By providing a baffle 12, mud and water can be prevented from splashing into the vehicle body 1 due to the rotation of the wheels 8 when the device as a whole is traveling in the field. By providing the turn signals 13 and the display screen 14, it can be shown that the transport vehicle as a whole is about to turn, or that it is in a drug spraying state, so as to remind people around to stay away, which is beneficial to improving the overall safety of the present invention.

[0037] The method for using the multifunctional remote-controlled transport vehicle comprises the following steps: S1, loading crops through the transport box 2, using an external controller, driving the drive motor 301 in the adjustable four-wheel drive component 3 through the remote control system 5, driving the transport vehicle to move, transporting the crops, and driving the spraying pump 406 in the spraying component 4 to evenly spray the medicine stored therein to the field through the first spray pipe 404 and the second spray pipe 405; S2, by controlling the electric push rod 409 or the first rotary motor 410, the first nozzle 404 is adjusted in lateral angle or vertical rotation, and by controlling the second rotary motor 4221, the second nozzle 405 is adjusted in vertical rotation; S3. When the transport vehicle is in a stationary state, the nut 3054 is rotated to move the bolt 3052 up and down along the position of the fixing plate 3051 , thereby driving the ring 3053 and the wheel shaft 801 to move up and down to adjust the tension of the chain 303 . Practical application cases

[0038] The harvested crops are placed in the transport box 2, and a signal is sent to the remote control system 5 through the controller to start the drive motor 301, and the driven gear 304 is driven by the transmission gear 302 in combination with the chain 303, so that the transport vehicle is driven to move as a whole through the four-wheel drive mode; When the transport vehicle is moving, the controller is used to control the spraying pump 406 to start, and the stored medicine is sprayed to the field through the first nozzle 404 and the second nozzle 405. When spraying, the electric push rod 409 can be controlled to extend to expand the first nozzle 404 to expand the spraying angle, or the first rotating motor 410 can be controlled to start to vertically rotate and adjust the spraying angle of the first nozzle 404, or the second rotating motor 4221 can be controlled to start to vertically rotate and adjust the second nozzle 405. When the transport vehicle is moving or spraying medicine, the working status of the transport vehicle can be displayed through the turn signal 13 and the display screen 14 to remind people around to stay away; When the transport vehicle stops running, the nuts 3054 on both sides of the wheel frame 101 are synchronously rotated to move the bolts 3052 up and down, and the rings 3053 are driven to move synchronously, so that the wheel axle 801 moves up and down to adjust the tension of the chain 303 and maintain the stability of the transport vehicle during operation.
