[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Some existing greening sprinkler trucks are equipped with multiple sets of nozzles, placed on both sides and the rear of the vehicle. By spraying from different positions, they can spray green plants in different directions. However, different nozzles require different watering methods, making the switching process cumbersome. It usually requires manual adjustment of valves or replacement of pipe connections, which is complex and time-consuming, making it difficult to quickly adapt to the needs of different greening scenarios and reducing the efficiency of roadside greening.

[0006] Therefore, this utility model provides a greening spraying vehicle that facilitates switching of irrigation methods. Utility Model Content

[0007] To address the problem that existing greening sprinkler trucks typically have nozzles fixed to the sides or rear of the vehicle, which can achieve different watering effects but involve a cumbersome switching process, the purpose of this utility model is to provide a greening sprinkler truck that facilitates switching between watering methods.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a greening sprayer vehicle that facilitates switching irrigation methods, comprising a greening sprayer vehicle body, wherein an irrigation mechanism is provided on one side of the greening sprayer vehicle body for adjusting the orientation of the spraying device, the irrigation mechanism comprising:

[0009] The conversion assembly includes an outer shell located on one side of the greening sprayer vehicle body. Two symmetrically distributed rotating frames are rotatably mounted on the upper part of the outer shell. A servo motor is fixedly mounted in the middle of the outer shell. A drive gear is rotatably mounted in the middle of the outer shell. The top of the drive gear is fixedly mounted on the drive end of the servo motor.

The bottom end of one of the rotating frames is fixedly mounted on the top middle of the driven gear. A fixed shell is fixedly mounted on one side of both rotating frames.

[0010] The adjustment component, located in the middle of the fixed housing, is used to adjust and control the spraying range.

[0011] Preferably, the adjustment assembly includes a screw rotatably mounted in the middle of the fixed housing. Multiple equally spaced movable frames are slidably mounted in the middle of the fixed housing. One movable frame is threaded onto the upper part of the screw. A connecting rod is rotatably mounted at the bottom end of each of the multiple movable frames. The ends of the multiple connecting rods away from the movable frames are rotatably mounted relative to each other. One side of one connecting rod is rotatably mounted on the lower part of the fixed housing. A mounting plate is fixedly mounted on one side of each of the multiple movable frames. A drive assembly is provided at the end of the screw that passes through the fixed housing.

[0012] Preferably, a triangular transmission belt is rotatably mounted on the lower part of the outer casing, and the rotating frame and the drive gear are connected by the triangular transmission belt.

[0016] This utility model provides a greening sprayer truck that facilitates switching between irrigation methods. Compared with the prior art, it has the following advantages:

[0017] 1. This application uses a servo motor to drive the active gear to rotate, and utilizes the meshing transmission between the active and driven gears, as well as the coaxial connection between the triangular transmission belt and the active gear, to enable the two rotating frames to rotate synchronously in opposite directions, thereby achieving the adjustment of the spray head's orientation. When it is necessary to irrigate both sides of the road green belt, the spray head is aligned with the target area under the drive of the servo motor, thus enabling quick switching between multiple irrigation modes such as single-side spraying, double-side spraying, and rear spraying, effectively avoiding the problem of the irrigation equipment being unable to be flexibly adjusted due to the fixed position spraying of traditional spray trucks.

[0018] 2. This application uses a stepper motor to drive the screw to rotate, and through the mutual coordination of the connecting rod and the moving block, it can achieve precise adjustment of the spray head spacing. When it is necessary to uniformly irrigate a large area of ​​lawn, the spray head spacing can be increased to achieve large-area coverage. When it is necessary to concentrate the irrigation of seedlings, the spacing can be reduced to increase the amount of water sprayed per unit area, so that it can flexibly switch between various operation modes such as large-area uniform spraying and fixed-point concentrated irrigation.

Detailed Implementation

[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] Please see Figure 1-4This utility model provides a technical solution: a greening sprayer truck that facilitates switching irrigation modes, comprising a greening sprayer truck body 1. The operator can control the servo motor 212 and stepper motor 222 via a human-machine interface installed inside the greening sprayer truck body 1 through a control system, thereby adjusting the spacing and position of the spray heads 227 to achieve different spraying effects. An irrigation mechanism 2 is provided on one side of the greening sprayer truck body 1 for adjusting the orientation of the spraying device. The irrigation mechanism 2 includes:

[0026] The conversion component 21 includes an outer shell 211 disposed on one side of the greening sprayer vehicle body 1. Two symmetrically distributed rotating frames 216 are rotatably mounted on the upper part of the outer shell 211. A servo motor 212 is fixedly mounted in the middle of the outer shell 211. The servo motor 212 can be an AC permanent magnet synchronous servo motor. The servo motor 212 is connected to the circuit through a dedicated servo driver. At the same time, the driver can be connected to the control system in the human-machine interface in the cab of the greening sprayer vehicle body 1 through a communication interface to receive motion commands and upload operating status data to achieve precise automated control. A drive gear 213 is rotatably mounted in the middle of the outer shell 211. The top of the drive gear 213 is fixedly mounted on the drive end of the servo motor 212. A driven gear 214 is rotatably mounted on one side of the inner side of the outer shell 211. The driven gear 214 meshes with the drive gear 213. The bottom end of one of the rotating frames 216 is fixedly mounted on the top middle of the driven gear 214. A fixed shell 221 is fixedly mounted on one side of both rotating frames 216.

[0027] Adjustment component 22 is located in the middle of fixed housing 221 and is used to adjust and control the spraying range.

[0028] The adjustment assembly 22 includes a screw 223 rotatably mounted in the middle of the fixed housing 221. Multiple equally spaced movable frames 224 are slidably mounted in the middle of the fixed housing 221. One of the movable frames 224 is threaded onto the upper part of the screw 223. A connecting rod 228 is rotatably mounted on the bottom end of each of the multiple movable frames 224. The ends of the multiple connecting rods 228 away from the movable frames 224 are rotatably mounted relative to each other. One side of one of the connecting rods 228 is rotatably mounted on the lower part of the fixed housing 221. A mounting plate 226 is fixedly mounted on one side of each of the multiple movable frames 224. A drive assembly is provided at one end of the screw 223 that passes through the fixed housing 221.

[0029] A triangular transmission belt 215 is rotatably mounted on the lower part of the outer casing 211. The rotating frame 216 and the drive gear 213 are connected by the triangular transmission belt 215. The triangular transmission belt 215 is used to achieve the purpose of synchronous and opposite rotation of the two rotating frames 216.

[0030] The drive assembly includes a stepper motor 222 fixedly mounted on one side of the fixed housing 221. One end of the screw 223, which passes through the fixed housing 221, is fixedly mounted on the drive end of the stepper motor 222. The stepper motor 222 can be a closed-loop stepper motor. The rotation angle of the screw 223 is fed back in real time through an encoder to achieve closed-loop control. Driven by the stepper motor 222, the screw 223 is rotated. Under the screw transmission, the end moving frame 224 produces linear displacement. Under the linkage of the connecting rod 228, multiple moving frames 224 move synchronously at the same speed to achieve the spacing adjustment of the spray head 227.

[0031] Each of the multiple movable frames 224 has a sliding block 225 fixedly installed at its top. The upper surface of the inner surface of the two fixed shells 221 is provided with a groove. The multiple sliding blocks 225 are slidably locked inside the groove. The groove has a T-shaped cross-section. The cross-section of the sliding block 225 is adapted to the groove, so that the sliding block 225 can slide stably inside the groove to limit the movement of the movable frame 224.

[0032] Spray heads 227 can be detachably installed on the upper part of multiple mounting plates 226. The spray heads 227 are connected to the water tank pipe of the greening spray truck body 1 through pipes. Water is drawn from the water tank by the water pumping equipment of the greening spray truck body 1 and sprayed out through the spray heads 227 under the transportation of the pipes. At the same time, under the control of the control system, it can achieve single-sided water supply and double-sided water supply effects.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, the servo motor 212 drives the drive gear 213 to rotate, which causes the driven gear 214 and the triangular transmission belt 215 to rotate synchronously and in opposite directions. This causes the two rotating frames 216 to deflect to both sides at the same time, thereby adjusting the position of the spray head 227. This allows for watering of both sides of the greening spray truck body 1 to achieve other effects.

[0035] Driven by the stepper motor 222, the screw 223 can be rotated. The moving frame 224 furthest from the stepper motor 222 is threadedly connected to the screw 223, while the screw 223 only slides through the middle of the other moving frames 224. When the screw 223 rotates, it can drive one of the moving frames 224 at the end to move. However, with the cooperation of the connecting rod 228, multiple moving frames 224 move simultaneously with the same distance between them, thereby adjusting the position of multiple spray heads 227 to achieve the effect of concentrated spraying and irrigation and large-area uniform spraying and irrigation.
