Description

Technical Field

[0001] This invention relates to the field of sandblasting technology for building exterior walls, specifically to a sandblasting decoration device for building exterior walls and its usage method. Background Technology

[0002] A sandblasting machine is a device for spraying abrasive materials. The two pipes on the sandblasting gun are a compressed air pipe and a sandblasting pipe. The compressed air pipe is used to provide the compressed air required by the sandblasting gun, while the sandblasting pipe is used to transport the sandblasting material, such as sand or other abrasives. These two lines are usually connected to the sandblasting machine or other compressed air equipment to carry out sandblasting operations.

[0003] When a sandblasting machine is in operation, the sand needs to be mixed and stirred. After the mixed sand is added into the spray gun, the operator can hold the spray gun to sandblast the exterior wall of the building. However, if the mixed sand is not used up within a certain time, it will dry and solidify together. At this time, the sand cannot be used, and the solidified sand is difficult to remove from the inside of the mixing device. Summary of the Invention

[0004] The purpose of this invention is to provide a sandblasting decoration device for building exterior walls and its usage method, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a sandblasting decoration device for building exterior walls and its usage method, comprising a mixing frame, legs fixedly connected to the surface of the mixing frame, a cylindrical frame fixedly connected to the inner wall of the mixing frame, a motor protective frame fixedly connected to the bottom of the inner wall of the mixing frame, a sandblasting machine installed at the bottom of the inner wall of the mixing frame, a sandblasting component installed at the top of the mixing frame, a mixing component installed inside the cylindrical frame, a cleaning component installed on the inner wall of the cylindrical frame, and a feed hole opened on the surface of the mixing frame;

[0007] The sandblasting component includes a motor, which is fixedly connected to the bottom of the inner wall of the mixing frame. A rotating rod is fixedly connected to the output end of the motor. A groove is formed on the surface of the rotating rod. A hollow frame is fixedly connected to the surface of the rotating rod. A discharge hole is formed on the upper surface of the hollow frame. A rotating ring is rotatably connected to the surface of the hollow frame. A lifting frame is slidably connected to the surface of the hollow frame. A curved pipe is connected to the upper surface of the lifting frame. A central disc is connected to the top of the curved pipe. A sandblasting head is connected to the top of the central disc. An electric push rod is fixedly connected to the surface of the lifting frame. A rotating bracket is fixedly connected to the bottom of the electric push rod. The bottom of the rotating bracket is rotatably connected to the top of the mixing frame.

[0008] Furthermore, the motor is located inside the motor protective frame, the end of the rotating rod away from the motor passes through the motor protective frame and extends to the outer end of the motor protective frame, the top of the rotating rod extends to the top outer end of the mixing frame, and the output end of the sandblasting machine is connected to the surface of the rotating ring.

[0009] Furthermore, the lower surface of the lifting frame is in contact with the surface of the hollow frame, the surface of the lifting frame is in contact with the inner wall of the mixing frame, the top of the lifting frame extends to the outer end of the top of the mixing frame, the inner wall of the lifting frame is in contact with the inner wall of the slide groove, and the rotating ring is in communication with the hollow frame.

[0010] Furthermore, the mixing component includes a fixing ring, the inner wall of which is fixedly connected to the surface of the hollow frame, an extension rod fixedly connected to the surface of the fixing ring, a connecting rod fixedly connected to the surface of the extension rod, a mixing rod fixedly connected to the end of the connecting rod, and a semi-circular frame fixedly connected to the surface of the fixing ring.

[0011] Furthermore, the number of extension rods is set to four, and the four extension rods are arranged circumferentially around the fixing ring. The end of the hybrid rod passes through the connecting rod and extends to the outer end of the connecting rod. The fixing ring is set on the lower surface of the hollow frame.

[0012] Furthermore, the cleaning component includes a sliding plate, which is fixedly connected to the surface of a connecting rod. A movable frame is slidably connected to the surface of the sliding plate. A spring rod is fixedly connected to the surface of the movable frame. A scraper is fixedly connected to the end of the spring rod away from the movable frame. A movable plate is hinged to the surface of the movable frame. A diagonal rod is hinged to the end of the movable plate away from the movable frame. The end of the diagonal rod away from the movable plate is hinged to a semi-circular frame. A pressure plate is fixedly connected to the surface of the movable plate. A spring sheet is fixedly connected to the surface of the movable frame.

[0013] Furthermore, the end of the spring piece away from the movable frame is fixedly connected to the surface of the slide plate, the pressure plate is disposed at the end of the movable plate near the inclined rod, and the end of the scraper away from the elastic rod is in contact with the inner wall of the cylindrical frame.

[0014] Furthermore, the method of using the aforementioned sandblasting decoration device for building exterior walls includes the following steps:

[0015] S1: The sand is placed into the inside of the mixing frame through the feed hole. The motor is started to drive the mixing components to mix the sand. The mixed sand enters the inside of the hollow frame through the connection between the sandblasting machine and the rotating ring.

[0016] S2: The sand inside the hollow frame enters the interior of the lifting frame through the discharge hole for storage, and the sand enters the interior of the sandblasting head through the connection between the bent pipe and the central plate for sandblasting.

[0017] S3: The rotating rod drives the extension rod to rotate inside the cylindrical frame through the fixed ring. When the extension rod rotates, it mixes the sand through the mixing rod. Mixing the sand inside the mixing frame avoids the need for manual mixing of the sand separately.

[0018] S4: When the mobile frame moves, the scraper is pushed to contact the inner wall of the cylindrical frame by the elastic rod. The scraper cleans the inner wall of the cylindrical frame by the rotation of the rotating rod, so as to prevent the sand from accumulating on the inner wall of the cylindrical frame during mixing.

[0019] The present invention has the following beneficial effects:

[0020] This invention allows sand to be placed into the mixing frame through a feed hole. A motor is started to drive the mixing components to mix the sand. The mixed sand then enters the hollow frame through the connection between the sandblasting machine and the rotating ring. The sand inside the hollow frame enters the lifting frame through the discharge hole for storage. Finally, the sand enters the sandblasting head through the connection between the curved pipe and the central disc for sandblasting. To adjust the sandblasting height, the electric actuator is activated to move the lifting frame upwards, thus adjusting the sandblasting height. To adjust the angle of the sandblasting head, a rotating rod connects to the lifting frame via a sliding groove, causing the sandblasting head to rotate, thereby adjusting the sandblasting position and improving ease of use.

[0021] The present invention uses a rotating rod to drive an extension rod to rotate inside a cylindrical frame via a fixed ring. When the extension rod rotates, it mixes the sand material through a mixing rod. Mixing the sand material inside the mixing frame avoids the need for manual mixing of the sand material separately, thus improving the convenience of using the mixing frame. The mixed sand material can be stirred again when the angle of the sandblasting head is adjusted to prevent the mixed sand material from agglomerating together.

[0022] The fixed ring of this invention rotates to push the pressure plate to rotate. The pressure plate is pushed by the pressure of the sand to move the inclined rod towards the surface of the slide plate. The movable plate pushes the moving frame to move on the surface of the slide plate. When the moving frame moves, it pushes the scraper to contact the inner wall of the cylindrical frame through the elastic rod. The scraper cleans the inner wall of the cylindrical frame through the rotation of the rotating rod, so as to prevent the sand from accumulating on the inner wall of the cylindrical frame during mixing.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0037] The sandblasting component 4 includes a motor 14, which is fixedly connected to the bottom of the inner wall of the mixing frame 1. A rotating rod 12 is fixedly connected to the output end of the motor 14. A groove 18 is formed on the surface of the rotating rod 12. A hollow frame 19 is fixedly connected to the surface of the rotating rod 12. A discharge hole 21 is formed on the upper surface of the hollow frame 19. A rotating ring 20 is rotatably connected to the surface of the hollow frame 19. A lifting frame 15 is slidably connected to the surface of the hollow frame 19. A bent pipe 17 is connected to the upper surface of the lifting frame 15. A central disc 11 is connected to the top of the bent pipe 17. A sandblasting head 10 is connected to the top of the central disc 11. In this invention, sand is placed into the interior of the mixing frame 1 through the feed hole. The motor 14 is started to drive the mixing component 5 to mix the sand. The mixed sand enters the interior of the hollow frame 19 through the connection between the sandblasting machine 8 and the rotating ring 20. The sand inside the hollow frame 19 enters the interior of the lifting frame 15 through the discharge hole 21 for storage. The sand enters the interior of the sandblasting head 10 through the connection between the bent pipe 17 and the central plate 11 for sandblasting. When the sandblasting height needs to be adjusted, the electric push rod 16 is activated to move upward, which in turn pushes the lifting frame 15 upward, thereby adjusting the sandblasting height. When the angle of the sandblasting head 10 needs to be adjusted, the rotating rod 12 drives the sandblasting head 10 to rotate through the connection between the sliding groove 18 and the lifting frame 15, so as to adjust the sandblasting position of the sandblasting head 10 and improve the convenience of use. The electric push rod 16 is fixedly connected to the surface of the lifting frame 15, and the bottom of the electric push rod 16 is fixedly connected to the rotating bracket 13.

[0040] The mixing component 5 includes a fixing ring 30, the inner wall of which is fixedly connected to the surface of the hollow frame 19.

A mixing rod 34 is fixedly connected to the end of the connecting rod 33. The rotating rod 12 of the present invention drives the extension rod 32 to rotate inside the cylindrical frame 3 through the fixing ring 30. When the extension rod 32 rotates, it mixes the sand through the mixing rod 34. Mixing the sand inside the mixing frame 1 avoids the need for manual mixing of the sand separately, improving the convenience of using the mixing frame 1. The mixed sand can be stirred again when the angle of the sandblasting head 10 is adjusted to prevent the mixed sand from agglomerating. A semi-circular frame 31 is fixedly connected to the surface of the fixing ring 30.

[0041] There are four extension rods 32, which are arranged circumferentially around the fixing ring 30. The end of the hybrid rod 34 passes through the connecting rod 33 and extends to the outer end of the connecting rod 33. The fixing ring 30 is located on the lower surface of the hollow frame 19.

[0042] Cleaning component 6 includes a sliding plate 41, which is fixedly connected to the surface of a connecting rod 33.

A diagonal rod 40 is hinged to the end of the movable plate 43 away from the movable frame 42. The end of the diagonal rod 40 away from the movable plate 43 is hinged to a semi-circular frame 31. When the fixed ring 30 of the present invention rotates, it pushes the pressure plate 47. When rotated, the pressure plate 47 is pushed by the pressure of the sand to move the inclined rod 40 toward the surface of the slide plate 41, and the movable plate 43 pushes the moving frame 42 to move on the surface of the slide plate 41. When the moving frame 42 moves, it pushes the scraper 46 to contact the inner wall of the cylindrical frame 3 through the elastic rod 45. The scraper 46 cleans the inner wall of the cylindrical frame 3 by the rotation of the rotating rod 12, so as to prevent the sand from accumulating on the inner wall of the cylindrical frame 3 during mixing. The pressure plate 47 is fixedly connected to the surface of the movable plate 43, and the spring piece 44 is fixedly connected to the surface of the moving frame 42.

[0044] A method for using a sandblasting decoration device for building exterior walls, comprising the following steps:

[0045] S1: The sand is placed into the interior of the mixing frame 1 through the feed hole. The motor 14 is started to drive the mixing component 5 to mix the sand. The mixed sand enters the interior of the hollow frame 19 through the connection between the sandblasting machine 8 and the rotating ring 20.

[0046] S2: The sand inside the hollow frame 19 enters the interior of the lifting frame 15 through the discharge hole 21 for storage, and the sand enters the interior of the sandblasting head 10 through the connection between the bent pipe 17 and the central plate 11 for sandblasting.

[0047] S3: The rotating rod 12 drives the extension rod 32 to rotate inside the cylindrical frame 3 through the fixed ring 30. When the extension rod 32 rotates, it mixes the sand through the mixing rod 34. The sand is mixed inside the mixing frame 1 to avoid manual mixing of the sand separately.

[0048] S4: When the moving frame 42 moves, the spring rod 45 pushes the scraper 46 to contact the inner wall of the cylindrical frame 3. The scraper 46 cleans the inner wall of the cylindrical frame 3 by rotating the rotating rod 12, so as to prevent the sand from accumulating on the inner wall of the cylindrical frame 3 during mixing.

[0049] In use, sand is placed into the mixing frame 1 through the feed hole. The motor 14 is started to drive the mixing component 5 to mix the sand. The mixed sand enters the hollow frame 19 through the connection between the sandblasting machine 8 and the rotating ring 20. The sand inside the hollow frame 19 enters the lifting frame 15 through the discharge hole 21 for storage. The sand enters the sandblasting head 10 through the connection between the bent pipe 17 and the central disc 11 for sandblasting. When the sandblasting height needs to be adjusted, the electric actuator 16 is activated to move upwards, which in turn pushes the lifting frame 15 upwards, thus adjusting the sandblasting height. When the angle of the sandblasting head 10 needs to be adjusted, the rotating rod 12, connected to the lifting frame 15 via the sliding groove 18, rotates the sandblasting head 10 to adjust its sandblasting position, improving ease of use. The extension rod 32 is driven to rotate inside the cylindrical frame 3 by the fixed ring 30. When the extension rod 32 rotates, it mixes the sand through the mixing rod 34. Mixing the sand inside the mixing frame 1 avoids manual mixing of the sand separately, improving the convenience of using the mixing frame 1. The mixed sand can be stirred again when the angle of the sandblasting head 10 is adjusted to prevent the mixed sand from agglomerating. When the fixed ring 30 rotates, it pushes the pressure plate 47 to rotate. The pressure plate 47 is pushed by the pressure of the sand to move the inclined rod 40 towards the surface of the slide plate 41. And through the movable plate 43, it pushes the moving frame 42 to move on the surface of the slide plate 41. When the moving frame 42 moves, it pushes the scraper 46 to contact the inner wall of the cylindrical frame 3 through the elastic rod 45. The scraper 46 cleans the inner wall of the cylindrical frame 3 through the rotation of the rotating rod 12, preventing the sand from accumulating on the inner wall of the cylindrical frame 3 during mixing.
