Technical Field
[0001] This invention relates to the field of seeding technology, specifically to a reseeding device for grassland restoration. Background Technology
[0002] Grassland degradation refers to a series of degradation phenomena in grassland ecosystems, such as soil deterioration and changes in species structure. The causes of grassland degradation can be mainly divided into human factors and natural factors. Human factors mainly include overgrazing, unreasonable reclamation, and industrial construction, while natural factors mainly include climate change, biological invasion, and soil characteristics. With the continuous development of society, grassland degradation is constantly intensifying. Therefore, reseeding in degraded grassland areas is an important measure.
[0003] While reseeding devices for grassland degradation restoration are widely used in this field, they still have several drawbacks, including: Traditional reseeding devices cause healthy vegetation to be crushed by the tires during operation, potentially leading to its death. Furthermore, the continuous path of the tires can create isolated vegetation islands, hindering grassland restoration. Additionally, traditional reseeding methods typically involve creating trenches on the soil surface and burying seeds in them, which can damage the roots and stems of surrounding healthy vegetation, causing it to die.
[0004] To address the above problems, a reseeding device for grassland restoration is proposed. Summary of the Invention
[0005] The purpose of this invention is to provide a reseeding device for grassland restoration. By using this device, the problem of "vegetation islands" caused by the tires crushing healthy vegetation and forming continuous paths during the operation of traditional reseeding devices is solved. In addition, it also solves the problem of damage to the roots and stems of surrounding healthy vegetation caused by traditional trenching reseeding methods, which leads to the death of healthy vegetation is solved.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

This not only reduces the workload but also saves seeds.
[0017] 2. The present invention adopts a cross-shaped and intermittent path, which avoids the situation of a large area of soil being compacted continuously, maintains soil aeration, and is conducive to the normal growth of healthy vegetation.
[0018] 3. Because the compaction path of this invention is intermittent and cross-shaped, rather than continuous, it can maintain the continuity of vegetation, avoid the phenomenon of "vegetation islands", and help maintain the stability of grassland ecology.
[0019] 4. This invention can achieve dynamic adaptive switching between reseeding and raking, enabling reseeding and raking to be carried out simultaneously, which greatly improves work efficiency.
[0020] 5. This invention uses a dispersing component to scatter the withered grass, which can prevent large areas of withered grass from gathering together and affecting the normal growth of vegetation.
[0021] 6. This invention integrates the reseeding function with the grass-raking function, reducing the number of times mechanical equipment walks on the grassland, thereby reducing disturbance to the grassland ecology, improving the seed germination rate, and thus facilitating the self-repair of the grassland.
[0022] 7. This invention uses the method of inserting seeds into the soil for reseeding, which reduces disturbance and damage to the roots and stems of healthy vegetation compared to the existing trenching reseeding method, and also helps to improve the self-repair of grassland.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0026] To address the technical problem of traditional reseeding devices causing "vegetation islands" by having tires compact healthy vegetation and create continuous paths during operation, such as... Figures 1-12 As shown, the following preferred technical solutions are provided: like Figures 1-2As shown, a reseeding device for grassland restoration includes a body 1. A visual probe 2 for monitoring grassland degradation is installed on the front side wall of the body 1. A power component 3 for providing power output is fixedly installed on the top surface of the body 1. A water tank 4 for cooling the power component 3 is also fixedly installed on the top surface of the body 1. A support component 5 for maintaining the stability of the reseeding device is fixedly installed on the rear side wall of the body 1. A seed storage box 6 for storing seeds is fixedly installed on the top surface of the support component 5. A cover 60 is fixedly installed on the top of the seed storage box 6, and a feed inlet is provided on the cover 60, which not only facilitates feeding but also prevents seeds from spilling out during reseeding and causing waste. A lifting component 7 is fixedly installed on the bottom surface of the support component 5. A reseeding component 8 for reseeding is fixedly installed on the lifting component 7. The lifting component 7 controls the height of the reseeding component 8, and the reseeding component 8 is connected to the seed storage box 6. Figure 3 As shown, several dispersing components 10 for scattering dry grass are slidably installed on the lower part of the machine body 1. The dispersing components 10 are movably connected to the lifting components 7 via connecting rods 50. A limiting frame 9 for limiting the connecting rods 50 is fixedly installed on the lower side wall of the rear end of the machine body 1, and the connecting rods 50 and the limiting frame 9 are movably connected, as shown. Figure 2 As shown, the lower part of the machine body 1 is rotatably equipped with a traveling component 20 for driving the reseeding device to move, and the traveling component 20 is connected to the power component 3 by a belt. The traveling component 20 has several avoidance components 40 for avoiding healthy vegetation. The lower part of the machine body 1 is also rotatably equipped with a toggle component 30 for driving the dispersing component 10 to swing back and forth, and the toggle component 30 is connected to the traveling component 20 by a belt.
[0027] Specifically, before reseeding the grassland, the reseeding device is first firmly supported on the ground by the support component 5, and then the seeds are placed in the storage box 6 for storage. After the seeds are placed, the staff holds the seeding device and then starts the power component 3. The power component 3 drives the traveling component 20 through the belt, which in turn drives the reseeding device forward. During the forward movement of the reseeding device, the distribution of healthy vegetation around the grassland in front is monitored in real time by the vision probe 2. The vision probe 2 transmits the monitored healthy vegetation distribution data to the controller (not shown in the figure). After analyzing the healthy vegetation distribution data, the controller (not shown in the figure) can start to dynamically adjust the avoidance component 40 on the traveling component 20 to ensure that the traveling component 20 minimizes the crushing of healthy vegetation during its movement. Moreover, by dynamically adjusting the avoidance component 40, the crushing path of the traveling component 20 is crisscrossed and intermittent, rather than continuous, reducing the damage to healthy vegetation during the reseeding process and helping to maintain the stability of the grassland ecosystem.
[0028] In addition, during the reseeding device's forward movement, the visual probe 2 can monitor the degradation status of the grassland in real time. When the grassland has not yet reached a degradation point, the lifting component 7 is in a retracted state. Therefore, the reseeding component 8 is in its initial position and does not contact the soil. At this time, the dispersing component 10 is close to the ground but does not contact the ground. When the reseeding device moves forward, the dispersing component 10 can pull the withered grass scattered on the ground or covering the vegetation. Furthermore, since the actuating component 30 and the traveling component 20 are connected by a belt, when the traveling component 20 operates, it will drive the actuating component 30 to rotate via the belt. During the rotation of the actuating component 30, it will intermittently apply pressure to the dispersing component 10. When the dispersing component 10 is under force... The device will swing up and down. Therefore, when the actuating component 30 rotates, it can drive the dispersing component 10 to swing back and forth. This allows the dispersing component 10 to shake the withered grass during the pulling process, preventing large patches of withered grass from gathering together and affecting the normal growth of vegetation. When it is about to reach the degraded position, the lifting component 7 corresponding to the degraded position begins to extend, driving the reseeding component 8 to insert into the soil and bury the seeds in the storage box 6 into the soil. This process can be repeated to continuously reseed the degraded position until the reseeding is completed. The lifting component 7 then retracts and drives the reseeding component 8 to reset. During this process, only the lifting component 7 and the reseeding component 8 corresponding to the degraded position operate. The lifting components 7 and the reseeding component 8 at other positions do not operate.
[0029] The above settings enable dynamic reseeding, providing greater flexibility during use. Furthermore, dynamic reseeding reduces damage to surrounding vegetation while achieving efficient reseeding, thus promoting the ecological restoration of grasslands.
[0030] like Figure 3 As shown, the machine body 1 includes a frame 11. A front baffle 12 is fixedly installed on the top surface of the frame 11. The front baffle 12 can protect the frame 11. A vision probe 2 is fixedly installed on the outer side wall of the front end of the front baffle 12 for real-time monitoring of the degradation of the grassland in front and the condition of the surrounding healthy vegetation. A mounting plate 13 is fixedly installed at the bottom of the frame 11. Several vertical through grooves 14 are opened on the mounting plate 13. Several dispersing components 10 are correspondingly slidably installed inside the several through grooves 14. Through the restriction effect of the mounting plate 13 and the through grooves 14, the dispersing components 10 can only slide vertically inside the through grooves 14. Handrails 15 are fixedly installed on the outer walls on both sides of the frame 11. With the setting of the handrails 15, the operator can operate the reseeding device more conveniently.
[0031] like Figures 3-5As shown, the traveling component 20 includes a connecting shaft 201 that is rotatably mounted through the bottom of the frame 11. A pulley 202 is fixedly sleeved on the outer circumference of one end of the connecting shaft 201. The pulley 202 is connected to the power component 3 by a belt. Hubs 203 are fixedly mounted on both ends of the connecting shaft 201. A pair of wheel rims 204 are respectively provided on the outer ring of the two hubs 203. The wheel rims 204 and hubs 203 are fixedly connected by a number of spokes 206. A number of fixed shafts 205 are fixedly mounted between the two wheel rims 204. A second pulley 207 is fixedly sleeved on the outer circumference of the other end of the connecting shaft 201. The second pulley 207 is connected to the actuating component 30 by a belt.
[0032] The basic shape of the tire is formed by the combination of the hub 203, rim 204, spokes 206 and fixed shaft 205. When the power unit 3 drives the connecting shaft 201 to rotate through the belt and pulley 202, the hub 203, rim 204, spokes 206 and fixed shaft 205 will rotate synchronously with the connecting shaft 201, thereby achieving the travel effect of the reseeding device.
[0033] like Figure 5 As shown, the avoidance component 40 includes a fixed block 401 fixedly installed on the inner side wall of the wheel rim 204. An electric push rod 402 is fixedly installed on the side wall of the fixed block 401. A connector 404 is fixedly installed at the output end of the electric push rod 402. A rubber plate 403 is slidably sleeved on the outer circumference of the fixed shaft 205. The connector 404 is fixedly connected to the rubber plate 403. The electric push rod 402 can adjust the position of the rubber plate 403 on the fixed shaft 205 through the connector 404, thereby achieving the effect of avoiding healthy vegetation. The rubber plate 403 has a large contact area and high friction with the soil. When the rubber plate 403 cooperates with the traveling component 20, it can make the reseeding device move smoothly and reduce the phenomenon of slippage of the reseeding device.
[0034] Since the avoidance component 40 rotates synchronously with the traveling component 20 during the reseeding process, and since the electric push rod 402 requires electrical energy, in order to avoid the problem of wire entanglement, brushes (not shown in the figure) and conductive slip rings (not shown in the figure) are respectively installed at the rotating connection points of the frame 11 and the connecting shaft 201. This ensures that the traveling component 20 and the avoidance component 40 do not affect the transmission of electrical energy during rotation, thus overcoming the problem of wire entanglement. The conductive slip rings (not shown in the figure) and brushes (not shown in the figure) are existing technologies and will not be described in detail here.
[0035] Specifically, during the reseeding device's forward movement, the distribution of healthy vegetation around the grassland ahead is monitored in real time by a vision probe 2. The vision probe 2 transmits the monitored healthy vegetation distribution data to a controller (not shown in the figure). After analyzing the healthy vegetation distribution data, the controller (not shown in the figure) can dynamically adjust the position of the rubber plate 403 on the fixed shaft 205 by controlling the electric actuator 402 and the connector 404, thus avoiding healthy vegetation as much as possible and reducing damage to it. Figure 5 As shown, since several avoidance components 40 are arranged in an opposing and staggered manner, the rubber sheet 403 will not leave a continuous rolling path on the soil, which is not only conducive to the restoration of the grassland ecosystem, but also avoids the formation of "vegetation islands".
[0036] It should be noted that when the electric actuator 402 and the connector 404 dynamically adjust the position of the rubber plate 403 on the fixed shaft 205, the electric actuators 402 on the traveling components 20 on both sides of the reseeding device are simultaneously activated, driving the rubber plates 403 to adjust their positions on the fixed shaft 205 respectively. This ensures that the rubber plates 403 on both sides of the traveling components 20 are always in a symmetrical state, thereby providing uniform support force to the reseeding device. Ultimately, this allows the reseeding device to operate smoothly without uneven support force on both sides. This ensures that the reseeding component 8 maintains a consistent insertion depth when inserted into the ground, preventing inconsistent seed burial depths and guaranteeing a good reseeding effect.
[0037] Furthermore, this invention uses a vision probe 2 to scan the road conditions ahead in real time. Based on the vegetation conditions ahead, it can adjust the position of the rubber plate 403 on the fixed shaft 205 before the rubber plate 403 contacts the ground, avoiding jamming when adjusting the position after the rubber plate 403 contacts the ground. It also reduces wear on the rubber plate 403 and improves the stability of the device during movement. After the rubber plate 403 is adjusted on the fixed shaft 205 and contacts the ground, and then leaves the ground again, the electric push rod 402 will drive the rubber plate 403 to move a certain distance in the direction of rubber plate 403 reset through the connector 404. This increases the gap between the rubber plate 403 and the wheel rim 204, preventing stones or mud from getting stuck in the gap, so that subsequent dynamic adjustments can be made. By repeating the above steps, continuous dynamic adjustment can be achieved.
[0038] The specific effects of the above settings are as follows: 1. Compared to the traditional method where the entire tire tread is rolled over the vegetation, this invention, by adjusting the position of the rubber plate 403 and the opposing and staggered arrangement of the avoidance components 40 during the forward movement, can minimize the rolling over of healthy vegetation, thereby reducing the number of reseedings, reducing workload, and saving seeds; 2. The use of a crisscross and intermittent path prevents large areas of soil from being compacted continuously, maintaining soil aeration and promoting the normal growth of healthy vegetation; 3. Because the rolling path is crisscross and intermittent, rather than continuous, it maintains the continuity of vegetation and avoids the phenomenon of "vegetation islands." Since "vegetation islands" are relatively unstable and easily affected by external factors, the crisscross and intermittent rolling path helps maintain the stability of the grassland ecosystem.
[0039] To address the problems of traditional trenching reseeding methods that damage the roots and stems of surrounding healthy vegetation, leading to its death, and the inability to simultaneously rake grass during reseeding, such as... Figure 3 and Figures 6-12 As shown, the following preferred technical solutions are provided: like Figure 3 As shown, the support assembly 5 includes a load-bearing plate 51 fixedly installed on the rear side wall of the frame 11, which is mainly used to fix the storage box 6 and the lifting assembly 7. A pair of support rods 52 are fixedly installed on the bottom surface of the load-bearing plate 51. A connecting plate 53 is fixedly installed at the lower end of the two support rods 52. A pair of auxiliary wheels are rotatably installed at the bottom of the connecting plate 53. The support rods 52 are mainly used to support the reseeding device, so that the reseeding device can stand stably. Since the auxiliary wheels are small in size, they have little impact on the vegetation. Even if the compaction path is continuous, there will be no "vegetation islands".
[0040] The lifting assembly 7 includes a U-shaped frame 71 fixedly installed on the bottom surface of the load-bearing plate 51. Several electric telescopic columns 72 are fixedly installed on the U-shaped frame 71. The output end of the electric telescopic column 72 is installed through the U-shaped frame 71, and the output end of the electric telescopic column 72 is fixedly installed with a mounting ear 73. When the vision probe 2 detects the location of grassland degradation, the controller (not shown) starts the electric telescopic column 72 corresponding to the degradation location to extend and drive the reseeding assembly 8 to insert into the soil, burying the seeds in the storage box 6 into the soil. Then the electric telescopic column 72 shortens and drives the reseeding assembly 8 to pull out of the soil. This process is repeated until the degradation location is completely reseeded.
[0041] like Figure 3As shown, the reseeding assembly 8 includes a seeding head 81 fixedly installed on the mounting ear 73. The seeding head 81 is connected to the storage box 6 through a conveying pipe 82. During reseeding, the seeds in the storage box 6 will enter the seeding head 81 in a measured amount through the conveying pipe 82. Then, the electric telescopic column 72 extends and drives the seeding head 81 to insert into the soil and bury the seeds in the soil, thus realizing one sowing operation.
[0042] It should be noted that the seeds in the storage box 6 are quantitatively fed into the seed head 81 through the conveying pipe 82, which is existing technology and will not be described in detail here. Also, the bottom of the seed head 81 is openable. When the seed head 81 is inserted into the soil, the bottom of the seed head 81 is closed to prevent blockage. When it is inserted into the appropriate position, the bottom of the seed head 81 is opened to bury the seeds in the soil. There are many ways to open the bottom of the seed head 81, such as using pneumatic or linkage transmission, which are existing technologies and will not be described in detail here.
[0043] like Figure 3 , Figure 6 and Figure 8 As shown, the limiting frame 9 includes a pair of mounting rods 91 fixedly installed on the lower side wall of the rear end of the frame 11. A limiting shaft 92 is fixedly installed on both mounting rods 91, and the connecting rod 50 is rotatably sleeved on the outer circumference of the limiting shaft 92.
[0044] like Figure 9 and Figure 11 As shown, the dispersing component 10 includes a slider 101 that is embedded and slidably installed inside the through groove 14. Inside the slider 101, a rotating shaft 102 and a rotating shaft 103 are rotatably installed from top to bottom. One end of the connecting rod 50 is rotatably installed on the mounting ear 73, and the other end of the connecting rod 50 is fixedly sleeved on the outer circumference of the rotating shaft 102. A swing rod 104 is fixedly sleeved on the outer circumference of the rotating shaft 103. The swing rod 104 and the slider 101 are elastically connected by a torsion spring 105. A horizontal plate 106 is fixedly installed on the side wall of the swing rod 104 away from the actuating component 30. Several long rods 107 are horizontally fixedly installed on the side wall of the horizontal plate 106. Several teeth 108 are fixedly installed on the bottom surface of the several long rods 107 respectively.
[0045] like Figures 6-7 As shown, the actuation assembly 30 includes a rotating shaft 301 rotatably mounted on the lower part of the frame 11. A pulley 302 is fixedly sleeved on the outer circumference of the rotating shaft 301, and the pulley 302 and the pulley 207 are connected by a belt for transmission. Several levers 303 are also fixedly mounted on the outer circumference of the rotating shaft 301.
[0046] like Figures 10-12As shown, the lever 303 includes a cylindrical body 3031 fixedly installed on the outer circumferential wall of the rotating shaft 301. The cylindrical body 3031 has an installation cavity 3032 inside. A sliding column 3033 is slidably installed inside the installation cavity 3032. The side wall of the sliding column 3033 and the inner wall of the installation cavity 3032 are elastically connected by a spring 3036. A permanent magnet 3034 is fixedly installed on the side wall of the sliding column 3033. An electromagnet 3035 is fixedly installed on the inner wall of the installation cavity 3032, and the installation cavity 3032 and the electromagnet 3035 are aligned.
[0047] During the re-seeding process, the actuating component 30 rotates continuously. Since the electromagnet 3035 requires electrical energy, in order to avoid the problem of wire entanglement, a brush (not shown in the figure) and a conductive slip ring (not shown in the figure) are respectively provided at the rotation connection between the frame 11 and the rotating shaft 301. This ensures that the actuating component 30 does not affect the transmission of electrical energy during rotation, thus overcoming the problem of wire entanglement. The conductive slip ring (not shown in the figure) and the brush (not shown in the figure) are both existing technologies and will not be described in detail here.
[0048] Specifically, as the reseeding device moves forward, the visual probe 2 can also monitor the degradation of the grassland in front in real time, which can be divided into the following two situations: Scenario 1: When the grassland has not yet reached the degradation stage, the lifting component 7 is in a retracted state. Therefore, the seeding head 81 is in its initial position and does not contact the soil. At this time, the teeth 108 on the dispersing component 10 are close to the ground but not in contact with it. When the reseeding device moves forward, the teeth 108 pull the withered grass scattered on the ground or covering the vegetation. Since the actuating component 30 and the traveling component 20 are connected by a belt, when the traveling component 20 is running, the pulley 207 will drive the pulley 302 and the rotating shaft 301 to rotate synchronously via the belt. During the rotation of the rotating shaft 301, pressure will be applied to the swing rod 104 through the sliding column 3033. When the sliding column 3033 contacts the swing rod 104, the swing rod 104 will drive the rotating shaft 103, the horizontal plate 106, the long rod 107 and the teeth 108 to flip on the slider 101, so that the teeth 108 carry the withered grass upward. When the swing rod 104 reaches its maximum tilt angle, the rotating shaft 301 continues to rotate, increasing the interaction force between the sliding column 3033 and the swing rod 104. This causes the sliding column 3033 to retract into the mounting cavity 3032 and compress the spring 3036. When the sliding column 3033 passes the swing rod 104, it pops out and resets under the elastic force of the spring 3036. At the same time, the swing rod 104, under the elastic force of the torsion spring 105, drives the rotating shaft 103, the horizontal plate 106, the long rod 107, and the teeth 108 to flip and reset in the opposite direction on the slider 101. This process repeats, causing the dispersing assembly 10 to swing back and forth. This allows the teeth 108 to shake the withered grass apart during the pulling process, preventing large patches of withered grass from gathering together and affecting the normal growth of vegetation.
[0049] Scenario 2: When the plant is about to reach the degraded position, the electric telescopic column 72 corresponding to the degraded position begins to extend, driving the seeding head 81 to insert into the soil and bury the seeds in the storage box 6. This process is repeated to continuously re-seed the degraded position until the re-seeding is completed. The lifting component 7 then retracts and drives the seeding head 81 to reset. During this process, only the electric telescopic column 72 and seeding head 81 corresponding to the degraded position operate; the electric telescopic columns 72 and seeding heads 81 at other positions do not operate. Simultaneously, as the electric telescopic column 72 extends and... As the seed head 81 moves downward, the electric telescopic column 72 applies pressure to the connecting rod 50 through the mounting lug 73. Using the lever principle, the connecting rod 50 drives the dispersing component 10 to slide upward inside the through groove 14, causing the dispersing component 10 to move away from the ground and stop dispersing the withered grass. After the reseeding is completed, the electric telescopic column 72 drives the seed head 81 to move upward and reset. Again, using the lever principle, the connecting rod 50 drives the dispersing component 10 to slide downward and reset inside the through groove 14, restoring the function of dispersing the withered grass.
[0050] To prevent the dispersing component 10 from colliding with the sliding column 3033 during its upward movement, the electromagnet 3035 is energized, causing it to attract the permanent magnet 3034. This causes the sliding column 3033 to retract into the mounting cavity 3032. At this time, when the rotating shaft 301 rotates the sliding column 3033, the sliding column 3033 will not contact the swing rod 104, thus preventing a collision. If the reseeding is finished and the grass-raking function needs to be restored, the electromagnet 3035 is de-energized, causing the sliding column 3033 to pop out and reset under the elastic force of the spring 3036. At this time, when the rotating shaft 301 rotates the sliding column 3033, the sliding column 3033 will contact the swing rod 104 again, thus restoring the up-and-down reciprocating swing of the dispersing component 10 and continuing to scatter the dry grass.
[0051] When the connecting rod 50 drives the dispersing component 10 to slide inside the through groove 14, the connecting rod 50 makes a circular motion while the dispersing component 10 makes a linear motion. Therefore, a distance difference will occur between the connecting rod 50 and the dispersing component 10 during operation. To overcome this problem, the connecting rod 50 is made telescopic.
[0052] Traditional reseeding devices only focus on achieving the reseeding effect, and dry grass requires separate equipment for processing. However, this invention can achieve dynamic adaptive switching between reseeding and raking. When reseeding is needed, the raking action stops, and when reseeding is not being carried out, the raking action starts, so that reseeding and raking can be carried out simultaneously, which greatly improves work efficiency. Moreover, by scattering the dry grass through the dispersing component 10, it can prevent large areas of dry grass from gathering together and affecting the normal growth of vegetation.
[0053] In addition, integrating the reseeding and hay-raking functions reduces the number of times machinery travels on the grassland, thereby reducing disturbance to the grassland ecosystem, increasing seed germination rate, and thus facilitating grassland self-repair.
[0054] Reseeding by inserting seeds into the soil reduces disturbance and damage to the roots and stems of healthy vegetation compared to existing trenching methods, and also helps improve the self-repair of grasslands.
