Description

[Detailed description of the invention] This invention transports the husk that has been raised by a pulling device and cut by a cutting blade in a nearly vertical position to the threshing device at the rear of the machine by a culm conveying device. The present invention relates to a reaping and supplying device for a self-removing combine harvester, which is configured to feed the husk to a threshing device with the culm in a substantially horizontal position at the stage of transferring it to the feed chain.

In this type of self-stripping combine harvester, when the husk that has been cut by the cutting blade placed at the front of the machine is transported to the threshing device by the culm conveying device, the husk is kept in an approximately vertical position as described above. It is necessary to change the posture of the culm to a nearly horizontal position, and when adjusting the cutting height, turning the machine at the edge of the field, and driving on the road, the height of the cutting blade, pulling device, culm conveying device, etc. must be adjusted. It needs to change.

At this time, with the conventional conveyance device, the stock side of the culm is held between the ends, and the tip side is gradually pushed inward by the locking conveyance device while changing the posture, which saves space for conveying the culm. Even if it is necessary to secure a relatively wide area, it will hinder the downsizing of the entire aircraft, and there are also drawbacks such as the shell culm conveyance posture being disturbed and the extraction falling due to the change in posture.Furthermore, The swinging fulcrum position of the support frame that supports the reaping supply section was set to be significantly shifted vertically or longitudinally relative to the culm supply port of the threshing device, so the cutting height had to be adjusted. In this case, the transfer position between the shell culm conveying device and the feed chain installed on the upper part of the support frame changes greatly, and there is a problem that smooth transfer cannot be performed.

The purpose of this invention is to eliminate the drawbacks of the conventional device mentioned above, to make the space for transporting the shell culm relatively small and to make the machine more compact, while also preventing holes in the transport posture of the shell culm, and preventing the removal of the shell from occurring. The husk culm can be well connected to the feed chain without the risk of causing husk culm, and even when the cutting height is adjusted, the husk culm feeding port of the husk conveying device and threshing device can be easily connected to the feed chain. To provide a reaping and feeding device for a self-removal type combine harvester, which can reduce changes in relative posture with a start end of a feed chain close to the feed chain, and can connect bridges without any trouble.

The characteristic configuration of the reaping and feeding device for a self-removal type combine harvester according to the present invention is that a threshing device with a feed chain along the machine traveling direction is mounted on the traveling device, and the feed chain is centered on the axis near the starting end of the feed chain. A support frame configured to be vertically rotatable and fixed extends toward the front side of the machine body, a lifting device and a cutting blade are provided at the front end of this support frame, and a rear part of the lifting device is installed at the top of the support frame. a shell culm conveying device having a lower starting end and an upper end near the feed chain starting end;
This shell culm conveying device is formed of two upper and lower conveying devices, a stock-side conveying device and a head-side conveying device, and the shell culm holding surface is configured in the vertical direction, and the conveying start end of the feed chain is connected to the shell culm. The feed chain is tilted forward in the same way as the conveying device, and the conveying start end of this feed chain overlaps the lower end of the end of the shell culm conveying device in the front and back of the conveying direction, and the upper and lower ends of the shell culm conveying device It extends as a joint surface that supports the shell culm in the horizontal direction, which is substantially orthogonal to the shell culm holding surface in the direction, and the following effects are achieved despite the sagging structure.

That is, the shell culm conveying device is configured to convey the cut shell culm with the shell culm holding surface facing in the vertical direction, and the shell is attached to a feed chain that clamps the shell culm in a horizontal direction approximately perpendicular to the clamping surface. Since the culm is to be passed on to the bridge, the posture of the shell culm is changed and the bridge is to be passed on, but the posture of the culm is maintained in an almost upright position during transportation, which requires less space for transportation. This is a device that can transport the shell culm, which is effective in making the entire aircraft more compact.In addition, there is no need to change the attitude of the shell culm significantly during transportation, so there is less disturbance in the attitude of the shell culm. Because the starting end of the feed chain enters below the end of the device and overlaps with each other at the front and back in the conveying direction, the receiver, which is most likely to drop during culm removal, comes off from the culm conveying device at the time of transfer. It is possible to prevent the shell culm from always riding on the starting end of the feed chain and falling off from the conveyance system, and it has the advantage of being able to carry out good shell culm conveyance with less posture disturbance and falling off. It is something that can be done.

Furthermore, even if the support frame is changed in the vertical position to adjust the cutting height, since the swing fulcrum position of the support frame is the axis near the start end of the feed chain, the culm relative to the start end of the feed chain can be adjusted. Smooth jointing can be performed without greatly changing the end position of the conveyor, and avoiding disturbances in posture during jointing of the shell culm due to large changes in jointing distance and jointing posture. It is something.

Embodiments of the present invention will be described below based on the drawings.
