However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0023] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0024] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0025] like Figures 1 to 5 As shown, a first aspect of the present application provides a sludge scraping device, comprising: a scraping brush 50, a first linear movement mechanism 20, a second linear movement mechanism 30, and an elastic connection structure 40. The first linear movement mechanism 20 is used to drive the scraping brush 50 to move along a first direction. The second linear movement mechanism 30 is connected between the first linear movement mechanism 20 and the scraping brush 50 and is used to drive the scraping brush 50 to move along a second direction. The elastic connection structure 40 is connected between the second linear movement mechanism 30 and the scraping brush 50 and is used to provide a thrust to the scraping brush 50 toward the surface to be cleaned.

[0026] like Figure 2As shown, in this technical solution, the surface to be cleaned is generally the inner bottom surface of the vehicle body 11. The scraper part 50 can be a scraper blade or a scraper plate. In this embodiment, the scraper part 50 is a scraper blade. The first linear movement mechanism 20 and the second linear movement mechanism 30 respectively drive the scraper part 50 to move, thereby achieving the cleaning of sludge. The first direction of the first linear movement mechanism 20 and the direction of the second linear movement mechanism 30 are different. The first direction can be set to enable movement along the surface to be cleaned to scrape off the sludge, and the second direction can be set to enable the scraper part 50 to move towards the surface to be cleaned. The scraper 50 is moved by the second linear moving mechanism 30, moving away from or away from the surface to be cleaned. The position of the scraper 50 can be adjusted according to the amount of sludge inside, so that the scraper 50 moves closer to the surface to be cleaned until it is in contact with the surface. The first linear moving mechanism 20 drives the second moving mechanism and the scraper 50 to move, thus cleaning the sludge on the surface to be cleaned and improving the cleaning efficiency. The elastic connecting structure 40 makes the scraper 50 press tightly against the surface to be cleaned, thereby making the scraper 50 fit better with the inside of the vehicle body 11 and improving the cleaning effect.

[0027] Understandably, through the coordinated action of the first linear movement mechanism 20 and the second linear movement mechanism 30, precise control of the scraper 50 in a two-dimensional plane is achieved, solving the problems of cleaning dead zones, poor adaptability, and low efficiency in traditional cleaning methods. Specifically, the second linear movement mechanism 30 first performs a coarse adjustment action, moving the scraper 50 as a whole to a working range with a suitable distance from the surface to be cleaned, based on the thickness of the sludge accumulation or changes in the internal structure of the vehicle body 11. This step allows the device to cope with different working conditions. For example, when the sludge layer is thick, the scraper 50 can be lifted first to avoid excessive resistance or jamming during startup; when the sludge layer is thin, it can be adjusted to a position closer to the surface to be cleaned. On this basis, the elastic connection structure 40 provides crucial fine-tuning and adaptive functions. Because the inner bottom surface of the vehicle body 11 may become uneven due to corrosion, wear, or deformation after long-term use, the rigidly connected scraper 50 cannot fully fit, resulting in sludge residue in some areas. The elastic connection structure 40 continuously applies an elastic thrust towards the surface to be cleaned to the scraper 50. When the scraper 50 moves to a recessed area, the elastic element 43 extends, pushing the scraper 50 downwards to conform to that area; when it moves to a raised area, the elastic element 43 is compressed, allowing the scraper 50 to float upwards, thus avoiding equipment damage caused by hard impacts. This "floating" design ensures that the scraper 50 maintains close and effective contact with the surface to be cleaned throughout the entire cleaning stroke, significantly improving the cleanliness of a single cleaning, reducing the number of repetitive operations, and thus greatly improving overall cleaning efficiency and work quality.

[0028] like Figure 3 and Figure 4 As shown, in one feasible embodiment, the first linear motion mechanism 20 includes: a rotation drive mechanism 21, a transmission rod 23, a guide rod 22, a first slider 24, a second slider 25, and a first support member 26. One end of the transmission rod 23 is connected to the power output end of the rotation drive mechanism 21. The guide rod 22 is arranged on one side of the transmission rod 23. The first slider 24 is threadedly connected to the transmission rod 23. The second slider 25 is slidably connected to the guide rod 22. The first support member 26 is connected between the first slider 24 and the second slider 25.

[0029] In this technical solution, the transmission rod 23 can be either a screw or a lead screw. In this embodiment, the transmission rod 23 is a screw. When cleaning is required, the rotation drive mechanism 21 drives the transmission rod 23 to rotate, and the transmission rod 23 drives the first slider 24, which is threadedly connected to it, to rotate. Since the first slider 24 and the second slider 25 are connected through the first support member 26, and the second slider 25 is slidably connected to the guide rod 22, under the limiting action of the second slider 25, the rotation of the transmission rod 23 can drive the first slider 24 to move along the axial direction of the transmission rod. The first support member 26 moves with the first slider 24. The second linear movement mechanism 30 is set on the first support member 26. Therefore, the second linear movement mechanism 30 and the scraper part 50 move simultaneously with the first support member 26, thereby realizing the cleaning of sludge.

[0030] Understandably, the first linear motion mechanism 20 employs a transmission scheme combining a lead screw and nut (i.e., transmission rod 23 and first slider 24) and a linear guide rail (i.e., guide rod 22 and second slider 25), which has significant advantages such as structural stability, high transmission accuracy, strong load-bearing capacity, and good self-locking performance. The rotational drive mechanism 21 provides rotational power, and the transmission rod 23 precisely converts the rotational motion into the linear motion of the first slider 24. The guide pair formed by the guide rod 22 and the second slider 25 plays a crucial role in preventing rotation and providing support. It ensures that the first support member 26 will not deflect or wobble during movement due to thread clearance or uneven force between the first slider 24 and the transmission rod 23, thus guaranteeing the straightness of the movement trajectory. The first support member 26 acts as a connecting bridge, rigidly connecting the first slider 24 and the second slider 25 into a rigid moving unit, thereby stably transmitting the driving force from the transmission rod 23 to the second linear motion mechanism 30 mounted on it. This design ensures that the scraper 50 moves smoothly and accurately along the first direction, effectively overcoming the significant resistance encountered during the scraping process. It prevents poor cleaning results or equipment damage caused by mechanism vibration or displacement deviation. The first direction is generally the length of the vehicle body 11. Furthermore, the self-locking characteristic of the lead screw drive means that when the drive source 2101 is powered off or stops working, the first slider 24 can be stably locked in its current position, preventing the scraper 50 from undergoing unexpected displacement due to gravity or external forces, thus improving the safety and reliability of the equipment.

[0031] like Figure 3 As shown, in one feasible embodiment, the rotation drive mechanism 21 includes a drive source 2101, a first drive shaft 2102, a second drive shaft 2103, and a transmission member 2104. One end of the first drive shaft 2102 is connected to the output end of the drive source 2101, the second drive shaft 2103 is coaxially connected to one end of the transmission rod 23, and the transmission member 2104 is connected to the first drive shaft 2102 and the second drive shaft 2103 respectively.

[0032] In this technical solution, the drive source 2101 can be an electric motor, an internal combustion engine, or a motor. In this embodiment, the drive source 2101 is a servo motor. The power output end of the drive source 2101 is connected to the first transmission shaft 2102 through a shaft connector. The transmission component 2104 can be a gear drive or a belt drive. In this embodiment, the transmission component 2104 is a transmission belt. The transmission belt is mounted on the first transmission shaft 2102 and the second transmission shaft 2103. The rotation of the first transmission shaft 2102 drives the rotation of the second transmission shaft 2103 through the action of the transmission belt. The second transmission shaft 2103 is connected to the transmission rod 23 through a shaft connector, thereby driving the transmission rod 23 to rotate.

[0033] Understandably, this solution spatially separates the drive source 2101 from the transmission rod 23, and uses a flexible or rigid transmission component 2104 for power transmission, greatly enhancing the layout flexibility and environmental adaptability of the entire device. The drive source 2101 can be installed on the vehicle body 11 in a location with less vibration and easy heat dissipation and maintenance, without having to be adjacent to a damp, muddy cleaning area. The first drive shaft 2102 and the second drive shaft 2103 are connected by the transmission component 2104, which can be either a drive belt or a chain, forming a long-distance power transmission system. Belt drive has the advantages of simple structure, low cost, good damping and vibration absorption, and slippage protection for the drive source 2101 under overload, making it particularly suitable for harsh working environments. Chain drive has the characteristics of high load-bearing capacity, precise transmission ratio, and no elastic slippage, making it suitable for working conditions requiring the transmission of large torques. Gearbox drive can achieve compact, efficient, and high-precision power transmission. This split-drive design not only optimizes the internal space utilization of the equipment, making the overall structure of the sludge scraping device more compact, but also facilitates centralized control and protection of the drive source 2101, extending its service life. Furthermore, by replacing transmission components 2104 with different transmission ratios, such as pulleys of different diameters or sprockets with different tooth counts, the moving speed of the scraping brush 50 can be easily adjusted to meet the cleaning needs of sludge of varying viscosity, thereby improving the practicality of this solution.

[0034] like Figure 4 As shown, in one feasible embodiment, the second linear movement mechanism 30 includes at least one telescopic rod 31 and a second support member 32. One end of all the telescopic rods 31 is connected to the moving end of the first linear movement mechanism 20, and the second support member 32 is connected to the other end of the telescopic rods 31.

[0035] In this technical solution, the telescopic rod 31 can be either an electric telescopic rod or a hydraulic telescopic rod. In this embodiment, the telescopic rod 31 is a hydraulic telescopic rod. In some examples, two sets of telescopic rods 31 are provided. One end of each set of telescopic rods 31 is connected to the first support member 26, and the second end of each set of telescopic rods 31 is connected to the second support member 32. In some examples, the telescopic direction of the telescopic rod 31 is perpendicular to the moving plane of the first linear moving mechanism 20, so that the telescopic rod 31 can drive the scraper part 50 to move toward the surface to be cleaned.

[0036] Understandably, the second linear movement mechanism 30 is the core actuator for adjusting the position of the scraper 50 in the second direction, which is typically perpendicular to the surface to be cleaned. By providing at least one telescopic rod 31, a stable and controllable lifting or pushing force can be provided to the scraper 50. When two or more telescopic rods 31 are provided, they extend and retract synchronously, jointly supporting the second support 32 to form a stable lifting platform. This ensures the smoothness and levelness of the scraper 50 during lifting and retraction, avoiding tilting or jamming caused by single-point support. Electric telescopic rods are used for the telescopic rods 31, offering advantages such as precise control, rapid response, and easy integration with automated control systems. Automated position adjustment can be achieved through programming. Hydraulic telescopic rods offer advantages such as high output force, robust structure, and strong impact resistance, easily overcoming the significant resistance from viscous sludge. The extension and retraction direction of the telescopic rods 31 is set perpendicular to the moving plane of the first linear movement mechanism 20, i.e., perpendicular to the main moving direction of the scraper 50. This orthogonal arrangement ensures that the movements in the two directions do not interfere with each other, achieving decoupled control of two-dimensional motion. Operators can precisely control the extension length of the telescopic rod 31 based on real-time observation of the silt condition or data fed back from sensors, thereby quickly and accurately adjusting the scraper 50 to the optimal working height, providing good initial conditions for the subsequent elastic connection structure 40 to perform its adaptive function.

[0037] like Figure 4 As shown, in one feasible embodiment, the elastic connection structure 40 includes a third support member 41, a limiting rod 42, and at least one elastic member 43. The third support member 41 has at least one limiting hole, the number of limiting rods 42 matches the number of limiting holes, the limiting rods 42 slide through the limiting holes, one end of the limiting rod 42 is provided with a scraping part 50, and the elastic member 43 is disposed between the third support member 41 and the scraping part 50. The elastic member 43 is used to generate a thrust on the scraping part 50.

[0038] In this technical solution, the sliding connection between the limiting rod 42 and the limiting hole allows the scraper part 50 to have space to move up and down. In some examples, the elastic element 43 is a spring. By placing the elastic element 43 between the third support member 41 and the scraper part 50, the preload of the scraper part 50 can be pushed to adapt to the concavity and convexity of the vehicle bottom, thereby making the scraper part 50 fit better with the bottom of the vehicle body 11.

[0039] Understandably, in this design, the elastic connection structure 40 is pre-compressed and installed between the third support 41 and the scraper 50, continuously generating a downward thrust. This thrust ensures that the scraper 50 always tends to adhere tightly to the surface to be cleaned. When the scraper 50 encounters a small protrusion on the bottom surface of the vehicle body 11, the scraper 50 is pushed upward, compressing the elastic element 43. The elastic element 43 stores energy and generates a larger reaction force, causing the scraper 50 to press over the protrusion. When encountering a depression, the elastic element 43 releases energy, pushing the scraper 50 downward to fill the gap in the depression. In this way, the pre-tension provided by the elastic element 43 can dynamically adapt to the unevenness of the bottom surface of the vehicle body 11, ensuring that the scraper 50 maintains continuous and uniform contact pressure with the surface to be cleaned throughout its working stroke, thereby thoroughly removing the sludge from the uneven areas and significantly improving the thoroughness and uniformity of the cleaning. This structure is simple, reliable, and easy to maintain. By selecting elastic elements 43 with different stiffnesses, the magnitude of the preload can be easily adjusted to adapt to sludge of different hardness or surfaces of different materials to be cleaned.

[0040] like Figure 4 As shown, in one feasible embodiment, the third support member 41 includes a plate 4102 and at least one connecting segment 4101. A limiting hole is formed on the plate 4102. One end of the connecting segment 4101 is connected to the plate 4102, and the other end is connected to the second linear movement mechanism 30, so that there is a gap between the limiting hole position of the plate 4102 and the second linear movement mechanism 30.

[0041] In some examples, the third support member 41 may include a plate 4102 and two connecting segments 4101. The plate 4102 has a limiting hole, and the two connecting segments 4101 are respectively located at both ends of the plate 4102. One end of the connecting segment 4101 is connected to the plate 4102 and the other end is connected to the second support member 32. The length of the connecting segment 4101 is configured to allow the space between the plate 4102 and the second support member 32 to be sufficient to accommodate the limiting rod 42 moving from bottom to top.

[0042] Understandably, this technical solution, by setting the connecting section 4101, creates a necessary installation and movement space between the plate 4102 and the second support member 32 of the second linear movement mechanism 30, providing sufficient extension and retraction stroke for the limiting rod 42 and the elastic member 43. Specifically, when the scraper part 50 is lifted upward, the limiting rod 42 needs to slide upward relative to the plate 4102, while the elastic member 43 is compressed. If there is insufficient space, the upper end of the limiting rod 42 or the elastic member 43 may interfere with or collide with the second support member 32 in the compressed state, thereby limiting the upward movement of the scraper part 50, causing it to be unable to effectively avoid large protrusions, or even damaging the mechanism.

[0043] like Figure 4As shown, in one feasible embodiment, the limiting rod 42 includes a rod body 4201 and a blocking member 4203. The rod body 4201 is slidably inserted into the limiting hole, and the blocking member 4203 is disposed at one end of the rod body 4201 away from the scraper part 50. The size of the blocking member 4203 is configured to prevent the rod body 4201 from passing through the limiting hole.

[0044] Understandably, the elastic element 43 exerts a pushing force on the scraper part 50. While pushing the scraper part 50 outward, the rod 4201 also moves simultaneously. To prevent the rod 4201 from falling out of the limiting hole, a blocking element 4203 is fixedly connected to the upper end of the rod 4201. This blocking element 4203 can be a blocking block or a baffle. This prevents the rod 4201 from accidentally falling out of the limiting hole of the third support member 41, thereby preventing the entire scraper part 50 assembly from separating from the main body of the device.

[0045] like Figure 4 As shown, in one feasible embodiment, an installation member 4202 is provided between the limiting rod 42 and the scraping part 50. The installation member 4202 and the limiting rod 42 are fixedly connected. The installation member 4202 is detachably connected to the scraping part 50. One end of the elastic member 43 is connected to the third support member 41, and the other end is connected to the installation member 4202.

[0046] Understandably, since different vehicle bodies 11 have different internal dimensions, a mounting component 4202 is provided at the bottom of the limiting rod 42 to accommodate different internal dimensions of the vehicle body 11. The mounting component 4202 is used to install scraper parts 50 of different sizes. The specific installation method can be bolt fixing or a slot is provided on the mounting component 4202 to snap the scraper part 50 into the slot, thereby achieving the installation and fixation of the scraper part 50. When dealing with different models and sizes of vehicle bodies 11, or when the scraper part 50 is worn or damaged due to long-term use and needs to be replaced, no modification is required to the entire elastic connection structure 40. Operators only need to prepare scraper parts 50 of various specifications, such as scrapers or scrapers of different widths and shapes, and then quickly install the appropriate scraper part 50 onto the mounting component 4202 by simple bolt tightening, snap-fit ​​connection, or quick-release pins.

[0047] like Figure 1 and Figure 2 As shown, a high-level tippler is provided according to a second aspect of the embodiments of this application. The high-level tippler includes a sludge scraping device as described in any of the above technical solutions.

[0048] The high-level tippler provided in this application embodiment includes a sludge scraping device as described in the above-described technical solution, and therefore possesses all the beneficial effects of the sludge scraping device described in the above-described technical solution.

[0049] In this technical solution, the aforementioned sludge scraping device is integrated into a high-level tipper, forming a fully functional and highly automated material unloading and cleaning system. High-level tippers are mainly used to tip over railway freight cars or large mining cars to unload bulk materials such as coal and ore. After unloading, a large amount of adhering sludge and other wet materials often remain at the bottom of the car body 11. If not cleaned in time, this will not only reduce the effective volume of the car body 11 but may also corrode it, affecting transportation safety. The high-level tipper of this application, through its built-in sludge scraping device, can automatically start the cleaning process after the tipper completes unloading and resets. The first linear movement mechanism 20 drives the scraper 50 to move longitudinally or laterally along the car body 11. The second linear movement mechanism 30 and the elastic connection structure 40 ensure that the scraper 50 can closely adhere to the bottom of the car, achieving comprehensive and efficient cleaning of the residual sludge. The cleaned sludge can be collected and treated centrally through the sludge outlet 12 at the bottom of the car body 11. This integrated design combines the unloading and cleaning processes into one, enabling continuous and automated operations. This significantly reduces vehicle turnaround time, improves overall operational efficiency, and reduces the labor intensity and safety risks associated with manual cleaning.
