A conveying system includes a conveyor for moving items along a primary conveyance path. A first buffer table is releasably connected at a first lateral side of the conveyor, and a second buffer table is releasably connected at a second lateral side of the conveyor.

A conveyance apparatus includes a conveyor configured to convey a workpiece, a support unit supporting the conveyor, and a work device which performs a work to the workpiece within a conveying range of the conveyor supported by the support unit.

An interlocking system of tubular members is provided for support of conveyors and mezzanines, each tubular member having cutouts and slots for assembly with other of the tubular members to form elbow joints, tee joints and cross joints, and stiffener brackets to reinforce the interlocking joints to form a strong support structure without the need for welding. A mezzanine conveyor assembly is also provided that includes a support structure constructed of non-welded interlocking tubular members reinforced with stiffener brackets, with a mezzanine/platform and at least one conveyor supported on the support structure.

A proppant conveyor system has: a tower; a bucket elevator; a telescopic conveyor boom mounted to the tower above a ground surface; the telescopic conveyor boom being connected to convey proppant from an outlet of the bucket elevator to a discharge point defined by the telescopic conveyor boom; and the telescopic conveyor boom being mounted to swing in lateral directions relative to an axis of the tower to reposition the discharge point. A method includes: conveying proppant up a bucket elevator, along a telescopic conveyor boom mounted on a tower above a ground surface, and into an inlet of a first storage bin at a well site; repositioning the telescoping conveyor boom over an inlet of a second storage bin at the well site by swinging the telescopic conveyor boom in a lateral direction relative to an axis of the tower; and conveying proppant up the bucket elevator, along the telescopic conveyor boom, and into an inlet of the second storage bin.

An adjustable including a base structure designed for being mounted to an intake of a conveying mechanism for conveying particulates. A bottom portion of a flexible hopper structure is mounted to the base structure. A top structure is mounted to a top portion of the flexible hopper structure. An adjusting mechanism is connected to the base structure and the top structure. The adjusting mechanism enables moving the top structure from a transport position, with the top structure being disposed in proximity to the base structure, to a loading position, with at least a substantial portion of the top structure being disposed at a predetermined distance to the base structure.

An extendable and retractable conveyor includes a hopper for receiving agricultural product, and a housing having an inlet and an outlet that are separated by a fixed distance, the inlet being adjacent to the hopper for receiving the agricultural product from the hopper. The extendable and retractable conveyor also include a belt conveyor disposed within the housing for conveying the agricultural product from the inlet to the outlet, the conveyor defining a direction of conveyance; a hood connected to the outlet for deflecting the agricultural product relative to the direction of conveyance; and a movable spout that is slidably connected to a tube and disposed beneath the hood to receive the agricultural product from the hood, the movable spout being slidable in a direction parallel to the direction of conveyance to thereby extend or retract the conveyor.

This application provides a load-bearing support plate, chain structure, and a conveyor belt structure incorporating them, the load-bearing support plate comprises a first panel, a second panel, and a transition panel for connecting the first panel with the second panel; the first panel is offset in a first direction relative to the second panel, at least one reinforcing rib provided on the first panel, the reinforcing rib extending upwards from the bottom of the first panel to the upper edge of the first panel and forming a bearing surface with the top surface of the first panel. By forming the first panel into a curved shape with the use of reinforcing ribs, the overall support capability is enhanced. Also, by extending the reinforcing ribs to the upper edge of the first panel, the upper edge of the support plate below becomes curved, offering a larger contact area in the thickness direction, thereby improving the stability of the spiral stacking motion. During use, the support plates do not contact the rods, thus not causing wear and enhancing the lifetime or the rods.

A mobile body positioning station and a mobile body positioning system include a first partition, a second partition disposed along a direction intersecting an extending direction of the first partition, and a guide device as a guide disposed on a movement path of a robot as a mobile body. The guide device is disposed along an oblique direction with respect to the direction perpendicular to the extending direction of the first partition to extend from the first partition toward the second partition side. The guide device is configured to make the robot move in the oblique direction more easily than move in directions other than the oblique direction, and the guide device moves the robot along the first partition toward the second partition.

A portable apparatus for transferring bulk material comprises a conveyor which is supported in inclined orientation with its discharge at a higher elevation than its intake. The conveyor is carried on a frame arranged for rolling movement on a support surface, affording the portability of the apparatus. The conveyor is displaceable back and forth relative to the axle assembly in a lateral direction to adjust a position of the discharge of the conveyor in the lateral direction.

A mobile robot is provided for use in an operating environment. The mobile robot may include a mobile robot base, a conveyor system and a drive system. The conveyor system may be supported by the mobile robot base. The conveyor system may include a conveyor belt configured to receive an item with the mobile robot and/or provide the item from the mobile robot. The conveyor system may be configured to support the item during movement of the mobile robot within the operating environment. The drive system may be arranged with the mobile robot base. The drive system may be configured to move the mobile robot within the operating environment and position the conveyor system such that the conveyor belt is operable to receive the item with the mobile robot and/or provide the item from the mobile robot.
