Two mounting blocks 401 are fixedly connected to both sides of the frame 1. Sliding rods 402 are slidably connected to the mounting blocks 401. A positioning plate 403 is fixedly connected between the two sliding rods 402 and is slidably connected to the frame 1. Two third hydraulic rods 404 are fixedly connected to the top of the frame 1. The telescopic ends of the third hydraulic rods 404 are fixedly connected to the adjacent positioning plates 403. Two positioning blocks 405 are fixedly connected to the positioning plates 403. An opening and closing structure 3 is provided on the frame 1. The positioning blocks 405 are interconnected with the opening and closing structure 3. The positioning plates 403 are L-shaped. The structure features two symmetrically arranged positioning plates 403. The third hydraulic rod 404 at the top of the frame 1 is activated, causing its telescopic end to slide the positioning plate 403 along the frame 1. Simultaneously, the positioning plate 403 drives the sliding rod 402 to slide on the mounting block 401 until the positioning plate 403 contacts both sides of the door frame 302. Two sliding grooves 406 are provided on both sides of the door frame 302. The sliding grooves 406 engage with adjacent positioning blocks 405. The positioning blocks 405 on the positioning plate 403 engage with the sliding grooves 406 on both sides of the door frame 302, thus positioning the door frame 302 and preventing the top cover from failing to close due to box expansion. This also improves stability during use and avoids uneven force on the second hydraulic rod 308.

By controlling the expansion and contraction of the second hydraulic rods 308 on both sides of the frame 1, the door frame 302 is driven to rotate via the hinges 301 to open the door frame 302, thereby realizing the opening and closing of the door frame 302 and facilitating the loading and unloading of garbage. The first cover plate 304 on the back of the mounting frame 303 can prevent garbage from overflowing. Then, the first hydraulic rods 307 on the top of the mounting frame 303 are controlled to expand and contract, driving the rotating frame 305 to rotate so that the second cover plate 306 slides relatively with the door frame 302, further expanding the opening for loading garbage. Both the mounting frame 303 and the rotating frame 305 are in an "H"-shaped structure, the two first hydraulic rods 307 are symmetrically arranged, the door frame 302 is in a "square"-shaped structure, and both sides of the door frame 302 are respectively against the adjacent positioning plates 403.

The side beams 201 on the frame 1 are made of manganese steel plate, which has high material toughness and will not crack when collided by loading equipment. Steel plates 203 are attached to the front and back of the rear column wing surface of the frame 1 for reinforcement, which reduces the deformation of the rear column when the cargo compartment expands. Meanwhile, the inner side of the compartment wall 202 is reinforced by the reinforcing plates 204 and the angle irons 205, which can enhance the overall compression resistance of the compartment body and reduce the deformation of the compartment body.

Finally, the third hydraulic rod 404 at the top of the frame 1 is activated, causing its extension and retraction end to... The movable positioning plate 403 slides along the frame 1, and at the same time, the positioning plate 403 drives the sliding rod 402 to slide on the mounting block 401 until the positioning plate 403 abuts against both sides of the door frame 302, and the positioning block 405 on the positioning plate 403 engages with the sliding groove 406 on both sides of the door frame 302 to achieve positioning of the door frame 302, avoiding the box from expanding and causing the top cover to fail to close. During the entire use, it also improves stability and avoids uneven force on the second hydraulic rod 308. The side beam 201 on the frame 1 is made of manganese plate, which has high toughness and will not crack when the loading equipment collides. The rear column wings of the frame 1 are reinforced with steel plates 203 on the front and back, reducing the deformation of the rear column when the box expands. At the same time, the inner side of the box wall 202 is reinforced by reinforcing plates 204 and angle irons 205, which can enhance the overall pressure resistance of the box and reduce the deformation of the box.
