Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rush harvester that continuously cuts and binds rush in a field.

[0002]

[0007] Conventionally, Japanese Patent Publication No. 7-12
As disclosed in Japanese Patent Laid-Open No. 255-255, there is a technique in which a cutting section that takes in rush and cuts a root of the rush and a binding section that binds the rush harvested from the cutting section are provided to form a rush bundle continuously. The operator had to manually carry out both the driving operation and the loading of the rush bundles, because the rush bundles delivered from When both operations are performed, problems such as meandering traveling and rush clogging at the binding portion are likely to occur, and it is not easy to simplify the handling operation, and the above-mentioned operations are performed by two workers. There is a problem that labor saving cannot be easily attained by performing each process individually.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a rush harvester having a cutting section and a tying section for continuously cutting and tying rush, and an elevator for lifting a rush bundle discharged from the tying section. A conveyor for horizontally moving a pile of rushes lifted by the elevator, wherein a lifted upper end of the elevator and a feed start end of the conveyor are overlapped in a side view, and rushes discharged from a binding portion by the elevator and the conveyor. The stack can be automatically unloaded, making it easy to improve harvesting workability, etc., and the elevator upper end part and the conveyor start end part are overlapped, so that the rushed grass bundle in a sideways posture is smoothly moved to the conveyor end side. In this way, it is possible to eliminate problems such as damage to the rush grass due to the rush bundle posture being disturbed during transportation.

[0004] Further, a bundle conveying device equipped with an elevator and a conveyor for conveying a rush of grass is slidably mounted in the direction of the core of the rush of grass, and the position of the bundle transport device is adjusted according to the culm length of the cut rush. It can be adjusted and transported while supporting the central part of the rush bundle, which can eliminate such problems as the support position of the rush bundle being offset to either the stock side or the tip side and the transport posture of the rush bundle being disturbed. is there.

[0005] Further, the elevator is provided with a gutter which receives the bundle of rushes released from the binding portion and passes it to the conveyor.
A part of the rush bundle can be easily prevented from hanging down by the support of the gutter, and for example, even if a rush plant which is hard to be damaged is tied, the rush head side can be transported without hanging down,
It is possible to bind stocks that hardly reduce the commercial value of rush and to easily prevent damage to the rush by disturbing the transport posture of the rush.
