| 摘要 |
The invention pertains to a sieve bed for a sifting machine, consisting of rectangular sieve elements (10), which are attached to a support frame (1) with their edges abutting each other, the support frame being provided with mushroom-shaped mounting pins (3), each of which is provided with a head which engages in an interlocking manner in corresponding recesses (11a and 11b) of the sieve elements (10). To facilitate the assembly and disassembly of the sieve elements in a sieve bed of this type and to protect the connection from premature wear the invention proposes that the receptacle (11) for the head (4) of the mounting pin (3) be closed off at the top; that the receptacle (11) for the head (4) of the mounting pin (3) be provided at the bottom with an entrance opening for the head (4) of the mounting pin (3); and that the wall of the receptacle (11) be provided with an inward-projecting bead (12), which can be snapped under the head (4) of the mounting pin (3).
