The input end of the power take-off structure is connected to the gearbox of the garbage truck chassis, and its output end is connected to the power actuator to fully utilize the engine of the garbage truck chassis to provide power to the linkage structure. Two sets of linkage structures are provided, respectively located on the left and right sides of the tailgate 12. Each set of linkage structures includes a power actuator, a power actuator support 32, a main drive linkage 33, a secondary drive linkage 34, and four sets of linkage supports. The power actuator support 32 is located on the side of the tailgate 12, and the tail end of the power actuator is fixed to the side of the tailgate 12 via the power actuator support 32. Its output end is axially connected to the middle section of the main drive linkage 33 at a position biased towards the sealing cover door 21. The four sets of linkage supports include two sets of tailgate linkage supports 35 and two sets of cover door linkage supports 36. Tailgate linkage supports 35 are arranged vertically on the side of the tailgate 12 and are all located below the power actuator support 32. Two sets of door shielding linkage supports 36 are arranged vertically on the side of the sealing door 21, and the distance between the two sets of tailgate linkage supports 35 is the same as the distance between the two sets of door shielding linkage supports 36. The main drive linkage 33 and the auxiliary drive linkage 34 are parallel to each other.

[0026] The leachate collecting assembly comprises a liquid guide plate 41, a liquid receiving box 42, a liquid guide pipe 45 and a contaminated liquid tank 46; the liquid guide plate 41 is arranged below the sealing shielding door 21, and the front end thereof is connected with the bottom end of the sealing shielding door 21, and the tail end thereof extends inwardly at an angle to the tail door 12; the liquid receiving box is fixed below the tail door 12, and water blocking side walls 43 are arranged on three sides of the liquid receiving box except the side far away from the garbage transfer vehicle compartment 1; a liquid outlet 44 is arranged on the water blocking side wall 43 of the liquid receiving box 42 close to the garbage transfer vehicle compartment 1, and the end of the liquid receiving box close to the garbage transfer vehicle compartment 1 is lower than the end thereof far away from the garbage transfer vehicle compartment 1 in the vertical direction; the liquid guide pipe 45 is connected between the liquid receiving box 42 and the contaminated liquid tank 46 through the liquid outlet 44, and the contaminated liquid tank 46 is arranged below the garbage transfer vehicle compartment 1 and used for temporarily storing leachate.

[0027] In the embodiment, when the garbage transfer vehicle is filled with municipal solid waste, the sealing shielding door 21 is opened, the power take-off structure drives the output end of the oil cylinder 31 to push out outwardly by taking power from the engine of the garbage transfer vehicle chassis, drives the first end of the main transmission connecting rod 33 to rotate clockwise around the connecting shaft of the tail door connecting rod support 35 which is above, drives the first end of the auxiliary transmission connecting rod 34 to rotate clockwise around the connecting shaft of the tail door connecting rod support 35 which is below, and finally drives the sealing shielding door 21 to rotate downwardly and enter the bottom of the tail door 12, exposes the tail door 12 of the garbage transfer vehicle and the inlet thereof below, and ensures seamless connection between the compressor in the garbage transfer station and the inlet.

[0028] When the garbage transfer vehicle carries municipal solid waste, the sealing cover door 21 is closed, the power take-off structure drives the output end of the oil cylinder 31 to retract inward from the engine of the garbage transfer vehicle chassis, pulls the first end of the main transmission connecting rod 33 to rotate counterclockwise around the connecting shaft of the tail door connecting rod support 35 which is relatively above, drives the first end of the auxiliary transmission connecting rod 34 to rotate counterclockwise around the connecting shaft of the tail door connecting rod support 35 which is relatively below, and finally drives the sealing cover door 21 to rotate upward and completely cover the outside of the tail door 12, so as to block the garbage between the inlet and the tail door 12 and the plug door 11. At this time, the oil cylinder 31 applies sufficient torque to the sealing cover door 21 to ensure sufficient pressure to compress the annular sealing rubber strip 29 between the tail door 12 and the sealing cover door 21, so that the annular sealing rubber strip 29 is deformed under the action of pressure, the cross section of the annular sealing rubber strip 29 is oval, and the gap between the tail door 12 and the sealing cover door 21 is completely filled to ensure that the gap between the tail door 12 and the sealing cover door 21 can be precisely sealed every time, so that the leachate in the vehicle compartment 1 cannot penetrate the compressed elastic sealing element 24, and sewage leakage is prevented.

[0029] At the same time, in order to deal with the special cases of carrying municipal solid waste, the water content of municipal solid waste is too large, or the elastic sealing element 24 is damaged by sharp objects in the transportation process, after the leachate penetrates the elastic sealing element 24, the inwardly inclined liquid guide plate 41 guides the leachate into the liquid receiving box 42, and the leachate in the liquid receiving box 42 is collected to one end near the garbage transfer vehicle compartment 1, and enters the liquid guide pipe 45 through the drainage port 44 on the water retaining side wall 43, and finally flows into the sewage tank 46. Under the guidance of the leachate collecting assembly, the leachate is collected in time and will not be splashed and dripped due to the bumping of the vehicle during transportation, so as to avoid the dripping of sewage during transportation.

[0030] In the embodiment, the above is only an example and does not limit the protection scope of the application.
