High-pressure spraying pile

The high-pressure spraying pile is provided with a stepping motor, the stepping motor is provided with a hollow rotating shaft, the top of the hollow rotating shaft is connected with a bent connector, and the bent connector is connected with a nozzle. The hollow rotating shaft is used as a water flow transmission channel, a structure that the nozzle rotates along with the hollow copper shaft stepping motor is formed, complex gear transmission is omitted, pipeline joints are reduced, the size and the weight of equipment are greatly reduced, the fault rate is also reduced to be very low, the fault is simple, and a user can process the fault by himself/herself. The cost is reduced, after-sale is basically liberated, and considerable cost is saved for enterprises and users. 一种高压喷雾桩，设有步进电机，所述步进电机设有中空转轴，所述中空转轴顶部连接设置弯接头，所述弯接头上连接设置喷嘴。利用中空转轴作为水流传递通道，形成喷嘴随空心铜轴步进电机转动的结构，去掉了复杂的齿轮传动，减少了管路接头，大大减轻了设备的体积和重量，故障率也降到了很低，且故障简单，用户就可自行处理。不但降低了成本，而且基本解放了售后，为企业为用户都节省了可观的费用。
