Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a mowing unit, which comprises a cutting device for cutting planted grain culms and a feeding device for feeding the cut grain culms to the threshing device, in the front part of a traveling vehicle equipped with the threshing device. The present invention relates to an all-cullet throw-in type combine that is vertically movable.

[0002]

2. Description of the Related Art Generally, in a combine having the above-mentioned structure, since harvested grain culms are fed to a whole culm threshing device, for example, harvesting of grain culms having a grained portion only at the upper end of the culm such as rice and wheat. Sometimes, it is desirable to cut only the tip of the grain culm and send it to the threshing device from the viewpoint of improving the processing capacity,
Conventionally, with a combine harvester having the above-mentioned configuration, as described above, there is a case where only the tip portion of the grain culm is harvested (not described in the reference).

[0003]

However, in the work of cutting only the tip portion of the grain culm as described above, the uncut plant remains on the ground, which hinders the next plowing work. There is room for improvement. Therefore, it is conceivable to provide a cutting blade mechanism or the like for cutting the leftover cutting stock, but if the cutting blade mechanism is simply provided to move up and down, in order to avoid contact with the ridges every time the car body is crossed over the ridges. In addition, it requires time and effort to raise the cutting blade mechanism, which is also inconvenient.

An object of the present invention is to provide a operability mechanism for cutting off uncut plants while making full use of the characteristics of the whole culm input type combine which can improve the work efficiency by harvesting only the tip portion.

[0005]

[Means for Solving the Problems] The technical means of the present invention, which has been devised to achieve the above object, is a cutting device for cutting a planted grain culm, and a mowing device in the front part of a traveling vehicle body equipped with a threshing device. In the all-culm throw-in type combine that connects the mowing section consisting of the feeding device that feeds the grain culm to the threshing device so that it can be moved up and down, the cutting blade mechanism for cutting the stock left uncut by the reaping device can be moved up and down A sensor for detecting the level of the mowing unit is provided, and an elevating mechanism for elevating and lowering the cutting blade mechanism so as to keep the level of the cutting blade mechanism constant based on a signal from the sensor is provided, and The lifting mechanism is
The cutting blade mechanism is configured to be forcibly lifted relative to the cutting unit when the cutting unit rises above a predetermined level, and its action and effect are as follows. .

[0006]

When the above features are configured as shown in FIGS. 1 and 2, for example, the mowing unit is operated by operating the level setter 21 for raising and lowering the mowing unit B as in the case of finishing the harvesting work and overcoming the ridges. If B is raised to a relatively high level, the level of the preset level L
At the same time when the reaper B reaches 1, the signal from the potentiometer 17 for detecting the level of the reaper B
The control device 19 forcibly raises the cutting blade mechanism 14 to the storage position shown by the phantom line in FIG. That is, in this embodiment, as shown in the graph of FIG. 3, the level L of the mowing unit B with respect to the time t when the mowing unit B is raised.
Is represented as a linear graph LB, and the cutting mechanism 1
In No. 4, the ground level G is kept constant until the cutting unit B reaches a predetermined level L1, and thereafter, the ground level G is raised to the storage position (a fixed posture with respect to the cutting unit B). The graph L14 showing the raising operation of the cutting blade mechanism 14 shows a bent state. The lifting mechanism C for raising the cutting blade mechanism 14 is composed of a control device 19, a solenoid valve 20, and a hydraulic cylinder 21.

[0007]

Therefore, since the cutting blade mechanism for cutting the stock left uncut by the cutting device is automatically stored, it is possible to save the trouble of performing a special operation even when the ridge is crossed, and the stock left uncut by the cutting device. As a result of the cutting, the plowing work to be performed next becomes easier.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a mowing unit, which comprises a cutting device for cutting planted grain culms and a feeding device for feeding the cut grain culms to the threshing device, in the front part of a traveling vehicle equipped with the threshing device. The present invention relates to an all-cullet throw-in type combine that is vertically movable.

[0002]

2. Description of the Related Art Generally, in this type of combine, the harvested grain culm is sent to the whole culm threshing device, so that when harvesting grain culm having a grained portion only at the upper end of the culm, such as rice and wheat. , It is desirable to cut only the tip part of the grain culm and send it to the threshing device from the viewpoint of improving the processing capacity,
Conventionally, in the combine harvester having the above-mentioned configuration, as described above, the harvesting work may be performed in which only the tip portion of the grain culm is cut. As described above, in the work of cutting only the tip part of the grain culm, the uncut plant remains on the ground and may interfere with the next plowing work. There is known a combine with a two-step cutting structure in which, in addition to the first cutting blade, a second cutting blade for cutting the root side at a lower position than that is provided (for example, see JP-A-60-244217).

[0003]

However, as described above, if the second cutting blade for cutting the stock left uncut by the first cutting blade is simply provided, the ridge will be removed each time the vehicle body is crossed. In order to avoid contact, not only the mowing part provided with the first cutting blade, but also the second cutting blade needs to be moved up each time.
There is also an inconvenient aspect such as a collision with the ridge of the cutting blade.

An object of the present invention is to provide a operability mechanism for cutting off uncut plants while making full use of the characteristics of the whole culm input type combine which can improve the work efficiency by harvesting only the tip portion.

[0005]

[Means for Solving the Problems] The technical means of the present invention, which has been devised to achieve the above object, is a cutting device for cutting a planted grain culm, and a mowing device in the front part of a traveling vehicle body equipped with a threshing device. In the all-culm throw-in type combine that connects the mowing section consisting of the feeding device that feeds the grain culm to the threshing device so that it can be moved up and down, the cutting blade mechanism for cutting the stock left uncut by the reaping device can be moved up and down A sensor for detecting the level of the mowing unit is provided, and an elevating mechanism for elevating and lowering the cutting blade mechanism so as to keep the level of the cutting blade mechanism constant based on a signal from the sensor is provided, and The lifting mechanism is
The cutting blade mechanism is configured to be forcibly lifted relative to the cutting unit when the cutting unit rises above a predetermined level, and its action and effect are as follows. .

[0006]

When the above features are configured as shown in FIGS. 1 and 2, for example, the mowing unit is operated by operating the level setter 21 for raising and lowering the mowing unit B as in the case of finishing the harvesting work and overcoming the ridges. If B is raised to a relatively high level, the level of the preset level L
At the same time when the reaper B reaches 1, the signal from the potentiometer 17 for detecting the level of the reaper B
The control device 19 forcibly raises the cutting blade mechanism 14 to the storage position shown by the phantom line in FIG. That is, in this embodiment, as shown in the graph of FIG. 3, the level L of the mowing unit B with respect to the time t when the mowing unit B is raised.
Is represented as a linear graph LB, and the cutting mechanism 1
In No. 4, the ground level G is kept constant until the cutting unit B reaches a predetermined level L1, and thereafter, the ground level G is raised to the storage position (a fixed posture with respect to the cutting unit B). The graph L14 showing the raising operation of the cutting blade mechanism 14 shows a bent state. The lifting mechanism C for raising the cutting blade mechanism 14 is composed of a control device 19, a solenoid valve 20, and a hydraulic cylinder 21.

[0007]

Therefore, when the reaper is raised when the ridge is crossed, the cutting blade mechanism for cutting the stock left uncut by the reaper is automatically raised, so that a special operation is required even when the ridge is crossed. It is easy to avoid, and it is easy to avoid damage to the cutting blade mechanism due to forgetting the operation. Then, a cutting blade mechanism that cuts off the stock left behind by the reaping device is provided so that the level is maintained at a constant level, and even if only the tip portion is harvested by the whole culm input type combine, the stock left behind is cut off. Is cut near the ground by the level-controlled cutting blade mechanism, which facilitates the next plowing work. Further, since the raising of the mowing mechanism is not merely the raising of the mowing mechanism in association with the raising of the mowing device, but the raising of the mowing device is relatively relative to the mowing device, a mowing unit provided with the mowing device is provided. Need not be raised higher than necessary.
