Description
Technical Field
[0001] This invention relates to the technical field of desertification control and photovoltaic power station construction, and in particular to a device for sand leveling and sand fixation. Background Technology
[0002] In the fields of desertification control and photovoltaic power station construction, land leveling and sand fixation are two key technical aspects. The traditional operation mode usually adopts a step-by-step construction method of "leveling first and then fixing sand". That is, heavy machinery such as bulldozers and graders are used to level, scrape and roughly level the sand dunes first, and then manual labor or special equipment are used to lay straw grids, sand-fixing nets or spray chemical sand-fixing agents.
[0003] However, existing leveling equipment can only achieve macro-leveling of the terrain, which cannot achieve the high precision leveling required for photovoltaic panel installation. Furthermore, dry sand has extremely low cohesion, poor compaction effect, and serious dust generation. Traditional equipment usually does not have on-site humidification function, or humidification and compaction are separated, resulting in insufficient compaction and easy settling later. Chemical sand-fixing agents usually need to be evenly sprayed on the leveled sand surface and lightly pressed into the surface layer to achieve the best effect. However, in traditional processes, leveling and spraying are done by different equipment. After spraying, there is a lack of timely surface compaction, causing the sand-fixing agent to remain on the surface and be easily blown away by the wind or become ineffective as the sand particles move. Summary of the Invention
[0004] The purpose of this invention is to provide a sand leveling and sand fixation device to alleviate the technical problems existing in the prior art, such as the inability to achieve the flatness required for photovoltaic panels, the easy settling due to poor compaction effect, and the failure of the sand-fixing agent due to its remaining on the surface.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a device for leveling and stabilizing sandy land, comprising a tracked vehicle body, a water supply structure, a liquid supply structure, a roller structure, an auxiliary structure, and a pressure roller structure. The tracked vehicle body includes a bucket assembly, which is located at the front end of the tracked vehicle body. The roller structure, the pressure roller structure, and the auxiliary structure are all connected to the bucket assembly, and the roller structure, the pressure roller structure, and the auxiliary structure are distributed along the bucket assembly from front to back. The roller structure is used to compact the sand by vibration, the pressure roller structure is used to flatten the sand, and the auxiliary structure is used to provide buoyancy support on soft sand. Both the water supply structure and the liquid supply structure are connected to the tracked vehicle body. The water supply structure is used to spray water in front of the roller structure, and the liquid supply structure is used to spray sand-fixing agent at the pressure roller structure.
[0006] Furthermore, the bucket assembly includes a mounting bracket and a bucket body, the bucket body being connected to the front end of the tracked vehicle body via the mounting bracket, and the bucket body being used to level the slope.
[0007] Furthermore, the bucket assembly also includes a sand baffle plate, which is connected to the mounting bracket and is located on the side of the roller structure away from the pressure roller structure, with a gap between the sand baffle plate and the bottom surface of the bucket body.
[0008] Furthermore, the roller structure includes a bump roller and a hydraulic vibration motor, and the bump roller is connected to the mounting bracket via the hydraulic vibration motor.
[0009] Furthermore, the auxiliary structure includes a mounting cylinder, a movable rod, and an auxiliary wide wheel, wherein the mounting cylinder is connected to the mounting bracket; Both ends of the auxiliary wide wheel are connected to the mounting cylinder via corresponding movable rods.
[0010] Furthermore, a return spring is fixedly connected between the top surface of the movable rod and the inner wall of the mounting cylinder.
[0011] Furthermore, a damper is provided inside the mounting cylinder, and the damper is located in the return spring.
[0012] Furthermore, the pressure roller structure includes a flat roller and multiple precision flat rollers, both of which are connected to the bucket body, and the flat roller is located at the front end of the multiple precision flat rollers.
[0013] Furthermore, the water supply structure includes a water storage tank and a humidification tank. The water storage tank is connected to the tracked vehicle body, and the water storage tank is connected to the humidification tank through a pipeline. The humidification tank is connected to the bucket body, and the humidification tank is provided with multiple water nozzles. The humidification tank is located on the side of the roller structure away from the auxiliary structure.
[0014] Furthermore, the liquid supply structure includes a liquid storage tank and a spraying component. The liquid storage tank is connected to the tracked vehicle body, and the liquid storage tank is connected to the spraying component via a pipeline. The spraying element is provided in multiple and spaced apart, and the spraying element is located between the flat roller and the fine flat roller closest to the flat roller.
[0015] The present invention can achieve the following beneficial effects: This invention provides a sand leveling and stabilizing device, comprising a tracked vehicle body, a water supply structure, a liquid supply structure, a roller structure, an auxiliary structure, and a pressure roller structure. The tracked vehicle body includes a bucket assembly located at the front end of the vehicle body. The roller structure, pressure roller structure, and auxiliary structure are all connected to the bucket assembly and are distributed along the bucket assembly from front to rear. The roller structure is used to compact the sand through vibration, the pressure roller structure is used to flatten the sand, and the auxiliary structure is used to provide buoyancy support on soft sand. The water supply structure and the liquid supply structure are both connected to the tracked vehicle body.

[0016] In this invention, a bucket assembly is fixedly installed at the front end of the tracked vehicle body. This allows the bucket assembly to level the slope ahead and shovel sand into the bucket assembly as the tracked vehicle body moves forward. A pressure sensor mounted on the bucket assembly detects the sand entering, and a water pump within the water supply structure activates upon receiving data from the pressure sensor, spraying water outwards. The liquid supply structure is used to spray a solidifying agent onto the sand after the roller structure has compacted it, ensuring the sand remains in a stable, flat state.

[0028] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0029] Example 1 This embodiment provides a device for leveling and stabilizing sandy land, referring to... Figure 1 and Figure 2 The equipment for leveling and stabilizing sand includes a tracked vehicle body 1, a water supply structure 2, a liquid supply structure 3, a roller structure 4, an auxiliary structure 5, and a pressure roller structure. The tracked vehicle body 1 includes a bucket assembly 11, which is located at the front end of the tracked vehicle body 1. The roller structure 4, the pressure roller structure, and the auxiliary structure 5 are all connected to the bucket assembly 11, and are distributed from front to back along the bucket assembly 11. The roller structure 4 is used to compact the sand through vibration, the pressure roller structure is used to flatten the sand, and the auxiliary structure 5 is used to provide buoyancy support on the soft sand. The water supply structure 2 and the liquid supply structure 3 are both connected to the tracked vehicle body 1. The water supply structure 2 is used to spray water in front of the roller structure 4, and the liquid supply structure 3 is used to spray sand-stabilizing agent at the pressure roller structure.
[0030] The embodiments of the present invention at least alleviate the technical problems existing in the prior art, such as the inability to achieve the flatness required for photovoltaic panels, the easy settling due to poor compaction, and the failure of sand-fixing agents due to their remaining on the surface.
[0031] In this embodiment of the invention, a bucket assembly 11 is fixedly installed at the front end of the tracked vehicle body 1. This allows the bucket assembly 11 to level the slope ahead and shovel sand into the bucket assembly 11 as the tracked vehicle body 1 moves forward. Upon sensing the sand entering the bucket assembly 11, a pressure sensor mounted on the bucket assembly 11 activates a water pump within the water supply structure 2, spraying water out. The liquid supply structure 3 is used to spray a solidifying agent onto the sand after the roller structure 4 has compacted it, ensuring the sand remains in a stable, flat state.
[0032] Compared with the prior art, the sand leveling and sand fixation equipment provided in this embodiment of the invention, by setting a bucket assembly 11 at the front end of the tracked vehicle body 1, and installing a roller structure 4 and a pressure roller structure on the bucket assembly 11, can realize operations such as leveling, spraying water, compacting and solidifying the sand, so that the sand meets the usage requirements after solidification.
[0033] In an optional implementation of this embodiment, refer to Figure 1 , Figure 2 and Figure 3 The bucket assembly 11 includes a mounting bracket 111 and a bucket body 112. The bucket body 112 is connected to the front end of the tracked vehicle body 1 via the mounting bracket 111, and the bucket body 112 is used to level the slope.
[0034] Specifically: The bucket body 112 is connected to the front end of the tracked vehicle body 1 via the mounting bracket 111; when in use, the tracked vehicle body 1 is started, and as the tracked vehicle body 1 moves forward, the bucket body 112 is used to flatten the slope and allow sand to enter the bucket body 112.
[0035] Furthermore, refer to Figure 1 and Figure 3 The bucket assembly 11 also includes a sand baffle 113, which is connected to the mounting bracket 111. The sand baffle 113 is located on the side of the roller structure 4 away from the pressure roller structure, and there is a gap between the sand baffle 113 and the bottom surface of the bucket body 112.
[0036] Specifically, a sand baffle 113 is fixedly installed between the bucket body 112 and the roller structure 4. The sand baffle 113 is made of wear-resistant rubber material, and a certain gap is left between its lower end and the bottom surface of the bucket body 112. This design allows sand to pass through while effectively preventing sand and dust raised by the roller structure 4 during vibration compaction from splashing forward, thereby protecting the operating vision in front of the bucket body 112 and keeping the equipment clean.
[0037] In an optional implementation of this embodiment, refer to Figure 1 , Figure 2 and Figure 3The roller structure 4 includes a bump roller 41 and a hydraulic vibration motor 42. The bump roller 41 is connected to the mounting bracket 111 via the hydraulic vibration motor 42.
[0038] Specifically: the bump roller 41 is fixedly connected to the middle section of the bucket assembly 11, and a hydraulic vibration motor 42 for driving the bump roller 41 to vibrate is fixedly installed on the mounting bracket 111; when in use, the hydraulic vibration motor 42 is started to start the bump roller 41 to vibrate and rotate at the same time to achieve the purpose of compacting the sand.
[0039] In an optional implementation of this embodiment, refer to Figure 3 and Figure 4 The auxiliary structure 5 includes a mounting cylinder 51, a movable rod 52, and an auxiliary wide wheel 53. The mounting cylinder 51 is connected to the mounting bracket 111. The two ends of the auxiliary wide wheel 53 are respectively connected to the mounting cylinder 51 through the corresponding movable rod 52.
[0040] Specifically: Mounting cylinders 51 are fixedly connected to both sides of the lower end of the mounting bracket 111. Movable rods 52 are slidably mounted on the lower end of the mounting cylinders 51. Auxiliary wide wheels 53 are rotatably mounted on the bottom ends of the two movable rods 52. The auxiliary wide wheels 53 are low-pressure wide-base tires. The auxiliary wide wheels 53 are used to provide additional buoyancy support on soft sandy ground to prevent the whole machine from sinking on extremely soft road sections.
[0041] Furthermore, refer to Figure 4 A return spring 522 is fixedly connected between the top surface of the movable rod 52 and the inner wall of the mounting cylinder 51.
[0042] Specifically: A return spring 522 is fixedly connected between the inner wall of the mounting cylinder 51 and the top surface of the movable rod 52, so as to achieve a certain shock absorption and reset function through the return spring 522.
[0043] Furthermore, refer to Figure 4 A damper 521 is provided inside the mounting cylinder 51, and the damper 521 is located in the return spring 522.
[0044] Specifically: The mounting cylinder 51 is equipped with a damper 521 located in the return spring 522. The damper 521 is a hydraulic damper and together with the return spring 522, it forms a spring damping suspension system. It can automatically extend and retract according to the ground undulations, so that the auxiliary wide wheel 53 can always keep in contact with the ground. At the same time, it provides buffering when the equipment turns or encounters an impact, avoids rigid collision between the wheel set and the frame of the tracked vehicle body 1, and provides flexible support for the mounting bracket 111.
[0045] In an optional implementation of this embodiment, refer to Figure 2 and Figure 3The pressure roller structure includes a flat roller 6 and multiple fine flat rollers 7. The flat roller 6 and multiple fine flat rollers 7 are all connected to the bucket body 112, and the flat roller 6 is located at the front end of the multiple fine flat rollers 7.
[0046] Specifically, the bottom surface of the bucket body 112 has mounting holes for housing and installing the protruding roller 41, the flat roller 6, and multiple fine flat rollers 7. The flat roller 6 is located at the rear outlet of the bucket body 112, and the multiple fine flat rollers 7 are arranged sequentially behind the flat roller 6. In use, to ensure that the chemical sand-fixing agent is evenly applied to the surface of the sand after coarse compaction by the flat roller 6, optimal adhesion conditions are provided for the subsequent secondary compaction and finishing by the multiple fine flat rollers 7.
[0047] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 The water supply structure 2 includes a water storage tank 21 and a humidification tank 22. The water storage tank 21 is connected to the tracked vehicle body 1 and is connected to the humidification tank 22 through a pipeline. The humidification tank 22 is connected to the bucket body 112 and is provided with multiple water nozzles 221. The humidification tank 22 is located on the side of the roller structure 4 away from the auxiliary structure 5.
[0048] Specifically: the water pump in the water storage tank 21 can be a high-pressure plunger pump to provide sufficient spraying pressure to penetrate the surface sand. The bottom surface of the bucket body 112 is provided with a humidification trough 22, and a water outlet nozzle 221 connected to the water storage tank 21 is provided on the humidification trough 22. The humidification trough 22 extends laterally along the bottom surface of the bucket body 112, and its width matches the working width of the bucket body 112 to ensure that the humidification range completely covers the scraping width of the bucket body 112. Multiple water outlet nozzles 221 are arranged at equal intervals in the humidification trough 22 to form a continuous water curtain, making the humidification more uniform. The working surface of the bucket body 112 is inclined towards the opening, and a pressure sensor electrically connected to the water outlet nozzle 221 is fixedly installed on the working surface of the bucket body 112.
[0049] In an optional implementation of this embodiment, refer to Figure 1 and Figure 2 The liquid supply structure 3 includes a liquid storage tank 31 and a spraying component 32. The liquid storage tank 31 is connected to the tracked vehicle body 1, and the liquid storage tank 31 is connected to the spraying component 32 through a pipeline. Multiple spraying components 32 are provided and distributed at intervals, and the spraying components 32 are located between the flat roller 6 and the fine flat roller 7 closest to the flat roller 6.
[0050] Specifically: the water pump in the storage tank 31 is a metering pump, used to precisely control the spray flow of the chemical sand-fixing agent to avoid waste or uneven spraying; and multiple spraying components 32 are fixedly connected to the mounting bracket 111, located between the flat roller 6 and the fine flat roller 7 and connected to the storage tank 31. The spraying components 32 are fan-shaped atomizing nozzles with a spray angle of up to 110°, forming an overlapping coverage in the working width, ensuring that the chemical sand-fixing agent is evenly coated on the surface of the sand after coarse compaction by the flat roller 6, providing the best adhesion conditions for the subsequent secondary compaction and finishing by the fine flat roller 7.
[0051] It should be noted that the tracked vehicle body 1 cab also integrates a central control system, which is electrically connected to the hydraulic vibration motor 42, the water pump of the water tank 21, the water pump of the liquid tank 31, the pressure sensor, and the control valve group of the spraying component 32, respectively, to coordinate the collaborative operation of the various components.
[0052] This central control system has multiple preset operating modes, including "light compaction mode," "standard mode," and "heavy compaction mode." Operators can switch between these modes with a single click based on the type of sand, moisture content, and sand-fixing requirements. The system automatically matches the vibration frequency, humidification water volume, and chemical spraying amount, achieving intelligent operation. Simultaneously, the central control system also has a data recording function, capable of recording the operating area, water consumption, chemical consumption, and vibration compaction parameters in real time, facilitating subsequent construction management and effect evaluation.
[0053] During use, the user starts the tracked vehicle body 1, which causes the bucket body 112 to flatten the slope, allowing sand to enter the bucket body 112. The pressure sensor on the bucket body 112 detects the sand entering, and the water pump in the water tank 21 starts after receiving the data information transmitted by the pressure sensor. At this time, the water pump directs the water in the water tank 21 to the water nozzle 221, and humidifies the sand under the bucket body 112 through the water nozzle 221. Then, the hydraulic vibration motor 42 is started, which causes the convex roller 41 to vibrate and rotate simultaneously to achieve compaction. Then, the flat roller 6 is used for leveling. At the same time, the water pump in the storage tank 31 starts after receiving the command to start the hydraulic vibration motor 42. At this time, the water pump leads the chemical sand-fixing agent in the storage tank 31 to the spraying component 32, and the sand is fixed by the spraying component 32. After being atomized by the spraying component 32, the chemical sand-fixing agent is evenly covered on the surface of the sand after being coarsely compacted by the flat roller 6. Then, it is lightly pressed into the surface layer by the subsequent fine flat roller 7 to a depth of 2-3 cm, forming a dense crust layer with wind erosion resistance, effectively preventing sand particles from being lifted. The auxiliary wide wheel 53 maintains elastic contact with the ground throughout the equipment's movement. When encountering soft terrain, the movable rod 52 compresses the return spring 522 and damper 521, causing the auxiliary wide wheel 53 to sink and increase its ground contact area, providing additional buoyancy and preventing the equipment from sinking into quicksand. When the equipment passes through hard terrain, the return spring 522 pushes the movable rod 52 out, causing the auxiliary wide wheel 53 to lift off the ground or lightly touch the ground, reducing unnecessary frictional resistance. During the vibration compaction process of the protruding roller 41, the sand baffle 113 effectively blocks splashed sand, ensuring that the working areas of the spraying component 32 and the fine roller 7 are not covered by sand and dust, thereby maintaining operational effectiveness.
[0054] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
