Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, and more specifically to a soil remediation device based on agricultural resources and the environment. Background Technology

[0002] Currently, soil remediation devices based on agricultural resources and the environment are developing rapidly and are diverse in type. In terms of physical remediation devices, soil electrodynamic remediation devices utilize electric fields to direct pollutants in the soil for centralized treatment, suitable for heavy metal pollution remediation; soil leaching devices inject leaching solution to desorb pollutants from soil particles and discharge them with the solution, showing good results for soil contaminated with pesticides and heavy metals; in chemical remediation devices, chemical oxidation-reduction devices add chemical oxidants or reducing agents to the soil to change the chemical properties of pollutants, reducing their toxicity or transforming them into easily treatable forms, commonly used for organically contaminated soil remediation; bioremediation devices are also attracting attention, such as bioventilation devices, which introduce air into the soil to provide oxygen for aerobic microorganisms, promoting their decomposition and metabolism of pollutants; phytoremediation devices utilize hyperaccumulating plants to absorb and transform pollutants in the soil to achieve ecological restoration, with low cost and environmental friendliness, but the remediation cycle is relatively long.

[0003] Chinese patent publication number CN118719789A discloses a soil remediation device, comprising: a housing with a vertical partition along its length dividing the upper space into a front cavity and a rear cavity; a conveyor belt horizontally positioned within the front cavity along the length of the housing, with a support plate below the upper belt; a separating roller horizontally positioned above the conveyor belt, the end of the separating roller near the side wall of the housing being closed and the end near the partition being open, the linear velocity direction of the lowest end of the separating roller being the same as the forward direction of the conveyor belt, to squeeze stones adhering to the conveyor belt and force the soil on the surface of the stones into a steel cylinder; a scraper extending into the open end of the separating roller to scrape the soil inside the steel cylinder; and a mixing cylinder positioned below the open end of the separating roller to receive the soil scraped from the steel cylinder. This invention disperses soil while simultaneously separating stones, allowing the remediation agent to be effectively utilized in the soil.

[0004] Currently, soil remediation devices based on agricultural resources and the environment generally use liquid spraying for remediation. This involves spraying the liquid onto the surface of contaminated soil to remediate it. However, this method only allows the surface layer of contaminated soil to absorb the remediation liquid and cannot further remediate the underlying soil, thus affecting the remediation effect. In addition, multiple chemicals are not required when using them, and sometimes they need to be mixed to achieve the best results. Some chemicals need to be mixed before spraying, otherwise their efficacy will be affected. Soil remediation devices based on agricultural resources and the environment cannot mix chemicals as needed to prevent waste from unused mixtures. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a soil remediation device based on agricultural resources and environment to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: a soil remediation device based on agricultural resources and environment, including a supporting shell, a shovel trough assembly slidably connected inside the supporting shell, a discharge switch assembly installed on one side of the shovel trough assembly, one end of the shovel trough assembly connected to a mixing assembly, a water conveying assembly movably connected above the mixing assembly, and a chemical tank fixedly connected above the water conveying assembly. The shovel assembly includes a hydraulic cylinder, the outer shell of the hydraulic cylinder is fixedly connected to the supporting outer shell, one end of the piston rod of the hydraulic cylinder is fixedly connected to a push rod, the upper part of the push rod is fixedly connected to a limit block, and the lower end of the push rod is fixedly connected to a shovel head. The discharge switch assembly includes an L-shaped plate, the vertical plate of the L-shaped plate is slidably connected to the outer shell of the shovel head, and an array of several springs are installed between the horizontal plate of the L-shaped plate and the shovel head.

The spring, the telescopic protective tube and the shovel head are located in the space enclosed by the L-shaped plate, the telescopic protective plate and the shovel head. The stirring assembly includes a second motor, and the shaft of the second motor is fixedly connected to a stirring fan. The stirring fan is located inside the stirring shell. The upper part of the stirring shell is connected to a water supply assembly. A hose is provided on one side of the stirring shell and is connected to a material supply hole. The stirring shell is connected to a water supply shell through a water supply pipe. Furthermore, a power assembly is movably connected below the water delivery assembly, and the medicine tank is located on top of the supporting shell.

[0007] Furthermore, the supporting shell includes a vehicle shell, with wheels movably connected to the bottom of the vehicle shell, and an inclined guide block fixedly connected inside the vehicle shell, and the push rod is slidably connected to the inclined guide block.

[0008] Furthermore, the shovel head includes a shovel body, which is conical and hollow inside. One side wall of the shovel body is provided with a plurality of through-array discharge holes. A stop block is fixedly connected to the top side of the shovel body, and two guide grooves are fixedly connected to the bottom of the stop block. An L-shaped vertical plate is slidably connected between the guide grooves. A material conveying hole is provided at the top of the shovel body, and the material conveying hole is connected to the stirring assembly. The area occupied by the shovel body is smaller than the size of the L-shaped vertical plate, and the L-shaped plate seals and shields the shovel body.

[0009] Furthermore, the power assembly includes a first motor, a drive wheel fixedly connected to the shaft of the first motor, a housing of the first motor fixedly connected to the inner wall of the vehicle body, and a first driven wheel, a second driven wheel, and a third driven wheel meshing with the outer side of the drive wheel. A rotating shaft is fixedly connected to the center of each of the first driven wheel, the second driven wheel, and the third driven wheel.

[0010] Furthermore, the hose is made of nitrile rubber.

[0011] Furthermore, the stirring fan includes a connecting ring, with multiple fan blades arranged in a circular array on the outer side of the connecting ring, and grooves provided on the inner side of the fan blades.

[0012] Furthermore, the water conveying assembly includes an impeller, the center of which is fixedly connected to a rotating shaft. A water conveying shell is provided on the outer side of the impeller, and a communication port is provided on the top of the water conveying shell, which is connected to the medicine tank.

[0013] The technical effects and advantages of this invention are as follows: 1. This invention uses a grooving assembly to form trenches deep into the soil. During the trenching process, a discharge switch assembly is used to control the precise flow of the agent into the trench. This method breaks through the limitation of traditional spraying, which only acts on the surface soil, and allows the remediation solution to act directly on the bottom soil, effectively increasing the absorption of the solution by the bottom soil and significantly enhancing the overall remediation effect of contaminated soil.

[0014] 2. The present invention is equipped with a power component to drive a water conveying component to extract chemicals from different chemical tanks.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The soil remediation device based on agricultural resources and environment involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figure 2 and Figure 3 The present invention provides a soil remediation device based on agricultural resources and environment, including a supporting shell 1, a shovel trough assembly 3 slidably connected inside the supporting shell 1, and a discharge switch assembly 4 installed on one side of the shovel trough assembly 3; The shovel assembly 3 includes a hydraulic cylinder 301. The outer shell of the hydraulic cylinder 301 is fixedly connected to the supporting outer shell 1. One end of the piston rod of the hydraulic cylinder 301 is fixedly connected to a push rod 302. The upper part of the push rod 302 is fixedly connected to a limit block 303. The lower end of the push rod 302 is fixedly connected to a shovel head 304. The discharge switch assembly 4 includes an L-shaped plate 401. The vertical plate of the L-shaped plate 401 is slidably connected to the outer shell of the shovel head 304. An array of several springs 402 is installed between the horizontal plate of the L-shaped plate 401 and the shovel head 304. A telescopic protective tube 403 is installed on the outside of the springs 402. A telescopic protective plate 404 is provided on the outside of the telescopic protective tube 403. The springs 402 and the telescopic protective tube 403 are located in the space enclosed by the L-shaped plate 401, the telescopic protective plate 404 and the shovel head 304.

[0019] In this embodiment, it should be specifically noted that: the hydraulic cylinder 301 is connected to an external oil tank, and the oil tank controls the inflow and outflow of hydraulic oil inside the hydraulic cylinder 301.

[0020] Reference Figure 1 and Figure 2 One end of the shovel assembly 3 is connected to the mixing assembly 6. A water supply assembly 7 is movably connected above the mixing assembly 6. A power assembly 5 is movably connected below the water supply assembly 7. A medicine tank 2 is fixedly connected above the water supply assembly 7. The medicine tank 2 is located on the top of the supporting shell 1. The supporting shell 1 includes a vehicle shell 101. A wheel 103 is movably connected to the bottom of the vehicle shell 101. An inclined guide block 102 is fixedly connected inside the vehicle shell 101. The push rod 302 is slidably connected to the inclined guide block 102.

[0021] In this embodiment, it should be specifically noted that the wheel 103 can only be started when the grooving action is completed and the medicine enters the trough smoothly, so that the device can move forward a certain distance before the grooving action is performed again.

[0022] Reference Figure 3 and Figure 5 The shovel head 304 includes a shovel body 3041, which is conical and hollow inside. One side wall of the shovel body 3041 is provided with multiple arrays of discharge holes 3042. A stop block 3044 is fixedly connected to the top side of the shovel body 3041. Two guide grooves 3043 are fixedly connected to the bottom of the stop block 3044. The vertical plate of the L-shaped plate 401 is slidably connected between the guide grooves 3043. A material conveying hole 3045 is provided at the top of the shovel body 3041. The material conveying hole 3045 is connected to the stirring assembly 6.

[0023] In this embodiment, it should be specifically noted that the area occupied by the shovel body 3041 is smaller than the vertical plate size of the L-shaped plate 401, which facilitates the L-shaped plate 401 to seal and cover the shovel body 3041.

[0024] Reference Figure 2 and Figure 4The power assembly 5 includes a first motor 501, a drive wheel 502 fixedly connected to the shaft of the first motor 501, a housing of the first motor 501 fixedly connected to the inner wall of the vehicle body 101, a first driven wheel 503, a second driven wheel 504, and a third driven wheel 505 meshing with the outer side of the drive wheel 502, and a rotating shaft 506 fixedly connected to the center of the first driven wheel 503, the second driven wheel 504, and the third driven wheel 505 respectively.

[0025] In this embodiment, it should be specifically noted that the ratio of the number of teeth of the first driven wheel 503, the second driven wheel 504, and the third driven wheel 505 is the mixing ratio of the corresponding agents.

[0026] Reference Figure 2 and Figure 4 The stirring assembly 6 includes a second motor 604, the shaft of which is fixedly connected to a stirring fan 602. The stirring fan 602 is located inside the stirring housing 601. The upper part of the stirring housing 601 is connected to the water supply assembly 7. A hose 603 is provided on one side of the stirring housing 601, and the hose 603 is connected to the material supply hole 3045.

[0027] In this embodiment, it should be specifically noted that the preferred hose 603 is located at the bottom of the stirring shell 601.

[0028] Reference Figure 4 and Figure 6 The stirring fan 602 includes a connecting ring 6021, and a plurality of fan blades 6022 are arranged in a circular array on the outer side of the connecting ring 6021. The inner side of the fan blades 6022 is provided with a groove 6023.

[0029] In this embodiment, it should be specifically noted that the groove 6023 causes the stirring fan 602 to rotate and generate vortices, which makes the various agents mix more thoroughly.

[0030] Reference Figure 2 and Figure 4 The water conveying assembly 7 includes an impeller 701, the center of which is fixedly connected to the rotating shaft 506. A water conveying shell 702 is provided on the outer side of the impeller 701. A water conveying pipe 703 is provided on one side of the water conveying shell 702. The water conveying pipe 703 is connected to the stirring shell 601. A connecting port 704 is provided on the top of the water conveying shell 702. The connecting port 704 is connected to the reagent tank 2.

[0031] In this embodiment, it should be specifically noted that when the impeller 701 extracts different agents from different agent tanks 2 and pumps them into the mixing shell 601 through the water pipe 703, the impeller 701 may rotate at different speeds due to the different number of teeth of the first driven wheel 503, the second driven wheel 504, and the third driven wheel 505. Thus, the pumping speed of the impeller 701 may be different when it rotates.

[0032] The specific steps are as follows: First, the entire device is placed on the soil to be repaired. The hydraulic cylinder 301 is activated, pushing the push rod 302, the limit block 303, and the shovel head 304 downwards at an angle. When the shovel body 3041 contacts the soil, it continuously breaks up the soil, forming an oblique trench. This trench can only be entered by the shovel head 304. When the soil comes into contact with the descending L-shaped plate 401, there will be resistance, while the shovel head 304 continues to descend. Thus, the surface of the L-shaped plate 401, in contact with the soil, will press against it, causing the L-shaped plate 401 to move upwards under the guidance of the guide groove 3043. The L-shaped plate 401 then compresses the telescopic protective tube 403 and the telescopic protective plate 404, causing them to retract. As the spring 402 compresses and deforms, the L-shaped plate 401 gradually exposes the discharge hole 3042 during its ascent. The medicine inside the shovel body 3041 flows out and into the trench along the tip of the shovel body 3041. When the limiting block 303 descends to contact the inclined guide block 102, the piston rod of the hydraulic cylinder 301 retracts, driving the shovel head 304 to rise. During the ascent, the L-shaped plate 401 gradually separates from the soil under the elastic force of the spring 402 and covers the discharge hole 3042 to prevent the medicine from continuing to flow out. The wheel 103 is activated, and the wheel 103 drives the device to move slowly, moving the shovel trench assembly 3 to the next trenching and medicine delivery location. When the dosage of medicine inside the shovel body 3041 is found to be insufficient, the first motor 501 is started. The first motor 501 drives the drive wheel 502 to rotate, which in turn drives the first driven wheel 503, the second driven wheel 504, and the third driven wheel 505 meshing with it to rotate. The first driven wheel 503, the second driven wheel 504, and the third driven wheel 505 drive the rotating shaft 506 and the impeller 701 fixedly connected to them to rotate. The impeller 701 draws different medicines from different medicine tanks 2 and pumps them into the mixing shell 601 through the water pipe 703. Due to the insufficient dosage of medicines inside the first driven wheel 503, the second driven wheel 504, and the third driven wheel 505, the first driven wheel 503, the second driven wheel 504, and the third driven wheel 505 drive the rotating shaft 506 and the impeller 701 to rotate. The different number of teeth on the driven wheel 504 and the third driven wheel 505 may result in different rotational speeds of the impeller 701, leading to different pumping rates. This allows for different mixing ratios of the three chemicals, satisfying the requirement for varying mixing ratios during chemical mixing. Once the different chemicals enter the mixing shell 601, the second motor 604 is started, driving the mixing fan 602 to rotate. The rotation of the mixing fan 602 accelerates the mixing of the various chemicals. After the chemicals are mixed, the hose 603 is opened, and the mixed chemicals enter the shovel body 3041 through the hose 603.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
