Description

Technical Field

[0001] This invention belongs to the technical field of soil remediation devices, specifically relating to a contaminated soil remediation device. Background Technology

[0002] Soil pollutants can be broadly classified into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements such as cesium and strontium, and compounds containing arsenic, selenium, and fluorine. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, and harmful microorganisms from urban sewage, sludge, and manure. When the soil contains excessive amounts of harmful substances, exceeding its self-purification capacity, changes occur in the soil's composition, structure, and function. Microbial activity is inhibited, and harmful substances or their decomposition products gradually accumulate in the soil. These substances are then indirectly absorbed by the human body through the pathway of "soil → plants → human body" or "soil → water → human body," eventually reaching a level that harms human health—this is soil pollution.

[0003] The main reasons for soil acidity are as follows: 1. Carbonic acid in rainwater; 2. Metabolic products of microorganisms and plant roots; 3. Organic acids produced during the decomposition of organic matter; 4. Sulfuric acid produced by the oxidation of ferrous sulfide; 5. Decomposition of chemical fertilizers.

[0004] For acidic soils, lime powder is often used to neutralize acidic substances and prevent excessive alkalization, making it suitable for large-scale application. However, lime powder is usually in powder form and can only come into contact with the soil surface, not the underlying soil layers. This affects the full progress of the neutralization reaction and hinders the soil acidity remediation effect. Furthermore, the application process is generally done manually, which is inefficient and makes it impossible to control the lime powder dosage over a long period. If the dosage is not balanced, it can also affect the soil's pH balance. Summary of the Invention

[0005] The purpose of this invention is to provide a contaminated soil remediation device to solve the technical problem that lime powder is usually in powder form, which can only contact the soil surface and cannot effectively contact the underlying soil, thus affecting the full progress of the neutralization reaction and hindering the remediation effect of soil acidity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A contaminated soil remediation device, comprising:

[0008] The neutralization reaction mechanism includes baffles fixed to both sides of the bottom of the trolley. A first motor is fixedly installed on the baffles. The output shaft of the first motor passes through the baffles and extends to the rotating drum. A second motor is installed at one end of the side wall of the rotating drum. The output shaft of the second motor is connected to a first rotating tooth. The first rotating tooth meshes with an alternately distributed first gear plate in the length direction. A bucket extending to the outside of the rotating drum is installed on the first gear plate. Adjacent buckets are fixedly connected by a crossbeam.

[0009] The output shaft of the first motor and the movable shaft on the guide box are connected by a first conveyor belt. A retaining ring is fixedly installed at one end of the movable shaft, and a rotating sleeve placed inside the guide box is connected to the other end. The outer wall of the rotating sleeve is connected with a ring-shaped first baffle plate. The arc-shaped surfaces of the first baffle plate near the outer wall of the guide tube are connected with matching arc-shaped parts.

[0010] Furthermore, the upper part of the arc-shaped portion moves against the lifting plate, the lifting plate and the fixed block on the side wall of the guide tube are connected by a first spring, and both ends of the lifting plate and the second baffle are connected by a swing rod. A second gear plate placed inside the fixed block is fixedly connected to one end of the second baffle. A third gear plate is driven by a second rotating tooth on the second gear plate. One end of the third gear plate is fixed to the third baffle.

[0011] Furthermore, the third gear plate and the second gear plate are arranged in parallel vertically, and a movable cavity is formed between the second gear plate, the third gear plate and the side wall of the fixed block. The top of the fixed block is triangular and is connected to the side wall of the guide tube by locking it with a positioning pin. Both ends of the swing rod are mounted on the lifting plate and the second shielding plate by rotational connection.

[0012] Furthermore, the trolley is provided with a guide trough placed between the guide tube and the rotating drum, the top of the guide box is cone-shaped and filled with lime powder, a first metering cavity is formed between the second baffle plate, the third baffle plate and the side wall of the fixed block, a second metering cavity is formed between the first baffle plate and the arc-shaped surface, and a rotating groove connected to the movable shaft is provided on the guide tube.

[0013] Furthermore, it also includes a particle removal mechanism, which includes electric guide rails fixed on both sides of the top of the frame. U-shaped blocks are movably connected to the electric guide rails. The U-shaped blocks are fixedly connected to each other through a panel. A cylinder is fixedly installed on the panel. One end of the piston rod on the cylinder passes through the panel and extends to the third motor, while the other end extends to the side plate.

[0014] Furthermore, one end of the output shaft of the third motor is fixedly connected to a first annular plate, the first annular plate and the second annular plate are connected by an arc plate, the outer edge of the second annular plate is provided with an annular groove placed on the side plate, and the arc plate is provided with equidistantly distributed first filter holes.

[0015] Furthermore, a first rotating shaft is provided below the arc-shaped plate, positioned between the rollers on the trolley. The first rotating shaft and a second rotating shaft on the frame are connected by a second conveyor belt. A cam is fixedly installed on the second rotating shaft. The cam moves against a movable plate in the strip frame. The movable plate and the extended end on the strip frame are connected by a second spring.

[0016] Furthermore, the movable plate is connected to a limiting groove along the height direction of the side wall of the strip frame, and a second filter hole is opened on the movable plate and a conical top rod corresponding to the first filter hole is integrally installed. Both ends of the strip frame are installed on the frame by fixing rods.

[0017] Furthermore, the trolley is fixedly equipped with a handle, and the arc-shaped part is made of elastic rubber or resin.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] (1) In this invention, the trolley is moved to the soil location point by the push of the handle. During the movement, it is convenient to repair acidic soil and effectively remove large particles of stone in the soil, thereby effectively repairing the soil and improving soil quality.

[0020] (2) In this invention, after the first motor starts, it can drive the rotating drum to rotate. In conjunction with the second motor, under the action of gear meshing transmission, the bucket can extend in different directions on the rotating drum. Moreover, the buckets are staggered and spaced apart. During the rotation of the rotating drum, it can effectively excavate soil at different depths according to actual needs. This ensures that the lime powder and soil are in full contact, guaranteeing the stable progress of the neutralization reaction. In addition, under the transmission connection of the first conveyor belt, the power is transmitted to the rotating sleeve. The rotating sleeve divides the rotation through the annular first baffle plate, which can both control the introduced lime powder. The system serves both to divide and measure the lime powder, and to prevent excessive lime powder output that would hinder even distribution. During rotation, the first baffle plate, due to its active resistance and the elastic restoring force of the first spring, moves up and down. Through the rotational connection of the swing rod and the gear meshing, the third and second baffle plates at the upper and lower ends move horizontally in opposite directions, forming the first metering chamber. This further meters and transports the lime powder, ensuring the stability of the lime powder distribution and allowing it to be effectively and evenly distributed into the soil, thus guaranteeing the effectiveness of the neutralization reaction.

[0021] (3) In this invention, during the start-up of the third motor, the arc-shaped plate can be positioned directly over the soil and initially filtered through the first filter hole. The cylinder can drive the particle removal mechanism to move up and down, and move horizontally under the push of the electric guide rail. Then, during the position change, the arc-shaped plate pours the soil into the strip frame through a flipping operation. At this time, the rollers on the trolley drive the first rotating shaft to rotate during rotation. Then, under the action of mechanical transmission, the rotational motion of the cam, combined with the elastic return action of the second spring, can be converted into the up and down movement of the moving plate. During the up and down movement of the moving plate, the soil can be filtered through the second filter hole. The secondary filtration process allows the screened soil to fall directly onto the ground through the second filter holes. Furthermore, the moving plate's up-and-down movement drives the synchronous movement of the conical push rod, which ejects the first filter holes on the arc-shaped plate, preventing clogging. Driven by a third motor, the arc-shaped plate rotates, allowing the conical push rod to eject the first filter holes at different positions, effectively removing any clogging stones. This device is rationally designed, highly integrated, ensures safe operation, and significantly improves its applicability. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference manual attached Figure 1 - Appendix Figure 9 As shown, a contaminated soil remediation device includes:

[0035] Neutralization reaction mechanism 1 includes baffles fixed on both sides of the bottom end of the trolley 2. A first motor 3 is fixedly installed on the baffles. The output shaft of the first motor 3 passes through the baffles and extends to the rotating drum 4. A second motor 5 is installed on one end of the side wall of the rotating drum 4. The output shaft of the second motor 5 is connected to the first rotating tooth 6. The first rotating tooth 6 meshes with the staggered first gear plate 7 in the length direction. A bucket 8 extending to the outside of the rotating drum 4 is installed on the first gear plate 7. Adjacent buckets 8 are fixedly connected by a crossbeam 9.

[0036] The output shaft of the first motor 3 and the movable shaft on the guide box 10 are connected by the first conveyor belt 11. A retaining ring 12 is fixedly installed at one end of the movable shaft, and a rotating sleeve 13 placed inside the guide box 10 is connected to the other end. The outer wall of the rotating sleeve 13 is connected to a ring-shaped first baffle plate 14. The arc-shaped surfaces of the first baffle plate 14 near the outer wall of the guide tube are connected to arc-shaped parts 15 that are adapted to it.

[0037] Pushed by handle 46, the cart 2 moves to the soil location. During the movement, it facilitates the remediation of acidic soil and the effective removal of large particles such as stones in the soil, thereby effectively remediating the soil and improving soil quality.

[0038] Specifically, in order to ensure that lime powder can fully contact the soil at different depths, thus facilitating the improvement of soil acidity, this invention features an adjustable length for the bucket 8. This allows for digging at different soil depths during the rotation of the bucket 8. During startup, the second motor 5 drives the first rotating gear 6 to rotate. Under the action of gear meshing, the first gear plates 7, which are staggered around the perimeter, can move outward or inward simultaneously. Moreover, the staggered positional relationship can fully utilize the space on the outer surface of the rotating drum 4, further ensuring that the bucket 8 makes full contact with the soil.

[0039] The feed box 10 can be used to store and discharge lime powder. In other words, lime water can come into direct contact with soil at different depths through flow and infiltration. However, lime water is not used for the following reasons: Lime water is a strong alkaline substance. Excessive use can easily lead to soil compaction, damage the biodiversity in the soil, and may even cause soil degradation. Moreover, lime water combines with elements such as iron and magnesium in the soil to form precipitates, which hinder the absorption of these elements by crops, resulting in yellowing of leaves and stunted growth.

[0040] The upper part of the arc-shaped section 15 moves against the lifting plate 16. The lifting plate 16 and the fixed block 17 on the side wall of the guide tube are connected by the first spring 18. Both ends of the lifting plate 16 and the second baffle plate 19 are connected by the swing rod 20. One end of the second baffle plate 19 is fixedly connected to the second gear plate 21 placed inside the fixed block 17. The second gear plate 21 is driven by the second rotating tooth 22. The third gear plate 23 is meshed on the second gear plate 21. One end of the third gear plate 23 is fixed on the third baffle plate 24.

[0041] The third gear plate 23 and the second gear plate 21 are arranged in parallel vertically, and the second gear plate 21, the third gear plate 23 and the side wall of the fixing block 17 together form a movable cavity. The top of the fixing block 17 is triangular and is connected to the side wall of the guide tube by locking it with a positioning pin. Both ends of the swing rod 20 are mounted on the lifting plate 16 and the second shielding plate 19 by rotational connection.

[0042] The trolley 2 has a guide trough placed between the guide tube and the rotating drum 4. The top of the guide box 10 is cone-shaped and filled with lime powder. A first metering cavity 25 is formed between the second baffle 19, the third baffle 24 and the side wall of the fixing block 17. A second metering cavity 26 is formed between the first baffle 14 and the arc surface. The guide tube has a rotating groove connected to the movable shaft.

[0043] The arc-shaped surface on the conduit ensures the normal rotation of the arc-shaped part 15 on the first baffle 14. The arc-shaped part 15 is ring-shaped during rotation, so the arc-shaped surface on the conduit allows it to rotate effectively. At the same time, the arc-shaped part 15 made of elastic material can increase the buffering effect when it is rotated and subjected to pressure.

[0044] After the first motor 3 starts, it drives the rotating drum 4 to rotate. In conjunction with the second motor 5, and through gear meshing, the buckets 8 can extend in different directions on the rotating drum 4. The buckets 8 are staggered, allowing for effective excavation of soil at different depths as needed during drum 4 rotation. This ensures sufficient contact between the lime powder and the soil, guaranteeing a stable neutralization reaction. Furthermore, the power is transmitted to the rotating sleeve 13 via the first conveyor belt 11. The rotating sleeve 13, through the segmented rotation by the annular first baffle plate 14, effectively divides the introduced lime powder. The metering function also prevents excessive lime powder output, which would hinder uniform distribution. During rotation, the first baffle plate 14, due to the action of moving contact and the elastic restoring force of the first spring 18, causes the lifting plate 16 to move up and down. Through the rotational connection of the swing rod 20 and the gear meshing transmission, the third baffle plate 24 and the second baffle plate 19 at the upper and lower ends move back and forth horizontally in opposite directions, thus forming the first metering cavity 25. This further meters and transports the lime powder, ensuring the stability of lime powder distribution and enabling the lime powder to be effectively and evenly distributed into the soil, thus ensuring the effectiveness of the neutralization reaction.

[0045] The particle removal mechanism 27 includes electric guide rails 28 fixed on both sides of the top of the frame. U-shaped blocks 29 are movably connected to the electric guide rails 28. The U-shaped blocks 29 are fixedly connected to each other through a panel. A cylinder 30 is fixedly installed on the panel. One end of the piston rod of the cylinder 30 passes through the panel and extends to the third motor 31, while the other end extends to the side plate 32.

[0046] The driving principle of the electric guide rail 28 on the frame is as follows: the electric motor drives the guide rail to move linearly through the transmission device. The sensor monitors the position and speed of the guide rail in real time and feeds the information back to the controller. The controller controls the electric motor according to the information fed back by the sensor, so as to realize the automated movement and precise positioning of the guide rail. The specific transmission structure is a conventional technical means for those skilled in the art, and will not be described in detail here, nor is there a corresponding figure. However, it does not affect the implementation of the technical solution of the present invention.

[0047] During the startup of the third motor 31, the arc-shaped plate 35 can be flipped over to pour soil onto the surface, and initial filtration is achieved through the first filter hole 36. The cylinder 30 can drive the particle removal mechanism 27 to move up and down, and move horizontally under the push of the electric guide rail 28. During the position change, the arc-shaped plate 35 pours the soil into the strip frame 41 through the flipping operation. At this time, the roller on the trolley 2 drives the first rotating shaft 37 to rotate during the rotation. Then, under the action of mechanical transmission, the rotational motion of the cam 40, combined with the elastic return action of the second spring 43, can be converted into the up and down movement of the moving plate 42. During the up and down movement of the moving plate 42, the soil can be filtered through the second filter hole 44. After secondary filtration, the screened soil can fall directly onto the ground through the second filter hole 44. In addition, the moving plate 42 can drive the conical push rod 45 to move synchronously when it moves up and down. This can push out the first filter hole 36 on the arc plate 35 and prevent the first filter hole 36 on the arc plate 35 from becoming blocked. Moreover, under the drive of the third motor 31, the arc plate 35 can be rotated, so the conical push rod 45 can push out the first filter hole 36 at different positions, effectively removing the blocked stones. The device is reasonably designed, highly integrated, ensures the safe operation of the device, and effectively improves the applicability of the equipment.

[0048] One end of the output shaft of the third motor 31 is fixedly connected to a first annular plate 33. The first annular plate 33 and the second annular plate 34 are connected by an arc plate 35. The outer edge of the second annular plate 34 is provided with an annular groove on the side plate 32. The arc plate 35 is provided with equidistantly distributed first filter holes 36. Below the arc plate 35 is a first rotating shaft 37 placed between the rollers on the trolley 2. The first rotating shaft 37 and the second rotating shaft 38 on the frame are connected by a second conveyor belt 39. A cam 40 is fixedly installed on the second rotating shaft 38. The cam 40 moves against the moving plate 42 in the strip frame 41. The moving plate 42 and the extension end on the strip frame 41 are connected by a second spring 43.

[0049] The first rotating shaft 37 and the second rotating shaft 38 on the frame are not only for transmitting force to the cam 40, but also for compensating and adjusting the transmission distance, preventing the cam 40 from directly contacting the soil during rotation and hindering its movement, and also allowing the cam 40 to move and contact the moving plate 42 during rotation, thereby converting the rotational motion into the up-and-down linear motion of the moving plate 42.

[0050] Specifically, cylinders 30 are provided at both ends of the panel. The piston rod of one cylinder 30 is fixed to the housing of the third motor 31, and the piston rod of the other cylinder 30 is mounted on the side plate 32. This design can not only drive the overall movement of the screening component, but also allow the force of the third motor 31 to be transmitted to the arc plate 35. The annular groove on the side plate 32 can provide support for the second annular plate 34 on the arc plate 35, and can also prevent the second annular plate 34 from deviating in position during rotation.

[0051] The movable plate 42 is connected to the limit groove along the height direction of the side wall of the strip frame 41, and the movable plate 42 is provided with a second filter hole 44 and is integrally formed with a conical top rod 45 corresponding to the first filter hole 36. Both ends of the strip frame 41 are installed on the frame through fixing rods. The trolley 2 is fixedly installed with a handle 46, and the arc part 15 is made of elastic rubber or resin.
