Description

Technical Field

[0001] This invention belongs to the field of soil remediation technology, and specifically relates to an intelligent remediation device for grassland soil pollution. Background Technology

[0002] The remediation of contaminated grassland soil is usually carried out through three methods.

[0003] Physical remediation: directly separates or removes pollutants through methods such as excavation, soil replacement, and thermal desorption, with rapid results; Chemical remediation: Utilizing chemical reactions such as oxidation-reduction, neutralization, and precipitation to transform pollutants and reduce their toxicity; Bioremediation: It relies on the absorption and degradation of soil by plants and microorganisms, which is environmentally friendly and low-cost.

[0004] Chemical remediation requires the use of chemicals. The current remediation method involves manually spraying chemicals onto the soil. In this method, the chemicals are only sprayed onto the soil surface and cannot reach the deeper parts of the soil, resulting in a small remediation area and poor effect.

[0005] Therefore, it is necessary to invent an intelligent remediation device for grassland soil pollution to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides an intelligent remediation device for grassland soil pollution, thereby resolving the issues raised in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an intelligent remediation device for grassland soil pollution, comprising: a roller, an external mounting frame for the roller, and a fully injecting component on the roller to allow the agent to fully contact the soil; The full-injection component includes: Insert rod, sealing ring, nozzle, slider, clearance assembly, injection assembly; The insertion rods are equidistantly arranged around the outside of the drum. The insertion rods have a channel inside, and the closing ring is disposed in the channel. The spray holes are equidistantly arranged around the closing ring and the insertion rods. The inner wall of the insertion rods has symmetrically arranged grooves. The slider is slidably installed in the grooves and is fixedly connected to the closing ring. The avoidance component is disposed inside the drum. The avoidance component can drive the insertion rod to avoid contact with stones in the soil. The injection component is used to inject a chemical agent into the insertion rods.

[0008] Furthermore, the avoidance component includes: Brackets, rings, springs, and elastic closures; The brackets are configured in multiple groups, each group containing two brackets. The multiple groups of brackets are equidistantly fixed inside the roller. The roller has a movable hole on its outside. The insertion rod is disposed in the movable hole. The brackets are symmetrically distributed on both sides of the insertion rod. The elastic closure connects the inner wall of the movable hole to the insertion rod. The ring frame is slidably installed inside the bracket. The spring fixes the side of the ring frame away from the movable hole to the bracket. The ring frame is connected to the insertion rod.

[0009] Furthermore, the injection assembly includes: Fixed plate, annular cavity, injection tube, drug injection equipment; The annular cavity is located inside the roller. The injection tube is fixedly connected to the mounting bracket through the fixing plate. One end of the injection tube extends through the middle of one side of the roller into the annular cavity. The injection tube is rotatably connected to the roller. A sealing ring is provided on the outside of the injection tube. The sealing ring is located in the contact area between the injection tube and the roller. The discharge end of the drug injection device is connected to one end of the injection tube.

[0010] Furthermore, a torsion spring is sleeved on the outside of the insertion rod, and the two ends of the torsion spring are fixedly connected to the insertion rod and the ring frame respectively. The ring frame is provided with a rotating component that can drive the insertion rod to rotate.

[0011] Furthermore, the rotating assembly includes: Arc-shaped block, baffle, electromagnet, storage battery; The arc-shaped blocks are symmetrically and fixedly installed on the outside of the insert rod. The ring frame has an annular groove inside, and the arc-shaped blocks are slidably installed in the annular groove. The baffles are symmetrically and fixedly installed in the annular groove, and the arc-shaped blocks abut against the baffles. The electromagnets are fixedly installed inside the annular grooves. The arc-shaped blocks are made of iron, and the outside of the arc-shaped blocks is galvanized. The storage battery is located outside the drum, and the storage battery supplies power to the electromagnets.

[0012] Furthermore, the elastic closure is made of rubber, and the elastic closure is fixedly sleeved on the outside of the insertion rod, with the outer side of the elastic closure being fixedly connected to the inner wall of the movable hole.

[0013] Furthermore, when the insert rod rotates to above the central axis of the drum, the closing ring can descend under the action of gravity, causing the nozzles on the closing ring and the insert rod to be misaligned. When the insert rod rotates to below the central axis of the drum, the closing ring can reset under the action of gravity, causing the nozzles on the closing ring and the insert rod to be aligned.

[0014] Furthermore, the spring force can support the insertion of the rod into the soil when the rod is not in contact with the stone.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention enables the spraying of agents onto both the soil surface and the soil interior, resulting in a larger repair area and better repair effect. When the injection rod comes into contact with a stone, the avoidance component can avoid damage to the rod, and allow the remaining rods that are not in contact with the stone to be inserted into the soil normally for normal injection of agents. 2. This invention drives the rotation of the insert rod through a rotating component, which can increase the coverage of the pesticide and throw out the soil in the nozzle, avoiding nozzle blockage and ensuring normal pesticide spraying.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] This invention provides an intelligent remediation device for grassland soil pollution, such as... Figures 1 to 6 As shown, it includes: a roller 1, an installation frame 2 on the outside of the roller 1, and a fully injecting component on the roller 1 that allows the agent to fully contact the soil; The full injection assembly includes: insert rod 3, sealing ring 4, nozzle 5, slider 6, clearance assembly, and injection assembly; Insert rods 3 are equidistantly arranged around the outside of the drum 1. The inside of the insert rods 3 is provided with a channel. The sealing ring 4 is set in the channel. The spray holes 5 are equidistantly arranged around the sealing ring 4 and the insert rods 3. The inner wall of the insert rods 3 is symmetrically provided with sliding grooves. The slider 6 is slidably installed in the sliding grooves. The slider 6 is fixedly connected to the sealing ring 4. The avoidance component is set inside the drum 1. When the insert rods 3 come into contact with stones in the soil, the avoidance component can drive the insert rods 3 to avoid them. The liquid injection component is used to inject the agent into the insert rods 3.

[0019] In use, the mounting frame 2 is connected to an external vehicle. The vehicle pushes the mounting frame 2, which carries the roller 1 along the surface of the soil to be repaired. The agent is injected into the insertion rod 3 through the injection component. As the roller 1 rolls, the closed ring 4 inside the insertion rod 3 located above the central axis of the roller 1 descends under the action of gravity, causing the spray hole 5 on the insertion rod 3 to be misaligned with the spray hole 5 on the closed ring 4, thus closing the spray hole 5 on the insertion rod 3. The closed ring 4 inside the insertion rod 3 located below the central axis of the roller 1 does not move along the inside of the insertion rod 3, causing the spray hole 5 to open. The agent is sprayed out through the spray hole 5 to repair the soil surface. At the same time, part of the insertion rod 3 will be inserted into the soil, allowing the sprayed agent to flow into the soil. This allows the agent to be sprayed both inside and outside the soil, resulting in a larger repair area and better repair effect. By closing the spray hole 5 on the insertion rod 3 located above the central axis of the roller 1, the agent is prevented from dripping onto the surface of the roller 1, thus avoiding waste. If, during the movement of the roller 1 and the insertion rod 3, the insertion rod 3, which is about to be inserted into the soil, comes into contact with a stone, and if the mounting frame 2 and the vehicle are fixedly connected, the insertion rod 3 will get stuck after contacting the stone, which may easily cause damage to the insertion rod 3. If the mounting frame 2 and the vehicle are slidably connected, that is, the mounting frame 2 and the roller 1 can slide relative to the vehicle in the vertical direction, when the insertion rod 3 comes into contact with the stone, the insertion rod 3 will push the roller 1 upward, causing the other insertion rods 3 below to rise as well, making it impossible for all the insertion rods 3 below to enter the soil, thus preventing the injection of pesticide into the soil. Therefore, when the lower insertion rod 3 comes into contact with the stone, the avoidance component drives the insertion rod 3 to avoid it, causing the insertion rod 3 to retract into the roller 1. In this way, if the mounting frame 2 is fixedly connected to the vehicle, the retraction can prevent the insertion rod 3 from being damaged. If the mounting frame 2 is slidably connected to the vehicle, the retraction can prevent the other insertion rods 3 from rising and still insert them into the soil, so that the agent can be injected into the soil normally.

[0020] like Figure 2 and Figure 3 As shown, the obstacle avoidance assembly includes: bracket 7, ring frame 8, spring 9, and elastic closure 10; The brackets 7 are configured in multiple groups, each group of brackets 7 contains two brackets 7. The multiple groups of brackets 7 are fixedly installed at equal intervals inside the roller 1. The roller 1 has a movable hole on its outside. The insertion rod 3 is set in the movable hole. The brackets 7 are symmetrically distributed on both sides of the insertion rod 3. The elastic sealing member 10 connects the inner wall of the movable hole with the insertion rod 3. The ring frame 8 is slidably installed inside the brackets 7. The spring 9 fixes the side of the ring frame 8 away from the movable hole to the bracket 7. The ring frame 8 is connected to the insertion rod 3.

[0021] The elastic sealing member 10 can seal the gap between the insertion rod 3 and the movable hole to prevent leakage. When the lower insertion rod 3 comes into contact with the stone, the insertion rod 3 is squeezed by the stone and retracts into the roller 1, causing the ring frame 8 to slide relative to the support 7, thereby compressing the spring 9. When the insertion rod 3 leaves the stone, the spring 9 resets and drives the ring frame 8 and the insertion rod 3 to reset.

[0022] like Figure 1 and Figure 2 As shown, the injection assembly includes: a fixing plate 11, an annular cavity 12, an injection tube 13, and an injection device (not shown in the figure). The annular cavity 12 is located inside the roller 1. The injection pipe 13 is fixedly connected to the mounting bracket 2 through the fixing plate 11. One end of the injection pipe 13 extends through the middle of one side of the roller 1 into the annular cavity 12. The injection pipe 13 is rotatably connected to the roller 1. A sealing ring is provided on the outside of the injection pipe 13. The sealing ring is located in the contact area between the injection pipe 13 and the roller 1. The discharge end of the drug injection device is connected to one end of the injection pipe 13. The drug injection device is a device that can discharge drug liquid in the prior art. The drug injection device is installed on a vehicle. The drug is injected into the injection tube 13 through the injection device. The drug enters the annular cavity 12 and then enters the insertion rod 3, thereby injecting the drug into the insertion rod 3.

[0023] like Figures 3 to 6 As shown, a torsion spring 14 is sleeved on the outside of the insertion rod 3. The two ends of the torsion spring 14 are fixedly connected to the insertion rod 3 and the ring frame 8 respectively. The ring frame 8 is provided with a rotating component that can drive the insertion rod 3 to rotate. The spring 9 and the torsion spring 14 are galvanized.

[0024] The rotating component intermittently rotates the insert rod 3. When the rotating component rotates the insert rod 3, the insert rod 3 torsion spring 14 to cause it to twist and deform. When the rotating component stops rotating the insert rod 3, the torsion spring 14 resets and the insert rod 3 rotates quickly to reset. As the insert rod 3 rotates, the position of the nozzle 5 can be changed, thereby increasing the coverage area of ​​the pesticide. Furthermore, the rapid rotation of the insert rod 3 can dislodge some of the soil located at the nozzle 5, thus preventing the nozzle 5 from becoming clogged and achieving the cleaning of the nozzle 5.

[0025] like Figures 4 to 6 As shown, the rotating assembly includes: an arc block 15, a baffle 16, an electromagnet 17, and a battery 18. The arc-shaped blocks 15 are symmetrically fixedly installed on the outside of the insert rod 3. The ring frame 8 has an annular groove inside, and the arc-shaped blocks 15 are slidably installed in the annular groove. The baffles 16 are symmetrically fixedly installed in the annular groove, and the arc-shaped blocks 15 and the baffles 16 abut against each other. The electromagnets 17 are fixedly installed inside the annular groove. The arc-shaped blocks 15 are made of iron, and the outside of the arc-shaped blocks 15 is galvanized. The storage battery 18 is set outside the drum 1. The storage battery 18 supplies power to the electromagnets 17. The electromagnets 17 are electromagnets that can be used underwater. By charging the storage battery 18, the storage battery 18 stores electricity to supply power to the electromagnets 17.

[0026] When electromagnet 17 is intermittently energized, it becomes magnetic, attracting arc-shaped block 15 to rotate rod 3 clockwise. Rod 3 then twists torsion spring 14, causing it to deform. When electromagnet 17 is de-energized, torsion spring 14 quickly rotates rod 3 back to its original position. By intermittently energizing electromagnet 17, the rod 3 can rotate in conjunction with torsion spring 14.

[0027] like Figure 3 As shown, the elastic closure 10 is made of rubber. The elastic closure 10 is fixedly sleeved on the outside of the insertion rod 3, and the outer side of the elastic closure 10 is fixedly connected to the inner wall of the movable hole.

[0028] This allows the elastic closure 10 to adapt to the tension caused by the movement of the insertion rod 3.

[0029] like Figure 3 As shown, when the insert rod 3 rotates to above the central axis of the drum 1, the sealing ring 4 can descend under the action of gravity, causing the sealing ring 4 and the spray hole 5 on the insert rod 3 to be misaligned. When the insert rod 3 rotates to below the central axis of the drum 1, the sealing ring 4 can reset under the action of gravity, causing the sealing ring 4 and the spray hole 5 on the insert rod 3 to be aligned.

[0030] like Figure 3 As shown, the elastic force of the spring 9 can support the insertion of the rod 3 into the soil when the rod 3 is not in contact with the stone.

[0031] This ensures that the insertion rod 3 can be inserted into the soil normally, enabling the injection of chemicals into the soil.

[0032] A drain port is provided on the lower side of one side of the drum 1. A plunger 19 is threaded into the drain port. The plunger 19 can be removed to recover the residual medicine inside the drum 1.

[0033] Working principle: During use, the mounting frame 2 is connected to an external vehicle. The vehicle pushes the mounting frame 2, which carries the roller 1 along the surface of the soil to be repaired. The agent is injected into the insertion rod 3 through the injection component. As the roller 1 rolls, the closed ring 4 inside the insertion rod 3 located above the central axis of the roller 1 descends under the action of gravity, causing the spray hole 5 on the insertion rod 3 to be misaligned with the spray hole 5 on the closed ring 4, thus closing the spray hole 5 on the insertion rod 3. The closed ring 4 inside the insertion rod 3 located below the central axis of the roller 1 does not move along the inside of the insertion rod 3, causing the spray hole 5 to open. The agent is sprayed out through the spray hole 5 to repair the soil surface. At the same time, part of the insertion rod 3 will be inserted into the soil, allowing the sprayed agent to flow into the soil. This allows the agent to be sprayed both inside and outside the soil, resulting in a larger repair area and better repair effect. By closing the spray hole 5 on the insertion rod 3 located above the central axis of the roller 1, the agent is prevented from dripping onto the surface of the roller 1, avoiding waste. If, during the movement of the roller 1 and the insertion rod 3, the insertion rod 3, which is about to be inserted into the soil, comes into contact with a stone, and if the mounting frame 2 and the vehicle are fixedly connected, the insertion rod 3 will get stuck after contacting the stone, which may easily cause damage to the insertion rod 3. If the mounting frame 2 and the vehicle are slidably connected, that is, the mounting frame 2 and the roller 1 can slide relative to the vehicle in the vertical direction, when the insertion rod 3 comes into contact with the stone, the insertion rod 3 will push the roller 1 upward, causing the other insertion rods 3 below to rise as well, making it impossible for all the insertion rods 3 below to enter the soil, thus preventing the injection of pesticide into the soil. Therefore, when the lower insertion rod 3 comes into contact with the stone, the insertion rod 3 is squeezed by the stone and retracts into the roller 1, causing the ring frame 8 to slide relative to the bracket 7, thereby compressing the spring 9. When the insertion rod 3 leaves the stone, the spring 9 resets and drives the ring frame 8 and the insertion rod 3 to reset. In this way, if the mounting bracket 2 is fixedly connected to the vehicle, the retraction can prevent the insertion rod 3 from being damaged. If the mounting bracket 2 is slidably connected to the vehicle, the retraction can prevent the other insertion rods 3 from rising and still inserting into the soil, so that the agent can be injected into the soil normally. When electromagnet 17 is intermittently energized, it becomes magnetic, attracting arc-shaped block 15 and causing it to rotate clockwise. The rod 3 then twists and deforms due to the torsion spring 14. When electromagnet 17 is de-energized, the torsion spring 14 causes the rod 3 to rotate rapidly and return to its original position. By intermittently energizing electromagnet 17, the rod 3 can rotate in conjunction with the torsion spring 14. As the rod 3 rotates, the position of the nozzle 5 changes, increasing the coverage area of ​​the pesticide. The rapid rotation of the rod 3 also helps to remove some soil from the nozzle 5, preventing clogging and cleaning the nozzle 5.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
