Description

Technical Field

[0001] The invention relates to the technical field of domestic garbage transport vehicles, and 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] In order to solve the problem of the horizontal push-pull sealing cover on the cargo box of the existing domestic garbage transport vehicle being not tightly sealed, the applicant first submitted an invention patent with application number 2024226413692 and the name of "Garbage Transport Vehicle Cargo Box Loading Port Sealing Device". This patent uses the inclined surface structure set on the rectangular inner cover and the rectangular frame opening to achieve the tight fit between the rectangular inner cover and the rectangular elastic sealing ring, ensuring the sealing effect. However, during the opening and closing process, the rectangular inner cover in this technical solution needs to slide one end of the rectangular elastic sealing ring, which will cause friction and wear on the rectangular elastic sealing ring, which will affect the service life of the rectangular elastic sealing ring.

[0004] In addition, in the existing cargo box with garbage compression function, in the process of the push plate of the compression mechanism pushing the garbage in the cargo box to move to the rear end of the cargo box, in order to avoid the gas behind the cargo box 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 directly discharged through the exhaust hole. However, the direct discharge of odor into the atmosphere will cause air pollution. In the application number 202410969557X previously proposed by the applicant, the name is "Environmentally friendly loading method and domestic garbage loading system for domestic garbage", which discloses a technical solution of using a garbage loading funnel and a sealing spacer to introduce domestic garbage into the cargo box and extracting 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 make the gas at the rear of the cargo box 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 to the rear end of the cargo box is a technical problem that needs to be solved. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a garbage transport truck cargo box system to solve the technical problem that the above-mentioned horizontal push-pull opening and closing type sealing cover needs to slide on the rectangular elastic sealing ring during the opening and closing process, which will affect 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 garbage transport truck cargo box system of the present invention comprises a cargo box, wherein the top of the cargo box is provided with a loading docking frame, a garbage loading port located inside the loading docking frame, a sealing cover for sealing the garbage loading port, and a first linear driver for driving the sealing cover to move along 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 the rectangular elastic sealing ring 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 and guiding structure for positioning and guiding the sliding support body to rise and fall, and 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 a sloped surface that is arranged on the lower side of the end of the sliding support body and cooperates 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, a push plate for pushing the garbage in the cargo box toward the rear of the cargo box and a third linear drive for driving the push plate to move are provided at the front of the cargo box, and a guide channel for guiding the gas at the rear of the cargo box to the garbage loading port is also provided below the top of the cargo box, and the guide channel is composed of a guide plate with an air inlet hole or a guide pipe with an air inlet hole connected below the top of the cargo box.

[0015] Furthermore, the garbage transport 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] The method for sealing the open cover seam of the cargo box system of a garbage transport vehicle described in the present invention comprises: during the cover opening process, a driving mechanism first drives a sliding support body to move upward to lift the sealing cover, and then a first linear drive drives the sealing cover to slide and open the garbage loading port. After the sealing cover is opened in place, the sealing strip is pressed between the front stop strip and the rear stop strip, thereby sealing the gap between the front end top of the sealing cover and the loading docking frame.

[0017] Beneficial effects of the present invention:

[0018] 1. In the garbage transport truck cargo box system of the present invention, during the process of opening or closing the sealing cover, the sealing cover slides horizontally on the top surface of the sliding support body, and the sealing cover does not contact the rectangular elastic sealing ring, thereby avoiding the problem of friction damage to the rectangular elastic sealing ring. When closing the sealing cover, after the sealing cover slides horizontally into place, it is withdrawn to make the sliding support body descend, and the sealing cover is pressed against the rectangular elastic sealing ring under the action of gravity, thereby achieving the sealing of the garbage loading port, which can avoid the problem of odor leakage and air pollution during transportation.

[0019] 2. The cargo box system of the garbage transport truck of the present invention provides a guide channel under the top of the cargo box to guide the gas at the rear of the cargo box to the garbage loading port. When the push plate compresses the domestic garbage backward, the gas at the rear of the cargo box flows to the garbage loading port through the guide channel, which can avoid the problem that the gas at the rear of the cargo box hinders the garbage from moving backward. The odor then enters the loading hopper connected to the garbage loading port, and the odor in the loading hopper is then extracted and deodorized by the exhaust device, thereby avoiding the technical problem that the odor in the cargo box is directly discharged into the atmosphere to cause air pollution.

[0020] 3. The garbage truck cargo box system and the method for sealing the open cover seam 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, and can ensure that during the loading process when the cargo box is 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, thereby further improving the environmental protection of the loading.

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] In this embodiment, the garbage transport 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 driver 5 for driving the sealing cover to move along the front and rear direction of the cargo box, and the rear end of the loading docking frame is provided with a lateral insertion port for inserting the sealing cover. In this embodiment, the first linear driver 5 can be a cylinder, a hydraulic cylinder, an electric cylinder, a chain conveying mechanism, etc., and a hydraulic cylinder is used in this embodiment. The loading docking frame 2 is used to dock with a loading funnel that guides garbage into the cargo box when loading garbage.

[0029] 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 connected to the connection hole is provided on the telescopic rod of the hydraulic cylinder. The vertical insertion rod 7 and the connection hole 6 are slidably matched to realize the 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.

[0030] A rectangular elastic sealing ring 8 is fixedly arranged on the top of the cargo box, and the rectangular elastic sealing ring is located outside the garbage loading port.

[0031] 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 lifting and guiding the sliding support body. 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 strip guides distributed in a rectangular shape or two strip guides 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 for driving the wedge block to move along the front-to-back direction of the cargo box, and an inclined surface 12 arranged on the lower side of the end of the sliding support body and cooperating 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 drive 11 pushes the wedge block 10 to wedge under the inclined surface 12, the sliding support body 9 is lifted upward by the wedge block 10; when the second linear drive 11 pulls the wedge block 10 out from under the inclined surface 12, the sliding support body 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 body. Of course, in different embodiments, the limit bar 13 can also be arranged only along the inner or outer side of the sliding support body; the positioning guide structure can also be a limit pin that vertically passes through the rectangular frame or the limit bar 13 and slides up and down with it.

[0032] 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.

[0033] In the garbage transport truck cargo box system of the present embodiment, during the process of closing the sealing cover, the second linear drive 11 first pushes the wedge block 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 the rectangular elastic sealing ring will not be damaged; after the sealing cover 4 slides into place, the second linear drive 11 pulls the wedge block 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.

[0034] As an improvement to the above embodiment, the front part of the cargo box is provided with a push plate 14 for pushing the garbage in the cargo box to the rear part of the cargo box and a third linear drive 15 for driving the push plate to move. A guide channel 16 for guiding the gas in the rear part of the cargo box to the garbage loading port is also provided under the top of the cargo box. The guide channel is formed by connecting a guide plate 17 with an air inlet or a guide pipe with an air inlet under the top of the cargo box. By squeezing the domestic garbage in the cargo box with the push plate, the loading amount of the garbage can be increased. During the squeezing process, the gas in the rear part of the cargo box flows to the garbage loading port through the guide channel 16, which can avoid the problem that the gas in the rear part of the cargo box hinders the garbage from moving backward.

[0035] As an improvement to the above-mentioned embodiment, the garbage truck cargo box system also includes a sealing structure for closing the gap between the top of the 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 of the 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.

[0036] The method for sealing the open lid seam of the cargo box system of a garbage transport truck in this embodiment includes: during the lid opening process, the driving mechanism first drives the sliding support body to move upward to 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 sealing the gap between the front end top of the sealing cover and the loading docking frame.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
