[0026] Embodiment 1

[0027] As Figures 1 to 4As shown, a scraper structure for a centrifuge comprises an annular base 1. The upper surface of the base 1 is provided with a plurality of annular grooves 11 extending from the outside inward, which mate with the lower end of the discharge pipe 5. First screw holes 12 are provided on the outer surfaces of the left and right sides of the fixing base 1, extending inward through the annular grooves 11. First bolts 3 are screwed inwardly through the first screw holes 12. Circular fixing blocks 14 are fixed to the front and rear sides of the center hole of the base 1, respectively. Vertical through-holes 13 are provided on the fixing blocks 14 and the bottom surfaces of the outer (front and rear) annular grooves 11. Sliding scrapers 4 (only the innermost set is shown) are inserted into the front and rear pairs of through-holes 13.

[0028] The scraper 4 includes a scraper 41 with an arc-shaped top, and a connecting block 42 is provided on the inner side of the scraper 41. The connecting block 42 passes through downward and is screwed with a second bolt 43. The second bolt 43 is threadedly connected to the top of the vertical slide rod 44, and the top of the slide rod 44 is embedded with a second screw hole 441 that cooperates with the second bolt 43.

[0029] A transverse screw sleeve 2 is fixedly provided on the base 1 at the outer end of the first screw hole 12 , and the screw sleeve 2 is concentrically arranged with the first screw hole 12 .

[0030] Pull rings 45 are fixedly provided at the bottom of the slide rods 44 .

[0031] The diameter of the through hole 13 is larger than the outer diameter of the slide bar 44 so that the slide bar 44 can swing at multiple angles, which is beneficial to scraping the material off the inner wall of the feed pipe 5.

[0032] During use, the provision of several annular grooves 11 facilitates matching with the lower ends of feed tubes 5 of varying diameters, thus expanding its scope of application. The first bolt 3 can be screwed inward from the outside to tighten the feed tube 5, preventing the base 1 from slipping. The slide bar 44 can pass through the through-hole 13 from the bottom up, and a scraper 41 can be mounted on the top via a second bolt 43. The scraper 41 is available in a variety of models, selected based on the type of feed tube 5. The front and rear sets of scrapers 41, in conjunction with the vertically sliding slide bar 44 (which can slide together or separately), can scrape downwardly the material inside the feed tube 5. The sleeve 2 cooperates with the first bolt 3 to ensure the secure attachment of the outermost annular groove 11 to the feed tube 5. The pull ring 45 facilitates gripping by the operator, facilitating the downward pulling of the slide bar 44.

[0033] Example 2
