In this regard, a further preferred embodiment of this embodiment further includes a crash wheel 70, the crash wheel 70 is a circular structure with a hole formed in the middle, when assembling, the nozzle 52 penetrates through the hole in the middle of the crash wheel 70, so that the crash wheel 70 is sleeved outside the nozzle 52, and the crash wheel 70 is preferably made of a soft elastic material to buffer the impact, the collision, the extrusion, the friction and other acting forces from the road surface obstacle. The water outlet 521 of the nozzle 52 is preferably exposed outside the anti-collision wheel 70, so that the nozzle 52 can flush the road surface, and the direction of the nozzle 52 can be clearly identified by an operator in real time during the process of adjusting the direction of the nozzle 52, thereby improving the accuracy of adjusting the direction of the nozzle 52.

In the actual use process of the crash wheel 70, the direction of the acting force of the crash wheel 70 collided with the obstacle may not be determined, and if the force of the crash wheel 70 is the radial force from the crash wheel 70, the crash wheel 70 is preferably rotatably fitted outside the nozzle 52, and the rotation axis of the crash wheel 70 is consistent with the length direction of the nozzle 52, so that the crash wheel 70 can rotate adaptively when being stressed to buffer the radial acting force, so as to prevent the crash wheel 70 from directly transmitting the acting force to the joint of the joint 51 and the connecting bracket 10, and further prevent the corresponding structure from being damaged. And the anti-collision wheel 70 is in limit fit with the nozzle 52 along the length direction of the nozzle 52.

The water outlet 521 of the nozzle 52 may be flat, so that the water flow sprayed from the water outlet 521 is in a water curtain shape, which is beneficial to increase the area of the road surface to be washed in unit time.

In fig. 1 to 5, a high pressure hose 60 is the water input of the road flushing device for connection to a water source for supplying high pressure water, where the water source may be water pumped by a water pump and pumped out at a corresponding flow rate. High-pressure rivers are through universal copper joint by the spout 52 department with water blowout, realize the function that washes the road surface, and universal copper joint can carry out 360 angular adjustment along E direction in the picture to the realization is washed the dead angle free on road surface, has avoided traditional road high pressure cleaning vehicle and road sweeper to a lot of places on road to wash the problem that can not arrive, and this road washing unit simple structure, simple to operate, the maintenance of being convenient for. The universal copper joint is understood to be the joint 51 described above.

The universal copper joint is connected with the connecting support 10 and the high-pressure hose (the adapter tube 61), and the nozzle 52 is connected with the universal copper joint through a tube thread, so that the sealing effect is better. Wherein, the universal copper joint is connected with the high-pressure hose by screw thread, the installation is simple, the sealing effect is good, and the water leakage is not easy.

The universal copper joint is connected and limited with the connecting support 10 through the inner hexagonal steel and the outer hexagonal steel, so that the phenomenon that the universal copper joint rotates due to the existence of freedom degree during working is avoided.

And an anti-collision wheel 70 is arranged between the universal copper joint and the nozzle 52, so that an anti-collision effect is realized, and the mechanism is prevented from being damaged due to ground collision in the work.

The above-mentioned road washing unit that this embodiment provided, it can use on road high pressure sewer flushing vehicle or road sweeper, and it can improve road high pressure sewer flushing vehicle and road sweeper and carry out the effect of washing to the road, has also improved the adaptability to various roads greatly, has solved traditional road washing unit and has run into the problem that the effect is not good and fragile when complicated road surface, this mechanism simple structure, simple to operate, and the facilitate promotion is used.

The embodiment also provides a road cleaning vehicle applying the road washing device, which comprises a chassis 91 and a cab arranged on the chassis 91, wherein the transition bracket 80 is hinged and installed below the chassis 91 through a first hinge shaft 81, the handle 92 is installed in the cab through a third hinge shaft 94, and the length direction of the handle 92 is consistent with the front and back direction of the cleaning vehicle; the two sets of flushing devices are arranged on two sides of the cleaning vehicle in the width direction respectively.
