Description

Technical Field

[0001] This invention belongs to the field of soil pollution remediation technology, specifically a device for uniformly applying soil pollution remediation agents for land treatment. Background Technology

[0002] Soil pollution refers to the phenomenon where pollutants generated by human activities enter the soil, accumulate to a certain level exceeding the soil's self-purification capacity, leading to the deterioration of the soil's physical, chemical, and biological properties, damaging its ecological functions, and consequently affecting the quality and safety of agricultural products and human health. It is characterized by its insidious nature, delayed effects, cumulative effect, and irreversibility, making its remediation far more difficult than that of air and water pollution. In the application process of soil remediation agents, spraying followed by tilling is the mainstream approach. In some scenarios, tilling followed by spraying is used. The core purpose of this process is to ensure sufficient contact between the agent and soil particles, preventing agent loss or localized accumulation. For soils with complex contamination or high-viscosity agents, a repeated process of tilling, spraying, and tilling is employed to further enhance the mixing of the agent with the soil and ensure remediation effectiveness.

[0003] In existing technologies, soil needs to be strictly layered and stacked during soil turning (topsoil and contaminated remediation soil should be separated). Backfilling should be done in the "original soil layer sequence" to avoid disrupting the soil structure. When removing the topsoil, it is usually done on a large area of ​​land, where all the topsoil is turned over, piled up and broken up. After applying chemicals to the bottom soil, the broken-up topsoil is backfilled. The whole process is time-consuming and labor-intensive. Therefore, improvements are needed to address the above problems. Summary of the Invention

A surface spraying mechanism is mounted on a fixed plate and is used to spray the agent into the crushing mechanism. A bottom spraying mechanism, which is mounted on a fixed plate and is used to spray the agent onto the bottom soil. An upward tilting mechanism is provided inside the crushing mechanism and is used to throw the surface soil that has been broken up inside the crushing mechanism upward. A dust suppression mechanism is located at the bottom of a fixed plate and is used to transport the dust generated by the shoveling mechanism and the crushing mechanism from the surface soil to the inside of the crushing mechanism to mix with the agent sprayed by the surface spraying mechanism.

[0006] Preferably, the shoveling mechanism includes a bucket, a baffle, and a hydraulic rod. The bucket is hinged to the bottom of a fixed plate, the baffle is symmetrically installed on both sides of the bucket, and the two ends of the hydraulic rod are hinged to the fixed plate and the baffle, respectively.

[0007] Preferably, the crushing mechanism includes a crushing box, crushing rollers, gears, and a drive motor. The crushing box is fixedly connected to the bottom of a fixed plate by a bracket. The crushing rollers are symmetrically rotatably connected to the opening at the top of the crushing box, and the crushing teeth on the surfaces of the two crushing rollers are interlaced. The gears are installed at both ends of the crushing rollers, and the gears on the two crushing rollers mesh. The drive motor is installed on the fixed plate and drives one of the crushing rollers.

[0008] Preferably, the surface spraying mechanism includes a first water pump, a first inlet pipe, a first drain pipe, a first connecting pipe, and a first nozzle. The first water pump is mounted on a fixed plate. The first inlet pipe and the first drain pipe are respectively connected to the inlet and outlet of the first water pump. The first connecting pipe is connected to the bottom of the first drain pipe. The first nozzle is equidistantly installed at the bottom of the first connecting pipe. The first connecting pipe and the first nozzle are located inside the crushing chamber.

[0009] Preferably, the bottom spraying mechanism includes a second water pump, a second inlet pipe, a second drain pipe, a second connecting pipe, and a second nozzle. The second water pump is installed on the top of the fixed plate. The second inlet pipe and the second drain pipe are respectively installed at the inlet and outlet of the second water pump. The second connecting pipe is installed at the bottom of the second drain pipe and fixed to the bottom of the crushing box by a bracket. The second nozzle is installed at equal intervals at the bottom of the second connecting pipe.

[0010] Preferably, the flipping mechanism includes a flip plate and a cam, both of which are rotatably connected inside the crushing box. The cam is located below the movable end of the flip plate and is connected to another crushing roller via a drive.

The removed topsoil is then broken up by a crushing mechanism. Simultaneously, a second water pump discharges the chemical agent through a second nozzle onto the surface of the underlying soil beneath the removed topsoil. The broken topsoil falls onto an upward-turning mechanism and is discharged through the discharge port of the crushing box. The chemical agent is sprayed directly after the topsoil is removed, and then the crushed topsoil is used to cover the chemical agent.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 7 As shown, the present invention provides a soil pollution remediation agent uniform application device for land remediation, including a fixing plate 100, with wheels 110 installed at the four corners of the bottom of the fixing plate 100, and further including: The storage tank 200 is mounted on the fixing plate 100 and is used to hold soil remediation agents; The soil-shoveling mechanism 300 is located at the bottom of the fixed plate 100 and is used to remove the surface soil. The crushing mechanism 400 is located at the bottom of the fixed plate 100 and is used to crush the surface soil turned over by the shovel mechanism 300. Surface spraying mechanism 500, which is mounted on fixed plate 100 and is used to spray the agent into the crushing mechanism 400. A bottom spraying mechanism 600 is mounted on a fixed plate 100 and is used to spray pesticides onto the bottom soil. The upward tilting mechanism 700 is located inside the crushing mechanism 400 and is used to throw the surface soil that has been broken up inside the crushing mechanism 400 upward. The dust suppression mechanism 800 is located at the bottom of the fixed plate 100 and is used to transport the dust generated by the shoveling mechanism 300 and the crushing mechanism 400 to the inside of the crushing mechanism 400 to mix with the agent sprayed by the surface spraying mechanism 500.

[0020] The above scheme is adopted as follows: the topsoil of the land is removed by the shoveling mechanism 300, and the removed topsoil is broken up by the crushing mechanism 400. The broken topsoil falls onto the turning mechanism 700 and is lifted up by the turning mechanism 700. When the topsoil is lifted up, the dust suppression mechanism 800 transports the dust generated by the shoveling mechanism 300 and the crushing mechanism 400 to the crushing mechanism 400. The surface spraying mechanism 500 sprays a small amount of agent to mix with the dust and the lifted topsoil. While achieving the dust suppression effect, it can also mix the agent with the topsoil. Since the agent spraying position of the surface spraying mechanism 500 is located in the middle area of ​​the turning mechanism 700, the agent mixed with dust increases in weight and falls quickly to mix with the lifted topsoil. It is further uniformly mixed as the turning mechanism 700 continues to lift it up.

[0021] like Figure 3 As shown, the earthmoving mechanism 300 includes a bucket 310, a baffle 320 and a hydraulic rod 330. The bucket 310 is hinged to the bottom of the fixed plate 100, the baffle 320 is symmetrically installed on both sides of the bucket 310, and the two ends of the hydraulic rod 330 are hinged to the fixed plate 100 and the baffle 320 respectively.

[0022] The above solution allows the baffle 320 to shield the soil scooped out by the bucket 310, preventing soil from falling. As the fixed plate 100 is driven by the drive device to move on the contaminated land, the topsoil accumulates on the bucket 310 and falls backward into the two sets of crushing rollers 420 for crushing. The design of the hydraulic rod 330 can also control the depth of scooping, making it more versatile.

[0023] like Figure 4 and Figure 5 As shown, the crushing mechanism 400 includes a crushing box 410, a crushing roller 420, a gear 430, and a drive motor 440. The crushing box 410 is fixedly connected to the bottom of the fixed plate 100 by a bracket. The crushing roller 420 is symmetrically rotatably connected to the opening at the top of the crushing box 410, and the crushing teeth on the surfaces of the two crushing rollers 420 are interlocked. The gear 430 is installed at both ends of the crushing roller 420, and the gears 430 on the two crushing rollers 420 mesh. The drive motor 440 is installed on the fixed plate 100 and drives one of the crushing rollers 420. The end of the crushing box 410 away from the bucket 310 is also provided with a discharge port for the surface soil crushed by the crushing roller 420 to be discharged.

[0024] The above scheme is adopted: the topsoil is crushed by two crushing rollers 420, and the gear 430 is set to make the two crushing rollers 420 rotate synchronously in opposite directions. The crushed topsoil falls on the overturning mechanism 700 and slides down with the inclined overturning mechanism 700. Finally, it is discharged through the discharge port on the crushing box 410 and falls on the excavated bottom soil.

[0025] like Figures 4 to 7 As shown, the surface spraying mechanism 500 includes a first water pump 510, a first inlet pipe 520, a first drain pipe 530, a first connecting pipe 540, and a first nozzle 550. The first water pump 510 is mounted on the fixed plate 100. The first inlet pipe 520 and the first drain pipe 530 are respectively connected to the inlet and outlet of the first water pump 510. The first connecting pipe 540 is connected to the bottom of the first drain pipe 530. The first nozzle 550 is equidistantly installed at the bottom of the first connecting pipe 540. The first connecting pipe 540 and the first nozzle 550 are located inside the crushing box 410. The upward tilting mechanism 700 includes a tilting plate 710 and a cam 720. Both the tilting plate 710 and the cam 720 are rotatably connected to the inside of the crushing box 410. The cam 720 is located below the movable end of the tilting plate 710. The cam 720 transmits power to another crushing roller 420. The dust collection mechanism 800 includes a fan 810, an air inlet pipe 820, a first collection chamber 830, a third connecting pipe 840, a second collection chamber 850, an exhaust pipe 860, and a limiting baffle 870. The fan 810 is installed at the bottom of the fixed plate 100. The air inlet pipe 820 and the exhaust pipe 860 are respectively installed at the air inlet end and the air outlet end of the fan 810. The first collection chamber 830 is connected to the air inlet pipe 820. The two ends of the third connecting pipe 840 are respectively connected to the first collection chamber 830 and the second collection chamber 850. The limiting baffle 870 is installed at the bottom of the exhaust pipe 860. The bottom of the exhaust pipe 860 is provided with an opening and the limiting baffle 870 is installed at both ends of the opening. The opening at the bottom of the exhaust pipe 860 is inclined and points downwards towards the first nozzle 550. The bottom of the first collection chamber 830 is directly above the crushing roller 420.

[0026] The above scheme employs the following method: the dust generated during the shoveling of soil by the bucket 310 is extracted through the second collection chamber 850, and the dust generated during the crushing of the topsoil is extracted through the first collection chamber 830. The extracted dust is then discharged into the crushing chamber 410 through the exhaust pipe 860, where it mixes with a small amount of reagent discharged from the first nozzle 550. At this point, the mixture of dust and reagent increases in weight and falls faster, mixing with the crushed topsoil lifted by the overturning mechanism 700, and is finally re-covered on the bottom soil. By extracting the dust, secondary pollution that may be caused by dust dispersion is prevented, thus improving the effect of soil pollution remediation. The limiting baffle 870 is inclined, pointing towards the reagent sprayed through the first nozzle 550, which allows for better mixing. Furthermore, the increased weight and faster falling speed of the mixture prevent it from being directly discharged into the crushing chamber 410.

[0027] like Figure 5 As shown in Figure 6, the bottom spraying mechanism 600 includes a second water pump 610, a second inlet pipe 620, a second drain pipe 630, a second connecting pipe 640, and a second nozzle 650. The second water pump 610 is installed on the top of the fixed plate 100. The second inlet pipe 620 and the second drain pipe 630 are respectively installed at the inlet and outlet of the second water pump 610. The second connecting pipe 640 is installed at the bottom of the second drain pipe 630 and fixed to the bottom of the crushing box 410 by a bracket. The second nozzle 650 is equidistantly installed at the bottom of the second connecting pipe 640.

[0028] The above-mentioned solution involves applying the agent to the surface of the bottom soil using a second nozzle 650 located below the bucket 310 and the crushing box 410. After the agent is applied to the bottom soil, it is directly covered by the crushed topsoil, reducing the risk of agent loss and volatilization, lowering the probability of secondary pollution, and improving the uniformity of the remediation effect.

[0029] Working principle and usage process of this invention: In use, the fixed plate 100 is driven by the drive device to move on the contaminated land. During movement, the bucket 310 is tilted by the hydraulic rod 330, increasing its inclination to remove the topsoil. Simultaneously, the drive motor 440, the first water pump 510, the second water pump 610, and the blower 810 are started. The drive motor 440 drives the crushing roller 420 to rotate and crush the topsoil removed by the bucket 310. The blower 810 extracts the dust generated by the bucket 310 during shoveling through the second collection bin 850 and discharges it through the first collection bin 850. Dust generated during the crushing of the topsoil is extracted and discharged into the crushing chamber 410 through the exhaust pipe 860. It mixes with a small amount of agent discharged from the first nozzle 550. At this time, the mixture of dust and agent increases in weight and falls faster. It mixes with the crushed topsoil lifted by the overturning mechanism 700. The second water pump 610 discharges most of the agent through the second nozzle 650 onto the bottom soil after the topsoil has been removed. Finally, the mixture of a small amount of agent, dust and crushed topsoil is re-covered on the bottom soil.
