[0025] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0026] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication between two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] In the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0028] As Figures 1 to 3 shown, the foldable multi-functional high-pressure spray boom of this embodiment includes an installation frame 1, a main spray boom 2, a secondary spray boom 3, a four-bar linkage mechanism 4, and a folding driving member 5. The main spray boom 2 is horizontally installed on the installation frame 1, and the secondary spray booms 3 are respectively movably installed at both ends of the installation frame 1 through the four-bar linkage mechanism 4. The fixed end of the folding driving member 5 is hinged to the installation frame 1, and the telescopic end of the folding driving member 5 is hinged to the four-bar linkage mechanism 4. The folding driving member 5 drives the four-bar linkage mechanism 4 to move, so that the secondary spray boom 3 rotates outwards to the unfolded state or rotates inwards to the folded state. Nozzles 6 are provided on both the main spray boom 2 and the secondary spray boom 3.

[0029] On the basis of the existing main spray bar 2, two additional auxiliary spray bars 3 are provided for this product. One auxiliary spray bar 3 is installed on one side of the mounting bracket 1, and the other auxiliary spray bar 3 is installed on the opposite side of the mounting bracket 1. The two auxiliary spray bars 3 are respectively connected to the four-bar linkage mechanisms 4 on the same side, and the four-bar linkage mechanisms 4 are respectively connected to the corresponding folding driving members 5. The folding driving members 5 provide driving force for the four-bar linkage mechanisms 4. When the telescopic ends of the folding driving members 5 extend, they drive the four-bar linkage mechanisms 4 to move. The movement of the four-bar linkage mechanisms 4 drives the auxiliary spray bars 3 to rotate outwards, and finally they can be unfolded to the horizontal state. When the telescopic ends of the folding driving members 5 retract, they drive the four-bar linkage mechanisms 4 to move in the reverse direction. The reverse movement of the four-bar linkage mechanisms 4 drives the auxiliary spray bars 3 to rotate inwards, and finally the auxiliary spray bars 3 can be folded inwards to the horizontal state. When cleaning the road surface, the telescopic ends of the folding driving members 5 drive the four-bar linkage mechanisms 4 to move. The movement of the four-bar linkage mechanisms 4 drives the auxiliary spray bars 3 to rotate outwards and unfold to spray and wash the road surface, greatly increasing the cleaning range, reducing the number of operations, and significantly improving the operation efficiency. When the auxiliary spray bars 3 rotate outwards by a certain angle and stand up, they can clean the road edges on both sides, and the applicability of the operation scenario is strong; when not working, the auxiliary spray bars 3 rotate inwards and fold, which is convenient for transportation.

[0030] The number of the auxiliary spray bars 3 is not limited to two. In other embodiments, the number of the auxiliary spray bars 3 can be designed to be 3, 4 or more according to needs.

[0031] In this embodiment, the main spray bar 2 and the two auxiliary spray bars 3 are respectively and independently communicated with the external water supply system. The external main controller controls the main spray bar 2 and each auxiliary spray bar 3 separately. When cleaning a road surface with a width of 1.5 m, the two auxiliary spray bars 3 on the left and right are both retracted, and the main controller controls the main spray bar 2 to perform spraying and washing. When cleaning a road surface with a width of 2 m, one of the auxiliary spray bars 3 is retracted, and the main controller controls the main spray bar 2 and the other auxiliary spray bar 3 to perform spraying and washing. When cleaning a road surface with a width of 2.5 m, the two auxiliary spray bars 3 on the left and right are both unfolded for spraying and washing. This product has excellent flexibility and applicability.

[0032] In this embodiment, the rotation angle of the auxiliary spray bar 3 is 0° - 180°.

[0033] When cleaning the left road edge + road surface, the folding driving member 5 on the left drives the four-bar linkage mechanism 4 to move. The movement of the four-bar linkage mechanism 4 drives the auxiliary spray bar 3 on the left to rotate to 90°, and the main controller controls the main spray bar 2 and the auxiliary spray bar 3 on the left to perform spraying and washing; when cleaning the right road edge + road surface, the folding driving member 5 on the right drives the four-bar linkage mechanism 4 to move. The movement of the four-bar linkage mechanism 4 drives the auxiliary spray bar 3 on the right to rotate to 90°, and the main controller controls the main spray bar 2 and the auxiliary spray bar 3 on the right to perform spraying and washing; when cleaning the left road edge + right road edge + road surface, the folding driving members 5 on the left and right drive the four-bar linkage mechanisms 4 to move. The movement of the four-bar linkage mechanisms 4 drives the two auxiliary spray bars 3 on the left and right to rotate to 90°, and the main controller controls the main spray bar 2 and the two auxiliary spray bars 3 on the left and right to perform spraying and washing.

[0034] In this embodiment, the four-bar linkage 4 includes a fixed seat 41, a driving connecting frame 42, a driven connecting frame 43, and a connecting rod 44. The fixed seat 41 is fixedly connected to the mounting frame 1. The driving connecting frame 42 is in the shape of a triangular plate. The first vertex of the driving connecting frame 42 is hinged to one end of the fixed seat 41. The second vertex of the driving connecting frame 42 is hinged to the telescopic end of the folding driving member 5. The third vertex of the driving connecting frame 42 is hinged to one end of the connecting rod 44. The other end of the connecting rod 44 is hinged to one end of the driven connecting frame 43. The other end of the driven connecting frame 43 is hinged to the end of the fixed seat 41 away from the driving connecting frame 42. One end of the auxiliary spray bar 3 is mounted on the driven connecting frame 43.

[0035] The fixed seat 41, the driving connecting frame 42, the driven connecting frame 43, and the connecting rod 44 form a four-bar structure. When the telescopic end of the folding driving member 5 extends, it drives the second and third vertices of the driving connecting frame 42 to rotate outward around the first vertex to make a circular motion. The third vertex of the driving connecting frame 42 drives the connecting rod 44 to move. The movement of the connecting rod 44 drives the driven connecting frame 43 to move. The driven connecting frame 43 drives the auxiliary spray bar 3 to rotate outward and unfold. When the telescopic end of the folding driving member 5 retracts, it drives the second and third vertices of the driving connecting frame 42 to rotate inward around the first vertex to make a circular motion. The third vertex of the driving connecting frame 42 drives the connecting rod 44 to move in the reverse direction. The movement of the connecting rod 44 drives the driven connecting frame 43 to move in the reverse direction. The driven connecting frame 43 drives the auxiliary spray bar 3 to rotate inward and fold.

[0036] In this embodiment, a support rod 7 is provided between the fixed seat 41 and the mounting frame 1. One end of the support rod 7 is fixedly connected to the mounting frame 1, and the other end of the support rod 7 is fixedly connected to the fixed seat 41.

[0037] In this embodiment, a connecting plate 8 is provided between the auxiliary spray bar 3 and the driven connecting frame 43. One end of the connecting plate 8 is hinged to the middle of the driven connecting frame 43, and the other end of the connecting plate 8 is detachably connected to the auxiliary spray bar 3. An adjusting structure 9 for adjusting the angle of the auxiliary spray bar 3 in the horizontal direction is provided between the driven connecting frame 43 and the connecting plate 8.

[0038] In this embodiment, the adjusting structure 9 includes a shock-absorbing spring 91 and an adjusting bolt 92. One end of the shock-absorbing spring 91 is connected to the end of the driven connecting frame 43 away from the fixed seat 41, and the other end of the shock-absorbing spring 91 is connected to the connecting plate 8. The adjusting bolt 92 is arranged at the bottom of the end of the driven connecting frame 43 away from the fixed seat 41.

[0039] Axially along the adjusting bolt 92, the force of the shock-absorbing spring 91 on the connecting plate 8 matches the force of the adjusting bolt 92 on the connecting plate 8, forming an action and reaction force. Generally, the connecting plate 8 and the driven connecting frame 43 can be regarded as an integral structure, and the connecting plate 8 moves smoothly following the movement of the driven connecting frame 43. When encountering an obstacle on the ground, the shock-absorbing spring 91 undergoes slight deformation, and the auxiliary spray bar 3 and the connecting plate 8 produce slight jolts, achieving the purpose of anti-collision and obstacle avoidance.

[0040] In this embodiment, the folding driving member 5 is a cylinder or an oil cylinder.

[0041] In this embodiment, the main spray bar 2 is detachably mounted on the mounting frame 1, which facilitates the disassembly, repair, and replacement of the main spray bar 2.

[0042] This embodiment also discloses a cleaning machine, including a cleaning machine main body and the above-mentioned folding multi-functional high-pressure spray bar, and the mounting frame 1 of the folding multi-functional high-pressure spray bar is mounted on the cleaning machine main body.
