Description

Technical Field

[0001] This invention relates to agricultural harvesting machinery, and more particularly to a main vibrating self-propelled harvester. Background Technology

[0002] In current technologies, the harvesting of dwarf, densely packed dried fruits such as jujubes often involves using vibrating components to strike the branches, causing the fruit to fall and be harvested.
