Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, specifically to a soil improvement and remediation device and method. Background Technology

[0002] Ridging is a common form of farmland cultivation in agricultural production. Ridging improves soil drainage, increases soil temperature, and promotes crop root growth, thereby increasing crop yield. However, long-term use of ridge cultivation can lead to a series of problems, including soil structure damage, decreased fertility, and increased pest and disease activity. Soil improvement and restoration of ridged fields are particularly important in areas with poor soil and low organic matter content.

[0003] Soil remediation technology, as an effective means of controlling and improving soil pollution, has received widespread attention and application in recent years. Through physical, chemical, and biological methods, pollutants in soil can be transferred, absorbed, degraded, and transformed, thereby reducing their concentration or converting them into harmless substances. This reduces their mobility and bioavailability in the environment, ultimately lowering the concentration of harmful substances in the soil.

[0004] Currently, the remediation process for ridged soils mostly follows a fixed pattern: first, plowing is performed to loosen and level the soil; then, tilling is done to further break up soil compaction and increase soil looseness; next, soil conditioner or nutrient solution is sprayed to improve soil fertility and resistance to pests and diseases; finally, tilling is done again to ensure that the conditioner is fully and evenly mixed with the soil. While this process can improve soil conditions to some extent, it suffers from problems such as low efficiency, high energy consumption, cumbersome procedures, and uneven improvement effects. Crucially, in existing remediation processes, plowing, tilling, and conditioner spraying are often performed in separate steps. This not only prolongs the operation cycle and increases labor costs, but repeated tilling may also lead to excessive damage to soil structure, hindering the restoration of soil microecological balance.

[0005] Therefore, it is necessary to study a device and method that can efficiently and accurately complete the soil remediation and improvement of ridged land. Summary of the Invention

[0006] Therefore, the purpose of this invention is to provide a soil improvement and remediation device and method that effectively solves the problems of long labor cycle, low work efficiency and uneven improvement effect in existing ridging techniques.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a soil improvement and remediation device, comprising a frame, and a plow and a tillage and remediation mechanism mounted on the frame. The plow is fixedly installed in the middle of the frame and has furrows capable of turning the soil to the left and right sides. The tillage and remediation mechanism is symmetrically arranged on the left and right sides of the plow. The tillage and remediation mechanism includes a support frame, a distribution hopper, a lifting belt, a spraying assembly, and a screw conveyor assembly. The screw conveyor assembly includes a mixing cylinder, a discharge chamber, and a discharge plate. The mixing cylinder is fixedly installed longitudinally at the bottom of the support frame. The front end of the mixing cylinder has a feed inlet, and the rear end of the mixing cylinder has a discharge outlet. An auger is installed inside the mixing cylinder. The discharge chamber is fixedly installed above the mixing cylinder and communicates with it. The distribution hopper... The inlet faces the plow, and the lifting belt is inclined between the plow and the distribution hopper, connecting with the inlet of the distribution hopper. When the plow is working on the ridge, the lifting belt can transport the soil allocated to both sides into the distribution hopper. The bottom outlet of the distribution hopper is vertically downward facing the discharge plate. The discharge plate is installed between the distribution hopper and the discharge chamber, and its outer end extends downward into the discharge chamber. The spraying assembly includes several nozzles and a supply assembly for supplying pesticide to the nozzles. The supply assembly is located on a support frame outside the distribution hopper, and several nozzles are fixedly installed on the outside of the distribution hopper, facing the discharge plate. Thus, each nozzle can spray pesticide onto the soil falling from the outlet of the distribution hopper onto the discharge plate. The sprayed soil slides downward into the mixing cylinder.

[0008] Furthermore, the support frame is symmetrically installed on the vehicle frame, and the mixing cylinder is fixedly installed longitudinally at the bottom of the support frame by angle steel. An arc-shaped shovel plate is welded and fixed at the front end of the mixing cylinder, and the arc-shaped shovel plate is connected to the inlet of the mixing cylinder to form a feed port.

[0009] Furthermore, the discharge port on the mixing cylinder is inclined inward; a drive motor is fixedly installed at the rear end of the mixing cylinder, and the drive motor is connected to the inner rotating shaft of the auger.

[0010] Furthermore, the spray assembly includes a spray frame, a medicine tank, a water pump, several nozzles, and water pipes. The medicine tank, water pump, and nozzles are all mounted on the outer support frame of the spray frame. Several nozzles are fixedly installed on the inner end of the spray frame and face the unloading plate. One end of the water pump is connected to the medicine tank on the spray frame, and the other end is connected to each nozzle through a water pipe.

[0011] Furthermore, the lifting assembly includes a lifting belt, a lifting frame, and a lifting motor. The lifting frame is fixed vertically to the inner bottom of the support frame in a transverse direction. A vertical frame is fixed to the outer end of the lifting frame in an axial direction. The top and bottom of the lifting belt are respectively connected to the inner end of the vertical frame and the lifting frame via rotating shafts. A lifting motor is also fixed on one side wall of the lifting frame, and the output shaft of the lifting motor is connected to the rotating shaft at the bottom of the lifting belt.

[0012] Furthermore, the material distribution hopper includes a material distribution hopper cavity, a vibrating motor, an arc plate, a spring seat, and a top frame. The material distribution hopper cavity has material distribution holes evenly distributed inside. Arc plates are fixedly welded to the front and rear edges of the hopper cavity. A vibrating motor is fixedly installed inside the material distribution hopper cavity. The top and bottom of the motor are fixedly connected to the support frame through spring seats.

[0013] Furthermore, the arc plate on the rear side of the material distribution hopper is higher than the front side, and a screen plate is fixedly installed on the top of the two arc plates.

[0014] Furthermore, the screen plate has an inclined and arc-shaped bent structure and is connected to the end of the lifting belt. The front side of the screen plate extends forward to the outside of the distribution hopper, and screening holes are evenly opened on the plate body.

[0015] Furthermore, a dispersing assembly is provided above the lifting belt. The dispersing assembly includes a vertical frame, a drive wheel, a roller, a belt, and a driven wheel. The drive wheel is fixedly mounted on the rotating shaft of the lifting belt. The front end of the lifting frame is fixedly mounted on a vertical frame along the axial direction. A rotating shaft is rotatably mounted on adjacent vertical frames. The roller is fixedly mounted on the rotating shaft. One end of the rotating shaft extends out of the vertical frame and is fixedly mounted on a driven wheel. A belt is driven onto the drive wheel and the driven wheel, and dispersing teeth are evenly distributed on the roller.

[0016] The present invention also provides a soil improvement and remediation method, which utilizes the above-mentioned soil improvement and remediation device and includes the following steps:

[0017] Step 1: Connect the plow and tillage repair mechanism to the frame and load them onto the agricultural machinery.

[0018] Step 2: Adjust the position of the plow and support frame according to the distance between the ridge and the furrow, ensuring that the plow is placed in the middle of the ridge and the feed inlets of the mixing cylinders on both sides correspond to the furrow. Then, tighten the plow and support frame to the vehicle frame.

[0019] Step 3: Drive the agricultural machinery along the ridges, and simultaneously start the lifting motor and the vibration motor. The plow first turns over the ridges, and its plowshare turns the soil on the ridges to both sides. The lifting belt transports the soil distributed to both sides of the ridges to the distribution hopper. At the same time, the soil in the furrows is scooped up by the arc-shaped shovel at the front end of the mixing cylinder and put into the mixing cylinder.

[0020] Step 4: As the lifting belt works, it synchronously drives the rollers to rotate, thereby breaking up the soil on the lifting belt through the dispersing teeth on the rollers;

[0021] Step 5: Start the water pump to spray the pesticide from the nozzle of the spray assembly, spraying the soil falling from the outlet of the distribution hopper onto the discharge plate. The sprayed soil slides down the discharge plate into the mixing cylinder, where it is mixed with the furrow soil under the action of the auger. The soil mixed in the mixing cylinder is discharged from the outlet to the inside of the furrow.

[0022] Step 6: After completing the soil improvement and restoration of farmland, the tillage and restoration mechanism can be removed from the agricultural machinery and driven to drive the plow to carry out separate plowing operations, turning the ridges over and mixing them with the original furrows to form new ridge fields.

[0023] The beneficial effects of the above technical solution are as follows: The soil improvement and remediation device provided by this invention can spray soil conditioner on both the raised beds and furrows, allowing for targeted repair and improvement of the soil in both areas. After spraying the conditioner, a ridging machine is used for plowing, turning the raised beds over and mixing them with the original furrows. This ensures that the conditioner in the soil is fully and evenly distributed, while simultaneously transforming the original raised beds into furrows and the original furrows into new raised beds. This not only repairs and improves the soil but also makes the newly ridged soil more nutritious and fertile, without requiring excessive tillage steps. This increases crop yield and quality, effectively reduces the probability of soil structure damage, and improves soil quality protection.

[0024] The device of this invention integrates plowing, tilling, soil conditioner spraying and mixing into one unit, reducing operation steps and energy consumption, while ensuring effective mixing of the soil conditioner with the soil and improving the improvement effect. Through the integrated operation process, the soil remediation process of ridged land is optimized, realizing rapid and efficient soil improvement and providing a better soil environment for crop growth.

Detailed Implementation

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0039] Example 1: This example aims to provide a soil improvement and remediation device, mainly used for directly tilling and remediating the soil in ridged farmland after crop harvesting. In existing technologies, the improvement and remediation of ridged soil primarily employs methods such as manual fertilization, deep loosening, and crop rotation / fallowing. While these methods can improve soil quality to some extent, they suffer from drawbacks such as cumbersome operation, low efficiency, and uneven improvement effects. Especially for large-scale farmland, manual improvement methods are not only time-consuming and labor-intensive but also difficult to guarantee consistent improvement results. The soil improvement and remediation device provided by this invention can not only remediate and improve the soil but also transform newly ridged fields into more nutrient-rich and fertile soil, thereby increasing crop yield and farmland efficiency.

[0040] This embodiment provides a soil improvement and remediation device, such as... Figure 1 and 2 As shown, the device includes a frame 1, a plow 2 and a tillage repair mechanism 3 mounted on the frame 1. The plow 2 is fixedly installed in the middle of the frame 1 and has furrows capable of turning the soil to the left and right. In this embodiment, the structure of the plow 2 is as follows: Figure 3 As shown in the diagram, the arrows indicate the direction of soil tillage. The tillage and repair mechanisms 3 are symmetrically arranged on the left and right sides of the plow 2, with the plow 2 positioned forward between adjacent tillage and repair mechanisms 3. In practical applications, the frame 1 is mounted on agricultural machinery, driving the machinery through the field. This allows the plow 2 and the tillage and repair mechanisms 3 on both sides to work simultaneously on the field. The ridges on both sides of the plow 2 turn the soil on the ridges to both sides, while the tillage and repair mechanisms 3 not only repair the soil on the ridges but also simultaneously till the soil in the furrows, ensuring that the soil conditioner is fully and evenly distributed.

[0041] Specifically, in this embodiment, the tillage and restoration mechanism 3 includes a support frame 4, a distribution hopper 6, a lifting belt 51, a spraying assembly 7, and a screw conveyor assembly 8, etc.; Figure 6 As shown, the screw conveyor assembly 8 includes a mixing cylinder 82, a discharge chamber 86, a mixing motor 84, an auger, and a discharge plate 85. The support frame 4 is symmetrically mounted on the frame 1. The mixing cylinder 82 is fixedly mounted longitudinally at the bottom of the support frame 4 by angle steel. The front end of the mixing cylinder 82 is provided with a feed inlet 81, and the rear end of the mixing cylinder 82 is provided with a discharge outlet 83. An auger is installed inside the mixing cylinder 82. A drive motor is fixedly mounted on the rear end of the mixing cylinder 82. The drive motor is connected to the rotating shaft 93 inside the auger. The discharge chamber 86 is fixedly mounted above the mixing cylinder 82 and communicates with it.

[0042] Specifically, such as Figure 4 and Figure 6 As shown, in this embodiment, an arc-shaped shovel plate is welded and fixed to the front end of the mixing cylinder 82. The arc-shaped shovel plate is connected to the inlet of the mixing cylinder 82 to form a feed port 81. As the vehicle frame 1 moves forward, the soil in the furrow can be shoveled into the inlet of the mixing cylinder 82 by the arc-shaped shovel plate, and then transported backward by the auger inside the mixing cylinder 82. In this embodiment, the discharge port 83 of the mixing cylinder 82 faces the plow 2. Therefore, the soil mixed by the mixing cylinder 82 is discharged from the discharge port 83 to the inner side of the furrow, which facilitates the subsequent ridging operation.

[0043] like Figure 4As shown, a square-opening discharge chamber 86 is fixedly installed on the top of the mixing cylinder 82. A distribution hopper 6 is installed on the support frame 4 above the discharge chamber 86. A discharge plate 85 is fixedly disposed between the discharge chamber 86 and the distribution hopper 6. The inner end of the discharge plate 85 is fixed on the support frame 4, and its outer end extends downward at an incline into the discharge chamber 86. In this embodiment, the discharge plate 85 is used to receive the soil discharged from the bottom of the distribution hopper 6 and cooperates with the spraying assembly 7 to realize the spraying and remediation of the soil discharged from the distribution hopper 6.

[0044] In its specific structure, the material distribution hopper 6 of this embodiment includes a material distribution hopper cavity 61, a vibration motor 62, an arc plate 63, a spring seat 64, and a top frame 65, etc. The material distribution hopper cavity 61 has evenly spaced material distribution holes 66 inside, and arc plates 63 are fixedly welded to its front and rear edges to prevent soil in the material distribution hopper cavity 61 from shaking out from the front and rear sides during vibration, thus achieving soil aggregation within the cavity and ensuring the stability and safety of the material distribution hopper 6. Figure 4 As shown, a vibration motor 62 is fixedly installed inside the material distribution hopper 61, and its top and bottom are respectively fixedly connected to the support frame 4 through spring seats 64, as shown. Figure 5 As shown, taking the bottom installation position as an example, in this embodiment, the spring seat 64 includes a top seat 641, a vibration spring 643, and a base 642. The base 642 is fixed to the support frame 4, the top seat 641 is fixedly installed on the side wall of the arc plate 63, and a diagonal brace is provided on the top surface of the top seat 641. The vibration spring 643 is fixedly installed between the base 642 and the top seat 641. A top frame 65 is provided at the top of the material distribution hopper cavity 61, and a spring seat 64 is provided below the top frame 65. The base 642 of the spring seat 64 is fixedly installed on the spray frame 71.

[0045] In this embodiment, the distribution hopper 6 is configured such that when soil enters the hopper 6, the vibration motor 62 is activated, which can fully vibrate and shake the soil in the distribution hopper cavity 61 to disperse it, thereby breaking the cohesion between soil particles and making them easier to disperse, less prone to clumping, and effectively promoting soil flow. The fully vibrated soil falls onto the inclined discharge plate 85 through the distribution holes 66 at the bottom. The arrangement of the distribution holes 66 allows the soil to fall evenly and orderly onto the discharge plate 85, significantly reducing the problems of soil accumulation and blockage. At the same time, it helps to achieve uniform coverage and penetration during pesticide spraying, resulting in better treatment effects. It also helps to achieve uniform mixing of soil in the mixing cylinder 82, avoiding soil agglomeration and stratification, and ensuring soil quality.

[0046] like Figure 7As shown, the spray assembly 7 is arranged on the rear side of the distribution hopper 6. In this embodiment, the spray assembly 7 includes a spray frame 71, a medicine tank 72, a water pump 73, several nozzles 74, and a water pipe 75. The outer side of the spray frame 71 is fixed on the support frame 4. The medicine tank 72, the water pump 73, and the nozzles 74 are all arranged on the spray frame 71. Several nozzles 74 are fixedly installed on the inner end of the spray frame 71, and the nozzles 74 face the discharge plate 85. One end of the water pump 73 is connected to the medicine tank 72 on the spray frame 71, and the other end is connected to each nozzle 74 through the water pipe 75. Thus, each nozzle 74 can spray medicine onto the soil falling from the outlet of the distribution hopper 6 onto the discharge plate 85. The soil after spraying slides down into the mixing cylinder 82.

[0047] like Figure 2 and Figure 4 As shown, a lifting assembly 5 is also provided between the plow 2 and the hopper 6. The far end of the lifting assembly 5 is connected to the inner inlet of the hopper 6. When the plow 2 is tilling on the ridge, the lifting assembly 5 can transport the soil allocated to both sides into the hopper 6 respectively. In the specific structure, the lifting assembly 5 provided in this embodiment includes a lifting belt 51, a lifting frame 53, and a lifting motor 54. The lifting frame 53 is fixed vertically to the inner bottom of the support frame 4 in the transverse direction. A vertical frame is fixed to the outer end of the lifting frame 53 in the axial direction. The top and bottom of the lifting belt 51 are respectively connected to the vertical frame and the inner end of the lifting frame 53 through a rotating shaft 93. A lifting motor 54 is also fixed on one side wall of the lifting frame 53. The output shaft of the lifting motor 54 is connected to the rotating shaft 93 at the bottom of the lifting belt 51, thereby driving the lifting motor 54 to work and drive the movement of the lifting belt 51. Furthermore, protrusions 52 are evenly provided on the lifting belt 51 to reduce the probability of soil sliding down the lifting belt 51.

[0048] Working principle description: In actual application, the soil improvement and remediation device provided in this embodiment is mounted on the agricultural machinery equipment. The positions of the plow 2 and the support frame 4 are adjusted according to the distance between the ridge and the furrow, so that the plow 2 is placed in the middle of the ridge, and the feed inlets 81 of the mixing cylinders 82 on both sides correspond to the furrow. The agricultural machinery equipment is driven to move forward along the ridge, and the lifting motor 54 and the vibration motor 62 are started simultaneously. The plow 2 first performs a tillage operation on the ridge, and its plow clods can turn the soil on the ridge to both sides, preparing for subsequent soil remediation and tillage treatment. At the same time, the lifting belt 51 moves under the drive of the lifting motor 54, and transports the soil distributed to both sides of the ridge to the distribution hopper 6.

[0049] See Figure 8In the direction of the arrow, the soil in the distribution hopper 6 is fully vibrated and shaken and dispersed under the action of the vibration motor 62, which breaks the cohesion between soil particles. After vibration, the soil is more easily dispersed from the distribution hole 66 at the bottom of the distribution hopper cavity 61 and falls evenly onto the inclined discharge plate 85. The water pump 73 is started to spray the medicine from each nozzle 74, thereby spraying the soil falling from the outlet of the distribution hopper 6 onto the discharge plate 85. The sprayed soil slides down the discharge plate 85 into the mixing cylinder 82.

[0050] During the process of transporting soil from the raised beds via the lifting belt 51, the soil in the furrows is scooped up by the arc-shaped shovel at the front end of the mixing cylinder 82 and brought to the inlet of the mixing cylinder 82. Then, under the action of the auger inside the mixing cylinder 82, the soil is transported backward, thus mixing the soil in the raised beds with the soil in the furrows within the mixing cylinder 82. The auger inside the mixing cylinder 82 rotates under the drive of the mixing motor 84, transporting the soil backward. During the transport process, the soil and the soil amendment are fully mixed, achieving a uniform distribution of the soil amendment. Finally, the soil mixed by the mixing cylinder 82 is discharged from the outlet 83 to the inside of the furrows, where it mixes with the original soil in the furrows. In this way, the soil of the entire farmland is tilled and repaired, and the soil amendment is fully and evenly distributed, providing a good soil environment for crop growth.

[0051] After the soil conditioner has been sprayed on the ridged land, a ridging machine can be used to plow the land separately, turning the ridges over and mixing them with the original furrows. This ensures that the conditioner is evenly distributed in the soil, while simultaneously turning the original ridges into furrows and the furrows back into new ridges. This process not only repairs and improves the soil but also makes the newly ridged land more nutritious and fertile, thereby increasing crop yield and quality.

[0052] In practical applications, several nozzles can also be installed on the inner wall of the front side of the discharge chamber 86 above the mixing cylinder 82. Each nozzle is connected to the medicine tank 72 on the spray frame 71 via a water pipe, and the nozzles are oriented towards the inside of the mixing cylinder 82. This allows the soil in the furrows to be sprayed with pesticide when it is transported to the discharge chamber 86, thus providing targeted repair and improvement for both the ridges and furrows. It is important to note that when selecting a soil conditioner, significant differences in soil properties between the ridges and furrows must be considered. If the soil properties are similar, using the same conditioner is usually feasible. However, if differences exist, such as drier ridge soil and wetter furrow soil, conditioners with different functions may be needed to meet the needs of both. The formulation of the conditioner is existing technology and will not be elaborated upon here. The soil improvement and remediation device provided in this embodiment enables simultaneous tillage, repair, and improvement of farmland soil, improving soil quality and fertility, and contributing to crop growth and yield increases.

[0053] In Example 2, based on Example 1, as the workload increases, the amount of soil transported by the lifting belt 51 to the distribution hopper 6 also increases. However, the amount of soil falling from the bottom distribution hole 66 of the distribution hopper cavity 61 to the mixing cylinder 82 is fixed. Therefore, soil accumulation may occur in the distribution hopper 6. At the same time, there may be large clods of soil in the farmland, which can easily cause blockage of the distribution hole 66 in the hopper, thereby affecting the feeding rate and the quality of pesticide spraying. To solve the above problems, this example installs a screen plate 10 on the distribution hopper 6 and a dispersing component 9 above the lifting belt 51.

[0054] like Figure 9-11 As shown, in the specific implementation structure, the arc plate 63 on the rear side of the distribution hopper cavity 61 is higher than the front side, thus forming an inclined plane at the top of the arc plates 63 on both sides. A screening plate 10 is fixedly installed on the top of the arc plates 63 on both sides. The screening plate 10 is connected to the end of the lifting belt 51, and the front side of the screening plate 10 extends forward to the outside of the distribution hopper 6. The screening plate 10 has an inclined and arc-shaped bent structure, with screening holes evenly distributed on the plate. This allows the soil on the lifting belt 51 to be directly transported to the screening plate 10. Under the action of the vibrating motor 62, the soil is vibrated and screened on the screening plate 10. Some larger and harder soil clods, unable to pass through the screening holes, fall directly to the ground along the inclined structure of the screening plate 10, while looser soil passes through the screening holes and falls into the distribution hopper cavity 61. In this way, through a single vibration screening, preliminary treatment and classification of the soil are achieved, facilitating the spraying of pesticides.

[0055] In addition, to further improve the soil treatment efficiency and remediation quality, this embodiment also provides a dispersing component 9 above the lifting belt 51 to pre-disperse the softer soil clods on the lifting belt 51. The dispersing component 9 includes a frame 91, a drive wheel 92, a roller 94, a belt 96, and a driven wheel 97. The drive wheel 92 is fixedly mounted on the output shaft of the lifting motor 54. A frame 91 is axially fixed at the front end of the lifting frame 53, and adjacent frames 91 are connected to each other. A rotating shaft 93 is mounted on the upper part of the roller 94, which is fixedly mounted on the rotating shaft 93. One end of the rotating shaft 93 extends out of the upright frame 91 and is fixedly mounted on the driven wheel 97. The driving wheel 92 and the driven wheel 97 are driven by a belt 96. The roller 94 is also evenly distributed with teeth 95. When the driving motor 54 is working, the belt 96 can drive the roller 94 to rotate synchronously, thereby using the teeth 95 on the roller 94 to break up the soil on the lifting belt 51.

[0056] This embodiment further improves the processing efficiency and improvement quality of the soil improvement and remediation device by adding a sieve plate 10 and a dispersing component 9. The sieve plate 10 realizes the preliminary treatment and classification of the soil, avoiding the blockage of the distributing hole 66 by larger soil clods; while the dispersing component 9 further disperses the soil, making the soil looser and easier to mix and react with the chemical solution.

[0057] Example 3 describes the fastening method between the plow 2 and the frame 1.

[0058] like Figure 12 As shown, this embodiment provides a locking assembly for fastening and disassembling the plow 2 and the frame 1. Specifically, the locking assembly includes a connecting seat 11, a limiting seat 12, a locking seat 13, and a connecting plate 14. The connecting seat 11 is fixedly welded to the front side of the plow 2. In this embodiment, the connecting seat 11 has an L-shaped structure, with a base plate fixedly installed on its front side. Bolts are provided around the base plate. The locking seat 13 is located on the top of the frame 1 and is connected to the connecting seat 11 by bolts, thereby locking the plow 2 onto the frame 1. Connecting plates 14 are provided on both sides of the locking seat 13. A limiting seat 12 is fixed to the side of the connecting plate 14 away from the other side. The limiting seat 12 is fixed to the frame 1 by bolts. The tops of adjacent connecting plates 14 are fixed with bolts, thereby locking the plow 2 and the connecting seat 11 between adjacent limiting seats 12, preventing the plow 2 from shifting during operation. The plow 2 can also be removed from the frame 1 by tightening the bolts, making it convenient to use.

[0059] Example 4, based on Examples 1-3 above, provides a soil improvement and remediation method, using the soil improvement and remediation device described in Examples 1-3 above, specifically including the following steps:

[0060] Step 1: Connect the plow 2 and the tillage repair mechanism 3 of the device to the frame 1 through locking components and load them onto the agricultural machinery; then adjust the position of the plow 2 and the support frame 4 according to the distance between the ridge and the furrow, so that the plow 2 is placed in the middle of the ridge and the feed inlets 81 of the mixing cylinders 82 on both sides correspond to the furrows, and then tighten the plow 2 and the tillage repair mechanism 3 to the frame 1 respectively.

[0061] Step 2: Drive the agricultural machinery along the ridges, and simultaneously start the lifting motor 54 and the vibration motor 62. The plow 2 first turns over the ridges, and its plow blades turn the soil on the ridges to both sides. The lifting belt 51 transports the soil distributed to both sides of the ridges to the distribution hopper 6. At the same time, the soil in the furrows is scooped up by the arc-shaped shovel at the front end of the mixing cylinder 82 and put into the mixing cylinder 82.

[0062] Step 3: As the lifting belt 51 works, it synchronously drives the roller 94 to rotate, thereby breaking up the soil on the lifting belt 51 through the dispersing teeth 95 on the roller 94.

[0063] Step 4: Start the water pump 73 to spray the medicine from the nozzle 74 of the spray assembly 7, spray the soil falling from the outlet of the distribution hopper 6 onto the discharge plate 85, and the sprayed soil slides down the discharge plate 85 into the mixing cylinder 82, where it is mixed with the furrow soil under the action of the auger.

[0064] Step 5: The soil mixed by the mixing cylinder 82 is discharged from the discharge port 83 to the inside of the furrow, where it is mixed with the original soil in the furrow.

[0065] Step 6: After completing the soil improvement and restoration of the farmland, remove the tillage and restoration mechanism 3 from the agricultural machinery and let the agricultural machinery drive the plow 2 to carry out the plowing operation alone. Turn the ridges outward and mix them with the original furrows, so that the soil conditioner is fully and evenly distributed. After plowing, the original ridges become furrows, and the original furrows are re-ridged to become new ridges, which is convenient for the planting of a new round of crops.

[0066] The soil improvement and remediation method provided in this embodiment can achieve simultaneous tillage, remediation, and improvement of farmland soil, thereby improving soil quality and fertility, providing a good soil environment for crop growth, and thus increasing crop yield and quality.

[0067] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention is that, through this device, soil remediation operations can be directly performed on ridged farmland after crop harvesting, and the soil of both the ridges and furrows is remediated and improved separately. Then, the soil sprayed with the soil conditioner is mixed, causing the ridges to be turned over and mixed with the original furrows. After plowing the land with a ridging machine, the original ridges become furrows, and the original furrows are re-riveted to become new ridges. This not only completes the soil remediation and improvement but also makes the newly ridged field more nutrient-rich and fertile. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
