A farm implement is provided. The farm implement includes a frame having a bed and a conveyor mounted to the frame. The farm implement further includes a latch mechanism for securing two or more bulk seed-boxes mounted on a plurality of bulk seed-box locations. The latch mechanism includes a handle to activate the latch mechanism and two or more latches located adjacent to one or more of the bulk seed-box locations, and is moveable between a latched position and an unlatched position. In the latched position, the two or more latches are configured to engage with the bulk seed-boxes to secure the bulk seed-boxes to the bed. In the unlatched position, the two or more latches are configured to disengage from the bulk seed-boxes to allow for the bulk seed-boxes to be unloaded from or loaded onto the bed.

A trailer for particulates, especially for fracturing sand, but also for other materials, has a clam shell gate, which sealingly engages when closed preventing egress of particulates. The gate is attached to a hopper which has an exterior control mechanism thus avoiding wear and tear from particulates. The hopper is an inverted pyramid with downward and inward inclined walls below the trailer. The trailer itself has a cargo compartment with forward and rear sloping walls and upright side walls. The sloping walls of the trailer and the inclined walls of the hopper are inclined at about 38 to the horizontal, which is greater than the angle of repose of fracturing sand to allow complete or near complete discharge of fracturing sand.

A device conveying a solid material into a radially-arranged stockpile. The device has a trailer chassis, with at least one wheeled axle at a first end thereof and, at a second end thereof, means provided for attaching the chassis to a tractor in a mobile condition and for fixed mounting in an operational condition. A stacking conveyor is mounted near the first end of the chassis. A power unit for generating electrical and hydraulic power is positioned on the chassis. A feed system is mounted to the chassis and extends generally along the length thereof from the second end to the first end, to receive the solid material at the second end and transport the solid material to the stacking conveyor.

A tank and a method of carrying a load and discharging a load therefrom. The tank includes a body having a first wall that bounds and defines a first compartment for carrying a load therein and a second wall spaced outwardly from at least a portion of the first wall; wherein a second compartment is defined between the first wall and the second wall. An air piping system is selectively actuated to place the first compartment and the second compartment under substantially similar or substantially equal air pressure. In one example the air piping system pumps air into the first compartment and the second compartment. In another example the air piping system evacuates air from the first and second compartments.

A system and method for enabling a commodity trailer having conventional gravity discharge slide gates to operate with a pneumatic discharge configuration on an as-needed basis is provided. A pneumatic discharge gate, which supports a pneumatic discharge assembly, is configured to directly replace the gravity fed hopper gate and to be retained on the same hopper structure that supported the slide gate so that the slide gate and the pneumatic discharge gate, and the uses thereof, are fully interchangeable.

A trailer assembly has a frame, wheels attached to and bearing the frame and a hopper mounted on the frame. A front conveyor belt is mounted in a front part of the hopper and is operable to rearwardly convey contents of the hopper overlying the belt. A rear conveyor belt is mounted in a rear part of the hopper and is operable in a first mode to rearwardly convey contents of the hopper overlying the rear belt and is operable in a second mode to forwardly convey contents of the hopper overlying the second conveyor belt. Depending on the direction of conveyance of the rear conveyor belt, the two conveyor belts can be operated either to convey contents for dumping through a rear gate or to convey contents for dumping through a bottom gate.
