SCRAPER FOR ANIMAL HUSBANDRY PLANT AND BREEDING PLANT PROVIDED WITH SUCH A SCRAPER

摘要

Scraper (1) comprising a frame (2) for supporting the scraper blades (3A, 3B) and a mechanism (4) for driving the reciprocating movement of said frame (2), each blade (3A, 3B) being mounted on the movable frame (2) pivoting about a pivot axis (XX ') extending orthogonally to the direction of movement back and forth of the frame (2) for the passage of said blade ( 3A; 3B) from an active scraping position in which an edge (9) of the blade attack edge (3A; 3B) is brought closer to the ground in an inactive retracted position, the control mechanism (4) being configured to forming, during each back and forth movement of the frame (2), a drive member for moving the blades (3A; 3B) for the passage of the blades (3A; 3B) from one position to another. The blades (3A; 3B) are alternately in the active position and occupy one, an active position during the forward movement of the frame (2), the other, an active position during the return movement of the frame (2).
