Description

Technical Field

[0001] This invention belongs to the field of soil remediation technology, specifically referring to a soil remediation device for agricultural fields. Background Technology

[0002] Agricultural land refers to land used directly or indirectly for agricultural production. my country's arable land pollution is diverse and widely distributed, primarily consisting of heavy metals, organic pollutants, acid-base imbalance, and soil compaction. Some areas suffer from combined pollution, threatening agricultural product safety and the ecological environment. With industrial pollution and the misuse and overuse of pesticides, agricultural soil pollution has become a threat to the sustainable use of land resources and the ecological safety of agricultural products, necessitating urgent remediation and restoration of agricultural soil pollution. However, current soil remediation devices still have the following problems: 1. Some remediation devices only spray agents on the soil surface, making it difficult to penetrate into the root zone, and it is also difficult to adjust the soil turning depth when breaking up the soil. 2. Some soil remediation devices do not allow sufficient contact between the agents and pollutants, and it is difficult to treat heavy metals and organic pollutants simultaneously, resulting in low synergistic remediation efficiency. Summary of the Invention

[0003] To address the aforementioned challenges, this invention provides an agricultural soil remediation device that allows for convenient adjustment of tilling depth and rapid soil dispersal based on pollution levels. The device uses a hydraulic motor to directly adjust the depth of the dispersing components inserted into the soil, and the rotation of the loosening claw, auxiliary claw, and cutting blade thoroughly disperses the soil, facilitating subsequent chemical mixing. A pre-action principle combined with electromagnetic principles is employed in the mixing mechanism, which thoroughly mixes the chemical with the soil and then transfers it via a scraper. During this process, an adjustable magnetic field removes heavy metal particles from the soil, further enhancing the remediation efficiency for heavy metal pollution.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention provides an agricultural field soil remediation device, including a vehicle body, a connecting frame on the upper part of the vehicle body, support wheels on both sides of the vehicle body, a hydraulic motor symmetrically arranged on the upper part of one end of the vehicle body, a pressure telescopic column at the output end of the hydraulic motor, a pressure connecting plate connected to the lower end of the pressure telescopic column, an adjustable soil crushing mechanism on the pressure connecting plate, a liquid spraying mechanism, a transfer mechanism and a backfilling mechanism arranged sequentially along one end of the adjustable soil crushing mechanism on the inner side of the vehicle body, and a mixing treatment mechanism above the backfilling mechanism; The adjustable soil breaking mechanism penetrates deep into the soil to be treated and breaks up the clumps in the soil. Then, the broken soil is transported to the mixing treatment unit by the transfer mechanism to mix the agent with the soil and treat heavy metal pollution. During this process, the agent spraying mechanism sprays the agent evenly into the soil. Then, the backfilling mechanism treats the soil for organic pollution and returns the treated soil to the field.

[0005] Furthermore, the adjustable soil breaking mechanism includes a main power motor, a dispersing component, and a transmission belt. The main power motor is located on the upper part of the pressing connecting plate, and the dispersing component is arranged in a linear array on the lower part of the pressing connecting plate. The dispersing components are arranged in a linear array along the long side of the pressing connecting plate. The output end of the main power motor is connected to the dispersing component in the middle position, and the transmission belt is wound around the array of dispersing components.

[0006] Furthermore, the mixing and processing mechanism includes a spring-loaded support plate, a mixing column, and a processing rotating column. One end of the spring-loaded support plate is rotatably mounted on the inner side wall of the vehicle body, and the other end of the spring-loaded support plate is connected to the inner top wall of the vehicle body by spring-loaded springs on both sides. The mixing column is rotatably mounted on the upper part of the spring-loaded support plate and is arranged in a linear array along the long side of the spring-loaded support plate. The processing rotating column is rotatably mounted on the inner wall of the vehicle body and is located on the side of the mixing column close to the spring-loaded springs. Scrapers are evenly distributed around the outer wall of the processing rotating column, and the radius of the rotation trajectory of the scraper end is greater than the distance from the center of the processing rotating column to the spring-loaded support plate. When the scraper rotates and sweeps across the spring-loaded support plate, it pushes the spring-loaded support plate to rotate downwards, and the mixed soil is scraped up by the scraper. When the scraper rotates past the spring-loaded support plate, the spring-loaded support plate bounces up under the elastic action of the spring-loaded springs, causing the soil on it to bounce, which facilitates the transportation of the soil on the spring-loaded support plate.

[0007] Preferably, the mixing and processing mechanism further includes a receiving roller, which is rotatably mounted on the inner wall of the vehicle body and driven by a first motor. The receiving roller is located on the side of the array of mixing columns away from the processing rotating column. Long plates are evenly distributed around the outer wall of the receiving roller, and adjacent long plates are used for receiving materials. The mixing columns are arranged in a cross shape, with adjacent mixing columns interspersed with each other. A transmission gear is provided at the end of the mixing column that passes through the spring support plate. Adjacent transmission gears mesh with each other, and the transmission gear in the middle is driven by the mixing motor. The processing rotating column is driven by a second motor. The first motor and the second motor are embedded in the inner wall of the vehicle body. The scraper is L-shaped, and the scraper part of the scraper rotates from the spring support plate toward the mixing column. An electromagnetic plate is embedded in the inner side of the scraper. The magnitude of the magnetic field generated by the electromagnetic plate can be adjusted by adjusting the current intensity passed into the electromagnetic plate. The magnetic force of the electromagnetic plate can be adjusted according to the degree of heavy metal pollution in the soil to separate heavy metal particles in the soil.

[0008] Furthermore, the dispersing assembly includes a fixed insert, a rotating column, a connecting turntable, loosening claws, and a sleeve. The fixed insert is located at the lower part of the pressing connecting plate. The rotating column is rotatably sleeved on the upper end of the fixed insert. The rotating column at the middle position is connected to the output end of the main power motor. The transmission belt is wound around the rotating columns in the array. The connecting turntable is located at the lower end of the rotating column and is rotatably sleeved on the fixed insert. The loosening claws are evenly distributed around the lower part of the connecting turntable. The sleeve is rotatably sleeved on the outer wall of the fixed insert and is located on the inner side of the loosening claws. The lower end of the outer wall of the sleeve is evenly distributed with auxiliary claws. The lower ends of the fixed insert and the auxiliary claws are conical.

[0009] Furthermore, the inner side of the sleeve is provided with a movable cavity that does not penetrate along the circumferential direction. The outer wall of the fixed insertion post is evenly distributed with rotating teeth, which are positioned corresponding to the movable cavity. The outer wall of the sleeve is evenly distributed with side wall insertion rods, which are rotatably connected between the sleeve and the loosening claw. One end of the side wall insertion rod that penetrates the outer wall of the sleeve is provided with a follower gear, which is rotatably located in the movable cavity and meshes with the rotating teeth. The outer wall of the side wall insertion rod is evenly distributed with cutting blades, which are movably located between the sleeve and the loosening claw. The lower ends of the loosening claw, the fixed insertion post, and the auxiliary claw are on the same plane. In operation, the main motor starts, driving the central rotating column to rotate. This, in turn, drives other rotating columns in the array to rotate synchronously via a transmission belt. The connecting turntable connected to the rotating column drives the evenly distributed loosening claws to rotate, breaking up the soil. Driven by the loosening claws, the sleeve rotates on the fixed column via the side wall insert rod, which in turn drives the auxiliary claws to stir the soil. Meanwhile, the follower gear rotates relative to the fixed column, meshing with the rotating teeth and causing the side wall insert rod to rotate between the loosening claws and the sleeve. The cutting blade rotates to further break up the soil. Through a single power drive, the technology of multi-directional soil breaking is achieved, thoroughly breaking up clumps of soil and facilitating subsequent transportation and chemical mixing.

[0010] Furthermore, a retaining plate is inclinedly connected to one end of the pressing connecting plate near the transfer mechanism. Connecting rods are symmetrically arranged on both sides of the retaining plate. A scraper is connected to the lower end of the connecting rod. The lower end of the scraper is on the same plane as the lower end of the fixed insertion column. Furthermore, the transfer mechanism includes a transport roller, a follower roller, a spring roller, and a transfer belt. The transport roller is rotatably mounted on the inner wall of the vehicle body and is driven by a transport motor. The follower roller is rotatably connected to the lower part of the connecting rod. A sliding groove is provided through the inner wall of the vehicle body, located below the transport roller. The spring roller is rotatably mounted within the sliding groove, with both ends sliding within it. A tension spring connects both ends of the spring roller to the upper wall of the sliding groove. The transfer belt is wound around the transport roller, follower roller, and spring roller. When the depth of the fixed insertion post into the soil is adjusted, the connecting plate is simultaneously pressed. The scraper blade moves downward and inserts into the soil. During this process, the connecting rod drives the follower roller downward, thereby increasing the length of the transfer belt between the transport roller and the follower roller. Under the compression of the transfer belt, the spring roller moves upward in the sliding groove, and the tension spring is compressed to adapt to the change in the length of the transfer belt between the transport roller and the follower roller. Under the elastic action of the tension spring, the transfer belt remains taut. The outer side of the transfer belt is evenly distributed with shovel arc plates. The scraper blade shovels the soil broken by the dispersing component to the transfer belt, and the shovel arc plates shovel and transport it. The amount of soil shoveled by the shovel arc plates each time is easy to estimate. The rotating and fixed end of the spring support plate is located below the sliding groove.

[0011] Furthermore, the liquid spraying mechanism includes a medicine tank, a spray box, adjusting plates, and adjusting screws. The medicine tank is located on the upper part of the vehicle body. An agitator is rotatably installed inside the medicine tank and driven by an agitator motor. A liquid pump is connected to the lower part of the medicine tank. The spray box is located on the upper part of the retaining plate. A liquid pipe is connected between the spray box and the liquid pump. Transition chambers are evenly distributed and connected on the side of the spray box facing the transfer belt. Spray nozzles are connected to the transition chambers and face the transfer belt. The adjusting plates are slidably installed in the transition chambers, and the upper ends of the evenly distributed adjusting plates are connected. Adjusting screws are symmetrically arranged at both ends of the upper part of the spray box and are driven by an adjusting motor. Adjusting connecting plates are engaged on the adjusting screws and connected to the adjusting plates at both ends.

[0012] Furthermore, the backfilling mechanism includes a discharge hopper and a pressure roller. The discharge hopper is located below the spring-loaded support plate. One end of the discharge hopper near the transfer belt is rotatably connected to the inner wall of the vehicle body, and the other end of the discharge hopper drags on the ground. The pressure roller is rotatably located at the other end of the discharge hopper. Adsorption rollers are evenly distributed and rotated inside the discharge hopper. The adsorption rollers are driven by an adsorption motor and are made of activated carbon adsorption rods. The adsorption motor drives the adsorption rollers to rotate, which on the one hand adsorbs residual organic pollutants in the soil through activated carbon, and on the other hand transports the treated soil by rotating. Long nails and short nails are evenly distributed on the outer wall of the pressure roller. The long nails and short nails are staggered and are arranged in a linear array along the rotation axis of the pressure roller.

[0013] Preferably, the vehicle body is equipped with a main controller, which is a PLC controller. The main controller model is Siemens S7-300. The hydraulic motor, main power motor, first motor, second motor, mixing motor, electromagnetic plate, transport motor, stirring motor, liquid pump, regulating motor and adsorption motor are electrically connected to the main controller.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: 1. This invention provides an agricultural field soil remediation device. An adjustable soil-breaking mechanism penetrates deep into the soil to be treated and breaks up any clumps. The broken soil is then transported to a mixing and treatment mechanism for mixing with chemicals and treating heavy metal pollution. During this process, a chemical spraying mechanism evenly sprays chemicals onto the soil. Finally, a backfilling mechanism treats the soil for organic pollution and returns the treated soil to the field. This device combines physical and chemical remediation, integrating soil breaking, loading and transport, chemical spraying, pollutant screening, and soil backfilling into a single unit. It is easy to operate and improves the efficiency of soil remediation.

[0015] 2. Utilizing a pre-action principle, the set-up soil-dispersing component, while the loosening claw rotates and breaks up the soil, the sleeve rotates on the fixed insertion post driven by the side wall insertion rod. This causes the sleeve to drive the auxiliary claw to stir the soil, while the follower gear rotates relative to the fixed insertion post. This causes the follower gear to mesh with the rotating teeth, driving the side wall insertion rod to rotate between the loosening claw and the sleeve. The cutting blade rotates to further break up the soil. Through a single power drive, the technology achieves multi-directional soil breaking up, thoroughly breaking up clumps of soil, facilitating subsequent transportation and chemical mixing treatment.

[0016] 3. The mixing mechanism, which combines the principle of pre-action with electromagnetic principles, thoroughly mixes the agent with the soil and then transfers it via a scraper. During this process, as the scraper rotates and sweeps across the spring-loaded support plate, it pushes the plate downwards, lifting the mixed soil. When the scraper passes the spring-loaded support plate, the plate springs up under the elasticity of the spring spring, causing the soil on it to bounce, facilitating soil transport on the plate. Simultaneously, the magnetic field generated by the electromagnetic plate can be adjusted by regulating the current intensity flowing through it. The magnetic force of the electromagnetic plate can be adjusted according to the degree of heavy metal pollution in the soil, effectively sieving out heavy metal particles and further improving the remediation efficiency of heavy metal pollution.

The amount of soil shoveled by the soil-shoveling arc plates 47 each time is easy to estimate.

[0024] The liquid spraying mechanism 7 includes a medicine tank 31 and a spraying box 35. The medicine tank 31 is located on the upper part of the vehicle body 1. A stirring wheel 33 is rotatably installed inside the medicine tank 31. The stirring wheel 33 is driven by a stirring motor. A liquid pump 32 is connected to the lower part of the medicine tank 31. The spraying box 35 is located on the upper part of the retaining plate 17. A liquid pipe 34 is connected between the spraying box 35 and the liquid pump 32. Transition chambers 36 are evenly distributed and connected on the side of the spraying box 35 facing the transfer belt 46.

The upper ends of the evenly distributed adjusting plates 38 are connected. Adjusting screws 39 are symmetrically installed at both ends of the upper part of the spraying box 35. The adjusting screws 39 are driven by an adjusting motor. Adjusting connecting plates 40 are engaged on the adjusting screws 39 and connected to the adjusting plates 38 at both ends.

[0025] The mixing and processing mechanism 9 includes a spring-loaded support plate 48, a processing rotating column 54, and a receiving roller 52. One end of the spring-loaded support plate 48 is rotatably mounted on the inner side wall of the vehicle body 1, and the rotating and fixed end of the spring-loaded support plate 48 is located below the sliding groove 43. Spring-loaded springs 51 are connected to the inner top wall of the vehicle body 1 on both sides of the other end of the spring-loaded support plate 48. Mixing columns 53 are rotatably mounted on the upper part of the spring-loaded support plate 48. The mixing columns 53 are arranged in a linear array along the long side of the spring-loaded support plate 48, forming a cross-shaped column arrangement. The adjacent mixing columns 53 are interspersed with each other. The end of the mixing column 53 that passes through the spring support plate 48 is provided with a transmission gear 57.

The radius of the rotation trajectory of the scraper blade 55's end is greater than the distance from the center of the processing rotating column 54 to the spring support plate 48. The scraper blades 55 are L-shaped. The scraper portion of the scraper blade 55 rotates from the spring support plate 48 towards the mixing column 53. When the scraper blade 55 rotates and sweeps across the spring support plate 48, it pushes the spring... The support plate 48 rotates downwards, and the soil is scraped up by the scraper shovel 55. When the scraper shovel 55 rotates past the spring support plate 48, the spring support plate 48 springs up under the elastic action of the spring spring 51, causing the soil on it to bounce, which facilitates the transportation of the soil on the spring support plate 48. An electromagnetic plate 56 is embedded in the inner side of the scraper shovel 55. During the process of the scraper shovel 55 scraping and rotating to transport the soil, the soil slides over the electromagnetic plate 56. The magnitude of the magnetic field generated by the electromagnetic plate 56 can be adjusted by adjusting the current intensity passed into the electromagnetic plate 56. The magnetic force of the electromagnetic plate 56 can be adjusted according to the degree of heavy metal pollution in the soil to separate heavy metal particles in the soil.

[0026] The backfilling mechanism 8 includes a discharge hopper 11 and a pressure roller 12. The discharge hopper 11 is located below the spring support plate 48. One end of the discharge hopper 11 near the transfer belt 46 is rotatably connected to the inner wall of the vehicle body 1, and the other end of the discharge hopper 11 is dragged on the ground. The pressure roller 12 is rotatably located at the other end of the discharge hopper 11. Adsorption rollers 58 are evenly distributed and rotated inside the discharge hopper 11. The adsorption rollers 58 are driven by an adsorption motor and are made of activated carbon adsorption rods. Long nails 59 and short nails 60 are evenly distributed around the outer wall of the pressure roller 12. The long nails 59 and short nails 60 are staggered and are arranged in a linear array along the rotation axis of the pressure roller 12.

[0027] The main controller is installed on the vehicle body 1. The main controller adopts a PLC controller and the model of the main controller is Siemens S7-300. The hydraulic motor 3, the main power motor 15, the first motor 49, the second motor 50, the mixing motor, the electromagnetic plate 56, the transport motor, the stirring motor, the liquid pump 32, the regulating motor and the adsorption motor are electrically connected to the main controller.

[0028] Working principle and workflow: In practical use, the staff installs the device on the back of the tractor through the connecting frame 10, and the tractor drives the device to move in the farmland; then the depth and type of soil pollution are measured, the downward movement distance of the adjustable soil crushing mechanism 5 is set, and the prepared medicine solution is poured into the medicine tank 31; the heavy metal content of the soil is detected, the current flowing through the electromagnetic plate 56 is set, and then the main controller is started to carry out soil remediation work.

[0029] Hydraulic motor 3 starts, causing the pressing telescopic column 4 to extend. According to the set distance, the adjustable soil crushing mechanism 5 is pressed down into the soil as a whole. The lower ends of the fixed insertion column 20, loosening claw 23 and auxiliary claw 25 are inserted into the soil. Simultaneously, the pressing connecting plate 13 drives the scraper 19 to move down and insert into the soil. During this process, driven by the connecting rod 18, the follower roller 41 moves down, thereby increasing the length of the transfer belt 46 between the transport roller 42 and the follower roller 41. Under the compression of the transfer belt 46, the elastic roller 44 moves up in the sliding groove 43, and the tension spring 45 is compressed to adapt to the change in the length of the transfer belt 46 between the transport roller 42 and the follower roller 41. Under the elastic action of the tension spring 45, the transfer belt 46 remains taut.

[0030] After the insertion depth of the adjustable soil-crushing mechanism 5 is adjusted, the tractor pulls the device forward, the main power motor 15 starts, drives the rotating column 21 in the middle position to rotate, and drives the rotating columns 21 in other arrays to rotate synchronously through the transmission belt 16. The connecting turntable 22 connected to the rotating column 21 drives the evenly distributed loosening claws 23 to rotate, crushing the soil. Driven by the loosening claws 23, the sleeve 24 rotates on the fixed insertion column 20 through the side wall insertion rod 26, which in turn drives the auxiliary claws 25 to stir the soil. The follower gear 29 rotates relative to the fixed insertion column 20, which in turn meshes with the rotating teeth 28, driving the side wall insertion rod 26 to rotate between the loosening claws 23 and the sleeve 24. The cutting blade 27 rotates to further crush the soil, making the clumps of soil completely broken up, which is convenient for subsequent transportation and chemical mixing.

[0031] Synchronously, as the device moves, the broken soil is scraped by the scraper 19 to the transfer mechanism 6. The transport motor drives the transport roller 42 to rotate. Driven by the transfer belt 46, the spring roller 44 and the follower roller 41 rotate synchronously. The shovel arc plate 47 shovels soil as the transfer belt 46 rotates. The amount of soil shoveled by each shovel arc plate 47 in a single operation is fixed, making it easy to estimate the amount of soil transported by each shovel arc plate 47, and thus easier to control the amount of pesticide sprayed according to the degree of soil contamination. During the soil transfer process, the nozzle 37 sprays pesticide onto the soil transported between the transport roller 42 and the follower roller 41. Since the amount of soil shoveled by the shovel arc plate 47 in a single operation is limited, the sprayed pesticide can act as evenly as possible on the soil. Compared to concentrated spraying on the surface of accumulated soil, the injection efficiency and spray uniformity of the agent are higher. Specifically, the stirring motor drives the stirring wheel 33 to rotate, stirring the liquid in the medicine tank 31 to prevent the agent from settling. The liquid pump 32 works and draws the agent from the medicine tank 31 to the spraying box 35 through the liquid pumping pipe. According to the degree of soil pollution, the adjusting screw 39 is rotated by the adjusting motor, which in turn moves the adjusting connecting plate 40 up and down, thereby driving the adjusting insert plate 38 to move up and down in the transition cavity 36, adjusting the connecting space in the transition cavity 36, and controlling the amount of agent sprayed. During the operation of the transfer mechanism 6, the nozzle 37 sprays the agent onto the soil on the shovel arc plate 47, and the agent and soil initially mix and react.

[0032] After the shovel plate 47 rotates past the transport roller 42, the soil inside the shovel plate 47 falls under the action of gravity and lands on the receiving roller 52. Driven by the first motor 49, the receiving roller 52 rotates, transporting the soil to the mixing column 53. The mixing motor drives the transmission gear 57 in the middle to rotate, and the meshing transmission gears 57 rotate synchronously, thereby causing the cross-shaped and interspersed mixing columns 53 to rotate. Adjacent mixing columns 53 rotate in opposite directions, stirring the soil between them, increasing the contact area between the agent and the soil, and making the two fully mixed. At the same time, the second motor 50 drives the processing column 54 to rotate, thereby causing the scraper part of the scraper shovel 55 to rotate from the spring support plate 48 towards the mixing column 53. When the scraper shovel 55 rotates and sweeps across the spring support plate 48... When the spring-loaded support plate 48 is pushed to rotate downwards, the mixed soil is scraped up by the scraper shovel 55. When the scraper shovel 55 rotates past the spring-loaded support plate 48, the spring-loaded support plate 48 bounces up under the elastic action of the spring spring 51, causing the soil on it to bounce along with it. This causes the soil at the mixing column 53 to bounce and turn over while being mixed, which also facilitates the transport of the soil on the spring-loaded support plate 48. The electromagnetic plate 56 embedded in the inner side of the scraper shovel 55 generates magnetism when energized. During the process of the scraper shovel 55 scraping and rotating to transport the soil, the soil slides over the electromagnetic plate 56. The intensity of the current passing through the electromagnetic plate 56 is adjusted according to the degree of heavy metal pollution in the soil, thereby adjusting the magnitude of the magnetic field generated by the electromagnetic plate 56, strengthening or weakening the magnetic force of the electromagnetic plate 56, and further separating the heavy metal particles in the soil.

[0033] The soil transported by the rotating scraper 55 finally falls onto the adsorption roller 58 in the discharge hopper 11. The adsorption motor drives the adsorption roller 58 to rotate. On the one hand, the activated carbon adsorbs the residual organic pollutants in the soil, and on the other hand, the rotating roller transports the treated soil. During the movement of this device, the pressure roller 12 rotates adaptively on the ground. When the pressure roller 12 rotates, the long nails 59 and short nails 60 are intermittently inserted into the ground, which causes the discharge hopper 11 to shake behind the vehicle body 1, which facilitates the backfilling of soil. At the same time, the backfilled soil is pressed and shaped by the pressure roller, and the long nails 59 and short nails 60 help to loosen the soil and ventilate it.

[0034] It is worth noting that the control of the hydraulic motor 3, the main power motor 15, the first motor 49, the second motor 50, the mixing motor, the transport motor, the stirring motor, the liquid pump 32, the regulating motor and the adsorption motor are all existing technologies, and will not be described in detail here.
