CHICKEN KEEPING METHOD AND UNIT FOR ITS IMPLEMENTATION Russian patent published in 2009 - IPC A01K31/00 A01K1/02 

FIELD: agriculture.

SUBSTANCE: method implies protection of chickens against contrary climatic conditions, frost, heat, wind and atmosphere precipitations in the poultry house, airing in the hen yard, feeding, watering, droppings removal, removal of the mature fly larva from the processed dung through the openings in the mesh covers of the subfloor channels placed at the hen yard. Chickens are held in the room where the pig house and the poultry house are combined and made as a square, rectangle, polygon, rhombus, circle or oval. The poultry house is arranged above the pig house; a longitudinal slot is made under the roosts and above the pig feeders for the direct transfer of the chicken droppings to the pig feeders. The subfloor channels of the hen yards are equipped by a gravity dung removal system. The rooms are fitted with double window sashes with the hollows in-between which are equipped by pneumatic loading and unloading devices for loose materials for the purpose of heat insulation of the rooms in winter, in the nighttime, in the daytime in summer. The sash hollows are filled by loose material with the help of a pneumatic loading device. In case of warm sunny weather in winter or day temperature decrease in summer the loose heat insulating material is removed by the pneumatic unloading device and natural lighting is provided. The unit comprises a poultry house and a pig house, a loafing yard, feeders, automatic drinking bowls, ash and sand baths, hen yards with subfloor channels with mesh and bridge covers providing for the possibility for the chickens to remove the mature fly larva from their habitat. The poultry house and the pig house are combined, a longitudinal slot is made in the ceiling between the first and second floors under the roosts and above the pig feeders. Inclined guides allow for the direct transfer of the chicken droppings from the poultry house to the pig feeders. The rooms can be above-the ground, underground or half-underground in the form of a square, rectangle, polygon, rhombus, circle, oval. A gangway to the hen yard from the holes is made as sloped ladder steps for the chicken ups and downs. The subfloor channels of the hen yard are equipped by a gravity pig manure removal system with gates and a quarantine zone. The room is fitted with double window sashes with the hollows in-between. The unit is equipped by pneumatic loading and unloading devices for the light loose material for the purpose of heat insulation in the nighttime, in winter, in the daytime in summer, in case of warm sunny weather in winter or day temperature decrease in summer - for the purpose of removing the light loose material and natural lighting. The loading device comprises a hopper, a feeding screw with a drive. The feeding fan is connected to a cyclone by a pipeline with elongated slots in the lower pipeline base. The cyclone bottom is connected to the counterbalance, is rotatable around its axis and fitted by a microswitch. The unloading device is equipped by a fan, chutes in the sash hollows, pipelines connected with a hopper and branches set at an acute angle to the horizontal chute surface.

EFFECT: design is simplified, functionality is expanded.
