Description

Technical Field

[0001] This invention relates to the field of alpine soil remediation technology, and more specifically, to a device for the restoration of degraded alpine meadows. Background Technology

[0002] Globally, the ecological restoration of degraded alpine meadows has become an urgent issue in the field of ecological engineering. These grasslands have suffered from increasingly severe soil degradation due to the long-term impact of multiple factors, including climate change, overgrazing, and human disturbance. In particular, soil compaction and reduced organic matter content have become two core obstacles hindering grassland ecological restoration.

[0003] Soil compaction is primarily the result of human factors such as overgrazing and continuous harvesting, combined with natural conditions like drought. The direct consequence of this soil condition is a significant increase in soil hardness, while simultaneously reducing water retention capacity and biological activity. Furthermore, the decrease in organic matter content caused by grassland degradation further exacerbates soil structure damage, making the soil even more compacted and hardened, severely impacting the health and sustainability of grassland ecosystems.

[0004] For the restoration of degraded alpine meadows, existing technologies typically involve planting grass seeds, hoping that grass growth will achieve the desired restoration effect. However, these technologies have significant shortcomings in implementation. First, soil tillage using agricultural equipment, such as rotary tillers or harrows, is usually required before planting grass seeds, and the use of this equipment inevitably damages the original grassland ecosystem. Second, existing agricultural equipment restoration methods follow the traditional process of tilling the soil first, then sowing seeds, and finally covering and compacting the soil. This method is not only time-consuming and labor-intensive but also inefficient, failing to meet the needs of large-scale grassland restoration. Summary of the Invention

[0005] This invention aims to address the aforementioned deficiencies by proposing a restoration device and method for degraded alpine meadows. The device is designed to meet the needs of ground ditching and grass seeding while ensuring that the original ecological environment of the grassland is not damaged during operation. Through meticulous design and optimization, this device can efficiently and accurately complete the restoration task.

[0017] Preferably, the outer end face of the support plate is further provided with a positioning component, which includes a sliding groove, a slider, a mounting rod, and a second roller. The sliding groove is rectangular and is opened along the length direction at the lower right side of the support plate.

[0018] The installation box is equipped with at least two air pumps, and the air pumps can push the second roller to move when inflated.

[0019] Preferably, the upper and lower ends of the slide groove are respectively connected by a first connecting groove and a second connecting groove.

[0021] Preferably, the detection assembly includes a sleeve, a first spring, a support rod, and a first roller. The sleeve is a cylindrical tube and is fixedly installed vertically on the bottom end face of the lifting plate. The support rod is slidably installed inside the sleeve, and its lower end extends downward toward the sleeve. The first spring is installed at the top of the inside of the sleeve, and its lower end is fixedly connected to the top end face of the support rod. The first roller is rotatably installed at the lower end of the support rod and is in contact with the grass. The first roller is positioned opposite to the cutting saw blade.

[0022] Preferably, the inner wall of the sleeve is vertically connected to the outer side with a slot of elongated structure. One end of the support rod facing the slot is fixedly provided with an extension rod in the horizontal direction. One end of the extension rod passes through the slot, and a rack is fixedly provided in the vertical direction at the outer end of the extension rod. The rack is elongated, and a mounting box is fixedly provided on the left side of the rack along the outer end face of the sleeve. A first connecting gear is rotatably provided in the mounting box. A second connecting gear is rotatably provided on the lower left side of the first connecting gear along the inner end face of the mounting box.

[0024] Preferably, the repair box has a first and a second elongated material bin independently located on the top right side. The first and second material bins contain different seeds, and several discharge pipes are connected to the bottom of both the first and second material bins. The discharge pipes are arranged opposite to the corresponding cutting components. A solenoid valve is provided at the outlet end of each discharge pipe. The solenoid valve is connected to a microcontroller. In use, the solenoid valve can control whether the discharge pipe is opened or closed.

[0025] Preferably, the rear of the repair box is provided with a row of pressure devices along the front-to-back direction.

[0026] A method for restoring degraded alpine meadows, which utilizes the aforementioned equipment for restoring degraded alpine meadows, includes:

[0027] S1: First, prepare the grass seeds and fertilizer according to the predetermined mass ratio. Then, allocate the grass seeds and fertilizer according to two different ratios. Then, mix the allocated grass seeds and fertilizer separately. After mixing, two grass seed mixtures with different ratios are obtained.

[0028] S2: Put the first type of grass seed mixture and the second type of grass seed mixture into the first or second hopper respectively and wait for use;

[0029] S3: Drive the vehicle to the grass to be cut, then move the repair box along the lateral direction on the grass. When moving, first start the cutting component to cut. During the cutting, the grass surface can be formed into grooves. Then, the solenoid valve controls the first hopper to discharge the grass. When discharging, the grass seed mixture can fall into the lateral grooves correctly. The compactor at the rear of the repair box can cover the seeds in the lateral grooves with soil and compact them.

[0030] S4: When the cutting assembly is in operation, the pressure sensor is activated to monitor the unevenness of the ground. When the pressure sensor detects changes in the ground, the controller controls whether the electromagnetic clutch is disconnected or reconnected to allow the cutting assembly to continue normal cutting operations.

[0031] S5: After the cutting component completes the transverse cutting of the grass, the vehicle body is driven back to the initial cutting point of the grass, and then a second cutting is performed along the longitudinal direction of the grass. Before the second cutting, the push block can be driven by the microcontroller and air pump to move the second roller, so that the cutting depth of the cutting saw blade on the grass can be adjusted.

[0032] S6: When the vehicle body drives the cutting component to make longitudinal cuts in the grass, the second hopper is controlled by the solenoid valve to discharge the grass seed mixture. The grass seed mixture can fall into the longitudinal trench correctly during discharge. Then, the longitudinal trench is covered with soil and compacted by the compactor.

[0033] The beneficial effects of this invention are as follows:

[0034] 1. This solution incorporates multiple independent cutting components within the restoration box. Each component consists of a dedicated support plate and a corresponding cutting saw blade. The design of these cutting components breaks through traditional farming methods, allowing for the direct and effective cutting of hard grassland to create furrows for sowing. In this way, the hopper can directly sow seeds into these newly formed furrows. Compared with the traditional method of tilling the land before sowing, this solution not only improves sowing efficiency and reduces disturbance to the grassland ecosystem, but also significantly enhances the convenience and overall efficiency of grassland restoration work. In addition, a second spring is installed at the top of the cutting component, enabling the component to adapt to the undulations of the grassland and maintain the continuous and stable operation of the cutting saw blade.

[0035] 2. This invention cleverly integrates a power component and a transmission component in front of the cutting assembly. The power component consists of a motor, a drive rod, and a drive gear, ensuring the synchronous rotation of all cutting saw blades. The transmission component includes a second fixed block, a driven rod, a driven gear, and an electromagnetic clutch. The intelligent control of the electromagnetic clutch provides flexible connection and disconnection functions for the cutting saw blades, optimizes the equipment's adaptability to complex terrain, and makes the cutting operation more precise and efficient.

[0036] 3. This invention incorporates a second roller on the cutting assembly that cooperates with the cutting saw blade. This roller can flexibly slide on the outer end face of the cutting assembly according to actual needs. In actual operation, when the second roller contacts the grass surface, it provides stable reverse support force, offering necessary support and balance for the cutting saw blade. This ingenious design ensures the uniformity of the cutting depth, thereby significantly improving the accuracy of sowing. Furthermore, since the second roller can adjust its position after sliding, the cutting depth of the cutting saw blade on the grass also changes when the roller's position changes. This allows for adjustment of the optimal sowing depth according to planting requirements. Attached Figure Description

[0054] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] As attached Figure 1 To be continued Figure 8 The diagram shows a restoration device for degraded alpine meadows, comprising a vehicle body 1, a bucket 11 located at the front end of the vehicle body 1, and a restoration box 2 located at the rear end of the vehicle body 1 via a connecting frame. The restoration box 2 has several wheels 21 rotatably mounted along its outer end face, with each wheel 21 contacting the ground. During use, the vehicle body 1 can tow the restoration box 2 along the connecting frame, while the bucket 11 can remove rocks from the ground in front. The restoration box 2 has a receiving space 26 extending from its interior to its bottom end face. At least four cylinders 28 are vertically mounted above the receiving space 26 along its top surface, with the telescopic rods of the cylinders 28 extending into the receiving space 26. A lifting plate 27 is located at the top of the interior of the receiving space 26, with its top connected to the telescopic rods of the cylinders 28, allowing the cylinders 28 to move the lifting plate 27 up and down.

[0056] Meanwhile, a mounting plate 5 is fixedly installed in the middle of the bottom of the lifting plate 27, and several independent cutting components are spaced apart along the front-to-back direction on the bottom of the mounting plate 5. These cutting components are used to cut the relatively hard grass (straw layer) in a straight line, so that it can form grooves. On the bottom left and bottom right sides of the lifting plate 27, several independent detection components are spaced apart and distributed. These detection components are set in correspondence with the cutting components. During use, the detection components can detect the unevenness of the grass (straw layer). If the grass has depressions or bumps, the cutting components can automatically adjust to follow the terrain, thereby ensuring that the cutting components can cut the depressions or bumps in the ground.

[0057] Additionally, a first hopper 22 and a second hopper 23, each with an elongated structure, are independently located on the top right side of the repair box 2. The first hopper 22 and the second hopper 23 contain different types of seeds. Several discharge pipes 24 are connected to the bottom of both hoppers 22 and 23, and these discharge pipes 24 are positioned opposite to the corresponding cutting components. This design allows the grass seeds falling from the discharge pipes 24 to directly enter the trenches formed after the cutting components complete a straight cut on the ground, thus distributing the grass seeds. Simultaneously, a solenoid valve 25 is installed at the outlet end of the discharge pipe 24. This solenoid valve 25 controls whether the discharge pipe 24 is opened or closed, thereby controlling the discharge of grass seeds from the discharge pipe 24.

[0058] Furthermore, a row of compactors 9 is installed at the rear of the repair box 2 along the front-to-back direction. These compactors 9 can be conveniently suspended at the rear of the repair box 2 using ropes or special brackets. During operation, they can effectively cover the grass seeds in the trenches with soil. Specifically, when the grass seeds are placed into the trenches formed by the cutting components through the discharge pipe 24, the compactors 9 at the rear of the repair box 2 play their role, pushing the loose soil on the ground—which is naturally formed during the cutting process—into the trenches, achieving rapid burial of the grass seeds. The compactors 9 can be made of chains or tires. During installation, one end of the chain or tire can be fixed and suspended, while the other end remains in contact with the ground. As the repair box 2 moves forward, the compactors 9 perform the soil covering operation, ensuring that the grass seeds are evenly and tightly covered under the soil.

[0059] like Figures 2 to 4 As shown, in this embodiment, the cutting assembly includes a third fixing block 6, a first through hole 61, a support plate 62, a second through hole 63, a connecting sleeve 64, a rotating rod 66, a cutting saw blade 67, and a second spring 691. The third fixing block 6 is fixedly connected to the bottom end face of the mounting plate 5. The first through hole 61 is opened through the left and right sides of the third fixing block 6, and the second through hole 63 is opened through the left and right sides above the support plate 62. The connecting sleeve 64 is in the shape of a round tube, with one end fixedly connected to the inside of the second through hole 63, and the other end rotatably connected to the inner wall of the first through hole 61. In this way, the support plate 62 is allowed to rotate through the connecting sleeve 64 and the first through hole 61 during use.

[0060] The rotating rod 66 is rotatably positioned on the lower left side of the support plate 62, while the cutting saw blade 67 is connected to the outer end face of the rotating rod 66. Furthermore, the outer edge of the cutting saw blade 67 extends beyond the lower end of the support plate 62. This design ensures that the cutting saw blade 67 is not interfered with by the support plate 62 when cutting the grass (turf). For example, when the cutting saw blade 67 cuts into the grass, the support plate 62 can be kept at a safe distance, thus ensuring smooth cutting action.

[0061] Meanwhile, a second spring 691 is installed on the upper part of the outer wall of the support plate 62 along the inclined direction. The two ends of the second spring 691 are connected to the bottom end faces of the support plate 62 and the mounting plate 5, respectively. In use, the second spring 691 can apply a downward thrust to the support plate 62. This thrust can help the support plate 62 change with the terrain, thereby allowing the cutting saw blade 67 to cut grass (sore layers) of different terrains. For example, when encountering a depression in the grass (sore layer), the elasticity of the second spring 691 causes the support plate 62 to drive the cutting saw blade 67 to rotate clockwise, allowing the cutting surface to make stable contact with the depression. Similarly, when encountering a raised area of ​​grass, resistance can be applied to the support plate 62, causing the support plate 62 to drive the cutting saw blade 67 to rotate counterclockwise, allowing the cutting saw blade 67 to make stable contact with the raised area.

[0062] Furthermore, a bearing 65 is fixedly installed on the inner wall of the connecting sleeve 64, and a connecting rod 651 is fixedly installed on the inner ring of the bearing 65. One end of the connecting rod 651 extends to the left side of the support plate 62, and the other end extends to the right side of the third fixing block 6. This design allows the connecting rod 651 to rotate within the connecting sleeve 64 via the bearing 65, and its friction during rotation is less than the rotational friction between the connecting sleeve 64 and the first through hole 61. The advantage of this is that when the connecting rod 651 rotates alone, due to the small friction, it will not drive the support plate 62 to move together during rotation. This ensures the extension stability of the support plate 62, enabling the cutting saw blade 67 to rotate stably.

[0063] Furthermore, both the end of the connecting rod 651 facing the support plate 62 and the outer end face of the rotating rod 66 are provided with transmission wheels 68, and a transmission belt 69 is adapted to be provided on the outer end face of the transmission wheel 68. In this way, when the connecting rod 651 rotates, the cutting saw blade 67 can be driven to perform cutting operations through the combination of the transmission wheel 68 and the transmission belt 69. It should be noted that the transmission belt 69 and the transmission wheel 68 can be made of sprockets and chains.

[0064] Based on the above embodiments, such as Figures 2 to 4As shown, a corresponding transmission assembly is also provided on the right side of the cutting assembly. This transmission assembly includes a second fixed block 51, a driven rod 52, a driven gear 53, and an electromagnetic clutch 54. The second fixed block 51 is connected to the bottom end face of the mounting plate 5, and the second fixed block 51 is arranged opposite to the third fixed block 6. The driven rod 52 is located on the opposite side of the docking rod 651, and one end of the driven rod 52 is rotatably connected to the second fixed block 51. The electromagnetic clutch 54 is then located between the docking rod 651 and the driven rod 52. This design allows the electromagnetic clutch 54 to control the disconnection or connection between the docking rod 651 and the driven rod 52. When disconnected, the driven rod 52 cannot drive the docking rod 651 to rotate; when connected, the driven rod 52 can drive the docking rod 651 to move together. The driven gear 53 is located at the middle of the outer wall of the driven rod 52. In use, the driven gear 53 can drive the driven rod 52 to rotate.

[0065] Furthermore, to facilitate the rotation of these transmission components, a power assembly is provided along the lower surface of the lifting plate 27 in front of the transmission components. This power assembly includes a first fixed block 4, a motor 41, a drive rod 42, and a drive gear 43. At least two first fixed blocks 4 are provided, and they are fixedly installed along the lower surface of the lifting plate 27 in the front-back direction. One motor 41 is provided and is fixedly installed on the first fixed block 4 by a bracket. The drive rod 42 is rotatably connected to the left and right ends of the first fixed block 4, and one end of the drive rod 42 is also connected to the drive shaft of the motor 41. The drive gear 43 is set according to the number of driven gears 53. During installation, the drive gear 43 is fixedly installed along the outer wall of the drive rod 42, and the drive gear 43 is also meshed with the corresponding driven gear 53. In operation, the motor 41 drives the drive rod 42 to rotate. This rotation allows multiple drive gears 43 on the drive rod 42 to contact their corresponding driven gears 53. This contact drives multiple cutting components to move together, simultaneously cutting the grass (grass mat) and creating multiple furrows. Furthermore, the electromagnetic clutch 54 disconnects the driven rod 52 from the connecting rod 651 when the cutting components encounter uneven terrain. This disconnection prevents the connecting rod 651 from interfering with the rotation of the driven rod 52 as the cutting components extend and rotate due to the terrain, ensuring stable rotation of the drive rod 42.

[0066] like Figure 2 and Figure 5As shown, in this embodiment, the positioning component includes a sliding groove 7, a slider 71, a mounting rod 72, and a second roller 73. The sliding groove 7 is rectangular and is located on the lower right side of the support plate 62 along its length. The lower end of the sliding groove 7 is also positioned opposite to the mounting position of the rotating rod 66. The slider 71 is fitted and slidably disposed within the sliding groove 7, while the mounting rod 72 is fixedly connected to the center end of the slider 71. The second roller 73 is rotatably disposed on the outer end face of the mounting rod 72. This design allows the slider 71 to drive the second roller 73 to slide within the sliding groove 7. When sliding upwards, the second roller 73 can move away from the relative position of the rotating rod 66; when sliding downwards, the second roller 73 can be positioned opposite to the mounting position of the rotating rod 66.

[0067] Meanwhile, the second roller 73 is located on the back of the cutting saw blade 67, and the diameter of the second roller 73 is smaller than the diameter of the cutting saw blade 67. The outer edge of the second roller 73 extends beyond the lower end of the support plate 62. This arrangement allows the second roller 73 to apply necessary reverse resistance to the support plate 62 when the saw blade cuts into the grass. This not only prevents uncontrolled cutting depth due to excessive force of the second spring 691, but also achieves precise cutting to a predetermined depth of grass through the synergistic effect of the second roller 73 and the saw blade. That is, since the second roller 73 rolls on the grass, and the saw blade cuts into the grass, the depth to which the saw blade cuts into the grass when the second roller 73 contacts the grass is its cutting depth.

[0068] On the other hand, since the second roller 73 can apply opposite resistance to the support plate 62, when the elastic force of the second spring 691 and the resistance of the second roller 73 are both applied to the support plate 62, the rotating support plate 62 can be kept in balance, thus ensuring the cutting stability of the cutting saw blade 67.

[0069] Based on the above embodiments, such as Figure 6 and Figure 7 As shown, a first connecting groove 74 and a second connecting groove 75 are respectively connected to the upper and lower ends of the slide groove 7. Both the first connecting groove 74 and the second connecting groove 75 are elongated structures, and the internal width of the first connecting groove 74 and the second connecting groove 75 is smaller than the internal width of the slide groove 7. This design ensures that when the slider 71 in the slide groove 7 slides, it will not enter the two connecting grooves mentioned above.

[0070] Meanwhile, a first push block 741 and a second push block 751 are slidably disposed in the first connecting groove 74 and the second connecting groove 75, respectively, and one end of the first push block 741 and the second push block 751 extends into the sliding groove 7. In use, the first push block 741 or the second push block 751 can be pushed individually to move the slider 71 in the sliding groove 7. For example, when the second push block 751 is pushed to move into the sliding groove 7, the slider 71 can drive the second roller 73 to slide above the support plate 62. After sliding, the relative distance between the second roller 73 and the cutting saw blade 67, that is, the distance between the bottom of the second roller 73 and the bottom of the cutting saw blade 67, can be changed. When the position of the second roller 73 is adjusted, the depth of the cutting edge into the grass (straw layer) can be changed, thereby achieving precise adjustment of the cutting depth.

[0071] Furthermore, two separate air supply pipes, a first air supply pipe 76 and a second air supply pipe 77, are respectively provided inside the support plate 62. The first air supply pipe 76 and the second air supply pipe 77 are supplied with air by two separate air pumps 81. The other end of the first air supply pipe 76 communicates with the inside of the first connecting groove 74, while the other end of the second air supply pipe 77 communicates with the inside of the second connecting groove 75. In use, the two separate air pumps 81 can supply or release air to the first air supply pipe 76 and the second air supply pipe 77. When the second connecting groove 75 is inflated, the gas pressure inside increases, causing the second pusher block 751 to exert an upward pushing force on the slider 71, causing the slider 71 to move upward. At the same time, when the first connecting groove 74 is deflated, the internal pressure decreases, and the first pusher block 741 can completely retract under the push of the slider 71, providing space for the slider 71 to move upward.

[0072] Furthermore, the mounting box is equipped with at least two air pumps 81, one of which is connected to the first air supply pipe 76 via an air pipe connector, while the other air pump 81 is also connected to the second air supply pipe 77 via an air pipe connector. This design allows for simultaneous adjustment of the second roller 73 on the cutting assembly, which in turn allows for adjustments to the cutting depth of the cutting saw blades 67.

[0073] like Figure 2 and Figure 5As shown, in this embodiment, the detection component includes a sleeve 3, a first spring 31, a support rod 32, and a first roller 33. The sleeve 3 has a cylindrical structure and is fixedly installed vertically on the bottom end face of the lifting plate 27. The support rod 32 is slidably installed inside the sleeve 3, and the lower end of the support rod 32 extends downwards from the sleeve 3. The first spring 31 is installed at the top end inside the sleeve 3, and the lower end of the first spring 31 is fixedly connected to the top end face of the support rod 32. The first roller 33 is rotatably installed at the lower end of the support rod 32 and is in contact with the grass (straw mat). In use, the repair box 2 is allowed to drive the first roller 33 to roll on the grass (straw mat). During the rolling process, the ground may encounter depressions or protrusions. Therefore, when the first roller 33 rolls to these terrain features, it can drive the support rod 32 and the first roller 33 to move under the action of the first spring 31, thus reflecting the terrain features of the grass.

[0074] Furthermore, the first roller 33 is positioned opposite to the cutting saw blade 67. This design allows the first roller 33 to first contact the concave or convex grass surface when the repair box 2 drives the first roller 33 and the second roller 73 to roll. Once the first roller 33 senses the change in the grass surface, it is convenient to temporarily disconnect the rotating cutting component from the electromagnetic clutch 54.

[0075] Based on the above embodiments, such as Figure 2 and Figure 5 As shown, a long, narrow slot 34 is vertically connected from the inner wall to the outer side of the sleeve 3. An extension rod 35 is fixed horizontally at one end of the support rod 32 facing the slot 34. One end of the extension rod 35 passes through the slot 34, and a rack 36 is vertically fixed at the outer end of the extension rod 35. The rack 36 is long and narrow. Simultaneously, a mounting box 37 is fixedly installed on the left side of the rack 36 along the outer end face of the sleeve 3. A first connecting gear 371 is rotatably mounted inside the mounting box 37. A second connecting gear 372 is rotatably mounted on the lower left side of the first connecting gear 371 along the inner end face of the mounting box 37. The first connecting gear 371 is a large gear, and the second connecting gear 372 is a small gear, and the first connecting gear 371 and the second connecting gear 372 are meshed together. This design allows the rack 36 to rotate when the support rod 32 drives the rack 36 to move up and down, which in turn drives the first connecting gear 371 to rotate. The first connecting gear 371 then drives the second connecting gear 372 to rotate.

[0076] Subsequently, an extension shaft 373 is fixedly installed at the central shaft of the second connecting gear 372. A disc-shaped rotating block 374 is fixedly installed at the front end of the extension shaft 373. Several arc-shaped protrusions 375 are distributed on the outer end face of the rotating block 374. A pressure sensor 38 is arranged horizontally on the left side of the protrusion 375. The pressure sensor 38 is a spring-type pressure sensor 38. In the initial state, the contact end of the pressure sensor 38 is close to the outer end face of the rotating block 374. When the second connecting gear 372 drives the extension shaft 373 to rotate, the protrusions 375 on the rotating block 374 can contact the pressure sensor 38, thus triggering the pressure sensor 38 normally. After triggering, it indicates that there is a depression or bulge in the grass (terry layer) in that direction, which can remind the cutting component at the corresponding position. After the reminder, the rotating cutting component can be disconnected.

[0077] like Figure 8 As shown, in this embodiment, the repair box 2 is also equipped with a control component, which includes a microcontroller 8 and an electronic timer 82. The electronic timer 82 is connected to the microcontroller 8, while the solenoid valve 25, cylinder 28, pressure sensor 38, electromagnetic clutch 54, motor 41, and air pump 81 are all connected to the microcontroller 8. In use, the electronic timer 82 can provide timing functionality to the microcontroller 8. When the first roller 33 encounters a protrusion or depression on the grass (straw mat) and moves up and down accordingly, its support rod 32 immediately responds to the change in terrain. This movement directly triggers the associated pressure sensor 38, which then converts the terrain change signal into an electrical signal and transmits it to the microcontroller 8 and the electronic timer 82.

[0078] Upon receiving the signal, the microcontroller 8, based on the timing information provided by the electronic timer 82, issues a cutting command to the designated electromagnetic clutch 54 according to preset time parameters. During the cutting process, the cutting assembly adapts to changes in terrain by utilizing the thrust of the second spring 691 or the natural pushing force of the terrain protrusion. Once the preset cutting time is reached, the electronic timer 82 sends a signal to the microcontroller 8, triggering the electromagnetic clutch 54 to re-establish rotational connection with the cutting assembly. This allows the cutting assembly to return to normal operation and continue ground cutting.

[0079] This embodiment also provides a method for soil remediation using the aforementioned equipment for remediating degraded alpine meadows, the method comprising:

[0080] S1: First, prepare the grass seeds and fertilizer according to the predetermined mass ratio. Then, allocate the grass seeds and fertilizer according to two different ratios. Then, mix the allocated grass seeds and fertilizer separately. After mixing, two grass seed mixtures with different ratios are obtained.

[0081] S2: Put the first type of grass seed mixture and the second type of grass seed mixture into the first hopper 22 or the second hopper 23 respectively for use;

[0082] S3: Drive vehicle 1 to the grass (grass mat) to be cut, then drive repair box 2 and move it in the lateral direction on the grass. When moving, first start the cutting component to cut. When cutting, the grass ground can form grooves. Then, the solenoid valve 25 controls the first hopper 22 to discharge the material. When discharging, the grass seed mixture can fall into the lateral grooves correctly. The compactor 9 at the rear of repair box 2 can cover the seeds in the lateral grooves with soil and compact them.

[0083] S4: When the cutting assembly is in operation, the pressure sensor 38 is activated to monitor the unevenness of the ground. When the pressure sensor 38 senses a change in the ground, the controller controls the electromagnetic clutch 54 to disconnect or reconnect the cutting assembly to carry out normal cutting operations.

[0084] S5: After the cutting assembly completes the transverse cut of the grass (straw layer), the vehicle body 1 is driven back to the initial cutting point of the grass (straw layer), and then a secondary cut is performed along the longitudinal direction of the grass (straw layer). Before the secondary cut, the push block can be moved by the microcontroller 8 and the air pump 81 to move the second roller 73, thus adjusting the cutting depth of the cutting saw blade 67 on the grass (straw layer).

[0085] S6: When the vehicle body 1 drives the cutting component to make longitudinal cuts in the grass (grass mat layer), the solenoid valve 25 controls the second hopper 23 to discharge the grass seed mixture. The grass seed mixture can fall into the longitudinal trench correctly during the discharge. Then, the compactor 9 covers the longitudinal trench with soil and compacts it. After compaction, the planting of the grass seed mixture is completed.
