[0024] Embodiment 1: A slag scraper, such as Figure 1 and Figure 2 As shown, it includes a base 1, a working arm 2 arranged on the top of the base 1 for adjustment and a slag bucket 3 connected to the tail end of the working arm 2 for scooping waste slag, a plurality of discharge holes 4 arranged in a matrix for molten iron to pass through are opened in the middle of the slag bucket 3, a dredging component for dredging the discharge holes 4 is arranged in the slag bucket 3, the dredging component includes a limit slider 6, a connecting plate 7 and a dredging rod 9, and a driving part for driving the limit slider 6 to move is arranged in the slag bucket 3, and the driving part includes a sliding seat 10, a second return spring 11 and an extension rod 12.

[0025] The middle of the inner walls opposite to each other of the scraper bucket 3 are provided with limit chutes 5, the limit sliders 6 are slidably connected to the inner walls of the limit chutes 5, and the two ends of the connecting plate 7 are fixedly connected to the outer walls of the two limit sliders 6 on the opposite sides.

[0026] like Figure 2 and Figure 3As shown, a plurality of linearly arranged first sliding holes are provided on the outer wall of the connecting plate 7 close to the discharge hole 4. The first sliding hole and the discharge hole 4 are located on the same axis. The clearing rod 9 is slidably connected to the inner wall of the first sliding hole, and a first return spring 8 is fixedly connected to the wall surface opposite to the clearing rod 9 and the first sliding hole.

[0027] One end of the dredging rod 9 close to the first sliding hole is cylindrical, and one end of the dredging rod 9 close to the discharge hole 4 is a truncated cone with arc-shaped cross sections at both ends.

[0028] like Figure 4 As shown, the inner walls on both sides of the limiting slide groove 5 are provided with fixed grooves, the sliding seat 10 is fixedly connected to the inner wall of the fixed groove, the extension rod 12 is slidably connected to the inner wall of the sliding seat 10, and the fixing groove is provided with a second sliding hole near one end of the limiting slide groove 5, the extension rod 12 is slidably connected in the second sliding hole and fixedly connected to the outer wall of the limiting slider 6.

[0029] A second return spring 11 is fixedly connected inside the sliding seat 10 , and the other end of the second return spring 11 is fixedly connected to one end of the extension rod 12 . The inner wall of the sliding seat 10 is filled with an inert gas.

[0030] In summary, by setting up the driving part and the dredging assembly, the dredging rod 9 enters and exits the discharge hole 4 in turn to dredge the discharge hole 4, thereby preventing the residue from clogging the discharge hole 4, affecting the passage of molten iron, causing waste of molten iron, and affecting work efficiency.

[0031] Embodiment 2: Based on Embodiment 1, refer to Figure 5 The outer walls on both sides of the connecting plate 7 are provided with interconnected scraping grooves 13 and connecting grooves 14, the scraping grooves 13 and connecting grooves 14 are both arc-shaped, and the cross-sections of the scraping grooves 13 and connecting grooves 14 are concave and convex respectively.

[0032] By setting the scraping groove 13 and the connecting groove 14, the arc-shaped design of the scraping groove 13 enables the waste slag to climb through the arc surface of the scraping groove 13 when the connecting plate 7 moves, and climb to the other side of the connecting plate 7 through the connecting groove 14, thereby avoiding a large amount of residue from accumulating at the discharge hole 4, affecting the passage of molten iron and causing waste.

[0033] The working principle of the utility model is as follows: when it is necessary to scrape the waste slag, the working arm 2 drives the scraping bucket 3 to grab the waste slag, and the grabbed molten iron is discharged through the discharge hole 4. When scraping, the temperature in the scraping bucket 3 rises, and the inert gas in the sliding seat 10 can be heated. The inert gas expands and drives the extension rod 12 to slide in the sliding seat 10 to push the limit slider 6, and when the extension rod 12 moves, the second return spring 11 is stretched. When the pulling force of the second return spring 11 is greater than the gas pressure of the inert gas, the second return spring 11 can be used to release the waste slag. The elastic force drives the extension rod 12 to return to its position, which can drive the limit slider 6 to move back and forth in the limit slide groove 5. The limit slider 6 can drive the connecting plate 7 and the dredging rod 9 thereon to move back and forth. When the dredging rod 9 moves to the axis of the discharge hole 4, it can drive the dredging rod 9 to extend into the discharge hole 4 under the action of the elastic force of the first return spring 8 to dredge the discharge hole 4. When the dredging rod 9 moves out of the axis of the discharge hole 4, the dredging rod 9 can be driven back to the first sliding hole under the squeezing of the arc surface of the dredging rod 9 by the inner wall of the discharge hole 4. Then the dredging rod 9 can enter and exit the discharge hole 4 to dredge the discharge holes 4 in turn.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
