Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for controlling the stock part when the stock part of the harvested husk is conveyed by the stock transport device and is supplied to the handling bundle transfer device of the threshing device in a combine harvester. The present invention relates to a delivery guide device.

When threshing is carried out using a combine harvester, in order to feed the tip side of the harvested husk to the fixed position of the supply port of the threshing machine, the husk side of the husk is divided into short and long culms. Depending on the case of the culm, different positions of the plant base must be handled and the receiver must be delivered to the east transfer device.

Therefore, the stock transfer device, which is configured to pinch a certain part of the stock part of the cut culm and send it toward the handling and bundle transfer device, generally has its transfer end side facing the side of the combine. It is structured so that it can be extended freely.

In other words, this type of stock transfer device has a stock transfer chain that is suspended between, for example, a tin rocket wheel on the starting end, a sprocket wheel on the terminal end, and a driving sprocket wheel, and is also equipped with a chain slack removing device. However, such a stock transfer device is configured to be able to rotate outwardly around the sprocket wheel on the starting end side.

However, the chain of the stock transfer device is rotated along a plane that slopes backward, and the chain of the stock transfer device is rotated along a vertical plane along the front-rear direction. Furthermore, since the stock head conveyance chain is provided with a clamping rail for clamping the stock head between the chain and the stock head conveyance chain, there is a gap between the stock head conveyance device and the handling bundle transfer device. There is inevitably a gap in the delivery area,
Furthermore, since the terminal end of the stock transfer device is displaced as described above, the following problem occurs in this gap.

That is, when the shell culm is a short culm, the stem part of the shell culm, which is held between the stock conveying chain and the clamping rail, is held in an upright state with its lower end facing downward. When the gap is reached and the stock head is released from the stock transport device, the tip side of the culm with the stock base freed is laid down to a horizontally laid down position, and then transferred by the stock transfer device. Because it is only held, in this gap, the stock head hangs down to a position where it collides with the handling east transfer chain in front of it, and the stock head is lying on the handling east transfer chain. If the culm is a long culm, as soon as the stock part is released from the clamped state between the stock transport chain and the clamping rail, Furthermore, since the culm is long and heavy, the culm, whose tip side is only loosely supported between the conveying claws with large gaps, tends to slip downwards.

This invention allows the culm to be extremely smoothly transferred from the terminal end of the stock transfer device to the start end of the handling east transfer device, even in the case of long culms or short culms, without causing such troubles. The purpose of the present invention is to provide a transfer guide device for the stock head section of a combine harvester, which is configured so that the conveyance start end side thereof is pivoted at an appropriate position on the body of the combine harvester. Below the stock transfer device, which is configured to be able to freely displace the transport end side laterally, there are provided a link whose one end is pivoted at an appropriate position on the machine frame of the stock transfer device, and a link whose one end is pivoted at an appropriate position on the body of the combine harvester. A link mechanism is provided in which the supported links are connected to each other, and the link that is pivotally supported on the machine frame side of the stock transfer device is used to transfer the threshing machine from near the transport end of the stock transfer device. When the base end of the stock base receiving rod extending to the side of the device is fixed, and the transport terminal side of the stock base conveying device is rotated outward, the stock base receiving rod is rotationally displaced inward. There is provided a stock transfer guide device in a combine harvester, characterized in that the device is configured to be forced to move.

Also, the husks cut by the reaping device 7 provided at the front lower part of the threshing device 1 are supplied to the threshing device 1 by an ear tip conveying device 8 and a stock head conveying device 9. However, in the combine harvester of this embodiment, the planted culm split by the weed cutting bodies 10, 10 is pulled up by the pulling device 11 and the starting end side of the ear tip conveying device 8. Above, while the tip is being conveyed, the root of the stock is cut off by the reaping device 7, and the cut culm is transported by the tip of the tip conveying device 8 and the tip of the stalk conveying device 9. His posture was tilted sideways,
The tip side of the shell culm is directly supplied to the tip side of the shell culm supply port 4 by the tip conveyor 8, and the stock side is transferred from the stock transfer device 9 onto the handling east transfer chain 5. More precisely, the stocks are transferred from the stock transport device 9 onto the handling bundle transfer chain 5 via the delivery guide device according to the present invention.

In the figure, reference numeral 12 denotes a grass divider board installed near the front end of the grass divider rod 13 that extends to the uncut side of the combine.
This weed divider plate 12 prevents the fallen culm from wrapping around the lifting claw 11a extending outside of the pulling device 11, and also prevents the pulling claw 11a toward the outside to prevent danger. This covers the exposed parts of the
