AI Technical Summary

Technical Problem

The existing automated rubber cutting operation technology is difficult to maximize the cut of yellow skin in areas with thicker bark, resulting in a decrease in rubber production. The "first knife" operation of rubber trees relies on experience operations and lacks automation and intelligence.

Method used

The depth cutting technology based on force-laser detection is adopted to obtain the depth of the rubber tree bark to the xylem through the detection needle and laser rangefinder, fit the rubber cutting depth curve, and realize the spiral cutting trajectory through the rotary switching device and the trajectory drive device to ensure the accuracy and consistency of the rubber cutting depth.

Benefits of technology

It achieves more accurate acquisition of rubber cutting depth, maximizes yellow skin cutting, improves rubber production, and can automatically complete the "first knife" operation of rubber trees to ensure the quality of subsequent rubber cutting.

Abstract

The present invention discloses a rubber tapping end actuator and a rubber tapping method based on force-laser detection of cutting depth. The rubber tapping end actuator comprises a forest walking vehicle, a posture adjustment device, a trajectory guiding device, a rubber tapping actuator, a trajectory driving device and a control module. The present invention uses a force-laser detection method to detect and determine the depth from the epidermis to the wood part, and then subtracts the rubber tapping safety depth to obtain the rubber tapping depth, and fits a rubber tapping depth curve through a series of position measurements. Finally, the rubber tapping knife performs a rubber tapping operation according to the rubber tapping depth curve. This method can obtain the rubber tapping depth more accurately. Compared with the cutting method that relies on profiling technology to control the cutting depth, the present invention can maximize the cutting of the yellow skin and ensure the incision quality, thereby maximizing the rubber production.
