[Industrial applications]

 The present invention relates to an electric spray car.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, an electric motor-driven self-propelled spray car that travels back and forth between ridges in a field has been used for watering, spraying chemicals, and the like in cultivation of vegetables and the like. In such a conventional spray car, electric power from a charged battery drives a motor to rotate wheels to drive the spray car.

[0003]

[Problems to be solved by the device]

 In the conventional spray car as described above, the battery must be charged for a long time (for example, about 8 hours) after every 4 hours of continuous work due to the capacity of the battery. It was inconvenient because one day's work (8 hours' work) could not be performed continuously, a spare battery was required, and replacement of the battery was time-consuming.

[0004]

[Means for Solving the Problems]

 The present invention is characterized in that an electric spray car having an electric motor for driving wheels is provided with an engine generator for charging a battery electrically connected to the electric motor.

【Example】

 Next, the present invention will be described with reference to the drawings. Fig. 1 is a side view schematically showing a power generation type electric spray car that automatically reciprocates along a ridge between adjacent ridges in a field and sprays water or chemicals on surrounding crops. It is partially cut away to show various devices arranged inside the fuselage 1. This power generation type electric spray car has a pair of wheels 3 and 4 mounted on both sides of a front part and a rear part of a vehicle body 2. These wheels 3 and 4 are an electric motor 5 mounted on the vehicle body 2. It is mechanically connected by a chain transmission 12 or the like, and is rotationally driven by the driving force of the electric motor 5.

Further, a small battery 6, an engine generator 7 driven by an air-cooled 4-cycle gasoline engine and the like, a hose reel 8 and the like are provided in the body 1 on the vehicle body 2. The small battery 6 is electrically connected to the electric motor 5 by a connecting wire 9 via a control unit (not shown) for controlling rotation direction switching, and the engine generator 7 has its power output end. The small battery 6 is electrically connected by a connecting line 10 via a charging unit (not shown). The engine generator 7 is of a normal type in which the engine drives the generator to generate electric power more than the electric power required by the electric motor 5. As long as there is fuel in the fuel tank, or the fuel is replenished. If so, long-term continuous operation is possible. Therefore, during the operation of the engine generator 7, the electric motor 5 is driven by the electric power from the engine generator 7, and the surplus electric power is stored in the small battery 6. Further, the control unit can be operated by an appropriate switch operation to easily stop and reverse the electric motor 5. Further, the small battery 6 can drive the electric motor 5 as a standby power source when the engine generator 7 is stopped, and is always maintained in a charged state by the electric power from the engine generator 7 during the operation. .

The hose reel 8 is rotatably attached to the vehicle body 2, and the hose 11 is wound many times. The outer end of the hose 11 extends outwardly from the machine body 1 and is connected to a pump (not shown) installed at one end of the ridge. The pump is adapted to pump up the spray liquid from a container containing the spray liquid such as water or chemicals, and pump the spray liquid to the hose 11. Further, the inner end of the hose 11 is connected to a spray nozzle device (not shown) provided on the vehicle body 2, and the spray liquid pumped into the hose 11 is passed through the spray nozzle device to the electric sprayer. Can be applied to surrounding crops. In addition, the hose reel 8 is drivingly connected to the axles of the wheels 3 and 4 by a belt and pulley drive device (not shown), and the hose 11 is paid out or wound up from the hose reel 8 according to the traveling of the electric spray car. In addition, the hose reel 8 is adapted to rotate.

[Effect of the device]

 With the configuration described above, the present invention does not normally require battery charging, enables long-term continuous operation, enhances work efficiency, and controls the operation, stop, and reverse rotation of a self-propelled spray car with a switch operation. In addition, even if the engine stops, it is possible to work with the power from the battery for the time being, and the self-propelled spray car can be easily moved after the engine is stopped. It can be used as a power source and has many common parts with the conventional battery-powered self-propelled spray car, which is economically superior.
