[0002] In many fields of industrial production, such as machinery manufacturing, shipbuilding, and large equipment processing, surface treatment of workpieces is a crucial process. Sandblasting is one of the commonly used methods to remove impurities and oxide layers from the workpiece surface, thereby improving the surface quality and performance of the workpiece.
[0003] When handling heavy workpieces, the large weight and volume of the workpieces often require a lot of manpower, resulting in extremely high labor intensity. Traditional sandblasting devices require manual handling of the workpieces. During the handling process, it is difficult to accurately control the movement and placement of the workpieces by relying on manual operation, which can easily lead to collisions between the workpieces and surrounding equipment and facilities. This can not only damage the surface of the workpieces and affect product quality, but may also cause safety accidents. Therefore, it is necessary to design a rotary sandblasting device to clean the outer surface of workpieces to address the above problems. Utility Model Content

Two second electric push rods 13 are fixedly connected to the telescopic ends of the two second electric push rods 13 through the second moving plate 14 and are connected to the second baffle 15 that cooperates with the guide rail 4. The outer wall of the outlet pipe of the sandblasting box 1 is fixedly installed with a conveying channel 20. The conveying channel 20 is rotatably installed with an auger blade 21. The outer wall of the conveying channel 20 is fixedly installed with a motor 22 that is connected to the rotating shaft of the auger blade 21. The outer wall of the sandblasting box 1 is fixedly installed with a bucket elevator 23 that communicates with the conveying channel 20.
[0025] Furthermore, the connecting mechanism includes a connecting shaft 6 fixedly installed on the upper surface of the electric trolley 5. The end of the connecting shaft 6 is rotatably connected to the bottom wall of the rotating disk 7, and multiple holes are provided on the upper surface of the rotating disk 7.
[0026] Furthermore, the first connecting mechanism includes a first connecting plate 8 fixedly installed on the outer wall of the sandblasting box 1, and a first electric actuator 9 fixedly installed on the bottom wall of the first connecting plate 8.
[0027] Furthermore, the second connecting mechanism includes a second connecting plate 12 fixedly installed on the outer wall of the first baffle 11, and a second electric push rod 13 fixedly installed on the inner wall of the second connecting plate 12.
[0028] Furthermore, the outer wall of the sandblasting box 1 is provided with two lower access holes 16 and an upper access hole 17 that communicate with the interior, and the outer wall of the sandblasting box 1 is provided with a lower observation port and an upper observation port that communicate with the interior.
[0029] Furthermore, a lower observation window 18 is fixedly installed inside the lower observation port, and an upper observation window 19 is fixedly installed inside the upper observation port.
[0030] In practical use, the working principle of this utility model is as follows:
[0031] The sandblasting box 1 is equipped with components such as a spray gun and pipes. These components use mature devices from existing technologies, and their specific structures and working mechanisms will not be described in detail in this solution.
[0032] The specific working principle is as follows: When sandblasting a workpiece, the workpiece is first hoisted onto the upper surface of the rotating disk 7 and placed there. Then, the electric trolley 5 can move the workpiece into the sandblasting box 1 through the cooperation of two guide rails 4 and the movable opening. Immediately afterwards, the first electric push rod 9 can drive the first baffle 11 to move downward through the first moving plate 10, thereby blocking the movable opening. After the movable opening is blocked, the second electric push rods 13 on both sides can drive the second baffles 15 on the same side to move through the cooperation of the second moving plates 14. This allows the two second baffles 15 to block the inner wall of the guide rail 4 on the same side. After shielding, it can effectively prevent abrasive from splashing out along the gap of guide rail 4 during sandblasting, ensuring that sandblasting is carried out in a relatively enclosed space, and ensuring the safety and cleanliness of the working environment. At this time, the sandblasting equipment is started, and the operator can hold the sandblasting gun through the upper hand hole 17 to start spraying high-speed abrasive onto the surface of the workpiece to grind and clean the outer surface of the workpiece. Since the rotating disk 7 is rotatably connected to the electric carriage 5 through the connecting shaft 6, during the sandblasting process, the rotating disk 7 can be manually rotated around the connecting shaft 6 through the lower hand hole 16 according to the shape of the workpiece and the parts to be cleaned, so that all surfaces of the workpiece can be evenly sandblasted, greatly improving the cleaning effect and comprehensiveness.
[0033] Meanwhile, operators can observe the sandblasting situation inside the sandblasting box 1 in real time through the lower observation window 18 and the upper observation window 19, including the abrasive spraying status and workpiece cleaning progress, so as to promptly identify problems and take corresponding measures. During the continuous sandblasting operation, the abrasive continuously impacts the workpiece surface, removing impurities, oxide layers and other attachments. At the same time, some abrasive and the removed impurities will fall downward through multiple holes on the upper surface of the rotating disk 7. After the falling abrasive and impurities fall into the bottom of the sandblasting box 1, they will move towards the outlet pipe under the action of gravity. When they reach the outlet pipe, the motor 22 drives the auger blades 21 in the conveying channel 20 to rotate. The auger blades 21 transport the abrasive and impurities along the conveying channel 20, and finally transport them to the bucket elevator 23 connected to the conveying channel 20. After the bucket elevator 23 is started, it lifts these abrasive and impurities to a high place, which facilitates the subsequent screening, recycling and reuse of abrasive, and centralized treatment of impurities, reducing resource waste and environmental pollution.

Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
