Description

Technical Field

[0001] This utility model belongs to the field of soil remediation technology, specifically relating to an integrated tillage-chemical slow-release device for remediation of heavy metal contaminated soil. Background Technology

[0002] With the acceleration of industrialization and the continuous expansion of urbanization, the problem of heavy metal pollution in soil has become increasingly serious, posing a significant threat to the ecological environment and human health. Heavy metals such as lead, mercury, cadmium, and chromium are difficult to degrade naturally once they enter the soil, accumulating continuously. These heavy metals not only reduce soil fertility, affecting crop growth and yield, but also enter the human body through the food chain, causing various diseases. For example, lead poisoning can damage the nervous and hematopoietic systems, while mercury poisoning can affect brain and kidney function.

[0003] Currently, there are numerous remediation technologies for heavy metal contaminated soil, mainly including physical remediation, chemical remediation, and bioremediation. However, these remediation technologies have many problems in practical applications. For example, the soil replacement method in physical remediation, although it can effectively reduce the content of heavy metals in contaminated soil, requires a large amount of soil resources, is costly, and can easily damage the surrounding ecological environment; the leaching method in chemical remediation, although it can quickly remove heavy metals from the soil, leads to soil nutrient loss and damage to soil structure, and improper treatment of the leaching solution may also cause secondary pollution; bioremediation, although environmentally friendly, has a long remediation cycle, is greatly affected by soil environmental conditions (such as temperature, pH, and microbial community), and the remediation effect is unstable.

[0004] Furthermore, most existing soil remediation equipment has only one function and cannot meet the synergistic requirements for tillage and chemical application in the remediation of heavy metal contaminated soil. Even if some equipment has tillage and chemical application functions, the tillage width and chemical spraying range are often fixed, making it difficult to adapt to soil remediation scenarios with different areas and levels of contamination. Utility Model Content

[0005] The purpose of this invention is to provide an integrated tillage-chemical slow-release device for the remediation of heavy metal contaminated soil. The device can adjust the working width of the tillage equipment and the chemical slow-release equipment according to the user's needs, thereby adapting to different heavy metal contaminated soils.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An integrated tillage-chemical slow-release device for remediation of heavy metal contaminated soil includes a tillage device and a chemical slow-release device. The tillage device includes a crossbeam, and multiple tillage shovels are mounted on the lower side of the crossbeam. One of the tillage shovels is a fixed shovel body that is fixedly connected to the lower side of the crossbeam, and the other tillage shovels are movable shovel bodies that can move on the lower side of the crossbeam.

[0008] The crossbeam is also equipped with an adjustment mechanism that is connected to multiple movable shovel bodies via a transmission.

[0009] The pesticide slow-release device includes multiple pesticide slow-releasers, which are respectively fixedly connected to the rear side of multiple tillage shovels.

[0010] Furthermore, the adjustment mechanism includes multiple mounting sleeves, one of which is fixedly connected to the outside of the crossbeam, the fixed shovel body is fixedly connected to the lower side of the mounting sleeve, the remaining mounting sleeves are slidably connected to the outside of the crossbeam, and the movable shovel body is fixedly connected to the lower side of the sliding mounting sleeve.

[0011] The two adjacent mounting sleeves are connected by a horizontal adjustment mechanism, which is fixedly connected to the mounting sleeve, and the piston rod of the horizontal adjustment mechanism on the mounting sleeve is fixedly connected to the adjacent mounting sleeve.

[0012] Furthermore, the drug release device includes a support body fixedly connected to the rear side of the mounting sleeve. Multiple discharge pipes are fixedly connected to the lower side of the support body. The discharge pipes are divided into an empty section and a spraying section. The spraying section is located at the lower end of the empty section. Multiple liquid outlet holes are opened on the peripheral side of the spraying section. A drug storage tank is fixedly connected to the upper side of the support body. A delivery pump is fixedly connected to the outside of the drug storage tank. The delivery pump and the discharge pipes are connected by a connecting pipe.

[0013] Furthermore, a sleeve is vertically slidably connected to the outer side of the discharge pipe, and a vertical adjustment mechanism is fixedly connected to the upper side of the support body. The piston rod of the vertical adjustment mechanism is drivenly connected to the sleeve.

[0014] Furthermore, the piston rod of the vertical adjustment mechanism is fixedly connected to the liquid outlet box, and multiple sleeves are fixedly connected to the liquid outlet box. The liquid outlet box is a hollow box body, and several nozzles are provided on the lower side of the hollow box body. Another delivery pump is also fixedly connected to the outside of the medicine storage tank, and the delivery pump is connected to the liquid outlet box through a connecting pipe.

[0015] Furthermore, an annular rubber sealing gasket is fixedly connected to the inner side of the sleeve.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-3 As shown, an integrated tillage-chemical slow-release device for remediation of heavy metal contaminated soil includes a tillage device and a chemical slow-release device. The tillage device includes a crossbeam 1, and multiple tillage shovels 3 are mounted on the lower side of the crossbeam 1. One tillage shovel 3 is a fixed shovel body that is fixedly connected to the lower side of the crossbeam 1, and the other tillage shovels 3 are movable shovel bodies that can move on the lower side of the crossbeam 1.

[0025] The crossbeam 1 is also equipped with an adjustment mechanism that is connected to multiple movable shovels. This mechanism drives the movable shovels to move along the axis of the crossbeam 1, thereby adjusting the distance between two adjacent tillage shovels 3 and controlling the tillage range of the tillage shovels 3. By adjusting the tillage range of multiple tillage shovels 3, the tillage width of the tillage equipment can be adjusted to meet different tillage needs.

[0026] like Figures 1-2 As shown, the adjustment mechanism includes multiple mounting sleeves 2, one of which is fixedly connected to the outside of the crossbeam 1, the fixed shovel body is fixedly connected to the lower side of the mounting sleeve 2, the remaining mounting sleeves 2 are slidably connected to the outside of the crossbeam 1, and the movable shovel body is fixedly connected to the lower side of the sliding mounting sleeve 2.

[0027] The two adjacent mounting sleeves 2 are connected by a horizontal adjustment mechanism 4. That is, the horizontal adjustment mechanism 4 is fixedly connected to the mounting sleeve 2, and the piston rod of the horizontal adjustment mechanism 4 on the mounting sleeve 2 is fixedly connected to the adjacent mounting sleeve 2. The horizontal adjustment mechanism 4 can be a linear moving device such as an electric push rod or a hydraulic cylinder, which can adjust the position of the tillage shovel 3 relatively easily.

[0028] like Figures 1-3 As shown, the pesticide slow-release device includes multiple pesticide slow-releasers, which are fixedly connected to the rear side of multiple tillage shovels 3, so that the pesticide slow-releasers can be moved synchronously when the tillage shovels 3 move, thereby adjusting the spraying range of the pesticide.

[0029] Specifically, the pesticide slow-release device includes a support body 5 fixedly connected to the rear side of the mounting sleeve 2. Multiple discharge pipes 7 are fixedly connected to the lower side of the support body 5. The discharge pipes 7 are divided into an empty section and a spraying section. The spraying section is located at the lower end of the empty section. Multiple liquid outlet holes 8 are opened on the peripheral side of the spraying section. A pesticide storage tank 6 is fixedly connected to the upper side of the support body 5. A delivery pump 12 is fixedly connected to the outside of the pesticide storage tank 6. The delivery pump 12 and the discharge pipes 7 are connected by a connecting pipe 13. When the tillage shovel 3 tills the soil, the discharge pipes 7 enter the tilled soil behind the tillage shovel 3. The delivery pump 12 is started to spray the pesticide inside the pesticide storage tank 6 into the discharge pipes 7, and then spray it through the liquid outlet holes 8.

[0030] In order to precisely control the spraying area of ​​the pesticide and ensure that the pesticide penetrates into the soil, a sleeve 9 is vertically slidably connected to the outside of the discharge pipe 7. When the sleeve 9 slides to the outside of the liquid outlet 8, it can block part of the liquid outlet 8 from top to bottom, adjust the range of pesticide discharge inside the discharge pipe 7, and thus control the spraying range height of the pesticide so that the spraying range height matches the depth of the discharge pipe 7 inserted into the soil.

[0031] An annular rubber sealing gasket is fixedly connected to the inner side of the sleeve 9. The annular rubber sealing gasket seals the gap between the sleeve 9 and the discharge pipe 7, thereby reducing the leakage of medicine between the sleeve 9 and the discharge pipe 7.

[0032] In order to drive the sleeve 9 to move vertically, a vertical adjustment mechanism 10 is fixedly connected to the upper side of the support body 5. The piston rod of the vertical adjustment mechanism 10 is connected to the sleeve 9 in a transmission connection, thereby driving the sleeve 9 to move.

[0033] The vertical adjustment mechanism 10 can also be used for linear mobile devices such as electric push rods and hydraulic cylinders.

[0034] The piston rod of the vertical adjustment mechanism 10 and the sleeve 9 are connected by a transmission connection. The piston rod of the vertical adjustment mechanism 10 is fixedly connected to the liquid outlet box 11, and multiple sleeves 9 are fixedly connected to the liquid outlet box 11. When the vertical adjustment mechanism 10 moves the liquid outlet box 11, it can move multiple sleeves 9 synchronously. At the same time, the liquid outlet box 11 is a hollow box with several nozzles on the lower side. Another delivery pump 12 is fixedly connected to the outside of the liquid storage tank 6. The delivery pump 12 is connected to the liquid outlet box 11 through the connecting pipe 13, so that the liquid can be delivered into the liquid outlet box 11 and sprayed onto the surface of the cultivated soil through the nozzles of the liquid outlet box 11. At this time, the liquid outlet box 11 and the discharge pipe 7 are used as two independent agent spraying systems to spray the agent into the soil and the soil surface respectively, which can better remediate the soil contaminated with heavy metals.

[0035] In summary, this technical solution integrates tillage equipment and pesticide slow-release equipment, enabling continuous tillage and pesticide addition to heavy metal contaminated soil. Furthermore, the working width of both the tillage and pesticide slow-release equipment can be adjusted according to user needs, thus adapting to different types of heavy metal contaminated soil.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
