摘要： 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.

摘要： A fluid pump having at least two pump heads in series permits pumping fluid at both high pressure and high volumetric rate. Each pump head has at least two fluid conduits in fluid communication with a housing, the housing containing an impeller for drawing fluid through an inlet in the housing and moving the fluid through the fluid conduits. The at least two fluid conduits of one pump head combine fluid flow at the inlet of a neighboring pump head to provide a single flow of fluid through the inlet into the neighboring pump head. A drive structure passing through the inlets between two pump heads is configured to commonly drive the impellers in the housing of each pump head.

摘要： A liquid medium delivery device has: first and second rigid pipes configured to receive flowing liquid medium from a pump. The first rigid pipe has a first curved portion. The second rigid pipe has a second curved portion. The curved portions are at least partially nested. An actuator is connected to the first rigid pipe or the second rigid pipe or both the first and second rigid pipes. The actuator is operable to move either the first rigid pipe or the second rigid pipe so that either the first curved portion or the second curved portion moves along a common arc of both the first curved portion and the second curved portion. The liquid medium delivery device has an outlet through which liquid medium, for example liquid manure, can be pumped.

摘要： An amphibious vehicle has a floatable vehicle body; ground engaging propulsion structure having a plurality of ground engaging elements powered by a hydraulic motor; a fluid pump for pumping liquid manure; a power source connected to a hydraulic pump and 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.

摘要： An amphibious pumping vehicle comprising: a floatable vehicle body; ground engaging propulsion structure configured to raise and lower relative to the vehicle body; a fluid pump; a first fluid nozzle configured to direct fluid through the air, the fluid nozzle connected by a fluid conduit to the fluid pump; and, a power source configured to provide power to both the ground engaging propulsion structure and the fluid pump. The vehicle is particularly well suited to pumping and recirculating fluid within manure lagoons and is able to be driven up out of the lagoon when the lagoon level has been lowered.
