Background
Soil pollutants can be broadly classified into two broad categories, inorganic pollutants and organic pollutants. The inorganic pollutants mainly comprise acid, alkali, heavy metal, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, and the like. The organic pollutants mainly comprise pesticides, phenols, cyanides, petroleum, synthetic detergents, 3, 4-benzopyrene, harmful microorganisms brought by municipal sewage, sludge and animal manure, and the like. When the soil contains excessive harmful substances and exceeds the self-cleaning capacity of the soil, the composition, the structure and the function of the soil are changed, the microbial activity is inhibited, and the harmful substances or decomposition products thereof are gradually accumulated in the soil and are absorbed by the human body through soil-plants-human body or indirectly through soil-water-human body, so that the degree of harming the health of the human body is reached, namely the soil pollution.
Soil remediation is a technical measure to restore normal function to contaminated soil. In the soil remediation industry, the existing soil remediation technologies can be more than one hundred, the common technologies can be more than ten, and the existing soil remediation technologies can be roughly divided into three methods, namely physical methods, chemical methods and biological methods.

Furthermore, a limiting column is annularly installed on the inner wall of the bottom surface of the sample storage cavity, an annular through groove matched with the limiting column is formed in the corresponding position of the top cover, and a limiting groove staggered with the annular through groove is formed in the tail end of the annular through groove.
Furthermore, the drill rod is divided into a first part and a second part, the first part is located in the center of the sample storage cavity, the first part is fixedly connected with a poking plate, and the poking plate can rotate in the sample storage cavity along with the first part of the drill rod.
Further, the second part is located at the center of the drill rod sleeve, a spiral blade is spirally fixed on the second part, and the rotating radius of the spiral blade is equal to the inner diameter of the drill rod sleeve.
Furthermore, the outer wall of the drill rod sleeve is provided with air holes.
Has the advantages that:
the utility model provides a pair of pollute sampling device of soil adopts the mode that rotatory main shaft drove the bull stick, because the drilling rod drives helical blade cutting soil to cut out a groove that can hold the drilling rod cover of chiseling in soil. Because the drilling rod cuts soil, the soil after cutting is lifted and brought into the drilling rod sleeve, and the drilling rod and the helical blade in the drilling rod sleeve continuously rotate to drive the soil to enter the sample storage cavity. Simultaneously, the stirring plate rotates along with the drill rod, and soil at the interface of the drill rod sleeve and the sample storage cavity is continuously scraped into the sample storage cavity. The device can penetrate through the surface soil layer to go deep into the deep soil layer to sample soil, and can perfectly collect and store the sampled soil. Because store up the appearance chamber and form by box body and top cap threaded connection, conveniently take out the soil sample that awaits measuring after the sample. Convenient to collect, store and use, and is convenient to carry due to simple structure and small volume.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.
As shown in the figure, the utility model discloses a pollute sampling device of soil, include: rotatory main shaft 1, store up kind chamber 2, drilling rod 3 and drill rod cover 4, store up 2 bottom fixed mounting rotor rod covers in kind chamber, store up kind chamber 2 with drill rod cover 4 UNICOM, rotatory main shaft 1 passes store up kind chamber 2 center, 1 end of rotatory main shaft with 3 fixed connection of drilling rod, drilling rod 3 runs through drill rod cover 4.
In this embodiment, the sample storage cavity 2 is composed of a top cover 21 and a box body 22 with a through groove formed in the center of the bottom, a spindle fixing head 211 is arranged in the center of the top cover 21, the rotary spindle 1 can be installed in the spindle fixing head 211, and the top cover 21 is in threaded connection with the box body 22.
In this embodiment, the inner wall of the bottom surface of the sample storage cavity 2 is annularly provided with a limiting column 23, the top cover 21 is provided with an annular through groove 212 matched with the limiting column 23 at a corresponding position, and the tail end of the annular through groove 212 is provided with a limiting groove 213 dislocated with the annular through groove 212.
In this embodiment, the drill rod 3 is divided into a first portion 31 and a second portion 32, the first portion 31 is located at the center of the sample storage chamber 2, the first portion 31 is fixedly connected with the stir plate 5, and the stir plate 5 can rotate with the first portion 31 of the drill rod 3 in the sample storage chamber 2.
