The cleaning contents include garbage cleaning, fallen leaf cleaning, snow and ice removal, road oil pollution treatment, etc. It is suitable for various scenarios such as urban main roads, secondary roads, and rural roads. Among them, the road suction and sweeping vehicle is a high-efficiency and environmentally friendly equipment specially designed for visible garbage on urban roads. It can perform suction and collection operations on fallen leaves, small garbage, etc. on the road, and is an important tool for modern urban sanitation work.

[0003] However, the cleaning equipment of traditional road cleaning vehicles has a single function and it is difficult to take into account the functions of blowing or collecting garbage at the same time, especially in areas with a large coverage area where repeated operations are required. In addition, the cleaning method of the cleaning equipment is fixed and it is difficult to adapt to different environmental requirements, which increases manpower and time costs and cannot meet the needs of efficient cleaning. In addition, when inhaling larger or more sticky garbage, conventional negative pressure vacuum equipment is prone to pipe blockage due to garbage jamming or aggregation, and usually requires manual shutdown for cleaning, which not only increases the frequency of operation interruptions, but may also cause damage to internal components of the equipment.

A rear box door 24 is installed on one side of the second box 23. The first box 21 is used to store garbage and leaves extracted by negative pressure, and the second box 23 is used to install a vehicle battery assembly and a controller. By adding the side box door 22 and the rear box door 24, the garbage and key components inside the first box 21 and the second box 23 can be exposed, which is convenient for comprehensive inspection or replacement, so that the maintenance space design of the entire vehicle is reasonable.

[0029] like Figure 1 , Figure 3 and Figure 6 As shown, the cleaning mechanism 4 is installed on the bottom of both sides of the electric tricycle 1. The cleaning mechanism 4 includes two groups of connecting rods 42, each group of connecting rods 42 has two connecting rods, and the two groups of connecting rods 42 are respectively hinged to the bottom of both sides of the electric tricycle 1.

[0030] The cleaning mechanism 4 is installed at the bottom of both sides of the electric tricycle 1, and uses two sets of connecting rods 42 to support and lift the first motor 43 and the brush plate 41 up and down. The first motor 43 can drive the brush plate 41 to rotate and clean the road surface in forward and reverse directions, and collect dust and leaves under the vehicle body or in the opposite direction to both sides of the road.

[0031] Furthermore, in order to facilitate the operator to pull the connecting rod 42 to drive the brush plate 41 to lift and lower, the outer wall of each group of connecting rods 42 is hinged with a handle 44.

The air outlet of the fan 51 is connected to the telescopic tube 54.

[0033] The blowing and suction mechanism 5 is located on the first box body 21, and generates negative pressure through the fan 51, and then draws garbage into the box body through the telescopic tube 54 and the leaf inlet channel 52. The air outlet of the fan 51 can also use positive pressure to blow the road surface, and further blow the dust and fallen leaves to the side of the road to improve the cleaning effect.

[0034] Further, see Figure 4 and Figure 5The blowing and suction mechanism 5 also includes a second motor 53, which is installed on the first box body 21. A rotating rod 55 is connected to one side of the fan 51 through a bearing. A transmission wheel 57 is installed on the rotating shaft of the second motor 53 and one end of the rotating rod 55. The two transmission wheels 57 are connected through a belt 56. A plurality of cutting blades 58 are distributed equidistantly on the outer wall of the rotating rod 55 according to the circumference, and the cutting blades 58 are located inside the fan 51.

[0035] The second motor 53 can drive the transmission wheel 57 on its rotating shaft to rotate, and use the belt 56 to drive another transmission wheel 57 and the rotating rod 55 to rotate. The multiple cutting blades 58 on the outer wall of the rotating rod 55 can shred the larger garbage sucked in by the fan 51 to avoid clogging the channel.

[0036] It should be noted that the telescopic tube 54 is a corrugated hose.

[0037] like Figure 1-Figure 7 As shown, the blowing and suction supporting mechanism 3 is installed at the bottom of the electric tricycle 1, and the blowing and suction supporting mechanism 3 includes two movable rods 32, and the two movable rods 32 are symmetrically hinged to the bottom of the electric tricycle 1, and the ends of the movable rods 32 are hinged with an I-shaped frame 31, and the bottom of the I-shaped frame 31 is installed with a walking wheel 33.
