Description

Technical Field

[0001] The present invention relates to the technical field of soil treatment, and in particular to a soil treatment and environmentally friendly restoration system and restoration method. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. The working principle of soil remediation is to crush and screen the contaminated soil, clean it with professional chemical detergents, and then dehydrate the cleaned soil and restore it to its previous location. In this way, the repaired soil meets the use standards and is only slightly higher in humidity.

[0003] In order to complete the remediation of the above steps, Chinese patent publication number CN209647207U discloses a hand-push contaminated soil restoration and environmental protection management device, including a soil remediation box, an excavation device, a reinforcement plate, a soil inlet pipe, a transmission box, a first driven shaft, an anti-skid wheel, a driving shaft, a second driven shaft, an unearthed pipe and a hand push frame. A transmission box is arranged at the bottom of the soil remediation box, and the inner cavity of the soil remediation box is divided into a soil inlet lifting chamber, a blending chamber and an unearthed lifting chamber by two groups of partitions. The soil inlet lifting chamber, the blending chamber and the unearthed lifting chamber are respectively provided with a first driven shaft, a driving shaft and a second driven shaft. Working process: the soil is lifted from the bottom of the soil inlet lifting chamber to the blending chamber and is first stirred. The soil is fully mixed and stirred with the medicine solution in the blending chamber, and then the soil enters the bottom of the unearthed lifting chamber to be lifted and stirred again, and finally falls back to the ground from the unearthed pipe. The soil is fully stirred in a limited space, which is beneficial to reducing the volume of the device and reducing the weight.

[0004] However, the existing remediation methods do not extract the mixed liquid medicine, and the soil that finally falls back to the ground contains the liquid medicine, which will affect the final remediation quality. This is also the disadvantage of most mobile integrated soil remediation equipment. Once the liquid medicine is extracted quickly, it is difficult to ensure the process of soil and liquid medicine reaction, which will have a greater impact on the remediation quality. Therefore, many devices do not extract the liquid medicine.

[0005] In view of this, it is urgent to propose a soil management and environmental protection restoration system that overcomes the above-mentioned drawbacks. Summary of the invention

[0006] The purpose of the present invention is to provide a soil treatment and environmental protection restoration system and restoration method to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, one of the purposes of the present invention is to provide a soil treatment and environmental protection restoration system, which includes a traveling system and a shoveling system and a soil restoration system mounted on the traveling system. The shoveling system shovels the soil on the ground on the path of the traveling system and transports it upward. The soil restoration system includes a soaking box for receiving the soil transported by the shoveling system. A heat flow output cover is provided on one side of the soaking box for outputting the soil. A conveyor belt group is provided between the soaking box and the heat flow output cover. The soil in the soaking box is transported to the heat flow output cover through the conveyor belt group. During the transportation process, the soaking box and the heat flow output cover separate the conveyor belt group into two independent spaces. The two independent spaces are:

[0008] The infiltration space is located within the infiltration box, and the spray end arranged in the infiltration space sprays the liquid medicine so that the liquid medicine is immersed in the soil without flowing out;

[0009] The dehydration space is located within the range of the heat flow output hood, in which the liquid medicine is separated from the soil, and the dehydrated soil falls back to the ground with the help of a conveyor belt group.

[0010] As a further improvement of the present technical solution, the traveling system includes a traveling base, a bracket for carrying an earthmoving system and a traveling component, the bracket is arranged in the traveling direction of the traveling base, and the traveling power of the traveling base is output through the traveling component arranged at the bottom thereof.

[0011] As a further improvement of the present technical solution, the shoveling system includes a side plate and a shoveling belt rotating around the periphery of the side plate. The shoveling belt rotates around the periphery of the side plate. A shovel body is arranged outside the shoveling belt. When the shoveling system moves synchronously with the traveling base, one end of the shoveling belt contacts the ground so as to shovel out the soil by utilizing the rotating shovel body and transport the shoveled soil.

[0012] As a further improvement of the technical solution, the top of the impregnation box is provided with an inlet for accessing the soil, the impregnation box is provided with an impregnation cavity connected to the inlet, the impregnation space is formed by the impregnation cavity, a spray pipe is provided from the outside into the impregnation cavity, and a spray head forming a spray end is provided on the spray pipe;

[0013] The outer end of the spray pipe is connected with a liquid storage tank, and under the action of a negative pressure pump arranged in the liquid storage tank, the liquid medicine in the liquid storage tank is sprayed out through the spray head.

[0014] As a further improvement of the present technical solution, the heat flow output hood is located on the conveying path of the conveyor belt group to form a heat flow cavity, and a dehydration space is formed through the heat flow cavity. The dehydration space has a hot air flow passing through the conveyor belt group, and the hot air flow heats and evaporates the medicine.

[0015] As a further improvement of the technical solution, the conveyor belt group is composed of a soaking conveyor belt and a drainage belt, and the soaking conveyor belt and the drainage belt rotate independently, wherein:

[0016] The conveying surface of the impregnation conveyor belt is in a sealed state, so that the soil mixed with the liquid medicine in the impregnation space is conveyed through the impregnation conveyor belt, and the liquid medicine and the soil are allowed to stand still during the conveying stage by using the impregnation conveyor belt in a sealed state;

[0017] The conveying surface of the leachate belt is in a permeable state. The leachate belt receives the soil transported by the soaked conveyor belt and transports the soil to the dehydration space. During the transportation process, the liquid medicine attached to the surface of the soil flows out of the conveying surface of the leachate belt. At the same time, the hot air flow in the dehydration space evaporates the liquid medicine soaked in the soil, and the hot air flow is output vertically downward.

[0018] As a further improvement of the technical solution, the bottom of the impregnation box is provided with an access port on the material receiving side, and an access port is opened on the opposite side of the access port. The impregnation conveyor belt passes through the access port from the outside and extends to the side where the access port is located.

[0019] As a further improvement of the present technical solution, a conveying chamber is arranged on the traveling base, the bottom of the conveying chamber has an opening for soil to fall out, the leachate belt is arranged in the conveying chamber, a sealing plate is arranged in the conveying chamber, and a waste liquid chamber is formed in the conveying chamber through the sealing plate.

[0020] As a further improvement of the technical solution, a waste chamber is provided at the bottom of the junction of the drainage belt and the soaking conveyor belt, and the drainage belt is composed of a material receiving section, a drainage section, a material discharge section and a return section, wherein:

[0021] The leachate section is located above the waste liquid chamber and is in a horizontal state;

[0022] The material receiving section is connected with the drainage section and extends to the bottom of the soaking conveyor belt to form an inclined surface. The soil on the inclined surface overcomes the static friction due to the action of gravity and rolls downward, and the waste chamber collects the rolled soil.

[0023] The soil on the discharge section falls back to the ground;

[0024] The return section is connected with the material receiving section.

[0025] The second object of the present invention is to provide a repair method for the soil treatment and environmental protection repair system, comprising the following method steps:

[0026] S1, the soil shoveling system collects soil during the driving process of the traveling system and transports it upwards;

[0027] S2, the soaking box receives the soil transported upward by the shoveling system, and forms a soaking space within the coverage of the soaking box, and then sprays the medicine with the help of the spray end arranged in the soaking space, and the medicine mixes with the soil in the soaking space;

[0028] S3, the conveyor belt group transports the soil in the soaked box to the heat flow output hood, forming a dehydration space within the coverage of the heat flow output hood, and the liquid medicine in the dehydration space is separated from the soil.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. In the soil treatment and environmental protection restoration system and restoration method, two independent spaces are used to complete the mixing of soil and liquid medicine and the separation of liquid medicine from soil. The two operations do not interfere with each other, which can ensure the full reaction between liquid medicine and soil without affecting the separation of liquid medicine, thus ensuring that the soil finally falling back to the ground does not contain liquid medicine and has a high level of restoration quality.

[0031] 2. In the soil treatment and environmental protection restoration system and restoration method, the sealed permeable conveyor belt can allow the drug solution and soil to stand still during the conveying stage to ensure that the drug solution and the soil fully react, and the conveying surface of the leachate belt is in a permeable state, so that the drug solution attached to the surface can flow out of the conveying surface of the leachate belt. At the same time, the hot air flow is used to evaporate the drug solution immersed in the soil, and the flow rate of the drug solution on the soil surface can be accelerated under the action of the air flow, thereby increasing the speed of the drug solution detachment and ensuring that the soil falling from the leachate belt is dry.

[0032] 3. In the soil treatment and environmental protection restoration system and restoration method, the material receiving section is an inclined surface, so under the action of gravity, the heavier soil will overcome the static friction and roll down along the material receiving section, and the rolled soil is collected through the waste chamber. The purpose is: because when the soil volume is too large, it is difficult for the medicine solution to penetrate into it, and it is not convenient for later use, especially in an environment where soil particle size is required for planting, so this part of the soil is eliminated through the material receiving section.

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0056] Furthermore, in the description of the present invention, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0057] The existing remediation methods do not extract the mixed liquid medicine, and the soil that falls back to the ground contains the liquid medicine, which will affect the final remediation quality. This is also the disadvantage of most mobile integrated soil remediation equipment. Once the liquid medicine is extracted quickly, it is difficult to ensure the process of soil and liquid medicine reaction, which will have a greater impact on the remediation quality. Therefore, many devices do not extract the liquid medicine.

[0058] To this end, the present invention provides a soil management and environmental protection restoration system, such as Figure 1 As shown, the device includes a traveling system 100, a soil shoveling system 200 and a soil remediation system 300 mounted on the traveling system 100. The soil shoveling system 200 shovels the soil on the ground along the path of the traveling system 100 and transports it upward. Figure 4As shown, the soil remediation system 300 is composed of a soaking box 310, a conveyor belt group 320 and a heat flow output cover 330. The soaking box 310 is used to receive the soil transported upward by the soil shoveling system 200. The spray end arranged in the soaking box 310 sprays the liquid medicine so that the liquid medicine is immersed in the soil. The heat flow output cover 330 is arranged on the side of the soaking box 310 outputting the soil, and the conveyor belt group 320 is arranged between the soaking box 310 and the heat flow output cover 330. The soil in the soaking box 310 is transported to the soil by the conveyor belt group 320. The soil is transported to the heat flow output cover 330. During the transportation process, the soaking box 310 and the heat flow output cover 330 separate the conveyor belt group 320 into two independent spaces (i.e., the soaking space and the dehydration space). The soaking space within the soaking box 310 allows the drug solution to fully contact with the soil, thereby improving the efficiency of the drug solution soaking the soil and ensuring that the drug solution can fully react with the soil. The dehydration space within the heat flow output cover 330 allows the drug solution to separate from the soil, and the dehydrated soil falls back to the ground with the help of the conveyor belt group 320.

[0059] Therefore, the mixing of soil and liquid medicine and the separation of liquid medicine from soil are completed through two independent spaces. The two operations do not interfere with each other, which can ensure the full reaction between liquid medicine and soil without affecting the separation of liquid medicine, thus ensuring that the soil finally falling back to the ground does not contain liquid medicine and has a high level of restoration quality.

[0060] Next, through Figure 2 and Figure 3 Shows the structures involved in shoveling out the soil.

[0061] Figure 2 The middle travel system 100 includes a travel base 110, a bracket 120 and a travel assembly 130. The bracket 120 is arranged in the travel direction of the travel base 110, and the specific travel power of the travel base 110 is realized by the travel assembly 130 arranged at the bottom thereof. The travel assembly 130 can be a tire or a track wheel set, and rotates under the drive of the engine. Then the travel assembly 130 carries the travel base 110 to move as the power output. At this time, the earth-moving system 200 is carried by the bracket 120. When the travel base 110 moves (that is, when driving), the earth-moving system 200 can move synchronously.

[0062] See also Figure 3As shown, the shoveling system 200 includes a side plate 210 and a shoveling belt 220 rotating on the periphery of the side plate 210. The shoveling belt 220 rotates around the periphery of the side plate 210 under the cooperation of a motor and a roller. The motor is installed on the side plate 210, and its output shaft is fixedly connected to the roller rotatably connected to the side plate 210, so that the motor drives the roller to drive the shoveling belt 220 to rotate. In order to achieve the effect of shoveling soil, a shovel body 230 is provided outside the shoveling belt 220 in this embodiment. When the shoveling system 200 moves synchronously with the traveling base 110, one end of the shoveling belt 220 contacts the ground, and then the rotating shovel body 230 is used to shovel out the soil and collect it, and then it moves with the shoveling belt 220 to transport the shoveled soil. When the shoveling belt 220 moves to the top, the soil collected in the shovel body 230 is poured into the soaking box 310 for subsequent operations.

[0063] It should be noted that in order to collect the shoveled soil, the shovel body 230 is configured as a bucket-shaped structure, so that a cavity for carrying soil can be formed after the shovel body 230 is connected to the shovel belt 220, and the end of the shovel body 230 that is shoveled into the ground is configured to be pointed to facilitate shoveling out the soil.

[0064] In addition, in order to be able to adjust the shoveling depth of the soil, the side plate 210 and the bracket 120 are specially connected in a sliding manner. The two are specifically connected by an electric slide rail, or other structures that can carry the side plate 210 to be telescopic on the bracket 120, and the shovel body 230 can be separated from the ground when not shoveling soil to avoid damage caused by contact with the ground.

[0065] When operating the travel system 100, the user needs to complete it in the control room 140, mainly performing the extension and retraction operations of the side panels 210, the rotation operations of the shovel belt 220 and the travel operations of the travel component 130. The control room 140 is set on the travel base 110, and in order to provide space for the installation of the soil remediation system 300, the control room 140 needs to be erected above the soil remediation system 300.

[0066] Next, through Figure 5-Figure 10 The specific structure of the soil remediation system 300 is disclosed.

[0067] Figure 5In the figure, a feeding port 310A for accessing the soil is arranged on the top of the impregnation box 310, and a impregnation chamber 310B connected to the feeding port 310A is arranged inside the impregnation box 310, that is to say, the connected soil directly enters the impregnation chamber 310B, at this time, one of the two independent spaces is formed through the impregnation chamber 310B: the impregnation space, a spray pipe 312 is arranged from the outside into the impregnation chamber 310B, a nozzle 313 is arranged on the spray pipe 312, and a liquid storage tank 311 is connected to the outer end of the spray pipe 312, and under the action of the negative pressure pump arranged in the liquid storage tank 311, the medicine liquid in the liquid storage tank 311 is sprayed out through the nozzle 313, so that the spray end is formed by the nozzle 313, and the sprayed medicine liquid is mixed with the soil in the impregnation space (i.e., the impregnation chamber 310B).

[0068] Figure 6 In the embodiment, the heat flow output cover 330 is located at the side of the infiltration chamber 310B where the soil is output, and the heat flow output cover 330 and the infiltration box 310 are both installed on the travel base 110. After installation, the heat flow output cover 330 is located on the conveying path of the conveyor belt group 320 to form a heat flow chamber 330A, so that one of the two independent spaces is formed through the heat flow chamber 330A: a dehydration space. In the dehydration space (i.e., the heat flow chamber 330A), there is a hot air flow passing through the conveyor belt group 320. The hot air flow heats the medicine and evaporates it quickly, thereby achieving the purpose of dehydrating the soil. Specifically:

[0069] The top of the heat flow output cover 330 is provided with a negative pressure device 332 for outputting air flow downward, and a heating plate 331 is provided in the heat flow cavity 330A. The heating plate 331 has an electric heating wire. Fig. 9 As shown, an air flow layer 330a and a heat flow layer 330b are formed under the isolation of the heating plate 331, and a heat flow cavity 330A is formed by the air flow layer 330a and the heat flow layer 330b. The air flow layer 330a is located above the heating plate 331, and the heat flow layer 330b is located below the heating plate 331. When working, the fan blades of the negative pressure device 332 rotate to form a downward airflow, and the airflow in the air flow layer 330a is a cold airflow. When the cold airflow passes through the heating plate 331 and flows into the heat flow layer 330b, it is heated by the electric heating wire and becomes a hot airflow. The hot airflow acts on the surface of the soil transported by the conveyor belt group 320, so that the medicine immersed in the soil is heated and evaporated, thereby realizing the separation of the medicine.

[0070] In this embodiment, the conveyor belt group 320 is composed of a soaking conveyor belt 321 and a draining belt 322. The soaking conveyor belt 321 and the draining belt 322 rotate independently, and the conveying surface of the soaking conveyor belt 321 is in a sealed state, and the conveying surface of the draining belt 322 is in a permeable state. The soaking conveyor belt 321 is used to convey the soil mixed with the liquid medicine in the soaking chamber 310B. The sealing setting allows the liquid medicine and the soil to stand still during the conveying stage of the soaking conveyor belt 321 to ensure that the liquid medicine and the soil fully react. The draining belt 322 is used for the soaking chamber 310B. The soil transported by the conveyor belt 321 is received and then transported to the hot flow chamber 330A, specifically moved in the hot flow layer 330b. During the process of the leachate belt 322 transporting the soil, since its surface is in a permeable state, the liquid medicine attached to the surface can flow out of the conveying surface of the leachate belt 322. At the same time, the hot air flow is used to evaporate the liquid medicine soaked in the soil. Moreover, under the action of the air flow, the flow speed of the liquid medicine on the soil surface can be accelerated, thereby increasing the speed of the liquid medicine detachment, ensuring that the soil falling from the leachate belt 322 is dry.

[0071] It should be noted that if Figure 2 As shown, a side frame 111 is provided on the travel base 110, preferably two side frames are provided, the soaking conveyor belt 321 and the drainage belt 322 are both installed between the two side frames 111, and the corresponding driving mechanism is installed on the side frame 111, and the through groove uses a roller and a motor to form a driving mechanism to drive the soaking conveyor belt 321 and the drainage belt 322 respectively, and a conveying chamber 110A is provided on the travel base 110, and the drainage belt 322 is arranged in the conveying chamber 110A. On the one hand, the bottom of the conveying chamber 110A has an opening for soil to fall out, and on the other hand, the conveying chamber 110A has a waste liquid chamber 110C ( Fig.12 ), the liquid medicine flowing out of the leachate belt 322 is recovered through the waste liquid chamber 110C.

[0072] Furthermore, in order to ensure that all the soil falls on the saturation conveyor belt 321, please refer to Figure 8 As shown, the bottom of the impregnation box 310 is provided with an access port 310C on the side where the feed port 310A is located, and an access port 310D is opened on the opposite side of the access port 310C. Then the impregnation conveyor belt 321 passes through the access port 310C from the outside and extends to the side where the access port 310D is located until it extends to a position where the soil can be transported to the leachate belt 322. The leachate belt 322 can be partially in the impregnation cavity 310B or completely separated from the impregnation cavity 310B.

[0073] It should be noted that, see Fig.12As shown, a sealing plate 112 is provided in the transport chamber 110A, and a waste liquid chamber 110C is formed in the transport chamber 110A through the sealing plate 112. That is, the waste liquid chamber 110C formed by the sealing plate 112 finally carries the separated liquid medicine.

[0074] The specific use principle of the above structure is disclosed here:

[0075] First, the traveling base 110 moves with the shovel system 200 under the action of power output of the bracket 120, and then one end of the shovel belt 220 contacts the ground, and the soil is shoveled out by the shovel body 230 and transported upward. When transported to the top, the soil carried by the shovel body 230 is poured into 210A and enters 210B through 210A. At this time, the falling soil spreads under the action of gravity, and at the same time, the nozzle 313 as the spray end sprays liquid medicine. At this time, the liquid medicine and the spread soil are mixed more fully, because the contact area between the spread soil and the liquid medicine is enlarged, so they can be mixed more fully, and then fall on the soaking conveyor belt 321;

[0076] At this time, the surface of the soaking conveyor belt 321 is sealed, so the liquid medicine will not flow down, but will be fully immersed in the soil. Moreover, the soil can be fully mixed with the liquid medicine before, which can prevent the problem of liquid medicine fault caused by soil superposition. Because when the liquid medicine and the soil are fully mixed, no matter how the soil is superimposed, there is liquid medicine in the superimposed space without fault, thereby ensuring the quality of liquid medicine soaking into the soil and ensuring that the liquid medicine can fully react with the soil.

[0077] As the soaking conveyor belt 321 is transported, the soil falls onto the leachate belt 322 at the end of the soaking conveyor belt 321, and then the soil is transported to the thermal flow layer 330b with the help of the leachate belt 322. During the transportation process, the liquid medicine will flow out of the conveying surface of the leachate belt 322, and then fall into the waste liquid chamber 110C. The liquid medicine is recovered through the waste liquid chamber 110C, and the liquid medicine immersed in the soil is evaporated by the hot air flow in the thermal flow layer 330b, so as to achieve the separation of the liquid medicine. Finally, the soil on the leachate belt 322 falls to the ground through the opening at the bottom of the conveying chamber 110A. At this time, the soil falling on the ground is in a dry state. On the one hand, the particle size of the soil is guaranteed to prevent the wet soil from agglomerating under the action of external pressure, and on the other hand, the liquid medicine is prevented from mixing into the ground.

[0078] Based on the above implementation, the following improvements are made:

[0079] like Fig.11As shown, a sieve plate 314 is provided in the soaking box 310 parallel to the spray pipe 312, the bottom of the sieve plate 314 is bent downward, and a plurality of diverter heads 3141 are provided at the bent end. The sieve plate 314 has a sieve mesh inside, and the soil is screened by the sieve mesh. Once screened, the finer particles of soil will quickly leave the sieve plate 314, while the coarser particles of soil cannot pass through the sieve mesh and remain on the sieve plate 314. In this way, the coarser particles of soil can be mixed with the medicine for a longer time, because the coarser particles of soil have a larger surface area, so they need to be in contact with the medicine for a longer time. However, the finer particles of soil have a relatively small density, so the medicine has poor fluidity. Therefore, the finer particles of soil on the soaking conveyor belt 321 can be divided into ridges through the obstruction of the diverter head 3141, so as to provide a channel for the circulation of the medicine, which can facilitate the medicine to be more fully immersed in the soil.

[0080] like Fig.12 As shown, a waste chamber 110B is provided at the bottom of the conveying chamber 110A where the leachate belt 322 and the soaking conveying belt 321 are connected, and a waste chamber 110B is provided in combination with the waste chamber 110B. Fig.10 As shown, the drain belt 322 is composed of a material receiving section 322a, a drain section 322b, a material discharge section 322c and a return section 322d. The drain section 322b is located above the waste liquid chamber 110C and is in a horizontal state. The material receiving section 322a is connected to the drain section 322b and extends to the bottom of the soaking conveyor belt 321 to receive soil. Since the material receiving section 322a is an inclined surface, under the action of gravity, the heavier soil will overcome the static friction and roll down along the material receiving section 322a. At this time, the rolled soil is collected through the waste chamber 110B. The purpose is: because when the soil volume is too large, it is difficult for the medicine solution to penetrate into it, and it is not convenient for later use, especially in an environment where planting requires soil particle size. Therefore, this part of the soil is eliminated through the receiving section 322a, and the soil on the discharge section 322c is the soil that falls back to the ground. The return section 322d is only connected to the receiving section 322a to form a cycle to ensure that the leachate belt 322 can circulate.

[0081] In addition, returning to Fig.12 Because liquid is recovered in the waste liquid chamber 110C, the liquid medicine is easy to splash out under the action of inertia, so a splash-proof layer 113 is provided on the top of the sealing plate 112, and a plurality of conical holes are opened on the splash-proof layer 113, and the plate body forming the conical holes is a flexible structure. Under the action of the hot air flow, the conical holes are in an open state, otherwise they are in a closed state to prevent the liquid medicine from splashing out.

[0082] Furthermore, a condenser tube can be provided in the sealing plate 112 to allow the evaporated liquid to release heat and then be converted into liquid and stored in the waste liquid chamber 110C. At the same time, it can also reduce the overall heat output of the device and avoid energy consumption caused by heat.

[0083] The present invention also provides a repair method for a soil treatment and environmental protection repair system, which comprises the following method steps:

[0084] S1, the soil shoveling system 200 collects soil during the traveling system 100 and transports it upward;

[0085] S2, the soaking box 310 receives the soil transported upward by the soil shoveling system 200, and forms a soaking space within the coverage of the soaking box 310, and then sprays the medicine with the help of the spray end provided in the soaking space, and the medicine mixes with the soil in the soaking space;

[0086] S3, the conveyor belt group 320 conveys the soil in the soaked box 310 to the heat flow output cover 330, and a dehydration space is formed within the coverage of the heat flow output cover 330, and the liquid medicine in the dehydration space is separated from the soil.

[0087] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
