冷再生机作为旧路面就地再生的关键设备，配置设计围绕破碎拌和、材料输送、动力输出与智能控制四大核心功能，通过各系统协同运作，实现旧沥青路面、水泥稳定层的破碎、添加再生剂、拌和及初步摊铺一体化作业。合理配置可使再生路面强度达新铺路面的 80%-90%，施工效率提升传统工艺的 2-3 倍，配置细节需适配路面硬度、再生深度及材料特性。

　　As a key equipment for on-site regeneration of old road surfaces, the cold recycling machine is designed with four core functions: crushing and mixing, material transportation, power output, and intelligent control. Through the coordinated operation of various systems, it realizes the integrated operation of crushing, adding rejuvenators, mixing, and preliminary paving of old asphalt pavement and cement stabilized layer. Reasonable configuration can make the strength of recycled pavement reach 80% -90% of that of newly paved pavement, and the construction efficiency can be improved by 2-3 times compared to traditional technology. The configuration details need to be adapted to the pavement hardness, recycling depth, and material characteristics.

　　动力系统是核心驱动源，需满足高强度破碎与持续作业需求。主流配置采用大功率柴油发动机，功率范围根据设备型号从 200 马力到 500 马力不等，确保破碎水泥路面时保持稳定输出。发动机匹配冷却系统，在高温环境中能将机体温度控制在 90℃以内，避免过热停机。燃油箱容量根据功率匹配，满足单日施工需求，并配备燃油过滤装置，适应不同地区燃油品质差异。

　　The power system is the core driving source and needs to meet the requirements of high-intensity crushing and continuous operation. The mainstream configuration adopts a high-power diesel engine, with a power range ranging from 200 horsepower to 500 horsepower depending on the equipment model, ensuring stable output when crushing cement pavement. The engine is equipped with an efficient cooling system, which can control the body temperature within 90 ℃ in high temperature environments, avoiding overheating and shutdown. The fuel tank capacity is matched according to power to meet daily construction needs, and equipped with fuel filtration devices to adapt to differences in fuel quality in different regions.

　　破碎拌和装置直接决定再生料级配质量，是配置核心环节。刀鼓直径通常为 600-1000mm，表面布置高强度合金刀头，刀头排列呈螺旋状，确保破碎均匀。刀鼓转速可调节，硬路面采用低转速高扭矩模式，软路面采用高转速模式。拌和深度通过液压系统控制，精度可达 ±1cm，满足不同再生层厚度要求。刀鼓两侧配备侧挡板，防止材料外溢，并通过喷淋装置调节材料含水率。

　　The crushing and mixing device directly determines the grading quality of recycled materials and is the core process of configuration. The diameter of the knife drum is usually 600-1000mm, with high-strength alloy knife heads arranged on the surface in a spiral shape to ensure uniform crushing. The drum speed can be adjusted, with low speed and high torque mode for hard roads and high speed mode for soft roads. The mixing depth is controlled by a hydraulic system, with an accuracy of ± 1cm, meeting the requirements of different regeneration layer thicknesses. Both sides of the knife drum are equipped with side baffles to prevent material overflow, and the moisture content of the material is adjusted through a spray device.

　　输送与布料系统负责再生料转运与初步摊铺。螺旋输送机安装在刀鼓后方，将破碎后的再生料横向输送设备一侧，输送速度与刀鼓转速联动，避免物料堆积。布料刮板可横向伸缩，将再生料均匀摊铺在作业面，刮板高度可调节，控制摊铺厚度。对黏结性强的材料，输送系统需配备防黏附涂层，减少物料黏结。

　　The conveying and fabric system is responsible for the transportation and initial paving of recycled materials. The screw conveyor is installed behind the knife drum to horizontally transport the crushed recycled material to one side of the equipment. The conveying speed is linked to the speed of the knife drum to avoid material accumulation. The fabric scraper can be horizontally extended and retracted to evenly spread recycled materials on the work surface. The scraper height can be adjusted to control the spreading thickness. For materials with strong adhesion, the conveying system needs to be equipped with anti adhesive coatings to reduce material adhesion.

　　液压与控制系统实现精准操作，提升作业稳定性。液压系统采用高压柱塞泵，控制刀鼓升降、输送运转及行走驱动，响应速度快，确保动作协调。操作控制台配备液晶显示屏，实时显示发动机转速、再生深度、摊铺厚度等参数，并具备故障报警功能。部分机型配备自动控制系统，可根据路面硬度自动调节刀鼓转速与行走速度，保持拌和强度一致，降低人工操作难度。

　　The hydraulic and control system achieves precise operation and improves operational stability. The hydraulic system adopts a high-pressure plunger pump to control the lifting, conveying operation, and walking drive of the knife drum, with fast response speed to ensure coordinated action. The operation console is equipped with a LCD display screen, which displays real-time parameters such as engine speed, regeneration depth, and paving thickness, and has a fault alarm function. Some models are equipped with automatic control systems that can automatically adjust the drum speed and walking speed according to the hardness of the road surface, maintaining consistent mixing strength and reducing the difficulty of manual operation.

　　行走系统需适应不同路面条件，保证作业平稳性。履带式行走是主流配置，适应松软基层，避免设备下陷。履带张紧度可调节，减少颠簸，确保刀鼓破碎均匀。轮胎式行走适用于硬化路面，行驶速度快，转场便捷，但在泥泞路面通过性稍逊于履带式。

　　The walking system needs to adapt to different road conditions to ensure smooth operation. Crawler walking is the mainstream configuration, suitable for soft substrates and avoiding equipment sinking. The tension of the track can be adjusted to reduce bumps and ensure even crushing of the drum. Tire type walking is suitable for hardened roads, with fast driving speed and convenient transition, but its passability on muddy roads is slightly inferior to that of track type walking.

　　辅助系统提升设备适应性与性。洒水系统通过喷头向破碎区喷水，调节材料含水率，避免粉尘飞扬。照明系统满足夜间施工需求。装置包括紧急停机按钮、倒车影像及刀鼓防护栏，防止作业中发生事故。

　　The auxiliary system enhances the adaptability and safety of the equipment. The sprinkler system sprays water onto the crushing area through nozzles to adjust the moisture content of the material and prevent dust from flying. The lighting system meets the requirements of nighttime construction. The safety device includes an emergency stop button, a reversing camera, and a knife drum protective barrier to prevent safety accidents during operation.

　　冷再生机配置需根据再生工艺要求组合优化，通过动力、破碎、输送、控制协同设计，实现旧路面材料再生利用，节约资源同时缩短施工周期，成为路面养护工程核心设备。

　　The configuration of the cold recycling machine needs to be optimized according to the requirements of the recycling process. Through the collaborative design of power, crushing, conveying, and control, it can achieve efficient recycling of old pavement materials, save resources, and shorten the construction period, becoming the core equipment of pavement maintenance engineering.
