[0027] The protective mechanism includes an annular plate 4 fixedly installed at the bottom of the mounting plate 1, a support plate 5 slidably installed on the inner side wall of the annular plate 4, multiple support rods 6 fixedly installed at the bottom of the support plate 5, an electric push rod 7 passing through and fixedly installed on the mounting plate 1, the bottom of the electric push rod 7 being fixedly connected to the top of the support plate 5, and a dust removal component on the annular plate 4.

[0028] Depend on Figure 2 and Figure 3 It can be seen that by placing the mounting plate 1 above the blast hole, the cleaning box 3 is located directly above the blast hole. The mounting plate 1 is supported by the support rod 6, so that a gap is formed between the annular plate 4 and the ground. The support plate 5 is moved up or down by the electric push rod 7, so that the height between the bottom of the support rod 6 and the bottom of the annular plate 4 is lowered or raised, thereby adjusting the size of the gap.

[0029] As can be seen from the above, the lifting component drives the ventilation pipe 2 to move up and down, thereby causing the cleaning box 3 to move up and down inside the blast hole. This facilitates the cleaning box 3 to clean different positions within the blast hole. Through the coordinated use of the air inlet component and the adjustment component, the air outlet hole rotates, allowing the high-pressure air to be blown evenly to different positions within the blast hole, increasing the cleaning range of the high-pressure air and thus improving the cleaning effect. The high-pressure air carries the fragments and dust upwards and then flows outwards through the gaps. During the flow, the dust removal component sprays the high-pressure air to remove dust, preventing dust from being stirred up and protecting the working environment from pollution.
