Abstract

A scraping and cleaning device (1) for conveyor belts (N) comprising a support shaft (15) arranged transversally to the belt (N), one or more frames (3) being arranged on said shaft (15), each frame being provided with scraping members (4) adhering with the surface (S) to be scraped of said belt (N), to define on it at least a contact line (5). The device comprises adjusting means (6, 10, 17) adapted to vary in a significant way the position of the contact line (5).

Claims

1. ) A scraping and cleaning device (1) for conveyor belts (N) comprising a support shaft (15) arranged transversally to said belt (N) on which one or more frames (3) are applied, each of said frames being provided with scraping members (4) adhering to the surface (S) to be scraped of said belt (N) to define on it at least a contact line (5), characterized by being provided with adjusting means (6,10, 70) adapted to vary in a significant way the position of said contact line (5).

2. ) The device (1) according to claim 1 characterized in that said adjusting means (6) comprise a plurality of through holes (7) made in each of said one or more frames (3), adapted to receive fastening means (8) of said frames (3) to said shaft (15).

3. ) The device (1) according to claim 1 characterized in that said adjusting means (6) comprise at least a through slot (9) made in each of said one or more frames (3), adapted to receive one or more fastening means (8) for said frames (3) to said shaft (15).

4. ) The device (1) according to claim 3 or 4 characterized in that said fastening means are screws or bolts.

5. ) The device (1) according to any of the preceding claims characterized in that said adjusting means (10) comprise at least a first guide (11) to which a first saddle (12) is slidingly coupled, supporting a second guide (13) on which at least a second saddle (14) supporting said shaft (15) is moving, said guides (11, 13) being adapted to define two mutually incident translation directions (X, Y) for said saddles (12, 14).

6. ) The device according to claim 5 characterized in that said translation directions (X, Y) are mutually orthogonal, the one (X) being generally parallel to the advancement direction (A) of said belt (N) and the other (Y) being generally orthogonal to the surface (S) of said belt (N).

7. ) The device (1) according to any of claims 5 or 6 characterized in that said saddles (12, 14) are provided with elements (17) blocking their sliding movement in said guides (11, 13).

8. ) The device (1) according to any of the preceding claims characterized in that elastic elements (20) are interposed between said frames (3) and said shaft (15), adapted to make a yielding contrast of said scraping members (4) against the surface (S) of said conveyor belt (N).

9. ) The device (1) according to claim 8 characterized in that said elastic elements (20) consist of pieces (21) of yielding material.

10. ) The device (1) according to claim 9 characterized in that said piece (21) of yielding material is made of rubber.

11. ) The device (1) according to claim 8 characterized in that said elastic elements (20) consist of springs.

12. ) The device (1) according to claim 8 characterized in that said elastic elements consist of fluidic elements.

13. ) The device (1) according to any of the preceding claims characterized in that said scraping members (4) are aligned and juxtaposed to each other along a direction generally transversal to the advancement direction (A) of said belt (N) to be scraped.

14. ) The device (1) according to any of the preceding claims characterized in that said frames (3) have one or more through holes (32) adapted to allow passage of material that said scraping members (4) remove from said conveyor belt (N).

15. ) The device (1) according to any of the preceding claims characterized by being provided with a dampening unit (40) interposed between said shaft (15) and the support structure (T) of said device (1), adapted to oppose the free rotation of said shaft (15).

16. ) The device (1) according to claim 1 characterized in that said adjusting means (70) comprise a guide (71) to which a saddle (72) is slidingly coupled, supporting said shaft (15) with said frames (3) and said scraping members (4).

17. ) The device (1) according to claim 8 characterized by comprising further adjusting means (42) interposed between each elastic means (20) and said shaft (15).

18. ) The device (1) according to claim 8 characterized by comprising further adjusting means (52) interposed between each of said frames (3) and said elastic elements (20).

19. ) The device (1) according to claim 8 characterized by comprising further adjusting means (62) interposed between each of said frames (3) and the corresponding scraping members (4).

20. ) The device (1) according to any of claims 17 to 19 characterized in that said further adjusting means (42, 52, 62) consist of grub screws (43) coupled to corresponding threaded holes.
