Specifically, the towable conveyor system comprises a conveyor having a support frame, a plurality of support elements, a drive end with a motor, and an idle end; an elevating carriage having a first end interconnected to the support frame of the conveyor, a second with two or more wheels, and a support member extending upwardly from the elevating carriage; a cable system for raising the conveyor into a position of use and for lowering the conveyor into a towing position; one or more locking mechanisms; and a hitch for connecting the conveyor to a rear end of a towing vehicle.

The proppants processing system comprises one or more in-feed conveyors, one or more out-feed conveyors, one or more primary feed bin assemblies, one or more secondary bin assemblies, the primary and secondary bin assemblies each comprising one or more bins and one or more bin conveyors. The proppants processing system further comprises a final transport conveyor and a control unit adapted to control flow of the proppants. A method of processing proppants, the method comprising the steps of providing proppants comprising dry or wet sand; using an in-feed conveyor, transferring the proppants from a transport vehicle to one or more bins of a primary feed bin assembly; moving the proppants from the one or more bins to a feed bin conveyor; moving the proppants from the feed bin conveyor to a final transport conveyor; and using the final transport conveyor, moving the proppants to a blender.

A conveyor assembly is provided for use with a mobile vehicle. The conveyor assembly includes a conveyor module. The conveyor module includes a first roller assembly. The first roller assembly includes a first rotatable roller body and a second rotatable roller body. The first and second roller bodies are interconnected to each other in such a manner as to share a first rotational axis yet be at least substantially rotationally independent of each other, such that each of the first and second roller bodies can rotate without causing or interfering with rotation of the other of the first and second roller bodies.

An apparatus includes: a housing that encloses a controller configured to control a conveyor system; and an attachment assembly attached to a first side of the housing. The attachment assembly is configured to attach the housing to a side channel of the conveyor system, and the attachment assembly includes an attachment piece, the attachment piece including: a first latch member configured for connection to a first interface on the side channel of the conveyor system; and a second latch member configured for connection to a second interface on the side channel of the conveyor system. When one or more of the first latch member is connected to the first interface and the second latch member is connected to the second interface, the housing is attached to the side channel with a space between the side channel and the first side of the housing.

A padding machine for moving along a side of a ditch, scooping up excavated material from the side of the ditch, and sifting the excavated material into padding material for falling in the ditch comprises a frame comprising side frame members and frame rails spaced apart from the side frame members. A screening belt is driven around pulleys supported by the frame. The screening belt comprises a screen for collecting and conveying the excavated material upwardly. The screen comprises apertures for sifting the excavated material into padding material by permitting the padding material to fall through the apertures of the screen. The screen runs over the frame rails which support the screen. A discharge conveyor is mounted to the frame beneath an upper run of the screening belt. The discharge conveyor receives the padding material passing through the screen and discharges the padding material into the ditch.

Example embodiments may relate to methods and systems for selecting a grasp point on an object. In particular, a robotic manipulator may identify characteristics of a physical object within a physical environment. Based on the identified characteristics, the robotic manipulator may determine potential grasp points on the physical object corresponding to points at which a gripper attached to the robotic manipulator is operable to grip the physical object. Subsequently, the robotic manipulator may determine a motion path for the gripper to follow in order to move the physical object to a drop-off location for the physical object and then select a grasp point, from the potential grasp points, based on the determined motion path. After selecting the grasp point, the robotic manipulator may grip the physical object at the selected grasp point with the gripper and move the physical object through the determined motion path to the drop-off location.

A device conveying a solid material into a radially-arranged stockpile. The device has a 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 trailer 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 trailer chassis. A power unit for generating electrical and hydraulic power is positioned on the trailer chassis. A feed system is mounted to the trailer 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 belt and a belt conveyor are provided for transporting particulate material and especially oilseeds up the belt conveyor. The belt conveyor can include an intake end having a hopper, a discharge end, a body extending between the intake end and the discharge end and a belt. The belt travels along a travel path in the belt conveyor; the belt traveling through the hopper, up an upper run in the body to the discharge end, down a return run in the body, and back through the hopper. The belt can have a top surface having pairs of adjacent ridges provided on the top surface, each ridge having a pair of arms extending from a point, in a travel direction of the belt, wherein each pair of adjacent ridges define a v-channel on the top surface of the belt.

The present invention relates to a stacker for stockpiling bulk material, the stacker comprising: a chassis provided with either wheels or tracks; a conveyor; and a powered, telescoping cylinder leg for moving the conveyor with respect to the chassis, wherein the conveyor is at least 70 ft (21.3 m) long and wherein the telescoping cylinder leg is mounted at one end to the conveyor and at the other end is removably mountable to the chassis from a first, container transport position to a second, road transport position.

A conveyor assembly is provided for use with a mobile vehicle. The conveyor assembly includes a conveyor module. The conveyor module includes a first roller assembly. The first roller assembly includes a first rotatable roller body and a second rotatable roller body. The first and second roller bodies are interconnected to each other in such a manner as to share a first rotational axis yet be at least substantially rotationally independent of each other, such that each of the first and second roller bodies can rotate without causing or interfering with rotation of the other of the first and second roller bodies.
