The invention discloses dust removal equipment for grain particles. A material storage bin is arranged inside a main machine shell, a feeding opening communicated with the material storage bin insidethe main machine shell is formed in the middle of a material sweeping platform at the top of the main machine shell, a material receiving groove is annularly formed around the material sweeping platform, a spiral feeding mechanism is located at the feeding opening and used for feeding materials upwards from the material storage bin, a material sweeping mechanism is located on the upper surface ofthe spiral feeding mechanism and connected with the spiral feeding mechanism, a material sweeping brush is arranged at the bottom of the material sweeping mechanism, the lower end of the material sweeping brush abuts against the material sweeping platform, and an air guiding cover is located above the material sweeping platform. According to the optimally-designed dust removal equipment for the grain particles, the grain particles in the material storage bin are fed to the material sweeping platform through the spiral feeding mechanism, the particles on the material sweeping platform are spread through the material sweeping brush and then fall into the material receiving groove in the periphery, the air guiding cover performs dust removal on the particles on the material sweeping platform,and it is guaranteed that the dust of the grain particles is thoroughly removed.
