Detailed implementation manners

[0025] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0027] The following combines Figures 1 to 6 to specifically illustrate a side spray position adjustment structure according to an embodiment of the present utility model.

[0028] As Figures 1 to 6As shown in the figure, a side spray position adjustment structure according to an embodiment of the present invention includes: an integrally formed mounting plate 102, an adjustment limit plate 104, a rotating bracket 106, a spring plunger 110, a pin shaft 108, and so on. A plurality of adjustment holes 1042 are provided on the adjustment limit plate 104, and the plurality of adjustment holes 1042 are evenly distributed along an arc. A connection through hole I 1044 is provided at the center of the circle corresponding to the arc. One end of the rotating bracket 106 is rotatably connected to the connection through hole I 1044 through the pin shaft 108, so that it can rotate relative to the adjustment limit plate 104. A spring plunger 110 is installed on the rotating bracket 106. The spring plunger 110 and the pin shaft 108 are arranged at an interval, and the interval is equal to the radius of the circle corresponding to the arc. In this way, when the rotating bracket 106 rotates with the connection through hole I 1044 as the center, the spring plunger 110 rotates along the arc where the adjustment holes 1042 are located, and is clamped into different adjustment holes 1042 as the rotating bracket 106 rotates, thereby realizing the adjustment of the height position of the spray gun installed on the rotating bracket 106. The side spray position adjustment structure has a simple structure and strong reliability. Without relying on the synchronous up and down movement of the cleaning brush, it can realize small-scale multi-level adjustment of the spraying height. Without disassembling the screws, the adjustment is simple and fast, which is beneficial to targeted spraying according to the road conditions, improving the spraying effect, and further improving the cleaning effect and cleaning efficiency.

[0029] Further, as Figure 6 shown, the rotating bracket 106 includes: an integrally formed rotating plate 1062 and a spray gun connecting plate 1064. The rotating plate 1062 and the spray gun connecting plate 1064 are perpendicularly connected. The pin shaft 108 is installed in a connection through hole II 1062-1 opened at one end of the rotating plate 1062. The spray gun connecting plate 1064 is in a shape similar to an L, and the L-shaped angle is connected to the other end of the rotating plate 1062. A spray gun connection hole 1064-1 is opened on the spray gun connecting plate 1064 at the other end. A spring plunger mounting plate 1066102 is provided on the side of the rotating plate 1062 and is at the same end as the connection through hole II 1062-1. The spring plunger mounting plate 1066102 is in a shape similar to a Z, and a spring plunger mounting hole 1066-1 is opened at the upward top end. The spring plunger 110 is fixedly installed in the spring plunger mounting hole 1066-1. Thus, the spray gun is fixed on the spray gun connecting plate 1064 through a clamp, and the spray port of the spray gun faces the side. When the rotating bracket 106 rotates, the spray port rotates in an arc shape to realize the adjustment of the spraying height.

[0030] Further, as Figure 4 and Figure 5As shown, the mounting plate 102 is vertically connected to the top side of the adjustment limit plate 104, and is provided with a fixed connection hole 1022, and can be mounted on the frame through the fixed connection hole 1022. The two sides of the adjustment limit plate 104 are vertically connected to the protective plate 1046, and the protective plate 1046 and the adjustment limit plate 104 are integrally formed to play a protective role. The corners of the mounting plate 102, the protective plate 1046, and the adjustment limit plate 104 are arc-shaped, which further improves safety.

[0031] Furthermore, if Figure 5 As shown, the diameter of the adjustment hole 1042 is 3 mm, the diameter of the circle corresponding to the arc of the adjustment hole 1042 is 60 mm, the central angle is greater than 180°, and the central angle corresponding to two adjacent adjustment holes 1042 is 15°, thereby making the adjustment of the injection height more convenient and reliable, and the spring plunger 110 can be more firmly clamped into different adjustment holes 1042, and when clamped into the adjustment hole 1042, it is highly reliable.

[0032] Furthermore, the length of the rotating bracket 106 is 100 mm. When the side spray position adjustment structure is installed on the frame, the spray gun connecting plate 1064 faces the side, and the fixed connection position of the spray gun on the spray gun connecting plate 1064 can be adjusted along the forward and backward travel direction to achieve height range control, that is, the farther the distance between the spray gun's injection port and the pin shaft 108, the larger the adjustable height range and the amplitude of each adjustment.

[0033] The working process of a side spray position adjustment structure proposed by the utility model is as follows:

[0034] It is fixedly connected to one side of the frame through the fixed connecting hole 1022 on the mounting plate 102; the rotating bracket 106 is rotatably connected to the connecting through hole Ⅰ1044 of the adjusting limit plate 104 through the pin shaft 108; the spring plunger 110 is fixedly mounted on the spring plunger mounting plate 1066102 of the rotating bracket 106, and the spring plunger 110 is clamped with the adjusting hole 1042 of the adjusting limit plate 104; the metal connecting pipe of the spray gun is fixedly connected to the spray gun connecting plate 1064 through a clamp, and the injection port of the spray gun faces the side; by turning the spray gun or the spray gun connecting plate 1064 of the rotating bracket 106, the rotating bracket 106 is rotated around the adjusting limit plate 104, and the spring plunger 110 is clamped into different adjusting holes 1042 as the rotating bracket 106 rotates, thereby realizing the height position adjustment of the spray gun installed on the rotating bracket 106.

[0035] The small sanitation vehicle includes the above-mentioned side spray position adjustment structure, which is fixedly connected to one side of the vehicle frame.
