Work vehicle

Work vehicle and body assembly thereof

A nurse vehicle carries a supply of liquid chemicals or fertilizer for being applied by a sprayer vehicle. A fluid transfer conduit of the nurse vehicle has an end defined by a receptacle that is selectively connected to a complementary dimensioned insert defining an end of a fluid intake conduit of the sprayer vehicle. The receptacle and insert define a coupler assembly that includes an inflatable seal that surrounds the insert and locks the insert and receptacle together when inflated. Flow through the coupler assembly is controlled by first and second poppet valves, which are normally closed preventing flow through valve bodies of the receptacle and insert. Selective inflation of the seal and opening and closing of the poppet valves is automatically controlled in accordance with sequencing logic of an electronic controller so the seal is inflated before the valves are opened and remains inflated until the valves are closed.

An agricultural sprayer includes a centrifugal pump used for transferring fluid from a nurse tank to fill the sprayer tank. It is sometimes required that the centrifugal pump be primed in order to perform the transfer of fluid and this priming is done by creating a vacuum in a priming line that is connected to a suction line extending between an inlet of the pump and to a discharge line of the nurse tank, with the vacuum being caused by routing a flow of compressed air through a venturi having its throat coupled to the priming line.

An engine air intake system includes an engine air intake device and a plenum cooling compartment that is separate from the engine compartment by a baffle. A fan draws outside ambient air into the plenum cooling compartment and out of the plenum cooling area via a heat exchanger. The cooling compartment is designed such that a distance between the heat exchanger and the baffle provides a gap from which the engine air intake device removes ambient air as a source for engine air. An option is provide for the system to withdraw outside ambient air from an area external to the plenum cooling compartment in high debris environments.
