The invention discloses a shot blasting machine built-in sand material recovery device which comprises a treatment box body, an absorption cavity formed by combining two isolation plates is formed in the treatment box body, and a conveying belt and a notch allowing a workpiece to pass through are formed in the isolation plates; adsorption assemblies are connected to the two side walls in the treatment box body, and permanent magnets for adsorbing steel sand are connected to the adsorption assemblies. The negative pressure assembly is distributed at the bottom of the adsorption assembly, the negative pressure assembly absorbs sand materials adsorbed on the adsorption assembly through negative pressure, the adsorption assembly is connected with the sweeping assembly, and the sweeping assembly is used for sweeping the adsorbed sand materials which do not fall off. The adsorption assemblies are adsorbed to the two sides of the treatment box body after the shot blasting machine body throws out the sand, the negati
