Description

Technical Field

[0001] This utility model relates to the field of security monitoring technology, specifically a device for clearing blast holes. Background Technology

[0002] Nowadays, in blasting operations of civil engineering projects such as tunnel engineering, water conservancy projects, and road construction, blasting holes are prone to blockage due to various reasons. Rock chips and soil generated during drilling will accumulate in the hole, and if they are not cleared in time, it will affect the progress and quality of the project.

[0003] In existing technologies, most blast hole clearing devices use a motor to drive a drill bit to rotate, breaking up the blockage while the drill bit's spiral structure acts as a transport mechanism. After transporting the blockage to the hole opening, it still needs to be manually removed, and the drill bit needs to be pushed and pulled by the user to move it forward and backward. This is not convenient to use. Therefore, a blast hole clearing device is proposed to solve the problems mentioned above. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figures 1-5 A blast hole clearing device in this embodiment includes a housing 1 and a collection bin 15. A rotary motor 2 is slidably installed inside the housing 1. A rotary shaft 3 is fixedly connected to the output end of the rotary motor 2. A portion of the outer side of the rotary shaft 3 is provided with an external thread. A hollow spiral column 4 is fixedly installed at the upper end of the housing 1. The rotary shaft 3 and the hollow spiral column 4 are threadedly engaged. At least two sliding brackets 6 are fixedly installed on the outer side of the rotary motor 2. At least two sliding grooves 5 are opened on the inner wall of the housing 1. One end of the sliding bracket 6 is slidably installed inside the sliding groove 5. A spiral conveying drill bit 16 is fixedly installed at the lower end of the collection bin 15. The spiral conveying drill bit 16 is located inside the collection bin 15. A slag discharge door 18 is movably installed at the lower end of the collection bin 15. The slag discharge door 18 is installed through the collection bin 15.

[0025] When the rotary motor 2 is started, the rotary shaft 3 connected to the output end begins to rotate. The rotating shaft 3 moves inside the hollow spiral column 4 that is threaded with it, thereby driving the rotary motor 2 to move. The movement of the rotary motor 2 is affected by the sliding bracket 6, so it moves back and forth along the slide groove 5, realizing the synchronous movement of the rotary shaft 3 and the rotary motor 2, as well as the rotation of the rotary shaft 3. This achieves the function of rotation and back and forth movement. When the spiral conveying drill bit 16 located inside the collection chamber 15 rotates, its special spiral structure will drive the broken soil from the drill bit to move. The soil moves into the collection chamber 15 along with the spiral structure. The collected soil is discharged through the soil discharge door 18 and the reverse rotation of the spiral conveying drill bit 16, avoiding the need for manual removal of soil from the borehole opening.

[0026] An extrusion frustum 13 is fixedly installed on the outer side of the rotating shaft 3. The extrusion frustum 13 is located on the part of the rotating shaft 3 without external threads. At least two hollow columns 8 are fixedly installed on the outer side of the housing 1. The hollow columns 8 pass through the housing 1 and extend into the interior of the housing 1. A spring 9 is movably installed inside the hollow column 8. One end of the spring 9 is fixedly connected to an annular extrusion disc 12. The annular extrusion disc 12 is located inside the housing 1. The other end of the spring 9 is fixedly connected to a mounting column 10. A fixing disc 11 is installed inside the mounting column 10. The fixing disc 11 extends to the outside of the mounting column 10 and is threadedly engaged with the mounting column 10.

[0027] When the rotating shaft 3 starts to move, the extrusion platform 13 on the rotating shaft 3 will also move. The structure of the extrusion platform 13, which is larger in the front and smaller in the back, will exert a squeezing effect on the annular extrusion plate 12 as the extrusion platform 13 moves forward, pushing the annular extrusion plate 12 to move out of the box 1. At this time, the spring 9, the mounting column 10 and the fixed plate 11 connected to the annular extrusion plate 12 will also move in the same direction. As they move, they will exert a squeezing force on the blast hole, which will have a fixing effect and reduce the shaking generated by the entire device during operation. The annular extrusion plate 12 inside the box 1 and the mounting column 10 outside the box 1 will limit the spring 9 to prevent the spring 9 from falling out of the box 1. The fixed plate 11, which is threaded into the mounting column 10, can be replaced with different lengths to adapt to blast holes of different sizes.

[0028] A mounting plate 7 is fixedly installed on the upper end of the rotating shaft 3. The mounting plate 7 is located outside the box 1. At least two spiral fixing rods 17 are fixedly installed on the lower end of the collection bin 15. The spiral fixing rods 17 are threadedly engaged with the mounting plate 7.

[0029] When the rotating shaft 3 rotates and moves, the mounting plate 7 fixed to it and the collection chamber 15 threaded to the mounting plate 7 will also rotate and move synchronously. When facing blasting holes of different sizes, the spiral hole of the mounting plate 7 can select a spiral conveying drill bit 16 of different sizes to be spirally fixed through the collection chamber 15 to complete the size change.

[0030] Stop buttons 14 are fixedly installed on both opposite sides of the inner wall of the slide 5, and there are at least two stop buttons 14.

[0031] When the rotary motor 2 moves a certain distance, the sliding bracket 6 will move to the edge of the slide 5 and start to press the stop button 14, thus stopping the rotation of the rotary motor 2, preventing the situation where the rotary motor 2 keeps moving forward and the crushing frustum 13 collides with the box 1 or the rotary motor 2 collides with the box 1.

[0032] The stop button 14 stops the rotation of the rotary motor 2 and the structure of the slag discharge door 18 are common technologies. As long as they can achieve their beneficial effects, they can be implemented. They are common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
