Description

Technical Field

[0001] The present invention relates to the technical field of deep soil remediation, and specifically to a directional injection type deep soil remediation linkage device. Background Art

[0002] In traditional soil remediation operations, a phased mechanized construction mode is usually adopted, that is, special trench-digging equipment is first used to excavate the soil, and then transport vehicles are used to transfer the contaminated soil to a centralized treatment area for repair operations such as crushing and chemical agent mixing. Finally, the repaired soil is backfilled into the in-situ trench. This operation mode has significant technical defects: on the one hand, the connection of multiple processes leads to a long operation cycle, high labor costs, and the risk of dust pollution and cross-contamination during the soil transfer process; on the other hand, it is difficult to achieve uniform mixing of the chemical agent and the soil in centralized repair treatment, and there are often problems of uneven chemical agent distribution or excessive dosing, which not only affects the repair quality but also causes waste of resources; in addition, repeated entry and exit of heavy transport equipment in the operation area will cause serious rolling damage to the surrounding soil, especially in soft geological conditions such as farmland, it is more likely to cause secondary compaction damage. Therefore, a directional injection type deep soil remediation linkage device is proposed. Summary of the Invention

[0003] The purpose of the present invention is to provide a directional injection type deep soil remediation linkage device to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A directional injection type deep soil remediation linkage device, including a machine body. A trench-digging support is provided on the machine body. A driving sprocket and a driven sprocket are respectively rotatably connected to the upper end and the lower end of the trench-digging support. A chain is drivingly connected to the driving sprocket and the driven sprocket. A plurality of blades for excavating soil are evenly arranged on the outer surface of the chain. The right side of the machine body is the advancing end. When the blades on the chain rotate to the right side, the ends of the blades bend upward, which is convenient for cutting the soil and at the same time can lift the cut soil upward. In addition, a protective tile is provided on the machine body and above the chain. A channel for transporting soil is formed between the protective tile and the chain. A soil mixing plate is provided at one end of the trench-digging support on the machine body. The soil mixing plate is used to receive the soil excavated and lifted by the blades. A first rotating rod is provided at the end of the soil mixing plate far away from the trench-digging support. The first rotating rod is rotatably connected to the machine body. The end of the soil mixing plate close to the trench-digging support is inclined upward and swings up and down around the first rotating rod;

[0005] Above the body, there is a material box fixedly connected for storing chemical repair agents. The chemical repair agents can neutralize harmful substances in the soil. At the lower end of the material box, there is a discharge tube. A guide tube is arranged on the discharge tube. The lower end of the guide tube is connected to one end of the soil mixing plate close to the trench opening support. The guide tube can introduce the chemical repair agents onto the soil mixing plate. At the upper end of the guide tube, there is a feed port communicating with the discharge tube. At the lower end of the guide tube, there is a discharge port for introducing the chemical repair agents onto the soil mixing plate.

[0006] Preferably, a driving assembly for driving the soil mixing plate to swing is arranged on the body and below the soil mixing plate. The driving assembly includes a second rotating rod. The second rotating rod is rotationally connected to the body through a motor and is located below the soil mixing plate. The motor is fixedly connected to the side wall of the body. The output shaft of the motor is in transmission connection with one end of the second rotating rod. When the motor is started, the output shaft of the motor drives the second rotating rod to rotate. A plurality of eccentric rods are fixed on the second rotating rod. A push-pull rod is rotationally connected to each of the plurality of eccentric rods. The end of the push-pull rod is rotationally connected to the lower side wall of the soil mixing plate. When the motor is started and drives the second rotating rod to rotate, the eccentric rods rotate around the second rotating rod. At this time, the eccentric rods can drive the soil mixing plate to swing up and down through the push-pull rods.

[0007] Preferably, a first rotating ball is rotationally connected to the bottom of the discharge tube. The upper end of the guide tube is slidably connected to the first rotating ball. The lower end of the guide tube is fixedly connected to a second rotating ball;

[0008] A material leveling groove is arranged on the soil mixing plate. A rotating groove is opened on the soil mixing plate and above the material leveling groove. The second rotating ball is rotationally connected to the inside of the rotating groove. The discharge port is communicated with the material leveling groove;

[0009] When the soil mixing plate swings downward, the soil mixing plate pulls the guide tube to slide downward. The feed port on the guide tube slides into the first rotating ball. At this time, the feed port and the discharge tube are in a separated state, and the guide tube cannot guide the chemical repair agents in the discharge tube downward.

[0010] When the soil mixing plate swings upward, the soil mixing plate pushes the guide tube upward. The feed port on the guide tube slides into the discharge tube. At this time, the feed port is communicated with the discharge tube. The chemical repair agents in the discharge tube enter the guide tube from the feed port. The guide tube guides the chemical repair agents to the discharge port, causing the chemical repair agents to fall from the discharge port into the material leveling groove. Then, the chemical repair agents slide from the material leveling groove to the surface of the soil mixing plate and are mixed with the soil.

[0011] Preferably, the number of the discharge tubes is multiple. The multiple discharge tubes are evenly distributed at the lower end of the material box. And a guide tube is arranged between each discharge tube and the soil mixing plate. The guide tubes are arranged for discharging materials along the width direction of the soil mixing plate.

[0012] Preferably, a plurality of material dispersing cones are fixedly connected inside the material leveling tank, and the plurality of material dispersing cones are respectively located below the corresponding discharge ports. When the chemical repair agent falls from the discharge port into the material leveling tank, the chemical repair agent first lands on the material dispersing cones, and the conical surfaces of the material dispersing cones disperse the chemical repair agent around, so that the chemical repair agent is evenly distributed in the material leveling tank. In this way, when the chemical repair agent in the material leveling tank slides out of the material leveling tank, it can be evenly mixed with the soil, avoiding the concentrated distribution of the chemical repair agent.

[0013] Preferably, a sieve plate is arranged above the soil mixing plate. One end of the sieve plate is rotatably connected to one end of the soil mixing plate close to the trenching support. The other end of the sieve plate inclines downward and is fixedly connected with a guide rod. The guide rod is slidably connected in a horizontal guide groove opened on the machine body;

[0014] A discharge plate is arranged on the machine body and on one side of the sieve plate. A discharge port is opened on the machine body and on one side of the discharge plate. The upper surface of the discharge plate is inclined, and the discharge port is located on the lower side of the discharge plate.

[0015] Preferably, a plurality of impact rods are arranged on the upper surface of the soil mixing plate, and the upper ends of the plurality of impact rods penetrate through the sieve plate and extend above it.

[0016] Preferably, a compaction assembly is arranged at the rear end of the machine body. The compaction assembly includes two connecting blocks, which are respectively arranged on both sides of the machine body. A pressure roller for pressing the soil is rotatably connected between the two connecting blocks, and anti-slip lines are evenly arranged on the surface of the pressure roller.

[0017] Preferably, the compaction assembly further includes two vertical rods, which are respectively fixedly connected to both sides of the machine body. The two connecting blocks are respectively slidably sleeved on the vertical rods on the same side, and springs for elastically pressing the connecting blocks downward are sleeved on the vertical rods.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention drives the blade to cut the soil and simultaneously complete the soil lifting through the rotating chain, and cooperates with the dynamic swinging mechanism of the soil mixing plate to synchronously realize soil fragmentation, chemical repair agent mixing and backfilling operations during the trenching process, effectively shortening the traditional step-by-step operation process and avoiding the risk of secondary pollution caused by soil transportation. The reciprocating swing of the soil mixing plate not only strengthens the uniform mixing effect of the agent and the soil, but also ensures that the mixed material is accurately backfilled into the original trench, greatly improving the utilization rate of the repair material.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-10, the present invention provides a technical solution: a directional injection type soil deep repair linkage device, including a machine body 1, on which a trench opening support 2 is provided. The upper end and the lower end of the trench opening support 2 are respectively rotatably connected with a driving sprocket 201 and a driven sprocket 202. A chain 203 is drivingly connected between the driving sprocket 201 and the driven sprocket 202. A plurality of blades 204 for excavating soil are evenly arranged on the outer surface of the chain 203. As Figure 1 and Figure 2 shown, the right side of the machine body 1 is the forward end. When the blade 204 on the chain 203 rotates to the right along with the chain 203, the end of the blade 204 bends upward, which is convenient for cutting the soil and can also lift the cut soil upward. In addition, a protective tile 102 is provided on the machine body 1 and above the chain 203. A channel for conveying soil is formed between the protective tile 102 and the chain 203. A soil mixing plate 3 is provided at one end of the machine body 1 and located on the trench opening support 2. The soil mixing plate 3 is used to receive the soil excavated and lifted by the blade 204. A first rotating rod 301 is provided at the end of the soil mixing plate 3 far away from the trench opening support 2. The first rotating rod 301 is rotatably connected to the machine body 1. The end of the soil mixing plate 3 close to the trench opening support 2 is inclined upward and swings up and down around the first rotating rod 301;

[0032] A material box 5 for storing chemical repair agent is fixedly connected above the machine body 1. The chemical repair agent can neutralize harmful substances in the soil. A discharge tube 501 is provided at the lower end of the material box 5. A guide tube 502 is provided on the discharge tube 501. The lower end of the guide tube 502 is connected to the end of the soil mixing plate 3 close to the trench opening support 2. The guide tube 502 can introduce the chemical repair agent onto the soil mixing plate 3. An inlet 5021 communicating with the discharge tube 501 is provided at the upper end of the guide tube 502. An outlet 5022 for introducing the chemical repair agent onto the soil mixing plate 3 is provided at the lower end of the guide tube 502.

[0033] As Figure 1 shown, a plurality of ear plates 101 are fixed on the side wall of the machine body 1. The machine body 1 is connected to the robotic arm of the external vehicle body through the plurality of ear plates 101;

[0034] During operation, the chain 203 on the trench opening support 2 is run (the chain 203 rotates in the direction of the arrow as Figure 2 shown), and then the robotic arm of the external vehicle body is used to drive the machine body 1 to move horizontally downward, so that the chain 203 on the trench opening support 2 cuts into the ground (as Figure 10As shown in the figure, at this time, the external vehicle body is used to drive the machine body 1 to move forward. In this way, the blades 204 on the chain 203 cut the soil, a groove is formed under the machine body 1, the cut soil is lifted upward by the blades 204, and finally the lifted soil passes over the chain 203 and falls on the soil mixing plate 3. At this time, the soil falling on the soil mixing plate 3 is mixed with the chemical remediation agent;

[0035] Meanwhile, under the operation of the driving assembly 4, the soil mixing plate 3 swings up and down, enabling the soil mixing plate 3 to move the soil and the chemical remediation agent toward one end away from the trench support 2. During the movement, the soil and the chemical remediation agent can be fully mixed, and the mixed soil and chemical remediation agent are backfilled into the trench from one end of the soil mixing plate 3 away from the trench support 2, realizing soil remediation and continuous operation.

[0036] In addition, as Figure 10 shown, the forward end of the machine body 1 is curved upward in an arc, so as to ensure that the machine body 1 can smoothly move along the ground.

[0037] As Figure 1-Figure 3 and Figure 6 shown, in order to be able to drive the end of the soil mixing plate 3 close to the trench support 2 to swing up and down. Specifically, a driving assembly 4 for driving the soil mixing plate 3 to swing is provided on the machine body 1 and below the soil mixing plate 3. The driving assembly 4 includes a second rotating rod 401. The second rotating rod 401 is rotatably connected to the machine body 1 through a motor 402 and is located below the soil mixing plate 3. As Figure 1 shown, the motor 402 is fixedly connected to the side wall of the machine body 1, and the output shaft of the motor 402 is drivingly connected to one end of the second rotating rod 401. When the motor 402 is started, the output shaft of the motor 402 drives the second rotating rod 401 to rotate. A plurality of eccentric rods 403 are fixed on the second rotating rod 401, and a push-pull rod 404 is rotatably connected to each of the plurality of eccentric rods 403. The end of the push-pull rod 404 is rotatably connected to the lower side wall of the soil mixing plate 3. When the motor 402 is started and drives the second rotating rod 401 to rotate, the eccentric rod 403 rotates around the second rotating rod 401. At this time, the eccentric rod 403 can drive the soil mixing plate 3 to swing up and down through the push-pull rod 404.

[0038] As Figure 1-Figure 4 shown, in order to be able to quantitatively mix the chemical remediation agent and the soil. Specifically, a first rotating ball 503 is rotatably connected to the bottom of the discharge barrel 501, the upper end of the guide pipe 502 is slidably connected to the first rotating ball 503, and the lower end of the guide pipe 502 is fixedly connected to a second rotating ball 504;

[0039] A material spreading groove 302 is provided on the concrete plate 3. A rotating groove 303 is formed on the concrete plate 3 and above the material spreading groove 302. The second rotating ball 504 is rotatably connected to the inside of the rotating groove 303. The discharge port 5022 communicates with the material spreading groove 302.

[0040] When the concrete plate 3 swings downward, the concrete plate 3 pulls the material guiding pipe 502 to slide downward. The feed port 5021 on the material guiding pipe 502 slides into the first rotating ball 503. At this time, the feed port 5021 is in a separated state from the discharge cylinder 501, and the material guiding pipe 502 cannot guide the chemical repair agent in the discharge cylinder 501 downward.

[0041] When the concrete plate 3 swings upward, the concrete plate 3 pushes the material guiding pipe 502 upward. The feed port 5021 on the material guiding pipe 502 slides into the discharge cylinder 501. At this time, the feed port 5021 communicates with the discharge cylinder 501. The chemical repair agent in the discharge cylinder 501 enters the material guiding pipe 502 from the feed port 5021. The material guiding pipe 502 guides the chemical repair agent to the discharge port 5022, causing the chemical repair agent to fall from the discharge port 5022 into the material spreading groove 302. Then the chemical repair agent slides from the material spreading groove 302 to the surface of the concrete plate 3 and mixes with the soil.

[0042] In addition, the second rotating ball 504 is rotatably connected in the rotating groove 303, the first rotating ball 503 is rotatably connected in the discharge cylinder 501, and the material guiding pipe 502 is slidably connected in the first rotating ball 503. When the concrete plate 3 swings, it can ensure that the material guiding pipe 502 quantitatively guides the chemical repair agent into the material spreading groove 302.

[0043] As Figure 1-Figure 3 shown, in order to further mix the chemical repair agent and the soil evenly, specifically, the number of the discharge cylinders 501 is multiple. The multiple discharge cylinders 501 are evenly distributed at the lower end of the material box 5. And a material guiding pipe 502 is provided between each discharge cylinder 501 and the concrete plate 3. The material guiding pipes 502 are arranged for discharging along the width direction of the concrete plate 3.

[0044] Specifically, a plurality of material scattering cones 6 are fixedly connected inside the material spreading groove 302. The plurality of material scattering cones 6 are respectively located below the corresponding discharge ports 5022. When the chemical repair agent falls from the discharge port 5022 into the material spreading groove 302, the chemical repair agent first lands on the material scattering cones 6. The conical surfaces of the material scattering cones 6 disperse the chemical repair agent around, so that the chemical repair agent is evenly distributed in the material spreading groove 302. In this way, when the chemical repair agent in the material spreading groove 302 slides out of the material spreading groove 302, it can be evenly mixed with the soil, avoiding the concentrated distribution of the chemical repair agent.

[0045] As Figure 1-Figure 3 、 Figure 5 、 Figure 7 And Figure 8As shown, in order to screen out larger impurities in the soil, specifically, a sieve plate 7 is arranged above the soil mixing plate 3. One end of the sieve plate 7 is rotatably connected to one end of the soil mixing plate 3 close to the trenching support 2. The other end of the sieve plate 7 inclines downward and is fixedly connected with a guide rod 701. The guide rod 701 is slidably connected in a horizontal guide groove 103 formed on the machine body 1;

[0046] On the machine body 1 and on one side of the sieve plate 7, a discharge plate 8 is arranged. On one side of the discharge plate 8 and on the machine body 1, a discharge port 104 is formed. The upper surface of the discharge plate 8 is inclined, and the discharge port 104 is located on the lower side of the discharge plate 8.

[0047] When the soil mixing plate 3 swings up and down, the soil mixing plate 3 drives one end of the sieve plate 7 to swing up and down. During the swinging process, the guide rod 701 slides adaptively in the horizontal guide groove 103. Under the swinging of the sieve plate 7, the larger impurities on the sieve plate 7 move towards the discharge plate 8 on the sieve plate 7;

[0048] When the soil lifted by the blade 204 falls on the soil mixing plate 3, the soil will be screened by the sieve plate 7. The soil will pass through the sieve plate 7 and fall on the soil mixing plate 3, while the larger impurities will be intercepted by the sieve plate 7. The larger impurities will move from the upper surface of the sieve plate 7 to the discharge plate 8, and finally, they will be discharged to one side from the discharge port 104, realizing the screening of larger impurities in the soil.

[0049] Specifically, a plurality of impact rods 10 are arranged on the upper surface of the soil mixing plate 3. The upper ends of the plurality of impact rods 10 penetrate through the sieve plate 7 and extend above it.

[0050] The impact rod 10 has two functions. The first function is that when the soil and the chemical repair agent slide on the soil mixing plate 3, the soil and the chemical repair agent impact on the impact rod 10, so that the soil and the chemical repair agent can be scattered, making the mixing of the soil and the chemical repair agent more uniform;

[0051] The second function is that as Figure 7 shown, when the soil mixing plate 3 and the sieve plate 7 swing downward, a section of the impact rod 10 extending above the sieve plate 7 can briefly intercept the impurities on the sieve plate 7, preventing larger impurities from quickly sliding onto the discharge plate 8. The impurities stay on the sieve plate 7 for a long time, which is beneficial to the soil adhering to the impurities to separate from the surface of the impurities. As Figure 8 shown, when the soil mixing plate 3 and the sieve plate 7 swing upward, the upper end of the impact rod 10 is flush with the surface of the sieve plate 7, and the larger impurities on the sieve plate 7 can move towards the discharge plate 8 normally, improving the separation efficiency.

[0052] In addition, the upper surface of the concrete mixing plate 3 is stepped. When the soil slides on the concrete mixing plate 3, when the soil and the chemical repair agent fall from one step to the next step, the soil and the chemical repair agent fall and impact on the next step, and a plurality of sinking grooves 304 are evenly distributed on each step. The plurality of sinking grooves 304 can also change the falling impact degree of the soil and the chemical repair agent on each step, thereby further improving the mixing efficiency.

[0053] As Figure 1 , Figure 2 and 9 shown, in order to compact the backfilled soil, specifically, a compaction assembly 9 is provided at the rear end of the machine body 1. The compaction assembly 9 includes two connecting blocks 901 which are respectively arranged on both sides of the machine body 1. A roller 902 for pressing the soil is rotatably connected between the two connecting blocks 901. Anti-slip grooves are evenly formed on the surface of the roller 902.

[0054] Specifically, the compaction assembly 9 further includes two vertical rods 903 which are respectively fixedly connected to both sides of the machine body 1. The two connecting blocks 901 are respectively slidably sleeved on the vertical rods 903 on the same side, and a spring 904 for elastically pressing the connecting block 901 downward is sleeved on the vertical rod 903.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
