Shaker crank for a harvester

A rotatable crankshaft affixed transversely beneath a plurality of endless loop spaced-apart parallel conveyor belts on a tomato harvester;

• means affixed to said crankshaft for applying rotary power to axially rotate said crankshaft;
• said crankshaft including a plurality of offset placed crank journals equal in number to the conveyor belts, with a crank journal located under each of the conveyor belts;
• a plurality of elongated tubular bearing sleeves, one of the bearing sleeves affixed over each of the crank journals,
• the bearing sleeve covered crank journals positioned relative to the conveyor belts so that with rotation of said crankshaft the sleeves are raised individually to impact the respective conveyor belts and impart temporary upward movement in the conveyor belts and thus vibration capable of dislodging tomatoes from vines when riding atop of the conveyor belts,
• the bearing sleeves covering each crank journal sized with an internal diameter substantially larger than an external diameter of the crank journal to allow both eccentric movement and rotation of the sleeves about the journals,
• each of the bearing sleeves split lengthwise into two sections connected together by interlocking tongue and groove snap lock means on opposing edges for affixing the two sections of the sleeves together about the crank journals,
• journal end plates affixed on said crankshaft at two oppositely disposed ends of each crank journal adjacent terminal ends of each sleeve for laterally retaining the sleeves positioned over the crank journals;
• each of the bearing sleeves being slightly shorter in length relative to the journal length and spacing between journal end plates so that each bearing sleeve is free to rotate about the journal.
