[0002] As an important conveying equipment in national production and life, belt conveyors are widely used in many industries, such as grain transportation and tobacco transportation. Because the conveyed materials sometimes adhere to the belt, as the belt moves, these adhered materials will fall off when the belt rotates. Therefore, technicians usually design a bottom plate under the belt conveyor to receive these fallen materials to avoid contaminating the production workshop. However, as time goes by, these materials will continue to accumulate on the surface of the bottom plate. If they are not cleaned in time, the bottom plate will be covered with materials, or even piled up too high and affect the normal operation of the belt. In this regard, manual methods are usually used to clean the materials accumulated on the surface of the bottom plate. However, for belt conveyors installed at high places, relying solely on manpower to clean is not only time-consuming but also dangerous.

At this time, the robot body 6 still follows The extension of the longitudinal color band continues to move toward the tail end of the bottom plate 2 until the grayscale sensor C17 and the grayscale sensor D18 detect the grayscale value of the transverse color band to feedback the signal to the single-chip controller 21, and the single-chip controller 21 immediately sends a signal to the motor drive board 20 that can reverse the drive motor 8, thereby controlling the robot body 6 to return; during the period when the robot body 6 drives the cleaning brush to return, the rear brush 13 in contact with the surface of the bottom plate 2 pushes the material that falls on the surface of the bottom plate 2 again from the tail end of the bottom plate 2 to the head end of the bottom plate 2, so that the material concentrated on the side end face of the rear brush 13 away from the robot body 6 is pushed to the head end of the bottom plate 2 and collected in the collecting trough, until the grayscale sensor C17 and the grayscale sensor D18 detect the grayscale value of the transverse color band again to feedback the signal to the single-chip controller 21, and the single-chip controller 21 controls the robot body 6 to return again. After all times are executed, the cleaning and scraping of the fallen material on the surface of the bottom plate 2 are completed;

[0057] Step S3: Cleaning the Aggregate Hopper 4
