A system for reloading a container with proppant. The system includes a transloader having a conveyer belt and a discharge device. The system includes a reloading system comprising a bulk material storage bin having a proppant receiving area, a funnel having an expandable loading tube, and a gate for controlling flow of the proppant from the funnel into the container. The system comprises a reloader comprising a loading bay having a load cell and the container disposed on the load cell.

A bulk cargo blending hopper has a hollow interior volume that is selectively communicated with a source of vacuum pressure. A first conduit has a first end that is connected to the housing of the hopper and communicates with the interior volume of the housing of the hopper. An opposite second end of the first conduit is configured for communication with a source of bulk cargo that is separate from the hopper. A second conduit has a first end that is also connected to a portion of the housing of the hopper and communicates with the interior portion of the housing. A second end of the second conduit is also connected to a portion of the housing of the hopper and communicates with the interior volume of the housing of the hopper.

A mechanical rocker-arm type vertical feeding cushioning device, consisting of two identical cushioning units and a box body (7). The two cushioning units are respectively arranged with a certain height difference on the inner side of the box body (7). Each cushioning unit consists of a cushioning mechanism and a fixing hinge mechanism. The cushioning mechanism is composed of a cushioning plate (1), a spring (5) and a balance weight (6). The fixing hinge mechanism is composed of a hinge plate (2), a right angle circular rod (3) and an elastic limiting device (4). The cushioning plate (1) is fixed to the hinge plate (2) via connection holes and using bolts. The hinge plate (2) is welded to the right angle circular rod (3). The elastic limiting device (4) consists of two elastic limiting plates and a hollow iron ring in a welded manner. The right angle circular rod (3) is connected to the elastic limiting device (4) in a sleeved manner via the hollow iron ring of the elastic limiting device (4). An upper end of the spring (5) is connected to the right angle circular rod (3), and the balance weight (6) is suspended at a lower end of the spring (5). Material is fed to the cushioning plates via a feeding pipe, and falls down after being cushioned twice by the cushioning plates (1). The cushioning device repeatedly cushions and recovers under the joint effect of the cushioning plates (1) and the cushioning balances (6).

An addition system for introducing particulate material into an industrial process is disclosed. The addition system comprises a vessel for holding the particulate material, a weighing device, piping, a controller, and a frame to support the piping. The piping comprises a first valve for transferring the particulate material to the industrial process, and a second valve for transferring a first stream of pressurized gas from a source of pressurized gas to the vessel. The vessel comprises a filling nozzle located on the top of the vessel.

A seed carrier includes a main hopper coupled with a frame via leg members. The main hopper has a discharge. A base plate is coupled with the frame. A support arm is rotatably coupled with the base plate at a first end. A belt driven conveyor having a conveyor hopper at a first end and a discharge at a second end is rotatably coupled with a second end of the support arm at an approximate center of gravity thereof. A latch mechanism is provided for detachably coupling the first end of the conveyor with the first end of the support arm such that the conveyor hopper is position below the main hopper discharge. When the conveyor is uncoupled from the first end of the support arm, the conveyor can rotate to a loading position wherein the discharge thereof can be positioned over the main hopper.

A single robot of a two-lane bin packing system has an end of arm tool (EOAT) that interfaces with two infeed lines and two bins on an ongoing basis so that the robot can pick a group of bags from a first bag group staging area on the first infeed line while a group of bags is being formed in a second bag group staging area by the second infeed line. In addition, by interfacing with two separate bins, one bin can be filled while another, full bin is being replaced with an empty bin. The EOAT thus operates constantly. The bag groups can be formed in layers by discharging bags on a reciprocating shuttle of a pick table assembly.

In order to protect the side walls of a container during loading, in one design, a hopper has one or more barrier wall pairs attached to the hopper walls at the end adjacent to a container. As the hopper is moved forward the barrier walls of the barrier wall pair become closely adjacent to the walls of the container protecting them from damage and helping enable material to be pushed into the container. In a variation, an assembly of barrier wall pairs is set inside a hopper and material is deposited between the barrier walls of the barrier wall pair and then the assembly is moved forward into the container, the material being pushed along with the barrier wall pair into the container. In another variation, the barrier walls may be hinged to the hopper walls. More than one barrier wall pair can be used. Where there are two pairs, the second pair can be hinged to the first so that the second pair can be extended or rotated into a storage position. In a further variation, barrier walls on opposite sides of the hopper are of different length and/or barrier wall pairs are of unequal length.
