[Detailed Description of the Invention] Industrial field of application The present invention relates to a mobile agricultural machine equipped with a solar cell for charging a battery.

-Prior Art As an agricultural work machine equipped with a solar cell as a natural discharge of a battery, an "agricultural work machine" disclosed in Japanese Utility Model Laid-Open No. 61-25048 is known.

○ Problems to be solved by the present invention In the above-mentioned known technology, the solar cell is connected to the top surface of the hood of the mobile agricultural machine, so that the solar cell may be damaged during agricultural work or during storage.

○ Means for solving the above problems In the present invention, an opening / closing cover 8 is provided on the upper part of the machine, a solar cell 10 is provided inside the opening / closing cover 8, and the opening / closing of the opening / closing cover 8 is linked. A switch 22 is provided, and the cover open contact of the switch 22 is connected to the solar cell 10 via the diode 12.
, And the cover closing contact of the switch 22 is connected to the first relay 23. The first relay 23 controls the ignition circuit of the engine to the operating state in the relay operating state and opens the openable cover 8 to open the sun. The solar battery 10 is disconnected from the battery 11 by connecting the battery 10 to the battery 11, stopping the engine, and closing the openable cover 8, and the ignition circuit of the engine is controlled to the operating state to bring the engine into the operating state. Configure to be maintained.

○ Example Shows a case where the present invention is applied to a cultivator as a mobile agricultural machine,
The present invention will be described in detail based on the illustrated embodiment.

2 and 3, 1 is an engine, 2 is a transmission case, 3 is a handle base, 4 is a handle, 5 is a tiller, 6 is a traveling wheel, 7 is a chassis, and 11 is a battery.

A solar cell 10 is attached above the engine 1, and an openable cover 8 is provided above it.

The openable cover 8 can also be used as a bonnet, and the solar cell 10 can be attached to the engine 1 or an appropriate place of the vehicle through an appropriate attachment plate located below the hood.
The solar cell may be fixed to the top surface of the bonnet and the openable cover 8 may be provided above the bonnet.

Next, the electric circuit of the mobile agricultural machine equipped with the solar cell 10 will be described with reference to the circuit diagram of FIG.

At the "OFF" position of the key switch 9 (that is, the engine is stopped by operating the key switch), the key terminal B and the key terminal A are set to be in a short-circuit state, and the battery B is connected to the terminal B via the fuse F. Then, the solar cell 10 is connected to the terminal A via the backflow prevention diode 12. 13 is a starting circuit.

When working, keep the openable cover 8 in the horizontal position and
Protect the top surface of 10.

When the engine 1 is stopped during work suspension, the key switch 9 is set to the “off” position, the openable cover 8 is opened, and the upper surface of the solar cell 10 is exposed. The solar cell 10 starts operating due to the incidence of sunlight on the battery 11, and the battery 11 is charged by the solar cell 10.

Next, in the second embodiment shown in FIG. 4, the engine is stopped even at the start position of the key switch and the solar battery can charge the battery.

Next, referring to FIG. 4 showing an embodiment of the present invention, a switch which is interlocked with the opening and closing of the openable cover (bonnet) 8 between the power supply terminals B and B ′ of the key switch 9 and the diode 12.
22 and a cover opening contact of the switch 22 is a diode.
12 and the cover closing contact is connected to the first relay 23,
A short circuit 25 for the ignition coil 24 of the ignition circuit is provided, and a relay contact 26 of the second relay 27 is provided in the short circuit 25, and the first relay is provided between the IG terminal of the key switch 9 and the ground.
23 relay contacts 28 are connected in series.

In the normal state in which the openable cover 8 is closed, the relay contact 28 of the first relay 23 is closed, the relay contact 27 of the second relay 27 is open, the short circuit 25 does not operate, the engine is ignited, and the operating state ， The operating condition is maintained.

By opening the openable cover 8 and setting the switch 22 to the closed position, the solar cell 10 charges the battery 11, and the first relay 23 and the second relay 27 operate to stop the engine.

Although the above is the engine stop mechanism for an electric circuit of gasoline specification, in the case of a diesel engine, the object of the present invention can be achieved by configuring the fuel supply motor to be stopped at the cover open position of the switch 22. You can

FIG. 5 shows a battery mounting structure, in which a battery 11 is installed in an appropriate place of the machine body (for example, a space between the engine 1 side surface and the transmission case 2 above the hood and above the chassis 7). The pedestal 14 is provided, the lower end of the battery first fastening bolt 15 is fixed to one end of the battery pedestal 14, and the lower end of the second fastening bolt 16 is opposed to the fastening bolt 15 to the battery pedestal 14. It is locked so that the upper side of the second tightening bolt 16 is rotatable.

By inserting the washer 18 and the nut 19 by penetrating the upper ends of both tightening bolts 15 and 16 through the battery tightening metal fitting 17, the battery tightening metal fitting 17 and the battery 11 are attached via both mounting bolts 15 and 16.
Can be fixed to the battery pedestal 14 freely. In addition, 20 is a cushioning rubber inserted in both tightening bolts 15 and 16.

In place of the through holes for penetrating the both tightening bolts 15 and 16, the battery tightening metal fitting 17 is provided with notched holes 21 and 21 arranged in an inverted C shape shown in FIG. As shown in Fig. 1, one side is a round hole 21 'and the other side is a cutout hole 21.

Due to the presence of the cutout hole 21, when the battery 11 is removed, the nut 19 is slightly loosened to rotate the first tightening bolt 15 forward along the cutout hole 21. The first tightening bolt 15 can be removed, and all nuts can be used for battery maintenance.
It is not necessary to rotate 19 to remove the battery 11, and the battery 11 can be easily removed.

○ Effect of the invention The invention is that the battery is charged by the operation of the solar cell by opening the openable cover in the operation stop state, so there is no concern about the power supply voltage decreasing due to the natural discharge of the battery, and the engine is always restarted. Is effective.

Further, since the solar cell is retractable inside the openable cover, there is no risk of damage to the solar cell during work or storage of the machine body.

Further, a switch 22 that interlocks with the opening / closing of the open / close type cover 8 is provided, the cover open contact of the switch 22 is connected to the solar cell 10 via the diode 12, and the cover close contact of the switch 22 is in the operating state of the engine ignition circuit. Since it is connected to the first relay 23 which is controlled to, the opening / closing cover 8 is closed to control the ignition circuit of the engine to an operating state to maintain the engine in an operating state, and the opening / closing cover 8 is surely opened. By stopping the mobile agricultural machine, there is an effect that the traveling of the mobile agricultural machine with the openable cover 8 opened can be reliably prevented. In particular, when the bonnet is applied as the openable cover, it has the effects of protecting the engine, the storage battery and other devices with the bonnet during work and running and enhancing the safety of running and working.
