Abstract

A device for reducing oocysts of Eimeria spp. uses microwave. In the device, when breeding broiler chickens, litter is recycled for second to fifth breeding after first breeding, and the hardened litter is crushed through a crushing device to form a floor similar to a first breeding environment and simultaneously microwaves of a microwave device are irradiated onto the crushed litter, so that various pathogenic organism such as oocysts of Eimeria spp., viruses, bacteria, parasites, and fungi in the litter are reduced or killed, and thus, pathogenicity and mortality become low, thereby healthily and safely breeding broiler chickens, and accordingly, providing great economic help to poultry farms.

Claims (12)

1 . A device for reducing oocysts of Eimeria spp. using microwave, the device comprising:

a main body unit with a plurality of wheel portions installed at a bottom side thereof to be movable, and a handle portion installed at a top portion thereof to control a direction of movement;

a crushing device installed on a front bottom surface of the main body unit to crush and turn over litter in a chicken coop as it moves;

a microwave device installed on a bottom side surface of the main body unit and irradiating microwave to the litter of the chicken coop that is crushed and turned over by the crushing device to reduce oocysts of Eimeria spp.; and

a control unit installed on a top surface of the main body unit and connected to the microwave device, and controlling the microwave of the microwave device.

2 . The device of claim 1 , wherein the crushing device comprises:

a plurality of connection rods installed on the front bottom surface of the main body unit, and connected to the main body unit with a gear to be rotatable;

a plurality of crushing blades connected to each other by a rotating shaft between the connection rods and directly crushing and turning over the litter of the chicken coop according to the rotation of the rotating shaft; and

a blocking film installed on the plurality of connection rods which are top sides of the plurality of crushing blades to protect the plurality of crushing blades from the outside and simultaneously to prevent the litter crushed by the plurality of crushing blades from scattering upward.

3 . The device of claim 2 , wherein a motor unit connected to the rotation shaft of the plurality of crushing blades to rotate the rotation shaft is further installed on one top side of the main body unit, and operates under the control of the control unit.

4 . The device of claim 3 , wherein a battery unit supplying power to the microwave device, the control unit, and the motor unit is further installed on the other top side of the main body unit.

5 . The device of claim 1 , wherein a plurality of microwave devices is installed on the bottom side surface of the main body unit, connected to the control unit, and controlled by the control unit.
