ZD-QS 30A Inner ring cutter sand extractor

Lifting piston   specification: 30cm 2 X 20mm X 8 only

The inner ring knife sander is used to take loose and weak sand samples that are difficult to prepare, and can take eight 6.18x at a time. 2cm ( 30cm 2) Standard sample, and can be placed directly into the test instrument together with the ring cutter to meet the requirements of conventional bulk test such as bulk density, tree branching, compression and direct shearing. It has the advantages of convenient use, high sampling rate, convenient soil opening and good sampling quality. The original scope of use is limited to sandy soils that are difficult to open. Only the sample is pushed out, and the end face is cut and directly loaded into the consolidation container together with the ring cutter or directly pushed into the straight-cut box to prevent the sample from being loose due to the structure. The weakness caused the opening disturbance. Promote application by the use unit, scope

Expanded to silt soil and even general soil layers, in order to improve the quality of the test and reduce the workload of geotechnical testers. In view of the inadequacies in the original design, the inner ring cutter sander designed and put into production has made the following improvements:

1. The original bushing keyway is matched with a hexagonal piston sleeve rod, and the female sleeve is processed by wire cutting, which is matched with precision and is not easy to wear;

two. The upper piston head assembly, the ring cutter and the split spacer are made of stainless steel, and the corrosion resistance is strong;

three. The sample cover is made of ABS engineering plastic, and is equipped with a leak-proof flat cushion. It does not need to be sealed and the site is more convenient to use.
