A groove cavity is provided on the upper surface of the support seat 2, and the groove width of the groove cavity corresponds to the specification of the support column 3. The lower end of the support seat 3 is embedded in the groove cavity on the upper surface of the support seat 2 and rotates in accordance with its inner wall. The upper end of the support column 3 is provided with a support plate 7 through a pushing mechanism, and a feeding mechanism for feeding is provided on the side of the support plate 7. The support plate 7 drives the feeding mechanism to move to the Corresponding to the feeding position, to prevent waste caused by a large distance, the outer wall of the support column 3 is sleeved with a first gear 19, and the side wall of the support seat 2 is fixedly installed with a first motor 20. The outer side of the output shaft of the first motor 20 is sleeved with a second gear 21, and the second gear 21 is meshed with the first gear 19. The number of teeth of the first gear 19 is more than the second gear 21, thereby reducing the speed of the support column 3 during rotation, avoiding excessive speed and difficulty in control during circumferential adjustment, and the first gear 19 is fixedly sleeved on the support column through the central mounting hole. 3, the first motor 20 is fixed on the outer surface of the support seat 2 and at a position corresponding to the first gear 19 through a motor seat, the first motor 20 is electrically connected to the external power supply through a wire, and the second gear 21 is fixedly sleeved on the outer surface of the output shaft of the first motor 20 through the central mounting hole. When the vacuum melting furnace is charged, the first motor 20 is connected to the power supply, so that the output shaft of the first motor 20 drives the second gear 21 on the outer surface to rotate, so that the first gear 19 meshing with the second gear 21 drives the support column 3 to rotate, so that the support column 3 drives the feeding hopper 8 to rotate to the direction corresponding to the feeding port of the vacuum melting furnace through the base 4 on the upper surface, ensuring the accuracy of position adjustment, adjusting the direction according to the position of the vacuum melting furnace, making the operation process more convenient, and then the feeding hopper 8 is moved to the feeding port of the vacuum melting furnace by the pushing mechanism, and then the feeding hopper 8 is driven to rotate by the feeding mechanism to feed the material into the vacuum melting furnace, avoiding the feeding distance being too far, thereby ensuring the stability of the feeding process.

[0028] The feeding mechanism includes a fixed seat 16, and the side wall of the fixed seat 16 is fixedly installed with a mounting plate 9 through a symmetrical fixing rod 15. One end of two mutually parallel fixing rods 15 is vertically fixed to the surface of the fixed seat 16, and the other ends of the two fixing rods 15 are vertically fixed to the surface of the support plate 7. The inner cavities of the two mounting plates 9 are rotatably connected with movable shafts 11. The opposite ends of the two movable shafts 11 are symmetrically fixed to the two side walls of the feeding hopper 8 through the fixing plates 25. The inner cavities of the two mounting plates 9 are embedded with mounting bearings, and the two movable shafts 11 are respectively embedded in The inside of the two bearings makes the two movable shafts 11 rotate inside the bearings inside the two mounting plates 9 respectively, and the two ends of the movable shaft 11 extend out of the outside respectively, and the opposite ends of the two movable shafts 11 are symmetrically fixed on the back surfaces of the two fixed plates 25 respectively, and the two fixed plates 25 are fixed on the two side surfaces of the feed hopper 8 respectively. The outer wall of one movable shaft 11 is sleeved with a third gear 31, and the third gear 31 is fixedly sleeved on the outer surface of the movable shaft 11 through the mounting hole opened in the inner cavity, so that the third gear 31 rotates with the corresponding movable shaft 11. The second motor 10 is fixedly mounted on the side wall of the mounting plate 9, and the outer side wall of the output shaft of the second motor 10 is sleeved with a fourth gear 12, which meshes with the third gear 31. The fourth gear 12 is fixedly sleeved on the outer surface of the output shaft of the second motor 10 through a mounting hole opened in the inner cavity. The second motor 10 is electrically connected to an external power supply through a wire. The fixed position of the second motor 10 ensures that the fourth gear 12 meshes with the third gear 31. The feeding hopper 8 is moved to a suitable feeding position by a pushing mechanism, and then the second motor 10 is connected to a power supply so that the second motor 10 is electrically connected to an external power supply through a wire. The output shaft of the machine 10 drives the corresponding fourth gear 12 to rotate, so that the rotating fourth gear 12 drives the meshing third gear 31 to rotate, and the third gear 31 drives the corresponding movable shaft 11 to rotate, so that the feeding hopper 8 rotates between the two mounting plates 9 along with the two movable shafts 11 through the two fixed plates 25. By turning the feeding hopper 8 over, the raw materials inside the feeding hopper 8 are tilted and fed into the furnace, making the operation process more convenient. By adjusting the feeding by a stable position, the stability of the filling operation process is ensured, thereby improving the efficiency of the production and processing process.

[0029] It is worth mentioning that the pushing mechanism includes a base 4, and an electric push rod 5 is fixedly installed on the side wall of the base 4.

The electric push rod 5 is electrically connected to the external power supply through a wire, and the movable end of the electric push rod 5 is fixedly installed on the side wall of the support plate 7. The movable end of the electric push rod 5 is stretched so that the support plate 7 drives the feeding hopper 8 to move to the charging port of the vacuum melting furnace, and then the feeding hopper 8 is rotated to add materials, thereby reducing the distance between the feeding port of the vacuum melting furnace and avoiding falling outside.

[0030] In addition, the two side walls of the base 4 are symmetrically fixed with slide bars 17 through connecting plates 24. The two groups of connecting plates 24 are vertically fixed on the two side surfaces of the base 4 in parallel with each other. The two ends of the two slide bars 17 are vertically fixed between the two groups of connecting plates 24. The outer side of the slide bar 17 is slidably connected with a slider 18. The two sliders 18 are symmetrically fixed on the side walls of the support plate 7. When the position of the feed hopper 8 is adjusted by the movable end of the electric push rod 5, the support plate 7 simultaneously drives the slider 18 to slide on the outer surface of the slider 17. The sliding cooperation between the slider 18 and the slide bar 17 ensures the stability of the moving direction of the feed hopper 8, avoids position deviation, and thus ensures the accuracy of position movement.

A guide groove 22 is circumferentially opened on the side walls of the support seat 2, and two spherical blocks 23 are symmetrically slidably connected to the inner wall of the guide groove 22. A guide groove 22 with a circular cross-section is circumferentially opened on the upper surface of the support seat 2. The spherical blocks 23 are embedded in the guide groove 22 and rotate circumferentially in accordance with the inner wall thereof. In the process of the support column 3 driving the base 4 to rotate, the support column 3 drives the two spherical blocks 23 on the surface of the movable plate 6 to slide in accordance with the inner wall of the guide groove 22 at the same time. The sliding cooperation between the spherical blocks 23 and the guide groove 22 ensures the stability of the rotation adjustment process of the support column 3, thereby ensuring the stability of the adjustment position of the feed hopper 8.
