[0002] The cargo box of the existing domestic garbage transport vehicle is provided with a garbage loading port and a sealing cover for closing the garbage loading port. The sealing cover mainly has two structures: an upside-down flip opening and closing type and a horizontal push-pull opening and closing type.
[0003] The sealing cover that opens and closes by flipping up and down takes up a large space when flipped upward to open. There needs to be enough space above the cargo box when the cover is opened, which makes it impossible to seal and connect with the vertical loading funnel in the garbage transfer station that leads the garbage into the cargo box.
[0004] The horizontal push-pull opening and closing sealing cover does not occupy the upper space of the cargo box when the sealing cover is opened, so that the garbage loading port can be sealed and connected with the vertical loading funnel in the garbage transfer station that leads the garbage into the cargo box. However, in the closed state, the sealing cover is not tightly pressed on the garbage loading port, and there is a fitting gap between the sealing cover and the garbage loading port. Domestic garbage will emit odor in the cargo box, and these odors will escape from the fitting gap between the sealing cover and the garbage loading port, causing air pollution. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] In this embodiment, the garbage truck cargo box loading port sealing device includes a sealing cover for sealing the garbage loading port 1 on the top of the cargo box and a linear actuator 2 for driving the sealing cover in the forward and backward directions of the cargo box. In this embodiment, the linear actuator 2 is a hydraulic cylinder. Of course, in different embodiments, the linear actuator 2 can also be a pneumatic cylinder, a chain drive mechanism, or an electric screw.
[0026] The sealing cover includes a rectangular outer frame 3 and a rectangular inner cover 4. The rectangular inner cover is embedded in the rectangular outer frame and slides up and down with the rectangular outer frame. A spring 5 for supporting the rectangular inner cover is provided on the rectangular outer frame. The rectangular outer frame is connected to the linear drive.
[0027] A rectangular elastic sealing ring 6 is provided on the outside of the garbage loading port for cooperating with the rectangular inner cover.
[0028] The garbage truck cargo box loading port sealing device also includes a pressure-applying structure for driving the rectangular inner cover downward to press against the rectangular elastic sealing ring. In this embodiment, the pressure-applying structure includes a rectangular frame opening 7 disposed at the top of the cargo box and located at the edge of the garbage loading port. The inner side of the rectangular frame opening is provided with a guide slot 8 that slidably engages with the sealing cover. The front portion of the guide slot is provided with a first inclined surface 9 for driving the rectangular inner cover downward. The rear portion of the guide slot is provided with a second inclined surface 10 for driving the rectangular inner cover downward. The front portion of the rectangular inner cover is provided with a front inclined surface 11 for engaging with the first inclined surface. The rear portion of the rectangular inner cover is provided with a rear inclined surface 12 for engaging with the second inclined surface.
[0029] The operating principle of the opening and closing cover of the sealing device for the loading port of the garbage truck cargo box in this embodiment is as follows:
[0030] When closing the lid, the linear actuator 2 drives the sealing lid forward along the guide slot 8. During the forward movement, the rectangular inner lid 4, supported by the spring 5, first slides against the top surface of the guide slot 8, and the bottom surface of the rectangular inner lid 4 shrinks into the rectangular outer frame 3, while the rectangular outer frame 3 slides against the bottom surface of the guide slot 8 (the bottom surface of the guide slot 8 can be the top surface of the cargo box), and the side surfaces of the rectangular outer frame 3 cooperate with the side surfaces of the guide slot 8 to guide the movement direction; when the front inclined surface 11 of the rectangular inner lid contacts the first inclined surface 9 on the guide slot, and the rear inclined surface 12 of the rectangular inner lid contacts the second inclined surface 10 of the guide slot, the rectangular inner lid 4 begins to move downward under the push of the first inclined surface 9 and the second inclined surface 10, and gradually presses against the rectangular elastic sealing ring 6, thereby closing the garbage loading port 1.
[0031] When opening the cover, the linear drive 2 drives the sealing cover to move backward along the guide slot 8. During the process in which the front inclined surface 11 of the rectangular inner cover gradually separates from the first inclined surface 9 on the guide slot and the rear inclined surface 12 of the rectangular inner cover gradually separates from the second inclined surface 10 of the guide slot, the rectangular inner cover 4 gradually moves upward and resets under the thrust of the spring 5; and the sealing cover as a whole finally opens the garbage loading port 1 under the rear pull of the linear drive 2.
[0032] The garbage truck cargo box loading port sealing device in this embodiment has a rectangular inner cover of the sealing cover that can be pressed against the rectangular elastic sealing ring on the outside of the cargo box loading port under the action of the pressure structure, thereby ensuring the airtightness of the cargo box loading port and preventing the odor in the cargo box from escaping from the cargo box, which is environmentally friendly.
[0033] The sealing device for the loading port of the cargo box of the garbage transport truck in this embodiment has a sealing cover that does not occupy the space above the rectangular frame opening, so that the rectangular frame opening can be sealed and docked with the vertical loading funnel in the garbage transfer station that leads the garbage into the cargo box. After the sealing docking, the leakage of garbage odor from the rectangular frame opening and the vertical loading funnel during loading can be avoided, and the garbage loading is environmentally friendly.
[0034] As an improvement to the above embodiment, the top surface of the rectangular elastic sealing ring 6 is lower than the bottom surface of the rectangular outer frame 3. This improvement can avoid contact between the rectangular outer frame 3 and the rectangular elastic sealing ring 6 during the sliding process of the sealing cover, thereby protecting the rectangular elastic sealing ring 6 and extending its service life.
[0035] As an improvement to the above embodiment, a rectangular annular platform 13 is provided on the bottom of the rectangular inner cover, which mates with the top surface of the rectangular elastic sealing ring. The rectangular annular platform has a smaller area, making it easier to process its surface to a smooth and flat surface during implementation. This reduces wear on the sealing ring surface during contact and improves the fit between the rectangular annular platform and the rectangular elastic sealing ring, resulting in better sealing performance.
[0036] As an improvement to the above embodiment, a stop plate 14 is further connected to the rear portion of the rectangular outer frame to limit the upward movement of the rectangular inner cover. When the cover is open, the front end of the rectangular inner cover 4 is located within the rear end of the guide slot 8, and the rear end of the rectangular inner cover 4 is pressed by the stop plate 14. This better ensures that the rectangular inner cover 4 is in a horizontal position, allowing the rectangular inner cover 4 to slide more smoothly into the guide slot 8 when the cover is closed.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
