The expansion of the port area leads to the rapid growth of weeds in less commonly used areas. A weeding machine was designed for port, its structure and principle were introduced, frame stress was analyzed by finite element method, and the effects of weed height and speed on weeding rate were studied. The results showed that the overall frame was relatively safe, but there were some risks in use. When the speed of the weeding machine was 5 km/h and the height weed was 60 cm, the weeding rate was the highest. Finally, the improvement measures were put forward for the shortcomings of weeding machine.
