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.

A liquid pumping vehicle has: a frame; a platform rotatably mounted on the frame; an articulated boom mounted on the platform; a liquid pump mounted on the boom; and, an engine mounted on the platform, so that a rotation axis of the platform is between the boom and the engine and so that a first turning moment created on a first moment arm relative to the rotation axis by weight of the engine and other components on an engine-side of the platform is balanced under operational conditions of the pumping vehicle by a second turning moment created on a second moment arm relative to the rotation axis by weight of the boom and other components on a boom-side of the platform. The vehicle is better balanced for greater stability when in use for pumping a liquid, e.g., liquid manure.

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.

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.

According to an embodiment of the present invention, there is provided a plant cultivation device, including: a body part configured such that a growth space in which a soil and plants are accommodated and to which a nutrient solution is supplied and an auxiliary space which is disposed under the growth space, into which air is introduced and through which a nutrient solution supplied to the soil is discharged are formed therein; a fertilization part disposed inside the body part and configured to supply a nutrient solution to the soil; and a separation part disposed between the growth space and the auxiliary space, configured to prevent the inflow of the soil into the auxiliary space, and provided with a plurality of openings having a smaller diameter; wherein the air introduced into the auxiliary space is introduced into the soil through the openings and promotes the growth of the plants.

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.

Present invention relates to a locking and emptying system of a refill cartridge containing nutrients or chemicals, said system comprising at least one replaceable refill cartridge, at least one receiving socket for the refill cartridge, in every receiving socket a locking mechanism of the refill cartridge, discharge means of the refill cartridge and control means of the locking system and for each refill cartridge a emptying container. The control means of the locking system are set to release the empty refill cartridge from the receiving socket only when the emptying container has enough free volume to receive the content of the next refill cartridge,

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.
