Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, and in particular to a filling machine for mine blasting holes that prevents material blockage. Background Technology

[0002] In mining blasting operations, borehole filling is a crucial step, directly impacting the safety and efficiency of the blasting process. A borehole filling machine designed to prevent clogging has been developed to address this need. It aims to provide a more efficient and reliable solution for borehole filling in mining blasting, optimizing the traditional filling process through a series of innovative designs and improving overall operational efficiency.

[0003] In existing mine blasting borehole packing technologies, common mechanical structures include simple trolley-type or stationary packing equipment. These devices mostly employ manual or semi-automatic methods to transport packing material to the vicinity of the borehole, and then use simple pushing tools to pack the material into the borehole. Their technical principles are primarily based on human pushing or simple mechanical lever principles; the operation process is relatively basic and lacks adaptability to complex working environments and diverse borehole conditions.

[0004] However, traditional filling equipment lacks a flexible and precise adjustment mechanism, making it difficult to accurately adjust the placement of filling materials such as soil inside the blast hole according to the specific location, angle, and shape of different blast holes. This often results in the filling material not being evenly and accurately distributed within the blast hole, which not only affects the quality of the filling but also reduces the accuracy and adaptability of blasting operations, easily leading to poor blasting results or even safety hazards. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a mine blasting borehole filling machine for preventing material blockage. It aims to improve the problem that traditional filling equipment, due to the lack of a flexible and precise adjustment mechanism, has difficulty in accurately adjusting the positioning of filling materials such as soil into the blasting borehole according to the specific position, angle and shape of different boreholes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mine blasting borehole filling machine for preventing material blockage, comprising a mobile vehicle body, a fixed plate fixedly connected to the front end of the mobile vehicle body, a cylinder fixedly connected inside the fixed plate, a U-shaped connecting rod fixedly connected to the output end of the cylinder, a support plate fixedly connected inside the fixed plate, connecting rods rotatably connected to both ends of the U-shaped connecting rod, and an adjustment component provided at one end of the connecting rod;

[0026] 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.

[0027] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a mine blasting hole filling machine for preventing clogging, comprising a mobile vehicle 1 capable of moving a fixed plate 2 and a clamp 10 connected thereto, enabling the equipment to flexibly reach different blasting hole positions, realizing soil transportation and blasting hole filling operations. A fixed plate 2 is fixedly connected to the front end of the mobile vehicle 1, and a cylinder 21 is fixedly connected inside the fixed plate 2. After the cylinder 21 is started, the piston movement at its output end drives the U-shaped connecting rod 6 to move. The U-shaped connecting rod 6 is fixedly connected to the output end of the cylinder 21, transmitting the linear motion output by the cylinder 21 to a connecting rod 22, allowing the connecting rod 22 to move along a predetermined trajectory, thereby driving the fixed rod. 8 moves to adjust the angle of clamp 10. A support plate 7 is fixedly connected inside the fixed plate 2. During the movement of the fixed rod 8, one end of the connecting rod 9 moves with the fixed rod 8, and the other end rotates at both ends of the support plate 7, so that the fixed rod 8 can rotate around the connection between the connecting rod 9 and the support plate 7, ensuring the accuracy and stability of the angle adjustment of clamp 10. Both ends of the U-shaped connecting rod 6 are rotatably connected to the connecting rod 22. When the U-shaped connecting rod 6 moves, the connecting rod 22 will swing, transmitting the movement of the U-shaped connecting rod 6 to the fixed rod 8, causing the fixed rod 8 to move and rotate, thereby driving the clamp 10 to adjust the angle. One end of the connecting rod 22 is provided with an adjustment component.

[0028] The adjustment assembly includes a fixed rod 8 and a connecting rod 9. The fixed rod 8 is rotatably connected to one end of the connecting rod 22. It moves and rotates under the drive of the connecting rod 22, directly driving the clamp 10 to move. On the other hand, it drives the connecting rod 9 and the rotating sleeve 12 to move. One end of the connecting rod 9 is rotatably connected to the outer wall of the fixed rod 8. When the fixed rod 8 moves, one end of the connecting rod 9 moves with the fixed rod 8, and the other end rotates on the support plate 7, providing support and guidance for the rotation of the fixed rod 8 and ensuring the smoothness of the angle adjustment of the clamp 10. The rotating sleeve 12 is fixedly connected to the outer wall of the fixed rod 8. When the fixed rod 8 moves, the rotating sleeve 12 moves accordingly, driving the telescopic rod 11 to stretch or contract between the fixed rod 8 and the fixed plate 2, providing auxiliary support for the rotation of the clamp 10. One end of the rotating sleeve 12 is fixedly connected to the telescopic rod 11, and the clamp 10 is fixedly connected to the outer wall of the fixed rod 8. Driven by the moving vehicle 1, the clamp 10 can scoop up the soil and push it into the blast hole for filling.

[0029] Specifically, the mobile vehicle 1 is started first, which moves the fixed plate 2 and the clamp 10. The operator maneuvers the vehicle to approach the blast hole, uses the clamp 10 to shovel soil and push it into the hole for initial filling. Then, the cylinder 21 is started, and its piston extends to move the U-shaped connecting rod 6 linearly. The U-shaped connecting rod 6 then moves the connecting rod 22, causing the fixed rod 8 to move. When the fixed rod 8 moves, the connecting rod 9 moves accordingly, allowing the fixed rod 8 to rotate around its connection point with the support plate 7. At the same time, the rotating sleeve 12 drives the telescopic rod 11 to stretch, assisting in adjusting the angle of the clamp 10 and precisely adjusting the position of the soil in the hole.

[0030] Reference Figure 4 - Figure 6A support column 3 is fixedly connected to the outer wall of the fixed plate 2, providing installation support for the electric push rod 4. The electric push rod 4 is fixedly connected inside the support column 3. After the electric push rod 4 is started, the push rod at its output end extends or retracts, driving the connecting seat 13 to move. This causes the pressure plate 5 at the bottom of the connecting seat 13 to slide inside the blast hole, pressing down the filled soil to prevent the soil from clogging the blast hole. The output end of the electric push rod 4 is fixedly connected to the connecting seat 13, which moves under the drive of the electric push rod 4, driving the positioning seat 14 and the pressure plate 5 below to slide together inside the blast hole, realizing the compaction operation of the soil. The bottom of the connecting seat 13 is slidably connected to the positioning seat 14, and the lower surface of the positioning seat 14 is fixedly connected to the pressure plate 5, which slides inside the blast hole under the drive of the electric push rod 4, pressing down the filled soil. By applying pressure, the soil is made more compact, preventing loosening and blockage within the blast hole, thus improving the quality of blast hole filling. The connecting seat 13 has an internal disassembly assembly, including a fixing block 17. When disassembling and installing the pressure plate 5, the fixing block 17 slides within the connecting seat 13 and the positioning seat 14. Working in conjunction with the threaded sleeve 18 and the spring 16, it enables quick disassembly and assembly of the positioning seat 14 and the pressure plate 5. The outer wall of the fixing block 17 is slidably connected to the inside of the connecting seat 13. The outer wall of the fixing block 17 has external threads 20 and is threadedly connected to the threaded sleeve 18. When disassembling the pressure plate 5, rotating the threaded sleeve 18 separates it from the fixing block 17, releasing the constraint on the positioning seat 14. When installing the pressure plate 5, rotating the threaded sleeve 18 reconnects it to the fixing block 17, fixing the positioning seat 14. A limit ring 19 is fixedly connected to the outer wall of the fixing block 17, limiting the sliding range of the fixing block 17 within the connecting seat 13 and preventing excessive sliding or detachment. A sliding rod 15 is slidably connected inside the connecting seat 13 and the fixing block 17. The sliding rod 15 provides guidance for the sliding of the fixing block 17, ensuring that the fixing block 17 can slide smoothly and accurately inside the connecting seat 13. A spring 16 is sleeved on the outer wall of the sliding rod 15. When disassembling the pressure plate 5, pressing the fixing block 17 causes the spring 16 to retract. When installing the pressure plate 5, the spring 16 rebounds, pushing the fixing block 17 to reset and re-fixing the positioning seat 14 onto the connecting seat 13, thus realizing the quick installation and fixation of the pressure plate 5. One end of the spring 16 is fixedly connected to the outer wall of the fixing block 17, and the other end of the spring 16 is fixedly connected to the inside of the connecting seat 13. The outer wall of the sliding rod 15 is fixedly connected to the inside of the connecting seat 13. The outer wall of the limiting ring 19 is slidably connected to the inside of the connecting seat 13. The external thread 20 matches the internal thread of the threaded sleeve 18. One end of the connecting rod 9 is rotatably connected to the outer wall of the fixing plate 2, and one end of the telescopic rod 11 is rotatably connected to the inside of the fixing plate 2. The clamps 10 are set on both sides of the pressure plate 5.

[0031] Specifically, start the electric push rod 4 to push the connecting seat 13 to move along the track. The connecting seat 13 drives the positioning seat 14 and the pressure plate 5 below to slide in the hole, compacting the soil to prevent blockage. If the pressure plate 5 needs to be replaced, rotate the threaded sleeve 18 to separate it from the fixing block 17 and remove it. Press the fixing block 17 to make it slide in the slide, compress the spring 16, release the constraint on the positioning seat 14, remove the old pressure plate 5, and when installing the new pressure plate 5, put the positioning seat 14 back in its original position. The spring 16 will rebound, the fixing block 17 will reset, and the installation will be completed.

[0032] Working principle: When a mine blasting borehole filling machine using anti-blocking material is needed, firstly, the moving vehicle 1 is started, moving the fixed plate 2 and clamp 10 to push the soil into the blasting borehole for filling. Additionally, the cylinder 21 is started, moving the U-shaped connecting rod 6. This, in turn, moves one end of each of the two connecting rods 22 via the two ends of the U-shaped connecting rod 6. The other end of the connecting rod 22 then moves the fixed rod 8. The movement of the fixed rod 8 then pushes it relative to the clamp 10. During this process, the movement of the fixed rod 8 causes one end of the connecting rod 9 to move further inwards. The movement of the connecting rod 9 causes the other end of the connecting rod 9 to rotate at both ends of the support plate 7, thereby causing the fixed rod 8 to rotate around the connection point between the connecting rod 9 and the support plate 7. The rotation of the fixed rod 8 then adjusts the clamp 10. At the same time, the movement of the fixed rod 8 drives the rotating sleeve 12 to move, thereby stretching the telescopic rod 11 between the fixed rod 8 and the fixed plate 2. This assists in the rotation of the clamp 10, making it more stable and allowing the angle of the clamp 10 to be adjusted. This allows the soil to be adjusted and positioned inside the blast hole.

[0033] In addition, after the soil is filled into the blast hole, the electric push rod 4 is activated to drive the pressure plate 5 to slide inside the blast hole in conjunction with the connecting seat 13, thereby pressing down the soil to prevent blockage. At the same time, the threaded sleeve 18 is driven to rotate on the outer wall of the fixing block 17. The threaded sleeve 18 can be removed by cooperating with the fixing block 17. After removal, the fixing block 17 is pressed to slide inside the positioning seat 14 and the connecting seat 13. At the same time, the spring 16 retracts. When the fixing block 17 has completely moved into the connecting seat 13, the positioning seat 14 and the pressure plate 5 can be removed and the pressure plate 5 adapted to the blast hole can be replaced. During installation, the positioning seat 14 only needs to be put back in its original position, and then the spring 16 can be used to fix the positioning seat 14 again, realizing disassembly and assembly.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
