The design concept of the highway hedge trimmer is as follows:

1. Function implementation: The machine should have basic cutting, pushing, and retreating functions to ensure safe greening work on highways. To meet this basic requirement, consideration can be given to using two or four drive power systems and scalable pruning devices. At the same time, consideration should be given to setting up a steering mechanism to ensure its flexibility and adapt to different terrain and environmental conditions. In addition, lighting equipment is required for night work. 2. Safety protection: In order to ensure the personal safety of operators, a series of safety protection measures such as full body harnesses, eye shields, etc. need to be configured; At the same time, in order to avoid possible mechanical injury accidents, it is necessary to carry out necessary humanized optimization of the scissors. 3. Environmental adaptability: Considering the special nature of the highway environment (with high dust), it is required that the product has good sealing to prevent pollution and ensure good air flow to improve work efficiency and service life. 4. The combination of design aesthetics and environmentally friendly material selection can enhance the overall appearance and user experience of the product. 5. In terms of energy consumption, the design concept of reducing energy consumption should also be fully considered. 6. The integration of appearance design and human-computer interaction design can make it more convenient for users to operate and control it. The above is the design scheme of the highway hedge machine for your problem! I hope it's helpful to you
