A soil sampling device for environmental testing

Abstract

The invention discloses a soil sampling device for environment detection. The soil sampling device comprises a sampling cylinder. The lower surface of the sampling cylinder is provided with a limit groove, and the inner portion of the limit groove is hinged with a connecting block through a hinge shaft. The bottom of the connecting block is fixedly connected with a curved plate, the top of the inner wall of the sampling cylinder is provided with a through hole, a vertical rod is movably connected to the inside of the through hole, a fixed block is fixedly connected to the outer wall of the vertical rod near the bottom end, and the outer wall of the fixed block is fixedly connected with a fixed plate. According to the soil sampling device, a locking block is arranged on the outer wall of the vertical rod, after the curved plate is closed and inserted into the soil to the soil layer of the specified depth, a user can unscrew the locking block and press a handle to open the curved plate under the action of a connecting rod to get soil, the curved plate is closed under the action of the connecting rod, and the problem that the soil detection accuracy is affected due to the fact that soil drops when the sampling cylinder is taken out can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a soil sampling device for environmental detection. Background technique [0002] The earth is one of the eight planets in the solar system. It is the third planet in order of distance from the sun. It is also the terrestrial planet with the largest diameter, mass and density in the solar system. It is 150 million kilometers away from the sun. The earth rotates from west to east and revolves around the sun at the same time. It has a natural satellite: the moon, and the two form a celestial system: the earth-moon system. Originating from the primitive solar nebula 4.6 billion years ago, the earth is an irregular ellipsoid with two poles slightly flattened and the equator slightly bulging. The earth's surface area is 510 million square kilometers, of which 71% is ocean and 29% is land. The earth appears blue from space. There are core, mantle, and shell structures...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a soil sampling device for environmental detection, which solves the problem that most existing soil sampling devices often cannot accurately obtain the soil of the specified soil layer when taking soil, and at the same time, the soil is easy to fall off after taking the soil. Falling confusion affects the accuracy of test results
