[0042] The present utility model will be further described in combination with the following embodiments.

[0043] Embodiment 1.

[0044] As Figures 1 - 3As shown in the figure, an electric arc furnace capable of automatic feeding includes an electric arc furnace body 1. A plurality of support columns 2 are installed on the top of the electric arc furnace body 1. A feeding track 3 is installed on the plurality of support columns 2. Two limit bases 4 are fixedly installed on the outer side of the feeding track 3. An electromagnet 5 is installed on each limit base 4. A blanking port 6 is opened on the feeding track 3. A material conveying bin 7 is slidably connected to the feeding track 3. A magnetic metal block 9 is fixedly installed on the side of the material conveying bin 7. A feeding port 10 is opened on the top of the material conveying bin 7. A discharge port 11 is opened at the bottom of the material conveying bin 7. A feeding mechanism 8 is arranged on the outer side of the electric arc furnace body 1.

[0045] One feeding track 3 is installed on the plurality of support columns 2. The material conveying bin 7 moves on the feeding track 3. The feeding mechanism 8 is provided to convey materials to the material conveying bin 7. The two electromagnets 5 position the material conveying bin 7. The feeding track 3 is provided with a blanking port 6. The discharge port 11 is opened at the bottom of the material conveying bin 7. The electric arc furnace body 1 is fed by gravity.

[0046] As Figure 2 shown in the figure, a limit sliding groove 12 is opened on the inner side of the feeding track 3. A limit sliding block 13 is installed at the position below the magnetic metal block 9 on the side of the material conveying bin 7. The limit sliding block 13 is connected to the limit sliding groove 12 in a clamping manner. One of the electromagnets 5 is installed on the outer side at the highest position of the feeding track 3, and the other electromagnet 5 is installed on the outer side at the blanking port 6 on the feeding track 3.

[0047] When the material conveying bin 7 moves to the highest position of the feeding track 3, the electromagnet 5 at the highest position is turned on, and the other one is turned off. The electromagnet 5 attracts the material conveying bin 7 to stop for replenishing materials.

[0048] Subsequently, the electromagnet 5 at the highest position is turned off, and the other one is turned on accordingly. The material conveying bin 7 moves under the action of gravity and is attracted to stop at the blanking port 6 for feeding.

[0049] After the feeding is completed, the electromagnet 5 at the highest position is turned on again, and the other one is turned off accordingly. The material conveying bin 7 continues to move under the action of gravity and climbs to the highest position again along the smooth part of the feeding track 3 by inertia and is attracted again to achieve circulation.

[0050] As Figure 1 shown in the figure, the feeding mechanism 8 includes a processing bin 81. An inlet 82 is opened at the top of the processing bin 81.

The crushed materials enter the auger conveying channel 85 through the falling channel 84. The first motor 86 drives the auger push rod 87 to convey the materials upward into the material conveying bin 7.

[0052] As Figure 4 shown, the rolling mechanism 83 includes a transmission box 831, which is installed on the side of the processing bin 81.

Both the driven gear A 834 and the driven gear B 838 are fixedly connected to a driven shaft 835, and a rolling roller 836 is installed on each driven shaft 835.

[0054] The second motor 832 drives the driving gear 833 to rotate counterclockwise, driving the driven gear A 834 and the transmission gear 837 to rotate clockwise. The transmission gear 837 drives the driven gear B 838 to rotate counterclockwise, so that the driven gear A 834 and the driven gear B 838 drive the two rolling rollers 836 to rotate towards each other to crush the materials.

[0055] The output shaft of the first motor 86 is rotatably connected to the auger conveying channel 85 through a bearing. The output shaft of the second motor 832 is rotatably connected to the transmission box 831 through a bearing. Each driven shaft 835 is rotatably connected to the processing bin 81 through a bearing. The bearing is a common existing technology.

[0056] In the utility model, a feeding track 3 is installed on the electric arc furnace body 1. A material conveying bin 7 is slidably connected to the feeding track 3. A feeding mechanism 8 is provided to convey materials to the material conveying bin 7. A magnetic metal block 9 is fixedly installed on the side of the material conveying bin 7. Two electromagnets 5 are installed on the side of the feeding track 3. The magnetic metal block 9 and the electromagnets 5 cooperate to fix the stopping position of the material conveying bin 7. The feeding track 3 is provided with a discharging opening 6, and the bottom of the material conveying bin 7 is provided with a discharging port 11. The electric arc furnace body 1 is fed by gravity.
