Mechanical linkage type asphalt mixture batching transmission device
The invention discloses a mechanical linkage type asphalt mixture batching transmission device which comprises a base plate, a feeding driving device, a stone conveyor driving device and an asphalt material conveying device, the feeding driving device, the stone conveyor driving device and the asphalt material conveying device are installed on the base plate, and the feeding driving device is arranged in the middle of the base plate. The hydraulic motor is organically combined with the stone conveyor driving device and the asphalt material conveying device, so that the slurry seal paver feeding hydraulic driving system is simplified, the integration of mechanical, hydraulic and electrical systems is improved, and the production cost is reduced; mechanical linkage type asphalt mixture batching is adopted, so that the asphalt-aggregate ratio of asphalt and stones can be kept constant under the condition that the rotating speed of a transmission shaft fluctuates; in addition, the mode that the high-low-gear gearbox drives the quantitative asphalt pump is adopted, the asphalt pump for conveying micro-flow asphalt is not blocked, and power for conveying large-flow asphalt is abundant; meanwhile, the device adopts the pneumatic clutch to control the start-stop function of the stone conveyor, after the rotating speed of the hydraulic motor is stable, the stone conveyor is started through the pneumatic clutch, the problem that an electro-hydraulic system is slow in response when the hydraulic motor directly drives the stone conveyor is solved, the stone calibration duration does not exceed 20 seconds, calibration errors are reduced, and the calibration accuracy is improved. And the stone conveying precision and the calibration work efficiency are improved. The device is compact in structure, capable of ensuring that the asphalt-aggregate ratio is more accurate and constant, high in practicability and convenient to popularize and use.
本发明公开了一种机械联动式沥青混合料配料传动装置，包括底座板、安装在底座板上的供料驱动装置和石料输送机驱动装置以及沥青材料输送装置，供料驱动装置设置在底座板的中部。本发明通过通过将液压马达与石料输送机驱动装置和沥青材料输送装置有机结合，简化了稀浆封层车供料液压驱动系统，使机械、液压、电气系统集成化提高，降低了生产成本；采用机械联动式沥青混合料配料，使沥青、石料在传动轴转速波动情况下可保证油石比恒定不变；另外，采用高低档变速箱驱动定量沥青泵模式，输送微小流量沥青沥青泵不卡顿、输送大流量沥青动力充沛；同时装置采用气动离合器控制石料输送机的启停功能，在液压马达转速稳定后，通过气动离合器启动石料输送机，避免了液压马达直接驱动石料输送机时电液系统响应慢的难题，石料标定时长不超过20秒，减少了标定误差，提高了石料输送精度和标定工作效率。本装置结构紧凑，可确保油石比更精确和恒定，实用性强，便于推广使用。
