Description

Technical Field

[0001] This invention relates to the field of microbial ecological restoration technology, specifically to a topsoil covering device and method for mine ecological restoration containing microorganisms. Background Technology

[0002] In areas with severe environmental pollution, phytoremediation alone is insufficient to achieve the desired results. Due to excessive levels of heavy metals in the soil, plants struggle to grow, often necessitating the application of microbial fertilizers. However, microbial fertilizers are prone to volatilization in the air, resulting in low utilization rates. Furthermore, during mine ecological restoration, the numerous slopes in mines mean that fertilizers mostly act only on the soil surface and are difficult to penetrate into the soil, reducing the effectiveness of microbial fertilizers in enhancing soil activity and making phytoremediation methods difficult to implement.

[0003] Therefore, there is a need for a topsoil covering device containing microorganisms for mine ecological restoration to solve the above problems. Summary of the Invention

The breaking part includes an insertion rod, which includes a straight section and an inclined section. The inclined section is inclined from the straight section toward the bottom surface. The straight section is hinged to the push plate. A drive mechanism for vertical movement is provided on the bottom side of the straight section.

[0006] Preferably, the top of the insertion plate is provided with a sliding mechanism, the sliding mechanism includes a slide rail, a slider is slidably connected in the slide rail, the slider is fixedly connected to the insertion plate, and a first elastic element is connected between the slider and the slide rail.

[0007] Preferably, the impeller includes an mounting cylinder, the blades include contact blades, the mounting blades are slidably sleeved on the contact blades, the mounting blades are fixedly connected to the mounting cylinder, a second elastic element is provided between the mounting blades and the contact blades, and the contact blades can respectively abut against the insertion plate and the accumulated soil.

[0008] Preferably, a water spray section is provided on the side of the cover portion away from the insertion portion, the water spray section including a nozzle, the nozzle being connected to an external water source via a first booster pump.

[0009] Preferably, the dispensing unit includes a rotatable liquid storage cylinder and two spraying mechanisms. The spraying mechanisms are symmetrically arranged about the center line of the length direction of the push plate, and the spraying mechanisms are connected to the bottom of the liquid storage cylinder through a connecting pipe.

[0010] Preferably, the liquid storage cylinder is provided with a stirring and venting component, which includes a rotating shaft rotatably mounted on the rotating shaft. A venting cylinder is sleeved on the rotating shaft, and an air inlet groove is provided in the venting cylinder, which communicates with the external space. A first stirring rod is provided on the venting cylinder, and a second stirring rod is slidably mounted on the first stirring rod. A scraper is provided on the second stirring rod. The first stirring rod is slidably connected in a cavity in the second stirring rod. A third elastic element is provided between the first stirring rod and the second stirring rod. The cavity is connected to the air inlet groove through a first one-way valve, and the cavity is connected to the liquid storage cylinder through an air outlet groove, in which a second one-way valve is provided.

[0011] Preferably, a safety part is provided on the top side of the mounting plate, the safety part including two safety rings, the safety rings being rotatably connected to the mounting plate, and a safety rope being threaded through the two safety rings.

[0012] Preferably, a bucket is provided on one side of the mounting plate in the forward direction.

[0013] Furthermore, the present invention also provides a method for covering topsoil containing microorganisms for mine ecological restoration, comprising the following steps:

[0014] S1. Excavation on the slope;

[0015] S2. Compact the excavated soil in a direction perpendicular to the slope;

[0016] S3. Spread the microbial fertilizer into the excavated depression;

[0017] S4. Push the compacted soil mound above the slope into the depression.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. By setting up the push plate, the push plate can be inserted into the soil during the movement, and the soil can be piled up on the insertion plate during the return stroke, forming a pit. This facilitates the application of microbial fertilizer, and a soil layer with a higher soil density is formed on the lower side of the pit. This allows the microbial fertilizer to penetrate as much as possible in a direction perpendicular to the slope after being spread in the pit, avoiding the situation where the microbial fertilizer only acts on the soil surface due to the slope.

[0020] 2. By setting up the insertion rods and the drive mechanism, the push plate can move the soil clods on the soil surface to between the insertion rods during the movement process. When the push plate is inserted into the soil, the drive mechanism can drive the insertion rods to flip up, crushing the soil clods into smaller pieces, reducing hard soil clods, improving soil quality, and facilitating phytoremediation.

[0021] 3. The sliding mechanism prevents damage to the push plate and insertion plate when there are large, hard soil clods.

[0022] 4. The covering section allows the impeller to continuously impact the soil between the insertion plate and the push plate, breaking down hard soil clods and further improving soil quality, facilitating phytoremediation. The impeller can also push the soil protruding from the slope into the pit created in the previous process, covering the microbial fertilizer in the pit and preventing it from being exposed to the air and thus losing its nutrients.

[0023] 5. By setting up a water spray unit, after fertilization, the water spray unit sprays water on the soil above the microbial fertilizer, which facilitates the effect of the microbial fertilizer. At the same time, the use of a first booster pump to draw water from the outside reduces the space for water in the device, reduces the weight of the device, and increases the fertilization area of ​​the device.

[0024] 6. The spraying mechanism allows the microbial fertilizer in the storage tank to be sprayed out, and the rotation of the storage tank reduces liquid residue when the device is on a slope.

[0025] 7. By incorporating agitation and ventilation components, the rotation of the first agitator, second agitator, and scraper during operation stirs the microbial fertilizer in the storage tank, preventing sedimentation and inconsistent fertilizer concentration during prolonged operation. Simultaneously, the scraper contacts the inner wall of the storage tank, scraping it to prevent microbial fertilizer from adhering to the inner wall. Furthermore, it provides oxygenation to the storage tank, preventing oxygen deficiency and loss of activity in the microbial fertilizer during extended operation.

[0026] 8. The safety ring is designed so that when the mounting plate stops, the safety ring rotates and wraps around the safety rope, preventing the device from shaking and rolling down the slope when the pushing and inserting parts are working, thus improving the safety of the device.

[0055] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0056] See Figures 1 to 16 This invention discloses a surface soil covering device for mine ecological restoration containing microorganisms, comprising an insertion part 1, a pushing part 2 on one side of the insertion part 1, a covering part 3 on the other side of the insertion part 1, and a spreading part 4 on the side of the pushing part 2 away from the insertion part 1; the insertion part 1 includes an insertion plate 11 that moves vertically and can be inserted into the soil; the pushing part 2 includes a pushing plate 21 that moves in a straight line along the symmetrical line of the length direction of the insertion plate 11 and can also move vertically towards the insertion plate 11, thereby accumulating soil between the insertion plate 11 and the pushing plate 21; the covering part 3 includes a rotating impeller 31, the blades 311 of the impeller 31 that can push the accumulated soil away from the insertion plate 11; the insertion part 1, the pushing part 2, the covering part 3, and the spreading part 4 are all mounted on an installation plate 5 that moves in an intermittent straight line.

[0057] Specifically, during the ecological restoration of the mine slope soil, the installation plate 5 moves intermittently in a straight line along the mine slope. When the installation plate 5 stops moving, the push plate 21 moves in a straight line away from the insertion plate 11. After the push plate 21 moves a certain distance, it moves downward and inserts into the soil. At the same time, the insertion plate 11 moves downward and inserts into the soil. Then, the push plate 21 moves in a straight line closer to the insertion plate 11, piling up the soil between the insertion plate 11 and the push plate 21, and forming a pit where the push plate 21 passes. Then, the spreading part 4 is activated to spread microbial fertilizer into the pit. Then, the push plate 21 and the insertion plate 11 are retracted, and the installation plate 5 is moved so that the covering part 3 is in front of the soil pile generated in the previous working process. Then, the installation plate 5 is stopped, and the impeller 31 is rotated so that the blades 311 push the part of the soil pile protruding from the slope into the pit generated in the previous working process.

[0058] By setting the push plate 21, the push plate 21 can be inserted into the soil during the movement, and the soil can be piled up on the insertion plate 11 during the return stroke, forming a pit to facilitate the application of microbial fertilizer. A soil layer with a higher soil density is formed on the lower side of the pit, so that after the microbial fertilizer is spread in the pit, it can penetrate as much as possible in a direction perpendicular to the slope, avoiding the microbial fertilizer only acting on the soil surface due to the slope of the slope.

[0059] Furthermore, such as Figure 2 , 8 As shown, the insertion part 1 also includes a drive mechanism 13 disposed on the upper side of the insertion plate 11. The drive mechanism 13 includes two electromagnetic slide rails 131 symmetrically disposed on the bottom side of the mounting plate 5. A first electromagnetic slider 132 is slidably connected in each electromagnetic slide rail 131. The sliding direction of the first electromagnetic slider 132 in the electromagnetic slide rail 131 is parallel to the traveling direction of the mounting plate 5. A first electric push rod 133 is fixedly connected to the bottom end of each first electromagnetic slider 132. The bottom output end of the first electric push rod 133 is connected to the insertion plate 11. The bottom end of the insertion plate 11 is pointed. A pressure sensor is provided at the connection between the insertion plate 11 and the first electric push rod 133.

[0060] Specifically, when the insertion plate 11 needs to be inserted into the soil, the first electric actuator 133 is activated, causing the output end of the first electric actuator 133 to drive the insertion plate 11 into the soil; and when there are hard soil clods deep in the insertion position of the insertion plate 11, the pressure sensor detects a large pressure. In order to avoid damage to the insertion plate 11 and the first electric actuator 133, the insertion plate 11 is retracted, the first electromagnetic slider 132 is activated to slide in the first electromagnetic slide rail 131 to avoid the place with hard soil clods, and then it is re-inserted.

[0061] The first electric actuator 133 enables the insertion plate 11 to be inserted into the soil. The pressure sensor and drive mechanism 13 prevent damage to the insertion plate 11 and the first electric actuator 133 when the insertion plate 11 is inserted into the soil. The insertion plate 11 is pointed, which facilitates its insertion.

[0062] Furthermore, such as Figure 2 , 8 As shown, the pushing unit 2 also includes a second electromagnetic slider 22 that slides in the first electromagnetic slide rail 131. Each second electromagnetic slider 22 has a second electric push rod 23 fixedly connected to its bottom. The bottom output ends of the two second electric push rods are fixedly connected to the pushing plate 21, and the bottom end of the pushing plate 21 is pointed.

[0063] Specifically, when the push plate 21 needs to work, the second electromagnetic slider 22 is activated, causing the second electromagnetic slider 22 to slide in the electromagnetic slide rail 131. The second electromagnetic slider 22 drives the push plate 21 to move through the second electric push rod 23. When the second electromagnetic slider 22 moves to the end of the electromagnetic slide rail 131, the second electromagnetic slider 22 is stopped, and the second electric push rod 23 is activated to insert the push plate 21 into the soil.

[0064] like Figure 2 , 6 As shown, a breaking section 6 is provided on the side of the push plate 21 away from the insertion plate 11. The breaking section 6 includes an insertion rod 61, which includes a straight section 611 and an inclined section 612. The inclined section 612 is inclined from the straight section 611 toward the bottom surface. The straight section 611 is hinged to the push plate 21. A drive mechanism 62 for vertical movement is provided on the bottom side of the straight section 611.

[0065] Furthermore, such as Figure 2 , 6 As shown in Figure 15, the crushing part 6 also includes a first fixing plate 63 fixedly connected to the side of the push plate 21 away from the insertion plate 11. The insertion rods 61 are installed on the first fixing plate 63. The crushing part 6 includes twenty insertion rods 61 evenly spaced along the length of the first fixing plate 63. Each insertion rod 61 has two hinge plates 64 symmetrically arranged on both sides along the length of the first fixing plate 63. The insertion rods 61 are hinged to the two hinge plates 64. A torsion spring 65 is provided at the hinge point between the insertion rods 61 and the hinge plates 64. The drive mechanism 62 includes a second fixing plate 621 fixedly connected to the non-movable end of the second electric push rod 23. A drive plate 622 is provided on the bottom side of the straight section 611. The drive plate 622 and the second fixing plate 621 are connected by a pull rope 623, which is made of a rigid material.

[0066] Specifically, when the push plate 21 moves, it drives the insertion rod 61 to move. The inclined section 612 of the insertion rod 61 is inserted into the soil. During the movement of the push plate 21, the inclined section 612 moves the soil clods in the soil between the two insertion rods 61. As the push plate 21 moves, it moves the soil clods closer to the straight section 611. When the push plate 21 is inserted into the soil, due to the downward movement of the push plate 21, the straight section 611 is flipped upwards by the pull rope 623 and the second fixing plate 621.

[0067] By setting up the insertion rod 61 and the drive mechanism 62, the push plate 21 can move the soil clods on the surface of the soil to the space between the insertion rods 61 during the movement process. When the push plate 21 is inserted into the soil, the drive mechanism 62 can drive the insertion rod 61 to flip up, crush the soil clods into smaller pieces, reduce hard soil clods in the soil, improve soil quality, and facilitate phytoremediation.

[0068] like Figure 15 , 16 As shown, a sliding mechanism 12 is provided at the top of the insertion plate 11. The sliding mechanism 12 includes a slide rail 121, and a slider 122 is slidably connected in the slide rail 121. The slider 122 is fixedly connected to the insertion plate 11, and a first elastic element 123 is connected between the slider 122 and the slide rail 121.

[0069] Furthermore, the first elastic element 123 is a steel spring.

[0070] Specifically, when the device is not in operation, the slider 122 is located on the side of the slide rail 121 close to the push plate 21. When the push plate 21 pushes the soil toward the insertion plate 11, if there are large hard soil clods deep in the soil, in order to avoid the insertion plate 11 being subjected to excessive horizontal force and causing damage to the insertion plate 11, the insertion plate 11 can drive the slider 122 to slide in the slide rail 121 under the action of the hard soil clods, thereby increasing the distance between the push plate 21 and the insertion plate 11 when the push plate 21 is not in operation, thus protecting the device.

[0071] By setting up the sliding mechanism 12, damage to the pushing plate 21 and the insertion plate 11 can be avoided when there are large hard soil clods in the soil.

[0072] like Figure 10 , 13 As shown, the impeller 31 includes a mounting cylinder 312, the blade 311 includes a contact blade 3111, the mounting blade 3112 is slidably sleeved on the contact blade 3111, the mounting blade 3112 is fixedly connected to the mounting cylinder 312, a second elastic element 3113 is provided between the mounting blade 3112 and the contact blade 3111, and the contact blade 3111 can abut against the insertion plate 11 and the accumulated soil respectively.

[0073] Furthermore, such as Figure 10 , 13 As shown, the cover part 3 includes two third fixing plates 32 symmetrically fixedly connected to the bottom side of the mounting plate 5. The mounting cylinder 312 is rotatably connected in the third fixing plate 32. One end of the mounting cylinder 312 passes through the third fixing plate 32. The extended end of the mounting cylinder 312 is fixedly connected to the output end of the rotating motor. The rotating motor is fixedly connected to the third fixing plate 32. Six blades 311 are evenly arranged on the mounting cylinder 312 along the circumferential direction. The second elastic element 3113 is a steel spring.

[0074] Specifically, when the pusher plate 21 pushes the soil to the insertion plate 11, the insertion plate 11 moves a certain distance away from the pusher plate 21 under the pressure of the soil. The rotating motor is then activated, and its output drives the mounting cylinder 312 to rotate. The mounting cylinder 312 then drives the blades 311 to rotate, with the six blades 311 sequentially contacting the insertion plate 11. This causes the insertion plate 11 to continuously move closer to the pusher plate 21, continuously impacting the soil between the insertion plate 11 and the pusher plate 21, causing the hard soil clods to break down. During this impact process, the spreading mechanism is activated. The material spreading section 4 applies microbial fertilizer to the soil pit. After impacting for a period of time, the operation of the material spreading section 4 is stopped, and the first electric actuator 133 and the second electric actuator 23 are activated to retract the insertion plate 11 and the push plate 21 so that the bottom height of the insertion plate 11 and the push plate 21 is higher than the top height of the soil pile. Then, the mounting plate 5 is moved so that the covering part 3 is located in front of the soil pile generated in the previous working process. Then, the mounting plate 5 is stopped, and the impeller 31 is rotated so that the blades 311 push the part of the soil pile protruding from the slope into the soil pit generated in the previous working process.

[0075] By setting the covering part 3, the impeller 31 can continuously impact the soil between the insertion plate 11 and the push plate 21, causing the hard soil clods in the soil to break down, further improving the soil quality and facilitating phytoremediation. In addition, the impeller 31 can push the soil protruding from the slope into the pit generated in the previous working process, covering the microbial fertilizer in the pit and preventing the microbial fertilizer from being exposed to the air and thus losing its properties.

[0076] like Figure 4 , 14 As shown, a water spraying part 7 is provided on the side of the covering part 3 away from the insertion part 1. The water spraying part 7 includes a nozzle 71, which is connected to an external water source through a first booster pump 72.

[0077] Furthermore, the spreading section 4 contains a high concentration of liquid microbial fertilizer.

[0078] Specifically, when the impeller 31 pushes down the soil pile, the first booster pump 72 is started to spray water from the nozzle 71 to spray water on the soil pile covering the pit.

[0079] By setting up the water spraying unit 7, after fertilization, the water spraying unit 7 sprays water on the soil above the microbial fertilizer, which facilitates the effect of the microbial fertilizer. At the same time, the first booster pump 72 is used to draw water from the outside, which reduces the space for water in the device, reduces the weight of the device, and increases the fertilization area of ​​the device.

[0080] like Figure 4 , 8 As shown, the material spreading part 4 includes a rotatably mounted liquid storage cylinder 41 and two spraying mechanisms 42. The spraying mechanisms 42 are symmetrically arranged with respect to the center line of the length direction of the push plate 21. The spraying mechanisms 42 are connected to the bottom of the liquid storage cylinder 41 through a connecting pipe 43.

[0081] Furthermore, such as Figure 4 , 8 As shown, the spreading part 4 includes two fourth fixing plates 45 symmetrically fixedly connected to the bottom side of the mounting plate 5, and the liquid storage cylinder 41 is rotatably connected between the two fourth fixing plates 45; the spraying mechanism 42 includes a fixing rod 421 fixedly connected to the bottom side of the mounting plate 5, a nozzle 422 is provided at the bottom end of the fixing rod 421, and a second booster pump 423 is connected to the input end of the nozzle 422, and the input end of the second booster pump 423 is connected to the connecting pipe 43.

[0082] Specifically, when fertilization is needed, the second booster pump 423 is started, and the second booster pump 423 draws fertilizer from the storage tank 41 and sprays it out through the connecting pipe 43 and the nozzle 422.

[0083] The spray mechanism 42 allows the microbial fertilizer in the storage tank 41 to be sprayed out, and the rotation of the storage tank 41 reduces the amount of liquid residue in the storage tank 41 when the device is on a slope.

[0084] like Figure 4 , 9As shown in Figures 10, 11, and 12, the liquid storage cylinder 41 is equipped with a stirring and venting component 44. The stirring and venting component 44 includes a rotating shaft 441, which is rotatably mounted. A venting cylinder 442 is sleeved on the rotating shaft 441. An air inlet groove 443 is formed in the venting cylinder 442, communicating with the external space. A first stirring rod 444 is mounted on the venting cylinder 442, and a second stirring rod 445 is slidably mounted on the first stirring rod 444. A scraper 446 is provided on the second stirring rod 445. The first stirring rod 444 is slidably connected in the cavity 447 of the second stirring rod 445. A third elastic element 448 is provided between the first stirring rod 444 and the second stirring rod 445. The cavity 447 is connected to the air inlet groove 443 through a first one-way valve 449. The cavity 447 is connected to the liquid storage cylinder 41 through an air outlet groove 450. A second one-way valve 451 is provided in the air outlet groove 450.

[0085] Furthermore, the rotating shaft 441 passes through the central axis of the liquid storage cylinder 41 and is rotatably connected to the fourth fixed plate 45. One end of the rotating shaft 441 is fixedly connected to the output end of the variable speed motor. The variable speed motor is fixedly connected to the fourth fixed plate 45. The rotating shaft 441 is rotatably connected to the liquid storage cylinder 41. One end of the venting cylinder 442 passes through the liquid storage cylinder 41 and is rotatably connected to the liquid storage cylinder 41. The air inlet groove 443 is arranged along the axial direction of the venting cylinder 442. One end opening of the air inlet groove 443 is located on the extended end face of the venting cylinder 442. The third elastic element 448 is a steel spring. Gas can only enter the cavity 447 from the outside through the first one-way valve 449. Gas can only enter the outlet groove 450 from the cavity 447 through the second one-way valve 451. Twelve first stirring rods 444 are evenly arranged on the venting cylinder 442 along the axial direction. The ends of the twelve second stirring rods 445 are all fixedly connected to the scraper 446.

[0086] Specifically, when the device is in use, the variable speed motor is started, and the output end of the variable speed motor drives the rotating shaft 441 to rotate. The rotating shaft 441 drives the first stirring rod 444, the second stirring rod 445, and the scraper 446 to rotate through the venting cylinder 442, stirring the microbial fertilizer in the storage tank 41 to prevent the microbial fertilizer from settling during long-term operation of the device, which would result in inconsistent fertilizer concentrations when sprayed. Furthermore, the variable speed motor can intermittently accelerate. During acceleration, as the rotation speed of the venting cylinder 442 increases, the centrifugal force on the scraper 446 increases. Under the action of centrifugal force, the scraper 446 drives the second stirring rod 445 to move away from the venting cylinder 442, causing the cavity 447 to... As the volume increases and the air pressure decreases, the air in the air inlet 443 enters the cavity 447 through the first one-way valve 449. At the same time, the scraper 446 abuts against the inner wall of the liquid storage cylinder 41, scraping the inner wall of the liquid storage cylinder 41 to prevent the microbial fertilizer from adhering to the inner wall of the liquid storage cylinder 41. Then, the variable speed motor decelerates, and the second stirring rod 445 is reset under the action of the third elastic element 448, making the volume of the cavity 447 smaller. The volume in the cavity 447 is discharged through the second one-way valve 451 and the air outlet 450 and enters the liquid storage cylinder 41 to add gas and oxygen to the liquid storage cylinder 41, preventing the microbial fertilizer in the liquid storage cylinder 41 from lacking oxygen and losing its activity during long-term operation.

[0087] By incorporating the stirring and aeration component 44, the rotation of the first stirring rod 444, the second stirring rod 445, and the scraper 446 during operation stirs the microbial fertilizer in the storage tank 41, preventing sedimentation of the microbial fertilizer during prolonged operation and ensuring consistent fertilizer concentration. Simultaneously, the scraper 446 contacts the inner wall of the storage tank 41, scraping it to prevent microbial fertilizer from adhering to the inner wall and to provide oxygenation, thus preventing oxygen deficiency and loss of activity in the microbial fertilizer during prolonged operation.

[0088] like Figure 3 , 5 As shown, a safety part 8 is provided on the top side of the mounting plate 5. The safety part 8 includes two safety rings 81, which are rotatably connected to the mounting plate 5. A safety rope 9 is inserted through the two safety rings 81.

[0089] Furthermore, the safety unit 8 also includes a driven gear 82 sleeved on the bottom of the safety ring 81, and a motor frame 83 fixedly connected to the mounting plate 5. A safety motor 84 is fixedly connected to the motor frame 83, and a driving gear 85 is fixedly connected to the output end of the safety motor 84. The driving gear 85 meshes with the driven gear 84.

[0090] Specifically, when the mounting plate 5 is performing intermittent linear motion, when the mounting plate 5 stops, the safety motor 84 is started. The safety motor 84 drives the drive gear 85 to rotate, and the drive gear 85 drives the safety ring 81 to rotate through the driven gear 82.

[0091] By setting the safety ring 81, when the mounting plate 5 stops, the safety ring 81 rotates and wraps around the safety rope 9, preventing the device from shaking and rolling down the slope when the pushing part 2 and the insertion part 1 are working, thus improving the safety of the device.

[0092] like Figure 1 As shown, a bucket 10 is provided on one side of the mounting plate 5 in the forward direction.

[0093] The bucket 10 is designed to push away large, hard clods of soil along the movement path during use.

[0094] Furthermore, such as Figure 1 As shown, two fifth fixing plates are symmetrically arranged at the bottom of the mounting plate 5. The bottom ends of the two fifth fixing plates and the third fixing plate 32 are fixedly connected to the mounting frame. The bucket 10 is fixedly connected to the mounting frame. Four drive wheels are symmetrically arranged on both sides of the mounting frame.

[0095] The device is able to move by using drive wheels.
