Description

Technical Field

[0001] This invention relates to sand barrier laying technology, specifically to a mechanized laying device and method based on willow sand barriers. Background Technology

[0002] Willow sand barriers are a type of sand barrier system that uses willow branches as the core material and forms a grid-like, strip-like, or composite structure through cuttings or weaving. They are widely used in scenarios such as the control of shifting sand dunes, the repair of wind erosion pits, and the protection of plateau wetlands. The core principle is to use willow branches to increase the surface roughness, significantly reduce wind speed, and reduce wind erosion and sand accumulation. At the same time, the sand barrier provides a stable foothold for plant seeds, improves the microclimate and soil conditions, and promotes the natural recovery of vegetation. As a native vegetation of sandy areas, willow has the characteristics of being cold-resistant, heat-resistant, and sand-burial-resistant. Its branches are easy to propagate and grow quickly, and are highly compatible with the sandy ecology, effectively controlling wind and sand movement. It is an important means of controlling desertified land.

[0003] Chinese patent CN217231765U discloses a grass checkerboard sand barrier laying device. Both the grass pressing wheel and the ditching wheel can be adjusted up and down to provide shock absorption and cushioning. The grass pressing wheel and the ditching wheel are connected by a multi-link structure, which can achieve folding and storage. In the preferred embodiment, a sand gathering device is provided to further consolidate the laid grass checkerboard and improve stability. In the preferred embodiment, a feeding chamber that can automatically replenish grass rolls is also provided to ensure the continuity of grass checkerboard laying.

[0004] When using existing laying devices, they can usually only complete the planting of willow branches or the laying of a single material. This makes the windbreak and sand fixation effect dependent on the characteristics of a single material. This dependence makes the sand barriers susceptible to wind erosion, sand burial, or material aging, thereby reducing the survival rate. Summary of the Invention

[0005] The purpose of this invention is to provide a mechanized laying device and method based on willow sand barriers, so as to solve the problems of limited functionality and poor durability of existing laying devices.

The two guide rollers are installed between the inner walls on both sides of the reinforcing frame through bearings.

[0010] Furthermore, a controller is installed in the middle of the outer wall of the battery, a tracked chassis is installed in the middle of the bottom end of the base, and a telescopic drive assembly is installed on the other side of the top of the base. The output end of the telescopic drive assembly passes through the top of the base and is equipped with a trencher.

[0011] Furthermore, the bonding mechanism includes a storage tank, a feed pipe, a pump, a delivery pipe, and a binder nozzle. The storage tank is installed at the top of the base, the feed pipe is installed on one side of the top of the storage tank, the pump is installed on one side of the bottom of the storage tank, two delivery pipes are provided, and the two delivery pipes are respectively installed on the outer walls of the two sides of the pump, and multiple binder nozzles are provided, and the multiple binder nozzles are respectively installed on the lower side of the opposite surfaces of the two delivery pipes.

[0012] Furthermore, the bonding mechanism also includes an adjusting frame, an adjusting drive assembly, and a covering wheel. The adjusting frame is installed between one end of the two conveying pipes. There are two adjusting drive assemblies and two covering wheels. The two adjusting drive assemblies are installed on the top of the adjusting frame, and the top of the two adjusting drive assemblies is installed on the bottom of the base. The two covering wheels are respectively installed on the lower part of the inner wall on both sides of the adjusting frame through bearings.

[0013] Furthermore, the power generation mechanism includes a support column, a support frame, a photovoltaic panel, a wind turbine, and wind direction and speed sensors. The support column is installed on the top of the battery. There are two support frames and two photovoltaic panels. The two support frames are respectively installed on the lower part of the outer wall on both sides of the support column. The two photovoltaic panels are respectively installed on the top of the two support frames. The wind turbine is installed on the top of the support column, and the wind direction and speed sensors are installed on the top of the wind turbine.

[0014] Furthermore, the controller is electrically connected to the bonding mechanism, laying mechanism, storage battery, power generation mechanism, tracked chassis and telescopic drive assembly, the reinforcement frame is set as a triangular frame, the mesh body is woven from biodegradable plant fibers, and the curtain-shaped yellow willow bundle is a yellow willow curtain woven from multiple yellow willow branches.

[0015] Furthermore, the covering wheel is configured as a frustum structure, the binder nozzle is configured as an inclined structure, the delivery pipe is configured as a T-shaped structure, and the upper part of the outer wall of the delivery pipe is configured as a folded pipe.

[0016] Furthermore, the support frame is configured as a triangular structure, and the top surface of the support frame is configured as an inclined surface, so that the wind turbine generator does not contact the photovoltaic power generation panel and the wind direction and speed sensor.

[0017] A method for a mechanized laying device based on willow sand barriers includes the following steps:

[0018] Step 1, Laying Preparation: Transport the device to the target area where the willow sand barrier is to be laid, then check the battery power. If the power is insufficient, use the generator to charge it. The generator uses photovoltaic panels to convert solar energy into electrical energy under sunlight conditions, and at the same time, the wind turbine converts wind energy into electrical energy when there is wind. Both work together to replenish the battery power. Check the amount of adhesive in the storage box. If it is insufficient, add an appropriate amount of adhesive through the feed pipe. Confirm that the willow bundles and the mesh body are installed correctly and in sufficient quantity.

[0019] Step 2, Place the yellow willow: Start the telescopic drive assembly, and its output end drives the trencher to move downwards, opening a trench in the sand that meets the paving requirements. At the same time, start the tracked chassis, allowing the device to move slowly along the pre-planned route. As the device moves forward, the curtain-shaped yellow willow bundles on the storage tray gradually unfold under the action of gravity or slight external force, and fall into the opened trench through the guide chute and the guide plate.

[0020] Step 3: Spraying the binder: Start the pump to deliver the binder in the storage tank to the binder nozzle through the delivery pipe. This allows the binder to be sprayed evenly on the trench and the surrounding sand surface, providing a bonding foundation for subsequent operations. The device continues to move forward, and the covering wheels installed on the lower inner walls of both sides of the adjusting frame cover the surrounding sand on the area where the binder has been sprayed, so that the binder and sand are initially mixed to form a sand layer with a certain degree of adhesion.

[0021] Step 4: Laying the mesh: As the device continues to move forward, the mesh body on the mesh roll is smoothly unfolded under the guidance of the guide roller, so that the mesh body covers the surface of the laid yellow willow sand barrier. At this time, the moving drive component drives the moving frame to move downward, so that the pressure roller applies pressure to the mesh body during the movement, inserting it into the sand.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] (1) This invention achieves efficient mechanized laying of willow sand barriers through the coordinated work of the material guide plate, the material guide trough, the material storage tray, the curtain-shaped willow bundles and the laying mechanism. The curtain-shaped willow bundles on the material storage tray gradually unfold under the action of gravity or slight external force during the device's forward movement, and fall precisely into the pre-opened trench through the material guide trough and the material guide plate. Subsequently, the mesh roll is smoothly unfolded under the guidance of the guide roller, covering the surface of the laid willow sand barrier, and the mesh is firmly inserted into the sand on both sides by the pressing wheel to form a double protective barrier, thereby enhancing the windproof and sand-fixing effect of the sand barrier.

[0024] (2) The present invention significantly enhances the stability of sand barrier foundation by working together with components such as storage tank, feed pipe, pump, delivery pipe and binder nozzle. The bio-based binder is delivered to multiple binder nozzles by the pump and sprayed evenly on the trench and the surrounding sand surface. Then, the covering wheel covers the surrounding sand in the sprayed area, so that the binder and sand are initially mixed to form a sand layer with strong cohesion. The chemical bonding enhances the cohesion between sand particles and effectively improves the shear strength of the foundation.

[0025] (3) The present invention achieves green energy self-sufficiency through the coordinated work of support columns, support frames, photovoltaic power generation panels, wind turbines and wind direction and speed sensors. The photovoltaic power generation panels can efficiently capture solar energy and convert it into electrical energy, and the wind turbines generate electricity synchronously under the drive of wind. Photovoltaic power generation and wind power generation complement each other and charge the storage battery together, thereby ensuring that the device can continue to operate without external power and reducing operating costs.

[0038] As attached Figure 1 To be continued Figure 8 As shown:

[0039] Example 1:

[0040] The present invention provides a mechanized laying device based on willow sand barriers, including a base 1;

[0041] A bonding mechanism 2 is installed on one side of the top of the base 1. A laying mechanism 3 is installed on the top of the bonding mechanism 2. A storage battery 4 is installed in the middle of the top of the base 1. The storage battery 4 provides power support for the various components of the device. A power generation mechanism 5 is installed in the middle of the top of the storage battery 4. The power generation mechanism 5 is used to generate electricity and charge the storage battery 4. A material guide plate 7 is installed in the middle of one end of the storage battery 4. Its function is to guide the unfolded curtain-shaped yellow willow bundles 10 smoothly into the subsequent processing stage. A material guide groove 8 is opened in the middle of the other side of the top of the base 1. Two storage trays 9 are installed on the other side of the top of the base 1. The storage trays 9 are installed on the base 1 through bearings, which can drive the curtain-shaped yellow willow bundles 10 on them to rotate. The outer surfaces of the two storage trays 9 are fitted with curtain-shaped yellow willow bundles 10.

[0042] The laying mechanism 3 includes a fixed frame 31, a mesh roll 32, a reinforcing frame 33, a moving drive assembly 34, a moving frame 35, and a pressure roller 36. The fixed frame 31 is installed at the top of the bonding mechanism 2. The mesh roll 32 is installed between the inner walls of both sides of the fixed frame 31. The reinforcing frame 33 is installed on the lower side of one end of the fixed frame 31. There are two moving drive assemblies 34 and two pressure rollers 36. The two moving drive assemblies 34 are embedded in one end of the reinforcing frame 33. The moving drive assembly 34 adopts an electric telescopic rod or a cylinder, etc., which can drive the moving frame 35 to move up and down. The moving frame 35 is installed between the bottom ends of the two moving drive assemblies 34. The two pressure rollers 36 are installed on the lower side of the inner wall of the moving frame 35 through bearings.

[0043] The laying mechanism 3 also includes a placement groove 37, a mesh body 38, and a guide roller 39. There are two placement grooves 37 and two guide rollers 39. The two placement grooves 37 are respectively opened on the top two sides of the fixed frame 31. The mesh body 38 is wound and installed on the outer surface of the mesh roll 32. The two guide rollers 39 are installed between the inner walls of the two sides of the reinforcing frame 33 through bearings.

[0044] A controller 6 is installed in the middle of the outer wall of the battery 4. A tracked chassis 11 is installed in the middle of the bottom end of the base 1. The tracked chassis 11 has good off-road performance and adaptability and can travel stably on complex terrains such as deserts. A telescopic drive assembly 12 is installed on the other side of the top of the base 1. The telescopic drive assembly 12 adopts an electric telescopic rod or cylinder, which can drive the trencher 13 to move up and down to realize the trenching function. The output end of the telescopic drive assembly 12 passes through the top of the base 1 and is equipped with the trencher 13.

[0045] The controller 6 is electrically connected to the bonding mechanism 2, the laying mechanism 3, the battery 4, the power generation mechanism 5, the tracked chassis 11, and the telescopic drive assembly 12. It is used to control the coordinated operation of all components of the entire device. The reinforcing frame 33 is set as a triangular frame. This structure has high stability and can enhance the strength of the entire laying mechanism 3. The mesh body 38 is woven from biodegradable plant fibers. This material can not only play a role in fixing the yellow willow sand barrier to a certain extent, but also will not cause long-term pollution to the environment. The curtain-shaped yellow willow bundle 10 is a yellow willow curtain woven from multiple yellow willow branches. It is the main material for constructing the yellow willow sand barrier.

[0046] Working principle: First, the curtain-shaped bundles of yellow willow 10 are placed on the storage tray 9. The tracked chassis 11 drives the entire device to a suitable position. During the movement of the device, the telescopic drive component 12, under the control of the controller 6, has its output end penetrating through the top of the base 1 and driving the trench opener 13 to perform trenching operations. At the same time, the curtain-shaped bundles of yellow willow 10 on the storage tray 9 gradually unfold under the action of gravity or slight external force as the device moves forward, and fall precisely into the pre-drilled trench through the guide chute 8 and the guide plate 7, forming a yellow willow sand barrier. Subsequently, the adhesive bonding mechanism 2 sprays glue and covers the soil. Finally, the device continues to move forward, and the mesh body 38 on the mesh roll 32 unfolds smoothly under the guidance of the guide roller 39, so that the mesh body 38 covers the surface of the laid yellow willow sand barrier. During this process, the moving drive component 34 drives the moving frame 35 downward, causing the pressure roller 36 to apply pressure to the mesh body 38, inserting both sides of the mesh body 38 into the sand, enhancing the stability of the sand barrier. The mesh, together with the laid willow, forms a double protective barrier, thereby enhancing the windbreak and sand-fixing effect of the sand barrier. Compared with the traditional single-material laying method, this willow sand barrier improves windbreak efficiency. At the same time, the mesh body 38 can degrade into organic matter, promoting the reproduction of microorganisms and building a stable ecosystem together with the willow, greatly improving the durability and ecological restoration capacity of the sand barrier. This makes the sand barrier less susceptible to wind erosion, sand burial, or material aging, increasing the survival rate, and thus realizing the mechanization and automation of willow sand barrier laying, improving laying efficiency and quality.

[0047] Example 2:

[0048] This embodiment is basically the same as the previous embodiment, except that the bonding mechanism 2 includes a storage tank 21, a feed pipe 22, a pump 23, a conveying pipe 24, and a binder nozzle 25. The storage tank 21 is installed on the top of the base 1. The storage tank 21 is made of high-strength plastic material, which has good corrosion resistance and sealing performance, and can safely store the binder. The feed pipe 22 is installed on one side of the top of the storage tank 21, which facilitates the addition of binder into the tank. The pump 23 is installed on one side of the bottom of the storage tank 21. The pump 23 is an electric pump that can draw the binder from the storage tank 21 and generate a certain pressure to provide power for the conveying of the binder. There are two conveying pipes 24, and the two conveying pipes 24 are respectively installed on the outer walls of the two sides of the pump 23. There are multiple binder nozzles 25, and the multiple binder nozzles 25 are respectively installed on the lower side of the opposite surface of the two conveying pipes 24.

[0049] The bonding mechanism 2 also includes an adjusting frame 26, an adjusting drive assembly 27, and a covering wheel 28. The adjusting frame 26 is installed between one end of the two conveying pipes 24. There are two adjusting drive assemblies 27 and two covering wheels 28. The two adjusting drive assemblies 27 are installed on the top of the adjusting frame 26. The adjusting drive assembly 27 adopts an electric telescopic rod or a cylinder, etc. The adjusting drive assembly 27 can control the up and down movement of the adjusting frame 26. The tops of the two adjusting drive assemblies 27 are installed on the bottom of the base 1. The two covering wheels 28 are installed on the lower part of the inner wall on both sides of the adjusting frame 26 through bearings.

[0050] The covering wheel 28 is designed as a frustum structure, which can better gather the soil towards the center during rolling to achieve the covering function. The binder nozzle 25 is designed as an inclined structure, which allows the binder to be sprayed at a certain angle, expanding the coverage area of ​​the binder and improving the binding effect. The delivery pipe 24 is designed as a T-shaped structure, and the upper part of the outer wall of the delivery pipe 24 is designed as a folded pipe. The folded pipe design allows the delivery pipe 24 to have a certain amount of expansion and contraction space when the adjusting frame 26 moves up and down, avoiding damage to the pipe due to adjustment.

[0051] Working principle: First, the binder is added to the storage tank 21 through the feed pipe 22. When the device moves to the position where the binder needs to be sprayed, the pump 23 starts working, drawing the binder from the storage tank 21 and conveying it through the delivery pipe 24 to multiple inclined binder nozzles 25. The binder nozzles 25 evenly spray the binder onto the sandy trench and the surrounding sand surface, providing a bonding base for subsequent operations. At the same time, the adjustment drive component 27 starts working, adjusting the height of the adjustment frame 26 according to actual needs, thereby driving the covering wheel 28 to... In the soil covering operation, the soil covering wheel 28 covers the surrounding sand over the area where the binder has been sprayed, and covers the curtain-shaped bundles of yellow willow 10 laid in the trench with soil. This allows the binder to mix with the sand initially, forming a sand layer with a certain degree of cohesion, which enhances the stability of the yellow willow sand barrier. This process enhances the cohesion between sand particles through chemical bonding, effectively improving the shear strength of the foundation, reducing wind erosion and sand accumulation, and providing a solid guarantee for the long-term stability of the sand barrier. The entire binding mechanism 2 effectively improves the shear strength and durability of the sand barrier by precisely controlling the spraying of the binder and the soil covering operation.

[0052] Example 3:

[0053] This embodiment is basically the same as the previous embodiment, except that the power generation mechanism 5 includes a support column 51, a support frame 52, a photovoltaic power generation panel 53, a wind turbine 54, and a wind direction and speed sensor 55. The support column 51 is installed on the top of the battery 4. The support column 51 is made of high-strength, corrosion-resistant alloy material, which can withstand the strong winds and sandstorms in the desert area, and has good stability. There are two support frames 52 and two photovoltaic power generation panels 53. The two support frames 52 are installed on the lower part of the outer wall on both sides of the support column 51, and the two photovoltaic power generation panels 53 are installed on the top of the two support frames 52. The wind turbine 54 is installed on the top of the support column 51. The wind turbine 54 adopts a small and efficient design, which can generate electricity stably under the variable wind speed conditions in the desert area. Its blades are treated with a special anti-sand coating to reduce the wear of sand and dust on the blades and extend their service life. The wind direction and speed sensor 55 is installed on the top of the wind turbine 54. The wind direction and speed sensor 55 can monitor the wind direction and wind speed information in the desert area in real time and transmit these data to the controller 6.

[0054] The support frame 52 is designed with a triangular structure, which has extremely high stability and can effectively resist strong winds in desert areas, preventing the photovoltaic panel 53 from swaying or being damaged in sandstorms. The top surface of the support frame 52 is designed with an inclined surface, which is optimized according to the sunlight angle in desert areas, so that the photovoltaic panel 53 can receive solar radiation to the maximum extent and improve the conversion efficiency of solar energy. The wind turbine 54 does not come into contact with the photovoltaic panel 53 and the wind direction and speed sensor 55, avoiding mutual interference between the components and ensuring that they can work independently.

[0055] Working Principle: First, the device is transported to a remote target area with abundant solar and wind energy resources, such as deserts or Gobi. At this time, the photovoltaic panel 53 starts working. Under sunlight, the photovoltaic panel 53 converts solar energy into electrical energy. Simultaneously, the device will generate wind during operation. The wind turbine 54 will rotate with the help of the wind, converting wind energy into electrical energy. The wind direction and speed sensor 55 monitors the wind direction and speed in real time and transmits the data to the controller 6. The controller 6 adjusts the operating status of the wind turbine 54 according to the data to ensure its efficient power generation. The electrical energy generated by the photovoltaic panel 53 and the wind turbine 54 together replenishes the battery 4, which in turn provides power to the entire device, ensuring the normal operation of the device and realizing the mechanized laying of the Huangliu sand barrier. The entire power generation mechanism 5 generates electricity through the complementary use of multiple energy sources, which not only reduces carbon emissions and achieves energy self-sufficiency, but also reduces operating costs through the use of renewable energy, demonstrating the dual advantages of environmental protection and economic benefits. This solves the problem of power supply difficulties in remote areas and improves the reliability and energy utilization efficiency of the device.

[0056] Example 4:

[0057] A method for a mechanized laying device based on willow sand barriers includes the following steps:

[0058] Step 1, Laying Preparation: Transport the device to the target area where the yellow willow sand barrier is to be laid, and then check the power of the storage battery 4. If the power is insufficient, use the power generation mechanism 5 to charge it. The power generation mechanism 5 uses the photovoltaic power generation panel 53 to convert solar energy into electrical energy under sunlight conditions. At the same time, the wind turbine 54 converts wind energy into electrical energy when there is wind. The two together replenish the power of the storage battery 4. Check the remaining amount of adhesive in the storage box 21. If it is insufficient, add an appropriate amount of adhesive through the feed pipe 22, and confirm that the curtain-shaped yellow willow bundles 10 and the mesh body 38 are installed correctly and in sufficient quantity.

[0059] Step 2, Place the yellow willow: Start the telescopic drive assembly 12, and its output end drives the trencher 13 to move downward, opening a trench in the sand that meets the paving requirements. At the same time, start the tracked chassis 11, allowing the device to move slowly along the pre-planned route. As the device moves forward, the curtain-shaped yellow willow bundles 10 on the storage tray 9 gradually unfold under the action of gravity or slight external force, and fall into the opened trench through the guide chute 8 and the guide plate 7.

[0060] Step 3, spraying binder: Start the pump 23 to deliver the binder in the storage tank 21 to the binder nozzle 25 through the delivery pipe 24. This allows the binder to be sprayed evenly on the trench and the surrounding sand surface, providing a bonding foundation for subsequent operations. The device continues to move forward, and the covering wheels 28 installed on the lower part of the inner walls on both sides of the adjusting frame 26 cover the surrounding sand on the area where the binder has been sprayed, so that the binder and sand are initially mixed to form a sand layer with a certain degree of adhesion.

[0061] Step 4: Laying the mesh: As the device continues to move forward, the mesh body 38 on the mesh roll 32 is smoothly unfolded under the guidance of the guide roller 39, so that the mesh body 38 covers the surface of the laid yellow willow sand barrier. At this time, the moving drive component 34 drives the moving frame 35 to move downward, so that the pressure roller 36 applies pressure to the mesh body 38 during the movement, inserting it into the sand, enhancing the stability of the sand barrier, and making the mesh and the laid yellow willow form a double protective barrier, strengthening the windproof and sand-fixing effect.

[0062] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

8. A method for a mechanized laying device based on willow sand barriers, applicable to the mechanized laying device based on willow sand barriers as described in any one of claims 1 to 7, characterized in that, Includes the following steps: Step 1, Laying Preparation: Transport the device to the target area where the yellow willow sand barrier is to be laid, and then check the power of the storage battery (4). If the power is insufficient, use the power generation mechanism (5) to charge it. The power generation mechanism (5) uses the photovoltaic power generation panel (53) to convert solar energy into electrical energy under sunlight conditions. At the same time, the wind turbine (54) converts wind energy into electrical energy when there is wind. The two together replenish the power of the storage battery (4). Check the remaining amount of adhesive in the storage box (21). If it is insufficient, add an appropriate amount of adhesive through the feed pipe (22). Confirm that the curtain-shaped yellow willow bundles (10) and the mesh body (38) are installed correctly and in sufficient quantity. Step 2, Place the yellow willow: Start the telescopic drive assembly (12), and its output end drives the trench opener (13) to move downwards, opening a trench in the sand that meets the paving requirements. At the same time, start the tracked chassis (11) and let the device move slowly along the pre-planned route. As the device moves forward, the curtain-shaped yellow willow bundles (10) on the storage tray (9) gradually unfold under the action of gravity or slight external force, and fall into the opened trench through the guide chute (8) and the guide plate (7). Step 3, spraying binder: Start the pump (23) to deliver the binder in the storage tank (21) to the binder nozzle (25) through the delivery pipe (24). This will allow the binder to be sprayed evenly on the trench and the surrounding sand surface, providing a bonding foundation for subsequent operations. The device continues to move forward, and the covering wheel (28) installed on the lower part of the inner wall on both sides of the adjusting frame (26) covers the surrounding sand in the area where the binder has been sprayed, so that the binder and sand are initially mixed to form a sand layer with a certain degree of adhesion. Step 4, Laying the mesh: As the device continues to move forward, the mesh body (38) on the mesh roll (32) unfolds smoothly under the guidance of the guide roller (39), so that the mesh body (38) covers the surface of the laid yellow willow sand barrier. At this time, the moving drive component (34) drives the moving frame (35) to move downward, so that the pressure roller (36) applies pressure to the mesh body (38) during the movement, inserting it into the sand.
