In such a seven-row mowing combine, as described above, a plurality of intermediate conveying units are provided in the central portion of the mowing width direction. Patent Document 1 does not describe the transmission structure in detail, but when power is transmitted via a long path while bypassing the space through which the grain stem passes for a plurality of intermediate conveying units, the transmission structure becomes complicated and power loss is reduced. There are disadvantages such as occurring.

Therefore, in the combine of the 7-row mowing type, it has been desired to be able to efficiently transmit power to a plurality of intermediate conveying units located in the central portion in the width direction of the mowing.

A characteristic configuration of the combine according to the present invention is a traveling body having left and right traveling devices, the left and right traveling devices, a mowing unit provided at the front of the traveling body and capable of mowing 7 trillion of planted grains, and the A harvesting support frame for supporting the harvesting portion to the traveling body is provided, and the harvesting portion is provided at an interval in the left and right direction, and a plurality of branching spheres defining seven grain stem introduction paths, and all the grain stem introduction paths 7 grain stem standing devices that are provided corresponding to each of and further stand up the planted grain stems, a mowing device that cuts the grain stems introduced into all the grain stem introduction paths, and the harvested grain stems merge into the harvesting width direction, A conveying device for conveying in the left and right direction is provided, and in the conveying device, one end conveying unit for conveying the harvested grain stems of the two grain stem introduction paths rearwardly located on one side in the left and right direction, and the two grain stems positioned on the other side in the left and right direction The other end-side conveying unit for conveying the harvested grain stem of the introduction path to the rear, the confluence center conveying unit for conveying the harvested grain stem of the two grain stem introduction paths rearwardly located in the middle part in the left and right direction, and the middle part located in the left and right direction A single-stream central conveying unit for conveying the harvested crop of the other grain stem introduction path to the rear is provided, and in a state that passes through the inside of the mowing support frame, the mowing that transmits the power of the engine provided in the traveling body to the mowing unit A transmission shaft is provided, and a central branch transmission mechanism for transmitting the power branched from the harvesting transmission shaft to the single-stream central conveying unit and the converging central conveying unit is provided in the middle of the mowing support frame. .

According to the present invention, the harvested grain stems of the seven grain stem introduction paths are conveyed to the rear by each of the one end side conveyance section, the other end side conveyance section, the merge center conveyance section, and the single stream center conveyance section. A central branch transmission mechanism is provided in the middle of the harvesting support frame for supporting the harvesting portion. In this central branch transmission mechanism, power is branched from the mowing transmission shaft provided inside the mowing support frame, and the branched power is transmitted to the single-stream central conveying unit and the converging central conveying unit.

The mowing support frame is positioned at a location skewed toward the center side in the left and right direction so as not to interfere with the driving unit and the like, and is provided in an inclined posture that is positioned downward toward the front side of the aircraft. The single-stream central conveyance part and the merge central conveyance part are provided in a state which is located at the center side in the left-right direction of the harvesting part, and is located at the upper side of the middle part of the harvesting support frame in an oblique posture. As a result, the single flow center conveyance part and the merge center conveyance part, and the middle part in the mowing support frame are provided at a position close.

Therefore, the power branched from the mowing transmission shaft is transmitted to the single-stream central conveying unit and the converging central conveying unit by the central branch transmission mechanism provided in the middle of the mowing support frame, so that the transmission path is as short as possible efficiently. Can transmit power.

Therefore, in the combine of the 7-row mowing type, it has become possible to efficiently transmit power to a plurality of intermediate conveying units located in the central part of the mowing width direction by using the arrangement configuration of each device.

In the present invention, the central branch transmission mechanism includes a first branch transmission shaft that transmits the power branched from an intermediate portion of the mowing transmission shaft to the single flow central conveyance portion, and from the middle portion of the first branch transmission shaft. It is suitable if a second branch transmission shaft for transmitting the branched power to the converging central conveying unit is provided.

According to this configuration, the power branched from the middle portion of the mowing transmission shaft is transmitted to the single-stream central conveying unit through the first branch transmission shaft. Then, power is branched from the middle portion of the first branch transmission shaft to the second branch transmission shaft, and the branched power is transmitted to the confluence central conveying unit.

Since power is transmitted from the first branch transmission shaft to the single-stream central conveying unit, there is no case of passing through an unnecessary path, and power transmission can be performed efficiently. In addition, the converging central conveying unit having a position different from that of the single-flow central conveying unit is configured to branch from the middle portion of the first branch transmission shaft to the second branch transmission shaft, thereby branching power from the mowing transmission shaft, which is a large member. The structure is complex and does not increase in size, and it becomes possible to fit the central branch transmission mechanism into a compact shape.

In the present invention, in the first branch transmission shaft, power is branched from the mowing transmission shaft through a bevel gear mechanism to extend in an oblique front direction, and to transmit the power to a driving wheel in the single flow central conveying unit. And the power is transmitted from the second branch transmission shaft to a third branch transmission shaft extending obliquely forward from the second branch transmission shaft through a bevel gear mechanism, and the third branch transmission shaft is a driving wheel in the confluence central conveying unit. It is suitable if it is configured to transmit power to the furnace.

According to this configuration, the first branch transmission shaft is provided in a state in which the first branch transmission shaft extends from the middle portion of the mowing support frame toward the oblique front side, and the first branch transmission shaft transmits power to the drive wheel in the single flow central conveying unit. . The mowing support frame is in an inclined posture positioned downwardly toward the front side of the aircraft, and by reasonably arranging the first branch transmission shaft from this mowing support frame through a bevel gear mechanism, it is possible to efficiently transmit power in a short path.

In addition, a third branch transmission shaft extending further obliquely forward from the second branch transmission shaft is provided, and the third branch transmission shaft transmits power to the driving wheel in the converging central conveying unit. By reasonably arranging not only the transmission shaft but also the second branch transmission shaft together, power can be efficiently transmitted to the single-stream central conveying unit and the converging central conveying unit in a short path.

In the present invention, the end of the mowing transmission shaft for transmitting the power branched from a position above the transmission rather than a position provided with the central branch transmission mechanism to at least one of the one end conveyance unit and the other end conveyance unit. It is suitable if a side branch transmission mechanism is provided.

According to this configuration, the power branched from the position above the transmission rather than the position where the central branch transmission mechanism of the mowing transmission shaft is provided is transmitted to at least one of the one end side conveyance unit and the other end side conveyance unit through the end side branch transmission mechanism. .

In this way, the power branched from the mowing transmission shaft can be transmitted to at least one of not only the single-stream central conveying unit and the converging central conveying unit, but also the one-side conveying unit and the other end-side conveying unit. Can be done.

In the present invention, in the conveying device, a scraping rotating body for scraping the root of the harvested grain stem harvested by the harvesting device rearward is provided corresponding to each of the seven grain stem introduction paths, and the central branch The power transmitted to the converging central conveying unit through a transmission mechanism is transmitted to the confluence of the scraping rotary body provided corresponding to the converging central conveying unit, and transmitted to the single flow central conveying unit through the central branch transmission mechanism. Power is transmitted to the single-stream scraping rotor provided corresponding to the single-stream central conveying unit, and the confluence of the scraping rotating body and the single-stream scraping rotating body are interlocked and rotatably fitted. It is suitable if it is provided in a biting state.

According to this configuration, the power transmitted to the confluence central conveyance unit is transmitted to the confluence scraping rotation body provided corresponding to the confluence central conveyance unit. Further, the power transmitted to the single-stream central conveying unit is transmitted to a single-flow scraping rotary body provided corresponding to the single-stream central conveying unit. In addition, the joining scraping rotation body and the single flow scraping rotation body are interlocked and rotatably engaged.

As a result, with respect to the single-stream scraping rotation body, while the power is transmitted from the single-stream central conveying unit, the power is also transmitted by interlocking interlocking through the confluence scraping rotating body from the merging central conveying unit.

By the way, since the power is transmitted from the single-stream central conveying unit, the single-stream scraping rotation body may be configured so as not to mesh with the confluence scraping rotation body. However, the single flow central conveying unit conveys the harvested grain stem of one grain stem introduction path backward, and the volume of the grain stem is smaller than that of the other grain stem introduction path. If such a volume is low, there is a concern that it may become difficult to receive the scraping action when only a single scraping rotation body acts without being meshed with the adjacent scraping rotation body.

Therefore, in this configuration, the single-stream scraping rotor is driven in synchronization with the single-stream central conveying unit, and is interlocked with the confluence scraping rotation body, so that the grain stem conveyance to the rear can be satisfactorily performed. Together with this, it becomes easy to properly exert the scraping action.
