Description

[0032] 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.

[0033] Please see the appendix Figure 1 -Appendix Figure 11This invention provides a novel soil purification device for contaminated agricultural farmland, comprising two support frames 1, with multiple support rods 2 fixedly connected between the two support frames 1. The two ends of each support rod 2 penetrate the two support frames 1. A water tank 3 is fixedly connected to the outer surface of each support rod 2, located between the two support frames 1. A drive assembly 4 is disposed outside the support frames 1, and a conversion assembly 5 is disposed inside the drive assembly 4. A support plate 6 is fixedly connected to the output end of the conversion assembly 5. Two connecting pipes 7 are fixedly connected to the lower surface of the support plate 6. An atomizing plug 8 and a connecting pipe 9 are sequentially flanged below the connecting pipes 7. The internal sliding connection of the atomizing plug 8 is a sealing block 10, the lower surface of the sealing block 10 is fixedly connected to a telescopic rod 11, the sealing block 10 is fixedly connected to a squeezing block 12 through the telescopic rod 11, the outer surface of the atomizing plug 8 is provided with a plurality of atomizing holes 13 penetrating its outer surface, the outer surface of the connecting tube 2 9 is provided with two sliding grooves 14 penetrating its outer surface, the lower surface of the squeezing block 12 is fixedly connected to a trigger rod 15, the trigger rod 15 is slidably connected inside the sliding groove 14, the lower end of the connecting tube 2 9 is threaded with a spike 16, the upper surface of the water tank 3 is fixedly connected to a workbench 17, and the upper surface of the workbench 17 is provided with a preparation component 18.

[0034] Specifically, the support frame 1 and support rod 2 form the main frame to support the water tank 3 and the workbench 17. The drive component 4 converts the rotational power into the vertical movement of the support plate 6 through the conversion component 5. The support plate 6 forms a purification agent delivery channel through the first connecting pipe 7 and the second connecting pipe 9. The sealing block 10 set inside the atomizing plug 8 forms a linkage mechanism with the extrusion block 12 through the telescopic rod 11. When the spike 16 pierces the soil, the trigger rod 15 pushes the extrusion block 12 up along the sliding groove 14, causing the sealing block 10 to move down and release the sealing state of the atomizing hole 13. At this time, the purification agent processed by the preparation component 18 is delivered to the atomizing plug 8 through the second connecting pipe 9 and forms an atomized spray through the atomizing hole 13 to achieve deep soil purification. The workbench 17 provides an installation platform for the preparation component 18 to complete the purification agent preparation and delivery process. The entire system achieves the coordinated operation of precise injection and atomization control of the purification agent through mechanical linkage.

[0035] The drive assembly 4 includes two connecting plates 401, a drive shaft 402 is fixedly connected between the two connecting plates 401, a drive motor 403 is mounted on the outside of the drive shaft 402, a drive wheel 404 is rotatably connected to both ends of the drive shaft 402, a track 405 is engaged on the outer surface of the drive wheel 404, a stabilizing assembly 406 is provided inside the track 405, and a driven wheel 407 is rotatably connected to the output end of the stabilizing assembly 406.

[0036] Specifically, the drive assembly 4 constructs a power transmission frame through the connecting plate 401. The drive shaft 402 drives the drive wheel 404 to rotate under the drive motor 403. The meshing transmission between the drive wheel 404 and the track 405 forms a continuous power output. The stabilizing component 406 set inside the track 405 maintains the stability of the transmission system through dynamic adjustment. The driven wheel 407 receives the rotational power transmitted by the track 405 to achieve torque output. The entire system converts the motor power into linear drive through the synergistic effect of gear meshing and track 405 transmission. The intervention of the stabilizing component 406 effectively eliminates vibration offset during the transmission process, ensuring that the drive assembly 4 maintains stable power transmission efficiency during long-term operation.

[0037] The stabilizing component 406 includes a driven wheel 4061, which meshes with the track 405. A connecting frame 4062 is rotatably connected inside the driven wheel 4061. Two curved frames 4063 are rotatably connected between the two support rods 2. A stabilizing shaft 4064 is rotatably connected between the two curved frames 4063. One end of the connecting frame 4062 away from the driven wheel 4061 is rotatably connected to one end of the curved frame 4063. An auxiliary wheel 4065 is rotatably connected to the lower end of the side surface of the curved frame 4063. The auxiliary wheel 4065 meshes with the track 405. A spring 4066 is fixedly connected to the upper end of the two curved frames 4063.

[0038] Specifically, the stabilizing component 406 receives transmission power through the engagement of the driven wheel 4061 with the track 405. The connecting frame 4062 is connected to the curved frame 4063 to maintain the necessary length of the track 405. The curved frame 4063 maintains its own stability through the stabilizing shaft 4064. The auxiliary wheel 4065 at its lower end dynamically adjusts the contact angle with the track 405. The engagement of the auxiliary wheel 4065 maintains the tension balance of the track 405. The spring 4066 generates elastic deformation to absorb mechanical vibration when the curved frame 4063 moves. The entire mechanism achieves self-stabilization of the transmission system through dynamic adjustment. The lever structure of the curved frame 4063 and the elastic reset of the spring 4066 work together to effectively compensate for the length deformation of the track 405 during operation, ensuring that the drive component 4 maintains a constant transmission efficiency under different working conditions.

[0039] The conversion assembly 5 includes a rotating rod 501, which is rotatably connected inside the support frame 1. Both ends of the rotating rod 501 pass through the support frame 1 and are fixedly connected to two driven wheels 502. The driven wheels 502 mesh with the track 405. Inside the two support frames 1, a gear 503 is fixedly connected to the outer surface of the rotating rod 501. A gear 504 meshes directly below the gear 503. A fixing plate 505 is provided outside the gears 503 and 504. The gears 503 and 504 are rotatably connected to... Inside the fixed plate 505, two fixed rods 506 are fixedly connected between the two support frames 1. The fixed plate 505 is fixed between the two support frames 1 by the fixed rods 506. A conversion frame 507 is fixedly connected to the edges on both sides of the outer surface of the gear 2 504. A limit frame 508 is rotatably connected to the outer surface of the rotating rod 501. The limit frame 508 is located outside the fixed plate 505. The conversion frame 507 is slidably connected inside the limit frame 508. The lower end of the conversion frame 507 passes through the limit frame 508 and is fixedly connected to the upper surface of the support plate 6.

[0040] Specifically, the conversion component 5 receives the power of the track 405 transmitted by the driven wheel 3 502 through the rotating rod 501. The meshing of gear 1 503 and gear 2 504 converts the horizontal rotation into vertical motion. The fixed plate 505 provides stable support for the gear set to ensure transmission accuracy. The conversion frame 507 rotates with gear 2 504 and generates eccentric motion. The limit frame 508 constrains the motion trajectory of the conversion frame 507 to form a regular reciprocating motion. The support plate 6 achieves vertical lifting and lowering under the traction of the conversion frame 507. The entire mechanism, through the combination of gear transmission and crank-slider principle, converts the rotational power of the drive component 4 into precise downward pressure of the purification system. The guiding effect of the limit frame 508 effectively eliminates the radial offset during the movement of the conversion frame 507, ensuring that the support plate 6 maintains a straight motion trajectory.

[0041] The preparation component 18 consists of a crushing component 1801 and a mixing component 1802. The crushing component 1801 includes a crushing tank 18011, which is fixedly connected to one end of the upper surface of the workbench 17. A motor 18012 and a reducer 18013 are fixedly connected to the upper surface of the workbench 17. The output end of the motor 18012 is fixedly connected to the input end of the reducer 18013. A crushing blade 18014 is rotatably connected inside the crushing tank 18011. A bevel gear 18015 is fixedly connected to the input end of the crushing blade 18014. A bevel gear 2 18016 is fixedly connected to the output end of the reducer 18013. The bevel gear 18015 and the bevel gear 2 18016 mesh with each other.

[0042] Specifically, the crushing component 1801 of the preparation component 18 is driven by a motor 18012 to reduce the output torque of a reducer 18013. The meshing of bevel gear 18016 and bevel gear 18015 converts the horizontal rotation into vertical axial motion. The crushing blade 18014 achieves high-speed rotation under the transmission of bevel gears. The crushing tank 18011 provides a closed working space for soil crushing. The reducer 18013 ensures that the crushing blade 18014 has sufficient crushing strength through torque amplification. The structural design of the bevel gear set realizes the effective conversion of the power transmission direction. The entire crushing system converts the motor power into high-intensity shearing force through multi-stage transmission, realizing the uniform crushing treatment of contaminated soil and providing raw materials that meet the particle size requirements for subsequent mixing processes.

[0043] The mixing assembly 1802 includes a mixing tank 18021, which is fixedly connected to the other end of the upper surface of the workbench 17. A second motor 18022 and a second reducer 18023 are fixedly connected to the upper surface of the workbench 17. The output end of the second motor 18022 is fixedly connected to the input end of the second reducer 18023. An agitator 18024 is rotatably connected inside the mixing tank 18021. A third bevel gear 18025 is fixedly connected to the input end of the agitator 18024. A fourth bevel gear 18026 is fixedly connected to the output end of the second reducer 18023. The third bevel gear 18025 and the fourth bevel gear 18026 mesh with each other.

[0044] Specifically, the mixing component 1802 drives the reducer 18023 via the second motor 18022 to output the adjusted speed. The meshing of the fourth bevel gear 18026 and the third bevel gear 18025 converts the horizontal axial rotation into vertical power. The stirring paddle 18024 achieves three-dimensional stirring under the transmission of the bevel gears. The mixing tank 18021 provides a sealed space for the mixing reaction of the purifying agent and the soil. The second reducer 18023 optimizes the mixing efficiency of the stirring paddle 18024 by adjusting the speed. The power conversion structure of the bevel gear set ensures that the stirring paddle 18024 obtains sufficient torque output. The entire system achieves uniform mixing of materials through multi-stage transmission. The crushed soil and the purifying agent form full contact under the action of the stirring paddle 18024, providing a homogenized mixture for the subsequent atomization injection process.

[0045] A screw feeder 19 is fixedly connected between the output end of the crushing tank 18011 and the input end of the mixing tank 18021.

[0046] Specifically, the screw feeder 19 is used to transfer the material in the crushing tank 18011 to the mixing tank 18021.

[0047] A blower 20 and a water pump 21 are fixedly connected to the upper surface of the workbench 17. The input end of the blower 20 is connected to the outside, and the output end of the blower 20 is connected to the crushing tank 18011. The input end of the water pump 21 is connected to the water tank 3, and the output end of the water pump 21 is connected to the mixing tank 18021.

[0048] Specifically, the blower 20 provides airflow assistance to the crushing tank 18011 through external air input, accelerating the settling of dust and material flow during the crushing process. The water pump 21 transports the purified liquid in the water tank 3 to the mixing tank 18021 to participate in the mixing reaction. The directional transport of airflow and liquid forms a two-way supply for material processing. The airflow intervention of the blower 20 improves the crushing efficiency while preventing dust from overflowing. The liquid transport of the water pump 21 ensures the accurate proportion of the purifying agent. The two work together to build a material transport channel for the crushing-mixing process, providing the necessary media supply support for continuous production.

[0049] A flexible conveying pipe 22 is connected between the mixing tank 18021 and the connecting pipe 2 9. An electric valve 23 is installed inside the flexible conveying pipe 22. The connection between the flexible conveying pipe 22 and the connecting pipe 2 9 is located between the sealing block 10 and the extrusion block 12.

[0050] Specifically, the flexible conveying pipe 22 establishes a material transmission channel between the mixing tank 18021 and the connecting pipe 9. The electric valve 23 controls the start and stop of the conveying of the mixture and the flow rate adjustment. The connection point is set between the sealing block 10 and the extrusion block 12 to form a pressure buffer area. When the extrusion block 12 moves down, it releases space to accommodate the conveyed material. The flexible material adapts to the positional changes caused by the lifting and lowering of the support plate 6. The intelligent control of the electric valve 23 realizes the timing coordination of the delivery of the purifying agent and the atomization injection, ensuring that the mixed material arrives at the injection position synchronously when the atomization hole 13 is opened, forming a precise material supply-atomization injection linkage mechanism.

[0051] A second spring 24 is fixedly connected between the closing block 10 and the pressing block 12, and the second spring 24 surrounds the outside of the telescopic rod 11.

[0052] Specifically, spring 24 provides elastic restoring force between the sealing block 10 and the extrusion block 12. The structural design surrounding the telescopic rod 11 ensures linear guidance of the compression stroke. When the trigger rod 15 pushes the extrusion block 12 upward, spring 24 stores elastic potential energy. After the external force is released, it pushes the sealing block 10 to reset and seal the atomizing hole 13. The intervention of the elastic element realizes the automatic opening and closing control of the atomizing hole 13, ensuring that the purifier is sprayed only during the injection stage, avoiding material leakage when the equipment is idle. At the same time, the buffer mechanism reduces the wear of the sealing surface caused by mechanical impact.

[0053] Working Principle: During operation, this equipment first prepares the material. In this stage, solid lime is first placed into the crushing tank 18011. Then, motor 18012 is started, driving bevel gear 18016 to rotate via reducer 18013. Since bevel gear 18016 meshes with bevel gear 18015, bevel gear 18015 drives the crushing blades 18014 to pulverize the raw material in the crushing tank 18011. Simultaneously, fan 20 continuously supplies airflow into the crushing tank 18011. To prevent powder caking, the pulverized material is quantitatively conveyed to the mixing tank 18021 by the screw feeder 19 under the action of airflow. Then, the mixing component 1802 is started. First, the water pump 21 injects water from the water tank 3 into the mixing tank 18021. At the same time, the motor 18022 drives the bevel gear 18026 to rotate through the reducer 18023. Then, the bevel gear 18025 drives the agitator 18024 to stir the mixture in the mixing tank 18021, and finally a liquid lime slurry of suitable concentration and uniformity is formed.

[0054] After the liquid lime slurry is prepared, it enters the dispersing stage (slurry preparation can continue). The prepared slurry enters the closed space formed by connecting pipe 7, connecting pipe 9, sealing block 10, and extrusion block 12 through flexible conveying pipe 22. Then, the drive motor 403 of the drive assembly 4 is started, which drives the track 405 through the drive wheel 404. After the transmission path is stabilized by the auxiliary wheel 4065 of the stabilizing assembly 406, the track 405 drives the driven wheel 502 to rotate. Then, the gear 1 503 outside the rotating rod 501 drives the gear 2 504 to rotate. The rotation of gear 2 504 causes the conversion frame 507 on both sides to make eccentric movements. At the same time, under the restriction of the limit frame 508, the conversion frame 507 reciprocates linearly within a specified range, and finally realizes the rotation of the material. The motion is converted into the reciprocating vertical motion of the conversion frame 507; when the conversion frame 507 moves downward, it pushes the support plate 6 to drive the spike 16 to press down. When the spike 16 pierces the soil, the trigger rod 15 moves upward along the sliding groove 14 under the action of the soil. It lifts the sealing block 10 and compresses the spring 24 through the squeezing block 12 and the telescopic rod 11, so that the atomizing hole 13 blocked by the sealing block 10 is completely blocked. At this time, the liquid lime in the mixing tank 18021 enters the connecting pipe 9 through the flexible conveying pipe 22 and the electric valve 23. Under the squeezing of the squeezing block 12, it forms a fine mist droplet through the atomizing hole 13 and spreads to the surroundings. Then the conversion frame 507 moves upward, the squeezing block 12 and the sealing block 10 reset and seal the atomizing hole 13 to prevent soil backfilling and blockage. At the same time, the electric valve 23 is opened to re-inject the slurry, and the cycle continues.
