Description

[0002] At present, the environmental protection pressure in open-pit mines is relatively high, especially for the problem of dust generated in the blasting process. Now a solution is: in the vertical blasthole, after the explosives are loaded in the lower part, a part of the part that should be filled with rock and soil debris is separated to be filled with water cannon mud, with the intention of using the explosion shock wave to hit the water in the water bag into water mist to achieve dust suppression and dust capture, and reduce the generation of dust in the blasting process; water cannon mud bags are special products for blasting dust removal and preventing electric sparks in tunnel blasting. They are made by injecting water into a cylindrical polyethylene plastic bag and sealing the mouth. Its length is generally 250-300mm, and its diameter is slightly smaller than the diameter of the blasthole. Water cannon mud bags are relatively easy to carry, so they are widely used in open-pit mines.

[0003] However, there are still some shortcomings in the process of dust reduction by filling water bags in the prior art: 1. The traditional method uses a flexible polyethylene tubular water bag. After measuring the predetermined size, it is tied at the bottom, and then the bag is manually filled with water through a water truck on site, and then tied at the top to make a water bag and put it into the blasthole. The operation is extremely inconvenient. The method of tying knots up and down is too primitive, and the water truck is prone to spilling when filling, and the site is muddy.

[0004] 2. Due to the different diameters of blasting holes, when the diameter of the blasting hole is large, the diameter of the water cannon mud bag is insufficient, resulting in the water cannon mud being unable to be stably placed in the blasting hole, affecting the water in the water cannon mud to become water mist during the subsequent blasting, thereby affecting the dust reduction effect.

[0034] Reference Figure 4-Figure 8In order to further optimize the water filling structure, the water filling structure also includes a one-way bearing 29 sleeved on the outer wall of the water injection pipe 23, the inner ring of the one-way bearing 29 is fixedly connected to the outer wall of the water injection pipe 23, the outer ring of the one-way bearing 29 is fixed with a first gear 30, the first gear 30 is rotatably set on the top of the lifting plate 17, one side of the limit block 21 is rotatably connected with a connecting rod 32, the bottom end of the connecting rod 32 is rotatably connected to the rack 31, the cooperation between the limit block 21 and the connecting rod 32 is used to drive the first gear 30 to rotate, and when the one-way bearing 29 rotates counterclockwise, it is in an active state with the water injection pipe 23, and when the one-way bearing 29 rotates clockwise, it is in a locked state with the water injection pipe 23.

[0035] Specifically, the electric push rod 22 drives the U-shaped plate 18 to move downward, and the limit block 21 moves downward to drive the connecting rod 32 to rotate. The connecting rod 32 drives the first gear 30 to rotate 90° through the cooperation of the rack 31 and the first gear 30. The first gear 30 is in a locked state with the water injection pipe 23 through the one-way bearing 29. Due to the friction between the conical rubber ring 26 and the connecting head 3, the rotating water injection pipe 23 drives the connecting head 3 and the water cannon mud bag body 1 to rotate synchronously. At this time, one of the limit strips 14 is aligned with the first give way groove 33, which is convenient for the later U-shaped plate 18 to move up and reset. It only needs to place the connecting head 3 in the U-shaped plate 18 to automatically complete the tasks of watering, collecting and placing, and the operation is extremely convenient.

[0036] Reference Figure 4 , Figure 5 and Fig. 9In order to realize the recycling and reuse of water resources, the equipment also includes a collection structure, which is arranged in the base 19 and is used to recover the water collected on the carrier plate 34. The filling equipment includes a collection bin 35 arranged in the base 19 and is used to collect water on the carrier plate 34. A liquid inlet hole 36 is provided on the top of the base 19, and a stopper 37 is also fixed on the top of the base 19. A liquid discharge hole 40 is provided in the carrier plate 34 to match the liquid inlet hole 36, and a plurality of blocking blocks 52 are fixed in the liquid discharge hole 40. A sealing bearing block 41 is also slidably connected in the liquid discharge hole 40, and these blocking blocks 52 are used to limit the sealing bearing block 41. A liquid discharge port 51 is provided in the sealing bearing block 41, and one of the blocking blocks 52 is specifically used to block the liquid discharge port 51. A trapezoidal groove 42 is provided on one side of the sealing bearing block 41, and a plug rod 43 is slidably penetrated on one side of the carrier plate 34, and one end of the plug rod 43 extends into the trapezoidal groove 42 and slidably matches with the trapezoidal groove 42. The plug rod 43 cooperates with the stopper 37. When the carrier plate 34 rotates to a certain position, the stopper 37 will block the plug rod 43. When the carrier plate 34 continues to rotate, the stopper 37 can make the plug rod 43 extend into the trapezoidal groove 42. The outer wall of the plug rod 43 is also sleeved with a second spring 44, one end of which is fixedly connected to the outer wall of the carrier plate 34, and the other end is fixedly connected to the outer wall of the plug rod 43. In addition, the outer wall of the screw rod 16 is rotatably sleeved with a connecting arm, one end of which is fixedly connected to the carrier plate 34.

[0037] Specifically, when the carrier plate 34 rotates 90 degrees, the insertion rod 43 on one side of the carrier plate 34 will touch the block 37, and the insertion rod 43 will extend into the trapezoidal groove 42 under the action of the block 37, and drive the sealing bearing block 41 to move upward, thereby releasing the blocking of the drainage port 51 by the blocking block 52. At this time, the water in the carrier plate 34 flows into the collection bin 35 under the connection and cooperation of the drainage hole 40, the drainage port 51 and the inlet hole 36, so as to facilitate the later reuse.

[0038] Reference Figure 6 and Figure 7 Furthermore, an electromagnet 28 is fixed to the bottom end of the T-bar 27 , and the magnetic attraction between the electromagnet 28 and the magnetic disk 10 is greater than the magnetic attraction between the magnet block 11 and the magnetic disk 10 .

[0039] Specifically, when the electromagnet 28 is energized, it will generate a magnetic attraction force on the magnetic disk 10 that is greater than that of the magnet block 11 on the magnetic disk 10. At this time, the magnetic disk 10 will move up, and the magnet block 11 will fall into the water cannon mud bag body 1 after losing the magnetic attraction of the magnetic disk 10. At this time, after the water cannon mud bag branch bag 2 loses the traction of the connecting main rope 12 and the connecting branch rope 13, it extends to both sides under the pressure of water, and then the water cannon mud bag branch bag 2 can be extended into the blasting hole, and the water cannon mud bag body 1 can be stably placed in the blasting hole. This helps to increase the coverage of the water mist and improve the dust reduction effect.

[0040] Reference Figure 6 and Figure 7 A first clearance groove 33 is provided on the inner wall of one side of the U-shaped plate 18 , and the first clearance groove 33 is used to make way for the limiting strip 14 .

[0041] Specifically, when the U-shaped plate 18 moves downward, the water injection pipe 23 and the connector 3 will rotate 90° clockwise, at which time one of the limit strips 14 will be aligned with the first clearance groove 33, so as to facilitate the subsequent upward movement and restoration of the U-shaped plate 18.

[0042] Example 2

[0043] refer to Fig.10 , improved on the basis of Example 1: Finally, a rotating rod 45 is fixed longitudinally in the vertical frame 15, and a second gear 46 is fixed to the outer wall of the rotating rod 45 and the top of the connecting arm, and the second gear 46 located at the top of the connecting arm is rotatably sleeved on the outer wall of the screw rod 16. The two second gears 46 are meshed with each other, and the outer wall of the rotating rod 45 is also provided with a track groove 48 and a vertical groove 49, and the bottom end of the track groove 48 is connected to the top end of the vertical groove 49. A pin block 47 is fixed at one end of the lifting plate 17, and the pin block 47 is slidably matched with the track groove 48 and the vertical groove 49 to drive the rotating rod 45 to rotate 90°. A second clearance groove 38 is also provided on one side of the vertical frame 15, which is used to make way for the carrying plate 34 and the connecting arm.

[0044] Specifically, when the screw rod 16 drives the lifting plate 17 and the pin block 47 to move downward, the cooperation between the pin block 47 and the track groove 48 will drive the rotating rod 45 to rotate 90 degrees and move downward along the vertical groove 49. The rotating rod 45 drives the carrier plate 34 to rotate 90 degrees through the meshing of the two second gears 46. At this time, the plug rod 43 on one side of the carrier plate 34 will touch the block 37. The plug rod 43 extends into the trapezoidal groove 42 and drives the sealing load-bearing block 41 to move upward, releasing the blocking of the blocking block 52 on the drain port 51. The water in the carrier plate 34 flows into the collection bin 35 under the connection and cooperation of the drain hole 40, the drain port 51 and the inlet hole 36, which is convenient for later reuse.

[0045] The method of using the filling equipment includes the following steps: S1. Select a water cannon mud bag body 1 of corresponding length according to the depth of the mine blasting hole, move the base 19 to the blasting hole through the U-shaped handrail 50 and the universal wheel under the base 19, align the circular hole 39 with the blasting hole, manually place the connector 3 on the top of the water cannon mud bag body 1 in the U-shaped plate 18, and the limit strips 14 on both sides of the connector 3 are placed on the U-shaped plate 18 to place and clamp the connector 3 and the water cannon mud bag body 1; S2, when filling water into the water cannon mud bag body 1, the output shaft of the electric push rod 22 drives the U-shaped plate 18 and the limit block 21 to move upward, the U-shaped plate 18 drives the connector 3 to move upward, the conical rubber ring 26 and the water injection pipe 23 are inserted into the connector 3, and the water injection pipe 23 pushes the closing plate 6 downward through the T-bar 27 and squeezes the first spring 7. At this time, the sealing of the closing plate 6 and the fixing ring 4 is released. Because the magnetic attraction between the magnet block 11 and the magnetic disk 10 previously pulls the connecting main rope 12 and the connecting branch rope 13 upward, the water cannon mud bag branch bag 2 extends into the water cannon mud bag body 1; then the external water pump pours water into the water cannon mud bag body 1 through the cooperation of the hose 24 and the water injection pipe 23, and the hose 24 is provided with a flow control valve for controlling the amount of water in the water cannon mud bag body 1; S3. When water is poured into the water cannon mud bag body 1, when overflow occurs, water will drip onto the carrying plate 34 along the water cannon mud bag body 1 to complete the water collection and prevent the site from becoming muddy. When the water cannon mud bag body 1 is filled with water, the motor drives the screw rod 16 to rotate, and the screw rod 16 drives the lifting plate 17 and the pin block 47 to move downward. The cooperation between the pin block 47 and the track groove 48 drives the rotating rod 45 to rotate 90° and move downward along the vertical groove 49. The rotating rod 45 drives the carrying plate 34 to rotate 90 degrees through the engagement of the two second gears 46. At this time, the insertion rod 43 on one side of the carrying plate 34 touches the block 37, and the insertion rod 43 extends into the trapezoidal groove 42 and drives the sealing load-bearing block 41 to move upward, releasing the blocking of the drainage port 51 by the blocking block 52. The water in the carrying plate 34 flows into the collection bin 35 through the liquid inlet hole 36, which is convenient for later reuse. S4, when the lifting plate 17 and the U-shaped plate 18 put the water cannon mud bag body 1 into the blasting hole, the electromagnet 28 is energized, and the magnetic attraction of the electromagnet 28 on the magnetic disk 10 is greater than the magnetic attraction of the magnet block 11 on the magnetic disk 10. At this time, the magnetic disk 10 moves up, and the magnet block 11 loses the magnetic attraction of the magnetic disk 10 and falls into the water cannon mud bag body 1. At this time, the water cannon mud bag branch bag 2 loses the traction of the connecting main rope 12 and the connecting branch rope 13, and extends to both sides under the pressure of water, so that the water cannon mud bag branch bag 2 can be extended into the blasting hole, and the water cannon mud bag body 1 is stably placed in the blasting hole, which helps to increase the coverage of the water mist and improve the dust reduction effect; S5. At the same time, the electric push rod 22 drives the U-shaped plate 18 to move downward, and the limit block 21 moves downward to drive the connecting rod 32 to rotate. The connecting rod 32 drives the first gear 30 to rotate 90° through the cooperation of the rack 31 and the first gear 30. The first gear 30 is in a locked state with the water injection pipe 23 through the one-way bearing 29. Due to the friction between the conical rubber ring 26 and the connecting head 3, the rotating water injection pipe 23 drives the connecting head 3 and the water cannon mud bag body 1 to rotate synchronously. At this time, one of the limit strips 14 is aligned with the first give way groove 33, which is convenient for the U-shaped plate 18 to move up and reset later. It only needs to place the connecting head 3 in the U-shaped plate 18 to automatically complete the tasks of watering, collecting and placing, and the operation is extremely convenient.

[0046] However, as is well known to those skilled in the art, the working principles and wiring methods of the electromagnet 28 and the electric push rod 22 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selections according to their needs or convenience.
