CA 2278363

A simple, efficient, and rugged dairy parlor entry gate (10) thatis especially useful for identifying animals (30), minimizing the need for lead animals (30) to back up as the gates swing open, and provides for indexing the animals (30) into proper position. The entry gate (10) preferably includes a pair of opposed stanchions (12, 14) defining therebetween a passageway (16), at least one and preferably a pair of gate members (18, 20), and mounting structure for swingably carrying the gate members (18, 20) and mounting them in offset relationship. An antenna (144, 146) may be provided in each of the gate members (18, 20) so that the interrogation field generated thereby swings with the gate member (18, 20). The gate (10) also preferably includes a motive member (24) for swinging the gate members (18, 20) between an open position allowing the passage of animals (30) therebetween and a closed position that both inhibits the passage of animals (30) into the parlor and indexes the last animal (30) into a proper position.

L'invention porte sur le portillon d'entrée simple (10), spécialement pratique pour l'identification des animaux,(30) n'obligeant pas les animaux de tête (30) à reculer lors de l'ouverture du portillon, et indiquant aux animaux (30) la bonne position. Ledit portillon (10) comporte de préférence une paire de poteaux (12, 14) se faisant face et délimitant entre eux un passage (16), au moins une, ou de préférence deux grilles (18, 20), et un bâti où les grilles (18, 20) sont montées pivotantes et décalées. On peut prévoir sur chacune des grilles (18, 20) une antenne (144, 146) dont le champ d'interrogation pivote avec la grille (18, 20). Les grilles (10) comportent également de préférence un élément moteur (24) les faisant passer d'une position d'ouverture laissant passer les animaux (30) à une position de fermeture qui empêche le passage des animaux (30) dans le local de traite et place le dernier animal (30) dans la bonne position.
