Description

[Detailed Description of the Invention] The present invention includes three pulling devices arranged side by side in the left and right direction of the machine so as to pull up three rows of planted stem culms, and a reaping device arranged behind them. The present invention also relates to a reaping harvester equipped with a rear conveyance device that transports the harvested stem culms toward the threshing section at the rear of the machine body.

Conventionally, in this type of reaping and harvesting machine, for example,
As shown in Publication No. 22109, the stalk culms that have been pulled up and reaped are once transported horizontally to near the side edge of the machine body by a cross-feeding device, and then transferred to the rear conveyance device and transferred to the threshing device. However, in this case, it is necessary to provide a horizontal conveyance device which is a big loss for conveying the stem culms after reaping in the horizontal direction. Also, since the transfer direction of the stem culm is changed greatly at the joint point when transferring from the horizontal conveyance device to the rear conveyance device, the transfer effect on the tip of the stem culm occurs, and the transfer is difficult. There was a risk that the posture would be disturbed and the seeds would fall off.

The present invention reduces the disturbance in the posture of the conveyed stem culm by configuring the conveyance direction of the stem culm from the lifting of the stem culm to the rear conveyance device to be along the direction of movement of the machine body as much as possible, and also prevents large-scale lateral conveyance. The object of the present invention is to provide a reaping/harvesting machine capable of merging stem culms and transferring them to a rear conveyance device using a simple conveyance means without using any equipment.

The characteristic structure of the reaping and harvesting machine according to the present invention is that in the reaping and harvesting machine as described at the beginning, two of the three pulling devices are arranged so that the pulling paths of the husband and husband are opposite to each other. At the same time, another one is arranged next to the two lifting devices with the lifting path located inside the fuselage, and the other one is arranged in parallel with the lifting path located inside the fuselage, and the other one is located in the rear position of the central lifting device. At the same time as positioning the starting end of the rear conveyance device, a pair of left and right V in plan view of the locking conveyance device
locks arranged in a letter shape, and with the rear end of the rear conveyance device being deviated toward the side where the other one of the lifting devices is present, and whose conveyance direction corresponds to the side of the two lifting devices arranged opposite to each other; Constructed so as to be substantially along the stem culm conveying direction of the conveying device, and
The stem culms pulled up by the two pulling devices are combined and cut, and the stem culms pulled up and cut by the other one pulling device are combined at the starting end of the rear conveyance device. This configuration provides the following effects.

In other words, the pair of left and right locking conveyance devices are arranged in a V-shape in plan view so that the stem culm is pulled and conveyed diagonally backward from both left and right sides toward the starting end of the rear conveyance device. The starting end of the rear conveyance device is moved while the flow of the stem culm leading to the conveyance device is shifted along the direction of movement of the aircraft as much as possible, without making a sudden change in direction from parallel to the direction of movement of the aircraft to a direction perpendicular to the direction of movement of the aircraft. In addition, the stem culm transferred by the locking conveyance device moves with a certain degree of backward speed component, and can move from side to side. Since they are transferred from both sides and merge, when the merging stem culms are transferred to the rear conveyance device, the direction of the resultant force can be further adjusted by merging the stem culms that are diagonally toward the rear center side. By directing the stems more in line with the direction of movement of the aircraft, it successfully eliminates the phenomenon of swinging of the stem culms, and the stems are moved to the rear in a numerous manner, allowing for smooth transfer of the stems to the rear transport device. be.

Moreover, the culms of the stems do not join together at the starting end of this rear conveyance device, or the stalks pulled up and cut by each pulling device individually reach the starting end and join together all at once, or they are arranged in equal amounts with each other. It is not a form in which several groups that have been merged together reach this starting point and are merged all at once, but the stem culms that have been raised by the two pulling devices are combined and cut, and the other one Since the stem culm pulled up and cut by the pulling device is merged with the stem culm at the starting end of this rear conveyance device, smooth and good merging that could not be seen with conventional devices has become possible.

In other words, the stem culms that are conveyed from the two lifting devices join together and increase their volume, so that their postures are less likely to be disturbed by friction between the stem culms and become stable. In order to transport the stem culm smoothly and easily, and to merge the stem culm from the other pulling device side, which has a much smaller mass, with respect to the merging stem culm, which has a large mass, With this merging stem, the merging impact can be extremely reduced, and the transport direction is transferred from the locking transport device to the rear transport device without major changes, further reducing the risk of posture disturbance. Since the culm is joined to the culm with a smaller mass from the side of another pulling device, it is possible to further reduce mutual posture disturbance at the time of merging. This can be done smoothly and favorably with little risk of mutual posture disturbance.
