The ring cutter set solves the problems of large soil disturbance, low test accuracy, and easy deformation of the ring cutter to some extent, but there are still problems of large shear resistance and slow sampling. The utility model's multi-function combination ring knife not only solves the problems of large soil disturbance, low test accuracy, and easy deformation of the ring knife, but also realizes small shear resistance, quick sampling, and provides soil bulk density, subgrade compaction, and the like. A convenient and quick way. The ring cutter set of the utility model comprises a ring knife shell with an inner ring knife composed of two half-pipes with two convex ends at both ends, and one end of the ring knife shell is connected with a hollow cylindrical knife head. One end of the slope is provided with a slope at the inner and outer walls, and the other end is connected to a base provided with a vent hole. The base of the base is connected to a handle, and the handle is provided with a collar, a connecting rod wire and a load hammer. .
The use of a ring cutter to measure compacted soil compactness, in addition to improving efficiency, also greatly reduces the area of ​​disturbed soil. The results of measurement and analysis show that the area required for the new type of circular knife sampler is basically a constant value, with little change with the detection point, while the area required by the traditional circular knife method for measuring compacted soil compactness is within a certain range. Within the larger changes.
[Conical co-rotating twin-screw Cable Material Granulator" has many superiorities ,such as owning high yield (10 to 20 tons/day),ultra-low power consumption (lowest electricity consumption:90kwh for 1 ton of finished product), good mixing and plasticization (high-pressure and plasticization),and can add high proportion of calcium carbonate to the materials (up to 400),and also can be reproduced for 100% reclaimed material with full exhaust and high pressure .It is the best choice for all kinds of cable material granulation, such as PVC,PE,LSNH,and cross-linking,etc.
The Inherent Advantages of Circular Knives in Soil Determination
The application of ring knives in soil bulk density measurement and compaction soil density detection is very common. This is a very classic method. There are certain shortcomings in the method of earth taking with the ring cutter, because of great disturbance in the earth taking process, which destroys the fundamental requirement of collecting the undisturbed soil and makes the test analysis lose its accuracy; the shear resistance is large, sampling is slow, time-consuming and laborious. The efficiency is very low; in the process of earth-fetching, the ring cutter is easily deformed, the soil taking is difficult, and the undisturbed undisturbed soil cannot be collected. The emergence of ring cutters solves this problem.
