Description

Technical Field

[0001] This invention application relates to the field of environmental ecological restoration technology, and in particular to a reseeding device and method for grassland ecological restoration. Background Technology

[0002] The process and causes of grassland degradation are complex. Changes in grassland ecosystems are always accompanied by various natural factors such as geography, climate, soil, and disasters. Therefore, the restoration of degraded grasslands and reseeding for grassland ecological restoration are imperative.

[0003] In existing technology, firstly, a reseeding area is selected and a trench is dug. A reseeding device for grassland ecological restoration includes a platform. The bottom of the platform is fixedly connected to two vertical plates, and a central shaft is rotatably inserted through the two vertical plates. A roller is installed on the central shaft between the two vertical plates. A grass seed placement box is fixedly connected to the top of the platform. A feeding pipe is interconnected on both sides of the grass seed placement box. A transmission rod is rotatably connected to the inner wall of the feeding pipe, and the transmission rod is connected to the central shaft through a transmission mechanism. Two connecting rods are fixedly connected to the top of the platform, and a handle is fixedly connected to the end of the connecting rod away from the grass seed placement box. By setting components such as the central shaft, the lever plate, the transmission rod, and the pulley assembly, the device can drive the lever plate to rotate synchronously as the roller rolls forward, thereby achieving the effect of automatic quantitative feeding and sowing.

[0004] The aforementioned technologies can achieve automated quantitative feeding and sowing, but different grass species have significantly different requirements for growing space. For example, fibrous rooted herbaceous plants are suitable for denser sowing furrows to quickly form vegetation cover; while rhizomatous herbaceous plants require wider sowing furrows to avoid competition for nutrients and light during growth. Leguminous nitrogen-fixing plants (such as alfalfa) require flexible spacing between 15-25 cm depending on the mixing ratio with gramineous plants to achieve nutrient complementarity. This makes it difficult to meet the sowing needs of different seeds. These problems severely restrict the effectiveness of grassland ecological restoration reseeding, resulting in an inability to adapt to the sowing spacing of different seeds. Summary of the Invention

[0005] To address the problem of being unable to adapt to different seed sowing spacings, this application provides a reseeding device and method for grassland ecological restoration.

[0006] Firstly, this application provides a reseeding device for grassland ecological restoration, which adopts the following technical solution: A reseeding device for grassland ecological restoration includes a trenching component; The trenching assembly includes a lifting component and multiple sets of trenching components. The lifting component includes a lifting plate, and the length direction of the lifting plate is perpendicular to the length direction of the trench. The lifting plate has a sliding groove on one side for sliding multiple sets of trenching components. The sliding groove is opened along the length direction of the lifting plate. Multiple sets of trenching components are spaced apart along the length direction of the sliding groove. Each set of trenching components includes two sliding seats that slide along the sliding groove and two trenching cutters for trench excavation. The trenching cutters are installed on the side of the sliding seats near the ground. The trenching assembly also includes an adjusting component, which is mounted on the lifting plate. The adjusting component includes a first bidirectional screw and a drive motor. The first bidirectional screw is located in the slide groove, and the setting direction of the first bidirectional screw is consistent with the opening direction of the slide groove. Both ends of the first bidirectional screw are rotatably connected to the lifting plate. The drive motor is connected to the lifting plate, and the output shaft of the drive motor is coaxially fixed with one end of the first bidirectional screw. Multiple sets of grooved components are evenly distributed on the first bidirectional screw. In each set of grooved components, one of the sliding seats is slidably connected to the first bidirectional screw, and the other sliding seat is threadedly connected to the first bidirectional screw. The sliding seat slidably connected to the first bidirectional screw is slidably connected to the sliding seat threadedly connected to the first bidirectional screw.

[0007] In one specific implementation, the adjusting component further includes multiple adjusting cylinders, each corresponding to one of the grooved components. The adjusting cylinders are positioned in the same direction as the sliding grooves. The cylinder body of the adjusting cylinder is connected to the sliding seat that is threadedly connected to the first bidirectional screw, and the piston rod of the adjusting cylinder is connected to the sliding seat that is slidably connected to the first bidirectional screw.

[0008] In one specific implementation, the adjusting component further includes a second bidirectional screw and two gears. The second bidirectional screw is located within the slide groove and is arranged parallel to the first bidirectional screw. Both ends of the second bidirectional screw are rotatably connected to the lifting plate. Each of the two gears corresponds to the first bidirectional screw and the second bidirectional screw. The gear corresponding to the first bidirectional screw is coaxially fixed to the first bidirectional screw, and the gear corresponding to the second bidirectional screw is coaxially fixed to the second bidirectional screw, with the two gears meshing with each other. The sliding seat, which is slidably connected to the first bidirectional screw, is threadedly connected to the second bidirectional screw.

[0009] In one specific implementation, the trenching assembly further includes a plurality of fixing members, each corresponding to one of the trenching members. The fixing members are connected to the lifting plate and are used to fix the lifting plate and the sliding seat.

[0010] In one specific implementation, the fixing member includes two fixing screws, each corresponding to a sliding seat, and the fixing screws are sequentially inserted into the lifting plate and the sliding seat.

[0011] In one specific implementation, a leveling component is also included, the leveling component comprising a leveling element, the leveling element comprising at least one leveling plate connected to the lifting plate, the bottom of the leveling plate being in contact with the ground.

[0012] In one specific implementation, there are two flat plates, which form a dihedral angle and are hinged together on one side close to each other, with the opening of the dihedral angle facing the side of the transfer component. The leveling assembly also includes a guide member, which includes two leveling cylinders. Each of the two leveling cylinders is close to one of the leveling plates. The leveling cylinders are located from the lifting plate to one side of the leveling plate. The cylinder body of the leveling cylinder is connected to the lifting plate, and the piston rod of the leveling cylinder is hinged to the side of the leveling plate away from the hinge end.

[0013] Secondly, this application adopts a reseeding method for grassland ecological restoration, using the following technical solution: A method for reseeding grassland ecological restoration, using the aforementioned reseeding device, includes the following steps: S1: Preparation before operation: Select appropriate grass species and choose appropriate sowing spacing according to the existing vegetation type; S2: Equipment preparation: Move the grassland ecological restoration reseeding device to the reseeding area, and then, according to the specific sowing spacing, activate the adjusting component in the furrowing component to ensure that the multiple furrowing blades are also at a suitable spacing. Adjust the furrowing blades to contact the ground using the lifting component. S3: Precision seeding: Personnel push the grassland ecological restoration reseeding device to dig trenches and sow grass seeds into the trenches, achieving precision seeding; S4: Covering, compacting and leveling: Adjusting the position of the leveling board according to the sowing spacing with the adjusting device can flatten the grass.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. The designed grassland ecological restoration reseeding device and method first moves the device to the area to be reseeded. According to the sowing requirements of the grass seeds, a suitable sowing spacing is selected. The furrowing component is activated, and the adjusting component drives the sliding seat to adjust to the appropriate position. During this process, the furrowing blade moves synchronously with the sliding seat. Then, the furrowing blade is inserted into the ground, and the device moves in the specified direction to open furrows and sow grass seeds in the furrows. This helps to solve the problem of not being able to adapt to different seed sowing spacings.

[0015] 2. The designed grassland ecological restoration reseeding device and method, when it is necessary to adjust the sowing spacing according to the sowing requirements, the drive motor is started, and the drive motor drives the first bidirectional screw to rotate, which can make the two sets of sliding seats move towards or away from each other. After the two sets of sliding seats are adjusted to the appropriate position, the two adjusting cylinders are started at the same time. The adjusting cylinders push the sliding seats that are slidably connected to the first bidirectional screw to move, which can adjust the four sliding seats to the appropriate spacing. At this time, the four furrowing knives also have the appropriate spacing, which makes it easy to adjust the spacing of the sliding seats.

[0016] 3. The designed reseeding device and method for grassland ecological restoration features a discharge pipe that moves with the furrowing cutter via a sliding pipe, facilitating precise seeding of grass. Attached Figure Description

[0029] Reference Figure 1The container assembly 1 includes a storage box 11, a transfer component 12, and a handle 13. The storage box 11 is used to hold grass seeds. In this embodiment, the storage box 11 is a rectangular box with a narrowed bottom. The transfer component 12 is located at the bottom of the storage box 11. The transfer component 12 includes a support frame 121 and multiple casters 122. The support frame 121 is fixedly connected to the storage box 11 by screws.

The lifting component 21 is located on the side of the storage box 11 away from the handle 13. The lifting component 21 includes a fixed base 211, a lifting cylinder 212, and a lifting plate 213. The fixed base 211 is located at the bottom of the storage box 11 and is fixedly connected to the storage box 11 by screws.

The length direction of the lifting plate 213 is perpendicular to the length direction of the groove. A sliding groove 2131 is provided on the side of the lifting plate 213 near the narrowed opening of the storage bin 11. The groove 2131 is opened along the setting direction of the lifting plate 213. In this embodiment, the longitudinal section of the groove 2131 is T-shaped. Multiple sets of groove opening members 22 are spaced apart along the setting direction of the groove 2131. In this embodiment, there are two sets of groove opening members 22. Each set of groove opening members 22 includes two sliding seats 221 and two groove opening cutters 222.

As the personnel push the storage box 11 to move, the trenching blade 222 can open trenches on the ground for sowing grass seeds.

[0031] Reference Figure 2 and Figure 3In one embodiment, the adjusting component 23 includes a first bidirectional screw 231, a drive motor 232, and multiple adjusting cylinders 233. The first bidirectional screw 231 is located within a slide groove 2131, and the orientation of the first bidirectional screw 231 is consistent with the opening direction of the slide groove 2131. Both ends of the first bidirectional screw 231 are rotatably connected to the lifting plate 213. The housing of the drive motor 232 is fixedly connected to the lifting plate 213 by screws, and the drive motor 232 is close to one end of the first bidirectional screw 231. The output shaft of the drive motor 232 is coaxially fixed to one end of the first bidirectional screw 231 by a coupling. The drive motor 232 drives the first bidirectional screw 231 to rotate. Multiple sets of grooved parts 22 are evenly distributed on the first bidirectional screw 231. A sliding seat 221 away from the middle of the lifting plate 213 is slidably connected to the first bidirectional screw 231, and a sliding seat 221 close to the middle of the lifting plate 213 is threadedly connected to the first bidirectional screw 231. The adjusting cylinders 233 are connected to the first bidirectional screw 231. Each set of sliding seats 221 corresponds to a single sliding seat. The setting direction of the adjusting cylinder 233 is consistent with the setting direction of the trough 2131. The cylinder body of the adjusting cylinder 233 and the sliding seat 221 threadedly connected to the first bidirectional screw 231 are fixedly connected by screws. The piston rod of the adjusting cylinder 233 and the sliding seat 221 slidably connected to the first bidirectional screw 231 are also fixedly connected by screws. When it is necessary to adjust the spacing between the furrowing blades 222, firstly, according to the sowing requirements, the drive motor 232 is started. The drive motor 232 drives the first bidirectional screw 231 to rotate, which enables the two sets of furrowing parts 22 to move towards or away from each other. After the furrowing parts 22 are adjusted to the appropriate position, the two adjusting cylinders 233 are started at the same time. The adjusting cylinders 233 push the sliding seat 221 slidably connected to the connecting plate to move, which can adjust the four sliding seats 221 to the appropriate spacing. At this time, the four furrowing blades 222 also have the appropriate spacing, which is convenient for digging furrows and can adapt to different sowing spacings.

[0032] Reference Figure 3 and Figure 4In another embodiment, the adjusting component further includes a second bidirectional screw 234 and two gears 235. The second bidirectional screw 234 is located within the slide groove 2131 and is arranged parallel to the first bidirectional screw 231. The second bidirectional screw 234 is located on the side of the first bidirectional screw 231 near the top of the lifting plate 213. Both ends of the second bidirectional screw 234 are rotatably connected to the lifting plate 213. The two gears 235 correspond to the first bidirectional screw 231 and the second bidirectional screw 232, respectively. The gear 235 corresponding to the first bidirectional screw 231 is coaxially welded to the first bidirectional screw 231 and the gear 235 corresponding to the second bidirectional screw 232. The gear 235 corresponding to the screw 234 is coaxially welded to the second bidirectional screw 234, and the two gears 235 mesh with each other.

The sliding seat 221, which is slidably connected to the first bidirectional screw 231, is threadedly connected to the second bidirectional screw 234. By driving the first bidirectional screw 231 and the second bidirectional screw 234 to rotate by the drive motor 232, the spacing between multiple sliding seats 221 can be adjusted, thereby adjusting the spacing of the grooving cutter 222. When multiple sets of grooving parts 22 are required, the two implementation schemes can also be used in combination.

The push net 322 can push stones on the grass, causing the stones to roll onto the push net 322, making it easier for personnel to push the storage box 11 for sowing grass seeds. The outer side of the push net 322 is fitted with a protective frame 3221 to prevent the edges from curling due to repeated collisions with stones. When the device is not in use, the rotating rod 321 is rotated to facilitate the storage of the push net 322. The rotating motor 323 is located near one end of the rotating rod 321.

The guide element 52 includes two leveling cylinders 521, each close to one leveling plate 511. The leveling cylinders 521 are powered by water spray. The pipe is installed on one side of the leveling plate 511. The cylinder body of the leveling cylinder 521 is hinged to the support frame 121. The piston rod of the leveling cylinder 521 is hinged to the side of the leveling plate 511 away from the hinge end. The leveling cylinder 521 pushes the leveling plate 511 to move, thereby adjusting the angle of the dihedral. This allows for adjustments based on different sowing spacings. When the sowing spacing is large, two leveling cylinders 521 are activated simultaneously. The leveling cylinders 521 push the two leveling plates 511, increasing the angle of the dihedral. The leveling plate 511 moves with the device, covering the surrounding soil to facilitate the survival of grass seeds.

[0040] The implementation principle of a grassland ecological restoration reseeding device according to an embodiment of this application is as follows: When the grassland ecological restoration reseeding device is needed, firstly, the device is moved to the area to be reseeded. Personnel place the grass seeds to be sown in the storage box 11. According to the sowing requirements, the furrowing component 2 is activated. The adjusting component 23 adjusts the multiple furrowing components 22 to a suitable spacing. During this process, the discharge component 14 in the covering component 4 moves synchronously with the furrowing component 22 to facilitate smooth sowing. According to the sowing spacing, the position of the leveling plate 511 is adjusted by the guide component 52. Subsequently, the lifting component 21 is activated, which enables the furrowing blade 222 in the furrowing component 22 to contact the ground. Personnel push the device to move, which enables the furrowing blade 222 to open furrows on the ground. The grass seeds in the storage box 11 fall into the furrows along the discharge pipe 141. The covering component 42 covers the grass seeds with fine soil. Then, the water spraying component 43 provides nutrients to the grass seeds. Finally, the leveling component 51 in the leveling component 5 moves with the device to flatten the grassland.

[0041] When the sowing spacing needs to be adjusted according to the sowing requirements, the drive motor 232 is started. The drive motor 232 drives the first bidirectional screw 231 to rotate, which enables the two sets of sliding seats 221 to move closer to or further away from each other. After the two sets of sliding seats 221 are adjusted to the appropriate position, the two adjusting cylinders 233 are started at the same time. The adjusting cylinders 233 push the sliding seats 221 that are slidably connected to the first bidirectional screw 231 to move, which can adjust the four sliding seats 221 to the appropriate spacing. At this time, the four furrowing knives 222 also have the appropriate spacing.

[0042] Secondly, this embodiment discloses a reseeding method for grassland ecological restoration.

[0043] A reseeding method using a grassland ecological restoration reseeding device includes: S1: Preparation before operation: Select appropriate grass species and sowing spacing according to the original vegetation type, test the soil, collect soil compaction and moisture content of the reseeding area, screen the seeds and remove impurities and inferior seeds. S2: Equipment preparation: Move the grassland ecological restoration reseeding device to the reseeding area, place the selected grass seeds in the storage box 11, and then, according to the specific sowing spacing, start the adjusting component 23 in the furrowing component 2, drive the motor 232 to drive the first bidirectional screw 231 to rotate, and adjust the sliding seat 221 threadedly connected to the first bidirectional screw 231 to the appropriate position. Then, start the two adjusting cylinders 233 at the same time. The adjusting cylinders 233 push the sliding seat 221 slidably connected to the first bidirectional screw 231 to move, which can adjust the four sliding seats 221 to the appropriate spacing. At this time, the four furrowing blades 222 also have the appropriate spacing. The furrowing blades 222 are brought into contact with the ground by the lifting cylinder 212. S3: Precision seeding: Personnel hold handle 13 and push the grassland ecological restoration reseeding device to dig trenches. Grass seeds enter the trenches through discharge pipe 141. The flow rate of grass seeds is adjusted by the solenoid valves on discharge pipe 141 to achieve precision seeding. S4: Soil covering and compaction: After precise sowing, the fine soil in the soil covering box 42 falls into the trench through the soil covering pipe 422, making close contact with the grass seeds. Then, water is sprayed into the trench through the water spraying device 43 to provide nutrients for the grass seeds. S5: Leveling: According to the sowing spacing, the position of the leveling plate 511 is adjusted by the adjusting component 23. The leveling component 51 in the leveling assembly 5 moves with the device and can flatten the grass.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
