One side end of the connecting head is provided with an extension arm. The lower end of the other side of the extension arm is provided with a rotating block through a rotating shaft. Both symmetric ends of the rotating block are provided with a telescopic rod. The other end of the telescopic rod is provided with a sliding plate. The lower end of the sliding plate is provided with a telescopic structure, and the lower end of the telescopic structure is provided with a clamping block.
[0007] Further, a plurality of support frames are installed outside the sleeve.
[0008] Further, an installation groove is formed at both symmetric ends of the rotating block, and one end of the telescopic rod is fixedly connected with the inner wall of the installation groove.
[0009] Further, a fixing plate is installed at the lower end of the rotating block, a sliding groove is formed inside the fixing plate, and the sliding plate is slidably connected with the sliding groove.
[0010] Further, the telescopic structure includes a sliding sleeve plate and a telescopic plate. The lower end of the sliding plate is provided with the sliding sleeve plate. The lower end of the sliding sleeve plate is slidably connected with the telescopic plate. The lower end of the telescopic plate is connected with the upper end of the clamping block.
[0011] Further, a conveying crawler is installed on one side of the sleeve and the support frame.
[0012] Furthermore, a plurality of driven clamping plates are slidably connected to one end of each of the two clamping blocks facing each other. A cavity is formed inside the clamping block, and an iron sand layer is filled inside the cavity. One end of the driven clamping plate is in contact with the iron sand layer.
[0013] Furthermore, one extension plate is installed on each side of the sliding plate and above the fixed plate. The extension plate is slidably connected to the upper end of the fixed plate.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] 1. In this application, the lifting rod moves up and down inside the sleeve to change the height of the connecting head. By manual operation, the extension arm is rotated. The extension arm drives the rotating block to move above the material, reducing the height of the connecting head, and then driving the rotating block to lower its height. The two telescopic rods drive the clamping blocks to clamp the material. After clamping, the height of the connecting head is lifted by the lifting rod, and the extension arm is rotated to drive the material to move.

[0023] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.
[0024] As Figures 1-5 shown, the automatic feeding device of the heating furnace in this embodiment includes a sleeve 1. The bottom end of the sleeve 1 contacts the ground, and the upper end of the sleeve 1 is slidably connected with a lifting rod 2. The lifting rod 2 is electrically controlled and can move up and down inside the sleeve 1. The upper end of the lifting rod 2 is rotatably connected with a rotating shaft 3. A driving motor is arranged at the lower end of the rotating shaft 3 and connected to an external power supply. The rotating shaft 3 can be driven to rotate at the upper end of the lifting rod 2 by the driving motor, and a corresponding forward and reverse control circuit needs to be installed for such a driving motor; a connector 4 is installed at the upper end of the rotating shaft 3. The connector 4 is fixedly connected with the rotating shaft 3 and rotates synchronously. A side end of the connector 4 is provided with an extension arm 5. The extension arm 5 is hydraulically driven and can extend and contract in the horizontal direction; at the lower end of the other side of the extension arm 5, a rotating block 7 is installed through a rotating shaft. One telescopic rod 10 is installed at both symmetric ends of the rotating block 7. The telescopic rod 10 is electrically driven, and an electric push rod of a suitable model can be selected for use; the other end of the telescopic rod 10 is installed with a sliding plate 11, and a telescopic structure 12 is installed at the lower end of the sliding plate 11. A clamping block 13 is installed at the lower end of the telescopic structure 12. The telescopic structure 12 can change the vertical height of the clamping block 13, and the two telescopic rods 10 can drive the sliding plate 11 and the clamping block 13 to move in opposite or opposite directions.
[0025] Specifically, a plurality of support frames 6 are installed outside the sleeve 1. One end of each support frame 6 contacts the surface of the sleeve 1, and the other end contacts the ground, which can provide a certain supporting force for the sleeve 1.
[0026] Furthermore, an installation groove 9 is opened at both symmetric ends of the rotating block 7. One end of the telescopic rod 10 is fixedly connected with the inner wall of the installation groove 9, and a part of the telescopic rod 10 is located inside the installation groove 9. The installation groove 9 can provide a certain protection effect for the telescopic rod 10.
[0027] Further, a fixing plate 8 is installed at the lower end of the rotating block 7. A sliding groove 15 is formed inside the fixing plate 8. The sliding plate 11 is slidably connected to the sliding groove 15. The sliding plate 11 can slide inside the sliding groove 15. The sliding groove 15 and the fixing plate 8 can limit the moving direction and trajectory of the sliding plate 11.
[0028] Further, the telescopic structure 12 includes a sliding sleeve plate 1201 and a telescopic plate 1202. The sliding sleeve plate 1201 is installed at the lower end of the sliding plate 11. The telescopic plate 1202 is slidably connected to the lower end of the sliding sleeve plate 1201. The lower end of the telescopic plate 1202 is connected to the upper end of the clamping block 13. The telescopic plate 1202 and the sliding sleeve plate 1201 are driven by electricity. By changing the position of the telescopic plate 1202, the height position of the clamping block 13 can be changed.
[0029] Further, a conveying track 16 is installed on one side of the sleeve 1 and the support frame 6. Through devices such as the sleeve 1, the extension arm 5, and the clamping block 13, the metal materials on the ground can be transported to the conveying track 16, reducing the labor cost.
[0030] Further, a plurality of driven clamping plates 17 are slidably connected to the opposite ends of the two clamping blocks 13. A cavity is formed inside the clamping block 13. An iron sand layer 14 is filled inside the cavity. One end of the driven clamping plate 17 is in contact with the iron sand layer 14. By filling the iron sand layer 14 inside the clamping block 13, when the two clamping blocks 13 need to clamp irregular materials, the edge of the material will first squeeze the plurality of driven clamping plates 17. The plurality of driven clamping plates 17 will squeeze the iron sand layer 14 inward. The plurality of driven clamping plates 17 operate independently. When not clamping materials, under the action of gravity, the iron sand layer 14 will drop again and squeeze the driven clamping plates 17 outward, causing the plurality of driven clamping plates 17 to reset, so that the clamping block 13 can clamp irregular materials with an arc-shaped surface at the edge, and the practicability is higher.
[0031] Furthermore, an extension plate 18 is installed on both sides of the sliding plate 11 and at a position above the fixing plate 8. The extension plate 18 is slidably connected to the upper end of the fixing plate 8. The extension plate 18 is fixedly connected to the sliding plate 11. The fixing plate 8 can provide a certain supporting effect for the extension plate 18, and thus provide a certain supporting effect for the sliding plate 11.
[0032] The usage method of this embodiment is as follows: The lifting rod 2 moves up and down inside the sleeve 1 to change the height of the connecting head 4. By manual operation, the extension arm 5 is rotated, and the extension arm 5 drives the rotating block 7 to move above the material. The height of the connecting head 4 is lowered, thereby driving the rotating block 7 to descend; The two telescopic rods 10 drive the clamping block 13 to clamp the material. After clamping, the height of the connecting head 4 is lifted by the lifting rod 2, and the extension arm 5 is rotated to drive the material to move. There is no need for manual handling of metal materials, which can save labor costs and reduce potential safety hazards to a certain extent.
