Description

Technical Field

[0001] This invention relates to the field of bulk cargo transfer equipment, and more particularly to a hopper equipped with an intelligent dust suppression spray device and intelligent material feeding. Background Technology

[0002] Equipped with an intelligent dust suppression spray system and intelligent feeding, the hopper is a material storage and conveying device used in bulk cargo transfer scenarios. It is widely used in bulk cargo loading and unloading operations in ports, mines, and construction. Its core components include the hopper body, intelligent feeding control mechanism, intelligent dust suppression spray mechanism, and auxiliary drive and detection components. Its main function is to achieve centralized temporary storage and orderly feeding and loading of bulk cargo, and to suppress dust pollution generated during material loading, unloading, and transfer through intelligent spraying. While ensuring material conveying efficiency and improving loading accuracy, it reduces the impact of dust on the working environment and personnel health, meeting environmental protection requirements and high-efficiency production needs.

[0003] However, existing hoppers equipped with intelligent dust suppression spray devices and intelligent material unloading still have many shortcomings in practical applications, making it difficult to meet the high-efficiency and environmentally friendly requirements of large-scale bulk cargo loading and unloading in scenarios such as ports. Specific deficiencies include: Firstly, the level of intelligence in the dust suppression process is low. Most devices still use fixed spray heads for continuous spraying or manual control for start / stop, and cannot precisely coordinate with operations such as grab bucket loading and vehicle receiving. This easily leads to situations where spraying is not timely after dust escapes, or ineffective spraying when there is no operation, affecting dust suppression effectiveness and wasting water and energy resources, making it difficult to meet the strict requirements of port environmental supervision. Secondly, the discharge port is prone to blockage. Sticky bulk cargo or easily agglomerated materials tend to accumulate at the distribution plate and discharge port during the unloading process, leading to blockages, seriously affecting loading efficiency and hindering the overall production plan.

[0004] Therefore, it is necessary to provide a new hopper equipped with an intelligent dust suppression spray device and intelligent material feeding to solve the above-mentioned technical problems. Summary of the Invention

The second mounting base is fixedly connected to the column; the top of both the first and second mounting bases is rotatably connected to a first rotating shaft, and the top of the first rotating shaft is fixedly connected to a spray head; the interior of both the first and second mounting bases is equipped with a swinging assembly, which is used to drive the spray head to swing back and forth to expand the dust suppression coverage area; the interior of the hopper body is fixedly connected to a material distribution plate, the two ends of the material distribution plate are located above the two discharge ports, and both ends of the material distribution plate are equipped with a stirring assembly, which is used to stir the material to prevent the material from clumping and clogging.

[0007] Preferably, the sliding assembly includes a first slider, and the bottom of each of the two slide rails is symmetrically provided with a first groove. Each of the four first grooves is slidably connected to a first slider, and the bottom end of the first slider is fixedly connected to a baffle. In the two slide rails, a first threaded rod is rotatably connected inside one slide rail, and the first threaded rod is threadedly connected to the corresponding two first sliders. A guide rod is fixedly connected inside the other slide rail, and the guide rod is slidably engaged with the remaining two first sliders. The first threaded rod and the guide rod are arranged parallel to each other.

[0008] Preferably, a first drive motor is fixedly connected inside the slide rail on which the first threaded rod is installed, and the output end of the first drive motor is fixedly connected to the first threaded rod to drive the first threaded rod to rotate in both directions.

[0009] Preferably, the oscillating assembly includes turntables, four of which are rotatably disposed inside two first mounting seats and two second mounting seats respectively. The top of each turntable is coaxially and fixedly connected to a first rotating shaft. Each of the four turntables is eccentrically and fixedly connected to a shift post. Each of the first and second mounting seats is slidably connected to a shift ring, which is movably sleeved on the outside of the shift post. The sliding of the shift ring can drive the turntable to rotate through the shift post.

[0010] Preferably, both the first and second mounting bases are rotatably connected to a reciprocating lead screw, and the bottom of each dial ring is fixedly connected to a second slider. The second slider is threadedly connected to the reciprocating lead screw, and the rotation of the reciprocating lead screw can drive the second slider to move the dial ring back and forth. Both the first and second mounting bases are symmetrically fixedly connected to limit posts. The limit posts are arranged along the sliding direction of the dial ring to limit the movement range of the dial ring and avoid excessive sliding that could damage the components.

[0011] Preferably, a second drive motor is fixedly connected inside both the first mounting base and the second mounting base, and the output end of the second drive motor is fixedly connected to the reciprocating lead screw to provide power for the rotation of the reciprocating lead screw.

[0012] Preferably, the agitation assembly includes a drive rod, two drive rods are respectively rotatably disposed between the hopper body and the distribution plate, and a plurality of agitating rods are fixedly connected to the outer wall of the drive rod. The plurality of agitating rods are evenly distributed along the axial direction of the drive rod, and each agitating rod is spaced apart along the circumference of the drive rod.

[0013] Preferably, a third drive motor is fixedly connected inside the material distribution plate. The third drive motor is a dual-axis extension motor, and the two output ends of the third drive motor are fixedly connected to the corresponding drive rods to synchronously drive the two drive rods to rotate.

[0014] Preferably, a connecting rod is fixedly connected to the side of the first mounting base away from the hopper body, and a sensor body is fixedly connected to the top of the connecting rod. The sensor body is used to identify the position and movement of the grab bucket, so as to realize intelligent start and stop control of the two spray heads located at the top of the hopper.

[0015] Preferably, two of the four columns are diagonally arranged and fixedly connected to cameras for monitoring the working environment and material status around the hopper; the middle parts of the multiple columns are fixedly connected by connecting columns to form a stable frame, wherein the bottom of the two connecting columns located on the front and rear sides are fixedly connected to lidar for determining the position of the vehicle to be loaded; radar level gauges are fixedly connected to the back sides of the two discharge ports for real-time detection of the loading material level.

[0016] Compared with related technologies, the hopper equipped with an intelligent dust suppression spray device and intelligent material feeding provided by the present invention has the following beneficial effects: I. Intelligent and precise dust reduction, balancing environmental protection and energy conservation This invention, through the coordinated control of the sensor body and the swing-type spray mechanism, completely changes the crude mode of existing devices that rely on fixed spraying or manual start / stop. The sensor body can accurately identify the position of the grab bucket and the feeding action, realizing real-time linkage between the spray system and the operation process. The spraying automatically starts when the grab bucket is feeding and delays shutting off after the grab bucket leaves, avoiding the problems of untimely spraying after dust dissipation or ineffective spraying when there is no operation. At the same time, the swing component drives the spray head to swing back and forth, which, together with the high-pressure atomizing spray head, greatly expands the dust suppression coverage area. The water mist is fine and has a high coverage rate, which can effectively suppress dust pollution throughout the entire feeding and unloading process, meeting the strict environmental protection requirements of ports, mines and other scenarios, while reducing water and energy waste, achieving the dual goals of environmental protection and energy conservation.

[0017] II. Efficient anti-clogging material feeding improves operational continuity To address the problem of material agglomeration and accumulation causing blockages at the discharge ports of existing hoppers, this invention employs a composite structural design of "material distribution + agitation + precise discharge adjustment." The V-shaped material distribution plate inside the hopper evenly distributes material to both discharge ports, preventing material accumulation on one side. The agitation components at both ends of the distribution plate are driven by a third motor extending from two shafts, synchronously rotating multiple agitator rods to fully cover the ends of the distribution plate and the area above the discharge ports. This effectively breaks up agglomerated materials and sticky bulk materials, facilitating smooth material flow. Simultaneously, the intelligent discharge control mechanism, driven by a servo motor, precisely adjusts the baffle opening and movement speed to adapt to the discharge requirements of materials with different flowability. This prevents blockages caused by excessively rapid discharge or material accumulation, ensuring continuous loading operations, significantly improving overall production efficiency, and avoiding production schedule disruptions due to blockages.

[0018] III. Intelligent linkage throughout the entire process reduces reliance on manual labor. This invention constructs a fully integrated intelligent linkage system encompassing detection, control, and execution. Through sensors, radar level gauges, cameras, and lidar, it collects real-time information on grab bucket position, material level, operating environment, and obstacles, transmitting this data to an external control system. The control system synchronously coordinates dust suppression, material feeding, and agitation mechanisms, automating the start / stop of the spray system, adjusting the spray angle, controlling the material feeding opening, and activating / deactivating the agitation action. The entire operation cycle can be completed without manual intervention. This reduces the intensity of manual operation and human error while improving operational accuracy and safety, making it particularly suitable for large-scale bulk cargo handling scenarios and facilitating intelligent production upgrades.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0023] like Figures 1 to 11As shown, a hopper equipped with an intelligent dust suppression spray device and intelligent material unloading is disclosed. The hopper includes: a hopper body 1, which is the core load-bearing component. Multiple columns 2 are fixedly connected at equal intervals to the bottom of the hopper body 1. The columns 2 support the hopper body 1 and ensure the overall structural stability. Two of the four columns 2, arranged diagonally, are fixedly connected to cameras 27. The cameras 27 monitor the surrounding working environment and material loading / unloading status of the hopper body 1 in real time, facilitating operators to monitor the work progress. The middle part of each column 2 is fixedly connected by connecting columns 28 to form a stable frame. The bottom of the two connecting columns 28 located on the front and rear sides is fixedly connected to a lidar 29. The lidar 29 is used to accurately detect the material spill range and obstacles in the working area to avoid collision accidents during operation. The bottom of the hopper body 1 is symmetrically fixedly connected to a discharge port 3. The back side of each of the two discharge ports 3 is fixedly connected to a radar level gauge 30. The radar level gauge 30 is used to detect the material liquid level height in the hopper body 1 in real time, providing data support for material discharge control.

[0024] It should be noted that the connecting column 28 is made of high-strength steel, which can improve the overall load-bearing capacity of the column 2 and adapt to the weight load of the hopper body 1 after it is full of materials; the radar level gauge 30 adopts a non-contact detection method to avoid direct contact with materials and avoid wear, thus extending its service life.

[0025] like Figures 1 to 5As shown, slide rails 4 are fixedly connected to both sides of the bottom of the two discharge ports 3. Each slide rail 4 has two baffles 5 at its bottom. A sliding assembly is installed inside the slide rail 4, which includes a first slider 11, a first threaded rod 12, a guide rod 13, and a first motor 14. The bottom of the two slide rails 4 is symmetrically provided with first grooves 10. The first sliders 11 are slidably connected in the four first grooves 10. The bottom end of the first slider 11 is fixedly connected to the baffle 5. In one of the slide rails 4, the first threaded rod 12 is rotatably connected inside. The first threaded rod 12 is threadedly connected to the two corresponding first sliders 11. The first motor 14 is also fixedly connected inside the slide rail 4. The output end of the first motor 14 is fixedly connected to the first threaded rod 12 through a coupling. The guide rod 13 is fixedly connected inside the other slide rail 4. The guide rod 13 is slidably engaged with the remaining two first sliders 11, and the first threaded rod 12 and the guide rod 13 are arranged parallel to each other. During operation, the external control system controls the first motor 14 to start based on the material level data detected by the radar level gauge 30 and the location information of the receiving vehicle. The first motor 14 drives the first threaded rod 12 to rotate in both directions. Through the threaded engagement between the first threaded rod 12 and the first slider 11, the baffle 5 is driven to slide along the first slide groove 10. The guide rod 13 guides and limits the first slider 11, ensuring that the baffle 5 moves smoothly. This enables the opening, closing and opening degree adjustment of the discharge port 3, controls the feeding speed and feeding amount, and completes the intelligent feeding operation.

[0026] It should be noted that: the first motor 14 is a servo motor, which can achieve precise speed control, thereby adjusting the moving speed of the baffle 5 to adapt to the feeding requirements of different materials; the surface of the first threaded rod 12 is coated with wear-resistant grease to reduce frictional wear with the first slider 11 and extend the service life of the component.

[0027] like Figure 1 , Figure 2 , Figures 6 to 10As shown, a first mounting base 6 is symmetrically fixedly connected to the top of the hopper body 1, and a second mounting base 7 is symmetrically provided below the discharge port 3. The second mounting base 7 is fixedly connected to the column 2. A first rotating shaft 8 is rotatably connected to the top of both the first mounting base 6 and the second mounting base 7. A spray head 9 is fixedly connected to the top of the first rotating shaft 8. A swing assembly is installed inside both the first mounting base 6 and the second mounting base 7. The swing assembly includes a turntable 15, a deflector 16, a deflector ring 17, a reciprocating screw 18, a second slider 19, a limit post 20, and a second motor 21. The four turntables 15 are respectively rotatably arranged inside the two first mounting bases 6 and the two second mounting bases 7. The top of the turntable 15 is coaxial with the first rotating shaft 8. The four turntables 15 are fixedly connected, with eccentrically fixed pegs 16 at their bottoms. A peg ring 17 is slidably connected inside the first mounting base 6 and the second mounting base 7, and the peg ring 17 is movably sleeved on the outside of the peg 16. A reciprocating screw 18 is rotatably connected inside the first mounting base 6 and the second mounting base 7. A second slider 19 is fixedly connected to the bottom of each peg ring 17, and the second slider 19 is threadedly connected to the reciprocating screw 18. Limiting posts 20 are symmetrically fixedly connected inside each peg ring 17, and the limiting posts 20 are arranged along the sliding direction of the peg ring 17. A second motor 21 is fixedly connected inside the first mounting base 6 and the second mounting base 7. The output end of the second motor 21 is fixedly connected to the reciprocating screw 18 via a coupling. Simultaneously, a connecting rod 25 is fixedly connected to the side of the first mounting base 6 away from the hopper body 1, and a sensor body 26 is fixedly connected to the top of the connecting rod 25. The sensor body 26 is used to identify the position and movement of the grab bucket. During operation, after the sensor body 26 detects the loading action of the grab bucket, it transmits the signal to the external control system. The control system starts the second motor 21 and the spray system. The second motor 21 drives the reciprocating screw 18 to rotate. Through the threaded engagement between the reciprocating screw 18 and the second slider 19, the deflector ring 17 is driven to slide back and forth within the range limited by the limit post 20. The deflector ring 17 drives the turntable 15 to rotate back and forth through the deflector post 16, which in turn drives the first rotating shaft 8 and the spray head 9 to swing back and forth, expanding the coverage area of ​​the spray dust suppression. The water mist sprayed by the spray head 9 can effectively suppress the dust generated during the loading and unloading process. After the sensor body 26 detects that the grab bucket has left, the control system shuts down the spray system and the second motor 21 to achieve intelligent dust suppression and avoid ineffective spraying.

[0028] It should be noted that: the limit post 20 can prevent the dial ring 17 from sliding excessively, causing the dial post 16 to disengage from the dial ring 17, thus ensuring the stable operation of the swing assembly; the spray head 9 adopts a high-pressure atomizing nozzle, which can improve the water mist coverage, enhance the dust suppression effect, and save water resources.

[0029] like Figure 6 and Figure 10As shown, a material distribution plate 31 is fixedly connected inside the hopper body 1. The material distribution plate 31 is used to divert the material to two discharge ports 3. The two ends of the material distribution plate 31 are located above the two discharge ports 3 respectively, and a stirring assembly is installed at both ends of the material distribution plate 31. The stirring assembly includes a drive rod 22, a stirring rod 23 and a third motor 24. The two drive rods 22 are respectively rotatably arranged between the hopper body 1 and the material distribution plate 31. Multiple sets of stirring rods 23 are fixedly connected to the outer wall of the drive rod 22. The multiple sets of stirring rods 23 are evenly distributed along the axial direction of the drive rod 22, and each set of stirring rods 23 is spaced apart along the circumference of the drive rod 22. The third motor 24 is fixedly connected inside the material distribution plate 31. The third motor 24 is a dual-shaft extension motor, and its two output ends are fixedly connected to the corresponding drive rods 22 through couplings. During operation, the external control system synchronously starts the third motor 24, which drives the two drive rods 22 to rotate synchronously, thereby driving the stirring rod 23 to stir the material in the hopper body 1. This can effectively break up sticky bulk materials and materials that are prone to clumping, preventing materials from accumulating and blocking at the distribution plate 31 and the discharge port 3. At the same time, it assists the material to flow to the discharge port 3, improving the material discharge efficiency.

[0030] It should be noted that the third motor 24 adopts a dual-shaft motor, which simplifies the transmission structure, reduces the number of parts, and lowers the equipment failure rate; the stirring rod 23 is made of high-strength alloy material, which can withstand material impact and avoid deformation and damage.

[0031] The working principle of this invention is as follows: Before the equipment is started, the external control system completes the self-test of each component. The camera 27, lidar 29, radar level gauge 30, and sensor body 26 start up synchronously and feed back detection signals. After confirming that each component is normal, the equipment enters the working state. When the grab bucket carries material into the hopper body 1, the sensor body 26 detects the approach signal of the grab bucket and immediately transmits the signal to the external control system. The control system simultaneously starts the second motor 21 and the water pump of the spray system. The second motor 21 drives the reciprocating screw 18 to rotate. Through the threaded engagement between the reciprocating screw 18 and the second slider 19, the deflector ring 17 is driven to slide back and forth along the range limited by the limit post 20. The deflector ring 17 drives the turntable 15 to rotate back and forth through the eccentrically set deflector post 16. The turntable 15 drives the first rotating shaft 8 and the spray head 9 to swing back and forth synchronously. The spray head 9 at the top of the hopper body 1 sprays the dust emission area at the feed inlet. The spray head 9 below the discharge outlet 3 has a pre-set spray range to achieve dust suppression throughout the process. After the sensor body 26 detects that the grab bucket has left, the control system delays for 3-5 seconds to shut down the second motor 21 and the water pump to prevent residual dust from escaping and to avoid ineffective spraying that wastes water resources. After the material enters the hopper body 1, it is diverted by the distribution plate 31 to the two discharge ports 3. At this time, the external control system starts the third motor 24. The third motor 24 drives the two drive rods 22 to rotate synchronously, driving multiple sets of stirring rods 23 to stir the material, break up the sticky material and clumps, and assist the material to flow to the discharge port 3, preventing the material from accumulating and blocking at the end of the distribution plate 31 and the discharge port 3. The radar level gauge 30 monitors the material level in the hopper body 1 in real time. When the material level reaches the preset value and the receiving vehicle stops at the designated position, the lidar 29 confirms that there are no obstacles in the receiving area, and the camera 27 assists in confirming the vehicle position. Then, the control system starts the first motor 14, which drives the first threaded rod 12 to rotate forward. Through the threaded engagement between the first threaded rod 12 and the first slider 11, the two baffles 5 slide synchronously to both sides along the first slide groove 10. The guide rod 13 guides the first slider 11 to ensure that the baffles 5 move smoothly, thus opening the discharge port 3 and allowing the material to fall into the receiving vehicle through the discharge port 3. According to the receiving requirements, the control system adjusts the speed of the first motor 14 to control the opening of the baffles 5, thereby adjusting the feeding speed and feeding amount. During the operation, the camera 27 monitors the material loading and unloading status and the operation of the baffles 5 in real time, and the lidar 29 continuously detects the material spillage range and surrounding obstacles. If any abnormality occurs, it immediately feeds back to the control system, which can urgently shut down the first motor 14 and the discharge port 3, and issue a warning signal at the same time. After the material is fed, the radar level gauge 30 detects that the material level is lower than the preset value. The control system drives the first motor 14 to reverse, which drives the baffle 5 to reset and block the discharge port 3. Then the third motor 24 is turned off, completing a complete intelligent feeding and dust suppression cycle.

[0032] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
