The rear side surface of the feed box 427 is fixedly connected to the front side surface of the frame 312.

[0028] Furthermore, the present embodiment utilizes the motor 412 in the rotating part 41 through the rotating mechanism 4.

As the worm wheel 415 rotates, it drives the light rod 421 connected thereto to rotate synchronously. The rotation of the light rod 421 then drives the rotation of the rotating plate 422. The rotating plate 422 serves as a platform for carrying key components such as the motor 5 423, the U-shaped plate 424, the spraying machine arm 425, the spray gun 426 and the feed box 427.

[0029] When in use, the vehicle body is placed in the gantry frame 1, and the longitudinal walking mechanism 2 is used to utilize the motor 212 in the longitudinal walking part 21. The motor 212 drives the reciprocating threaded rod 213 to rotate. As the reciprocating threaded rod 213 rotates, the threaded plate 214 matched therewith is pushed by the thread to perform linear reciprocating movement. The movement of the threaded plate 214 further drives the moving plate 215, so that the moving plate 215 and the transverse walking part 22 thereon move as a whole along the longitudinal direction until reaching the predetermined spraying position.

After 22 is accurately positioned to the required position, the second motor 221 starts to work, and the second motor 221 drives the two-way threaded rod 222 to rotate. The two-way threaded rod 222 drives the two threaded blocks 223 thereon to move simultaneously. The two threaded blocks 223 are respectively connected to the door plate 224, the lifting mechanism 3 and the rotating mechanism 4. Therefore, with the movement of the threaded block 223, the door plate 224 and the lifting mechanism 3 and the rotating mechanism 4 thereon also move horizontally, thereby realizing the precise adjustment of the spraying device in the horizontal direction. After adjustment, through the lifting mechanism 3, using the driving part 31 The motor 311 of the present invention is a motor 311. When the motor 311 receives the start signal, it starts to rotate and drives the reciprocating screw rod 313 to rotate synchronously. When the reciprocating screw rod 313 rotates, it drives the threaded block 314 to move back and forth along its axis. As the threaded block 314 moves, it further drives the lifting plate 321 to move up and down. As the lifting plate 321 moves, the lifting plate 321 slides on the surface of the sliding rod 323 under the action of the sliding plate 322, so that the lifting plate 321 can adjust the height of the rotating mechanism 4 and the spraying device thereon, thereby adjusting the height of the rotating mechanism 4 and the spraying device thereon by rotating. The rotating mechanism 4 utilizes the motor 412 in the rotating part 41. The motor 412 drives the worm 413, so that the worm 413 engages with the worm wheel 415, so that the worm wheel 415 drives the light rod 421, so that the light rod 421 drives the rotating plate 422, so that the rotating plate 422 drives the motor 5 423, the U-shaped plate 424, the spraying machine arm 425, the spray gun 426, and the feed box 427 to adjust the overall position, thereby driving the motor 5 423, so that the motor 5 423 rotates the spraying machine arm 425 as a whole, thereby facilitating the spraying of different positions and angles of the vehicle body.
