Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention aims to provide a first and a second mowing device provided at the top and bottom to improve the threshing efficiency and minimize the amount of stumps left. The present invention relates to a pre-cutting pretreatment device for a culm-type combine harvester.

[Conventional technology]

As a type having such a two-step upper and lower reaping device, conventionally, an upper and lower two-stage reaping device is arranged in front of and behind an auger-type lateral feeding and conveying device to cut a planted grain culm as the machine progresses. (For example, JP-A-63-7711).

[Problems to be Solved by the Invention] In this case, when mowing with the first mowing device on the upper side, scraping with the front scraping reel applies the planted culm to the first mowing device with the scraping reel. Since this reel acts as a support for the grain culm to be mowed, when the mowing is performed by the second mowing device, the stem culms left uncut only contact the cutting blade in an independent state. Therefore, there was a case where the culm easily escaped forward, and the cutting height of the second cutting device was not cut to the desired height. Therefore, the cutting height becomes uneven,
Next, when performing the plowing work, a high stump hinders workability and is not preferable.

An object of the present invention is to make a simple change to the arrangement relationship of two mowing devices, to provide one that can reduce the uncut amount of the planting plant, and to provide one that can improve the mowing performance of both mowing devices. .

[Means for solving the problem]

The characteristic configuration according to the present invention is: a first reaping device for cutting a root side portion of a planted grain culm caused by a raising device; and a first reaping device located rearward and upward of the first reaping device. Provided with a second cutting device for cutting a lower part from the tip portion of the obtained grain culm, and provided with a vertical transport device for transporting the grain culm toward the rear above the first harvesting device and the second harvesting device, The vertical transfer device is composed of a stock-source-holding transfer device that holds and transfers the root side part of the grain culm and an ear tip locking transfer device that locks and transfers the ears side part of the grain culm, A feeding and conveying device for conveying the conveyed grain culm sent from the conveying device toward the threshing device is provided, and the grain culm conveying speed of the stock holding device is set to be higher than the conveying speed of the tip locking conveying device. The effect is as follows.

[Operation] As a reaping device, the second reaping device is arranged rearward and upward with respect to the first reaping device for cutting the plant base of the planted culm to further cut the corned culm. Since the grain culm is subjected to the cutting action of the first reaping device in a state where it is maintained in the standing state by the raising device, it has the supporting action of the raising device and is subjected to the cutting action in the free standing state as in the conventional case. It is easier to cut compared to the case. Moreover, when the grain culm is cut, the grain culm is held in a vertical position by the stock holding device and the tip locking and conveying device at the same time, is conveyed in the vertical position, and is cut below the tip portion by the second cutting device. It Therefore, even when the cutting is performed by the second reaping device, it is supported at the upper and lower portions of the vertical conveying device, and the cutting is good.

However, if the grain culm transporting speed of the stock holding device and the tip locking transporting device is set to the same speed, as shown by the phantom line in FIG. 6, the resistance at the time of cutting by the first reaping device (5) For this reason, the stock source will be delayed, and it will be fed to the second reaping device (4) in a tilted backward posture,
There is a possibility that the cutting performance of the second reaping device (4) may decrease because the carrying speed of the stock holding device (10) is made higher than that of the tip locking carrier device (11).
On the contrary, it is possible to maintain the posture of the transported grain culm to be mowed by the second mowing device (4) in a desired vertical posture, and improve the mowing performance of the second mowing device (4).

〔The invention's effect〕

As a result, the harmful effect of the vertical conveying device, which is required by first arranging the first reaping device for cutting the planted culm in the front lower part and arranging the second reaping device in the rear upper part (second part)
(The grain culm to be cut by the reaping device is in an inclined posture), the grain culm conveying speed of the stock carrier holding and conveying device is set higher than the grain culm conveying speed of the tip locking conveying device, We were able to improve the harvesting performance in the compared to the conventional configuration.

Further, since the tip locking transporting device does not carry it in advance, the tip part of the transported grain culm will not be wound even when the locking claw is switched to the retracted posture at the end of the transportation.
It can be handed over smoothly to the rear auger type lateral feeder.
