[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-6 , the present utility model provides a technical solution: a blasting anti-gravel device based on flexible interception, including a metal plate 1. The metal plate 1 is designed to be concave and inclined, and a side support frame 2 is fixedly installed on the outer surface of one side of the metal plate 1. A bottom plate slide bar 6 is provided on the outer surface of one side of the metal plate 1, and fixing ears are respectively provided at both ends of the bottom plate slide bar 6. A fixed insertion rod 17 penetrates through the fixing ear on the outer surface of the bottom plate slide bar 6, and the fixed insertion rod 17 is inserted into the ground. An elastic mechanism is provided on one side of the metal plate 1, and the elastic mechanism intercepts the splashing stones to reduce the impact force received by the metal plate 1.

[0030] The flying gravel is bounced off by the inclined design of the metal plate 1 to reduce the impact force of the gravel on the metal plate 1. At the same time, the bottom plate slide rod 6 is fixed by the fixed insertion rod 17 and fixed to the ground.

[0031] The elastic mechanism includes: a wire mesh 3. On the outer surface of the side of the wire mesh 3 close to the metal plate 1, a bottom layer tensile retaining cloth 4 is fixedly installed. And a tension spring 5 is installed through the outer surface of the bottom layer tensile retaining cloth 4. And the tension spring 5 passes through the outer surface of the wire mesh 3. One end of the tension spring 5 away from the wire mesh 3 and the bottom layer tensile retaining cloth 4 passes through the outer surface of the side support frame 2. And the side support frame 2 is concentrically designed with the wire mesh 3 and the bottom layer tensile retaining cloth 4.

[0032] After blasting, the gravel will be thrown into the air, and some of the gravel will fly directly out and hit the side support frame 2. The wire mesh 3 inside the side support frame 2 will intercept and block the gravel. The bottom layer tensile retaining cloth 4 on one side of the wire mesh 3 will enhance the tensile property of the wire mesh 3 to prevent the gravel impact force from being too high to penetrate the wire mesh 3 and the bottom layer tensile retaining cloth 4. At the same time, the tension spring 5 can reduce the impact force of the gravel on the wire mesh 3 and the bottom layer tensile retaining cloth 4, slow down the impact of the gravel on the metal plate 1, intercept the gravel and protect the operators behind the device.

[0033] A clamping mechanism is arranged between the metal plate 1 and the bottom plate slide rod 6. The metal plate 1 is fixedly supported by the clamping mechanism to make the metal plate 1 stand up for convenient erection of the device. The clamping mechanism includes: a sliding resistance rod 10. The sliding resistance rod 10 is slidably installed inside the bottom plate slide rod 6. And a spring 8 is arranged between the bottom plate slide rod 6 and the sliding resistance rod 10. And a side support rod 12 is rotatably installed on the outer surface of the sliding resistance rod 10. A buckle rod 13 is fixedly installed on the outer surface of the side of the metal plate 1 close to the sliding resistance rod 10. And the buckle rod 13 is engaged with one end of the side support rod 12.

[0034] When the device needs to be installed, the side support rod 12 can be pulled to drive the sliding resistance rod 10 to move, so that the buckle fixing ear 9 is disengaged from the moving fixing block 11, and the metal plate 1 can be flipped open. The metal plate 1 is limited by the sliding block 7. Then the side support rod 12 is inserted into the buckle rod 13. Through the thrust of the spring 8, the side support rod 12 and the buckle rod 13 are engaged to form a stable triangular support. Then the fixed insertion rod 17 is inserted into the bottom plate slide rod 6 and fixed to the ground. At the same time, when the gravel impacts the metal plate 1 during blasting, it will also push the sliding block 7 and the sliding resistance rod 10 to move, and the spring 8 will push the sliding resistance rod 10 back, slowing down the force of the gravel impacting the metal plate 1, enabling the anti-gravel device to perform secondary buffering to reduce the impact force, and at the same time being convenient for erection and storage.

[0035] On one side surface of the metal plate 1, a buckle fixing ear 9 is fixedly installed, and a sliding block 7 is rotatably installed inside the buckle fixing ear 9.

A moving fixing block 11 is fixedly installed on the outer surface of the sliding resisting rod 10, and the moving fixing block 11 is engaged with the groove of the buckle fixing ear 9. A roller 18 is fixedly installed at one end of the bottom plate slide bar 6 close to the side support frame 2.

[0036] After the metal plate 1 is flipped, the buckle fixing ear 9 rotates accordingly. The spring 8 pushes the sliding resisting rod 10, enabling the sliding resisting rod 10 to drive the moving fixing block 11 to move, so that the moving fixing block 11 is pushed into the groove at one end of the buckle fixing ear 9. Through the engagement between the buckle fixing ear 9 and the moving fixing block 11, the bottom plate slide bar 6 and the metal plate 1 are fixed.

[0037] At one end of the metal plate 1 away from the bottom plate slide bar 6, a sliding and flipping mechanism is provided, which facilitates the erection of the anti-gravel device through the sliding and flipping mechanism, improving the top protection ability of the device.

[0038] By pulling the rotating top plate 15, the sliding rod 14 can be driven to move together. Then, the rotating top plate 15 is flipped so that the rotating top plate 15 is aligned with the sliding rod 14. After that, the rotating top plate 15 and the sliding rod 14 can be pushed to insert the sliding rod 14 and the rotating top plate 15 into the top of the metal plate 1, facilitating the erection and installation of the rotating top plate 15 and enhancing the top protection ability of the anti-gravel device.

[0039] The sliding and flipping mechanism includes: a sliding rod 14. The sliding rod 14 is slidably installed at one end of the metal plate 1 away from the side support rod 12. A rotating top plate 15 is rotatably installed between the sliding rods 14. Moreover, the rotating top plate 15 is inclined. One end of the rotating top plate 15 is slidably connected to the metal plate 1, and the metal plate 1 is engaged with the rotating top plate 15.

A buckle fixing block 16 is fixedly installed on the outer surface of the rotating top plate 15, and the buckle fixing block 16 is engaged with the side surface of one end of the side support rod 12.

[0040] After use, the side support rod 12 can be pulled out of the buckle rod 13. Then, the metal plate 1 is rotated to fold the bottom plate slide bar 6. The spring 8 pushes the sliding resisting rod 10 to engage the moving fixing block 11 with the buckle fixing ear 9, fixing the metal plate 1 and the bottom plate slide bar 6. Then, the rotating top plate 15 together with the sliding rod 14 is pulled out of the metal plate 1, and the rotating top plate 15 is rotated so that one end of the side support rod 12 is caught in the buckle fixing block 16, cooperating with the thrust of the spring 8 to fix the rotating top plate 15 at the same time. After that, the rotating top plate 15 can be pulled to facilitate the movement of the gravel protection device in cooperation with the roller 18.

[0041] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
