[0026] The protective assembly includes a protective plate 7, a second fixed groove block 8, a baffle 9, a rotating block 10, a first hole groove 11 and a protruding block 12. The bottom end of the fixed block 3 is provided with a protective plate 7, the outer wall of the protective plate 7 is fixedly connected with the second fixed groove block 8, the interior of the second fixed groove block 8 is provided with a baffle 9, the interior of the second fixed groove block 8 is rotatably connected to the rotating block 10, the interior of the second fixed groove block 8 is provided with a first hole groove 11, and the top of the protective plate 7 is fixedly connected with the protruding block 12.
[0027] Among them, Figure 3 As shown, the groove block 6 is tightly fitted with the surface of the protrusion block 12, which is conducive to more stably buckling the protective plate 7 on the fixing block 3 for a first engagement.
[0028] Among them, Figure 3 As shown, the midpoints of the fixing column 5 and the first hole 11 coincide with each other, which is conducive to fixing the baffle 9 on the fixing column 5 through the first hole 11 for secondary clamping and fixing.
[0029] Among them, Figure 3As shown, the first fixed slot block 4 forms a snap-fit structure with the second fixed slot block 8 through the baffle 9, the fixed column 5, the first hole groove 11 and the rotating block 10, which is beneficial for the protective plate 7 to rotate the rotating block 10 on the second fixed slot block 8, and then open the baffle 9 so that the baffle 9 is fixed on the fixed column 5 through the first hole groove 11, and then rotate the rotating block 10 to snap the baffle 9, so that the first fixed slot block 4 and the second fixed slot block 8 can be stably fixed together, thereby realizing the fixing operation of the protective plate 7. The design of the protective plate 7 avoids the splashing of gravel during rock crushing, causing damage to surrounding workers and other equipment.
[0030] Example 2
