Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a reaping section transmission device in a combine harvester for reaping and threshing culms.

(B) Prior Art Conventionally, a combine harvester that transports the culm scraped by the scraping band of one scraping route laterally at the rear of the scraping belt, and joins the other scraping route at the end of the conveyance has been used in practice. This is already known from Japanese Publication No. 58-37225, etc., and a combine harvester in which the end of one raking path joins the end of another raking path in a V-shape is disclosed in JP Utility Model Publication No. 58-125.80. (c) Problems to be Solved by the Invention In the former known combine harvester, both the starting and ending ends of the traversing section at the rear of the raking band are located at the front of the traversing path. , the end of the cross-feeding section returns to the front at the merging section and rotates, and at that time, the husk culm at the merging section is scraped forward, which disrupts the husk culm and directs the merged husk toward the threshing device. This is because the starting end of the vertical conveying device is located further back than the rear end of any of the scraping bands.

The inheritance of the husk was uneven, resulting in culm leakage and clogging, and this method did not allow the cutting width to be more than 5 rows.

In addition, in the latter case, all of the cut culms are conveyed diagonally backward and merged, so the distance between the reaped part and the merged part becomes large, and if the reaped width is 5 or more rows, additional raking is required. The paths have to merge further back from the above-mentioned merging point, which increases the distance, and as a result, heavy objects such as the weeding body, the pulling body, the raking device, and the cutting blade protrude significantly toward the front of the machine base. So, 41! When the body vibrates, the grass cuttings and the like may fall into the soil.

(d) Means for solving the problem The present invention drives the scraping bodies of the plurality of scraping paths attached to the transmission system provided at the front part of the horizontal conveyance path by separate transmission cases, and The culm scraped from the route is collected on a horizontal conveyor and transported horizontally, thereby shortening the longitudinal length of the culm scraping route.
By driving the raking body of the raking path on the uncut land side, the conveyance belt of the horizontal conveyance path, and the following vertical conveyance body by the transmission system at the rear of the horizontal conveyance path, the raking body from the raking path on the uncut land side is driven. The above-mentioned problems have been solved by making it possible to combine grains and culms and transfer them to the vertical conveyance device in an orderly manner without spilling the culms or causing any disturbance.

(e) Effect: The multi-row cut culm is raked from a plurality of raking paths into a series of traversing paths and merges, and the raking zone at the end of the lateral conveying body and the uncut land side of the raking paths is It can extend to the rear transmission system, and the culms scraped from the uncut land side can be smoothly merged towards the rear, and this merged culm can be connected to the same rear transmission system as the lateral conveyor mentioned above. Since the culm is driven by the culm, it is possible to transfer the merged culms to the vertical conveyance device in an orderly manner without clogging or leakage.
