Technical Field
[0001] This utility model relates to the field of pneumatic tool manufacturing technology, and more specifically, to a pneumatic rust removal shovel. Background Technology
[0002] A pneumatic rust remover is a pneumatic tool that uses compressed air as a power source. It is mainly used to remove rust and dirt from metal surfaces. It drives the scraper head to move repeatedly through compressed air, thereby chiseling metal or building materials to achieve the effect of rust removal and cleaning. For example, it can be used to clean the facade of ships and the superstructure at a height of 4-5m.
[0003] First, the existing pneumatic rust removal chisels have a single-point impact and a small rust removal area, resulting in low efficiency. Second, the angle of the pneumatic rust removal chisels is not adjustable, which means that they cannot adapt well to different surfaces and corner areas in actual use, resulting in low flexibility. Finally, they cannot absorb dust during operation, and the scattered dust will not only pollute the environment but also be inhaled by workers, thus endangering their health.
[0004] Therefore, a pneumatic rust removal scraper is proposed to address the above problems. Utility Model Content

A connecting groove is opened at one end of the first connecting rod, and the rolling ball is movably connected within the connecting groove. A locking bolt is threaded onto the outer side of the first connecting rod, and one end of the locking bolt abuts against the rolling ball. A dust collection hood is bolted to the connecting base, and a dust collection assembly is provided between the connecting base and the dust collection hood.
[0007] Preferably, the dust collection assembly includes a dust collection chamber, a dust collection head, and a connecting pipe. The dust collection chamber is provided on the upper surface of the connecting base and inside the dust collection hood. The top of the dust collection chamber is connected to the connecting pipe. A plurality of dust collection heads are connected at equal intervals on the surface of the dust collection chamber, and the dust collection heads are connected and communicate with the dust collection chamber.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1
[0021] As attached Figures 1 to 4 The pneumatic rust removal shovel shown includes a connecting base 8 and a rust removal shovel body 9. Multiple detachable rust removal shovel bodies 9 are installed on the connecting base 8 at equal intervals via connecting blocks 14. A second connecting rod 7 is fixedly connected to one side of the connecting base 8. A rolling ball 6 is connected to one end of the second connecting rod 7. A first connecting rod 4 is provided on the outside of the rolling ball 6. A connecting groove 5 is opened at one end of the first connecting rod 4. The rolling ball 6 is movably connected in the connecting groove 5. A locking bolt 15 is threadedly connected to the outside of the first connecting rod 4. One end of the locking bolt 15 is in contact with the rolling ball 6. A dust collection hood 16 is bolted to the connecting base 8. A dust collection assembly is provided between the connecting base 8 and the dust collection hood 16.
[0022] The device expands the rust removal area by using multiple rust-removing shovel bodies 9 mounted on the connecting base 8, thereby improving work efficiency. Simultaneously, the connecting base 8 can be rotated, causing the second connecting rod 7, which is fixedly connected to the connecting base 8, and the rolling ball 6 connected to the second connecting rod 7 to rotate. The rolling ball 6 then rotates within the connecting groove 5 at one end of the first connecting rod 4, adjusting the angle of the connecting base 8 and the rust-removing shovel bodies 9 mounted on the connecting base 8 to a suitable position. Subsequently, the locking bolt 15 threaded onto the first connecting rod 4 is rotated, causing one end of the locking bolt 15 to tightly press against the rolling ball 6, thus limiting and fixing the rolling ball 6. This structure allows for multi-angle adjustment and rotation of the connecting base 8 and the rust-removing shovel bodies 9 mounted on the connecting base 8, better adapting to different surfaces and corner areas, and improving flexibility.
[0023] Example 2
[0024] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:
[0025] In a preferred embodiment, the dust collection assembly includes a dust collection chamber 11, a dust collection head 12, and a connecting pipe 13. The dust collection chamber 11 is disposed on the upper surface of the connecting base 8 and inside the dust collection hood 16. The top of the dust collection chamber 11 is connected to the connecting pipe 13. A plurality of dust collection heads 12 are evenly connected and disposed on the surface of the dust collection chamber 11. The dust collection heads 12 are connected and communicate with the dust collection chamber 11. One end of the connecting pipe 13 is fixedly inserted through the surface of the dust collection hood 16, and the other end of the connecting pipe 13 is connected to the input end of the dust collection pump. Furthermore, when the device is in use, the power supply of the dust collection pump connected to one end of the connecting pipe 13 is first turned on. The dust collection pump sucks up and collects the scattered dust through the connecting pipe 13, the dust collection chamber 11, and the dust collection head 12, thereby reducing dust pollution and improving the practicality of the device.
[0026] In a preferred embodiment, a cylinder 2 is provided on one side of the first connecting rod 4, and a piston rod 3 is provided inside the cylinder 2. The end of the piston rod 3 away from the cylinder 2 is fixedly connected to one end of the first connecting rod 4. A hand handle 1 is connected to the end of the cylinder 2 away from the piston rod 3, and a handle 10 is connected to one end of the hand handle 10. The handle 10 is provided with rough texture to increase the friction between the hand and the handle 10. Furthermore, when using the device, the entire device can be lifted by first holding the handle 10. Then, the piston rod 3 at the free end of the cylinder 2 drives the first connecting rod 4 to extend and retract. The extension and retraction of the first connecting rod 4 drives the connecting base 8 and the rust removal shovel body 9 provided on the connecting base 8 to extend and retract. The rust removal shovel body 9 performs rust removal operations through the extension and retraction of ...
[0027] The working process of this utility model is as follows: First, hold the handle 10 to lift the entire device. Then, the piston rod 3 set at the free end of the cylinder 2 drives the first connecting rod 4 to move telescopically. The telescopic movement of the first connecting rod 4 drives the connecting base 8 and the rust removal shovel body 9 set on the connecting base 8 to move telescopically. The rust removal shovel body 9 performs rust removal operation through telescopic movement. At the same time, turn on the power supply of the dust pump connected to one end of the connecting pipe 13. The dust pump sucks up and collects the scattered dust through the connecting pipe 13, the dust suction chamber 11, and the dust suction head 12.
[0028] When the angle of the connecting base 8 and the rust removal shovel body 9 set on the connecting base 8 needs to be adjusted, the connecting base 8 can be rotated. The second connecting rod 7, which is fixedly connected to the connecting base 8, and the rolling ball 6 connected to the second connecting rod 7 will rotate. Then, the rolling ball 6 will rotate in the connecting groove 5 opened at one end of the first connecting rod 4, thereby adjusting the angle of the connecting base 8 and the rust removal shovel body 9 set on the connecting base 8 to a suitable position. Then, the locking bolt 15 threaded on the first connecting rod 4 will be rotated, so that one end of the locking bolt 15 tightly abuts against the rolling ball 6, thereby limiting and fixing the rolling ball 6. This structure can adjust and rotate the connecting base 8 and the rust removal shovel body 9 set on the connecting base 8 at multiple angles, thereby better adapting to different surfaces and corner areas and improving flexibility. The above is the working principle of this pneumatic rust removal shovel.
