Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to various agricultural working vehicles such as power tillers, rice transplanters, and harvesters, and more specifically to working vehicles equipped with a battery and equipped with a body cover.

[Conventional technology]

BACKGROUND ART Conventionally, in agricultural work vehicles, the on-board battery has been charged only by a charger driven by the on-board engine.

[Problem that the invention attempts to solve]

With conventional charging configurations, the aircraft is charged only when it is in use, and on the other hand, agricultural vehicles, especially tillers, etc., are not used for long periods of time, so the battery discharges during storage and the engine cannot be started when used. However, there were some problems that could not be avoided.

The purpose of the present invention is to prevent the battery from draining when the aircraft is stored, regardless of whether a cover for the aircraft is attached or not.

[Means for solving problems]

The agricultural work vehicle with a fuselage cover according to the present invention is characterized in that a solar cell for battery charging is detachably attached to the fuselage, and a hole through which the solar cell can be freely inserted is provided in the fuselage cover to attach the solar battery to the fuselage. At the same time, an attachment/detachment part for the solar cell is provided on the surface side of the fuselage cover, and its functions and effects are as follows.

[Effect]

When the aircraft is stored without a cover, the solar cells installed on the aircraft are charged in a way that prevents them from being exposed to sunlight and going into the battery.
When storing with the cover attached, remove the solar cells from the aircraft, take them outside the cover, and attach them to the cover to charge the solar cells so that they do not get exposed to sunlight and go into the battery.

Due to the cover hole and its location, the solar cell can be taken out of the cover or returned to the mounting part of the aircraft even if the solar cell and battery are connected and the connecting wire is relatively short. can.

When the aircraft is in use, the solar cells can be stored in a separate location from the aircraft, and can be attached to the aircraft to prevent them from being lost or forgotten.

[Effect of idea]

When stored, the battery will not run out regardless of whether the cover is attached or not, making it possible to start the engine without the hassle of recharging when in use, and making it convenient as it prevents the loss of solar cells when the aircraft is in use.

Moreover, when changing the mounting position of the solar cell, the charging configuration eliminates the need to separate and connect electric wires, and the electric wires can be shortened, making it possible to configure the charging configuration to be advantageous in terms of both handling and structure. did it.

〔Example〕

As shown in FIG. 1, a rotary tiller 5 is connected to the rear of a self-propelled aircraft that has wheels 1, an engine 2, a battery 3 mainly used as a power source for an engine starter 6, a control handle 4, etc. In addition, the power is transmitted from the self-propelled body to the tilling device 5, thereby forming a walking type tiller.

As shown in FIG. 3, a key-type operation switch 9 is used to operate the drive circuit 7 of the engine starter 6 and to turn on and off the power supply circuit 8 for various electric devices such as headlamps, and the battery 3 is connected to the key-operated switch 9. An open/close switch 10 is provided in between, and the open/close switch 10 is linked to the engine accelerator operating tool 11 so that it automatically opens only when the engine accelerator operating tool 11 is operated to the engine stop position. In the operated state, switch 9
Even if the user forgets to turn off the battery 3, the power is turned off and the battery 3 is prevented from discharging.

As shown in FIG. 1, a solar cell 13 is removably attached to the handle support frame 12 of the self-propelled aircraft using a hook-type fixture 21 as shown in FIG. As shown in FIG. 3, the solar cell 13 is connected to the battery 3 through an electric wire 14 and a battery charging circuit 17 between the generator 15 and the battery 3 so as to be charged therein. As shown in Figure 2, a sheet cover 1 is installed to cover the aircraft to be stored from light and to prevent rainwater from leaking.
8, a through hole 19 is formed in a location near the handle support frame portion 12 to connect the solar cell 13.
In addition, a sheet cover 20 is provided for the through hole 19, and when the cover 18 is not used during storage of the aircraft, the solar cell 13 is attached to the handle support frame 12.
When the cover 18 is installed and the cover 18 is used, as shown in FIG. In either case, a mounting tool 21 as shown in FIG.
The charging action of 3 prevents the battery 3 from running out while allowing the aircraft to be stored.

[Another example]

The solar cell mounting position of the self-propelled aircraft is not limited to the handle support frame portion 12, but may be set to the engine bonnet, etc., and these are collectively referred to as the solar cell mounting portion 12.

The mounting tool 21 on the cover side can be changed to various types with different specific configurations, such as a tape type or a band type, and these are collectively referred to as the attachment/detachment part 21.

The cover-side attaching/detaching parts for the solar cells may be distributed at a plurality of locations, and a sunny location may be selected from these locations to attach the battery.

This invention can be used not only for tillers, but also for rice transplanters, binders,
It can be applied to various agricultural vehicles such as combines.
