The invention provides a downhole debris sampler, as a special shaft, an outer cylinder (2) in a cylinder (Fig. 2), the inner cylinder (Fig. 2) and is located in the inner cylinder (Figure 2) and the lower end of the inner cylinder (Fig. 2) in one of the connecting claw extract (Figure 5) the small wedge (34) and small cuboid (35) to extract the sample bag (36), the inner cylinder (Figure 2) carrying the sample bag (36) up to a certain height, the slurry inlet (7), the switch trigger time trigger 555IC (S1 / 4), the cuttings sample bag (36) to collect debris, time trigger 555IC reset, the inner cylinder (Figure 2) continue to rise, on the inner wall of the outer cylinder unloading claw (Figure 6) there are two small wedges on the back (40 and 41) so that the small metal ring sampling bag (5) deformation contraction causes separation of debris from the cuttings into the sampling bag (36) and mud. Downhole automatic sampling.
