Technical Field

[0001] The utility model relates to the technical field of tomato picking and collection, in particular to a string-collecting tomato picking device. Background Art

[0002] Greenhouse cultivation of tomatoes and strawberries is now the most common cultivation project in facility agriculture. Traditional tomato harvesting is generally done by manually cutting the bunches and then manually cutting them into granules for sale. In recent years, the popular bunch tomatoes, also known as ear tomatoes, are a new type of tomato variety introduced. The fruits are large and small. Due to their excellent commercial quality, they are very popular among consumers;

[0003] However, the harvesting of this type of tomato is not like that of traditional tomatoes. Since the row spacing is not wide during planting, manual cutting may damage the tomatoes facing away. The existing tomato picking device is not very suitable for this purpose. This is mainly because the picking of bunched tomatoes is different from that of ordinary tomatoes. If a tomato in a bunch is crushed or collided, the appearance and freshness of the entire bunch of tomatoes will be destroyed. Therefore, during the harvesting process, it is necessary to reduce collisions as much as possible when the tomatoes fall into the collection mechanism. Utility Model Content
