[0034] By providing the pull ring, the middle groove can be pulled when the middle groove is replaced.

[0035] The working principle of the wear-resistant groove side of the middle groove of the scraper provided by the utility model that can be quickly repaired is as follows:

[0036] The first step: when the middle groove of the scraper is damaged, the middle groove needs to be replaced and repaired to ensure the normal operation of the scraper. At this time, the hexagonal block 9 is rotated, and the hexagonal block 9 drives the threaded rod 8 to rotate. Under the action of the internal threaded sleeve 6, the threaded rod 8 drives the rectangular slider 7 to slide in the rectangular slide 5, and the rectangular slider 7 drives the connecting block 10 to move, and the connecting block 10 drives the trapezoidal block 11 to move, so that the trapezoidal block 11 is away from the triangular block 3, and then the rectangular slider 7 is taken out of the rectangular slide 5. At this time, the middle groove to be replaced can be pulled out through the pull ring;

[0037] Step 2: Now put in the new middle groove, put the rectangular slider 7 into the rectangular slide groove 5, turn the hexagonal block 9, screw the threaded rod 8 into the internal threaded sleeve 6, until the trapezoidal block 11 contacts the triangular block 3, under the action of the triangular block 3 and the trapezoidal block 11, the two adjacent middle grooves will be close to each other, so that the two middle grooves are connected;

[0038] The third step: when it is necessary to prevent the coal from falling out of the middle groove, make the fixed plate 15 face the strip socket 20, pull the pull plate 23, and the pull plate 23 drives the pull rod 17 to move up through the connecting plate 22, and the pull rod 17 drives the circular plate 18 to move up. The circular plate 18 compresses the telescopic spring 19, pushes the coal blocking plate 13, and inserts the fixed plate 15 into the strip socket 20, releases the pull plate 23, and under the action of the elastic force of the telescopic spring 19, the pull rod 17 moves down and is inserted into the positioning hole 21, so that the coal blocking plate 13 can be fixed, and the coal can be prevented from falling out of the middle groove.
