Description

Technical Field

[0001] The present invention relates to the field of sand and gravel loading devices, and in particular to a fully automatic intelligent sand and gravel loading and distributing device. Background Art

[0002] Sand and gravel are common building blocks used in construction projects and typically require specialized equipment for processing, transportation, and loading. Currently, commonly used sand and gravel processing equipment includes mobile loaders, fixed conveyors, and mobile unloaders. Mobile loaders are used to dig sand and gravel from the raw material yard and load it into a bucket; fixed conveyors are used to transport sand and gravel from the bucket to a designated location; and mobile unloaders are used to unload sand and gravel from the conveyor into transport vehicles. The operating principles and structures of these devices are relatively simple, but the following problems exist in actual operation:

[0003] Inaccurate manual operation. Because these devices require manual operation and control, they are susceptible to factors such as operator skill level, experience, and attention span, leading to operational inaccuracies. For example, during conveying and unloading, the belt speed may be too fast or too slow; during unloading, the hopper opening and closing time may be too long or too short. These operational inaccuracies can affect the quality and quantity of sand and gravel, resulting in resource waste and environmental pollution.

[0004] Manual operation is unintelligent. Because these devices lack intelligent control systems, they are unable to automatically adjust their operating parameters and status based on the characteristics and requirements of the sand and gravel. For example, they cannot automatically select the appropriate conveying process based on the sand and gravel type; during conveying and unloading, they cannot automatically calculate and adjust the belt speed and hopper opening and closing times based on the weight of the sand and gravel; during unloading, they cannot automatically determine and provide feedback on whether the unloading meets the standards based on the transport vehicle capacity, target weight, error range, and other requirements, and automatically generate and print loading documents. These unintelligent operations affect the quality and efficiency of sand and gravel production, leading to customer dissatisfaction and complaints.

[0005] Manual operation is unsafe. Because these devices involve the movement of heavy machinery and the control of high-voltage electrical equipment, they present certain safety risks. For example, during conveying and unloading, belts may break or slip; during unloading, the bucket may become stuck or experience electrical leakage. These unsafe operations can endanger the safety of personnel and equipment, resulting in casualties and damage to the equipment. Summary of the Invention

[0031] Control system includes central controller, license plate identifier, scanner, audible and visual alarm and video monitor, central controller is connected with distributing mechanism 5, feeding belt conveyor 4, walking device 3, license plate identifier, scanner, audible and visual alarm and video monitor communication.

[0032] Through the one-to-one correspondence of multiple raw material yards 1, feeding belt conveyor 4, walking device 3, distributing mechanism 5 and the cooperation of transport track 2, the individual weighing and loading of each sandstone material type can be realized, and the loading ratio and accuracy of each sandstone material type are ensured. At the same time, synchronous loading of multiple vehicles is also realized, thereby improving the efficiency of loading and distributing.

[0033] Transport track 2 includes transverse track 201, longitudinal track 202, and the two are interconnected to form a rectangular track array, wherein the number of transverse track 201 on each side is not less than two, and the longitudinal track 202 is correspondingly connected with feeding belt conveyor 4 and distributing mechanism 5 at both ends.

[0034] Transport track 2 is used to limit and plan the moving track of walking device 3 on one hand, and share a part of the weight of sandstone material, thereby reducing the moving load of walking device 3 and improving the service life.

[0035] The number of transverse track 201 on each side is not less than two, which avoids the problem of blockage when multiple loading and distributing devices run simultaneously, and the longitudinal track 202 is correspondingly connected with feeding belt conveyor 4 and distributing mechanism 5 at both ends, so that the walking device can directly move in a straight line from feeding belt conveyor 4 to distributing mechanism 5 after loading, thereby improving the overall operation efficiency.

[0036] Walking device 3 includes moving seat 307, which has independent moving function, and rotating seat 306 is fixedly connected to the upper surface of moving seat 307, and weighing device is fixedly connected to the output end of rotating seat 306, feeding hopper 301 is arranged above the weighing device, and feeding hopper 301 is used to load sandstone material output by feeding belt conveyor 4.

[0037] The moving seat 307 is a moving component of the traveling device 3 and is mainly used to drive the traveling device 3 to move.

[0038] The outer wall of the feeding hopper 301 is fixedly connected to a fixing frame 302 , and two opposite side walls of the fixing frame 302 are rotatably connected to limiting rollers 303 , which are sleeved in the track groove of the transport track 2 .

[0039] By sleeve-mounting the limiting roller 303 in the track groove of the transport track 2 , the transport track 2 limits the moving path of the walking device 3 to avoid deviation.

[0040] The weighing device includes a weighing bin 305, the outer bottom wall of the weighing bin 305 is fixedly connected to the output end of the rotating seat 306, the inner bottom wall of the weighing bin 305 is fixedly connected to an electronic scale 310, the upper surface of the weighing pan of the electronic scale 310 is fixedly connected to the bottom end of the hydraulic cylinder 309, the output end of the hydraulic cylinder 309 is fixedly connected to a limit seat 308, the side wall of the limit seat 308 is slidably connected to the inner wall of the weighing bin 305, and the four corners of the top of the limit seat 308 are respectively fixedly connected to support rods 304, the top of the support rod 304 passes through the upper wall of the weighing bin 305, and is fixedly connected to the lower wall of the fixed frame 302.

[0041] The electronic scale 310 is used to weigh the sand and gravel in the feed hopper 301. During weighing, the feed hopper 301 must be pre-raised by the hydraulic cylinder 309 to prevent the load-bearing capacity of the transport track 2 from affecting the weight. Simultaneously, when the travel device 3 needs to turn, the hydraulic cylinder 309 first contracts, causing the movable seat 307 to leave the bottom surface. This in turn causes the rotating seat 306 to rotate, causing the movable seat 307 to turn. The hydraulic cylinder 309 then extends, separating the limiting roller 303 from the transport track 2. Similarly, the rotating seat 306 rotates, causing the limiting roller 303 to turn.

[0042] The material distributing mechanism 5 includes a material distributing belt conveyor, the lower wall of which is fixedly connected to a bracket 502 , and the bottom end of the bracket 502 is fixedly connected to the moving end of the electric slide rail 503 .

[0043] The bracket 502 is driven to move by the electric slide rail 503 to enable the material conveyor belt to be inserted into or pulled out from under the feeding hopper 301 to avoid interference with the movement of the walking device 3.

[0044] The fabric belt conveyor includes a first belt conveyor 501, the lower wall of the first belt conveyor 501 is fixedly connected to the top of the bracket 502, an electric slide 504 is arranged below the first belt conveyor 501, the outer wall of the electric slide 504 passes through and is fixedly connected to the middle of the bracket 502, and the sliding end of the electric slide 504 is fixedly connected to the second belt conveyor 505.

[0045] The sand and gravel flowing out of the discharge port of the feeding hopper 301 is transported by the first belt conveyor 501 to the second belt conveyor 505, and then transported to the rear bucket of the vehicle. The position of the second belt conveyor 505 is controlled and adjusted by the electric slide 504. In conjunction with the video monitor and the central controller, the material distribution position is adjusted according to the current sand and gravel loading situation of the vehicle, thereby making the material distribution more uniform, compact and reasonable.

[0046] The outer wall of the electric slide 504 is also provided with a vehicle detection radar and an infrared sensor for detecting the position and size of the vehicle to be loaded and transmitting the signal to the central controller.

[0047] The audio and visual warning system includes an LED screen, a sound bar, and traffic lights, providing voice and graphic instructions to the driver. Meanwhile, the video surveillance system, which includes multiple cameras and display screens, monitors the loading site in real time and transmits images to the central controller and control room.

[0048] By using license plate recognition devices, scanners, sound and light alarms and video monitors, intelligent command and supervision of the loading process can be achieved. By identifying the order information and license plate number provided by the driver, the order validity and customer identity can be verified. Through voice and graphic instructions, the driver is guided to park the vehicle in the correct position. The inspection radar and infrared sensor can be used to detect the position and size of the vehicle to be loaded to prevent misloading or missing. The camera and display screen can be used to monitor the situation at the loading site in real time to prevent theft or leakage.

[0049] The central controller uses a PLC controller with data storage, analysis and processing functions.

[0050] Order information includes order number, customer name, license plate number, type and quantity of sand and gravel, etc.; vehicle information includes vehicle model, load capacity, compartment size, etc.; sand and gravel information includes type, density, stacking coefficient, etc.

[0051] By using a PLC controller as the central controller, the loading plan can be automatically generated and dynamically adjusted. According to order information, vehicle information, sand and gravel information and loading parameters, the optimal material distribution process can be automatically calculated, and the loading process can be adjusted in time according to real-time feedback signals, thereby improving operational flexibility and intelligence.

[0052] The workflow is as follows:

[0053] The driver arrives at the loading site and provides the order information and license plate number to the license plate recognition device, which transmits the signal to the central controller;

[0054] The central controller queries the database according to the order information and the license plate number, obtains corresponding vehicle information, sandstone material information and loading parameters, and automatically generates a loading scheme according to the information;

[0055] The central controller sends voice and graphical instructions to the driver through the audible and visual alarm, guides the driver to park the vehicle at the correct position, and verifies the order validity and customer identity through the scanner;

[0056] The central controller automatically controls the walking device 3 to move to the corresponding raw material yard 1 according to the loading scheme, controls the feeding belt conveyor 4 to send the corresponding sandstone material into the feeding hopper 301, and then controls the walking device 3 to move to the loading position. According to the loading scheme, the central controller automatically controls the material distribution mechanism 5 to drop the sandstone material into the vehicle hopper of the vehicle to be loaded, and controls the electric slide 504 according to the video monitoring information to drive the second belt conveyor 505 to uniformly distribute the sandstone material in the rear hopper.

[0057] The central controller monitors the loading weight of each sandstone material in real time, and compares it with the order information. When the predetermined quantity is reached, the central controller automatically stops loading.

[0058] The central controller dynamically adjusts the loading process according to the real-time feedback signal, such as adjusting the running speed of the walking device 3, the feeding belt conveyor 4 and the material distribution mechanism 5.

[0059] The central controller monitors the loading site in real time through the video monitor, and transmits the image to the central control room to prevent the occurrence of stealing and leakage.

[0060] When all the sandstone materials are loaded, the central controller sends voice and graphical instructions to the driver through the audible and visual alarm, prompting the driver to complete the loading, and prints out the loading document.

[0061] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made thereto without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
