Description
Technical Field
[0001] The invention relates to the field of material transport and loading and unloading structures, and in particular to a structure for transporting and loading and unloading powder and granular materials on a bulk trailer. Background Art
[0002] In order to facilitate the storage and transportation of materials such as particles and powders, the existing market usually uses carriage liner bags for loading and unloading of materials. The existing loading and unloading structure is generally a three-dimensional liner bag with six sides. The existing liner bag is provided with a discharge port at the bottom for the convenience of unloading. However, the existing discharge port is mostly directly placed in the feed channel of the storage box during unloading. It is easy to cause a gap between the discharge port and the feed channel due to the difference in size, thereby causing leakage and pollution. In addition, the existing discharge port lacks a sealing function. When the storage box is displaced due to external reasons when the material is moved, the discharge port will continue to discharge the material outward, making it impossible to stop the leakage of the material in time, thereby increasing the degree of pollution and loss. Existing loading and unloading structural devices, such as the Chinese invention disclosed in CN107284880A, involve a container liner bag, which includes an inner tube, partition wall and rear wall of the liner bag are equipped with different reinforcement structures when in use, and are hung in the container through hanging parts, and the square tube plays a further role in supporting, hanging and improving the strength. When unloading, the liner bag is not easy to deform, making the unloading process smoother. The loading and unloading of the square tube is convenient and fast The above application does not mention a solution for avoiding contamination when the loading and unloading mechanism discharges materials, nor does it propose a solution for sealing the processing port after it has leaked outwards. Therefore, further improvements are needed on the loading and unloading structure for powder and granular materials. Summary of the invention

[0012] 2. A rotating rod is fixedly connected to the hinge between the upper end of the left vertical plate and the horizontal plate. The rotating rod passes through the interior of the horizontal plate and passes outward. A cylindrical cavity for accommodating the rotating rod is opened inside the horizontal plate. A baffle extending outward is arranged on the lower side of the rotating rod. A card block that passes through the cylindrical cavity is also arranged inside the horizontal plate. The card block is fan-shaped. When the left vertical plate and the horizontal plate rotate relative to each other, the distance between the card block and the baffle can be shortened. A spring is installed between the corresponding card block and the rotating rod baffle in the cylindrical cavity. The left vertical plate has four connections with the right vertical plate and the horizontal plate, so that the spring can exert a force on the baffle and the card block on both sides, so that the vertical plate and the horizontal plate form a horizontal state, and the spring force needs to be overcome to make the vertical plate and the horizontal plate form a 90° angle state.

[0017] The working principle of a structure for transporting and loading and unloading powder and granular materials on a bulk trailer of the present invention is as follows.
[0018] First, a discharge port 4 is provided at the lower right end of the packaging structure 2. The discharge port 4 and the packaging structure 2 are made of the same material. One end of the discharge port 4 extends to the outside of the transport vehicle body 1. The discharge port 4 is rectangular. A sealing device 5 is installed on the outside of the discharge port 4. When unloading, the discharge port 4 can be placed in the feed channel of the unloading storage box for unloading. Horizontal plates 7 are provided on the upper and lower sides of the sealing device 5, a left vertical plate 8 is provided on the left side of the sealing device 5, and a right vertical plate 19 is provided on the right side of the sealing device 5. The upper and lower ends of the left vertical plate 8 and the right vertical plate 19 are hingedly connected to the horizontal plate 7, and the middle ends of the left vertical plate 8 and the right vertical plate 19 are provided with connecting pieces 9, so that the horizontal plate 7 can be rotated with the left and right vertical plates, and the vertical plates can rotate relative to the connection 9, so that the upper and lower sides can be The horizontal plate 7 is in contact with each other, and the upper and lower sides of the vertical plates are also in contact with each other, thereby changing the rectangular sealing device 5 into a horizontal long strip, completing the effect of closing the discharge port, and then a rotating rod 10 is fixedly connected through the hinge between the upper end of the left vertical plate 8 and the horizontal plate 7, and the rotating rod 10 penetrates into the interior of the horizontal plate 7 and penetrates outward. A cylindrical cavity for accommodating the rotating rod 10 is opened inside the horizontal plate 7, and a baffle extending outward is arranged on the lower side of the rotating rod 10. A card block 13 penetrating into the cylindrical cavity is also arranged inside the horizontal plate 7. The card block 13 is fan-shaped. When the left vertical plate 8 and the horizontal plate 7 rotate relative to each other, the distance between the card block 13 and the baffle can be shortened. A spring is installed between the corresponding card block 13 and the baffle of the rotating rod 10 inside the cylindrical cavity. The left vertical plate 8 has four connections with the right vertical plate 19 and the horizontal plate 7, so that The spring can exert a force on the baffles and the card blocks 13 on both sides, so that the vertical plate and the horizontal plate 7 form a horizontal state, and the spring force needs to be overcome to make the vertical plate and the horizontal plate 7 form a 90° angle state. Finally, a pull rope 6 is fixedly connected to one side of the left vertical plate 8 through the connecting piece in the middle of the right vertical plate 19, and the pull rope 6 passes through the connecting piece 9 of the left vertical plate 8. A pull rope cavity 18 is opened inside the connecting piece 9 of the left vertical plate 8. The pull rope cavity 18 is arranged vertically and horizontally inside the connecting piece 8 for the pull rope 6. After entering the pull rope cavity 18, the pull rope 6 needs to be bent 90° to change direction. One side of the pull rope cavity 18 is connected to the outside. After entering the pull rope cavity 18, the pull rope 6 passes through the outside of the sealing device 5. Then, when the staff controls the left vertical plate 8 with one hand and pulls the pull rope 6 with the other hand, the right vertical plate 1 can be closed. After 9 pulls the rear left vertical plate 8 closer, the vertical plate can be driven to overcome the force of the spring at the connection with the horizontal plate 7 to form the sealing device 5 into a rectangular shape, and then a welt airbag 11 is fixedly installed on the outside of the sealing device 5, and baffles 12 are arranged on both sides of the welt airbag 11. The welt airbag 11 is arranged in a rectangular shape, and an intake airbag 15 is installed inside the left vertical plate 8. An inflation valve core 14 is connected to one side of the intake airbag 15. A vent pipe 16 is also arranged on the intake airbag 15. The vent pipe 16 can be used to pass outward and connect with the inside of the welt airbag 11. After the external inflation device is connected with the inflation valve core 14, airflow can be filled into the intake airbag 15, and the airflow can enter the inside of the welt airbag 15 along the vent pipe 16, and the expansion direction of the welt airbag 15 is limited by the baffle 12.The edge airbag 15 can expand outward and contact the inner side of the feed channel of the discharge box, so as to achieve the effect of blocking the gap and preventing discharge. When the edge airbag 15 completes the gap blocking and cannot expand due to obstruction, the subsequent airflow can enter the airbag 15, so that the airbag 15 expands to the upper and lower sides, squeezing the spring and the limit rod 17, so that the limit rod 17 can move downward through the through hole into the rope cavity 18 to press the rope 6, so as to fix the position of the rope 6, thereby fixing the rectangular state of the sealing device 5. When the discharge box is displaced due to external factors, causing the material port 4 to be separated from its feed channel, the edge airbag 11 can lose its expansion restriction, so that the airbag 15 can squeeze the internal airflow into the edge airbag 11 under the action of the spring on one side, so that the force on the limit rod 17 is lost, causing the limit rod 17 to reset and release the pressure on the rope 6, so that the sealing device 5 loses its restriction and becomes a long strip to close the discharge port 4, achieving the effect of stopping the loss in time.
