[0006] The top of the wire block is equipped with a drilling motor via a mounting base, and the output shaft of the drilling motor is connected to a drill rod via a coupling. One end of the drill rod is connected to the drill bit body via a connecting plate and bolts. The outer periphery of the drill bit body is provided with external spiral cutter teeth, and the bottom of the drill bit body is provided with radial cutter teeth, with hexagonal frustum cutter teeth arranged between the radial cutter teeth.

[0007] By adopting the above technical solutions, the drilling device for open-pit blasting mining enables the drill bit to cut quickly, effectively increasing the drilling rate. It is convenient for drilling holes in high-hardness rocks such as quartzite, and can drill inclined holes on the blasting surface of open-pit mines to meet different usage requirements.

[0008] Specifically, a slide rail is mounted on the top of the support plate by screws, and a slider is provided at the bottom of the wire block and the slider is located inside the slide rail.

[0009] Specifically, an end plate is welded to one end of the top of the bearing plate, and one end of the lead screw is connected to the end plate through a bearing.

[0010] Specifically, a brakeable omnidirectional wheel is bolted to the bottom corner of the base.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] To enable drill bits to cut rapidly in open-pit mine blasting drilling equipment, effectively increasing drilling speed, and facilitating drilling into high-hardness rocks such as quartzite, and to drill inclined holes on the blasting surface of open-pit mines, thus meeting diverse application requirements, such as... Figure 1-3 As shown, the drilling device for blasting mining in open-pit mines according to this utility model includes a base 1, a bearing plate 16, and a drilling motor 9. A supporting vertical plate 17 is welded to the top of the base 1, and the top of the supporting vertical plate 17 is connected to the bearing plate 16 through a damping shaft. A clamping plate 3 is welded to one side of the supporting vertical plate 17, and a rotating block 4 is connected between the clamping plates 3 through a shaft. An electric cylinder 5 is bolted to the top of the rotating block 4. A forward and reverse motor 7 is mounted on one end of the top of the bearing plate 16 through a mounting seat. The output shaft of the forward and reverse motor 7 is connected to a lead screw 10 through a coupling, and a lead screw block 8 is sleeved on the lead screw 10.

[0024] The top of the wire block 8 is mounted with a drilling motor 9 via a mounting base, and the output shaft of the drilling motor 9 is connected to a drill rod 11 via a coupling. One end of the drill rod 11 is connected to a drill bit body 14 via a connecting plate 13 and bolts. The outer periphery of the drill bit body 14 is provided with external spiral cutter teeth 18, and the bottom of the drill bit body 14 is provided with radial cutter teeth 19, and hexagonal frustum cutter teeth 20 are provided between the radial cutter teeth 19.

[0025] When in use, the drilling device for open-pit blasting mining enables the drill bit to cut quickly, effectively increasing the drilling rate. It is suitable for drilling holes in high-hardness rocks such as quartzite and can also be used to drill inclined holes on the blasting surface of open-pit mines to meet different usage requirements.

[0026] For example, such as Figure 1 As shown, the present invention also includes a slide rail 12 mounted on the top of the bearing plate 16 by screws, and a slider provided at the bottom of the wire block 8 and the slider being located inside the slide rail 12.

[0027] During use, the screw block 8 slides back and forth on the screw 10 to improve stability.

[0028] For example, such as Figure 1 As shown, the present invention also includes an end plate 15 welded to one end of the top of the bearing plate 16, and one end of the lead screw 10 is connected to the end plate 15 through a bearing.

[0029] When using it, make the lead screw 10 rotate stably and reduce shaking.

[0030] For example, such as Figure 1 As shown, the present invention also includes a brakeable universal wheel 2 bolted to the bottom corner of the base 1.

[0031] When in use, the brakeable casters 2 make it easy to move the entire drilling equipment to the designated position.

[0032] For example, such as Figure 1 As shown, the present invention also includes movable blocks 6 connected to both ends of the bearing plate 16 via rotating shafts, and the output shaft of the electric cylinder 5 is connected to the movable blocks 6 via screws.

[0033] In use, the electric cylinder 5 drives the bearing plate 16 to rotate between the top of the support vertical plate 17, thereby adjusting the drilling angle of the drill rod 11 and the drill bit body 14.

[0034] When in use, the brakeable universal wheel 2 facilitates the movement of the entire drilling equipment to a designated position. The drill bit body 14 is aligned with the drilling point in the open-pit mine. The drilling motor 9 drives the drill rod 11 and the drill bit body 14 to rotate rapidly, and the forward and reverse motor 7 drives the lead screw 10 to rotate rapidly, so that the lead block 8 slides back and forth on the lead screw 10, thereby aligning with the open-pit mine for drilling, which is convenient for filling with explosives.

[0035] Because the bottom of the drill bit body 14 is equipped with radial cutting teeth 19, hexagonal frustum cutting teeth 20 and external spiral cutting teeth 18, the drill bit can cut quickly, effectively increasing the drilling rate. This makes it easy to drill holes in high-hardness rocks such as quartzite. The electric cylinder 5 drives the bearing plate 16 to rotate between the top of the support vertical plate 17, thereby adjusting the drilling angle of the drill rod 11 and the drill bit body 14, thus drilling inclined holes on the blasting surface of open-pit mines to meet different usage requirements.
