[0030] Please refer to Figures 1 - 5 , the purposes of recycling and reusing waste rubber are diverse and important. By recycling and reusing waste rubber, the dependence on natural resources (such as petroleum) can be reduced, and the demand for raw materials required for the production of new rubber can be lowered. Through proper recycling and treatment, the pollution risk of waste rubber to soil and water sources can be reduced.

[0031] After waste tires are recycled, initial raw materials can be obtained through processing. Generally, screw conveyor equipment is used for the transportation of these raw materials. When transporting powdered or granular rubber materials, the screw conveyor auger 27 will extrude the powder, and through the operation of the auger, transportation is achieved. However, after transportation, the surface of the auger will be attached with material powder and particles, and long-term accumulation will cause obstruction to the conveyor auger 27. Based on this, the present application provides a rubber powder screw conveyor, which includes a support frame 1 for support and a screw conveyor assembly 2 arranged on the support frame 1;

[0032] An air blowing assembly 3 is installed at the bottom of the screw conveyor assembly 2 for cleaning the transported target object;
