Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model. EMBODIMENT

[0020] Please refer to Figures 1 to 5 The utility model discloses technical scheme: a kind of frequency furnace feeding device provided in the utility model, the frequency furnace used in the present application is the technical structure of existing market, not as detailed description here.

[0021] The present application is aimed at the existing intermediate frequency furnace lacking a feeding mechanism for facilitating feeding during use, which is inconvenient for feeding to the right position and affects feeding efficiency. The present application is provided with a feeding mechanism, which facilitates feeding of materials to the intermediate frequency furnace during dumping. The feeding mechanism can be adjusted according to the dumping height of the materials, thereby facilitating feeding operation.

[0022] The present application adopts a feeding mechanism to stably push the molten iron. Therefore, the present application also includes a feeding mechanism 2, which comprises a lifting mechanism 3 and a feeding frame 55. The feeding frame 55 is open at the outer end. The lifting mechanism 3 comprises a bottom frame 31 and oppositely arranged first and second tooth rods 33. The bottom frame 31 is provided with a wheel body with a wheel brake, which is connected by a long wheel shaft 52. The position of the wheel body can be set according to the actual structure, which facilitates pushing and locking at the designated location. The front ends of the first and second tooth rods 33 are respectively engaged with transmission gears. The transmission gears comprise a first transmission gear 5 and a second transmission gear 51, which are respectively engaged with the first and second tooth rods 33. The first and second transmission gears 51 are connected by a fixed wheel shaft 52. A driving motor 6 with a driving shaft is installed on one side of the bottom frame 31. The model of the driving motor can be flexibly used, which is not the innovation point of the present application. The other end of the wheel shaft 52 penetrates through the bottom frame 31 and is provided with an axle plate 82. The driving motor 6 is connected with the wheel shaft 52 to drive the first and second transmission gears 51 to rotate coaxially. The driving motor 6 is connected with a connecting line, which is provided with a reverse switch. A power plug is arranged at the end of the connecting line. The driving motor 6 is operated by operating the reverse switch. The operating principle is the prior art, which will not be described in detail here. The driving shaft of the driving motor 6 is connected with the wheel shaft 52. The top ends of the first and second tooth rods 33 are connected with the bottom frame 31 through an axle body 81. The bottom surface of the bottom frame 31 is provided with an axle part 8. The axle body 81 penetrates through the axle part 8 and the first and second tooth rods 33 and is provided with an axle plate 82 to form an axle connection structure.

[0023] The rear ends of the first and second tooth rods 33 are provided with a row wheel 7, which is arranged to meet the need of moving on the wheel rail 73. The row wheel 7 comprises a wheel frame 71 and a lifting wheel 72, which is connected in the wheel frame 71 and is arranged from bottom to top. The rear end of the inside of the bottom frame 31 is provided with a wheel rail 73 for the movement of the row wheel 7. It is convenient to stably lift the first and second tooth rods 33. The lateral sides of the first and second tooth rods 33 are respectively provided with a transverse stud 34. The bottom frame 31 is provided with a moving port 35 for the up and down movement of the transverse stud 34. The transverse stud 34 is fixed by a fastener 4. The fastener 4 comprises a fixed nut 41 and a handle body 42 arranged at both ends of the outer periphery of the fixed nut 41. It is convenient to assist in screwing and fixing the lifting position.

[0024] Working principle: as shown in Figure 5 The feeding device adopted by the present embodiment can be placed at the furnace opening of the intermediate frequency furnace and inclinedly arranged at the furnace opening (as shown in Figure 5The lifting mechanism lifts the feeding frame, in which the first and second transmission gears are connected to the shaft body of the driving motor through the shaft, which respectively drive the first and second tooth bars to move up and down. Since the top ends of the first and second tooth bars are connected to the bottom surface of the pushing frame, and the rear ends of the first and second tooth bars move in the wheel rail through the row wheels, the stability of the lifting is increased. When the lifting height needs to be fixed, the transverse stud can be fixed in the moving port through the fastener. Since the feeding frame is connected to the top of the first and second tooth bars, the shaft is inclined. At this time, the feeding frame is aligned with the port of the intermediate frequency furnace after being lifted to the appropriate inclined height.

[0025] When the feeding is completed, the feeding device is removed, and the intermediate frequency furnace is operated to discharge the materials from the discharge nozzle 11.
