The present invention relates to a powder medicine injection apparatus having a guide van, which includes: a storage hopper (10) for storing a powder medicine supplied from a supply pipe (11) connected to one side; a guide van (20) including a ceiling portion (21), an outer wall portion (22), and an inner wall portion (23) to guide a dropping of the powder medicine introduced into the storage hopper (10) from the supply pipe (11); a stirring device (30) installed inside the storage hopper (10) to stir the powder medicine; a fixed amount discharging device (50) installed at a lower portion of the storage hopper (10) to discharge the powder medicine by fixed amounts; a primary transfer feeder (60) connected to the fixed amount discharging device (50) to transfer the discharged powder medicine; a dust collector (70) connected to the upper portion of the storage hopper (10) through a pipe and configured to settle dust downward and selectively discharge the settled dust to the outside; a raw material distribution tank (80) in which the dust collected in the dust collector (70) is selectively supplied and stored therein; a secondary transfer feeder (90) installed at a lower portion of the raw material distribution tank (80) to transfer the powder medicine stored in the raw material distribution tank (80); and a mixing tank (100) for mixing the powder medicine with pressure water. Accordingly, the powder medicine is stably discharged by the fixed amounts by minimizing the phenomenon in which the powder medicine is agglomerated by moisture and a cavity is generated.;COPYRIGHT KIPO 2020
