Description

Technical Field

[0001] The present invention relates to the technical field of spraying devices, and in particular to a grass seed spraying device for grassland restoration. Background Art

[0002] Grassland restoration refers to the process of restoring degraded or damaged grassland ecosystems to a state close to their original ecological functions and production through human intervention and natural processes. Grassland restoration should adhere to the principle of natural restoration as the primary approach, supplemented by human intervention, to promote the natural growth of vegetation.

[0003] Using a spraying machine to sow grass seeds is one of the main methods of grassland restoration. However, the existing spraying device is only suitable for slope protection and greening of rock slopes and soil-rock slopes. It mixes soil, organic matter, adhesives, fertilizers, soil improvers and other materials with grass seeds evenly, and then sprays them evenly onto the slope surface to form a matrix layer for plant growth and development, achieving ideal vegetation restoration or greening effects in a relatively short period of time.

[0004] This shows that using existing spraying devices for seeding and covering relies primarily on human intervention. Consequently, the vegetation in the area seeded by the existing spraying devices becomes dominated by the sprayed vegetation, saturating the space for vegetation growth and occupying the original space for grassland vegetation. This is detrimental to the development of biodiversity and does not conform to the principle of natural recovery as the primary approach, supplemented by human intervention, in grassland restoration. Therefore, existing spraying devices are not suitable for natural grassland restoration.

[0005] Therefore, how to achieve only auxiliary spraying during grassland restoration is a problem that needs to be solved urgently in this technical field. Summary of the Invention

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0021] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of the present invention, the terms "first", "second", etc. are used only to distinguish the description and should not be understood as indicating or implying relative importance.

[0022] As the instruction manual Figure 1 As shown, this embodiment provides a grass seed spraying device for grassland restoration, comprising: A translation mechanism 1, a mixing mechanism 2, an adjustment mechanism 3, and a spraying mechanism 4, and a controller for regulating the translation mechanism 1, the mixing mechanism 2, the adjustment mechanism 3, and the spraying mechanism 4; The translation mechanism 1 is used for translation at equal intervals on the ground of the grassland; The mixing mechanism 2 is provided on the translation mechanism 1 and 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; The adjustment mechanism 3 includes a lifting assembly 31, a pitch adjustment assembly 32, and a deflection adjustment assembly 33. The lifting assembly 31 is arranged on the translation mechanism 1, the pitch adjustment assembly 32 is transmission-connected to the lifting assembly 31, and the deflection adjustment assembly 33 is transmission-connected to the pitch adjustment assembly 32. The sowing mechanism 4 includes two sowing pipes 41, two supporting hoses 42, a variable frequency pump 43 and a grass seed injection assembly 44. The input end of the variable frequency pump 43 is connected to the mixing assembly 23, and the output end of the variable frequency pump 43 is connected to one end of the grass seed injection assembly 44. The other end of the grass seed injection assembly 44 is connected to one end of the two supporting hoses 42. The other end of the support hose 42 is connected to the sowing pipe 41. The sowing pipe 41 is transmission-connected to the deflection adjustment assembly 33. The sowing pipe 41 is used for sowing to form a wavy sowing path. The wavy sowing paths formed by the two sowing pipes 41 are opposite and intersecting.

[0023] It can be understood that when grassland restoration is carried out, the translation mechanism 1 is moved to the area to be repaired, and the initial position of the translation mechanism 1 in the area to be repaired is adjusted based on the lifting height of the lifting component 31 and the depression angle adjustment range of the depression angle adjustment component 32. Based on the deflection adjustment range of the deflection adjustment component 33, the movement spacing of the translation mechanism 1 is set by the controller, and then the soil, organic matter, fertilizer and other solid materials for spraying are stored in the solid storage component 21 respectively, and the water, adhesive, improver and other materials for spraying are put into the liquid storage component 22 to mix and form a mixed solution, and the grass seeds are put into the grass seed injection component 44; when spraying, the solid storage component 21 transports a certain amount of solid materials into the mixing component 23, and the liquid storage component 22 injects a certain amount of mixed solution into the mixing component 23, and the mixing component 23 only mixes a certain amount of solid material and a certain amount of mixed solution. The mixing difficulty is small and the energy consumption is low. After mixing, a spraying fluid is obtained; then the frequency conversion pump 43 transports the spraying fluid to the grass seed injection component 44. When the spraying fluid passes through the grass seed injection component 44, the grass seeds are evenly injected into the spraying fluid. The spraying fluid injected with grass seeds passes through the two supporting hoses 42 and is sprayed out by the two spraying pipes 41; during the spraying process of the two spraying pipes 41, under the restriction of the depression angle adjustment component 32, the two spraying pipes 41 are always in a downward state, so that the fluid sprayed out by the two spraying pipes 41 can accurately act on the ground of the grassland and be sprayed in the lifting component 31 Under the lifting action of the deflection adjustment component 33 and the deflection adjustment of the deflection adjustment component 33, the fluid sprayed out of the two spraying pipes 41 presents a wavy spraying path, and the wavy spraying paths formed by the two spraying pipes 41 are opposite and intersecting to form a spraying grid on the ground of the grassland. When the lifting component 31 rises to the maximum height, the depression angle adjustment component 32 slowly adjusts the depression angle of the two spraying pipes 41 to reduce, so as to further extend the spraying path to the distance. When the lifting component 31 falls to the minimum height, the depression angle adjustment component 32 slowly adjusts the depression angle of the two spraying pipes 41 to increase, so as to further extend the spraying path to the near; and in 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 two spraying pipes 4 1 increases, the pressure of the variable frequency pump 43 further 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, and the depression angle adjustment component 32 slowly adjusts the depression angle of the two spraying pipes 41 to decrease, and the pressure of the variable frequency pump 43 further gradually decreases to avoid short-distance high-pressure spraying, which causes grass seeds to splash out of the spraying fluid; after the single-row spraying grid is sprayed, based on the deflection adjustment range of the deflection adjustment component 33, the controller controls the translation mechanism 1 to move the set distance, and then sprays to form another spraying grid. The adjacent spraying grids intersect, and the translation mechanism 1 performs multiple equal-spaced translations on the ground of the grassland, and then sprays in the repaired area of ​​the grassland to form a spraying network;Through the spraying net, the organic matter content of the grassland's original soil is increased, soil structure is improved, water and fertilizer retention capacity is enhanced, vegetation cover and biomass are restored, ecosystem functions are enhanced, and ample growth space is reserved for the grassland's original vegetation. This makes spraying an auxiliary method for grassland restoration. This is conducive to adhering to the principle of natural restoration as the primary method, supplemented by human intervention, and promoting the natural growth of grassland vegetation.

[0024] It should be noted that the translation mechanism 1 is provided with a mobile power supply, which supplies power to the electrical equipment.

[0025] As the instruction manual Figure 2-Figure 3 As shown, the translation mechanism 1 includes a connecting plate 11, a positioning plate 12 and a plurality of 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 screw rod. The positioning plate 12 is transmission-connected to the first screw rod. The first screw rod is driven by a first servo motor 14. The plurality of self-driven shock-absorbing wheels 13 are fixedly connected to the connecting plate 11. The connecting plate 11 is connected to a plurality of first positioning assemblies 15. The connecting plate 11 is connected to a plurality of second positioning assemblies 16. The first positioning assembly 15 has the same structure as the second positioning assembly 16. The first positioning assembly 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 limit plate 154 is integrally provided on the positioning rod 153.

[0026] It can be understood that during the single-row grid spraying process, the multiple first servo electric cylinders 151 on the connecting plate 11 are extended, the positioning rod 153 is embedded in the ground, and the limit plate 154 is against the ground. The controller adjusts the extension length of the multiple first servo electric cylinders 151 on the connecting plate 11 based on the pressure information fed back by the pressure sensor 152 until the pressure information fed back by the multiple pressure sensors 152 is the same, thereby horizontally supporting the connecting plate 11 on the ground. Then the first servo motor drives the first screw rod 14 to rotate counterclockwise, and the first screw rod drives the positioning plate 12 to slide out of the connecting plate 11. After the positioning plate 12 slides out, the multiple first servo electric cylinders 151 on the positioning plate 12 are extended, the positioning rod 153 is embedded in the ground, and the limit plate 154 is against the ground. The controller adjusts the multiple first servo electric cylinders on the positioning plate 12 based on the pressure information fed back by the pressure sensor 152. 151 extends the length until the pressure information fed back by multiple pressure sensors 152 is the same, so that the horizontal support of the positioning plate 12 is set on the ground; after the single-row seeding grid is sprayed, the multiple first servo electric cylinders 151 on the connecting plate 11 retract, and the first servo motor drives the first screw 14 to rotate clockwise for a set number of circles, and the connecting plate 11 slides along the positioning plate 12 for a set distance. During the sliding process, the multiple self-driven shock-absorbing wheels 13 cooperate to perform auxiliary 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 set up the connecting plate 11, and then spray to form another seeding grid. The connecting plate 11 and the positioning plate 12 slide and support and set up multiple times in turn until a seeding network is formed in the grassland restoration area.

[0027] As the instruction manual Figure 4-Figure 5 As shown, the solid storage assembly 21 includes a storage hopper 211, a stirring shaft 212 and a screw conveyor 213. The storage hopper 211 is mounted on the translation mechanism 1. A plurality of storage spaces 214 are formed in the storage hopper 211 by a plurality of partitions. The stirring shaft 212 passes through the plurality of storage spaces 214 of the storage hopper 211. A plurality of groups of dial plates 215 are provided on the stirring shaft 212. Each group of dial plates 215 is respectively provided at the bottom of each storage space 214 with a clearance fit. The stirring shaft 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, and the output end of the screw conveyor 213 is connected to the mixing assembly 23. The bottom of each storage space 214 is respectively connected to a flow limiting card plate 217, and the flow limiting card plate 217 is located below the dial plate 215.

[0028] It can be understood that the soil, organic matter, fertilizer and other solid materials for spraying are stored in multiple storage spaces 214 respectively. 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 dial plate 215. Before spraying, the depth of each flow limiting card plate 217 extending into each storage space 214 is adjusted to regulate the flow rate of each storage space 214 to meet the output requirements of different proportions of multiple solid materials. When a certain amount of solid material is transported into the mixing component 23, the controller controls the second servo drive 217 to move the flow rate of each storage space 214 to the mixing component 23. The servo motor 216 starts the set time based on the set speed, and the second servo motor 216 drives the stirring shaft 212 to rotate synchronously. The multiple sets of paddles 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 card 217 limits the outflow speed of the solid material in each storage space 214, so that a variety of solid materials enter the screw conveyor 213 in different amounts, and the screw conveyor 213 then transports different amounts of multiple solid materials into the mixing component 23.

[0029] It should be noted that a plurality of positioning cylinders are provided on the outer wall of the storage hopper 211, and the flow limiting card plate 217 is slidably set in the positioning cylinder. The positioning cylinder is connected with an extrusion bolt, and the extrusion bolt abuts against the flow limiting card plate 217; a plurality of oscillators are provided on the outer wall of the storage hopper 211, and the oscillators are used to ensure the fluidity of the solid material in the storage space 214.

[0030] As the instruction manual Figure 6 As shown, the liquid storage component 22 includes a liquid storage tank 221, an electric agitator 222 and a metering pump 223. The liquid storage tank 221 is arranged on the translation mechanism 1. The liquid storage tank 221 is used to store the mixed solution. The electric agitator 222 is arranged through the liquid storage tank 221. The input end of the metering pump 223 is connected to the liquid storage tank 221, and the output end of the metering pump 223 is connected to the mixing component 23.

[0031] It can be understood that the water, adhesive, improver, etc. used for spraying are added into the liquid storage tank 221 according to the required ratio and stirred by the electric stirrer 222 to form a mixed solution in the liquid storage tank 221. After the controller controls the metering pump 223 to start, the metering pump 223 injects a certain amount of mixed solution into the mixing component 23.

[0032] As the instruction manual Figure 7As shown, the mixing component 23 includes a mixing bin 231, a mixing shaft 232 and a drive motor 233. A mixing chamber 234 and a temporary storage chamber 235 are arranged at upper and lower intervals in the mixing bin 231. The mixing shaft 232 is arranged in the mixing chamber 234 and the temporary storage chamber 235. The mixing shaft 232 is connected to the drive motor 233 in a transmission manner. A first stirring blade 236 is provided on the top of the mixing shaft 232, and the first stirring blade 236 is located in the mixing chamber 234. A second stirring blade 237 is provided at the bottom of the mixing shaft 232, and the second stirring blade 237 is located in the temporary storage chamber 235. The mixing chamber 234 is connected to the solid storage component 21 and the liquid storage component 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.

[0033] It can be understood that the driving motor 233 is in a state of continuous rotation, so that the mixing shaft 232 drives 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 chamber 235. When the solid material and the mixed solution are injected into the mixing chamber 234, the controller controls the electric gate valve 238 to close, and the screw conveyor 213 then conveys different amounts of multiple solid materials into the mixing chamber 234. After the metering pump 223 injects a fixed amount of mixed solution into the mixing chamber 234, the first stirring blade 236 fully mixes the multiple solid materials and the mixed solution to obtain a spraying fluid. After the solid material and the mixed solution are injected for a certain period of time, the controller controls The electric gate valve 238 is opened, and the seeding fluid in the mixing chamber 234 flows into the temporary storage chamber 235. The stirring of the first stirring blade 236 accelerates the flow of the seeding fluid. Then the controller controls the electric gate valve 238 to close, and the solid material and the mixed solution are injected into the mixing chamber 234 again. The frequency conversion pump 43 extracts the seeding fluid in the temporary storage chamber 235 and continuously outputs it. The mixing chamber 234 continuously mixes a small amount of solid material and mixed solution, and continuously injects it into the temporary storage chamber 235 to ensure the continuity of seeding and reduce the energy consumption required for solid-liquid mixing. The second stirring blade 237 continuously stirs in the temporary storage chamber 235 to prevent the seeding fluid in the temporary storage chamber 235 from settling and stratification.

[0034] As the instruction manual Figure 8As shown, the lifting assembly 31 includes a support frame 311, a carrying 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 respectively rotatably connected to the second screw rods 314. The top of the support frame 311 is connected to a T-type reducer 315 and two right-angle reducers 316. One end of the right-angle reducer 316 is transmission-connected to the second screw rod 314, and the other end of the right-angle reducer 316 is transmission-connected to the T-type reducer 315. The third servo motor 313 is transmission-connected to the T-type reducer 315. The carrying plate 312 is slidingly connected in the support frame 311. The two ends of the carrying plate 312 are respectively threadedly connected to the two second screw rods 314. The pitch angle adjustment assembly 32 is arranged on the carrying plate 312.

[0035] It can be understood that during the sowing process of the two spraying tubes 41, under the restriction of the depression angle adjustment component 32, the two spraying tubes 41 are always in a downward state, and when the third servo motor 313 rotates clockwise, the cooperation of the T-type reducer 315 and the two right-angle reducers 316 drives the second screw rod 314 to rotate clockwise, so that the supporting plate 312 slides from bottom to top in the support frame 311, and the sowing path is formed from near to far; after the single-row spraying grid sowing is completed, the controller controls the translation mechanism 1 to move the set distance, and then the third servo motor 313 rotates counterclockwise again, so that the supporting plate 312 slides from top to bottom in the support frame 311, and the sowing path is formed from far to near, and it is raised and lowered alternately in sequence until a spraying network is formed in the grassland restoration area.

[0036] As the instruction manual Figure 9 As shown, the pitch angle adjustment assembly 32 includes a base plate 321, an adjustment plate 322 and a second servo electric cylinder 323. The tail end of the base plate 321 is integrally provided with an L-shaped supporting plate 324. The tail end of the second servo electric cylinder 323 is hinged to the L-shaped supporting plate 324. The head end of the adjustment plate 322 is hinged to the base plate 321. The bottom end of the adjustment plate 322 is provided with a T-shaped slide. The head end of the second servo electric cylinder 323 is hinged with a T-shaped slider, and the T-shaped slider is slidably connected in the T-shaped slide.

[0037] It can be understood that when the second servo electric cylinder 323 is in the retracted state, the adjustment plate 322 is tilted and mounted on the bottom plate 321, so that the initial state of the two spraying tubes 41 is in a small-angle downward state; when the lifting assembly 31 descends to the minimum height, the second servo electric cylinder 323 slowly extends out, and the T-shaped slider slides in the T-shaped slide groove to deflect the adjustment plate 322 counterclockwise, driving the two spraying tubes 41 to gradually increase the depression angle, so as to further extend the spraying path closer; when the lifting assembly 31 rises to the maximum height, the second servo electric cylinder 323 slowly retracts, and the T-shaped slider slides in the T-shaped slide groove to deflect the adjustment plate 322 clockwise, driving the two spraying tubes 41 to gradually decrease the depression angle, so as to further extend the spraying path farther away.

[0038] As 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. The two seeding tubes 41 are respectively hinged in the connecting cylinder 331. The two seeding tubes 41 are staggered up and down. A rotating shaft 334 is rotatably connected in the connecting cylinder 331. The rotating shaft 334 is located in the middle position of the two seeding tubes 41. The middle position of the rotating shaft 334 is connected to the first gear 335. The two turntables 332 are respectively connected to the two end portions of the rotating shaft 334. One end of the transmission rod 336 is respectively hinged on the two turntables 332. The other end of the transmission rod 336 is hinged to the tail of the seeding tube 41. The fourth servo motor 333 is through-connected to the connecting cylinder 331. The fourth servo motor 333 is connected to the second gear 337. The second gear 337 is meshed with the first gear 335.

[0039] It can be understood that, during the lifting and lowering of the carrier plate 312 in the support frame 311 or the deflection of the adjustment plate 322, the fourth servo motor 333 rotates continuously at a set speed, and the fourth servo motor 333 drives the first gear 335 to rotate synchronously through the second gear 337, so that the rotating shaft 334 drives the two turntables 332 to rotate, and the two turntables 332 respectively apply driving force to the tail of the spraying tube 41 through the transmission rod 336, so that the two spraying tubes 41 perform reciprocating lateral deflection in the connecting cylinder 331, so that the spraying path of the two spraying tubes 41 is adjusted. The diameter is wavy, and the two spraying tubes 41 are staggered up and down in the connecting tube 331, so that the spraying fluids of the two spraying tubes 41 will not intersect and collide during the spraying process, and the spraying paths of the two spraying tubes 41 intersect after being sprayed on the ground, thereby forming a spraying grid after spraying. By replacing the transmission rods 336 of different lengths, the spacing between the crests and troughs of the wavy spraying path can be adjusted, and by adjusting the speed of the fourth servo motor 333, the crest spacing of the wavy spraying path can be adjusted, thereby ensuring the effect of auxiliary spraying.

[0040] As the instruction manual Figure 11-12 As shown, the grass seed injection assembly 44 includes a base 441, a grass seed box 442 and two injection disks 443. The base 441 is provided with two flow channels. One end of the two flow channels is connected to the output end of the variable frequency pump 43 through a three-way pipe 444. The other ends of the two flow channels are respectively connected to a docking pipe 445, and the docking pipe 445 is connected to the support hose 42. The grass seed box 442 is mounted on the base 441. Two discharge hoppers 446 are provided at the bottom end of the grass seed box 442. The bottom end of the discharge hopper 446 is provided with a discharge channel 447. The discharge channel 448 is provided with a discharge channel 449. 47 is provided with a through flow channel, the injection disk 443 is rotatably connected in the discharge channel 447, the bottom of the injection disk 443 is located in the flow channel, a plurality of grooves 448 are symmetrically provided on the peripheral wall of the injection disk 443, a plurality of drive plates 449 are integrally provided at both ends of the injection disk 443, arc-shaped notches are provided on both sides of the bottom of the discharge channel 447, a sealing groove is provided in the arc-shaped notch, the drive plate 449 is located in the arc-shaped notch, two sealing ring plates 4410 are integrally provided on the peripheral wall of the injection disk 443, and the sealing ring plates 4410 are slidably connected to the sealing groove.

[0041] It can be understood that when the variable frequency pump 43 extracts the seeding fluid in the temporary storage chamber 235 and continuously outputs it, the seeding fluid pressurized by the variable frequency pump 43 enters the flow channel through the three-way pipe 444. In the process of the seeding fluid flowing from the flow channel to the docking pipe 445, the seeding fluid contacts the driving plate 449 located in the flow channel. The flowing seeding fluid drives the injection disk 443 to rotate through the cooperation of multiple driving plates 449. When the injection disk 443 rotates, the grass seeds in the discharge channel 447 enter the groove 448 located above after the rotation. As the seeding fluid pushes the driving plate 449, after the injection disk 443 rotates, the groove 448 containing the grass seeds rotates and enters the flow channel. The grass seeds in the groove 448 are carried out by the flowing seeding fluid and mixed into the seeding fluid. The seeding fluid mixed with the grass seeds then enters the support hose 4 through the docking pipe 445. 2. It is then sprayed out by the spraying pipe 41, so that the speed at which the injection disc 443 injects grass seeds into the flow channel changes with the flow speed of the spraying fluid. When the flow speed of the spraying fluid is greater, the speed at which the injection disc 443 injects grass seeds into the flow channel is faster. When the flow speed of the spraying fluid is reduced, the speed at which the injection disc 443 injects grass seeds into the flow channel is reduced, thereby being able to adapt to different pressure changes of the variable frequency pump 43 and ensuring the uniformity of the distribution of grass seeds in the spraying fluid; and the driving plate 449 is arranged in the arc-shaped notch, and a sealing groove is provided in the arc-shaped notch, and two sealing ring plates 4410 are integrally provided on the peripheral wall of the injection disc 443, and the sealing ring plates 4410 are slidably connected to the sealing groove, so that the flow channel and the discharge channel 447 are sealed to prevent the spraying fluid in the flow channel from entering the discharge channel 447 under the action of pressure.

[0042] It should be noted that by replacing the injection disk 443 with a groove 448 of different sizes, the amount of grass seeds injected can be adjusted.

[0043] As shown in the attached figure of the instruction manual Figure 13 As shown, a support rod 5 is provided at the tail of the spraying tube 41, and a first semi-circular plate 51 is integrally provided at the end of the support rod 5, a first flexible pad 52 is provided in the first semi-circular plate 51, the first semi-circular plate 51 is connected to a second semi-circular plate 53 by bolts, a second flexible pad 54 is provided in the second semi-circular plate 53, and the support hose 42 is located between the first semi-circular plate 51 and the second semi-circular plate 53, and the first flexible pad 52 and the second flexible pad 54 are against the outer wall of the support hose 42.

[0044] It can be understood that the spraying tube 41 is in a state of continuous movement during the spraying process, so that the connection between the spraying tube 41 and the support hose 42 will be frequently subjected to concentrated stress, which may cause the connection between the spraying tube 41 and the support hose 42 to be easily broken and separated; therefore, a support rod 5 is provided at the tail end of the spraying tube 41, and a first semi-circular plate 51 is integrally provided at the end of the support rod 5. A first flexible pad 52 is provided in the first semi-circular plate 51. After the support hose 42 is placed in the first semi-circular plate 51, the second semi-circular plate 53 is connected to the first semi-circular plate 51 by bolts so that The first flexible pad 52 and the second flexible pad 54 are in contact with the outer wall of the support hose 42. When the spraying tube 41 continues to move during the spraying process, the first semi-circular plate 51 and the second semi-circular plate 53 cooperate with the first flexible pad 52 and the second flexible pad 54 to drive the support hose 42 to move synchronously with the spraying tube 41, and the first flexible pad 52 and the second flexible pad 54 buffer the support hose 42 to avoid damage to the support hose 42. In this way, the connection between the spraying tube 41 and the support hose 42 will no longer be subjected to concentrated stress, effectively avoiding the situation where the connection is prone to breakage and detachment.
