<p><P>PROBLEM TO BE SOLVED: To solve a defect of causing risk of impairing supply of a fixed quantity when bulk density of powder changes, when pressure increases, since the weight of the power increases when a large quantity of powder is input in a storage vessel. <P>SOLUTION: This fixed quantity feeder device of the powder includes a carrying system for carrying the powder by the fixed quantity from the storage vessel, sending it to a supply board and dropping-discharging it from a discharge chute, under the storage vessel to which the powder is input. This partition plate is arranged above a supply means for carrying the powder by the fixed quantity, and is arranged for restraining changing of a supply quantity when the bulk density of the powder changes by a residual quantity of a material inside of the storage vessel. The partition plate is provided with a semicircular cutout for avoiding an agitating shaft and a semilunar through-hole for communicating with the cutout. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
