[0029] In this embodiment, a plurality of ears 41 are provided at intervals along the outer edge of the side cover plate 4, and a fixing through hole is provided on the ear 41. Second ears are welded to corresponding positions on the upper circumferential plate 1 and the lower circumferential plate 2, and a second fixing through hole is provided on the second ear to match. A fixing member, such as a screw, passes through the first fixing through hole and the second fixing through hole to fasten the upper and lower parts of the side cover plate 4 to the upper circumferential plate 1 and the lower circumferential plate 2, respectively.

[0030] When assembling the grinding wheel protection cover body, first fix the upper circumferential plate 1, the lower circumferential plate 2 and the side plate 3 together by welding, then install the grinding wheel, and finally install the side cover plate 4 to close the open cavity formed by the upper circumferential plate 1, the lower circumferential plate 2 and the side plate 3.

[0031] Furthermore, in the present embodiment, a vertical baffle 42 is welded between the lower fixed plate 14 and the lower circumferential plate 2 on one side of the side cover plate 4, and the baffle 42 is located at the square end of the front side of the square-turn circular tube 6, and is used to cover the uncovered gap of the cavity between the rear bottom of the side cover plate 4 and the square-turn circular tube 6; the height of the vertical baffle 42 is equal to the spacing between the lower fixed plate 14 and the lower circumferential plate 2.

[0032] In this embodiment, the upper circumferential plate 1 includes an arc portion 11 and a vertical portion 12 connected to the lower end of the arc portion 11.
