System for spraying the interior of a container

A system for spraying a medium on the interior of a container, the system comprising:

• a non-linear boom having a front end and back end, where the non-liner boom is curved shaped along its length from the front to back end of the non-linear boom and is movable between a retracted and extended position, the non-linear boom further including a drive rack positioned along its length for moving the non-linear boom from a retracted to extended position;
• a plurality of spray nozzles affixed to the front end of the non-linear boom to spray medium directly from the front end of the non-linear boom;
• a support structure moveable between and elevated and non-elevated position for supporting the non-linear boom in both an elevated and non-elevated positioned on a support surface;
• a guide system mounted on the support structure for supporting the non-linear boom substantially over the top of the guide system when the non-linear boom is in a retracted position and where the non-linear boom is curved upward when supported by the guide system, the guide system further including a gear for engaging the drive rack of the non-linear boom;
• and
• a motor positioned on the guide system for driving the gear engaged with the drive rack of the non-linear boom to move the non-linear boom from a retracted to an extended position and allow the front end of the non-linear boom to extend beyond the end of the guide system to enter the container when in an extended position.

A system for washing the interior of a mixing drum having a hopper with a top opening mounted on the mixing drum, the system comprising:

• a non-linear boom having a front end and rear end, where the non-linear boom is curved along its length from the front end to rear end of the non-linear boom in fixed shape, the non-linear boom further including a first and second conduit member;
• at least one spray nozzle positioned on the front end of the non-linear boom in fluid communication with the first conduit member;
• an airline running through the second conduit member for supplying compressed air to the at least one spray nozzle;
• a support structure for supporting the non-linear boom in an elevated and angled position relative to the surface upon which the support structure is fixed in an upwardly curved position;
• and
• a guide system mounted on the elevated support structure, the guide system having rollers mounted thereon for engaging and supporting the non-linear boom in an elevated upwardly curved position, where the guide system supports the non-linear boom at an angle relative to the center axis of the mixing drum when the hopper of the mixing drum is aligned with the front end of the non-linear boom and where the guide system further moveably engages and supports the non-linear boom from a retracted to an extended position to allow the front end of the non-linear boom to enter the mixing drum through the top opening in the hopper on the mixing drum when the front end of non-linear boom is aligned with the top opening of the hopper on the mixing drum, whereby the system is able to spray the interior of the mixing drum without requiring the removal of the hopper on the mixing drum.

A system for spraying the interior of a mixing drum having a hopper with a top opening mounted on the mixing drum, the system comprising:

• a curved boom having a front end and back end where the curved boom has an angle of curvature along its length, where the curved boom further includes at least a first and second conduit member;
• at least one spray nozzle affixed on the front end of the curved boom;
• a connector on the first conduit member for connecting a fluid supply to the first conduit member for supplying medium through the first conduit member to the at least one spray nozzle;
• an airline running through the second conduit member for supplying compressed air to the at least one spray nozzle;
• a support structure;
• and
• a guide system mounted on the support structure in an elevated and angular position, the guide system including at least two rollers for engaging the curved boom and supporting the curved boom in an upwardly curved, elevated and retracted position above the guide system and over the top opening of the hopper on the mixing drum, the guide system further including a drive mechanism for moving the curved boom from a retracted to an extended position along the guide system to allow the front end of the curved boom to enter the mixing drum through the top opening in the hopper on the mixing drum when the front end of the curved boom is aligned with the top opening of the hopper on the mixing drum, and where the support structure maintains the guide system at an angle relative to the surface on which the support structure rests when the drive mechanism is activated to move the curved boom from a retracted to an extended position.
