Integrated cement pavement on-site crushing and recycling aggregate method
The invention provides an integrated cement pavement on-site crushing and recycling aggregate method, the direction of the cutting linear speed V1 of a rotor is the same as the direction of the moving speed V2 of a rack, and the method comprises the following steps: a crushing and recycling step when the pavement strength is less than a set value Q1; when the road surface strength is larger than a set value Q1 and the particle size of the crushed stone thrown out of the extruding, striking and crushing space is smaller than a set value R1, crushing and regenerating; and when the road surface strength is greater than a set value Q1 and the particle size of the crushed stone material thrown out of the extruding, striking and crushing space exceeds a set value R1, crushing and regenerating. The gap of the crushing baffle can be adjusted, and the crushing baffle can stretch out and draw back freely, so that one-time crushing and two-time crushing are completed by one mechanical device. Different old concrete materials are effectively crushed by effectively combining the advantages and characteristics of extrusion, jaw crushing and cutting, the crushing baffle capable of freely moving can directly cut and mill when the strength of the concrete is low, and extrusion jaw type and impact type movable crushing is adopted when the strength of the concrete is high. And the difficulty in moving and crushing caused by large strength change of a cement board pavement is solved. According to the invention, on-site rapid and efficient crushing mechanical construction of cement concrete pavements with different strengths can be realized, integrated crushing of recycled aggregates completed by one device is realized, and the requirement of good grading is met.
本发明提出了一种集成式水泥路面就地破碎再生集料方法，转子切削的线速度V1的方向，与机架的移动速度V2的方向相同，包括以下步骤：当路面强度小于设定值Q1时的破碎再生步骤；当路面强度大于设定值Q1且由挤压打击破碎空间抛出的碎石料粒径小于设定值R1时的破碎再生步骤；及当路面强度大于设定值Q1时且由挤压打击破碎空间抛出的碎石料粒径超过设定值R1的破碎再生步骤。对破碎挡板可调整间隙能够自由伸缩，实现了以往一破二破由一台机械设备完成。有效结合挤压、鄂破、切削优势特征对不同旧混凝土材料特点的有效破碎，可自由活动的破碎挡板遇到混凝土强度较低时，可直接切削铣刨，当遇到混凝土强度较高时采用挤压鄂式兼反击式移动破碎，解决了水泥板路面强度变化比较大造成的移动破碎困难。本发明可实现不同强度的水泥混凝土路面就地快速高效破碎机械化施工，实现了一台设备完成的一体化破碎再生集料且满足良好级配的需求。
