Description

Technical Field

[0001] This invention belongs to the field of track construction technology and relates to a coating spraying device, particularly a coating spraying device for waterproofing construction of high-speed railway tracks to prevent outward diffusion. Background Technology

[0002] High-speed rail lines mainly consist of roadbeds, bridges, and tunnels. After the railway line construction is completed, a waterproof layer needs to be installed on its base surface. The waterproof material is mainly used to prevent rainwater, groundwater, industrial and domestic water supply and drainage, corrosive liquids, and moisture and vapor in the air from penetrating the structure. It can effectively prevent water from seeping into the base structure, slow down the aging of concrete and the corrosion of steel bars in the base surface, thereby improving the durability of the structure. Therefore, waterproofing is an important part of high-speed rail engineering. At present, waterproofing construction is carried out by manually laying rolls of material. When laying the rolls, a blowtorch is used to heat the material until the asphalt melts before laying and rolling it into shape.

[0003] After the waterproof membrane is laid, waterproof coating needs to be sprayed at the inside corners of the waterproof layer. Before spraying, first heat the coating to the predetermined temperature, then start the dedicated spraying equipment and check that the spray gun and nozzle are functioning properly. Perform a test spray; once normal operation is achieved, proceed with large-area spraying. During large-area spraying, adjust the distance between the nozzle and the substrate, as well as the spraying equipment pressure. Spray half the coating onto the bottom of the waterproof membrane and half onto the concrete substrate surface, ensuring a uniform coating thickness of at least 1.5mm. The width of each sprayed area should be 20mm wider than the membrane width to ensure full adhesion at the overlap edges.

[0004] Existing spraying equipment typically involves manual application of waterproofing materials to corners using handheld spray guns. This method not only makes it difficult to ensure uniformity of the spray, but also results in high workload. Furthermore, because the sprayed waterproofing material is in the form of a water mist, it easily spreads beyond the areas to be sprayed, and a large amount of waterproofing material escapes into the air, causing environmental pollution. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a coating spraying device for waterproofing construction of high-speed railway tracks that prevents material scattering. The technical problem this invention aims to solve is: how to prevent material scattering during waterproofing material spraying operations.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A coating spraying device for waterproofing construction of high-speed railway tracks, comprising a machine body, a storage tank fixed on the machine body, a stirring mechanism on the storage tank, a first electric telescopic rod fixed to the outside of the storage tank, a connecting seat fixed to the telescopic end of the first electric telescopic rod, a second electric telescopic rod fixed to the lower side of the connecting seat, an L-shaped seat fixed to the lower end of the second electric telescopic rod, baffles fixed to the front and rear sides of the L-shaped seat, a spraying assembly installed inside the L-shaped seat, the spraying assembly communicating with the interior of the storage tank, an air supply chamber opened in the side wall of the L-shaped seat, the air supply chamber being connected to the stirring mechanism through the air supply assembly, and air outlets opened at the right end and the lower end of the L-shaped seat, the air outlets communicating with the air supply chamber, and a reducing section provided at the connection between the air outlet and the air supply chamber.

[0008] The working principle of this invention is as follows: During operation, the waterproof coating is added to the storage tank, heated and stirred evenly using a stirring mechanism. Then, the machine body is pushed to the position where spraying is required, so that the left and lower ends of the L-shaped seat abut against the edge of the waterproof membrane and the surface of the concrete substrate, respectively. This creates a relatively sealed space between the L-shaped seat, the edge of the waterproof membrane, and the concrete substrate. Simultaneously, the air supply mechanism and the spraying mechanism are activated for spraying. The gap between the L-shaped seat and the edge of the waterproof membrane and the concrete substrate forms an air curtain, preventing the waterproof coating from spreading outside the device. The distance between the spraying components and the edge of the waterproof membrane and the concrete substrate can be controlled using the L-shaped seat, resulting in good spray uniformity and reduced work difficulty.

[0009] The stirring mechanism includes a drive column fixed inside a storage tank. A hot air blower is fixed at the upper end of the storage tank. An air supply channel is opened inside the drive column, and the air outlet of the hot air blower is connected to the air supply channel. A rotating cylinder is rotatably fitted around the outer periphery of the drive column. Several stirring rods are fixed on the outer side of the rotating cylinder. A heat conduction cavity is opened inside the stirring rod and is connected to the interior of the storage tank. Several rows of annularly distributed oblique flow nozzles are opened inside the drive column. The air supply channel is connected to the interior of the rotating cylinder through the oblique flow nozzles. Several rows of annularly distributed arc-shaped inclined plates are fixed on the inner periphery of the rotating cylinder, and the oblique flow nozzles correspond to the arc-shaped inclined plates.

[0010] The air delivery assembly includes an air delivery pipe, which is connected to the drive column, and the other end of the air delivery pipe is connected to the air delivery chamber through a first flexible hose.

[0011] With the above structure, during operation, the hot air blower is turned on, and the hot air is delivered into the rotating drum through the air supply channel and the oblique flow nozzle, and then transferred to the heat conduction chamber. The rotating drum and stirring rod heat the waterproof coating. Simultaneously, when the oblique flow nozzle exits, the hot air is sprayed onto the curved inclined plate, and the air force drives the rotating drum to rotate, causing the stirring rod to mix the waterproof material. Then, the hot air enters the air supply chamber through the air supply pipe, making the air curtain ejected from the outlet hot air. This not only prevents material from escaping but also allows for rapid drying of the sprayed waterproof material. This prevents the waterproof coating from flowing after being sprayed onto the edges of the waterproof membrane and the concrete substrate, improving the spraying quality and reducing the amount of waterproof material released into the air, thus reducing environmental pollution. This structure, using only a hot air blower, can achieve mixing, heating, preventing escaping, and drying functions, reducing equipment operating costs and maximizing the utilization of hot air, resulting in energy saving and environmental protection.

[0012] The spraying assembly protects the arc-shaped box, which is fixed inside the L-shaped base. Several spray nozzles are evenly distributed on the arc-shaped box. A feeding pump is fixed inside the storage tank, and a feeding pipe is fixed on the feeding pump. The feeding pipe is connected to the arc-shaped box through a second flexible hose.

[0013] With the above structure, when the feeding pump is turned on during operation, the feeding pump delivers the waterproof material in the discharge pipe into the arc-shaped box through the feeding pipe and the second flexible hose, and then sprays it out through the nozzle. With the help of the L-shaped seat, automated spraying operation is achieved.

[0014] The L-shaped seat has sliding cavities at both the right and lower ends. A spring is fixed inside the sliding cavity, and a sliding plate is fixed at the other end of the spring. The sliding plate is slidably connected to the sliding cavity. A baffle plate is fixed on the lower side of the sliding plate, and the other end of the baffle plate extends out of the sliding cavity. The baffle plate is located on the side of the air outlet away from the spraying component.

[0015] With the above structure, during operation, the baffle plate can come into contact with the edges of the waterproof membrane and the concrete substrate. In conjunction with the spring, the machine body can adapt to the shaking caused by operation and road conditions when moving, preventing the L-shaped plate from colliding with the edges of the waterproof membrane and the concrete substrate due to machine shaking. This protects both the device and the edges of the waterproof membrane and the concrete substrate. Furthermore, since the baffle plate is located on the side of the air outlet away from the spraying components, the possibility of waterproof coating adhering to the baffle plate is greatly reduced.

[0016] The end of the baffle plate extending out of the sliding cavity is equipped with several ball bearings.

[0017] By adopting the above structure, during operation, the sliding friction between the baffle plate and the edges of the waterproof membrane and the concrete substrate can be converted into rolling friction, which further improves the protection of the device, the edges of the waterproof membrane, and the concrete substrate. In addition, during operation, the ball bearings can also adhere tightly to the waterproof membrane and not detach, thereby playing a certain guiding role for the machine body and reducing the probability that the machine body's movement path is not straight, which affects the spraying quality.

[0018] The baffle plate has an arc-shaped guide section on the side near the spraying assembly, and there is a gap between the vertical surface of the end of the arc-shaped guide section and the side of the air outlet near the spraying assembly.

[0019] With the above structure, during operation, part of the air ejected from the air outlet forms an air curtain, while the other part is sprayed onto the arc-shaped guide section. The arc-shaped guide section is used to change the direction, so that the hot air can diffuse into the L-shaped seat, improving the drying quality.

[0020] A lifting seat is slidably connected to the right end of the machine body. An L-shaped pusher plate is fixed to the right end of the lifting seat. A scraper plate is fixed to the lower end of the L-shaped pusher plate. A storage box is fixed to the upper side of the lifting plate. A support plate is fixed to the storage box. The support plate is connected to the machine body through a third electric telescopic rod.

[0021] Using the above mechanism, during operation, it is necessary to maintain a certain distance between the machine body and the waterproof membrane during track construction. However, due to cost and structural design considerations, the concrete base surface is not very wide, which may cause the machine body to move on the soil surface. Since the soil surface cannot be completely flat, this structure is designed so that when the machine body moves on the soil surface, the shovel plate and L-shaped pusher plate can be used to flatten the road surface along the machine body's movement path, thereby improving the stability of the machine body's movement.

[0022] The storage box is equipped with a screw feeder, and a material collection port is opened on the shovel plate. The feed pipe of the screw feeder is located inside the material collection port. A filling cavity is opened on the lower side of the lifting seat. A discharge pipe is fixed at the lower end of the storage box. The lower outer side of the discharge pipe extends into the filling cavity and is fitted with a counterweight pipe. A slider is fixed on the counterweight pipe. A sliding groove is opened on the outer side of the discharge pipe. The slider is slidably connected to the sliding groove.

[0023] With the above structure, when the ground is leveled, some soil will enter the collection port. Then, the soil will be sent to the storage box by the screw feeding mechanism. During operation, the counterweight block always keeps in contact with the ground. When a pit appears on the ground, the soil will enter the pit through the discharge pipe to fill the pit and compact it with the counterweight block to further improve the flatness of the ground.

[0024] An overflow pipe is fixed to the upper part of the storage box, and a discharge pipe is fixed to the other end of the overflow pipe. A dust cover is fitted to the lower end of the discharge pipe. A limit block is fixed to the end of the discharge pipe inside the dust cover. A first V-shaped guide is provided on the upper half of the side of the dust cover facing the direction of movement of the machine body, and a second V-shaped guide is provided on the lower half of the side of the dust cover facing the direction of movement of the machine body. The lower end of the second V-shaped guide is inclined toward the outlet of the dust cover.

[0025] With the above structure, when the soil in the storage tank exceeds a certain amount during operation, it can be discharged through the overflow pipe to prevent the soil in the storage tank from affecting the leveling effect on the ground. When the soil falls, the dust cover is close to the ground, which can prevent the dust generated by the soil falling to the ground from escaping, thereby reducing environmental pollution. The first V-shaped guide and the second V-shaped guide can not only push the debris on the ground where the dust cover is located to both sides, but also make the dust cover rise when it encounters more solid debris, thereby protecting the dust cover. It is highly practical.

[0026] Compared with existing technologies, this anti-spreading coating spraying equipment for waterproofing construction of high-speed railway tracks has the following advantages:

[0027] 1. During operation, the waterproof coating is added to the storage tank, heated and stirred evenly using the stirring mechanism. Then, the machine body is pushed to the position to be sprayed, so that the left and lower ends of the L-shaped seat abut against the edge of the waterproof membrane and the surface of the concrete substrate, respectively. This creates a relatively sealed space between the L-shaped seat, the edge of the waterproof membrane, and the concrete substrate. Then, the air supply mechanism and the spraying mechanism are turned on simultaneously to spray the coating. The gap between the L-shaped seat and the edge of the waterproof membrane and the concrete substrate forms an air curtain, preventing the waterproof coating from spreading outside the device. The L-shaped seat can also be used to control the distance between the spraying components and the edge of the waterproof membrane and the concrete substrate, resulting in good spray uniformity and reducing the difficulty of the operation.

[0028] 2. The mixing mechanism is designed so that, during operation, the hot air blower is turned on, and hot air is delivered into the rotating drum through the air supply channel and the oblique flow nozzle, and then transferred to the heat conduction chamber. This heats the waterproof coating using the rotating drum and the mixing rod. Simultaneously, when the oblique flow nozzle exits, the hot air is sprayed onto the curved inclined plate, and the airflow drives the rotating drum to rotate, causing the mixing rod to mix the waterproof material. The hot air then enters the air supply chamber through the air supply pipe, resulting in a hot air curtain at the outlet. This not only prevents material from escaping but also allows for rapid drying of the sprayed waterproof material. This prevents the waterproof coating from flowing after being sprayed onto the edges of the waterproof membrane and the concrete substrate, improving the spraying quality and reducing the amount of waterproof material released into the air, thus reducing environmental pollution. This structure, using only a hot air blower, achieves mixing, heating, preventing escaping, and drying functions, reducing equipment operating costs and maximizing the utilization of hot air, resulting in energy conservation and environmental protection.

[0029] 3. The baffle plate's structure allows it to contact the edges of the waterproof membrane and the concrete substrate. Combined with springs, this design allows the machine to adapt to swaying caused by operation and road conditions during movement, preventing the L-shaped plate from colliding with the edges of the waterproof membrane and the concrete substrate due to machine movement. This protects both the device and the edges of the waterproof membrane and the concrete substrate. Furthermore, since the baffle plate is located on the side of the air outlet away from the spraying components, it significantly reduces the possibility of waterproof coating adhering to the baffle plate.

[0030] 4. The arc-shaped air guide section allows part of the air ejected from the air outlet to form an air curtain, while the other part is sprayed onto the arc-shaped air guide section. By using the arc-shaped air guide section to change direction, the hot air can diffuse into the L-shaped seat, improving the drying quality.

[0031] 5. The installation of shovel plates and other structures is necessary because during track construction, it is required to maintain a certain distance between the machine body and the waterproof membrane. However, due to cost and structural design considerations, the concrete base surface is not very wide, which may cause the machine body to move on the soil surface. Since the soil surface cannot be completely flat, this structure is designed so that when the machine body moves on the soil surface, the shovel plates and L-shaped pusher plates can be used to flatten the road surface along the machine body's movement path, thereby improving the stability of the machine body's movement.

Detailed Implementation

[0043] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0044] like Figures 1-10As shown, this high-speed railway track waterproofing construction coating spraying equipment includes a body 1, a storage tank 2 fixed on the body 1, a stirring mechanism on the storage tank 2, a first electric telescopic rod 16 fixed on the outside of the storage tank 2, a connecting seat 17 fixed at the telescopic end of the first electric telescopic rod 16, a second electric telescopic rod 18 fixed on the lower side of the connecting seat 17, an L-shaped seat 22 fixed at the lower end of the second electric telescopic rod 18, baffles fixed on both the front and rear sides of the L-shaped seat 22, a spraying component installed inside the L-shaped seat 22, the spraying component communicating with the interior of the storage tank 2, an air supply chamber 25 opened in the side wall of the L-shaped seat 22, the air supply chamber being connected to the stirring mechanism through the air supply component, an air outlet 26 opened at the right end and the lower end of the L-shaped seat 22, the air outlet 26 communicating with the air supply chamber 25, and a variable diameter part being provided at the connection between the air outlet 26 and the air supply chamber 25.

[0045] During operation, the waterproof coating is added to the storage tank 2, heated and stirred evenly using the stirring mechanism. Then, the machine body 1 is pushed to the position to be sprayed, so that the left and lower ends of the L-shaped seat 22 abut against the edge of the waterproof membrane and the surface of the concrete substrate, respectively. This creates a relatively sealed space between the L-shaped seat 22, the edge of the waterproof membrane, and the concrete substrate. Then, the air supply mechanism and the spraying mechanism are turned on simultaneously for spraying. The gap between the L-shaped seat 22 and the edge of the waterproof membrane and the concrete substrate forms an air curtain, preventing the waterproof coating from spreading outside the device. The distance between the spraying component and the edge of the waterproof membrane and the concrete substrate can be controlled using the L-shaped seat 22, resulting in good spray uniformity and reducing the difficulty of the operation.

[0046] The stirring mechanism includes a drive column 13, which is fixed inside the storage tank 2. A hot air blower 12 is fixed at the upper end of the storage tank 2. An air supply channel 42 is opened inside the drive column 13. The air outlet of the hot air blower 12 is connected to the air supply channel 42. A rotating cylinder 14 is rotatably sleeved on the outer periphery of the drive column 13. Several stirring rods 15 are fixed on the outer side of the rotating cylinder 14. A heat conduction cavity 45 is opened inside the stirring rod 15. The heat conduction cavity 45 is connected to the interior of the storage tank 2. Several rows of annularly distributed oblique flow nozzles 44 are opened inside the drive column 13. The air supply channel 42 is connected to the interior of the rotating cylinder 14 through the oblique flow nozzles 44. Several rows of annularly distributed arc-shaped inclined plates 43 are fixed on the inner periphery of the rotating cylinder 14. The oblique flow nozzles 44 correspond to the arc-shaped inclined plates 43.

[0047] The air supply assembly includes an air supply pipe 19, which is connected to the drive column 13. The other end of the air supply pipe 19 is connected to the air supply chamber 25 through a first flexible hose.

[0048] With the above structure, during operation, the hot air blower 12 is turned on. The hot air blower 12 sends hot air through the air supply channel 42 and the oblique flow nozzle 44 into the rotating cylinder 14, and then transfers it to the heat conduction chamber 45. This allows the rotating cylinder 14 and the stirring rod 15 to heat the waterproof coating. Simultaneously, when the oblique flow nozzle 44 emits air, the hot air is sprayed onto the arc-shaped inclined plate 43. Under the action of the wind, the rotating cylinder 14 rotates, causing the stirring rod 15 to stir and mix the waterproof material. Then, the hot air enters the air supply chamber 25 through the air supply pipe 19, causing the air outlet... The air curtain 26 sprays hot air, which not only prevents the material from escaping, but also uses the hot air to quickly dry the sprayed waterproof material. This prevents the waterproof coating from flowing after being sprayed on the edges of the waterproof membrane and the concrete substrate, improving the quality of the spraying. It also reduces the amount of waterproof material escaping into the air, thus reducing environmental pollution. With this structure, the hot air blower 12 alone can achieve functions such as stirring, heating, preventing escaping, and drying. This not only reduces the operating cost of the equipment, but also maximizes the utilization of hot air, making it energy-saving and environmentally friendly.

[0049] The spraying assembly protects the arc-shaped box 23, which is fixed inside the L-shaped base 22. Several spray nozzles 24 are evenly distributed on the arc-shaped box 23. A feeding pump 20 is fixed inside the storage tank 2, and a feeding pipe 21 is fixed on the feeding pump 20. The feeding pipe 21 is connected to the arc-shaped box 23 through a second flexible hose.

[0050] With the above structure, when the feed pump 20 is turned on during operation, the feed pump 20 sends the waterproof material in the discharge pipe 37 into the arc-shaped box through the feed pipe 21 and the second hose, and sprays it out through the nozzle 24. With the help of the L-shaped seat 22, the automated spraying operation is realized.

[0051] The right and lower ends of the L-shaped base 22 are provided with sliding cavities 27. A spring 28 is fixed inside the sliding cavity 27. A sliding plate 29 is fixed to the other end of the spring 28. The sliding plate 29 is slidably connected to the sliding cavity 27. A baffle plate 30 is fixed to the lower side of the sliding plate 29. The other end of the baffle plate 30 extends out of the sliding cavity 27. The baffle plate 30 is located on the side of the air outlet 26 away from the spraying component.

[0052] With the above structure, during operation, the baffle plate 30 can come into contact with the edges of the waterproof membrane and the concrete substrate. In conjunction with the spring 28, the machine body 1 can adapt to the shaking caused by operation and road conditions when moving, preventing the L-shaped plate from colliding with the edges of the waterproof membrane and the concrete substrate due to the shaking of the machine body 1. This protects the device and the edges of the waterproof membrane and the concrete substrate. Furthermore, since the baffle plate 30 is located on the side of the air outlet 26 away from the spraying components, the possibility of waterproof coating adhering to the baffle plate 30 can be greatly reduced.

[0053] A number of ball bearings 31 are provided at one end of the baffle plate 30 that extends out of the slide cavity 27.

[0054] With the above structure, during operation, the sliding friction between the baffle plate 30 and the edges of the waterproof membrane and the concrete substrate can be converted into rolling friction, which further improves the protection of the device, the edges of the waterproof membrane, and the concrete substrate. In addition, during operation, the ball bearings 31 can also be kept in close contact with the waterproof membrane and not detach, thereby playing a certain guiding role for the machine body 1 and reducing the probability that the movement path of the machine body 1 is not straight and affects the spraying quality.

[0055] The baffle plate 30 has an arc-shaped guide section on the side near the spraying component, and there is a gap between the vertical surface of the end of the arc-shaped guide section and the side of the air outlet 26 near the spraying component.

[0056] With the above structure, during operation, part of the air ejected from the air outlet 26 forms an air curtain, while the other part is sprayed onto the arc-shaped guide section. The arc-shaped guide section is used to change the direction, so that the hot air can diffuse into the L-shaped seat 22, thereby improving the drying quality.

[0057] A lifting seat 6 is slidably connected to the right end of the machine body 1. An L-shaped pusher plate 10 is fixed to the right end of the lifting seat 6. A scraper plate 32 is fixed to the lower end of the L-shaped pusher plate 10. A storage box 3 is fixed to the upper side of the lifting plate. A support plate 4 is fixed to the storage box 3. The support plate 4 is connected to the machine body 1 through a third electric telescopic rod 5.

[0058] Using the above mechanism, during operation, it is necessary to maintain a certain distance between the machine body 1 and the waterproof membrane during track construction. However, due to cost and structural design reasons, the concrete base surface is not very wide, which means that the machine body 1 may move on the soil surface when moving. The soil surface cannot be completely guaranteed to be flat. Therefore, this structure is designed so that when the machine body 1 moves on the soil surface, the shovel plate 32 and the L-shaped pusher plate 10 can be used to flatten the road surface along the movement path of the machine body 1, thereby improving the stability of the machine body 1's movement.

[0059] A screw feeder 11 is installed on the storage box 3. A material collection port 33 is opened on the shovel plate 32. The feed pipe of the screw feeder 11 is located in the material collection port 33. A filling cavity 7 is opened on the lower side of the lifting seat 6. A discharge pipe 9 is fixed at the lower end of the storage box 3. The lower end of the discharge pipe 9 extends into the filling cavity 7 and is fitted with a counterweight pipe 8. A slider 35 is fixed on the counterweight pipe 8. A sliding groove 34 is opened on the outer side of the discharge pipe 9. The slider 35 is slidably connected to the sliding groove 34.

[0060] With the above structure, when the ground is leveled, some soil will enter the collection port 33. Then, the screw feeder 11 will send the soil to the storage box 3. During operation, the counterweight block will always be in contact with the ground. When a pit appears on the ground, the soil will enter the pit through the discharge pipe 9 to fill the pit and compact it with the counterweight block to further improve the flatness of the ground.

[0061] An overflow pipe 36 is fixed to the upper part of the storage box 3, and a discharge pipe 37 is fixed to the other end of the overflow pipe 36. A dust cover 38 is fitted to the lower end of the discharge pipe 37. A limit block 39 is fixed to one end of the discharge pipe 37 inside the dust cover 38. A first V-shaped guide part 40 is provided on the upper half of the side of the dust cover 38 facing the moving direction of the machine body 1, and a second V-shaped guide part 41 is provided on the lower half of the side of the dust cover 38 facing the moving direction of the machine body 1. The lower end of the second V-shaped guide part 41 is inclined toward the outlet of the dust cover 38.

[0062] With the above structure, when the soil in the storage tank 3 exceeds a certain amount during operation, it can be discharged through the overflow pipe 36 to prevent the soil in the storage tank 3 from being full and affecting the leveling effect on the ground. When the soil falls, the dust cover 38 is close to the ground to prevent the dust generated by the soil falling to the ground from escaping, thereby reducing environmental pollution. The first V-shaped guide part 40 and the second V-shaped guide part 41 can not only push the debris on the ground where the dust cover 38 is located to both sides, but also make the dust cover 38 rise when it encounters relatively firm debris, thereby protecting the dust cover 38. It is highly practical.

[0063] The working principle of this invention is as follows: During operation, waterproof coating is added to the storage tank 2, and the hot air blower 12 is turned on. The hot air blower 12 sends hot air through the air supply channel 42 and the oblique flow nozzle 44 into the rotating drum 14, and then transfers it to the heat conduction chamber 45. Thus, the rotating drum 14 and the stirring rod 15 heat the waterproof coating. At the same time, when the oblique flow nozzle 44 emits air, the hot air is sprayed onto the arc-shaped inclined plate 43. Under the action of the wind, the rotating drum 14 can be rotated, thereby causing the stirring rod 15 to stir and mix the waterproof material. Then, the machine body 1 is pushed to the position where spraying is required. This arrangement causes the two baffles 30 to abut against the edges of the waterproof membrane and the surface of the concrete substrate, respectively, creating a relatively sealed space between the L-shaped seat 22, the edges of the waterproof membrane, and the concrete substrate. Hot air then enters the air supply chamber 25 through the air supply pipe 19, resulting in a hot air curtain ejected from the air outlet 26. This prevents the waterproof coating from dissipating outside the device. Furthermore, part of the air ejected from the air outlet 26 forms an air curtain, while the other part is sprayed onto the arc-shaped guide section, which redirects the hot air, allowing it to diffuse into the L-shaped seat 22 and improving drying efficiency. The quality of the spraying is improved, and the distance between the spraying components and the edges of the waterproof membrane and the concrete base can be controlled by the L-shaped seat 22, resulting in good spraying uniformity and reducing the difficulty of the work. When the machine body 1 moves on the soil surface, the road surface along the movement path of the machine body 1 can be leveled by using the shovel plate 32 and the L-shaped pusher plate 10. Some soil will enter the collection port 33, and then the screw feeder 11 will send the soil to the storage box 3. During operation, the counterweight block always keeps in contact with the ground. When a pit appears on the ground, the soil will enter the pit through the discharge pipe 9 to fill the pit. When the soil in the storage tank 3 exceeds a certain amount, it can be discharged through the overflow pipe 36 to prevent the soil in the storage tank 3 from being full and affecting the leveling effect on the ground. When the soil falls, the dust cover 38 is close to the ground to prevent the dust generated by the soil falling to the ground from escaping, thereby reducing environmental pollution. The first V-shaped guide part 40 and the second V-shaped guide part 41 can not only push the debris on the ground where the dust cover 38 is located to both sides, but also make the dust cover 38 rise when it encounters relatively firm debris, thereby protecting the dust cover 38. It is highly practical.

[0064] In summary, the design of structures such as the L-shaped seat 22 and the mixing mechanism enables the prevention of material spillage during the spraying of waterproof materials.
