Field of the Invention The present invention relates to a combine for transferring a grain stalk, which has been cut by a cutting unit which is slid in the lateral direction of the machine, to a feed chain of a threshing unit by a vertical transfer device. And a grain culm conveying device. 2. Description of the Related Art Conventionally, a vertical conveying device has been rotated left and right on a side of a receiving end with a feed chain as a fulcrum, so as to follow a left and right slide of the cutting part. . [0003] In the prior art, the vertical transport device needs to be rotatably held not only up and down but also to the right and left. There was a problem that the transfer performance was inferior to that of a combined grain culm transfer device in which the transfer device and the threshing unit could not maintain a constant relative positional relationship with the feed chain, and the cutting unit did not slide left and right. SUMMARY OF THE INVENTION It is an object of the present invention to combine a grain of a combine that can transfer a culm from a cutting unit that slides left and right to a feed chain of a threshing unit without moving the vertical conveyance device to follow the left and right slide of the cutting unit. It is an object of the present invention to provide a culm conveying device and eliminate all conventional problems. [0005] Accordingly, the present invention provides an airframe

It is formed parallel, that is, parallel to the feed chain (5). The grain transfer surface (26a) on the feed start end side of the vertical transport chain (26) and the grain transfer surface (27a) on the feed start end side of the vertical transport tine (27) are connected to the slide shaft of the cutting unit (7). The right and left culm transport chains (24) and (22) and the right and left spike transport tines (25) and (23) are substantially parallel to the axis (L) of the slide pipe (40), which is the core, that is, the right and left culm transport chains (24) and (22) associated with the left and right sliding of the cutting unit (7). ) Is formed in a straight line along the moving direction of the feed end, and the length is substantially the same as the entire slide stroke of the mowing part (7), that is, the right and left culm base transport chains (24) (22) accompanying the right and left sliding of the mowing part (7). ) And the left and right spike transport tines (25) and (23) are formed to have a length substantially equal to the moving distance of the feed end, and when the cutting unit (7) is moved to the right slide end position, three rows of grain stalks The culm base is transported as shown by the solid line in Fig. 1. From the feed end side of the chain (24) (22) to the vertical transfer chain (26) on the right side of the grain culm transfer surface (26a) on the feed start end side. 23) The spike tip side of the grain culm is inherited from the feed end side of the vertical transport tine (27) at the feed start end side of the vertical transport tine (27), and the grain stalk inheritance surfaces (26a) (27) are inherited.
In (a), the culm base and the tip side of the cereal culm are once transferred to the left side, and the cereal culm vertical transfer surface (26c) (27c) continuous with the left end of the cereal culm inheritance surface (26a) (27a) is cultivated on the lower end. The culm of the culm is transferred to the grain culm transfer surface (26b) of the feed chain (5) which is continuous with the upper end of the culm by the cereal culm vertical conveyance surface (26c) of the vertical conveyance chain (26). While the culm of the grain culm is transferred from the grain culm receiving surface (26b) to the feed start end of the feed chain (5) parallel to the grain culm receiving surface (26b), while the cutting unit (7) is moved to the left slide end position. When it is moved, the culms of the grain culm for three rows are moved from the feed end side of the left and right culm base transfer chains (24) and (22) shown by the imaginary line in FIG. 1 to the feed start end side of the vertical transfer chain (26). Directly at the left end of the grain culm transfer surface (26a), that is, the lower end of the grain culm vertical transfer surface (26c). When the left and right tip transport Tyne (2
5) The vertical transport chain (26) and the vertical transport tines are inherited from the feed end side of (23) by inheriting the spike tip side of the grain culm at the grain culm receiving surface (27a) at the feed start end side of the vertical transport tine (27). The feed chain (5) is moved from the grain culm receiving surface (26b) on the feed end side of the vertical transport chain (26) parallel to the feed chain (5) without moving (27) following the left and right slide of the mowing unit (7). ), The culm of the grain culm is inherited and conveyed to the feed start end side, and the vertical conveying chain (26) and the vertical conveying tine (27), the left and right culm original conveying chains (24) (22), and the left and right spike conveying tine (25) It is configured such that the front and rear positional relationship with (23) is kept constant, and the grain culm is inherited and conveyed between them. [0021] As apparent from the above embodiment the present invention is threshing section from reaper sliding to the machine body transverse direction (7) (4) culms conveying apparatus combine for conveying the culms into In the above, the vertical transport devices (26) and (27) for transferring the harvested grain culm to the feed chain (5) of the threshing unit (4) while adjusting the handling depth are interlocked with the left and right slide of the harvesting unit (7). The vertical transport device (26) (2
7) The front transport device (22) (23) (24) (2)
5) is made movable left and right in conjunction with the left and right sliding of the mowing part (7), and a grain culm inheriting part from the front conveying devices (22) (23) (24) (25) of the vertical conveying devices (26) and (27). To the front transport device (2) associated with the left and right sliding of the mowing unit (7).
2) A vertical transport device for the right and left slides of the cutting unit (7), which is formed in a linear portion (26a) (27a) along the moving direction of the feed end of (23), (24) and (25). (6)
The function of turning the left and right of (27) becomes unnecessary, and the vertical transport device (2)
6) The holding structure of (27) is simplified, and the front transport device (22) (23) (24) (25) of the cutting unit (7).
In addition, the succeeding relative positional relationship between the threshing unit (4) and the feed chain (5) can be maintained optimally in the same manner as a combine grain vertical conveying device in which the cutting unit (7) does not slide left and right, and the conveying function is also possible. It has remarkable effects such as being the best.
