Description

Technical Field

[0001] This invention relates to the field of open-pit mine conveying equipment technology, and more particularly to a flexible combined continuous bulk material handling system. Background Technology

[0002] In the daily operation of open-pit mines, the transportation and storage of bulk materials is an indispensable part of the production process. These bulk materials include, but are not limited to, ores, waste rock, and coal, and their transportation efficiency directly affects the overall production capacity and economic benefits of the mine. However, traditional bulk material transportation methods face many challenges:

[0003] Firstly, traditional bulk material conveying methods often rely on manual operation or simple mechanical equipment, resulting in problems such as limited transport distance, frequent interruptions during transfer, long waiting time, and poor flexibility. These problems not only limit the production capacity of mining enterprises but also increase labor costs and safety risks. They are also detrimental to environmental protection and sustainable development. In addition, there are the following defects: (1) Limited transport distance: Traditional conveying equipment, such as forklifts and trucks, are limited by their load-bearing capacity and travel distance, and often need to be transferred at multiple transfer points. This not only increases transportation costs but also prolongs the overall transportation time of materials from the mining point to the storage point. (2) Low transfer efficiency: During the transfer process, due to the need for manual operation or reliance on simple mechanical equipment, the transfer efficiency is often limited by human factors and equipment performance, resulting in excessively long waiting time for materials at transfer points, which affects the overall production rhythm. (3) Insufficient flexibility: Different open-pit mines have different site conditions, unloading heights, etc., and traditional conveying methods are often difficult to adapt to these changes, resulting in unreasonable stockpile layout and low space utilization. Summary of the Invention

[0004] To address the problems mentioned in the background art, this invention proposes a flexible combined bulk material continuous handling system. This system integrates a bulk material transfer module, a bulk material conveying module, and a bulk material distribution module, achieving fully automated and continuous conveying from the bulk material pile to the final storage location. This system not only solves many drawbacks of traditional conveying methods but also improves the system's flexibility and maintainability through modular design, providing a completely new solution for bulk material conveying and storage in open-pit mines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flexible combined bulk material continuous handling system, including a bulk material transfer module, a bulk material conveying module, and a bulk material distribution module. The bulk material transfer module is used to transfer materials from the bulk material pile over a short distance to the conveying end of the bulk material conveying module. The bulk material conveying module transports materials over a long distance to the bulk material distribution module. The bulk material distribution module flexibly stacks materials longitudinally, laterally, and circumferentially according to the unloading height and site conditions.

[0006] The bulk material distribution module includes a frame, a third tracked walking mechanism, a slewing assembly, a pitch adjustment mechanism, and a tail receiving hopper. It also includes a folding belt conveyor and a belt feeder. The frame is rotatably connected to the track chassis of the third tracked walking mechanism via the slewing assembly. The folding belt conveyor includes a tail assembly and a belt conveyor body. The tail assembly is fixed to the frame. The belt conveyor body includes a first section and a second section. The first section and the second section are foldably connected via the folding mechanism. The end of the first section away from the folding mechanism is hinged to the frame, and the other end is adjustablely connected to the frame via the pitch adjustment mechanism. The tail receiving hopper is located at the top of the belt feeder. One end of the belt feeder is hinged to the frame, and the bottom center of the belt feeder is adjustablely connected to the frame via a first pitch cylinder.

[0007] To further optimize this invention, the following technical solutions may be preferred:

[0008] Preferably, the bulk material transfer module is an independent tipping bucket transport vehicle. A tipping mechanism is provided at the feeding position of the bulk material conveying module. The tipping mechanism includes a tipping frame, and tipping buckets are symmetrically arranged on both sides of the tipping frame. One end of the tipping bucket is hinged to the tipping frame, and a feeder is provided in the middle of the tipping frame. The material in the tipping bucket is periodically flipped into the feeder, and the feeder transports the material to the bulk material conveying module.

[0009] Preferably, the bulk material conveying module includes multiple transfer conveyors connected end to end. Each transfer conveyor includes a transfer conveyor body, and a fourth tracked walking mechanism is provided at the bottom of the transfer conveyor body. The fourth tracked walking mechanism includes a tracked chassis, on which a battery is provided. The middle part of the transfer conveyor body is connected to the tracked walking mechanism through multiple adjustable outriggers, and the multiple adjustable outriggers cooperate to adjust the conveying tilt angle of the transfer conveyor body.

[0010] Preferably, the adjustable outriggers are provided in three sets, two sets on the feeding side and one set on the discharging side. A first connecting part and a second connecting part are provided at the bottom of the conveyor body corresponding to both ends of the tracked walking mechanism. One end of each of the two adjustable outriggers on the feeding side is hinged to the first connecting part, and the other ends are respectively hinged to one end and the top of the tracked walking mechanism. One end of each adjustable outrigger on the discharging side is hinged to the second connecting part, and the other end is hinged to the other end of the tracked walking mechanism. This layout ensures better stability of the conveyor body during operation. Especially in complex terrain or uneven open-pit mines, this design effectively prevents the equipment from tilting or overturning, thereby ensuring the safety and continuity of the transportation process.

[0011] Preferably, the adjustable outriggers include a first outrigger tube and a second outrigger tube that are nested together. Multiple adjusting holes are radially formed at the connection point of the first and second outrigger tubes, and fixing components are installed within these holes. By changing the fixing position of the fixing components, the length of the adjustable outriggers can be changed. This design allows operators to quickly and easily adjust the length of the outriggers according to the actual terrain and needs, thereby adapting to different conveying angle requirements. This not only improves the adaptability and flexibility of the equipment but also reduces the difficulty and complexity of operation. Because the length of the adjustable outriggers can be adjusted as needed, the operating posture and conveying angle of the equipment can be controlled more precisely. This helps reduce the scattering and accumulation of materials during transportation, reducing environmental pollution and damage. Simultaneously, by optimizing the operating posture and conveying angle of the equipment, energy consumption and operating costs can also be reduced, achieving a green and low-carbon transportation method.

[0012] Preferably, the top of the connecting end of the first segment and the second segment is hinged by a pin. The folding mechanism is provided in two sets, which are symmetrically arranged on both sides of the belt conveyor body. Each set of folding mechanisms includes a folding cylinder, a drive plate, and a connecting rod. The drive plate has a first hinge hole, a second hinge hole, and a third hinge hole distributed in a triangular pattern. The fixed end of the folding cylinder is fixedly connected to the first segment, and the telescopic end is hinged to the first hinge hole of the drive plate. The second hinge hole is hinged to the bottom of the first segment at the end away from the frame. The bottom of the second segment near the first segment is provided with a hinge seat. The third hinge hole is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the hinge seat. When the folding cylinder retracts, it can pull the second segment to fold above the first segment. When the folding cylinder extends, it can drive the second segment to open to a position horizontally aligned with the first segment.

[0013] Preferably, the bulk material conveying module includes a flexible conveying frame, with multiple fourth tracked walking mechanisms arranged along the length direction below the flexible conveying frame. The flexible conveying frame includes a conveyor belt, and support rollers are arranged on the flexible conveying frame corresponding to the lower bearing surface of the conveyor belt. A roller support mechanism for suspending the support rollers is provided on the flexible conveying frame. The feed end of the conveyor belt is connected to the unloading hopper of the continuous material processing module, and the discharge end of the conveyor belt is connected to the feed end of the stacking module. The single-point height of the conveying surface of the conveyor belt is adjustable.

[0014] Preferably, the flexible conveyor frame has a head truss one at the feeding end, and a tail roller, a guide chute, and a fixed idler roller are arranged on the head truss along the material flow direction. A tensioning device is also provided at the bottom of the head truss. The conveyor belt is wound sequentially on the tensioning device, the tail roller, and the fixed idler roller. The flexible conveyor frame has a head truss two and a drive roller at the discharging end. The drive roller drives the conveyor belt to rotate. A discharge funnel is provided on the head truss two at the corresponding discharge position.

[0015] Preferably, the idler support mechanism is a flexible rope structure. The conveyor belt includes an upper carrying belt section and a lower return belt section. A first suspension rope is provided along the length direction on the flexible conveyor frame. Multiple suspension frames are spaced apart on the first suspension rope. Idler support ropes are provided along the width direction of the conveyor belt on the suspension frames. Multiple upper idlers are rotatably mounted on the idler support ropes, forming a U-shaped support surface. The carrying belt section is mounted on the U-shaped support surface. A lower idler is also provided on the suspension frame below the upper idler. The return belt section is mounted on the support surface of the lower idler.

[0016] Preferably, the flexible conveyor frame is provided with an anti-deviation structure for preventing the suspension frame from deviating. The anti-deviation structure includes anti-deviation wheel sets located at the four corners of the suspension frame, and the flexible conveyor frame is provided with anti-deviation steel wire ropes that cooperate with the anti-deviation wheel sets.

[0017] The flexible combined bulk material continuous handling system of the present invention brings significant benefits to the field of material transportation technology through its unique flexible connection and free overlapping design:

[0018] 1. Enhanced System Adaptability and Flexibility: This invention, through the flexible connection of the bulk material transfer module, bulk material conveying module, and bulk material distribution module, enables the entire system to be quickly configured and adjusted according to actual terrain and site conditions. This design allows the system to operate effectively in different working environments, such as different heights, distances, and ground conditions, thereby adapting to the ever-changing needs of open-pit mining.

[0019] 2. Improved Transportation Efficiency: Traditional bulk material transportation systems often struggle to adapt to complex and changing operating environments due to their fixed configurations, leading to transportation interruptions or inefficiencies. This invention, through a flexible overlapping method, enables the rapid assembly and disassembly of conveying equipment, significantly reducing interruptions and waiting times during material transfer and improving overall transportation efficiency.

[0020] 3. Reduced operating costs: Due to the system's high configurability, this invention allows for the selection of the most suitable equipment combination based on specific needs, avoiding resource waste. Simultaneously, the flexible connection and free-overlapping design reduces the complexity and cost of maintenance and component replacement, further lowering overall operating costs.

[0021] 4. Improved system reliability: Flexible connections and free overlap capabilities ensure that the system can be quickly adjusted or replaced when encountering equipment failures or operational errors, minimizing the impact of failures on the overall transportation operation and improving the system's reliability and stability.

[0022] 5. Optimized Material Management: The longitudinal, lateral, and circumferential adjustment capabilities of the bulk material distribution module, combined with the flexible application of folding belt conveyors and belt feeders, allow materials to be precisely stacked according to actual needs. This optimized material management not only improves space utilization but also reduces material loss and waste.

[0023] 6. Promotes environmental protection: Reducing material transfer interruptions and waiting times means reducing potential material leaks and spills, thereby mitigating environmental impact. Furthermore, the system's efficient operation also reduces energy consumption, aligning with sustainable development requirements.

[0024] In summary, the flexible combined bulk material continuous transport system of the present invention, through its flexible connection and free overlap characteristics, provides an efficient, economical, reliable and environmentally friendly solution for the continuous and long-distance transportation of bulk materials in open-pit mines, significantly improving the overall performance and efficiency of material transportation.

Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0048] Example 1:

[0049] like Figure 1-17 As shown, a flexible combined bulk material continuous handling system includes a bulk material transfer module 1, a bulk material conveying module 2, and a bulk material distribution module 6. The bulk material transfer module 2 is used to transfer materials from a bulk material pile over a short distance to the conveying end of the bulk material conveying module. The bulk material conveying module transports materials over a long distance to the bulk material distribution module. The bulk material distribution module flexibly stacks materials longitudinally, laterally, and circumferentially according to the unloading height and site conditions. The bulk material transfer module is an independent tipping bucket truck. A tipping mechanism is installed at the feeding position of the bulk material conveying module. The tipping mechanism includes a tipping frame, with tipping buckets symmetrically installed on both sides of the tipping frame. One end of the tipping bucket is hinged to the tipping frame, and a feeder is installed in the middle of the tipping frame. The material in the tipping bucket is periodically flipped into the feeder, which then transports the material to the bulk material conveying module. A lifting platform is also installed at the bottom of the tipping frame. The lifting platform is matched with a liftable support platform and a track wheel mechanism. The lifting platform lifts and moves the tipping frame.

[0050] The bulk material conveying module 2 includes multiple transfer conveyors connected end-to-end. Each transfer conveyor includes a transfer conveyor body 201, with a fourth tracked walking mechanism 202 mounted on the bottom of the transfer conveyor body. The fourth tracked walking mechanism includes a tracked chassis with a battery mounted on it. The transfer conveyor body is connected to the tracked walking mechanism via multiple adjustable outriggers in the middle. These outriggers work together to adjust the conveying angle of the transfer conveyor body. Three sets of adjustable outriggers are installed, two sets on the feeding side and one set on the discharging side. A first connecting part and a second connecting part are installed at the bottom of the conveyor body corresponding to the two ends of the tracked walking mechanism. One end of each of the two adjustable outriggers on the feeding side is hinged to the first connecting part 208, and the other ends of the two adjustable outriggers 207 on the feeding side are respectively hinged to one end and the top of the tracked walking mechanism. One end of each adjustable outrigger on the discharging side is hinged to the second connecting part 209, and the other end of each adjustable outrigger on the discharging side is hinged to the second connecting part 209. At the other end of the tracked walking mechanism, the adjustable outriggers include a first outrigger tube 210 and a second outrigger tube 211 that are nested together. Multiple adjusting holes 212 are radially opened at the connection points of the first and second outrigger tubes. Fixing components are installed in the adjusting holes. By changing the fixing position of the fixing components, the length of the adjustable outriggers is changed. Furthermore, the transfer machine body 201 includes a support frame, on which a conveyor belt 202 is mounted. The conveyor belt 203 is connected to a drive unit. A head funnel 204 is mounted on one end of the support frame corresponding to the conveyor belt, and a tail roller 205 and a guide chute 206 are mounted on the other end of the support frame corresponding to the conveyor belt. The transfer machine body 201 supports the conveyor belt through the support frame. This design makes the entire equipment compact and occupies a small area, suitable for the confined spaces of various open-pit mines. At the same time, the close integration of the conveyor belt and the drive unit ensures the high efficiency and continuity of material transportation, improving the overall production efficiency of the mine.

[0051] The beneficial effects of the above-described transfer conveyor design are mainly reflected in the following aspects:

[0052] (1) The transfer conveyor is designed with a fourth tracked walking mechanism, which enables it to move flexibly in different terrains and working environments, thereby adapting to various complex mining and stockpiling needs. The transfer conveyors are connected end to end to form a continuous material conveying system. The arrangement of the transfer conveyors perpendicular to the transverse belt conveyor enables materials to be transferred from the mining module to the stockpiling module efficiently and accurately, which greatly improves the efficiency and flexibility of material transfer.

[0053] (2) Adjustable conveying angle: By installing multiple adjustable legs in the middle of the transfer conveyor body, and with the design of three sets of adjustable legs (two sets on the feeding side and one set on the discharging side), the conveying angle of the transfer conveyor body can be easily adjusted. This design enables the transfer conveyor to adapt to material transfer needs at different heights and angles, improving the system's adaptability and flexibility. The adjustable legs adopt a design of interlocking first and second leg tubes, and by opening multiple adjustment holes and installing fixing parts at the connection positions, the length of the adjustable legs can be quickly adjusted. This design makes the adjustment process simple and quick, improving work efficiency. The design of the tracked chassis and battery makes the transfer conveyor more stable during movement and operation, reducing material spillage and safety accidents caused by equipment shaking or tilting. By installing first and second connecting parts at both ends of the tracked walking mechanism, and hingedly installing the adjustable legs on these connecting parts, the transfer conveyor body can maintain a stable support state when adjusting the conveying angle, further improving the system's stability and safety.

[0054] The material stacking module includes a frame 601, a third tracked walking mechanism 602, a slewing assembly 603, a pitch adjustment mechanism 604, and a tail receiving hopper 605. It also includes a folding belt conveyor 606 and a belt feeder 607. The frame is rotatably connected to the tracked chassis of the third tracked walking mechanism through the slewing assembly. The folding belt conveyor includes a tail assembly 61 and a belt conveyor body. The tail assembly is fixed to the frame. The belt conveyor body includes a first section 62 and a second section 63. The first section and the second section are foldably connected through the folding mechanism. The end of the first section away from the folding mechanism is hinged to the frame, and the other end is adjustablely connected to the frame through the pitch adjustment mechanism. The tail receiving hopper is located at the top of the belt feeder. One end of the belt feeder is hinged to the frame, and the bottom middle of the belt feeder is adjustablely connected to the frame through a first pitch cylinder. The material conveyed by the material conveying module can be flexibly stacked longitudinally, laterally, and circumferentially according to the unloading height and site conditions.

[0055] The top of the connecting end between the first and second sections is hinged by a pin. Two sets of folding mechanisms are provided, symmetrically installed on both sides of the conveyor body. Each folding mechanism includes a folding cylinder 64, a drive plate 65, and a connecting rod 66. The drive plate has a first hinge hole 67, a second hinge hole 68, and a third hinge hole 69 arranged in a triangle. The fixed end of the folding cylinder is fixedly connected to the first section, the telescopic end is hinged to the first hinge hole of the drive plate, the second hinge hole is hinged to the bottom of the first section at the end furthest from the frame, and the bottom of the second section at the end closest to the first section is hinged to the first section. The conveyor is equipped with a hinged seat. A third hinge hole is hinged to one end of a connecting rod, and the other end of the connecting rod is hinged to the hinged seat. When the folding cylinder retracts, it pulls the second section to fold above the first section. When the folding cylinder extends, it drives the second section to open to a position horizontally aligned with the first section. The optimized design of the folding belt conveyor—through the pin-hinged connection between the first and second sections, and the symmetrically arranged folding and linkage mechanisms on both sides—allows the belt conveyor to flexibly fold and unfold as needed to adapt to different working environments and material stacking requirements. The extension and retraction control of the folding cylinder allows the second section to easily fold above the first section or open to a position horizontally aligned with it. This design not only improves the flexibility of the equipment but also reduces the space occupied when not in use, facilitating storage and transportation. Folding belt conveyors have significant advantages in open-pit mining, especially in situations where site conditions are limited or frequent relocation of material stacking positions is required. They can quickly and flexibly adjust the stacking position and height, improving mining efficiency and reducing transportation costs.

[0056] Example 2:

[0057] The difference between this embodiment and Embodiment 1 is that a flexible conveying system is designed to adapt to terrains with large height differences in long-span transportation. Multiple fourth tracked walking mechanisms 309 are installed along the length of the flexible conveyor frame. The flexible conveyor frame includes a conveyor belt 308, and support rollers are installed on the lower bearing surface of the conveyor belt. A head truss 301 is installed at the feeding end of the flexible conveyor frame. A tail roller 302, a guide chute 303, and a fixed roller 304 are installed on the head truss along the material flow direction. A tensioning device 305 is also installed at the bottom of the head truss. The conveyor belt is sequentially wound around the tensioning device, the tail roller, and the fixed roller. A head truss 310 and a drive roller 311 are installed at the discharging end of the flexible conveyor frame. The drive roller drives the conveyor belt to rotate. A discharge hopper 312 is installed on the head truss 312 corresponding to the discharge position. A roller support mechanism for suspending the support rollers is installed on the flexible conveyor frame. The feeding end of the conveyor belt is connected to the continuous material handling module. The unloading hopper is connected, and the discharge end of the conveyor belt is connected to the feed end of the stacking module. The single-point height of the conveying surface of the conveyor belt is adjustable. The idler support mechanism is a flexible rope structure. The conveyor belt includes a carrying belt section 316 at the top and a return belt section 317 at the bottom. A first suspension rope 307 is installed along the length direction on the flexible conveyor frame. Multiple suspension frames 306 are installed at intervals on the first suspension rope. Idler support ropes 313 are installed on the suspension frames along the width direction of the conveyor belt. Multiple upper idlers 314 are rotatably mounted on the idler support rope, forming a U-shaped support surface. The carrying conveyor belt section is mounted on the U-shaped support surface. A lower idler 315 is also mounted on the suspension frame below the upper idlers. The return conveyor belt section is mounted on the support surface of the lower idler. In addition, an anti-deviation structure 318 for preventing the suspension frame from deviating is installed on the flexible conveyor frame. The anti-deviation structure 318 includes anti-deviation wheel sets installed at the four corners of the suspension frame. Anti-deviation steel wire ropes that cooperate with the anti-deviation wheel sets are installed on the flexible conveyor frame.

[0058] The above design has the following beneficial effects:

[0059] (1) Enhancing conveying stability and efficiency: A head truss is installed at the feeding end of the flexible conveyor frame, along with a tail roller, guide chute, fixed idler roller, and tensioning device. This design ensures the stability and continuity of the material during the conveying process. The tensioning device can adjust the tension of the conveyor belt to prevent belt slippage or excessive slack, thereby improving conveying efficiency. The head truss, drive roller, and discharge hopper at the discharge end further optimize the material discharge process, ensuring that the material can be smoothly and accurately conveyed to the designated location.

[0060] (2) Improve the flexibility and adaptability of the conveyor frame:

[0061] The use of a flexible rope structure as the idler support mechanism makes the conveyor frame more flexible in dealing with complex terrain and long-distance conveying. This design reduces the limitations of traditional rigid support structures on terrain conditions, allowing the conveyor frame to easily cross obstacles such as rivers and mountains. By setting up the first suspension rope, suspension frame, and idler support ropes, all-round support for the conveyor belt is formed. The U-shaped support surface formed by the upper idler effectively bears the weight of the material, while the lower idler provides necessary support for the return belt section, ensuring the stable operation of the conveyor belt.

[0062] (3) Enhance safety and reliability during the transportation process:

[0063] The introduction of anti-deviation structures, such as anti-deviation wheel sets at the four corners of the suspension frame and their matching anti-deviation wire ropes, effectively prevents the suspension frame from shifting or swaying during the conveying process. This not only protects the conveyor belt from damage but also improves the safety and reliability of the entire conveying system. The comprehensive support and anti-deviation design reduces the failure rate and downtime during the conveying process, further enhancing the continuity and efficiency of mining operations.

[0064] (4) Reduced maintenance costs and difficulty: The flexible rope structure and modular design make the maintenance and repair of the conveyor frame more convenient. When a component fails, it can be quickly located and replaced, reducing maintenance costs and difficulty. At the same time, this design also extends the service life of the conveyor frame and reduces the additional costs caused by frequent component replacement.

[0065] like Figure 8 As shown, the suspension frame 306 is a triangular support structure. Due to its inherent stability, the triangular support structure can significantly improve the load-bearing capacity and seismic performance of the suspension frame, ensuring the stable operation of the conveying system under complex geological conditions and harsh weather. The stable support structure reduces component wear and failures caused by vibration and swaying, thereby reducing equipment maintenance costs and downtime. The stable suspension frame reduces the risk of safety accidents caused by equipment failure, ensuring the safety of operators. An inspection robot is installed on the suspension frame 306 directly above the carrying conveyor belt segment 316. The inspection robot can automatically inspect the carrying conveyor belt segment, promptly detect and report potential problems, such as belt wear and misalignment, improving the efficiency and accuracy of inspection. Automated inspection reduces the need for manual inspection, lowers labor costs, and can operate in harsh environments, improving the coverage and safety of inspection. By promptly detecting and handling potential problems, the inspection robot helps improve the reliability and stability of the entire conveying system.

[0066] Example 3:

[0067] like Figure 9As shown, both the upper idler roller 314 and the lower idler roller 315 are arranged in a ring, forming a cylindrical conveying channel with the carrying belt section and the return belt section. Whether both the upper and lower idler rollers are arranged in a ring, or the upper idler rollers are arranged in a ring while the lower idler rollers are arranged horizontally, a cylindrical conveying channel can be formed. This design helps to better support and guide the belt, reduce belt deviation and wear during the conveying process, and improve conveying efficiency.

[0068] Example 4:

[0069] like Figure 11 As shown, the upper idler roller 314 is arranged in a ring, and the lower idler roller 315 is arranged horizontally. The bearing belt section forms a cylindrical conveying channel. The stable conveying channel design helps to reduce vibration and noise during the conveying process and improve the stability and reliability of the entire system.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0071] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
