The air inlet channel 641 of the rear garbage can is provided with a negative pressure detection mechanism 66 which can detect the negative pressure in the rear garbage can 64.

Referring to fig. 8, the air flow direction is that the engine 11 drives the fan a14 to work, the air flow in the rear dustbin 64 enters the rear dustbin air inlet channel 641 through the rear dustbin filter screen 642, then enters the air inlet cavity of the fan a14, and finally is exhausted to the atmosphere through the air outlet of the fan a 14;

referring to fig. 10, the garbage moves in the direction that the garbage enters the rear suction duct 56 through the suction nozzle of the rear suction port 57 and enters the rear garbage can air inlet duct 645, a part of the garbage directly stays in the rear garbage can 64 under the action of gravity, and a part of the lighter garbage collides with the rear garbage can dome 643 to stay in the rear garbage can 64, and a part of the lighter garbage bypasses the rear garbage can dome 643 to continue to move along with the direction of the air flow. When the garbage enters the rear garbage can filter screen 642, most of the garbage is left in the rear garbage can 64, and very small garbage may pass through the rear garbage can filter screen 642, travel in the same direction as the air flow, and finally be discharged into the atmosphere through the air outlet of the fan A14.

The tail part of the front garbage can body 61 is provided with a front door body 617 which is sealed by a front door body sealing strip 616. The front door body 617 is opened and closed by a front garbage bin rear door oil cylinder 349; when the front door 617 is opened, the front garbage bin 61 is communicated with the rear garbage bin 64, and when the front door 617 is closed, the front garbage bin 61 is separated from the rear garbage bin 64 to form independent bins respectively. To prevent the impact of the garbage, the rear door cylinder 349 of the front garbage can is provided with a guard.

The tail of the rear garbage can body 64 is provided with a rear door body 647 which is sealed by a rear door body sealing strip 646. The rear door body 647 is opened and closed by the rear garbage bin rear door oil cylinder 340; when the rear door body 647 is opened and the front door body 617 is closed, only the rear garbage bin 64 is unloaded; when the rear door 647 and the front door 617 are both opened, the front and rear garbage boxes can be unloaded, and when the rear door 647 is closed, the boxes are not communicated with the outside.

The box swivel mount 69 is provided at the rear end of the box so that it can rotate around the sub-frame system 7;

the utility model also provides a sweeping method, this sweeping method uses foretell sweeping machine, and the sweeping method includes:

cleaning mode: the rotation of the sweeper can concentrate the garbage on the two sides of the curtain blocking mechanism 51, and the suction port is in the effective suction range. According to the cleaning requirement, one-side cleaning operation can be selected, for example, when the left operation is selected, the right sweeper does not work; when the right side is selected for operation, the left side sweeper does not work, the angle of each sweeper can be adjusted, and the sweeping operation of different pavements and different garbage can be met.

A dust fall mode: the water pump 23 is operated to provide water source for each spray head, so as to realize dust fall for work. According to different wastes, the water yield of each spray head can be controlled by a valve of the water separating body 21. And according to different working methods, different spray heads can be selected for spraying water.

A suction mode: when the amount of the road garbage is single, the front combined suction port 54 and the rear suction port 57 can work together, at the moment, the front door body 617 is opened, and the rear door body 647 is closed, so that the front garbage box body 61 and the rear garbage box body 64 form a whole, and the effective utilization rate of the box bodies is increased; it is also possible to work the rear suction opening 57 alone. When the rear suction port 57 works alone, the pressure oil of the hydraulic oil pump B36 is directly returned to the hydraulic oil tank assembly 32 through the hydraulic valve group B37.

When the pavement garbage needs to be classified, the front combined suction port 54 and the rear suction port 57 work simultaneously, and the front door body 617 and the rear door body 647 are both in a closed state. According to the condition of road surface garbage, the rotating speeds of a fan A14 and a fan B10 are intelligently adjusted, the type of garbage needing to be sucked into a front combined suction port 54 and a rear suction port 57 of the garbage is selected, a system can feed back to an ECU, the negative pressure value of the system is detected through respective negative pressure detection mechanisms, the opening degree of an electric control proportional valve on an engine 11 or a hydraulic valve set B37 is automatically adjusted, and the two boxes reach the set negative pressure value. The sewage in the front and rear garbage boxes 61 and 64 flows into the sewage storage box 63 through the filter screen 62.

The unloading mode is as follows: the discharge of different garbage, as shown in fig. 13, firstly the vehicle is driven to the first discharge point, which is a large-particle garbage point, the rear door body 647 is opened, the box body is lifted by the garbage box body lifting oil cylinder 348, the garbage in the rear garbage box 64 is discharged, and simultaneously the sewage in the sewage storage tank 63 is discharged. At this time, the front door 617 is closed, and the garbage in the front garbage can 61 remains in the front garbage can. When the garbage (sewage) in the rear garbage bin 64 and the sewage storage tank 63 is completely discharged, the vehicle is driven to a second discharging point, the front door body 617 and the rear door body 647 are completely opened, the bin body is lifted through the garbage bin body lifting oil cylinder 348, and the garbage in the front garbage bin body 61 is completely discharged.

When single garbage is unloaded or the garbage does not need to be unloaded separately, the front door body 617 and the rear door body 647 are completely opened, and the garbage box body is lifted by the garbage box body lifting oil cylinder 348, so that the garbage (sewage) in the front garbage box body 61, the rear garbage box body 64 and the sewage storage tank 63 can be completely unloaded.
