Description

Technical Field

[0001] The present invention belongs to the field of slope protection, and in particular relates to an ecological restoration device and method for effectively stripping and restoring a grass felt layer on an alpine meadow. Background Art

[0002] Alpine meadow grasslands are one of the primary vegetation types on the Qinghai-Tibet Plateau, particularly crucial for the protection of the "China Water Tower" in the Sanjiangyuan region, which accounts for 65% of its total area. They are primarily distributed in areas above 3,000 meters above sea level, characterized by cooler temperatures, higher rainfall, and fertile soil. They are characterized by lush vegetation, including grasses and chrysanthemums, and relatively high humidity. Their root systems are well-developed, forming a "felt layer" typically 10-15 cm thick. These herbaceous plants stabilize the soil through their roots, reducing wind and water erosion, helping to maintain soil fertility and water balance, maintaining soil stability and preventing water loss. These herbaceous plants play a vital role in water conservation and provide food and habitat for wildlife. Furthermore, alpine meadow grasslands absorb and store atmospheric carbon dioxide, contributing to climate change mitigation. However, alpine meadow ecosystems are extremely fragile, and damage is irreversible, with some vegetation requiring hundreds of years to recover.

[0003] When carrying out road construction and other engineering construction, it is necessary to first cut the meadow and preserve the cut turf as much as possible to maintain its ecological characteristics. After the construction is completed, the temporary land for construction will be sorted out, and the stripped meadow grass layer will be restored to carry out ecological restoration of the construction site. The original ecological characteristics of the alpine meadow will be retained to the greatest extent and the quality of ecological restoration will be improved.

[0014] The method for using the ecological restoration equipment for effectively stripping and restoring the alpine meadow grass felt layer includes the following steps: S1: When cutting the meadow grass felt layer in a flat area, the driving vehicle body drives the whole vehicle forward, first pre-cutting the predetermined area, digging a groove with a depth of 10-15 cm, so as to guide the cutting knife to accurately cut the turf along the predetermined depth, and the driving motor drives the roller blade to perform longitudinal cutting first, and then the set cutting knife is used to cut the meadow grass felt layer horizontally. As it continues to move forward, the lifting part will lift the cut meadow grass felt layer. At this time, the meadow grass felt layer contacts the upper surface of the first transmission belt, and the cut meadow grass felt layer is transported to the first turf conveyor belt under the action of the first transmission belt. During the cutting process, the meadow grass felt layer will be cut off by the set cutting machine every time a certain distance is cut, thereby dividing the meadow grass felt layer into multiple sections, so that the staff can stack the meadow grass felt layer. The first transmission belt will transport the meadow grass felt layer to the first turf conveyor belt. As the first turf conveyor belt transports the meadow grass felt layer to the driving vehicle body, the staff will take out the cut meadow grass felt layer from the first turf conveyor belt and sort and stack it. S2: When the third motor drives the first pulley to rotate clockwise via the rotating shaft, the rotating shaft of the third motor drives the first direction-adjusting gear to rotate in the same direction via the second transmission belt, so that the first driven gear rotates counterclockwise under the meshing action, and then the corresponding pressure roller rotates counterclockwise, thereby assisting in pushing the meadow grass felt layer on the first transmission belt and squeezing the meadow grass felt layer to compact it; S3: When cutting the meadow on the ramp, the second motor is used to drive the docking arm to rotate, thereby changing the angles of the slave arm, the docking arm, the first turf support plate and the cutting knife. The first hydraulic valve is used to change the distance between the docking arm and the slave arm to prevent the first turf support plate from interfering with the first turf conveyor belt during rotation adjustment. The first motor drives the screw to rotate through the rotating shaft, and the motor base slides on the driving vehicle body under the meshing action, thereby changing the distance between the slave arm, the docking arm, the first turf support plate and the cutting knife and the ramp. Under the action of the first motor and the second motor, the slave arm, the docking arm, the first turf support plate and the cutting knife are quickly moved to the ramp. When fine-tuning, the second hydraulic valve drives the docking support seat to move slightly through its telescopic end, and the sixth motor drives the active adjustment gear to rotate through the rotating shaft. The third driven gear is driven by the lower part to rotate, and the third driven gear drives the docking rod to rotate, and the docking rod drives the two first connecting members to rotate, and the two first connecting members drive the first turf supporting plate to rotate. At the same time, the two first connecting members drive the cutting knife to rotate through the blade fixing plate, so that the first turf supporting plate and the cutting knife rotate, thereby improving the fit between the first turf supporting plate and the cutting knife and the ramp. In the process of cutting the meadow on the ramp, the meadow turf felt layer is cut off by the cutting machine after each cutting a certain distance, and then the first turf supporting plate and the cutting knife are reset with the cooperation of the first motor, the second motor, the first hydraulic pressure, the second hydraulic pressure and the sixth motor, so that the cut meadow turf felt layer is transported back to the first turf conveyor belt for further transmission and leveling. Without resetting, the staff manually puts the cut and compacted meadow turf felt layer onto the first turf conveyor belt for transmission and leveling; S4: When laying a meadow grass blanket layer in a flat area, the first turf support plate and the cutting blade are reset, the docking support base is lifted by the second hydraulic device, and the cutting blade is separated from the ground, and the driving vehicle body is moved to the ground where it needs to be returned; S5: The staff places the leveled meadow grass felt layer on the second turf conveyor belt. The fifth motor drives the second turf conveyor belt to transport the meadow grass felt layer to the third transmission belt. The lower end of the leveling unit contacts the ground. When the driving vehicle body moves forward, the leveling unit squeezes and levels the land to be returned. S6: When laying meadow grass on the ramp, after the second turf conveyor belt transports the meadow grass felt layer to the third transmission belt, the position of the second turf support plate and the leveling part can be adjusted with the cooperation of the adjustment structure to carry out laying. During the adjustment process, the fourth motor stops working. After the adjustment of the adjustment structure is completed, the fourth motor starts working, thereby driving the third transmission belt to deliver the meadow grass felt layer, so that the meadow grass felt layer is laid on the ramp; S7: During the laying process, the staff inserts the magnetic head of the multi-pressure rod turf fixing nail into the extrusion port along the slot. Under the action of the opposite magnetic poles of the magnetic head and the magnetic thimble, the top of the magnetic head will be magnetically attracted to the bottom of the magnetic thimble. When fixing the meadow grass felt layer, the telescopic end of the telescopic gas rod presses the thimble plate downward, and the thimble plate presses the magnetic head downward through the magnetic thimble, thereby inserting the nail body at the bottom of the magnetic head into the meadow grass felt layer and the soil. As the nail body penetrates, the friction between the nail body and the meadow grass felt layer and the soil increases. After fixing, the telescopic end of the telescopic gas rod pulls the thimble plate upward to reset it, and the thimble plate drives the magnetic thimble to move upward and reset. During the resetting process of the magnetic thimble, the friction between the nail body and the meadow grass felt layer and the soil increases, and the meadow grass felt layer and the soil will firmly fix the nail body, so that the magnetic thimble will separate from the magnetic head when it moves upward and resets, thereby leaving the multi-pressure rod turf fixing nail on the meadow grass felt layer, so that the meadow grass felt layer and the soil are fixed; S8: After the ramp is laid, the second turf pallet is reset through the adjustment structure, and the meadow turf layer is transported to the third transmission belt through the second turf conveyor belt again for the next laying. Without resetting, the staff can manually place the cut and compacted meadow turf layer on the third transmission belt for the next laying.

[0015] (3) Beneficial effects Compared with the prior art, the present invention has the following beneficial effects: First, in the present invention, when making adjustments, the power arm, docking arm, first turf support plate and cutting blade are quickly moved onto the ramp through the adjustment structure, and then the first turf support plate and cutting blade are fine-tuned to improve the accuracy of the fit with the slope surface; Specifically, the second motor is used to drive the docking arm to rotate, thereby changing the angles of the slave arm, the docking arm, the first turf support plate and the cutting knife. Under the cooperation of the first motor and the screw, the motor base slides on the driving vehicle body, thereby changing the distance between the slave arm, the docking arm, the first turf support plate and the cutting knife and the ramp. Under the cooperation of the first motor and the second motor, the slave arm, the docking arm, the first turf support plate and the cutting knife are quickly moved onto the ramp. When fine-tuning, the second hydraulic cylinder drives the docking support seat to move slightly through its telescopic end, and the sixth motor drives the active adjustment gear to rotate through the rotating shaft, and drives the third driven gear to rotate under the action of meshing, and the third driven gear drives the docking rod to rotate, and the docking rod drives the two first connecting members to rotate, and the two first connecting members drive the first turf support plate to rotate. At the same time, the two first connecting members drive the cutting knife to rotate through the blade fixing plate, thereby rotating the first turf support plate and the cutting knife, thereby improving the fit of the first turf support plate and the cutting knife to the ramp.

[0016] 2. In the present invention, when the third motor drives the first pulley to rotate clockwise through the rotating shaft, the rotating shaft of the third motor will drive the first direction-adjusting gear to rotate in the same direction through the second transmission belt, so that the first driven gear will rotate counterclockwise under the meshing action, and then the corresponding pressure roller will rotate counterclockwise, thereby assisting in pushing the meadow grass felt layer on the first transmission belt, and at the same time squeezing the meadow grass felt layer to compact the meadow grass felt layer to prevent it from falling off during transportation. At the same time, the compacted meadow grass felt layer is not easy to spread out during transportation or laying, thereby reducing the loss of the meadow grass felt layer during transportation.

[0017] 3. In the present invention, when cutting, the driving body drives the whole body to move forward. First, the predetermined area is pre-cut and a groove with a depth of 10-15 cm is dug to guide the cutting knife to accurately cut the turf along the predetermined depth. The roller blade is driven by the driving motor to perform longitudinal cutting first, and then the meadow grass felt layer is cut horizontally by the set cutting knife. The cutting knife pulls or damages the turf on both sides during the horizontal cutting to ensure the neatness of the cutting edge and the integrity of the turf. As it continues to move forward, the lifting part lifts the cut meadow grass felt layer. At this time, the meadow grass felt layer contacts the upper surface of the first transmission belt, and the cut meadow grass felt layer is transported to the first turf conveyor belt under the action of the first transmission belt. During the cutting process, the meadow grass felt layer will be cut off by the set cutting machine every time a distance is cut, thereby dividing the meadow grass felt layer into multiple sections to facilitate the staff to stack the meadow grass felt layer.

[0018] Fourth, in the present invention, the first hydraulic device is provided to change the distance between the docking arm and the driven arm, thereby preventing the first turf supporting plate from interfering with the first turf conveyor belt during rotation adjustment.

[0019] 5. In the present invention, the transmission chain provided can not only provide greater traction to the toothed disc, ensuring the smooth operation and synchronous movement of the pressure roller, but also multiple toothed discs can be arranged between the chains according to usage. These toothed discs can rotate stably, so that multiple pressure rollers can operate synchronously and stably, ensuring that the meadow grass felt layer can be evenly compacted and flattened when passing through the pressure roller.

[0020] 6. In the present invention, the inclined shape of the top portion can reduce the contact area between the top portion and the ground, thereby reducing friction.

[0021] 7. In the present invention, the lower end of the leveling part is in contact with the ground. When the driving vehicle body moves forward, the leveling part will squeeze and level the land that needs to be returned, thereby improving the fit between the meadow grass felt layer and the land. At the same time, the inclined shape of the leveling part can reduce the contact area between the leveling part and the ground, thereby reducing friction.

[0022] 8. In the present invention, since the magnetic poles of the magnetic pin and the magnetic head are opposite, the multi-pressure rod turf fixing nail is prevented from falling off from the extrusion port. The outer wall of the nail body is fixed with turf pressure rods in a circular manner. After the nail body is inserted into the meadow grass felt layer, the provided turf pressure rods can increase the contact area between the multi-pressure rod turf fixing nail and the meadow grass felt layer, thereby improving the fixing effect of the meadow grass felt layer.

The rotating shaft of the second motor 9 is fixedly connected to the docking arm 10, and one side of the docking arm 10 is slidably connected to a slave power arm 11, and a docking support seat 59 is slidably connected to the slave power arm 11, and a docking support seat 59 is rotatably connected to the docking rod 12. Specifically: Figure 4 As shown, a first hydraulic press 19 is fixedly connected to the docking arm 10, and a telescopic end of the first hydraulic press 19 is fixedly connected to the slave arm 11. A second hydraulic press 21 is installed on one side of the slave arm 11, and a telescopic end of the second hydraulic press 21 is fixedly connected to the docking support seat 59. A sixth motor 60 is installed on the docking support seat 59. A third driven gear 61 is fixedly sleeved on the docking rod 12, and an active adjustment gear 20 meshing with the third driven gear 61 is fixedly connected to the rotating shaft of the sixth motor 60. like Figure 1 、 Figure 4 and Figure 5 As shown, the docking rod 12 near the cutting blade 2 is symmetrically provided with a first connecting member 13, and the two first connecting members 13 are fixedly connected to the first turf supporting plate 4, and the cutting blade 2 is fixedly connected to the first connecting member 13; The docking rod 12 near the second turf conveyor belt 5 is symmetrically provided with a second connecting piece 14.

The plurality of toothed discs 17 are engaged with the same transmission chain 18. Compared with the transmission belt, the transmission chain 18 can not only provide a greater traction force to the toothed disc 17, ensuring the smooth operation and synchronous movement of the pressure rollers 16, but also multiple toothed discs 17 can be arranged between the chains according to the usage. These toothed discs 17 can rotate stably, thereby enabling the plurality of pressure rollers 16 to operate synchronously and stably, ensuring that the meadow grass felt layer can be evenly compacted and leveled when passing through the pressure rollers 16; In contrast, the pulleys in the transmission belt can only be set on both sides of the inner wall of the transmission belt.

When the third motor 25 drives the first pulley 23 to rotate clockwise through the rotating shaft, the rotating shaft of the third motor 25 will drive the first direction adjustment gear 33 to rotate in the same direction through the second transmission belt 34, so that the first driven gear 31 will rotate counterclockwise under the meshing action, and then the corresponding pressure roller 16 will rotate counterclockwise, thereby assisting in pushing the meadow grass felt layer on the first transmission belt 24, and at the same time squeezing the meadow grass felt layer to compact the meadow grass felt layer to prevent it from falling off during transportation. At the same time, the compacted meadow grass felt layer is not easy to disperse during transportation or laying, thereby reducing the loss of the meadow grass felt layer during transportation.

The high end of the first turf supporting plate 4 is located above the first turf conveyor belt 3, and the low end of the jacking portion 22 is flush with the bottom of the cutting knife 2, thereby reducing the contact area between the jacking portion 22 and the ground and reducing friction. A cutter 29 is mounted on the blade fixing plate 28 and is located between the cutting blade 2 and the first turf supporting plate 4; The two sides of the blade fixing plate 28 are rotatably connected with support rollers 30. When cutting, the support rollers 30 can support the two sides of the blade fixing plate 28 to ensure stability during cutting; A gap is left between the pressure roller 16 located above the first turf supporting plate 4 and the upper belt body of the first transmission belt 24 for the meadow turf layer to pass through.

[0030] The grass felt layer is then cut off from the grass conveyor belt 3 and the grass is then moved to the grass conveyor belt 3. The grass felt layer is cut off from the grass conveyor belt 3 and the grass is then moved to the grass conveyor belt 3. The grass felt layer is then cut off from the grass conveyor belt 3 and the grass is then moved to the grass conveyor belt 3. A gap is left between the pressure roller 16 located above the first turf conveyor belt 3 and the upper belt body of the first turf conveyor belt 3 for the meadow turf layer to pass through. The pressure roller 16 arranged above the first turf conveyor belt 3 can further level the meadow turf layer.

[0031] When adjusting, the power arm 11, the docking arm 10, the first turf support plate 4 and the cutting knife 2 are quickly moved to the slope through the adjustment structure, and then the first turf support plate 4 and the cutting knife 2 are fine-tuned to improve the accuracy of fitting with the slope surface; Specifically, when it is necessary to cut the meadow on the ramp, the second motor 9 is used to drive the docking arm 10 to rotate, thereby changing the angle of the slave arm 11, the docking arm 10, the first turf support plate 4 and the cutting knife 2. The distance between the docking arm 10 and the slave arm 11 is changed by the first hydraulic valve 19 to prevent the first turf support plate 4 from interfering with the first turf conveyor belt 3 during rotation adjustment. The first motor 7 drives the screw 6 to rotate through the rotating shaft, and the motor base 8 slides on the driving body 1 under the meshing action, thereby changing the distance between the slave arm 11, the docking arm 10, the first turf support plate 4 and the cutting knife 2 and the ramp. Under the action of the first motor 7 and the second motor 9, the slave arm 11, the docking arm 10, the first turf support plate 4 and the cutting knife 2 are quickly moved to the ramp. When fine-tuning, the second hydraulic valve 21 drives the docking support seat 59 to move slightly through its telescopic end, and the sixth motor 60 drives the active adjustment gear 20 to rotate through the rotating shaft. , under the action of meshing, the third driven gear 61 is driven to rotate, the third driven gear 61 drives the docking rod 12 to rotate, the docking rod 12 drives the two first connecting members 13 to rotate, and the two first connecting members 13 drive the first turf supporting plate 4 to rotate. At the same time, the two first connecting members 13 drive the cutting knife 2 to rotate through the blade fixing plate 28, so that the first turf supporting plate 4 and the cutting knife 2 rotate, thereby improving the fit of the first turf supporting plate 4 and the cutting knife 2 to the ramp. In the process of cutting the meadow on the ramp, after each cutting distance, the meadow turf layer is cut off by the cutting machine 29, and then, with the cooperation of the first motor 7, the second motor 9, the first hydraulic press 19, the second hydraulic press 21 and the sixth motor 60, the first turf supporting plate 4 and the cutting knife 2 are reset, thereby transporting the cut meadow turf layer back to the first turf conveyor belt 3 for further transmission and leveling. Without resetting, the staff manually places the cut and compacted meadow turf layer on the first turf conveyor belt 3 for transmission and leveling.

[0032] When the meadow grass layer needs to be restored, such as Figures 9-11 As shown, a flat portion 35 is provided on the side of the second turf supporting plate 15 away from the driving vehicle body 1. The second turf supporting plate 15 and the flat portion 35 are inclined, thereby reducing the contact area between the flat portion 35 and the ground and reducing friction. like Figure 11As shown, multiple groups of second pulleys 36 are rotatably connected to the second turf supporting plate 15, and each group of second pulleys 36 is sleeved with a third transmission belt 37. A fourth motor 38 is provided on the side of the second turf supporting plate 15 away from the leveling portion 35. Multiple second pulleys 36 close to the fourth motor 38 are fixedly connected to the rotating shaft of the fourth motor 38. The fourth motor 38 drives the second pulleys 36 to rotate clockwise through the rotating shaft, so that the third transmission belt 37 transports the cut and leveled meadow turf layer in a direction close to the second turf conveyor belt 5. A second baffle 39 is detachably mounted on the top of the second turf support plate 15. The second baffle 39 is provided with a plurality of second through-grooves 40 corresponding one to one with the third transmission belts 37. The upper belt surfaces of the plurality of third transmission belts 37 extend outward through the second through-grooves 40. The second baffle 39 prevents soil from flowing between the second pulley 36 and the third transmission belt 37 during transportation. like Figure 1 As shown, a fifth motor 58 for driving the second turf conveyor belt 5 is provided on the driving vehicle body 1. The output end of the second turf conveyor belt 5 is located above the third transmission belt 37, and the lower end of the leveling portion 35 is in contact with the ground.

[0033] Further, such as Figure 10 As shown, a plurality of pressure rollers 16 located above the second turf support plate 15 are rotatably connected between the two second connecting members 14. One end of the pressure roller 16 close to the driving body 1 is fixedly connected to a second driven gear 41. The outer wall of the second connecting member 14 is rotatably connected to a second steering gear 43 that meshes with the second driven gear 41 via a second shaft 42. The rotating shaft of the fourth motor 38 is rotatably connected to the second shaft 42 via a fifth transmission belt 44. A gap is left between the pressure roller 16 located above the second turf support plate 15 and the upper belt body of the fifth transmission belt 44 for the meadow turf layer to pass through; When the fourth motor 38 drives the second pulley 36 to rotate clockwise through the rotating shaft, the rotating shaft of the fourth motor 38 will drive the second direction adjustment gear 43 to rotate in the same direction through the fifth transmission belt 44, so that the second driven gear 41 will rotate counterclockwise under the meshing action, and then the corresponding pressure roller 16 will rotate counterclockwise, thereby assisting in pushing the meadow grass felt layer on the third transmission belt 37, and at the same time squeezing the meadow grass felt layer to compact the meadow grass felt layer to prevent the meadow grass felt layer from falling off during transportation.

[0034] like Figure 2 and Figure 3As shown, the bottom of the driving vehicle body 1 is rotatably connected to an auxiliary pressure roller 45, which is located above the second turf conveyor belt 5, and a gap is left between the auxiliary pressure roller 45 and the second turf conveyor belt 5 for the meadow grass felt layer to pass through. The auxiliary pressure roller 45 can limit the meadow grass felt layer on the second turf conveyor belt 5 to prevent the meadow grass felt layer from falling off during transportation.

[0035] When laying the meadow grass felt layer, the first turf supporting plate 4 and the cutting knife 2 are reset, the docking support seat 59 is lifted by the second hydraulic press 21, and the cutting knife 2 is separated from the ground, and the driving vehicle body 1 is moved to the ground that needs to be returned. Then the staff places the leveled meadow grass felt layer on the second turf conveyor belt 5, and the fifth motor 58 drives the second turf conveyor belt 5 to transport the meadow grass felt layer to the third transmission belt 37. The lower end of the leveling part 35 contacts the ground. When the driving vehicle body 1 moves forward, the leveling part 35 will squeeze and level the land that needs to be returned, thereby improving the fit between the meadow grass felt layer and the land; When laying meadow grass on the ramp, after the second turf conveyor belt 5 transports the meadow grass felt layer to the third transmission belt 37, the position of the second turf support plate 15 and the leveling part 35 can be adjusted with the cooperation of the direction adjustment structure to carry out laying. During the adjustment process, the fourth motor 38 stops working. After the adjustment of the direction adjustment structure is completed, the fourth motor 38 starts working, thereby driving the third transmission belt 37 to deliver the meadow grass felt layer, so that the meadow grass felt layer is laid on the ramp; After laying is completed, the second turf pallet 15 is reset through the adjustment structure, and the meadow turf felt layer is transported to the third transmission belt 37 through the second turf conveyor belt 5 again for the next laying. Without resetting, the staff can manually place the cut and compacted meadow turf felt layer on the third transmission belt 37 for the next laying.

[0036] Further, such as Figure 9 、 Figure 12-15 As shown, one side of the two second connecting members 14 is fixedly connected to the fixing assembly for fixing the turf through the support member 46; The fixing assembly includes a docking outer frame 47 fixedly connected to the two support members 46. The docking outer frame 47 is U-shaped and has a plurality of slots 48 at the bottom. The bottom of the inner wall of the docking outer frame 47 is provided with a plurality of extrusion openings 49 corresponding one-to-one to the slots 48. The extrusion openings 49 are adapted to the corresponding slots 48. An ejector plate 50 is slidably connected to the inner wall of the docking outer frame 47. A plurality of magnetic ejector pins 51 corresponding one-to-one to the extrusion openings 49 are fixed to the lower portion of the ejector plate 50. The magnetic ejector pins 51 are slidably connected to the corresponding extrusion openings 49. A telescopic gas rod 52 is installed on the top of the docking outer frame 47 , and the telescopic end of the telescopic gas rod 52 is fixedly connected to the top of the ejector plate 50 .

[0037] Further, such as Figure 2 and Figure 3 As shown, a storage box 53 is installed at the bottom of the driving vehicle body 1, and multiple pressure rod turf fixing nails 54 are provided in the plurality of slots 48. Figure 13 As shown, the multi-pressure rod turf fixing nail 54 is composed of a nail body 55 and a magnetic head 56. The magnetic pole of the magnetic head 56 is opposite to that of the magnetic thimble 51. Figure 15 As shown, the magnetic head 56 slides through the slot 48 and extends into the extrusion port 49, and the top is magnetically attracted to the bottom of the magnetic ejector pin 51. During the laying process, the installation staff inserts the magnetic head 56 of the multi-pressure rod turf fixing nail 54 into the extrusion port 49 along the slot 48. Since the magnetic poles of the magnetic ejector pin 51 and the magnetic head 56 are opposite, the multi-pressure rod turf fixing nail 54 is prevented from falling off from the extrusion port 49. When fixing the meadow grass felt layer, the telescopic end of the telescopic gas rod 52 presses the ejector plate 50 downward, and the ejector plate 50 The magnetic head 56 is squeezed downward by the magnetic thimble 51, so that the nail body 55 at the bottom of the magnetic head 56 is inserted into the meadow grass felt layer. The outer wall of the nail body 55 is fixed with a turf pressure rod 57 in a circular manner. After the nail body 55 is inserted into the meadow grass felt layer, the turf pressure rod 57 can increase the contact area between the multi-pressure rod turf fixing nail 54 and the meadow grass felt layer, thereby improving the fixing effect of the meadow grass felt layer. The storage box 53 can be used to store the multi-pressure rod turf fixing nail 54 for easy access by staff.

[0038] In summary, the workflow of the present invention is as follows: S1: When cutting the meadow grass felt layer in a flat area, the vehicle body 1 is driven to move forward as a whole. First, a pre-cutting process is performed on the predetermined area, and a groove with a depth of 10-15 cm is dug to guide the cutting knife 2 to accurately cut the grass along the predetermined depth. The roller blade 62 is driven by the driving motor 63 to perform longitudinal cutting first, and then the set cutting knife 2 is used to cut the meadow grass felt layer horizontally. As the vehicle body continues to move forward, the lifting part 22 will lift the cut meadow grass felt layer. At this time, the meadow grass felt layer contacts the upper surface of the first transmission belt 24. The cut meadow grass felt layer is transported to the first turf conveyor belt 3 under the action of the first transmission belt 24. During the cutting process, the meadow grass felt layer is cut by the provided cutting machine 29 every time after cutting a certain distance, thereby dividing the meadow grass felt layer into multiple sections, so that the staff can stack the meadow grass felt layer. The first transmission belt 24 transports the meadow grass felt layer to the first turf conveyor belt 3. As the first turf conveyor belt 3 transports the meadow grass felt layer to the driving vehicle body 1, the staff takes the cut meadow grass felt layer from the first turf conveyor belt 3 and sorts and stacks it. S2: When the third motor 25 drives the first pulley 23 to rotate clockwise through the rotating shaft, the rotating shaft of the third motor 25 will drive the first direction adjustment gear 33 to rotate in the same direction through the second transmission belt 34, so that the first driven gear 31 will rotate counterclockwise under the meshing action, and then the corresponding pressure roller 16 will rotate counterclockwise, thereby assisting in pushing the meadow grass felt layer on the first transmission belt 24, and at the same time squeezing the meadow grass felt layer to compact the meadow grass felt layer.

[0039] S3: When cutting the meadow on the ramp, the second motor 9 is used to drive the docking arm 10 to rotate, thereby changing the angles of the slave arm 11, the docking arm 10, the first turf support plate 4 and the cutting knife 2. The first hydraulic valve 19 is used to change the distance between the docking arm 10 and the slave arm 11 to prevent the first turf support plate 4 from interfering with the first turf conveyor belt 3 during rotation adjustment. The first motor 7 drives the screw 6 to rotate through the rotating shaft, and the motor base 8 slides on the driving vehicle body 1 under the meshing action, thereby changing the distance between the slave arm 11, the docking arm 10, the first turf support plate 4 and the cutting knife 2 and the ramp. Under the action of the first motor 7 and the second motor 9, the slave arm 11, the docking arm 10, the first turf support plate 4 and the cutting knife 2 are quickly moved to the ramp. When fine-tuning, the second hydraulic valve 21 drives the docking support seat 59 to move slightly through its telescopic end, and the sixth motor 60 drives the active adjustment gear 20 to rotate through the rotating shaft. Under the meshing action, the third driven gear 61 is driven to rotate, and the third driven gear 61 drives the docking rod 12 to rotate, and the docking rod 12 drives the two first connecting members 13 to rotate, and the two first connecting members 13 drive the first turf supporting plate 4 to rotate. At the same time, the two first connecting members 13 drive the cutting knife 2 to rotate through the blade fixing plate 28, so that the first turf supporting plate 4 and the cutting knife 2 rotate, thereby improving the fit of the first turf supporting plate 4 and the cutting knife 2 to the ramp. In the process of cutting the meadow on the ramp, after each cutting distance, the meadow grass felt layer is cut off by the cutting machine 29, and then, with the cooperation of the first motor 7, the second motor 9, the first hydraulic press 19, the second hydraulic press 21 and the sixth motor 60, the first turf supporting plate 4 and the cutting knife 2 are reset, thereby transporting the cut meadow grass felt layer back to the first turf conveyor belt 3 for further transmission and leveling. Without resetting, the staff manually places the cut and compacted meadow grass felt layer on the first turf conveyor belt 3 for transmission and leveling.

[0040] S4: When laying the meadow grass felt layer, the first turf support plate 4 and the cutting knife 2 are reset, the docking support seat 59 is lifted by the second hydraulic machine 21, and then the cutting knife 2 is separated from the ground, and the driving vehicle body 1 is moved to the ground that needs to be returned. When laying the meadow on the slope, the position of the second turf support plate 15 and the leveling part 35 can be adjusted with the cooperation of the adjustment structure for laying.

[0041] S5: The staff places the leveled meadow grass felt layer on the second turf conveyor belt 5. The fifth motor 58 drives the second turf conveyor belt 5 to transport the meadow grass felt layer to the third transmission belt 37. The lower end of the leveling part 35 contacts the ground. When the driving body 1 moves forward, the leveling part 35 will squeeze and level the land that needs to be returned, thereby improving the fit between the meadow grass felt layer and the land.

[0042] S6: When laying meadow on the ramp, after the second turf conveyor belt 5 transports the meadow grass felt layer to the third transmission belt 37, the position of the second turf support plate 15 and the leveling part 35 can be adjusted with the cooperation of the adjustment structure for laying. During the adjustment process, the fourth motor 38 stops working. After the adjustment of the adjustment structure is completed, the fourth motor 38 starts working, thereby driving the third transmission belt 37 to deliver the meadow grass felt layer, so that the meadow grass felt layer is laid on the ramp.

[0043] S7: During the laying process, the staff inserts the magnetic head 56 of the multi-pressure rod turf fixing nail 54 into the extrusion port 49 along the slot 48. Under the action of the opposite magnetic poles of the magnetic head 56 and the magnetic thimble 51, the top of the magnetic head 56 will be magnetically attracted to the bottom of the magnetic thimble 51. When fixing the meadow grass felt layer, the telescopic end of the telescopic gas rod 52 presses the thimble plate 50 downward, and the thimble plate 50 squeezes the magnetic head 56 downward through the magnetic thimble 51, thereby piercing the nail body 55 at the bottom of the magnetic head 56 into the meadow grass felt layer and the land. As the nail body 55 is inserted, the nail body The friction between 55 and the meadow grass felt layer and the land increases. After being fixed, the telescopic end of the telescopic gas rod 52 pulls the ejector plate 50 upward to reset it. The ejector plate 50 drives the magnetic ejector 51 to move upward and reset. During the resetting process of the magnetic ejector 51, the friction between the nail body 55 and the meadow grass felt layer and the land increases. The meadow grass felt layer and the land will firmly fix the nail body 55, so that the magnetic ejector 51 will separate from the magnetic head 56 when it moves upward and resets, thereby leaving the multi-pressure rod turf fixing nail 54 on the meadow grass felt layer, fixing the meadow grass felt layer to the land.

[0044] S8: After the ramp is laid, the second turf pallet 15 is reset through the adjustment structure, and the meadow turf felt layer is transported to the third transmission belt 37 through the second turf conveyor belt 5 again for the next laying. Without resetting, the staff can manually place the cut and compacted meadow turf felt layer on the third transmission belt 37 for the next laying.

10. The method for using the alpine meadow grass carpet layer effective stripping and restoration ecological restoration device according to any one of claims 1 to 9, characterized in that: The steps include: S1: When cutting a meadow grass felt layer in a flat area, the vehicle body (1) is driven to move the vehicle body forward as a whole. First, a pre-cutting process is performed on a predetermined area, and a groove pit with a depth of 10-15 cm is dug to guide the cutting knife (2) to accurately cut the grass along the predetermined depth. The rolling blade (62) is driven by the driving motor (63) to first perform longitudinal cutting, and then the meadow grass felt layer is transversely cut by the set cutting knife (2). As the vehicle body continues to move forward, the lifting part (22) lifts up the cut meadow grass felt layer. At this time, the meadow grass felt layer contacts the upper surface of the first transmission belt (24). The first transmission belt (24) transports the cut meadow grass felt layer to the first turf conveyor belt (3). During the cutting process, the meadow grass felt layer is cut by a provided cutting machine (29) after each cutting of a certain distance, thereby dividing the meadow grass felt layer into a plurality of sections, so that the staff can stack the meadow grass felt layer. The first transmission belt (24) transports the meadow grass felt layer to the first turf conveyor belt (3). As the first turf conveyor belt (3) transports the meadow grass felt layer to the driving vehicle body (1), the staff takes the cut meadow grass felt layer from the first turf conveyor belt (3) and sorts and stacks it. S2: When the third motor (25) drives the first pulley (23) to rotate clockwise via the rotating shaft, the rotating shaft of the third motor (25) drives the first steering gear (33) to rotate in the same direction via the second transmission belt (34), so that the first driven gear (31) rotates counterclockwise under the meshing action, thereby causing the corresponding pressure roller (16) to rotate counterclockwise, thereby assisting in pushing the meadow grass felt layer on the first transmission belt (24), and at the same time squeezing the meadow grass felt layer to compact the meadow grass felt layer; S3: When cutting the meadow on the ramp, the second motor (9) is used to drive the docking arm (10) to rotate, thereby changing the angles of the slave arm (11), the docking arm (10), the first turf support plate (4) and the cutting knife (2). The first hydraulic valve (19) is used to change the distance between the docking arm (10) and the slave arm (11) to prevent the first turf support plate (4) from interfering with the first turf conveyor belt (3) during rotation adjustment. The first motor (7) drives the screw (6) to rotate through the rotating shaft, and the motor base (8) is meshed to rotate. The driving vehicle body (1) slides on the ramp, thereby changing the distance between the slave power arm (11), the docking force arm (10), the first turf support plate (4) and the cutting knife (2) and the ramp. Under the action of the first motor (7) and the second motor (9), the slave power arm (11), the docking force arm (10), the first turf support plate (4) and the cutting knife (2) are quickly moved onto the ramp. When fine-tuning is performed, the second hydraulic device (21) drives the docking support seat (59) to move slightly through its telescopic end, and the sixth motor (60) drives the active adjustment gear (20) to move through the rotating shaft. The first turf support plate (4) is rotated, and the third driven gear (61) is driven to rotate under meshing action. The third driven gear (61) drives the docking rod (12) to rotate. The docking rod (12) drives the two first connecting members (13) to rotate. The two first connecting members (13) drive the first turf support plate (4) to rotate. At the same time, the two first connecting members (13) drive the cutting knife (2) to rotate through the blade fixing plate (28), thereby rotating the first turf support plate (4) and the cutting knife (2), thereby improving the fit between the first turf support plate (4) and the cutting knife (2) and the ramp, and cutting the meadow on the ramp. During the process, after each cutting of a certain distance, the meadow grass felt layer is cut off by the cutting machine (29), and then the first turf support plate (4) and the cutting knife (2) are reset with the cooperation of the first motor (7), the second motor (9), the first hydraulic press (19), the second hydraulic press (21) and the sixth motor (60), so that the cut meadow grass felt layer is transported back to the first turf conveyor belt (3) for further conveying and leveling. Without resetting, the staff manually places the cut and compacted meadow grass felt layer on the first turf conveyor belt (3) for conveying and leveling. S4: When laying a meadow grass felt layer in a flat area, the first grass support plate (4) and the cutting knife (2) are reset, the docking support seat (59) is lifted by the second hydraulic device (21), and the cutting knife (2) is separated from the ground, and the driving vehicle body (1) is moved to the ground to be returned; S5: The staff places the leveled meadow grass felt layer on the second turf conveyor belt (5), and the fifth motor (58) drives the second turf conveyor belt (5) to transport the meadow grass felt layer to the third transmission belt (37). The lower end of the leveling part (35) contacts the ground, and when the driving vehicle body (1) moves forward, the leveling part (35) squeezes and levels the land to be returned; S6: When laying the meadow grass on the ramp, after the second turf conveyor belt (5) transports the meadow grass felt layer to the third transmission belt (37), the position of the second turf support plate (15) and the leveling part (35) can be adjusted with the cooperation of the direction adjustment structure to carry out laying. During the adjustment process, the fourth motor (38) stops working. After the adjustment of the direction adjustment structure is completed, the fourth motor (38) starts working, thereby driving the third transmission belt (37) to deliver the meadow grass felt layer, so that the meadow grass felt layer is laid on the ramp; S7: During the laying process, the staff inserts the magnetic head (56) of the multi-pressure rod turf fixing nail (54) into the extrusion port (49) along the slot (48). Under the action of the opposite magnetic poles of the magnetic head (56) and the magnetic thimble (51), the top of the magnetic head (56) is magnetically attracted to the bottom of the magnetic thimble (51). When fixing the meadow grass felt layer, the telescopic end of the telescopic gas rod (52) presses the thimble plate (50) downward, and the thimble plate (50) presses the magnetic head (56) downward through the magnetic thimble (51), thereby piercing the nail body (55) at the bottom of the magnetic head (56) into the meadow grass felt layer and the ground. As the nail body (55) moves After the nail body (55) is inserted into the grass, the friction between the nail body (55) and the meadow grass felt layer and the ground increases. After the nail body (55) is fixed, the telescopic end of the telescopic gas rod (52) pulls the ejector plate (50) upward to reset the nail body, and the ejector plate (50) drives the magnetic ejector pin (51) to move upward to reset the nail body. During the reset process, the friction between the nail body (55) and the meadow grass felt layer and the ground increases. The meadow grass felt layer and the ground will firmly fix the nail body (55). When the magnetic ejector pin (51) moves upward to reset the nail body, the magnetic ejector pin (51) will separate from the magnetic head (56). The multi-pressure rod grass fixing nail (54) is left on the meadow grass felt layer, so that the meadow grass felt layer and the ground are fixed. S8: After the ramp is laid, the second turf support plate (15) is reset by the adjustment structure, and the meadow turf felt layer is transported to the third transmission belt (37) by the second turf conveyor belt (5) again for the next laying. Without resetting, the staff can manually place the cut and compacted meadow turf felt layer on the third transmission belt (37) for the next laying.
