[0029] As Figure 1 and Figure 2 shown, the nozzle adjustable purging device of this embodiment includes a nozzle 1, an adjusting member 2 and an adjusting bracket 3. The fixed end of the adjusting member 2 is installed on the vehicle frame 4, the movable end of the adjusting member 2 is movably connected to the adjusting bracket 3, the nozzle 1 is installed at one end of the adjusting bracket 3, the other end of the adjusting bracket 3 is movably connected to the vehicle frame 4, and an opening slot 5 for defining the movement locus of the adjusting bracket 3 is provided on the vehicle frame 4. The adjusting member 2 and the opening slot 5 cooperate with each other to control the rotation angle of the adjusting bracket 3 in the vertical plane, and then adjust the height of the nozzle 1.
[0030] As Figure 1 or Figure 2 shown, the fixed end of the adjusting member 2 is rotatably connected to the vehicle frame 4, and the movable end of the adjusting member 2 is rotatably connected to the adjusting bracket 3. In order to achieve quick replacement, the fixed end of the adjusting member 2 is rotatably connected to the vehicle frame 4 through a pin. This connection structure has high strength and is convenient for disassembly and assembly.
[0031] In this embodiment, the adjusting member 2 serves as a power member for driving the adjusting bracket 3 to move. One end of the adjusting bracket 3 extends into the opening groove 5, and the opening groove 5 restricts the movement trajectory of the adjusting bracket 3. The adjusting member 2 and the opening groove 5 cooperate with each other to control the rotation angle of the adjusting bracket 3 in the vertical plane. The movement of the adjusting bracket 3 drives the movement of the nozzle 1, realizing the height adjustment of the nozzle 1. When operating in a sanitation operation scenario with many obstacles or during a transfer, the height of the nozzle can be appropriately increased to avoid collision damage to the nozzle; when there are fewer obstacles, the height of the nozzle can be appropriately decreased to increase the impact force of the water flow on the road surface and improve the cleaning effect.
[0032] This device uses a high-pressure purging device to clean the road surface. Compared with traditional flushing devices, this device does not need to waste water resources, thus solving the problem that the water demand cannot be met.
[0033] As Figure 3 shown, in this embodiment, the purging device further includes a high-pressure blower 6, and the air outlet of the high-pressure blower 6 is connected to the nozzle 1 through an air duct. The high-pressure blower 6 is located above the nozzle 1 to provide high-pressure wind force for the nozzle 1.
[0034] In this embodiment, the adjusting member 2 includes an electric push rod 21 and a control motor 22 for controlling the stroke of the electric push rod 21. The electric push rod 21 is connected to the control motor 22. The fixed end of the electric push rod 21 is rotatably connected to the vehicle frame 4, and the movable end of the electric push rod 21 is rotatably connected to the adjusting bracket 3.
[0035] In this embodiment, the electric push rod 21 is a cylinder or an oil cylinder.
[0036] In this embodiment, the adjusting bracket 3 includes a first guiding rod 31, a second guiding rod 32, and a connecting rod 33. The movable end of the electric push rod 21 is rotatably connected to one end of the first guiding rod 31 and one end of the second guiding rod 32. The end of the first guiding rod 31 away from the electric push rod 21 is rotatably connected to the vehicle frame 4. The end of the second guiding rod 32 away from the electric push rod 21 is rotatably connected to the connecting rod 33. One end of the connecting rod 33 is rotatably connected to the vehicle frame 4, and the nozzle 1 is installed at the end of the connecting rod 33 away from the vehicle frame 4.
[0037] In this embodiment, the electric push rod 21, the first guiding rod 31, and the second guiding rod 32 are rotatably connected through a rotating shaft 7, and one end of the rotating shaft 7 extends into the opening groove 5.
[0038] As Figure 1As shown in the figure, the first guide rod 31 is composed of two parallel plate-like structures. The tops of the two first guide rods 31 are rotationally connected to the vehicle frame 4 through pins. The top of the second guide rod 32 is provided with a U-shaped connecting part, which is located between the two first guide rods 31. The end of the movable end of the electric push rod 21 extends into the U-shaped connecting part. The rotating shaft 7 sequentially passes through the shaft holes at the bottom ends of the first guide rods 31, the shaft holes on the U-shaped connecting part, and the shaft holes on the movable end of the electric push rod 21, and finally extends into the opening groove 5. A connecting ear is arranged in the middle on the upper side of the connecting rod 33. The bottom end of the second guide rod 32 is rotationally connected to the connecting ear through a pin. The bottom of the opening groove 5 is an arc-shaped structure. When the movable end of the electric push rod 21 extends, it drives the lower end of the first guide rod 31 to make a circular motion around the pin at the upper end of the first guide rod 31, and at the same time drives the second guide rod 32 to move. The movement of the second guide rod 32 drives the connecting rod 33 to move together. The rotating shaft 7 slides along the bottom wall of the opening groove 5. When the electric push rod 21 extends to the maximum stroke, the rotating shaft 7 moves to the end of the opening groove 5 and cannot move further. At this time, the position of the nozzle 1 is the lowest; when the movable end of the electric push rod 21 retracts, the situation is reversed. The shaft holes at the bottoms of the two first guide rods 31 are long strip-shaped sliding grooves, which are used to accommodate manufacturing errors.
[0039] In this embodiment, the nozzle 1 is installed on the connecting rod 33 through a mounting seat 8. The mounting seat 8 includes a first mounting seat 81 and a second mounting seat 82.

[0040] The nozzle 1 is detachably installed on the cylindrical rod 9 through the clamp 10, which is convenient for the disassembly and replacement of the nozzle 1. At the same time, by loosening the bolts on the clamp 10, the angle of the nozzle 1 in the horizontal direction can be manually adjusted, and the nozzle 1 can be adjusted to the best purging direction, further improving the cleaning effect.
[0041] In this embodiment, the connecting rod 33 includes a first connecting rod 331 and a second connecting rod 332 that are parallel to each other, and the length of the first connecting rod 331 is the same as that of the second connecting rod 332.
[0042] The number of the connecting rods 33 can be one or multiple, and the connection strength is ensured by increasing the number of the connecting rods 33.
[0043] In this embodiment, a nozzle interface 11 for introducing a water path into the nozzle 1 is further provided on the nozzle 1. It can realize the introduction of the water path into the nozzle 1 to play a dust suppression role when the high-pressure blower 6 is working.
[0044] As Figure 3 shown, this embodiment also discloses a road sweeper, which includes a road sweeper main body and the above-mentioned nozzle adjustable purging device, and the nozzle adjustable purging device is installed at the front part of the road sweeper main body.
