Stepless adjusting screw type dust generator

The utility model belongs to the technical field of dust generation, and particularly provides a stepless adjusting screw rod type dust generator. The stepless regulation screw type dust generator mainly comprises a triangular stirring rod, a dust container, a spiral conveying rod and a turning dust conveying device. Wherein the frequency-adjustable micro motor drives the triangular stirring rod in the dust container to enable dust to be evenly discharged to the spiral conveying rod and other structures, the spiral conveying rod conveys the dust to the turning dust conveying device according to different speeds under stepless adjustment of the side motor, and finally the dust is discharged to the environment through the transverse dust conveying device or the longitudinal dust conveying device. According to the device, a certain amount of dust samples can be stored, dust is stirred and discharged through the triangular stirring rod, the discharging process is uniform and not prone to caking and blocking, and
