Description

Technical Field

[0001] The utility model relates to the technical field of domestic garbage transport vehicles, in particular to a cargo box sealing device of a garbage transport vehicle. Background Art

[0002] The cargo box of the domestic waste transport truck is provided with a garbage loading port. In order to prevent the odor emitted by the domestic waste from leaking from the loading port and polluting the air, the garbage loading port is required to be well sealed during transportation.

[0003] To address the problem of loose sealing of the horizontal push-pull sealing cover on the cargo box of existing domestic waste transport trucks, the applicant previously submitted a utility model patent with application number 2024226413692, entitled "Garbage Transport Truck Cargo Box Loading Port Sealing Device." This patent utilizes an inclined surface structure provided on the rectangular inner cover and the rectangular frame opening to achieve a tight fit between the rectangular inner cover and the rectangular elastic sealing ring, ensuring a good sealing effect. However, during the opening and closing process, the rectangular inner cover in this technical solution needs to slide a certain distance on the rectangular elastic sealing ring, which will cause friction and wear on the rectangular elastic sealing ring, thereby reducing the service life of the rectangular elastic sealing ring.

[0004] In addition, in existing cargo boxes with garbage compression functions, when the push plate of the compression mechanism pushes the garbage in the cargo box to move toward the rear end of the cargo box, in order to prevent the gas at the rear of the cargo box from hindering the movement of the garbage, an exhaust hole is provided on the top of the cargo box, and the odor in the cargo box is discharged directly through the exhaust hole. However, the direct discharge of odor into the atmosphere will cause air pollution. In the application number 202410969557X previously filed by the applicant, entitled "Environmentally friendly loading method and domestic garbage loading system", a technical solution is disclosed that uses a garbage loading funnel and a sealing sleeve to guide domestic garbage into the cargo box and extract the odor from the garbage loading funnel for deodorization. This patent can ensure that the odor in the cargo box will not be directly discharged into the atmosphere during loading, which can avoid air pollution problems. However, how to allow the gas at the rear of the cargo box to smoothly enter and flow forward into the garbage loading funnel when the push plate of the compression mechanism pushes the garbage in the cargo box to move toward the rear end of the cargo box is a technical problem that needs to be solved. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a garbage truck cargo box system to solve the technical problem that the above-mentioned horizontal push-pull opening and closing sealing cover needs to slide on the rectangular elastic sealing ring during the opening and closing process, which in turn affects the service life of the rectangular elastic sealing ring; and to solve the technical problem that an exhaust hole is set on the top of the cargo box, and the odor in the cargo box is directly discharged into the atmosphere, causing air pollution.

[0006] The utility model relates to a cargo box system for a garbage transport truck, comprising a cargo box, a loading docking frame provided on the top of the cargo box, a garbage loading port located inside the loading docking frame, a sealing cover for sealing the garbage loading port, and a first linear actuator for driving the sealing cover to move in the front-rear direction of the cargo box.

[0007] The first linear drive is movably connected to the sealing cover in the vertical direction and fixedly connected in the horizontal direction;

[0008] A rectangular elastic sealing ring is provided on the top of the cargo box and is located outside the garbage loading port;

[0009] The top of the cargo box is also provided with a sliding support body for supporting the sealing cover during the sliding process of the sealing cover, a driving mechanism for driving the sliding support body to rise and fall, and a positioning guide structure for positioning and guiding the sliding support body to rise and fall. The sliding support body is located outside the rectangular elastic sealing ring;

[0010] When the sliding support body rises to the highest state, the sealing cover is pressed on the top surface of the sliding support body, and the top surface of the sliding support body is higher than the top surface of the rectangular elastic sealing ring; when the sliding support body descends to the lowest state, the sealing cover is pressed on the top surface of the rectangular elastic sealing ring, and the top surface of the sliding support body is lower than the top surface of the rectangular elastic sealing ring.

[0011] Furthermore, the driving mechanism is arranged on both sides of the sliding support body along the front-to-rear direction of the cargo box, and the driving mechanism includes a wedge block, a second linear drive that drives the wedge block to move along the front-to-rear direction of the cargo box, and an inclined surface arranged on the lower side of the end of the sliding support body to cooperate with the wedge block.

[0012] Furthermore, the positioning guide structure is a limiting strip arranged along the inner side surface and / or the outer side surface of the sliding support body.

[0013] Furthermore, a connecting hole is provided on the edge of the sealing cover, and a vertical insertion rod connected to the connecting hole is provided on the first linear actuator.

[0014] Furthermore, the front of the cargo box is provided with a push plate for pushing the garbage in the cargo box to the rear of the cargo box and a third linear drive for driving the push plate to move. A guide channel for guiding the gas at the rear of the cargo box to the garbage loading port is also provided under the top of the cargo box. The guide channel is composed of a guide plate with an air inlet hole or a guide pipe with an air inlet hole connected to the bottom of the top of the cargo box.

[0015] Furthermore, the garbage truck cargo box system also includes a sealing structure for closing the gap between the front end top of the sealing cover and the loading docking frame when the cover is open, and the sealing structure includes a front baffle fixed to the front end top of the sealing cover, a sealing strip fixed next to the baffle, and a rear baffle arranged at the top of the lateral insertion port of the loading docking frame.

[0016] Beneficial effects of the utility model:

[0017] 1. In this utility model, the garbage truck cargo box system slides horizontally on the top surface of the sliding support during opening and closing. The sealing cover does not contact the rectangular elastic sealing ring, thus avoiding frictional damage to the rectangular elastic sealing ring. When closing the sealing cover, the sealing cover slides horizontally into place and then withdraws, causing the sliding support to descend. Gravity then presses the sealing cover against the rectangular elastic sealing ring, sealing the garbage loading port and preventing odor from leaking and polluting the air during transportation.

[0018] 2. This utility model's garbage truck cargo box system features a diversion channel located below the top of the cargo box to direct the gas at the rear of the box toward the garbage loading port. As the push plate compresses the garbage, the gas at the rear of the box flows through the diversion channel toward the garbage loading port, preventing the gas from obstructing the movement of the garbage. The odor then enters the loading hopper connected to the garbage loading port, where it is extracted and deodorized by an exhaust device. This prevents the direct release of odor from the cargo box into the atmosphere, which could cause air pollution.

[0019] 3. The garbage truck cargo box system of the present invention can seal the gap between the front end top of the sealing cover and the loading docking frame when the cover is open, ensuring that during the loading process of the cargo box being docked with the garbage loading hopper, the odor in the cargo box will not escape into the atmosphere through the gap between the front end top of the sealing cover and the loading docking frame, further improving the environmental friendliness of the loading.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] In this embodiment, the garbage truck cargo box system includes a cargo box 1. The top of the cargo box is provided with a loading docking frame 2, a garbage loading port 3 located inside the loading docking frame, a sealing cover 4 for sealing the garbage loading port, and a first linear actuator 5 for driving the sealing cover in the forward and backward direction of the cargo box. A lateral insertion port for inserting the sealing cover is provided at the rear end of the loading docking frame. In this embodiment, the first linear actuator 5 can be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, a chain conveyor mechanism, or the like; in this embodiment, a hydraulic cylinder is used. The loading docking frame 2 is used to dock with the loading hopper that guides garbage into the cargo box during loading.

[0028] The first linear actuator is movably connected to the sealing cover in the vertical direction and fixedly connected in the horizontal direction. Specifically, in this embodiment, a connection hole 6 is provided on the edge of the sealing cover, and a vertical insertion rod 7 is provided on the telescopic rod of the hydraulic cylinder to connect to the connection hole. The vertical insertion rod 7 slides vertically with the connection hole 6 to achieve a connection mode in which the first linear actuator and the sealing cover are movably connected in the vertical direction and fixedly connected in the horizontal direction.

[0029] A rectangular elastic sealing ring 8 is fixedly provided on the top of the cargo box and is located outside the garbage loading port.

[0030] The top of the cargo box is also provided with a sliding support body 9 for supporting the sealing cover during the sliding process of the sealing cover, a driving mechanism for driving the sliding support body to move up and down, and a positioning guide structure for positioning and guiding the sliding support body to move up and down. The sliding support body is located on the outside of the rectangular elastic sealing ring and on the inside of the docking frame. In this embodiment, the sliding support body is a rectangular frame. Of course, in different embodiments, the sliding support body can also be four rectangular strip guide rails or two strip guide rails arranged along the length direction of the cargo box. In this embodiment, the driving mechanism is arranged on both sides of the sliding support body along the front-to-back direction of the cargo box. The driving mechanism includes a wedge block 10, a second linear drive 11 that drives the wedge block to move along the front-to-back direction of the cargo box, and an inclined surface 12 provided on the lower side of the end of the sliding support body to cooperate with the wedge block. The second linear drive 11 can be a cylinder, a hydraulic cylinder, an electric cylinder, etc. In this embodiment, a hydraulic cylinder is used. When the second linear actuator 11 pushes the wedge 10 to wedge under the inclined surface 12, the sliding support 9 is lifted upward by the wedge 10; when the second linear actuator 11 pulls the wedge 10 out from under the inclined surface 12, the sliding support 9 descends under the action of gravity. The positioning guide structure in this embodiment is a limit bar 13 arranged along the inner and outer sides of the sliding support. Of course, in different embodiments, the limit bar 13 can also be arranged only along the inner or outer side of the sliding support. The positioning guide structure can also be a limit pin that vertically penetrates the rectangular frame or the limit bar 13 and slides up and down with it.

[0031] When the sliding support body rises to the highest state, the sealing cover is pressed on the top surface of the sliding support body, and the top surface of the sliding support body is higher than the top surface of the rectangular elastic sealing ring; when the sliding support body descends to the lowest state, the sealing cover is pressed on the top surface of the rectangular elastic sealing ring, and the top surface of the sliding support body is lower than the top surface of the rectangular elastic sealing ring.

[0032] In the garbage transport truck cargo box system of this embodiment, during the process of closing the sealing cover, the second linear drive 11 first pushes the wedge 10 to wedge under the inclined surface 12 to lift the sliding support body 9, and then the first linear drive drives the sealing cover 4 to slide forward. During the sliding process, the sealing cover 4 does not contact the rectangular elastic sealing ring and will not cause damage to the rectangular elastic sealing ring; after the sealing cover 4 slides into place, the second linear drive 11 pulls the wedge 10 out from under the inclined surface 12. At this time, the sealing cover 4 and the sliding support body 9 descend, and the sealing cover 4 is pressed on the rectangular elastic sealing ring under the action of gravity to achieve sealing of the garbage loading port 3.

[0033] As an improvement to the above embodiment, the front of the cargo box is provided with a push plate 14 for pushing the garbage in the cargo box toward the rear, and a third linear actuator 15 for driving the push plate. A diversion channel 16 is also provided below the top of the cargo box for directing the gas at the rear of the cargo box toward the garbage loading port. The diversion channel comprises a diversion plate 17 with an air inlet or a diversion pipe with an air inlet connected to the bottom of the cargo box. The push plate squeezes the garbage in the cargo box, increasing the garbage loading capacity. During the squeezing process, the gas at the rear of the cargo box flows through the diversion channel 16 toward the garbage loading port, thus preventing the gas at the rear of the cargo box from obstructing the movement of the garbage backward.

[0034] As an improvement to the above embodiment, the garbage truck cargo box system also includes a sealing structure for closing the gap between the top front end of the sealing cover and the loading docking frame when the cover is open, and the sealing structure includes a front baffle 18 fixed to the top front end of the sealing cover, a sealing strip 19 fixed next to the baffle and a rear baffle 20 arranged at the top of the lateral insertion port of the loading docking frame.

[0035] In the garbage truck cargo box system of this embodiment, during the opening process, the driving mechanism first drives the sliding support body to move up and lift the sealing cover, and then the first linear drive drives the sealing cover to slide and open the garbage loading port. After the sealing cover is opened into place, the sealing strip is pressed between the front stop bar and the rear stop bar, thereby closing the gap between the front end top of the sealing cover and the loading docking frame.

[0036] 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.
