The particles with smaller mass and density will be entrained and suspended in the air, diffused outward, and cause pollution to the surrounding air environment. Therefore, a highly efficient treatment and automatic energy-saving and environmentally friendly device for grain unloading by grab at the terminal is proposed. Utility Model Content
