A pump is provided for immersion in a fluid reservoir, such as a pit or lagoon containing liquid manure, from a position at an edge of the reservoir. The pump may be adapted for connection to a farm vehicle, such as a tractor, positioned at the edge of the reservoir. The pump comprises an extensible body, fluid conduit and drive means in order that a length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. In addition, the pump may be pivotable relative to at least a portion of a frame in order that the entrance angle may be adjusted. The pump may comprise a housing with an inlet and an outlet, the outlet in fluid communication with the fluid conduit. An impeller within the housing may direct fluid from the inlet to the outlet in the housing.

An example trailer for a pump can include: a folding system including a first member and a second member that are pivotally connected to one another at a pivot point; a mechanism positioned to move the first member relative to the second member from a transport mode to an operating mode; a ground support system configured to support the trailer relative to a ground; and a guide member configured to hold the pump.

An amphibious vehicle has a floatable vehicle body; ground engaging propulsion structure having a plurality of ground engaging elements; a fluid pump for pumping liquid manure; a power source configured to provide power to both the ground engaging propulsion structure and the fluid pump; and, remote control structure for controlling the ground engaging propulsion structure and a flow of fluid from the fluid pump. The speed and/or direction of the vehicle is remotely controllable by an operator remote from the vehicle when the vehicle is ground engaging and when the vehicle is floating.

The subject invention provides improved methods for processing livestock waste, namely, for solid-liquid separation of manure, utilizing microbe-based products. In preferred embodiments, microorganisms and/or microbial surfactants are utilized to improve solid-liquid separation of livestock manure in ways that enhance the value of manure-based fertilizers to farmers and reduces greenhouse gas and other polluting emissions resulting from manure storage.

A method of agitating liquid manure in a lagoon involves: identifying a boundary perimeter in a lagoon within which an amphibious vehicle must remain while a liquid manure agitation device mounted on the vehicle agitates liquid manure in the lagoon; selecting an agitation pattern to be applied to the lagoon from a group of at least two agitation patterns; and, operating the amphibious vehicle to travel in the lagoon within the boundary perimeter while the liquid manure agitation device agitates the liquid manure in accordance with the selected agitation pattern. The group of at least two agitation patterns includes: a random pattern whereby the vehicle randomly changes direction of travel when the vehicle reaches the boundary perimeter; or, a sweep pattern whereby the vehicle is driven toward a liquid manure pump immersed in the lagoon to push suspended solids in the liquid manure toward the liquid manure pump.

A gearbox particularly useful for liquid manure pumps has a power input shaft that is coupled through a gearset to an impeller of the pump. The rotation axis of the impeller is angled in a range of 55-75° with respect to the rotation axis of the power input shaft. Such an arrangement provides both the necessary power and the correct pump orientation for a trailer-mounted pump to efficiently and effectively pump liquid manure from the bottom of a liquid manure lagoon having long sloped sides.

The pump may comprise a housing with an inlet and an outlet, the outlet in fluid communication with the fluid conduit. An impeller within the housing may direct fluid from the inlet to the outlet in the housing.

A lagoon pump may comprise a chassis structure having front and rear ends; a tow bar couple releasably to the front end of the chassis structure; a centrifugal pump couple to the rear end of the structure; a diesel engine fluidly connected to a fuel tank; a clutch rotationally connected to the diesel engine; an extended driveline directly connected to the clutch at one end and to the pump at an opposed end to drive the pump via rotational energy from the diesel engine; a pair of steerable wheels connected adjacent the front end of the chassis structure; and ground engaging wheels connected under the chassis structure between the ends, wherein the ground engaging wheels are both extendable radially outwardly and rotatable axially relative to the chassis structure. A method of mixing and pumping a slurry material from a lagoon or storage pit utilizing such a pump is also disclosed.

A composting device includes a stirring device, a conveyor belt and a decomposing device. The stirring device, the conveyor belt and the decomposing device are connected successively. A composting method is further provided. An efficient device that can mix livestock and poultry manure, straws and additives fully and uniformly is researched and developed, a conventional method is broken, new innovation is achieved, and the efficiency is improved.

An amphibious pumping vehicle has a floatable vehicle body, a ground engaging propulsion structure, a fluid pump, a plurality of fluid nozzles comprising a first fluid nozzle connected by a fluid conduit to the fluid pump and at least one second fluid nozzle connected to the fluid conduit, a valve structure in the fluid conduit, the plurality of fluid nozzles and the valve structure co-operating to provide directional control and motive power for the vehicle when floating, and a power source configured to provide power to both the ground engaging propulsion structure and the fluid pump.
