From the perspective of enhancing the utilization of artificial forests in Northeast China, it is necessary to conduct rational harvesting of forest resources. However, the dense undergrowth within the forests severely obstructs the vision of logging workers, negatively impacting harvesting operations. Therefore, a clearing device tailored for artificial forests needs to be designed according to the specific characteristics of artificial forests in Northeast China. Through field investigation, a roller-type clearing device was proposed, and the cutting structure of the device was designed based on relevant data. First, the key components such as the knife roller, knife holder, and cutting tools were designed and analyzed in terms of parameters, and the power requirements of the cutting device were determined. Then, 3D modeling was conducted based on the key design parameters derived from calculations, followed by stress and strain analysis using ANSYS, and dynamic balance simulation analysis using ADAMS software. The results showed that the knife roller design complied with relevant standards and design requirements, and the stress and strain analysis results indicated that the knife holder design met the necessary criteria. Subsequently, a dynamic balance test was performed on the knife roller, with results showing a maximum longitudinal vibration speed of 1.54 mm/s and noise levels below 95 dB. According to ISO standards, this fell into the permissible B-class vibration category. Finally, a prototype was designed and fabricated, and through testing, it was found that the device can successfully complete clearing operations in a cutting area with a shrub density of 11 stems/m², achieving clearing results that meet design requirements.
