Description

Technical Field

[0001] This invention relates to the field of hydroseeding, specifically a hydroseeding device for planting grass and protecting slopes along city walls and its operating method. Background Technology

[0002] With the rapid development of urban modernization, people are becoming more and more aware of the protection of ancient buildings. Among them, the ancient city walls are being restored to their original appearance with the aim of restoring them to their original state. The principle of "restoring the old as before" is followed, and the technology of reversibility and reprocessability in the restoration process is applied. The outer city wall is built according to the trend and preservation condition of the rammed earth wall.

[0003] The specific restoration method is as follows: the inner city wall is backed with machine-made bricks and supported by a structure. Grass is planted to protect the exposed loess slopes on the inner side of the city wall. Hydroseeding technology is used, in which water is used as a carrier to fully mix the treated mixture with water to form a mixture. The mixture includes grass seeds, tree seeds, flower seeds, seed stems, nutrients, adhesives, water-retaining agents, fertilizers, fiber covering materials, and soil conditioners. The mixture is then evenly sprayed onto the soil surface of the greening area using a hydroseeding device.

[0004] The spraying equipment is generally a spraying device loaded onto a mobile vehicle. It moves with the vehicle. The vehicle is large and heavy. When spraying the mixture on the slope of the city wall, the vehicle needs to be driven to the side of the slope. The weight of the vehicle will crush and damage the ground around the slope. At the same time, the large size of the vehicle makes it difficult to adjust the direction. The extended spraying pipe may touch the city wall, causing damage to the ancient buildings. In some cases, in order to provide enough space for the vehicle to move, it is necessary to remove some vegetation.

[0005] Therefore, in response to the above problems, a hydroseeding greening device for planting grass on the slopes of city walls and its operation method are proposed. Summary of the Invention

The inner ring of the ring is sealed and rotatably connected to the rod body. The inside of the ring is connected to the liquid inlet holes, and the ring is connected to the external pump body through a hose. Two drive wheels are symmetrically arranged at each end of the rectangular frame, and the axis of the drive wheels is perpendicular to the end surface of the rectangular frame. Each rod is equipped with a gear, and a rack that meshes with the gear is installed on the inner wall of the through hole.

[0009] Preferably, two electric actuators are symmetrically arranged at both ends of the rectangular frame, with the output end of the electric actuator facing upward. The output end of the electric actuator is provided with an L-shaped plate, the horizontal part of the L-shaped plate is fixedly connected to the output end of the electric actuator, and the vertical part of the L-shaped plate is installed with the drive wheel.

[0010] Preferably, the surface of the cylinder is provided with multiple spray holes, each spray hole being arranged on one side of the sliding hole; Each cannula is U-shaped, with one end of the cannula slidably connected to the sliding hole and the other end of the cannula slidably connected to the spray hole.

[0011] Preferably, each drive block has an end plate fixedly connected to its outer end face, and a water spray pipe is provided on the end plate. The water spray pipe extends outward from the rectangular frame, and multiple water spray holes are opened on the water spray pipe. The water spray holes are arranged with the drainage direction facing downward, and the water spray pipe is connected to an external water pump through a water supply pipe.

[0012] Preferably, each end plate is provided with a T-shaped groove, and the end of each water spray pipe is provided with a slider that fits the groove.

[0013] Preferably, a horizontal plate is fixedly connected between the hose and the water supply pipe, and the two ends of the horizontal plate are slidably connected to the upper surface of the rectangular frame.

[0014] Preferably, the pressure plate is threaded onto the insertion tube.

[0015] An operating method for a hydroseeding greening device for planting grass and protecting slopes of city walls, the operating method using the aforementioned hydroseeding greening device for planting grass and protecting slopes of city walls, includes the following steps: Step 1: Slope Cleaning and Treatment Remove debris, weeds, gravel, and loose soil from the slope to ensure a smooth surface; The slope was repaired as necessary, and damaged areas were treated to make it suitable for hydroseeding. Step 2: Prepare the hydroseeding substrate Prepare a hydroseeding substrate based on the specific conditions of the slope, including vegetative soil, plant fiber, water-retaining agent, adhesive, nutrient substrate, soil conditioner, microbial agent, organic fertilizer and seeds; Step 3: Hydroseeding Move the hydroseeding device to the slope of the city wall, adjust the position between the hydroseeding device and the slope of the city wall, and then operate the hydroseeding device to spray the prepared substrate and seed mixture evenly onto the slope.

[0018] 2. In this invention, the cylinder moves linearly and rotates simultaneously. The linear movement of the cylinder evenly sprays the mixture onto the slope of the city wall, while the rotation of the cylinder further dissolves any undissolved granular fertilizer particles in the mixture, thus agitating the mixture and ensuring that the seeds sprayed on the slope of the city wall receive uniform nutrition.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Reference Figure 1 - Figure 7 A hydroseeding greening device for planting grass and protecting slopes of city walls includes a rectangular frame 1. Both sides of the rectangular frame 1 have strip-shaped through holes, which are set along the length of the rectangular frame 1. A screw rod 2 is rotatably connected to each of the two through holes. A drive block 3 is threadedly connected to each of the two screw rods 2. A rod body 4 is rotatably connected to the drive block 3. A cylinder 5 is fixedly connected between the two rod bodies 4. Multiple sliding holes 6 are opened on the surface of the cylinder 5. The rod body 4 is hollow inside. Multiple liquid inlet holes 7 are opened on the outer ring of the rod body 4. A hollow ring 8 is provided on the outer ring of the rod body 4. The inner ring of the ring 8 is sealed and rotatably connected to the rod body 4. The inside of the ring 8 is connected to the liquid inlet holes 7. The ring 8 is connected to the external pump body through a hose 9. Two drive wheels 10 are symmetrically provided at both ends of the rectangular frame 1, and the axis of the drive wheels 10 is perpendicular to the end surface of the rectangular frame 1. Each rod 4 is equipped with a gear 11, and a rack 12 that meshes with the gear 11 is provided on the inner side wall of the through hole; This embodiment presents a hydroseeding device for planting grass and protecting slopes along city walls. This device is suitable for hydroseeding city wall slopes in areas with limited space. The device can be loaded onto a vehicle and transported to one side of the city wall slope. The vehicle is parked away from the slope, and the device is then removed from the vehicle and placed horizontally on the ground. Figure 6As shown, the hydroseeding device moves from the vehicle position towards the slope of the city wall. Drive wheel 10, driven by a hub motor, rotates, pulling the rectangular frame 1 onto the slope of the city wall. The rectangular frame 1 is then adjusted to rotate counter-clockwise until it reaches a position similar to... Figure 6 As shown in the diagram, then operate the hydroseeding device to mix and spray the materials. The specific process of spraying the mixed material using the hydroseeding greening device is as follows: the mixed material is injected into the hose 9 through the pump body on the vehicle, and then injected into the ring body 8 through the hose 9. After that, it flows into the cylinder 5 through the liquid inlet 7 on the rod body 4. The mixed material is injected into the cylinder 5 and sprayed out from the sliding hole 6 on the cylinder 5. The lead screw 2 is driven by a motor that rotates in both directions. The lead screw 2 drives the cylinder 5 to move through the drive block 3. The cylinder 5 moves along the length of the rectangular frame 1. At the same time as the cylinder 5 moves, the gear 11 meshes with the rack 12 and drives the cylinder 5 to rotate. At this time, the cylinder 5 moves in a straight line and rotates. The straight movement of the cylinder 5 sprays the mixed material evenly on the slope of the city wall. The rotation of the cylinder 5 can further dissolve the granular fertilizer in the mixed material that has not dissolved in time, and play a role in stirring the mixed material, so that the seeds sprayed on the slope of the city wall receive uniform nutrition, and the subsequent seed growth tends to be the same.

[0023] Reference Figure 1 - Figure 7 Each sliding hole 6 is slidably connected with an insertion tube 13. The inner end of the insertion tube 13 is connected to the inside of the cylinder 5 by a spring 14. A hole 26 is opened on the insertion tube 13, and a pressure plate 15 is provided on the outer wall of the outer end of the insertion tube 13. The insertion tube 13 is slidably connected to the sliding hole 6 by the spring 14. Relying on the elastic force of the spring 14, the insertion tube 13 can be inserted into the ground and inject the mixture below the soil layer so that the soil covers the seeds. After the seeds take root and grow, the roots can effectively hold the soil and stabilize the slope of the city wall. At the same time, the vegetation on the surface of the soil layer can reduce the erosion of the slope of the city wall by rainwater. The specific working process of the insertion tube 13 is as follows: when the insertion tube 13 touches the soil layer, the pressure plate 15 presses against the soil surface, while the tip of the insertion tube 13 will be inserted below the ground. The mixture is injected into the insertion tube 13 through the hydraulic pressure of the mixing inside the cylinder 5, and finally sprayed out from the insertion tube 13 and injected into the soil layer to stabilize the seeds inside the soil layer and stably store the seeds and nutrient solution.

[0024] Reference Figure 1 - Figure 2 Two electric actuators 16 are symmetrically arranged at both ends of the rectangular frame 1. The output end of the electric actuator 16 faces upward. An L-shaped plate 17 is provided at the output end of the electric actuator 16. The horizontal part of the L-shaped plate 17 is fixedly connected to the output end of the electric actuator 16, and the vertical part of the L-shaped plate 17 is installed with the drive wheel 10. Considering the passability of the spraying greening device, the height of the rectangular frame 1 from the ground is controlled by the electric actuator 16, so that the spraying greening device can pass through some higher road embankments. At the same time, the gap between the cylinder 5 and the soil layer on the surface of the city wall slope can be adjusted so that the pressure plate 15 can be effectively squeezed on the soil surface and the tip of the insertion tube 13 can also be effectively inserted into the soil layer, which is suitable for situations with different soil hardness.

[0025] Reference Figure 1 - Figure 9 The surface of the cylinder 5 is provided with multiple spray holes 18, and each spray hole 18 is provided on one side of the sliding hole 6. Each cannula 13 is arranged in a U-shape. One end of the cannula 13 is slidably connected to the sliding hole 6, and the other end of the cannula 13 is slidably connected to the spray hole 18. A second hole 19 is opened at the end of the cannula 13 that is slidably connected to the spray hole 18. In this embodiment, the insertion tube 13 is U-shaped. One end of the insertion tube 13 is inserted into the sliding hole 6, and the other end is inserted into the spray hole 18. The connection between the insertion tube 13 and the spring 14 is sealed. When the pressure plate 15 on the insertion tube 13 is not pressed against the soil surface, the second hole 19 on the other end of the insertion tube 13 is connected to the inside of the cylinder 5. The mixture enters the other end of the insertion tube 13 from the second hole 19, and then the mixture is sprayed out from the spray hole 18 and sprayed onto the soil surface. When the pressure plate 15 on the insertion tube 13 is pressed against the soil surface, the insertion tube 13 moves as a whole towards the axis of the cylinder 5. The second hole 19 on the insertion tube 13 is sealed, and at the same time, the first hole 26 on the insertion tube 13 is connected to the inside of the cylinder 5. At this time, the mixture enters the first end of the insertion tube 13 from the first hole 26, and then the mixture is sprayed out from the first end of the insertion tube 13 and injected into the soil. The insertion tube 13 can both spray the mixed material onto the soil surface and inject it into the soil layer. This allows for spraying the mixed material both inside and outside the soil layer of the city wall slope. After the seeds in the mixed material take root, the roots inside and outside the soil layer intertwine and further grasp the soil, locking in more soil and improving the adhesion of the vegetation. This further enhances the resistance of the city wall slope to rainwater erosion.

[0026] Reference Figure 1 - Figure 11 Each drive block 3 has an end plate 20 fixedly connected to its outer end face. The end plate 20 is provided with a water spray pipe 21. The water spray pipe 21 extends outward from the rectangular frame 1. Multiple water spray holes are opened on the water spray pipe 21. The water spray holes are set to drain downward. The water spray pipe 21 is connected to an external water pump through a water supply pipe 22. The water spray pipe 21 installed on the end plate 20 is used to wet the surface of the city wall slope or to irrigate the soil layer of the city wall slope. Water spray pipes 21 are installed on both sides of the rectangular frame 1. When the rectangular frame 1 moves from left to right, the water spray pipe 21 on the right side sprays water to irrigate the surface of the soil layer on the slope of the city wall. When the rectangular frame 1 moves to the soil irrigation area by the drive wheel 10, it sprays and mixes the soil in the area, softening the soil and facilitating the insertion of the insertion pipe 13. At the same time, the water spray pipe 21 on the right side of the rectangular frame 1 will irrigate the area that has already been sprayed and mixed with water for a second time, achieving further irrigation and ensuring that the seeds have a sufficient supply of water. As for the amount of water sprayed, it is controlled by a water pump. During irrigation, the amount of water sprayed is reduced to prevent the mixed materials from being washed away.

[0027] Reference Figure 1 - Figure 11 Each end plate 20 is provided with a T-shaped groove 23, and each water spray pipe 21 is provided with a slider 24 that fits the groove 23 at its end. The water spray pipe 21 is detachably installed in the groove 23 on the end plate 20, so that the spraying greening device can pass through some narrow areas, so as not to obstruct the movement of the spraying greening device. When the spraying greening device is transported to the vehicle, the water spray pipe 21 is detached in advance to facilitate the transportation and placement of the spraying greening device.

[0028] Reference Figure 1 - Figure 12 A horizontal plate 25 is fixedly connected between the hose 9 and the water supply pipe 22, and the two ends of the horizontal plate 25 are slidably connected to the upper surface of the rectangular frame 1. The hose 9 and water supply pipe 22 are mounted on the rectangular frame 1 via the horizontal plate 25 to prevent them from sliding on the soil surface and disturbing the already sprayed mixture, thus interfering with the uniformity of the spraying. At the same time, the hose 9 and water supply pipe 22 are connected to the rectangular frame 1 as a whole. When the spraying greening device moves, the hose 9 and water supply pipe 22 also move with the spraying greening device, reducing the damage rate at the connection between the hose 9 and the ring body 8 and the connection between the water supply pipe 22 and the spray pipe 21.

[0029] Reference Figure 1 - Figure 9 The pressure plate 15 is threaded onto the insertion tube 13; The pressure plate 15 is threadedly connected to the insertion tube 13, and the distance between the pressure plate 15 and one end of the insertion tube 13 can be adjusted. When the distance between the pressure plate 15 and one end of the insertion tube 13 is large, the insertion tube 13 can be inserted into a deeper soil layer, which is suitable for softer soil conditions. In conjunction with the electric push rod 16, the flexibility of the spraying greening device is further improved.

[0030] Working principle: The hydroseeding device of this invention can adapt to hydroseeding of city wall slopes in areas with limited space. This device can be loaded onto a vehicle and transported to one side of the city wall slope. The vehicle is parked away from the slope, and the device is then removed from the vehicle and placed horizontally on the ground. Figure 6 As shown, the hydroseeding device moves from the vehicle position towards the slope of the city wall. Drive wheel 10, driven by a hub motor, rotates, pulling the rectangular frame 1 onto the slope of the city wall. The rectangular frame 1 is then adjusted to rotate counter-clockwise until it reaches a position similar to... Figure 6 As shown in the diagram, then operate the hydroseeding device to mix and spray the materials. The specific process of spraying the mixed material in the hydroseeding greening device is as follows: the mixed material is injected into the hose 9 through the pump body on the vehicle, and then injected into the ring body 8 through the hose 9. After that, it flows into the cylinder 5 through the liquid inlet 7 on the rod body 4. The mixed material is injected into the cylinder 5 and sprayed out from the sliding hole 6 on the cylinder 5. The lead screw 2 is driven by a motor that rotates in both directions. The lead screw 2 drives the cylinder 5 to move through the drive block 3. The cylinder 5 moves along the length of the rectangular frame 1. At the same time as the cylinder 5 moves, the gear 11 meshes with the rack 12 and drives the cylinder 5 to rotate. At this time, the cylinder 5 moves in a straight line and rotates. The straight movement of the cylinder 5 sprays the mixed material evenly on the slope of the city wall. The rotation of the cylinder 5 can further dissolve the granular fertilizer in the mixed material that has not dissolved in time, and play a role in stirring the mixed material so that the seeds sprayed on the slope of the city wall receive uniform nutrition. After the subsequent seeds grow in a similar state, The insertion tube 13 is slidably connected to the sliding hole 6 by the spring 14. Relying on the elastic force of the spring 14, the insertion tube 13 can be inserted into the ground and inject the mixture below the soil layer so that the soil covers the seeds. After the seeds take root and grow, the roots can effectively hold the soil and stabilize the slope of the city wall. At the same time, the vegetation on the surface of the soil layer can reduce the erosion of the slope of the city wall by rainwater. The specific working process of the insertion tube 13 is as follows: when the insertion tube 13 touches the soil layer, the pressure plate 15 presses against the soil surface, while the tip of the insertion tube 13 will be inserted below the ground. The mixture is injected into the insertion tube 13 through the hydraulic pressure of the mixing inside the cylinder 5, and finally sprayed out from the insertion tube 13 and injected into the soil layer to stabilize the seeds inside the soil layer and stably store the seeds and nutrient solution. Considering the passability of the spraying greening device, the height of the rectangular frame 1 from the ground is controlled by the electric push rod 16, so that the spraying greening device can pass through some higher road embankments. At the same time, the gap between the cylinder 5 and the soil layer on the surface of the city wall slope can be adjusted so that the pressure plate 15 can be effectively squeezed on the soil surface and the tip of the insertion tube 13 can also be effectively inserted into the soil layer, which is suitable for different soil layers with different hardness. The insertion tube 13 is U-shaped, with one end inserted into the sliding hole 6 and the other end inserted into the spray hole 18. The connection between the insertion tube 13 and the spring 14 is sealed. When the pressure plate 15 on the insertion tube 13 is not pressed against the soil surface, the second hole 19 on the other end of the insertion tube 13 is connected to the inside of the cylinder 5. The mixture enters the other end of the insertion tube 13 through the second hole 19 and then sprays out from the spray hole 18, spraying the mixture onto the soil surface. When the pressure plate 15 on the insertion tube 13 is pressed against the soil surface, the insertion tube 13 moves as a whole towards the axis of the cylinder 5, and the second hole 19 on the insertion tube 13 is sealed. At the same time, the first hole 26 on the insertion tube 13 is connected to the inside of the cylinder 5. At this time, the mixture enters the first end of the insertion tube 13 through the first hole 26 and then sprays out from the first end of the insertion tube 13 and injects into the soil. The insertion tube 13 can spray the mixed material onto the soil surface and inject it into the soil. The mixed material can be sprayed both inside and outside the soil layer of the city wall slope. After the seeds in the mixed material take root, the roots inside and outside the soil layer intertwine and further grasp the soil, locking in more soil and improving the adhesion of vegetation, thereby further improving the resistance of the city wall slope to rain erosion. The water spray pipe 21 installed on the end plate 20 is used to wet the surface of the city wall slope or to irrigate the soil layer of the city wall slope. Water spray pipes 21 are installed on both sides of the rectangular frame 1. When the rectangular frame 1 moves from left to right, the water spray pipe 21 on the right side sprays water to irrigate the surface of the soil layer on the slope of the city wall. When the rectangular frame 1 moves to the soil irrigation area by the drive wheel 10, it sprays and mixes the soil in the area, softening the soil and facilitating the insertion of the insertion pipe 13. At the same time, the water spray pipe 21 on the right side of the rectangular frame 1 will irrigate the area that has already been sprayed and mixed with water for a second time, achieving further irrigation and ensuring that the seeds have a sufficient supply of water. The water spray pipe 21 is detachably installed in the groove 23 on the end plate 20, so that the spraying greening device can pass through some narrow areas, so as not to obstruct the movement of the spraying greening device. When the spraying greening device is transported to the vehicle, the water spray pipe 21 is removed in advance to facilitate the transportation and placement of the spraying greening device. The hose 9 and water supply pipe 22 are mounted on the rectangular frame 1 via the horizontal plate 25 to prevent them from sliding on the soil surface and disturbing the sprayed mixture, thus interfering with the uniformity of the spraying. At the same time, the hose 9 and water supply pipe 22 are connected to the rectangular frame 1 as a whole. When the spraying greening device moves, the hose 9 and water supply pipe 22 also move with the spraying greening device, reducing the damage rate at the connection between the hose 9 and the ring body 8 and the connection between the water supply pipe 22 and the spray pipe 21, because the connection between the hose 9 and the water supply pipe 22 is prone to breakage after repeated swinging. The pressure plate 15 is threadedly connected to the insertion tube 13, and the distance between the pressure plate 15 and one end of the insertion tube 13 can be adjusted. When the distance between the pressure plate 15 and one end of the insertion tube 13 is large, the insertion tube 13 can be inserted into a deeper soil layer, which is suitable for softer soil conditions. In conjunction with the electric push rod 16, the flexibility of the spraying greening device is further improved.

[0031] Reference Figure 13 An operating method for a hydroseeding greening device for planting grass and protecting slopes of city walls, the operating method using the aforementioned hydroseeding greening device for planting grass and protecting slopes of city walls, includes the following steps: Step 1: Slope Cleaning and Treatment Remove debris, weeds, gravel, and loose soil from the slope to ensure a smooth surface; The slope was repaired as necessary, and damaged areas were treated to make it suitable for hydroseeding. Step 2: Prepare the hydroseeding substrate Prepare a hydroseeding substrate based on the specific conditions of the slope, including vegetative soil, plant fiber, water-retaining agent, adhesive, nutrient substrate, soil conditioner, microbial agent, organic fertilizer and seeds; Step 3: Hydroseeding Move the hydroseeding device to the slope of the city wall, adjust the position between the hydroseeding device and the slope of the city wall, and then operate the hydroseeding device to spray the prepared substrate and seed mixture evenly onto the slope.
