[0036] like Figure 1-Figure 6As shown, this embodiment provides a garbage compression box, including a box body 200 and a sealing door 100. This embodiment also provides a sealing door of the garbage compression box, including a main door 1 and a secondary door 2, and the main door 1 is sealed and connected to the box body 200. The main door 1 is provided with an opening 11, and a slide groove 12 is provided on both sides of the opening 11. The slide groove 12 is extended in the vertical direction. A first inclined surface 13 is provided at the bottom of the opening 11, and an upper sealing plate 14 is provided above the opening 11. A second inclined surface 15 is provided at the bottom of the slide groove 12 along the vertical direction, and the second inclined surface 15 is inclined downward from the outside to the opening 11. The two sides of the secondary door 2 are correspondingly slidably connected to the two slide grooves 12, and the bottom of the secondary door 2 is provided with a wedge-shaped edge 21 adapted to the second inclined surface 15. When the secondary door 2 blocks the opening 11, the bottom of the secondary door 2 abuts against the first inclined surface 13, the top abuts against the upper sealing plate 14, and the two sides are arranged in the slide groove 12, and the wedge-shaped edge 21 abuts against the second inclined surface 15.

[0037] When loading garbage, the auxiliary door 2 moves upward along the chute 12 under the drive of the top driving mechanism of the garbage compression station until it is fully opened, that is, the opening 11 is open; then, the garbage is compressed and sent into the box 200 under the push of the garbage compression station; finally, the auxiliary door 2 moves downward along the chute 12 under the drive of the top driving mechanism of the garbage compression station until it is fully closed, that is, the opening 11 is blocked by the auxiliary door 2. When unloading garbage, the main door 1 is opened and then closed.

[0038] The above structure realizes the docking of the auxiliary door 2 with the garbage compression station and the docking of the main door 1 with the garbage treatment plant, and the structure is simple. The top driving mechanism of the garbage compression station is the existing technology, which can be a manipulator that can grasp the auxiliary door 2 and move it up and down, which is easy to operate. The auxiliary door 2 moves in the slide 12, which ensures the movement accuracy, facilitates the cooperation between the auxiliary door 2 and the main door 1, and ensures the tightness of the connection between the two.

[0039] By setting the first inclined surface 13 and the second inclined surface 15, on the one hand, the auxiliary door 2 moves from top to bottom, and under the action of its own gravity, the bottom of the auxiliary door 2 abuts on the first inclined surface 13 to achieve bottom sealing; the wedge-shaped edge 21 abuts on the second inclined surface 15 to achieve side sealing; the top abuts on the upper sealing plate 14 to achieve top sealing, thereby achieving the sealing of the auxiliary door 2 and the main door 1. The main door 1 and the auxiliary door 2 are sealed and connected, and the main door 1 and the box body 200 are sealed. Under normal conditions, the main door 1 and the box body 200, the main door 1 and the auxiliary door 2 are kept sealed to prevent odor from overflowing during transportation. On the other hand, it is not easy to accumulate garbage at the opening 11 of the main door 1, which can effectively prevent the auxiliary door 2 from being stuck. Even if garbage is accumulated at the opening 11, when the auxiliary door 2 moves downward, the bottom of the auxiliary door 2 will push the garbage away.

[0040] The upper sealing plate 14 is provided with a baffle 19, and the top of the auxiliary door 2 is provided with a folded edge 23. When the auxiliary door 2 blocks the opening 11, the baffle 19 is arranged under the folded edge 23 to prevent the auxiliary door 2 from moving upward to interfere with the structure of the baffle 19 during the opening process, and the folded edge 23 abuts against the baffle 19 to ensure the tight connection between the two at the top of the auxiliary door 2, which can further prevent the internal odor from overflowing.

[0041] The sealing door 100 further includes a first sealing strip 3, which is coated on the outer periphery of the auxiliary door 2, so that the first sealing strip 3 is clamped between the folded edge 23 and the stop strip 19, between the auxiliary door 2 and the slide groove 12, between the bottom of the auxiliary door 2 and the first inclined surface 13, and between the wedge edge 21 and the second inclined surface 15. Specifically, the first sealing strip 3 includes a side sealing strip 31 and a bottom sealing strip 32. The auxiliary door 2 is in a plate shape, and the top and both sides of the auxiliary door 2 are provided with folded edges 23. The side sealing strip 31 is provided at the folded edge 23, and the bottom sealing strip 32 is provided at the bottom and the wedge edge 21 of the auxiliary door 2. By providing the side sealing strip 31, further sealing between the folded edge 23 and the slide groove 12 and the upper sealing plate 14 is achieved, and by providing the bottom sealing strip 32, further sealing between the bottom of the auxiliary door 2 and the first inclined surface 13 and between the wedge edge 21 and the second inclined surface 15 is achieved.

[0042] The first inclined surface 13 is inclined downward from the outside to the inside. When the secondary door 2 moves downward, the garbage is pushed away to the inside of the box body 200, preventing the garbage from falling outside, and keeping the external environment clean. Furthermore, the main door 1 is also provided with a third inclined surface 18, which is provided on the side facing the box body 200, that is, it is continuously provided with the first inclined surface 13 and the inclination angle of the third inclined surface 18 is smaller than the inclination angle of the first inclined surface 13, further effectively preventing garbage from accumulating at the opening 11 of the main door 1, and effectively preventing the secondary door 2 from being stuck.

[0043] A docking port 22 is provided on the side of the auxiliary door 2 facing away from the box body 200. The docking port 22 is used to dock with an external structure such as the top drive mechanism of the garbage compression station to facilitate opening or closing of the auxiliary door 2. A baffle 16 is also provided on the main door 1. The auxiliary door 2 can be inserted between the upper sealing plate 14 and the baffle 16. When the auxiliary door 2 is in a closed state, the interface is located above the baffle 16. The docking port 22 is prevented from structural interference with the baffle 16 when connected to the external structure, and the baffle 16 can limit the downward movement of the interface, thereby playing a role in limiting the downward movement of the auxiliary door 2. Specifically, the docking port 22 is a protrusion provided on the side of the auxiliary door 2 facing away from the folding edge 23. Two docking ports 22 are provided to improve the reliability of connection with the external structure.

[0044] A second annular sealing strip 4 is provided on the side of the main door 1 facing the box body 200. The second sealing strip 4 is located around the opening 11. The main door 1 is sealed to the box body 200 via the second sealing strip 4. The second sealing strip 4 is pressed between the main door 1 and the box body 200, thereby achieving sealing.

[0045] The garbage compression box also includes a locking assembly 300, which includes a locking drive 301, a locking rod 302 and at least one locking pin 303. The fixed end of the locking drive 301 is fixed to the box body 200, and the movable end is connected to the locking rod 302. At least one locking pin 303 is connected to the locking rod 302 along the length direction of the locking rod 302. The main door 1 is provided with at least one locking block 17, and the locking block 17 is arranged one-to-one with the locking pin 303. For example, two locking pins 303 and two locking blocks 17 are provided, and the locking block 17 is provided with a locking hole 171. The locking drive 301 drives the locking rod 302 to move, so that the two locking pins 303 are correspondingly plugged into the two locking holes 171. For example, the locking drive 301 is a cylinder or an oil cylinder, the cylinder body is connected to the box body 200, and the telescopic rod is connected to the locking rod 302. The lock hole 171 is wedge-shaped, and the locking pin 303 matches the shape of the lock hole 171. The locking pin 303 is inserted into the lock hole 171 in the vertical direction, which facilitates the close insertion and separation of the two. When the locking pin 303 is inserted into the lock hole 171, the second sealing strip 4 on the main door 1 is forced to be close to the box body 200 to achieve sealing.

[0046] When it is necessary to unload garbage, before opening the main door 1, the locking latch 303 moves upward under the drive of the locking drive 301, and the locking latch 303 is pulled out from the lock hole 171 to achieve unlocking; after closing the main door 1, the locking latch 303 moves downward under the drive of the locking drive 301, and the locking latch 303 is inserted into the lock hole 171 to achieve locking. By setting the locking assembly 300 and the locking block 17, the locking between the main door 1 and the box body 200 is achieved. By setting the locking rod 302, a plurality of locking latches 303 are provided on the locking rod 302, and a plurality of locking blocks 17 are provided accordingly, so as to improve the reliability of locking, and a plurality of locking blocks 17 can be moved simultaneously by a locking drive 301, thereby simplifying the structure.

[0047] Optionally, locking blocks 17 are provided on both sides of the main door 1, and locking assemblies 300 are provided on both sides of the box body 200, which further provide locking reliability. The main door 1 can be locked or unlocked by locking or unlocking both sides at the same time.

[0048] The garbage compression box also includes a main driving member 400, the main door 1 is rotatably connected to the box body 200, the fixed end of the main driving member 400 is fixed to the box body 200 and is arranged above the locking assembly 300, the telescopic end is fixed to the main door 1, the telescopic end extends to drive the main door 1 to open, and the telescopic end retracts to drive the main door 1 to close, the main driving member 400 can be an oil cylinder or an air cylinder, the cylinder body is connected to the box body 200, and the telescopic rod is connected to the main door 1. The main door 1 and the auxiliary door 2 are opened or closed under the driving action of the main driving member 400, realizing the automatic opening and closing of the main door 1.
