the left and right sides is sent to the other main conveying device on the left and right sides. Therefore, in order to ensure the transport action by the left and right main transport devices as described above, one of the left and right main transport devices is positioned at the proper working position with respect to the grain culm raised by the left and right raising device. By doing so, the main transport device on the other side of right and left is not located at the proper operating position with respect to the culms raised by the raising devices on the other side of the left and right sides, and Even when the transport performance of the other main transport device on the left and right sides is slightly degraded, the transport degradation by the feed by the rotary packer can be compensated for, and the transport by the other main transport device on the left and right can be stabilized.

実、良好に行なうことができるようになった。Therefore, according to the present invention, while adopting a simple structure in which only two left and right units are provided as the main transporting device for transporting the three grain culms raised by each of the three raising devices to the gathering point, It became possible to reliably and satisfactorily convey each of the three-row grain culms to the gathering position without disturbing the posture and to reliably and satisfactorily transfer the grain culms to the vertical transport device.
