Description

Technical Field

[0001] The invention relates to the technical field of domestic garbage transport vehicles, and in particular to an opening and closing sealing system and a sealing method for a cargo box sealing cover 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.

[0005] In order to solve the above problems, the inventor filed a Chinese invention patent application with application number "202411771639X" and titled "Garbage Transport Truck Cargo Box System and Opening Seam Sealing Method". In this invention technology, when opening and closing the sealing cover, the sealing cover needs to slide back and forth on the sliding support body, which has a large sliding resistance and may produce a large noise; and the cargo box cover is pressed on the garbage loading port by its own gravity, and the sealing reliability needs to be improved. In response to this, the applicant has developed a new opening and closing cover sealing technology in further technical improvement research to solve the technical problems of the opening and closing cover sealing technology of the domestic garbage transport truck cargo box and the technical problems of the large sliding friction resistance of the sealing cover, the friction noise of the opening and closing cover, and the reliability of the sealing cover fixation in the above patent technology.

After the sealing cover moves forward to the right position, the traveling wheel is just on the lifting block. Then the lifting drive drives the lifting block to descend, so that the sealing cover is pressed on the garbage loading port. Then the lifting drive continues to descend to make the hook hook on the top of the sealing cover, so that the sealing cover is pressed and fixed, and the garbage loading port is tightly sealed by the sealing cover.

[0021] Furthermore, during the process of opening the cover, the lifting block is first driven up by the lifting drive to fill the gap on the walkway, and then the sealing cover is pulled backward by the first linear drive; when the sealing cover moves backward into place, the gap between the front bottom surface of the sealing cover and the top of the cargo box is closed by the transverse baffle, and the sealing strip is clamped by the front baffle and the rear baffle, thereby closing the gap between the front top surface of the sealing cover and the loading docking frame.

[0022] Beneficial effects of the present invention:

[0023] 1. The sealing system and sealing method of the opening and closing cover of the domestic waste transport vehicle of the present invention, when opening or closing the sealing cover, the sealing cover is translated on the top of the cargo box by rollers, the sealing cover has low movement resistance and low movement noise.

[0024] 2. The sealing system and sealing method of the opening and closing cover of the domestic garbage transport vehicle of the present invention, when closing the sealing cover, the sealing cover first moves forward under the push of the first linear drive, and after moving forward to the right position, the running wheel on the sealing cover is just on the lifting block, and then the lifting drive drives the lifting block to descend, so that the sealing cover is pressed against the garbage loading port, and the lifting drive continues to descend to make the hook hang and press on the top of the sealing cover. In this way, during the driving process of the garbage transport vehicle, the position of the sealing cover is reliably fixed by the hook, ensuring the reliability of the closure of the garbage loading port, and the odor in the cargo box cannot escape from the cargo box.

[0025] During the opening process, the lifting block is first driven by the lifting driver to rise, and the gap on the walking path is filled by the lifting block, and then the sealing cover is pulled backward by the first linear driver. When the sealing cover moves back to the right position, the gap between the front bottom surface of the sealing cover and the top of the cargo box is closed by the transverse baffle, and the gap between the front top surface of the sealing cover and the loading docking frame is closed by the sealing strip, so that when loading garbage, after the garbage loading hopper is docked with the loading docking frame on the cargo box, the odor in the cargo box can only enter the garbage loading hopper upward through the garbage loading port, and cannot escape from the gap between the front bottom surface of the sealing cover and the top of the cargo box, and the gap between the front top surface of the sealing cover and the loading docking frame. The odor entering the loading hopper will be sucked away by the exhaust device and sent to the deodorization device for deodorization, which prevents the odor from directly entering the atmosphere during the loading process, ensuring the environmental protection of domestic garbage loading.

[0026] 3. The sealing system of the lid of the domestic garbage transport vehicle 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 by the exhaust device and sent to the deodorization device for deodorization, thereby avoiding the technical problem that the odor in the cargo box is directly discharged into the atmosphere to cause air pollution.

[0035] In this embodiment, the sealing system of the opening and closing cover of the domestic garbage transport vehicle comprises a cargo box 1, a garbage loading port 2 is arranged on the top of the cargo box, and a loading docking frame 3 is arranged above the garbage loading port. The loading docking frame 3 is rectangular.

[0036] In this embodiment, the sealing system of the opening and closing cover of the domestic waste transport vehicle also includes a sealing cover 4 for sealing the garbage loading port 2 and a first linear actuator 5 for driving the sealing cover to move along the front and rear direction of the cargo box. The front of the cargo box is the side of the cargo box facing the front of the domestic waste transport vehicle; the first linear actuator 5 can be in the form of a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, a sprocket chain transmission mechanism, etc. In this embodiment, the first linear actuator 5 adopts a hydraulic cylinder. The first linear actuator is connected to the sealing cover through a connecting piece, and the connecting piece and the sealing cover are slidably matched in the height direction of the cargo box. In this embodiment, the connecting piece includes a cross bar 6 connected to the first linear actuator and a vertical connecting rod 7 arranged on the cross bar, and the edge of the sealing cover is provided with a collar 8 that is slidably matched with the vertical connecting rod up and down.

[0037] A walking wheel 9 is arranged on the lower side of the edge of the sealing cover, and the top of the cargo box outside the garbage loading port constitutes a walking path 10 cooperating with the walking wheel. The walking path is provided with notches 11 equal to the number of the walking wheels, and the notches are passage openings for the walking wheels to move downward when the cover is closed.

[0038] The domestic waste transport vehicle cover sealing system also includes a lifting driver 12 arranged on the side wall of the cargo box, a lifting block 13 and a hook 14 driven to lift by the lifting driver, and the lifting driver can be a hydraulic cylinder, a gas cylinder or an electric cylinder, etc. In this embodiment, a hydraulic cylinder is used; in this embodiment, the lifting block 13 is fixed on the piston rod of the hydraulic cylinder, and the hook 14 is fixed on the lifting block. The lifting block is located at the notch, and the lifting block is used to support the running wheel, and the hook is used to fix the sealing cover in the closed state.

[0039] The sealing system of the opening and closing cover of the domestic garbage transport vehicle further includes a rectangular sealing ring 19 arranged at the edge of the garbage loading port. Of course, in a specific implementation, the rectangular sealing ring can also be arranged on the bottom surface of the sealing cover. When the cover is closed, the cover seal is pressed on the rectangular sealing ring 19, which can better seal the garbage loading port and achieve a better sealing effect.

[0040] In the sealing system of the opening and closing cover of the domestic garbage transport vehicle in this embodiment, when closing the sealing cover, the sealing cover first moves forward under the push of the first linear drive, and after moving forward to the right position, the running wheel on the sealing cover is just on the lifting block, and then the lifting drive drives the lifting block to descend, so that the sealing cover is pressed against the rectangular sealing ring at the edge of the garbage loading port, and the lifting drive continues to descend to make the hook hang and press on the top of the sealing cover. In this way, during the driving process of the garbage transport vehicle, the position of the sealing cover is reliably fixed by the hook, ensuring the reliability of the closure of the garbage loading port, and the odor in the cargo box cannot escape from the cargo box.

[0041] As an improvement to the above-mentioned embodiment, the sealing system of the opening and closing cover of the domestic waste transport vehicle also includes a transverse baffle 15, which is arranged beside the rear side edge of the garbage loading port and is used to seal the gap between the front bottom surface of the sealing cover and the top of the cargo box when the cover is open.

[0042] As an improvement to the above embodiment, the sealing system of the opening and closing cover of the domestic waste transport vehicle further includes a sealing structure for closing the gap between the front top surface of the sealing cover and the loading docking frame in the open cover state, and the sealing structure includes a front baffle 16 fixed to the top of the front end of the sealing cover, a sealing strip 17 fixed beside the front baffle, and a rear baffle 18 arranged on the rear bottom surface of the loading docking frame. After the cover is opened in place, the sealing strip 17 is clamped between the front baffle 16 and the rear baffle 18, thereby sealing the gap between the front top surface of the sealing cover and the loading docking frame.

[0043] During the opening process, the lifting block is first driven by the lifting driver to rise, and the gap on the walking path is filled by the lifting block, and then the sealing cover is pulled backward by the first linear driver. When the sealing cover moves back to the right position, the gap between the front bottom surface of the sealing cover and the top of the cargo box is closed by the transverse baffle, and the gap between the front top surface of the sealing cover and the loading docking frame is closed by the sealing strip, so that when loading garbage, after the garbage loading hopper is docked with the loading docking frame on the cargo box, the odor in the cargo box can only enter the garbage loading hopper upward through the garbage loading port, and cannot escape from the gap between the front bottom surface of the sealing cover and the top of the cargo box, and the gap between the front top surface of the sealing cover and the loading docking frame. The odor entering the loading hopper will be sucked away by the exhaust device and sent to the deodorization device for deodorization, which prevents the odor from directly entering the atmosphere during the loading process, ensuring the environmental protection of domestic garbage loading.

[0044] As an improvement to the above embodiment, support wheels 20 are provided at both ends of the crossbar. The crossbar 6 is supported by the support wheels, thereby providing support to the first linear drive, thereby protecting the first linear drive.

[0045] As an improvement to the above embodiment, the front part of the cargo box is provided with a push plate 21 for pushing the garbage in the cargo box to the rear part of the cargo box and a second linear drive 22 for driving the push plate to move. In this embodiment, the second linear drive 22 adopts a multi-stage hydraulic cylinder; the top of the cargo box is also provided with a guide channel 23 for guiding the gas at the rear part of the cargo box to the garbage loading port. The guide channel is composed of a guide plate 24 with an air inlet connected to the bottom of the top of the cargo box. Of course, the guide plate 24 with an air inlet can also be replaced by a guide pipe with an air inlet. By squeezing the domestic garbage in the cargo box with the push plate, the loading capacity of the garbage can be increased. During the squeezing process, the gas at the rear part of the cargo box flows to the garbage loading port through the guide channel 23, which can avoid the problem that the gas at the rear part of the cargo box hinders the garbage from moving backward.

[0046] As an improvement to the above embodiment, a sealing pad 25 is arranged around the top surface of the loading docking frame 3. When loading domestic garbage, the loading funnel presses on the sealing pad 25 to dock with the loading docking frame 3, which can enhance the docking sealing effect between the loading funnel and the loading docking frame 3.

[0047] According to the sealing method of the sealing system of the opening and closing cover of the domestic garbage transport vehicle described in the above embodiment, it includes:

[0048] When closing the sealing cover, the sealing cover is first pushed forward by the first linear drive. After the sealing cover moves forward to the right position, the running wheel is just on the lifting block. Then the lifting drive drives the lifting block to descend, so that the sealing cover is pressed on the garbage loading port. Then the lifting drive continues to descend so that the hook is hooked on the top of the sealing cover, so that the sealing cover is pressed and fixed, and the garbage loading port is tightly pressed and sealed by the sealing cover. In the specific implementation, in order to further improve the sealing effect of closing the cover, a rectangular sealing ring 19 can also be set on the edge of the garbage loading port. Of course, the rectangular sealing ring can also be set on the bottom surface of the sealing cover. When closing the cover, the cover seal is pressed on the rectangular sealing ring 19, which can better close the garbage loading port and achieve a better sealing effect.

[0049] During the opening process, the lifting block is first driven up by the lifting driver to fill the gap on the walking path, and then the sealing cover is pulled backward by the first linear driver; when the sealing cover moves backward into place, the gap between the front bottom surface of the sealing cover and the top of the cargo box is closed by the transverse baffle, and the sealing strip is clamped by the front baffle and the rear baffle, so as to close the gap between the front top surface of the sealing cover and the loading docking frame.
