When the scraper block 14 passes through the first guide groove 23, the second guide groove 24 and the straight groove of the third guide groove 25, the scraper 20 and the scraper block 14 rotate relative to each other, and the movable mechanism and the sliding rod rotate. The scraper 20 rotates relative to the scraper block 14 through the movable mechanism, and the scraper 20 is always in contact with the bottom of the discharge port 12. At this time, the extension plate 21 moves relatively linearly with the scraper 20 along the straight groove in the first guide groove 23, thereby expanding the pushing area of ​​the scraper 20 and the extension plate 21. By expanding the pushing area, the waste slag is completely pushed out, and then the scraper block 14 is reset.

[0039] Example 2 like Figures 1 to 8 As shown, this embodiment provides a method for discharging slag from a waste incinerator, comprising: The overall structure is moved by the universal wheel 33. When it moves to the required position, the servo motor 38 causes the power wheel 39 to rotate axially through the output shaft. The transmission wheel 30 and the power wheel 39 rotate synchronously through the transmission belt 32. The internal threaded sleeve 31 fixed to the transmission wheel 30 rotates synchronously. The internal threaded sleeve 31 pushes the threaded column 35 downward through the thread, so that the bottom plate 36 on the threaded column 35 is lifted off the ground, thereby completing stable placement. The water pump is connected to the external water channel, and the water pump sends water to the slag box 4 to freeze the waste slag. The overflowed water enters the buffer water tank 3 and is discharged by the drain machine (generally discharged into the wastewater pool). The metal filter screen 11 is used to prevent the waste slag from flowing out. The waste slag falls into the slag box 4 through the discharge port 12. The hydraulic rod 26 causes the rotating shaft 29 to rotate axially through the force arm 27 in the form of telescopic movement. The rotating shaft 29 pushes the scraper block 14 through the arm plate 15. When the scraper When the block 14 passes through the straight grooves of the first guide groove 23, the second guide groove 24 and the third guide groove 25, the scraper 20 and the scraper block 14 rotate relative to each other, the second concave frame 16 and the sliding rod rotate, and at the same time the sliding rod 19 is pulled out in the second concave frame 16, and the second spring 17 is compressed. It can be seen that the scraper 20 rotates relative to the scraper block 14 through the movable mechanism, and the scraper 20 is always in contact with the bottom of the discharge port 13. At this time, the extension plate 21 moves relative to the straight groove in the first guide groove 23 and the scraper 20 in a straight line, so that the pushing area of ​​the scraper 20 and the extension plate 21 is expanded. In this way, the waste residue is completely pushed out by expanding the pushing area. When the scraper block 14 is reset, the cam 5 lifts the connecting plate 6, and the connecting plate 6 moves up through the first concave frame 10. The first concave frame 10 cleans the metal filter 11 through the scraper plate, thereby ensuring that the metal filter 11 can always maintain normal filtering work.
