[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-3 A safety protection device for blasting in iron ore mining includes a base plate 1, two fixing blocks 12, a rotating shaft 13, a hollow protective plate 8, a groove 3, two through slots 10, a first adjustment mechanism, and a second adjustment mechanism. The two fixing blocks 12 are fixedly installed on the top of the base plate 1. The rotating shaft 13 is rotatably connected between the two fixing blocks 12. The hollow protective plate 8 is fixedly connected to the outer wall of the rotating shaft 13. The groove 3 is opened on the top of the base plate 1. The two through slots 10 are respectively set on the two side walls of the hollow protective plate 8 and are connected to the interior of the hollow protective plate 8. The base plate 1 is T-shaped, and three conical rods 2 are provided at the bottom of the base plate 1.

[0018] The first adjustment mechanism includes a first threaded rod 5, a first movable block 6, a first connecting rod 7, and a first knob 4. The first threaded rod 5 is rotatably connected between the inner walls of both ends of the groove 3. The first movable block 6 is threaded onto the first threaded rod 5. One end of the first connecting rod 7 is rotatably connected to the top of the first movable block 6. The other end of the first threaded rod 5 is rotatably connected to the hollow protective plate 8. One end of the first threaded rod 5 passes through the inner wall of one end of the groove 3 and extends outward. The first knob 4 is fixedly installed on one end of the first threaded rod 5. The first movable block 6 is slidably connected to both inner walls of the groove 3, restricting the circumferential rotation of the first movable block 6 and ensuring that it can only move smoothly along the axial direction of the first threaded rod 5.

[0019] The second adjustment mechanism includes a second threaded rod 16, a second knob 9, a second movable block 19, two adjusting plates 11, and two second connecting rods 18. The second threaded rod 16 is rotatably connected between the inner top and inner bottom of the hollow protective plate 8. The second movable block 19 is threaded onto the second threaded rod 16. The two adjusting plates 11 are located on both sides of the second threaded rod 16. One end of each of the two second connecting rods 18 is rotatably connected to the outer walls of both sides of the second movable block 19, and the other end of each of the two second connecting rods 18 is rotatably connected to the two adjusting plates 11. One end of the second threaded rod 16 passes through the inner top of the hollow protective plate 8 and extends outward. The second knob 9 is fixedly connected to one end of the second threaded rod 16. The inner top and inner bottom of the hollow protective plate 8 are connected... Two guide rods 17 are fixedly connected. The second moving block 19 is slidably fitted on the two guide rods 17 to guide the movement of the second moving block 19 and prevent it from rotating with the second threaded rod 16. The two adjusting plates 11 are respectively located in the two through slots 10 and are adapted to the two through slots 10 respectively. Two sliding grooves 14 are opened on the inner top and inner bottom of the hollow protective plate 8. Sliding blocks 15 are fixedly installed on the top and bottom of the two adjusting plates 11 and cooperate with the sliding grooves 14 to ensure that the adjusting plates 11 can extend and retract smoothly along the predetermined trajectory. The four sliding blocks 15 are respectively located in the four sliding grooves 14 and are slidably connected to the four sliding grooves 14 respectively. They work together to constrain the adjusting plates 11 so that they can only move in a straight line and will not deviate or get stuck.

[0020] In use, the entire device is fixed to the ground by the base plate 1 and the three conical rods 2 at its bottom. The operator first rotates the first knob 4, which drives the first threaded rod 5 to rotate, and drives the first moving block 6, which is threaded and fitted on the first threaded rod 5, to move horizontally in the groove 3. The movement of the first moving block 6 pushes the hollow protective plate 8 to rotate around the pivot 13 fixed between the two fixed blocks 12 through the first connecting rod 7, thereby adjusting the tilt angle of the protective plate. Then, the operator rotates the second knob 9, which drives the second threaded rod 16 to rotate, so that the second moving block 19, which is threaded and fitted on the second threaded rod 16, moves along the two guide rods 17. The movement of the second moving block 19 pushes the two adjusting plates 11 to slide in the through grooves 10 on both sides of the hollow protective plate 8 through the two second connecting rods 18. The sliding block 15 fixed on the adjusting plate 11 is guided in the sliding groove 14 to ensure that the adjusting plate 11 extends or retracts smoothly, and finally achieves dual adjustment of the protective angle and the protective area.
