A positioning pin 34 is installed at the bottom of the outer box 31. The bottom of the upper box cover 311 is threadedly connected to the left box 312 and the bottom of the upper box cover 311 is threadedly connected to the right box 313. A gap is provided between the opposite surfaces of the left box 312 and the right box 313. The upper box cover 311 is positioned...

[0018] Working principle: First, the drive structure is activated to transport coal conveyor belt 1 to the coal mine. At this time, the force sensor 33 on the force sensor housing 316 and the positioning pin 34 on the pin motor housing 315 are activated to sense the steel fork 2. The force signal generated when the steel fork 2 acts on the coal mine is converted into an electrical signal and transmitted to the cam motor 324. At this time, the cam motor bracket 314 is activated to make the cam motor 324 rotate the cam 323 on the rotating shaft 325, thereby causing the right push rod 321 and the left push rod 322 to swing up and down. This causes the slide rod 326 to move up and down along the left box 312 and the right box 313, thereby performing range identification of woven bags and straw. It can realize unmanned automatic identification and extraction of impurities such as woven bags and straw in coal conveyor belt 1. Example

[0019] See Figures 5-10The coal impurity conveying unit 4 includes a transmission mechanism 41, a power mechanism 42, a self-locking mechanism 43, an NFC module 44, and a limiting mechanism 45.

The power mechanism 42 includes a gear motor 421 and a gear 422. The self-locking mechanism 43 includes a slider 431, a positioning groove 432, and a slider base plate 433.

The transmission mechanism 41 is installed at the gaps in the outer casing 31, the power mechanism 42 is installed at the corners of the transmission mechanism 41, and the self-locking mechanism 43 is installed on the outside of the transmission mechanism 41. Module 44 and limiting mechanism 45 are installed inside self-locking mechanism 43; a chain conveyor belt suspension 411 is installed in the gap of the outer casing 31, and a chain conveyor belt chain 412 is threadedly connected to the bottom end of the chain conveyor belt suspension 411. A sheet metal bracket 413 is installed between the chain conveyor belt chain 412 and the chain conveyor belt suspension 411, and a wear-resistant strip 414 is installed between the sheet metal bracket 413 and the chain conveyor belt chain 412. Gear motors 421 are distributed and installed at the corner protrusions of the chain conveyor belt suspension 411. A gear 422 is installed at the bottom end of the output shaft of the gear motor 421, and one side of the gear 422 is meshed with the inner wall of the chain conveyor belt chain 412. One side of the chain conveyor belt chain 412 is symmetrical. A slider 431 is slidably connected. A positioning groove 432 is threaded onto one side of the slider 431.

The position of the steel fork 2 is sensed by the NFC module 44. At this time, the positioning groove 432 acts on the steel fork column 21, causing the short steel fork spikes 22 and long steel fork spikes 23 to move the woven bag and straw, thereby separating the woven bag and straw from the coal mine. The chain conveyor belt suspension 411 is quadrilateral in shape, facilitating its fit with the coal conveyor belt 1 and ensuring the separation of impurities in the coal mine.

[0020] After identifying the coal mine, the gear motor 421 on the chain conveyor suspension 411 is activated to rotate the gear 422, causing the chain conveyor chain 412 to move, which in turn drives the slider 431 to move. Then, the limit rod 452 on the limit rod motor 453 on the limit rod motor bracket 435 is activated to rotate, causing the locking tongue 451 to separate from the inner wall of the slider 431, thereby releasing the restriction on the steel fork 2. Then, the position of the steel fork 2 is sensed by the NFC module 44. At this time, the positioning groove 432 acts on the steel fork column 21, causing the short steel fork spike 22 and the long steel fork spike 23 to move the woven bag and straw, thereby separating the woven bag and straw from the coal mine. This realizes the automatic transportation of impurities separated in the coal impurity sorting section to the coal impurity crusher, and the circulation of the entire mechanism. Example

The impurities are crushed by the separating toothed shaft 521 and the crushing toothed shaft 522. Then, the brush motor 532 is started to make the brush 531 rotate.
