As shown in the first support rod 1 and the second support rod 4 are provided with the first ground insertion rod 5, so that after the protective area is determined, the first ground insertion rod 5 can be vertically inserted into the ground to fix the whole protective device. In order to avoid the impact force generated during blasting from affecting the stability of the first ground insertion rod 5, a plurality of second ground insertion rods 12 are movably arranged in the first ground insertion rod 5, so that after the first ground insertion rod 5 is inserted into the ground, the second ground insertion rods 12 arranged in the first ground insertion rod 5 can be extended out and inserted into the ground transversely by rotating the second rotating rod 14, the stability of the first ground insertion rod 5 in the ground is improved, and the situation that the impact wave generated during blasting shakes out the first ground insertion rod 5 to cancel the protection of the slope by the protective nets 3 is avoided, and the installation strength of the slope blasting protection device is improved.

[0024] The width of the drill bit 10 is greater than the width of the first ground insertion rod 5, the two sides of one end of the first ground insertion rod 5 are slidably arranged in the inner wall of the drill bit 10, the bottom end of the rotating nut 8 extends into the first ground insertion rod 5, the bottom end of the rotating nut 8 is connected with one end of the second rotating rod 14, the outer side of the second rotating rod 14 is provided with a gear, the gear on the outer side of the second rotating rod 14 is meshed and connected with the gear on one end of the lead screw 13, the bottom end of the compression spring 16 is connected with the top end of the first ground insertion rod 5, the second ground insertion rod 12 is threadedly connected with the lead screw 13, one end of the first ground insertion rod 5 is provided with the knocking plate 7, and the inside of the knocking plate 7 is provided with the rotating nut 8.

[0025] Specifically, as shown in Figure 1 , Figure 2 and Figure 4 , since the width of the drill bit 10 is greater than the width of the first ground insertion rod 5, when the first ground insertion rod 5 is inserted into the ground, the drill bit 10 arranged at one end of the first ground insertion rod 5 can provide a channel for the first ground insertion rod 5, so that the situation that the perforations 15 on the outer side of the first ground insertion rod 5 are blocked by the soil is avoided, and the second ground insertion rod 12 can be stably extended out of the first ground insertion rod 5.

At the same time, when installed and used, the protective net 3 can be prevented from being in a tight state through the action of the reset spring 17. When blasting, the protective net 3 with certain ductility can better protect the flying stones with impact force and avoid the breaking of the protective net 3 due to strong impact force. The reinforcing rib 2 and the connecting rod 18 can provide better support and protection for the protective net 3 as a whole.

[0028] Working principle: when used, the protective area of the protective net 3 on the slope blasting can be expanded by pulling the distance between the first supporting rod 1 and the second supporting rod 4, the size of the protective surface can be self-adaptively adjusted according to the on-site construction area, and the flexibility of the protective device when used is improved.
