Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a switching device for an automatic direction control mechanism in a working traveling machine such as a combine harvester equipped with a side clutch lever.

[Problems to be solved by the prior art and the invention]

In general, some of this type of work traveling aircraft are configured to travel while automatically controlling the traveling direction of the aircraft based on detection by a detection sensor. However, in this case, when attempting to rotate by manually operating the side clutch lever to the power off side, it would be inconvenient if the automatic direction control mechanism remains activated, so a changeover switch is installed in the circuit of the automatic direction control mechanism. is provided, and the changeover switch is switched to the OFF side contact by operating the left and right side clutch levers to the power disconnection side, thereby canceling the automatic control by the automatic direction control mechanism. However, with such a machine, if an auxiliary worker is working in the surrounding area or on top of the moving aircraft when attempting to turn the aircraft, the driver may be able to turn the aircraft without noticing. There are cases where it is required as a safety measure that auxiliary workers etc. be made aware of this fact.

Therefore, it is conceivable to turn on the direction indicator lights to give a warning to auxiliary workers, etc., but when the aircraft is turning and performing complex operations such as operating the side clutch lever, it is possible to Since the additional work of switching the indicator lights is required, the operation becomes extremely complicated and users often forget to perform the operation, which continues to be a problem. For this reason, it has also been proposed that the turn signal lights be automatically activated when the automatic control by the automatic direction control mechanism is cancelled. However, if you do this, when you turn right or left while driving on the road, you may turn the steering wheel in the opposite direction and then turn the steering wheel in an inflated state. If it is linked to the side clutch lever, there is a problem that the direction indicator light on the opposite side of the turn will be activated, and it will be necessary to deal with this problem.

[Means and actions to solve the problem]

In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a switching device for an automatic direction control mechanism in a working traveling machine that can eliminate these drawbacks. The circuit of the automatic direction control mechanism that automatically controls the direction is equipped with an automatic control release switch that switches to the OFF side contact and releases the automatic control by the automatic direction control mechanism by operating either the left or right side clutch lever to the power disconnect side. In a work traveling machine that is wired, the automatic control release switch and the direction indicator light changeover switch for manually operating the direction indicator light are connected, and the OFF side contact of the automatic control release switch is connected to the ON side of the direction indicator light changeover switch. The wiring is connected in the circuit from the side contact to the direction indicator light, and the power is supplied to the automatic control release switch side through the OFF side contact of the direction indicator light changeover switch, and the turn signal changeover switch is turned on. The present invention is characterized in that, in a state where priority is given to the operation of the direction indicator light, the direction indicator light on the operated side is activated by operating the side clutch lever to the power disengaged side.

With this configuration, when the side clutch lever is operated to the power off side to cancel automatic control by the automatic direction control mechanism and the aircraft turns, the direction indicator light on the turning side is automatically turned on. This system is designed to activate the system to give a warning to auxiliary workers.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes an operation panel provided on the traveling body of the combine harvester, and the operation panel 1 includes left and right side clutch levers 2, 3, a direction indicator light changeover switch 4, an automatic direction control changeover switch 5, etc. At the bases of the side clutch levers 2 and 3, automatic control release switches 7 and 8 are further provided for opening and closing the circuit of the automatic direction control mechanism 6.

That is, as shown in FIG. 2, the circuit of the automatic direction control mechanism 6 includes, from the automatic direction control mechanism 6 side, an automatic direction control changeover switch 5, an automatic control release switch 7,
8, and direction indicator light changeover switches 4 are connected in series, and the former three switches can be turned on by switching any one of the switches from the ON side contacts 5a, 7a, 8a to the OFF side. is cut off,
Automatic control by the automatic direction control mechanism 6 is released. Reference numerals 9 and 10 are direction indicator lights, and the direction indicator lights 9 and 10 are configured to switch the direction indicator light changeover switch 4 from the OFF side contact 4a to the ON side contact 4b,
The light is turned on by switching to 4c, but in this embodiment, this ON side contact 4
Directional indicator lights 9 and 1 corresponding to b and 4c, respectively
The OFF side contacts 7b and 8b of the automatic control release switches 7 and 8 are connected to the circuit leading to 0. Then, when the side clutch lever 2 or 3 is operated to disengage the side clutch and cut off the power to the automatic direction control mechanism 6 to cancel the automatic control and rotate the aircraft, the side clutch lever 2 or 3 is operated. Power is supplied to the direction indicator light 9 or 10 via the OFF side contacts 7b, 8b of the automatic control release switch 7 or 8, and this causes the direction indicator light 9 or 10 on the side where the side clutch lever 2 or 3 is operated to 10 is automatically lit to warn auxiliary workers and others in the vicinity of the traveling aircraft. Further, in this device, the OFF side contact 4a of the direction indicator light changeover switch 4 is connected to the automatic control release switch 8 side, and when the direction indicator light changeover switch 4 is turned ON, the direction indicator light 9 or 10 is turned on. When the automatic direction control mechanism 6 is turned on, the power supply to the automatic direction control mechanism 6 is cut off.

In the embodiment of the present invention configured as described above, during automatic driving by the automatic direction control mechanism 6, the direction indicator light changeover switch 4 is set to the OFF side contact 4a, and the automatic control release switches 7 and 8 and the automatic direction control The changeover switch 5 is switched to the ON side contacts 7a, 8a, and 5a, respectively. In this state, for example, when either the left or right side clutch lever 2 or 3 is operated to the power off side in order to reverse the situation and perform the next reaping process, the automatic control release switch 7 or 8 will move to the OFF side contact 7b or 8.
b, thereby cutting off the circuit of the automatic direction control mechanism 6 and allowing the aircraft to rotate in a state where the automatic control is released. At this time, in the case of the present invention, the automatic control release switch 7 or 8 is
Since the OFF side contacts 7b and 8b are connected to the circuits of the direction indicator lights 9 and 10, the direction indicator light 9 or 10 on the operated side will automatically turn on, and if you are on board the moving aircraft or are in the vicinity. A very detailed warning will be given to auxiliary workers, etc. to urge them to be careful. Therefore, even if the driver does not notice, auxiliary workers in the vicinity can immediately recognize the steering status of the traveling aircraft, and can reliably prevent them from getting caught in the traveling aircraft. After the turning operation is completed, if the side clutch lever 2 or 3 is returned to the engaged state, the automatic control release switch 7 or 8 is switched to the ON side contact 7a or 8a, and the direction automatic control mechanism 6 is switched to the ON side contact 7a or 8a.
is activated, and the reaping operation is resumed under automatic direction control.

On the other hand, when steering on the road, the direction indicator light changeover switch 4 is operated to turn on the direction indicator light 9 or 10 on the side where the vehicle is turning. By the way, in the present invention, the wiring is such that power is supplied to the automatic control release switch 7 or 8 through the OFF side contact 4a of the direction indicator light changeover switch 4, so when the direction indicator light changeover switch 4 is turned on. If the automatic control release switch 7 or 8
The power supply to the side will be cut off. As a result, even if the side clutch lever 2 is disengaged, the direction indicator light 9 or 10 on the side that was disengaged will not turn on as described above, and will not turn on when the direction indicator light changeover switch 4 is turned on. Prioritize. Therefore, when steering on the road, when the vehicle turns in the opposite direction and turns in an expanded state, the direction indicator light 9 or 10 will not inadvertently turn on and issue an erroneous signal, making it safer. be.

[Function and effect]

In summary, since the present invention is constructed as described above, if you operate either the left or right side clutch lever to cut off the power while working in the field under automatic directional control, the automatic control will be canceled. When the switch is turned off, the automatic direction control is automatically canceled, and the direction indicator light on the operated side is automatically activated, giving a very detailed warning to auxiliary workers, etc. Therefore, even if the temporary driver is unaware of the existence of the auxiliary worker, the auxiliary worker can recognize the power cut operation of the side clutch and be able to prepare for the aircraft to turn around and avoid getting caught. can be reliably prevented.
The cancellation of this automatic direction control and the activation of the direction indicator light are performed by switching the automatic control release switch from ON to OFF contact based on the power cut operation of the side clutch lever. This means that it can be used for multiple purposes.

Furthermore, when driving on the road, the direction indicator light on the required side is operated by switching the direction indicator light changeover switch, but it is not possible to activate the direction indicator light on the required side by switching the direction indicator light changeover switch. The wiring structure gives priority to the operation of the direction indicator light changeover switch over the operation of the direction indicator lights, which prevents the direction indicators from erroneously operating based on the operation of the side clutch lever. Avoided and safe.
