Abstract: In an auxiliary tool for feeding including a hook portion and wing portions, the hook portion includes a flat plate-like bottom surface portion, a flat plate-like top surface portion separated from the bottom surface portion in the up-down direction so as to be parallel with the bottom surface portion, a side surface portion coupling the bottom surface portion and the top surface portion on the same side, and claw portions extending downward from an end portion of the top surface portion on the opposite side to the side surface portion, and the wing portions extend in forms of V shapes from the side surface portion in the right-left direction and have elastic force to return to their original shapes when compressed such that angles of the V shapes are decreased.

Abstract: A shutter device, used to open and close an opening provided in a wall with a conveyor belt extending through the opening, includes a pair of posts, an upper shutter and a lower shutter that are movable up and down between the pair of posts, and a lifting-and-lowering mechanism that includes a feed screw having an upper external thread and a lower external thread that are twisted in opposite directions; an upper nut; and a lower nut so as to cause the upper shutter and the lower shutter to move up and down simultaneously.

Abstract: A stirring and transport device for poultry droppings includes a first screw having spiral screw blades, a second screw formed to have a shape symmetric to the first screw, a long groove-like trough having a poultry manure conveyance space, a wet manure charge port through which wet manure collected from a poultry cage is charged into the poultry manure conveyance space, a dry manure charge port through which dry manure is charged into the poultry manure conveyance space, a poultry manure discharge port through which poultry manure obtained by mixing the wet manure and the dry manure is discharged from the poultry manure conveyance space, and a rotating mechanism unit that rotates two screws and conveys the wet manure and the dry manure to the poultry manure discharge port while agitating the wet manure and the dry manure in the poultry manure conveyance space.

Abstract: A roll out and conveyance unit of an egg collector includes endless conveyors which have orbit in the vertical direction on at least portions and are rotationally driven, rotary support portions which support rotation of the endless conveyors, a plurality of egg receiving portions which are attached to the endless conveyors at an equal interval and receive and hold eggs, and a roll out machinery portion which includes an initiation side roll out support portion and a termination side roll out support portion, and discharge plates which are provided so as to project from a termination side rotational shaft of the termination side roll out support portion, make contact with the egg which has been received by the egg receiving portion and has not been rolled out in the vicinity of the termination position to press the egg toward the cumulative egg collection conveyor.

Abstract: The invention relates to an egg collection conveyor and a vertical feeding device for egg collection, and particularly relates to an egg roll out mechanism for an egg collector. The egg collection conveyor collects eggs produced at each cage of a multiple-stage chicken cage and conveys the eggs to horizontally one end side of the conveyor. The vertical feeding device for egg collection is provided on one end side of the multiple-stage chicken cage, conveys the eggs in the vertical direction, and discharges the eggs, collected by the egg collection conveyor, at a previously set position. The vertical feeding device has egg placement means on which eggs are placed and that discharges the eggs at a desired position. The egg placement means has a space section directly under the position where an egg is placed and the space can be in contact with the bottom surface of the egg. The vertical feeding device is connected to an endless conveyor for conveying the collected eggs to a desired position.

Abstract: A cage is provided which is sanitary and efficient and can make hens who tend to gather at the four corners scatter. An oblong and rectangular cage having a floor formed to allow hens and cocks to move freely thereon. The cage includes an outer peripheral section substantially surrounding the entire floor and allowing air to freely pass through it. The cage also includes a plurality of intermediate partitions that are arranged transversally relative to the floor to divide the oblong space on the floor. The intermediate partitions have visually blockading surfaces in order to produce corners that are as relaxing to hens as the four corners.
