Technical Field

[0001] This application relates to the technical field of soil remediation, and in particular, to a soil remediation method and a soil remediation device. Background Art

[0002] In soil remediation, biochar-based soil conditioners are mainly a type of high-efficiency, low-cost, and environmentally friendly farmland conditioner prepared from agricultural production waste as raw materials, using technologies such as pyrolysis and adding various soil fertility substances.

[0003] Biochar-based soil conditioners can effectively immobilize various organic / inorganic pollutants in the soil, significantly reduce the bioavailability of pollutants, inhibit the absorption of pollutants by crops, and eliminate potential risks to food safety and human health caused by soil pollution; at the same time, biochar-based soil conditioners can also improve the physical and chemical properties of the soil, increase soil fertility, and promote crop growth. In recent years, the research and development of biochar-based soil conditioners have developed rapidly, and there are currently various commercial products on the market. The application of biochar-based conditioners in farmland shows broad prospects in promoting crop yields and controlling pollution treatment.

[0004] For soil remediation, it is usually carried out by a deep plowing and fertilizing device that plows the soil deeply while spreading the biochar-based soil conditioner on the soil. Currently, the deep plowing and fertilizing device includes a device main body, a plow, and a spreader. The plow and the spreader are arranged on the device main body, and the conditioner is stored in the spreader. During soil remediation, the device main body moves forward. At this time, the spreader first spreads the conditioner, and then the plow deeply plows the soil, so that the soil and the conditioner are mixed.

[0005] However, the soil plowed deeply is usually in lumps, and the mixing effect with the conditioner is not ideal, affecting the soil remediation effect. Summary of the Invention

The linkage bar is arranged on the power column. A power spring is sleeved on the outer peripheral side of the power column, and the power spring drives the linkage bar so that the blocking column protrudes out of the spreading hole.

[0049] By adopting the above technical solution, the design of the blocking column and the linkage bar realizes the automatic opening and closing of the spreading hole. During the operation process, the blocking column moves down to open the spreading hole, realizing precise spreading.

[0056] S3: When the plowshare moves forward, the plowshare plowshare plowshare pushes the soil into the driving wheel, and at this time, the feeding piece drives the soil into the mixing trough, and then the conditioner enters the mixing trough, and then the mixing roller crushes the soil while mixing the soil and the conditioner, and finally the mixed soil is discharged from the discharge port.

[0057] By adopting the above technical solution, the soil remediation method realizes the automation of the whole process of soil remediation through turning the soil with a plow and mixing the conditioner in a spreading box. The full mixing of the conditioner and the soil improves the soil structure, promotes microbial activity, and accelerates the degradation of pollutants.

[0069] The following will Figures 1-7 make a further detailed description of the present application in conjunction with the attached

[0070] The embodiment of the present application discloses a soil remediation device.

[0071] Referring to Figure 1 , the soil remediation device includes a body 1. The body 1 is provided with traveling wheels 11. There are multiple traveling wheels 11 and they are evenly arranged at the four corners of the bottom of the body 1. A power motor is fixedly installed on the body 1, and the power motor drives the traveling wheels 11 to rotate, so that the body 1 can move on the ground.

[0072] The soil remediation device further includes a plowshare 12 and a sowing part. The plowshare 12 is fixedly connected to the bottom of the machine body 1. There is one or more plowshares 12. In the embodiment of the present application, the state where there is one plowshare 12 is taken as an example for illustration; on one side of the plowshare 12 is a plowshare part 13, and the plowshare part 13 faces the forward side of the machine body 1. When the machine body 1 advances, the plowshare 12 turns the soil on the ground to both sides of the plowshare part 13.

[0073] See Figure 1 and Figure 2 , the sowing box 2 is fixedly installed at the bottom of the machine body 1. There are multiple sowing boxes 2 and they are arranged oppositely. The plowshare 12 is located between two opposite sowing boxes 2, and the sowing box 2 is located at a position on the side facing away from the plowshare part 13. The sowing box 2 is provided with a mixing cavity 21, and the mixing cavity 21 extends in a certain direction, and the extending direction of the mixing cavity 21 is parallel to the traveling direction of the plowshare 12. One side of the mixing cavity 21 is a feed inlet 211, and the other side of the mixing cavity 21 is a discharge outlet 212. The caliber of the discharge outlet 212 is smaller than that of the discharge outlet 212. When the machine body 1 travels, the soil turned to both sides by the plowshare part 13 enters the mixing cavity 21 through the feed inlet 211.

[0074] The sowing box 2 is rotatably connected with a driving wheel 22. The driving wheel 22 is hollowly arranged and is located in the mixing cavity 21 and close to the feed inlet 211. Two mounting plates 231 are symmetrically fixed on the side wall of the sowing box 2. A rotating roller 23 is rotatably connected between the two mounting plates 231. The rotating roller 23 is located on the side of the feed inlet 211 away from the discharge outlet 212 and is located directly opposite the feed inlet 211. A plurality of stirring blades 232 are fixedly connected to the outer peripheral side of the rotating roller 23, and the stirring blades 232 are arranged at equal intervals along the circumferential direction.

[0075] See Figure 1 and Figure 2 , the sowing box 2 is provided with a driving component 3. The driving component 3 includes a driving motor 31 and a linkage shaft 32. The linkage shaft 32 is rotatably connected to one of the mounting plates 231, and the linkage shaft 32 is fixedly connected and coaxially arranged with the rotating roller 23. The driving motor 31 is fixedly installed on the mounting plate 231. The output shaft of the driving motor 31 is rotatably connected to the mounting plate 231, and the output shaft of the driving motor 31 is fixedly connected and coaxially arranged with the rotating roller 23. When the driving motor 31 is started, the rotating roller 23 is driven to rotate. At this time, the stirring blades 232 stir the soil turned to both sides by the plowshare part 13 into the driving wheel 22 (the driving wheel 22 is marked in Figure 3 ).

[0076] See Figure 4 and Figure 5 , the sowing box 2 is provided with a first transmission component 4. When the rotating roller 23 (the rotating roller 23 is marked in Figure 1 ) rotates, the first transmission component 4 drives the driving wheel 22 to rotate.

[0077] See Figure 4 With Figure 6 , the first transmission assembly 4 includes a transmission gear ring 41, a transmission gear 42, a transmission belt 43 (the transmission belt 43 is marked in Figure 1 ), a connecting shaft 44, a first transmission shaft 45, a transmission helical gear 46 and a connecting helical gear 47; the connecting shaft 44 is rotatably connected to the sowing box 2, the transmission gear 42 is fixedly connected to the outer peripheral side of the connecting shaft 44, and the transmission gear 42 is rotatably connected to the sowing box 2. The transmission gear ring 41 is fixedly connected to the outer peripheral side of the driving wheel 22, the transmission gear ring 41 is rotatably connected to the sowing box 2, and the transmission gear 42 meshes with the transmission gear ring 41.

The transmission helical gear 46 is fixedly connected to the outer peripheral side of the first transmission shaft 45, and the transmission helical gear 46 is rotatably connected to the sowing box 2. The connecting helical gear 47 is fixedly connected to the outer peripheral side of the connecting shaft 44, the connecting helical gear 47 is rotatably connected to the sowing box 2, and the connecting helical gear 47 meshes with the transmission helical gear 46.

[0079] When the linkage shaft 32 (the linkage shaft 32 is marked in Figure 1 ) drives the rotating roller 23 (the rotating roller 23 is marked in Figure 1 ) to rotate, the transmission belt 43 drives the first transmission shaft 45 to rotate. At this time, the connecting helical gear 47 and the transmission helical gear 46 cooperate to drive the connecting shaft 44 to rotate. At this time, the transmission gear 42 and the transmission gear ring 41 cooperate to drive the driving wheel 22 to rotate.

[0080] See Figure 2 With Figure 3 , a feeding piece 221 is fixedly connected to the inner peripheral side wall of the driving wheel 22. There are a plurality of feeding pieces 221 and they are evenly spaced along the circumferential direction. The feeding piece 221 extends obliquely downward from the feeding port 211 to the discharging port 212. When the driving wheel 22 rotates and the feeding piece 221 moves from the bottom of the mixing chamber 21 to the top of the mixing chamber 21, the soil in the driving wheel 22 is driven by the feeding piece 221 to move upward, and then the soil follows the feeding piece 221 and is transmitted from the side of the feeding port 211 to the side of the discharging port 212.

[0081] A mixing box 6 is fixedly installed in the spreading box 2, and the side wall of the mixing box 6 away from the feed inlet 211 seals the discharge outlet 212. The mixing box 6 is provided with a mixing groove 61, and the notch of the mixing groove 61 is located at the top of the mixing box 6. The vertical side wall of the mixing box 6 close to the feed inlet 211 is in sliding contact with the side of the driving wheel 22 facing the discharge outlet 212, and the top end face of the mixing box 6 is located above and adjacent to the central axis of the driving wheel 22.

[0082] A mixing roller 62 is rotatably connected in the mixing box 6. The central axis of the mixing roller 62 is parallel to the central axis of the driving wheel 22. Mixing blades are fixedly connected to the outer peripheral side of the mixing roller 62 along the spiral direction. The spreading box 2 is provided with a second transmission assembly 7. When the driving wheel 22 rotates, the second transmission assembly 7 drives the mixing roller 62 to rotate.

[0083] The second transmission assembly 7 includes a connecting gear 71, a second transmission shaft 72, a connecting belt 73 and a rotating shaft 74. The second transmission shaft 72 is rotatably connected in the spreading box 2. The connecting gear 71 is fixedly connected to the outer peripheral side of the second transmission shaft 72. The connecting gear 71 is rotatably connected in the box wall of the spreading box 2, and the connecting gear 71 meshes with the transmission gear ring 41. The rotating shaft 74 is rotatably connected in the inner box wall of the mixing box 6. The rotating shaft 74 and the mixing roller 62 are fixedly connected and coaxially arranged. The connecting belt 73 is connected end to end and slidably penetrates through the box walls of the mixing box 6 and the spreading box 2. The connecting belt 73 is sleeved on the outer peripheral sides of the rotating shaft 74 and the second transmission shaft 72.

[0084] When the driving wheel 22 rotates, the transmission gear ring 41 drives the second transmission shaft 72 to rotate through the connecting gear 71. At this time, the connecting belt 73 drives the rotating shaft 74 to rotate, so that the mixing roller 62 enters the rotating state. When the soil is driven by the feeding piece 221 to the upper part of the mixing box 6, the soil enters the mixing groove 61. At this time, the mixing roller 62 crushes the soil to reduce the volume of the soil lumps. A discharge port 63 is opened on the side of the mixing box 6 away from the feed inlet 211, and the discharge port 63 is communicated with the discharge outlet 212. The soil in the mixing groove 61 is discharged through the discharge port 63 and finally discharged from the mixing cavity 21 through the discharge outlet 212.

[0085] A stirring shaft 64 is rotatably connected to the box wall on the side of the mixing box 6 away from the discharge outlet 212, and the stirring shaft 64 extends into the driving wheel 22. Stirring blades 641 are fixedly connected to the outer peripheral side of the stirring shaft 64. There are multiple stirring blades 641 and they are evenly spaced along the circumferential direction. A stirring belt 642 is sleeved between the stirring shaft 64 and the rotating shaft 74. When the rotating shaft 74 rotates, the stirring belt 642 drives the stirring shaft 64 to rotate. The rotating direction of the stirring shaft 64 is opposite to the rotating direction of the driving wheel 22. At this time, the stirring blades 641 rotate following the stirring shaft 64, so that the stirring blades 641 cooperate with the feeding blades to initially crush the soil and reduce the volume of the soil.

[0086] A filter grille 65 is provided at the top of the mixing box 6, and the filter grille 65 covers the notch of the mixing tank 61. One side of the filter grille 65 away from the feed port 211 is hinged to one side of the top of the mixing box 6 close to the discharge port 212. A sliding column is fixedly connected to the bottom of the filter grille 65 and close to the feed port 211. A sliding groove for the sliding column to slide up and down is formed in the top of the mixing box 6, and there is a gap between the peripheral wall of the sliding groove and the outer periphery of the sliding column. A driving spring 651 is arranged on the mixing box 6. The driving spring 651 is installed in the sliding groove. The top of the driving spring 651 abuts against the bottom of the sliding column, and the bottom of the driving spring 651 abuts against the bottom wall of the sliding groove. When the driving spring 651 elastically releases, it drives the sliding column to move upward, so that one side of the filter grille 65 close to the feed port 211 moves upward. At this time, the filter grille 65 extends obliquely downward from the side of the feed port 211 to the side of the discharge port 212. The conveying sheet 221 drives the soil to be conveyed onto the filter grille 65. At this time, on the one hand, the filter grille 65 filters out larger soil lumps, and on the other hand, the soil lumps move along the filter grille 65 towards the discharge port 212, reducing the accumulation of soil at the position of the filter grille 65 close to the feed port 211.

The sowing box 2 is fixedly installed with a feeding pipe 51. The feeding pipe 51 communicates with the storage box 5 and the mixing chamber 21, and the bottom pipe orifice of the feeding pipe 51 is directly opposite to the notch of the mixing tank 61. The conditioner in the storage box 5 is input into the mixing tank 61 through the feeding pipe 51.

[0088] See Figure 7 A connecting sleeve 52 is sleeved on the outer periphery of the feeding pipe 51, and a reciprocating thread sleeve 53 is sleeved on the outer periphery of the connecting sleeve 52. A limiting block 521 is fixedly connected to the outer periphery of the connecting sleeve 52, and a limiting groove 531 extending in the vertical direction is formed in the reciprocating thread sleeve 53. The limiting block 521 slides up and down in the limiting groove 531, so that the connecting sleeve 52 and the reciprocating thread sleeve 53 are linked, and at the same time, the reciprocating thread sleeve 53 can axially slide on the outer periphery of the connecting sleeve 52.

[0089] See Figure 6 And Figure 7, a driving nut 24 is fixedly connected inside the box wall of the sowing box 2, and the driving nut 24 is threadedly connected with the reciprocating thread sleeve 53. A power shaft 25 is rotatably connected inside the box wall of the sowing box 2, and a power belt 251 is sleeved between the power shaft 25 and the connecting sleeve 52. A power bevel gear 252 is fixedly connected to the outer peripheral side of the power shaft 25, and the power bevel gear 252 is rotatably connected inside the box wall of the sowing box 2. A linkage bevel gear 441 is fixedly connected to the outer peripheral side of the connecting shaft 44, and the linkage bevel gear 441 is rotatably connected inside the box wall of the sowing box 2. The power bevel gear 252 meshes with the linkage bevel gear 441. When the rotating shaft 74 (marked on the rotating roller 23 in Figure 1 is marked) rotates, the linkage bevel gear 441 drives the power shaft 25 to rotate through the power bevel gear 252. Then, the power shaft 25 drives the connecting sleeve 52 to rotate through the power belt 251, so that the reciprocating thread sleeve 53 enters a rotating state. Then, under the action of the driving nut 24, the reciprocating thread sleeve 53 enters an up-and-down circular motion state.

[0090] A rolling block 54 slides up and down at the bottom of the reciprocating thread sleeve 53. A linkage block 532 is fixedly connected to the outer peripheral side of the reciprocating thread sleeve 53. The rolling block 54 is provided with a linkage groove 549 extending in the vertical direction. The linkage block 532 slides up and down in the linkage groove 549. The reciprocating thread sleeve 53 is provided with a power spring 533. The power spring 533 is installed in the linkage groove 549. One end of the power spring 533 abuts against the top of the linkage block 532, and the other end abuts against the top wall of the linkage groove 549. When the power spring 533 elastically releases, it drives the linkage block 532 to move downward.

[0091] A material groove 541 is formed in the rolling block 54, and the material groove 541 is communicated with the material conveying pipe 51. A plurality of sowing holes 542 are formed at the bottom of the rolling block 54, and the sowing holes 542 are evenly spaced. The sowing holes 542 communicate with the material groove 541. The rolling block 54 is provided with a blocking column 543. The blocking column 543 slides up and down in the sowing hole 542. There are a plurality of blocking columns 543, and they correspond to the sowing holes 542 one by one. A sliding column 544 is fixedly connected to the top of the blocking column 543, and the sliding column 544 is coaxially arranged with the blocking column 543. The outer diameter of the sliding column 544 is smaller than the diameter of the sowing hole 542. A linkage bar 545 is fixedly connected between the sliding columns 544, so that the sliding columns 544 are linked.

[0092] The rolling block 54 is fixedly mounted with a mounting frame 546, and the mounting frame 546 is located in the material trough 541. The mounting frame 546 is provided with a power column 547 that slides up and down, and a linkage bar 545 is fixedly connected to the power column 547. A connecting spring 548 is sleeved on the outer peripheral side of the power column 547, and the top of the connecting spring 548 abuts against the mounting frame 546, and the bottom of the connecting spring 548 abuts against the bottom of the linkage bar 545. When the connecting spring 548 is elastically released, it drives the linkage bar 545 to move downward, so that the blocking column 543 protrudes out of the sowing hole 542. At this time, the conditioner in the material trough 541 can be sown to the mixing trough 61 through the sowing hole 542. When the rolling block 54 moves downward, the rolling block 54 first contacts the filter grille 65 (the filter grille 65 is in Figure 3 ), and then drives the filter grille 65 to move downward until it abuts against the top of the mixing box 6; during the downward movement of the filter grille 65, the rolling block 54 rolls the soil lumps on the filter grille 65 to further reduce the volume of the soil lumps, and during rolling, the blocking column 543 is resisted and slides into the sowing hole 542 to block the sowing hole 542, reducing the possibility of soil blocking the sowing hole 542 during rolling. When the rolling block 54 is away from the filter grille 65, the connecting spring 548 drives the blocking column 543 to protrude to the sowing hole 542, so that the conditioner can be output to the material tank 541, which is convenient for the conditioner to be mixed with the soil.

[0093] The soil remediation device further includes a pulling plate, which is fixedly connected to the bottom of the machine body 1 and is located on the side of the sowing box 2 away from the plowshare 12. When in use, there is a gap between the pulling plate and the ground, and the mixed soil discharged from the discharge port 212 and piled on the ground is flattened, further improving the uniformity of mixing the soil and the conditioner, and reducing the possibility of the conditioner being blown away by the wind.

[0094] The implementation principle of a soil remediation device in the embodiment of the present application is:

[0095] When in use, the conditioner is first stored in the storage box 5, and then the machine body 1 is started, so that the plowshare 12 moves forward, driving the soil to turn over to both sides of the plowshare 13. When the plowshare 12 moves forward, the plowshare 232 plows the soil into the driving wheel 22, and then the feed sheet 221 drives the soil into the mixing trough 61. When the feed sheet 221 drives the soil to move, the plowshare 641 cooperates with the feed sheet 221 to initially crush the soil lumps. When the soil falls on the filter grid 65, the soil with a smaller volume enters the mixing trough 61; at the same time, the rolling block 54 rotates to evenly spread the conditioner into the mixing trough 61, so that the mixing roller 62 can evenly mix the conditioner and soil in the mixing trough 61; when the rolling block 54 spreads the conditioner, the rolling block 54 moves up and down to crush the soil on the filter grid 65, further reducing the volume of soil lumps and improving the mixing effect of the soil and the conditioner. Finally, the mixed soil and conditioner are discharged from the discharge port 212.

[0096] On the other hand, the present application discloses a soil remediation method, comprising the following steps:

[0097] Step 1: Store the conditioner in the storage box 5;

[0098] Step 2: Start the body 1, the body 1 drives the plow head 12 to move forward, and drives the soil to be deflected to both sides of the plowshare part 13;

[0099] Step 3: When the plow head 12 moves forward, the deflecting blade 232 deflects the soil into the driving wheel 22. At this time, the feeding piece 221 drives the soil into the mixing tank 61, then the conditioner enters the mixing tank 61, and then the mixing roller 62 crushes the soil while mixing the soil and the conditioner. Finally, the mixed soil is discharged from the discharge port 212.

[0100] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
