The invention relates to brushing equipment, in particular to mechanical tile surface cement brushing-away equipment for construction. By means of the mechanical tile surface cement brushing-away equipment for construction, oxalic acid left on surfaces of brushed tiles can be washed away conveniently, and water for washing can be drained in time. The mechanical tile surface cement brushing-away equipment for construction comprises a mounting frame, first supporting rods, driven wheels, a conveying belt, a second supporting rod, a rotary shaft, a sector gear, a first belt wheel, a second belt wheel, a flat belt, third supporting rods and the like, wherein the first supporting rods are arranged at the bottom of the interior of the mounting frame in a bilateral symmetry mode. The oxalic acidleft on the surfaces of the tiles is effectively washed away by washing the surfaces of the tiles, thus, workers can directly use the washed tiles, and the working efficiency of the workers is improved.
