Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] See also Figure 1 - Figure 5 A self-unloading guidance system for an asphalt mixture transport vehicle comprises: an asphalt paver body 1, on which a signal light 2, an AI pedestrian detection camera 3, an audio speaker 4 and a millimeter-wave radar 5 are fixedly installed, and the signal light 2, the AI ​​pedestrian detection camera 3, the audio speaker 4 and the millimeter-wave radar 5 are all electrically connected to a controller on the asphalt paver body 1.

[0029] The utility model provides a self-unloading guidance system for an asphalt mixture transport vehicle. When in use, the transport vehicle is guided by the signal light 2 on the asphalt paver body 1. At the same time, the millimeter wave radar 5 cooperates with the AI ​​pedestrian detection camera 3 to measure the distance between the asphalt paver body 1 and the transport vehicle, and automatically changes the guidance color of the signal light 2 according to the measurement data. At the same time, the audio speaker 4 emits warning and guidance sounds, thereby reducing the burden on the guide personnel so that they do not need to notify the driver through gestures or shouting, and improving the reliability and safety of the guidance work.

[0033] The technical solution provided by this embodiment is: the driving mechanism 7 drives the two protective shells 6 to be close to each other, so as to protect the unused AI pedestrian detection camera 3, and prevent external dust from falling on the AI ​​pedestrian detection camera 3 when the asphalt paver body 1 is not in use;

[0034] Through the cooperation between the groove 8 and the sponge pad 9, the protective shell 6 can be completely fitted with the ceiling of the asphalt paver body 1, thereby preventing external dust from entering the protective shell 6 through the gap when the protective shell 6 is protecting.

[0035] Furthermore, the driving mechanism 7 includes a rectangular frame 71 fixedly mounted on the asphalt paver body 1, two limit rods 72 are arranged on the inner side of the rectangular frame 71, and both ends of the two limit rods 72 are fixedly connected to the rectangular frame 71, two connecting blocks 73 are arranged on the outer side walls of the two limit rods 72, and the protective shell 6 is fixedly mounted on one end of the connecting block 73, and a power mechanism 74 is arranged on the inner bottom wall of the rectangular frame 71, and the power mechanism 74 is connected to the two connecting blocks 73.

[0036] Specifically, the controller on the asphalt paver body 1 controls the power mechanism 74, so that the power mechanism 74 drives the two connecting blocks 73 on the limit rod 72 to approach each other, and then the connecting block 73 can drive the protective shell 6 to protect the AI ​​pedestrian detection camera 3.

[0037] Furthermore, the power mechanism 74 includes a motor 7401 fixedly mounted on the inner bottom wall of the rectangular frame 71 through a mounting frame, a first strip plate 7402 is fixedly mounted on the output end of the motor 7401, two round rods are fixedly mounted on the top of the first strip plate 7402, second strip plates 7403 are rotatably mounted on the connecting rods at the bottom of the two connecting blocks 73, and the other ends of the two second strip plates 7403 are rotatably connected to the round rods.

[0038] Specifically, the motor 7401 drives the first strip plate 7402 to rotate, and then the rotating first strip plate 7402 pulls the second strip plate 7403 through the round rod on its top, so that the second strip plate 7403 can drive the connecting block 73 to move under the action of the limiting rod 72 and the connecting rod, thereby preventing the protective shell 6 from protecting and opening.

[0039] Furthermore, a plurality of cushion blocks 10 are fixedly mounted in sequence in a circular array on the inner bottom wall of the rectangular frame 71 , and the motor 7401 is located on the cushion blocks 10 .
