9. The hair scraping device for slaughtering black pigs according to claim 1, characterized in that: The liquid collecting box structure (3) comprises a liquid outlet pipe (302) fixedly arranged at the lower side of the shaving cylinder (2); the lower end of the liquid outlet pipe (302) is detachably connected to a filter box (303); a filter screen (306) is arranged at the bottom of the filter box (303); a handle (305) is fixedly arranged on the outer side of the filter box (303); a liquid collecting box (301) is arranged on the base (1) below the filter box (303); and a drainage pipe (304) is arranged on one side of the bottom of the liquid collecting box (301).

10. A method for scraping hair for slaughtering black pigs, characterized in that: The black pig slaughtering scraping device according to any one of claims 1 to 9 comprises the following steps: S1: The pig body is fed from the pig inlet bucket (203) into the hair scraping cylinder (2), and the rolling drive assembly (6) drives the flipping hair scraping roller (8) and the driving hair scraping roller (9) to rotate synchronously in the same direction, thereby driving the pig body to move along the direction from the pig inlet bucket (203) to the pig outlet (202), and also driving the pig body to flip and rotate; S2: In step S1, the first scraper (801) disposed on the outer side of the flipping scraper roller (8) can not only move and flip the pig body, but also scrape the pig body during the contact with the pig body; S3: In step S1, during the rotation of the driven shaving roller (9), the spiral ribs (901) can drive the pig body to move along the axial direction of the driven shaving roller (9), and the second shaving blade (904) can perform a shaving operation on the pig body, and during the shaving operation of the second shaving blade (904) on the pig body, the elastic hanging rope (902) can achieve elastic contact between the second shaving blade (904) and the pig body; S4: a color image identifier (11) is arranged inside the shaving tube (2) at the pig outlet (202). The places where the shaving of black pigs is omitted are black, so as to identify whether the shaving operation is completed. After the shaving is completed, the pig body is discharged from the pig outlet (202); S5: The cleaning mechanism (5) cooperates with the cleaning component (7) to wash the fluff on the pig body and the scraped pig hair, and the pig hair and the waste liquid generated by the cleaning are filtered and separated at the liquid collecting box structure (3); S6: When a blockage occurs during the process of the flipping scraping roller (8) and the driving scraping roller (9) driving the pig body to flip and feed, the rotating drive assembly (4) drives the scraping roller (2) to flip ninety degrees so that the side opening (204) is set downward, and then the rolling drive assembly (6) drives the flipping scraping roller (8) and the driving scraping roller (9) to rotate in the opposite direction to clear the blockage.
