Description

Technical Field

[0001] This invention relates to the field of mine soil remediation equipment technology, specifically to a spraying device for mine soil remediation for ecological and environmental protection. Background Technology

[0002] The mine soil remediation device for ecological and environmental protection is a specialized environmental protection equipment specifically designed to address core environmental problems caused by mining, such as soil pollution, loss of soil and water conservation capacity, and degradation of ecological functions. It integrates soil physicochemical property improvement and full-process environmental risk management for environmental protection and ecological restoration. Its core objectives are to eliminate environmental health risks of mine soil, block the spread of soil and water pollution, and restore soil environmental carrying capacity and ecological self-purification capacity.

[0003] In the process of mine soil remediation, high-pressure hydroseeding equipment is often used to spray a mixture of grass seeds, fertilizers, and binders with water onto the slope to form an topsoil layer needed for plant growth and to remediate the soil. However, the hydroseeding mixture usually contains viscous slurry such as fibers and soil, which has poor fluidity and may clog the nozzle of the spray gun, affecting the continuity of hydroseeding. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a spraying device for mine soil remediation in ecological environmental protection, comprising a spraying vehicle, a water pump fixedly connected to the top of the spraying vehicle, and further comprising: The main structure is fixedly mounted on the top of the spraying vehicle; The diversion mechanism is fixedly installed on the inner wall of the main structure; A sliding mechanism is installed on the inner wall of the main body. In operation, the operator first connects the spraying vehicle to an external tractor, which then moves the spraying vehicle. When it is necessary to remediate the mine soil, the operator adds a mixture of grass seeds, fiber, soil, and adhesive with water to the spraying vehicle to form a slurry. Then, the water pump is started to draw the slurry from the spraying vehicle into the main structure, which then sprays the slurry onto the mine soil to remediate it.

[0005] Preferably, the main structure includes: Material conveying assembly, which is fixedly installed on the top of the spraying vehicle; The spraying assembly is rotatably mounted on the inner wall of the conveying assembly.

[0006] Preferably, the diversion mechanism includes: A flow guiding component is fixedly installed on the inner wall of the spraying component; The pusher component slides along the inner wall of the spraying component.

[0007] Preferably, the sliding mechanism includes: The unblocking component is slidably installed on the inner wall of the spraying component; The cleaning component is slidably set on the inner wall of the spraying component.

[0008] Preferably, the material conveying assembly includes a liquid conveying pipe fixedly connected to the top of the inner wall of the spraying vehicle, and an inlet pipe is connected through the left side of the inner wall of the spraying vehicle. The bottom inlet of the water pump is fixedly connected to the top of the inlet pipe, and the water delivery end on the back of the outer wall of the water pump is fixedly connected to the front of the delivery pipe. In the process of mine soil remediation, the slurry in the spraying vehicle is drawn into the inlet pipe by starting the water pump, and then enters the water pump through the inlet pipe. The slurry is then sent into the delivery pipe through the water delivery end of the water pump.

[0009] Preferably, the spraying assembly includes a spray gun mounted on the top of the spraying vehicle, and a sealing ring is fixedly connected to the outer wall of the spray gun; The outer wall of the sealing ring is rotatably connected to the right side of the inner wall of the infusion tube, and a nozzle is fixedly connected to the back of the spray gun. The slurry that enters the infusion tube will then enter the spray gun and finally be sprayed onto the soil through the nozzle.

[0010] Preferably, the flow guiding component includes two mounting holes 1 opened in the inner wall of the spray gun, and a flow guiding pipe 1 is provided on the top of the spraying vehicle, and the outer wall of the flow guiding pipe 1 is fixedly connected to the inner wall of the two mounting holes 1. The inner wall of the spray gun has two mounting holes 2. The top of the spraying vehicle is equipped with a guide pipe 2. The side of the guide pipe 2 closest to the guide pipe 1 is fixedly connected to the inner wall of the two mounting holes 2. A guide block is fixedly connected to the inner wall of the spray gun. The nozzle is widened at the side of the spray gun away from the nozzle by the guide block. When the slurry flowing inside the spray gun comes into contact with the guide block, it is split into two streams and enters the first guide pipe and the second guide pipe respectively. The slurry will flow back into the spray gun through the first guide pipe and the second guide pipe, and finally be sprayed out of the nozzle towards the mine soil. During the spraying of the slurry, the operator can adjust the spray angle by rotating the spray gun.

[0011] Preferably, the actuating component includes a flow-dividing cavity formed on the inner wall of the spray gun, a piston block is slidably connected to the inner wall of the flow-dividing cavity, and a sealing ring is fixedly connected to the outer wall of the piston block; During the continuous spraying of slurry into the mine soil, as the nozzle diameter gradually decreases, if fibers and large soil clods in the slurry form a bridging structure within the nozzle, it will gradually clog the nozzle. When the nozzle is clogged, the amount of slurry sprayed will be greatly reduced, and the slurry in the spray gun will concentrate in the distribution chamber. The pressure of the slurry will push the piston block to move.

[0012] Preferably, the unblocking component includes a spring ring slidably connected to the inner wall of the spray gun, an unblocking rod fixedly connected to the side of the spring ring away from the piston block, and a retaining ring fixedly connected to the inner wall of the spray gun. A sealing ring is fixedly connected to the inner wall of the fixed ring. The inner wall of the sealing ring is slidably connected to the outer wall of the unblocking rod. The side of the spring ring away from the fixed ring is fixedly connected to the side of the piston block close to the fixed ring. When the piston block moves, it drives the spring ring to move, causing the spring ring to be compressed and accumulate rebound force. The movement of the spring ring will drive the unblocking rod to move towards the nozzle. When the unblocking rod comes into contact with the accumulated fibers and soil particles, it will push such blockages out of the nozzle and unblock the nozzle. At this point, the blockage inside the nozzle is cleared, and the slurry can be quickly sprayed out of the nozzle. The squeezing pressure on the piston block also decreases, and the rebound force of the spring ring is released, pushing the piston block back to its original position. The piston block is moved by the slurry pressure, which in turn drives the unblocking rod to clear the nozzle, thus achieving automatic unblocking. This solves the problem of needing to stop the machine for cleaning after the nozzle is blocked, allowing the nozzle to spray continuously and stably, improving work efficiency.

[0013] Preferably, the cleaning component includes an annular scraper slidably connected to the inner wall of the diversion chamber, and a connecting rod is fixedly connected to the side of the annular scraper near the piston block; The outer wall of the connecting rod is rotatably connected to the inner wall of the piston block, and a sealing ring is fixedly connected to the inner wall of the piston block. The inner wall of the sealing ring is rotatably connected to the outer wall of the connecting rod. The outer wall of the connecting rod is provided with a spiral groove, and a ball rod is fixedly connected to the top of the inner wall of the diversion cavity. The bottom of the ball rod is slidably connected to the inner wall of the spiral groove. When the piston block moves, it pushes the connecting rod to move synchronously. The connecting rod will drive the annular scraper to move together. Because the ball rod limits the spiral groove, the ball rod will generate a lateral thrust on the groove wall of the spiral groove during the movement of the connecting rod, pushing the connecting rod to rotate. This allows the connecting rod to rotate while sliding, and the connecting rod will drive the annular scraper to rotate. When the piston block returns to its original position, it will push the annular scraper to return to its original position as well, and drive the connecting rod to reset. During the return process of the connecting rod, the ball screw will cause the connecting rod to rotate again, which in turn drives the annular scraper to rotate. When the annular scraper rotates, its outer wall will scrape off the slurry adhering to the inner wall of the diversion cavity. Meanwhile, during the sliding process of the annular scraper, its inclined surface can scrape off the slurry on the inner wall of the diversion cavity again. Through the above-mentioned double scraping action, the slurry adhering to the inner wall of the diversion cavity can be fully removed, significantly reducing the amount of slurry adhering to the outer wall of the piston block during the piston block return process. This effectively prevents excessive slurry from adhering to the outer wall of the piston block during the piston block return process. If the nozzle continues to spray, the adhering slurry gradually solidifies on the outer wall of the piston block, which will increase the sliding resistance of the piston block and affect the pushing effect of the subsequent slurry pressure on the piston block, thereby reducing the cleaning efficiency when the nozzle is blocked again. By enlarging the nozzle at the right side of the guide block, when the slurry flows to this enlarged area, the increased nozzle diameter leads to a larger flow area and a corresponding decrease in slurry velocity. This reduces the direct impact of the slurry and internal grass seeds on the guide block, effectively preventing the grass seeds from rapidly impacting the guide block when they come into contact with it. This protects the germination activity of the grass seeds, ensuring normal seedling emergence and growth of subsequent vegetation, and thus guaranteeing the overall effectiveness of mine soil remediation.

[0014] The present invention has the following beneficial effects: (1) When using this invention, the water pump is started to draw the slurry in the spraying vehicle into the inlet pipe, and then into the spray gun through the inlet pipe. Finally, it is sprayed out towards the mine soil through the nozzle. During the continuous spraying of slurry into the mine soil, if the nozzle is blocked, the amount of slurry sprayed will be greatly reduced. The slurry pressure in the spray gun will push the piston block to move, which will drive the spring ring to move, and drive the unblocking rod to move towards the nozzle. The unblocking rod will push the blockage out of the nozzle, unblock the nozzle, realize automatic unblocking, solve the problem of needing to stop the machine to clean after the nozzle is blocked, and make the nozzle continuously and stably spray, thus improving the work efficiency.

[0015] (2) In this invention, when the piston block moves, it will push the connecting rod and the annular scraper to move together. The ball rod forms a limit on the spiral groove, so that the connecting rod can rotate while sliding, which will drive the annular scraper to rotate. When the piston block returns to its original position, it will push the annular scraper to return to its original position together. The annular scraper will rotate when it returns to its original position through the cleaning component. Its outer wall will scrape off the slurry attached to the inner wall of the diversion cavity, which will significantly reduce the amount of slurry attached to its outer wall during the piston block's return process. This effectively prevents too much slurry from being attached to the outer wall of the piston block during the piston block's return process. If the nozzle continues to spray, the attached slurry will gradually solidify on the outer wall of the piston block, which will increase the sliding resistance of the piston block and affect the pushing effect of the subsequent slurry pressure on the piston block, thereby reducing the cleaning efficiency when the nozzle is blocked again.

[0016] (3) In this invention, the slurry after being diverted by the guide block enters the first guide tube and the second guide tube. Since the inner diameter of the two is much smaller than the inner diameter of the spray gun, the flow rate of the slurry will be significantly accelerated. When the slurry flows into the spray gun again along the first guide tube, it will impact the slurry in the spray gun, causing the slurry in the spray gun to generate turbulence, which will disperse the fibers that are about to overlap and reduce the solid matter that agglomerates at the nozzle. In addition, the slurry flowing out from the second guide tube will impact the inner wall of the nozzle outlet, which will apply a lateral impact force to the fiber bridging structure that overlaps at the nozzle outlet, making it easier to impact the newly formed bridging structure to be flushed out of the nozzle, continuously cleaning the nozzle where it is easy to accumulate, and preventing nozzle blockage from the source.

[0017] (4) In this invention, by enlarging the diameter of the spray gun on the right side of the guide block, when the slurry flows to the enlarged area, the flow area increases accordingly due to the increased diameter of the spray gun, and the slurry flow velocity decreases accordingly, thereby reducing the direct impact of the slurry and the grass seeds inside on the guide block. This effectively prevents the grass seeds in the slurry from rapidly impacting the guide block when they come into contact with it, which could easily cause damage to the grass seeds. This protects the germination activity of the grass seeds, ensures the normal emergence and growth of subsequent vegetation, and thus ensures the overall effect of mine soil remediation.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figures 1-5 This invention relates to a spraying device for mine soil remediation in ecological environment protection, comprising a spraying vehicle 13, a water pump 14 fixedly connected to the top of the spraying vehicle 13, and further comprising: Main structure 1, which is fixedly installed on the top of the spraying vehicle 13; Diversion mechanism 2 is fixedly installed on the inner wall of the main body mechanism 1; Sliding mechanism 3 is installed on the inner wall of the main body 1; In operation, the operator first connects the spraying vehicle 13 to an external tractor, which then moves the spraying vehicle 13. When it is necessary to remediate the mine soil, the operator adds a mixture of grass seeds, fiber, soil, adhesive, and water to the spraying vehicle 13 and mixes it into a slurry. Then, the water pump 14 is started to draw the slurry from the spraying vehicle 13 into the main body 1, and the slurry is then sprayed onto the mine soil through the main body 1 to remediate the soil.

[0023] Main body 1 includes: Material conveying assembly 11 is fixedly mounted on the top of the spraying vehicle 13; The spraying assembly 12 is rotatably mounted on the inner wall of the conveying assembly 11.

[0024] Diversion mechanism 2 includes: The flow guiding component 21 is fixedly disposed on the inner wall of the spraying component 12; Push component 22 is slidably disposed on the inner wall of spray component 12.

[0025] The sliding mechanism 3 includes: Unblocking component 31 is slidably disposed on the inner wall of spraying component 12; The cleaning component 32 is slidably disposed on the inner wall of the spraying component 12.

[0026] Example 2, please refer to Figures 3-9 The present invention is a spraying device for a mine soil remediation device for ecological environmental protection. Based on Example 1, the material conveying component 11 includes a liquid conveying pipe 111 fixedly connected to the top of the inner wall of the spraying vehicle 13, and an inlet pipe 112 is connected through the left side of the inner wall of the spraying vehicle 13. The bottom inlet of the water pump 14 is fixedly connected to the top of the inlet pipe 112, and the water delivery end on the back of the outer wall of the water pump 14 is fixedly connected to the front of the delivery pipe 111. In the process of mine soil remediation, the slurry in the spraying vehicle 13 is drawn into the inlet pipe 112 by starting the water pump 14, and then enters the water pump 14 through the inlet pipe 112. The slurry is then sent into the delivery pipe 111 through the water delivery end of the water pump 14.

[0027] The spraying assembly 12 includes a spray gun 121 mounted on the top of the spraying vehicle 13, and a sealing ring is fixedly connected to the outer wall of the spray gun 121; The outer wall of the sealing ring is rotatably connected to the right side of the inner wall of the infusion tube 111, and the nozzle 122 is fixedly connected to the back of the spray gun 121. The slurry that enters the infusion tube 111 will enter the spray gun 121 and finally be sprayed onto the soil through the nozzle 122.

[0028] The flow guiding assembly 21 includes two mounting holes 1 opened in the inner wall of the spray gun 121, and a flow guiding pipe 211 is provided on the top of the spraying vehicle 13. The outer wall of the flow guiding pipe 211 is fixedly connected to the inner wall of the two mounting holes 1. The inner wall of the spray gun 121 has two mounting holes 2. The top of the spraying vehicle 13 is provided with a guide pipe 212. The side of the guide pipe 212 near the guide pipe 11 is fixedly connected to the inner wall of the two mounting holes 2. The inner wall of the spray gun 121 is fixedly connected with a guide block 213. The guide block 213 is enlarged at the spray gun 121 on the side away from the nozzle 122. When the slurry flowing in the spray gun 121 comes into contact with the guide block 213, it will be divided into two streams by the guide block 213, which will enter the first guide pipe 211 and the second guide pipe 212 respectively. The slurry will flow back into the spray gun 121 along the first guide pipe 211 and the second guide pipe 212, and finally be sprayed out towards the mine soil through the nozzle 122. During the process of spraying the slurry through the nozzle 122, the operator can adjust the spray angle by rotating the spray gun 121.

[0029] The push assembly 22 includes a flow-dividing cavity 221 opened on the inner wall of the spray gun 121. A piston block 222 is slidably connected to the inner wall of the flow-dividing cavity 221, and a sealing ring 2 is fixedly connected to the outer wall of the piston block 222. During the continuous spraying of slurry into the mine soil, as the diameter of nozzle 122 gradually decreases, if fibers and large soil clods in the slurry form a bridging structure within nozzle 122, it will cause nozzle 122 to gradually become clogged. When nozzle 122 is clogged, the amount of slurry sprayed will be greatly reduced, and the slurry in spray gun 121 will concentrate in the diversion chamber 221. The pressure of the slurry will push piston block 222 to move.

[0030] The unblocking assembly 31 includes a spring ring 311 that is slidably connected to the inner wall of the spray gun 121. A unblocking rod 313 is fixedly connected to the side of the spring ring 311 away from the piston block 222. A fixing ring 312 is fixedly connected to the inner wall of the spray gun 121. A sealing ring is fixedly connected to the inner wall of the fixed ring 312. The inner wall of the sealing ring is slidably connected to the outer wall of the unblocking rod 313. The side of the spring ring 311 away from the fixed ring 312 is fixedly connected to the side of the piston block 222 close to the fixed ring 312. When the piston block 222 moves, it will drive the spring ring 311 to move, causing the spring of the spring ring 311 to be compressed and accumulate rebound force. The movement of the spring ring 311 will drive the unblocking rod 313 to move towards the nozzle 122. When the unblocking rod 313 comes into contact with the accumulated fiber and soil particles, it will push such blockages out of the nozzle 122, thus unblocking the nozzle 122. At this time, the blockage in the nozzle 122 is cleared, and the slurry can be quickly sprayed out from the nozzle 122. The pressure on the piston block 222 also decreases, and the rebound force of the spring ring 311 is released and pushes the piston block 222 back to its original position. The piston block 222 is moved by the slurry pressure, which in turn drives the unblocking rod 313 to unblock the nozzle 122, realizing automatic unblocking. This solves the problem of needing to stop the machine to clean the nozzle 122 after it is blocked, allowing the nozzle 122 to spray continuously and stably, improving the work efficiency.

[0031] The cleaning component 32 includes an annular scraper 321 that is slidably connected to the inner wall of the diversion chamber 221, and a connecting rod 322 is fixedly connected to the side of the annular scraper 321 near the piston block 222. The outer wall of the connecting rod 322 is rotatably connected to the inner wall of the piston block 222. A sealing ring is fixedly connected to the inner wall of the piston block 222, and the inner wall of the sealing ring is rotatably connected to the outer wall of the connecting rod 322. The outer wall of the connecting rod 322 is provided with a spiral groove 323, and the top of the inner wall of the diversion cavity 221 is fixedly connected with a ball rod 324, and the bottom of the ball rod 324 is slidably connected to the inner wall of the spiral groove 323. The annular scraper 321 can also rotate while sliding on the inner wall of the diversion cavity 221. When the piston block 222 moves, it will push the connecting rod 322 to move synchronously. The connecting rod 322 will drive the annular scraper 321 to move together. Because the ball rod 324 limits the spiral groove 323, the ball rod 324 will generate a lateral thrust on the groove wall of the spiral groove 323 during the movement of the connecting rod 322, pushing the connecting rod 322 to rotate. This allows the connecting rod 322 to rotate while sliding, and the connecting rod 322 will drive the annular scraper 321 to rotate. When the piston block 222 returns to its original position, it pushes the annular scraper 321 to return as well, and drives the connecting rod 322 to reset. During the return process of the connecting rod 322, the ball bearing 324 will cause the connecting rod 322 to rotate again, which in turn drives the annular scraper 321 to rotate. When the annular scraper 321 rotates, its outer wall will scrape off the slurry adhering to the inner wall of the diversion cavity 221, such as... Figure 9 The position of I in the middle is shown; Simultaneously, during the sliding process of the annular scraper 321, its inclined surface can again scrape away the slurry on the inner wall of the diversion cavity 221, such as... Figure 9 As shown in the position of H, the above-mentioned double scraping action can fully remove the slurry adhering to the inner wall of the diversion chamber 221, significantly reduce the amount of slurry adhering to the outer wall of the piston block 222 during the return process, and effectively prevent excessive slurry from adhering to the outer wall of the piston block 222 during the return process. If the slurry adhering to the outer wall of the piston block 222 gradually solidifies during the continuous spraying of the nozzle 122, it will increase the sliding resistance of the piston block 222, affect the pushing effect of the subsequent slurry pressure on the piston block 222, and thus reduce the cleaning efficiency when the nozzle 122 is blocked again. By enlarging the nozzle diameter at the spray gun 121 on the right side of the guide block 213, such as... Figure 5 As shown in the position of G, when the slurry flows to this expansion area, the flow area increases accordingly due to the increased pipe diameter of the spray gun 121, and the slurry flow velocity decreases accordingly. This reduces the direct impact of the slurry and the grass seeds inside on the guide block 213, effectively preventing the grass seeds in the slurry from rapidly impacting the guide block 213 when they come into contact with it, which could easily cause damage to the grass seeds. This protects the germination activity of the grass seeds, ensures the normal emergence and growth of subsequent vegetation, and thus guarantees the overall effect of mine soil remediation.

[0032] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0033] A specific application of this embodiment is as follows: When using this invention, the operator first connects the spraying vehicle 13 to an external tractor, and the external tractor drives the spraying vehicle 13 to move. When it is necessary to repair the mine soil, the operator adds a mixture of grass seeds, fiber, soil and adhesive with water into the spraying vehicle 13 and mixes it into a slurry. Then, the water pump 14 is started to draw the slurry in the spraying vehicle 13 into the liquid inlet pipe 112, and then into the water pump 14 through the liquid inlet pipe 112. The slurry is fed into the delivery pipe 111 through the water pump 14, and then enters the spray gun 121 through the delivery pipe 111. After the slurry comes into contact with the guide block 213 in the spray gun 121, it will be divided into two streams by the guide block 213, which will enter the first guide pipe 211 and the second guide pipe 212 respectively. The slurry will flow back into the spray gun 121 along the first guide pipe 211 and the second guide pipe 212, and finally be sprayed out towards the mine soil through the nozzle 122. During the process of spraying the slurry through the nozzle 122, the operator can adjust the spray angle by rotating the spray gun 121. During the continuous spraying of slurry into the mine soil, as the diameter of the nozzle 122 gradually decreases, if the fibers and large soil clods in the slurry form a bridging structure within the nozzle 122, the nozzle 122 will gradually become clogged. When the nozzle 122 is clogged, the amount of slurry sprayed will be greatly reduced, and the slurry in the spray gun 121 will concentrate into the diversion chamber 221. The pressure of the slurry will push the piston block 222 to move, which will drive the spring ring 311 to move, causing the spring of the spring ring 311 to be compressed and accumulate rebound force. The movement of the spring ring 311 will drive the unblocking rod 313 to move towards the nozzle 122. When the unblocking rod 313 comes into contact with the accumulated fibers and soil particles, it will push such blockages out of the nozzle 122, thus unblocking the nozzle 122. At this time, the blockage in the nozzle 122 is cleared, and the slurry can be quickly sprayed out from the nozzle 122. The pressure on the piston block 222 also decreases. The rebound force of the spring ring 311 is released and pushes the piston block 222 back to its original position. The piston block 222 is moved by the slurry pressure, which in turn drives the unblocking rod 313 to unblock the nozzle 122, realizing automatic unblocking. This solves the problem of needing to stop the machine to clean the nozzle 122 after it is blocked, so that the nozzle 122 can spray continuously and stably, improving the work efficiency. Secondly, when the piston block 222 moves, it will push the connecting rod 322 to move synchronously. The connecting rod 322 will drive the annular scraper 321 to move together. Because the ball rod 324 limits the spiral groove 323, during the movement of the connecting rod 322, the ball rod 324 will generate a lateral thrust on the groove wall of the spiral groove 323, pushing the connecting rod 322 to rotate, so that the connecting rod 322 can rotate while sliding. The connecting rod 322 will then drive the annular scraper 321 to rotate. When the piston block 222 returns to its original position, it pushes the annular scraper 321 to return as well, and drives the connecting rod 322 to reset. During the return process of the connecting rod 322, the ball bearing 324 will cause the connecting rod 322 to rotate again, which in turn drives the annular scraper 321 to rotate. When the annular scraper 321 rotates, its outer wall will scrape off the slurry adhering to the inner wall of the diversion cavity 221, such as... Figure 9 The position of I in the middle is shown; Simultaneously, during the sliding process of the annular scraper 321, its inclined surface can again scrape away the slurry on the inner wall of the diversion cavity 221, such as... Figure 9 As shown in the position of H, the above-mentioned double scraping action can fully remove the slurry adhering to the inner wall of the diversion chamber 221, significantly reduce the amount of slurry adhering to the outer wall of the piston block 222 during the return process, and effectively prevent excessive slurry from adhering to the outer wall of the piston block 222 during the return process. If the slurry adhering to the outer wall of the piston block 222 gradually solidifies during the continuous spraying of the nozzle 122, it will increase the sliding resistance of the piston block 222, affect the pushing effect of the subsequent slurry pressure on the piston block 222, and thus reduce the cleaning efficiency when the nozzle 122 is blocked again. Furthermore, the slurry, after being diverted by the guide block 213, enters the first guide pipe 211 and the second guide pipe 212. Because their inner diameters are much smaller than the inner diameter of the spray gun 121, the slurry's flow velocity will increase significantly. When the slurry flows back into the spray gun 121 along the first guide pipe 211, it will impact the slurry inside the spray gun 121, causing turbulence and dispersing the fibers that are about to overlap. This disrupts the bridging structure formed by the intertwining and overlapping of fibers and clay clumps, reducing the amount of solid matter agglomerated at the nozzle 122. Additionally, the slurry flowing out of the second guide pipe 212 will impact the inner wall of the nozzle 122 outlet, such as... Figure 4As shown, a lateral impact force is applied to the fiber bridging structure overlapping at the outlet of the nozzle 122, which facilitates the impact of the newly formed bridging structure to be ejected from the nozzle 122, continuously cleaning the areas of the nozzle 122 where accumulation is likely to occur, and preventing the nozzle 122 from becoming clogged at the source. Additionally, by enlarging the nozzle diameter at the spray gun 121 on the right side of the guide block 213, such as... Figure 5 As shown in the position of G, when the slurry flows to this expansion area, the flow area increases accordingly due to the increased pipe diameter of the spray gun 121, and the slurry flow velocity decreases accordingly. This reduces the direct impact of the slurry and the grass seeds inside on the guide block 213, effectively preventing the grass seeds in the slurry from rapidly impacting the guide block 213 when they come into contact with it, which could easily cause damage to the grass seeds. This protects the germination activity of the grass seeds, ensures the normal emergence and growth of subsequent vegetation, and thus guarantees the overall effect of mine soil remediation. Meanwhile, after the slurry is diverted into the small-diameter guide pipe 211 and guide pipe 212, the slurry flow rate will increase again, thereby ensuring that the slurry has sufficient injection speed when it is ejected from the nozzle 122.
