Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil pollution remediation technology, and in particular to a soil pollution remediation device for ecological environment restoration. Background Technology
[0002] Soil, as the fundamental carrier of the ecosystem, poses a serious threat to agricultural production, groundwater safety, and ecological balance due to its pollution. Among current soil pollution remediation technologies, chemical remediation has become the mainstream method due to its rapid effectiveness and wide applicability. Its core lies in applying the remediation solution evenly to the polluted soil to degrade or immobilize pollutants.
[0003] However, existing remediation equipment has significant technical bottlenecks: most equipment only applies remediation solution through surface spraying or shallow injection, making it difficult for the liquid to penetrate the soil surface structure and reach the internal pores, resulting in insufficient contact between the agent and pollutants; at the same time, the remediation solution exposed to air is prone to rapid evaporation due to factors such as high temperature and light, further reducing the effective utilization rate. Practice has shown that in order to achieve the ideal remediation effect, an excessive amount of remediation solution needs to be sprayed to compensate for insufficient penetration, resulting in waste of agents and the risk of secondary soil pollution.
[0004] Furthermore, we disclose a soil pollution remediation device for ecological environment restoration to meet the practical needs of existing technologies where remediation solutions are difficult to penetrate into the soil, resulting in poor remediation effects. Utility Model Content
[0005] In view of this, the purpose of this utility model is to propose a soil pollution treatment device for ecological environment restoration, so as to solve the problem that the remediation solution is difficult to penetrate into the soil, resulting in poor remediation effect in the prior art.
[0006] To achieve the above objectives, this utility model provides a soil pollution remediation device for ecological environment restoration, comprising a handcart. First support seats are fixedly connected to both sides of the lower end face of the handcart. Baffles are fixedly connected to the lower ends of the two first support seats on their adjacent sides. One side of each baffle is arc-shaped and extends outwards from the handcart. A second support seat is fixedly connected to one side of the lower end face of the handcart. A soil-turning component is provided on the second support seat for loosening the soil. A crushing component is provided between the two baffles for breaking up large clods of soil into smaller clods. A spraying component is provided on one side of the middle of the handcart for spraying remediation fluid onto the soil.
[0007] Preferably, the soil turning assembly includes two third support seats fixedly connected to one side of the middle of the lower end face of the handcart. Each of the two third support seats is rotatably connected to a connecting rod. The ends of the two connecting rods away from the third support seats are evenly spaced and fixedly connected to a plurality of insert rods. A servo motor is provided on one side of the upper middle of the second support seat. The output end of the servo motor is fixedly connected to a connecting plate. The upper end of the connecting plate is engaged and rotatably connected to a retaining shaft. A waist-shaped groove is opened in the middle of one of the connecting rods. The middle of the retaining shaft is slidably connected in the waist-shaped groove.
[0008] Preferably, the crushing assembly includes an extrusion plate disposed on one side between two baffles. The extrusion plate is arc-shaped. Multiple breaking plates are fixedly connected at even intervals to the lower end of the extrusion plate. Multiple protrusions are fixedly connected at even intervals to the lower end face of the extrusion plate between the breaking plates. A pressing seat is fixedly connected to the middle of the upper end of the extrusion plate. The upper end of the pressing seat is located at the lower end of the connecting rod near the third support seat.
[0009] Preferably, a groove is provided in the middle of both baffles, and sliding plates are fixedly connected to both sides of the middle of the extrusion plate. The two sliding plates are slidably connected in the two grooves respectively. A fixing plate is fixedly connected to the middle of the outer wall of the baffle, and a telescopic spring is fixedly connected to the lower end of the fixing plate. The lower end of the telescopic spring is fixedly connected to the sliding plate.
[0010] Preferably, a plurality of crushing rollers are engaged and rotatably connected between the two baffles on the side away from the extrusion plate.
[0011] Preferably, the spraying assembly includes a liquid storage tank fixedly connected to the middle of the upper end face of the handcart, an infusion pipe fixedly connected to the lower end of the middle of one side end face of the liquid storage tank, a delivery pump provided on the infusion pipe on one side of the liquid storage tank, the lower end of the infusion pipe passing through the handcart and fixedly connected to a diversion pipe, and a plurality of atomizing nozzles fixedly connected at even intervals at the lower end of the diversion pipe.
[0012] Preferably, a push rod is fixedly connected to one side of the handcart, and a lever is fixedly connected to the lower middle part of the push rod. The lower end of the lever is arc-shaped, and the lever is used to cover the soil that has been turned up.
[0013] The beneficial effects of this utility model are:
[0014] 1. This soil pollution remediation device for ecological environment restoration addresses the shortcomings of traditional remediation equipment, which can only achieve surface spraying. This soil turning component uses mechanical power to achieve deep soil loosening. Its unique reciprocating motion trajectory can generate three-dimensional spatial disturbance, forming a loose layer of a certain height in the vertical direction. This allows the remediation liquid to penetrate into the deep soil layer along the loosened pores when sprayed. Compared with surface spraying, this structure significantly improves the utilization rate of the remediation liquid, while avoiding the loss of efficacy caused by the evaporation of the agent on the surface. The increased gaps between soil particles after loosening create ideal conditions for the subsequent full contact between the remediation liquid and pollutants, significantly improving the remediation efficiency per unit of agent.
[0015] 2. This soil pollution remediation device for ecological environment restoration features a crushing component that significantly improves soil remediation efficiency through a two-stage crushing mechanism. First, the wedge-shaped structure of the extrusion plate, breaking plate, and protrusions effectively breaks down large, loose soil clods from the soil turning component into fine particles, significantly increasing the soil's specific surface area and creating ideal pore channels for subsequent remediation fluid penetration. Second, the incompletely crushed soil clods are further ground by the crushing roller to form a uniform particle layer, avoiding excessive crushing that damages the soil structure while ensuring sufficient contact between the remediation fluid and pollutants. This design achieves continuous optimization of soil particle size distribution through mechanical linkage, enhancing the adsorption capacity of the remediation fluid while reducing ineffective evaporation, making the remediation process more efficient and environmentally friendly.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0027] like Figures 1 to 6 As shown, a soil pollution remediation device for ecological environment restoration includes a handcart 1. First support seats 8 are fixedly connected to both sides of the lower end face of the handcart 1. Baffles 7 are fixedly connected to the lower ends of the two first support seats 8 on their adjacent sides. One side of each baffle 7 is arc-shaped and expands outwards from the handcart 1. A second support seat 13 is fixedly connected to one side of the lower end face of the handcart 1. A soil-turning component is installed on the second support seat 13 to loosen the soil. A crushing component is installed between the two baffles 7 to break up large soil clods into smaller clods. A spraying component is installed on one side of the middle of the handcart 1 to spray remediation liquid onto the soil. A push rod 2 is fixedly connected to one side of the handcart 1. A lever 3 is fixedly connected to the lower end of the middle of the push rod 2. The lower end of the lever 3 is arc-shaped and is used to cover the turned-up soil.
[0028] During operation, the operator pushes the handcart 1 to the area to be repaired, starts the servo motor 19 to drive the soil turning component, and the connecting rod 11 swings back and forth under the drive of the motor, so that the insert rod 12 penetrates into the soil and is pulled backward and upward to loosen the surface compacted soil clods. When the loosened soil falls back naturally under the action of gravity, the extrusion plate 14 of the crushing component moves downward under the pressure of the connecting rod 11. The wedge structure of the breaking plate 22 and the protrusion 23 breaks the large soil clods into fine particles. The soil clods that are not completely crushed roll into the crushing roller 16 area for secondary grinding. At the same time, the delivery pump 6 of the spraying component pumps the repair liquid in the storage tank 4 to the diversion pipe 9, which is sprayed out through the evenly distributed atomizing nozzles 10 to form micron-level droplets covering the entire working surface, which fully contact the crushed soil. Finally, the push plate 3 moves with the push rod 2 to evenly cover the processed soil, completing a single repair cycle. When the handcart 1 continues to move forward, the components work together to achieve continuous repair operations.
[0029] Furthermore, such as Figures 1 to 4 As shown, the soil turning assembly includes two third support seats 18 fixedly connected to one side of the middle of the lower end face of the handcart 1. Each of the two third support seats 18 is rotatably connected to one side of a connecting rod 11. The ends of the two connecting rods 11 away from the third support seats 18 are evenly spaced and fixedly connected to multiple insert rods 12. A servo motor 19 is provided on one side of the middle of the upper end of the second support seat 13. A connecting plate 20 is fixedly connected to the output end of the servo motor 19. A retaining shaft 21 is rotatably connected to the upper end of the connecting plate 20. A waist-shaped groove 17 is opened in the middle of one side of the connecting rod 11. The middle of the retaining shaft 21 is slidably connected in the waist-shaped groove 17.
[0030] The soil-tillage assembly is driven by a servo motor 19 to achieve efficient soil loosening. Upon startup, the servo motor 19 drives the connecting plate 20 to rotate around its axis. The retaining shaft 21 at the end of the connecting plate 20 slides along the waist-shaped groove 17 in the middle of the connecting rod 11. The constraint of the waist-shaped groove 17 converts the rotational motion into the reciprocating swing of the connecting rod 11, allowing the evenly distributed inserts 12 to penetrate deep into the soil. When the connecting rod 11 swings to its lowest point, the tips of the inserts 12 reach their maximum penetration depth and are pulled upwards and backwards, using leverage to pry up compacted soil clods. When it swings to its highest point, the inserts 12 quickly return to their original position along their trajectory, and the loosened soil naturally falls back under gravity. This process, continuously operated by the motor, forms a periodic soil-tillage operation, effectively breaking down the hard crust structure of the soil surface and completing the soil loosening work.
[0031] Furthermore, such as Figures 1 to 6As shown, the crushing assembly includes an extrusion plate 14 disposed on one side between two baffles 7. The extrusion plate 14 is arc-shaped. Multiple breaking plates 22 are fixedly connected at even intervals at the lower end of the extrusion plate 14. Multiple protrusions 23 are fixedly connected at even intervals between the breaking plates 22 on the lower end face of the extrusion plate 14. A pressing seat 15 is fixedly connected to the middle of the upper end of the extrusion plate 14. The upper end of the pressing seat 15 is located at the lower end of the connecting rod 11 near the third support seat 18. A sliding groove 27 is opened in the middle of both baffles 7. Sliding plates 26 are fixedly connected to both sides of the middle of the extrusion plate 14. The two sliding plates 26 are slidably connected in the two sliding grooves 27 respectively. A fixing plate 24 is fixedly connected to the middle of the outer wall of the baffle 7. A telescopic spring 25 is fixedly connected to the lower end of the fixing plate 24. The lower end of the telescopic spring 25 is fixedly connected to the sliding plate 26. Multiple crushing rollers 16 are engaged and rotatably connected between the two baffles 7 on the side away from the extrusion plate 14.
[0032] The crushing assembly employs a working mechanism combining mechanical linkage and elastic reset. When the connecting rod 11 of the soil-turning assembly swings to its highest point under the drive of the servo motor 19, the end of the connecting rod 11 presses against the pressing seat 15. This pressing action is converted into the vertical downward movement of the extrusion plate 14 through the pressing seat 15. The breaking plate 22 and protrusions 23 at the lower end of the arc-shaped extrusion plate 14 act synchronously on the loosened soil. The breaking plate 22 adopts a wedge-shaped structure design, and its sharp edges can cut into the cracks in the soil clods, while the staggered arrangement of the protrusions 23 forms a shear force field, causing large soil clods to split under multi-directional stress during the extrusion process. When the connecting rod 11 swings to the lowest point and completes the pressing, the elastic potential energy of the telescopic spring 25 is released, pushing the sliding plate 26 to reset upward along the groove 27, and driving the extrusion plate 14 back to its original position to prepare for the next crushing action. The soil clods that are not completely crushed roll down to the crushing roller 16 area under the action of gravity, and the rolling pressure generated by the differential rotation of the multi-roller further refines the soil particles.
[0033] Furthermore, such as Figure 1 As shown, the spraying assembly includes a liquid storage tank 4 fixedly connected to the middle of the upper end face of the handcart 1. A delivery pipe 5 is fixedly connected to the lower end of the middle of one side end face of the liquid storage tank 4. A delivery pump 6 is provided on the delivery pipe 5 on one side of the liquid storage tank 4. The lower end of the delivery pipe 5 passes through the handcart 1 and is fixedly connected to a diversion pipe 9. Multiple atomizing nozzles 10 are fixedly connected at even intervals at the lower end of the diversion pipe 9.
[0034] The spraying assembly achieves efficient spraying of the repair liquid through pressure atomization technology. The repair liquid in the storage tank 4 is transported to the distribution pipe 9 through the delivery pipe 5 by the delivery pump 6. The distribution pipe 9 evenly distributes the repair liquid to each branch and finally sprays it out through the atomizing nozzle 10. The atomizing nozzle 10 adopts a special nozzle design and uses the principle of fluid dynamics to atomize the repair liquid into fine particles, expand the coverage area, and enable the repair liquid to act evenly on the soil surface and penetrate into the deep soil layer, thereby improving the repair effect.
