Conveyor systems, adjustment mechanisms, and methods of use

A conveyor system comprising:

• a track defining a track length;
• two or more conveyor segments, wherein each conveyor segment comprises:
• a belt;
• a frame configured to support the belt;
• a hitch configured to operably connect the two or more conveyor segments, wherein the hitch comprises one or more slots, and wherein an adjustment mechanism is disposed through one of the one or more slots;
• an adjustment point,
• wherein each conveyor segment defines a conveyor length;
• and
• the adjustment mechanism corresponds to an elongated, substantially cylindrical piece defining a plurality of surfaces,
• wherein at least one surface of the plurality of surfaces is concentric about a different axis than other surfaces of the plurality of surfaces,
• wherein the at least one surface is configured to operably engage with the adjustment point such that the adjustment mechanism is rotatable in a first direction to increase the conveyor length by one increment and in a second direction to decrease the conveyor length by the one increment.
