Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to an integrated machine for soil crushing and reconstruction in mine spoil heaps. Background Technology

[0002] The mining and processing of mineral resources generate large amounts of waste, which typically accumulate to form spoil heaps. Due to long-term compaction, weathering, and a lack of organic matter, the soil in these spoil heaps often exhibits characteristics of hardening and infertility. This harsh soil environment severely restricts vegetation restoration and ecosystem reconstruction. To promote the ecological restoration of mine spoil heaps, it is often necessary to break up and reconstruct the soil to improve its structure, and to apply remediation solutions to replenish nutrients, neutralize acids and alkalis, or degrade pollutants.

[0003] Existing soil remediation technologies applied to mine spoil heaps typically treat soil breaking and remediation solution application as two separate, sequential operations. For example, heavy machinery such as bulldozers or excavators is used to initially loosen compacted soil, followed by spraying with remediation solution by sprinkler trucks or other fertilization equipment. This phased approach has significant technical drawbacks. First, after breaking up the soil, it is exposed to air and quickly subjected to compaction or wind erosion, weakening its structural improvement effect and affecting the penetration efficiency of subsequent remediation solutions. Second, the two separate operations require coordination of different equipment and personnel, increasing operating costs and time, reducing overall remediation efficiency, and easily causing delays in equipment switching and on-site scheduling. This can prevent the remediation solution from being applied to the newly broken soil in a timely manner, missing the optimal time for penetration and absorption.

[0004] Therefore, this utility model proposes an integrated machine for soil crushing and reconstructing in mine spoil heaps to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an integrated machine for soil crushing and reconstructing in mine spoil heaps, which aims to improve the problems in existing soil remediation schemes for mine spoil heaps, such as low work efficiency, insufficient penetration of remediation liquid, and inconvenience in adding, filtering and stirring the remediation liquid in the tank.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an integrated machine for soil crushing and reconstructing in mine spoil heaps, comprising: a tracked chassis; a support platform; a reagent tank; a crushing blade; a water pump; a connecting pipe; and a spraying mechanism; The tracked chassis serves as the basic platform for the equipment, with a support platform fixedly connected to it.

The input end of the water pump is connected to the inside of the chemical tank via a connecting pipe, and the output end of the water pump is connected to a spraying mechanism, which is fixedly connected to the rear of the crushing blade. The integrated soil crushing and reconstruction machine for mine spoil heaps also includes a feed pipe for injecting remediation fluid. The feed pipe is fixedly connected to the top of the chemical tank, and a filter assembly is slidably installed inside the feed pipe. The filter assembly includes a filter ring, and a sliding block is fixedly connected to the outer wall of the filter ring. A groove is opened on the inner wall of the feed pipe to slide and engage with the sliding block, and a pull rod is fixedly connected to the top of the sliding block. The integrated soil crushing and reconstruction machine for mine spoil heaps also includes a stirring assembly for stirring the remediation fluid. The stirring assembly is located inside the chemical tank and includes a motor, a rotating rod, a rotating frame, stirring blades, and a scraper. The motor is fixedly connected to the top of the medicine tank. The output end of the motor is rotatably connected to a rotating rod that extends into the medicine tank. A rotating frame is fixedly connected to the outer wall of the rotating rod. Stirring blades are fixedly connected to both the outer wall of the rotating rod and the outer wall of the rotating frame. A scraper is fixedly connected to the outer wall of the rotating frame. The scraper is arranged close to the inner wall of the medicine tank.

[0007] Preferably, the connecting tube extends into the bottom of the medicine container.

[0018] 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.

[0019] Reference Figures 1-5This utility model provides an embodiment of a soil crushing and reconstruction integrated machine for mine spoil heaps, comprising a tracked chassis 1, which provides driving force and a support platform for the entire integrated machine. A support platform 3 is fixedly connected to the tracked chassis 1 and serves as a load-bearing component, supporting a chemical tank 4 and a water pump 6. The chemical tank 4 is fixedly connected to the top of the support platform 3 and is used to store remediation fluid. A crushing blade 2 is fixedly connected to the inside of the tracked chassis 1 and crushes the soil when the tracked chassis 1 moves forward. The water pump 6 is fixedly connected to the inside of the tracked chassis 1. The pump 6 is fixedly connected to the top of the support platform 3. The input end of the pump 6 is connected to the inside of the chemical tank 4 through the connecting pipe 5. The output end of the pump 6 is connected to the spraying mechanism 7. The spraying mechanism 7 is fixedly connected to the rear of the crushing blade 2 and is responsible for spraying the repair liquid onto the freshly crushed soil. Through the movement of the tracked chassis 1, the crushing blade 2 pre-treats the soil. Then the spraying mechanism 7 works closely together to achieve precise and efficient application of the repair liquid. This realizes the integrated operation of soil crushing and repair liquid spraying, which greatly improves the repair efficiency and effect. The integrated soil crushing and reconstruction machine for mine spoil heaps is also equipped with a feed pipe 801 at the top of the reagent tank 4. The feed pipe 801 is used for injecting the repair fluid. A filter assembly 8 is slidably installed inside the feed pipe 801. The core of the filter assembly 8 is the filter ring 802. The filter ring 802 can effectively block impurities entrained in the repair fluid, ensuring the purity of the repair fluid and preventing impurities from entering the water pump 6 or clogging the spraying mechanism 7. A sliding block 803 is fixedly connected to the outer wall of the filter ring 802. The sliding block 803 slides in cooperation with the groove 805 opened on the inner wall of the feed pipe 801. The groove 805 provides a clear sliding trajectory for the sliding block 803. A pull rod 804 is fixedly connected to the top of the sliding block 803. By pulling the pull rod 804, the sliding block 803 is driven to slide in the groove 805, which can easily pull the filter ring 802 out of the feed pipe 801 for cleaning, greatly facilitating maintenance operations and extending the service life of the equipment. In addition, the integrated soil crushing and reconstruction machine for mine spoil heaps is equipped with a stirring component 9 inside the reagent tank 4. The stirring component 9 is used to ensure the uniformity of the repair liquid. The core power source of the stirring component 9 is a motor 901 fixedly connected to the top of the reagent tank 4. The output end of the motor 901 is rotatably connected to a rotating rod 902, which extends vertically into the reagent tank 4. A rotating frame 903 is fixedly connected to the outer wall of the rotating rod 902. Stirring blades 904 are fixedly connected to the outer walls of both the rotating rod 902 and the rotating frame 903. When the stirring blades 904 rotate, they stir the repair liquid. The reconstituted liquid generates a strong stirring effect. In particular, a scraper 905 is fixedly connected to the outer wall of the rotating frame 903. The scraper 905 is arranged close to the inner wall of the medicine tank 4. During the stirring process, the scraper 905 can scrape the inner wall of the medicine tank 4, effectively preventing particles or sediments in the repair liquid from adhering to the tank wall, keeping the tank wall clean, and ensuring the thoroughness of the stirring effect. After the motor 901 is started, the rotating rod 902 drives the rotating frame 903, the stirring blade 904 and the scraper 905 to rotate together, realizing efficient and uniform stirring of the liquid inside the medicine tank 4. The crusher blade 2 is a set of blades, fixedly connected to the inside of the tracked chassis 1. The crusher blade 2 is designed to physically crush and loosen the compacted soil in the mine spoil heap. The spraying mechanism 7 is located behind the crusher blade 2 and is fixedly connected. The spraying mechanism 7 includes multiple nozzles, which are arranged at equal intervals along the width of the crusher blade 2 to ensure that the repair liquid can evenly cover the entire crushing area. The water pump 6 draws the repair liquid from the chemical tank 4 through the connecting pipe 5 and atomizes it through the multiple nozzles of the spraying mechanism 7. Since the spraying mechanism 7 follows the crusher blade 2, the repair liquid can be sprayed onto the newly turned soil with the best permeability as soon as possible, achieving a seamless connection between crushing and spraying operations. The connecting pipe 5 extends into the bottom of the chemical tank 4 to ensure that the repair liquid can be extracted to the maximum extent. The filter assembly 8 is removably installed inside the feed pipe 801 for filtering impurities during the addition of repair fluid. Two symmetrical grooves 805 are opened on the inner wall of the feed pipe 801. The filter assembly 8 includes a filter ring 802. Two sliding blocks 803 are fixedly connected to both sides of the outer wall of the filter ring 802. In the assembled state, the two sliding blocks 803 are slidably engaged in the two grooves 805, providing precise guidance and limiting for the reciprocating pulling motion of the filter ring 802, ensuring a smooth and stable pulling process. The aperture of the filter ring 802 is smaller than the minimum inner diameter of the nozzle of the spraying mechanism 7, eliminating the nozzle clogging problem caused by impurities from the source. A pull rod 804 is fixedly connected to the top of each sliding block 803. The operator can pull the pull rod 804 to pull out the entire filter assembly 8 along the length of the groove 805 for cleaning or replacement. A stirring assembly 9 is installed inside the reagent tank 4 for continuous stirring of the repair solution. A motor 901 is fixed to the top of the reagent tank 4. The output shaft of the motor 901 extends downward and is rotatably connected to a rotating rod 902. A cross-shaped rotating frame 903 is fixedly connected to the outer wall of the rotating rod 902. Stirring blades 904 are fixedly connected to the outer walls of the rotating rod 902 and the four arms of the rotating frame 903. The stirring blades 904 are spiral-shaped and can generate a combined axial and radial flow when rotating. The liquid is sheared and mixed in all directions, resulting in better stirring effect. The end of the arm of the rotating frame 903 is fixedly connected to a scraper 905. The scraper 905 is made of corrosion-resistant flexible material and is arranged close to the inner wall of the reagent tank 4. When the rotating frame 903 rotates, the scraper 905 can scrape the inner wall of the reagent tank 4 to prevent material from settling and adhering. The front end of the tracked chassis 1 is equipped with a bulldozer to clear larger obstacles during the equipment's movement, facilitating subsequent crushing operations. To ensure maximum extraction and use of the remediation solution, the connecting pipe 5 extends to the bottom of the reagent tank 4, effectively preventing residual remediation solution at the bottom of the tank and improving reagent utilization. To enhance the efficiency and effectiveness of soil breaking, the breaking blade 2 can be specifically designed as a set of blades. This set of blades can adopt different shapes or arrangements to adapt to different types and hardness of soil conditions, ensuring thorough breaking. To achieve uniform coverage of the remediation solution on the broken soil, the spraying mechanism 7 includes multiple nozzles. These nozzles are arranged at equal intervals along the width of the breaking blade 2. The nozzles can be fan-shaped or cone-shaped spray nozzles to ensure that the spraying range and uniformity meet the remediation requirements. To effectively prevent impurities from clogging the spraying mechanism 7, the aperture of the filter ring 802 is smaller than the minimum inner diameter of the nozzles in the spraying mechanism 7. This design ensures that the remediation solution particles passing through the filter ring 802 are sufficiently fine and do not clog. To prevent nozzle blockage, the stirring blade 904 can be designed in a spiral shape to enhance the stirring effect of the repair fluid. When rotating, the spiral stirring blade 904 can generate downward axial flow and outward radial flow, so that the liquid inside the agent tank 4 forms a circulating flow, making the stirring more thorough and uniform. In order to effectively scrape off the deposits on the inner wall of the agent tank 4 and ensure the durability of the scraping effect, the scraper 905 is made of a corrosion-resistant flexible material, such as polyurethane, rubber or special polymer materials. These materials can withstand the corrosion of the repair fluid and have a certain degree of elasticity, so they can fit tightly against the tank wall for effective scraping. In order to clear larger obstacles during the movement of the equipment, the front end of the tracked chassis 1 is equipped with a bulldozer. The bulldozer can be made of high-strength wear-resistant steel and can be designed with an adjustable angle and height structure to adapt to different obstacles and terrain conditions.

[0020] Working principle: During soil remediation operations, the remediation solution is first injected into the reagent tank 4 through the feed pipe 801. During this process, the remediation solution flows through the filter assembly 8 located inside the feed pipe 801. Impurities in the remediation solution are intercepted by the filter ring 802, ensuring the purity of the liquid injected into the reagent tank 4. If the filter ring 802 needs cleaning due to excessive impurities, the pull rod 804 can be pulled upwards. The pull rod 804 drives the sliding block 803 to slide upwards along the slide groove 805, thereby completely removing the filter ring 802 from the feed pipe 801 for cleaning. After the repair solution is injected, the motor 901 fixed to the top of the reagent tank 4 is started. The output end of the motor 901 drives the rotating rod 902 to rotate, and the rotating rod 902 in turn drives the fixedly connected rotating frame 903, stirring blade 904 and scraper 905 to rotate together. The stirring blade 904 thoroughly stirs the repair solution in the reagent tank 4, so that its components are mixed evenly; at the same time, the scraper 905 rotates synchronously against the inner wall of the reagent tank 4, scraping off the sediment attached to the tank wall and resuspending it in the liquid to participate in the mixing, thus ensuring the uniformity and stability of the repair solution. After the operation begins, the tracked chassis 1 drives the entire integrated machine forward on the spoil heap. During this movement, the bulldozer blades at the front can pre-clear larger stones or obstacles from the surface. Immediately afterwards, the breaker blades 2, fixed inside the tracked chassis 1, forcibly break up and loosen the hard, compacted soil. At the moment the soil is broken, the spraying mechanism 7, located behind the breaker blades 2, begins operation. The water pump 6 draws pre-mixed remediation fluid from the chemical tank 4 and delivers it to the spraying mechanism 7 via the connecting pipe 5. The fluid is then evenly sprayed onto the newly loosened soil by multiple nozzles of the spraying mechanism 7. Because the breaking and spraying actions are closely integrated, the remediation fluid can immediately penetrate into the soil, greatly improving remediation efficiency and chemical utilization.
