Abstract
Description
Technical Field
[0001] This invention relates to the field of blast hole plugging device technology, specifically a novel blast hole plugging device. Background Technology
[0002] In blasting operations, plugging is crucial. Effective plugging slows the escape rate of explosive gases, prolongs their impact time on the rock mass, thereby improving rock fragmentation and significantly increasing the utilization rate of explosive energy. Simultaneously, plugging suppresses flyrock hazards and reduces noise and vibration intensity generated by blasting. However, current borehole plugging methods generally suffer from numerous problems. Commonly used plugging materials (such as rock powder) have poor sealing properties, making it difficult to adhere tightly to the borehole wall, leading to explosive gas leakage and affecting blasting effectiveness. Furthermore, some plugging materials cannot withstand the blast impact, easily resulting in perforation and energy loss. Therefore, there is an urgent need to develop new plugging devices to enhance blasting effects and improve blasting efficiency.
[0003] To improve the plugging effect of blast holes, many researchers have tried adding mixing agents to the plugging materials. However, existing mixing agents have obvious shortcomings: they either have poor water expansion properties, which cannot fully fill the tiny gaps in the blast hole; or they have poor density, which cannot effectively prevent the leakage of explosive gases to enhance the blasting effect.
[0004] Existing manual packing methods have revealed numerous problems in practical applications. Firstly, there is the arbitrariness in material preparation. On-site batching relies heavily on worker experience, and manual feeding makes it difficult to ensure the precise proportions of various dry powder materials such as rock powder and cement. This inaccuracy directly leads to batch-to-batch fluctuations in the performance of the final packing material, resulting in poor quality stability. Even more problematic is that dry powder easily forms "half-cooked" lumps upon mixing with water, which ordinary mixing equipment struggles to completely break up, making insufficient uniformity of the mixture a common issue.
[0005] During the packing process, manual tamping using tools such as tamping rods is extremely labor-intensive and results in uneven tamping force, easily leaving voids and air bubbles within the packing material. These voids not only weaken the overall strength of the packing material but also reduce its tightness against the borehole wall, posing a potential hazard to the blasting effect and safety. Summary of the Invention

[0017] This invention provides a novel device for plugging blasting boreholes. It has the following beneficial effects:
[0018] 1. This invention achieves the coordinated control of automated lifting and precise feeding of materials in a hopper and double baffles through the cooperation of the internal structures of the feeding components. At the same time, the motor moves the arc plate and protrusion along the suspension rope, controlling the feeding rate while initially dispersing the raw materials. This solves the problems of high labor intensity, low efficiency and inaccurate feeding caused by traditional manual feeding. It also avoids the series of technical problems caused by the stratification of multiple dry powders due to one-time mixing and feeding, and the instantaneous agglomeration of powders upon contact with moisture when entering the mixing chamber due to excessive concentration, forming a "half-cooked" core that is difficult to disperse, ultimately leading to poor mixing uniformity and unstable clogging performance.
[0019] 2. This invention achieves the effect of constant temperature preheating of the mixing chamber by the temperature controller and heating jacket, precise injection of the required amount of water by the solenoid valve, and crushing and mixing by the coordinated action of the stirring blades and the crushing roller. This solves the problems of the influence of ambient temperature changes on the hydration reaction rate and final coagulation performance of the blockage material, as well as the problem of the material easily agglomerating and forming "half-raw" material after encountering water, resulting in insufficient mixing and unstable blockage quality.
[0020] 3. This invention achieves the effect of synchronously vibrating and compacting the plugging material injected into the blast hole by coordinating the internal structures of the conveying components, with the flow of plugging material controlled by solenoid valve two and the high-frequency vibration of the filling plate driven by motor three. This solves the problem that the plugging material is prone to trapping gas and forming internal voids during the filling process due to its own viscosity, resulting in an incomplete plugging body and insufficient bonding strength with the hole wall, which in turn affects the overall plugging quality and the utilization rate of blasting energy.

[0031] The technical solutions in 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.
[0032] Please see the appendix Figure 1 - Appendix Figure 6This invention provides a novel blasting borehole plugging device, comprising: a base plate 1, with a plurality of hydraulic rods 4 fixed on the upper surface of the base plate 1, and a stirring assembly 6 disposed at the driving end of each hydraulic rod 4; the stirring assembly 6 includes a stirring chamber 601, the lower surface of which is fixed to the driving end of the hydraulic rods 4; and a feeding assembly 5 disposed on the stirring chamber 601, the feeding assembly 5 including a feeding pipe 501, the bottom end of which penetrates the stirring chamber 601, and the upper surface of the feeding pipe 501... A hopper 502 is fixed in place. A baffle 503 is slidably connected inside the hopper 502. A second baffle 504 is also slidably connected inside the hopper 502, positioned above the first baffle 503. A connecting pipe 505 passes through the outer side of the hopper 502, with its end positioned below the second baffle 504 for separating the feeding. A second hopper 506 is fixed to the top of the connecting pipe 505. A water injection component 7 is installed on the mixing chamber 601 for water injection. Water is added inside the mixing chamber 601; a conveying assembly 8, located at the bottom of the mixing chamber 601, is used to convey the mixed raw materials to the inside of the borehole. Two symmetrical hinge blocks 507 are fixed to the top inner surface of the mixing chamber 601. Connecting rods 508 are hinged inside the hinge blocks 507. Connecting plates 509 are fixed to the ends of the connecting rods 508. Arc-shaped plates 510 are fixed to the outer walls of the connecting plates 509. Multiple protrusions 511 are fixed to the outer walls of the arc-shaped plates 510. The upper surface of 601 is fixed with symmetrical fixing plates 512. The outer wall of the fixing plates 512 is fixed with motors 513. The drive end of the motors 513 is fixed with take-up rollers 514. The outer wall of the take-up rollers 514 is provided with hanging ropes 515. The end of the hanging ropes 515 is fixed with connecting rings 516. The lower surface of the connecting rings 516 is fixed to the connecting rods 508. The lower surface of the base plate 1 is connected with multiple casters 2 by bolts. The upper surface of the base plate 1 is fixed with a support plate 3.
[0033] Specifically, during operation, the machine is flexibly moved by the casters 2 and precisely lifted and leveled by multiple hydraulic rods 4. Power is supplied to the entire machine by the power source supported by the support plate 3. Its feeding assembly 5, with hopper one 502 and hopper two 506 separated by a connecting pipe 505, enables independent loading and separate storage of two types of dry powder materials. By sequentially pulling out baffle one 503 and baffle two 504, materials can be fed into the mixing chamber 601 via the feeding pipe 501 according to a preset sequence. More ingeniously, during the material's descent, the motor one 513 on the fixed plate one 512 drives the winding roller 514 and the lifting rope 515, which are connected via the connecting ring 5. Pulling the connecting rod 508 hinged to the hinge block 507 causes the arc plate 510 and multiple protrusions 511 on the connecting plate 509 to generate high-frequency reciprocating motion. This not only forcibly disperses the falling material flow to form a uniform material curtain, greatly improving the pre-dispersion effect of the material, but also fundamentally solves the deep-seated technical problems in traditional feeding methods, such as dry stratification caused by differences in powder density and particle size, and the stubborn "half-raw" core formed by the powder flow being too concentrated and instantly encountering water, which leads to subsequent mixing being less effective and uneven product quality. This ensures that the raw materials entering the mixing component 6 are in the best state for mixing.
[0034] Please see the appendix Figure 7 - Appendix Figure 8A housing 603 is fixed to the outer wall of the mixing chamber 601. An operation panel 602 is fixed to the outer wall of the mixing chamber 601. A second motor 604 is fixed inside the housing 603. A rotating rod 605 is fixed to the drive end of the second motor 604. The outer wall of the rotating rod 605 rotates inside the mixing chamber 601. Multiple stirring blades 606 are fixed to the outer wall of the rotating rod 605. A gear 607 is fixed to the outer wall of the rotating rod 605. A symmetrical rotating rod 608 rotates on the inner wall of the mixing chamber 601. A gear 609 is fixed to the outer wall of each rotating rod 608. The gears 609 and gears 607 mesh with each other. A crushing roller 610 is fixed to the outer wall of each rotating rod 608. The crushing roller 610 is located on both sides of the stirring blades 606. The water injection assembly 7 includes a water injection pipe 701. The bottom of the water injection pipe 701... A water tank 702 is fixed to the top of a water injection pipe 701, which passes through a mixing chamber 601. A solenoid valve 703 is installed inside the water injection pipe 701. A connecting water pipe 704 is fixed to the top of the mixing chamber 601. A heating jacket 706 is fixed to the outer wall of the water tank 702. A drain pipe 707 passes through the outer side of the heating jacket 706. An inlet pipe 708 passes through the outer side of the heating jacket 706. Switch valves 709 are installed inside both the inlet pipe 708 and the drain pipe 707. A heating plate 711 is fixed to the outer wall of the heating jacket 706. A temperature controller 712 is fixed to the outer wall of the heating jacket 706. The temperature controller 712 and the heating plate 711 are electrically connected. An observation window 705 is provided on the outer side of the water tank 702. A scale line 710 is fixed to the outer wall of the water tank 702 and is located on one side of the water tank 702.
[0035] Specifically, all operations are controlled via an integrated control panel 602. When the dry powder enters the mixing chamber 601, the temperature controller 712 of the water injection component 7 activates the heating plate 711 to provide heat to the heating jacket 706 outside the water tank 702. The circulating medium is controlled by the switching valves 709 in the inlet pipe 708 and outlet pipe 707, thus preheating the water in the water tank 702 to a constant temperature that activates the optimal chemical reaction activity of the blockage material. After the operator confirms the water volume through the observation window 705 and the scale line 710, the solenoid valve 703 precisely opens, injecting the constant-temperature water into the chamber via the water injection pipe 701 and the connecting water pipe 704, almost simultaneously... During this process, the motor 604 inside the casing 603 starts powerfully, driving multiple stirring blades 606 on the main rotating rod 605 to perform circumferential macro-stirring, forming a powerful material vortex. More importantly, the gear 607 on the main rotating rod 605 simultaneously meshes to drive the gear 609 on the two rotating rods 608 on both sides, causing the crushing roller 610 to perform high-frequency opposing extrusion and grinding. This solves the problem that a single stirring method cannot effectively break up stubborn clumps formed instantly upon contact with moisture. Combined with the precise temperature and quantity control functions of the water injection component 7, the influence of ambient temperature fluctuations on the hydration rate and coagulation performance of the blockage material is eliminated, ensuring a high degree of consistency in the quality of the blockage body.
[0036] Please see the appendix Figure 8 - Appendix Figure 9 The conveying assembly 8 includes a discharge pipe 801, the end of which is fixed to the bottom of the mixing chamber 601. A support block 803 is fixed to the bottom of the discharge pipe 801. A solenoid valve 802 is installed inside the discharge pipe 801. A packing plate 804 is bolted to the lower surface of the support block 803. Multiple fixing plates 805 are fixed to the upper surface of the support block 803. A motor 806 is fixed to the upper surface of each fixing plate 805. An eccentric wheel 807 is fixed to the drive end of each motor 806. A battery 9 is fixed to the outer wall of the support plate 3. The battery 9 is electrically connected to motor 513, motor 604, and motor 806 respectively to supply power to them.
[0037] Specifically, in the final conveying and packing operation, a unified storage battery 9 provides stable and independent power support for all motors, including motor one 513, motor two 604, and motor three 806. After the slurry is mixed, solenoid valve two 802 opens precisely, and the slurry flows to the packing plate 804 through the discharge pipe 801 under gravity. At the same time, multiple motors three 806 on the fixed plate two 805 drive the eccentric wheel 807 to rotate at high speed, generating strong and continuous high-frequency vibration. This vibration is efficiently transmitted to the support block 803. The 804 packing plate, with its simultaneous "discharge and vibration" operation, has far-reaching benefits beyond simple physical compaction. It can cause a momentary "liquefaction" effect in viscous slurry, greatly improving its fluidity and permeability. This allows it to fill even the smallest cracks and irregular depressions on the borehole wall, forming a strong mechanical interlocking force. More importantly, the high-frequency vibration can force out air bubbles trapped in the slurry during its fall and filling process, fundamentally eliminating the hidden dangers of internal voids that lead to a decrease in the strength of the blockage and the formation of energy leakage channels.
[0038] Working principle: For the clogging operation of blast holes with a diameter of 100mm and a depth of 15m, the equipment is first moved to the top of the blast hole by the multiple casters 2 under the base plate 1, ensuring that the discharge pipe 801 and the clogging device are aligned with the hole opening. Then, the fixing bolts are closed or the hydraulic rod 4 is activated to lift and level the mixing assembly 6 as a whole to prevent the device from slipping.
[0039] The entire device is powered by a battery 9 fixed on the support plate 3. The operator adds rock powder with a particle size of ≤3mm and mixing agent to the feed hopper 2 506 and feed hopper 1 502 respectively through the feed inlet, and strictly controls the mass ratio of rock powder to mixing agent to be 8:1. Then, the baffle 1 503 and baffle 2 504 are pulled open so that the two dry materials fall into the mixing chamber 601 in sequence through the feeding pipe 501. During this process, the motor 1 513 fixed on the fixed plate 1 512 drives the winding roller 514 to tighten the hanging rope 515. The connecting rod 508 is pulled through the connecting ring 516, which drives the arc plate 510 and the protrusion 511 to initially disperse the falling powder and control the rate.
[0040] At the same time, the operator fills the water tank 702 with water and ensures that the amount of water added is about 20% of the mass of rock powder by observing the window 705 and the scale line 710. The temperature controller 712 starts the heating plate 711 to heat the heating jacket 706 and adjusts the water temperature to a suitable temperature. Then, the solenoid valve 703 is opened through the operation panel 602 to inject the constant temperature water into the mixing chamber 601 through the water injection pipe 701.
[0041] Immediately, motor 604 inside the casing 603 starts, driving multiple stirring blades 606 on rotating rod 605 to perform macroscopic stirring. At the same time, gear 607 on rotating rod 605 meshes with gear 609 on rotating rod 608, causing the crushing rollers 610 on both sides to rotate in opposite directions, forcefully squeezing and crushing the material clumps until the material is fully mixed and reaches the ideal state of starting to expand 8 minutes after injection, reaching a stable volume in 25 minutes, and an expansion ratio of about 2.2 times. Then, the motor is stopped and solenoid valve 802 in the discharge pipe 801 is opened, allowing the mixture to be injected into the borehole. Multiple motors 806 fixed on the fixing plate 805 drive the eccentric wheel 807 to rotate at high speed, generating high-frequency vibration, which is transmitted to the filling plate 804 through the support block 803, synchronously vibrating and compacting the injected mixture to ensure complete blockage of the borehole, achieving integrated injection, compaction, and rapid drying. After filling is completed, solenoid valve 802 is closed and the power is cut off to complete the entire process.
[0042] The mixing agent consists of an expanding agent, a binder, a retarder, a water-retaining agent, and a filler, with a mass ratio of 40:30:4:2:15. Specifically, the expanding agent is a calcium sulfoaluminate-calcium oxide composite expanding agent (CSA type); the binder is a mixture of composite cement (42.5 grade ordinary Portland cement + 5% gypsum) and polyvinyl alcohol (PVA) powder; the retarder is citric acid; the water-retaining agent is hydroxypropyl methylcellulose ether (HPMC); and the filler is quartz sand.
