CELL FOR QUEEN Russian patent published in 1994 - IPC

FIELD: bee-keeping. SUBSTANCE: case of the cell has entrance opening, feeding-rack, semicylindrical walls connected by flat-parallel units, bottom provided with 6-8 mm hole where the feeding-rack is mounted. Walls of the case and bottom of the case are perforated. Radius of cross-section of semicylindrical walls is equal to 14-19 mm. Distance between flat-parallel walls relates to maximal distance between semicylindrical walls as 0,29 ≅ l₁/l₂≅ 0,74. Shutter is mounted in entrance opening. Relation of distance l₃ from bottom to shutter to l₁ is equal to 1,6 ≅ l₃/l₁≅ 4,2. Diameter of holes of the shutter is equal to 2.8-3.1. Distance among most remote points of any hole in perforations of case and bottom relates to maximal distance d₂ among closest holes as 1,8≅ d₁/d₂≅ 6,3. EFFECT: reduced traumatism of queen and broodmares. 2 dwg, 1 tbl
