冷再生機(jī)作為舊路面就地再生的關(guān)鍵設(shè)備，配置設(shè)計(jì)圍繞破碎拌和、材料輸送、動(dòng)力輸出與智能控制四大核心功能，通過各系統(tǒng)協(xié)同運(yùn)作，實(shí)現(xiàn)舊瀝青路面、水泥穩(wěn)定層的破碎、添加再生劑、拌和及初步攤鋪相結(jié)合作業(yè)。合理配置可使再生路面強(qiáng)度達(dá)新鋪路面的 80%-90%，施工效率提升至傳統(tǒng)工藝的 2-3 倍，配置細(xì)節(jié)需適配路面硬度、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.

　　動(dòng)力系統(tǒng)是核心驅(qū)動(dòng)源，需滿足高強(qiáng)度破碎與持續(xù)作業(yè)需求。主流配置采用大功率柴油發(fā)動(dòng)機(jī)，功率范圍根據(jù)設(shè)備型號(hào)從 200 馬力到 500 馬力不等，確保破碎水泥路面時(shí)保持穩(wěn)定輸出。發(fā)動(dòng)機(jī)匹配出色冷卻系統(tǒng)，在高溫環(huán)境中能將機(jī)體溫度控制在 90℃以內(nèi)，避免過熱停機(jī)。燃油箱容量根據(jù)功率匹配，滿足單日施工需求，并配備燃油過濾裝置，適應(yīng)不同地區(qū)燃油品質(zhì)差異。

　　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.

　　破碎拌和裝置直接決定再生料級(jí)配質(zhì)量，是配置核心環(huán)節(jié)。刀鼓直徑通常為 600-1000mm，表面布置高強(qiáng)度合金刀頭，刀頭排列呈螺旋狀，確保破碎均勻。刀鼓轉(zhuǎn)速可調(diào)節(jié)，硬路面采用低轉(zhuǎn)速高扭矩模式，軟路面采用高轉(zhuǎn)速模式。拌和深度通過液壓系統(tǒng)控制，精度可達(dá) ±1cm，滿足不同再生層厚度要求。刀鼓兩側(cè)配備側(cè)擋板，防止材料外溢，并通過噴淋裝置調(diào)節(jié)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.

　　輸送與布料系統(tǒng)負(fù)責(zé)再生料轉(zhuǎn)運(yùn)與初步攤鋪。螺旋輸送機(jī)安裝在刀鼓后方，將破碎后的再生料橫向輸送至設(shè)備一側(cè)，輸送速度與刀鼓轉(zhuǎn)速聯(lián)動(dòng)，避免物料堆積。布料刮板可橫向伸縮，將再生料均勻攤鋪在作業(yè)面，刮板高度可調(diào)節(jié)，控制攤鋪厚度。對(duì)黏結(jié)性強(qiáng)的材料，輸送系統(tǒng)需配備防黏附涂層，減少物料黏結(jié)。

　　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.

　　液壓與控制系統(tǒng)實(shí)現(xiàn)合理操作，提升作業(yè)穩(wěn)定性。液壓系統(tǒng)采用高壓柱塞泵，控制刀鼓升降、輸送運(yùn)轉(zhuǎn)及行走驅(qū)動(dòng)，響應(yīng)速度快，確保動(dòng)作協(xié)調(diào)。操作控制臺(tái)配備液晶顯示屏，實(shí)時(shí)顯示發(fā)動(dòng)機(jī)轉(zhuǎn)速、再生深度、攤鋪厚度等參數(shù)，并具備故障報(bào)警功能。部分機(jī)型配備自動(dòng)控制系統(tǒng)，可根據(jù)路面硬度自動(dòng)調(diào)節(jié)刀鼓轉(zhuǎn)速與行走速度，保持拌和強(qiáng)度一致，降低人工操作難度。

　　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.

　　行走系統(tǒng)需適應(yīng)不同路面條件，保證作業(yè)平穩(wěn)性。履帶式行走是主流配置，適應(yīng)松軟基層，避免設(shè)備下陷。履帶張緊度可調(diào)節(jié)，減少顛簸，確保刀鼓破碎均勻。輪胎式行走適用于硬化路面，行駛速度快，轉(zhuǎn)場(chǎng)便捷，但在泥濘路面通過性稍遜于履帶式。

　　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.

　　輔助系統(tǒng)提升設(shè)備適應(yīng)性與安全性。灑水系統(tǒng)通過噴頭向破碎區(qū)噴水，調(diào)節(jié)材料含水率，避免粉塵飛揚(yáng)。照明系統(tǒng)滿足夜間施工需求。安全裝置包括緊急停機(jī)按鈕、倒車影像及刀鼓防護(hù)欄，防止作業(yè)中發(fā)生安全事故。

　　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.

　　冷再生機(jī)配置需根據(jù)再生工藝要求組合優(yōu)化，通過動(dòng)力、破碎、輸送、控制協(xié)同設(shè)計(jì)，實(shí)現(xiàn)舊路面材料出色再生利用，節(jié)約資源同時(shí)縮短施工周期，成為路面養(yǎng)護(hù)工程核心設(shè)備。

　　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.
