[0002] Soil pollution control devices are mainly used to repair and treat contaminated soil, using various technical means, such as physical separation, chemical conversion or biodegradation, to convert harmful substances in the soil into harmless or low-harm substances; There are multiple processes for soil pollution control. When pollution is detected in the current environment, it is necessary to take relative treatment methods based on the assessment and choose reasonable treatment methods. Most of them will be treated by vehicle-mounted devices. According to the depth of the polluted surface, excavation and soil turning will be carried out in the polluted area. The above treatment will be carried out simultaneously, and then the repaired contaminated soil will be re-paved; Currently, especially in the field of cultivated land, when contaminated planting soil needs to be treated, the contaminated soil in the cultivated land will change the soil structure due to the combination of heavy metal ions with soil particles, or be mixed with decomposed organic matter to form lumps. The mixing of lumps with loose soil will increase the difficulty of treatment, resulting in reduced restoration efficiency and higher costs. In severe cases, the current ground may need to be treated multiple times, and stacking will occur, causing damage to the equipment. Summary of the invention

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Reference Figure 1 to Figure 9A soil pollution control device includes a frame 100, including a liquid storage cavity 101 arranged at the end of the frame 100, a smoothing mechanism 200 perpendicular to the center of gravity of the ground, including an inclined plate 201 rotatably arranged on the surface of the frame 100, and in a working state, is used to smooth the soil sent down, a swing mechanism 300, a swing plate 301 arranged inside the frame 100, and is used to distinguish between soft and hard soil, a processing mechanism 400, which is arranged inside the frame 100 and is used to partition contaminated soil of different hardness, and a connecting mechanism 500, which is arranged on the surface of the frame 100 at the same horizontal plane as the processing mechanism 400, and in a working state, cooperates with the processing mechanism 400 to smooth the soft soil partitions and remove large stones in the hard soil partitions.

[0030] Two groups of first springs 202 are symmetrically distributed on the surface of the inclined plate 201 . The ends of the first springs 202 are fixedly connected to the grafting cylinder 203 . The surface of the grafting cylinder 203 is fixedly connected to the limiting block 204 . The limiting block 204 is fixedly connected to the frame 100 .

[0031] Reference Figure 8 When soil is dropped into the frame 100, when the soil passes through the opening of the frame 100 and enters the curved slope, it will be initially smoothed by the inclined plate 201 of the smoothing mechanism 200. The first spring 202 and the grafting cylinder 203 will provide a certain limiting force for the rotation of the inclined plate 201, causing the inclined plate 201 to tilt, thereby preventing the inclined plate 201 from being damaged by excessive force.

[0032] It should be noted that, when there are too many soil lumps, a conveyor belt needs to be installed on the inner curved slope of the frame 100 to ensure that the contaminated soil can smoothly pass through the smooth height interval formed by the inclined panel 201 and the inner bottom wall of the frame 100.

[0033] A limiting body 302 is provided on the surface of the swing plate 301 , and a connecting rod 303 is rotatably connected inside the limiting body 302 . A second spring is provided inside the connecting rod 303 , and a connecting block 304 is fixedly connected to the end of the second spring. The connecting block 304 is fixedly connected to the frame 100 .

[0034] Reference Figure 4 When the contaminated soil passes through the surface of the swing plate 301 of the swing mechanism 300, the swing plate 301 will be tilted when subjected to excessive force, opening the chamber A below, allowing the soil with more stones and hard soil to be sent down. After the soil is sent down, it will be pulled back and reset by the second spring.

[0035] It should be noted that the elastic modulus of the second spring inside the connecting rod 303 in the reset structure can be adjusted according to the actual soil conditions. The looser the soil and the smaller the density, the smaller the weight of the soil per unit volume. A second spring with a smaller elastic modulus can be used to avoid excessive soil accumulation that cannot drive the swing plate 301 to open. Conversely, the denser the soil and the larger the density, the greater the weight of the soil per unit volume. A second spring with a larger elastic modulus can be used to avoid a small amount of soil accumulation and the swing plate 301 opening, resulting in a decrease in soil treatment efficiency.

[0036] The processing mechanism 400 includes a loading block 401 arranged inside the frame 100, and the interior of the loading block 401 is divided into chamber 1 A and chamber 2 B. A guide block 402 is arranged at the end of the loading block 401, and a flip plate 403 is connected to the side of the loading block 401 close to the guide block 402 through a hinge. A plurality of groups of delivery holes 404 are opened on the surface of the loading block 401 at the feed end of chamber 2 B, and a delivery pipe is arranged inside the delivery hole 404. The end of the delivery pipe in chamber 2 B is fixedly connected to an atomizing nozzle, and the other end of the delivery pipe is fixedly connected to the liquid storage chamber 101.

[0037] The delivery pipe passes through the delivery hole 404 and extends to the interior of the loading block 401, and the contaminated soil is sprayed through the atomizing nozzle.

[0038] When the soil in chamber 1A is being transported, the coupling mechanism 500 cooperates to send the hard stones out from the flip plate 403, while the softer soil blocks cannot push the flip plate 403 away and are squeezed by it to become smaller and continue to be sent downward.

[0039] The connecting mechanism 500 includes a fixed plate body 501 arranged on the surface of the frame body 100, and a driving motor 502 is arranged inside the fixed plate body 501. The output end of the driving motor 502 is fixedly connected to a matching rod body, and the end of the matching rod body is fixedly connected to a first gear 503. The surface of the first gear 503 is respectively meshed with a first gear rod 504 and a second gear rod 506. The end of the first gear rod 504 is fixedly connected to a push block 505, and the surface of the matching rod body is transmission-connected to a crushing piece 507.

[0040] The crushing member 507 includes a transmission member 5071 which is transmission-connected to the mating rod body, the internal transmission of the transmission member 5071 is connected to the first crushing block 5072, the end of the first crushing block 5072 is provided with a second gear 5073, the surface of the second gear 5073 is meshed with a third gear 5074, and the surface of the third gear 5074 is fixedly connected to the second crushing block 5075.

[0041] Reference Figure 5~Figure 7When the device is in use, the driving motor 502 on the connecting mechanism 500 will drive the matching rod body to work, and the matching rod body will drive the first gear 503 and the crushing piece 507 to work. The first gear rod 504 and the second gear rod 506 meshing on the surface of the first gear 503 will drive the contaminated soil in chamber 1A and chamber 2B to be smoothed. At the same time, the first gear rod 504 will drive the push block 505 inside chamber 1A to push out the hard stones, squeeze the soft agglomerated soil, and then fall into the guide block 402. The soft soil in chamber 2B will be smoothed by the second gear rod 506, and at the same time, the disinfectant liquid in the liquid storage cavity 101 will be introduced into the delivery pipe, and then sprayed out by the atomizing nozzle, enter the guide block 402, and then be sent out together with the crushed soil. When the agglomerated soil falls over the first crushing block 5072 and the second crushing block 5075, it will be crushed by them, and then powdered treatment drugs such as lime will be delivered.

[0042] It should be noted that when the pressure of the medicine inside the liquid storage cavity 101 is insufficient, a pressure match can be added, and then the pressurized medicine is sent to the delivery pipe inside the delivery hole 404. The artificial delivery of lime is small doses and is delivered continuously. Disinfectant powder and liquid are selected according to the actual situation based on the nature of the pollutants and soil conditions. Suitable treatment agents, such as chemical stabilizers, microbial preparations, etc., should be selected for different types of soil pollution. For example, for heavy metal pollution, agents that can form stable complexes with heavy metal ions, such as ethylenediaminetetraacetic acid, etc., can be used. For organic pollution, such as petroleum hydrocarbons, pesticides, etc., oxidants or reducing agents can be used for treatment. For acid-base pollution, acid-base neutralizers can be used for treatment.

[0043] The push block 505 and the flip plate body 403 are in the same horizontal plane, and the maximum operating range of the push block 505 does not exceed the maximum opening range of the flip plate body 403 .

[0044] The first crushing block 5072 and the second crushing block 5075 rotate inside the fixed plate 501 .

[0045] It should be noted that the first crushing block 5072 and the second crushing block 5075 drive the third gear 5074 to work through the second gear 5073, and the third gear 5074 drives the second crushing block 5075 so that the first crushing block 5072 and the second crushing block 5075 crush the hard soil.

[0046] A first conveyor belt is disposed inside the swing plate 301 .

[0047] A second conveyor belt is arranged inside chamber 1A and chamber 2B, and a third conveyor belt is arranged on the slope surface of the guide block 402 close to chamber 1A. The guide block 402 is located below the crushing piece 507 and quicklime is loaded inside the chamber.

[0048] The contaminated soil is transported by conveyor belts, which are the power source for transporting the soil. Not only the conveyor belt, but also the pushing or the influence of gravity on the inclined surface can be regarded as the power source. Specific implementation method: When the device is used, first, the frame 100 is fixed to the vehicle-mounted device at the bottom by bolts or welding, and then the vehicle is moved. At the same time, the vehicle-mounted device turns the soil and sends it into the frame 100. The soil blocks fall when they enter the curved surface inside the frame 100. When passing through the space formed by the inclined plate 201 of the smoothing mechanism 200 and the frame 100, the stacked contaminated soil will be smoothed in the first step. When the contaminated soil is sent to the swing plate 301 of the swing mechanism 300, it will be partitioned by the swing plate 301. The contaminated soil with more soil blocks and stones is sent to the interior of chamber 1 A for treatment, and the soft soil will enter the interior of chamber 2 B. After the partitions are sent down, the soil blocks inside chamber 1 A are smoothed for the second time by the first tooth rod 504, and then the soil blocks are broken by the push block 505. The push block 505 sends out the larger and harder stones that the crushing piece 507 below cannot handle in advance through reciprocating lateral movement, and then the workers collect them together. Too many stones in the planting land will have many disadvantages on farming and crop growth, so they need to be collected and processed together, and then fall into the guide block 402. The soft soil in chamber 2B will be smoothed by the second gear rod 506, and at the same time, the disinfectant liquid in the liquid storage cavity 101 is introduced into the delivery pipe, and then sprayed by the atomizing nozzle, enters the guide block 402, and then sent out together with the broken soil blocks. When the agglomerated soil falls over the first crushing block 5072 and the second crushing block 5075, it will be crushed by them, and then powdered treatment drugs such as lime will be added. Then, when the vehicle body moves, the treated soil will be spread on the surface.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
