Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a culm ridge conveying device for a combine harvester that conveys the tip side of a harvested husk toward a threshing device. The purpose of this method is to transport the tips of the ears, which tend to be disordered, in an orderly and reliable manner.

Next, the embodiment of the present invention will be described in detail with reference to illustrative drawings. The lower part of the machine stand (1) is equipped with a traveling device (2), the upper part is equipped with a threshing device (3), and the front part is equipped with a culm. Reaping device for reaping and transporting (
4) respectively. This reaping device (4) is composed of various devices arranged on a reaping section frame (18). That is, in the front part of the reaping part frame body (18), there is a weed cutting body (17) for shearing the planted culm group, and a lifting tine (10) for changing the culm after cutting into an appropriate reaping posture.
) is constructed by protruding from an endless body (1).
1).

If we distinguish the parts behind the raising case (11) into the stock side and the tip side of the reaped culm, on the stock side, from the front of the machine, there is a cutting blade device (5) and a cutting blade device (5). 'p-JjPda acts on the stock side of the culm cut by
&4*-t to l-1! -Cloudy-111 rub ^ ring i k ((
Ryu) At the rear of the Saiban one-person transporter, the stock side of the culm is sequentially merged and transferred to the rear with a stock transfer device (7), and the starting end is connected to the stock transfer device [(7 feed chain (9)
A vertical conveyor device (8) facing the shell is provided, and on the tip side there is a culm ridge guide plate (12) for guiding the tip side of the shell culm backwards from the front of the body, and a culm ridge guide plate (12) that In order to inherit the shell culm guided by the culm ridge guide plate (12) and engage and transfer it to the shell culm supply port (15) of the threshing device (3) which carries the internal shaft of the rear handling barrel (22). Culm ridge conveying device (13
) (14) are provided. The culm S section conveying device (1
3) (14) is arranged so as to form a confluence part (A),
The shell culm transport device (right) (13) is the shell culm transport device (
Left) It has a continuous conveying action before and after the confluence part (A) with (14). Further, at a position near the shell culm supply port (15) of the threshing device (3), the shell culm seed portion conveying device I
(13) is installed so that the direction of conveyance action is in the direction away from the feed chain (9).

The transmission case (20) transmits power from the engine (not shown) to the reaping device through the sewing machine case (21).

Next, to explain the operation, as the machine moves forward, the planted culm group is separated from the cutting body (17) and raised from the lifting tine (10) of the lifting case (11), and is properly At this time, the root side of the culm is cut by the cutting blade device 7I (15), and the tip side is collected by the culm ridge guide plate (12) and guided to the rear. be done. After that, the stock side of the cut culm is successively raked in (
6), the stock is forcibly transported to the rear by the stock transfer device (7).
), the feed chain (
9), but on the tip side, there is a husk tip guide plate (
After passing through 12), the cut culm is transferred to the husk culm conveying device (13) (14), and the cut husk that is engaged and conveyed from both husk culm conveying devices (13) (14) is transferred to the confluence section (A). ’. In this confluence part (A)-1, the shell culm seed part conveying device (right) (13) has a forced conveyance action, and by this action, the tip side of the shell culm in the confluence part is sequentially conveyed to the rear. .

After that, near the culm supply port (15), the direction of conveying action becomes a direction away from the feed chain (9), and the tip side of the culm is turned sideways and changed to a horizontal position.
At the same time, it receives the combing action and enters the culm supply port (15).

In general, the tip side of harvested husk culms is more likely to be disturbed during transportation than the stem side. This is because the culm is thin and has a relatively heavy panicle attached to its light layer, and it is also bulkier than the stem side. This is obvious from the fact that the numbers are high and overall there is no cohesion. Considering the above characteristics of the harvested husk, it is preferable that the conveying device for the tip side of the harvested husk, that is, the husk culm transport device, be configured with a merging section just before reaching the threshing device. This is because it is easier to prevent disturbances during conveyance, culm removal, etc. by conveying the tip side as a large flow as much as possible, and it is possible to reliably convey the beans to the handling room. Also,
This is because the entire shell culm ridge conveying device can be configured compactly.

Further, by configuring at least one of the shell culm transport devices forming the merging portion to have a forced transporting action before and after the merging portion, problems such as culm retention in the merging portion can be solved.

In addition, the direction of conveyance of the husk seed part conveying device located near the husk supply port of the threshing device is directed away from the feed chain, so that the feeding posture of the culm can be corrected before being fed into the handling room. It becomes possible to do so. In other words, since there is a transport action in the longitudinal direction of the culm, there is a combing action, which corrects the entanglement ν1 of the tips of the culms and delays in transport, and reduces the handling trunk in the handling room as much as possible. Appropriate supply is possible in a position perpendicular to the direction. In addition, the length of the reaping iNN in the front and back direction can be shortened, and the operational structure can be reduced to 1.

In this way, the present invention provides a structure in which the stem side of the plurality of shell culms is placed in the upper channel of the stem conveying device which sequentially obliquely conveys the stem side of the plurality of shell culms toward the rear of the aircraft side and joins them. A plurality of conveying devices and a seed portion guide plate are provided to guide the husk side, and these ear portion conveying devices and guide plates are used to move the husk culm backwards in substantially the same manner as the stock head conveying device. At least one of the plurality of ear conveying devices is arranged continuously before and after the merging portion, and at least one of the plurality of ear conveying devices is continuously connected to the merging portion in the middle of the conveying and reaching the threshing device. By installing the husk culm conveying device located near the husk culm supply port of the threshing device so that the direction of its conveying action is in a direction away from the merging part with respect to the feed chain, The tip side of the cut culm can be forcefully conveyed in a well-organized and smooth manner, preventing stagnation on the tip side of the cut culm at the convergence point in the conveyance route, and immediately before feeding, the culm is combed. It is possible to transport items in an orderly and reliable manner while correcting disturbances during transport due to entanglements, transport delays, etc.
It has the following remarkable effects.
