Description

Technical Field

[0001] The present invention relates to the technical field of bulk material discharging equipment, and particularly relates to an AI automatic loading device. Background Art

[0002] In a factory area, granular or powdered bulk materials such as sand and gravel aggregates, ores, cement clinker, and lime are mostly stored in large silos. When in use, the silo is opened, and the materials are transported onto a transport vehicle for transfer.

[0003] Transport vehicles are generally divided into tank trucks and dump trucks (with a truck bed), and different types of vehicles are used to transport different materials. When using a tank truck, more attention needs to be paid to the alignment problem between the filling port and the discharging pipe. If the alignment is not correct, problems such as material leakage and spilling will occur. The truck bed of a dump truck spreads out, and the docking range with the discharging pipe is wider, making the discharging more convenient. Therefore, many enterprises use dump trucks for transportation.

[0004] When a dump truck is receiving materials, due to being in an open state, the impact of the material discharging is likely to generate dust. The generation of dust not only causes material loss, with the dust loss rate reaching 0.5% - 3%, resulting in cost loss, but also the dust flying and falling on the equipment easily leads to mechanical wear and jamming, an increased risk of circuit short - circuit, and more safety problems. In addition, the cleaning of dust not only increases the burden on the staff (manual cleaning), equipment cost (purchasing dust - cleaning equipment), but also the time occupied by cleaning also occupies the filling time, affecting the overall filling efficiency. Dust also has a serious impact on the physical health of the staff.

[0005] Therefore, when receiving materials and loading the truck, it is necessary to timely handle the dust. Generally speaking, the dust suppression methods mostly use spray dust suppression or negative - pressure dust removal. Spray dust removal is likely to increase the humidity of the material storage environment, making the materials more likely to get damp and deteriorate or agglomerate. Therefore, most enterprises prefer negative - pressure dust removal.

[0006] However, for a dump truck, when discharging materials, the materials gush out from the discharging port of the silo in a concentrated manner. Among them, many of the doped dust impurities will only disperse after falling into the truck bed and then can be separated. But at this time, dust has already been generated, and even through negative - pressure adsorption, the dust removal effect will be reduced.

[0007] Therefore, the present invention provides an AI automatic loading device that can better suppress dust when a dump truck is receiving materials. Summary of the Invention

[0042] The following will be combined with the attached embodiment of the present invention Figure 1-16 , the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] Embodiment 1, in order to solve the problem that the dust suppression effect of the negative pressure dust removal system is poor when the bucket car 5 is loaded, this embodiment provides an AI automatic loading device, including: a silo 6, a connecting pipe 7, and a discharge pipe 8 that are sealed and connected in sequence from top to bottom; A mounting ring 21 is rotatably mounted in the connecting tube 7, a foldable material distribution hopper 22 is arranged on the mounting ring 21, a bendable connecting piece 23 is connected to the upper end of the material distribution hopper 22, the end of the connecting piece 23 is fixedly connected to the inner wall of the connecting tube 7, a support rod 24 for supporting the connecting piece 23 is radially slidably mounted on the connecting tube 7, the support rod 24 moves horizontally synchronously with the folding and unfolding of the mounting ring 21, so as to open the material distribution hopper 22 upward; A coaxially arranged negative pressure tube 27 is suspended outside the connecting tube 7, and a plurality of air pipes 28 are arranged on the inner wall of the negative pressure tube 27. An air port 29 corresponding to the air pipes 28 is arranged on the outer wall of the connecting tube 7. A sealing ring 18 is rotatably mounted on the outer wall of the connecting tube 7, and the sealing ring 18 blocks the air port 29 as the mounting ring 21 is folded.

[0044] Principle details of this embodiment: The silo 6 is suspended by a frame (a mounting bracket formed by welding or bolting steel, not shown in the drawings). 4 in the drawings only shows the lower part of the silo 6, not the complete silo 6. Figure 1Shown is a schematic diagram of the docking of the complete silo 6 with the connecting pipe 7 and the discharging pipe 8, and the discharging pipe 8 is in a stretched state and docked with the trolley 5. The feeding port of the silo 6 is connected with a feeding component, such as a screw conveyor, which feeds materials into the silo 6 for bulk material storage. The docking part between the feeding port of the silo 6 and the feeding component is sealed, such as by setting a sealing cover, which can prevent external dust and water vapor from entering and polluting the materials, and also avoid the overflow of the materials in the silo 6 due to the influence of weather such as strong winds. The discharging port of the silo 6 is of a hopper-shaped structure to facilitate the aggregation of materials. A first bin valve 30 is provided at the discharging port of the silo 6. The first bin valve 30 includes a first connecting rod rotatably installed at both ends of the discharging port of the silo 6. An arc-shaped plate is fixedly connected to the ends of the two first connecting rods. The bottom end of the lower discharging port of the silo 6 is an arc adapted to the arc-shaped plate. A first telescopic rod is rotatably installed on the side wall of the silo 6. The first telescopic rod is any one of a hydraulic rod 15, a pneumatic rod 15, and an electric telescopic rod; the extending end of the first telescopic rod is rotatably connected to the side wall of the arc-shaped plate. By extending the first telescopic rod, the deflection of the arc-shaped plate is controlled, thereby controlling the opening and closing of the discharging port of the silo 6.

[0045] Outer eaves are provided at the upper end of the connecting pipe 7 and the side wall of the silo 6. The outer eaves of the two are connected by bolts, and a sealing gasket is provided at the connection contact surface to achieve the sealed docking between the connecting pipe 7 and the discharging port of the silo 6. The outer eaves of the silo 6 are arranged above the first telescopic rod, so as to completely cover the first bin valve 30.

[0046] The discharging pipe 8 is a telescopic pipe, and the telescopic characteristics of the discharging pipe 8 are used to achieve the lifting docking with the car hopper; the discharging port of the discharging pipe 8 is a rigid pipe hopper, which serves as a connecting member for lifting drive. Multiple groups of second telescopic rods (the same as the first telescopic rod, two groups are set in the attached drawing, symmetrically arranged on both sides of the discharging pipe 8, providing two-point support to avoid the problem of side deviation and instability caused by single-sided connection) are fixed on the outer wall of the connecting pipe 7. The second telescopic rods are arranged in an inverted manner; the extending ends of the second telescopic rods are connected to the rigid discharging port of the discharging pipe 8.

[0047] The negative pressure pipe 27 is arc-shaped and arranged around the connecting pipe 7. The end of the negative pressure pipe 27 is docked with a negative pressure device, such as a pump (vacuum pump, blower), a piston-type negative pressure machine and other devices, to provide negative pressure to adsorb flying dust. Multiple air pipes 28 are arranged at intervals on the inner wall of the negative pressure pipe 27. The air pipes 28 are arranged towards the connecting pipe 7, and air ports 29 corresponding to the air pipes 28 one by one are provided on the outer wall of the connecting pipe 7.

[0048] However, part of the slag only falls into the truck bed, and the impact causes dust to splash and raise dust, resulting in a poor negative pressure dust removal effect. Therefore, in this solution, a device for breaking up the falling materials is also provided in the connecting pipe 7. After the materials are broken up, the gaps between the materials increase, and more slag leaks out, making it easier for the slag to be sucked away by the negative pressure, thereby improving the dust removal effect. The component includes a rotating shaft 17, which is rotatably mounted on the outer wall of the connecting pipe 7, and the rotating shaft 17 is located on the side of the connecting pipe 7, and the rotating shaft 17 is not arranged along the radial direction of the connecting pipe 7, and the end of the rotating shaft 17 passes through the connecting pipe 7 and extends to the outside, and the rotating shaft 17 is driven by an external driving device (telescopic rod or motor) and can rotate forward and reverse. A mounting ring 21 is fixed on the side wall of the rotating shaft 17 facing the axis of the connecting pipe 7, and a material distribution hopper 22 is arranged on the mounting ring 21. The material distribution hopper 22 is a wear-resistant and impact-resistant diamond-patterned metal net bag, a wear-resistant and impact-resistant twill-woven nylon cloth bag, or a metal net bag woven with a metal chain (the structure refers to the nine-section whip). Both the metal net bag and the cloth bag can be flexibly deformed to achieve the purpose of folding and shrinking.

[0049] The upper end of the material distribution hopper 22 is connected to a connecting piece 23 , which is any one of a non-elastic pull rope (such as a nylon rope), a steel wire, a steel strand, and a steel cable; the end of the connecting piece 23 is fixed to the inner wall of the connecting pipe 7 .

[0050] A plug sleeve is inserted into the side wall of the connecting pipe 7, and the plug sleeve penetrates the side wall of the connecting pipe 7. The plug sleeve is arranged toward the axis of the connecting shaft, and the plug sleeve is located above the top of the expanded material distribution hopper 22. A support rod 24 is installed in the plug sleeve for horizontal sliding. The support rod 24 moves horizontally synchronously with the folding and expansion of the mounting ring 21, and then provides stable support for the expansion of the material distribution hopper 22. A guide hole is provided at the end of the support rod 24, and the connecting piece 23 passes through the guide hole to prevent the connecting piece 23 from being separated from the support rod 24.

[0051] According to the above technical solution, this solution has two usage states: When the material stored in the silo 6 is finely crushed ore or other materials, the sub-hopper 22 is unfolded to disperse the granular materials and leak out the slag: the rotating shaft 17 is driven to rotate counterclockwise, and the rotating shaft 17 drives the mounting ring 21 from the vertical folding state to the horizontal state; at this time, the support rod 24 is synchronously inserted into the connecting pipe 7 until the guide hole is located directly above the sub-hopper 22. The support rod 24 presses against the connecting piece 1 23, so that the connecting piece 1 23 is tight and pulls the sub-hopper 22, thereby opening the sub-hopper 22. In this way, after the bin valve 1 30 of the silo 6 is opened, the material falls and impacts the sub-hopper 22, and is dispersed by the sub-hopper 22 (the net bag and the cloth bag can not only disperse the material, but also the slag can pass through the hole to separate the slag from the material, which is more convenient for negative pressure suction and dust removal), so that more slag leaks out, which is convenient for negative pressure suction.

[0052] When the material stored in the silo 6 is powdery material such as cement, dispersing the material at this time will increase the flying dust. Therefore, the distributing hopper 22 is folded and stored: the driving rotating shaft 17 rotates clockwise, and the rotating shaft 17 drives the mounting ring 21 to change from the horizontal unfolded state to the vertical state; at this time, the support rod 24 gradually moves outwards from the connecting pipe 7, and the distributing hopper 22 is folded. At this time, the material no longer falls on the distributing hopper 22.

[0053] In a further embodiment of this solution, in order to prevent the powdery material from falling into the air pipe 28 during loading, resulting in material leakage and loss, it is necessary to block and cut off the air duct on the air pipe 28 and the connecting pipe 7 during this process. Therefore, a sealing ring 18 is rotatably mounted on the outer wall of the connecting pipe 7. The sealing ring 18 is provided with air ducts corresponding to the air ports 29 one by one, and is also provided with a notch for the rotating shaft 17 to pass through. A guiding groove 19 is provided on the outer wall of the sealing ring 18, and a swing rod 20 rotatably coaxial with the mounting ring 21 is provided outside the connecting pipe 7. A slider inserted into the guiding groove 19 is provided at the end of the swing rod 20.

[0054] The guiding groove 19 is any one of a vertical groove, an inclined groove, a spiral groove, a vertical groove, and a combination of a spiral groove extending towards the support rod 24, provided that the swing rod 20 can be deflected to abut against the guiding groove 19 to drive the sealing ring 18 to rotate.

[0055] According to the above technical solution: When the rotating shaft 17 rotates counterclockwise, the swing rod 20 rotates counterclockwise synchronously. The slider at the end of the swing rod 20 will abut against the guiding groove 19, driving the sealing ring 18 to rotate counterclockwise. When the mounting ring 21 is in the horizontal state and the air port 29, the air duct, and the air pipe 28 are aligned, the inside of the connecting pipe 7 is communicated with the negative pressure pipe 27, and the flying dust can be adsorbed by negative pressure.

[0056] When the rotating shaft 17 rotates clockwise, the swing rod 20 rotates clockwise synchronously. The slider at the end of the swing rod 20 will abut against the guiding groove 19, driving the sealing ring 18 to rotate clockwise. When the mounting ring 21 is in the vertical state, the air port 29 is misaligned with the air duct and the air pipe 28, and the air pipe 28 is blocked, thus preventing the material from entering by mistake.

[0057] Preferably, a pipe seat corresponding to the air pipe 28 one by one is also provided as an auxiliary support for the air pipe 28. The pipe seat is provided with a through hole, and the air pipe 28 is inserted into the through hole of the pipe seat. A sealing ring in close fit is provided between the through hole of the pipe seat and the sealing ring 18. The sealing connection between the air pipe 28 and the sealing ring 18 is realized through the sealing ring, avoiding air leakage and overflow.

[0058] In a further embodiment of this solution, in order to realize the matching relationship of the synchronous movement of the support rod 24 and the mounting ring 21, a bendable connecting member two 25 (same as the connecting member one 23) is provided on the slider, and the other end of the connecting member two 25 is connected to the end of the support rod 24 extending outside the connecting pipe 7.

[0059] Preferably, the lower end of the second connecting member 25 can also be fixed to the end of the swing rod 20, and is pulled by the rotation of the swing rod 20, thereby driving the movement of the support rod 24.

[0060] According to the above technical solution: When the rotating shaft 17 rotates counterclockwise, the slider rotates counterclockwise around the axis of the rotating shaft 17 as the swing rod 20 rotates. The slider pulls the support rod 24 through the second connecting member 25, so that the support rod 24 gradually extends into the connecting pipe 7.

[0061] When the rotating shaft 17 rotates clockwise, the slider rotates clockwise around the axis of the rotating shaft 17 as the swing rod 20 rotates. The second connecting member 25 becomes slack and no longer pulls the support rod 24, and the support rod 24 loses the pulling braking force. When the mounting ring 21 rotates clockwise and turns to the vertical, the first connecting member 23 is pulled by the hopper 22, and the support rod 24 is pushed to move out of the connecting pipe 7, thereby realizing the folding of the hopper 22.

[0062] Preferably, an elastic member 13 is provided between the end of the support rod 24 extending outside the connecting pipe 7 and the outer wall of the connecting pipe 7, such as a spring (one end of the spring is fixed on the outer wall of the connecting pipe 7 and the other end is fixed on the outer end of the support rod 24). Due to the pulling of the elastic member 13, the support rod 24 has a tendency to move out of the connecting rod, and the first connecting member 23 does not need to pull, so that the hopper 22 is involved in the force.

[0063] Preferably, a shaft seal is provided between the support rod 24 and the socket, such as a rubber sleeve is provided in the socket to achieve sealing.

[0064] Embodiment 2, the materials are accumulated in the silo 6. Especially for powdery materials such as cement, it is very easy to form lumps, which affects the feeding state; and even for granular materials, it is easy to form arches and block at the hopper-shaped feeding port, which affects the feeding. Therefore, it is necessary to break up the materials in the silo 6 to facilitate feeding. Generally speaking, many factories will use equipment such as vibrators to vibrate the silo 6 to disperse the lumped materials and accelerate the discharge of materials; but this is also very easy to make the components installed by bolts loose, affecting the operation stability and safety.

[0065] Therefore, in this embodiment, a socket penetrating the side wall of the silo 6 is fixed on the side wall at the lower end of the silo 6, and a crushing paddle 9 is rotatably installed in the socket. The crushing paddle 9 includes a stirring shaft, and a plurality of collar rings are detachably installed at intervals along the axial direction of the stirring shaft. Each collar ring is annularly provided with a plurality of stirring teeth, and the decentralized design facilitates single replacement after damage. The stirring teeth of the crushing paddle 9 are inserted into the silo 6 as the socket is inclined, and the driving end of the crushing paddle 9 extends outside the silo 6 (extends outside the connecting pipe 7 in the drawing). By driving the crushing paddle 9 to rotate, the materials at the bottom of the silo 6 are stirred, and the lumped and arched materials are broken up to facilitate feeding.

[0066] Preferably, a drive shaft 10 is rotatably installed outside the connecting pipe 7. A threaded section 11 is provided in the middle of the drive shaft 10. The upper end of the drive shaft 10 is connected to the shaft end of the crushing paddle 9 through a universal joint 14. A drive block 12 is threadedly installed on the threaded section 11. A guide hole is provided on the side of the drive block 12, and a guide post (the guide post can be fixed on the frame or on the outer wall of the connecting pipe 7) fixedly arranged relative to the connecting pipe 7 is inserted into the guide hole. Elastic members 13 are provided at both ends of the threaded section 11 on the drive shaft 10 and cooperate with the drive block 12. The elastic members 13 are springs. A pressure rod 15 is rotatably installed on the side wall of the drive block 12. The end of the pressure rod 15 is rotatably connected to a rocker 16 that rotates coaxially with the swing rod 20. The pressure rod 15 and the rocker 16 form a crank-slider mechanism. A drive section is provided above the upper elastic member 13 on the drive shaft 10, and the drive end is connected to an external motor (not shown in the drawing, only a sprocket is shown) through a chain drive.

[0067] According to the above technical solution: When the material stored in the silo 6 is fine crushed ore or other materials, the motor drives the drive shaft 10 to rotate clockwise through the chain drive: the drive shaft 10 drives the crushing paddle 9 to rotate clockwise through the universal joint 14, thereby stirring the material and realizing the dispersion of caking and arching. When the drive shaft 10 rotates clockwise, the drive block 12 will descend until the drive block 12 is separated from the threaded section 11. At this time, the drive block 12 is pushed up by the lower elastic member 13 and will not descend anymore. The descent of the drive block 12 will press down the rocker 16 through the pressure rod 15, and the rocker 16 drives the rotating shaft 17 to rotate counterclockwise. The rotating shaft 17 drives the mounting ring 21 to change from the vertical state to the horizontal state. The support rod 24 is gradually pulled into the connecting pipe 7 by the connecting member two 25, and is stretched straight against the connecting member one 23 to pull the distributor 22, thereby opening the distributor 22 and using the hopper-shaped structure to achieve the purpose of diverting the material. When the rotating shaft 17 rotates counterclockwise, the swing rod 20 rotates counterclockwise synchronously. The slider at the end of the swing rod 20 will abut against the guide groove 19 and drive the sealing ring 18 to rotate counterclockwise. When the mounting ring 21 is in the horizontal state and the air port 29, the air passage, and the air pipe 28 are aligned, the inside of the connecting pipe 7 communicates with the negative pressure pipe 27, and fly dust can be adsorbed by negative pressure.

[0068] When the material stored in the silo 6 is powdered material such as cement, the motor drives the drive shaft 10 to rotate counterclockwise through chain drive: the drive shaft 10 drives the crushing paddle 9 to rotate counterclockwise through the universal joint 14, which can continue to stir the material to achieve the breakup of caking and arching. When the drive shaft 10 rotates counterclockwise, it will drive the driving block 12 to rise. Under the upward pushing action of the elastic member 13 below, after the threads on the inner wall of the driving block 12 are engaged with the threads of the threaded section 11, the driving block 12 is combined with the threaded section 11, thereby driving the driving block 12 to rise. When the driving block 12 rises, it will pull the rocker 16 through the pressure rod 15, thereby driving the rotating shaft 17 to rotate clockwise. The rotating shaft 17 drives the mounting ring 21 to change from a horizontal state to a vertical state, and the distributing hopper 22 folds, no longer dispersing the material, avoiding more serious dust emission caused by excessive dispersion of the powdered material. When the rotating shaft 17 rotates clockwise, the swing rod 20 rotates clockwise synchronously, and the slider at the end of the swing rod 20 will abut against the guide groove 19, driving the sealing ring 18 to rotate clockwise. When the mounting ring 21 is in a vertical state, the air port 29 is misaligned with the air duct and the air pipe 28, and the air pipe 28 is blocked, thus preventing the material from entering by mistake.

[0069] Preferably, a one-way output structure is provided at the upper end of the drive shaft 10, such as an idler gear one-way transmission mechanism. An input gear is provided at the upper end of the drive shaft 10, and two one-way gears rotatably mounted on the connecting pipe 7 are meshed with the input gear at intervals. One of the one-way gears is meshed with a reversing gear rotatably mounted outside the connecting pipe 7, and the other one-way gear and the reversing gear jointly mesh with an output gear, and the output gear is fixed to the end of the crushing paddle 9. In this way, no matter whether the drive shaft 10 drives the input gear to rotate forward or backward, the rotation direction of the output gear is always the same, thereby driving the crushing paddle 9 to always rotate in one direction. At this time, the stirring teeth of the crushing paddle 9 can be bent and the ends are sharp, which is convenient for breaking up caking and arching.

[0070] In Embodiment 3, in order to achieve precise control of the material discharge, a weighing system is also provided. The weighing system includes a weighing platform 32, and the weighing platform 32 is arranged on a scale (the scale is not shown in the drawings); and it is directly weighed by the scale. A hopper 26 is provided on the weighing platform 32, and the lower end of the hopper 26 is in a funnel shape. A bin valve two 31 is provided at the lower discharge port of the hopper 26, and the structure of the bin valve two 31 can be the same as that of the bin valve one 30; or it is another structure, which is a double-opening bin door. The two bin doors are symmetrically rotatably mounted at the lower end of the hopper 26, and connecting rods are rotatably connected to both ends of the two bin doors. The upper ends of the two connecting rods of the two bin doors are jointly rotatably connected to a telescopic rod three (same as the telescopic rod one).

[0071] The material discharge pipe 8 is arranged on the weighing platform 32 to cover the hopper 26, and a flexible pipe is provided between the connecting pipe 7 and the upper port of the hopper 26.

[0072] According to the above technical solution: During blanking, the second bin valve 31 is closed and the first bin valve 30 is opened. The material first falls into the hopper 26. After the hopper 26 is full, the first bin valve 30 is closed to stop blanking. After obtaining stable weight data, the second bin valve 31 is opened and the material falls into the truck hopper. Then it repeats. Thus, accurate material data is obtained.

[0073] In Example 4, there are many problems during the filling process. For example, the parking position of the hopper truck 5 is not standard, resulting in misalignment between the blanking pipe 8 and the truck hopper and material spillage. This requires readjusting the position of the tanker truck, which not only affects the filling efficiency but also the subsequent overall logistics scheduling plan. In existing scheduling and adjustment systems, most rely on the driver to manually control and adjust the position of the tanker truck, which is not only troublesome and inefficient but also has poor docking accuracy. Therefore, a positioning system is needed to show the driver the position status of the truck hopper and the blanking pipe 8 in real time, facilitating accurate alignment of the material inlet and improving the adjustment efficiency.

[0074] The positioning system in this solution is a 3D radar positioning system, including: (1) 3D contour scanning lidar 4 Hardware configuration: The selected radar model is Velodyne VLP-32C (32-line lidar); the scanning frequency is 20Hz, the vertical field of view is ±15°, and the horizontal field of view is 360°; the auxiliary device is a pan-tilt unit to achieve multi-angle dynamic scanning That is, multiple pan-tilt units are arranged at intervals in Lane 1, and one 3D contour scanning lidar 4 is installed on each pan-tilt unit. Through the cooperation of multiple 3D contour scanning lidars 4, the internal environment of Lane 1 and the body of the hopper truck 5 are continuously scanned with 360° rotation. Each frame generates approximately 1.2 million point cloud data. Using the TOF (Time-of-Flight) ranging principle (ranging accuracy ±3cm), IMU (Inertial Measurement Unit) data is synchronously collected to compensate for vehicle vibration errors. Then, through the Bluetooth communication module, the collected information is transmitted to the terminal in the monitoring room (usually a computer). The PCL (Point Cloud Library) is used for point cloud denoising and ground segmentation. The plane features of the carriage are extracted through the RANSAC algorithm, and the ICP (Iterative Closest Point) algorithm is used to achieve multi-frame point cloud registration to construct data model information. Then, through modeling software (not limited to AutoDesk ReCap Pro 2023), a standardized BIM model (IFC format) is generated, and the calculation error of the carriage volume is output: <0.5%.

[0075] With the cooperation of multiple 3D contour scanning lidars 4, the internal environment of the lane 1 and the body of the skip car 5 are continuously scanned in a 360° rotation. By continuously monitoring the changes, the system can accurately identify the position, shape and material accumulation state of the skip car 5, providing accurate data support for subsequent state control.

[0076] (2)Level radar Hardware configuration: The selected radar model is SICK LMS511 (77GHz millimeter-wave radar, detection range: 0.1 - 80m, resolution 1cm) That is, it is fixedly installed by bolts on the side of the blanking pipe 8 and installed from the top in a top-down view, with a scanning angle of 110°. It continuously detects the height of the material level in the carriage, and transmits the obtained picture information of the material accumulation height in the hopper to the monitoring room through the Bluetooth communication module; when the material level height in the carriage reaches the set height, it gives a voice broadcast through the sound column / electric horn to guide the driver to move the vehicle.

[0077] (3)Laser ranging Hardware configuration: The selected ranging device is KEYENCE IL-300 infrared laser rangefinder.

[0078] That is, infrared laser rangefinders are arranged on both sides of the blanking pipe 8 on the weighing platform 32. Double-beam differential measurement is used to eliminate vibration interference, and it is linked with the telescopic rod for two-way control, which is used to control the rising / falling distance of the blanking port.

[0079] Preferably, contact type travel switches are arranged on both side walls of the hopper in the width direction of the skip car at the lower end of the blanking pipe 8. The contact type travel switches are in contact with the skip car truss to control the stop of the blanking pipe 8 in the descending position, so as to prevent the blanking pipe 8 from colliding with the skip car.

[0080] (4)Vehicle guidance system It includes a voice module (such as a sound column, an electric horn, a speaker, etc.), a display screen, and a three-color warning light that are communicatively connected to the monitoring system and the radar system.

[0081] The vehicle contour is detected by the 3D contour scanning lidar 4, and the position state between the skip car 5 and the blanking pipe 8 is prompted to the driver through devices such as voice, traffic lights, and electric bells, and is displayed in real time through the display screen, prompting the driver to adjust the vehicle position, facilitating the adjustment of the vehicle position, and ensuring the loading accuracy and efficiency.

[0082] (5)Scanning system 2, license plate recognition system 3.

[0083] For the inbound scanning and authentication system, the basic scanning device is a Zebra DS9308 industrial-grade scanning gun, which uses a two-dimensional code encoded by Data Matrix to obtain the blanking document, including the time stamp, operator, and material batch number.

[0084] The license plate recognition system 3 uses a camera for scanning, adopts a CRNN (Convolutional Recurrent Neural Network) model, interfaces with a database, and recognizes the license plate information of vehicles after factory area authentication. (For specific reference, see the parking lot barrier.) (6) Automatic control system The PLC control programmer (concentrated in the computer) receives the data transmitted by the radar and the monitor, analyzes it through AI algorithms, processes and analyzes the radar point cloud data, and extracts key feature information. By comparing the vehicle contour with the preset loading standard, the system can automatically adjust the loading strategy to ensure uniform material loading without overflow. At the same time, this technology can also monitor the volume change of the material during the loading process in real time to achieve accurate metering.

[0085] (7) Data management system The database records and saves the loading data in real time, enabling remote data upload and automated management.

[0086] Specifically: Below the silo 6 is the material receiving area, and the space is demarcated by columns or scaffolding. Cameras are installed at the vehicle entrance, exit, and inside the material receiving area. In particular, there is more than one camera installed inside the material receiving area to obtain the position and status of the trolley 5 in real time and retain the video.

[0087] A voice broadcast system, such as an electric horn or a sound column, is installed at the exit of the material receiving area to broadcast in real time whether the parking status of the trolley 5 is qualified.

[0088] A display screen is installed on the side of the exit of the material receiving area. The display screen is communicatively connected to the camera to show the parking status to the driver in real time.

[0089] At least one convex-concave mirror is installed in the material receiving area to facilitate the driver to observe the position relationship between the feeding pipe 8 and the car hopper by himself.

[0090] Multiple 3D contour scanning lidars 4 are installed at intervals in the material receiving area to scan the loading site in real time. By continuously monitoring the changes, the system can accurately identify the vehicle position, shape, and material accumulation status, providing accurate data support for subsequent loading control.

[0091] Light barriers are installed in front of and behind the lane 1 to obtain accurate signals for the trolley 5 to enter and exit the warehouse.

[0092] A weighbridge is also installed in the lane 1 and cooperates with the weighing platform 32 for dual-stage quantity control to improve the accuracy of the feeding quantity control.

[0093] According to the above technical solutions: Before the vehicle enters the factory area, it scans the code for authentication, and enters the basic information of material loading through the Wed terminal of the internal factory system, completing processes such as placing an order and issuing a bill (including information such as material type, material quantity, timestamp, operator, material batch number, etc.); the vehicle enters the warehouse in sequence, and the license plate is recognized to prevent false recognition of vehicle loading.

[0094] After the trolley 5 enters the warehouse, it is scanned by both the radar and the monitoring system to obtain detailed position information; then, through voice broadcast and monitoring display, the driver's location is prompted and the orientation is adjusted.

[0095] After the material outlet is docked, the material is discharged. The weighbridge cooperates with the weighing platform 32 for dual-stage quantity control to improve the accuracy of the discharged material quantity control.

[0096] The trolley 5 is longer than the material discharge pipe 8. After detecting that the height of the material at the front-side discharge position reaches the limit value, the material discharge stops; then, the driver is prompted by voice broadcast to drive the trolley 5 forward and the approximate position of the forward movement, so that the next receiving position of the trolley bucket is aligned with the material discharge pipe 8 again, and then the material receiving continues until the trolley bucket is full or reaches the material order quantity.

[0097] During the material discharge process, the opening range of the silo gate can be controlled (fully open gate, half-open gate and other states) to control the material discharge speed according to different vehicle types.

[0098] After the loading is completed, equipment such as the material discharge pipe 8 resets and suspends, and then the driver drives the vehicle out of the lane 1.

[0099] The driver combines the scanned bill with the bill of the actual data after the material discharge to generate a loading log, and the log is uploaded to the database for root storage, which is convenient for subsequent analysis and management.

[0100] This embodiment adopts 3D radar modeling technology, combined with an advanced automatic control system, to realize the intelligent management of the aggregate loading process. By deploying a 3D contour scanning lidar 4, a real-time model of the on-site loading environment is built, and the point cloud data is analyzed using AI algorithms to achieve accurate detection of the vehicle contour and precise measurement of the material volume. Through seamless docking with on-site equipment, the system can automatically control the loading equipment to achieve accurate quantitative loading. It not only significantly improves the loading speed and metering accuracy, but also greatly reduces the labor cost and safety risk. At the same time, it has high flexibility and scalability, can be customized differently according to user needs, provides strong technical support for the intelligence and automation of aggregate loading, accurately guides the actions of on-site loading equipment, and realizes automatic quantitative loading.

[0102] 2. Intelligent management: Analyze point cloud data through AI algorithms to achieve automated control and intelligent management, reducing labor costs.

[0104] 4. High efficiency and energy saving: The automated control system can adjust the action parameters of the loading equipment according to the actual situation to achieve high efficiency and energy saving.

[0105] 5. Data visualization: Record, save, and upload loading data in real time, facilitating subsequent analysis and management, and improving production efficiency.
