Description

Technical Field

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

[0002] A garbage loading port is set on the top of the cargo box of the domestic garbage transport truck. When loading at the garbage transfer station, the front garbage collection truck dumps the collected garbage into the garbage loading funnel. The lower end of the garbage loading funnel is sealed and docked with the garbage loading port on the top of the closed cargo box system for loading domestic garbage. The domestic garbage enters the cargo box of the domestic garbage transport truck under the guidance of the garbage loading funnel. After the domestic garbage is loaded, the sealing cover on the top of the closed cargo box system for loading domestic garbage needs to be closed to prevent the odor in the cargo box from spreading outward.

[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 a certain distance on the rectangular elastic sealing ring, which will cause friction and wear on the rectangular elastic sealing ring during the sliding process, which will affect the service life of the rectangular elastic sealing ring.

[0004] In addition, in order to solve the aforementioned garbage loading port sealing problem, the inventor filed a Chinese invention patent application with application number "202411771639X" and name "Garbage Transport Truck Cargo Box System and Opening Seam Sealing Method". In this invention technology, the sealing cover needs to slide back and forth on the sliding support body when opening and closing the sealing cover, and the sliding resistance is large, which may generate 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.

[0005] In view of the fact that the technology proposed in the aforementioned patent application still needs to be improved, the inventor conducted further technical improvement research and developed a new opening and closing cover sealing technology to solve the sealing technical problems of the opening and closing covers of the cargo box of domestic waste transport vehicles and the technical problems of the aforementioned patent technology such as 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.

[0042] 2. The cargo box system and loading method for enclosed loading of domestic garbage of the present invention, when closing the sealing cover, the sealing cover is first moved forward under the push of the first linear drive, and after moving forward to the right position, the running wheels on the sealing cover are just on the C-shaped groove block, and then the lifting drive drives the C-shaped groove block to descend, so that the sealing cover is pressed against the rectangular sealing ring around the garbage loading port, and the lifting drive drives the C-shaped groove block to descend and also presses and fixes the sealing cover; in this way, during the driving of the garbage transport vehicle, the position of the sealing cover is pressed and fixed by the C-shaped groove block and cannot move, and the sealing cover and the rectangular sealing ring are closely matched to ensure the sealing effect, effectively preventing the problem of odor in the cargo box from escaping; at the same time, it can also avoid the problem of garbage bouncing out of the cargo box during transportation.

[0043] 3. The cargo box system and loading method for enclosed loading of domestic waste of the present invention can protect the sealing ring by bearing the pressure of the sealing cover and the upper pressure block on the sealing cover through the limiting structure and limiting the deformation of the sealing ring. Moreover, the limiting structure can ensure that the sealing cover is reliably fixed under the strong pressure applied by the lifting drive to the sealing cover, and the sealing cover will not loosen during transportation.

[0044] 4. The cargo box system and loading method for enclosed loading of domestic waste of the present invention, when the sealing cover is opened to load domestic waste, the garbage loading funnel arranged in the domestic waste transfer workshop is pressed on the sealing ring on the top of the loading docking frame, so that a good seal is formed between the garbage loading funnel and the loading docking frame. This can prevent odor from escaping from the docking portion between the garbage loading funnel and the loading docking frame during loading, and can significantly improve the environmental friendliness of domestic waste transfer loading.

[0045] 5. The cargo box system for enclosed loading of domestic waste of the present invention adopts a sprocket chain transmission mechanism which does not occupy the movement space of the sealing cover, so that it is suitable for being arranged on both cargo boxes of longer lengths and cargo boxes of shorter lengths, and has stronger applicability.

[0046] 6. In the loading method of the cargo box system for enclosed loading of domestic waste of the present invention, the loading area located behind the garbage loading port of the cargo box adopts a compression loading method, which can increase the loading capacity of the cargo box; the loading area opposite to the garbage loading port is not compressed, which can prevent the garbage from flipping over the pressure plate and falling into the area in front of the pressure plate during squeezing.

[0047] 7. The container system and loading method for enclosed loading of domestic garbage of the present invention are provided with a shielding shell on the inner side of the loading docking frame to prevent garbage from falling onto the rectangular sealing ring and the walkway. Garbage is of various types and complex in composition, and is easy to be scattered and splashed.

[0072] The closed cargo box system for loading domestic waste also includes a first linear actuator for driving the sealing cover to move in the front-rear direction of the cargo box, and 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 first linear actuator is a hydraulic cylinder 8, and the connecting piece includes a crossbar 9 connected to the hydraulic cylinder and a vertical connecting rod 10 arranged on the crossbar, and the edge of the sealing cover is provided with a collar 11 that is slidably matched with the vertical connecting rod up and down.

[0073] The domestic garbage transport vehicle opening and closing cover sealing system also includes a lifting drive 12 and a lifting block 131 and a hook 132 driven by the lifting drive. The hook is composed of a pressure plate 1321 and a side plate 1322 connected. The side plate 1322 is connected to the lifting block 131 to form a lifting module 13 with a C-shaped groove. The lifting block is located at the gap. The lifting block is used to support the walking wheel. The hook is used to fix the sealing cover in the closed state. In this embodiment, the lifting drive 12 is a hydraulic cylinder with a piston rod arranged vertically upward, and the cylinder body of the hydraulic cylinder is arranged on the side wall of the cargo box below the walking path 6; of course, in different embodiments, the piston rod of the lifting drive 12 can also be arranged vertically downward, and the cylinder body of the hydraulic cylinder can be arranged on the side wall of the cargo box above the walking path 6 or on the loading docking frame 3, and the piston rod of the lifting drive 12 is correspondingly connected to the hook 132. The lifting drive 12 can also be in other forms such as an electric cylinder or a cylinder.

[0074] The sealing system of the opening and closing cover of the domestic garbage transport vehicle further comprises a rectangular sealing ring 14 arranged at the edge of the garbage loading port. Of course, in different embodiments, the rectangular sealing ring 14 can also be arranged on the bottom surface of the sealing cover.

[0075] The opening and closing process of the cargo box system for enclosed loading of domestic waste in this embodiment is as follows:

[0076] Opening process: First, the lifting driver 12 drives the lifting module 13 to move upward in the gap 7. During this process, the lifting module 13 lifts the running wheel 5 and the sealing cover 4 connected to the running wheel and moves upward together; during the upward movement of the sealing cover 4, the collar 11 connected to the sealing cover 4 slides upward on the vertical connecting rod 10. When the lifting block 131 moves up to be flush with the walking path 6, the lifting driver 12 stops working. Then, the hydraulic cylinder 8 works, and the piston rod of the hydraulic cylinder 8 contracts to pull the sealing cover 4 backward, thereby realizing the opening of the sealing cover.

[0077] Closing process: First, the hydraulic cylinder 8 works, and the piston rod of the hydraulic cylinder 8 extends to push the sealing cover 4 forward. When the sealing cover 4 moves forward to the point where the running wheel on its side is in the lifting module 13, the hydraulic cylinder 8 stops working. Then, the lifting drive 12 starts to drive the lifting module 13 to move downward in the gap 7. During this process, the lifting module 13 lifts the running wheel 5 and the sealing cover 4 connected to the running wheel and moves downward together; during the downward movement of the sealing cover 4, the collar 11 connected to the sealing cover 4 slides downward on the vertical connecting rod 10; when the sealing cover 4 moves down to the point where it contacts the rectangular sealing ring 14, the sealing cover 4 begins to apply pressure to the rectangular sealing ring 14, and the rectangular sealing ring 14 begins to deform elastically under pressure, and the deformation of the rectangular sealing ring 14 is controlled by the downward movement distance of the sealing cover 4. In a specific implementation, the downward movement distance of the sealing cover 4 can be controlled by controlling the stroke of the lifting drive 12, or a limit structure can be set to limit the downward movement distance of the sealing cover 4. In this way, when the cover is closed, the rectangular sealing ring 14 is used to seal the gap between the edge of the garbage loading port 2 and the sealing cover 4, which can prevent the problem of odor in the cargo box from escaping.

[0078] As an improvement to the first embodiment, support wheels 91 are provided at both ends of the cross bar. The cross bar 9 is supported by the support wheels 91, and the piston rod of the hydraulic cylinder 8 can be supported, thereby protecting the hydraulic cylinder 8.

[0079] Embodiment 2: Figure 8-Figure 18 As shown, the cargo box system for enclosed loading of domestic waste in this embodiment includes 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.

[0080] The closed cargo box system for loading domestic garbage also includes a sealing cover 4 for sealing the garbage loading port, the edges of the sealing cover are provided with running wheels 5, and the top of the cargo box outside the garbage loading port is formed with a walking path 6 that cooperates with the running wheels, and the walking path is provided with notches 7 equal to the number of the running wheels, and the notches are passage openings for the running wheels to move downward when the cover is closed. The front side (i.e., the side facing the front of the vehicle), the left side and the right side of the loading docking frame 3 are sealedly connected to the cargo box; a passage for the sealing cover 4 to pass through is formed between the rear side of the loading docking frame 3 and the top of the cargo box.

[0081] The closed cargo box system for loading domestic waste also includes a first linear driver for driving the sealing cover to move along the front-rear direction of the cargo box, the first linear driver 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 first linear driver is a sprocket chain transmission mechanism, and the sprocket chain transmission mechanism includes a front support 15 arranged on the rear side of the loading docking frame, a front sprocket 16 arranged on the front support, a rear support 17 arranged on the rear part of the top surface of the cargo box, a rear sprocket 18 arranged on the rear support, a power device 19 for driving the rear sprocket to rotate, and a chain 20 connecting the front sprocket and the rear sprocket.

[0082] The connecting member is arranged on the chain, and a vertical groove 25 is arranged on the connecting member. The edge of the sealing cover is provided with a connecting plate 23, and a horizontal pin 24 is provided on the connecting plate to slide up and down with the vertical groove. In this embodiment, the connecting member is composed of a transmission module 21 consisting of a rack 211 meshed with the chain, a transmission plate 212 fixed on one side or both sides of the rack, a horizontal bar 213 fixed on the transmission plate to support the chain, and a slider 214 connected to the transmission plate, and the vertical groove 25 is arranged on the transmission plate; the edge of the cargo box is also provided with a guide rod 22 arranged parallel to the length direction of the cargo box, and the slider 214 is arranged on the guide rod 22 and slides with the guide rod. In this embodiment, the horizontal bar 213 can prevent the chain 20 from separating from the rack 211; through the sliding cooperation between the slider 214 and the guide rod 22, the weight of the transmission module 21 is borne by the guide rod while guiding the translation, and the chain 20 does not bear the gravity of the transmission module, which is conducive to protecting the chain. In this embodiment, the power device 19 includes a motor 191 and a reducer 192. The power output by the motor 191 is transmitted to the axle of the rear sprocket 18 via the reducer 192. In this embodiment, the reducer 192 adopts a sprocket chain reduction transmission structure in which a small sprocket drives a large sprocket (the chain is not drawn in the figure). Of course, the reducer 192 can also adopt a gear reduction transmission structure in which a small gear drives a large gear.

[0083] The sealing system for the opening and closing cover of the domestic garbage transport vehicle also includes a lifting drive 12 and a lifting block 131 and a hook 132 driven by the lifting drive. The hook is composed of a pressure plate 1321 and a side plate 1322 connected. The side plate 1322 is connected to the lifting block 131 to form a lifting module 13 with a C-shaped groove. The lifting block is located at the gap. The lifting block is used to support the walking wheel. The hook is used to fix the sealing cover in the closed state. In this embodiment, the lifting drive 12 is a hydraulic cylinder with a piston rod arranged vertically downward. The piston rod is connected to the hook 132. The cylinder body of the hydraulic cylinder is arranged on the side wall of the cargo box above the walking path 6 or / and the loading docking frame 3. Of course, in different embodiments, the piston rod of the hydraulic cylinder can also be arranged vertically upward. At this time, the cylinder body of the hydraulic cylinder is arranged on the side wall of the cargo box below the walking path 6, and the piston rod of the hydraulic cylinder is connected to the lifting block 131.

[0084] The sealing system of the opening and closing cover of the domestic garbage transport vehicle further comprises a rectangular sealing ring 14 arranged at the edge of the garbage loading port.

[0085] The opening and closing process of the cargo box system for enclosed loading of domestic waste in this embodiment is as follows:

[0086] Opening process: First, the lifting driver 12 drives the lifting module 13 to move upward in the gap 7. During this process, the lifting module 13 lifts the running wheel 5 and the sealing cover 4 connected to the running wheel and moves upward together; during the upward movement of the sealing cover 4, the cross pin 24 slides upward in the vertical groove 25. When the lifting block 131 moves up to be flush with the walking path 6, the lifting driver 12 stops working. Then, the power device 19 works, and the power output by the motor 191 is transmitted to the rear sprocket 18 through the reducer 192. The rear sprocket 18 drives the chain 20 to move, and the chain 20 drives the transmission module 21 to move toward the rear end of the cargo box. The transmission module 21 drives the sealing cover 4 to move toward the rear end of the cargo box through the cross pin 24 and the connecting plate 23, thereby realizing the opening of the sealing cover.

[0087] Closing process: First, the motor 191 of the power device 19 works, and the rotation direction of the motor 191 is opposite to that of the opening process. The power output by the motor 191 is transmitted to the rear sprocket 18 through the reducer 192, and the rear sprocket 18 drives the chain 20 to move, and the chain 20 drives the transmission module 21 to move toward the front end of the cargo box. The transmission module 21 drives the sealing cover 4 to move toward the front end of the cargo box through the cross pin 24 and the connecting plate 23. When the sealing cover 4 moves to the side of the running wheel 5 in the lifting module 13, the motor 191 stops working. Then, the lifting drive 12 starts to drive the lifting module 13 to move downward in the gap 7. During this process, the lifting module 13 lifts the running wheel 5 and the sealing cover 4 connected to the running wheel and moves downward together; during the downward movement of the sealing cover 4, the cross pin 24 slides downward in the vertical slot 25. When the sealing cover 4 moves down to contact the rectangular sealing ring 14, the sealing cover 4 begins to exert pressure on the rectangular sealing ring 14, and the rectangular sealing ring 14 begins to deform elastically under pressure, and the deformation of the rectangular sealing ring 14 is controlled by the downward movement distance of the sealing cover 4. In a specific implementation, the downward movement distance of the sealing cover 4 can be controlled by controlling the stroke of the lifting driver 12, or a limit structure can be set to limit the downward movement distance of the sealing cover 4. In this way, when the cover is closed, the gap between the edge of the garbage loading port 2 and the sealing cover 4 is sealed by the rectangular sealing ring 14, which can prevent the odor in the cargo box from escaping.

[0088] As an improvement to the above two embodiments, the closed cargo box system for loading domestic waste further includes a limiting structure 26 arranged beside the sealing ring for limiting the downward movement distance of the sealing cover, and the top of the limiting structure is lower than the top of the sealing ring 14. In this improvement, the limiting structure is a rectangular frame arranged outside the sealing ring. Of course, the limiting structure 26 can also be in other forms, such as the limiting structure 26 can be a pad arranged along the periphery of the sealing ring 14. The limiting structure 26 bears the pressure of the sealing cover 4 and the hook 132, and limits the deformation of the sealing ring 14, which can protect the sealing ring 14 and reliably fix the sealing cover.

[0089] As a further improvement to the above embodiment, a sealing ring 27 is provided on the top surface of the loading docking frame. When the sealing cover 4 is opened to load domestic waste, the lower end of the garbage loading hopper arranged in the domestic waste transfer workshop is pressed on the sealing ring 27 on the top of the loading docking frame, so that a good seal is formed between the garbage loading hopper and the loading docking frame, thereby preventing odor from escaping from the docking portion between the garbage loading hopper and the loading docking frame during the loading process, and significantly improving the environmental protection of domestic waste transfer loading.

[0090] As a further improvement to the above embodiment, the top surface of the sealing cover is a smooth plane, and the bottom of the rear side of the loading docking frame is provided with an upper sealing strip 28 that cooperates with the top surface of the sealing cover in the open state. The seam between the bottom of the rear side of the loading docking frame and the top surface of the sealing cover 4 is sealed. In this improvement, the upper sealing strip 28 is provided to contact and seal with the top surface of the sealing cover 4, so that when the cover is opened to load garbage, it can prevent odor from escaping from the seam, thereby improving the environmental protection of loading.

[0091] As a further improvement to the above embodiment, the bottom surface of the sealing cover is a smooth plane, and a lower sealing strip 29 is provided beside the rear side edge of the garbage loading port, which cooperates with the bottom surface of the sealing cover in the open state. In the open state, the bottom surface of the sealing cover 4 leaves the rectangular sealing ring 14, and there is a gap between the bottom surface of the sealing cover and the rectangular sealing ring 14; the improvement can prevent odor from escaping from the gap by providing the lower sealing strip 29 to seal with the bottom surface of the sealing cover, thereby improving the environmental protection of the loading.

[0092] Since the top and bottom surfaces of the sealing cover 4 in the above improvement are smooth planes, the sealing cover 4 can fully contact with the upper sealing strip 28 and the lower sealing strip 29, and the gap between the sealing cover 4 and the upper sealing strip 28 and the lower sealing strip 29 is reduced, thereby improving the environmental protection of loading. In addition, the top and bottom surfaces of the sealing cover 4 are smooth planes, so that when the cover is opened, the sliding friction resistance between the sealing cover 4 and the upper sealing strip 28 and the lower sealing strip 29 is small, which can reduce the friction and wear on the upper sealing strip 28 and the lower sealing strip 29, and is conducive to extending the service life of the device.

[0096] As a further improvement to the above embodiment, a heating device 33 is provided on the sealing cover. When operating in a low-temperature cold environment, ice may form on the sealing cover 4. Ice on the surface of the sealing cover will affect its forward and backward movement. In this improvement, a heating device 33 is provided in the sealing cover. The heating device 33 can be an electric heating tube. The heating device 33 heats and melts the ice on the surface of the sealing cover, thereby ensuring reliable operation in low-temperature cold weather.

[0097] As a further improvement to the above embodiment, the closed cargo box system for loading domestic waste also includes a pushing device for pushing the domestic waste in the cargo box from front to back, the pushing device includes a pressing plate 34 and a second linear driver 35 for driving the pressing plate, the second linear driver can be a hydraulic cylinder, an electric cylinder, etc., the edge of the pressing plate 34 is slidably matched with the inner wall of the cargo box, and the second linear driver 35 is arranged parallel to the length direction of the cargo box. In this embodiment, the second linear driver 35 adopts a multi-stage hydraulic cylinder; in a specific implementation, the cylinder body of the hydraulic cylinder can be fixed on the pressing plate, the end of the piston rod of the hydraulic cylinder is connected to the front of the cargo box, and a protective shell 36 can be provided on the outside of the hydraulic cylinder to protect it; or the end of the piston rod of the hydraulic cylinder is fixed on the pressing plate, and the cylinder body of the hydraulic cylinder is connected to the front of the cargo box or on a bracket provided in the cargo box.

[0098] The loading method of the cargo box system for enclosed loading of domestic waste in the above embodiments comprises the following steps:

[0099] 1) Move the cargo box to the bottom of the garbage loading hopper in the domestic waste transfer workshop.

[0100] 2) The garbage loading hopper moves down and seals with the loading docking frame. In the docking state, the sealing ring 27 is compressed, and the sealing ring 27 seals the gap between the garbage loading hopper and the loading docking frame, and then the sealing cover is opened.

[0101] 3) The front-end garbage collection truck pours the domestic garbage into the garbage loading funnel.

[0102] 4) The pushing device pushes the domestic waste entering the cargo box toward the back half of the cargo box.

[0103] 5) Repeat steps 3) and 4) to load the domestic garbage into the area behind the garbage loading port in the cargo box.

[0104] 6) Repeat step 3) to load the household waste into the remaining area of ​​the cargo box without pushing.

[0105] 7) Close the sealing cover.

[0106] In the loading method of the cargo box system for enclosed loading of domestic waste in the present embodiment, the loading area located behind the garbage loading port of the cargo box adopts a compression loading method, which can increase the loading capacity of the cargo box; the loading area opposite to the garbage loading port is not compressed, which can prevent the garbage from flipping over the pressure plate and falling into the area in front of the pressure plate during squeezing.

[0107] The second loading method of the cargo box system for enclosed loading of domestic waste described in the above embodiments comprises the following steps:

[0108] 1) Pour domestic garbage into the garbage loading port;

[0109] 2) The pushing device pushes the domestic garbage entering the cargo box toward the rear half of the cargo box;

[0110] 3) Repeat steps 1) and 2) to load the domestic garbage into the area behind the garbage loading port in the cargo box;

[0111] 4) Repeat step 1) to load the domestic waste into the remaining area of ​​the cargo box without pushing;

[0112] 5) Close the sealing cover.

[0113] The present method discloses a method for loading garbage in a closed cargo box system for domestic garbage without loading garbage in a domestic garbage transfer workshop. Since the first linear drive adopts a sprocket chain transmission mechanism, the cargo box can be miniaturized. The use of the miniaturized closed cargo box system for loading domestic garbage can be diversified. For example, it can be placed in old residential areas and communities with narrow roads to collect garbage. The side-mounted garbage loading mechanism can also be configured by itself. After the front-end domestic garbage collection vehicle is equipped with the cargo box system, it can collect garbage in the living community.

[0114] As an improvement to the above two loading methods, the loading method also includes monitoring the internal situation of the cargo box through a camera, so that the garbage loading is completed under visual monitoring. In this way, under the monitoring of the camera, the staff controlling the operation of the pushing device can intuitively understand the situation of the garbage device in the cargo box, so as to more accurately control the operation process of the pushing device, which is conducive to improving the safety of the operation.

[0115] 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.
