Referring to fig. 3 and 11, when the excavator is located above a slope for construction, a negative angle is formed between the rotating plate 3 and the horizontal plate 2, one end of the rotating plate 3, which is far away from the excavator, is located at a low position, and at this time, the counterweight block 36 slides towards one end, which is far away from the excavator, so that the movable guard plate 35 and the fixed guard plate 33 are overlapped, and ice soil is accumulated.
Referring to fig. 4 and 12, when the excavator is under the side slope, the rotating plate 3 and the horizontal plate 2 are adjusted to form a positive angle therebetween, the rotating plate 3 is located at a low position near one end of the excavator, and the counterweight block 36 slides toward the end near the excavator to enable the movable guard plate 35 to be unfolded and form a large-area protection structure with the fixed guard plate 33, so that the broken soil is shielded, and the broken soil is prevented from entering the device and affecting the use of the device.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
