DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine weeding structure for separating uncut mowing grain culm from a body, which may cause the body to fall over.

[0002]

2. Description of the Related Art Conventionally, as a weeding structure of this type of combine, for example, as disclosed in Japanese Utility Model Laid-Open No. 3-14919, a weeding tool at an uncut mower end of a pre-cutting section is used. Known is a structure in which a weeding rod is fixedly installed over a threshing device.

[0003]

However, in the above-mentioned conventional structure, since the rod is fixedly installed on the fuselage, the rod abuts on the stem of the grain culm where the fuselage is likely to fall over. When doing, there is a high risk that the grain stalk will bend by the contact force, especially in the case of a grain stalk that is soft,
Due to the bending, there is a problem that the tip of the cereal stem is bent toward our body, and the tip is caught in the crawler traveling device. The present invention has been made in view of the above-described circumstances, and the body of an uncut mound cereal culm can be smoothly suppressed from falling into the crocus without bending the cereal culm to the crocodile. It is an object of the present invention to provide a weeding structure of a combine that can smoothly return glue culm to an uncut side.

[0004]

According to a first aspect of the present invention, there is provided a combine weeding structure comprising: The vertical member having a wide width in the vertical direction that restricts contact so that the posture is changed away from the fuselage, the rear end side of which protrudes laterally outward of the fuselage from the front end side, and the protruding posture is more than the protruding posture. The rear end side is configured to be able to swing around the front longitudinal axis so that the posture can be freely switched to the position where the rear end side retreats closer to the inside of the machine, and the vertical surface member moves the uncut mowing grain culm backward. It is characterized in that it is provided with an endless rotating band driven to feed.

According to a second aspect of the present invention, in the combine weeding structure according to the first aspect, the endless swivel band is configured to be wide vertically, and the endless swivel band is provided with a drive rotation. In addition, there is provided a rug in which an oblique component force acts upward and rearward on an uncut mound cereal stem.

[0006]

According to the structure of the first aspect of the present invention, the vertical member having a wide width in the vertical direction can be switched between the position of retracting toward the fuselage side and the position of extending laterally outward around the front longitudinal axis. Because it is configured to be swingable, the uncut marrow grain culm will come into contact with the vertical member in the overhanging position in a relatively long range in the direction of the culm, and it will break in the middle. This makes it difficult to cause the uncut moat grain culm to break toward the machine side, and even if it is a soft grain culm, You can prevent it from falling over. Further, since the vertical member is provided with an endless rotating band and is provided so as to be driven so as to send the uncut marrow grain culm backward, the endless rotating band is provided for the uncut mound grain culm. The force that can actively move the grain stalk away from the body by the rotational force of the stalk can be applied, that is, the force that pushes the stalk toward that direction, that is, the force that pushes it in that direction, and the uncut gulberry grain stalk falls further on the body side It has become difficult.

According to a second aspect of the present invention,
The rugs of the endless swivel band push the uncut moat grain stalks to the uncut side while applying a component force upward and backward, so that the uncut moat grain culms that fall down to the aircraft side and stand up smoothly. It can be pushed out to the uncut side.

[0008]

Thus, according to the first aspect of the present invention, the uncut grass grain culm is not mowed in a state in which it is prevented from breaking in the middle of the culm by a wide vertical member in the upright and downside positions. By pushing the uncut moat grain culm, the tip side of the uncut moat grain stalk can be trampled by the crawler traveling device to eliminate problems such as threshing, and the uncut moat grain culm is separated from the body by the endless rotating band. Since the posture can be changed toward the wrinkle, the fall of the uncut gauze culm toward the machine side can be more favorably suppressed.

Further, according to the second aspect of the present invention, the uncut moat grain culm is pushed by the uncut moat while the uncut moat is brought upright by the lugs of the endless rotating band. The body can be further effectively prevented from falling on the culm.
