Description

Technical Field

[0001] This utility model relates to the field of material loading equipment, and in particular to an intelligent material loading equipment. Background Technology

[0002] When loading and transferring bulk materials such as grain, it is necessary to accurately load the materials into the truck bed to avoid spillage.

[0003] In existing technologies, the discharge port of a silo containing materials is generally a single-hole structure, resulting in low discharge efficiency. During loading, to prevent material from accumulating in one spot within the truck bed, the vehicle needs to be moved back and forth repeatedly around the discharge port at the bottom of the silo, discharging material in multiple stages to ensure complete and uniform filling along the length of the truck bed. This process requires the driver to move the vehicle in a timely manner; if the driver fails to move the vehicle promptly or moves it beyond the designated area, material overflow can easily occur, leading to underloading and material waste. Furthermore, to coordinate with vehicle movement, the silo's discharge door also needs to be opened and closed repeatedly, making the operation cumbersome and resulting in low loading efficiency.

[0004] The current common practice is to assign a dedicated loading supervisor on-site. This supervisor guides the truck driver to move the truck forward or backward around the discharge port at the bottom of the silo, loading material in multiple stages. The supervisor controls the opening and closing of the discharge gate at the silo discharge port based on the current position of the truck and the actual material load in the truck bed. This process is repeated until the truck bed is full. Even so, if the coordination between the two is not good, there is still a possibility of material spillage or underloading. The overall operation is quite cumbersome and requires a high level of skill from both the truck driver and the supervisor.

[0005] In summary, traditional loading methods have the following problems and shortcomings:

[0006] It is labor-intensive, requiring the full participation of on-site loading supervisors and material transport vehicle drivers. It demands high levels of experience and technical skills from personnel, and the working environment for workers is poor, with high labor intensity and poor safety.

[0007] When loading, the material transport vehicle must be moved back and forth multiple times to be fully loaded, which is complicated, time-consuming, and inefficient. Each driver has different driving habits, resulting in significant differences in the forward and backward movement of the vehicle and varying loading capacities. This leads to secondary weighing and loading of the vehicle, resulting in low loading efficiency and the inability to establish a standardized operating procedure. Utility Model Content

[0008] To address the aforementioned problems in the prior art, this utility model provides an intelligent material loading device to solve the issues existing in the background technology.

[0009] The technical solution adopted by this utility model to solve its technical problem is as follows: an intelligent material loading equipment, including a frame; a material conveyor is installed on the frame, and a feed pipe is installed on the shell of the material conveyor, with both ends of the feed pipe connected to a hopper and the inner cavity of the material conveyor, respectively; multiple discharge ports are provided at the bottom of the shell of the material conveyor, and telescopic chutes are installed below the discharge ports, with openings at the top and bottom of the telescopic chutes; the inner cavity of the material conveyor, the discharge ports, and the telescopic chutes are connected in sequence; an electric discharge hopper door for controlling the opening state of the discharge ports is installed at the discharge ports; a lifting bracket is connected to the bottom of all the telescopic chutes, and the lifting bracket is connected to the frame through a lifting assembly; the front end of the bottom of the frame is the vehicle outlet, and the rear end of the bottom of the frame is the vehicle inlet.

[0010] Furthermore, the material conveyor can be a screw conveyor or a scraper conveyor. The appropriate type of conveyor can be selected according to the type of material. For example, a screw conveyor can be used for powdery materials such as cement, coal powder, lime powder, and fly ash, while a scraper conveyor can be used for small granular materials such as grains and plastic granules.

[0011] Furthermore, the discharge port has a funnel-shaped structure, which can promote material flow, prevent blockage, concentrate material discharge, and facilitate the installation of an electric discharge hopper door.

[0012] Furthermore, the electric discharge hopper door is preferably an electric gate valve, and the opening and closing state of the gate valve is realized by circuit control.

[0013] Furthermore, the lifting assembly is preferably a wire rope pulley lifting device, which is powered by a matching motor. The combination of wire rope and pulley block is used to raise and lower the lifting support, thereby controlling the height of the bottom opening of the telescopic chute. This allows the bottom of the telescopic chute to be as close as possible to the loading compartment, effectively reducing the drop height of the material. The wire rope pulley lifting device is equipped with a tension sensor and a limit switch sensor. When the lifting support touches the upper edge of the compartment baffle, the lifting support receives an upward supporting force. The tension sensor detects a decrease in the tension of the wire rope, triggering the limit switch sensor to stop the wire rope pulley lifting device from descending.

[0014] Furthermore, the lifting support is preferably a square frame, with the frame hoisted and connected to the machine frame around the square frame by a lifting assembly. The square frame has an opening corresponding to the bottom opening of each telescopic chute, and the material falling from the bottom opening of the telescopic chute can enter the loading compartment through the internal opening of the telescopic chute.

[0015] Furthermore, the intelligent material loading equipment also includes a control system, which consists of an interconnected vehicle location automatic guidance subsystem, a vehicle type recognition subsystem, an intelligent loading subsystem, and a local manual control subsystem.

[0016] The automatic vehicle location guidance subsystem is used to detect vehicle location information and guide the vehicle to the loading area.

[0017] The vehicle identification subsystem is used to confirm vehicle information, detect material level data in the compartment, and adjust the height of the lifting bracket.

[0018] The intelligent loading subsystem is used to control the opening and closing of the corresponding electric unloading bin door to accurately unload materials into the truck.

[0019] The local manual control subsystem is used to provide emergency shutdown and manual operation capabilities in case of emergencies or automatic mode failures, ensuring safety and allowing operators to directly control each stage to complete the loading process in an orderly manner.

[0020] Furthermore, the automatic vehicle positioning guidance subsystem includes guidance control software, a PLC controller, parking space radar sensor components, a text display screen, and traffic lights. The text display screen and one traffic light are located at the front of the rack, corresponding to the direction of the vehicle's front end; another traffic light is located at the rear of the rack, corresponding to the direction of the vehicle's rear end. The text display screen and traffic lights are used to display vehicle guidance information. The parking space radar sensor components are arranged in two sets, each set including two ultrasonic radar sensors. The two ultrasonic radar sensors in the first set are installed above and to the side of the vehicle exit at the front of the rack, and the two ultrasonic radar sensors in the second set are installed above and to the side of the vehicle entrance at the rear of the rack. The second set of parking space radar sensors at the vehicle entrance at the rear of the rack is used to detect whether a vehicle is entering, and the first set of parking space radar sensors at the vehicle exit at the front of the rack is used to detect the position of the front panel of the vehicle compartment.

[0021] Furthermore, the vehicle model recognition subsystem includes vehicle model recognition software, a PLC controller, a material level radar sensor, and a lifting component distance sensor. The material level radar sensor is installed on the side of each discharge port, and the lifting component distance sensor is installed on the frame above the lifting bracket. The material level radar sensor is used to detect the material level data in the carriage below it. The lifting component distance sensor is used to detect the dynamic distance between the lifting bracket and the upper edge of the side baffle of the carriage in real time.

[0022] Furthermore, the intelligent loading subsystem includes loading software, a PLC controller, a power control cabinet, an electric unloading hopper door switch sensor, unloading port switch status indicator lights, and an external data interface. The electric unloading hopper door switch sensor is installed at the electric unloading hopper door, and the unloading port switch status indicator lights are installed above each unloading port. The unloading port switch status indicator lights are red, yellow, and green LED lights. A red light indicates that the electric unloading hopper door is closed, a green light indicates that the electric unloading hopper door is open, and a yellow light indicates that there is a vehicle below the corresponding unloading port, entering the unloading standby state. The external data interface can interact with the truck scale, belt scale, and the upper-level production management system.

[0023] Furthermore, the local manual control subsystem includes a manual control box, a touch screen, and a remote controller. The manual control box is mounted on the frame and contains a manual / automatic mode switch button, a manual control button, an emergency stop button, a touch screen, and a remote wireless control module. In case of an emergency requiring the material conveyor to be shut down, pressing the emergency stop button or the emergency stop function key on the touch screen will shut down the material conveyor. Switching the manual / automatic mode switch button to manual control mode allows for remote operation via the on-site manual control button or a portable wireless controller / remote controller. Operators can direct the transport vehicle's operation and manually control the material conveyor and the operating status of each electric unloading hopper door and lifting component to complete the entire loading process. The touch screen displays the current loading status, vehicle information, material information, loading weight, material conveyor, each unloading hopper, and the operating status of the lifting component through intuitive graphics and animations. If any automatic operation subsystem malfunctions, vehicle information can be set on-site to ensure the smooth completion of the entire loading process.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0044] Example 1, referring to Figure 1-9 This embodiment provides an intelligent material loading device, including a frame 1; a material conveyor 2 is installed on the frame 1, and a feed pipe 3 is installed on the shell of the material conveyor 2. The two ends of the feed pipe 3 are respectively connected to a hopper containing materials and the inner cavity of the material conveyor 2; the bottom of the shell of the material conveyor 2 is provided with multiple discharge ports 4, and the lower part of the discharge ports 4 is connected to a telescopic chute 5 through a flange. The top and bottom of the telescopic chute 5 are provided with openings; the inner cavity of the material conveyor 2, the discharge ports 4, and the telescopic chute 5 are connected in sequence; an electric discharge hopper door 6 is installed at the discharge port 4 to control the opening state of the discharge port; the bottom of all the telescopic chute 5 is connected to a lifting bracket 7, and the lifting bracket 7 is connected to the frame 1 through a lifting assembly 8; the front end of the bottom of the frame 1 is a vehicle outlet, and the rear end of the bottom of the frame 1 is a vehicle inlet. The space under the lifting bracket 7 can accommodate material transport vehicles, and the material transport vehicles can be parked at the loading position under the lifting bracket 7 for loading.

[0045] In this embodiment, a suitable type of material conveyor 2 can be selected according to the material type. For example, a screw conveyor can be selected for powdery materials such as cement, coal powder, lime powder, and fly ash, while a scraper conveyor can be selected for small granular materials such as grains and plastic granules.

[0046] In this embodiment, in order to promote material flow, prevent blockage, concentrate material discharge, and facilitate the installation of the electric discharge hopper door 6, the discharge port 4 is configured as a funnel-shaped structure that is wider at the top and narrower at the bottom.

[0047] In this embodiment, the electric discharge hopper door 6 is preferably an electric gate valve, and the opening and closing state of the electric discharge hopper door 6 is controlled by the circuit.

[0048] In this embodiment, the lifting support 7 is preferably a square frame. The frame is hoisted and connected to the machine frame by the lifting components 8. The inside of the square frame is provided with an opening corresponding to the bottom opening of each telescopic chute 5. The material falling from the bottom opening of the telescopic chute 5 can enter the loading compartment through the opening inside the square frame.

[0049] In this embodiment, the lifting assembly 8 is preferably a wire rope pulley lifting device. Power is provided by a matching motor, and the combination of wire rope and pulleys enables the lifting support 7 to rise and fall, thereby controlling the height of the bottom opening of the telescopic chute 5. This allows the bottom of the telescopic chute 6 to be as close as possible to the loading compartment, effectively reducing the material's fall height. The wire rope pulley lifting device is equipped with a tension sensor and a limit switch sensor. When the lifting support 7 touches the upper edge of the compartment baffle, the lifting support 7 receives an upward supporting force. The tension sensor detects a decrease in the wire rope tension, triggering the limit switch sensor to stop the wire rope pulley lifting device from descending.

[0050] In this embodiment, since the installation of the equipment is easily affected by the limitations of the equipment layout of the installation site, the feed pipe 3 can be installed at one end, the middle, or near the middle of the housing of the material conveyor 2. If the feed pipe 3 is installed at one end of the housing of the material conveyor 2, when the electric discharge door corresponding to the first discharge port in the direction of the vehicle head is opened, the material conveyor 2 is started to feed material in the direction of the vehicle head, and the feed pipe 3 is linked to start discharging material, so that the material is discharged sequentially from the discharge port. If the feed pipe 3 is installed in the middle or near the middle of the housing of the material conveyor 2, the material is discharged and discharged sequentially on one side of the feed pipe 3 first. After the material is discharged and loaded on this side, the spiral blades or scrapers in the material conveyor 2 are controlled to reverse the operation, and then the material is discharged and discharged sequentially on the other side of the feed pipe 3, so as to realize the unloading and loading of the entire vehicle.

[0051] In this embodiment, the intelligent material loading equipment also includes a control system, which consists of an interconnected vehicle position automatic guidance subsystem, a vehicle type recognition subsystem, an intelligent loading subsystem, and a local manual control subsystem. The vehicle position automatic guidance subsystem is used to detect vehicle position information and guide the vehicle to the loading area below the frame 1. The vehicle type recognition subsystem is used to confirm vehicle information, detect material level data in the truck bed, and adjust the height of the lifting bracket 7. The intelligent loading subsystem is used to control the opening and closing of the corresponding electric unloading bin door 6 to accurately unload materials into the truck bed. The local manual control subsystem is used to provide emergency stop and manual operation capabilities in case of emergencies or automatic mode failures, ensuring safety and allowing the operator to directly control each step to complete the loading process in an orderly manner.

[0052] The automatic vehicle positioning guidance subsystem includes guidance control software, a PLC controller, a parking space radar sensor assembly 11, a text display screen 9, and traffic lights 10. The text display screen 9 and one traffic light 10 are located at the front of the frame 1, corresponding to the direction of the vehicle's front end; the other traffic light 10 is located at the rear of the frame 1, corresponding to the direction of the vehicle's rear end. The text display screen 9 is preferably an LED screen. The text display screen 9 and traffic lights 10 are used to display vehicle guidance information. The parking space radar sensor assembly 11 has two sets, each set including two ultrasonic radar sensors. The two ultrasonic radar sensors in the first set are installed above and to the side of the vehicle exit at the front of the frame to detect the position of the front panel of the vehicle compartment. The two ultrasonic radar sensors in the second set are installed above and to the side of the vehicle entrance at the rear of the frame to detect whether a vehicle has entered the area below the frame.

[0053] The vehicle model recognition subsystem includes vehicle model recognition software, a PLC controller, a material level radar sensor 12, and a lifting assembly distance sensor 13. The material level radar sensor 12 is installed on the side of each discharge port 4, and the lifting assembly distance sensor 13 is installed on the frame 1 above the lifting bracket 7. The material level radar sensor 12 is used to detect the material level data in the truck bed below it. The lifting assembly distance sensor 13 is used to detect the dynamic distance between the lifting bracket 7 and the upper edge of the side baffle of the truck bed in real time. When the loading vehicle stops at the designated loading position, the on-site PLC controller controls the lifting bracket 7 to descend to the upper edge of the truck bed via the lifting assembly 8 and stops descending. The on-site PLC controller determines the height of the truck bed based on the descent height data of the lifting bracket 7 detected by the lifting assembly distance sensor 13, and thus determines the loading height of the material.

[0054] The intelligent loading subsystem includes loading software, a PLC controller, a power control cabinet, an electric unloading hopper door switch sensor, unloading port switch status indicator lights, and an external data interface. The electric unloading hopper door switch sensor is installed at the electric unloading hopper door, and the unloading port switch status indicator lights are installed above each unloading port. The unloading port switch status indicator lights are red, yellow, and green LED lights. A red light indicates that the electric unloading hopper door is closed, a green light indicates that the electric unloading hopper door is open, and a yellow light indicates that there is a vehicle below the corresponding unloading port, entering the unloading standby state. The external data interface can interact with the truck scale, belt scale, and the upper-level production management system.

[0055] The local manual control subsystem includes a manual control box, a touch screen, and a remote controller. The manual control box is mounted on the frame 1 and contains a manual / automatic mode switch button, a manual control button, an emergency stop button, a touch screen, and a remote wireless control module. In case of an emergency requiring the material conveyor to be shut down, pressing the emergency stop button or the emergency stop function key on the touch screen will shut down the material conveyor. Switching the manual / automatic mode switch button to manual control mode allows for remote operation via the on-site manual control button or a portable wireless controller / remote controller. Operators can direct the transport vehicle's operation and manually control the material conveyor, each electric unloading hopper door, and the lifting assembly's operating status to complete the entire loading process. The touch screen displays the current loading status, vehicle information, material information, loading weight, material conveyor, each unloading hopper, and the lifting assembly's operating status through intuitive graphics and animations. If any automatic operation subsystem malfunctions, vehicle information can be reset on-site to ensure the smooth completion of the entire loading process.

[0056] Example 2: This example provides a loading method for the intelligent material loading equipment, including the following steps:

[0057] a) In automatic loading mode, the vehicle position automatic guidance subsystem, vehicle type recognition subsystem, and intelligent loading subsystem are started simultaneously; the PLC controller collects the detection data from the parking space radar sensor, material level radar sensor, lifting component distance sensor, and on-site truck scale or belt scale in real time; the PLC controller collects the above signals in real time; through the built-in intelligent control software program, it automatically calculates the loading height, i.e. the height of the "material full zone", the loading length (vehicle length), and automatically determines the current vehicle loading status, including the vehicle "in place" status and whether there is a "vehicle" under each discharge port.

[0058] b) When the loading vehicle arrives at the loading area, the PLC controller determines that the entrance lane gate is in a "vehicle present" state, and the traffic lights in the front and rear directions of the vehicle turn on "yellow light" at the same time. At this time, the text display screen on the front of the vehicle displays "Please slowly move forward to move forward", prompting the vehicle to continue moving forward.

[0059] c) When the parking radar sensor at the front of the frame detects the front panel of the transfer vehicle's cargo compartment, the PLC controller determines that the loading vehicle is "in place," and the traffic lights simultaneously change from "yellow" to "red." The integrated text display shows "Please stop and wait for loading." For all discharge ports with cargo compartments below them, the discharge port switch status indicator lights up in "yellow," while those without cargo compartments below them remain in "red." The vehicle stops and waits for the material to be loaded. At the same time, when the on-site PLC control cabinet controls the lifting bracket to descend to the upper edge of the cargo compartment, the limit switch sensor is triggered, and the lifting bracket stops descending. The on-site PLC control determines the height of the vehicle's cargo compartment based on the descent height data of the lifting bracket detected by the distance measuring sensor of the lifting component, and thus determines the loading height of the material. The electric discharge hopper door corresponding to the first discharge port in the direction of the vehicle head opens (the discharge port switch status indicator light changes from "red" to "green"), and the material conveyor starts rotating and feeding material in the direction of the vehicle head. The upper feed pipe starts discharging material, and the loading weight data of the material loaded into the cargo compartment is received in real time through the data interface of the external truck scale or belt scale.

[0060] d) The PLC controller controls the continuous loading of materials into the truck body according to the "material full zone" height requirements of different loading vehicles. When the material level radar sensor of the first discharge port in the front direction of the truck detects that the current material level is at the "material full zone" height, the electric discharge door corresponding to the adjacent second discharge port opens (the discharge port switch status indicator light changes from "red light" to "green light"), and materials are discharged sequentially from the front to the rear of the truck. This cycle continues until the corresponding discharge port at the rear of the truck is reached.

[0061] e) If a spiral trough conveyor is used at the loading site, and a receiving port is set in the middle of the cover plate above the horizontal spiral conveyor hopper to connect to the discharge port of the upstream material conveying equipment, during the loading process, when the front of the truck bed sequentially discharges material from the first discharge port to the discharge port below the discharge port of the feed pipe connected to the upstream material conveying equipment, the control system controls the spiral blade conveying device of the spiral trough conveyor to change direction from the front direction to the rear direction of the truck. At the same time, the electric discharge hopper door at the upper discharge port at the rear end of the truck opens, and material is sequentially discharged from the discharge port at the rear end of the truck to the discharge port below the discharge port of the feed pipe. If the spiral trough multi-port intelligent loading machine has the receiving port of the horizontal spiral conveyor hopper set at one end (rear direction), this process is skipped.

[0062] f) Throughout the loading process, the loading metering and control system are linked. When the loading weight reaches the system's set value, regardless of which discharge port the material is discharged to, the intelligent loading control system will prioritize stopping the loading procedure and ending the discharge. If the control system sets all discharge ports and the loading height of the bulk materials loaded into the truck reaches the set material level, but the loading weight still does not reach the system's set value, the control system will also stop the loading procedure and push vehicle loading information to the on-site management personnel. The on-site management personnel will then decide whether to adjust the loading material level setting value and continue loading (repeating the loading steps of ce) until the set loading weight is reached; or stop loading and end the discharge.

[0063] g) After the material discharge is completed, all electric unloading hopper doors are closed, the unloading port switch status indicator light changes from "green" to "red"; the telescopic chute retracts upward to the standby position; the traffic signal light at the vehicle exit position turns from "red" to "green" and illuminates, the integrated text display screen shows the loading weight information and the prompt "Loading complete, please leave", guiding the vehicle driver to drive out of the loading area;

[0064] h) When the vehicle leaves the loading area, the yellow light at the unloading port turns off; the barrier gate lowers, and the traffic light at the exit position turns from green to red; the integrated text display screen turns off; and the traffic light at the entry lane turns from red to green. The loading equipment enters loading standby mode, waiting for the next vehicle to arrive, thus completing the entire loading process.

[0065] Of course, the above description is not limited to the examples above.
