An automatic unloading system for a tank trailer, or other bulk material transfer vehicles has a valve capable of being opened or closed, a solenoid connected to the valve to open or close the valve, a junction box having a connection to the solenoid, and a control box having a connection to the junction box, the control box having a control device that may be operated for controlling operation of the solenoid to open or close the valve with operation of the control device for opening the valve to initiate discharge of granular material stored within the tank trailer. Various electrical lines are provided between these operative components, and further control boxes may be provided along the sides of the vehicle, to furnish and allow further control by the operator, when viewing the unloading process.

A mechanism for precisely controlling a slide gate to provide certain and secure location of a sliding gate in a path of flowable dry bulk material, the mechanism including a rack and pinon gear with a shaft with a diameter hole therethrough for receiving a pin therethrough when the sliding gate is in a desired position. The swing arm is configured to inhibit removal of the pin and thereby prevent unwanted movement of the gate from the desired position. The swing arm is configured for selectively prohibiting accidental and/or intentional but unauthorized removal of the pin depending upon types of objects being placed through the open hole in the swing arm and the first fixed arm open hole.

A self-closing lid that can be applied to a container and which provides a screen to prevent oversized debris from entering an inlet. The self-closing lid preferably includes a pair of flaps that rotate into an open position when material is being applied to the inlet and which rotate closedpreferably via a counterbalance, when material is no longer being applied to the inlet. The autonomous self-closing lid is preferably configured to not open in response to rainwater falling into the inlet and has shapes and/or features which direct the rainwater away from the inlet and outside of the lid.

An automatic bin lid opener system is an apparatus used for opening and closing the top hatch of a storage bin from a control box at ground level to allow the user to avoid climbing ladders to the top of the storage bin. The control box may be operated manually or may be programmed to operate automatically as preferred by the user. The programmable control box may also be operated remotely at great distances via a cell phone using a cell phone application.

A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to a second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.

The present invention discloses a valve opening/closing device for an intermediate bulk container. the container comprises a base, side plates, and a valve provided on the base. Wherein the valve opening/closing device comprises a handle, a motion-transferring device, and a valve opening/closing mechanism, wherein the handle is mounted on the side plate and connected to the motion-transferring device, and the motion-transferring device is used to transfer the force applied on the handle to the valve, so as to open or close the valve. For the valve opening/closing device of the present invention, the operating handle is provided at an appropriate position at the side plate of the container, thereby avoiding bending over or squatting on the ground, etc when opening or closing the valve, facilitating use. In addition, the operating moment can be adjusted through adjusting the transmission ratio of the motion-transferring device, which makes it easy to control the operating force.
