CA 2369321
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 bed (12), which can be snapped under the head (4) of the mounting pin (3).
Cette invention concerne un tamis pour cribleuse, comprenant des éléments de tamis rectangulaires (10), lesquels sont fixés bout à bout sur un cadre (1). Le cadre est équipé de goupilles champignons (3) dont la tête vient s'encastrer dans des évidements correspondants (11a et 11b) des éléments de tamis. Afin de faciliter la pose et la dépose des éléments de tamis dans un tamis de ce type et de protéger les zones de liaison contre une usure prématurée, il est proposé dans le cadre de cette invention de fermer à sa partie supérieure le logement (11) de la tête (4) de la goupille de montage (3); de doter ce logement (11) à sa partie inférieure d'un passage pour la tête (4) de la goupille de montage (3); et de monter dans la paroi du logement (11) un tamis (12) orienté vers l'intérieur qui puisse se clipser sous la tête (4) de la goupille de montage (3).
