[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of this utility model, and to facilitate its implementation.

[0024] It should be noted that in the following embodiments, the terms "first," "second," and "third" do not represent an absolute distinction in structure and / or function, nor do they represent the order of execution; they are merely for the convenience of description.

[0025] like Figures 1 to 4 As shown, this utility model provides a self-unloading material box, including a box body 1, two boxes 2 rotatably connected to the bottom of the box body 1, and a linkage device for controlling the switching of the two boxes 2 between a released state and a locked state. The linkage device includes a movable hook plate 3 rotatably disposed on the box body 1, a locking groove 4 disposed on the movable hook plate 3, and a locking pin 5 disposed on the box 2 that is embedded in the locking groove 4 when in the locked state.

[0026] Specifically, such as Figures 1 to 4 As shown, the box 1 is a rectangular frame structure with openings at both the top and bottom and a hollow interior. Two doors 2 are located at the bottom of the box 1 and are used to control the opening and closing of the bottom openings of the box 1. One end of the door 2 is rotatably connected to the box 1, and the locking pin 5 is fixedly installed at the other end of the door 2. The rotation center line of the movable hook plate 3 is parallel to the rotation center line of the door 2. The movable hook plate 3 is installed on the box 1 via a first rotating shaft 6, and the door 2 is installed on the box 1 via a second rotating shaft 7. The first rotating shaft 6 is located between the second rotating shafts 7 of the two doors 2. The axes of the first rotating shaft 6, the second rotating shaft 7, and the locking pin 5 are parallel. This layout not only optimizes space utilization but also improves the compactness and stability of the structure.

[0027] The locking groove 4 is located below the first rotating shaft 6. Two locking grooves 4 are provided, positioned between the two second rotating shafts 7. Each locking groove 4 is used to insert a locking pin 5 from one of the boxes 2. When the boxes 2 are locked, both boxes 2 close the bottom opening of the box 1, and the locking pins 5 on both boxes 2 are inserted into the locking grooves 4. The two boxes 2 are at the same horizontal level, ensuring the sealing of the box 1. When unloading is required, the movable hook plate 3 is rotated, separating it from the locking pin 5. The locking pin 5 moves out of the locking groove 4, and then the boxes 2 can be rotated downwards, switching from the locked state to the released state, opening the bottom opening of the box 1, allowing the material inside the box 1 to fall downwards. The advantage of this structural design lies in its high flexibility and convenience. When unloading is required, simply rotating the movable hook plate 3 separates it from the locking pin 5, allowing the locking pin 5 to be easily removed from the locking groove 4. At this point, the door 2 can rotate freely downwards, switching from the locked state to the released state, thereby quickly opening the opening at the bottom of the box 1, allowing the material to fall smoothly downwards. This process is not only simple to operate, but also greatly improves unloading efficiency.

[0028] like Figures 1 to 4As shown, the linkage device also includes a connecting rod 8 rotatably connected to the movable hook plate 3. The connecting rod 8 is rotatably mounted on the housing 1. The connecting rod 8 is mounted on the housing 1 via a third rotating shaft 15, which is parallel to the first rotating shaft 6, and its height is greater than that of the first rotating shaft 6. A pin is provided on the movable hook plate 3, and a pin hole 9 is provided at the lower end of the connecting rod 8 for inserting the pin. The axis of the pin is parallel to the axis of the third rotating shaft 15, and the pin hole 9 is an oblong hole with a length greater than the diameter of the pin. The movable hook plate 3 has an L-shaped structure, with the pin mounted at one end and a locking groove 4 located at the other end. The first rotating shaft 6 is mounted at the corner of the movable hook plate 3, between the two ends. The upper end of the connecting rod 8 is used to receive an externally applied operating force to rotate the connecting rod 8. Waste dumping poses risks such as waste splashing. The linkage device can be operated remotely, making it convenient for users and protecting personnel safety. For example, by connecting a rope to the upper end of the connecting rod 8 and pulling the rope remotely, the rope drives the connecting rod 8 to rotate. The connecting rod 8 then tilts up, causing the movable hook plate 3 to rotate. The movable hook plate 3 separates from the locking pin 5, releasing the two box doors 2 at the bottom of the box body 1.

[0029] like Figures 1 to 4 As shown, the linkage device also includes an elastic element 10 connected to the connecting rod 8, and the elastic element 10 is connected to the housing 1. In this embodiment, the elastic element 10 is a tension spring. The elastic element 10 is used to reset the connecting rod 8. One end of the elastic element 10 is connected to the upper end of the connecting rod 8, and the other end of the elastic element 10 is connected to the housing 1. Moreover, after the housing door 2 is closed, under the elastic force applied by the elastic element 10, the movable hook plate 3 can always hook the two locking pins 5, keeping the housing door 2 in the locked state and ensuring that the movable hook plate 3 will not be opened arbitrarily due to transportation shaking or other factors.

[0030] like Figures 1 to 4 As shown, two linkage devices are provided. Two locking pins 5 are installed on the door 2, extending towards both sides of the door 2 and engaging with the movable hook plates 3 of the two linkage devices. The box body 1 is located between the two movable hook plates 3. The connecting rods 8 of the two linkage devices are connected as a whole by a linkage rod 14, allowing the two connecting rods 8 to rotate synchronously. This forms a system that rotates synchronously as a whole. This design ensures that when one linkage device is operated, the other linkage device will respond synchronously, achieving synchronous opening and closing of the two door 2. This synchronicity not only improves operational efficiency but also ensures the stability and balance of the door 2 during opening and closing.

[0031] like Figures 1 to 4As shown, a support frame 11 is provided on the door 2, and a first roller 12 and a second roller 13 are provided on the support frame 11. When the door 2 is locked, the support frame 11, the first roller 12, and the second roller 13 are located below the door 2, and the height of the first roller 12 is less than the height of the second roller 13. At least one first roller 12 and at least one second roller 13 are provided.

[0032] In this embodiment, the support frame 11 is provided with two first rollers 12 and one second roller 13, with the second roller 13 located between the two first rollers 12.

[0033] After unloading, the container 1 is placed on the ground, and the two bottom doors 2 automatically return to their positions, eliminating the need for additional manual operation. The two doors 2 are equipped with two sets of roller structures at different angles. During the descent of the container 1, the first roller 12 and the second roller 13 at the bottom contact the ground. The first roller 12 and the second roller 13 roll at the included angle of the contact surface, pushing the doors 2 upward and rotating them, thus achieving automatic closing and returning the doors 2 to their positions.

[0034] After the door 2 automatically returns to its original position, the movable hook plate 3 automatically locks the door 2, eliminating the need for additional manual operation. The opening of the movable hook plate 3 has a rounded, gradually inclined surface. When the door 2 closes, the locking pin 5 contacts the inclined surface on the movable hook plate 3, pushing the movable hook plate 3 to rotate. The movable hook plate 3 opens, and finally the locking pin 5 is embedded in the locking groove 4, achieving the return to its original position.

[0035] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
