Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reaping and harvesting machine that cuts and harvests grain culm in a field so as to prevent the grain culm from being entangled with the body as the body progresses.

[0002]

2. Description of the Related Art A mowing harvester has a mowing section on one of the left and right sides of the front of the machine and a driving section on the other side of the front of the machine, such as a self-removing and relatively small combine. I have something to prepare. In such a harvester, the orientation of the machine is set so that the mowing part side is the uncut side (there is a culm) and the operating part side is the already mowed side (there is no culm), and the By running along one side, the culm is cut by the reaper while preventing the culm from hitting the driving section. This is normal mowing work.

In contrast to the above-mentioned ordinary mowing work, there is a case where the middle cutting work is carried out at the beginning of the ordinary mowing work to travel the center of the field to mow the grain stalks. In the middle-splitting work, grain culms are present on both the left and right sides of the machine body, and there is a risk that the operating unit pushes down the grain culm or the operating unit entangles the grain culms. As a result, there is a vehicle equipped with a grass body that is located in front of the driving unit and guides a grain culm in front of the driving unit to the lateral outside of the driving unit as the machine body advances.

[I] In a reaper harvester having a reaping section on one of the left and right sides of the front part of the machine body and a driving section on the other side of the front part of the machine body, According to the feature of claim 1, when the grass culm for guiding the grain culms to the lateral outside of the driving unit along with the progress of the machine body is provided, the grain culm located in front of the driving unit is used to advance the machine body. Along with this, the posture of the grass body is changeable over a working posture in which it is guided to the lateral outside of the driving unit and a storage posture in which the grain culm in front of the driving unit is not guided to the lateral outside of the driving unit. According to the feature of claim 2, the front part of the grass body is attached to the lower rear part of the divider on the operation part side in the cutting unit, and the grain culm located in front of the operation part and in front of the operation part is attached to the body. With the progress, the posture of the grass body is freely changeable over a working posture that guides the lateral side of the driving unit and a storage posture in which the grass body is located along the rear of the divider.

Thus, according to the features of claim 1 (claim 2), for example, in the split work as described in the prior art, the grass body may be set in the working posture. As a result, in the middle split work, the grain culm in front of the driving unit is guided to the lateral outside of the driving unit by the grass body as the machine progresses, so the driving unit pushes down the grain culm, or the grain culm is placed in the driving unit. Less likely to get tangled. Next, if the grass body is set in the retracted position, when it turns on the edge of the field or on the road or travels along the edge of the field, it will hit the block, for example, on a short block. When the reaper harvester is carried on the bed of a truck for transportation, the side board of the truck is less likely to hit the grass when it is erected.

[II] According to the feature of claim 2, the front part of the grass body is attached to the rear part of the lower part of the divider on the operation side of the mowing part, and the grass body is positioned so as to follow the rear part of the divider. The posture of the grass body can be freely changed to the retracted posture. In this case, since the divider is an existing member and has a certain width, the feature of claim 2 is that the space behind the divider, which is the existing structure, is used to store the grass body in the retracted posture. Positions can be provided.

Since the rear part of the divider described above generally faces upward (see, for example, FIG. 1), according to the feature of claim 2, the front part of the grass body in the retracted posture is the lower side of the grass body. The rear part is on the upper side, and the grass body is in a state of being oriented in the vertical direction, and the rear part of the grass body is located at a relatively high position. With this, according to the feature of claim 2, when the grass body in the stored posture is set to the working posture,
The operator can easily hold the rear part of the grass body, and can easily set the grass body in the working posture by holding the rear part of the grass body.

According to the features of claim 1 (claim 2),
In a harvesting harvester equipped with a mowing section on the left and right sides of the front part of the machine and a driving section on the other left and right sides of the front part of the machine, the grain culm in front of the operation section will move to the side of the operation section as the machine advances. When equipped with a grass body that guides to the outside, by configuring the grass body so that it can be set in the retracted position, for example, you can hit the grass body on a short block or stand up the side plate of the truck bed. It was possible to reduce the damage to the grass bodies by reducing the chance that the side plates would hit the grass bodies.

According to the feature of claim 1 (claim 2), for example, when the grass body is set to the work posture in the middle split work, the grain culm in front of the operating section is driven by the grass body as the machine progresses. Since there is little possibility that the grain culm is pushed down by the driving unit and the grain culm is entangled in the driving unit because it is guided to the lateral outside of the section, the function as a weed body can be sufficiently exhibited.

According to a second aspect of the present invention, the space behind the divider, which is an existing structure, is used to provide a position for storing the grass bodies, and a dedicated space for storing the grass bodies. Since it is not necessary to provide the structure, it is advantageous in terms of simplifying the structure of the cutting unit. According to the feature of claim 2, when setting the grass body in the retracted posture to the working posture, the worker can easily hold the rear portion of the grass body, and the rear portion of the grass body facilitates the action of the grass body. Since the posture can be set, the operability of the grass body can be improved.
