Specific gravity measuring bench and operation method thereof

Abstract

The invention discloses a specific gravity measuring bench and an operation method thereof. The specific gravity measuring bench comprises an upper bench body and a lower bench body. The upper bench body is provided with a circle of small fixed bottleneck port and three fixing sleeves. A shaking rod is arranged at the opposite side of one of the three fixing sleeves on the upper bench body. The lower bench body is provided with a circle of big fixed bottom port. The lower bench body is also equipped with three fixing solid pipes, the positions of which are corresponding to positions of the three fixing sleeves on the upper bench body. Three supporting legs are arranged below the lower bench body. The specific gravity measuring bench has a simple structure, is easy to operate, is low-cost, and is fast, easy and safe. One-time measurement quantity can be adjusted according to actual situation, and the measurement efficiency is high. Testing speed of the specific gravity measuring bench is 5-10 times faster than testing speed of traditional testing. The specific gravity measuring bench is fast, large in quantity, easy and safe.

Description

technical field [0001] The invention relates to a specific gravity measuring frame and an operating method thereof, in particular to a specific gravity measuring frame for measuring soil physical and chemical properties and an operating method thereof. Background technique [0002] The specific gravity of soil is usually determined by the pycnometer method. This method borrows the principle of drainage weighing method, first measures the water weight of the same volume, and then measures the soil moisture content, then the specific gravity of the soil can be calculated. Soil specific gravity is one of the most important factors affecting soil moisture content. At present, factors such as soil moisture content, soil specific gravity, and soil porosity need to be measured in agriculture, land, and water conservancy projects. Especially, the measurement of soil physical properties in projects such as sand prevention and control, land consolidation, and farmland improvement req...

Problems solved by technology

[0003] At present, the method of measuring specific gravity commonly used at home and abroad is the pycnometer method. Many experts and scholars at home and abroad have carried out a lot of work in the design and manufacture of specific gravity measurement. However, there is no other faster and better method for soil specific gravity measurement. The traditional method The soil specific gravity measurement operation is basically done manually, and the handheld pycnometer is burned on the electric stove for 35 minutes to 1 hour. There are several problems in this operation:

An experimenter can hold up to six pycnometer bottles with both hands at a time, and any more will easily spill liquid or be unsafe

[0005] 2. Too hot and too tired

The experimenter is too close to the electric stove and has to last for 35-60 minutes, so he will be tired and hot

[0006] 3. Not safe

The temperature of the pycnometer held by the experimenter during operation can reach up to 105 degrees. If there are sand particles blocking the pycnometer cap, the bottle will explode, which is very dangerous for the experimenter.

[0007] 4. Slow speed

For a large number of experiments, the traditional measurement speed is too slow. An experimenter can only do 24 soil samples at the fastest speed in a day.
