摘要： The invention relates to a sieve (1) comprising a first stationary portion, receiving the screens, and a second portion (101) referred to as the cover, translatable (F3) between a first position of closure of the opening of the first portion and a second opening position enabling access to the screens. The invention comprises a first stationary transverse walkway (13) located at the bottom portion of the sieve and suitable for providing access to a first screen when the cover (101) is in the open configuration and to provide access from one side of the sieve to the other only when the cover (101) is in the closed configuration. It comprises at least one second transverse walkway (25) movable between a first position that prohibits access to at least a second screen when the cover (101) is closed and a second position, referred to as the active position, in which the second walkway (25) defines an access path to at least a second screen when the cover (101) is open, the second transverse walkway (25) also defining, in the active position, an access from one side of the sieve to the other, above the first transverse walkway (13).
