They do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] A device for feeding baled material into an upper furnace, such as Figure 1 and Figure 2 As shown, it includes an upper furnace 12, a feeding mechanism arranged on the side of the upper furnace 12, and a feeding clamp arranged on the feeding mechanism. The feeding clamp is provided with an automatic clamping mechanism, which automatically releases the material bag 11 when the feeding clamp approaches the furnace mouth. The automatic clamping mechanism includes a driving cylinder 5 arranged on the feeding clamp, a controller 14 arranged on the driving cylinder 5, and a clamp sensor 15 arranged on the opening of the upper furnace 12.

[0029] To provide support for the charging fixture, the controller is triggered to activate the drive cylinder 5. Two steel pipes 16 are symmetrically installed on either side of the opening of the upper furnace 12. The two steel pipes 16 are arranged parallel to the top of the upper furnace 12. The fixture sensor 15 is installed on at least one of the steel pipes 16. During the charging fixture's descent, when it hits the furnace opening steel pipe 16, the charging fixture opening opens, and the material bag falls into the molten copper, completing the charging process.

[0030] In order to facilitate long-distance feeding, the feeding mechanism includes a cantilever crane 13, an electric hoist 17 arranged on the cantilever crane 13, and the feeding fixture is arranged on the electric hoist 17. The cantilever crane 13 can rotate and the electric hoist 17 can translate, which is convenient for feeding.

[0031] like Figure 3-Figure 9 As shown, the feeding clamp includes a first connecting rod mechanism and a second connecting rod mechanism, the middle parts of the first connecting rod mechanism and the second connecting rod mechanism are connected by a first hinge 3, one end of the first connecting rod mechanism and the second connecting rod mechanism is connected by a second hinge 4, and the other end of the first connecting rod mechanism and the second connecting rod mechanism is provided with a clamping member 8, and a driving cylinder 5 for adjusting the opening size of the clamping member 8 is provided between the first hinge 3 and the second hinge 4.

[0032] In order to facilitate rotation, swinging and movement to adapt to complex movements in planes and spaces, the first link mechanism includes a first link 1 and a third link 6, and the first link 1 and the third link 6 are hinged by a first bolt 9. The second link mechanism includes a second link 2 and a fourth link 7, and the second link 2 and the fourth link 7 are hinged by a second bolt 10. The first hinge 3 hinges the first link 1 and the second link 2, and the second hinge 4 hinges the third link 6 and the fourth link 7.

[0033] To facilitate adjustment of the opening size of the clamping member 8, the cylinder seat of the driving cylinder 5 is hinged to the second hinged member 4, and the piston head of the driving cylinder 5 is hinged to the first hinged member 3. The clamping member 8 includes a first clamping member 81 and a second clamping member 82 symmetrically arranged on the first connecting rod 1 and the second connecting rod 2. The first clamping member 81 and the second clamping member 82 cooperate to clamp the material bag 11.

[0034] To facilitate installation and fixation, the first clamping member 81 includes a first clamping wing 811 obliquely disposed on the first connecting rod 1, a first clamping plate 812 fixedly disposed inside the first clamping wing 811, and the first clamping plate 812 is fixed to the first clamping wing 811 via a first clamping bolt 813. The second clamping member 82 includes a second clamping wing 821 obliquely disposed on the second connecting rod 2, a second clamping plate 822 fixedly disposed inside the second clamping wing 821, and the second clamping plate 822 is fixed to the second clamping wing 821 via a second clamping bolt 823.

[0035] To prevent the material bag 11 from escaping during movement and to facilitate clamping of the material bag 11, at least one first clamping bolt 813 is provided between the first clamping wing 811 and the first clamping plate 812, with the head of the first clamping bolt 813 embedded in the inner side of the first clamping wing 811. At least one second clamping bolt 823 is provided between the second clamping wing 821 and the second clamping plate 822, with the head of the second clamping bolt 823 embedded in the inner side of the second clamping wing 821.

The second clamping bolt 823 is equipped with a second elastic washer 824, positioned between the second clamping wing 821 and the second clamping plate 822. Because the first and second clamping wings 811, 821 are tilted relative to each other, the first and second clamping bolts 813, 823 are tilted relative to each other. By hooking the material pack 11 with the first and second clamping bolts 813, 823 utilize the weight of the material pack 11 to clamp the material pack 11. The provision of the first and second elastic washers 814, 824 provides a certain cushioning effect, thereby extending the service life of the first and second clamping bolts 813, 823.
