The slag scraper arm 6 includes a basic arm 61, and a telescopic arm 62 is provided within the basic arm 61. The support shaft 3 is connected to the telescopic arm 62 via a connecting pin 7. There are three transverse reinforcing ribs 5, one of which is arranged at the short side of the isosceles trapezoid of the front plate 1 and two are arranged at the rectangular plate. The three transverse reinforcing ribs 5 are arranged parallel to the short side; there are two vertical reinforcing ribs 4, which are symmetrically arranged along the center line of the isosceles trapezoid of the front plate 1. The length of the vertical reinforcing ribs 4 is equal to the sum of the height of the isosceles trapezoid of the front plate 1 and the width of the rectangular plate; the front plate 1 adopts a shape combining an isosceles trapezoid and a rectangular plate, which can reduce the material consumption of the front plate 1 while ensuring the maximum operating area; by arranging reinforcing ribs on the front plate 1, the thickness of the reinforcing ribs is 35 mm and is connected to the front plate 1 by welding, the structural strength of the front plate 1 during the slag removal process can be ensured, and the finite element analysis reference Figure 4 When the front plate 1 is in working condition, it only bears stress on one side of the reinforcing rib, one side of the front plate transition plate 2 and one end of the rectangular plate. After the reinforcing ribs are set on the front plate 1 in the above-mentioned manner, when it is subjected to a stress of 70 MPa, the maximum deformation of the front plate 1 is guaranteed not to exceed 1.2 mm, which fully ensures the structural integrity of the front plate 1 and improves the rigidity of the front plate 1.

[0027] The interior of the basic arm 61 is provided with a grooved guide rail along the direction of the arm body, and the telescopic arm 62 is installed in the grooved guide rail. The tail of the basic arm 61 is provided with a telescopic motor. By providing the telescopic motor and the grooved guide rail, the telescopic arm 62 can move along the length direction of the basic arm 61 to complete the telescopic action.

[0028] The telescopic arm 62 includes a first-level telescopic arm 62, a grooved guide rail is arranged along the arm body direction in the first-level telescopic arm 62, and a second-level telescopic arm 62 is installed in the grooved guide rail; by setting the telescopic arm 62 as a first-level telescopic arm 62 and a second-level telescopic arm 62, the telescopic range of the slag scraping arm 6 is further improved, and slag scraping work can be performed in a larger range.
