Description

Technical Field

[0001] This invention belongs to the field of slope ecological protection technology, specifically relating to a thick-layer substrate sprayed vegetation protection equipment and construction method. Background Technology

[0002] Greening of slopes along highways has always been an important environmental protection and beautification project. Traditional greening methods often suffer from problems such as long construction cycles, high maintenance costs, and slow growth cycles, which cannot meet the needs of rapid construction and beautification. To address this issue, thick-layer substrate sprayed vegetation protection technology has emerged.

[0003] This technology utilizes specialized spraying equipment to spray a mixture of vegetation seeds, fertilizer, and soil onto the slope surface, forming a thick vegetation cover. This effectively prevents soil erosion and improves the slope's resistance to erosion. It also boasts advantages such as short construction period, low maintenance cost, and good aesthetic effect, making it an ideal choice for highway slope greening. However, existing thick-layer substrate spraying vegetation protection technology requires the manual laying of a composite material net on the slope during construction to improve the stability and erosion resistance of the sprayed substrate. Due to the slope's gradient, workers must operate on the slope during construction, making the process difficult. The slope not only increases the risk of slipping or falling, but also affects construction efficiency. Furthermore, existing spraying equipment relies on manual operation of the spray gun, which is affected by the skill level and experience of the workers, making construction difficult and challenging to guarantee the thickness and uniformity of the spray. Summary of the Invention

An electric push rod is hinged to the platform above each support arm. The telescopic end of the electric push rod is set towards the spray frame and is hinged to the back of the spray frame. The electric push rod is connected to a controller, which can control all electric push rods to extend and retract synchronously.

[0009] Each support arm has a support rod at its bottom, and the other end of the support rod is connected to the top of the lifting platform.

[0010] The lifting platform includes a scissor lift frame and a base. The base is mounted on the cargo vehicle via the scissor lift frame. The spraying device is mounted on the base. The scissor lift frame is connected to a controller.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0031] This embodiment provides a thick-layer substrate sprayed vegetation protection device, such as... Figure 1-5 As shown, the system includes a cargo vehicle 1, a controller, a substrate storage tank, and a cement storage tank. The controller is connected to a control panel for receiving and executing commands sent by the control panel. The cargo vehicle 1 is equipped with a lifting platform 2 and a material supply device. A spraying device connected to the controller is installed on the top of the lifting platform 2. The lifting platform 2 includes a scissor lift frame 22 and a base 21. The base 21 is installed on the cargo vehicle 1 via the scissor lift frame 22. The scissor lift frame 22 is connected to the controller. The spraying device is installed on the base 21. The controller can drive the base 21 to move up and down in parallel by controlling the scissor lift frame 22, thereby adjusting the height of the spraying device.

[0032] The spraying device includes a platform 31, a spray frame 32, an angle adjustment mechanism 33, a lateral drive mechanism 34, a lifting mechanism 35, and a carrier plate 36. The platform 31 is fixedly installed on the top of the lifting platform 2. The spray frame 32 is arranged laterally in front of the platform 31 and is connected to the platform 31 through the angle adjustment mechanism 33. The controller can adjust the pitch angle of the spray frame 32 through the angle adjustment mechanism 33. Specifically:

[0033] The angle adjustment mechanism 33 includes a support arm 331 and an electric push rod 332. Multiple support arms 331 are fixed horizontally and parallel to one end of the platform 31 facing the spray frame 32. The other end of the support arm 331 is hinged to the back of the spray frame 32. An electric push rod 332 is hinged to the platform 31 above each support arm 331. The telescopic end of the electric push rod 332 is set facing the spray frame 32 and is hinged to the back of the spray frame 32. The electric push rod 332 is connected to the controller. The controller can control all the electric push rods 332 to telescopically extend and retract. When all the electric push rods 332 telescopically extend and retract, they will push and pull the spray frame 32 to rotate around the hinge end of the support arm 331, thereby adjusting the pitch angle of the spray frame 32.

[0034] Furthermore, each support arm 331 is provided with a support rod 333 at its bottom, and the other end of the support rod 333 is connected to the top of the lifting platform 2, thereby improving the support strength of the support arm 331.

[0035] The carrier plate 36 is slidably mounted on the spray frame 32 and is connected to the transverse drive mechanism 34. The controller can drive the carrier plate 36 to move laterally along the spray frame 32 through the transverse drive mechanism 34. The transverse drive mechanism 34 includes a screw 341 and a drive assembly 342. The carrier plate 36 has a threaded hole in the middle along the transverse direction. The drive screw 341 is fitted into the threaded hole in the middle of the carrier plate 36. The two ends of the screw 341 extend outward from the carrier plate 36 and are rotatably fixed on the side frame of the spray frame 32 on the adjacent side. The screw 341 is connected to the drive assembly 342. The drive assembly 342 is connected to the controller. When the controller drives the screw 341 to rotate through the drive assembly 342, the carrier plate 36 can only slide laterally along the spray frame 32, thus driving the carrier plate 36 to move.

[0036] Furthermore, there are several ways in which the carrier plate 36 can be slidably mounted on the spray frame 32. For example, a rectangular outer frame 321 is fitted onto the front end face of the spray frame 32, and a transverse slider 322 is provided inside the rectangular outer frame. Slide rails are provided on the inner walls of the rectangular outer frame on both the upper and lower sides of the transverse slider. The upper and lower ends of the transverse slider are fitted into the slide rails on the corresponding sides and can slide laterally along the slide rails inside the rectangular outer frame. A threaded hole is provided in the middle of the transverse slider for mounting a screw 341. The transverse slider extends outward from the rectangular outer frame and is fixed to the back of the carrier plate 36. The drive assembly 342 includes a drive unit connected to the controller. The motor 3422 and the drive shaft 3421 are mounted on the back of the spray frame 32 in a transverse rotational manner, and both ends of the drive shaft 3421 extend outward from the spray frame 32. The drive motor 3422 is mounted on the back of the spray frame 32 on one side of the drive shaft 3421 and is connected to the drive shaft 3421 in a transmission connection. Both ends of the screw 341 extend outward from the spray frame 32 and are connected to the drive shaft 3421 on the adjacent side in a transmission connection. There are various ways in which the two ends of the screw 341 are connected to the ends of the drive shaft 3421 on the adjacent side in a transmission connection, such as being connected to the drive belt through pulleys or being connected to the drive belt through gear meshing.

[0037] A substrate nozzle assembly 37 is vertically mounted on the front side of the carrier plate 36. A slider 38 is vertically slidably mounted on the carrier plate 36 of the substrate nozzle assembly 37. The slider 38 is connected to the lifting mechanism 35. When the carrier plate 36 moves laterally, the controller drives the slider to slide up and down synchronously through the lifting mechanism 35. The lifting mechanism 35 is mounted on the top of the carrier plate 36, so that the controller can drive the slider to slide up and down through the lifting assembly during the lateral movement of the carrier plate 36. A cement nozzle 39 is matched and mounted on the slider. The cement nozzle 39 and the substrate nozzle assembly 37 are connected to the cement storage tank and the substrate storage tank respectively through a material supply device. Specifically:

[0038] The substrate nozzle assembly 37 includes a nozzle seat 371 vertically mounted on a carrier plate 36. The nozzle seat 371 has a cavity and is connected to the discharge end of a material supply device. Multiple substrate nozzles 372, communicating with the cavity, are evenly spaced vertically on the front side of the nozzle seat 371. The nozzle ends of both the substrate nozzles 372 and the cement nozzles 39 face forward. The material supply device includes a substrate suction pump, a cement suction pump, a rinsing tank, a rinsing pipe, and a suction pipe. The discharge end of the substrate suction pump is connected to the substrate... The nozzle assembly 37 is connected, and the discharge end of the cement suction pump is connected to the substrate nozzle 372. Both the substrate suction pump and the cement suction pump are equipped with electrically controlled three-way valves connected to the controller. The first suction end of the electrically controlled three-way valve on the substrate suction pump is connected to the substrate storage tank through a suction pipe. The first suction end of the electrically controlled three-way valve on the cement suction pump is connected to the cement storage tank through a suction pipe. The second suction ends of the electrically controlled three-way valves on the substrate suction pump and the cement suction pump are connected to the flushing tank through a flushing pipe.

[0039] When using the thick substrate spraying vegetation protection equipment provided in this embodiment to carry out thick substrate spraying vegetation protection construction on highway slopes, firstly, move the equipment provided in this embodiment to the construction area, so that the spraying device faces the cleaned slope protection area. Then, send a preparatory command to the controller through the control panel according to the height and steepness of the slope protection area. The controller will divide the slope protection area into multiple construction layers from top to bottom according to the height 'a' of the single spray coverage area of ​​the spraying device. Then, the controller will control the lifting platform 2 to raise the spraying device to a matching height according to the height of the top construction layer. Then, control the angle adjustment mechanism 33 to adjust the pitch angle of the spraying frame 32 so that the spraying frame 32 tilts upward toward the top construction layer of the slope protection area.

[0040] Then, a cement mesh construction command is sent to the controller via the control panel. Upon receiving the command, the controller first controls the material supply device to draw cement slurry from the cement storage tank and spray it through cement nozzles 39 onto the slope protection area of ​​the top construction layer. During the cement slurry spraying process, the controller controls the lateral drive mechanism 34 to drive the platform 31 to move laterally back and forth. Each time the platform 31 moves laterally to its limit position and changes direction, the controller controls the lifting platform 2 to descend by a height a, causing the changed platform 31 to drive the cement nozzles 39 to spray cement onto the slope protection area of ​​the lower construction layer. Because the controller drives the slider to move up and down synchronously through the lifting mechanism 35 during the lateral movement of the platform 31, the spray trajectory of the cement slurry in each construction layer is sinusoidal. Once the cement slurry spraying of the bottom construction layer is completed, the cement mesh construction command is finished, and the controller will control various parts... The preparatory command is re-executed and reset. After the cement slurry hardens and the cement mesh is constructed, the substrate spraying command can be sent to the controller through the control panel to spray a thick layer of substrate onto the slope protection area layer by layer from top to bottom. After receiving the substrate spraying command, the controller will first control the material supply device to extract the substrate mixture from the substrate storage tank and spray it onto the slope protection area of ​​the top construction layer through the substrate nozzle group 37. During the cement slurry spraying process, the controller will control the transverse drive mechanism 34 to drive the platform 31 to move laterally back and forth. When the platform 31 moves laterally to the limit position and changes direction each time, the controller will control the lifting platform 2 to drop by a height a, thereby automatically spraying a thick layer of substrate onto the slope protection area layer by layer from top to bottom. When the thick layer of substrate of the bottom construction layer is sprayed, the substrate spraying command is completed, and the equipment can be moved laterally to the next construction area to carry out the slope thick layer substrate spraying vegetation protection construction.

[0041] Compared with existing thick-layer substrate sprayed vegetation protection technology, when using the thick-layer substrate sprayed vegetation protection equipment provided in this embodiment for highway slope thick-layer substrate sprayed vegetation protection construction, during the process of spraying cement slurry from the cement nozzle 39, the movement of the cement nozzle 39 is controlled by the cooperation between the lifting platform 2, the lateral drive mechanism 34, and the lifting mechanism 35. Multiple sinusoidal cement protrusions are sprayed from top to bottom on the slope protection area to form a cement net. This not only effectively supports the sprayed thick substrate, improving its stability and erosion resistance, but also eliminates the need for manual labor on the slope. This effectively solves the problem of existing thick-layer substrate sprayed vegetation protection technology requiring manual labor on the slope to lay composite material nets to improve the stability of the sprayed substrate. The system addresses issues related to the slope's stability and erosion resistance. When spraying thick-layer substrate, the lifting platform 2 and the transverse drive mechanism 34 work together to automatically spray the thick substrate layer by layer from top to bottom onto the slope protection area. This not only ensures the uniformity and consistency of the sprayed thick substrate, improving the overall stability and durability of the slope, but also reduces construction difficulty, increases construction efficiency, and reduces labor costs and construction time. Furthermore, during the spraying of cement slurry, an appropriate amount of polymer material can be added to improve the flexibility and impact resistance of the cement protrusions, thereby enhancing the stability and durability of the slope. After construction, the substrate suction pump and cement suction pump simultaneously extract flushing liquid from the flushing tank and spray it out through the corresponding nozzles, achieving flushing of the spraying pipeline and nozzles. Example

[0042] The difference between Example 2 and Example 1 lies in the structure of the lifting mechanism 35. In this example, the lifting mechanism 35 and the carrier plate 36 are linked in the thick substrate spraying vegetation protection equipment. When the support platform 31 moves, it drives the lifting mechanism 35 to drive the slider 38 to automatically and synchronously slide up and down. Specifically:

[0043] like Figure 4 and Figure 6As shown, the lifting mechanism 35 includes a vertical plate 351 that is horizontally slidably mounted on the top of the spray frame 32. The vertical plate 351 is connected to the carrier plate 36. A rack 352 is horizontally mounted on the top of the spray frame 32 behind the vertical plate 351. A fixed shaft 353 is vertically mounted on the back of the vertical plate 351 above the rack 352. A compound gear 354 is rotatably mounted on the fixed shaft 353. The compound gear 354 includes a traveling gear 3541 and a driving sprocket 3542 that are coaxially fixed together. The traveling gear 3541 meshes with the rack 352. A drive disc is rotatably mounted on the side of the front end of the vertical plate 351 away from the substrate nozzle assembly 37. The shaft 3551 of the drive disc extends rearward from the vertical plate 351 and is fixedly mounted with a driven sprocket 356. The driven sprocket 356 and the driving sprocket 3542 are connected by a transmission chain 358. When the carrier plate 36 is horizontally... When the moving drive mechanism 34 drives the lateral sliding, the carrier plate 36 will drive the vertical plate 351 to move synchronously. When the vertical plate 351 moves, the traveling gear 3541 in the compound gear 354 will drive the driving sprocket 3542 to rotate synchronously along the rack 352. When the driving sprocket rotates, it will drive the drive disk to rotate synchronously with the sliding of the carrier plate 36 through the transmission chain 358. A push-pull rod 357 is hinged at the eccentric part of the front end face of the drive disk. The other end of the push-pull rod 357 is hinged to the top of the slider. When the drive disk rotates, it will drive the push-pull slider to slide vertically back and forth through the push-pull rod 357. Compared with Embodiment 1, the lifting mechanism 35 in the thick substrate spraying vegetation protection equipment provided in this embodiment adopts a pure mechanical structure and uses the power of the lateral sliding of the carrier plate 36 as the lifting driving force. It does not require a controller to control its opening and closing, which reduces the maintenance cost and failure rate of the equipment. Example

[0044] The difference between Example 3 and Example 2 is that a reversing mechanism is provided on the slider 38, and the cement nozzle 39 is mounted on the slider 38 through the reversing mechanism. Specifically:

[0045] The reversing mechanism includes a mounting plate 61 fixedly connected to the slider 38. The mounting plate 61 is fixed to the front of the slider and can slide up and down synchronously with the slider. A lever 62 is slidably mounted on the mounting plate 61 along its lateral direction. The lever is driven by a lever assembly, which is connected to a controller to control the left and right sliding of the lever. The distance between the extreme sliding positions on the left and right sides of the lever is the same as the wavelength of the sinusoidal cement-soil platform. Specifically:

[0046] Mounting plate 61 has a horizontally mounted slide rail 63 with both ends sealed. The bottom surface of the slide rail has a horizontally opened groove 631 communicating with the interior. A lever 62 is fitted inside the slide rail and can slide left and right along it. A cement nozzle 39 is fitted onto the lever 62. A lever 621 is vertically fixed to the bottom surface of the lever 62. The lever 621 extends downward through the groove 631 and connects to the actuating assembly. The actuating assembly includes a dial 64 rotatably mounted on the mounting plate 61 below the middle of the slide rail. The dial 64 is driven by a lever motor, which is connected to a controller. The controller can drive the dial 64 to rotate at a fixed angle via the lever motor. A rod is installed at one end facing the lever 621, and a lever spring 65 is fitted onto the rod. The other end of the lever spring is fixedly fitted onto the lever 621. When the dial 64 rotates clockwise at a fixed angle, the lever spring pushes the lever block 62 to slide to the right along the slide rail 63 to its limit position. When the dial 64 rotates counterclockwise at a fixed angle to reset, the lever spring pushes the lever block 62 to slide to the left along the slide rail 63 to its limit position. In use, when the controller controls the reversal of the platform 31 through the transverse drive mechanism 34, the controller will synchronously control the wave component to drive the lever block 62 to move the cement nozzle 39 to the other side along the slide rail. Thus, when constructing the cement mesh, as... Figure 8 As shown, the crests of the lower sinusoidal cement protrusions can intersect with the troughs of the upper sinusoidal cement protrusions. By increasing the connection points between the cement meshes, the stability and impact resistance of the constructed cement mesh can be effectively improved.

[0047] Furthermore, the left and right sides of the slide rail 63 are symmetrically provided with electromagnets 66 connected to the controller. When the toggle block moves to one end of the slide rail 63, the controller will control the electromagnet on the same side to activate and fix the toggle block, thereby effectively improving the stability of the toggle block when spraying cement slurry. Conversely, when the toggle block moves to the other end, the controller will control the electromagnet to turn off. Example

[0048] This embodiment provides a method for spraying vegetation protection onto thick substrates, characterized by using the thick substrate spraying vegetation protection equipment provided in any one of embodiments 1-3, and including the following steps:

[0049] Step 1: Clear debris from the slope protection area, including loose soil and loose rocks;

[0050] Step 2: Divide the slope protection area into multiple construction zones in the transverse direction according to the spray width of the thick substrate spraying vegetation protection equipment;

[0051] Step 3: Using a thick-layer substrate spraying vegetation protection equipment, cement is sprayed layer by layer along a wave pattern to construct a cement net in each construction area from top to bottom;

[0052] Step 4: After the cement mesh has hardened, thick-layer substrate is sprayed layer by layer from top to bottom on each construction area using a thick-layer substrate spraying vegetation protection equipment.

[0053] Step 5: After construction is completed, the material supply device is controlled by the thick substrate spraying vegetation protection equipment controller to backflush the nozzles; and the slope protection area is regularly maintained.

[0054] Compared with existing thick-layer substrate spraying vegetation protection construction methods, the thick-layer substrate spraying vegetation protection construction method provided in this embodiment utilizes the coordination between the lifting platform 2, the lateral drive mechanism 34, and the lifting mechanism 35 to control the movement of the cement nozzle 39, spraying multiple sinusoidal cement protrusions from top to bottom on the slope protection area to form a cement net. This not only effectively supports the sprayed thick substrate, improving its stability and erosion resistance, but also eliminates the need for manual labor on the slope. This effectively solves the problem of existing thick-layer substrate spraying vegetation protection construction methods requiring manual labor on the slope to lay composite material nets to improve the stability and erosion resistance of the sprayed substrate. Furthermore, during the spraying of the thick substrate, it is also possible to utilize… The lifting platform 2 and the transverse drive mechanism 34 work together to automatically spray thick-layer substrate layer by layer onto the slope protection area from top to bottom. This not only ensures the uniformity and consistency of the sprayed thick-layer substrate, improving the overall stability and durability of the slope, but also reduces construction difficulty, increases construction efficiency, and reduces labor costs and construction cycle. In addition, the thick-layer substrate spraying vegetation protection construction method provided in this embodiment can also incorporate an appropriate amount of polymer material during the spraying of cement slurry to improve the flexibility and impact resistance of the cement protrusions, thereby enhancing the stability and durability of the slope. Furthermore, after construction, the substrate suction pump and the cement suction pump simultaneously extract the flushing liquid in the flushing tank and spray it out through the corresponding nozzles to achieve flushing of the spraying pipeline and nozzles.
