Automatic unloading system for tank trailer or other bulk materials

An automatic unloading system for a tank trailer or other bulk material conveying vehicle comprising:

• 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;
• a fender mounted control box having a connection to the junction box, the fender mounted control box having a control device that may be operated for controlling operation of the solenoid to open or close the valve with the operation of the control device for opening the valve to initiate discharge of granular material stored within the tank trailer;
• 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.

An automatic unloading system for a tank trailer or other bulk material conveying vehicle having a first unloading assembly, a second unloading assembly, and a third unloading assembly, the automatic unloading system comprising:

• a first valve capable of being opened or closed, the first valve being associated with the first unloading assembly;
• a second valve capable of being opened or closed, the second valve being associated with the second unloading assembly;
• a third valve capable of being opened or closed, the third valve being associated with the third unloading assembly;
• a first solenoid connected to the first valve to open or close the first valve;
• a second solenoid connected to the second valve to open or close the second valve;
• a third solenoid connected to the third valve to open or close the third valve;
• a junction box having a first connection to the first solenoid, a second connection to the second solenoid, and a third connection to the third solenoid;
• a fender mounted control box having a connection to the junction box, the fender mounted control box having a first control device that may be operated for controlling operation of the first solenoid to open or close the first valve with the operation of the first control device for opening the first valve to initiate discharge of granular material stored within the tank trailer, a second control device that may be operated for controlling operation of the second solenoid to open or close the second valve with the operation of the second control device for opening the second valve to initiate discharge of granular material stored within the tank trailer, a third control device that may be operated for controlling operation of the third solenoid to open or close the third valve with the operation of the third control device for opening the third valve to initiate discharge of granular material stored within the tank trailer;
• and
• a control box having a connection to the junction box, the control box having a first control device that may be operated for controlling operation of the first solenoid to open or close the first valve with operation of the first control device for opening the first valve to initiate discharge of granular material stored within the tank trailer, a second control device that may be operated for controlling operation of the second solenoid to open or close the second valve with the operation of the second control device for opening the second valve to initiate discharge of granular material stored within the tank trailer, a third control device that may be operated for controlling operation of the third solenoid to open or close the third valve with the operation of the third control device for opening the third valve to initiate discharge of granular material stored within the tank trailer.
