Oscillator for stirring and vibration of sponge abrasive blast

Abstract

The present disclosure discloses an oscillator for stirring and vibration of sponge abrasive blast, and relates to the technical field of sponge abrasive blasting machines. To overcome the technical deficiencies of a screw rod propulsion structure adopted by an existing sponge abrasive blasting machine, the oscillator comprises a tank, a stirrer disposed in the tank and a power mechanism for driving the stirrer, wherein the stirrer comprises a drive shaft in a flat strip-shaped structure, an upper end of the drive shaft is in transmission connection with the power mechanism, a bottom end of the drive shaft is inserted into a discharge channel of the tank, and each side wall of the drive shaft is connected with more than two flexible stirring arms in spring structures. With the adoption of the drive shaft in the flat strip-shaped structure, a part of an airflow in an airflow pipeline can be intermittently introduced into the tank to blow off a sponge abrasive stuck in corner positions during the rotation of the drive shaft, and meanwhile, under the stirring and vibration of more than two flexible stirring arms in the spring structures connected to each side wall of the drive shaft, the discharging is smooth and thorough.
