Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an AT conveying device for harvested grain culms of a combine harvester, and can be used in a combine harvester.

2. Description of the Related Art Conventionally, there has been a system in which a grain culm handover guide sheet is provided in the gap between a grain culm inlet of a grain culm inlet of a grain culm handover conveyor and a threshing device, and an elastic plate is provided from below to receive the grain culm.

Problems to be Solved by the Invention Although the shapes of the edges on both sides of the gap between the takeover conveyance device and the inlet of the threshing device are complex and the shapes are not the same, It is desirable to make one end of the guide sheet closely fit and follow the inlet funnel of the threshing device, so if the guide sheet is made flexible, it will not hang down from the gap between the transfer conveyance device and the threshing device and come off the threshing device. there were. Furthermore, if a leaf spring or the like is attached to the back side of the guide sheet to bridge both ends of the gap, only the spring mounting portion becomes stiff, and a gap may be created that does not align with the entrance of the threshing device, causing grains to fall.

Means for Solving the Problems This invention provides a g! At the grain culm transport end portion (6) of the transfer conveyance device (5) that transfers the grain culm harvested in step 1 (3) to the threshing device (4) mounted on the traveling trolley (1), this conveyance terminal is installed. A guide sheet (7) is provided that covers the gap (a) between the part (6) and the threshing device (4) and guides the grain culm to the threshing device (4) with its surface. Mounting part (
Attachment/detachment handle (9) is attached to the pull-j II transfer attachment portion (8) to which the transfer transfer device (5) is detachably attached to 2).
The back force Y of the guide sheet (7) at the gap (a)
This is a structure of a harvested grain culm transfer and conveyance device for a combine harvester, which is provided so as to be able to contact and support the harvested grains.

Functions and Effects of the Invention Grain culms harvested by the reaping device (3) are transferred to the conveyance device (5).
is received and conveyed to be taken over to the threshing device (4), and is guided from the conveyance terminal end (6) to the surface of the guide sheet (7). At the gap (A) between the transfer and conveyance device (5) and the threshing device (4), the attachment/detachment handle (9) of the transfer and conveyance device (5) is attached.
The guide sheet (7) supported by a part of the gap (
The purpose is to safely guide the grain culm to the threshing device (4) without descending from (a).

Since the guide sheet (7) can be supported between the gap (a) by the attachment/detachment handle (9), the span of the guide sheet (7) is halved, so it can be made thin and flexible, making it easy to follow the entrance of the threshing device (4). It is difficult for grains to fall into the gap (a), and since the attachment/detachment handle (9) is used in two stages as a support for the guide sheet (7), it is simple and inexpensive.
