冷再生是指利用瀝青再生設(shè)備將舊瀝青路面材料就地打碎，并加入適當?shù)臑r青及改性材料后拌和壓實，以舊路面材料為主修筑道路的技術(shù)。而路面冷再生機是一種出色、環(huán)保的道路施工機械，主要用于舊瀝青路面的再生作業(yè)，其通過對舊瀝青路面銑刨、破碎，然后與水泥、水、乳化瀝青等粘結(jié)劑按一定比例拌和均勻，形成的混合料作為新路面的路基。

Cold recycling refers to the technology of using asphalt recycling equipment to crush old asphalt pavement materials on site, add appropriate asphalt and modified materials, mix and compact them, and use old pavement materials as the main material to build roads. The road surface cold regeneration machine is an efficient and environmentally friendly road construction machinery, mainly used for the regeneration of old asphalt pavement. It milling and crushing the old asphalt pavement, and then mixing it evenly with cement, water, emulsified asphalt and other binders in a certain proportion to form a mixture as the roadbed of the new pavement.

轉(zhuǎn)子是冷再生機的工作部件，用于對路面進行銑刨、拌和，對整機作業(yè)效率和新生混合料的質(zhì)量起著至關(guān)重要的影響。轉(zhuǎn)子切削作業(yè)是在封閉的銑刨室內(nèi)完成的，轉(zhuǎn)子兩端與銑刨室之間容易堆積物料，這使得轉(zhuǎn)子旋轉(zhuǎn)過程中邊刀始終與堆積的物料產(chǎn)生摩擦，造成了邊刀磨損遠快于主銑刀的現(xiàn)象，邊刀磨損到一定程度后，整個轉(zhuǎn)子就無法工作，而此時主銑刀并未損壞，這造成了資源的出色大浪費。

The rotor is the working component of the cold regeneration machine, used for milling and mixing the road surface, which plays a crucial role in the overall efficiency of the machine and the quality of the new mixture. The rotor cutting operation is completed in a closed milling chamber, and materials are easily accumulated between the two ends of the rotor and the milling chamber. This causes friction between the edge cutter and the accumulated materials during the rotation of the rotor, resulting in the phenomenon that the edge cutter wears much faster than the main milling cutter. When the edge cutter wears to a certain extent, the entire rotor cannot work, and at this time, the main milling cutter is not damaged, causing a great waste of resources.

現(xiàn)有的冷再生轉(zhuǎn)子的邊刀是由中間部分刀具按螺旋線規(guī)律延伸而來，沒有考慮到邊刀區(qū)域切削工況與中間部分刀具銑削工況的差異，邊刀區(qū)域的切削工況往往比中間部分刀具惡劣，并且兩側(cè)邊刀直接焊接至轉(zhuǎn)子本體上，當邊刀磨損失效后，整個轉(zhuǎn)子只能整體報廢處理，造成了資源浪費。

The edge cutting of the existing cold regeneration rotor is extended from the middle part of the cutting tool according to the spiral pattern, without considering the difference between the cutting conditions in the edge cutting area and the milling conditions of the middle part of the cutting tool. The cutting conditions in the edge cutting area are often worse than those in the middle part of the cutting tool, and the edge cutting on both sides are directly welded to the rotor body. When the edge cutting tool wears out and fails, the entire rotor can only be scrapped as a whole, resulting in resource waste.

另外，現(xiàn)有的冷再生轉(zhuǎn)子在邊刀區(qū)域布置一把側(cè)面銑削工具，在一定程度上削弱了路槽對邊刀座的磨損，但這對邊刀的保護十分有限，邊刀座磨損依然嚴重。目前現(xiàn)有技術(shù)僅考慮了轉(zhuǎn)子邊刀的切削功能、轉(zhuǎn)子側(cè)面的防護效果，無法解決邊刀磨損過快的問題。

In addition, the existing cold regeneration rotor is equipped with a side milling tool in the edge cutting area, which to some extent weakens the wear of the road groove on the edge cutting seat. However, this protection for the edge cutting is very limited, and the wear of the edge cutting seat is still severe. At present, the existing technology only considers the cutting function of the rotor edge cutter and the protective effect on the rotor side, which cannot solve the problem of rapid wear of the edge cutter.
