[0053] The accompanying drawings have illustrated specific embodiments of the present invention, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0054] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0055] In bulk material transportation scenarios, such as loading and unloading coal, ore, and grain, conveyor belts are typically used to transport materials into the truck bed.

[0056] Currently, material distribution relies on manual observation or belt conveyors at fixed speeds, making it difficult to adjust the material feeding position and stacking height in real time. With the development of automation technology, achieving precise and efficient material distribution control has become a crucial direction for optimizing loading and unloading operations in the industry.

[0057] Specifically, most systems use fixed loading conveyor belts or simple manual adjustment mechanisms, making material accumulation highly dependent on operator experience and prone to uneven loading or spillage. Some improved solutions use mechanical limits or timed control to move the belt, but lack real-time feedback capabilities and cannot dynamically adapt to the actual distribution of materials in the truck, resulting in low efficiency or waste of resources.

[0058] For example, Figure 1 A schematic diagram of material feeding provided for existing technology, such as Figure 1 As shown in the diagram, the vehicle includes: a truck bed 11, a weighbridge 12, a hopper 13, and a gate 14.

[0059] In one possible implementation, when a vehicle enters the weighbridge area, the operator controls the gate 14 of the hopper 13 to open. At this time, the operator, based on the height of the material in the truck bed 11 or by reading the weight information of the vehicle reflected by the weighbridge 12, instructs the driver to move the vehicle so that the material can be placed in other positions in the truck bed 11.

[0060] The main drawback of existing technologies lies in the lack of real-time monitoring and adaptive adjustment capabilities for material stacking height, leading to the following problems:

[0061] 1) Frequent manual intervention leads to low work efficiency and safety hazards;

[0062] 2) Uneven material distribution may cause uneven loading or overflow in the carriage.

[0063] To address the aforementioned technical problems, the inventor's technical concept is as follows: To solve this problem, the inventor combines automated control technology, which allows for real-time monitoring of the loading vehicle's weight via a truck scale, movement of the loading conveyor belt via a traveling trolley, and real-time scanning and feedback of the material pile height using a volume detection device. When the material pile reaches a preset height, the trolley is automatically controlled to move step by step, adjusting the material drop position to avoid uneven distribution of the material pile within the loading vehicle.

[0064] To make the above-mentioned objectives, features, and advantages of the embodiments of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0065] It should be noted that the terms "side", "top", "bottom", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0066] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0067] Figure 2 This is a first structural schematic diagram of the mobile belt-type automatic loading system provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the mobile belt-type automatic loading system includes: a truck scale 21, a loading belt 22, a volume detection device 23, and a traveling trolley device 24;

[0068] The traveling trolley device 24 is spaced above the truck scale 21, and the space between them is used to accommodate the loading trolley. The end of the traveling trolley device 24 facing the truck scale 21 is provided with a discharge chute 240.

[0069] The loading belt 22 is installed on the traveling trolley device, and the loading belt 22 and the material bin 42 are spaced apart; the volume detection device 23 is installed near the discharge chute 240, and is used to vertically scan the material pile in the loading car located on the truck scale 21 to detect the current height of the material pile.

[0070] In this implementation, the volume detection device 23 is installed in the discharge chute 240 of the loading belt 22 to detect the height of the material pile inside the loading vehicle on the truck scale 21 in real time.

[0071] When the volume detection device 23 detects that the current material pile height is equal to the target material pile height, the trolley device 24 drives the loading belt 22 to move according to the preset step distance.

[0072] In this implementation, the corresponding settings for the preset step distance and the target material pile height can be set based on relevant attributes such as the size of the loading vehicle and the weight of the loaded material.

[0073] For example, the target stockpile height mainly depends on the loading weight and the bulk density of the material. This ensures that after loading the predetermined weight of material, the stockpile height neither exceeds the side panels of the truck bed, preventing spillage, nor overloading the truck bed.

[0074] That is, total weight / material density = required total volume; then, the average height is calculated by back-calculating the length and width of the carriage, and an appropriate safety margin is left to obtain the target stockpile height value.

[0075] For example, setting the preset step distance essentially involves dividing the total length of the carriage by an integer, that is, dividing the carriage into N virtual small material bins along its length. The loading amount (weight or volume) at each step is 1 / N of the total loading amount.

[0076] That is, let the available effective length inside the carriage be L; let the total weight to be loaded be W; and let the preset step distance be L / N.

[0077] It should be understood that the above examples are for illustrative purposes only and are not limitations for actual implementation.

[0078] The mobile belt-type automatic loading system provided by this utility model includes: a truck scale, a loading belt, a volume detection device, and a traveling trolley device; the traveling trolley device is spaced above the truck scale, with the space between them used to accommodate the loading trucks, and a discharge chute is provided at the end of the traveling trolley device facing the truck scale; the loading belt is installed on the traveling trolley device, and the loading belt and the material bin are spaced apart; the volume detection device is installed near the discharge chute and is used to vertically scan the material pile in the loading truck located on the truck scale to detect the current material pile height; when the volume detection device detects that the current material pile height value is equal to the target material pile height value, the traveling trolley device drives the loading belt to move according to a preset step distance. This invention utilizes a truck scale to support a loading vehicle, employing a loading belt and discharge chute on a traveling trolley to achieve precise unloading. Combined with a volume detection device, it performs real-time vertical scanning and feedback of the material pile height. When the detected height reaches a preset value, the trolley is controlled to move step-by-step to adjust the material placement position. This achieves efficient, automated, and high-precision quantitative loading, effectively improving loading efficiency and material stacking uniformity. It avoids material overflow or uneven stress on the truck bed caused by excessively high local stacks, and reduces the need for manual intervention. While ensuring efficient material distribution, it optimizes space utilization, ultimately improving the stability and uniformity of the loading process.

[0079] Based on the above embodiments, Figure 3 This is a second structural schematic diagram of the mobile belt-type automatic loading system provided in an embodiment of the present invention. Figure 4 A third structural schematic diagram of the mobile belt-type automatic loading system provided in this embodiment of the utility model. Figure 4 for Figure 3 (Illustration of the main body). For example... Figure 3 As shown, the traveling trolley device 24 includes: a traveling trolley 241 and a track 242;

[0080] The track 242 is located below the traveling trolley 241 and is used to guide the running direction of the traveling trolley 241.

[0081] In this implementation, the traveling trolley 241 moves along either the front or rear direction of the track 242 to drive the loading belt 22 to run in the running direction. When a running instruction is received, the motor in the traveling trolley 241 is driven to determine the driving time, power parameters, etc. based on the preset step distance.

[0082] Optionally, the traveling trolley 241 includes: a support platform 2411 and multiple sets of wheels 2412 disposed below the support platform 2411;

[0083] The carrier platform 2411 is equipped with a coaxial encoder, which is used to detect the number of revolutions of at least one wheel 2412 among multiple sets of wheels 2412; when the distance value corresponding to the number of revolutions of at least one wheel 2412 is equal to the preset step distance, the traveling trolley 241 stops running.

[0084] In this implementation, a coaxial encoder is installed on the traveling trolley 2411. The number of revolutions of the wheels 2412 in the traveling trolley 241 can be detected by the coaxial encoder, thereby calculating the traveling distance of the traveling trolley 241, that is, the distance value corresponding to the number of revolutions.

[0085] For example, the wheels 2412 are driven by gear transmission, and the power system consists of a three-phase asynchronous motor and a hardened gear reducer. The traveling trolley 241 moves at a speed of 0.2 m per second. A coaxial encoder is installed on the transmission reducer of the power system. The number of revolutions can be detected by the coaxial encoder, thereby calculating the distance traveled by the traveling trolley 241.

[0086] Among them, the wheels 2412 are made of cast steel or forged steel, with two wheels on each side, evenly distributed, and heavy-duty roller bearings can be selected.

[0087] Based on the above embodiments, Figure 5 The fourth structural diagram of the mobile belt-type automatic loading system provided in this embodiment of the utility model is shown below. Figure 5 As shown, the mobile belt automatic loading system also includes: a weighing feeder 41 and a material bin 42;

[0088] The weighing feeder 41 is set between the loading belt 22 and the material bin 42. It is used to obtain the material in the material bin 42 and weigh it. When the current weighing value is equal to the target weighing value, the material in the weighing feeder 41 is fed onto the loading belt 22.

[0089] In this implementation, the weighing feeder 41 can be a quantitative weighing feeder, installed below the discharge gate of the material silo 42, and has a dynamic weighing function. It can track the weighing data (i.e., the current weighing value) after startup according to the set quantitative target (i.e., the target weighing value), and automatically feed material to the loading belt 22 when the target weighing value is reached.

[0090] Optionally, the mobile belt-type automatic loading system also includes limit switches installed at both ends of track 242;

[0091] When the trolley 241 moves to either end of the track 242, the limit switch is triggered, and the trolley 241 stops running.

[0092] In this implementation, limit switches are installed at both ends of the track 242. When the traveling trolley 241 travels to the limit position at either end of the track, the limit switches are triggered and the trolley stops automatically.

[0093] Optionally, the volume detection device 23 can be configured as a millimeter-wave radar, lidar, etc., and installed next to the discharge chute 240 by a rigid connection.

[0094] Millimeter-wave radar is used to vertically scan the material pile inside the loading vehicle located on the truck scale 21 to detect the current height of the material pile.

[0095] In this implementation, the millimeter-wave radar can be an industrial-grade millimeter-wave radar, used as a device for detecting the height of the material pile inside the carriage. The range can be selected according to the height of the carriage. It can be installed on the rear side of the discharge chute 240 to scan vertically downwards and detect the slope height of the currently loaded material pile, i.e., the current material pile height.

[0096] Optionally, the mobile belt-type automated loading system also includes: controller 43;

[0097] The truck scale 21 is used to carry the loading truck and weigh it; when the current weight information of the loading truck is equal to the target weight information, the controller 43 prompts the loading truck to leave the truck scale 21.

[0098] In this implementation, the truck scale 21 completely lifts the vehicle and weighs it. Based on the material delivery process, the weight information measured by the truck scale 21 changes continuously and is transmitted to the controller 43 in real time.

[0099] That is, when the model of the loading vehicle is known, the size information and load information of the truck body are known, the controller 43 can also adjust the preset step distance of the traveling trolley 241 in real time based on the weight information measured by the truck scale 21.

[0100] In one possible implementation, the controller 43 can be integrated into the volume detection device 23 or it can be a separate device used to send control commands to other devices when the current material pile height value detected by the volume detection device 23 is equal to the target material pile height value.

[0101] Among them, the controller 43 can be an industrial-grade programmable logic controller (PLC) to realize the automated control of the feeding, weighing, moving and loading process.

[0102] Optionally, the mobile belt-type automatic loading system also includes: a through-beam light curtain 44;

[0103] The through-beam light curtain 44 is installed on both sides of the truck scale 21 to detect the current position of the loading truck relative to the truck scale 21; when the current position of the loading truck is at the target position, the controller 43 prompts the loading truck to park in compliance with regulations.

[0104] In this implementation, a through-beam light curtain 44 is used to detect the parking alignment of the vehicle relative to the unloading port. It is installed on both sides of the truck scale 21. When the front and rear sides of the truck body approach the unloading port, the distance between the front and rear positions of the truck body and the unloading port can be detected, that is, the current position is mapped.

[0105] Furthermore, when the current position is at the target position (e.g., the initial loading position), the controller 43 controls the traveling trolley 241 to stop, so that the traveling trolley 241 stops and then the unloading operation is realized.

[0106] Optionally, the mobile belt-type automatic loading system also includes: a vehicle authentication unit 45, which includes at least one of the following: a barcode scanner, a card reader, or a barcode scanner and card reader.

[0107] The vehicle authentication unit 45 is set at the first position corresponding to the cab at the initial stop position of the vehicle, and is used to obtain the current model of the loading vehicle; the controller 43 is used to determine the control parameters according to the current model. The control parameters include at least one of the following: preset step distance, target material pile height value, and target weight information (the control parameters may be different for different vehicle models).

[0108] In this implementation, a barcode scanner, card reader, or barcode scanner / card reader combo machine is used to verify vehicle identity. It is installed in the driver's cab at the initial parking position and supports integrated circuit (IC) card swiping and / or QR code scanning.

[0109] Optionally, the mobile belt-type automated loading system may also include: interactive equipment;

[0110] An interactive device for setting control parameters of controller 43.

[0111] In this implementation, the interactive device can be a touch screen display, which serves as a human-computer interaction interface. The interface is simple and intuitive, and is used to set control parameters such as target weight, step size, and speed.

[0112] In one possible implementation, the interactive device may be a controller 43 with an operating interface or operating buttons.

[0113] In addition, the mobile belt-type automatic loading system can also be equipped with safety features such as emergency stop buttons, overload protection, and limit protection to ensure the safe operation of the system.

[0114] It should be understood that the dotted lines in the attached diagram represent the movement of the trolley device 24 carrying the relevant units before or after the movement.

[0115] This utility model provides a mobile belt-type automatic loading system, which further includes: a weighing feeder, a material bin, a millimeter-wave radar, a controller, a through-beam light curtain, a vehicle authentication unit, and interactive equipment. The weighing feeder is located between the loading belt and the material bin, used to acquire and weigh the material in the bin. When the current weighing value equals the target weighing value, the material in the weighing feeder is fed onto the loading belt. The millimeter-wave radar is used to vertically scan the material pile inside the loading vehicle located on the truck scale to detect the current height of the material pile. The truck scale is used to support the loading vehicle and weigh it. When the loading vehicle... When the current weight information equals the target weight information, the controller prompts the loading vehicle to leave the truck scale. Through-beam light curtains are installed on both sides of the truck scale to detect the current position of the loading vehicle relative to the scale. When the loading vehicle's current position is at the target position, the controller prompts the vehicle to park compliantly. The vehicle authentication unit is set at the first position corresponding to the cab at the vehicle's initial stop position to obtain the current model of the loading vehicle. The controller determines control parameters based on the current model, including at least one of the following: preset step distance, target material pile height, and target weight information. An interactive device is used to set the controller's control parameters. This mobile belt-type automatic loading system achieves precise weighing and material pile height monitoring through a weighing feeder, millimeter-wave radar, truck scale, and through-beam light curtains. Combined with the vehicle authentication unit and controller, it automatically matches vehicle model parameters, optimizes the loading process, and reduces manual intervention. Simultaneously, the interactive device sets control parameters to ensure uniform material loading, avoiding uneven loading or overflow, thereby improving loading efficiency, safety, and automation, and achieving efficient and accurate fully automated unmanned loading operations.

[0116] Based on the above embodiments, an operational scenario flow for a mobile belt-type automated loading system can also be provided, namely:

[0117] 1) After the empty vehicle arrives, it drives onto the weighbridge 21 and stops at the card-swiping and barcode-scanning integrated box; the driver verifies the vehicle identification by swiping a card or scanning a barcode to obtain vehicle information.

[0118] 2) The vehicle information includes the target load and the length, width and height of the cargo box. After the information is verified by swiping a card or scanning a code, the vehicle is weighed and the tare weight is recorded.

[0119] The target load information is input into the quantitative weighing feeder 41 as the quantitative target of this vehicle; the target gross weight is calculated based on the tare weight and the target load, and is used as the weighing target of the vehicle's truck scale 21; the target material pile height (i.e., height threshold) and the step distance of the traveling trolley 241 are calculated based on the target load and the length, width and height of the truck body.

[0120] 3) The position information of the front side of the car is detected by the through-beam light curtain 44, and the traveling trolley 241 is started so that the discharge chute 240 is aligned with the set area of ​​the front side of the car. At this time, the traveling trolley 241 stops.

[0122] 5) During material unloading, the height of the material pile inside the vehicle is detected by millimeter-wave radar. When the material pile height reaches the target height, the traveling trolley 241 is controlled to move a calculated step distance towards the rear of the vehicle and then stop. Afterwards, the height of the material pile is monitored by millimeter-wave radar, and the step movement logic is repeated.

[0123] 6) The step-size logic is executed in a loop until the cumulative weight of the weighing feeder 41 reaches the target load, at which point the weighing feeder 41 is stopped and the gate is closed.

[0124] 7) When the weight on the truck scale 21 reaches the target gross weight, stop the loading conveyor belt; the loading of this truck is completed, and the gross weight is recorded; after the truck is loaded, the driver can drive away.
