1results about How to "Low technical difficulty" patented technology

This utility model relates to the field of agricultural technology, specifically to a laser weeding machine, including a power supply, a mechanical mounting structure, a system main control unit, functional modules, a motor and its drive module. The functional modules are characterized by comprising a sub-control module, a characteristic spectrum storage chip, a spectrometer, a spectrometer light source, an optical path coupling module, and a laser. This utility model utilizes a right-angle prism to reflect the light emitted from the spectrometer light source and the laser from opposite directions, respectively. A stepper motor can precisely adjust the angle of the right-angle prism, ensuring that the two beams of light from the spectrometer light source and the laser can be focused on almost identical small areas. This improves the accuracy of beam positioning, enhances the reliability and efficiency of the system, and avoids the complex and expensive dichroic mirrors required in traditional laser weeding equipment, thus greatly simplifying the structure of the optical system and reducing production costs and technical implementation difficulties.
