Due　to　the　influence　of　population　and　environment,　the　traditional　vegetable　production　methods　in　China　are　undergoing　changes,　and　soilless　cultivation　techniques　are　gradually　receiving　attention.　The　soilless　culture　of　vegetables　is　neatly　arranged　and　suitable　for　automatic　management.　However,　in　actual　production,　the　harvest　of　such　vegetables　is　still　mostly　harvested　and　the　efficiency　is　low.　This　design　is　aimed　at　the　problem　of　high　labor　intensity　and　low　efficiency　of　planting　vegetables,　combined　with　manual　process　analysis　and　harvesting　machinery　research,　and　innovatively　designed　harvesting　institutions　for　planting　vegetables.　In　the　design　process,　solidworks　was　used　to　design　the　scheme.　The　design　scheme　referenced　the　more　mature　research　results,　and　selected　a　reasonable　cutting　method　to　reduce　the　negative　influence　of　vegetable　roots　on　the　cutting　tool　during　cutting;　using　matlab　to　assist　analysis　of　the　linkage　mechanism　kinematic　calculation　ensures　that　the　key　mechanism　has　good　stress　during　the　cutting　process,　improves　the　environment　of　the　mechanism　and　prolongs　its　service　life.　Finally,　completes　the　design　and　analysis　of　the　planting　propulsion　mechanism.　The　development　of　the　facility　vegetable　automatic　harvester　completes　the　automated　production　process　of　vegetables.
