[0028] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0029] like Figures 1-6 As shown, the central rotating body protection and flow guiding device provided in this embodiment includes a rock grabber body 1, a grabber 2, and a cab 3. A flow guide 4 is provided below the cab 3, and multiple buffer components 5 are installed between the flow guide 4 and the cab 3. A splash guard 6 is installed on the outer wall of the flow guide 4. The flow guide 4 reverses the flow of shock waves and rocks, thereby greatly reducing the deformation and equipment damage caused by blasting shock waves and rock impacts to the rock grabber. The splash guard 6 increases the shielding area, preventing the rocks guided by the flow guide 4 from rising upwards, thus further protecting the rock grabber. The buffer components 5 buffer the impact, thereby mitigating its impact.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the fairing 4 is a conical fairing, welded from a 5mm thick steel plate. The conical shape of the fairing 4 improves the airflow guiding effect.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, first fixing plates 7 are fixedly connected to the outer walls of all four sides of the cab 3. A sliding rod 8 is fixedly connected to the bottom of the first fixing plate 7. Second fixing plates 9 are fixedly connected to the outer walls of all four sides of the fairing 4. A sliding hole 10 is provided at the top of the second fixing plate 9, which slides through the sliding rod 8. A support plate 11 located at the bottom of the second fixing plate 9 is fixedly connected to the bottom end of the sliding rod 8. The fairing 4 can be supported by the sliding rod 8, the sliding hole 10, and the support plate 11.

[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the splash guard 6 and the fairing 4 are rotatably connected by a hinge 12. A pull rope 13 connects the top of the splash guard 6 to the outer wall of the cab 3. A first hanging ring 14 is fixedly connected to the top of the splash guard 6, and a second hanging ring 15 is fixedly connected to the outer wall of the cab 3. Since the splash guard 6 and the fairing 4 are rotatably connected by a hinge 12, and the top of the splash guard 6 is connected to the outer wall of the cab 3 by a pull rope 13, when not in use, the pull rope 13 is released, and the splash guard 6 automatically stands upright under gravity, thus reducing space occupation and not affecting the operation of the grab handle 2. When blasting is to be carried out, the splash guard 6 is pulled up again.

[0033] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the buffer 5 includes a bottom plate 501 fixedly connected to the top of the fairing 4 and a top plate 502 fixedly connected to the bottom of the cab 3. A spring 503 is connected between the bottom plate 501 and the top plate 502, and a damping telescopic rod 504 located in the middle of the spring 503 is connected between the bottom plate 501 and the top plate 502.

[0034] In this embodiment, as Figures 1-6 As shown, the working process of the central rotating body protection and guiding device provided in this embodiment is as follows:

[0035] The deflector 4 reverses the flow of shock waves and rocks, greatly reducing the deformation and equipment damage caused by blasting shock waves and rock impacts on the rock grabber; the splash guard 6 increases the shielding area and blocks the upward flow of rocks guided by the deflector 4, further protecting the rock grabber; the buffer 5 buffers the impact and reduces its intensity.

[0036] The splash guard 6 and the deflector 4 are rotatably connected by a hinge 12. A pull rope 13 is connected between the top of the splash guard 6 and the outer wall of the cab 3. Therefore, when not in use, the pull rope 13 is released and the splash guard 6 automatically stands upright under the action of gravity, thereby reducing the space occupied and not affecting the operation of the grab handle 2. When blasting is carried out, the splash guard 6 is pulled up again.

[0037] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
