Description

Technical Field

[0001] The invention relates to the technical field of soil pollution control, in particular to a soil loosening device for soil pollution control, belonging to the technical field of soil loosening. Background Art

[0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium, and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanide, petroleum, synthetic detergents, 3,4-benzopyrene, and harmful microorganisms brought by urban sewage, sludge, and manure. When there are too many harmful substances in the soil, exceeding the self-purification capacity of the soil, it will cause changes in the composition, structure and function of the soil, and inhibit the activity of microorganisms. When there are too many harmful substances in the soil, exceeding the self-purification capacity of the soil, it will cause changes in the composition, structure and function of the soil, and inhibit the activity of microorganisms. Harmful substances or their decomposition products gradually accumulate in the soil and are indirectly absorbed by the human body through "soil → plant → human body" or "soil → water → human body", reaching a level that endangers human health. This is soil pollution. Soil remediation is a technical measure to restore the normal function of polluted soil. There are many reasons for soil pollution, such as sewage irrigation, deposition of pollutants in the atmosphere, and the large-scale use of mineral fertilizers and pesticides containing heavy metals.

[0003] After searching, in order to solve the problem of soil pollution control, chemical spraying is usually used to purify pollutants in the soil, but many of these soils are agglomerated. If the chemical spraying is directly performed, it is difficult for the chemical agents to penetrate into the soil, and the control effect is not very good. Therefore, the soil is loosened before spraying so that the chemical agents can penetrate deep into the soil. The existing loosening devices are mostly agricultural machinery used for arable land. The depth of entry into the soil is fixed and cannot be adjusted. Therefore, it is impossible to handle soil that is compacted and agglomerated at different depths, resulting in poor control effect. The disclosure number is CN114223325A, which discloses a loosening device for soil pollution control, the loosening device for soil pollution control, the invention discloses a loosening device for soil pollution control, and relates to the technical field of soil pollution control. It includes: a bracket, including: a first support plate; a second support plate located below the first support plate; a plurality of telescopic columns are vertically arranged, evenly arranged between the first support plate and the second support plate, and the two ends of the telescopic columns are respectively fixed to the first support plate and the second support plate; a plurality of loosening devices are respectively arranged between two adjacent telescopic columns; a downward pressing device is arranged on the first support plate, and is used to press down the depth of the loosening device in the soil, including: two third support plates are vertically arranged, symmetrically arranged at the two ends of the second support plate, and the bottom end side wall of the third support plate is fixed to one end of the second support plate; two sets of displacement mechanisms are respectively arranged on the two third support plates. The advantage of the present invention is that a downward pressing mechanism is provided, which can adjust the depth of the loosening device into the soil, treat soil agglomerated at different depths, and achieve better pollution control effects;

[0004] In the field of soil pollution control, traditional soil loosening methods mostly rely on heavy machinery such as excavators or plows for tilling. Although these methods can loosen the soil to a certain extent and promote the diffusion and dilution of pollutants, they have significant disadvantages. First, heavy machinery operations seriously damage the soil structure, which can easily increase the compactness of the soil, affect the subsequent growth of plant roots and soil microbial activities, and thus slow down the self-repair ability of the soil. Secondly, a large amount of dust is easily generated during mechanical operations, which not only pollutes the environment, but also may aggravate the diffusion of pollutants such as heavy metals in the soil, posing a secondary threat to the surrounding ecological environment. In addition, traditional methods are often difficult to reach for deep soil pollution control, and the control effect is limited;

[0005] Therefore, a soil loosening device for soil pollution control is proposed. Summary of the invention
