Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain culm inheriting device for a combine threshing section, which allows a harvested grain culm from a reaping section provided in front of the threshing section to be passed to the threshing section.

[0002]

2. Description of the Related Art Conventionally, the starting end of an under-type feed chain opposite to the lower side of a pinch rail is used to convey the inherited culm culms in the reaping section to the threshing section. To the front,
On the extension part, a inheritance guide is extended from the mowing part or threshing part to smoothly inherit the mowing grain culm from the mowing part between the feed chain and the pinch rail. Although the device itself is generally disclosed and known, according to this device, in the case of a manual operation of supplying a hand-cut material such as pillow cutting to the threshing part for processing, the supply operation is easy. It is unsatisfactory in terms of performance, selectability and switching operation of inheritance guides.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention facilitates the work of supplying the grain culms to the threshing section and enhances the selectivity of the grain loss when performing the above-mentioned manual handling work, and further, the inheritance is carried out. The present invention has been made with the object of improving the work performance in the case of switching from a series of threshing and threshing work to manual handling work by making the guide switching operation one-touch.

[0004]

In order to achieve the object described in the preceding paragraph, the first means of the present invention is, as a first means thereof, an under-type field member which is opposed to the lower side of the pinch rail.
Extend the start end of the dochien forward, and extend the inheritance guide from the mowing part on the extension so that the harvested culm from the mowing part can be inherited between the feed chain and the picking rail. In the grain stalk transfer device, the transfer guide is made movable to form a grain stalk supply path between the start end of the pinch rail and the tip of the transfer guide, and the transfer guide is cut. It is characterized in that it is configured to be used as a placing rack for hand-operated grain culverts by displacing the row portion to a higher position,
As a second means, the starting end of an under-type feeder chain, which is opposite to the lower side of the pinch rail, is extended forward, and a inheritance guide is attached to the extending portion to remove it from the mowing section. In the grain culm inheriting device that can inherit the harvested grain culm between the field chain and the sandwich rail, the handing grain culm can be supplied by separating the inheritance guide from the extension of the field chain. In addition, the separating operation is such that the chaff sheave fins of the swing selecting body are interlocked in the closing direction,
In addition, as a third means, the starting end of an under-type feed chain, which is opposed to the lower side of the pinch rail, is extended forward, and a threshing part is attached to the extension guide. Then, in the grain culm transfer device for transferring the harvested culm from the reaping unit between the feed chain and the pinch rail, the support to which the inheritance guide is attached is a fulcrum on the supporting shaft of the threshing unit. And the movable body is attached to the support body so that the movable body can be moved up and down with an operating shaft parallel to the support shaft and spaced apart from the supporting shaft as a fulcrum. And the operating body are provided with engaging portions that engage with each other, and the upward pushing force of the inheritance guide applied to the operating body itself causes the engaging portion of the operating body to restrict the movement of the engaging portion of the support body to support it. The upper part of the body is prevented from moving upward, and the engaging part of the actuating body moves the engaging part of the supporting body upward when the operating body is moved upward. It is characterized in that it has a configuration that is moved upward to support Te.

[0005]

Therefore, according to the first means, the harvested grain culm, which is conveyed from the cutting portion by the cutting portion, is placed on the extension portion of the feed source in the tilted posture and is held from above by the inheritance guide. It is then transported and transferred to the start end of the pinch rail. Also, when switching to manual operation, if the inheritance guide is moved to the front edge, a grain culm supply path is formed between the pinch rail and the tip of the inheritance guide, and the harvesting part of the inheritance guide is formed. As the saw moves to the upper position, the hand-croped grain culm is placed on the inherited guide portion displaced to the upper side and fed from the grain culm supply path between the feed chain and the start end of the pinch rail. The treatment room is transported laterally.

[0006] In the second means, the harvested grain culm from the reaping section is placed on the extension section of my field feeder, and the plant is pressed by the inheritance guide to be conveyed and pinched. Since it is inherited at the starting end of the rail, switching to manual operation separates the inheritance guide from the extension part of the feed chain. It is supplied from the top of the unit by a predetermined amount between it and the start end of the pinch rail, and due to the separating action of the inheritance guide, the fins of the oscillating sorting body are interlocked with each other in the closing direction to optimize the distance between the fins. The gap is corrected to improve the sorting of the handled products.

Further, according to the third means, the harvested grain culm from the reaping section is placed on the extension section of my field feeder and the stock is pushed by the inheritance guide to be conveyed and pinched. -It is inherited at the starting end of the le, but at that time, even if the amount of the harvested grain culm fluctuates greatly and the pushing force of the grain culm acts on the inheritance guide, the actuation body attaches the inheritance guide. The upward movement of the support is prevented so that the cut culm can be reliably conveyed to the start end of the pinch rail and inherited. Then, when switching to the manual operation, the support body is separated upward together with the inheritance guide by operating the actuating member so that the hand-cut grain culms can be easily supplied.
