Description

Technical Field

[0001] The present invention relates to the field of land restoration, and particularly to a soil restoration device for environmental protection. Background Art

[0002] With the continuous acceleration of the industrialization process, due to reasons such as unreasonable mining of mineral resources and their smelting emissions, long-term sewage irrigation and sludge application to the soil, atmospheric deposition caused by human activities, application of chemical fertilizers and pesticides, etc., the soil pollution has become serious. Soil pollution remediation refers to the technical measures that, through physical, chemical, biological, and ecological principles and by adopting artificial control measures, reduce the concentration (activity) of soil pollutants, realize the harmlessness and stabilization of pollutants, and achieve the desired detoxification effect. Theoretically feasible remediation technologies include several categories such as phytoremediation, microbial remediation, chemical remediation, physical remediation, and comprehensive remediation. Some remediation technologies have entered the field application stage and achieved good results. Implementing soil remediation is of great significance for blocking pollutants from entering the food chain, preventing harm to human health, and promoting land resource protection and sustainable development. The research and development of this technology mainly focus on the remediation of soil polluted by biodegradable organic pollutants and heavy metals.

[0003] With the increasing attention of people to soil environmental problems and the advancement of modern agriculture, chemical remediation technology will play a greater role in the treatment of pesticide environmental pollution. However, there are also the following problems in the remediation process. Traditional chemical remediation technology sprays the remediation agent on the soil surface, but it cannot guarantee the spraying effect, and it cannot spray and remediate different land types, making it difficult to achieve good remediation effects. At the same time, there is also the problem that the soil areas are scattered and large machinery cannot enter, resulting in the inability to repair the soil in a timely manner. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background art, and to propose a soil restoration device for environmental protection.

[0010] In the above-mentioned environmental protection soil remediation device, traction plates are fixedly installed on both sides of the outer protective cylinder. Traction holes are opened inside one end of each traction plate away from the outer protective cylinder. The communication boxes are respectively fixedly installed on both sides of the outer protective cylinder. The liquid adding boxes are respectively fixedly installed on the tops of the two traction plates. Rectangular grooves are opened inside the bottoms of the outer protective cylinder and the arc-shaped placement frame, and the liquid spraying box is clamped and installed inside the rectangular grooves.

[0011] In the above-mentioned soil remediation device for environmental protection, the pedestal is fixedly installed at the top inside the outer protection cylinder. Thread holes are provided inside both of the two threaded hole seats, and the thread directions inside the thread holes are opposite.

[0019] 2. The moving wheels will rotate, driving the transmission gear to rotate, which in turn drives the one-way ratchet gear one to rotate, driving the threaded rod to rotate, causing the threaded hole seats to approach each other, making the push rod tend to be vertical, moving the sliding chute plate and the arc-shaped top pressing plate downward, and squeezing the repair liquid sac through the arc-shaped top pressing plate, ensuring that the repair liquid inside the repair liquid sac is stably sprayed out onto the surface of the soil to be repaired through the liquid spraying nozzles at the bottom of the liquid spraying box. Using the self-moving method to drive the internal structure reduces energy consumption compared to traditional mechanical transmission methods, and the moving speed of the device can be increased or decreased according to requirements, thereby controlling the spraying rate of the repair liquid and adjusting according to different soils, improving the use effect of the device;

[0020] 3. When the arc-shaped top pressing plate moves downward, it can pull the pulling cloth to drive the rotating sleeve to rotate on the outside of the connecting rod, causing the first arc-shaped side pressing plate to rotate, and the first arc-shaped side pressing plate and the second arc-shaped side pressing plate squeeze the repair liquid sac, ensuring that the repair liquid sac can be fully squeezed and the repair liquid inside the repair liquid sac is completely sprayed out, improving the use effect.

At the end of the arc-shaped side pressing plate one 16 away from the rotating sleeve 37, a limiting arc is fixedly installed, and one end of the arc-shaped side pressing plate two 17 is rotatably installed inside the limiting arc.

One end of the torsion spring 40 is fixedly installed on the outside of the connecting rod 39, and the other end of the torsion spring 40 is fixedly installed inside the rotating sleeve 37;

[0035] The top pressing assembly includes an arc-shaped top pressing plate 18 and a threaded rod 30. A chute plate 34 is fixedly installed at the top of the arc-shaped top pressing plate 18. An installation card slot 27 is opened at the top of the chute plate 34. Installation card seats 28 are symmetrically clamped and installed inside the installation card slot 27. Push rods 29 are movably installed inside the tops of the installation card seats 28. One end of the push rod 29 away from the installation card seat 28 is movably installed with a threaded hole seat 33. A support seat 32 is movably installed at the center of the threaded rod 30. A one-way ratchet gear one 22 is fixedly installed at one end of the threaded rod 30. A transmission gear 23 is engaged with the outside of the one-way ratchet gear one 22. A one-way ratchet gear two 38 is fixedly installed at the end of the threaded rod 30 away from the one-way ratchet gear one 22. The support seat 32 is fixedly installed at the top inside the outer protection cylinder 1. Threaded holes are opened inside both of the two threaded hole seats 33, and the thread directions inside the threaded holes are opposite. The thread directions at both ends of the threaded rod 30 are opposite. The two threaded hole seats 33 are threadedly connected to the outside of the threaded rod 30 through the threaded holes. The rotation directions of the one-way ratchet gear two 38 and the one-way ratchet gear one 22 are opposite. A connecting rotating column 13 is fixedly installed on the side of the one-way ratchet gear two 38 away from the threaded rod 30. A rotating handle 11 is fixedly installed at the end of the connecting rotating column 13 away from the one-way ratchet gear two 38. One end of one of the connecting rotating shafts 12 away from the moving wheel 8 is fixedly connected to one side of the transmission gear 23.

[0036] Among them, the traction plate 2 and the traction hole 3 can be used to externally connect traction equipment, and in cooperation with the moving wheels 8, the device can move on the land to be repaired, which is convenient to use and can improve the use effect of the device.

[0037] Among them, a liquid injection device can be externally connected through the liquid adding box 5 to inject the repair liquid into the inside of the liquid adding box 5. The repair liquid inside the liquid adding box 5 will enter the inside of the first liquid injection pipe 7, then enter the inside of the communication box 6, and finally be injected into the inside of the repair liquid bag 31 through the second liquid injection pipe 24. After the repair liquid is injected into the repair liquid bag 31, it can expand. After being squeezed by the side pressing assembly and the top pressing assembly, the repair liquid inside the repair liquid bag 31 will be sprayed out to the surface of the land to be repaired through the liquid spraying nozzles 10 at the bottom of the liquid spraying box 9. The microorganisms and medicaments in the repair liquid can repair the soil, improving the repair efficiency. The repair liquid is sprayed into the soil, reducing the waste of the liquid medicine and the risk of secondary pollution.

[0038] Among them, when the device moves, the moving wheels 8 will rotate, driving the transmission gear 23 to rotate, which in turn drives the one-way ratchet gear one 22 to rotate, driving the threaded rod 30 to rotate. Since both the one-way ratchet gear two 38 and the one-way ratchet gear one 22 rotate in one direction only and in opposite directions, the one-way ratchet gear two 38 will not rotate with the threaded rod 30. When the threaded rod 30 rotates, the two threaded hole seats 33 will approach each other, making the push rod 29 tend to be vertical, moving the chute plate 34 and the arc-shaped top pressing plate 18 downward, squeezing the repair liquid bag 31 through the arc-shaped top pressing plate 18, ensuring that the repair liquid inside the repair liquid bag 31 stably sprays out from the liquid spraying nozzle 10 at the bottom of the liquid spraying box 9 onto the land surface to be repaired. Driving the internal structure by its own movement reduces energy consumption compared to traditional mechanical transmission methods, and the moving speed of the device can be increased or decreased according to needs, thereby controlling the spraying rate of the repair liquid and adjusting according to different lands, improving the use effect of the device.

[0039] Among them, when the arc-shaped top pressing plate 18 moves downward, it can drive the rotating sleeve 37 to rotate on the outside of the connecting rod 39 by pulling the cloth 21, causing the arc-shaped side pressing plate one 16 to rotate, and the arc-shaped side pressing plate one 16 and the arc-shaped side pressing plate two 17 to squeeze the repair liquid bag 31, ensuring that the repair liquid bag 31 can be fully squeezed and the repair liquid inside the repair liquid bag 31 is completely sprayed out, improving the use effect.

[0040] Among them, when the repair liquid inside the repair liquid bag 31 is used up, the one-way ratchet gear two 38 can be rotated by rotating the handle 11 and the connecting rotating column 13, driving the threaded rod 30 to rotate, separating the threaded hole seats 33 from each other, moving the arc-shaped top pressing plate 18 upward, no longer squeezing the repair liquid bag 31, and under the action of the torsion spring 40, the rotating sleeve 37 is reset, and the arc-shaped side pressing plate one 16 and the arc-shaped side pressing plate two 17 no longer squeeze the repair liquid bag 31, facilitating the supply of repair liquid into the repair liquid bag 31 through the liquid adding box 5, and can be used repeatedly, improving the use effect.

[0041] Guide shafts two 42 are fixedly installed at the top of the connecting plate 14. Guide shafts one 19 are symmetrically fixedly installed at the top of the inner cavity of the outer protection cylinder 1. One end of the pulling cloth 21 away from the rotating sleeve 37 passes through the guide shaft two 42 and the guide shaft one 19 and is fixedly connected to both sides of the arc-shaped top pressing plate 18. Moving sliders 20 are fixedly installed on both sides of the arc-shaped top pressing plate 18. Moving chutes 25 are opened inside the side baffles 26, and the moving sliders 20 are slidably installed inside the moving chutes 25.

[0042] Among them, the pulling cloth 21 can be limited by the arranged guide shaft two 42 and guide shaft one 19, and the stable up and down movement of the arc top pressing plate 18 can be ensured by the arranged moving slider 20 and moving chute 25.

[0043] Both sides of the top of the outer protection cylinder 1 are fixedly installed with protective covers 4. The one-way ratchet gear two 38 and the one-way ratchet gear one 22 are respectively located inside the two protective covers 4. The two protective covers 4 can protect the one-way ratchet gear two 38 and the one-way ratchet gear one 22.

[0044] Further explanation, the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are well-known conventional means in the art.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
