Description

Technical Field

[0001] The utility model relates to the technical field of building decoration auxiliary equipment, and more specifically, to a sandblasting machine for building decoration. Background Art

[0002] Sandblasting machine, as an efficient surface treatment equipment, has demonstrated its unique application value in many fields. Its core working principle is to use compressed air as a power source to accurately transport powdered granular materials such as sand and quartz sand from one place to another. In this process, compressed air accelerates the sand to a high-speed motion state, making it carry huge kinetic energy. When these high-speed sand hits the surface of the object, its kinetic energy is quickly converted into potential energy, which effectively cleans the surface of the object through the scouring effect, thereby significantly improving the surface quality of the object. In the field of architectural decoration, sandblasting machines are particularly widely used.

[0003] After searching, the existing Chinese patent announcement number is: CN220863710U, which provides a sandblasting machine for building decoration and renovation. The core working principle of the patent is to drive the moving seat on the reciprocating screw to automatically move up and down through the driving motor, so as to achieve repeated and uniform sandblasting of the target decoration. This design performs well when performing sandblasting operations in indoor environments and can efficiently complete the surface treatment tasks of decorations. However, in actual applications, sandblasting machines not only need to work in indoor environments, but outdoor environments are also common workplaces. The biggest difference between outdoor environments and indoor environments is that there are various uncontrollable natural factors, such as wind, rain, dust, etc., especially in windy weather conditions. Under certain conditions, the blasting media and abrasive particles sprayed by the sandblasting machine are easily affected by the wind, causing the sandblasting path to deviate from the predetermined trajectory, which in turn causes a series of problems. Specifically, when the sandblasting machine is performing sandblasting operations outdoors, the effect of wind will cause some of the sandblasting media and abrasive particles to deviate from the original spraying route. These deviated media and particles may directly adhere to the outer wall of the reciprocating screw. Over time, multiple layers of sandblasting media and abrasive particles will gradually accumulate and solidify on the outer wall of the screw, which not only affects the appearance of the screw, but more importantly, it will increase the friction between the screw and the moving seat, and even cause the moving seat to be unable to move or adjust normally on the screw. Therefore, it needs to be improved and optimized. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The utility model drives two connecting rods to move by the telescopic movement of the output shafts of two hydraulic cylinders I. The two connecting rods drive the moving block to move vertically on the outer wall of the sliding rod. Compared with the existing device adjusted by a lead screw, the hydraulic cylinder I of this device drives the telescopic movement of the piston rod through the flow of hydraulic oil, with a fast response speed and high adjustment efficiency. The lead screw adjustment usually requires manual or motor drive, with a relatively slow speed. Compared with the lead screw adjustment mechanism, the lifting mechanism of this device is not easy to adhere to the sandblasting medium. Even if a small amount of sandblasting medium is mixed into the hydraulic oil, it can be easily solved by replacing the hydraulic oil or cleaning the inside of the hydraulic cylinder. However, it is difficult to clean the sandblasting medium adhered to the outer wall of the lead screw, and long-term accumulation leads to a decrease in adjustment accuracy or even damage to the mechanism. By setting a scraping blade, the utility model enables it to contact the outer wall of the sliding rod, ensuring that when the moving block moves along the sliding rod, the scraping blade can closely follow and clean the surface of the sliding rod, guaranteeing the stable operation and long-term use reliability of the sandblasting machine.

[0014] 2. Through the rotation of the rotating rod, the two U-shaped frames and the vertical and horizontal scraping blades thereon can clean the inside of the storage tank in all directions, ensuring the uniform distribution of the sandblasting medium in the storage tank and avoiding the problem of poor sandblasting effect caused by medium precipitation or stratification. The vertical and horizontal scraping blades are in close contact with the inner wall of the storage tank, which can effectively prevent the sandblasting medium from forming blockage or accumulation on the tank wall, improve the utilization rate of the sandblasting medium, and reduce the frequency and difficulty of equipment maintenance. The design of the U-shaped frame enables the vertical and horizontal scraping blades to cover multiple areas of the storage tank at the same time, realizing efficient cleaning. At the same time, this design also makes the entire stirring device structure compact and occupies a small space, which is beneficial to the overall layout and transportation of the sandblasting machine.

Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 6 shown, the present invention provides a sandblaster for building decoration, including a vehicle body 1. Two support columns 2 are fixedly installed on the top of the vehicle body 1. A first hydraulic cylinder 3 is fixedly installed on one side of the two support columns 2 close to each other. A slide bar 4 is fixedly installed on the top of the vehicle body 1. A moving block 5 is slidably sleeved on the outer wall of the slide bar 4. Connecting rods 6 are respectively hingedly installed on the output shafts of the two first hydraulic cylinders 3. The bottom ends of the two connecting rods 6 are hinged to the outer wall of the moving block 5.

[0024] By using two hydraulic cylinders 3 to drive the lifting mechanism of the sandblasting machine, when the hydraulic cylinder 3 is started, its output shaft will quickly extend and retract, thereby driving two connecting rods 6 to move synchronously. These two connecting rods 6 are ingeniously hinged to the moving block 5, enabling the moving block 5 to stably move vertically on the outer wall of the sliding rod 4. Compared with the traditional lead screw adjustment mechanism, the hydraulic cylinder 3 in this device drives the telescopic movement of the piston rod through the flow of hydraulic oil, having a significant response speed advantage. The sandblasting machine can quickly and accurately adjust to the required working height, greatly improving the adjustment efficiency and production efficiency of the sandblasting operation. The adjustment speed of the lead screw is relatively slow and cannot meet the requirements of modern high-efficiency operations. During the sandblasting operation, the sandblasting medium is easily attached to the surface of the equipment, especially the moving parts of the adjustment mechanism. However, due to its special design and sealing performance, the hydraulic cylinder 3 in this device is not easily attached with the sandblasting medium. Even if a small amount of sandblasting medium is mixed into the hydraulic oil, it can be easily solved by simply replacing the hydraulic oil or cleaning the inside of the hydraulic cylinder, which greatly reduces the equipment maintenance cost and downtime. In contrast, the outer wall of the lead screw adjustment mechanism is easily attached with the sandblasting medium. Long-term accumulation will lead to a decrease in adjustment accuracy and even damage to the mechanism, not only affecting the quality of the sandblasting operation but also increasing the equipment repair cost and downtime. To further ensure the cleanliness and smooth operation of the sliding rod 4, this device is also provided with a wiper blade 8. This wiper blade 8 is in close contact with the outer wall of the sliding rod 4. When the moving block 5 moves along the sliding rod 4, the wiper blade 8 can closely follow and clean the surface of the sliding rod 4, effectively preventing the accumulation of the sandblasting medium on the sliding rod 4 and ensuring the stable operation and long-term use reliability of the sandblasting machine.

[0025] The staff moves the device to the designated location, and then by starting the two hydraulic cylinders 3, the output shafts of the two hydraulic cylinders 3 extend and retract to drive the two connecting rods 6 to move. The two connecting rods 6 drive the moving block 5 to move vertically on the outer wall of the sliding rod 4. At the same time, when the moving block 5 moves along the sliding rod 4, the wiper blade 8 can closely follow and clean the surface of the sliding rod 4, making the outer wall of the sliding rod 4 remain smooth.

[0026] Among them, a storage tank 9 is provided at the top of the vehicle body 1. The top of the storage tank 9 is snap-fitted with a tank cover 10. The top of the tank cover 10 is fixedly installed with an arc-shaped shell 11. A rotating rod 14 is arranged inside the storage tank 9. The rotating rod 14 extends into the arc-shaped shell 11. The rotating rod 14 is rotatably connected to the tank cover 10. Two U-shaped frames 17 are fixedly installed on the outer wall of the rotating rod 14 in the vertical direction. Vertical scraping plates 18 are respectively fixedly installed on the vertical outer walls of the two U-shaped frames 17. Horizontal scraping plates 19 are respectively fixedly installed at the bottoms of the two U-shaped frames 17. The two vertical scraping plates 18 and the horizontal scraping plates 19 are all in contact with the inner wall of the storage tank 9.

[0027] By rotating the rotating rod 14, the two U-shaped frames 17 and the vertical scraping plates 18 and horizontal scraping plates 19 thereon can perform comprehensive cleaning inside the storage tank 9, ensuring the uniform distribution of the sandblasting medium in the storage tank, avoiding the problem of poor sandblasting effect caused by medium precipitation or stratification. The vertical scraping plates 18 and horizontal scraping plates 19 are in close contact with the inner wall of the storage tank 9, which can effectively prevent the sandblasting medium from forming blockages or accumulating materials on the tank wall, improving the utilization rate of the sandblasting medium, reducing the frequency and difficulty of equipment maintenance. The design of the U-shaped frame 17 enables the vertical scraping plates 18 and horizontal scraping plates 19 to cover multiple areas of the storage tank 9 simultaneously, achieving efficient cleaning. At the same time, this design also makes the entire stirring device structure compact and occupies less space, which is beneficial to the overall layout and transportation of the sandblaster.

[0028] The staff first starts the second hydraulic cylinder 12. The output shaft of the second hydraulic cylinder 12 expands and contracts to drive the rack 13 to move. Then, through the meshing relationship between the rack 13 and the gear 15, the rotating rod 14 is driven to rotate. The rotating rod 14 drives the rectangular rod 162 and the U-shaped rod 161 to rotate, so as to fully stir the mixture in the storage tank 9. At the same time, the rotating rod 14 drives the two U-shaped frames 17 and the vertical scraping plates 18 and horizontal scraping plates 19 thereon to perform comprehensive cleaning inside the storage tank 9, preventing the sandblasting medium from forming blockages or accumulating materials on the tank wall.

[0029] Wherein, scraping blades 8 are fixedly installed at the top and bottom of the moving block 5 respectively. The scraping blades 8 are trapezoidally designed, and both scraping blades 8 are in contact with the outer wall of the sliding rod 4 and are slidably connected to the sliding rod 4.

[0030] By designing the scraping blades 8 into trapezoids, they can more effectively contact the outer wall of the sliding rod 4. The two scraping blades 8 are respectively installed at the top and bottom of the moving block 5, and a sliding connection is established between them and the sliding rod 4, ensuring that when the moving block 5 moves along the sliding rod 4, the scraping blades 8 can closely follow and clean the surface of the sliding rod 4.

[0031] Wherein, a second hydraulic cylinder 12 is fixedly installed at the top of the tank cover 10. A rack 13 is fixedly installed on the output shaft of the second hydraulic cylinder 12. A gear 15 is fixedly sleeved on the outer wall of the rotating rod 14, and the gear 15 meshes with the rack 13.

[0032] Through the drive of the second hydraulic cylinder 12, automatic control of the rotating rod 14 can be achieved. The second hydraulic cylinder 12 can precisely control the movement of its output shaft, and then through the meshing relationship between the rack 13 and the gear 15, the rotation control of the rotating rod 14 is realized.

[0033] Among them, a stirrer 16 is fixedly installed on the outer wall of the rotating rod 14. The stirrer 16 is composed of four vertical U-shaped rods 161 and a horizontally placed rectangular rod 162. The four U-shaped rods 161 are circumferentially arrayed around the center of the rotating rod 14, and the rectangular rod 162 is fixedly connected to the inner walls of the four U-shaped rods 161.

[0034] By setting the stirrer 16, when rotating, the rectangular rod 162 and the U-shaped rods 161 can cover various areas around the rotating rod, thereby realizing the full mixing of the materials. Moreover, the circumferential array distribution also increases the stability of the stirrer, making it not easy to deform or damage during high-speed rotation.

[0035] Among them, a nozzle 7 is fixedly installed on the left side of the moving block 5, and a sandblaster 20 is fixedly installed on the top of the vehicle body 1. The sandblaster 20 is fixedly connected to the storage tank 9 and the moving block 5 respectively through rubber hoses 21.

[0036] The nozzle 7 fixedly installed on the left side of the moving block 5 is precisely designed to ensure that the sandblasting medium can be accurately and evenly sprayed onto the wall or floor to be treated. This precision helps to improve the sandblasting effect, reduce unnecessary material waste, and ensure the uniform treatment of the working surface. The high efficiency of the sandblaster 20: The sandblaster 20 fixedly installed on the top of the vehicle body 1 is the core component of the sandblasting system, which can quickly and stably transport the sandblasting medium from the storage tank 9 to the nozzle 7, ensuring the continuity and high efficiency of the sandblasting operation.

[0037] Among them, a push rod 22 is fixedly installed on the top of the vehicle body 1, and the armrest of the push rod 22 is wrapped with high-density sponge.

[0038] The push rod armrest wrapped with high-density sponge provides a soft and comfortable gripping experience. During the pushing process, the operator's hand will not feel discomfort or fatigue due to friction, greatly improving the operation comfort and work efficiency. The material of the high-density sponge has good anti-slip performance. Even when the operator's hand sweats or the weather is humid, it can effectively prevent accidental operations caused by slipping and improve the operation safety.

[0039] The working principle and usage process of the present utility model:

[0040] The staff moves the device to the designated location, and then by starting the two hydraulic cylinders 1-3, the output shafts of the two hydraulic cylinders 1-3 stretch and drive the two connecting rods 6 to move. The two connecting rods 6 drive the moving block 5 to move vertically on the outer wall of the sliding rod 4. At the same time, when the moving block 5 moves along the sliding rod 4, the scraping blade 8 can closely follow and clean the surface of the sliding rod 4, making the outer wall of the sliding rod 4 smooth.

[0041] The staff first starts the second hydraulic cylinder 12. The output shaft of the second hydraulic cylinder 12 expands and contracts to drive the rack 13 to move. Then, through the meshing relationship between the rack 13 and the gear 15, the rotating rod 14 is driven to rotate. The rotating rod 14 drives the rectangular rod 162 and the U-shaped rod 161 to rotate, so as to fully stir the mixed material in the storage tank 9. At the same time, the rotating rod 14 drives the two U-shaped frames 17 and the vertical scraper 18 and the horizontal scraper 19 thereon to be able to perform full-round cleaning inside the storage tank 9, preventing the sandblasting medium from forming blockage or accumulation on the tank wall.
