The driving unit 230 may be formed by connecting the battery 231 and the DC motor 232, for example.

The battery 231 may be used, for example, a battery having a relatively long life and easily purchased.

The battery 231 may be in a form that can be charged using an external power source. When using an alternating current such as a home power source as a power source, a converter for converting the alternating current into a direct current may be provided together.

Such a battery mainly provides a low voltage of about 12V, and together with a small DC motor operating at such a low voltage, the driver 230 becomes smaller.

As a method for changing the rotation direction of the DC motor 232, for example, a two-circuit two-contact switch or a two-circuit two-contact relay is used. Use this to selectively change the power supply's + and-.

A power transmission device is provided to transmit the rotation of the DC motor 232 to the wheel.

The power train may be composed of a chain 233 and a sprocket 234 as shown, for example, a power from a long distance, such as a combination of a belt and a pulley or gear. Various forms of delivery are possible.

Referring to the drawings, the guide wheel 240 is disposed one each in front and rear of the frame 210.

Through this, the load of the frame 210 and the carrying object may be supported by the at least two wheels 220 and the at least two guide wheels 240.

The switch 260 for controlling the operation of stopping the rotation of the wheel 220 in contact with the stop inductor 150 (refer to FIG. 1) is preferably mounted on both front and rear ends of the frame 210. This allows the switch 260 to operate as a safety device at all times regardless of the direction in which the wheel 220 rolls.

In the frame 210, a control switch 260 ′ may be formed to control an operation of causing the wheel 220 to rotate by the driving unit 230. For example, the control switch 260 ′ may be configured to rotate the wheel 220 when pressed once, and to stop the wheel 220 when pressed again.

4 is an enlarged view illustrating part IV of FIG. 3.

The outer circumferential surface of the guide wheel 240 is formed in a cross section provided with a groove 241 for receiving the track 150 (see FIG. 1).

The groove 241 is formed, for example, as a letter 'U' or 'V' to prevent the guide wheel 240 from deviating laterally on the silver track 150.

The guide wheel 240 is reversibly connected to the frame 210 to be aligned with the direction of the track 150.

This allows the conveying machine 200 to proceed smoothly along the curved orbit 150.

The guide wheel 240 is mounted to the guide wheel support 242 to rotate about a central axis (not shown). Guide wheel support 242 is formed in a plate bent form one side is rotatably fastened to the guide wheel support member (243). For example, a hole corresponding to each other may be formed on one surface of the guide wheel support 242 and the guide wheel support member 243, and the holes may be connected by loose rivet joints 142 ′ (see FIG. 1).

In order to alleviate or prevent the departure of the guide wheel 240 and the track 150, the frame 210 may be equipped with at least one pressing portion 270 for pressing the guide wheel 240 toward the track 150. have.

The pressing unit 270 may be configured by coupling the guide wheel support member 243 and the spring 271 and the like.

One end 244 of the guide wheel support member forms a frame 210 and a hinge coupler 272, and the other end 245 is equipped with a guide wheel support 242.

One end 244 of the guide wheel support member is connected to a spring 271.

The spring 271 is connected to the spring support rod 274, and the spring support rod 274 may be coupled to adjust the amount of deformation of the spring 271 and the coupler 275 provided in the frame 210. For example, a male screw may be formed on the outer circumferential surface of the spring support bar 274 and a female screw may be formed on the coupler 275 to be coupled.

This coupling is adjusted according to the degree of rotation of the spring support rod 274, the length of the spring support rod 274 protrudes through the coupler 275. At this time, as the length of the spring support rod 274 protrudes, the tensile strain of the spring 271 becomes larger, thereby adjusting the elastic force of the spring 271.

The elastic force of the spring 271 pulls the one end portion 244 of the guide wheel support member, and the other end portion 245 of the guide wheel support member, like a seesaw, moves away from the hinge coupler 272. Will rotate.

The guide wheel support 242 mounted on the other end 245 of the guide wheel support member rotates in a direction away from the hinge coupling portion, and the guide wheel 240 is pressed toward the track 150.

In general, a track (or rail) for guiding a traveling direction of a monorail or a train forms a plurality of tracks. Unlike this, even when the track 150 is formed as a single track (see FIG. 1), the departure of the guide wheel 240 through the pressing unit 270 may be alleviated or prevented. In addition, since the departure of the guide wheel 240 may be alleviated or prevented through the pressing unit 270, the track 150 may be simply installed by connecting a pipe or the like.

5 is a conceptual diagram illustrating a pressing unit 370 according to another embodiment of the present invention.

Guide wheel support member 343 is coupled to be fixed to the frame (310).

A hole 346 is formed in one surface of the guide wheel support member 343. The guide wheel pedestal 342 is formed with a protrusion 342a which is inserted into the hole 346 and is movable through the hole 346. An end of the protrusion 342a is provided with a departure preventing part 342b formed to be larger than the hole 346 so that the protrusion 342a does not completely leave the hole 346.

A spring 371 is disposed to wind the outer circumferential surface of the protrusion 342a to pressurize the guide wheel 240.

The spring 371 is compressed by the weight of the frame 310 and the like, and the elastic restoring force that presses the guide wheel 240 to the track 150.

Such a pressing part may be configured without a spring 371. For example, a magnet or the like may be used to use the magnetic force, or the guide wheel 240 may be pressed onto the track 150 using gravity using the protrusion 342a as a very heavy object.

6 is a conceptual diagram illustrating a farmland transporting machine 400 according to another embodiment of the present invention.

The differential gear unit 480 is mainly used for driving the rear axle of a vehicle, and is generally composed of a ring gear, a differential pinion gear 482, a differential side gear 483, and the like, which receive driving force.

Referring to FIG. 6, a sprocket 481 serving as a ring gear is formed, and a chain 433 is connected to the sprocket 481 for transmitting the rotational force of the motor.

Instead of the sprocket 481, a variety of configurations are possible, such as using a gear and receiving the rotational force of the motor by a combination of gears.

A differential side gear 483 is connected to the wheel shaft 421. When the sprocket 481 rotates by the rotation of the chain 433, the sprocket 481, the differential pinion gear 482, and the differential side gear 483 rotate together with the wheel shaft 421.

If the rotational resistance applied to both wheels 420 is different, the differential pinion gear 482 meshes with the differential side gear 483 to rotate. Through this, the differential pinion gear 482 rotates as the number of revolutions of one wheel decreases to increase the other wheels.

The differential gear unit 480 allows the left and right wheels 420 to be differentially rotated when the track 150 is bent so that the transport machine 400 smoothly proceeds along the track.
