[0057] Step S5: After the conveyor belt starts, the strip scrapers in the scraping structure scrape the adhesive on the conveyor belt, and the scraped adhesive falls onto the receiving plate;

[0058] Step S6: Start the driving assembly in the cleaning structure, and the driving motor in the driving assembly drives the gear transmission on the second rotating shaft, so that the gear drives the transmission chain to rotate, thereby driving the cleaning scraper in the cleaning structure to sweep the adhesives dropped from the receiving plate into the receiving structure.

[0059] The utility model also includes a conveying system, which includes a mineral hopper 1. The mineral hopper 1 is provided with a screen device and a vibration mechanism for facilitating feeding.

[0082] When the ore falls onto the conveyor belt 42, the conveyor belt 42 squeezes the first receiving block 46 and the second receiving block 47 due to pressure, thereby squeezing the connecting rod 45, thereby squeezing the cross bar 44, and then squeezing the third return spring 411, playing a buffering role.

[0083] The guide buffer assembly 48 includes a buffer groove 481, which cooperates with the buffer groove 481, the telescopic block 483, and the fourth return spring 482 to play a buffering role when the mineral material falls onto the conveyor belt 42; a plurality of buffer grooves 481 are provided on the top surface of the first material receiving block 46, and the telescopic block 483 is connected to the buffer groove 481 via the fourth return spring 482.
