摘要: 针对城市落叶处理中设备功能单一、资源化利用率低的问题，本文设计了一款集落叶收集、粉碎、输送、刨坑、下料、整平于一体的多功能一体化落叶处理设备。基于负压吸附原理、机械粉碎原理和机电一体化技术，完成了设备的总体方案设计和关键部件结构设计，利用SolidWorks软件建立了设备三维模型，并通过虚拟装配和运动仿真验证了结构的合理性与运动协调性。对关键受力部件进行了有限元分析，结果表明最大应力小于材料许用应力，变形量满足设计要求。理论计算表明，设备移动速度可达2.5 km/h，粉碎效率85%以上，作业效率60 m²/h，各项性能指标达到预期目标。本设计为落叶资源化利用提供了一种高效、智能的解决方案，具有重要的工程应用价值。

Abstract: Aiming at the problems of single-function and low resource utilization in urban leaf disposal, this paper designs a multi-functional integrated leaf processing equipment integrating leaf collection, crushing, conveying, pit digging, material discharging and leveling. Based on the principles of negative pressure adsorption, mechanical crushing and mechatronics technology, the overall scheme design and key component structure design of the equipment are completed. The three-dimensional model of the equipment is established by SolidWorks software, and the rationality and motion coordination of the structure are verified through virtual assembly and motion simulation. Finite element analysis is carried out on key stress components, and the results show that the maximum stress is less than the allowable stress of the material, and the deformation meets the design requirements. Theoretical calculations show that the moving speed of the equipment can reach 2.5 km/h, the crushing efficiency is more than 85%, and the operating efficiency is 60 m²/h; all performance indicators meet the expected goals. This design provides an efficient and intelligent solution for leaf resource utilization and has important engineering application value.
