Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, in particular to a contaminated soil remediation device. Background Art

[0002] With the continuous acceleration of the industrialization process, the irrational exploitation of mineral resources, machine smelting emissions, long-term sewage irrigation and sludge application to the soil, atmospheric deposition caused by human activities, and the application of chemical fertilizers and pesticides have caused serious soil pollution, loss of fertility, dryness and water shortage. Therefore, soil repair and regeneration are particularly important. The existing repair mainly breaks the soil and then sprays chemical agents on the soil. After the soil absorbs them, it gradually restores its normal function.

[0003] However, when crushing the soil, traditional equipment is not convenient to adjust the position of the blade according to needs. Multiple bolts need to be disassembled and assembled during adjustment, which is very cumbersome to operate. In addition, the crushed soil adheres to the equipment cover and is difficult to clean, thereby causing wear on the tool and affecting the crushing effect. At the same time, the sprayed agent is sprayed directly on the surface of the soil layer, and the internal soil cannot absorb it, resulting in uneven absorption of the agent. In addition, the nozzle for spraying the agent lacks protective measures, which may cause blockage and affect the subsequent spraying of the drug. Summary of the Invention

DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0041] Specifically, such as Figure 1 、 Figure 2 and Figure 3As shown, the crushing mechanism 2 includes a mechanical arm 201, which is rotatably connected to the center line of one side of the mounting plate 1. Telescopic rods 207 are rotatably connected to the centers of both sides of the mechanical arm 201. One end of the two telescopic rods 207 is rotatably connected to the side walls of the mounting plate 1. One end of the mechanical arm 201 is rotatably connected to a rotating shaft 204. Both ends of the rotating shaft 204 extend to the outside of both sides of the mechanical arm 201. Both ends of the rotating shaft 204 are respectively installed with multiple equidistantly distributed rotary blades 202. The two ends of the interior of the mechanical arm 201 are rotatably connected to sprockets 205. The two sprockets 205 are connected by a chain 206. The rotating shaft 204 is connected to one of the sprockets 205, and the rotating shaft 204 and the rotary tiller 202 are connected through the installation of the mechanical arm 201. The angle of the mechanical arm 201 is adjusted by driving and controlling the two telescopic rods 207, so that the rotary tiller 202 can be brought into contact with the ground and crushed when working. When not working, the mechanical arm 201 rises to lift the rotary tiller 202, and the sprocket 205 is driven by external equipment, so that the rotating shaft 204 and the rotary tiller 202 are controlled to rotate with the cooperation of the chain 206, which is beneficial to crushing and loosening the soil.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, the two side walls at one end of the robotic arm 201 are detachably connected with symmetrical protective covers 203, and the protective covers 203 are located on the outside of the rotary blade 202. The top side of the protective cover 203 is a polygonal structure. By installing the protective cover 203, the rotary blade 202 is shielded and protected, which plays a role of safety protection and can also prevent soil from splashing.

[0043] Specifically, such as Figure 2 、 Figure 6 and Figure 7As shown, the cleaning mechanism 4 includes a movable groove 402, and the two protective covers 203 are respectively provided with a movable groove 402 at the inner midline of the top. A screw 401 is rotatably connected inside the movable groove 402, and one end of the screw 401 extends to the outside of the protective cover 203. A slider 405 is threadedly connected to the screw 401, and the slider 405 is slidably connected to the inside of the movable groove 402. The inner wall of the two protective covers 203 is slidably connected with a scraper 404, and the bottom of the slider 405 is fixedly connected to the center of the top side of the scraper 404. One side of the scraper 404 is a trapezoidal structure. The movable groove 402 slides inside. A dust cover 403 is connected, and the opening of the movable groove 402 facilitates the installation of the slider 405 and the screw 401. The movement of the slider 405 is controlled by driving the screw 401. The connection between the scraper 404 and the slider 405 enables the slider 405 to drive the slide plate to move on the inner wall of the protective cover 203, thereby scraping off the soil attached to the inner wall of the protective cover 203, preventing the rotary tillage blade 202 from being worn and affecting the subsequent crushing work. The installation of the dust cover 403 facilitates the shielding and protection of the screw 401.

[0044] Specifically, such as Figure 1 、 Figure 2 and Figure 9 As shown, the spraying mechanism 5 includes a storage box 501, and the storage boxes 501 are respectively installed on the top of the two protective covers 203. The top of the storage box 501 is threadedly connected with a top cover 502, and two symmetrical delivery pipes 503 are installed at the bottom of the storage box 501. Spray pipes 505 are installed on both sides of the protective cover 203. The side walls of the nozzle 505 are provided with a plurality of equally distributed guide grooves 506. One end of the delivery pipe 503 is connected to the center of the nozzle 505. The installation of the storage box 501 is conducive to the storage of liquid medicine. By opening the top cover 502, it is convenient to add liquid medicine to the inside of the storage box 501. The liquid medicine enters the inside of the nozzle 505 through the delivery pipe 503 and is discharged through the plurality of guide grooves 506, which is conducive to adding liquid medicine to the crushed soil, thereby changing the activity of the soil and facilitating subsequent planting work.

[0045] Specifically, such as Figure 2 As shown, the protective cover 203 is detachably connected to mounting bases 504 on both sides, and the mounting bases 504 are of a "concave"-shaped structure. The two ends of the nozzle 505 are rotatably connected to the two ends of the mounting bases 504. The installation of the mounting bases 504 facilitates the connection of the nozzle 505, and the angle of the nozzle 505 can be rotated to adjust the spraying position as needed, thereby improving the soil remediation effect.

[0046] Specifically, such as Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the paving mechanism 3 includes a fixed plate 301, and the fixed plate 301 is detachably connected to the robotic arm 201. A connecting plate 302 is installed at the bottom of one end of the fixed plate 301. The connecting plate 302 is a "convex" shaped structure. A plurality of equidistantly distributed sharp teeth 304 are vertically connected to the bottom of the connecting plate 302. The installation of the fixed plate 301 facilitates the connection of the connecting plate 302. The installation of a plurality of sharp teeth 304 allows the crushed soil to be leveled, which is beneficial for subsequent planting work and can cover the sprayed medicine to reduce the evaporation and loss of medicine efficacy of the medicine.

[0047] Specifically, such as Figure 4 and Figure 5 As shown, the top of the connecting plate 302 is rotatably connected to the bottom of one end of the fixed plate 301, and a plurality of telescopic springs 305 are connected between the bottom of one end of the fixed plate 301 and the side wall of the connecting plate 302. The two ends of the connecting plate 302 are respectively fixedly connected with a reinforcing plate 303, and the reinforcing plate 303 and the connecting plate 302 are connected at a 45-degree angle. Through the installation of the telescopic springs 305, the connecting plate 302 and the fixed plate 301 have telescopic properties, so that the tines 304 can swing according to the force when they are leveled with the ground, thereby preventing damage to the tines 304 and making the operation more flexible. Through the installation of the reinforcing plate 303, the connecting plate 302 has good stability and will not swing or deform.

[0048] Specifically, such as Figure 2 、 Figure 8 and Figure 11As shown, the pressurizing mechanism 7 includes a fixing seat 701, and one end of the top of the two protective covers 203 is respectively installed with a fixing seat 701, and a telescopic airbag 706 is slidably connected inside the fixing seat 701. An air inlet pipe 704 is installed on the top of the telescopic airbag 706, and an exhaust pipe 703 is vertically connected to the bottom of the air inlet pipe 704. A one-way valve 705 is respectively installed on the exhaust pipe 703 and the air inlet pipe 704. The exhaust pipe 703 is located at the bottom of the one-way valve 705. One end of the exhaust pipe 703 and the air inlet pipe 704 extends to the outside of the fixing seat 701 respectively, and one end of the exhaust pipe 703 extends to the outside of the fixing seat 701. To the inside of the storage box 501, by driving the telescopic airbag 706, the gas inside the telescopic airbag 706 enters the inside of the air inlet pipe 704, and under the obstruction of the one-way valve 705, the gas enters the inside of the exhaust pipe 703, and with the cooperation of the one-way valve 705, the gas is unidirectionally injected into the inside of the storage box 501 to pressurize it, so that the medicine is sprayed out. When the telescopic airbag 706 is reset, external air enters the telescopic airbag 706 through the air inlet pipe 704 and the one-way valve 705, which is convenient for subsequent injection into the inside of the storage box 501 for pressurization, thereby realizing continuous spraying of the medicine.

[0049] Specifically, such as Figure 2 As shown, a pressure relief valve 702 is installed on the inner side of the top of the top cover 502. The top of the pressure relief valve 702 extends to the outside of the top cover 502, and the bottom of the pressure relief valve 702 extends to the inside of the storage box 501. The installation of the pressure relief valve 702 facilitates pressure relief for the storage box 501, preventing damage caused by excessive internal pressure of the storage box 501.

[0050] Specifically, such as Figure 8 、 Figure 11 and Figure 12As shown, the control mechanism 8 includes a connecting seat 801, and the inner walls of the two protective covers 203 are respectively installed with connecting seats 801, the top of the connecting seat 801 extends to the outside of the top of the protective cover 203, and the inside of the two connecting seats 801 are respectively installed with a push rod 803, and the push rod 803 is slidably connected to the inside of the connecting seat 801 through the conflicting spring 804, and the top of the push rod 803 extends to the outside of the connecting seat 801, and the top of the push rod 803 extends to the inside of the fixed seat 701 and conflicts with the bottom of the telescopic airbag 706, and the push rod 803 is slidably connected to the inside of the fixed seat 701, and a plurality of convex blocks 802 distributed in an annular shape and equidistantly are fixedly connected to the outside of the two ends of the rotating shaft 204, and the convex blocks 802 are hemispherical structures. The protrusion 802 is located at the bottom of the connecting seat 801, and the bottom of the top rod 803 extends to the outside of the connecting seat 801 and contacts the protrusion 802. The installation of the connecting seat 801 facilitates the connection of the top rod 803. With the cooperation of the contact spring 804, the top rod 803 is contacted and slides down, so that the telescopic airbag 706 is in a reset state. When the rotating shaft 204 rotates, the multiple protrusions 802 on the rotating shaft 204 contact the top rod 803 respectively, so that the top rod 803 is free from the elastic force of the contact spring 804 and moves, so that the top rod 803 repeatedly contacts the telescopic airbag 706, which is beneficial for the telescopic airbag 706 to generate gas and inject it into the interior of the storage box 501.

[0051] Specifically, such as Figure 12 As shown, a top block 805 is installed at the bottom of the top rod 803, and the top block 805 is a trapezoidal structure. The top block 805 is slidably connected to the inside of the connecting seat 801, and a pressure wheel 806 is rotatably connected to the bottom of the top block 805. The pressure wheel 806 contacts the protrusion 802. The installation of the top block 805 facilitates the connection of the pressure wheel 806, and the rotation of the protrusion 802 achieves smooth contact with the pressure wheel 806, thereby reducing the wear caused by the conflict.

[0052] Specifically, such as Figure 9 and Figure 10As shown, the protective mechanism 6 includes a sleeve 601, and a plurality of sleeves 601 are installed on the side walls of the nozzles 505 at equal distances. The sleeve 601 is a cylindrical "convex"-shaped structure with one end open. One end of the sleeve 601 extends to the outside of the nozzle 505, and the other end of the sleeve 601 extends to one end of the guide groove 506. The diameter of the guide groove 506 is smaller than the diameter of one end of the sleeve 601. A compression spring 602 is connected to the outside of the sleeve 601. The sleeve 601 is slidably connected to the side wall of the nozzle 505 through the compression spring 602. The side wall of the sleeve 601 is provided with a plurality of spray holes 603. , causing the sleeve 601 to shrink inside the side wall of the nozzle 505, so that the spray holes 603 on the sleeve 601 are blocked, and the liquid medicine cannot be sprayed out. When the pressure of the liquid medicine inside the nozzle 505 reaches a certain level, the liquid medicine inside the sleeve 601 drives the sleeve 601 to get rid of the elastic force of the compression spring 602 and slide. After the sleeve 601 slides out of the nozzle 505, the spray holes 603 leak out, so that the liquid medicine is sprayed out from the multiple spray holes 603. When the liquid medicine has no pressure, the sleeve 601 is resisted and contracted by the compression spring 602, thereby hiding and protecting the spray holes 603 and preventing sand and gravel from clogging the spray holes 603.

[0053] Specifically, such as Figure 9 As shown, a plurality of equally spaced rubber sleeves 604 are fixedly connected to the inner side wall of the nozzle 505, and the bottoms of the plurality of sliding sleeves 601 are slidably connected to the inner side of the rubber sleeves 604. The installation of the rubber sleeves 604 facilitates wrapping the outer side of the sliding sleeves 601, thereby achieving blocking and sealing of the spray hole 603 to prevent the liquid medicine from overflowing.

[0054] When the present invention is in use, the mounting plate 1 is first detachably connected to the tractor equipment, and then the mechanical arm 201 is installed to connect the rotating shaft 204 and the rotary blade 202. The two telescopic rods 207 are driven and controlled to adjust the angle of the mechanical arm 201, so that the rotary blade 202 can be brought into contact with the ground for crushing when working. When not working, the mechanical arm 201 rises to lift the rotary blade 202, and the sprocket 205 is driven by an external device, so that the rotating shaft 204 and the rotary blade 202 are controlled to rotate with the cooperation of the chain 206, which is conducive to crushing and loosening the soil. The protective cover 203 is installed to shield and protect the rotary blade 202, which plays a role of safety protection and can also prevent soil from splashing. The installation of the plate 301 is conducive to the connection with the connecting plate 302. The installation of multiple sharp teeth 304 can make the crushed soil leveled, which is conducive to subsequent planting work and can cover the sprayed medicine to reduce the evaporation and loss of medicine effect of the medicine. The installation of the telescopic spring 305 makes the connecting plate 302 and the fixed plate 301 elastic, so that the sharp teeth 304 can swing according to the force when they are leveled with the ground, preventing damage to the sharp teeth 304 and making the operation more flexible. The installation of the reinforcement plate 303 makes the connecting plate 302 stable and will not swing or deform. The opening of the movable groove 402 is conducive to the installation of the slider 405 and the screw 401. The slider 405 can be controlled by driving the screw 401 to achieve 05 movement control, through the connection between the scraper 404 and the slider 405, the slider 405 drives the slide plate to move on the inner wall of the protective cover 203, and then scrapes off the soil attached to the inner wall of the protective cover 203, preventing the wear of the rotary blade 202 and affecting the subsequent crushing work. The installation of the storage box 501 is conducive to the storage of liquid medicine. By opening the top cover 502, it is convenient to add liquid medicine to the storage box 501. The liquid medicine enters the nozzle 505 through the delivery pipe 503 and is discharged through multiple guide grooves 506, which is conducive to adding liquid medicine to the crushed soil, thereby changing the activity of the soil and facilitating subsequent planting work. The installation of the mounting seat 504 is conducive to the connection of the nozzle 505 and the rotation angle of the nozzle 505. The spraying position can be adjusted as needed, thereby improving the soil remediation effect. The sleeve 601 is retracted inside the side wall of the nozzle 505 under the resistance of the compression spring 602, so that the spray hole 603 on the sleeve 601 is blocked and the liquid medicine cannot be sprayed out. When the liquid medicine pressure inside the nozzle 505 reaches a certain level, the liquid medicine inside the sleeve 601 drives the sleeve 601 to get rid of the elastic force of the compression spring 602 and slide. After the sleeve 601 slides out of the nozzle 505, the spray hole 603 leaks out, so that the liquid medicine is sprayed from multiple spray holes 603. When the liquid medicine has no pressure, the sleeve 601 is resisted and retracted by the compression spring 602, thereby hiding the spray hole 603 and preventing sand and gravel from clogging the spray hole 603. The installation of the rubber sleeve 604 is conducive to wrapping the outer side of the sleeve 601.The nozzle hole 603 is blocked and sealed to prevent the liquid from overflowing. The installation of the connecting seat 801 is conducive to the connection of the push rod 803. With the cooperation of the resistance spring 804, the push rod 803 is resisted and slides down, so that the telescopic airbag 706 is in a reset state. When the rotating shaft 204 rotates, the multiple protrusions 802 on the rotating shaft 204 respectively resist the push rod 803, so that the push rod 803 is free from the elastic force of the resistance spring 804 and moves, so that the push rod 803 repeatedly resists the telescopic airbag 706, which is conducive to the telescopic airbag 706 generating gas and injecting it into the storage box 501. The installation of the top block 805 is conducive to the connection of the pressure wheel 806. The rotation of the protrusion 802 realizes a smooth pressure wheel 80 6, thereby reducing wear caused by the conflict. By driving the telescopic airbag 706, the gas inside the telescopic airbag 706 enters the interior of the air inlet pipe 704. Under the obstruction of the one-way valve 705, the gas enters the interior of the exhaust pipe 703. With the cooperation of the one-way valve 705, the gas is injected into the storage box 501 in a one-way direction to increase the pressure, thereby spraying the liquid medicine. When the telescopic airbag 706 is reset, external air enters the telescopic airbag 706 through the air inlet pipe 704 and the one-way valve 705, making it convenient to inject the internal pressure of the storage box 501 again and realize the continuous spraying of the liquid medicine. The installation of the pressure relief valve 702 facilitates the pressure relief of the storage box 501, preventing the storage box 501 from being damaged due to excessive internal pressure.
