[0002] A vehicle-mounted sprayer is a liquid spraying device installed on a motor vehicle. The pump body is driven by a power system to pressurize the liquid and then deliver it to the nozzle through pipelines. Relying on the mobility of the vehicle, the vehicle-mounted sprayer can quickly cover large areas such as farmland, highways, and mining areas. It is mainly used in mobile spraying operations such as agricultural plant protection and municipal sanitation. By using a vehicle-mounted sprayer, mechanized liquid spraying operations can be achieved.

[0003] To expand the spray coverage area, existing vehicle-mounted sprayers often adopt a structure that can rotate the nozzle angle. These rotating nozzles are composed of a single motor-driven worm gear mechanism, which can only adjust the pitch angle of the nozzle. The limited directional adjustment results in a large blind spot and restricts the adaptability and efficiency of the device. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a multi-directional rotating nozzle adjustment device for vehicle-mounted sprayers, which aims to improve the problem that the directional adjustment dimension of existing devices is relatively simple.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional rotating nozzle adjustment device for a vehicle-mounted sprayer, including a support base. A control box is installed on the left side of the inner wall of the support base. A base is fixedly connected to the top of the control box. A motor 1 and a motor 2 are fixedly connected to the right side of the base. A rotating frame 1 is rotatably connected to the left side of the base. A bevel gear shaft 1 is rotatably connected to both the front and rear sides of the rotating frame 1. A bevel gear shaft 2 is meshed with the left side of the bevel gear shaft 1. The bevel gear shaft 2 is rotatably connected to the rotating frame 1. A bracket is fixedly connected to the left end of the bevel gear shaft 2. A nozzle is fixedly connected to the top of the bracket. A water tank is installed on the right side of the inner wall of the support base.

[0006] Preferably, the stirring mechanism includes a turntable, which is rotatably connected to the top of the water tank. A rotating frame is fixedly connected to the bottom of the turntable. Gear shafts are fixedly connected to both ends of the rotating frame. A sliding shaft is meshed with the top of the gear shaft. A fast gear is fixedly connected to the surface of the sliding shaft. A transmission rocker arm is fixedly connected to the left side of the sliding shaft.

[0007] Preferably, a stirring rod is fixedly connected to the bottom end of the gear shaft, and the stirring rod is used to stir the solution inside the water tank.

[0008] Preferably, a transmission disc is fixedly installed at the output end of the first motor, and a transmission belt is rotatably connected between the first transmission disc and the first bevel gear shaft; a transmission disc is fixedly installed at the output end of the second motor, and a transmission belt is rotatably connected between the second transmission disc and the first rotating frame.

[0009] Preferably, a universal joint is rotatably connected between the water tank and the nozzle, and the universal joint is used to transport the solution inside the water tank.

By starting motor 1, the nozzle elevation angle is controlled to change. The nozzle angle is controlled by motor 2 and motor 1, so that the nozzle can rotate to the front, rear, left and top directions. This realizes the four-way rotation adjustment function of the nozzle, improves the spray coverage range when the nozzle is working, and makes the device suitable for different operation needs.

[0015] 2.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-6 One embodiment of this utility model is provided: (Refer to...) Figure 1-4 An embodiment of this utility model provides a multi-directional rotating nozzle adjustment device for a vehicle-mounted sprayer, including a support base 1. A control box 2 is installed on the left side of the inner wall of the support base 1. A base 3 is fixedly connected to the top of the control box 2. A motor 4 and a motor 7 are fixedly connected to the right side of the base 3. A rotating frame 9 is rotatably connected to the left side of the base 3. A bevel gear shaft 6 is rotatably connected to both the front and rear sides of the rotating frame 9. A bevel gear shaft 10 is meshed with the left side of the bevel gear shaft 6. The bevel gear shaft 10 is rotatably connected to the rotating frame 9. A bracket 11 is fixedly connected to the left end of the bevel gear shaft 10. A nozzle 12 is fixedly connected to the top of the bracket 11. A water tank 13 is installed on the right side of the inner wall of the support base 1. A stirring mechanism is provided on the top of the water tank 13. The stirring mechanism is used to stir the spray concentrate.

[0026] The support base 1 is used to fix the device inside the truck bed. When the device is in use, the bottom of the support base 1 is connected to the truck bed. When the rotating frame 9 rotates, the bevel gear shaft 10 rotates together. Since the left end of the bevel gear shaft 10 is fixed to the bracket 11, and the front end of the rotating frame 9 is rotatably connected to the front end of the bevel gear shaft 6, the rotating frame 9 drives the nozzle 12 to rotate around the bevel gear shaft 6. Since the bevel gear shaft 6 is meshed with the bevel gear shaft 10, the bevel gear shaft 6 can control the change of the nozzle 12's elevation angle. Thus, the nozzle 12's angle can be controlled by the bevel gear shaft 6 and the rotating frame 9, allowing the nozzle 12 to rotate to the front, rear, left, and top directions. This achieves the four-way rotation adjustment function of the nozzle 12, improves the spray coverage of the nozzle 12 during operation, and makes the device suitable for different operational needs.

[0027] Reference Figure 5 The stirring mechanism includes a turntable 14, which is rotatably connected to the top of the water tank 13. A rotating frame 16 is fixedly connected to the bottom of the turntable 14. Gear shafts 15 are fixedly connected to both the left and right ends of the rotating frame 16. A sliding shaft 17 is meshed with the top of the gear shaft 15. A fast gear 18 is fixedly connected to the surface of the sliding shaft 17. A transmission rocker arm 20 is fixedly connected to the left side of the sliding shaft 17.

[0028] When it is necessary to change the gear ratio, the sliding shaft 17 is moved upward by rotating the transmission rocker arm 20, so that the fast gear 18 meshes with the gear shaft 15, thereby changing the transmission ratio of the stirring mechanism. This allows the stirring mechanism to have both a manual stirring mechanism and a gear speed change function, reducing the power requirements of the device and adapting to the mixing requirements of solutions with different viscosities, thus improving the ease of operation of the device.

[0029] Reference Figure 4 A stirring rod 19 is fixedly connected to the bottom end of the gear shaft 15. The stirring rod 19 is used to stir the solution inside the water tank 13. When the water tank 13 needs to be used to stir the prepared solution, the bottom of the turntable 14 meshes with the gear shaft 15, so that when the turntable 14 is rotated, it drives the gear shaft 15 to rotate, thereby causing the stirring rod 19 connected to the bottom end of the gear shaft 15 to stir the solution stored inside the water tank 13.

[0030] Reference Figure 3A transmission disc 5 is fixedly installed at the output end of motor 4. A transmission belt rotatably connects transmission disc 5 and bevel gear shaft 6. A transmission disc 8 is fixedly installed at the output end of motor 7. A transmission belt rotatably connects transmission disc 8 and rotating frame 9. By starting motor 7, transmission disc 8 starts to rotate. Under the action of the transmission belt, rotating frame 9 rotates simultaneously, thereby driving bevel gear shaft 10 to rotate. By starting motor 4, transmission disc 5 controls bevel gear shaft 6 to rotate via the transmission belt. Since bevel gear shaft 6 and bevel gear shaft 10 are meshed, motor 4 can control the elevation angle of nozzle 12, thereby realizing the joint control of nozzle 12 angle by starting motor 4 and motor 7.

[0031] Reference Figure 1 A universal tube is rotatably connected between the water tank 13 and the nozzle 12. The universal tube is used to transport the solution inside the water tank 13. The universal tube can ensure that the liquid is transported without obstruction when the nozzle 12 rotates in four directions. The universal tube is covered with a polyurethane protective layer, which can alleviate the mechanical wear and chemical corrosion of the universal tube.

[0032] Reference Figure 1 The nozzle 12 is electrically connected to the control box 2. The control box 2 can control the nozzle 12 to start and control motor 4 and motor 7 to rotate the nozzle 12 according to the working requirements, thereby realizing intelligent control of the nozzle 12.

[0033] Reference Figure 1 The transmission rocker arm 20 is rotatably connected to the top of the water tank 13, the inner wall of the sliding shaft 17 is slidably connected to the top of the water tank 13, and the fast gear 18 is meshed with the bottom end of the gear shaft 15. When the sliding shaft 17 is meshed with the gear shaft 15, it is in the low speed position, which can reduce the stirring speed and increase the torque, and is suitable for the thorough mixing of high viscosity or easily crystallizing agents. When the fast gear 18 is meshed with the gear shaft 15, it is in the high speed position, which can increase the stirring speed and accelerate the uniform distribution of low viscosity solutions.

[0034] Reference Figure 2 The nozzle 12 is equipped with an axial flow fan, which is used to generate high-speed airflow. The axial flow fan has the characteristics of large air volume and wide coverage. The high-speed airflow generated by the axial flow fan can atomize and diffuse the incoming spray liquid.

[0035] Working principle: When the angle of the nozzle 12 needs to be adjusted, the motor 27 is started to make the transmission disc 28 start to rotate. Under the action of the transmission belt, the rotating frame 19 rotates at the same time, thereby driving the bevel gear shaft 20 to rotate. Since the left end of the bevel gear shaft 20 is fixed to the bracket 11, and the front end of the rotating frame 19 is rotatably connected to the front end of the bevel gear shaft 6, the rotating frame 19 drives the nozzle 12 to rotate around the bevel gear shaft 6 when it rotates.

[0036] The start-up motor 4 causes the transmission disc 5 to control the rotation of the bevel gear shaft 6 via the conveyor belt. Since the bevel gear shaft 6 is meshed with the bevel gear shaft 10, the motor 4 can control the elevation angle of the nozzle 12. Thus, the nozzle 12 can be rotated to the front, rear, left, and top directions by the joint control of the motor 7 and the motor 4. This achieves the four-way rotation adjustment function of the nozzle 12, improves the spray coverage of the nozzle 12 during operation, and makes the device suitable for different operational needs.

[0037] In terms of preparing the spray concentrate, when it is necessary to use the water tank 13 to stir the prepared solution, the bottom of the turntable 14 is engaged with the gear shaft 15, so that rotating the turntable 14 drives the gear shaft 15 to rotate, thereby causing the stirring rod 19 connected to the bottom of the gear shaft 15 to stir the solution stored inside the water tank 13.

[0038] When it is necessary to change the gear ratio, the sliding shaft 17 is moved upward by rotating the transmission rocker arm 20, so that the fast gear 18 meshes with the gear shaft 15, thereby changing the transmission ratio of the stirring mechanism. This allows the stirring mechanism to have both a manual stirring mechanism and a gear speed change function, reducing the power requirements of the device and adapting to the mixing requirements of solutions with different viscosities, thus improving the ease of operation of the device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
