Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a Figures 1 to 5 flow-following inoculation device for a three-axis linkage pouring machine as shown in the figure, including a base 1 and a lifting mechanism 2 installed on the base 1.

By providing the lifting mechanism 2, the installed flow guiding component 4 can be lifted and adjusted, so that the inoculant added in the flow guiding component 4 can correspond to the feed inlet of the flow deflector 7 when falling, facilitating the inoculant to fall into the molten iron through the flow following pipe 8, enhancing the flexibility of adjustment after the installation of the flow-following inoculation device, and avoiding the problem that the added inoculant is easily spilled to the outside.

[0024] The lifting mechanism 2 includes a limiting component 21. The bottom end of the limiting component 21 is fixed on the base 1. At one end of the base 1 away from the groove opening 5, a stepping motor 22 is fixedly connected. The output shaft of the stepping motor 22 is connected with a bidirectional lead screw 23. The surfaces at both ends of the bidirectional lead screw 23 are installed with fixing plates 24 through bearings. The two ends of the fixing plate 24 are fixedly connected with the lower surface of the limiting component 21. Threaded sleeves 25 are threadedly connected at symmetrical positions on the surface of the bidirectional lead screw 23. The outer wall of the threaded sleeve 25 is fixedly connected with a moving seat 26. The two ends of the moving seat 26 are movably connected with lifting rods 27. The top ends of the lifting rods 27 are installed on the lower surface of the support plate 3 through movable seats 28. By providing driving force through the set stepping motor 22 to drive the bidirectional lead screw 23 to rotate, and then with the cooperation of the threaded sleeve 25, the lifting rods 27 on the moving seat 26 are driven to perform lifting adjustment. Therefore, the guiding component 4 on the support plate 3 can be driven to perform lifting adjustment, so as to adjust the docking distance between the guiding pipe 45 and the guide device 7, enhancing the flexibility of adjustment after the installation of the flow-following inoculation device and avoiding the problem that the added inoculant is easily spilled to the outside.

[0025] The limiting component 21 includes a fixed column 211 and a sliding sleeve 212. The sliding sleeve 212 is embedded in the support plate 3.

Subsequently, by providing the spring 62 with an elastic effect, the distance between the follow - flow pipe 8 at the bottom of the installed flow deflector 7 and the base 1 can be adjusted. Then, it is fixed by the fastening nut 64, thus avoiding the contact between the follow - flow pipe 8 installed too low and the molten iron, and improving the flexibility of the position adjustment of the follow - flow pipe 8.

[0028] Installation holes 9 are provided around the base 1. Fasteners 10 are inserted into the inner cavities of the installation holes 9. By providing the installation holes 9 and the fasteners 10, it is convenient to install the base 1 at the position where the pouring ladle pours molten iron.

[0030] During specific use, first, the base 1 is installed at the position where the pouring ladle pours molten iron through the installation holes 9 and the fasteners 10. Subsequently, according to the situation of the molten iron pouring, the installation position of the flow deflector 7 can be limited by the threaded rod 61. Then, by providing the spring 62 with an elastic effect, the distance between the follow - flow pipe 8 at the bottom of the installed flow deflector 7 and the base 1 can be adjusted. Then, it is fixed by the fastening nut 64, thus avoiding the contact between the follow - flow pipe 8 installed too low and the molten iron, and improving the flexibility of the position adjustment of the follow - flow pipe 8. Then, the stepping motor 22 provides driving force to drive the bidirectional lead screw 23 to rotate. Subsequently, with the cooperation of the thread sleeve 25, the lifting rod 27 on the moving seat 26 is lifted and lowered. Therefore, the flow guiding assembly 4 on the support plate 3 can be lifted and lowered, so that the distance between the connection of the flow guiding pipe 45 and the flow deflector 7 can be adjusted, enhancing the flexibility of the adjustment after the follow - flow inoculation device is installed, and avoiding the problem that the added inoculant is easily spilled to the outside. Finally, the added inoculant can be stored in the flow guiding box 41. The driving motor 42 provides driving force to drive the feeding screw 43 to rotate, so that the added inoculant uniformly falls through the flow guiding pipe 45, and at the same time, the problem of blockage of the inoculant in the flow guiding box 41 is prevented.
