Description

[Detailed description of the invention] The present invention relates to a stem culm conveying device in a reaping harvester.

In general, the stem culm conveying device in the above-mentioned reaping and harvesting machines reaps the stem culm with only the tip of the stem culm locked, so the supporting force of the stem culm is weak, and mud etc. If the cutting ability of the reaping device becomes slightly weakened due to the adhesion of the culm, there is a drawback that it may cause a cutting error or disturb the posture of the reaped culm, thereby hindering the transportation of the culm.

Furthermore, when transporting the harvested stem culms to the stem culm processing device mounted on the machine, if there is a joint part in the middle of transportation, the disorder of the posture of the stem culms will be further exacerbated, making it difficult to properly process the stem culms. becomes unable to do so.

In particular, at the time of reaping, the planted stem culm is not sufficiently raised and in an ordered and stable posture, so the attitude of the stem culm is greatly influenced by the treatment of the tip side of the stem culm.

On the other hand, various methods have been used in the past to clamp the area directly above the reaping device with elastic rods, etc. when cutting the stock, but these are only used to improve cutting performance and efficiently guide the stock. This is a method that takes into consideration only two points, and the current situation is that the idea has not reached the point of stabilizing the attitude of the tip side.

Therefore, based on the empirical rule that the attitude of the stem culm is greatly influenced by the treatment of the tip side, the present invention maintains an ordered attitude not only during cutting but also during subsequent vertical transportation. It is an object of the present invention to provide a stem culm conveying device for a reaping harvester that can convey the stem culms to a processing device.

The stem culm conveying device in the reaping and harvesting machine of the present invention lifts the planted stem culms from the front lower part of the machine body by the locking conveyance claw 6 extending near the front end of the stem culm processing device 2 mounted on the machine body. A stem culm locking and lifting conveyance device 5 is provided which sequentially carries out vertical conveyance of the cut stem culm. A guide body 10 is provided opposite the protruding tips of the locking conveyance claws 6, and the guide body 10 is provided at a position corresponding to the upper part of the reaping device 11 of the reaped stem culm locking vertical conveyance path. An elastic clamping tool 9 is provided so as to be deviated toward the stem culm locking and lifting conveyance device 5 side to form a narrower path portion than the reaped stem culm locking vertical conveyance path portion, and The cutting device 11 is characterized in that the cutting device 11 is configured to cut the root side of the planted stem culm while elastically clamping the tip side of the planted stem culm.

That is, at a position corresponding to the upper part of the reaping device 11, there is an elastic clamping tool that elastically clamps the tip side of the planted stem culm that has been pulled up on the starting end side of the stem culm locking and lifting conveyance device 5. By providing 9, it is possible to firmly pinch the tip side of a planted stem culm that is in an unstable state that is prone to lodging immediately after being raised or has not yet been fully raised, so that the disturbance of the tip side can be prevented. This can be prevented and maintained in a stable position.

Therefore, even if the reaping ability of the reaping device 11 is slow, there is no risk of unduly disturbing the posture of the stem culm, and there are fewer cutting errors.

In addition, one stem culm locking and lifting conveyance device is provided with a conveyance claw 6 for lifting the planted stem culm and conveying the harvested stem culm to the processing device 2. 5, in other words, in order to carry out the lifting and vertical conveyance in one continuous conveyance path, there is no need to take over after the conventional lifting and reaping, and furthermore during the conveyance. There is no inheritance of
The harvested stem culm is firmly clamped on the tip side and is conveyed straight and smoothly to the reaped stem culm locking vertical conveyance path while maintaining a stable posture without any inheritance, and is transported as it is without any inheritance on the way. Since the stems are transported to the stem and culm processing device 2, there is no risk that the posture of the stems will be disturbed even during this vertical transportation.

Therefore, lifting, reaping, and subsequent vertical transportation can be performed in an orderly and undisturbed posture, which greatly contributes to the efficient operation of the stem and culm processing device 2.

The mode of carrying out the present invention will be described in detail based on the illustrative drawings. 1 is a combine main body which is a reaping harvester, and a threshing device 2 for threshing the stock by holding the plant base with a field chain 3 is installed, and the stem culm is attached to the front.
