[0027] Specifically, a plurality of support frames 12 are fixedly connected to the barrier body 113.

[0028] Specifically, the barrier assembly 11 further includes a protection box 115, which is fixedly connected to the barrier body 113 and away from one side of the support frame 12, and a hidden groove 116 is formed in the bottom of the protection box 115.

[0029] Specifically, the protection assembly 2 includes a protection plate 21, a plurality of shaft sleeves 22 are fixedly connected to the protection plate 21, the protection plate 21 is rotatably connected to the outside of the plurality of pivots 114 through the plurality of shaft sleeves 22, a fixed block 23 is further fixedly connected to the protection plate 21, and a positioning hole is formed in the fixed block 23.

[0030] From the above, in use, first of all, the device is firmly fixed in the designated position by using the ground nail 112, ensuring its stability during the operation, the barrier body 113 as the first line of defense, can effectively block the front splashing ore, provide preliminary safety protection for the operating personnel, when the need to protect the ore above, release the positioning assembly 13 on the limiting of the protective plate 21, then, by pulling down the protective plate 21, with the help of the shaft sleeve 22 and the shaft 114, the protective plate 21 can be smoothly and smoothly turned down, until the protective plate 21 stably rests on the support frame 12, at this time, the support frame 12 plays a key supporting role, and the protective plate 21 forms a stable and efficient protective structure, thereby blocking the ore above, the whole operation process is simple and fast, without complex tools and steps, greatly improving the work efficiency.

[0031] Example two: this example is basically the same as the last example, the difference is that the positioning assembly 13 includes a positioning rod 131 slidingly connected to the protective box 115, one end of the positioning rod 131 extends to the outside of the protective box 115, the other end of the positioning rod 131 extends into the hidden groove 116 and is fixedly connected with the handle 132, the outside of the positioning rod 131 is fixedly connected with the limiting ring 133, the outside of the positioning rod 131 and the bottom of the limiting ring 133 are sleeved with the spring 134, the spring 134 can drive the limiting ring 133 to make the positioning rod 131 embedded in the positioning hole.

[0032] From the above, when it is necessary to turn over the protective assembly 2 to protect the top, only need to pull down the handle 132, this action will drive the positioning rod 131 to move downward, thereby making the limiting ring 133 compress the spring 134, as the positioning rod 131 gradually leaves the positioning hole on the fixed block 23, the limiting of the protective assembly 2 is released, at this time, the protective assembly 2 can be turned over to the support frame 12, when it is not necessary to protect the top, only need to turn over the protective assembly 2 upward, and release the handle 132, at this time, the spring 134 will use its restoring force to push the limiting ring 133 to move upward, thereby driving the positioning rod 131 to re-embed in the positioning hole on the fixed block 23, thereby stably fixing the protective plate 21 on the barrier body 113, increasing the protection height, the design of the hidden groove 116 greatly enhances the safety of the device, it can effectively prevent the external falling stone from accidentally hitting the handle 132, thereby avoiding the positioning rod 131 from accidentally leaving the positioning hole due to external impact, ensuring that the protective assembly 2 can always remain stable when it is not necessary to turn over.

[0033] Application process:

[0034] Installation and preliminary protection:

[0035] The base 111 of the mine blasting safety isolation screen is fixed in the designated position by using the ground nail 112, ensuring the stability of the screen.

[0036] The barrier body 113 effectively blocks the front splashed ore as the first line of defense, and protects the operating personnel safety.

[0037] Opening of the top protection:

[0038] When the protection of the ore above needs to be increased, the positioning assembly 13 is operated.

[0039] Pull down the handle 132 to drive the positioning rod 131 to move downward, and at the same time, the limiting ring 133 compresses the spring 134, so that the positioning rod 131 is out of the positioning hole of the fixed block 23, and the limiting of the protection assembly 2 is released.

[0040] With the cooperation of the shaft sleeve 22 and the rotating shaft 114, the protection plate 21 is stably turned over to the support frame 12 to form a stable top protection structure.

[0041] Closing of the top protection:

[0042] When the top protection is not needed, the protection plate 21 is turned upward to the original position.

[0043] Loosen the handle 132, the spring 134 restores the deformation, pushes the limiting ring 133 and the positioning rod 131 to re-embed into the positioning hole of the fixed block 23, fixes the protection plate 21, and increases the height of the protection.

[0044] Safety design:

[0045] The design of the hidden groove 116 prevents the handle 132 from being accidentally hit by external falling stones, avoids the positioning rod 131 from being accidentally out of the positioning hole, and ensures the stability of the protection assembly 2.
