Description

Technical Field

[0001] The utility model relates to the technical field of mine tunnel blasting engineering, in particular to a dustproof isolation plate for mine tunnel blasting. Background Art

[0002] With the rapid development of urbanization in my country, there are more and more mine blasting projects. Since blasting work is carried out in mine tunnels, workers need to enter the mine. Therefore, the protection requirements for dust generated by blasting are relatively high.

[0003] When blasting, the existing dust-proof isolation panels require workers to hold handheld devices to block the blasting location. After the blasting is completed, the dust will float in the air for a period of time before dissipating, and workers cannot judge through the dust-proof isolation panels. As a result, dust will still fly if the panels are opened too early, and it will take more time to open them too late. In addition, the workers have to hold the devices all the time, which makes it more laborious for the workers. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing dust-proof isolation plate requires workers to hold handheld equipment to block the blasting position during blasting. After the blasting is completed, the dust will float in the air for a period of time before dissipating, and workers cannot judge through the dust-proof isolation plate. As a result, dust will still fly if the plate is opened too early, and it will take more time to open it too late. In addition, the workers have to hold the equipment all the time, which makes them more laborious. A dust-proof isolation plate for mine blasting is proposed.

[0007] Preferably, an air nozzle is fixedly connected to one side surface of the airbag, the outer surface of the airbag is in contact with the inner surface of the mine tunnel, and the observation port and the glass window are both fan-shaped structures.

[0008] Preferably, both ends of the rotating shaft extend to the outside of the baffle, a spring is fixed to one side surface of the rotating rod, one end of the spring away from the rotating rod is fixedly installed on one side surface of the turntable, and one side surface of the scraper is in contact with one side surface of the glass window.

[0009] Preferably, the inner rod is connected to the rotating shaft in a sliding and rotating manner, the limit groove 1 and the limit block 1 are both triangular structures, and the limit groove 1 and the limit block 1 are adapted to each other, a sliding groove is provided on one side of the turntable 3, and the fixed rod is slidably installed in the sliding groove, the limit groove 2 and the limit block 2 are both cross-shaped structures, and the limit groove 2 and the limit block 2 are adapted to each other.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. Through the observation port, the staff can observe the situation after the blasting through the glass window. By turning the adjustment disk, the scraper can be driven to rotate, so that the scraper can scrape the dust on the surface of the glass window, which is more conducive to the staff to observe the situation after the blasting;
