Description

Technical Field

[0001] This invention relates to the field of spraying technology, specifically to a high-performance curing material spraying machine that integrates stirring and spraying. Background Technology

[0002] The integrated mixing and spraying high-performance curing material spraying machine is a mechanical device that combines mixing and spraying functions and is specifically designed for curing projects. It mixes curing materials in a specific ratio and then sprays the material at high speed onto the surface of the substrate requiring curing using high-pressure air or other power sources, forming a uniform curing layer and improving curing quality.

[0003] In the field of modern engineering maintenance, there are increasingly higher requirements for the efficiency and quality of maintenance materials. Traditional maintenance material spraying equipment often has many limitations. On the one hand, in the mixing stage, many devices cannot fully and evenly mix the materials, resulting in incomplete mixing and affecting the maintenance effect. On the other hand, the feeding and spraying functions are usually independent of each other, and cannot achieve integrated and efficient operation. During feeding, the negative pressure principle cannot be effectively utilized to quickly absorb the raw materials, resulting in slow feeding speed and potential material waste.

[0004] To address the aforementioned issues, there is an urgent need for a curing material spraying device that integrates efficient mixing, convenient feeding, and precise spraying. Therefore, we propose a high-performance curing material spraying machine that integrates mixing and spraying. Through its unique structural design and optimized workflow, it aims to improve the overall efficiency and quality of curing material application, meeting the high standards required for modern engineering maintenance. Summary of the Invention

[0005] The purpose of this invention is to provide a high-performance curing material spraying machine that integrates stirring and spraying, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-performance curing material spraying machine integrating stirring and spraying, comprising:

[0007] The frame has a stepped top, with a mixing device and a gas compression tank installed at two different heights on the frame. An injection pipe assembly is also installed on the side of the frame.

[0008] The injection pipe assembly also includes a shut-off valve integration, which includes the shut-off valve itself and four pipe end interfaces. Two pipe end interfaces are respectively provided at both ends of the shut-off valve itself. The two pipe end interfaces facing the first direction are respectively connected to the injection pipe and the material pipe. The other end of the material pipe is connected to the inside of the hopper, and the other end of the injection pipe is connected to the spray gun.

[0009] Further, the mixing device includes a base, a drive shaft rotatably mounted on the base, a mixing paddle fixedly connected to the top of the drive shaft, a housing also mounted on the base, the housing being annular, the mixing paddle rotating inside the housing, and a hopper fixed to the top of the housing, with a vibrator also mounted on the surface of the hopper.

[0010] Furthermore, a sealing plate is fixed on the base, and a surrounding plate, a distributor, a partition plate, and a connecting plate are arranged sequentially between the sealing plate and the stirring paddle. The surrounding plate is fixed to the top of the sealing plate, and the partition plate has several drainage holes equidistantly arranged around its own axis. A hole is also opened on the sealing plate, and the slurry is discharged from the hole on the sealing plate.

[0011] Furthermore, a distributor is rotatably mounted on the top of the enclosure. The distributor is disc-shaped and matches the inner wall of the housing. A partition is fixed on the top of the distributor, and the partition also has leakage holes that correspond to the leakage holes on the distributor.

[0012] Furthermore, the top of the partition plate is fixed with a connecting plate, which is fixed to the bottom of the housing. A slurry discharge port is provided on the connecting plate. The position of the slurry discharge port is offset from the projection position of the hole on the sealing plate. This offset design allows the slurry to be evenly distributed during the discharge process, avoiding direct impact on the sealing plate and causing local wear or blockage. It also helps to control the flow rate of the slurry and ensures the smooth progress of the slurry discharge process.

[0013] Furthermore, the distributor has a shaft hole in the middle that matches the surface of the drive shaft, and the cross-section of the drive shaft is non-circular.

[0014] Further, the shut-off valve itself has an air pipe connected to one of its pipe ends facing away from the first direction. The other end of the air pipe is connected to a gas compression tank, and the other pipe end can be used to connect a hose to the raw material.

[0015] Furthermore, valve one and valve two are respectively installed on the air pipe and the injection pipe.

[0016] In summary, in specific implementation, by closing valve two and opening valve one and the shut-off valve, a high-speed airflow is ejected from the gas compression tank. At this time, only valve two needs to be closed, and the gas in the pipe will quickly pass through the material pipe and form a negative pressure in the pipe. At this time, a suction effect can be formed by inserting one of the ports integrated with the shut-off valve into the raw material. The negative pressure in the pipe will draw the raw material in and transfer it to the hopper. After the mixing is completed, the material is discharged. The connection between the material pipe and the injection pipe, as well as the various interfaces of the shut-off valve, are all designed with high sealing performance to ensure that no leakage occurs during gas flow and material transfer.

[0017] During spray curing, opening valve two allows high-speed gas to flow through the spray pipe. The negative pressure created by this high-speed airflow not only draws the material from the hopper into the pipe but also forms a uniform spray stream at the spray gun. Adjusting the opening of valve two controls the spray pressure to accommodate different curing materials. This design ensures uniform distribution and strong adhesion of the curing material during spraying, thus improving the curing effect. The entire operation is simple and intuitive; feeding and spraying are achieved by controlling the opening and closing of the valves. Furthermore, the design of each component considers maintenance needs; for example, the mixing device is easy to disassemble and assemble, facilitating regular cleaning and maintenance, ensuring long-term stable operation of the equipment.

[0018] Furthermore, a steering wheel is installed at one end of the frame, and a handlebar is installed on the steering wheel to control its direction. An auxiliary wheel is installed at the other end of the frame to ensure the movement of the frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This integrated high-performance curing material spraying machine combines efficient mixing with precise spraying through the setup of a mixing device and spray pipe assembly. The unique mixing device design ensures thorough mixing and uniform distribution of materials, while the spray pipe assembly, in conjunction with a gas compression tank, creates a stable negative pressure to effectively draw in and spray curing materials. Furthermore, the spraying pressure can be adjusted to meet the spraying requirements of different materials, thereby improving the curing effect and satisfying the needs of efficient curing operations.

[0021] Meanwhile, the structural design of the equipment fully considers the ease of operation, practicality, and maintenance. The chassis has a stepped layout for the mixing device and gas compression tank, and is equipped with steering wheels and auxiliary wheels for easy and flexible movement in different work sites. The high sealing design of each connection ensures the reliability of gas and material transfer, prevents leakage, facilitates regular cleaning and maintenance, ensures long-term stable operation of the equipment, reduces maintenance costs and equipment failure rate, and extends service life.

[0027] 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.

[0028] It should be noted that in the description of this invention, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0031] like Figure 1 and Figure 2 As shown, the present invention provides a technical solution: a high-performance curing material spraying machine integrating mixing and spraying, including a frame 1, the top of the frame 1 is stepped, a mixing device 8 and a gas compression tank 5 are respectively installed at two height planes of the frame 1, and a spraying pipe assembly is also installed on one side of the frame 1.

[0032] like Figure 3As shown, the stirring device 8 includes a base 801, a drive shaft 809 is rotatably mounted on the base 801, a stirring paddle 808 for stirring is fixedly connected to the top of the drive shaft 809, a housing 807 is also mounted on the base 801, the housing 807 is annular, the stirring paddle 808 rotates inside the housing 807, and a hopper 6 is fixed to the top of the housing 807. A vibrator 7 is also mounted on the surface of the hopper 6. The vibrator 7 can reduce the adhesion of materials to the inner wall of the hopper 6.

[0033] In other words, this integrated mixing and spraying material spraying machine uses the mixing paddle 808 to mix materials and can feed materials at the hopper 6, achieving efficient mixing of materials.

[0034] like Figure 3 As shown, in order to ensure the smooth implementation of the above embodiments, it is necessary to understand that a sealing plate 802 is also fixed on the base 801. Between the sealing plate 802 and the stirring paddle 808, a surrounding plate 803, a distributor 804, a partition plate 805 and a connecting plate 806 are arranged in sequence. The surrounding plate 803 is fixed to the top of the sealing plate 802, and the partition plate 805 has a number of drainage holes equidistantly opened around its own axis. A hole is also opened on the sealing plate 802, and the slurry is discharged from the hole on the sealing plate 802.

[0035] like Figure 3 and Figure 4 As shown, it is also necessary to understand that a distributor 804 is rotatably installed on the top of the casing 803. The distributor 804 is disc-shaped and matches the inner wall of the casing 807. A partition 805 is fixed on the top of the distributor 804. The partition 805 is also provided with a leakage hole, which corresponds to the leakage hole on the distributor 804. A connecting plate 806 is fixed on the top of the partition 805. The connecting plate 806 is fixed to the bottom of the casing 807, and a slurry discharge port is opened on the connecting plate 806. The position of the slurry discharge port is offset from the projected position of the hole on the sealing plate 802. The offset design between the position of the slurry discharge port and the projected position of the hole on the sealing plate 802 allows the slurry to be evenly distributed during the discharge process, avoiding direct impact on the sealing plate 802 and causing local wear or blockage. It also helps to control the flow rate of the slurry and ensure the smooth progress of the slurry discharge process.

[0036] In other words, with the support of the above structure, after the raw material enters the hopper 6 and is stirred, it moves downward from the discharge port and is discharged through the hole on the self-sealing plate 802 between the partition plate 805, the connecting plate 806 and the surrounding plate 803. It should be noted that a shaft hole adapted to the surface of the drive shaft 809 is opened in the middle of the distributor 804, and the cross-section of the drive shaft 809 is non-circular. That is to say, the distributor 804 rotates with the rotation of the drive shaft 809.

[0037] like Figure 1 and Figure 2As shown, regarding the above embodiments, it is also necessary to know that the spray pipe assembly includes a feed pipe 9, which is connected to the inside of the hopper 6. The feed pipe 9 can be used to feed the raw materials of the curing material. Under the support of the above embodiments, the raw materials are stirred in the hopper 6 and move downward from the discharge port during the stirring process. However, in order to ensure the stirring efficiency and quality of the raw materials in the hopper 6, the stirring time of the raw materials in the hopper 6 must be guaranteed. Therefore, the hopper 6 and the sealing plate 802 cannot be a completely through channel. In this case, the distributor 804 rotates with the drive shaft 809. In this case, the slurry will stick to the inner wall of the distributor 804 under the action of centrifugal force, and the rotation of the distributor 804 changes the utilization of the gap. The slurry has more opportunities to squeeze and rearrange itself during the rotation process, resulting in a reduction or narrowing of the direct channel for the slurry to fall quickly, thereby slowing down the falling speed of the slurry and ensuring that the slurry is fully stirred in the hopper 6. A drive source for controlling the rotation of the drive shaft 809 is installed inside the frame 1.

[0038] like Figure 1 and Figure 2 As shown, to ensure the smooth implementation of the above embodiments, it is also necessary to know that the spray pipe assembly also includes a shut-off valve integration 10. The shut-off valve integration 10 includes the shut-off valve itself and four pipe end interfaces. Two pipe end interfaces are respectively provided at both ends of the shut-off valve itself. The two pipe end interfaces facing the first direction are respectively connected to the spray pipe 13 and the material pipe 9. The other end of the material pipe 9 is connected to the inside of the hopper 6. The other end of the spray pipe 13 is connected to the spray gun. The spray pipe 13 is provided with a branch pipe connected to the hole of the sealing plate 802. That is to say, the slurry will enter the spray pipe 13 and be sprayed out from the spray gun during the discharge process. One of the pipe end interfaces of the shut-off valve itself facing away from the first direction is connected to the air pipe 11. The other end of the air pipe 11 is connected to the gas compression tank 5. The other pipe end interface can be used to connect the hose to the raw material. Valve 12 and valve 2 14 are respectively provided on the air pipe 11 and the spray pipe 13. With the support of the above structure, the device can realize the absorption of the curing material raw material and the spraying of the material.

[0039] In summary, in specific implementation, by closing valve 2 14 and opening valve 1 12 and the shut-off valve, a high-speed airflow is ejected from the gas compression tank 5. At this time, only valve 2 14 needs to be closed, and the gas in the pipe will quickly pass through the material pipe 9 and form a negative pressure in the pipe. At this time, a suction effect can be formed by inserting one port of the shut-off valve integrated 10 into the raw material. The negative pressure in the pipe will draw the raw material in and transfer it to the hopper 6. After the mixing is completed, the material is discharged. The connection between the material pipe 9 and the injection pipe 13, as well as the various interfaces of the shut-off valve integrated 10, are all designed with high sealing performance to ensure that no leakage occurs during gas flow and material transfer.

[0040] During spray curing, opening valve 2 (14) allows high-speed gas to flow through spray pipe 13. The negative pressure created by the high-speed airflow through spray pipe 13 not only draws the raw material from hopper 6 into the pipe but also forms a uniform spray stream at the spray gun. Adjusting the opening of valve 2 (14) controls the spray pressure to adapt to the spraying requirements of different curing materials. This design ensures uniform distribution and strong adhesion of the curing material during spraying, thereby improving the curing effect. The entire operation of the equipment is simple and intuitive; feeding and spraying functions are achieved by controlling the opening and closing of the valves. Furthermore, the design of each component considers maintenance needs; for example, the mixing device 8 is easy to disassemble and assemble, facilitating regular cleaning and maintenance, ensuring long-term stable operation of the equipment.

[0041] like Figure 1 As shown, a steering wheel 3 is installed at one end of the frame 1, and a handlebar 2 is installed on the steering wheel 3 to control the direction of the steering wheel 3. An auxiliary wheel 4 is installed at the other end of the frame 1 to ensure the movement of the frame 1. In other words, the maintenance material spraying machine is a mobile device that can be better adapted to actual use.

[0042] The structural design of the equipment fully considers the ease of operation, practicality, and maintenance. The frame 1 has a stepped layout with the mixing device 8 and the gas compression tank 5, and is equipped with a steering wheel 3 and auxiliary wheels 4, which facilitates flexible movement in different work sites. The high sealing design of each connection ensures the reliability of gas and material transfer, prevents leakage, ensures long-term stable operation of the equipment, reduces maintenance costs and equipment failure rate, and extends service life.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
