Compared with prior art, the beneficial effects of the invention are as follows：Simple in structure, easy to operate, powder conveying continuous uniform,
Rate of powder is controllable, the output of powder end has buffering, i.e.,.
（1）The dust feeder is simple in structure, is divided into five parts：Contain powder powder hopper, driving device, powder feeding wheel and end buffering
Device.It contains powder powder hopper and contains the metal powders of enough dosages in advance, it is adjustable to contain powder powder hopper or more, exports and send by adjusting powder hopper
Distance, which is realized, between powder wheel adjusts powder output flow；Driving device has deceleration part and motor part, high reduction ratio speed reducer
Coordinate servo electrical machinery system that powder feeding wheel is driven to ensure that rate of powder is uniform and stable, while powder feeding speed is adjusted by changing motor speed
Degree；End buffer unit is mounted in powder conveying terminal position, and the powder road of certain angle is equipped in device, and exit connection is sent
Powder mouth.
（2）It is controllable that the dust feeder powder conveys continuous uniform, rate of powder：Motor is taken using private and coordinates high reduction ratio row
It is single by adjusting distance realization between powder hopper outlet and powder feeding wheel simultaneously that star speed reducer controls powder feeding wheel rotational speed regulation powder feed rate
Position time rate of powder adjusting, controls powder output flow, ensures uniform, smooth, the stable supply of powder.
（3）Powder end output buffer：The powder of output flows to end buffer unit by powder feeding pipe, and powder passes through
Laser melting coating molten bath is flowed to by powder-feeding mouth after buffering.
