Description

Technical Field

[0001] This invention relates to the field of turf planting technology, and in particular to a device for turf planting and repair of wounds on high-altitude and cold slopes. Background Technology

[0002] In slope restoration in high-altitude and cold regions, turf planting is a common method. Current procedures require manual mowing of the lawn, followed by fertilization of the soil, and finally covering with turf. This step-by-step process is time-consuming and inefficient. On steep slopes, the turf is prone to slipping, failing to effectively cover the soil. Furthermore, soil remediation and turf restoration cannot be carried out simultaneously, prolonging the overall project duration. These problems are more pronounced in high-altitude and cold environments, impacting the progress of ecological restoration. High-altitude meadow soils have a thick humus layer and high organic matter content, but their loose structure results in insufficient adhesion of the turf after restoration, making it susceptible to displacement under gravity. Existing equipment struggles to address these cumbersome procedures and stability issues, leading to unsatisfactory restoration results.

[0003] To address the above problems, this invention proposes a device for planting and repairing turf on damaged slopes in high-altitude and cold regions. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing methods, such as cumbersome operation leading to extremely low soil remediation efficiency, easy turf slippage from slopes, and the inability to synchronize soil remediation with turf restoration. Therefore, this invention proposes a turf planting and restoration device for damaged slopes in high-altitude and cold regions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for planting and repairing turf on high-altitude and cold slopes includes a main frame, a cover plate on top of the main frame, a linkage arm on top of the cover plate, and the linkage arm is used to connect with a traction machine. It also includes: Two connecting frames are fixed to the bottom of the main frame. Each of the two connecting frames is equipped with a cutting blade on one side. The same V-shaped grass-lifting plate is fixed between the two connecting frames for lifting the cut lawn and re-covering it. Multiple steel nails are provided between the two cutting blades for piercing the lawn before lifting it to reduce the connection between the lawn and the soil. The reciprocating assembly, located between the main frame and two cutting blades, drives multiple steel nails to reciprocate and pierce the lawn, leaving multiple penetration holes in the pierced lawn to enhance the adhesion between the lawn and the soil after backfilling. The material storage box and the drainage pipe are provided. The material storage box is fixed to the top of the main frame, and the drainage pipe is located at the bottom of the V-shaped drafting board and is in fluid communication with the material storage box through a connecting pipe. It is used to spray organic fertilizer onto the soil. The water tank and the sprinkler heads are provided. The water tank is fixed to the bottom of the main frame, and the multiple sprinkler heads are set at the bottom of the water tank for watering the lawn before replanting, so that the water flows through the infiltration holes to enhance the adhesion of the grass and soil. The compaction assembly, located at the bottom of the main frame on the side away from the rotating roller, is used to compact the lawn that has been re-covered on the soil from the V-shaped turfboard, allowing the lawn to adhere to the soil under the influence of moisture.

[0006] Furthermore, it also includes an adjustment component, the adjustment component comprising: A guide rod slides through the main frame, its top end fixed to the bottom of the cover plate; multiple electric push rods I are fixed to the bottom of the cover plate and their output shafts are connected to the top of the main frame for adjusting the height of the main frame; a column is fixed to the top of the cover plate, and a rotating guide groove is provided inside the linkage arm, with a rotating shaft I rotatably connected to the rotating guide groove and fixed to the top of the column; a worm gear is fixedly sleeved on the outer wall of the rotating shaft I; a worm is rotatably connected to the top of the linkage arm through a base and meshes with the worm gear for driving the column to rotate to adjust the angle of the main frame.

[0007] Furthermore, the reciprocating assembly includes multiple upright plates fixed to one side of the bottom of the main frame, a common lifting plate sliding on one side of the multiple upright plates, multiple steel nails fixed to the bottom of the lifting plate, a support arm I fixed to one side of each of the two connecting frames, a rotating shaft II rotatably passing through each of the two support arms I, and a cutting blade fixedly sleeved on the outer wall of the rotating shaft II, a U-shaped shaft fixed between the two rotating shafts II, a fixed shaft fixed to the side of the lifting plate near the U-shaped shaft via a base, multiple connecting rods rotatably connecting the fixed shaft and the U-shaped shaft, and the U-shaped shaft drives the lifting plate to reciprocate up and down via the connecting rods.

[0008] Furthermore, it also includes a rotary tillage assembly, located below the main frame, for rotary tilling the soil after the lawn is lifted to improve soil quality. The rotary tillage assembly includes a U-shaped support frame that slides through the main frame. An electric push rod II is fixed to the top of the main frame. The output shaft of the electric push rod II is fixedly connected to the inner wall of the top of the U-shaped support frame. A rotating shaft IV located below the V-shaped lawn-lifting plate is rotatably mounted inside the U-shaped support frame. A rotary tillage roller is fixedly fitted onto the outer wall of the rotating shaft IV for rotary tilling the soil after the lawn is lifted. One end of the rotating shaft IV rotatably passes through one of the connecting frames and is fixed... A synchronous pulley II is fixedly provided. A rotating shaft III is rotatably connected between the two connecting frames. A rotating roller located above one side of the V-shaped turfboard is fixedly sleeved on the outer wall of the rotating shaft III. Multiple elastic tabs are fixed on the outer wall of the rotating roller. The cooperation between the rotating roller and the elastic tabs is used to transport the lawn on the V-shaped turfboard to one side. One end of the rotating shaft III rotatably passes through one of the connecting frames and is fixed with a synchronous pulley I. A synchronous pulley III and a synchronous pulley IV are rotatably connected to one side of the connecting frame adjacent to the synchronous pulley II. The synchronous pulleys III, II, IV and I are connected by a synchronous belt drive.

[0009] Furthermore, a lifting guide groove is provided on one side of the connecting frame adjacent to the synchronous wheel II. A fixed rod is fixed in the lifting guide groove. A lifting slider is slidably connected to the outer wall of the fixed rod. The lifting slider is rotatably connected to the synchronous wheel IV. A spring is fixed between the bottom of the lifting slider and the bottom inner wall of the lifting guide groove. The spring is sleeved on the outer wall of the fixed rod.

[0010] Furthermore, the drainage pipe is located between the rotating shaft IV and the rotating roller, and is used to spray organic fertilizer onto the soil to be rotary tilled.

[0011] Furthermore, the water tank is fixed to the bottom of the main frame on the side away from the rotating roller.

[0012] Furthermore, a position sensor is fixed at the bottom of the main frame, and the position sensor is located above the highest point of the V-shaped drafting board, while the rotating shaft IV is located below the highest point of the V-shaped drafting board.

[0013] Furthermore, the V-shaped turf-lifting board has a lower height at one end near the cutting blade than at the other end, with the lower end used to lift the lawn and the higher end used to cover the lawn.

[0014] Furthermore, the compaction assembly includes a rotating shaft rotatably connected to the two connecting frames on their adjacent sides. Two support arms II are fixedly sleeved on the outer wall of the rotating shaft. A torsion spring is fixed to the opposite side of each of the two support arms II, and the torsion spring is fixedly connected to the corresponding connecting frame. Both torsion springs are sleeved on the outer wall of the rotating shaft. The same compaction roller is rotatably connected to the opposite side of the two support arms II, and the compaction roller is located on the side of the nozzle away from the rotating shaft IV. This assembly is used to compact the lawn that has been re-covered on the soil from the V-shaped turfboard.

[0015] Beneficial effects: In this invention, each of the two connecting frames has a cutting blade rotatably mounted on one side via a support arm I, and the same V-shaped grass-raising plate is fixed between the two connecting frames; the motor drives the cutting blade to cut both sides of the lawn, and when moving, the bottom of one side of the V-shaped grass-raising plate is flush with the bottom of the cutting blade, so one side of the V-shaped grass-raising plate inserts into the soil to lift the cut lawn. As the main frame moves, the lawn can move on the V-shaped grass-raising plate. In addition, as the lawn moves on the V-shaped grass-raising plate, it can be re-covered on the soil. The peeling and re-covering of the lawn are completed simultaneously, making the operation simple and improving efficiency. In this invention, a rotating shaft IV located below the V-shaped turf-raising board is rotatably mounted inside the U-shaped load-bearing frame, and a rotating shaft III is rotatably connected between the two connecting frames. The synchronous pulleys III, II, IV, and I are connected by a synchronous belt drive. The cooperation between the rotating roller and the elastic paddle can transport the lawn to one side on the V-shaped turf-raising board. During the transport process, the soil of the lawn can be rotary tilled, and the lawn stripping, rotary tilling, organic fertilizer spraying, and replanting can be carried out simultaneously, improving the efficiency of ecological restoration. In this invention, a single lifting plate slides on one side of multiple upright plates, and multiple steel nails are fixed to the bottom of the lifting plate. A U-shaped shaft is fixed between the two rotating shafts II, and multiple connecting rods are rotatably connected between the fixed shaft and the U-shaped shaft. Multiple nozzles are fixed to the bottom of the water tank. When the cutting blade cuts the lawn, the steel nails move up and down repeatedly, continuously piercing the lawn to be lifted, reducing the connection between the lawn and the soil, and facilitating the lifting of the lawn by the V-shaped grass-lifting board. In addition, when the lawn is later re-covered on the soil, the water sprayed by the nozzles can quickly penetrate into the soil through the holes pierced by the steel nails, irrigating the lawn and soil, increasing the adhesion between the lawn and the soil, and preventing the lawn from slipping off the soil.

[0016] In this invention, the stripping, rotary tillage, spraying of organic fertilizer and replanting of lawn can be carried out simultaneously, improving the efficiency of ecological restoration. The insertion of steel nails into the lawn helps with the stripping and replanting of lawn, allowing the lawn to be stably covered on the soil and preventing the lawn from slipping off.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1 Reference Figures 1-3 This ecological restoration equipment relates to the field of turf stripping and replanting technology. The equipment mainly includes a main frame 1, with a cover plate 2 fixed above it. A linkage arm 6 is located above the cover plate 2, connecting to traction machinery (such as a tractor) to enable equipment movement. At the bottom of the main frame 1, two connecting frames 11 are fixed. Each connecting frame 11 has a cutting blade 15 mounted on one side. The cutting blade 15 can be made of wear-resistant high-carbon tool steel (such as SK5, hardness HRC 58-62), with a surface treated by low-temperature nitriding (0.1-0.3mm depth). Its sharpness is maintained for ≥200 hours, adaptable to various geological conditions such as sandy soil and clay, and used for cutting the two sides of the lawn. Between the two connecting frames 11, a V-shaped turf-lifting board 12 is fixed. The function of this board is to lift the cut turf after the cutting blade 15 completes the cut and to subsequently replant the turf in its original position. Between the two cutting blades 15, there are also a number of steel nails 18. These steel nails 18 are used to puncture the lawn before it is lifted, so as to reduce the connection between the lawn and the soil and make it easier to lift. The steel nails 18 can be made of tungsten cobalt hard alloy (such as YG8), with a bending strength ≥1800MPa and a tip designed as a triangular pyramid (with an included angle of 60°).

[0021] Reference Figure 1 and Figure 4To achieve angle and height adjustment of the main frame 1, the equipment is equipped with an adjustment component. Specifically, the adjustment component includes a guide rod 3 that slides through the main frame 1, with its top end fixedly connected to the bottom of the cover plate 2. At the bottom of the cover plate 2, multiple electric push rods I4 are fixedly mounted, and the output shafts of these electric push rods I4 are all fixedly connected to the top of the main frame 1. By controlling the extension and retraction of the electric push rods I4, the lifting and lowering of the main frame 1 can be controlled, thereby adjusting the working height of the cutting blade 15 and the V-shaped drafting board 12. Furthermore, a column 5 is fixedly mounted on the top of the cover plate 2, and a rotating guide groove 7 is provided within the linkage arm 6. A rotating shaft I8 is rotatably connected within the rotating guide groove 7. The top end of the column 5 extends into the rotating guide groove 7 and is fixedly connected to the rotating shaft I8. A worm gear 9 located within the column 5 is fixedly sleeved on the outer wall of the rotating shaft I8. At the top of the linkage arm 6, a worm 10 is rotatably connected via a base, and this worm 10 meshes with the worm gear 9.

[0022] Specifically, the worm gear 10 is driven to rotate by the motor. The cooperation between the worm gear 10 and the worm wheel 9 can drive the column 5, the cover plate 2 and the main frame 1 to rotate as a whole, thereby adjusting the relative angle between the main frame 1 and the slope, ensuring that the main frame 1 and the connecting frame 11 are perpendicular to the slope when working.

[0023] Reference Figure 3 , Figure 6 and Figure 7 To drive multiple steel nails 18 to reciprocate and pierce the lawn, the equipment also includes a reciprocating assembly. Specifically, the reciprocating assembly includes multiple upright plates 16 fixed to one side of the bottom of the main frame 1, and a lifting plate 17 slidably connected to one side of each upright plate 16. Multiple steel nails 18 are fixed to the bottom of the lifting plate 17. On one side of each of the two connecting frames 11, a support arm I 13 is fixed, and a rotating shaft II 14 rotatably passes through each of the two support arms I 13. The cutting blade 15 is fixedly sleeved on the outer wall of these rotating shafts II 14. A U-shaped shaft 19 is also fixed between the two rotating shafts II 14. A fixed shaft 21 is fixed to the side of the lifting plate 17 near the U-shaped shaft 19 via a base, and multiple connecting rods 20 are rotatably connected between the fixed shaft 21 and the U-shaped shaft 19. When the cutting blade 15 rotates, it will drive the U-shaped shaft 19 to rotate synchronously. The U-shaped shaft 19 then drives the lifting plate 17 and the steel nail 18 to move up and down repeatedly through the connecting rod 20, thereby piercing the lawn.

[0024] Reference Figure 2 , Figure 3 , Figure 5 and Figure 8In addition, to rotary tillage the soil after the lawn is lifted, the equipment is equipped with a rotary tillage assembly. This assembly is located below the main frame 1 and is driven by a motor to rotate the rotary tillage blades, breaking up and loosening the soil, and thoroughly mixing the organic fertilizer with the soil. The rotary tillage assembly mainly includes a U-shaped support frame 36 that slides through the main frame 1, and an electric push rod II 37 is firmly installed on the top of the main frame 1. The output shaft of the electric push rod II 37 is fixedly connected to the inner wall of the top of the U-shaped support frame 36, so that the U-shaped support frame 36 can be moved up and down by extending and retracting the electric push rod II 37. Inside the U-shaped support frame 36, a rotating shaft IV 25 is located below the V-shaped lawn-lifting plate 12. A rotary tillage roller 26 is fixedly fitted on the outer wall of this rotating shaft IV 25, and its main function is to rotary tillage the soil under the lawn lifted by the V-shaped lawn-lifting plate 12, breaking up and loosening the soil, and thoroughly mixing the organic fertilizer with the soil. One end of the rotating shaft IV 25 passes through one of the connecting frames 11, and a synchronous pulley II 28 is fixed at this end. A rotating shaft III 22 is also rotatably connected between the two connecting frames 11. A rotating roller 23, located above one side of the V-shaped turfboard 12, is fixedly fitted onto the outer wall of this rotating shaft. Multiple elastic tabs 24 are fixed to the outer wall of the rotating roller 23. The cooperation of these elastic tabs 24 with the rotating roller 23 smoothly transports the turf on the V-shaped turfboard 12 to one side. One end of the rotating shaft III 22 also passes through one of the connecting frames 11, and a synchronous pulley I 27 is fixed at this end. Synchronous pulleys III 29 and IV 30 are also rotatably connected to one side of the connecting frame 11 adjacent to synchronous pulley II 28. These four synchronous pulleys (synchronous pulley I 27, synchronous pulley II 28, synchronous pulley III 29, and synchronous pulley IV 30) are connected by a synchronous belt 31. When the motor drives the rotating roller 23 to rotate, the synchronous belt 31 drives the other synchronous pulleys and the corresponding rotating shafts to rotate together, thereby achieving the linkage of the entire rotary tillage assembly.

[0025] Reference Figure 9 To ensure stable tension of the synchronous belt 31, a lifting guide groove 32 is provided on one side of the connecting frame 11 adjacent to the synchronous pulley II 28. A fixed rod 34 is fixed inside the lifting guide groove 32, and a lifting slider 33 is slidably connected to the outer wall of the fixed rod 34. The lifting slider 33 is rotatably connected to the synchronous pulley IV 30, and a spring 35 is fixed between the bottom of the lifting slider 33 and the bottom inner wall of the lifting guide groove 32. This spring 35 is sleeved on the outer wall of the fixed rod 34. When the rotating shaft IV 25 moves down, the cooperation of the spring 35 and the lifting slider 33 can automatically adjust the tension of the synchronous belt 31, ensuring that the synchronous belt 31 can smoothly drive the rotating shaft IV 25 and the rotating shaft III 22 to rotate.

[0026] Reference Figure 2 , Figure 3 and Figure 10In addition, a storage box 40 is fixed to the top of the main frame 1 to spray organic fertilizer before rotary tillage of the soil. A diversion pipe 39 is fixed to the bottom of the V-shaped tillage plate 12 via a base, and this diversion pipe 39 is located between the rotating shaft IV 25 and the rotating roller 23. The diversion pipe 39 is connected to the storage box 40 via a connecting pipe 41, so that the organic fertilizer in the storage box 40 can be transported to the diversion pipe 39 for spraying.

[0027] Reference Figure 3 A water tank 42 is fixedly installed on the bottom of the main frame 1, away from the rotating roller 23. The capacity of the water tank 42 is sufficient to meet the needs of fully watering the lawn that is about to be replanted. At the bottom of the water tank 42, multiple nozzles 43 are fixedly connected. These nozzles 43 are evenly distributed to ensure uniform watering, which can not only irrigate the lawn, but also increase the moisture of the lawn-soil contact surface, so that the lawn can be placed stably on the soil and improve the survival rate of the lawn.

[0028] Reference Figure 3 , Figure 5 and Figure 6 At the bottom of the main frame 1, a position sensor 38 is fixedly installed, positioned above the highest point of the V-shaped turf-raising board 12. Simultaneously, the rotating shaft IV 25 is located below the highest point of the V-shaped turf-raising board 12. When one end of the turf moves to the position of the position sensor 38, the sensor sends a signal, driving the rotating shaft IV 25 downwards to rotary till the soil after the turf has been lifted. This allows for precise rotary tilling of the soil after the turf has been removed, preparing it for subsequent replanting operations.

[0029] Reference Figure 3 The V-shaped turf-lifting plate 12 has a lower height at one end near the cutting blade 15 than at the other end. During operation, the lower end is used to lift the turf, while the higher end is used to re-lift it. This makes the turf removal and re-lifting operations smoother and improves work efficiency.

[0030] In practice, the turf to be stripped is first cut using the cutting blade 15, and then the turf is lifted using the V-shaped turf-lifting plate 12. When one end of the turf moves to the position sensor 38, the position sensor 38 sends a signal, driving the rotating shaft IV 25 to move downwards to till the soil. Next, the turf is returned to the tilled soil using the higher end of the V-shaped turf-lifting plate 12. At this time, the nozzle 43 at the bottom of the water tank 42 sprays water on the turf to increase the moisture content of the turf and soil. Finally, the compaction roller 46, under the action of the support arm II 45 and the torsion spring 47, compacts the turf and soil, completing the entire turf stripping and replanting ecological restoration process.

[0031] Example 2 refer to Figure 11 In addition, a rotating shaft 44 is rotatably connected to the side of the two connecting frames 11 that are close to each other. Two support arms II 45 are fixedly sleeved on the outer wall of the rotating shaft 44. A torsion spring 47 is fixedly connected to the side of the two support arms II 45 that are far from each other, and the torsion spring 47 is fixedly connected to the corresponding connecting frame 11. The two torsion springs 47 are sleeved on the outer wall of the rotating shaft 44, providing a certain degree of elasticity to the support arms II 45. A pressure roller 46 is rotatably connected to the side of the two support arms II 45 that are close to each other, and the pressure roller 46 is located on the side of the nozzle 43 that is far from the rotating shaft IV 25.

[0032] When the lawn is re-covered on the soil from one side of the V-shaped turfboard 12, the pressure roller 46 compacts the lawn against the soil due to the elasticity of the support arm II 45 and the pressure roller 46 under the action of the torsion spring 47. This ensures that the wet parts of the lawn adhere well to the soil, preventing the lawn from slipping and improving its stability.

[0033] A method for using a turf planting and repair device for wounds on high-altitude and cold slopes includes the following steps: S1. The device is installed on the traction machine via the linkage arm 6. When it is necessary to place the device vertically to the slope, the worm gear 10 is driven to rotate by the motor. The cooperation between the worm gear 10 and the worm wheel 9 drives the column 5, the cover plate 2 and the main frame 1 to rotate until the main frame 1 and the connecting frame 11 are perpendicular to the slope. S2. When cutting the lawn and exposing the soil to be repaired for soil restoration, simply drive the main frame 1 to move down as a whole by using the electric push rod I4 until the cutting blade 15 is inserted into the lawn. Then, the motor drives the cutting blade 15 to cut the lawn on both sides. The traction device drives the main frame 1 to move as a whole through the linkage arm 6. When moving, the bottom of one side of the V-shaped grass-raising board 12 is flush with the bottom of the cutting blade 15. Therefore, one side of the V-shaped grass-raising board 12 is inserted into the soil to lift up the cut lawn. As the main frame 1 moves, the lawn can move on the V-shaped grass-raising board 12. S3. When the cutting blade 15 rotates, it drives the U-shaped shaft 19 to rotate. The cooperation between the U-shaped shaft 19 and the connecting rod 20 drives the lifting plate 17 and the steel nail 18 to move up and down repeatedly. This can continuously poke holes in the lawn to be lifted, reducing the connection between the lawn and the soil, making it easier for the V-shaped turf-lifting board 12 to lift the lawn. In addition, when the lawn is re-covered on the soil under the action of the V-shaped turf-lifting board 12, the water sprayed by the nozzle 43 can quickly penetrate into the soil through the holes penetrated by the steel nail 18, which is used to irrigate the lawn and the soil, keeping the contact area between the soil and the lawn moist, increasing the adhesion between the lawn and the soil, and preventing the lawn from slipping off the soil. S4. When the lawn moves on the V-shaped turf cutting board 12, the rotating roller 23 is driven by the motor to rotate. The cooperation between the rotating roller 23 and the elastic lever 24 can smoothly transport the lawn to one side. In addition, when the position sensor 38 detects that the lawn has moved to the highest point of the V-shaped turf cutting board 12, the rotary tillage roller 26 is just above the soil where the lawn is being cut. The electric push rod II 37 drives the U-shaped load-bearing frame 36 and the rotating shaft IV 25 to move down, so that the rotary tillage roller 26 can extend into the soil to till the soil. In addition, the drainage pipe 39 can spray the organic fertilizer stored in the storage box 40 onto the soil. The rotary tillage roller 26 can fully mix the organic fertilizer into the soil to improve the soil quality. In addition, when the rotating shaft IV 25 moves down, the cooperation between the spring 35 and the lifting slider 33 can ensure the tension of the synchronous belt 31, so that the synchronous belt 31 can drive the rotating shaft IV 25 and the rotating shaft III 22 to rotate. S5. When the lawn is re-covered on the soil from one side of the V-shaped turfboard 12, the support arm II 45 and the pressing roller 46, under the action of the torsion spring 47, can compact the lawn and the soil, so that the wet parts of the lawn and the soil are fully bonded and the lawn is prevented from slipping.
