[0025] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 and Figure 2 A soil remediation cover film laying device, the soil remediation cover film laying device comprising:

[0028] Support component 1 includes a bracket 2 and a support shaft 3. Both ends of the support shaft 3 are rotatably connected to the bracket 2, and a membrane 4 is sleeved on the support shaft 3.

[0029] The pressure-fixing assembly 5 includes two first connecting rods 6, pressure rollers 7, and extrusion wheels 8. The two first connecting rods 6 are symmetrically connected to both sides of the support 2. The two ends of the pressure rollers 7 are rotatably connected to the two first connecting rods 6 respectively. The two extrusion wheels 8 are respectively sleeved on both sides of the pressure rollers 7.

[0030] The power assembly 9 is connected to the support shaft 3 and provides a power source for the support shaft 3.

[0031] Specifically, the power unit 9 provides power to the support shaft 3, causing the support shaft 3 to rotate on the bracket 2, which in turn drives the membrane 4, which is sleeved on the support shaft 3, to unfold. Two first connecting rods 6 symmetrically arranged on both sides of the bracket 2 support the pressure roller 7. The extrusion rollers 8 sleeved on both sides of the pressure roller 7 rotate with the pressure roller 7. When the device moves forward, the extrusion rollers 8 press the sides of the membrane 4 into the soil, achieving initial fixation of the membrane 4. At the same time, the pressure roller 7 extrudes the membrane 4 to make it fit tightly with the soil. This device integrates the functions of supporting, laying, and pressing the membrane 4, realizing the mechanization of soil remediation cover membrane laying and greatly improving laying efficiency.

[0032] The soil remediation cover film laying device of the above embodiment stably supports the membrane body 4 through the bracket 2 and support shaft 3 of the support component 1, providing basic support for the laying operation; the power component 9 provides power to the support shaft 3 to realize the automatic laying of the membrane body 4; the pressure roller 7 of the pressing component 5 cooperates with the extrusion wheel 8 to make the membrane body 4 penetrate into the soil on both sides and fit tightly with the soil, without the need for manual operation; compared with the traditional method of manually pressing soil to fix the cover film, it greatly improves the work efficiency, effectively solves the problem of low efficiency of the existing cover film fixing method, which consumes a lot of manpower and time costs and slows down the remediation progress in large-area soil remediation projects, and meets the needs of modern efficient and large-scale soil remediation operations.

[0033] As an feasible approach, refer to Figure 1 and Figure 2 The support assembly 1 also includes a combination roller 10, which is connected to the bracket 2 and is located between the support shaft 3 and the pressure roller 7.

[0034] Specifically, when the support shaft 3 rotates under the drive of the power component 9 to release the membrane 4, the membrane 4 will come into contact with the combined roller 10 during the unfolding process. The combined roller 10 maintains stability due to its connection structure with the support 2, and uses its own rotational characteristics to provide a support point for the membrane 4, guiding the membrane 4 to move smoothly from the support shaft 3 towards the pressure roller 7 at a suitable angle and tension. The combined roller 10 can effectively prevent the membrane 4 from shifting or wrinkling during the transmission process, ensuring that the membrane 4 is in good condition when entering between the pressure roller 7 and the extrusion roller 8, improving the quality of the cover film laying, reducing uneven laying and membrane 4 damage caused by membrane 4 transmission problems, and avoiding the time waste caused by frequent adjustments to the membrane 4.

[0035] As an feasible approach, refer to Figures 1 to 3 The compaction assembly 5 also includes a soil covering component 11, which includes a second connecting rod 12 and a flow guide shell 13. One end of the second connecting rod 12 is rotatably connected to the first connecting rod 6, and the other end of the second connecting rod 12 extends to the side of the pressure roller 7 facing away from the support 2 and is connected to the flow guide shell 13. The flow guide direction of the flow guide shell 13 is consistent with the movement trajectory direction of the extrusion wheel 8.

[0036] Specifically, during device operation, the first connecting rod 6 drives the second connecting rod 12 and the guide shell 13 to move accordingly. Since the guiding direction of the guide shell 13 is consistent with the movement trajectory of the extrusion wheel 8, after the extrusion wheel 8 presses the membrane 4 into the soil on both sides, the guide shell 13 guides the soil onto the membrane 4 processed by the extrusion wheel 8 as the device moves forward, thereby achieving automatic soil covering and fixing of the cover membrane without the need for manual soil covering. This effectively avoids the cover membrane from shifting, lifting, or being damaged due to external forces such as wind and rain erosion, ensuring the stability of the cover membrane during soil remediation and thus improving the effect and quality of soil remediation.

[0037] As an feasible approach, refer to Figure 4 and Figure 5 The pressure-fixing assembly 5 also includes a first adjustment component 14, which includes a positioning component 15, a mounting plate 16, a positioning rod 17, and a spring 18. One end of the positioning component 15 has several positioning holes 31, and the other end of the positioning component 15 passes through the second connecting rod 12 and is connected to the guide shell 13. One end of the mounting plate 16 is connected to the second connecting rod 12, and the other end of the mounting plate 16 has a connecting hole. The positioning rod 17 is connected to the mounting plate 16 through the spring 18, and one end of the positioning rod 17 passes through the connecting hole and the corresponding positioning hole 31.

[0038] Specifically, when the angle of the guide shell 13 needs to be adjusted, the positioning rod 17 is pulled out of the current positioning hole 31 using external force. At this time, the guide shell 13 can be rotated to drive the positioning component 15 to rotate around the second connecting rod 12. After adjusting to the appropriate angle, the positioning rod 17 is released. Under the elastic action of the spring 18, one end of the positioning rod 17 passes through the connecting hole of the mounting plate 16 and is inserted into the corresponding positioning hole 31, thereby fixing the angle of the guide shell 13. Through a simple structure, the angle of the guide shell 13 can be flexibly adjusted. The position of the guide shell 13 can be precisely adjusted according to different terrain conditions, soil conditions, and cover film laying requirements, ensuring that the soil can be accurately covered on the membrane 4, improving the accuracy and uniformity of soil covering, thereby enhancing the fixing effect of the cover film, ensuring the smooth progress of soil remediation work, and improving the applicability and practicality of the entire laying device.

[0039] As an feasible approach, refer to Figure 4 and Figure 5 The clamping assembly 5 also includes a second adjusting component 19, which includes a first connecting block 20 and a first screw 21. The first connecting block 20 is rotatably connected to the first connecting rod 6, and the first screw 21 is threadedly connected to the first connecting block 20. One end of the first screw 21 passes through the first connecting block 20 and is rotatably hinged to the second connecting rod 12.

[0040] Specifically, by rotating the first screw 21, its threaded engagement with the first connecting block 20 allows the first screw 21 to move axially within the first connecting block 20. Since one end of the first screw 21 is rotatably hinged to the second connecting rod 12, and the first connecting block 20 is rotatably connected to the first connecting rod 6, the movement of the first screw 21 causes the second connecting rod 12 to rotate around its connection point with the first connecting rod 6. This adjusts the position and angle of the second connecting rod 12, ultimately changing the position and angle of the guide shell 13 connected to the second connecting rod 12. This allows for more precise and flexible adjustment of the position and angle of the guide shell 13, adapting to the complex needs of different terrains and soil remediation cover membrane installation, further enhancing the adaptability and stability of the device, and improving the accuracy and effectiveness of soil covering.

[0041] As an feasible approach, refer to Figures 1 to 3 The clamping assembly 5 also includes a third adjusting component 22, which includes a second connecting block 23 and an electric push rod 24. The fixed end of the electric push rod 24 is hinged to the bracket 2, and the movable end of the electric push rod 24 is connected to the second connecting block 23. The second connecting block 23 is rotatably connected to the first connecting rod 6.

[0042] Specifically, after the electric push rod 24 is powered on, its movable end will extend or shorten according to control commands. Since the fixed end of the electric push rod 24 is hinged to the bracket 2, and the movable end is connected to the second connecting block 23, and the second connecting block 23 is rotatably connected to the first connecting rod 6, the extension and retraction of the movable end of the electric push rod 24 will drive the second connecting block 23 to move, thereby causing the first connecting rod 6 to rotate around the connection point with the bracket 2. This rotation will change the position and angle of the entire compaction assembly 5, thereby adjusting the working posture of the pressure roller 7, the extrusion wheel 8, and other components connected to the first connecting rod 6 (such as the guide shell 13). This enables rapid and precise adjustment of the compaction assembly 5, allowing for quick adjustment of the angle and position of the compaction assembly 5 according to different soil conditions, terrain conditions, and cover film laying requirements. This ensures better contact between the pressure roller 7 and the extrusion wheel 8 and the ground, resulting in better laying and fixing of the membrane 4, ensuring that the cover film adheres tightly to the soil, and improving the overall performance of the cover film laying device for soil remediation.

[0043] As an feasible approach, refer to Figure 3 Each extrusion roller 8 has a fixing component 25 connected to one side. The fixing component 25 includes a connecting sleeve 26 and a second screw 27. The connecting sleeve 26 is rotatably connected to one side of the extrusion roller 8 and is sleeved on the pressure roller 7. The second screw 27 is threadedly connected to the connecting sleeve 26, and one end of the second screw 27 passes through the connecting sleeve 26 and abuts against the pressure roller 7.

[0044] Specifically, by rotating the second screw 27, its threaded engagement with the connecting sleeve 26 allows the second screw 27 to move axially within the connecting sleeve 26. Since one end of the second screw 27 abuts against the pressure roller 7, its movement generates pressure on the pressure roller 7, thereby firmly fixing the connecting sleeve 26 and the extrusion roller 8 rotatably connected to the connecting sleeve 26 onto the pressure roller 7. This simple threaded structure allows for convenient and quick adjustment of the distance between the two extrusion rollers 8. In actual soil remediation cover film laying operations, different film thicknesses, soil textures, and laying requirements may necessitate adjustments to the spacing of the extrusion rollers 8. This fixing component 25 meets these diverse needs, ensuring that the extrusion rollers 8 apply appropriate pressure to both sides of the film 4 according to actual conditions, allowing the film 4 to better embed itself into the soil.

[0045] As an feasible approach, refer to Figure 1 and Figure 2 The power assembly 9 includes a first gear 28, a second gear 29 and a motor 30. The first gear 28 is connected to one end of the support shaft 3, the motor 30 is connected to the bracket 2, and the output shaft of the motor 30 is connected to the second gear 29. The second gear 29 meshes with the first gear 28.

[0046] Specifically, after the motor 30 is powered on and started, its output shaft drives the second gear 29 to rotate. Since the second gear 29 meshes with the first gear 28, the rotation of the second gear 29 drives the first gear 28 to rotate synchronously. The first gear 28 is connected to one end of the support shaft 3, thereby driving the support shaft 3 to rotate on the bracket 2, realizing the automatic unfolding of the membrane 4. The gear transmission provides stable and reliable power to the support shaft 3, greatly improving work efficiency and reducing labor costs compared to manual membrane laying. At the same time, the speed of the motor 30 is controllable, allowing adjustment of the rotation speed of the support shaft 3 according to actual laying requirements, making the laying speed of the membrane 4 more uniform and stable.

[0047] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
