A detector 11 for detecting that the operating arm 7a of the reaping clutch 7 has been operated on the disengagement side is provided, and the detector 11 and the travel stop device 12 are linked together, and the detector 11 and the traveling A linkage state switching device 13 is provided between the stop device 12 and the detection device 11 and the travel stop device 12 to switch between a linked state and a linked release state.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reaper such as a binder or a straw harvester.

[0002]

[Prior Art]

 Conventionally, in a reaper such as a binder, the cutting work is introduced so that the splitting work can be performed while the handle is released, for example, as shown in Japanese Utility Model Laid-Open No. 60-153937, beside the planting culm introducing route. The sensor bar, which is swung backward by the contact with the planted culm, is provided in an urged state, and the sensor bar and the operating arm of the reaping clutch are mechanically linked so that the sensor bar When the reciprocating rocking above a certain level, the reaping clutch is automatically and reversibly entered and operated, and is planted on the sensor bar by the machine that can run by itself when the handle is released. When the standing grain culm is brought into contact with the cutting clutch, the cutting clutch is automatically operated, and when the planted grain culm is lost at the end of the field, the cutting clutch is automatically disengaged.

[0003]

[Problems to be solved by the device]

 Although the reaping clutch is turned on and off automatically by detecting the presence or absence of grain culms, the aircraft must be stopped manually, so at the end of one stroke, the aircraft will be in a ridge. There was the annoyance that the worker had to chase the aircraft to stop it so that it would not collide. The present invention solves the above-mentioned drawbacks and solves the new problems caused thereby.

[0004]

[Means for Solving the Problems]

 The characteristic configuration of the present invention for achieving the above-mentioned object is to provide a detection device for detecting that the operation arm of the mowing clutch is operated to the disengagement side, and to link the detection device and the traveling stop device, Between the detection device and the travel stop device, a linkage state switching device for switching the detection device and the travel stop device between a linked state and a linkage release state is provided.

[0005]

[Action]

 As shown in FIG. 1, when the machine reaches the end of the field, the cutting clutch 7 is automatically disengaged by the sensor bar S's detection without a culm, and the operating arm 7a of the slicing clutch 7 is operated. The switch 11 as a detection device detects that the switch has been operated to the cut side, and the energization of the engine ignition circuit 12 as a travel stop device is cut off to automatically stop the aircraft. In this way, if the machine's traveling is automatically stopped in conjunction with the detection of the presence of grain culms, when the machine reaches the edge of the field during work such as mowing work with a handle, The detection of the absence of the vehicle causes a new problem that the aircraft stops traveling each time, but the detection device 11 and the travel stopping device 12 are linked between the detection device 11 and the travel stopping device 12. Since the changeover switch 13 is provided as a linkage state switching device for switching between the detection device 11 and the traveling stop device 12, the linkage state switching device 13 links the detection device 11 and the travel stop device 12 when the operator holds the handle. By canceling the above, it is possible to eliminate the inconvenience that the machine stops traveling each time the machine reaches the end of the field.

[0006]

[Effect of the device]

 As a result of the above configuration, when the aircraft reaches the end of the field during the handle release work such as splitting work, it is not necessary to chase the aircraft to stop the aircraft, and when performing work with the handle, A new inconvenience that the aircraft stops traveling each time it reaches the end of the field can be eliminated.

【Example】

 An embodiment of the present invention will be described below with respect to a binder which is an example of a reaper. As shown in FIG. 3, a raising device 1 for raising the grain culm, a mowing device 2 for mowing the raised grain culm, and a mowed grain culm on one side of the body as shown in FIG. Further, a horizontal transport device (not shown) for transporting the grain to each other and a binding device 3 for binding the grain culms transported in the horizontal direction are provided. Then, the transmission M is directly transmitted from the mission M directly connected to the engine E to the pair of left and right wheels 5 via the chain transmission 4, and is also raised from the transmission M via the transmission shaft 6 and the cutting clutch 7 at the tip of the transmission shaft 6. It is configured to be transmitted to the reaper drive shaft 9 which is integrally linked with the drive device drive shaft 8. Then, as shown in FIG. 1, a sensor bar S, which is swung backward by the contact with the introduced planting culm, is provided beside the planting culm introducing route A in an extended urging state. The server S and the operating arm 7a of the reaping clutch 7 are linked through a mechanical linkage mechanism 10 including a link mechanism, and the reaping clutch 7 is automatically moved when the sensor bar S is moved backward more than a certain amount. In addition, it is configured to be able to enter and operate reversibly. A switch 11 is provided as a detection device that contacts when the operation arm 7a of the harvesting clutch 7 is operated to the cut side. The switch 11 is linked to an ignition circuit 12 of the engine as a travel stop device. Thus, the ignition circuit 12 of the engine is de-energized to stop the traveling of the machine body when the cutting clutch 7 is disengaged. A changeover switch 13 is provided as a linking state changeover device in the link circuit between the switch 11 and the engine ignition circuit 12. As shown in FIG. 2, the wheel 5 is composed of a resin wheel body 5A in which all of lugs, ribs, hubs, etc. are integrally formed of reinforced plastic, and rubber externally fitted to the resin wheel body 5A. It is composed of a cover tire 5B and a weight reduction of the wheel.

[Other Embodiments] As the traveling stopping device, the traveling clutch in the mission may be configured as an electromagnetic traveling clutch, and the electromagnetic traveling clutch may be configured to be stopped. Further, it is not limited to electrical, and may be constituted by a mechanical traveling clutch and operated mechanically. Furthermore, the harvester may be a straw harvester.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
