[0006] Furthermore, the spray pipe assembly includes a water distribution pipe, on which a plurality of nozzles are connected at intervals.

[0007] Furthermore, the driver is a pneumatic cylinder, an oil cylinder or an electric push rod.

[0008] Furthermore, the nozzle assembly is fixedly connected to the nozzle fixing seat by means of U-bolts.

[0009] The utility model adopts the above technical solution and has the following beneficial technical effects:

[0010] The utility model has a stable and reliable structure. The device not only meets the road surface cleaning requirements of the pedestrian walkway, but also connects the front nozzle of the road maintenance vehicle through a connecting rod mechanism, controls the nozzle angle through a drive rotator, and increases the cleaning function of vertical devices such as retaining walls and guardrails, thereby achieving multiple uses of one vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention is further described in detail below with reference to the accompanying drawings and specific implementations:

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] Figure 2 This is a schematic diagram of the utility model when used for cleaning a road surface;

[0014] Figure 3 This is a schematic diagram of the utility model when used for cleaning a facade. DETAILED DESCRIPTION

[0015] like Figure 1-3 As shown, the utility model is a multifunctional front nozzle device for a road maintenance vehicle, comprising a base 6, a nozzle assembly 1 and a nozzle fixing seat 3. The base 6 is fixed at the front end of the vehicle. The nozzle assembly 1 comprises a water distribution pipe, and a plurality of nozzles are connected to the water distribution pipe at intervals.

[0016] The nozzle assembly 1 is fixed to the nozzle fixing seat 3 by a U-shaped bolt 2. Specifically, both ends of the U-shaped bolt 2 pass through the nozzle fixing seat 3 and clamp the nozzle assembly 1 between the nozzle fixing seat 3 and the U-shaped bolt 2, and then two nuts are respectively connected to the threaded parts at both ends of the U-shaped bolt 2 to lock the nozzle assembly 1.

[0017] The base 6 and the nozzle fixing seat 3 are connected by a connecting rod structure, which includes a first connecting rod 5 and a second connecting rod 8. The two ends of the first connecting rod 5 and the second connecting rod 8 are respectively hinged to the base 6 and the nozzle fixing seat 3 through a pin 4, and a driver 7 is hinged between the base 6 and the second connecting rod 8. In this embodiment, the base 6 is an inverted U-shaped structure as a whole. The first connecting rod 5 and the second connecting rod 8 are of different lengths, and the first connecting rod 5 is relatively short. The upper end of the first connecting rod 5 is hinged to the side of the base 6 through the pin 4, and the lower end of the first connecting rod 5 is hinged to the top of the nozzle fixing seat 3 through the pin 4; the upper end of the second connecting rod 8 is hinged to the top of the base 6 through the pin 4, and the lower end of the second connecting rod 8 is also hinged to the top of the nozzle fixing seat 3 through the pin 4. One end of the driver 7 is hinged to the other side of the base 6 through the pin 4, and the other end of the driver 7 is hinged to the middle of the second connecting rod 8 through the pin 4. The driver 7 may be a pneumatic cylinder, an oil cylinder or an electric push rod.

[0018] The working principle of the utility model is as follows: when the driving device 7 retracts and drives the nozzle assembly 1 to be parallel to the road surface through the first connecting rod 5 and the second connecting rod 8, the vehicle is used for road cleaning operations; when the driving device 7 extends and drives the nozzle assembly 1 to be perpendicular to the road surface through the first connecting rod 5 and the second connecting rod 8, the vehicle is used for facade cleaning operations (facade devices such as retaining walls and guardrails).

[0019] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
