[0024] The embodiment of the present application provides a flying stone prevention device for blasting engineering, comprising a main rod body 1, abutting component, an elastic support portion 2 and an elastic blocking portion 3. The abutting component is movably arranged on the main rod body 1 along the axial direction of the main rod body 1, the elastic support portion 2 is rotatably connected to the main rod body 1, and the elastic support portion 2 abuts against the abutting component to put the elastic support portion 2 in a bent state. The elastic blocking portion 3 is connected to the elastic support portion 2 and the main rod body 1, and the elastic blocking portion 3 comprises a flexible material.

[0025] The elastic support portion 2 is made of a material capable of generating elastic deformation. For example, the elastic support portion 2 may be made of spring steel.

[0026] The elastic blocking portion 3 has an elastic and soft structure. For example, the elastic blocking portion 3 may be made of rubber.

[0027] The elastic support part 2 can include two states, one is that the elastic support part 2 is against the abutting part, at this time, the elastic support part 2 is in a bent state, so that the elastic blocking part 3 can be straightened, and the elastic blocking part 3 forms a blocking surface, which can block and buffer the flying stones that hit the blocking surface. The other is that the elastic support part 2 and the abutting part are separated, at this time, because the elastic support part 2 is rotatably connected to the main rod body 1, the elastic support part 2 can be stored in the main rod body 1, which is convenient for storage and reduces space occupation.

[0028] The main rod body 1 is used to support the blocking surface formed by the elastic blocking part 3. When performing blasting operations, the blocking surface is set facing the blasting point. The control personnel can be behind the blocking surface so that the blocking surface can block the flying rocks generated by the blasting, thereby improving the safety of blasting.

[0029] The abutting component is movably arranged on the main rod body 1, so that the bending degree of the elastic supporting part 2 can be adjusted as needed, and thus the size of the blocking surface can be adjusted as needed.

[0030] In some embodiments, the main rod body 1 is further provided with a plurality of supporting parts 8 .

[0031] The plurality of support parts 8 are used to support the main pole body 1 so that the main pole body 1 can be stably placed on the ground.

[0032] In some embodiments, the support portion 8 is provided with a first ring body 9 , the main rod body 1 is provided with a second ring body 10 , and the first ring body 9 is passed through the second ring body 10 .

[0033] The first ring body 9 is inserted into the second ring body 10 , so that the support portion 8 is adjustably connected to the main rod body 1 , which facilitates adjusting the position of each support portion 8 to improve the stability of the main rod body 1 .

[0034] Compared with the conventional connection through a rotating shaft, the first ring body 9 and the second ring body 10 cooperate to make the support part 8 rotatably connected to the main rod body 1, which has the advantage of a wider adjustment range.

[0035] In some embodiments, the support portion 8 is provided with a ground nail 12, and the support portion 8 is provided with a connecting hole 14. The ground nail 12 is passed through the connecting hole 14. Along the axial direction of the ground nail 12, two limiting portions 13 are arranged at intervals on the ground nail 12. The support portion 8 is partially arranged between the two limiting portions 13, and the ground nail 12 is loosely matched with the connecting hole 14.

[0036] The ground nails 12 are driven into the ground, which increases the installation stability of the support part 8 and further improves the stability of the main pole body 1 .

[0037] The two limiting portions 13 of the ground nail 12 enable the ground nail 12 to remain connected to the supporting portion 8 .

[0038] The ground nail 12 and the connecting hole 14 are clearance-matched, so that the position of the ground nail 12 relative to the support part 8 can be adjusted, which is convenient for adjusting the direction of the ground nail 12 being driven into the ground according to the terrain, thereby improving the fixing effect of the support part 8.

[0039] In some embodiments, the abutting component includes a ring body 4 , which is sleeved on the main rod body 1 , and the ring body 4 is threadedly connected to the main rod body 1 .

[0040] The ring body 4 is threadedly connected to the main rod body 1 , so that the abutting component is movably connected to the main rod body 1 .

[0041] In some embodiments, the abutment component further includes a first abutment head 5 , which is disposed on the ring body 4 and has a first accommodating portion 11 , and the elastic support portion 2 has a first inserting portion, which is inserted into the first accommodating portion 11 .

[0042] The first inserting portion is inserted into the first accommodating portion 11 , so that the elastic supporting portion 2 can stably abut against the abutting component, thereby reducing the risk of the elastic supporting portion 2 being detached from the abutting component.

[0043] In some embodiments, the abutment component also includes a second abutment head 6, which is movably connected to the ring body 4 along the axial direction of the ring body 4, the first abutment head 5 and the second abutment head 6 are arranged relatively to each other along the axial direction of the ring body 4, the first accommodating portion 11 is arranged on the side of the first abutment head 5 facing the second abutment head 6, the side of the second abutment head 6 facing the first abutment head 5 is provided with a second accommodating portion 7, and the elastic support portion 2 is provided with a second inserting portion, which is inserted into the second accommodating portion 7.

[0044] The second inserting portion is inserted into the second accommodating portion 7, which further improves the connection reliability between the elastic supporting portion 2 and the abutting component.

[0045] Since the second abutment head 6 is movably connected to the ring body 4, the distance between the first abutment head 5 and the second abutment head 6 can be adjusted. When the distance between the first abutment head 5 and the second abutment head 6 becomes smaller, the elastic support portion 2 can be arranged in the first accommodating portion 11 and the second accommodating portion 7 and cannot fall out. Conversely, when the first abutment head 5 and the second abutment head 6 are separated, the first insertion portion can fall out of the first accommodating portion 11, and the second insertion portion can fall out of the second accommodating portion 7.

[0046] In some embodiments, the second abutment head 6 is sleeved on the ring body 4 , and the second abutment head 6 and the ring body 4 are threadedly connected.

[0047] The second abutment head 6 and the ring body 4 are threadedly connected, so that the second abutment head 6 can be movably connected to the ring body 4 .

[0048] In some embodiments, one side of the main rod body 1 is pointed.

[0049] The pointed side of the main rod body 1 is used for inserting into the ground, so that the main rod body 1 can stand stably on the ground. Furthermore, a hammer head can be provided on the other side of the main rod body 1 to facilitate hammering the main rod body 1 to make it inserted into the ground.

[0050] The above embodiments are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made by ordinary technicians in this field to the technical solutions of the present invention should all fall within the protection scope determined by the claims of the present invention.
