Sand casting has short production cycle, low product cost, and product batch size and size are not limited, which is a basic process in casting production. With the development of technology, the core sand material for sand casting has been continuously improved. Self-hardening resin sand can be self-hardened by the action of catalyst at room temperature. Due to its high strength, convenient molding, and high dimensional accuracy of core, it has been widely used in casting production. In the working process of drill bit, debris and other objects will be stuck in the gap of drill bit. In the sand cleaning process, the drill bit may be damaged by knocking, vibration and other methods while sweeping off the debris.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1-6 As shown: An automatic sand-removing device for a sand-rotating drill bit includes a mounting base 1 and a base 12. A drill base 8 is provided on the base 12, and a drill bit 9 is provided on the drill base 8. Air blowing components are provided on both sides of the drill bit. The air blowing components include an exhaust pipe 3, a rigid pipe 7, and an exhaust port 10. A rotation limiting component is connected to one side wall of the exhaust pipe 3. The rotation limiting assembly includes a connecting column 21, a rotating column 11, a locking block 18, a limiting column 19, and a shrinking block 20, all fixedly connected to one side wall of the exhaust pipe 3. A mounting base 1 is connected to the other side wall of the exhaust pipe 3. A locking structure is provided below the mounting base 1. A connecting port 13 and a first pipe 14 are provided inside the exhaust pipe 3 to connect the air blowing assembly to the drill bit at the bottom of the drill. The rotation limiting assembly allows the mounting base 1 to rotate, thereby adjusting the vertical angle of the hard tube and enabling impact on the drill bit from more angles. Simultaneously, the locking assembly can adjust the angle of the mounting base 1 360 degrees laterally, further expanding the range of angle adjustment for the exhaust port 10, better cleaning the drill bit 9, improving the cleaning effect while avoiding damage to the drill bit 9.

[0018] The bottom of the mounting base 1 is connected to a receiving plate 2, which is located on the base 12. A quick air pipe connector 5 is provided on one side wall of the mounting base 1. The quick air pipe connector 5 is connected to the drill bottom 8. The mounting base 1 is provided with a flat-end screw 6. The rigid pipes 7 are arranged at an angle. The exhaust port 10 is aligned with the drill bit 9. The two rigid pipes 7 have a certain degree of inclination, so that the exhaust port 10 is aligned with the drill bit 9. The two exhaust ports are aligned with the drill bit 9, which allows for more angles of blowing on the drill bit 9 and better cleaning of the debris and other objects stuck inside.

[0019] The bottom of the connecting plate 2 is provided with a locking structure, which includes a rotation limiting plate 22, a displacement column 23, a spring 24, and a locking block 25. The limiting plate 22 is fixedly connected to the bottom of the connecting plate 2 via a vertical rod. The rotating mounting base 1 can drive the rotation limiting plate 22 to rotate. The bottom of the vertical rod is fixedly connected to the rotation limiting plate 22. The limiting plate 22 has multiple slots. The end of the locking block 25 is provided with a protrusion. The size of the protrusion is the same as that of the slot on the limiting plate 22, and it can be locked into the slot.

[0020] The working principle of the locking and structure is as follows: First, the moving block 15 moves backward, driving the displacement column 23 and the locking block 25 to move backward. At this time, the spring 24 contracts, and the locking block 25 leaves the slot on the rotating limit plate 22. At this time, the mounting base 1, the exhaust pipe 3, and the rotating limit assembly can be rotated as a whole. The rotating limit plate 22 rotates synchronously with it. After the angle is adjusted, the moving block 15 is released. Under the tension of the spring 24, the locking block 25 is locked into the slot on the rotating limit plate 22, thereby fixing the mounting base 1 and adjusting the angle.

[0021] The other end of the card and block 25 is provided with a horizontal column, and the end of the horizontal column is provided with a spring 24. The other end of the spring 24 is fixedly connected to the inside of the base 12. A displacement column 23 is fixedly connected to the card and block 25. A moving block 15 is fixedly connected to the upper end of the displacement column 23. The moving block 15 extends out of the base 12.

[0022] The rotation limiting assembly includes a rotating column 11, a locking block 18, a limiting column 19, and a shrinking block 20. One end of the rotating column 11 is fixedly connected to a connecting column 21, and the other end of the connecting column 21 is connected to the side wall of the exhaust pipe 3. The connecting column 21 extends into the interior of the fixing plate 17.

[0023] The working principle of the rotation limiting assembly is as follows: Under normal conditions, the end of the clip and block 18 is engaged in the limiting groove 16 on the rotating column 11, and the rotating column 11 cannot be rotated at this time. When the end of the clip and block 18 is pressed down, the shrinking block 20 that abuts against the limiting column 19 shrinks, and the clip and block 18 rotates counterclockwise. The part with the protrusion is lifted up, and the rotating column 11 can be rotated, which drives the connecting column 21 to rotate synchronously with the exhaust pipe 3. At this time, the blowing angle of the exhaust pipe 3 changes accordingly, and it can be adjusted accordingly. When it is adjusted to a suitable position, the clip and block 18 is released, and the shrinking block 20 expands to lift the limiting column 19. At this time, the protrusion at the end of the clip and block 18 is engaged in the limiting groove 16, thereby completing the fixed limiting of the position of the exhaust pipe 3.

[0024] The portion of the connecting post 21 that extends into the fixed plate 17 is covered by a round tube. A shrinkage block 20 is fixed on the round tube. The position of the round tube will not rotate with the rotation of the connecting post 21 and the rotating post 11. The position of the shrinkage block 20 will also not change. A limiting post 19 is provided above the shrinkage block 20. A through groove is provided on the fixed plate 17 at the position corresponding to the limiting post 19, allowing the limiting post 19 to move, thereby enabling the card and block 18 to rotate.

[0025] The end of the limiting post 19 is fixed to the end of the card and block 18. The card and block 18 is rotatably connected to the inside of the fixing plate 17. The other end of the card and block 18 is fixed with a downward protrusion. The rotating post 11 has multiple limiting grooves 16 circumferentially opened. The size of the protrusion is the same as the size of the limiting groove 16 and the position corresponds to it.

[0026] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
