Description

Technical Field

[0001] The present invention relates to the technical field of broccoli cutting, and particularly relates to a broccoli cutting device. Background Art

[0002] Broccoli is a kind of vegetable, belonging to the Brassica oleracea var. italica of the Brassicaceae family. Its large flower head, stem and small related leaves can be used as vegetables. As a common vegetable, during its processing, the flower ball needs to be separated from the root and cut into pieces. Traditional processing mostly relies on manual operation, which has problems such as low efficiency, high labor intensity, and uneven cutting sizes. Although existing automated equipment can partially replace manual labor, it still has the following defects: 1. Incomplete cutting: Most equipment cannot efficiently separate the flower ball from the root, resulting in mixed materials during subsequent cutting and affecting the quality of the finished product; 2. Poor adaptability: Fixed cutting parameters are difficult to handle broccoli of different sizes, easily resulting in excessive debris or overly large cut pieces; 3. Messy discharging: The discharging channels for the flower ball and the root are not separated, and secondary sorting is required, increasing the process cost; 4. Low cutting precision: The traditional tool design is single, and the flower ball is easily squeezed and deformed during cutting, damaging the tissue structure.

[0003] In view of the above problems, there is an urgent need for a broccoli cutting device that integrates automatic cutting, precise cutting, intelligent adjustment, and separate-channel discharging. Summary of the Invention
