Introduction to Split Knife Sampler

It is very common to use the lining soil sample cylinder for sampling in geological surveys. After the soil is delivered to the laboratory, the soil sample for the test is taken again with a ring knife. This method has no problem in the sampling of clay soil, but it is not suitable for sampling in soft soil and sand soil. In addition, when the soil is taken in deep layers, the original stress state of the soil cannot be maintained due to the unloading of the recombination pressure. In particular, it is more difficult for the underwater sands to take the undisturbed soil samples. In order to solve these problems, we developed a split ring knife original sampler. The 37-meter-deep pure sand was taken with good results and the operation was simpler.

The split ring knife sampler consists of three parts: a ring cutter, a ring knife and a sampler boot. The ring knife chamber is a split type, similar to the sampling section of the standard penetrator, with a gap of 5 mm between the ring knife groove and the ring knife groove. If necessary, 4}6 ring cutters can be installed and the outer diameter of the ring knife is 82 mm. The inner diameter is 79.8 mm and the height is 20 mm. The sampler shoe is the same as the general sampler.

Operation steps: Install the ring knife in the groove of the split ring knife chamber, one end of the waste soil section of the sampler and the other end of the sampling shoe. Hammering can be taken when sampling, but it can also press people. After making the hole, remove the waste soil section and the sampler boots at both ends of the ring knife chamber, and gently place the ring knife room on the platform, then use a wire saw to saw the ring knife and the ring knife. Processing, can be sent to the laboratory test.

Wood Hammer Mill

Wood Hammer Mill mainly relies on impact to break the material.It has the characteristics of simple structure, large crushing ratio and high production efficiency, and can be used for dry and wet crushing.The utility model relates to a crusher which can crush the straw of grain, legumes and weed materials.Bearing table and fixed knife table of this machine are on the same plane, shorten the length of the spindle, so the structure is compact, the screen for the ladder, increase the screen packing Angle, the area of powder, so that the crushing effect is good, easy to replace the screen.
