ンバインの茎稈搬送機構に関する。[Detailed Description of the Invention] The present invention has a stock base that can be freely oscillated relative to the rear conveyance mechanism with the starting end as the center, below the rear conveyance mechanism that feeds the stem culms from the reaping section to the threshing device. A combine harvester, comprising: a clamping conveyance device; and a handling depth adjustment mechanism capable of changing the holding position of the conveyed stem culm in the rear conveyance mechanism from a starting end to a terminal end of the rear conveyance mechanism. This invention relates to a stem culm transport mechanism.

た。In the stem culm conveyance mechanism of the above-mentioned combine harvester, a mechanism for adjusting the handling depth has conventionally been installed below the rear conveyance mechanism in the culm length direction of the conveyed stem culms, as shown in Japanese Utility Model Application Publication No. 48-17327. It has been known to have a stock head clamping and conveying device that swings and displaces the stock head in the vertical direction, but when such a mechanism is used, there is a space below the stock head clamping and conveying device for the swinging displacement. This requires a large moving space and a space for arranging a swinging displacement device, which limits how the space below the stock clamping and conveying device can be used.

。Therefore, it was considered to use a device known from Japanese Utility Model Application Publication No. 49-127330, which adjusts the handling depth by oscillating the stock head clamping and conveying device in the lateral direction below the ear tip conveying device. - The handling depth adjustment mechanism by this device is such that the posture of the conveyed stem culm is made oblique by the gripping conveyance device which is oscillated in the horizontal direction, and the straight line distance between it and the upper tip conveyance device is lengthened. It is a device that adjusts the depth.If you try to increase the handling depth by increasing the straight line distance, the gripping and conveying device must be further oscillated in the direction of lateral force. Due to the large change in the posture of the stem culm being transported by the clamping and conveying device, the transfer of the conveyed stalk culm to the feed chain of the threshing device may not be carried out smoothly enough, and the clamping and conveying device may protrude too far from the side of the machine, making it difficult to carry out work. Up.
不都合が生じる虞れがあるものであった。There was a risk that this would cause some inconvenience.

の茎稈搬送機構を提供することを目的とする。The present invention solves these problems, expands the utilization of the space below the rear conveyance device, and allows the transfer of the conveyor culms to the feed chain of the threshing device to be carried accurately and reliably, with a small amount of rocking displacement. The purpose of the present invention is to provide a stem culm conveying mechanism for a combine harvester that can sufficiently adjust the handling quality by changing the amount of chestnuts handled.

。In the stem culm conveyance mechanism of the combine harvester described above, the present invention comprises one rear conveyance mechanism that is vertically overlaid with a head locking rear conveyance device and a stock head rear conveyance device, and also includes a swinging motion of the stock head clamping conveyance device. The displacement direction is configured to be freely displaceable in the lateral direction, so that the starting end of the stock head rear conveyance device and the starting end of the stock head clamping and conveying device are arranged so that the starting end of the stock head rear conveying device and the starting end of the stock head clamping and conveying device are aligned as viewed in the direction of the swing center axis of the stock head holding and conveying device. It is characterized by overlapping.

の利用度を広めながら。That is, since the stem culm is conveyed by three members: the tip-locking rear conveyance device and the stock head conveyance device which are stacked vertically, and the stock head clamping conveyance device which is oscillated in the lateral direction, the above-mentioned stock head clamping means Due to the lateral rocking displacement of the conveyance device, the upright stem culms are bent laterally between the plant head rear conveyance device and the plant head clamping conveyance device, and the upright stem culms are bent laterally between the plant head rear conveyance device and the plant head clamping conveyance device. The handling depth is adjusted by changing the distance from the device and being pulled out.Rather than changing the linear distance, the handling depth of the stem culm can be adjusted by a small amount of rocking displacement in the lower layer. In addition, since the stock clamping and conveying device is capable of swinging in the lateral direction, the space below it can be utilized more widely.
