Description

Technical Field

[0001] This invention relates to the field of land development and restoration technology, and in particular to a land development restoration device. Background Technology

[0002] Fragmentation work in land consolidation and restoration is an important part of the land development process. It aims to break down the original land to facilitate subsequent land use and construction. This work typically includes the following steps:

[0003] Land survey and assessment: Before carrying out land consolidation and restoration, a land survey and assessment is required to understand the physical properties, chemical properties, and environmental conditions of the land. This information is crucial for subsequent fragmentation work and the development of restoration plans.

[0004] Land breaking equipment selection: Choose appropriate land breaking equipment based on the characteristics and scale of the land. Common land breaking equipment includes excavators, bulldozers, and crushers. Selecting suitable equipment can improve work efficiency and quality.

[0005] Land fragmentation operations: Based on the fragmentation plan and design requirements, selected equipment is used to fragment the land. This may include clearing vegetation, demolishing buildings, and breaking up rock or concrete structures. Safety and environmental protection requirements must be observed during the operation to ensure its smooth progress.

[0006] Land crushing and gravel treatment: After land is crushed, a large amount of gravel and debris may be generated. This gravel needs to be processed and can be used for landfill, reuse, or sale. For projects with high environmental protection requirements, such as the construction of ecological parks or green spaces, screening and washing of the gravel can be considered to reduce the environmental impact.

[0007] Land remediation and restoration: After land fragmentation is completed, land remediation and restoration work is required to restore the land's functions and ecosystems. This may include measures such as land leveling, vegetation restoration, and soil improvement to protect land resources and provide sustainable land use.

[0008] The entire land consolidation and restoration process needs to be planned and implemented based on the specific project requirements and environmental conditions. During the work, the principles of environmental protection, resource utilization, and sustainable land use must be fully considered to ensure a balance between land development and protection.

[0009] Currently, soil, rocks, and plastic waste have diverse physical properties, necessitating a technology that can accurately distinguish and efficiently separate them, especially for small-diameter rocks and tiny plastic particles. Secondly, soil remediation requires removing pollutants without introducing new harmful substances, while also considering cost and time efficiency. Different types of pollution require different remediation methods, and selecting the most suitable combination of remediation technologies is a challenge. Finally, reducing secondary pollution and energy consumption is crucial for sustainable development. During separation and remediation, it is essential to avoid generating new pollutants while minimizing energy demand to reduce negative environmental impacts. Therefore, this device provides a land development remediation apparatus. Summary of the Invention

[0013] Furthermore, a placement plate is provided directly below the adhesive hanging rack, and the placement plate is mounted on the frame of the belt conveyor.

[0014] Furthermore, there is a gap between the first end of the inclined plate and the end of the belt conveyor, and this gap is a plastic object discharge cavity.

The air outlet of the powerful fan is arranged in a horizontal strip shape and faces the plastic object discharge cavity.

[0015] Furthermore, the compression and collection device includes a baffle, a multi-section telescopic electric cylinder, a compression plate, a compression frame, and a plastic bag hanger. The baffle is disposed between the soil cavity and the plastic cavity. The multi-section telescopic electric cylinder is disposed at the top of the inner wall of the plastic cavity. A compression groove is provided at the lower end of the plastic cavity. The compression plate is disposed on the output end of the multi-section telescopic electric cylinder, with the output end of the multi-section telescopic electric cylinder facing downwards. The compression frame is disposed at the lower end of the compression groove, and the plastic bag hanger is located directly below the compression frame.

[0016] Furthermore, a fixing plate is provided directly below the plastic bag hanger, and the fixing plate is mounted on the frame of the belt conveyor.

[0017] Furthermore, the high-pressure spraying device includes a first high-pressure spray nozzle, a second high-pressure spray nozzle, a connecting pipe, a water pump, a connecting pipe, and a storage box. The storage box is located at the bottom of the soil cavity. The first high-pressure spray nozzle is located on the inner wall of the soil cavity and faces the beginning of the filter screen. The second high-pressure spray nozzle is located beside the first high-pressure spray nozzle and faces the middle of the filter screen. The water pump is located outside the protective housing. The water pump and the storage box are connected by the connecting pipe. The first and second high-pressure spray nozzles are connected to the equipment by the connecting pipe.

[0018] Furthermore, the storage box has a base plate at the top with several holes, the soil collection rack is located directly above the base plate, and the protective shell has a magnetic door located next to the soil collection rack.

[0019] Furthermore, the crushing device includes roller crushing wheels, rotating shafts, crushing motors, and crushing feed plates. Two roller crushing wheels are provided, symmetrically arranged, located near the bottom of the stone cavity and rotatably connected. Two rotating shafts are provided, mounted on corresponding roller crushing wheels and passing through the protective housing outside it. Two crushing motors are provided, located outside the protective housing, with their output ends connected to the corresponding rotating shafts. The crushing feed plate is inclined and positioned at the bottom of the stone cavity.

[0020] Furthermore, a stone crushing and feeding chute is provided on the protective shell at the bottom of the stone cavity, and the stone crushing and feeding chute extends from the end of the crushing and feeding plate.

[0021] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0022] Firstly, removing plastic waste improves the soil's physical structure, increasing porosity and enhancing aeration and permeability. This benefits soil microbial activity and nutrient cycling, thereby improving soil fertility and providing better conditions for plant growth. Without the interference of plastic waste, soil moisture and nutrients can be distributed more evenly, promoting root absorption and growth, and ensuring soil ecological safety. Plastic waste may release harmful substances such as heavy metals and plasticizers, which can be toxic to soil organisms. Separation prevents these harmful substances from damaging the soil ecosystem, protects the living environment of soil microorganisms, earthworms, and other organisms, helps maintain soil ecological balance, promotes material cycling and energy flow in the soil, and enhances the soil's self-repair capacity.

[0023] Secondly, removing the mixture of plastic waste, stones, and soil makes the land cleaner, facilitating subsequent land leveling and landscaping, improving the quality and aesthetics of land development, and providing better foundational conditions for different land uses, such as residential, commercial, and agricultural construction. Separating the land development process allows for a more orderly process, reducing construction difficulties and delays caused by plastic waste and stones. This ultimately accelerates land development, improves project economic efficiency, and enhances the quality of land development.

[0024] Third, plastic waste is difficult to degrade in the natural environment, causing long-term pollution to soil, water, and air. Separating it can effectively reduce environmental pollution during land development, protect the ecological environment, prevent plastic waste from entering the food chain and threatening the health of humans and other organisms, promote resource recycling, and reduce the demand for raw materials, energy consumption, and greenhouse gas emissions, thereby maximizing resource utilization, conforming to the concept of sustainable development, and reducing environmental pollution.

[0025] Fourth, the stones can be used for other purposes: the separated stones can be classified according to their size, shape, and material for use in construction, road building, landscaping, and other fields, achieving rational utilization of resources and improving land development efficiency. Separating soil and stones during land development makes the process more efficient and orderly. The separated soil and stones can be treated and utilized separately according to different uses, improving the overall benefits of land resources.

[0026] Fifth, when the stones and accumulated soil are conveyed to the inclined plate by the belt conveyor, the water pump starts and sprays water from the storage box through the first and second high-pressure water spray nozzles. The stones and accumulated soil move downwards due to the inclined angle of the inclined plate. During this movement, the stones and accumulated soil are first sprayed by the first high-pressure water spray nozzle to remove the soil adhering to the stones and loosen the accumulated soil. Some smaller soil particles fall through the filter screen on the inclined plate into the soil cavity, and when sprayed by the second high-pressure water spray nozzle, the soil on the stones is almost completely removed. The clean material moves towards the crushing device, and the loose soil, after being sprayed again, almost falls through the filter screen on the inclined plate into the soil cavity. Most of the sprayed water flows through the filter screen into the stone cavity, and a small portion flows into the crushing device. The soil and sprayed water flowing into the stone cavity then flow into the soil collection bag. The sprayed water seeps out of the soil collection bag and flows into the storage box through the holes on the bottom plate, thus achieving the separation and storage of soil, plastic waste, and stones. The sprayed water flowing back into the storage box achieves the effect of sprayed water recycling and reuse, reducing resource waste and improving operation efficiency. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0044] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] This invention provides a land remediation device for land development, comprising a protective shell 1, a belt conveyor 2 for conveying objects, a powerful blower 3 for blowing objects, a blade cleaner 4 for cleaning adhering materials on the belt conveyor 2, an adhering material collection device 5, a compression collection device 6 for compressing lightweight plastic films, a powerful spraying device 7 for spraying soil and dust generated from crushing, a soil collection rack 78 for hanging soil collection bags, and a crushing device 8 for crushing hard rocks. The upper end of the protective shell 1... The system includes a feed inlet 11, with the conveying platform of the belt conveyor 2 located inside the protective housing 1 and directly below the feed inlet 11. The adhesive collection device 5 is located below the blade cleaner 4. The protective housing 1 has an inclined plate 12 for soil and rock movement, which is inclined. A filter screen 13 is located in the middle of the inclined plate 12. The spraying end of the powerful spraying device 7 faces the filter screen 13. The protective housing 1 is divided into three cavities: a rock cavity 14, a soil cavity 15, and a plastic cavity 16. The filter screen 13 is connected to the soil cavity 15.

[0046] This device can separate and collect soil, plastic waste, and stones. After removing plastic waste, the physical structure of the soil is improved, porosity increases, and aeration and permeability are enhanced. This is beneficial to the activity of microorganisms and nutrient cycling in the soil, thereby improving soil fertility and providing better conditions for plant growth. Without the interference of plastic waste, the water and nutrients in the soil can be distributed more evenly, promoting the absorption and growth of plant roots and ensuring soil ecological safety. Plastic waste may release harmful substances, such as heavy metals and plasticizers, which can be toxic to organisms in the soil.

[0047] The clay particles have a diameter of less than 0.002 mm; the silt particles have a diameter between 0.002 mm and 0.05 mm; the sand particles have a diameter between 0.05 mm and 2 mm. The filter screen 13 on the inclined plate 12 in this device has a mesh diameter of 3 mm, which allows the soil to pass through smoothly.

[0048] Preferably, the protective housing 1 is provided with an adhesive discharge trough 17 and is located next to the blade cleaner 4. The adhesive collection device 5 is provided at the lower end of the adhesive discharge trough 17. The adhesive collection device 5 includes an adhesive discharge frame 51 and an adhesive hanging rack 52. The adhesive discharge frame 51 is provided at the lower end of the adhesive discharge trough 17, and the adhesive hanging rack 52 is connected to the outside of the protective housing 1 and is located directly below the adhesive discharge frame 51.

[0049] Because soil is adhesive, it easily adheres to the belt conveyor 2 during the soil transport process. Therefore, this device is equipped with a blade cleaner 4. When the belt conveyor 2 transports soil, the adhered soil is scraped off by the blade cleaner 4 and falls into the adhered material discharge chute 17. The soil is then collected by the adhered material bag, which avoids damage to the equipment and improves the soil collection process.

[0050] Preferably, a placement plate 53 is provided directly below the adhesive hanging rack 52 and the placement plate 53 is set on the frame of the belt conveyor 2. There is a gap between the first end of the inclined plate 12 and the end of the belt conveyor 2 and the gap is the plastic object unloading cavity 21. The height of the conveying platform of the belt conveyor 2 is higher than the height of the first end of the inclined plate 12. The air outlet of the powerful fan 3 is arranged in a horizontal strip shape and faces the plastic object unloading cavity 21.

[0051] When carrying out soil remediation work, to facilitate subsequent soil collection, soil collection bags are first placed on soil collection racks 78 with the bottom of the bags resting on the base plate 77; plastic garbage bags are placed on plastic bag racks 65 with the bottom of the bags resting on the fixing plate 66; and adhesive bags are placed on adhesive racks 52 with the bottom of the bags resting on the placement plate 53. Then, workers use an excavator to dig up the soil according to the land to be remediated. After the soil is dug up, it will contain plastic waste and stones, which are poured into the protective shell 1 through the feed inlet 11 at the top. After the soil enters the interior through the feed inlet 11, it falls directly into the conveyor belt 2 inside the protective shell 1. The start of the conveyor belt 2 will cause the soil to move towards the inclined plate 12. When the conveyor belt 2 starts, the powerful fan 3 also starts simultaneously. Due to the inertia of the conveyor belt 2, heavier objects will fall in a parabolic arc after leaving the conveyor belt 2, while lighter objects will not fall as obviously. After the lighter objects leave the conveyor belt 2, the blowing force of the powerful fan 3 is aimed at the plastic object discharge cavity 21. Therefore, lighter objects, such as plastic waste, will enter the plastic cavity 16, while heavier objects, such as stones and piled soil, will fall directly onto the inclined plate 12. At this time, the separation of soil and plastic waste is completed. The process and operation are relatively simple, and the position of the entire equipment and the effect it brings are just right.

[0052] After plastic waste enters the plastic cavity 16, it falls into the plastic garbage bag through the compression groove 161 at the lower end of the plastic cavity 16. The bottom of the plastic garbage bag is supported by the fixed plate 66, while the hanging plate provides a hanging function. The two complement each other, which can ensure that the garbage does not shift during the collection process and can be collected more effectively. Since most plastic waste is expandable, it takes up a lot of space. After entering the plastic garbage bag, the plastic garbage bag may need to be replaced after only a small amount of plastic waste has been collected. At this time, this device can activate the multi-section telescopic electric cylinder 62 to drive the compression plate 63 on the output end of the multi-section telescopic electric cylinder 62 to move downward, that is, towards the compression groove 161. This allows the compression plate 63 to extend into the compression groove 161 and into the plastic garbage bag to compress the plastic waste inside the plastic garbage bag. This increases the garbage storage capacity inside the plastic garbage bag, reduces the number of times the plastic garbage bag needs to be replaced, and improves the collection efficiency of plastic waste.

[0053] After plastic waste is removed, the physical structure of the soil is improved, porosity increases, and aeration and permeability are enhanced. This is beneficial to the activity of soil microorganisms and nutrient cycling, thereby improving soil fertility and providing better conditions for plant growth. Without the interference of plastic waste, water and nutrients in the soil can be distributed more evenly, promoting root absorption and growth, and ensuring soil ecological safety. Plastic waste may release harmful substances such as heavy metals and plasticizers, which can be toxic to soil organisms. Separation can prevent these harmful substances from damaging the soil ecosystem, protect the living environment of soil microorganisms, earthworms, and other organisms, help maintain soil ecological balance, promote the cycling of materials and energy flow in the soil, and improve the soil's self-repair capacity.

[0054] Plastic waste is difficult to degrade in the natural environment and causes long-term pollution to soil, water, and air. Separating it can effectively reduce environmental pollution during land development, protect the ecological environment, prevent plastic waste from entering the food chain and threatening the health of humans and other organisms, promote resource recycling, and reduce the demand for raw materials, energy consumption, and greenhouse gas emissions, thereby maximizing resource utilization, conforming to the concept of sustainable development, and reducing environmental pollution.

[0055] Removing the mixture of plastic waste, stones, and soil makes the land cleaner, facilitating subsequent land leveling, landscaping, and other work. This improves the quality and aesthetics of land development, providing better foundational conditions for different land uses, such as residential, commercial, and agricultural construction. Separating the land for these uses also speeds up the development process, making it more orderly and reducing construction difficulties and delays caused by plastic waste and stones. Ultimately, this accelerates land development, increases project economic benefits, and improves the quality of land development.

[0056] Preferably, the compression and collection device 6 includes a baffle 61, a multi-section telescopic electric cylinder 62, a compression plate 63, a compression frame 64, and a plastic bag hanger 65. The baffle 61 is disposed between the soil cavity 15 and the plastic cavity 16. The multi-section telescopic electric cylinder 62 is disposed at the top of the inner wall of the plastic cavity 16. A compression groove 161 is provided at the lower end of the plastic cavity 16. The compression plate 63 is disposed on the output end of the multi-section telescopic electric cylinder 62, and the output end of the multi-section telescopic electric cylinder 62 is downward. The compression frame 64 is disposed at the lower end of the compression groove 161. The plastic bag hanger 65 is located directly below the compression frame 64.

[0057] The plastic bag hanger 65 is provided with a fixing plate 66 directly below it, and the fixing plate 66 is mounted on the frame of the belt conveyor 2.

[0058] The high-pressure spraying device 7 includes a first high-pressure spray nozzle 71, a second high-pressure spray nozzle 72, a connecting pipe 73, a water pump 74, a connecting pipe 75, and a storage box 76. The storage box 76 is located at the bottom of the soil cavity 15. The first high-pressure spray nozzle 71 is located on the inner wall of the rock cavity 14 and faces the beginning of the filter screen 13. The second high-pressure spray nozzle 72 is located beside the first high-pressure spray nozzle 71 and faces the middle of the filter screen 13. The water pump 74 is located outside the protective housing 1. The water pump 74 and the storage box 76 are connected by the connecting pipe 75. The first high-pressure spray nozzle 71 and the second high-pressure spray nozzle 72 are connected to the equipment by the connecting pipe 73.

[0059] The storage box 76 has a base plate 77 at its upper end and several holes on the base plate 77. The soil collection rack 78 is located directly above the base plate 77. The protective shell 1 has a magnetic door 18, which is located next to the soil collection rack 78.

[0060] When the stones and accumulated soil are conveyed onto the inclined plate 12 by the belt conveyor 2, the water pump 74 starts and sprays water from the storage box 76 through the first high-pressure water spray nozzle 71 and the second high-pressure water spray nozzle 72. The stones and accumulated soil move downwards due to the inclination angle of the inclined plate 12. During this movement, the stones and accumulated soil are first sprayed by the first high-pressure water spray nozzle 71 to remove the soil adhering to the stones and loosen the accumulated soil. Some smaller soil particles fall through the filter screen 13 on the inclined plate 12 into the soil cavity 15. When sprayed by the second high-pressure water spray nozzle 72, the soil on the stones is almost completely removed, and the stones move towards the crushing device 8. The loosened soil, after being impacted by the spray again, almost passes through the filter screen 13 on the inclined plate 12. 3. The water falls into the soil cavity 15, while most of the sprayed water flows into the stone cavity 14 through the filter screen 13, and a small part flows into the crushing device 8. After the soil and sprayed water flow into the stone cavity 14, they flow into the soil collection bag. The sprayed water will seep out of the soil collection bag and flow into the storage box 76 through the holes on the bottom plate 77. This achieves the separation and storage of soil, plastic waste and stones. The sprayed water flows back into the storage box 76, which achieves the effect of sprayed water recycling and reuse, reduces resource waste and improves operation efficiency.

[0061] Separating soil from rocks after watering has the following advantages:

[0062] I. Beneficial for improving soil quality

[0063] Improving soil fertility: After separation, the pure soil contains fewer impurities, which is conducive to the activity of soil microorganisms and the release of nutrients. Microorganisms can decompose organic matter and convert it into nutrients that plants can absorb, thereby improving soil fertility and promoting plant growth and development.

[0064] Improved soil structure: Without the interference of stones, soil particles can arrange themselves better, forming a looser, more aerated, and water-retentive soil structure. This soil structure is conducive to root growth and extension, improving the efficiency of plant absorption of water and nutrients.

[0065] Facilitates soil improvement: When improving soil, such as by adding organic fertilizers or soil conditioners, the absence of stones allows the improving substances to be distributed more evenly in the soil, thus improving the improvement effect.

[0066] II. Facilitating agricultural production operations

[0067] Facilitates cultivation: During cultivation, soil without stones is easier to plow and harrow, reducing wear and damage to agricultural machinery. It also allows seeds to make better contact with the soil, improving germination rate and uniform seedling emergence.

[0068] Facilitates irrigation and drainage: The separated soil has better permeability, allowing water to penetrate more evenly during irrigation and preventing localized waterlogging or drought caused by stones clogging the soil. In terms of drainage, excess water can be discharged more smoothly, preventing overly wet soil from harming plants.

[0069] Facilitates field management: The absence of stones during field management operations such as weeding, fertilizing, and pest and disease control can improve work efficiency and reduce labor intensity.

[0070] III. Protecting the Ecological Environment

[0071] Reducing soil erosion: After the rocks separate from the soil, the soil becomes more stable and less prone to erosion by rainwater. This helps protect the surrounding ecological environment and reduces siltation in rivers, lakes, and other water bodies.

[0072] Reducing the risk of soil pollution: If the stones contain harmful substances, such as heavy metals, separating them from the soil can reduce the risk of soil pollution. It also facilitates targeted treatment and remediation of contaminated soil.

[0073] IV. Rational Utilization of Resources

[0074] Stones can be used for other purposes: the separated stones can be classified according to their size, shape and material, and used in fields such as construction, road building, and landscape construction, so as to realize the rational use of resources.

[0075] Improving land development efficiency: Separating soil and rocks during land development can make the process more efficient and orderly. The separated soil and rocks can be treated and utilized separately according to different uses, thereby improving the overall benefits of land resources.

[0076] Preferably, the crushing device 8 includes roller crushing rollers 81, rotating shafts 82, crushing motors 83, and crushing feed plates 84. Two roller crushing rollers 81 are provided, symmetrically arranged, located near the bottom of the stone cavity 14, and both are rotatably connected. Two rotating shafts 82 are provided, mounted on corresponding roller crushing rollers 81, and both pass through the protective housing 1 and are located outside it. Two crushing motors 83 are provided, located outside the protective housing 1, and their output ends are connected to the corresponding rotating shafts 82. The crushing feed plate 84 is inclined and positioned at the bottom of the stone cavity 14. A stone crushing feed trough 19 is provided on the protective housing 1 at the bottom of the stone cavity 14, and the stone crushing feed trough 19 extends from the end of the crushing feed plate 84.

[0077] After the soil-removed stones enter the crushing device 8, the two crushing motors 83 start, driving the corresponding rotating shafts 82 at their output ends to rotate symmetrically inward. The rotation of the two rotating shafts 82 drives the two crushing rollers 81 to rotate symmetrically inward. Therefore, when the stones fall onto the two crushing rollers 81, the symmetrical inward rotation of the rollers achieves the crushing operation. The crushed stones flow out through the crushing discharge plate 84 and the stone crushing discharge trough 19 for storage. The separated stones can be classified and utilized according to their size, shape, and material. For example, larger stones can be used in construction and road building projects; smaller stones can be used as aggregate in concrete. This fully utilizes the resource value of stones, reduces the exploitation of natural resources, and pure stones also have applications in specific industrial fields, such as glass manufacturing and ceramic production. Separation improves the quality of the stones, meets the needs of different industries, and facilitates stone processing and management without the mixing of plastic waste, making stone processing and management more convenient. More efficient crushing and screening processes can be adopted to improve the processing efficiency and quality of stone, reduce the environmental pollution risk caused by mixing stone with plastic waste, and lower processing costs.
