[0002] With the continuous advancement of agricultural modernization, the scale of industrial tomato cultivation has expanded year by year, and the variety of varieties has become increasingly diverse. Currently, industrial tomato cultivation relies primarily on manual labor, especially during the harvest season, which places a high demand on labor. However, rising labor costs and a shortage of human resources are becoming increasingly prominent. Therefore, the development of efficient and automated tomato conveying equipment during the harvest and transportation process is crucial for improving production efficiency and reducing production costs.

[0003] In the industrial tomato harvesting process, conveyors are a key piece of equipment for achieving automation and mechanization.
