Description

Technical Field

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

[0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to transform toxic and harmful pollutants into harmless substances. Fundamentally speaking, the technical principles of contaminated soil remediation may include: changing the form of pollutants in the soil or the way they are combined with the soil, reducing their mobility and bioavailability in the environment; reducing the concentration of harmful substances in the soil;

[0003] Chemical remediation is the most commonly used soil treatment method. It repairs and improves the soil by fully mixing chemical agents with the soil. At present, for repairing a small area of ​​soil, the soil to be repaired is dug and poured into a mixing treatment box or a mixing treatment tank, and then the soil repair agent is added for mixing and stirring. Most of the existing mixing treatment boxes or mixing treatment tanks simply stir the agent and the soil. The soil blocks in the soil cannot effectively contact the agent, and the soil and the soil repair agent are not mixed sufficiently and evenly, which reduces the soil repair effect.

[0004] The existing utility model document with application number 2023215993331 discloses a soil ecological restoration device, which drives the crushing blade to crush the soil by rotating the hollow shaft, so that the soil falling into the mixing chamber is finer, and at the same time, the soil restoration agent is sprayed from the nozzle on the hollow stirring rod to contact the soil, and the hollow shaft drives the hollow stirring rod to rotate to stir and mix the soil and the soil restoration agent, so that the mixing is more sufficient and uniform, thereby improving the soil restoration efficiency;

[0005] In actual use, the device achieves soil remediation by crushing the agglomerated soil and mixing it with a remediation agent. However, in actual use, when the soil is being crushed, some large dry soil blocks are broken into blocks. Since the dry soil blocks are relatively hard in texture, they are easily stuck between adjacent crushing blades during the initial cutting and stirring of the soil blocks, affecting the efficiency of the crushing blades in cutting and crushing the soil.

[0006] Therefore, a soil ecological restoration device is proposed. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figures 1 to 15 , the technical solution provided by the present invention:

[0049] Embodiment 1:

[0050] A soil ecological restoration device comprises a restoration box 1, a support seat 12 fixedly connected to the bottom of the restoration box 1, four feeding ports 13 opened on the top of the restoration box 1, a panel fixed to the edge of the upper end surface of the restoration box 1, a visual glass 11 embedded and connected to one side of the restoration box 1, the visual glass 11 is convenient for a user to observe the soil treatment state inside the restoration box 1, a sealing plate 14 connected to the other side of the restoration box 1 by screws, the sealing plate 14 is convenient for a user to open, and perform maintenance and installation operations on the internal structure of the restoration box 1, a crushing assembly 3 is arranged inside the restoration box 1, the crushing assembly 3 comprises a crushing roller 31 rotatably connected to the restoration box 1, a semicircular crushing plate 34 is arranged on the lower side of the crushing roller 31, and the crushing plate A slider 341 is provided between 34 and the repair box 1, and the slider 341 is fixed to the crushing plate 34. An arc-shaped slide groove is provided on the inner wall of the repair box 1, and the slider 341 is located inside the slide groove, and the slider 341 is slidably connected to the slide groove. Both ends of the crushing plate 34 are fixedly connected with a screen 33, and one end of the screen 33 away from the crushing plate 34 is provided with a fixed plate 2 32 fixed to the inner wall of the repair box 1, and one end of the fixed plate 2 32 is fixed with a shovel blade 326, and the shovel blade 326 is fitted with the upper end surface of the screen 33. Crushing teeth of a strip structure are evenly distributed and fixed on the upper end surface of the crushing plate 34 and the outside of the crushing roller 31. Screen holes are provided through the surface of the crushing plate 34 between adjacent crushing teeth, and the screen 33 is made of elastic alloy metal;

[0051] Cleaning rings 35 are symmetrically distributed on the outside of the crushing roller 31, and the cleaning rings 35 are movably connected to the crushing roller 31. A motor 15 is fixed to the front end face of the repair box 1, and the output shaft of the motor 15 is fixed to the center of the front end face of the crushing roller 31 through a flange connection. The rear end of the crushing roller 31 is rotatably connected to the inner wall of the repair box 1. Three groups of electric push rods 16 are fixed on the front and rear sides of the repair box 1 in an annular manner with equal distances, and the output shafts of the electric push rods 16 are movably connected to the cleaning rings 35.

[0052] By adopting the above technical solution, the crushing plate 34 is intermittently displaced to the left and right by the driving component 2, and there is a speed difference and opposite movement direction between the displacement of the crushing plate 34 and the crushing roller 31 under intermittent forward and reverse rotation, which can further improve the crushing effect of the soil, and the crushing roller 31 mainly crushes the soil blocks through the crushing teeth distributed in an outer ring at equal distances. In order to avoid some soil blocks from being stuck between adjacent crushing teeth, it is necessary to clean and remove the soil stuck between the crushing teeth. Therefore, during the rotation of the crushing roller 31, the electric push rods 16 on the front and rear sides of the repair box 1 are controlled by the controller to move toward each other, driving the cleaning ring 35 along The surface of the crushing roller 31 moves, and the soil blocks engaged on the surface of the crushing roller 31 are scraped, cleaned and removed. The cleaning ring 35 moving in opposite directions can further squeeze and crush the soil blocks between the two, assisting the crushing roller 31 to improve the crushing efficiency of the soil blocks. At the same time, in order not to affect the opposite movement of the cleaning ring 35 on the surface of the crushing roller 31 in the rotating state, the cleaning ring 35 also rotates with the crushing roller 31. Here, the annular groove 351 and the slip ring 352 sliding connection structure between the output end of the electric push rod 16 and the cleaning ring 35 are designed, so that the cleaning ring 35 can rotate together with the crushing roller 31 and can also be driven to move by the electric push rod 16.

[0053] Specifically, Figure 4 , Figure 8 , Fig. 9 and Fig.10 , Fig.14 , Fig.15 As shown, an annular groove 351 is provided on the outside of the cleaning ring 35 near the output end of the electric push rod 16, and a slip ring 352 is slidably connected in the annular groove 351. The output end of the electric push rod 16 is vertically fixedly connected to the slip ring 352. The inner wall of the cleaning ring 35 is also designed in a tooth-like shape, and the cleaning ring 35 is consistent with the outer wall of the crushing roller 31. The fixed plate 32 is designed in an arc-shaped structure, and the fixed plate 32 is designed in a hollow structure, forming an active cavity 321 inside. One end of the screen 33 extends to the inside of the active cavity 321 through the bottom opening of the active cavity 321. The inner wall of the second plate 32 is rotatably connected to a guide rod 322, the surface of the screen 33 is designed to fit the guide rod 322, a rotation groove 325 is provided in the middle position of the top of the fixed plate 32, and the inside of the rotation groove 325 is rotatably connected to a pulley 324, and a wire rope 323 is provided on the surface of the pulley 324, one end of the wire rope 323 extends through the upper end opening of the active cavity 321 into the active cavity 321 and is fixedly connected to the upper end of the screen 33, the other end of the wire rope 323 is connected to the driving assembly 2, and the number of the second fixed plate 32 is two groups, which are symmetrically distributed on both sides of the inner wall of the repair box 1.

[0054] By adopting the above technical scheme, larger block soil is delivered to the inside of the repair box 1 through the feeding port 13 on the top of the repair box 1. The enclosure installed on the top of the repair box 1 can reduce the probability of soil blocks falling during the delivery process. When the soil blocks enter the inside of the repair box 1, they will first fall into the gap between the crushing roller 31 and the screen 33. At this time, the controller motor 15 drives the crushing roller 31 to rotate intermittently 180 degrees clockwise and counterclockwise, and the crushing roller 31 is used to crush the soil blocks between the screen 33 and the crushing roller 31. The crushed soil particles smoothly pass through the sieve holes on the surface of the screen 33 and fall downward into the mixing chamber for the next step of agent mixed soil repair. In the process of soil crushing, soil particles that meet the mesh number of the screen 33 fall normally, and soil particles that do not meet the mesh number of the screen 33 continue to roll down along the surface of the screen 33 to between the crushing plate 34 and the crushing roller 31. Through the joint action of the crushing roller 31 and the crushing plate 34, the soil particles are crushed again, and the crushed soil falls normally through the sieve holes on the crushing plate 34.

[0055] Specifically, Figure 8 , Fig. 9 , Fig.12 and Fig.13 As shown, the driving assembly 2 is located directly above the crushing roller 31, and the driving assembly 2 includes a fixed plate 25 fixed to the inner wall of the repair box 1, and a movable groove 27 is provided on the upper end of the fixed plate 25 in a front-rear offset manner, and a gear 28 is rotatably connected to the position between the two movable grooves 27, and a reeling rod 24 is fixedly connected to the upper end of the gear 28, and racks 23 are meshed and connected to the outer sides of the gear 28, and a scraper 26 is vertically fixed to the lower side of one end of the two racks 23 away from the gear 28, and the scraper 26 is slidably connected to the movable groove 27, and the lower end of the scraper 26 extends through the movable groove 27 to the lower side of the fixed plate 25 and is arranged to fit with one side of the cleaning ring 35. The scraper bar 26 is in a U-shaped structure and wrapped around the surface of the cleaning ring 35. The scraper bar 26 and the rack 23 form an L-shaped structure. A shaft is fixed to the bottom of the gear 28. The shaft extends to the inside of the fixed plate 25, and a coil spring is sleeved on the outside of the shaft. One end of the coil spring is fixed to the shaft, and the other end is fixed to the fixed plate 25. The upper end surface of the fixed plate 25 is screwed to the box cover 21, and the middle part of the box cover 21 is connected and fixed with a sleeve 22. The winding rod 24 is located inside the sleeve 22, and the outside of the sleeve 22 is penetrated by a hole groove for the extension of the steel wire rope 323 on both sides. The end of the steel wire rope 323 away from the screen 33 is fixed to the winding rod 24.

[0056] By adopting the above technical scheme, when the two groups of cleaning rings 35 move toward each other, the scraper strip 26 will be squeezed, and the scraper strip 26 moves with the cleaning ring 35. When the tops of the two groups of scraper strips 26 pass through the movable groove 27 on the fixed plate 25 and move stably, the racks 23 fixedly connected to the tops of the two groups of scraper strips 26 move toward each other in the box cover 21 on the upper end surface of the fixed plate 25. During the displacement, the rack 23 drives the gear 28 meshing with the rack 23 to rotate counterclockwise. During the counterclockwise rotation of the gear 28, the bottom shaft retracts the winding spring, and the winding spring elastically accumulates potential. At the same time, the winding rod 24 on the top of the gear 28 rotates counterclockwise in the sleeve 22. Two groups of steel wire ropes 323 are fixed to the outside of the winding rod 24, namely, the right steel wire rope 323 and the left steel wire rope 323. One end of the right steel wire rope 323 is fixed to the winding rod 24. Fig.11 As shown, one end of the left wire rope 323 is wound around the outside of the reeling rod 24. When the reeling rod 24 rotates counterclockwise, the right wire rope 323 is reeled in and pulled, while the left wire rope 323 is loosened and released. Conversely, the subsequent cleaning ring 35 is reset, and the gear 28 rotates clockwise under the action of the coil spring, then the right wire rope 323 is loosened and released, and the left wire rope 323 is reeled in. At this time, the rack 23 is reset, and the scraper bar 26 is reset. The scraper bar 26 can also scrape and clean the surfaces of the two sets of cleaning rings 35 in the rotating state to reduce soil adhesion.

[0059] By adopting the above technical solution, soil particles fall onto the mounting plate 15 in the mixing chamber, and then the controller automatically controls the motor 18 on the lower side of the mounting plate 6 to run, and the output shaft of the motor 18 drives the transmission shaft 182 to rotate, driving the liquid storage box 49 on the top of the transmission shaft 182 to rotate, and the liquid storage box 49 drives the external annular equidistantly connected stirring shaft 42 to rotate and displace, and during the displacement of the stirring shaft 42, it moves in the rotating groove 44 opened on the inner wall of the mixing chamber through the slide rail 47, at this time, the gear 2 46 is meshed with the tooth plate 45, driving the gear 2 46 to rotate, and the gear 2 46 passes The connecting rod 48 drives the stirring shaft 42 to rotate, and the stirring shaft 42 drives the external stirring plate 41 to shovel the soil particles on the mounting plate 5, and during the shoveling process, the external repair agent is transported to the liquid storage box 49 through the pipeline through the outer cylinder 183 and the agent groove 184, and then transported to the stirring shaft 42 with a hollow structure, and sprayed on the soil particles in the shoveling state through the nozzle 43 outside the stirring shaft 42, so as to achieve a uniform mixing reaction between the agent and the soil.

Under normal conditions, the feed opening 17 on the opening and closing plate 19 is misaligned with the feed openings 17 on the mounting plate 15 and the mounting plate 26.

The motor 2 18 drives the opening and closing plate 19 to rotate thirty degrees between the mounting plate 1 5 and the mounting plate 2 6 through the electromagnetic ring 191. At this time, the mounting plate 1 5 and the mounting plate 2 6 and the discharge port 17 on the opening and closing plate 19 are completely opened. Then the electromagnetic ring 191 is controlled to be powered off, and the motor 2 18 continues to drive the stirring plate 41 to rotate and rotate, and the soil particles mixed with the repair agent are discharged through the discharge port 17.

[0060] Embodiment 2:

[0061] like Fig.11 As shown, mounting strips 7 with a triangular cross-section are equidistantly distributed on the lower side of the crushing plate 34, both ends of the mounting strips 7 are fixed to the inner wall of the repair box 1, a channel 71 is provided inside the mounting strip 7, a second nozzle 72 is symmetrically embedded in the mounting strip 7, the second nozzle 72 is connected to the channel 71, and the channels 71 in adjacent mounting strips 7 are connected end to end through a hose, and one end of one of the hoses is connected to an external drug supply device.

[0062] By adopting the above technical solution, a triangular-structured mounting bar 7 is used to directly spray the soil particles that fall through the screen 33 and the crushing plate 34 through the second nozzle 72 to achieve mixing of the agent and the soil particles. The internal channel 71 of the mounting bar 7 is connected to the external agent supply equipment through a pipeline. The second method is more suitable for treating soil particles with a smaller falling amount.

[0063] Working principle: When working, the user automatically controls the device of the present application through a controller connected to the motor 15, the motor 2 18, the electric push rod 16 and the electromagnetic ring 191 in the present application from the outside. The controller controls the operation of the equipment, and then the larger block soil is delivered to the inside of the repair box 1 through the loading port 13 on the top of the repair box 1. The enclosure installed on the top of the repair box 1 can reduce the probability of soil blocks falling during the delivery process. When the soil blocks enter the interior of the repair box 1, they will first fall into the gap between the crushing roller 31 and the screen 33. At this time, the controller motor 15 drives the crushing roller 31 to rotate clockwise and counterclockwise by 180. The crushing roller 31 is intermittently rotated, and the soil blocks between the screen 33 and the crushing roller 31 are crushed by the crushing roller 31. The crushed soil particles smoothly pass through the sieve holes on the surface of the screen 33 and fall down to the mixing chamber for the next step of medicine-mixed soil repair. In the process of soil crushing, the soil particles that meet the mesh number of the screen 33 fall normally, and the soil particles that do not meet the mesh number of the screen 33 continue to roll down along the surface of the screen 33 to between the crushing plate 34 and the crushing roller 31. Through the joint action of the crushing roller 31 and the crushing plate 34, the soil particles are crushed again, and the crushed soil falls normally through the sieve holes on the crushing plate 34;

[0064] In order to further improve the crushing effect and efficiency of soil blocks, and at the same time accelerate the unqualified soil particles on the screen 33 to fall to the crushing plate 34 for subsequent secondary crushing, the crushing plate 34 in the present application is intermittently displaced left and right by the driving component 2, and there is a speed difference and opposite movement direction between the displacement of the crushing plate 34 and the crushing roller 31 under intermittent forward and reverse rotation, which can further improve the crushing effect of the soil, and the crushing roller 31 mainly crushes the soil blocks through the crushing teeth distributed in an outer ring at equal distances. In order to avoid some soil blocks from being stuck between adjacent crushing teeth, it is necessary to clean and remove the soil stuck between the crushing teeth. Therefore, during the rotation of the crushing roller 31, the front and rear of the repair box 1 The electric push rods 16 on both sides are controlled to move toward each other through the controller, driving the cleaning ring 35 to move along the surface of the crushing roller 31, scraping and cleaning the soil blocks engaged on the surface of the crushing roller 31, and the cleaning rings 35 moving toward each other can further perform extrusion-type crushing treatment on the soil blocks between the two, assisting the crushing roller 31 to improve the crushing efficiency of the soil blocks. At the same time, in order not to affect the opposite movement of the cleaning rings 35 on the surface of the crushing roller 31 in a rotating state, the cleaning rings 35 also rotate with the crushing roller 31. Here, by designing the annular groove 351 and the sliding connection structure of the slip ring 352 between the output end of the electric push rod 16 and the cleaning ring 35, the cleaning ring 35 can be rotated together with the crushing roller 31, and can also be driven to move by the electric push rod 16;

[0065] When the two groups of cleaning rings 35 move toward each other, the scraper strips 26 will be squeezed, and the scraper strips 26 will move with the cleaning rings 35. When the tops of the two groups of scraper strips 26 pass through the movable grooves 27 on the fixed plate 25 and move stably, the racks 23 fixedly connected to the tops of the two groups of scraper strips 26 will move toward each other in the box cover 21 on the upper end surface of the fixed plate 25. During the displacement, the rack 23 will drive the gear 28 meshing with the rack 23 to rotate counterclockwise. During the counterclockwise rotation of the gear 28, the bottom shaft retracts the winding spring, and the winding spring elastically accumulates potential. At the same time, the winding rod 24 on the top of the gear 28 rotates counterclockwise in the sleeve 22. Two groups of steel wire ropes 323 are fixed to the outside of the winding rod 24, namely, the right steel wire rope 323 and the left steel wire rope 323. One end of the right steel wire rope 323 is fixed to the winding rod 24. Fig.11 As shown, one end of the left wire rope 323 is wound around the outside of the reeling rod 24. When the reeling rod 24 rotates counterclockwise, the right wire rope 323 is reeled in and pulled, while the left wire rope 323 is loosened and released. Conversely, the subsequent cleaning ring 35 is reset, and the gear 1 28 rotates clockwise under the action of the coil spring, so the right wire rope 323 is loosened and released, and the left wire rope 323 is reeled in. At this time, the rack 23 is reset, and the scraper bar 26 is reset. The scraper bar 26 can also scrape and clean the surfaces of the two sets of cleaning rings 35 in the rotating state to reduce soil adhesion.

[0066] When the right wire rope 323 is reeled in and pulled, the right wire rope 323 pulls the top of the screen 33 in the movable cavity 321 in the right fixed plate 32 through the pulley 324, and the screen 33 rolls through the guide rod 322, deforms and moves upward in the movable cavity 321, and the bottom of the screen 33 is connected to the crushing plate 34, which pulls the crushing plate 34 to move to the right side of the repair box 1. At this time, not only the rotation direction of the crushing roller 31 is opposite to the displacement direction of the crushing plate 34, but there is also a speed difference between the two, which can further improve the crushing effect of the soil blocks between the two. Similarly, in the subsequent reset, when the reeling rod 24 rotates counterclockwise, the screen 33 is pulled by the left wire rope 323 to The crushing plate 34 moves to the left, and the movement of the crushing plate 34 is mainly realized by slidingly connecting the slider 341 designed between the inner wall of the repair box 1 and the slide groove in order to maintain stability. In order to prevent the soil block from entering the slide groove, the user can replace the slider 341 and the slide groove structure with an arc-shaped slide rail structure, or fix a rubber shielding sheet between the two sides of the slider 341 and the two ends of the slide groove; when the screen 33 moves and displaces in the fixed plate 32, the shovel blade 326 fixed at one end of the fixed plate 32 can also scrape and clean the soil attached to the surface of the screen 33 or the granular soil blocked in the mesh of the screen 33, so as to reduce the probability of attachment and blockage of the surface of the screen 33;

[0067] according to Fig.12 As shown, it can be seen that the wire rope 323 and the fixing plate 25 are hidden in the top of the repair box 1, so they will not be disturbed by the falling soil blocks.

[0068] The qualified soil particles passing through the screen 33 and the crushing plate 34 fall into the mixing chamber in the repair box 1 for subsequent mixing of soil and repair agent. There are two mixing structures designed here. The working principle of the first one is as follows:

[0069] Soil particles fall onto the mounting plate 15 in the mixing chamber, and then the controller automatically controls the motor 18 on the lower side of the mounting plate 16 to run. The output shaft of the motor 18 drives the transmission shaft 182 to rotate, driving the liquid storage box 49 on the top of the transmission shaft 182 to rotate. The liquid storage box 49 drives the external annular equidistantly connected stirring shaft 42 to rotate and displace, and during the displacement of the stirring shaft 42, it moves in the rotating groove 44 provided on the inner wall of the mixing chamber through the slide rail 47. At this time, the gear 2 46 is meshed with the tooth plate 45 to drive the gear 2 46 to rotate, and the gear 2 46 drives the stirring shaft through the connecting rod 48. The mixing shaft 42 rotates, and the mixing shaft 42 drives the external mixing plate 41 to shovel the soil particles on the mounting plate 5. In the shoveling process, the external repair agent is transported to the liquid storage box 49 through the pipeline, the outer cylinder 183, and the agent channel 184, and then transported to the mixing shaft 42 with a hollow structure, and sprayed on the soil particles in the shoveling state through the nozzle 43 outside the mixing shaft 42, so as to achieve a uniform mixing reaction between the agent and the soil. After a certain period of mixing, the opening and closing plate 19 between the mounting plate 15 and the mounting plate 26 automatically controls the internal electromagnetic ring 191 to conduct electricity through the controller. The raw magnetic attraction is magnetically attracted to the transmission shaft 182. In a normal state, the feed opening 17 opened on the opening and closing plate 19 is misaligned with the feed openings 17 on the mounting plate 15 and the mounting plate 26. The upper and lower feed openings 17 of the opening and closing plate 19 are located in the middle of the adjacent feed openings 17 on the mounting plate 15 and the mounting plate 26. For example, six groups of feed openings 17 are evenly spaced on the mounting plate 15, the opening and closing plate 19 and the mounting plate 26. The angle between the adjacent feed openings 17 is sixty degrees. The feed opening 17 on the opening and closing plate 19 is located in the middle of the upper and lower feed openings 17 on the mounting plate 15 and the mounting plate 26. Therefore, the upper and lower feed openings 17 of the opening and closing plate 19 are The angle of the discharge port 17 on the mounting plate 1 5 is thirty degrees, so the subsequent controller only needs to control the electromagnetic ring 191 to conduct electricity to generate magnetic force and magnetically fix it with the transmission shaft 182, and the motor 2 18 drives the opening and closing plate 19 to rotate thirty degrees between the mounting plate 1 5 and the mounting plate 2 6 through the electromagnetic ring 191. At this time, the mounting plate 1 5 and the mounting plate 2 6 and the discharge port 17 on the opening and closing plate 19 are completely opened, and then the electromagnetic ring 191 is controlled to be powered off, and the motor 2 18 continues to drive the stirring plate 41 to rotate and rotate, and the soil particles mixed with the repair agent are discharged through the discharge port 17;

[0070] The second method cancels the first agent delivery method and adopts a triangular-structured mounting bar 7 to directly spray the soil particles falling through the screen 33 and the crushing plate 34 through a second nozzle 72 to achieve mixing of the agent and the soil particles. The internal channel 71 of the mounting bar 7 is connected to the external agent supply equipment through a pipeline. The second method is more suitable for treating soil particles with a small falling amount.
