Description

Technical Field

[0001] This utility model belongs to the technical field of cotton laser topping machine, and particularly relates to a wheel shock absorption mechanism for a cotton laser topping machine. Background Technology

[0002] Existing cotton laser topping machines mostly employ a simplified pillar-type shock absorption system to meet the high ground clearance requirements of the machine structure. However, in the "one film, six rows" cotton planting pattern, loose soil and slippery mud after irrigation can cause the laser topping device to wobble and slip during movement, directly affecting the bud detection model. Since cotton buds are approximately 8mm in diameter, the wobble makes it difficult for the detection model to quickly and accurately locate the bud under high ground clearance, impacting the laser topping operation's progress. Furthermore, because the shock absorption mechanism is mounted on the entire guide column, disassembly is inconvenient for maintenance and inspection. Therefore, the existing technology has shortcomings and needs improvement. Summary of the Invention
