[0004] Another objective of this utility model is to provide a water tanker truck that can solve the problem of the single function of traditional water tankers and realize multi-functional, multi-directional, and multi-path water supply operations.

[0005] The technical solution of this utility model is implemented as follows: A multi-functional spraying device for a tractor-mounted water tanker truck, the water tanker truck having a water tank, comprising: The multi-functional water outlet system includes a main water spray pipe located at the rear of the water tanker. The main water spray pipe has one inlet and multiple outlets. The inlet is sealed and connected to the water tank. The outlets are equipped with nozzles or water spray branch pipes. Each water spray branch pipe is connected to an independently controlled valve for connecting different types of water supply devices to achieve multi-functional, multi-directional, and multi-path water supply operations. An operating platform is fixed at the rear of the water tanker truck for the operator to stand on; A high-flow-rate water cannon is mounted on the operating platform via a bracket. The inlet end of the high-flow-rate water cannon is connected to a water tank via a pipeline, and it can be rotated horizontally and adjusted in pitch for long-distance, high-flow-rate spraying operations.

[0006] Furthermore, the main water spray pipe is a straight pipe and is arranged laterally at the rear of the water tanker. Both ends of the main water spray pipe are closed ends.

Multiple water outlets are evenly arranged along the axial direction on the rear side of the main water spray pipe. The nozzles are installed at the water outlets at both ends, and the water spray branch pipes are installed at the multiple water outlets in the middle.

[0007] Furthermore, the interface of the water spray branch pipe port is threaded or quick-release snap-fit ​​type, and is compatible with at least one external water supply device among steel wire hose, irrigation tape, high-pressure water gun, and faucet.

[0008] Furthermore, the high-flow-rate water cannon is provided with an installation part, and the top of the bracket is provided with a docking part; The mounting part and the docking part are connected in all directions by a ball joint structure.

[0010] Furthermore, the water tanker is also equipped with a water pump system, which is used to supply water to the main water spray pipe and the high-flow-rate water cannon.

[0011] Furthermore, the water pump system includes a booster pump, the water tank has a water delivery pipe, the end of the water delivery pipe is connected to one port of a tee connector, the other two ports of the tee connector are respectively connected to the inlet of the main water spray pipe and the inlet of the high-flow-rate water cannon through pipes, the booster pump is installed on the water delivery pipe, and the nozzle mode of the high-flow-rate water cannon is adjustable, supporting columnar, mist or fan-shaped water output.

[0012] Furthermore, the water tanker is compatible with a full range of tractors from 50 horsepower to 200 horsepower, and is connected via standard suspension or traction interface.

[0013] A water tanker truck includes a multi-functional spraying device for the tractor-mounted water tanker truck.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This solution features multiple independent water outlets for installing sprinklers and water supply branches.

[0024] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Currently, water tankers are widely used as water supply equipment in scenarios such as agricultural irrigation, road dust suppression, and site cleaning. However, traditional water tankers have the following significant drawbacks: 1. Limited functionality Most water tankers only have basic water delivery capabilities, usually with only one outlet, and can only be connected to a simple hose for localized watering or rinsing, making them unable to adapt to diverse operational needs.

[0026] 2. Low work efficiency When irrigating large areas of farmland, it is necessary to move vehicles or lay pipes manually, which is time-consuming and labor-intensive. Lacking long-range, high-volume spraying methods, it is difficult to quickly cover a wide area.

[0027] 3. Poor scalability The original structure did not have multiple interfaces or modular design, making it difficult to connect different types of work devices (such as high-pressure water cannons, drip irrigation tapes, car wash guns, etc.).

[0028] Therefore, it is urgent to structurally modify traditional water tankers to improve their multifunctionality, operational efficiency, and ease of operation.

[0029] To address the aforementioned issues, this solution aims to provide an upgraded spraying device based on a tractor-mounted water tanker platform, achieving at least one of the following objectives: 1. Addressing the pain point of traditional water tankers having "limited functionality"; 2. Enables free switching between multiple operation modes (such as irrigation, dust removal, cleaning, etc.); 3. Increase the working area and water resource utilization rate per unit time; 4. Improve operational safety and human-computer interaction experience; Example 1: A multi-functional spraying device for a tractor-mounted water tanker like Figure 1 and Figure 2 As shown (a schematic diagram of the water tanker 1 and a rear view of the water tanker 1, respectively), this embodiment provides a multi-functional spraying device for a tractor-mounted water tanker, which is mainly used for various operational scenarios such as agricultural irrigation, road dust suppression, and site cleaning.

[0030] The device is mainly used in water tanker truck 1 and includes a multi-inlet system, a high-flow-rate water cannon 8, an operating platform 6, and a water supply and control system.

[0031] 1. Water tanker truck The water tanker 1 includes a water tank 2, a water pump system, piping assembly, and a chassis. The water tank 2 has a volume of 3–8 cubic meters, is made of corrosion-resistant materials (such as polyethylene or stainless steel), and is fixed to a general-purpose tractor's rear three-point suspension or an independent towing chassis. The water pump system can be driven by a diesel engine or the tractor's power take-off shaft (PTO), providing a continuous high-pressure water flow with a maximum operating pressure of 0.8–1.2 MPa.

[0032] II. Multifunctional water outlet system 9 A metal or plastic crossbar is installed laterally at the rear of the water tanker 1. The crossbar is a straight tubular structure and is installed laterally at the rear of the water tanker 1. Both ends of the water spray main pipe 3 are closed. A water inlet is set in the middle of the front side of the water spray main pipe 3. Six water outlets are evenly arranged along the axial direction (i.e., laterally or in the width direction of the water tanker 1) on the rear side of the water spray main pipe 3. Among them, the water outlets at both ends of the water spray main pipe 3 are equipped with nozzles 4, and the four water outlets in the middle are equipped with water spray branch pipes 5. These four water outlets in the middle are independent functional water outlets (i.e., the first water outlet, the second water outlet, the third water outlet, and the fourth water outlet). The distance between adjacent water outlets is about 30 to 50 centimeters.

[0033] Each water outlet is equipped with an independently controlled valve. For example, each spray branch pipe 5 is equipped with a manual ball valve or solenoid valve, and uses standard interface types (such as threaded interfaces and quick-connect snap-fit ​​couplings) to quickly connect to different types of external water supply devices, such as: Steel wire reinforced hose (can be used for long-distance water delivery after connection); Irrigation tape or drip irrigation pipe (which can be used for irrigation of strip-sown crops in farmland after connection); High-pressure water gun (can be used for vehicle washing or building cleaning after connection); Mobile rotating sprinkler head 4 (can be used for green belt maintenance after connection); Faucet (can be used for various purposes such as hand washing and face washing after connection).

[0034] Each outlet is a branch pipe connected to the main water supply pipe (i.e., the water supply pipe of water tank 2). It can be individually controlled to open and close via valves, or opened simultaneously to achieve synchronous operation in multiple areas. Water flow is uniformly supplied by a water pump system, and a pressure stabilizing valve can also be installed in the system to prevent pressure imbalance caused by single-circuit opening.

[0035] III. High-flow water cannon 8 An operating platform 6 is set at the rear of the water tanker 1, and a high-flow water cannon 8 is installed on the operating platform 6 as an active spraying unit, which is used for large-area coverage operations, such as dust suppression in mining areas and large lawn spraying.

[0036] The high-flow-rate water cannon 8 is fixed to the bracket 7 via an adjusting mechanism 10. The bracket 7 is fixed to the operating platform 6. The high-flow-rate water cannon 8 is equipped with a mounting part, and the top of the bracket 7 is equipped with a docking part. The adjusting mechanism 10 can adopt a ball joint structure, and the mounting part and the docking part are universally connected through the ball joint structure to achieve free adjustment of the spray angle. The water cannon nozzle can have a mode adjustment function, which can be switched to a columnar jet (long distance), a mist diffusion (dust suppression), or a fan-shaped spray (wide coverage) via a handwheel. Under rated pressure, the maximum range can reach more than 35 meters.

[0037] IV. Operating Platform 6 A fixed operating platform 6 is installed at the rear of the water tanker 1 for operators to centrally control the equipment. The operating platform 6 is approximately 90-110 cm above the ground, with an anti-slip surface and guardrails and handrails 0.9-1.1 meters (e.g., 1 meter) high around it to ensure safety during high-altitude operations. The anti-slip structure can be anti-slip textures, anti-slip mats, or anti-slip steel plates installed on the top surface of the operating platform 6. The guardrails have a movable door, allowing operators to access the operating platform 6. The height of the operating platform 6 is suitable for an adult standing and provides a field of vision covering the direction of the water cannon spray and the operating area at the rear of the vehicle.

[0038] The water pump system on the water tanker 1 is used to supply water to the main water spray pipe 3 and the high-flow water cannon 8.

[0039] In one optional implementation, the water pump system includes a booster pump, the water tank 2 has a water delivery pipe, the end of the water delivery pipe is connected to one port of a tee connector, and the other two ports of the tee connector are respectively connected to the inlet of the main water spray pipe 3 and the inlet of the high-flow-rate water cannon 8 through pipes, and a booster pump is installed on the water delivery pipe.

[0040] The water tanker truck 1 is compatible with a full range of tractors from 50 horsepower to 200 horsepower, and uses standard suspension or traction interface connections.

[0041] Example of overall machine workflow: When in use, this device is towed by a tractor into the work area. Select the appropriate working mode based on different task requirements: Farmland irrigation mode: Open two or more water outlets, connect to external irrigation belts, and supply water to the fields on both sides respectively; Road dust suppression mode: Activate high-flow water cannon 8, adjust to mist + medium elevation angle, and drive slowly along the road to achieve continuous dust suppression; Vehicle washing mode: Open a single water outlet to connect a high-pressure water gun, and use a water cannon to assist in rinsing high areas. Emergency firefighting support: Fully activate the system to spray the fire source area at maximum flow rate.

[0042] All operations can be completed independently by one staff member on the operating platform 6, without the need for frequent getting on and off the vehicle or multiple people to work together.

[0043] Other possible implementation methods (further explanation) Those skilled in the art can make adaptive adjustments to the above embodiments according to actual needs, for example: By changing the number of water outlets to three or five, multi-path water supply can still be achieved.

[0044] Example 2 The adjustment mechanism 10 in this embodiment differs from that in embodiment 1. The adjustment mechanism 10 includes: 1. Horizontal rotating mechanism: A slewing bearing can be used to achieve 360° continuous rotation. The inner ring of the slewing bearing is welded to the bracket 7, and the outer ring is connected to the water cannon base; a mechanical limit stop is also provided to limit the effective working angle range to 270° to prevent water pipe entanglement. The drive method is manual rotation drive, or it can be driven by an electric slewing motor.

[0045] 2. Pitch adjustment mechanism 10: The high-flow-rate water cannon 8 is hinged to the mounting section via a trunnion pin, forming a pitch-rotation joint. It's important to note that the trunnion pin structure is a very common and mature hinge connection structure in mechanical engineering, used to achieve relative rotational movement between two components (such as vertical swinging, pitch adjustment, etc.). Pitch adjustment can be achieved manually via the pitch adjustment mechanism 10, or by a drive mechanism, for example, by connecting an electric push rod to the tail of the water cannon, with the other end of the push rod hinged to the vehicle frame. The extension and retraction of the electric push rod moves the tail of the water cannon up and down, thereby changing the nozzle elevation angle, with an adjustment range of -10° to +60°.

[0046] Other possible implementation methods (further explanation): Pitch adjustment is achieved by replacing electric push rods with hydraulic cylinders; Add a PLC controller and a wireless remote control module to achieve semi-automatic or remote intelligent control; Add a folding seat or sunshade to the operating platform 6 to improve human-machine comfort.

[0047] The beneficial effects of the technical solution of this utility model are: 1. Multifunctional Water Outlet System 9: Equipped with multiple independent water outlets, each with an independent control valve, allowing for quick connection to various external water supply devices, such as: steel wire reinforced hoses (for long-distance water delivery), irrigation tape / drip irrigation pipes (for farmland irrigation), high-pressure water guns (for vehicle washing and building cleaning), and mobile sprinkler arrays (for green belt maintenance). By connecting different types of external water supply devices, it can achieve multifunctional, multi-directional, and multi-path water supply operations; breaking the traditional single-outlet limitation, it can achieve "one vehicle for multiple uses" and meet the simultaneous water demand of different work areas.

[0048] 2. High-flow-rate water cannon 8 (active operation unit): specially designed for long-distance, high-intensity spraying tasks, such as dust suppression at construction sites / mining areas / factories, large-area lawn or crop foliage spraying, and emergency fire-fighting auxiliary water supply; it has a large water flow rate, long range (expected to reach 20-40 meters, depending on pump pressure), adjustable nozzles (multiple modes such as mist, column, and fan), and has a horizontal rotation and pitch adjustment mechanism to expand the coverage angle; it is fixed to the operating platform 6 by the bracket 7, with strong stability, shock resistance and vibration prevention, giving the water tanker 1 the ability to actively intervene in the environment, significantly improving the response speed to sudden and large-scale operation tasks.

[0049] 3. The personnel operation platform 6 (human-machine collaboration hub) is located at the rear of the water tanker 1. The operation platform 6 can be equipped with anti-slip pedals, guardrails, and handrails to ensure the safety of high-altitude operations. The operator can operate the high-flow water cannon 8 from one station on the operation platform 6. The operator has a wide field of vision on the operation platform 6, which makes it easy to observe the spraying effect and adjust the spray angle and spray direction of the water cannon in real time. It also serves as entertainment while working.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
