[0002] Potato, also known as ground egg, potato, etc., is an annual herbaceous plant of the genus Solanum in the Solanaceae family. It is the fourth most important food crop in the world. Potato is native to the Andes Mountains in South America. The tuber is edible and has high economic and nutritional value. The main producing countries are China and the United States. China is the country with the largest total potato production in the world. The existing potatoes need to be turned over and taken out when they are mature. For this purpose, a potato harvester is proposed;
