Description

TECHNICAL FIELD

[0001] The present application relates to a vegetation restoration device, in particular to a steep slope ecological restoration device based on ecological protection. BACKGROUND

[0002] Slope ecological restoration is a key link in vegetation restoration engineering, especially in the slope management of highway, railway, mine, water conservancy and other engineering construction. Its core goal is to effectively prevent soil erosion, enhance the ecological stability of the slope, and promote the natural recovery of the damaged ecological system through scientific vegetation reconstruction and soil improvement technology. Among the many vegetation restoration methods, seeding technology has become the main means of steep slope greening due to its efficiency and adaptability. This technology realizes rapid vegetation coverage and ecological restoration by uniformly spraying mixed materials such as plant seeds, nutrient medium, water-retaining agent and adhesive on the slope surface.

[0003] However, the existing seeding technology has the following problems when working on steep slopes. First, for seeding equipment that needs to walk on the slope, due to the large slope angle, the traditional seeding equipment is prone to displacement or overturning during operation, which not only affects the safety of construction, but also may cause the interruption of seeding and reduce the efficiency of operation. Second, the existing seeding equipment relies on high-pressure injection, which can achieve long-distance delivery, but the seeding range and material distribution are difficult to accurately control, resulting in uneven vegetation coverage on the slope, low seed germination rate, and affecting the long-term ecological restoration effect. In addition, under the condition of wind interference, the seeding materials are easy to drift, causing resource waste and pollution to the surrounding environment, further restricting the economy and applicability of the seeding technology.

Detailed Implementation

[0027] Example 1: An ecological restoration device for steep slopes based on ecological protection, such as... Figure 1 , Figure 2 and Figure 10 As shown, the system includes a greening operation vehicle 1, a seed box 2, a seed hopper cover 21, an electric rotating ring 3, a telescopic mechanism 4, a reciprocating mechanism 5, a sowing mechanism 6, and a traction mechanism 7. The seed box 2 is fixedly installed at the center of the top of the greening operation vehicle 1. The seed box 2 has inclined surfaces 22 on both the front and rear sides of its bottom surface, allowing the material to automatically concentrate towards the center. The seed hopper cover 21 is hinged to the top of the seed box 2 to prevent external impurities from entering and to avoid material spillage during movement. A discharge port 23 is located on the left side of the seed box 2, at the bottommost point of the seed box 2. The seed box 2 is positioned to ensure smooth material discharge. An electric rotating ring 3 is installed on the top of the seed box 2. A telescopic mechanism 4 is installed at an angle on the top of the electric rotating ring 3. A reciprocating mechanism 5 is installed on the upper end of the telescopic mechanism 4 to drive the sowing mechanism 6 to reciprocate along a certain path, thereby expanding the sowing coverage area. The sowing mechanism 6 is connected to the greening operation vehicle 1 and the reciprocating mechanism 5 to achieve uniform sowing operations on the slope area. A traction mechanism 7 is installed on the right end of the greening operation vehicle 1. The traction mechanism 7 is connected to the greening operation vehicle 1 through a transmission. The traction mechanism 7 automatically extends and retracts to adjust its length as the greening operation vehicle 1 moves.

[0028] This restoration device achieves soil stabilization and vegetation reconstruction through mechanized sowing. When performing ecological restoration sowing on steep slopes, first open the seed hopper cover 21 on top of the seed box 2, pour the required sowing material into the seed box 2, and then close the seed hopper cover 21 to prevent impurities from entering and ensure that the material does not spill during movement. Connect the traction mechanism 7 to the slings of an external crane, using the crane to provide auxiliary traction for the entire restoration device. Start the greening vehicle 1, allowing it to slowly climb up the steep slope from bottom to top. Because the traction mechanism 7 and the greening vehicle 1 are connected by a transmission, the traction mechanism 7 can extend and retract during the movement of the greening vehicle 1 to maintain a stable traction force from the crane on the restoration device, ensuring safe operation. When the greening vehicle 1 begins to move upwards from the bottom of the slope, start the sowing mechanism 6 and the reciprocating mechanism 5 to work together. The sowing mechanism 6 evenly sprays the material from the seed box 2 onto the slope surface. Simultaneously, the reciprocating mechanism 5 drives the sowing mechanism 6 to reciprocate back and forth on the guide frame 51, effectively expanding the sowing coverage area and improving operational efficiency and coverage. As the greening vehicle 1 continues to ascend, the traction mechanism 7 gradually retracts, maintaining traction with the crane to ensure the stable ascent of the repair device and prevent safety hazards caused by slipping due to gravity. When the greening vehicle 1 reaches the top of the slope, the crane lifts the entire repair device and transfers it to one side of the already sown area to prepare for subsequent downward sowing operations. To prevent the repair device from crushing and damaging the already sown area during downward movement, the electric rotating ring 3 can be activated to rotate the upper telescopic mechanism 4, reciprocating mechanism 5, and sowing mechanism 6 by 180 degrees, positioning the sowing mechanism 6 above the traction mechanism 7. Subsequently, the telescopic mechanism 4 is extended, driving the reciprocating mechanism 5 and sowing mechanism 6 to move outward, extending the sowing mechanism 6 beyond the traction mechanism 7, ensuring that the sowing position is not obstructed, thus achieving a second sowing operation from top to bottom without affecting the already sown area.

[0029] Example 2: Based on Example 1, such as Figure 1 and Figure 3As shown, the telescopic mechanism 4 includes a guide tube 41, a sliding frame 42, a connecting plate 43, a rotating shaft 44, a driver 45, a cylindrical gear 46, and a rack 47. Two guide tubes 41 are provided, with their lower ends symmetrically fixed to the top sides of the electric rotating ring 3. The guide tubes 41 are inclined, and the sliding frame 42 is slidably connected within both guide tubes 41. The sliding frame 42 can reciprocate vertically within the guide tubes 41, thereby achieving the lifting and lowering adjustment function. The upper ends of the two guide tubes 41 are connected by a connecting plate 43. The rotating shaft 44 is rotatably mounted on the connecting plate 43 along its length via a bearing seat. The driver 45... The system includes a servo motor, a worm gear, and a worm wheel. The servo motor is mounted in the middle of the mounting plate, and the worm gear is connected to the output shaft of the servo motor. A worm wheel that meshes with the worm gear is fitted in the middle of the rotating shaft 44. Cylindrical gears 46 are connected to both the front and rear ends of the rotating shaft 44. Through holes are opened in the upper part of the two guide tubes 41, and the cylindrical gears 46 are partially embedded in the through holes. A rack 47 is embedded in the side of the sliding frame 42 near the cylindrical gears 46. The cylindrical gears 46 mesh with the rack 47. When the servo motor drives the rotating shaft 44 to rotate, the cylindrical gears 46 rotate accordingly and mesh with the rack 47, thereby driving the sliding frame 42 to move up and down along the guide tubes 41 to achieve the telescopic action.

[0030] Before sowing, the servo motor in the driver 45 is started. The output shaft of the servo motor drives the worm gear to rotate, and the worm gear meshes with the worm wheel, causing the rotating shaft 44 to rotate synchronously. The cylindrical gears 46, which are fixedly connected to the front and rear ends of the rotating shaft 44, rotate accordingly and mesh with the rack 47 on the sliding frame 42, thereby driving the sliding frame 42 to move up and down along the guide tube 41. By controlling the forward and reverse rotation of the servo motor, the sliding frame 42 can be raised or lowered, thereby driving the reciprocating mechanism 5 and the sowing mechanism 6 to adjust their height and extend outward to meet the needs of different sowing ranges. When the sowing mechanism 6 is adjusted to the appropriate position, the servo motor is turned off. At this time, due to the self-locking characteristic of the worm gear transmission, the sliding frame 42 and its connecting parts can maintain their current position stably without power, thereby achieving reliable positioning support.

[0031] like Figure 1 and Figure 4As shown, the reciprocating mechanism 5 includes a guide frame 51, a belt drive mechanism 52, a moving frame 53, and rollers 54. The upper end of the sliding frame 42 is horizontally connected to the guide frame 51, which extends horizontally in the front-back direction. The moving frame 53 is slidably mounted on the guide frame 51. The belt drive mechanism 52 is provided on the guide frame 51 to drive the moving frame 53 to move back and forth periodically, thereby achieving uniform coverage of the sowing operation. Roller assemblies 54 are symmetrically arranged on the upper and lower sides of the moving frame 53, with six rollers 54 installed on each side. The rollers 54 are arranged in groups of three, symmetrically distributed front and back. The rollers 54 are in contact with the guide frame 51. Limit switches are provided at both the front and rear ends of the guide frame 51 to detect the limit position of the moving frame 53 and provide feedback signals when the set stroke endpoint is reached, controlling the belt drive mechanism 52 to reverse the operation, thereby achieving automatic cyclic reciprocating control.

[0032] like Figure 1 and Figure 4 As shown, the sowing mechanism 6 includes a seed delivery pump 61, a hose 62, a discharge pipe 63, a sowing nozzle 64, and a clamp 65. The seed delivery pump 61 is installed on the top left side of the greening operation vehicle 1. The inlet of the seed delivery pump 61 is connected to the outlet 23 on the left side of the seed box 2 through a pipe. The outlet of the seed delivery pump 61 is connected to the hose 62. The end of the hose 62 away from the seed delivery pump 61 is connected to the discharge pipe 63. The sowing nozzle 64 is installed at the lower end of the discharge pipe 63. The lower end of the sowing nozzle 64 extends to the left and right sides to expand the sowing width and improve the operation efficiency. The clamp 65 is connected to the moving frame 53. The discharge pipe 63 is detachably installed with the moving frame 53 through the clamp 65, which facilitates quick replacement or maintenance of the hose 62, the discharge pipe 63, and the sowing nozzle 64.

[0033] After height adjustment, the seed material delivery pump 61 is activated. The pump draws the seed material from the seed box 2 through the inlet pipe and delivers it sequentially through the hose 62 and outlet pipe 63 to the seed nozzle 64, ultimately spraying it evenly onto the target slope surface. Simultaneously, to expand the sowing coverage and improve uniformity, the belt drive mechanism 52 is activated. This mechanism drives the moving frame 53 to reciprocate along the guide frame 51. The rollers 54 roll against the guide frame 51, reducing resistance and ensuring smooth movement. When the moving frame 53 reaches its limit position, a limit switch is triggered at its end. Upon receiving the signal, the control system immediately reverses the belt drive mechanism 52, thus reversing the movement of the moving frame 53. Through the coordinated action of the two limit switches, the moving frame 53 can automatically cycle within a set range without manual intervention, improving sowing efficiency and automation.

[0034] Example 3: Based on Example 2, such as Figure 1 , Figure 5 ,Figure 6 and Figure 7 As shown, the traction mechanism 7 includes a support plate 71, a rope wheel 72, a connecting shaft 73, a disconnectable transmission assembly 74, a steel wire rope 75, a rope pulley 76, and a lifting lug 77. There are two support plates 71, which are respectively connected to the upper and lower sides of the right end of the seed box 2. The rope wheel 72 is rotatably installed on the front and rear sides of the bottom of the upper support plate 71 for winding and guiding the steel wire rope 75. The driven wheel on the right rear side of the greening operation vehicle 1 is connected to the connecting shaft 73 through a coupling. The disconnectable transmission assembly 74 is installed on the connecting shaft 73 for controllable power transmission. The connecting shaft 73 is connected to the rope wheel 72 through the disconnectable transmission assembly 74, so as to drive the rope wheel 72 to rotate when needed to realize the traction action. A steel wire rope 75 is wound between the two rope wheels 72. The steel wire rope 75 is provided with a rope pulley 76 on the outside. The rope pulley 76 is equipped with a lifting lug 77 for connecting to external traction equipment.

[0035] Before sowing on a steep slope, first connect the lifting lug 77 on the traction mechanism 7 to the sling of an external crane, and then use the crane to hoist the repair device to a suitable position at the top of the slope. Next, start the electric rotating ring 3, which rotates the telescopic mechanism 4, reciprocating mechanism 5, and sowing mechanism 6 180 degrees, positioning the sowing mechanism 6 directly above the traction mechanism 7 to prevent crushing of the repaired area during subsequent sowing. Then, extend the telescopic mechanism 4, moving the reciprocating mechanism 5 and the sowing nozzle 64 to the right, positioning them above the right side of the support plate 71 to ensure the sowing area covers the target area. After adjusting the posture, start the greening vehicle 1 and slowly move it down the slope. As the greening vehicle 1 descends, its right rear driven wheel rotates, driving the connecting shaft 73 to rotate synchronously via the coupling. The connecting shaft 73 transmits power to the rope wheel 72 via the disengageable transmission assembly 74, thereby driving the rope wheel 72 to rotate and releasing the wire rope 75 wound around it. As the greening vehicle 1 moves downwards, the steel wire rope 75 is gradually released, ensuring the repair device remains effectively connected to the crane's sling, preventing slippage or overturning on steep slopes and guaranteeing operational safety. The lengths of the steel wire rope 75 released from the front and rear pulleys 72 may differ slightly, allowing the rope 75 to slide freely on the pulley 76 for automatic balance adjustment, maintaining the repair device's stable posture. Once the repair device reaches the bottom of the slope, the greening vehicle 1 is moved to the side of the already sown area, and then restarted to move upwards along the slope. At this time, the connecting shaft 73 continues to rotate and, through the disengageable transmission assembly 74, drives the pulley 72 to wind the steel wire rope 75 in the opposite direction, ensuring the repair device remains under control and does not disengage from the crane's traction. If the repair device is performing sowing operations in a gentler slope area, crane assistance is not required; the power transmission path between the connecting shaft 73 and the pulley 72 can be severed by disconnecting the disengageable transmission assembly 74. At this time, the movement of the greening vehicle 1 will not drive the rope wheel 72 to retract or extend the steel wire rope 75, and the traction mechanism 7 is in a non-working state, which does not affect normal operation.

[0036] like Figure 7 and Figure 8As shown, the disengageable transmission assembly 74 includes a first mating plate 741, guide bars 742, a second mating plate 743, a locking bolt 744, and a first bevel gear 745. The connecting shaft 73 has first mating plates 741 on both its front and rear outer sides. The connecting shaft 73 is not connected to the first mating plates 741. The first mating plates 741 are rotatably mounted on the lower support plate 71 via bearing seats. Multiple guide bars 742 are evenly spaced along the circumferential direction on both the front and rear sides of the connecting shaft 73. The outer sides of the multiple guide bars 742 are slidably connected to the second mating plate 743. The second mating plate 743 can slide and adjust its position along the direction of the guide bars 742. The first docking plate 741 and the second docking plate 743 have matching groove structures on their opposite sides. When the two are aligned, they can be engaged through the grooves to transmit power. A locking bolt 744 is threaded onto the second docking plate 743. By tightening the locking bolt 744, the second docking plate 743 and the first docking plate 741 can be firmly locked together to form a rigid connection. Conversely, by loosening the locking bolt 744 and removing the second docking plate 743, the two can be separated, realizing the disconnection function of the transmission system. The bottom of the first docking plate 741 and the rope wheel 72 on the same side are fixedly connected to the first bevel gear 745, and the two first bevel gears 745 mesh with each other.

[0037] When it is necessary to connect the rope pulley 72 to the connecting shaft 73, first loosen the locking bolt 744 on the second docking plate 743 with a wrench, then push the second docking plate 743 closer to the first docking plate 741, with the guide bar 742 acting as a guide. If the grooves of the second docking plate 743 and the first docking plate 741 are not aligned in the initial state, the first docking plate 741 can be manually rotated to adjust its angle so that the two match and achieve reliable docking. After docking is completed, tighten the locking bolt 744 to firmly fix the second docking plate 743 to the connecting shaft 73, forming a rigid connection between the second docking plate 743 and the first docking plate 741. At this time, the power generated by the rotation of the connecting shaft 73 can be transmitted to the first docking plate 741 through the guide bar 742 and the second docking plate 743, and further through the meshing of the first bevel gear 745 fixed at the bottom of the first docking plate 741 and the first bevel gear 745 at the bottom of the rope pulley 72, ultimately driving the rope pulley 72 to rotate synchronously, realizing the winding and unwinding control of the wire rope 75. When it is necessary to cut off the power transmission between the pulley 72 and the connecting shaft 73, the operator loosens the locking bolt 744 again and pulls the second mating plate 743 outward along the guide bar 742, completely separating it from the first mating plate 741. Then, the locking bolt 744 is tightened to lock the second mating plate 743 in the separated position. At this point, even if the connecting shaft 73 rotates, it cannot transmit power to the first mating plate 741 and the pulley 72, thus achieving the power disconnection function.

[0038] Example 4, based on Example 3, such as Figure 2 andFigure 7 As shown, the system also includes a seed mixer, which comprises a stirring rod 81 and a second bevel gear 82. The stirring rod 81 is horizontally positioned at the lower center of the seed box 2 and is rotatably mounted on the seed box 2 via bearings. Both ends of the stirring rod 81 extend outwards through the side wall of the seed box 2. The right end of the stirring rod 81 and the middle of the connecting shaft 73 are both fixedly connected to the second bevel gear 82. The two second bevel gears 82 mesh with each other, allowing the rotational motion of the connecting shaft 73 to be synchronously transmitted to the stirring rod 81, thereby achieving continuous stirring of the material inside the seed box 2. When the connecting shaft 73 rotates, the power is transmitted to the stirring rod 81 through the two meshing second bevel gears 82. During the rotation of the stirring rod 81, the sowing material inside the seed box 2 is continuously stirred, preventing material sedimentation or clumping, ensuring that the material remains in a uniform state during transportation, and improving sowing quality.

[0039] like Figure 6 As shown, it also includes a rotating drum 9 and a protective tube 10. Each rope wheel 72 has a rotating drum 9 on its outer side, which is rotatably connected to the bottom of the upper support plate 71. A protective tube 10 is connected to the right side of the rotating drum 9 and communicates with it. The protective tubes 10 on the front and rear sides are respectively fitted onto the outer sides of the wire ropes 75 of the two rope wheels 72. When the sowing nozzle 64 is positioned above the traction mechanism 7 for spraying operations, to prevent the sprayed material from adhering to the wire rope 75 and affecting the normal operation of the traction mechanism 7, the protective tube 10 effectively isolates the sowing area from the wire rope 75, preventing material from directly splashing onto the surface of the wire rope 75, thus ensuring the cleanliness and service life of the traction mechanism 7. Furthermore, as the greening vehicle 1 moves up and down on the slope, the wire rope 75 is continuously released or retracted on the rope wheels 72, and the angle between the horizontal planes of the wire ropes 75 on the two rope wheels 72 changes accordingly. To adapt to this change, the rotating drum 9 can rotate freely with the change in the angle of the wire rope 75.

[0040] like Figure 9 As shown, it also includes a protective cover 11 and an elastic band 12. The protective cover 11 is provided between the upper and lower support plates 71 to provide external protection for the traction mechanism 7, preventing the intrusion of external impurities such as dust, debris and rainwater, and improving the adaptability and service life of the equipment in complex environments. The protective cover 11 has clearance holes on the front and rear sides of its right end to provide movement space for the protective tubes 10 on the front and rear sides. An elastic band 12 is fixedly connected in each clearance hole. The protective tube 10 passes through it and fits tightly with the elastic band 12. The elastic band 12 has good elasticity and sealing performance, and can automatically fit against the outer wall of the protective tube 10 during its movement, which not only ensures the sealing and protection effect, but also does not affect the normal operation of the traction system.
