摘要:
A door actuator assembly comprising a base plate mounted to a container. The container includes a distribution orifice and a trap door mounted to the container that moves selectively between a closed position covering the distribution orifice, and an open position not fully covering the distribution orifice. The assembly includes a hook member mounted to the base plate including a hook. The hook engages with the trap door. The trap door moves linearly when the hook member moves. The assembly includes a hook actuator assembly mounted to the base plate, including a hook actuation arm coupled to the hook member. The hook actuation arm extends and retracts, moving the hook member linearly along the base plate when the hook actuation arm extends and retracts, causing the hook member to move the trap door selectively between the closed position and the open position.

The present invention discloses a container, comprising a container body and a lid, the container body comprises a base and side plates, the lid is provided with a first hanging-against structure, the side plate is provided with a second hanging-against structure cooperating with the first hanging-against structure, the first hanging-against structure and the second hanging-against structure are separatable to achieve hanging-against and removal of the lid, the lid is slidable above the container body whereby the first hanging-against structure and the second hanging-against structure are brought close to or away from each other, wherein the first hanging-against structure is slidable along the lid for a certain distance so that the position of the center of gravity of the lid changes relative to the first hanging-against structure. The present invention can realize the multi-directional hanging function of the lid and the container, with novel and reliable structure, simple and convenient operation, solid and durable.

An automated gate actuator system is provided for use in selectively opening and closing a gate that dispenses proppant from a proppant container during the course of a hydraulic fracturing operation. A lever arm is pivotally mounted for movement to place a drive gear in contact with a driven gear to open and close the gate. The gate may be remotely or autonomously actuated in this manner utilizing an electronic control triggered by human and/or sensor input.

A holder with a capacity for two crane buckets holds one of these buckets for filling while the other is being emptied. On return of the emptied bucket to the holder a mechanism is equipped to detach the emptied bucket from the crane cable and to attach the filled bucket to the crane cable. The crane bucket is designed so that its weight operates hydraulic means for causing bottom opening and closing.

An unloader for a shipping container includes a supporter having a frame structure and a pallet base supported by the frame structure and configured to receive the pallet and support the shipping container in an elevated position. A gate moving mechanism is supported by the pallet base and configured to engage the moveable gate assembly when the full shipping container is positioned onto the pallet base. A material director has a first end located beneath the pallet base subjacent of the gate moving mechanism. The material director extends downwardly from the pallet base and terminates at a second end opposite the first end. Bulk material is dispensed from the shipping container into the first end and is discharged from the second end of the material director. Shipping containers may be positioned onto and removed from the pallet base without disassembly of the unloader.
