Description

Technical Field

[0001] The present invention relates to the technical field of land development and restoration, and in particular to a land development and restoration device. Background Art

[0002] Land restoration and fragmentation is an important task in the land development process, which aims to fragment the original land for subsequent land use and construction. This work usually includes the following steps:

[0003] Land survey and assessment: Before land remediation and restoration, land survey and assessment are required to understand the physical properties, chemical properties and environmental conditions of the land. This information is very important for the subsequent fragmentation work and the formulation of restoration plans.

[0004] Land crushing equipment selection: According to the characteristics and scale of the land, choose the appropriate land crushing equipment. Common land crushing equipment includes excavators, bulldozers, crushers, etc. Choosing appropriate equipment can improve work efficiency and quality.

[0005] Land crushing operation: According to the crushing plan and design requirements, the selected equipment is used to crush the land. This may include clearing vegetation, demolishing buildings, breaking rocks or concrete structures, etc. During the operation, attention should be paid to safety and environmental protection requirements to ensure the smooth progress of the work.

[0006] Land Gravel Treatment: After the land is broken, a large amount of gravel and debris may be generated. These gravels need 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, it is possible to consider screening and washing the gravels to reduce the impact on the environment.

[0007] Land restoration and recovery: After land fragmentation, land restoration and recovery are needed to restore the land’s functions and ecosystems. This may include land leveling, vegetation restoration, soil improvement and other measures to protect land resources and provide sustainable land use.

[0008] The entire land consolidation and restoration work needs to be planned and implemented according to the requirements of the specific project and environmental conditions. When carrying out the work, it is necessary to fully consider the principles of environmental protection, resource utilization and sustainable use of land to ensure a balance between land development and protection.

Thereby speeding up the progress of land development, improving the economic benefits of the project, and improving the quality of land development.

[0024] Third, material waste is difficult to degrade in the natural environment and will cause long-term pollution to the soil, water and air. Separating it can effectively reduce environmental pollution in the process of land development, protect the ecological environment, prevent plastic waste from entering the food chain and threatening the health of humans and other organisms, and promote resource recycling. The separated plastic waste can be recycled and reused, reducing the demand for raw materials, reducing energy consumption and greenhouse gas emissions, and maximizing the use of resources, which is in line with the concept of sustainable development and reduces 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, and used in the fields of construction, road construction, landscape construction, etc., to achieve the rational use of resources and improve the efficiency of land development: in the process of land development, separating soil and stones can make the development work more efficient and orderly.

[0026] Fifth, when the stones and the accumulated soil are transported to the inclined plate by the operation of the belt conveyor, the water pump is started to spray the water in the storage box through the first high-pressure spray water nozzle and the second high-pressure spray water nozzle. The stones and the accumulated soil will move downward through the inclination angle of the inclined plate. During the movement, the stones and the accumulated soil will first be sprayed by the first high-pressure spray water nozzle to remove and separate the soil adhering to the stones, and the accumulated soil will be flushed and loosened. Some smaller soil will fall into the soil cavity through the filter net on the inclined plate, and then be sprayed by the second high-pressure spray water nozzle. The soil on the stones is almost removed. The soil will move cleanly towards the crushing device, and the loose soil will be impacted by the spraying again. The soil will almost fall into the soil cavity through the filter on the inclined plate, and most of the sprayed water will flow into the stone cavity through the filter, and a small part will flow into the crushing device. After the soil and the spraying water flow into the stone cavity, they will flow into the soil collection bag, and the spraying water will penetrate out of the soil collection bag and flow into the storage box through the holes on the bottom plate, thereby realizing the separation and storage of soil, plastic waste and stone.

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0046] This device can separate and collect soil, plastic waste and stones. After removing plastic waste, the physical structure of the soil is improved, the porosity is increased, and the air permeability and water permeability are enhanced, which is conducive to the activity of microorganisms and the circulation of nutrients 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 more evenly distributed, promoting the absorption and growth of plant roots and ensuring the ecological safety of the soil. Plastic waste may release harmful substances, such as heavy metals, plasticizers, etc., which may poison organisms in the soil.

[0047] The diameter of clay particles is less than 0.002 mm; the diameter of silt particles is between 0.002 mm and 0.05 mm; the diameter of sand particles is between 0.05 mm and 2 mm. The mesh diameter of the filter screen 13 on the inclined plate 12 in this device is 3 mm, which can smoothly facilitate the passage of soil.

[0048] Preferably, the protective shell 1 is provided with an adhesion material discharge trough 17 and is located beside the knife-type sweeper 4, the adhesion collection device 5 is arranged at the lower end of the adhesion material discharge trough 17, and the adhesion collection device 5 includes an adhesion material discharge frame 51 and an adhesion material hanging rack 52, the adhesion material discharge frame 51 is arranged at the lower end of the adhesion material discharge trough 17, and the adhesion material hanging rack 52 is connected to the outside of the protective shell 1 and is located directly below the adhesion material discharge frame 51;

[0049] Since the soil is sticky, it is easy to adhere to the belt conveyor 2 during the soil transportation process. Therefore, the device is provided with a knife-type sweeper 4. When the belt conveyor 2 transports the soil, the adhered soil will be scraped off after passing through the knife-type sweeper 4 and fall into the adhesion discharge chute 17, and the adhesion bag will be used for collection, thereby avoiding damage to the equipment and better improving the soil collection operation.

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

[0051] When the soil is being developed and repaired, first, in order to facilitate the subsequent soil collection operation, the soil collection bag can be placed on the soil collection hanging rack 78 and the bottom of the soil collection bag is located on the bottom plate 77, the plastic garbage bag can be placed on the plastic bag hanging rack 65 and the bottom of the plastic garbage bag is located on the fixed plate 66, and the adhesive bag can be placed on the adhesive hanging rack 52 and the bottom of the adhesive bag is located on the placement plate 53. Then, the staff will dig up the soil by excavating according to the land to be repaired. After the soil is dug up, plastic garbage and stones will be mixed inside the soil, and they will be poured into the soil through the feed port 11 at the upper end of the protective shell 1. After the soil enters the interior through the feed port 11, it will just fall to the conveying part of the belt conveyor 2 inside the protective shell 1. The start of the belt conveyor 2 will drive the soil to be conveyed in the direction of the inclined plate 12. When the belt conveyor 2 is started, the synchronous powerful fan 3 is also started. Through the conveying movement inertia of the belt conveyor 2, the heavier objects will have a parabolic arc falling trajectory when they leave the belt conveyor 2, while the lighter objects are not so obvious when they leave the belt conveyor 2. After the lighter objects leave, the blowing force of the powerful fan 3 is just aimed at the position of the plastic object unloading cavity 21. Therefore, the lighter objects, such as: plastic garbage, will enter the plastic cavity 16, and the heavier objects, such as: stones and accumulated soil will just fall on the inclined plate 12. At this time, the separation operation of soil and plastic garbage is completed, and the process and operation method are relatively simple, and the position of the entire equipment and the effect brought are just right;

[0052] After the plastic waste enters the plastic cavity 16, it will fall into the plastic waste bag through the compression groove 161 at the lower end of the plastic cavity 16. The bottom of the plastic waste bag is located on the fixed plate 66 to provide a support effect, while the hanging plate 66 provides a hanging effect. The two complement each other and can achieve the effect of better collection without displacement during the waste collection process. Since most plastic waste is expanded material, it occupies a large space. After entering the plastic waste bag, the plastic waste bag may not be collected much and needs to be replaced. At this time, the device can start 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, to move toward the compression groove 161, so that the compression plate 63 extends into the compression groove 161 and enters the plastic waste bag to compress the plastic waste inside the plastic waste bag, thereby increasing the waste storage capacity inside the plastic waste bag, reducing the number of times the plastic waste bag is replaced, and improving the collection effect of plastic waste.

[0053] After removing plastic waste from the soil, the soil's physical structure is improved, the porosity is increased, and the air permeability and water permeability are enhanced, which is conducive to the activity of microorganisms and the circulation of nutrients 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 more evenly distributed, promoting the absorption and growth of plant roots and ensuring the ecological safety of the soil. Plastic waste may release harmful substances such as heavy metals and plasticizers, which can poison organisms in the soil. After separation, these harmful substances can avoid damage to the soil ecosystem, protect the living environment of microorganisms, earthworms and other organisms in the soil, help maintain the ecological balance of the soil, promote the circulation of materials and energy flow in the soil, and improve the self-repairing ability of the soil;

[0054] Plastic waste is difficult to degrade in the natural environment and will cause long-term pollution to the soil, water and air. Separating it can effectively reduce environmental pollution in the process of land development, protect the ecological environment, prevent plastic waste from entering the food chain and threatening the health of humans and other organisms, and promote resource recycling. Separated plastic waste can be recycled and reused, reducing the demand for raw materials, reducing energy consumption and greenhouse gas emissions, and maximizing the use of resources, which is in line with the concept of sustainable development and reduces environmental pollution.

[0055] Removing the mixture of plastic waste, stones and soil makes the land purer, which is conducive to the subsequent land leveling, greening and other work, improves the quality and aesthetics of land development, and provides better basic conditions for different uses of land, such as building residential buildings, commercial facilities, farmland, etc., speeding up the progress of land development. Separation work can make the land development process more orderly and reduce construction difficulties and delays caused by interference from plastic waste and stones. Thereby speeding up the progress of land development, improving the economic benefits of the project, and improving the quality of land development.

[0060] When the stones and the accumulated soil are transported to the inclined plate 12 by the operation of the belt conveyor 2, the water pump 74 is started to spray the water in 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 the accumulated soil will move downward through the inclined angle of the inclined plate 12. During the movement, the stones and the accumulated soil will first be sprayed by the first high-pressure water spray nozzle 71 to remove and detach the soil adhering to the stones, and the accumulated soil will be loosened. Some smaller soil will fall into the soil cavity 15 through the filter screen 13 on the inclined plate 12, and then be sprayed by the second high-pressure water spray nozzle 72. The soil on the stones is almost completely removed and moves toward the crushing device 8, and the loose soil will pass through the filter screen 1 on the inclined plate 12 after being sprayed again. 3 falls into the soil cavity 15, and 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 the sprayed water flow into the stone cavity 14, they flow into the soil collection bag, and the sprayed water penetrates out of the soil collection bag and flows into the storage box 76 through the holes on the bottom plate 77, thereby realizing the separation and storage of soil, plastic waste and stones. The sprayed water flows back into the storage box 76, which plays the effect of recycling and reusing the sprayed water, reducing the waste of resources and improving the operation efficiency.

[0061] Separating the soil from the stone after watering has the following benefits:

[0062] 1. It is beneficial to improve soil quality

[0063] Improve soil fertility: After separation, the impurities in the pure soil are reduced, which is conducive to the activity of microorganisms in the soil and the release of nutrients. Microorganisms can decompose organic matter and convert it into nutrients that can be absorbed by plants, thereby improving the fertility level of the soil and promoting the growth and development of plants.

[0064] Improve soil structure: Without the interference of stones, soil particles can be better arranged and combined to form a looser, more breathable and water-retaining soil structure. Such a soil structure is conducive to the growth and extension of the root system and improves the efficiency of plants' absorption of water and nutrients.

[0065] Facilitates soil improvement: When improving the soil, such as adding organic fertilizers, soil conditioners, etc., the absence of stones can make the improved materials more evenly distributed in the soil, thereby improving the improvement effect.

[0066] 2. Convenient agricultural production operations

[0067] Conducive to farming: During the farming process, soil without stones is easier to plow and harrow, reducing the wear and damage of agricultural machinery. At the same time, it can also make seeds better contact with the soil, improve germination rate and uniformity of emergence.

[0068] Easy to irrigate and drain: The separated soil has better permeability, and water can penetrate into the soil more evenly during irrigation, avoiding local waterlogging or drought caused by stone blockage. In terms of drainage, it can also drain excess water more smoothly to prevent the soil from being too wet and causing harm to plants.

[0069] Convenient field management: When performing field management operations such as weeding, fertilizing, and pest control, the absence of stone interference can improve work efficiency and reduce labor intensity.

[0070] III. Protecting the Ecological Environment

[0071] Reduce soil erosion: After the stones are separated from the soil, the stability of the soil is enhanced, and it is not easy to cause soil erosion in the case of rain erosion, etc. This helps to protect the surrounding ecological environment and reduce the siltation of rivers, lakes and other water bodies.

[0072] Reduce the risk of soil pollution: If the stone contains harmful substances, such as heavy metals, etc., the risk of soil pollution can be reduced after it is separated from the soil. At the same time, it is also convenient for targeted treatment and restoration 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 construction, road construction, landscape construction and other fields to achieve rational use of resources.

[0075] Improve land development efficiency: In the process of land development, separating soil and stone can make the development work more efficient and orderly. The separated soil and stone can be processed and utilized separately according to different purposes, thus improving the comprehensive benefits of land resources.

[0076] Preferably, the crushing device 8 includes a roller crushing roller 81, a rotating shaft 82, a crushing motor 83 and a crushing discharge plate 84, wherein two roller crushing rollers 81 are provided, and the two roller crushing rollers 81 are symmetrically arranged, and the two roller crushing rollers 81 are located near the bottom of the stone cavity 14 and are both rotatably connected, and two rotating shafts 82 are provided, and the two rotating shafts 82 are arranged on the corresponding roller crushing rollers 81 and both pass through the protective shell 1 and are located outside thereof, and two crushing motors 83 are provided, and the two crushing motors 83 are arranged outside the protective shell 1 and the output ends of the two crushing motors 83 are connected to the corresponding rotating shafts 82, and the crushing discharge plate 84 is obliquely arranged at the bottom of the stone cavity 14, and a stone crushing discharge trough 19 is provided on the protective shell 1 at the bottom of the stone cavity 14, and the end of the crushing discharge plate 84 extends out of the stone crushing discharge trough 19;

[0077] When the stones without soil enter the crushing device 8, the two crushing motors 83 are started to drive the corresponding rotating shafts 82 on the output ends of the corresponding crushing motors 83 to rotate symmetrically inwards, and the two rotating shafts 82 rotate to drive the two roller crushing rollers 81 to rotate symmetrically inwards. Therefore, after the stones fall onto the two roller crushing rollers 81, the symmetrical inward rotation of the two roller crushing rollers 81 realizes the crushing operation of the stones, and the crushed stones will flow out through the crushing discharge plate 84 and the stone crushing discharge trough 19 for storage and placement. The separated stones can be classified and utilized according to their size, shape and material. For example, larger stones can be used for construction, road construction and other projects; smaller stones can be used as aggregates for concrete.
