That is, the pair of front rail wheels 160 are connected to a lower end of the steering shaft 142 which is installed vertically in the steering chamber 140. Therefore, when the user turns the steering wheel 144, the rotation is transmitted to the front rail wheel 160 through the steering shaft 142 to control the traveling direction of the multipurpose electric vehicle according to the present invention.

Since the structure for controlling the direction of travel according to the steering wheel 144 operation is a configuration that is commonly used in steering devices, such as a general vehicle, further detailed description thereof will be omitted.

In the center of the outer circumferential surface of the front rail wheel 160 and the rear rail wheel 162, a rail groove 166 for receiving a rail is recessed inward. That is, since the front rail wheel 160 and the rear rail wheel 162 is configured to be rotatable on a rail, a rail groove 166 is formed along the outer circumferential surfaces of the rail wheels 160 and 162. Accordingly, since the upper end of the rail is accommodated in the rail groove 166, the multipurpose electric vehicle according to the present invention does not leave the rail during movement.

At both sides of the rail wheels 160 and 162, auxiliary wheels 170 are further installed to guide the movement of the electric vehicle on the ground and to prevent conduction. Looking more specifically, the auxiliary wheel 170 is installed outside the pair of rear rail wheels (162). That is, a pair of auxiliary wheels 170 are installed at a predetermined distance to both sides of the pair of rear end wheels 162.

The auxiliary wheel 170 is not formed with a rail groove 166, such as the rail wheels (160,162), it is made of a generally used pneumatic wheels. In addition, the outer diameter of the auxiliary wheel 170 may be the same as the outer diameter of the rear rail wheel 162, but at least larger than the outer diameter of the rear rail wheel 162 is preferably formed. The case where the outer diameter of the auxiliary wheel is larger than the rear rail wheel will be described as an example.)

As such, the reason why the auxiliary wheel 170 is formed to be greater than or equal to the size of the rear rail wheel 162 is that the auxiliary wheel 170 is used when moving the ground surface on which the rail is not installed. To do this.

In addition, the auxiliary wheel 170 is installed in a position spaced apart from the outside of the rear rail wheel 162, the multi-purpose electric vehicle according to the present invention by increasing the distance between the pair of auxiliary wheels 170 This is to prevent falling from side to side when changing direction.

The discharge chamber 190 is provided with a discharge pump and a discharge motor for generating a suction force, so that the contents inside the holder 110 is discharged to the outside. Since functions and configurations of the pump and the motor are generally used, a detailed description thereof will be omitted.

The discharge duct 200 is connected to the discharge chamber 190. The discharge duct 200 is installed to communicate with the inside of the discharge chamber 190 to guide the contents discharged by the discharge chamber 190 to the outside. That is, when the contents inside the holder 110 is forcibly discharged by the discharge chamber 190, the discharge duct 200 guides the contents.

The discharge duct 200 is made of a plastic tube of bellows type. In addition, a duct connection pipe 202 is further provided between the discharge duct 200 and the discharge chamber 190. The duct connecting pipe 202 is preferably made of a material having a high hardness, such as a metal material, the one end of the discharge duct 200 is coupled.

In addition, as described above, the storage box 110 and the steering chamber 140 are formed to be spaced apart a predetermined interval back and forth, between the storage box 110 and the steering chamber 140, a person that can enter and stay ( 210 is formed. That is, as shown, a predetermined space is formed between the storage box 110 and the steering chamber 140, the lower end of the space becomes the access end 210. Therefore, the driver enters and exits through the left and right sides of the entrance end 210, and the driver stands in the entrance end 210 or drives the seat 124.

On the other hand, the accelerator pedal 212 and the brake pedal 214 is provided on the upper side of the entrance 210. That is, the accelerator pedal 212 is provided at the upper left side of the entrance end 210, and the brake pedal 214 is provided at the right side, and the accelerator pedal 212 and the brake pedal 214 are at the front end of the steering chamber ( 140 is connected to the rear.

As described above, since the configuration and function of the accelerator pedal 212 and the brake pedal 214 are similar to those of a general vehicle, a detailed description thereof will be omitted.

Hereinafter, the operation of the multipurpose electric vehicle as described above will be described.

First, a case in which the multipurpose electric vehicle according to the present invention moves on a rail will be described. That is, a case in which a rail having a width equal to the left and right widths of the rail wheels 160 and 162 is used in a farm or an orchard is installed on the floor.

The user (driver) ascends to the access end 210 from the left or the right through the gap between the storage box 110 and the steering chamber 140. Then, the seat 124 is seated.

Next, by pressing the button of the operation unit 150, the power is turned on, and the operation unit 150 is operated to set the moving direction of the electric vehicle (for example, to set forward). Step on the accelerator pedal (212).

In this case, the power of the power chamber 180 is transmitted to the rail wheels 160 and 162 so that the rail wheels 160 and 162 rotate, and the rail wheels 160 and 162 roll on the rails. Therefore, the multi-purpose electric vehicle according to the present invention is to move forward.

Then, when it is necessary to pull up the electric vehicle, the foot is released from the accelerator pedal 212 and the foot pedal 214 is stepped on.

On the other hand, the user controls the operation unit 150, so that the discharge chamber 190 operates. In this case, the motor of the discharge chamber 190 rotates to discharge the contents inside the holder 110 to the outside.

Therefore, at this time, the user pulls out the discharge duct 200 which is inserted into the duct hanger 116, and directs the discharge duct 200 to the inside of the fishery or the fruit tree. In this case, the feed or fertilizer, etc. stored in the holder 110 is discharged through the discharge duct 200 is to be sprinkled in the fishery or orchards.

Of course, when the feed or fertilizer, etc. in the holder 110, peel off the storage cover 114 of the storage box 110 to work upwards, or peel off only the simple cover 122 upwards (Feed or fertilizer, etc.) may be introduced into the storage box (110).

As described above, the operation of discharging the feed or fertilizer through the discharge duct 200 is possible, of course, even when the multi-purpose electric vehicle according to the present invention is stopped.

On the contrary, when the operation direction of the electric vehicle is set to reverse in the operation unit 150 and the accelerator pedal 212 is pressed, the electric vehicle according to the present invention will move rearward along a rail.

On the other hand, the case where the electric vehicle by this invention moves the general ground surface in which the rail is not provided is demonstrated. Of course, even in this case, the operation process of the multi-purpose electric vehicle according to the present invention is similar to that described above.

However, in this case, the user will have to control the continuing direction by using the steering wheel 144. In this case, the auxiliary wheel 170 replaces the rear rail wheel 162. That is, since the outer diameter of the auxiliary wheel 170 is larger than the outer diameter of the rear rail wheel 162, only the auxiliary wheel 170 is in contact with the ground surface, the rear rail wheel 162 is not in contact with the ground surface It will not be.

As such, when the auxiliary wheel 170 touches the ground surface, the electric vehicle can be stably operated relatively compared to the case where the rear rail wheel 162 touches the ground surface. This is because the distance of the pair of auxiliary wheels 170 is greater than the distance between the pair of rear rail wheels 162.

As described above, the multi-purpose electric vehicle according to the present invention can be easily moved not only in a place where a rail is installed, but also on a general ground surface.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

For example, the above embodiment illustrates a case in which the feeder of fish or fertilizer sprayed on an orchard is spread and sprayed in the storage box 110, but the storage box 110 includes pesticides in addition to these contents. Of course, the same other contents can be stored and used.

In addition, the multi-purpose electric vehicle according to the present invention can be used when catching fish or harvesting fruit trees. That is, in the case of catching fish, the holder 110 is used for storing the captured fish, and is used for the storage of the fruit when harvesting the fruit.
