A method for separating swine waste using at least one perforated conveyor belt and at least one fluid trough. A quantity of swine waste is collected through a slatted floor of a barn into at least one funneling channel. The quantity of swine waste is gravity-fed through the at least one funneling channel onto at least one perforated conveyor belt. Liquid waste is strained from the quantity of swine waste on at least one perforated conveyor belt into the fluid trough, retaining solid waste on the at least one perforated conveyor belt. The solid waste is then transported into a solid-waste storage vessel with the at least one perforated conveyor belt. Simultaneously, the liquid waste is gravity fed into a liquid-waste containment vessel from the at least one fluid trough. The solid waste and the liquid waste are stored to be processed later.

A conveyor system for transporting sand including a transportation element for moving the sand, and a drive subassembly for moving the transportation element on a predetermined path. The drive subassembly includes a sprocket driven by a motor for moving the transportation element along the predetermined path, and a floating idler wheel supportable by the transportation element and positioned on the predetermined path downstream from the sprocket. The floating idler wheel is movable between an upper location and a lower location, depending on the tension to which the transportation element is subjected. The drive subassembly also includes a limit switch activatable upon the floating idler wheel moving to the lower location. Upon activation, the limit switch transmits a signal to a motor switch to de-energize the motor.

Disclosed is a system (100) for a poultry farm. The system (100) includes an automated guided vehicle (110). The automated guided vehicle (110) includes a body (111) adapted to mount a plurality of devices (170), a plurality of wheels (112), a plurality of sensors (113), a collection bin (114) at the rear end (116) of the automated guided vehicle (110), and a detachable protection arrangement (160) at a front (115) of the body (111). The system (100) also includes an overhead power railing unit (120), an open overhead utility line (130) with a vertical water supply line (140) with a pump (142), and a vertical conveyor (150) to retrieve the litter, eggs or wastewater from the collection bin (114) and dispose in the open overhead utility line (130).

The present invention provides a manure handling cart that includes a bin to collect manure and a first conveyor belt to transfer manure into the bin. The cart includes a bin to collect manure and wheels with an electric motor for propulsion. A first conveyor belt mounts to the cart to convey manure into the bin. The bin has a bottom opening and second conveyor belt to discharge manure. The first conveyor belt has four configurations: manure pickup resting on the floor, manure discharge from the second belt, centered storage, and side not in use. The first conveyor belt is mounted to an articulated frame that slides and pivots to adjust the first conveyor belt configuration. A piston pivots the frame at pivot points to configure the first belt. Brackets secure the first conveyor belt in the side storage and centered storage configurations.

A manure conveyor device includes a conveyor including a conveyor belt to receive manure and at least one driver to move the conveyor. One end of the conveyor is fixedly connected to a rotatably drivable drive drum. The manure conveyor device is configured to remove manure located on an upper side of the conveyor belt when the conveyor is wound onto the drive drum.
