Abstract: A gun barrel cleaner rod includes a first cleaner rod and a second cleaner rod. The first cleaner rod and the second cleaner rod are detachably connected. A first lower end of the first cleaner rod and a second upper end of the second cleaner rod are detachably connected through a stud bolt. The stud bolt includes a first threaded end and a second threaded end. The first lower end of the first cleaner rod includes an upper thread, where the upper thread is matched with the first threaded end, and the second upper end of the second cleaner rod includes a lower thread, where the lower thread is matched with the second threaded end. The gun barrel cleaner rod achieves rapid connection through cooperation of stud bolts and a plurality of short rods, which saves storage space, transportation space, and cost.

Abstract: In an aspect, a conveyor system for moving a wheeled structure through a service line is provided. The conveyor system comprises at least one endless belt mounted longitudinally through the service line. The belt has an upper transport portion for moving the vehicle through the service line, and a lower return portion with a support deck below the upper transport portion to support the belt. A debris deflector is mounted between the upper transport portion and the lower return portion to protect the lower return portion from debris falling through the support deck.
