[0002] In the field of modern agriculture and landscaping, the mechanization and automation of irrigation and spraying operations are constantly improving. The traditional manual spraying method has been gradually replaced by various mechanized equipment due to its low efficiency and high labor intensity. At present, the commonly used mechanized equipment includes motorized sprayers mounted on agricultural vehicles, water spraying vehicles with tanks, and water pumping systems with pumps. Although these equipment have greatly improved the operating efficiency, they still have some technical and operational limitations.

[0003] Existing mechanized irrigation and spraying equipment usually requires separate power sources for different functional systems. For example, the vehicle's travel system, the hydraulic pump in the spraying system, and the pumping equipment in the irrigation system need to be driven by different power sources, resulting in high costs. In addition, multiple power sources and related control systems will also take up more space, resulting in an increase in the size and weight of the vehicle, which is inconvenient to operate in narrow or complex environments. Summary of the invention

[0012] By adopting the above further solution, the blowing unit and the high-pressure fluid delivery component in the spraying system can also adjust the power input according to different operation requirements.

[0013] Furthermore, the spray assembly also includes a baffle, which is fixedly connected to the spray frame, and the spray head is arranged between the spray frame and the baffle, and the baffle is used to make the airflow generated by the blowing unit blow toward the spray head.

[0014] By adopting the above-mentioned further solution, the setting of the baffle can not only ensure that the airflow blows toward the nozzle, thereby ensuring the diffusion effect of the water mist, but also prevent the headwind from affecting the airflow generated by the blowing unit, ensuring that even in a windy environment, the airflow generated by the blowing unit can still stably blow toward the nozzle.

[0015] Furthermore, the spray frame includes a first support plate with a central opening, a second support plate with a central opening, and a support plate connector in a tube shape, wherein the first support plate and the second support plate are respectively fixedly arranged on the outer circumferential surfaces at both ends of the support plate connector, and the spray head is arranged on the outer side of the first support plate; The blowing unit includes fan blades and a blowing transmission structure for providing power to the fan blades.

[0019] Furthermore, the partition net is a mesh structure; Alternatively, the partition net is a mesh structure composed of one or more annular rods and strip rods. When there are multiple annular rods, the multiple annular rods have different diameters and are fixedly arranged on the strip rods. The strip rods are fixedly connected to the second support plate. A mesh hole is provided in the middle of the mesh so that the fourth transmission shaft can pass through.

[0020] Furthermore, at least one of the nozzles is disposed at the edge of the first support plate, and the nozzles are disposed circumferentially or non-circumferentially, uniformly or non-uniformly on the first support plate; When the arrangement is non-circumferential, a guard plate is arranged between the first support plate and the baffle plate.

[0021] By adopting the above-mentioned further scheme, evenly distributed nozzles can ensure that the area is evenly covered with water, and non-uniformly distributed nozzles can be customized according to crop growth needs or terrain characteristics to optimize the utilization of water resources; at the same time, when the first support plate is placed vertically on the ground, the guard plate can prevent the high-pressure water mist sprayed by the nozzle from damaging the green plants at the bottom of the spray frame, and prevent the soil splashed from the ground from entering the interior of the spray frame, while preventing the airflow generated by the blowing unit from escaping from the bottom of the spray frame, affecting the diffusion effect of the water mist.

[0022] Furthermore, the support plate connector is a cylindrical, cubic or triangular prism-shaped tube.

[0023] Furthermore, the baffle is a plane baffle or a curved baffle, and the center of the curved baffle is concave in a direction close to the first support plate or convex in a direction away from the first support plate.

[0024] By adopting the above-mentioned further scheme, when the baffle is a flat baffle, after the airflow hits the baffle, it will blow toward the nozzle along the spraying direction of the nozzle, so that the water mist can be blown to the surroundings more effectively, and the spraying range and height of the nozzle can be expanded; when the baffle is a curved baffle, after the airflow hits the baffle, the gas flow direction will be at a certain angle to the spraying direction of the nozzle, so that the water mist can be blown away more effectively, thereby improving the uniformity of the nozzle spraying.

[0026] With the above further solution, the second frame can drive the spraying frame to rotate relative to the traveling system, i.e., the equipment, so as to adjust the spraying angle of the spraying component, and thus meet the needs of various actual spraying scenarios; and through the cooperation of the support plate and the support block, the spraying angle of the spraying component can be restricted, ensuring the stability during the operation of the spraying component and making the adjustment simple; at the same time, since the rotation axis of the first spraying transmission wheel is the same as the rotation axis of the second frame, even if the second frame drives the spraying component to rotate relative to the first frame, i.e., the traveling system, the first spraying transmission wheel can still transmit the power of the engine.

[0027] Further, one end of the second frame is rotationally connected to the first frame through a rotating component, and the rotation axis of the first spraying transmission wheel coincides with the rotation axis of the rotating component.

[0029] With the above further solution, two rotating components are respectively arranged on the two sides of the connecting frame body and have the same rotation axis, which helps to evenly disperse the force during rotation, reduce the single-point stress, and ensure the balance and stability of the spraying component during rotation.

[0030] Further, the second frame further includes an "L"-shaped second support frame body, a first strengthening frame body and a second strengthening frame body; One end of the second support frame body is fixedly connected to the first support frame body, and the other end is fixedly connected to the bottom of the spraying component; The first reinforcing frame is arranged on the connecting frame to improve the strength of the first supporting frame; One end of the second reinforcement frame is fixedly connected to the first reinforcement frame, and the other end is fixedly connected to the first support frame, so as to improve the overall strength of the second frame.

The water inlet of the water pump 31 is connected to an external water source, such as a well, a pond, etc., through a pipeline. Therefore, a long water pipe is provided at the water inlet of the water pump 31 to facilitate the connection between the water pump and the external water source. The water outlet of the water pump 31 is connected to the water inlet of the pressurized tank 32 through a pipeline, and the water outlet of the pressurized tank 32 is connected to the water inlet pipe 331 through a pipeline, so that the water in the well, pond, etc. is irrigated by the spray gun 33.

[0063] Furthermore, the water tank 5 is fixedly arranged on the frame 11, the transmission structure of the walking system is a gearbox 13, the intermediate transmission wheel 23 is fixedly connected to the input shaft of the gearbox 13, and the output end of the gearbox 13 is the rotation transmission power of the wheel 12; The water tank 5 is provided with a water inlet 51 at the top and a water discharge port 52 at the bottom.

[0065] In this embodiment, when in use, the motor is first started to assist the engine 21, i.e., the diesel engine, through the belt drive. The diesel engine transmits power to the intermediate transmission wheel 23 and the irrigation transmission wheel 24 through the main transmission wheel 22. The intermediate transmission wheel 23 transmits power to the gearbox 13 to drive the wheel 12 to rotate, thereby realizing the movement of the equipment. Since the irrigation transmission wheel 24 is rotatably arranged on the first transmission shaft 241, the irrigation system 3 will not work at this time; when it is necessary to irrigate the farmland or garden, the water pump 31 and the external water source (well, pond, etc.) are connected through a water pipe, and the spray gun 33 is removed and set up at the same time, and the water outlet of the pressurized tank 32 and the water inlet pipe 331 on the spray gun 33 are connected through a water pipe, and then the push rod is used to push the first push block to push the first card block into the first card slot, so that the irrigation transmission wheel 24 can transmit power to the water pump 31, thereby realizing irrigation.

[0066] While the intermediate transmission wheel 23 transmits power to the gearbox 13, it also transmits power to the spray transmission wheel 1 25 through belt transmission. The spray transmission wheel 1 25 transmits power to the spray transmission wheel 2 26 through belt transmission. Since the spray transmission wheel 1 25 and the spray transmission wheel 2 26 are rotatably arranged on the second transmission shaft 251 and the third transmission shaft 261 respectively, the fan blades 4111 and the high-pressure fluid delivery component 42, that is, the high-pressure pump, will not work at this time; similarly, when the fan blades 4111 and the high-pressure fluid delivery component 42 are required to work, the push rod is used to push the corresponding push block to push the corresponding card block into the corresponding card slot, so that the power can be transmitted to the fan blades and the high-pressure fluid delivery component 42, thereby realizing spraying.

[0067] When it is necessary to adjust the spraying angle of the spray assembly 41, first stop the spraying system 4, stabilize the spray frame 4121, disengage the adjustment slot 442 on the support plate 411 from the support block 443, rotate the spray frame 4121 to the required spraying angle, and lock the corresponding adjustment slot 442 and support block 443 to achieve the adjustment of the spraying angle of the spray assembly 41.
