[0002] The indoor geotechnical test soil sample cutting tool is a tool specially used for cutting soil samples in indoor geotechnical tests. It can easily cut out soil samples of the required shape and size for subsequent geotechnical tests.

[0003] Existing tools for cutting soil samples in indoor geotechnical tests have some obvious shortcomings. Most of them have simple functions. These tools usually use steel wire as cutting elements, which have poor stability during the cutting process and often cut crookedly, affecting the accuracy and repeatability of soil samples. In addition, the cutting process of existing tools is often laborious, requiring operators to have certain strength and skills, which increases the difficulty of operation. At the same time, these tools are prone to generate a lot of dust during the cutting process, which pollutes the test environment and increases the health risks of operators. Therefore, we propose a tool for cutting soil samples in indoor geotechnical tests. Utility Model Content

In addition, the cutting process of the existing tools is often laborious, requiring the operator to have a certain amount of strength and skills, which increases the difficulty of operation. At the same time, these tools are prone to generate a large amount of dust during the cutting process, which pollutes the test environment and increases the health risks of the operator.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The indoor geotechnical test soil sample cutting tool has a design of a horizontal plate, a guide rod, a through hole and a ball. The horizontal plate can move downward along the four guide rods, thereby playing a role of stabilizing and guiding when cutting the soil sample, thereby avoiding skewed cutting and affecting the test effect. The design of the first motor can drive the cutting wire to rotate by controlling the first motor, so that the cutting wire can quickly cut the soil sample, thereby improving the cutting efficiency and shortening the test time. The design of the dust hood, the shell, the second motor, the dust impeller and the filter screen can generate a large amount of dust during the soil sample cutting process.
