The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model discloses a marine unloading arm conveying device, comprising: a transfer platform 1 and auxiliary components. Rotary seats 2 are fixedly connected to the four corners of the lower surface of the transfer platform 1. The rotating seats 2 provide rotational support for the first mounting seats 3, allowing the first mounting seats 3 to flexibly adjust the direction of the drive wheels 5. The first mounting seats 3 are rotatably connected to the lower surface of the rotating seats 2. Through this rotatable connection, the first mounting seats 3 drive the drive wheels 5 to achieve steering, adapting to different transport paths. A drive motor 4 is fixedly connected to the side wall of the first mounting seats 3. The drive motor 4 serves as a power source, driving the drive wheels 5 to rotate via its output shaft, providing propulsion power to the transfer platform 1. The output end of the drive motor 4 is fixedly connected to the drive wheels 5. Driven by the drive motor 4, the drive wheels 5 rotate, propelling the transfer platform 1 forward through friction with the ground, thus achieving material transfer. Second mounting seats 9 are fixedly connected to both the front and rear sides of the lower surface of the transfer platform 1. The second mounting base 9 provides a mounting foundation for the first hydraulic pump 6, the rolling wheels 10, and the support plate 8, ensuring the stability of the bottom support structure. The lower surface of the second mounting base 9 is provided with rolling wheels 10, which provide auxiliary support and rolling guidance when the transfer platform 1 moves, reducing ground friction and improving movement flexibility. The first hydraulic pump 6 is fixedly connected to both the left and right sides of the second mounting base 9. The first hydraulic pump 6 drives the first hydraulic rod 7 to extend and retract by outputting hydraulic power, realizing the lifting and lowering adjustment of the support plate 8. The output end of the first hydraulic pump 6 is fixedly connected to the first hydraulic rod 7. The first hydraulic rod 7 extends and retracts under the action of the first hydraulic pump 6, causing the support plate 8 to contact the ground or be lifted, realizing the stable support or movement switching of the device. The lower surface of the first hydraulic rod 7 is fixedly connected to the support plate 8. The support plate 8 contacts the ground under the drive of the first hydraulic rod 7, distributing the weight of the transfer platform 1 and enhancing the stability of the device when loading and unloading materials.

[0025] The drive wheel 5 is located inside the first mounting base 3. The first mounting base 3 provides protection and support for the drive wheel 5, restricts its range of motion, and ensures that the drive wheel 5 rotates safely within a specified space. The first hydraulic pump 6 and the second mounting base 9 are staggered. This layout avoids structural interference between the first hydraulic pump 6 and the second mounting base 9, and facilitates the arrangement of hydraulic pipelines, ensuring the normal operation of the hydraulic system. The support plate 8 is located on the lower surface of the transfer platform 1. After the support plate 8 is lowered into position, it contacts the ground to form a stable support surface, preventing the transfer platform 1 from tilting or shaking under load. The drive motor 4 is located on the outer surface of the first mounting base 3. The exposed drive motor 4 facilitates maintenance and repair, and is fixed by the first mounting base 3 to ensure the stability of power transmission. The number of hydraulic pumps 6 and the number of second mounting seats 9 are set in a corresponding manner. Each second mounting seat 9 is equipped with a first hydraulic pump 6 on both sides to ensure balanced power when the support plate 8 is raised and lowered, avoiding uneven force distribution. The second mounting seat 9 is located inside the first mounting seat 3, and the first mounting seat 3 provides inclusive support for the second mounting seat 9, making the bottom structure compact, reducing space occupation, and improving the rationality of the overall layout. The auxiliary components are located above the transfer platform 1. The auxiliary components realize the material transfer function through the connection with the transfer platform 1 and work together with the bottom moving support structure to complete the unloading task. The auxiliary components include a controller 11, a first connecting seat 12, a second hydraulic pump 13, a second hydraulic rod 14, a second connecting seat 15, a fixing block 16, a connecting column 17, and a mounting frame. 18. The conveying device 19, conveyor belt 20, and reinforcing plate 21 work together to achieve control, lifting, connection, and conveying functions, ensuring the continuity of the unloading process. A controller 11 is fixedly connected to the front surface of the transfer platform 1. The controller 11 serves as the control core, connecting various motors and hydraulic pumps via cables to achieve intelligent control of the movement of the transfer platform 1 and the conveying device 19. First connecting seats 12 are fixedly connected to the front and rear sides of the upper surface of the transfer platform 1. The first connecting seats 12 provide a rotatable connection fulcrum for the second hydraulic pump 13, allowing it to adjust the angle of the second hydraulic rod 14 through pitching motion. The second hydraulic pump 13 is rotatably connected to the upper surface of the first connecting seats 12. The second hydraulic pump 13, through its rotatable connection with the first connecting seats 12, can... The output direction is adjusted to coordinate with the second hydraulic rod 14 to achieve height and angle adjustment of the mounting frame 18. The output end of the second hydraulic pump 13 is fixedly connected to the second hydraulic rod 14. Driven by the second hydraulic pump 13, the second hydraulic rod 14 extends and retracts, driving the mounting frame 18 to rise, fall, or tilt by pushing and pulling the second connecting seat 15. One end of the second hydraulic rod 14 is rotatably connected to the second connecting seat 15. The second connecting seat 15, through its rotatable connection with the second hydraulic rod 14, converts hydraulic power into movement of the mounting frame 18, while allowing a certain angle of oscillation to adapt to different unloading requirements. A reinforcing plate 21 is fixedly connected to the upper surface of the second connecting seat 15, enhancing the connection strength between the second connecting seat 15 and the mounting frame 18 and preventing deformation under stress.To ensure the stable installation of the conveying device 19, a mounting bracket 18 is fixedly connected to the side wall of the reinforcing plate 21. The mounting bracket 18 is firmly connected to the second connecting seat 15 through the reinforcing plate 21, forming a stable support structure to bear the weight of the conveying device 19 and the conveyor belt 20. The conveying device 19 is provided on the inner surface of the mounting bracket 18. The conveying device 19 serves as a power source, driving the conveyor belt 20 to operate, realizing the continuous conveying of materials on the conveyor belt and completing the unloading operation. The conveyor belt 20 is provided on the outer surface of the conveying device 19, and the conveyor belt 20 rotates cyclically under the drive of the conveying device 19. The material is transported from the transfer platform 1 to the target location for unloading. Connecting columns 17 are fixedly connected to both the front and rear sides of the mounting frame 18. The connecting columns 17 provide a rotatable connection point between the mounting frame 18 and the fixed block 16, allowing the mounting frame 18 to rotate around the fixed block 16. This, combined with the hydraulic system, enables multi-angle unloading. One end of the connecting column 17 is rotatably connected to the fixed block 16, and the lower surface of the fixed block 16 is fixed to the transfer platform 1. Through its fixed connection to the transfer platform 1, the fixed block 16 provides a fulcrum for the rotation of the mounting frame 18, limiting its rotation range and ensuring stability.

[0026] The fixing block 16 and the first connecting seat 12 are arranged in parallel. This parallel layout ensures that the mounting frame 18 is subjected to uniform force during rotation and lifting, avoiding structural swaying caused by fulcrum offset and improving the stability of the unloading process. The mounting frame 18 is located between two reinforcing plates 21, which are symmetrically arranged on both sides of the mounting frame 18. The left and right clamps enhance the lateral stability of the mounting frame 18 and prevent it from tilting during material conveying. The size of the conveyor belt 20 is matched with the size of the mounting frame 18 to ensure that the conveyor belt 20 can be tightly fitted to the mounting frame 18, avoiding conveyor belt deviation or loosening due to size deviation and ensuring the reliability of the conveying process. The reinforcing plates 21 are symmetrically arranged on the front and rear sides of the mounting frame 18. The symmetrical reinforcing plates 21 evenly distribute the force on the mounting frame 18, improve the torsional performance of the overall structure, and ensure the stability and safety during unloading. The mounting frame 18 is located in the middle of the upper surface of the transfer platform 1. The central layout makes the weight of the mounting frame 18 evenly distributed on the transfer platform 1, avoiding the center of gravity shift. Together with the bottom support structure, it improves the overall stability of the device. The size of the mounting frame 18 is compatible with the size of the fixing block 16. The compatible size ensures that the rotational connection between the connecting column 17 and the fixing block 16 is tight and reliable, so that the mounting frame 18 moves accurately and stably when adjusting the angle.

[0027] Working principle: First, the device is started by the controller 11, which drives the drive motor 4 to rotate the drive wheel 5. With the assistance of the rolling wheels 10, the transfer platform 1 moves along the preset path to the unloading position. The first hydraulic pump 6 drives the first hydraulic rod 7 to extend, and the support plate 8 descends to contact the ground, providing stable support for the device and ensuring that there is no shaking during the unloading process. The second hydraulic pump 13 drives the second hydraulic rod 14 to extend and retract, which drives the mounting frame 18 to rotate around the fixed block 16 through the second connecting seat 15 and the reinforcing plate 21. The height and angle of the mounting frame 18 are adjusted so that the conveyor belt 20 is aligned with the receiving equipment, ensuring a smooth material transfer path. The conveying device 19 is started, driving the conveyor belt 20 to circulate. The material is transferred from the conveyor belt 20. Loaded at the starting end, the material moves to the end of the conveyor belt 20 and is unloaded into the target storage device. During the transfer process, the reinforcing plate 21 and the connecting column 17 work together to maintain the stability of the mounting frame 18 and prevent tilting or twisting. The direction of the first mounting seat 3 is adjusted by rotating the seat 2, and the orientation of the drive wheel 5 is changed to realize the steering of the transfer platform 1. With the action of the second hydraulic pump 13 and the second hydraulic rod 14, the conveyor belt 20 can be adjusted at multiple angles in the horizontal and vertical directions to adapt to different unloading requirements. After unloading is completed, the first hydraulic pump 6 drives the first hydraulic rod 7 to retract, the support plate 8 is lifted off the ground, the drive motor 4 drives the drive wheel 5 to rotate, and the transfer platform 1 moves to the next working position with the assistance of the rolling wheel 10.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
