Through an analysis on mud-clogging mechanism of suction nozzles on wet type sweeper, a concept is suggested, that water ratio in dust nearing the wall of suction nozzle duct should be decreased so the mud stickiness can be controlled under a critical value and not sticking to the duct wall whereas water ratio in central dust passage of the duct is properly increased to satisfy effective dust absorbing. On the basis of the concept, a water spraying device is designed with improvement for suction nozzles. In the device, the water hole numbers, diameters and distribution along the nozzle circumference as well as initial direction of water spraying are all determined according to concrete suction nozzle structures.

通过对湿扫型道路清扫车的吸嘴易被泥土堵塞的机理分析，提出降低吸嘴流道近壁的尘土的含水率，控制泥块的黏性处于临界黏性以下，使泥块不黏附于流道壁面；而将吸嘴流道中心部位的尘土的含水率适当加大，以满足有效压尘的解决思路，并根据这种思路改进设计了一种吸嘴喷水装置，按不同吸嘴的具体结构确定孔数、孔径、孔沿圆周的分布规律和喷水的初始方向等要素。
