[0002] Currently, the commonly known method of filling boreholes in mines mainly relies on manually inserting stemming material into the borehole and then using a blasting rod to fill the borehole with the stemming material. Because manual filling of boreholes requires multiple uses of the blasting rod, it can easily damage the detonating equipment already installed in the borehole, increasing the risk of misfires. Furthermore, in large-section blasting operations, the difficulty and labor intensity of workers filling stemming material, especially in higher areas and using blasting rods, increases exponentially, negatively impacting efficient blasting operations.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1:

[0033] Reference Figures 1 to 10 As shown, this embodiment provides a mechanized and automated filling device for blasting boreholes, including a vehicle body 1. A storage tank 2 is fixedly connected to the middle of the top of the vehicle body 1. A slurry stirring mechanism is rotatably installed inside the storage tank 2. A feeding pipe 10 is fixedly connected to the top wall of the storage tank 2. A support part is fixedly connected to one end of the top of the vehicle body 1. A slurry pumping part is fixedly connected to the bottom of the support part. The inlet end of the slurry pumping part is fixedly connected to the bottom of the side wall of the storage tank 2. The outlet end of the slurry pumping part is fixedly connected to one end of a grouting pipe 15. The grouting pipe 15 is vertically arranged. An angle adjustment part is fixedly connected to the bottom of the outer side wall of the grouting pipe 15. The bottom end of the angle adjustment part is fixedly connected to the top of the support part. A blasting barrel protection mechanism is fixedly connected inside the other end of the grouting pipe 15. An explosive box 7 is installed at the top of the vehicle body 1. A slurry pump is installed inside the explosive box 7. The feeding pipe 10 is connected to the slurry pump. Four wheels 8 are respectively installed at the four corners of the bottom of the vehicle body 1.

[0034] The slurry mixing mechanism installed in the storage tank 2 can mix the pre-stored filling slurry to ensure its fluidity and facilitate filling the slurry into the blasting borehole. The slurry pumping unit can pump the flowing slurry into the grouting pipe 15, and then fill it into the borehole through the grouting pipe 15. The angle adjustment unit can adjust the tilt angle of the grouting pipe 15 to ensure that the device can fill slurry into boreholes with any tilt angle. The blasting barrel protection mechanism can protect the blasting barrel that has been installed in the borehole during slurry filling to prevent the slurry from affecting the blasting process of the blasting barrel. The traveling wheels 8 can facilitate the movement of the device and improve the convenience of the blasting borehole filling operation.

[0035] The scheme is further optimized. The slurry mixing mechanism includes a motor 9, which is fixedly connected to the top wall of the storage tank 2. The output shaft of the motor 9 is fixedly connected to the top of a vertically arranged rotating shaft 25. The rotating shaft 25 is coaxially rotatably arranged inside the storage tank 2. A first mixing part is fixedly connected to the top of the outer wall of the rotating shaft 25, and a second mixing part is fixedly connected to the bottom of the outer wall of the rotating shaft 25. A wall scraping part is fixedly connected between the first mixing part and the second mixing part.

[0036] The scheme is further optimized. The first stirring part includes a straight rod 26. The center of the straight rod 26 is fixedly connected to the top of the outer wall of the rotating shaft 25. The bottom of one end of the straight rod 26 is fixedly connected to the top of a vertically arranged first connecting rod 31. The bottom of the other end of the straight rod 26 is fixedly connected to the top of a vertically arranged second connecting rod 32. The bottom of the first connecting rod 31 and the bottom of the second connecting rod 32 are both fixedly connected to stirring balls 33. The length of the first connecting rod 31 is different from the length of the second connecting rod 32.

[0037] The scheme is further optimized. The second stirring part includes a cross rod 28. The center of the cross rod 28 is fixedly connected to the bottom of the outer wall of the rotating shaft 25. A stirring plate 34 is fixedly connected to the top of each end of the cross rod 28. The stirring plate 34 is inclined and has several evenly arranged through holes 35.

[0038] The scheme is further optimized. The scraping part includes a top ring 27 and a bottom ring 29. The inner wall of the top ring 27 is fixedly connected to the end of the straight rod 26. The outer wall of the top ring 27 is in rotatable contact with the inner wall of the storage tank 2. The inner wall of the bottom ring 29 is fixedly connected to the end of the cross rod 28. The outer wall of the bottom ring 29 is in rotatable contact with the inner wall of the storage tank 2. Several scraping curved rods 30 are fixedly connected between the top ring 27 and the bottom ring 29. The several scraping curved rods 30 are equally spaced along the circumference of the inner wall of the storage tank 2. The scraping curved rods 30 are in rotatable contact with the inner wall of the storage tank 2.

[0039] The filling slurry is pre-added into the storage tank 2 through the feeding pipe 10. Then, the motor 9 is turned on, and the motor 9 drives the rotating shaft 25 to rotate. The rotating shaft 25 drives the straight rod 26 and the stirring ball 33 to rotate and stir the slurry. The two stirring balls 33 are located at different heights, which can improve the stirring effect of the slurry during rotation. The rotating shaft 25 also drives the cross rod 28 and the stirring plate 34 to rotate and stir the slurry. The tilt direction of the stirring plate 34 is opposite to the rotation direction of the rotating shaft 25, which can improve the stirring effect of the stirring plate 34 on the slurry. At the same time, the several through holes 35 opened on the stirring plate 34 can create a turbulence effect when stirring the slurry, further improving the stirring effect of the slurry. The top ring 27 and the bottom ring 29 rotate together with the straight rod 26 and the cross rod 28, which drives the wall scraper 30 to rotate synchronously. When the wall scraper 30 rotates, it continuously scrapes off the slurry adhering to the inner wall of the storage tank 2, which has the effect of cleaning the inner wall of the storage tank 2 and stirring the slurry.

[0040] The design is further optimized. The barrel protection mechanism includes an inner tube 21, which is coaxially installed inside the grouting pipe 15. Several fixing rods 23 are fixedly connected to one end of the outer wall of the inner tube 21. The fixing rods 23 are evenly spaced along the circumference and axial direction of the outer wall of the inner tube 21. The other end of the fixing rods 23 is fixedly connected to the inner wall of the grouting pipe 15. A slip ring 22 is slidably sleeved on the top of the outer wall of the grouting pipe 15. A rubber ring 24 is fixedly connected to the inner wall of the inner tube 21 near the slip ring 22. A sealing head 36 is fixedly connected to the other end of the inner tube 21. A straightening part is fixedly connected to the inner wall of the inner tube 21.

[0041] Furthermore, the top of the slip ring 22 is fixedly connected to the bottom of several vertically arranged square rods 39, the square rods 39 are evenly spaced along the circumference of the slip ring 22, and the top of the square rods 39 are detachably connected to a stop ring 40.

[0042] The stop ring 40 has several receiving grooves 41 inside, which are equally spaced along the circumference of the stop ring 40. A square groove 45 is connected in the middle of the receiving groove 41, and the square groove 45 is perpendicular to the receiving groove 41. A square rod 39 is slidably disposed in the square groove 45. One end of a spring 42 is fixedly connected to the inner wall of the receiving groove 41, and the other end of the spring 42 is fixedly connected to one end of a push rod 43. The push rod 43 is slidably disposed in the receiving groove 41, and the other end of the push rod 43 abuts against the side wall of the square rod 39. A pointed rod 44 is also slidably disposed inside the receiving groove 41 near the outer wall of the stop ring 40. A connecting ring 46 is fixedly connected in the middle of the side wall of the stop ring 40 near the slip ring 22. The end of the connecting ring 46 has several notches 47 that are adapted to the fixed rod 23.

[0043] The stop ring 40, as a sacrificial mechanism, is installed at the top of the grouting pipe 15. During installation, the square rod 39 is inserted into the square groove 45, and the spring 42 is compressed by the top rod 43. Simultaneously, the fixing rod 23 is engaged in the notch 47. Then, the end of the grouting pipe 15 is inserted into the borehole to be sealed. The outer wall of the grouting pipe 15 has dimensional graduation lines, which can be used to determine the sealing length inside the borehole. For example, if a 30cm length of sealing is required, the grouting pipe 15 is inserted into the borehole until the 30cm mark on the outer wall of the grouting pipe 15 is aligned with the borehole opening. Then, insertion is stopped. Then grouting begins. During the grouting process, as the grout gradually fills the space between the outer wall of the grouting pipe 15 and the inner wall of the blast hole, the grout begins to press down on the slip ring 22 under its own weight. The slip ring 22 moves towards the blast hole opening. During the movement, it drives the square rod 39 away from the square groove 45. At this time, the spring 42 returns to its original length from compression and pushes the top rod 43 outward. The top rod 43 then pushes the tip of the pointed rod 44 into the inner wall of the blast hole. In this way, the stop ring 40 can be fixed in the blast hole. After the stop ring 40 is fixed in the blast hole, it can prevent the grout from entering the gap between the two blasting columns in the blast hole and causing an impact on the blasting effect.

[0044] The scheme is further optimized. The straightening part includes several straightening plates 37. The several straightening plates 37 are equally spaced along the inner wall of the inner tube 21 in the circumferential and axial directions. The straightening plate 37 includes an arc-shaped segment 3701. Horizontal segments 3702 are fixedly connected to both ends of the arc-shaped segment 3701. The connection end between the arc-shaped segment 3701 and the horizontal segment 3702 is smoothly transitioned. The protruding side of the arc-shaped segment 3701 faces the center of the inner tube 21. The straightening plate 37 is fixedly connected to the inner wall of the inner tube 21 through the horizontal segment 3702.

[0045] The distance from the convex side of the arc-shaped segment 3701 to the center of the inner tube 21 is less than the distance from the inner wall of the rubber ring 24 to the center of the inner tube 21. The inner wall of the rubber ring 24 fits tightly against the outer wall of the barrel. In this way, after the barrel enters the inner tube 21, the rubber ring 24 can form a sealing effect on the outer wall of the barrel, preventing the filling grout from entering between the outer wall of the barrel and the inner wall of the inner tube 21. After the barrel enters the inner tube 21, the convex side of the arc-shaped segment 3701 of the centralizing plate 37 abuts against the outer wall of the barrel, ensuring that the barrel is located in the center of the inner tube 21. After the grouting pipe 15 enters the borehole, the slip ring 22 is located at the bottom of the borehole. As the grout continuously fills the borehole through the gap between the grouting pipe 15 and the inner tube 21, the grout continuously pushes the slip ring 22 toward the outlet position of the borehole until the slip ring 22 appears at the outlet position of the borehole, indicating that the grout in the borehole has been filled.

[0046] The scheme is further optimized. The support part includes four support legs 5, which are vertical and spaced apart. The bottom of the support legs 5 is fixedly connected to the top of the vehicle body 1. The top of the four support legs 5 is fixedly connected to a fixed platform 3. The bottom of the angle adjustment part is fixedly connected to the top of the fixed platform 3. The bottom of the four support legs 5 is fixedly connected to a pallet 4. The slurry pumping part is fixedly connected to the top of the pallet 4.

[0047] Further optimization of the scheme: the angle adjustment part includes a fixed plate 13. The center of the fixed plate 13 is fixedly connected to the bottom end of the outer wall of the grouting pipe 15. The two ends of the two opposite side walls of the fixed plate 13 are respectively fixedly connected to the lugs 20. The lugs 20 are rotatably connected to one end of the telescopic rod 14. The other end of the telescopic rod 14 is rotatably connected to the hinge shaft 19. The hinge shaft 19 is fixedly connected to the hinge seat 18. The bottom end of the hinge seat 18 is fixedly connected to the top end of the fixed platform 3.

[0048] During the actual grouting process, the blast hole has any tilt angle. At this time, the telescopic rod 14 is adjusted according to the tilt angle of the blast hole to adjust the grouting pipe 15 to the same tilt angle as the blast hole, so as to ensure that the grouting pipe 15 can be smoothly inserted into the tilted blast hole.

[0049] The scheme is further optimized. The slurry pumping unit includes a slurry pump 12, which is fixedly connected to the top of the pallet 4. The inlet end of the slurry pump 12 is fixedly connected to one end of the outlet pipe 11, and the other end of the outlet pipe 11 is fixedly connected to the bottom end of the side wall of the storage tank 2. The outlet end of the slurry pump 12 is fixedly connected to one end of the connecting hose 16, and the other end of the connecting hose 16 is fixedly connected to the small diameter end of the reducing pipe 17. The large diameter end of the reducing pipe 17 is fixedly connected to the bottom end of the grouting pipe 15.

[0050] The slurry pump 12 pumps the slurry inside the storage tank 2 into the grouting pipe 15, which then fills the blast hole.

[0051] Furthermore, a front end 6 is provided at the top of the vehicle body 1, and the movement of the entire device is controlled by the front end 6.

[0052] After the explosives are loaded into the explosives box 7, the borehole can be directly plugged and sealed. In addition, an intelligent controller can be installed on the explosives mixing vehicle, and the operation program for explosives loading and sealing can be pre-entered into the intelligent controller to realize intelligent control of explosives loading and sealing through the operation program.

[0053] This embodiment can also automate the control of the entire device by pre-editing the control program in the controller, thereby enabling the device to have the functions of automatic hole finding, automatic judgment of the length and density of the blockage in the hole;

[0054] Automatic hole finding function:

[0055] A high-definition camera is installed at the end of vehicle body 1. The movement of vehicle body 1 is controlled by a controller until the high-definition camera captures the blast hole. Then, the controller controls vehicle body 1 to make a fine adjustment of its position so that the grouting pipe 15 is aligned with the blast hole, thus completing the automatic hole finding.

[0056] The function of automatically determining the length and density of the blockage inside the hole:

[0057] An infrared distance detector is installed at the end of the grouting pipe 15. When the high-definition camera captures the blast hole and the grouting pipe 15 is aligned with the blast hole, the controller controls the infrared distance detector to work. The detector detects the depth of the blast hole and feeds the data back to the controller. The controller calculates the blockage length based on the received depth data and then controls the device to perform grouting and sealing work. After grouting is completed, the controller calculates the density of the grouting and sealing based on the grouting speed and grouting volume, combined with the pre-input blast hole volume.

[0058] Example 2:

[0059] Reference Figure 11 The difference between this embodiment and the first embodiment is that the large diameter end of the reducing pipe 17 is detachably connected to one end of the bend 38, and the other end of the bend 38 is detachably connected to the end of the grouting pipe 15. In this embodiment, the bend 38 allows the device to fill the upward blast hole with grout, thereby improving the versatility of the device.

[0060] In addition to filling upward blast holes in tunnels with slurry, this embodiment can also fill blast holes on the surface of open-pit mines with slurry.
