The invention relates to the technical field of oil exploitation equipment, and discloses a sliding sleeve type multilayer fracturing sand blasting machine. The sliding sleeve type multilayer fracturing sand blasting machine comprises an upper connecting pipe, a lower connecting pipe, a sliding sleeve, a spraying hole and a feeding ball, wherein the sliding sleeve is movably connected with the upper connecting pipe, the sliding sleeve seals the spraying hole, and the sliding sleeve is fixedly connected with the upper connecting pipe through a shear pin. According to the sliding sleeve type multilayer fracturing sand blasting machine, a ball seat is gradually increased along with the fracturing layer, the influence of the diameter of the ball seat on water pressure is reduced, so that the pressure drop of the water pressure is small, and the pressure of the jet flow is ensured to be large enough; furthermore, due to the fact that the water pressure is always kept at a high level, the speed is high, velocity distribution is relatively uniform under high speed, abrasion of the spray head is uniform, and the service life of the spray head is prolonged; and furthermore, due to the factthat the pressure drop of the water pressure is small, the rasied pressure of a ground pump station can also be kept at a lower level, abrasion of the low-level water pressure to an ejector is small,and the service life is further prolonged.
