Referring to fig. 3 and 11, when the excavator is constructed above the side slope, the rotation plate 3 and the horizontal plate 2 are made to have a negative angle, one end of the rotation plate 3 away from the excavator is located at a low position, and at this time, the counterweight 36 slides toward the end away from the excavator, so that the movable guard plate 35 and the fixed guard plate 33 overlap, and ice soil is accumulated.
Referring to fig. 4 and 12, when the excavator is constructed below the side slope, the rotation plate 3 and the horizontal plate 2 are adjusted to have a positive angle, one end of the rotation plate 3 close to the excavator is located at a low position, at this time, the balancing weight 36 slides towards one end close to the excavator, so that the movable guard plate 35 is unfolded, a large-area protection structure is formed with the fixed guard plate 33, and crushed soil is shielded, so that the crushed soil is prevented from entering the device, and the device is prevented from being used.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
