AI Technical Summary

Technical Problem

Existing tea oil pruning equipment is difficult to adjust in complex forest environments, and the cutting speed cannot be adjusted dynamically, resulting in severe tool wear and unstable pruning effects. It lacks an intelligent control system and is difficult to ensure pruning accuracy.

Method used

A woodland camellia pruning equipment with easy height adjustment was designed. A multi-sensor data fusion system was used to collect branch data in real time through laser ranging, near-infrared sensor and image sensor. Combined with the tool status, a dynamic cutting speed control model was constructed to achieve automatic adjustment of height and cutting speed.

Benefits of technology

It improves the adaptability and precision of pruning equipment, extends the service life of tools, reduces the frequency of manual adjustment, ensures pruning efficiency and stability, and avoids the risk of tool jamming due to branch angles.

Abstract

The invention discloses woodland camellia oleifera pruning equipment with height convenient to adjust, which belongs to the field of agriculture and comprises a holding rod, a bearing rod, a pruning assembly and a pushing assembly. The trimming assembly is composed of a fixed first trimming knife and a sliding second trimming knife, and the pushing assembly drives the second trimming knife to linearly move to complete shearing. The core innovation lies in a cutting speed regulation and control system, cutter states (blade angle and corrosion) and branch parameters (radius, water content and included angle) are obtained through a data acquisition module, a cutter basic coefficient and a pruning condition coefficient are calculated through an evaluation module, a matching degree is generated by combining included angle indexes, and the cutting speed is dynamically adjusted according to the matching degree. The equipment can adapt to different branch conditions, improves the shearing efficiency and precision, prolongs the service life of a cutter, and is particularly suitable for a complex forest land environment. The problems that a traditional tool is inconvenient to adjust and insufficient in intelligence are solved, and reliable technical support is provided for efficient management of camellia oleifera.
