[0033] Figures 1 to 4 This illustration shows an embodiment of the slag cleaning device for a heavy plate feeder of this invention. The device includes a mounting frame 2 located below the heavy plate feeder 1. The mounting frame 2 has a receiving trough 3 and a cleaning mechanism 4. The cleaning mechanism 4 includes a circular rotating mechanism 41 and cleaning bars 42 mounted on the circular rotating mechanism 41. The cleaning bars 42 move with the circular rotating mechanism 41 to sweep the material on the bottom surface of the receiving trough 3 from one end to the other. The receiving trough 3 is located below the heavy plate feeder 1 and is used to clean slag falling from the heavy plate feeder 1.

[0034] The working process of this heavy plate feeder slag cleaning device involves the circular rotating mechanism 41 driving the cleaning strip 42 in a circular motion, sweeping the material on the bottom surface of the receiving trough 3 from one end to the other. Each rotation of the cleaning strip 42 pushes the material on the bottom surface of the receiving trough 3 from one end to the other. First, this heavy plate feeder slag cleaning device does not require repeated moving in and out, making material discharge convenient. Second, the receiving trough 3 always remains below the heavy plate feeder 1 to receive material, eliminating the need for machine stoppages and the risk of material leakage. Third, the receiving trough 3 continuously receives material, resulting in good material reception, and the cleaning mechanism 4 can continuously push material, leading to high discharge efficiency. Fourth, compared to track and scraper trolley installations, it is more suitable for installation in confined spaces below the heavy plate feeder.

[0035] Furthermore, in this embodiment, multiple cleaning strips 42 are provided, and each cleaning strip 42 is arranged at intervals along the movement direction of the annular rotating mechanism 41. In this way, when the annular rotating mechanism 41 moves one revolution, each cleaning strip 42 can push and sweep the material on the bottom surface of the material trough 3 from one end to the other once, further improving the cleaning effect.

[0036] Furthermore, in this embodiment, the cleaning strip 42 is a flexible strip. This prevents the cleaning strip 42 from rigidly contacting the bottom surface of the receiving trough 3 and causing wear on the receiving trough 3. Preferably, the cleaning strip 42 is a rubber strip.

[0037] Furthermore, in this embodiment, the cleaning strip 42 is perpendicular to the movement direction of the circular rotating mechanism 41.

[0038] Furthermore, such as Figure 2 As shown, in this embodiment, the annular operating mechanism 41 includes a drive shaft 411, a driven shaft 412, a drive sprocket 413, and a driven sprocket 414. Both the drive shaft 411 and the driven shaft 412 are mounted on the mounting frame 2 and located above both ends of the receiving trough 3. The drive sprocket 413 is mounted on the drive shaft 411, and the driven sprocket 414 is mounted on the driven shaft 412. A chain 415 is wound between the drive sprocket 413 and the driven sprocket 414. A cleaning bar 42 is mounted on the chain 415. The drive shaft 411 is connected to a drive assembly 416. The drive assembly 416 drives the drive shaft 411 to rotate. The drive shaft 411 drives the chain 415 to move via the drive sprocket 413. The drive sprocket 413 and the driven sprocket 414 keep the chain 415 in an annular state. The movement of the chain 415 drives the cleaning bar 42 to move in an annular motion, sweeping the material on the bottom surface of the receiving trough 3 from one end to the other. The ring-shaped operating mechanism 41 of this structure has a simple overall structure and is easy to manufacture. Of course, the ring-shaped operating mechanism 41 is not limited to the structure of sprockets and chains, but can also adopt the structure of pulleys and belts to fix the cleaning strip 42 on the belt.

[0039] Furthermore, in this embodiment, multiple driving sprockets 413 and driven sprockets 414 are provided and arranged in a one-to-one correspondence. A chain 415 is wound around each corresponding driving sprocket 413 and driven sprocket 414, and a cleaning bar 42 is disposed on each chain 415. Each driving sprocket 413 is arranged at intervals along the axial direction of the driving shaft 411, and each driven sprocket 414 is arranged at intervals along the axial direction of the driven shaft 412. Preferably, the driving shaft 411 and driven shaft 412 are parallel and extend along the width direction of the receiving trough 3. One cleaning bar 42 is driven by multiple chains 415, resulting in smoother operation and better cleaning effect on the bottom surface of the receiving trough 3.

[0040] Furthermore, in this embodiment, the cleaning strip 42 is detachably fixed to the chain 415 by the fixing component 5, facilitating assembly and disassembly. For example, as Figure 4 As shown, the fixing component 5 includes a U-shaped buckle 51, a connecting seat 52, and a nut 53. The U-shaped buckle 51 is mounted on the chain 415, and the connecting seat 52 is fixed to the open side of the U-shaped buckle 51 by the nut 53. The chain 415 is fixed to the connecting seat 52 by bolts 54. The structure is simple and easy to assemble and disassemble. Of course, the cleaning strip 42 can also be directly fixed to the chain 415 by bolts 54 or screws, or fixed to the chain 415 by other means.

[0041] Furthermore, such as Figure 2 and Figure 3 As shown, in this embodiment, the mounting frame 2 is provided with a receiving bin 6 below the discharge end of the receiving trough 3. The receiving bin 6 is used to collect the material falling from the discharge end of the receiving trough 3.

[0042] Furthermore, such as Figure 3 As shown, in this embodiment, the receiving bin 6 is provided with an inclined guide plate 7 below the discharge end of the receiving trough 3, and the material output from the discharge end of the receiving trough 3 is introduced into the receiving trough 3 through the receiving bin 6.

[0043] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
