[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-6 , the present invention provides a technical solution: a blasting aftershock buffer composite plate with a force unloading function, including a support bottom plate 1, an installation outer frame 2, a first buffer frame 3, a first filter screen 4, a second buffer frame 5, a second filter screen 6, a connecting frame 7, a positioning column 8, a limit clamping block 9, a dust-proof cloth 10, a linkage gear 11, a first magnet 12, a piston column 13, a second magnet 14 and a sealing airbag 15.

A positioning hole is provided on the surface of the connecting frame 7, and the positioning hole of the connecting frame 7 is penetrated by the positioning column 8. A groove is provided on the upper surface of the positioning column 8. When using this device, first, large flying stones are intercepted by the first filter screen 4 on the surface of the first buffer frame 3, so that the first buffer frame 3 slides relative to the installation outer frame 2 to compress the spring for buffering.

[0031] A groove is provided on the front surface of the installation outer frame 2, and the inner wall of the groove of the installation outer frame 2 is slidably connected with the first buffer frame 3. The limit clamping block 9 and the connecting frame 7 are slidably connected, and a spring is connected between the limit clamping block 9 and the connecting frame 7. The limit clamping block 9 and the positioning column 8 are snap-connected. Tooth blocks are provided on the outer surface of the first buffer frame 3, and tooth blocks are provided on the outer surface of the second buffer frame 5. Both the second buffer frame 5 and the first buffer frame 3 are meshed with the linkage gear 11 through the tooth blocks.

[0032] An opening is provided on the surface of the first buffer frame 3, and a first filter screen 4 is connected to the inner wall of the opening of the first buffer frame 3. An opening is provided on the surface of the installation outer frame 2, and a second buffer frame 5 is slidably connected to the inner wall of the opening of the installation outer frame 2. An opening is provided on the surface of the second buffer frame 5, and a second filter screen 6 is connected to the inner wall of the opening of the second buffer frame 5. A first magnet 12 is embeddedly installed on the lower surface of the positioning post 8. A groove is provided on the inner wall of the positioning hole of the connecting frame 7, and a piston post 13 is slidably connected to the inner wall of the groove of the connecting frame 7. A second magnet 14 is fixed to the upper end of the piston post 13. A sealing airbag 15 is fixedly connected to the outer surface of the connecting frame 7. When the device works, the positioning post 8 is inserted into the positioning hole of the connecting frame 7 for easy disassembly and assembly, and the positioning post 8 is fixed by the limit block 9 being snapped into the groove of the positioning post 8, improving the stability.

Two limit blocks 9 are slidably connected to the upper surface of the connecting frame 7. An opening is provided on the surface of the connecting frame 7, and a dust-proof cloth 10 is connected to the inner wall of the opening of the connecting frame 7. A linkage gear 11 is rotatably connected inside the installation outer frame 2. The opposite ends of the first magnet 12 and the second magnet 14 have the same magnetic poles. A spring is connected between the piston post 13 and the connecting frame 7. The piston post 13 is communicated with the cavity of the sealing airbag 15. The sealing airbag 15 is of an annular design. After the second magnet 14 is repelled, it drives the piston post 13 to slide, so that the piston post 13 pushes air into the sealing airbag 15, causing the sealing airbag 15 to expand and fit against the inner wall of the installation outer frame 2, thereby improving the sealing performance, increasing the dust interception effect of the device, and improving the practicability.

[0034] Working principle: When using the blasting aftershock buffer composite plate with a force unloading function, first, the installation outer frame 2 is fixedly installed through the support bottom plate 1, so that the flying stones are initially intercepted by the first filter screen 4, causing the first filter screen 4 to drive the first buffer frame 3 to slide, and the first buffer frame 3 drives the second buffer frame 5 to move in the opposite direction through the linkage gear 11, so that the second buffer frame 5 drives the second filter screen 6 to intercept the remaining flying stones, thereby improving the buffering performance. The installation outer frame 2 and the connecting frame 7 are connected by inserting the positioning post 8 into the positioning hole of the connecting frame 7, and the positioning post 8 is fixed by the limit block 9. Dust prevention is carried out through the dust-proof cloth 10. During work, the positioning post 8 drives the first magnet 12 to repel the second magnet 14, causing the second magnet 14 to drive the piston post 13 to move and push air into the sealing airbag 15, causing the sealing airbag 15 to expand and seal, increasing the overall practicability.
