[0002] Currently, aggregate loading is often done manually, which is inefficient and poses safety risks to workers. To improve the efficiency and safety of aggregate loading and reduce manual intervention, this device uses visual recognition technology to detect the material level in real time and uses a PLC to automate the start and stop of the loading equipment. This ensures precise control of the amount of aggregate piled in the truck bed, making the loading process more standardized. Therefore, a visual recognition aggregate loading level device is needed to solve the above problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a visual recognition device for aggregate loading positions, which solves the problems mentioned in the background.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 A visual recognition aggregate loading position device includes: a parking platform 1, a steel speed bump 2 installed on the outer wall of the parking platform 1, a rear parking positioner 3 installed on the outer wall of the parking platform 1, an indicator light 4 on the top of the parking platform 1, a loading hopper 5 placed on the outer wall of the parking platform 1, a unloading platform 6 on the top of the parking platform 1, a protective net 7 connected to the outer wall of the unloading platform 6, a discharge chute 8 on the inner wall of the unloading platform 6, a steel rail 9 installed on the outer wall of the unloading platform 6, and a conveyor 10 on the top of the steel rail 9. The inner wall of the conveyor 10 is equipped with a belt 11, the outer wall of the conveyor 10 is equipped with a rotary motor 12, the inner wall of the belt 11 is fitted with a rotating roller 13, the bottom of the conveyor 10 is movably connected with a pulley 14, the outer wall of the conveyor 10 is connected with a connecting frame 15, the inner wall of the connecting frame 15 is equipped with a discharge hopper 16, the bottom of the conveyor 10 is connected with a mounting frame 17, the outer wall of the mounting frame 17 is equipped with a vision camera 20, the outer wall of the conveyor 10 is connected with a receiving chute 18, and the bottom of the receiving chute 18 is connected with a bulk chute 19.

[0024] The device consists of several steel speed bumps 2, arranged on both sides of the parking platform 1. By arranging these steel speed bumps 2 on both sides of the outer wall of the parking platform 1, and causing the loading hopper 5 to move on the surface of the parking platform 1, the loading hopper 5 will experience a bump each time it moves back and forth. Therefore, if there is no bump during the movement of the loading hopper 5, it may indicate that the loading hopper 5 has shifted position.

[0025] The rear parking positioner 3 is level with the middle section of the loading hopper 5 and is located on one side of the parking platform 1. When the loading hopper 5 moves backward, the rear parking positioner 3 is used to detect the position of the rear half of the loading hopper 5, so that the rear parking positioner 3 is at the same height as the loading hopper 5.

[0026] The indicator light 4 is electrically connected to the rear parking locator 3 and the vision camera 20, and the rear parking locator 3 and the vision camera 20 control the reaction light of the indicator light 4. When the loading hopper 5 on the device moves to the position detected by the rear parking locator 3, the indicator light 4 automatically flashes a stop indicator light. When the vision camera 20 subsequently detects the material accumulation in the inner cavity of the loading hopper 5, the reversing indicator light of the indicator light 4 is automatically triggered, or the indicator light 4 remains stationary, thereby causing the bulk chute 19 on the device to move.

[0027] The device comprises several pulleys 14, which are arranged at the bottom of two conveyors 10. The pulleys 14 on the device contact the outer wall of the rail 9 at the bottom of the conveyor 10. When the bulk chute 19 needs to be moved, the pulleys 14 on the device move in a straight line and short distance along the outer wall of the rail 9. After each movement, the bulk chute 19 reaches the next predetermined feeding position.

[0028] The inner diameter of the feeding trough 8 is larger than that of the bulk chute 19, and the bulk chute 19 moves back and forth within the inner cavity of the feeding trough 8. The receiving trough 18 and the bulk chute 19 are moved simultaneously by the pulley 14 on the device, and the bulk chute 19 moves within a limited range within the inner cavity of the feeding trough 8, thus completing a positioning and feeding operation after each movement.

[0029] The rotary motor 12 has a power output shaft connected to a rotating roller 13, and the outer wall of the rotating roller 13 is sleeved with the belt 11. When the rotary motor 12 outputs rotational power, the rotating roller 13 drives the belt 11 to rotate, thereby causing the hopper 16 to convey the aggregate to the surface of the belt 11, and the aggregate is transferred to the inner cavity of the receiving trough 18 on the surface of the belt 11.

[0030] The bottom of the unloading platform 6 is connected to a scanner 21, which is positioned above the loading hopper 5. By positioning the scanner 21 above the loading hopper 5, the scanner 21 can detect whether the loading hopper 5 has moved to the appropriate position.

[0031] The working principle is as follows: First, by setting up structures such as a rear parking locator 3, an indicator light 4, and a loading hopper 5, when the loading hopper 5 initially reaches the top of the parking platform 1, the rear parking locator 3 detects the real-time position of the loading hopper 5 and sends feedback to the indicator light 4, prompting the driver to stop. This allows the loading hopper 5 to be precisely positioned and ready for loading. Then, by setting up structures such as pulleys 14, rails 9, a bulk chute 19, and a vision camera 20, the bulk chute 19 loads the aggregate during the loading process. The system uses a vision camera 20 to visually identify the accumulation of aggregate in the inner cavity of the loading hopper 5. When the accumulation height reaches a certain level, the system automatically triggers the pulley 14 to move along the outer wall of the rail 9. This allows the bulk chute 19 on the device to move a short distance above the loading hopper 5 before resuming the loading operation. If the device does not have pulleys 14 and rails 9, the vision camera 20 can be electrically connected to the indicator light 4. After each visual identification by the vision camera 20, the indicator light 4 will prompt the driver to move the loading hopper 5 backward a certain distance before resuming the loading operation.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
