technical field

The invention relates to a simple and fast in-situ soil fetching device and a soil fetching method, in particular to a simple and fast in-situ soil fetching device and a soil fetching method for soil detection.

Background technique

Soil is an important basis for high-quality, high-yield, and high-efficiency crops in agricultural production. Obtaining soil samples is a prerequisite for soil laboratory analysis, especially to obtain undisturbed soil, and the collection of undisturbed soil affects soil nutrients and elements. The accuracy and scientificity of the research work on physical and chemical properties such as bulk density and porosity. At present, the acquisition of soil samples is mainly by digging soil samples, but the existing digging soil samplers either use simple traditional tools similar to shovel samples, or use more complicated and difficult to carry electric or original portable improved soil tools. There are many deficiencies in the process of soil sample acquisition. The soil sampling depth of traditional sampling tools is very random, and the amount of soil samples is large, resulting in poor representativeness of soil samples and unbalanced samples; while modern improved soil sampling tools have complex structures, many parts, heavy weight, It is not easy to carry, the efficiency of sampling operation is low, and the price is expensive, which makes the improved earth-borrowing tool not widely used. Therefore, based on the above-mentioned technical problems and defects in the existing sampling technology, it is necessary to improve the equipment and design a simple, fast, accurate and labor-saving soil-taking device for sampling.

The excavation core is a mobile excavation mechanism that can slide up and down along the U-shaped soil-absorbing casing. The excavation core includes a ball handle at the top, a cylindrical excavation rod in the middle, and an excavation opening at the bottom. The excavation rod passes through the perforation in the center of the beam and is set in a U-shaped soil-taking sleeve.

Further, the soil intake at the bottom of the U-shaped soil borrow casing is wedge-shaped, and the soil extraction opening at the bottom of the excavation core is also wedge-shaped. Both the U-shaped soil-taking sleeve and the wedge-shaped end of the unearthed core have slopes, which facilitates soil-taking and saves labor.

Further, a V-shaped excavation protection sheet is provided at the bottom of the excavation core, and the V-shaped excavation protection sheet is reversely connected with the excavation opening. The excavation core is equipped with a V-shaped excavation protection sheet, which can ensure the integrity of the soil sample extracted in the U-shaped soil borrowing casing.

Further, the outer surface of the casing at the lower end of the U-shaped soil-absorbing casing is provided with scales from bottom to top starting from the wedge-shaped exit hole. Since the soil taking device has a scale outside the bottom of the U-shaped soil-taking casing, when the U-shaped soil-taking casing is inserted into the soil to take soil samples, when the height of the U-shaped soil-taking casing is equal to the thickness of the cultivated layer, the On the basis of taking soil samples as the soil of the plow layer, it is convenient to extract soil samples at different depths and analyze samples of different soil layers. The quality of soil samples is not only good in representativeness, but also accurate in different soil layers.

The soil fetching method disclosed by the present invention using the above soil fetching device at the same time:

A simple and rapid in-situ soil retrieval method for soil detection mainly includes the following steps:

(1) Place the U-shaped soil-absorbing casing vertically on the flat sample soil, and lift the excavated core to keep a certain distance from the bottom of the U-shaped soil-absorbing casing;

(2) Insert the U-shaped soil-absorbing casing into the sample soil at the required soil layer depth by pressing on both sides of the cross bar according to the soil-absorbing depth;

(3) Rotate the crossbar to separate the sample soil from the lower and surrounding soil layers, and pull out the U-shaped soil-taking casing through the crossbar;

(4) After the soil is taken out, slowly push out the taken out soil sample through the ball handle on the top of the unearthed core, and mark and seal it for preservation.

Compared with the prior art, the present invention has low production cost and strong practicability, and the sampling method is simple, fast, convenient and effective to take out soil samples, the quality of the soil samples taken is balanced, and the integrity is good, and it is suitable for physical and chemical detection of samples of different soil layers analyze.
