[0002] With the acceleration of urbanization, urban greening and road cleaning are receiving increasing attention. As an important tool for urban maintenance, the performance and flexibility of sprinkler trucks' spraying devices directly affect the efficiency and quality of green irrigation and road cleaning. Currently, most sprinkler trucks and their spraying devices on the market use a traditional fixed installation method, which is mainly divided into three layout modes: left-biased, center-biased, and right-biased. This fixed installation position of the spraying device limits the diversity of the spraying angle. Whether it is left-biased, center-biased, or right-biased, it can only cover a relatively fixed spraying area. When adjusting the spraying position, it can only be done by adjusting the distance between the vehicle and the curb. This adjustment method is not only cumbersome and inefficient, but also has a limited adjustment range and cannot flexibly respond to changes in road widths, green belt layouts, and specific cleaning needs.

In one embodiment, the connecting frame 1 can be fixed to the sprinkler truck's watering position. In other embodiments, the connecting frame 1 can be hidden inside the sprinkler truck. When spraying greenery, the connecting frame 1 can be extended outside the sprinkler truck. The mobile mechanism 2 includes a mobile drive 21. The mobile drive 21 can be a component with reciprocating motion characteristics, such as a rotary motor or a linear cylinder. In this embodiment, the mobile drive 21 is a rotary motor. The mobile drive 21 can drive the spraying mechanism 3 to move left and right. Left and right can refer to the width direction of the sprinkler truck or the length direction of the sprinkler truck. In this embodiment, left and right refer to the width direction of the sprinkler truck, and the spraying mechanism 3 can move back and forth from left to right along the width direction of the sprinkler truck. The spraying mechanism 3 includes a water inlet pipe 31 and a water outlet nozzle 32. The water inlet pipe 31 is connected to an external water pump and a water tank.

Furthermore, the water outlet nozzle 32 can swing up and down relative to the water inlet pipe 31. On the basis that the spraying mechanism 3 can move left and right, the water outlet nozzle 32 can swing up and down, further expanding the spraying range, spraying height and spraying angle.

[0021] The beneficial effects of the embodiments of the present utility model are as follows:

[0022] The mobile spraying device for a sprinkler truck according to the embodiment of the present utility model is provided with a connecting frame 1, a moving mechanism 2 and a spraying mechanism 3, wherein the connecting frame 1 is fixed on the sprinkler truck, and the moving driving member 21 in the moving mechanism 2 can drive the spraying mechanism 3 to move on the left and right sides of the sprinkler truck, thereby increasing the spraying adjustment range of the sprinkler truck, and at the same time, the spraying mechanism 3 includes a water inlet pipe 31 and a water outlet nozzle 32, and the water outlet nozzle 32 can swing up and down relative to the water inlet pipe 31. During the left and right movement of the spraying mechanism 3, the water outlet nozzle 32 can also swing up and down relative to the water inlet pipe 31, further improving the spraying adjustment range and the spraying angle, thereby improving the working efficiency and operation quality of the sprinkler truck.

[0023] Specifically, the moving mechanism 2 also includes a rotating screw 22 and a moving seat 23. The rotating screw 22 is transmission-connected to the movable end of the moving drive member 21. The rotating drive member can drive the rotating screw 22 to rotate. The rotating screw 22 is provided with a thread, and the moving seat 23 is provided with a thread that engages with the thread of the rotating screw 22. In this way, when the rotating screw 22 rotates, the thread thereon can drive the moving seat 23 to move through the engagement action, and the spraying mechanism 3 is provided on the moving seat 23. When the rotating screw 22 rotates, it can drive the moving seat 23 to move left and right in the width direction of the sprinkler truck, thereby causing the spraying mechanism 3 to move left and right in the width direction of the sprinkler truck.

[0024] In order to limit the moving direction of the spraying mechanism 3, the moving mechanism 2 also includes a guide rod 24, which spans the connecting frame 1 and is parallel to the width direction of the sprinkler truck. The guide rod 24 is arranged parallel to the rotating screw 22. The guide rod 24 passes through the moving seat 23, and the moving seat 23 can move along the guide rod 24. The guide rod 24 guides the moving direction of the moving seat 23 and can provide a certain degree of support for the moving seat 23 to prevent the moving seat 23 from offsetting when it is pressed.

[0025] The spraying mechanism 3 also includes a water inlet flange 33, one end of the water inlet flange 33 is fixed on the movable seat 23, and the other end of the water inlet flange 33 is connected to the water inlet pipe 31. Through the water inlet flange 33, the water inlet pipe 31 can be connected to the movable seat 23, and the water inlet flange 33 is connected to the external water inlet system.

[0026] In order to further expand the spraying range and spraying angle, the spraying mechanism 3 also includes a first rotating drive member 34 and a first turntable 35. The first rotating drive member 34 is preferably a rotating motor, and can also be a rotating cylinder. The first turntable 35 is sealed and connected to one end of the water inlet pipe 31 near the water inlet flange 33. The first rotating drive member 34 is rotatably connected to the first turntable 35. The first rotating drive member 34 can drive the first turntable 35 to rotate, thereby driving the water inlet pipe 31 to swing left and right relative to the movable seat 23. When the first turntable 35 rotates, it can still maintain the seal on the water inlet pipe 31 to ensure that no water leakage or the like occurs during the swinging of the water inlet pipe 31 relative to the movable seat 23. The water inlet flange 33 and the first turntable 35 are in a sealed rotational connection. The structure of this rotational connection belongs to conventional technical means and will not be described in detail here.

[0027] Furthermore, in order to enable the water outlet nozzle 32 to swing up and down relative to the water inlet pipe 31, the spraying mechanism 3 also includes a second driving member 36 and a second rotary disk 37. The second rotating driving member is preferably a rotary motor, or a rotary cylinder. The second rotary disk 37 is sealed between the water outlet nozzle 32 and the water inlet pipe 31. The second rotating driving member is rotatably connected to the second rotary disk 37. The second rotating driving member can drive the second rotary disk 37 to swing up and down, thereby driving the water outlet nozzle 32 to swing up and down relative to the water inlet pipe 31. When the second rotary disk 37 rotates, it can still maintain a seal between the water inlet pipe 31 and the water outlet nozzle 32 to ensure that no water leakage or the like occurs during the process of the water outlet nozzle 32 swinging up and down relative to the water inlet pipe 31. The water inlet pipe 31 and the second rotary disk 37 are in a sealed rotational connection. The structure of this rotational connection is a conventional technical means and will not be described in detail here.

[0028] The spraying mechanism 3 further includes a control box 38 , in which a control mechanism is provided for controlling the moving mechanism 2 and the spraying mechanism 3 . The control box 38 can cover the control mechanism to provide a waterproof effect for the control mechanism.

[0029] Further, see Figure 2 Since the moving mechanism 2 works in water for a long time, in order to prevent the rotating screw 22 from rusting and affecting its operation, a water baffle 11 is provided above the connecting frame 1. The water baffle 11 can cover the rotating screw 22. An avoidance hole 111 is provided on the water baffle 11. The position of the avoidance hole 111 is staggered with the position of the rotating screw 22, so that water falling from the avoidance hole 111 will not fall on the rotating screw 22, thereby protecting the rotating screw 22, and the moving seat 23 can move on the avoidance hole 111.

[0030] The water inlet pipe 31 and the water outlet nozzle 32 are made of stainless steel to ensure that they are not easily rusted, thereby extending their service life. The water outlet nozzle 32 is equipped with a flow meter 321. The flow rate of the water outlet nozzle 32 can be controlled by the flow meter 321.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
