Description
Technical Field
[0001] This invention relates to the field of agricultural automation equipment technology, and in particular to a grape harvesting and leaf straightening device. Background Technology
[0002] Ningxia, as my country's largest contiguous wine grape producing area and the region with the highest output of winery wines, has seen its wine industry become a source of wealth for its people. To date, it has constructed approximately 195 kilometers of wine grape planting corridors and transformed over 400,000 mu of barren land into "new oases." However, with its long-term rapid development, grapes, as the most widely used fruit in the wine industry, face severe challenges in terms of harvesting timeliness. Currently, most vineyards in my country still rely on manual harvesting. Manual harvesting is not only inefficient and unable to meet the harvesting needs of large-scale vineyards, but it is also prone to damaging leaves and fruits due to improper handling, affecting grape quality.
[0003] Currently, there is no technology that can simultaneously solve the problems of grape harvesting relying on manual labor, low efficiency, and low picking accuracy and easy damage to the fruit caused by leaf obstruction. Summary of the Invention
