Abstract
PURPOSE:To secure the feeding state of a constant quantity for the feeding of a powder material to the side of flame spray gun by means of a quantitative feeding means provided on a feeding hopper by maintaining the powder material in the feeding hopper at a constant level all the time. CONSTITUTION:A means to feed a powder material to a flame spray gun consists of a powder material feeding hopper 3, a replenishing hopper 2 positioned on the upper section of the feeding hopper and a quantitative feeding means 5 provided in the feeding hopper 3. Said hoppers 2 and 3 are communicated with each other through a valve 16, and a level sensing means 24 to sense the quantity of the powder material in the hopper 3 is installed in the feeding hopper 3. A time computing operating means 25 to make the valve 16 opening for a given period of time corresponding to a means 24 is provided in said valve 16 to maintain the powder material in the hopper 3 always at a constant quantity level. As a result, the feeding of powder material to the side of flame spray gun by means of quantitative feeding means can be secured in a state of a constant quantity at all times.
