Description

Borehole charging structure for rockfill dam blasting mining Technical Field

[0001] This application relates to the field of engineering blasting technology, and in particular to the blast hole charging structure for rockfill dam grade batching blasting mining. Background Technology

[0002] A rockfill dam is a type of earth-rock dam constructed primarily of rock fill with impermeable walls. Its advantages include the ability to fully utilize local natural materials, adaptability to various geological conditions, relatively simple construction methods, and good seismic resistance. Extensive blasting is employed during the extraction of dam fill material to obtain a large quantity of usable material.

[0003] Currently, traditional borehole charging structures require the cleaning of rock powder inside the borehole before use. This cleaning process requires manual cleaning by staff, resulting in a waste of human resources. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a blast hole charging structure for rockfill dam graded batching blasting mining, which overcomes the deficiencies of existing technologies and aims to solve the problems in the background technology.

[0005] To achieve the above objectives, this application adopts the following technical solution: a blasting borehole charging structure for rockfill dam grade batching and blasting, comprising a base, a support mechanism on one side of the base, a charging box fixedly connected to the top of the base, a discharge pipe fixedly connected to the bottom of the charging box, a vibration mechanism on the exterior of the charging box, a compaction mechanism inside the charging box, a height adjustment mechanism on one side of the charging box, a moving plate inside the height adjustment mechanism, a cleaning mechanism at the bottom of the moving plate, the cleaning mechanism comprising a second motor, the second motor fixedly connected to the moving plate, a drive gear fixedly connected to the output end of the second motor, a driven gear meshing on one side of the drive gear, an installation rod fixedly connected inside the driven gear, the installation rod rotatably connected to the moving plate, a conveying pipe rotatably connected to the top of the installation rod, and a brush fixedly connected to the surface of the installation rod.

[0006] In a preferred embodiment, the support mechanism includes a fixed block, which is fixedly connected to the base. A rotating rod is threadedly connected to the inside of the fixed block, and a support block is rotatably connected to the bottom of the rotating rod.

[0007] By adopting the above technical solution, the rotating rod is limited by the fixed block, and then the rotating rod is rotated to make the support block at the bottom of the rotating rod touch the ground, thereby supporting and positioning the base. This can better support and position the base.

[0008] In a preferred embodiment, the vibration mechanism includes a vibration motor, which is fixedly connected to the medicine box. A vibration block is fixedly connected to the vibration end of the vibration motor, and a spring is fixedly connected to the surface of the vibration block, with the spring abutting against the surface of the medicine box.

[0009] By adopting the above technical solution, the vibration end of the vibration motor drives the vibration block to vibrate, and the vibration block drives the spring to vibrate. The spring then transmits the vibration to the medicine box to make the medicine box vibrate, preventing the material inside the medicine box from clogging. This can better make the medicine box vibrate and prevent the material inside the medicine box from clogging.

[0010] In a preferred embodiment, the compaction mechanism includes a mounting frame, which is fixedly connected to the loading box. A pneumatic push rod is fixedly connected to the bottom of the mounting frame, and a pressure plate is fixedly connected to the bottom of the pneumatic push rod.

[0011] By adopting the above technical solution, the pneumatic push rod is fixed by the mounting bracket, and then the extension and retraction end of the pneumatic push rod drives the pressure plate to move. The pressure plate then separates from the charge box and enters the borehole to compact the explosive charge inside the borehole, which can better compact the explosive charge inside the borehole.

[0012] In a preferred embodiment, the height adjustment mechanism includes a fixed frame, which is fixedly connected to a base. A motor is fixedly connected to the top of the fixed frame, and a threaded rod is fixedly connected to the output end of the motor. The threaded rod is rotatably connected to the fixed frame, and the threaded rod is threadedly connected to a movable plate. The movable plate is slidably connected to the fixed frame.

[0013] By adopting the above technical solution, the motor is fixed by the fixed frame, and the output end of the motor drives the threaded rod to rotate. The rotation of the threaded rod causes the moving plate to move inside the fixed frame, which can better enable the moving plate to move inside the fixed frame.

[0014] In a preferred embodiment, the base is equipped with four casters, which are symmetrically distributed on the bottom of the base.

[0015] By adopting the above technical solution, four casters are installed at the bottom of the base, and the casters roll along a designated route to move the base, which can make the base move more effectively.

[0016] In a preferred embodiment, a valve is fixedly connected to the outer surface of the discharge pipe, and a top cover is slidably connected to the top of the medicine box.

[0017] By adopting the above technical solution, a valve is fixedly connected to the outside of the discharge pipe, and the flow rate of the material inside the discharge pipe is controlled by the valve, which can better control the flow rate of the material inside the discharge pipe.

[0018] The beneficial effects of this application are:

[0019] 1. The blast hole charging structure for rockfill dam blasting mining utilizes a brush, mounting rod, driven gear, driving gear, motor II, and delivery pipe. The motor II's output rotates, driving the driving gear, which in turn meshes with the driven gear, causing it to rotate. This rotation of the driven gear then rotates the mounting rod, which in turn drives the brush to clean the inner wall of the blast hole. A high-pressure gas pump connected to the delivery pipe then delivers high-pressure gas into the blast hole, blowing out the rock powder. This design avoids the need for manual cleaning of the blast hole interior, which is a waste of manpower in traditional blast hole charging structures, thus improving practicality.

[0020] 2. The blast hole charging structure for this rockfill dam blasting and mining method utilizes a mounting frame, pneumatic push rod, and pressure plate. The mounting frame secures the pneumatic push rod, and the extension and retraction of the pneumatic push rod moves the pressure plate, which then detaches from the charging box and enters the blast hole to compact the explosive charge inside. This avoids the problem of traditional blast hole charging structures requiring manual compaction of the explosive charge inside the blast hole, thus improving practicality.

Detailed Implementation

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0027] Referring to Figures 1-2, the blasting hole charging structure for rockfill dam grade batching includes a base 1. A support mechanism 2 is provided on one side of the base 1. The support mechanism 2 includes a fixing block 22, which is fixedly connected to the base 1. A rotating rod 21 is threadedly connected inside the fixing block 22, and a support block 23 is rotatably connected to the bottom of the rotating rod 21. The fixing block 22 limits the rotation rod 21, and the rotation of the rotating rod 21 causes the support block 23 at the bottom of the rotating rod 21 to contact the ground, thus supporting and positioning the base 1. This provides better support and positioning for the base 1.

[0028] Referring to Figures 1-2, a medicine loading box 7 is fixedly connected to the top of the base 1, and a discharge pipe 9 is fixedly connected to the bottom of the medicine loading box 7. A vibration mechanism 4 is provided on the outer surface of the medicine loading box 7. The vibration mechanism 4 includes a vibration motor 41, which is fixedly connected to the medicine loading box 7. A vibration block 42 is fixedly connected to the vibration end of the vibration motor 41, and a spring 43 is fixedly connected to the surface of the vibration block 42. The spring 43 abuts against the surface of the medicine loading box 7. The vibration of the vibration end of the vibration motor 41 drives the vibration block 42 to vibrate, and the vibration of the vibration block 42 drives the spring 43 to vibrate. The spring 43 then transmits the vibration to the medicine loading box 7 to make the medicine loading box 7 vibrate, preventing the material inside the medicine loading box 7 from clogging. This allows the medicine loading box 7 to vibrate more effectively and prevents the material inside the medicine loading box 7 from clogging.

[0029] Referring to Figure 2, the interior of the charge box 7 is equipped with a compaction mechanism 3. The compaction mechanism 3 includes a mounting frame 31, which is fixedly connected to the charge box 7. A pneumatic push rod 32 is fixedly connected to the bottom of the mounting frame 31, and a pressure plate 33 is fixedly connected to the bottom of the pneumatic push rod 32. The pneumatic push rod 32 is fixed by the mounting frame 31, and the extension and retraction of the pneumatic push rod 32 drives the pressure plate 33 to move. The pressure plate 33 then detaches from the charge box 7 and enters the borehole to compact the explosive charge inside the borehole, thus better compacting the explosive charge inside the borehole.

[0030] Referring to Figures 1-3, a height adjustment mechanism 5 is provided on one side of the medicine box 7. The height adjustment mechanism 5 has a movable plate 8 inside. The height adjustment mechanism 5 includes a fixed frame 53, which is fixedly connected to the base 1. A motor 51 is fixedly connected to the top of the fixed frame 53. A threaded rod 52 is fixedly connected to the output end of the motor 51. The threaded rod 52 is rotatably connected to the fixed frame 53 and threadedly connected to the movable plate 8. The movable plate 8 is slidably connected to the fixed frame 53. The motor 51 is fixed by the fixed frame 53, and the output end of the motor 51 rotates to drive the threaded rod 52 to rotate. The rotation of the threaded rod 52 causes the movable plate 8 to move inside the fixed frame 53, which can better enable the movable plate 8 to move inside the fixed frame 53.

[0031] Referring to Figures 3-4, a cleaning mechanism 6 is provided at the bottom of the movable plate 8. The cleaning mechanism 6 includes a second motor 65, which is fixedly connected to the movable plate 8. A drive gear 64 is fixedly connected to the output end of the second motor 65. A driven gear 63 meshes with one side of the drive gear 64. An installation rod 62 is fixedly connected inside the driven gear 63. The installation rod 62 is rotatably connected to the movable plate 8. A conveying pipe 66 is rotatably connected to the top of the installation rod 62. A brush 61 is fixedly connected to the surface of the installation rod 62.

[0032] Referring to Figure 1, four movable wheels 10 are installed on the bottom of the base 1. The four movable wheels 10 are symmetrically distributed on the bottom of the base 1. By installing four movable wheels 10 on the bottom of the base 1, and then having the movable wheels 10 roll along a designated route to drive the base 1 to move, the base 1 can be moved more effectively.

[0033] Referring to Figures 1-2, a valve is fixedly connected to the outer surface of the discharge pipe 9, and a top cover is slidably connected to the top of the medicine box 7. The valve is fixedly connected to the outer surface of the discharge pipe 9, and the flow rate of the material inside the discharge pipe 9 is controlled by the valve, which can better control the flow rate of the material inside the discharge pipe 9.

[0034] Working principle: The base 1 is pushed so that the mounting rod 62 is positioned directly above the blast hole. The fixing frame 53 then secures the motor 51. The output of the motor 51 rotates, driving the threaded rod 52 to rotate. The rotation of the threaded rod 52 causes the moving plate 8 to move inside the fixing frame 53, allowing the brush 61 and mounting rod 62 to enter the blast hole. The output of the motor 65 then rotates, driving the drive gear 64 to rotate. The drive gear 64 meshes with the driven gear 63, causing the driven gear 63 to rotate. The rotation of the driven gear 63 causes the mounting rod 62 to rotate, which in turn drives the brush 61 to rotate, cleaning the inner wall of the blast hole. An external air pump connected to the delivery pipe 66 delivers high-pressure gas into the blast hole, blowing out the rock powder inside. Finally, the rotation of the motor 51 causes the brush 61 and mounting rod 62 to detach from the blast hole. Inside the borehole, the push base 1 positions the discharge pipe 9 directly above the borehole. The fixing block 22 limits the rotation rod 21, and the rotation rod 21 causes the support block 23 at the bottom of the rotation rod 21 to touch the ground, supporting and positioning the base 1. The powder is then poured into the loading box 7. The vibration end of the vibration motor 41 drives the vibration block 42 to vibrate, which in turn drives the spring 43 to vibrate. The spring 43 transmits the vibration to the loading box 7, causing it to vibrate and preventing material blockage inside the loading box 7. The powder enters the borehole through the discharge pipe 9. The mounting bracket 31 fixes the pneumatic push rod 32, and the telescopic end of the pneumatic push rod 32 extends and retracts, causing the pressure plate 33 to move. The pressure plate 33 then detaches from the loading box 7 and enters the borehole to compact the powder inside.
