Description

Technical Field

[0001] This utility model relates to the field of sanitation equipment technology, specifically to a greening spraying vehicle with adjustable spraying angle. Background Technology

[0002] Sprinkler trucks, also known as multi-functional greening sprinkler trucks, are used for cleaning roads, sanitation, dust control, watering, and spraying pesticides in urban areas, large factories, military units, and parks to beautify the environment. The sprinkler trucks are equipped with duckbill nozzles or round nozzles at the front and cylindrical spray nozzles or showerhead nozzles at the rear for dust suppression and cooling. They can also be used for urban and rural landscaping and emergency firefighting.

[0003] Referring to the patent document: Patent Publication No. CN209359215U, Patent Publication Date 2019-09-10, a greening spraying vehicle is provided, including a vehicle body. A water storage tank is installed on the frame in the middle of the vehicle body. A spraying device is set on the working platform at the rear of the vehicle body. The spraying device includes a three-way pipe, a mist spraying device, and a column spraying device. A second water pump is installed in the tank. The column spraying device includes a second connecting water pipe, a column water spray hose, and a spray pipe support device. The tail end of the second connecting water pipe is connected to the outlet of the second water pump. This utility model has a mist spraying device and a column spraying device on the working platform. The size of the water mist sprayed by the mist spraying device can be adjusted by adjusting the speed of the first servo motor. The water mist pressure is achieved by the rotating mist spraying pipe, eliminating the need for water pump pressurization and extending the service life of the water pump. The working platform also has a column spraying device. During greening spraying, the operator can spray water in either column or mist form as needed, making it applicable to a wide range of occasions.

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

[0005] While existing greening spray trucks are equipped with angle adjustment devices, most of these devices have a small adjustment range, making it difficult to cover the spraying needs of special locations such as the tops of tall trees and low-lying ground cover plants. When maintaining vertical green landscapes or vegetation in complex terrain, they cannot achieve all-round and precise spraying. Furthermore, the adjustment mechanisms are mostly operated manually or semi-automatically, making the adjustment process cumbersome and time-consuming. This requires frequent manual adjustments, which not only reduces work efficiency but also increases labor costs.

[0006] Therefore, this utility model provides a greening spraying vehicle with an adjustable spraying angle. Utility Model Content

[0007] In order to solve the problems of the small range of the angle adjustment mechanism and the low degree of automation of existing greening spray trucks, the purpose of this utility model is to provide a greening spray truck with adjustable spray angle.

[0025] 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.

[0026] Please see Figure 1-4This utility model provides a technical solution: a greening spraying vehicle with adjustable spraying angle, including a greening spraying vehicle body 1, and an adjustment mechanism 2 on one side of the greening spraying vehicle body 1 for multi-angle adjustment of the spraying head. The adjustment mechanism 2 includes:

[0027] The execution component 21 includes a fixed shell 2171 located behind the main body 1 of the greening sprayer vehicle. A rotating frame 215 is rotatably mounted on the upper part of the fixed shell 2171. A deflection shaft 213 is rotatably mounted on the middle part of the rotating frame 215. A mounting frame 212 is fixedly mounted on the middle part of the deflection shaft 213. The end of the mounting frame 212 is provided with a quick-release clamp interface adapted to different specifications of spray heads, which is used to install and fix spray heads of different specifications. A deflection rod 214 is fixedly mounted on one side of the deflection shaft 213. A limiting ring 211 is provided on the upper part of the fixed shell 2171. A power component is provided on one side of the bottom end of the limiting ring 211. One side of the deflection rod 214 is slidably locked in the middle of the limiting ring 211. A groove is opened in the middle of the inner side of the limiting ring 211. One side of the deflection rod 214 is locked in the inside of the groove, so that it can drive the deflection rod 214 to rotate under the up and down movement of the limiting ring 211.

[0028] A fixed frame 216 is fixedly installed in the middle of the fixed housing 2171. A drive disk 218 is rotatably installed in the middle of one side of the fixed frame 216. A drive assembly is provided on one side of the drive disk 218. A drive rod 2181 is slidably attached to one side of the drive disk 218. A rotating shaft 219 is rotatably installed on one side of the fixed frame 216. A swing frame 2191 is fixedly installed on the upper part of the rotating shaft 219. One side of the drive rod 2181 is slidably sleeved on the outer surface of one side of the swing frame 2191. The bottom end of the rotating frame 215 is fixedly installed on the top end of the rotating shaft 219.

[0029] The horizontal adjustment component 22 is located at the lower part of the fixed housing 2171 and is used to adjust the horizontal angle of the spray head.

[0030] The leveling component 22 includes a driven gear 223 fixedly installed at the bottom of the fixed housing 2171. A driving gear 222 is provided on one side of the driven gear 223, and the driving gear 222 and the driven gear 223 are meshed with each other. A drive motor 221 is provided at the bottom of the driving gear 222. The bottom of the driving gear 222 is fixedly installed at the drive end of the drive motor 221. The drive motor 221 is a permanent magnet synchronous drive motor. The operator can precisely adjust the speed and direction of the motor through the angle target set by the vehicle terminal.

[0031] The drive assembly includes a servo motor 217, which is fixedly mounted on one side of the fixed housing 2171. The drive disk 218 is fixedly mounted on the drive end of the servo motor 217 at the center of one side. The servo motor 217 is a high-resolution, high-response-speed servo motor. The servo motor 217 supports multiple speed adjustment modes and can be flexibly switched through the vehicle control terminal to adjust the oscillation speed of the spray head.

[0032] The horizontal adjustment assembly 22 also includes a mounting shell 224 fixedly installed on the top of one side of the greening sprayer body 1. The lower part of the fixed shell 2171 is rotatably installed on the middle of the top of the mounting shell 224, and the drive motor 221 is fixedly installed on the inside side of the mounting shell 224.

[0033] The power assembly includes a cylinder 2111 fixedly mounted on one side of the top of the mounting housing 224. The cylinder 2111 is a standard cylinder with a high-strength aluminum alloy cylinder body and built-in wear-resistant sealing ring and precision guide sleeve. It can not only withstand greater pressure, but also reduce friction loss and extend service life. The cylinder 2111 can realize a wider range of spray head angle adjustment to meet the height requirements of different green areas. Whether it is low shrubs or tall trees, the spray angle can be precisely adjusted. At the same time, the extension stroke and speed of the cylinder 2111 can be controlled by the operator's vehicle control terminal to achieve stable and accurate positioning and avoid the spray head shaking due to excessive speed, which would affect the spraying effect. The bottom end of the limit ring 211 is fixedly mounted on the drive end of the cylinder 2111.

[0034] Multiple telescopic rods 2112 arranged in a ring array are fixedly installed on the top of the mounting shell 224. The bottom end of the limiting ring 211 is fixedly installed on the top end of the telescopic rod 2112. The telescopic rod 2112 includes an outer sleeve and an inner slide rod. The top end of the inner slide rod is fixed to the bottom end of the limiting ring 211 by a threaded connection. The bottom end of the outer sleeve is welded to the top of the mounting shell 224. The limiting ring 211 can be supported and limited by the telescopic rods 2112.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, when the angle of the spray head needs to be adjusted, the limit ring 211 can be driven by the cylinder 2111 to move downward, causing one side of the deflection rod 214 to move downward, which in turn drives the deflection shaft 213 to rotate, causing the mounting bracket 212 to swing backward, thereby adjusting the angle of the end of the spray head and raising the end of the spray head upward. When downward adjustment is needed, the cylinder 2111 can be tilted downward at the required angle to reverse the drive.

[0037] During irrigation, the servo motor 217 can be started to drive the drive disk 218 to rotate, which in turn drives the drive rod 2181, which is slidably mounted on one side of the drive disk 218, to rotate. Since one side of the drive rod 2181 is sleeved on one side of the swing frame 2191, the swing frame 2191 is driven to swing back and forth on one side under the rotation of the drive rod 2181, which drives the rotating shaft 219 to rotate back and forth. Under the transmission of the rotating frame 215, the spray head can swing back and forth left and right to spray during operation.

[0038] When it is necessary to adjust the horizontal direction of the spray head, the drive motor 221 can be started. Driven by the drive motor 221, the drive gear 222 will rotate, which will in turn drive the driven gear 223 to rotate, which will in turn drive the fixed shell 2171 to rotate, and then drive the spray head to rotate, so as to adjust the horizontal angle of the spray head and make it face different directions.
