Detailed Implementation
[0023] 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.
[0024] Reference Figures 1-2 The present invention provides an embodiment of a self-unloading cargo box, including a box body 1, a plurality of box side plates 2 rotatably connected to the side wall of the box body 1, a discharge chute 3 is provided inside the box side plate 2, and a connecting component is provided on the side wall of the discharge chute 3.
[0025] The connecting assembly includes a fixing frame 5, which is fixedly connected to the side wall of the side panel 2 of the box. Multiple turntables 6 are rotatably connected to the side wall of the fixing frame 5. An electric push rod 4 is fixedly connected to the side wall of the side panel 2 of the box. The output end of the electric push rod 4 is rotatably connected to the bottom of the turntable 6. A connecting rod 7 is rotatably connected to the side wall of each turntable 6. A rotating plate 8 is rotatably connected to the other end of the connecting rod 7. Gears 9 are fixedly connected to the side wall of each rotating plate 8. Multiple gears 9 mesh with each other. A clamping plate 10 is fixedly connected to the side wall of each turntable 6. A protective assembly is provided inside the box body 1.
[0026] Specifically, when unloading mobile goods, the electric push rod 4 acts on the bottom of the turntable 6. The turntable 6 is connected to the side wall of the fixed frame 5 via a specially designed rotating shaft. Under the push force of the push rod, it rotates clockwise around the shaft at a certain angle on the side wall of the fixed frame 5. During the rotation of the turntable 6, the connecting rod 7 connected to one end is pulled, and the connecting rod 7 is displaced accordingly. The other end of the connecting rod 7 is connected to the rotating plate 8. Driven by the connecting rod 7, the rotating plate 8 rotates around its connection point with the fixed frame 5. Gears 9 are installed on the side wall of the rotating plate 8. The rotation of plate 8 causes gear 9 to rotate around its central axis. Since the two gears 9 mesh with each other, when one gear 9 rotates, the interaction force between the teeth drives the other gear 9 to rotate synchronously, thereby causing the turntables 6 on both sides of the fixed frame 5 to rotate synchronously. After the turntables 6 have moved into place, the clamping plates 10 installed on the turntables 6 will move towards the middle to firmly fix the cargo bin or pipe. The goods are transported in the fixed cargo bin or pipe throughout the unloading process, avoiding spillage during transfer and significantly improving the efficiency of unloading mobile goods in the self-unloading freight container.
[0027] Reference Figure 3 The protective assembly includes connectors 11, multiple connectors 11 are fixedly connected inside the housing 1, each connector 11 has a side platform 12 fixedly connected to its side wall, a fixing post 13 is fixedly connected inside the side platform 12, multiple slip rings 14 are slidably connected to the inner outer wall of the fixing post 13, a fixing member 16 is fixedly connected to the side wall of each slip ring 14, multiple dampers 20 are fixedly connected to the side wall of the side platform 12, an outer plate 19 is fixedly connected to the output end of the damper 20, multiple fixing members 28 are fixedly connected to the side wall of the outer plate 19, a push-pull rod 17 is rotatably connected inside the fixing member 28, the other end of the push-pull rod 17 is rotatably connected to the inside of the fixing member 16, a spring 15 is sleeved on the outer wall of the fixing post 13, one end of the spring 15 is fixedly connected to the side wall of the slip ring 14, and the other end of the spring 15 is fixedly connected to the side wall of another slip ring 14.
[0028] Specifically, when the goods inside the container 1 come into contact with the outer panel 19 during transportation due to vehicle bumps, sudden braking, or other reasons, multiple dampers 20 begin to function. The dampers 20 are evenly distributed between the outer panel 19 and the inner wall of the container 1. The damping medium inside them can absorb the impact force generated by the collision of the goods, providing initial protection for the goods through buffering. Furthermore, when the outer panel 19 is subjected to force and moves towards the inner wall of the container 1, the connection between the push-pull rod 17 and the fixing part 18 rotates inside the fixing part 18 around a specific rotation axis. The rotation of the push-pull rod 17 then pushes the fixing part 1... 16. Fixing component 16 is connected to slip ring 14. Slip ring 14 is fitted on the outer wall of fixing post 13. Under the push of fixing component 16, slip ring 14 slides relative to the outer wall of fixing post 13, while compressing spring 15. Spring 15 has good elasticity and accumulates elastic potential energy after being compressed. When the impact force weakens, spring 15 releases energy by elastic force, pushing slip ring 14 to reset. In this process, the impact force is transferred twice, further reducing the impact on the goods, achieving effective protection of the goods, ensuring the integrity of the goods, and reducing economic losses caused by damage to the goods.
[0029] Working principle: When unloading mobile goods, the electric push rod 4 is activated. The electric push rod 4 outputs power to the turntable 6, pushing the bottom of the turntable 6. The turntable 6 rotates on the side wall of the fixed frame 5 and pulls the connecting rod 7. The connecting rod 7 then pulls the rotating plate 8, causing the gear 9 on the side wall of the rotating plate 8 to rotate. At this time, another gear 9 is pushed to rotate, making the turntables 6 on both sides of the fixed frame 5 move synchronously. The clamping plate 10 fixes the hopper or pipe, preventing the goods from spilling during the transfer process and improving the unloading efficiency of the self-unloading cargo container. The efficiency of mobile cargo is achieved by using multiple dampers 20 to buffer the cargo when it comes into contact with the outer panel 19 inside the container 1. When the outer panel 19 is subjected to force and moves towards the inner wall of the container 1, the push-pull rod 17 will first rotate inside the fixing part 2 18 and push the fixing part 1 16, so that the slip ring 14 slides relative to the outer wall of the fixing post 13. The elastic force of the spring 15 will reset it and transfer the impact force a second time, thus achieving effective protection of the cargo, ensuring the integrity of the cargo, and reducing economic losses caused by cargo damage.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
