The staff puts the two baffles 1 together and turns the knob 5 to move the connection between connecting rod 1 9 and connecting rod 2 10 into the support base 15, so that the other baffle 1 can be fixed. In this way, the protective device can be quickly assembled and adjusted according to different blasting site environments to adapt to blasting areas of different sizes and terrains, thereby greatly simplifying the installation process and reducing installation time.

[0030] The upper end of the support base 15 is fixedly connected to the motor 17 by a bolt 16, and the output end of the motor 17 is fixedly connected to the threaded rod 2 18, and the threaded sleeve 19 is threadedly connected to the threaded rod 2 18. The baffle 20 is slidably connected in the baffle 1, and a T-shaped slot 22 is provided on the support base 15. The lower end of the baffle 20 is provided with a T-shaped connecting block 21, and the T-shaped connecting block 21 is slidably connected to the T-shaped slot 22. The threaded sleeve 19 is fixedly connected to the baffle 1. The baffle 1 is provided with multiple groups. The fixed block 2 and the sleeve 12 are arranged on the same side of the baffle 1. The support base 15 is rotatably connected to the fixed shell 3 and is arranged at one end close to the fixed block 2. The threaded rod 16 is arranged on the fixed shell 3. The outer side is arranged at one end away from the fixed block 2, the threaded rod 16 and the threaded collar 7 slide in the slide groove 13, and the end at which the connecting rod 19 and the connecting rod 2 10 are connected slides in the fixed groove 14.

At the same time, it can enable the protective device to flexibly respond to various situations, ensure the protection effect, and thus greatly increase safety.

[0031] Working principle: When starting the blasting work, first, the staff slides a baffle 1 and a baffle 2 20 into the T-slot 22 through the T-shaped connecting block 21. At this time, the staff fixes the motor 17 on the support base 15 through the bolt 16. At this time, the staff slides another baffle 1 and a baffle 2 20 into the T-slot 22 through the T-shaped connecting block 21, and continues to slide the other baffle 1, so that the threaded rod 16 provided on one baffle 1 slides into the slide groove 13 provided on the other baffle 1. When the two baffles 1 are fitted together, the staff turns the knob 5 to rotate the rotating rod 4 on the fixed shell 3, and drives the threaded rod 16 to rotate, and drives the threaded collar 7 to move toward the fixed shell 3, and makes the connecting rod 1 9 and the connecting rod 2 10 fold through the connecting block 1 8 and the connecting block 2 11, so that the connection between the connecting rod 1 9 and the connecting rod 2 10 moves into the support base 15, so that the blasting work can be started. Another baffle 1 is fixed, so that the protective device can be quickly assembled and adjusted according to different blasting site environments to adapt to blasting areas of different sizes and terrains, thereby greatly simplifying the installation process and reducing installation time. When high-altitude protection is required, the staff starts the motor 17, drives the threaded rod 2 18 to rotate, drives the threaded sleeve 19 to move upward, and drives the baffle 1 to move upward. Through the T-shaped connection block 21 and the T-shaped slot 22 T-shaped connection, the baffle 1 can be made to rise and slide on the baffle 2 20. The two baffles 1 are fixedly connected by the connecting rod 1 9, the connecting rod 2 10 and the support base 15, which can drive the other baffle 1 to rise and slide on the other baffle 2 20. In this way, it can be adjusted to a suitable height according to the needs of different terrains. At the same time, it can enable the protective device to flexibly respond to various situations, ensure the protection effect, and thus greatly increase safety.
