This invention discloses a belt anti-scratch system and method for a belt sampling machine. The system includes a support frame, a protective cover, and a main controller. The support frame is mounted on the belt conveyor frame, with the protective cover connected to its upper part. Industrial cameras are installed inside the protective cover and at the bottom of the belt for real-time monitoring of the belt's condition. A rotating support is mounted on the support frame, with a rotating shaft passing through the protective cover. One end of the shaft is connected to a reducer and a motor, while the other end holds a sampling head placed inside the protective cover, forming a rotatable sampling structure. The main controller is electrically connected to the industrial cameras and the motor. It acquires belt image data through the industrial cameras, processes the data, and then controls the motor to drive the sampling head, achieving monitoring of the belt's operating status and anti-scratch control during the sampling process. Through structural integration and intelligent control, this system effectively prevents the sampling head from scratching the belt, improving the safety and reliability of equipment operation.

This invention discloses an additive manufacturing-based inertial amplification nonlinear low-frequency vibration isolation metamaterial structure, vibration isolation device, and its performance control method. The vibration isolation metamaterial structure includes a rhombic frame structure, an inertial amplification unit, and a square spring structure. The square spring structure is arranged within the rhombic frame structure, with its two ends connected to a pair of opposite corners of the rhombic frame structure. The elastic extension direction of the square spring structure is parallel to the diagonal of this pair of opposite corners of the rhombic frame structure. The inertial amplification unit has a centrally symmetrical structure, including a rigid rod, two counterweights, and two diagonal rods. The center of symmetry of the inertial amplification unit, the center of the rhombic frame structure, and the center of the square spring structure all coincide in projection. Therefore, the vibration isolation metamaterial structure of this invention significantly widens the bandgap range and enhances low-frequency vibration isolation performance, exhibiting excellent performance in suppressing longitudinal waves in the 0-1000Hz low-frequency range, increasing vibration damping, and energy absorption.

This utility model discloses a protective steel wire rope. This protective steel wire rope aims to solve the technical problem of existing technologies that use rubber, nylon, or metal braided layers to wrap steel wire ropes. While these provide some mechanical protection, the sheaths are usually fixed and non-extensible, affecting the flexibility and dynamic performance of the steel wire rope. The protective steel wire rope includes a wire feeding box, with a drive motor bolted to one end. A feeding roller is installed at the output end of the drive motor. Through a telescopic protective tube employing a first telescopic protective layer, a second telescopic protective layer, a third telescopic protective layer, and a circular protective steel ring, it can extend or retract synchronously with the raising and lowering of the steel wire rope. This avoids the rigid constraints of traditional fixed sheaths or the jamming problems of segmented protective covers, preventing the intrusion of external dust, moisture, and corrosive media, reducing rust and wear of the steel wire rope, and exhibiting good impact resistance, cut resistance, and wear resistance.
