Description

Technical Field

[0001] This invention relates to the field of hydroseeding equipment technology, and more specifically, to a grass seed hydroseeding device for grassland restoration. Background Technology

[0002] Grassland restoration refers to the process of restoring degraded or damaged grassland ecosystems to near their original ecological functions and productive states through a combination of human intervention and natural processes. Grassland restoration should adhere to the principle of prioritizing natural restoration and supplementing it with human intervention, promoting natural vegetation growth.

[0003] Hydroseeding is one of the main methods of grassland restoration. However, existing hydroseeding devices are suitable for slope protection and greening of rocky slopes and soil-rock slopes. It involves uniformly mixing soil, organic matter, binder, fertilizer, soil conditioner and other materials with grass seeds, and then spraying the mixture evenly onto the slope to form a substrate layer that can support plant growth and development, achieving ideal vegetation restoration or greening effects in a relatively short time.

[0004] Therefore, it is evident that using existing hydroseeding equipment for mulching relies primarily on human intervention. This results in areas where, after hydroseeding, the planted vegetation becomes dominant, leading to near-saturation of the original vegetation and hindering biodiversity development. This contradicts the principle of grassland restoration, which prioritizes natural recovery with human intervention as a secondary measure. Consequently, existing hydroseeding equipment is unsuitable for the natural restoration of grasslands.

[0005] Therefore, how to achieve auxiliary spraying during grassland restoration is an urgent problem to be solved in this technical field. Summary of the Invention

This follows the principle of natural restoration as the primary method and artificial intervention as a supplement, promoting the natural growth of grassland vegetation.

[0046] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] As per the instruction manual Figure 1 As shown, this embodiment provides a grass seed spraying device for grassland restoration, including:

[0048] Translation mechanism 1, mixing mechanism 2, adjusting mechanism 3 and spraying mechanism 4, and a controller for adjusting translation mechanism 1, mixing mechanism 2, adjusting mechanism 3 and spraying mechanism 4;

[0049] Translation mechanism 1 is used to perform equidistant translations on the grassland surface;

[0050] The mixing mechanism 2 is mounted on the translation mechanism 1. The mixing mechanism 2 includes a solid storage component 21, a liquid storage component 22, and a mixing component 23. The solid storage component 21 and the liquid storage component 22 are respectively connected to the mixing component 23.

[0051] The adjustment mechanism 3 includes a lifting component 31, a tilt adjustment component 32, and a deflection adjustment component 33. The lifting component 31 is mounted on the translation mechanism 1. The tilt adjustment component 32 is connected to the lifting component 31 in a transmission manner, and the deflection adjustment component 33 is connected to the tilt adjustment component 32 in a transmission manner.

[0052] The hydroseeding mechanism 4 includes two hydroseeding pipes 41, two support hoses 42, a variable frequency pump 43, and a grass seed injection component 44. The input end of the variable frequency pump 43 is connected to the mixing component 23, and the output end of the variable frequency pump 43 is connected to one end of the grass seed injection component 44. The other end of the grass seed injection component 44 is connected to one end of the two support hoses 42, and the other end of the support hoses 42 is connected to the hydroseeding pipes 41. The hydroseeding pipes 41 are connected to the deflection adjustment component 33. The hydroseeding pipes 41 are used to form a wavy hydroseeding path. The wavy hydroseeding paths formed by the two hydroseeding pipes 41 are opposite and intersect.

[0053] Understandably, during grassland restoration, the translation mechanism 1 is moved to the area to be restored. Based on the lifting height of the lifting component 31 and the tilt angle adjustment range of the tilt angle adjustment component 32, the initial position of the translation mechanism 1 in the area to be restored is adjusted. Based on the tilt angle adjustment range of the deflection adjustment component 33, the movement distance of the translation mechanism 1 is set by the controller. Subsequently, solid materials such as soil, organic matter, and fertilizer for hydroseeding are stored in the solid storage component 21, while water, adhesive, and amendments for hydroseeding are added to the liquid storage component 22 to mix and form a mixed solution. Grass seeds are added to the grass seed injection component 44. During hydroseeding, the solid storage component 21 delivers a fixed amount of solid material to the mixing component 23, and the liquid storage component... 22. A measured amount of mixed solution is injected into the mixing component 23. The mixing component 23 only mixes a measured amount of solid material and a measured amount of mixed solution, which is easy to mix and consumes little energy. After mixing, a spraying fluid is obtained. Subsequently, the variable frequency pump 43 delivers the spraying fluid to the grass seed injection component 44. When the spraying fluid flows through the grass seed injection component 44, the grass seeds are evenly injected into the spraying fluid. The spraying fluid injected with grass seeds flows through two support hoses 42 and is then sprayed out from two spraying pipes 41. During the spraying process of the two spraying pipes 41, under the restriction of the tilt angle adjustment component 32, the two spraying pipes 41 are always in a downward tilting state, so that the fluid sprayed from the two spraying pipes 41 can accurately act on the grassland ground, and the lifting component 31... Under the lifting action and the deflection adjustment component 33, the fluid sprayed from the two spray pipes 41 forms a wave-shaped spraying path. The wave-shaped spraying paths formed by the two spray pipes 41 are opposite and intersect to form a spraying grid on the grassland ground. When the lifting component 31 rises to its maximum height, the depression angle adjustment component 32 slowly adjusts the depression angle of the two spray pipes 41 to decrease, so as to extend the spraying path further. When the lifting component 31 descends to its minimum height, the depression angle adjustment component 32 slowly adjusts the depression angle of the two spray pipes 41 to increase, so as to extend the spraying path further. And during the process of the lifting component 31 rising, the pressure of the variable frequency pump 43 gradually increases, and the depression angle adjustment component 32 slowly adjusts the pressure of the two spray pipes 41 to increase the pressure of the two spray pipes 41. As the angle of depression of the spray pipe 1 increases, the pressure of the variable frequency pump 43 gradually increases to meet the needs of long-distance spraying. During the descent of the lifting component 31, the pressure of the variable frequency pump 43 gradually decreases. As the angle of depression of the two spray pipes 41 decreases slowly, the pressure of the variable frequency pump 43 gradually decreases to avoid short-distance high-pressure spraying, which would cause grass seeds to splash out from the spraying fluid. After the single-row spraying grid is completed, based on the deflection adjustment range of the deflection adjustment component 33, the controller controls the translation mechanism 1 to move a set distance, and then spraying forms another spraying grid. Adjacent spraying grids intersect. After the translation mechanism 1 performs multiple translations at equal intervals on the grassland ground, it sprays in the grassland restoration area to form a spraying net.Hydroseeding nets increase the organic matter content of the original grassland soil, improve soil structure, enhance water and fertilizer retention capacity, restore vegetation cover and biomass, strengthen ecosystem functions, and reserve sufficient growing space for the original grassland vegetation, thus achieving auxiliary hydroseeding during grassland restoration. This approach is conducive to adhering to the principle of natural restoration as the primary method and artificial intervention as a supplement, promoting the natural growth of grassland vegetation.

[0054] It should be noted that the translation mechanism 1 is equipped with a mobile power supply, which supplies power to the electrical equipment.

[0055] As per the instruction manual Figures 2-3 As shown, the translation mechanism 1 includes a connecting plate 11, a positioning plate 12, and multiple self-driven shock-absorbing wheels 13. The positioning plate 12 is slidably connected to the bottom of the connecting plate 11. The connecting plate 11 is rotatably connected to a first lead screw. The positioning plate 12 is driven by the first lead screw. The first lead screw is driven by a first servo motor 14. The multiple self-driven shock-absorbing wheels 13 are fixedly connected to the connecting plate 11. Multiple first positioning components 15 are connected to the connecting plate 11. Multiple second positioning components 16 are connected to the connecting plate 11.

[0056] The first positioning component 15 and the second positioning component 16 have the same structure. The first positioning component 15 includes a first servo electric cylinder 151, a pressure sensor 152 and a positioning rod 153. The first servo electric cylinder 151 is connected to the connecting plate 11. One end of the pressure sensor 152 is connected to the transmission rod of the first servo electric cylinder 151, and the other end of the pressure sensor 152 is connected to the positioning rod 153. A limiting plate 154 is integrally provided on the positioning rod 153.

[0057] Understandably, during the single-row spraying process, multiple first servo cylinders 151 on the connecting plate 11 extend, positioning rods 153 embed into the ground, and limiting plates 154 abut against the ground. Based on the pressure information fed back by pressure sensors 152, the controller adjusts the extension length of the multiple first servo cylinders 151 on the connecting plate 11 until the pressure information fed back by multiple pressure sensors 152 is the same, thus horizontally supporting the connecting plate 11 on the ground. Subsequently, the first servo motor drives the first lead screw 14 to rotate counterclockwise, and the first lead screw drives the positioning plate 12 to slide out from the connecting plate 11. After the positioning plate 12 slides out, multiple first servo cylinders 151 on the positioning plate 12 extend, positioning rods 153 embed into the ground, and limiting plates 154 abut against the ground. Based on the pressure information fed back by pressure sensors 152, the controller adjusts the extension length of the multiple first servo cylinders on the positioning plate 12. The 151 extends to the same length until the pressure information fed back by multiple pressure sensors 152 is the same, thereby horizontally supporting and erecting the positioning plate 12 on the ground. After the single row of spraying grid is completed, the multiple first servo electric cylinders 151 on the connecting plate 11 retract, and the first servo motor drives the first lead screw of 14 to rotate clockwise a set number of times. The connecting plate 11 slides along the positioning plate 12 a set distance. During the sliding process, multiple self-driven shock-absorbing wheels 13 cooperate to assist in the movement under the control of the controller to ensure the stability of the connecting plate 11 sliding along the positioning plate 12. After the connecting plate 11 slides into place along the positioning plate 12, the multiple first servo electric cylinders 151 on the connecting plate 11 extend to support and erect the connecting plate 11. Then, another spraying grid is formed. The connecting plate 11 and the positioning plate 12 slide and support and erect multiple times in sequence until a spraying net is formed in the grassland restoration area.

[0058] As per the instruction manual Figures 4-5 As shown, the solid storage component 21 includes a storage hopper 211, an agitator 212, and a screw conveyor 213. The storage hopper 211 is mounted on the translation mechanism 1. Multiple storage spaces 214 are formed within the storage hopper 211 by multiple partitions. The agitator 212 is arranged through the multiple storage spaces 214 of the storage hopper 211. Multiple sets of baffles 215 are provided on the agitator 212. Each set of baffles 215 is respectively set at the bottom of each storage space 214 with clearance. The agitator 212 is driven by a second servo motor 216. The bottom end of the storage hopper 211 is connected to the input end of the screw conveyor 213. The output end of the screw conveyor 213 is connected to the mixing component 23. The bottom of each storage space 214 is respectively connected to a flow-limiting plate 217, which is located below the baffles 215.

[0059] Understandably, solid materials such as soil, organic matter, and fertilizer for hydroseeding are stored in multiple storage spaces 214. When the stirring shaft 212 is not rotating, the solid materials in the multiple storage spaces 214 cannot enter the screw conveyor 213 due to the obstruction of the deflector plate 215. Before hydroseeding, the depth of each flow-limiting plate 217 inserted into each storage space 214 is adjusted to regulate the flow rate of each storage space 214 and meet the output requirements of different proportions of various solid materials. When a certain amount of solid material is conveyed into the mixing component 23, the controller controls the second servo... The servo motor 216 starts for a set time based on a set speed. The second servo motor 216 drives the stirring shaft 212 to rotate synchronously. The multiple sets of baffles 215 of the stirring shaft 212 are respectively in multiple storage spaces 214, driving the solid materials in each storage space 214 to flow into the screw conveyor 213. Each flow-limiting baffle 217 limits the outflow speed of the solid materials in each storage space 214, so that multiple solid materials enter the screw conveyor 213 in different amounts. The screw conveyor 213 then transports the different amounts of multiple solid materials into the mixing component 23.

[0060] It should be noted that the outer wall of the storage hopper 211 is provided with multiple positioning cylinders, and the flow limiting plate 217 is slidably disposed in the positioning cylinder. A compression bolt is connected through the positioning cylinder, and the compression bolt abuts against the flow limiting plate 217. The outer wall of the storage hopper 211 is provided with multiple oscillators, which are used to ensure the flowability of solid materials in the storage space 214.

[0061] As per the instruction manual Figure 6 As shown, the liquid storage assembly 22 includes a storage tank 221, an electric stirrer 222, and a metering pump 223. The storage tank 221 is mounted on the translation mechanism 1 and is used to store the mixed solution. The electric stirrer 222 is installed through the storage tank 221. The input end of the metering pump 223 is connected to the storage tank 221, and the output end of the metering pump 223 is connected to the mixing assembly 23.

[0062] Understandably, the water, adhesive, modifier, etc. used for hydroseeding are added into the storage tank 221 according to the required ratio, and stirred by the electric stirrer 222 to form a mixed solution in the storage tank 221. After the controller controls the metering pump 223 to start, the metering pump 223 injects a quantitative amount of mixed solution into the mixing component 23.

[0063] As per the instruction manual Figure 7As shown, the mixing assembly 23 includes a mixing chamber 231, a mixing shaft 232, and a drive motor 233. The mixing chamber 231 is provided with a mixing chamber 234 and a temporary storage chamber 235 arranged vertically at intervals. The mixing shaft 232 is disposed through the mixing chamber 234 and the temporary storage chamber 235. The mixing shaft 232 is connected to the drive motor 233. The top of the mixing shaft 232 is provided with a first stirring blade 236, which is located in the mixing chamber 234. The bottom of the mixing shaft 232 is provided with a second stirring blade 237, which is located in the temporary storage chamber 235. The mixing chamber 234 is connected to the solid storage assembly 21 and the liquid storage assembly 22. The temporary storage chamber 235 is connected to the input end of the variable frequency pump 43. An electric gate valve 238 is provided between the mixing chamber 234 and the temporary storage chamber 235.

[0064] Understandably, the drive motor 233 is in a state of continuous rotation, causing the mixing shaft 232 to drive the first stirring blade 236 to continuously stir in the mixing chamber 234, and the second stirring blade 237 to continuously stir in the temporary storage chamber 235. When solid materials and mixed solutions are injected into the mixing chamber 234, the controller controls the electric gate valve 238 to close, and the screw conveyor 213 then transports different amounts of various solid materials into the mixing chamber 234. After the metering pump 223 injects a quantitative amount of mixed solution into the mixing chamber 234, the first stirring blade 236 fully mixes the various solid materials and mixed solution to obtain the sprayed fluid. After injecting solid materials and mixed solution for a certain period of time, the controller controls... The electric gate valve 238 opens, and the spraying fluid in the mixing chamber 234 flows into the temporary storage chamber 235. The first stirring blade 236 accelerates the flow of the spraying fluid. Then, the controller controls the electric gate valve 238 to close, and solid materials and mixed solutions are injected into the mixing chamber 234 again. The variable frequency pump 43 continuously pumps and outputs the spraying fluid from the temporary storage chamber 235. The mixing chamber 234 continuously mixes solid materials and mixed solutions in small amounts and then continuously injects them into the temporary storage chamber 235 to ensure the continuity of spraying and reduce the energy consumption required for solid-liquid mixing. Meanwhile, the second stirring blade 237 continuously stirs in the temporary storage chamber 235 to prevent the spraying fluid in the temporary storage chamber 235 from settling and stratifying.

[0065] As per the instruction manual Figure 8As shown, the lifting assembly 31 includes a support frame 311, a bearing plate 312, and a third servo motor 313. The support frame 311 is connected to the translation mechanism 1. The two sides of the support frame 311 are rotatably connected to second lead screws 314 respectively. The top of the support frame 311 is connected to a T-shaped reducer 315 and two right-angle reducers 316. One end of the right-angle reducer 316 is driven by the second lead screw 314, and the other end of the right-angle reducer 316 is driven by the T-shaped reducer 315. The third servo motor 313 is driven by the T-shaped reducer 315. The bearing plate 312 is slidably connected in the support frame 311. The two ends of the bearing plate 312 are threadedly connected to the two second lead screws 314 respectively. The tilt angle adjustment assembly 32 is set on the bearing plate 312.

[0066] Understandably, during the spraying process of the two spray pipes 41, under the restriction of the tilt angle adjustment component 32, the two spray pipes 41 are always in a downward tilting state. When the third servo motor 313 rotates clockwise, it drives the second lead screw 314 to rotate clockwise through the cooperation of the T-type reducer 315 and the two right-angle reducers 316, so that the bearing plate 312 slides from bottom to top in the support frame 311, and the spraying path is formed from near to far. After the single row of spraying grid is completed, the controller controls the translation mechanism 1 to move a set distance, and then the third servo motor 313 rotates counterclockwise, so that the bearing plate 312 slides from top to bottom in the support frame 311, and the spraying path is formed from far to near. This alternating lifting and lowering is performed until the spraying net is formed in the grassland restoration area.

[0067] As per the instruction manual Figure 9 As shown, the tilt adjustment assembly 32 includes a base plate 321, an adjustment plate 322, and a second servo cylinder 323. An L-shaped support plate 324 is integrally provided at the tail end of the base plate 321. The tail end of the second servo cylinder 323 is hinged to the L-shaped support plate 324. The head end of the adjustment plate 322 is hinged to the base plate 321. A T-shaped slide groove is provided at the bottom end of the adjustment plate 322. A T-shaped slider is hinged to the head end of the second servo cylinder 323. The T-shaped slider is slidably connected in the T-shaped slide groove.

[0068] Understandably, when the second servo cylinder 323 is in the retracted state, the adjusting plate 322 is tilted on the base plate 321, so that the two spray pipes 41 are initially in a small downward angle. When the lifting assembly 31 descends to the minimum height, the second servo cylinder 323 slowly extends, and the T-shaped slider slides in the T-shaped groove, so that the adjusting plate 322 deflects counterclockwise, causing the downward angle of the two spray pipes 41 to gradually increase, so as to further extend the spraying path to the nearer side. When the lifting assembly 31 rises to the maximum height, the second servo cylinder 323 slowly retracts, and the T-shaped slider slides in the T-shaped groove, so that the adjusting plate 322 deflects clockwise, causing the downward angle of the two spray pipes 41 to gradually decrease, so as to further extend the spraying path to the farer side.

[0069] As per the instruction manual Figure 8 and Figure 10 As shown, the deflection adjustment assembly 33 includes a connecting cylinder 331, two turntables 332, and a fourth servo motor 333. Two spray pipes 41 are respectively hinged inside the connecting cylinder 331 and are arranged alternately. A rotating shaft 334 is rotatably connected inside the connecting cylinder 331. The rotating shaft 334 is located in the middle of the two spray pipes 41. A first gear 335 is connected to the middle of the rotating shaft 334. The two turntables 332 are respectively connected to the two ends of the rotating shaft 334. One end of a transmission rod 336 is hinged to each of the two turntables 332. The other end of the transmission rod 336 is hinged to the tail of the spray pipe 41. The fourth servo motor 333 is connected through the connecting cylinder 331. The fourth servo motor 333 is connected to a second gear 337, which meshes with the first gear 335.

[0070] Understandably, during the lifting and lowering of the support plate 312 within the support frame 311, or during the deflection of the adjusting plate 322, the fourth servo motor 333 continuously rotates at a set speed. The fourth servo motor 333 drives the first gear 335 to rotate synchronously via the second gear 337, causing the rotating shaft 334 to drive the two turntables 332 to rotate. The two turntables 332 respectively apply driving force to the tail of the spray pipe 41 via the transmission rod 336, causing the two spray pipes 41 to reciprocate laterally deflect within the connecting cylinder 331, thereby adjusting the spraying path of the two spray pipes 41. The spray path is wavy, and the two spray pipes 41 are staggered inside the connecting cylinder 331 to prevent the spray fluid from intersecting and colliding during the spraying process. The spray paths of the two spray pipes 41 intersect after spraying to the ground, thus forming a spraying grid. By changing the transmission rods 336 of different lengths, the distance between the crests and troughs of the wavy spraying path can be adjusted. By adjusting the speed of the fourth servo motor 333, the distance between the crests of the wavy spraying path can be adjusted, thereby ensuring the effect of auxiliary spraying.

[0071] As per the instruction manual Figures 11-12 As shown, the grass seed injection assembly 44 includes a base 441, a grass seed box 442, and two injection discs 443. The base 441 has two flow channels. One end of each flow channel is connected to the output end of the variable frequency pump 43 via a three-way pipe 444. The other ends of each flow channel are connected to connecting pipes 445, which are connected to a support hose 42. The grass seed box 442 is mounted on the base 441. Two discharge hoppers 446 are provided at the bottom of the grass seed box 442. Discharge channels 447 are provided at the bottom of each discharge hopper 446. 47. A through flow channel is provided, and an injection plate 443 is rotatably connected to the discharge channel 447. The bottom of the injection plate 443 is located in the flow channel. Multiple grooves 448 are symmetrically provided on the peripheral wall of the injection plate 443. Multiple drive plates 449 are integrally provided at both ends of the injection plate 443. Arc-shaped slots are provided on both sides of the bottom of the discharge channel 447. Sealing grooves are provided in the arc-shaped slots. The drive plates 449 are located in the arc-shaped slots. Two sealing rings 4410 are integrally provided on the peripheral wall of the injection plate 443. The sealing rings 4410 are slidably connected to the sealing grooves.

[0072] Understandably, when the variable frequency pump 43 continuously outputs the spraying fluid from the temporary storage chamber 235, the spraying fluid, pressurized by the variable frequency pump 43, enters the flow channel through the three-way pipe 444. As the spraying fluid flows towards the connecting pipe 445 within the flow channel, it contacts the drive plates 449 located within the flow channel. The flowing spraying fluid, through the cooperation of multiple drive plates 449, drives the injection disc 443 to rotate. When the injection disc 443 rotates, the grass seeds in the discharge channel 447 enter the groove 448 located above it after rotation. As the spraying fluid pushes the drive plates 449, the groove 448 containing the grass seeds rotates into the flow channel after the injection disc 443 rotates. The grass seeds in the groove 448 are carried out by the flowing spraying fluid and mixed into the spraying fluid. The spraying fluid mixed with grass seeds then enters the support hose 4 through the connecting pipe 445. 2. Subsequently, the seeds are sprayed out from the spray pipe 41, so that the speed at which the injection disc 443 injects grass seeds into the flow channel varies with the flow speed of the spraying fluid. The higher the flow speed of the spraying fluid, the faster the injection disc 443 injects grass seeds into the flow channel. The lower the flow speed of the spraying fluid, the slower the injection disc 443 injects grass seeds into the flow channel. This can adapt to different pressure changes of the variable frequency pump 43 and ensure the uniformity of grass seed distribution in the spraying fluid. The drive plate 449 is set in the arc-shaped groove, and a sealing groove is opened in the arc-shaped groove. Two sealing rings 4410 are integrally set on the peripheral wall of the injection disc 443. The sealing rings 4410 are slidably connected to the sealing groove so that the flow channel and the discharge channel 447 are sealed, preventing the spraying fluid in the flow channel from entering the discharge channel 447 under pressure.

[0073] It should be noted that the amount of grass seeds injected can be adjusted by replacing the injection disc 443 with different groove sizes 448.

[0074] As shown in the attached diagram of the instruction manual. Figure 13 As shown, the tail end of the spray pipe 41 is provided with a support rod 5, and the end of the support rod 5 is integrally provided with a first semi-circular arc plate 51. The first semi-circular arc plate 51 is provided with a first flexible pad 52. The first semi-circular arc plate 51 is connected to a second semi-circular arc plate 53 by bolts. The second semi-circular arc plate 53 is provided with a second flexible pad 54. The support hose 42 is located between the first semi-circular arc plate 51 and the second semi-circular arc plate 53. The first flexible pad 52 and the second flexible pad 54 abut against the outer wall of the support hose 42.

[0075] Understandably, the spray pipe 41 is in continuous motion during the spraying process, causing frequent stress concentration at the connection between the spray pipe 41 and the support hose 42. This can easily lead to breakage or detachment at the connection. Therefore, a support rod 5 is provided at the tail end of the spray pipe 41, and a first semi-circular arc plate 51 is integrally provided at the end of the support rod 5. A first flexible pad 52 is provided inside the first semi-circular arc plate 51. After the support hose 42 is placed into the first semi-circular arc plate 51, a second semi-circular arc plate 53 is connected to the first semi-circular arc plate 51 by bolts, so that... The first flexible pad 52 and the second flexible pad 54 abut against the outer wall of the supporting hose 42. When the spraying pipe 41 moves continuously during the spraying process, the first semi-circular plate 51 and the second semi-circular plate 53, together with the first flexible pad 52 and the second flexible pad 54, drive the supporting hose 42 to move synchronously with the spraying pipe 41. The first flexible pad 52 and the second flexible pad 54 buffer the supporting hose 42 to prevent damage to the supporting hose 42. This ensures that the connection between the spraying pipe 41 and the supporting hose 42 will no longer be subjected to concentrated stress, effectively preventing the connection from easily breaking or detaching.
