A hydraulic driving device of a suction car includes a HST circuit, a suction actuator, a supply channel and a switching valve. In the HST circuit, a first connection channel and a second connection channel connect between a traveling drive pump and a traveling motor in a closed circuit. The suction actuator suction drives a suction device by being actuated by a hydraulic pressure. The switching valve allows oil discharged from the traveling drive pump to the first connection channel to be supplied to the traveling motor in a first operation state. The switching valve allows oil discharged from the traveling drive pump to the first connection channel to flow into the supply channel and be supplied to the suction actuator in a second operation state.

The invention provides an unloading system which can be arranged to move a bin or box a distance away from metering equipment of an agricultural machine, such as a dry pneumatic applicator, to allow access to bottom oriented-gates of the bin and retractable chutes for directing particulate material out of the bin and away from the machine. In one aspect, the bin can be lifted or vertically raised by one or more cylinders to allow access to the bottom gates and allow gravity to empty the material from the box, through the bottom gates, down one or more chutes directed to a particular area. One or more hoppers of the bin, typically 1 to 4, can each have a bottom positioned slide gate or door that can be operated to expose a chute for emptying the material out of the box.

An agricultural product delivery applicator for delivering particulate product to a field. The applicator comprises a bin to hold the product, a pneumatic conveying system to provide an airflow, a metering system operably connected between the supply compartment and the pneumatic conveying system, and a rail system. The metering system meters product with the airflow to result in a mixed flow of airflow and product. The rail system includes first and second foldable rails.

A dump-truck fluid assistance system and method for prevention and remediation of material sticking to the truck bed and dampening generation of dust, at different stages of loading, transport, and dumping operations. Fluid is emitted from one or more outflow manifolds inside the bed of the dump truck for one or more purposes of lubricating the truck bed, regulating the temperature of the truck bed, physically flushing material from the truck bed, and dampening generation of airborne particles or dust. Under the control of a controller having a controller transceiver, directed via a cab operator transceiver or remote operator transceiver, a fluid pump sends fluid from a fluid reservoir via a fluid line into the outflow manifolds that emit the flow of fluid variously as spray, stream, jet, drip, or weep, into the bed of the dump truck.

A compressed air cleaning system for removing particles carried and transported in large containers, which includes a container having an upper portion and a lower chute portion for dispensing particles therethrough, a refillable compressed air tank adaptably connecting to an air compressor, and an air hose assembly in communication with the air tank and container.

A trailer includes a metal frame, a first dump bed coupled to the frame substantially near a forward end of the frame, and a second dump bed coupled to the frame substantially near a rearward end of the frame. In an embodiment, the first dump bed is a side-dumping dump bed and the second dump bed is a rear-dumping dump bed.

A lift frame assembly for a vehicle having an air suspension system is described herein which includes a lift frame assembly with a top frame body having a locking mechanism, a lift mechanism with an inflatable air bag operable with respect to the frame body and a source of compressed air in fluid communication with the inflatable air bag; and an air suspension system comprising a height adjustment valve for raising and lowering a frame height in communication with the source of compressed air, wherein the height adjustment valve operates in communication with an air suspension height control valve, and the height adjustment valve is operable to raise and lower the height of the frame by inflating or deflating at least a first pair of air springs positioned on a portion of the lift frame opposite the lift mechanism. The lift frame assembly may be used in conjunction with a cargo container assembly herein having a cargo base frame incorporating securable longitudinally pivotable support legs or lockable extendable and retractable support legs to provide a vehicle cargo container and lift frame assembly.
