Technical Field
[0001] This utility model relates to the field of tomato harvesting technology, and in particular to an intelligent tomato harvesting device. Background Technology
[0002] Tomato cultivation involves several key steps. First, site selection is crucial. Choose a location with ample sunlight, loose, fertile, and well-drained soil to provide a solid foundation for tomato growth. Before sowing, pre-germinate the seeds to improve germination rate, then carefully cultivate the seedlings in a seedbed. Once the seedlings reach the appropriate height, transplant them to the field with proper spacing between plants and rows. Throughout their growth, ensure a sufficient and balanced water supply, and regularly apply fertilizers rich in nitrogen, phosphorus, and potassium to meet the plant's nutritional needs. Simultaneously, closely monitor for pests and diseases, and promptly control them to prevent their spread. To ensure orderly growth of the tomato plants, provide supports to guide the vines. This not only improves ventilation and light penetration, reducing disease, but also facilitates harvesting when the fruit is ripe. Through these meticulous management steps, a bountiful harvest of brightly colored and delicious tomatoes can be achieved.
[0003] Traditional tomato harvesting robots often use twisting and pulling methods to harvest tomatoes, which often shakes off other tomatoes waiting to be harvested, causing ripe tomatoes to break and affecting the harvest, thus resulting in tomato waste.

[0015] 1. In this utility model, a robotic arm supports a hydraulic rod in front of the tomato to be picked. A 3D depth-sensing camera identifies ripe tomatoes and calculates the distance to the ripe tomato. A controller opens the pneumatic shears, and the hydraulic rod pushes the pneumatic shears to the top of the tomato. The controller then closes the pneumatic shears, causing the tomato to fall into the first collection tube without disturbing other tomatoes.

When insect holes or incomplete rotten parts are detected in the tomato fruits, feedback is sent to the controller in a timely manner. The controller then controls the servo motor to output rotational power, which drives the sleeve to rotate through gears. This causes the second collection tube to be positioned below the pneumatic shears. The pneumatic shears then pick up the rotten tomatoes. This allows for the harvesting of ripe tomatoes as well as rotten tomatoes, thus preventing rotten tomatoes from contaminating other tomatoes.
[0017] 3. In this utility model, the grading rod allows large tomatoes to roll to one side of the partition, while small tomatoes fall directly through the grading rod, thus screening the tomatoes by size. This allows for the sorting of tomatoes while collecting them. Attached Figure Description

During movement, an ultrasonic sensor monitors the road conditions in real time and avoids obstacles. Upon reaching the harvesting area, the drive wheels lift the hydraulic rod to the desired harvesting height. A 3D depth-sensing camera performs image recognition, identifying ripe tomatoes and incomplete or rotten tomatoes. The pneumatic shears are then activated, and the hydraulic rod pushes the shears to the ripe tomato branches. The shears then close to harvest the tomatoes, which fall into the first collection tube and then through the second conveyor tube into the sorting box. Based on the size of the tomatoes, they roll on the grading bar and fall into the corresponding collection holes. When it is necessary to harvest incomplete or rotten tomatoes, the servo motor is activated, which, through gear meshing with the gear ring, rotates the sleeve, positioning the second collection tube below the pneumatic shears. After being harvested by the pneumatic shears, the rotten tomatoes pass through the first conveyor tube into the collection holes at the bottom of the compartment formed by the partition, thus harvesting the rotten tomatoes.
