Description

Technical Field

[0001] The utility model relates to the field of special equipment for greening in urban construction, in particular to a multifunctional urban greening spraying vehicle. Background Art

[0002] Urban road greening and garden greening are important components of modern urban construction. With the development of social economy, the scientific and technological level of urban greening in my country has been continuously improved. Various greening spraying devices are widely used in the daily maintenance and beautification of urban garden greening. Among them, sprinkler devices and tree whitening spraying devices are the most demanded and widely used spraying devices in current garden greening operations.

[0003] Sprinklers are primarily used to meet the irrigation needs of landscaping, primarily targeting lawns and low shrubs. Traditional sprinklers fall into the following categories: Backpack manual sprinklers, which require landscaping workers to carry a water tank and manually squeeze out the spray. These sprinklers lack automatic nozzle angle adjustment, are inefficient, and require significant human resources; fixed landscaping sprinklers, which offer timed and quantitative irrigation, but have a fixed irrigation area and high piping costs; and landscaping fog cannons, which can cover large areas but have low water resource utilization and can interfere with pedestrians around the vehicle during spraying.

[0004] Whitewash spraying devices are primarily used for whitewashing trees. Whitewashing can help prevent pests and diseases, as well as frost cracking of tree trunks, and is a common practice in landscaping and landscaping. Currently, whitewashing in China is primarily done manually, but the whitewash's primary ingredient is limewater, which releases molecules that can be harmful to workers' eyes and skin.

[0005] Based on the above functional requirements, many scholars have proposed more automated alternatives to the above devices, using automation technology to achieve spray irrigation of plants in green belts or automated whitewashing of trees. Although the existing sprinkler irrigation devices and whitewashing devices have achieved a certain degree of automation, there are few composite devices that comprehensively consider these two functions. Moreover, most of the existing equipment still requires one-on-one operation by operators during use and cannot intelligently identify the operation targets. Therefore, it is necessary to improve and integrate the existing automated equipment, and integrate these two most common devices in landscaping operations into a system to facilitate greening operations.

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] A multifunctional urban greening spraying vehicle, such as Figure 1-6 As shown, it can realize multiple functions such as lawn irrigation and tree trunk whitewashing during the journey. The utility model will be specifically described below through this embodiment. The multifunctional urban greening spraying vehicle includes a vehicle body 1 and a spraying system installed on the vehicle body 1. The spraying system includes a sprinkler device 2, a whitewashing spraying device 3, a liquid storage tank 4 and a conveying system 5. The sprinkler device 2 is used to realize multi-angle lawn irrigation, and the whitewashing spraying device 3 is used for tree trunk whitewashing operations. The liquid storage tank 4 is used to store irrigation water and liquid for tree trunk whitewashing. The conveying system 5 connects the sprinkler device 2 and the whitewashing spraying device 3 to the liquid storage tank 4 respectively, so as to realize uninterrupted supply of corresponding liquids to different devices. In order to realize multi-angle irrigation of the lawn, the sprinkler device 2 includes a long first spray body 201 with adjustable pitch angle, the nozzle of the first spray body 201 is downward and the two ends of the first spray body 201 are provided with distance measuring devices 202; and the whitewashing spray device 3 includes a plurality of second spray bodies 301 arranged in a ring-shaped manner, the nozzles of the second spray bodies 301 are horizontally facing the center point of the ring, and the whitewashing spray device 3 is also equipped with a visual capture device, such as a camera, etc. The camera can be used to identify the color of the tree trunk, realize the intelligent whitewashing of the tree trunk in a ring-shaped manner, and further record the on-site working conditions to determine the operating status of the system. When in use, by adjusting the position of the whitewashing spray device 3, the tree trunk to be whitewashed is located at the center point of the second spray body 301, and starting the whitewashing spray device 3, the whitewashing liquid can be evenly sprayed on the surface of the tree trunk to achieve the effect of preventing diseases and pests. The sprinkler system 2, whitewash spraying device 3, liquid storage tank 4, and delivery system 5 are mounted on the vehicle body 1 via a vehicle-mounted platform 6. This platform 6 allows for the entire spraying system to be assembled and disassembled, making it adaptable to a variety of trucks and more convenient and quick to assemble and disassemble. As the vehicle moves, the entire spraying system moves forward, and upon reaching the desired location, the system activates and begins operation. This improves the efficiency of urban greening operations, saves labor costs, and reduces injuries to workers during whitewashing or sprinkler irrigation.

[0034] The liquid storage tank 4 is partitioned according to the specific needs of the landscaping operation, and a buffer baffle 41 is installed within the tank. Specifically, in this embodiment, the tank 4 can be divided into two independent compartments, one for whitewashing liquid and the other for irrigation water. The partition ratio can be allocated based on the frequency of different functional applications. Based on the actual business of urban greening, the tank 4 is divided into a larger first chamber 46 and a smaller second chamber 47. Furthermore, each compartment of the tank 4 can be equipped with a buffer baffle 41. The buffer baffle 41 has a through hole near the bottom to prevent the flow of liquid within the different compartments separated by the buffer baffle 41. At the same time, the buffer baffle 41 effectively reduces the impact of the liquid in the tank caused by the shaking of the vehicle during transportation. The top of the tank 4 is equipped with a liquid inlet 42 for filling the tank with clean water or whitewashing liquid. A filter 43 can also be installed at the liquid inlet 42 to prevent foreign matter from entering the tank during liquid filling. An electric pump 44 is provided at the bottom of the liquid storage tank 4. This electric pump 44 is connected to a delivery system 5 and is responsible for pumping the various liquids within the liquid storage tank 4 into the delivery system 5 for delivery to various work terminals. Furthermore, the liquid storage tank 4 may also be provided with a water level gauge 45 for detecting the amount of liquid remaining within the tank. This gauge utilizes the principle of communicating vessels, with each partition of the liquid storage tank 4 being connected to a transparent vertical tube. The vertical tube communicates with the interior of each partition, allowing for easy viewing of the remaining liquid within the tank. Furthermore, through the introduction of circuitry, a water level gauge based on electrical signals may also be employed. The specific structure of the water level gauge is well known to those skilled in the art and will not be elaborated upon here.

[0035] The delivery system 5 includes a first pipeline 51 connected to the sprinkler device 2 and a second pipeline 52 connected to the whitewash spray device 3. The first chamber 46 of the liquid storage tank 4 is connected to the first pipeline 51 and is filled with clean water for spraying lawns and bushes. The second chamber 47 is connected to the second pipeline 52 and is filled with whitewashing liquid for whitewashing tree trunks. The liquid outlet end of the second pipeline 52 is divided into multiple groups of outlets and is respectively connected to a second spray body 301, thereby enabling the whitewash spray device to spray whitewashing liquid from different angles toward the tree trunks surrounding the center. The whitewash spray device 3 is generally provided with at least three second spray bodies 301, which can form an enclosed position to spray whitewash on the tree trunks. In this embodiment, the whitewash spray device 3 is provided with at least four second spray bodies 301, and at least two second spray bodies 301 are connected in series to form a support arm and connected to a group of outlets of the second pipeline 52. The angle between the second spray bodies 301 forming the same support arm is adjustable. The conveying system 5 is equipped with multiple opening and closing devices and flow control devices to control the flow of the pipeline. These opening and closing devices can be ball valves or other electronic valves. The ball valve structure mainly consists of a valve body, a ball, a valve stem, and a seal. The valve body is the main body of the ball valve, with a spherical hole inside, within which the ball rotates. When the ball rotates parallel to the valve body orifice, water can flow through, thereby controlling the flow and flow rate. The valve stem controls the rotation of the ball. By rotating the valve stem, the angle of rotation of the ball is controlled, thereby controlling the flow rate and direction of the water flow. The opening of the ball valve can be adjusted by rotating the ball valve handle to control the water flow rate. When the ball is rotated parallel to the valve body orifice, the water flow rate is maximum; when the ball is rotated perpendicular to the valve body orifice, the water flow rate is minimum. By rotating the ball, the water flow rate can be precisely controlled to meet different water output requirements. The electronic valve can be a solenoid valve, or even a solenoid valve with multiple opening and closing levels.

[0036] The first pipeline 51 is connected to the sprinkler device 2 to achieve multi-angle sprinkler irrigation of the lawn. Specifically, the sprinkler device 2 is provided with at least two distance measuring devices 202, which are arranged at both ends of the first spraying body 201. The two distance measuring devices 202 detect the distance between the lawn to be sprinkled and determine the current angle between the spraying body and the lawn, and then adjust the spraying angle of the sprinkler device 2 to achieve multi-angle sprinkler irrigation of the lawn. Furthermore, the sprinkler device 2 can adopt a two-stage folding structure. Specifically, it can include a first protective shell 203 and a first spraying body 201 hinged to the first protective shell 203. One end of the first spraying body 201 is rotatably hinged to one end of the first protective shell 203. The rotation axis is horizontal and perpendicular to the first protective shell 203, and the first spraying body 201 can swing up and down around the rotation axis. The first protective shell 203 is a U-shaped steel structure with an opening facing upward. The first control motor 207 is fixedly installed on the outer side surface of one end connected to the first spray body 201. The output shaft of the first control motor 207 passes through the side wall of the first protective shell 203 and is fixedly installed on the outer shell of the first spray body 201. The first control motor 207 controls the first spray body 201 to swing up and down. The second end of the first protective shell 203 away from the first spray body 201 is hinged on the vehicle-mounted platform 6. Specifically, a first vertical fixed rod 205 is installed on the vehicle-mounted platform 6. A U-shaped connector 206 with an outward opening is fixed to the upper end of the first vertical fixed rod 205. The second end of the first protective shell 203 is a closed square tubular structure, which is hinged on the U-shaped connector 206. The rotating shaft is vertically arranged, and the first protective shell 203 swings in the horizontal plane. The upper surface of the U-shaped connector 206 is fixedly installed with a second control motor 204. The output shaft of the second control motor 204 penetrates the upper blade of the U-shaped connector 206 and is fixedly installed on the second end of the first protective shell 203. The second control motor 204 controls the first protective shell 203 to swing in the horizontal plane. When not in operation, the first spraying body 201 rotates upward 180° and then embeds into the first protective shell 203 from top to bottom. The first protective shell 203 drives the first spraying body 201 to rotate horizontally 90° and then abut against the vehicle-mounted platform 6. The vehicle-mounted platform 6 may further be provided with a first protective groove 208, into which the first protective shell 203 hides when abutting against the vehicle-mounted platform 6. Furthermore, the sprinkler device is mounted on the vehicle-mounted platform via a height adjuster. Specifically, the first protective shell can be mounted on the first vertical fixed rod via an upper and lower slider. The upper and lower sliders slide on the first vertical fixed rod to adjust the upper and lower positions of the first spraying body. In this embodiment, the first spraying body does not have the function of moving up and down, and this will not be described in detail here.A first limit block 209 for limiting the rotation angle of the first spray body 201 can also be provided between the first spray body 201 and the first protective shell 203. The first limit block 209 can ensure that the first spray body 201 reaches the designated position as soon as possible when it is opened, and the first control motor 207 stops working in time after sensing the corresponding blocking pressure to avoid motor burnout. A first camera can be provided at the connection between the first protective shell 203 and the first spray body 201. The greening and clearing of the surrounding roads can be observed through the image fed back by the first camera, and then targeted greening maintenance operations can be carried out. The first camera is not shown in the drawings of this embodiment. The distance measuring devices 202 at both ends of the first spray body 201 can be infrared distance measuring sensors or ultrasonic sensors, which determine the distance between the distance measuring device 202 and the surface to be sprayed by capturing the reflected signal. Taking the sprinkler irrigation lawn as an example, when the equipment is working, the distances from the two ends of the first sprinkler body 201 to the lawn measured by the two distance measuring devices 202 can be compared first. When the values detected by the two distance measuring devices 202 differ greatly, the pitch angle of the first sprinkler body 201 can be adjusted by the first control motor 207. Only when the difference between the two distance measuring devices 202 is within 10%, it is confirmed that the sprinkler device 2 is parallel to the lawn at this time, and the sprinkler irrigation effect is best at this time. The first sprinkler body 201 is started to start irrigating the lawn. The first pipeline 51 includes a first hard tube 511 fixedly mounted on the first vertical fixing rod 205 and a first hose 512 connected to the first spray body 201. The first hard tube 511 is close to the rear of the first vertical fixing rod 205, and the lower end is connected to the liquid storage tank 4 and obtains clean water supply from the liquid storage tank 4. The upper end passes through the upper end of the first vertical fixing rod 205 and is connected to the first hose 512. After the first hose 512 passes through the second end of the first protective shell 203, it is connected to the liquid inlet on the other side of the first spray body 201 opposite to the plane where the nozzle is located through the internal groove of the first protective shell 203, so as to introduce clean water into the first spray body 201.

[0037] The second pipeline 52 is connected to the whitewash spraying device 3 to whitewash the tree trunk. In this embodiment, the second pipeline 52 connects the two arms, enabling the two arms to perform a circumferential whitewash spraying of the tree trunk. Specifically, the whitewash spraying device 3 is equipped with four second spraying bodies 301. Each two second spraying bodies 301 are connected in series to form a branch arm and connected to a set of outlets of the second pipeline 52. The angles between the second spraying bodies 301 that make up the branch arm are adjustable. The whitewash spraying device 3 adopts a symmetrical three-section folding structure, which respectively comprises a second protective shell 303, a main spray gun 304, and an auxiliary spray gun 305. The whitewash spray device is mounted on a vehicle-mounted platform 6 via a height adjuster. Specifically, the vehicle-mounted platform 6 is equipped with two adjacent and parallel vertical fixing rods 306 and 307. Each rod 306 and 307 is provided with a mounting bracket 308 that can slide vertically. The second protective shells 303 of the two arms are pivotally hinged to their corresponding mounting brackets 308 at one end, allowing them to move vertically with the mounting brackets 308. The following details only one arm; the other arm is a mirror image and is not described here. The second vertical fixing rod 306 and the third vertical fixing rod 307 are hollow structures, and a vertical screw rod is rotatably installed inside them. At the same time, a vertical slot is provided on the vertical fixing rod. The mounting seat 308 is a slider that is sleeved on the vertical screw rod, and a thread that cooperates with the vertical screw rod is provided inside the slider. The mounting seat 308 protrudes from the vertical slot to the vertical fixing rod for connecting to the second protective shell 303. Since the mounting seat 308 is provided with a circumferential limit on the horizontal plane, when the vertical screw rod rotates, the mounting seat 308 will slide up and down on the vertical screw rod due to the limiting effect, and the rotation of the vertical screw rod is realized by the third control motor 310. A second U-shaped connecting piece 311 with an opening facing outward is fixedly installed on the slider. The second protective shell 303 adopts a U-shaped steel structure. The openings of the two second protective shells 303 are horizontally facing the two outer sides of the second vertical fixed rod 306 and the third vertical fixed rod 307 respectively. The second protective shells 303 are respectively hinged on the second U-shaped connecting piece 311 on their respective vertical fixed rods, and the rotating shaft is vertically arranged. The two second protective shells 303 can swing to both sides of the vertical fixed rod in the horizontal plane and close to the vehicle-mounted platform 6. The rotation of the second protective shell 303 is controlled by the sixth control motor 317. The other end of the second protective shell 303 away from the second U-shaped connecting piece 311 is hinged with a main spray gun 304. The nozzle of the main spray gun 304 is horizontally facing the inner side of the two vertical fixed rods and one end is hinged in the U-shaped groove of the second protective shell 303 and is controlled by the fourth control motor 312. It can swing in the horizontal plane and be embedded in the second protective shell 303 as a whole. The fourth control motor 312 is fixedly installed on the upper end face of the second protective shell 303, and the output shaft penetrates the upper surface of the second protective shell 303 and is fixedly installed on the outer shell of the main spray gun 304.The other end of the main spray gun 304 is hinged to the auxiliary spray gun 305. The other end of the main spray gun 304 away from the second protective shell 303 is fixedly installed with a main and auxiliary connecting member 313. The main and auxiliary connecting member 313 is also a U-shaped steel structure. One end of the auxiliary spray gun 305 is embedded in the groove hinged to the main and auxiliary connecting member 313, and the rotating shaft is vertically arranged. The nozzle of the auxiliary spray gun 305 is also horizontally facing the inside of the two vertical fixed rods, and swings in the horizontal plane and merges with the nozzle of the main spray gun 304. The rotation of the auxiliary spray gun 305 is realized by the fifth control motor 314. The fifth control motor 314 is fixedly mounted on the upper surface of the main and auxiliary connecting member 313, and its output shaft penetrates the upper surface of the main and auxiliary connecting member 313 and is fixed to the end of the auxiliary spray gun 305. When not in operation, after the auxiliary spray gun 305 folds toward the main spray gun 304, the two are folded together toward the second protective shell 303 and simultaneously embedded in the groove of the second protective shell 303. As the second protective shell 303 swings toward the vehicle-mounted platform 6, the vehicle-mounted platform 6 is further provided with a second protective groove 315 for the two second protective shells 303. When the second protective shells 303 are close to the vehicle-mounted platform 6, they are hidden in the second protective groove 315. The three-stage folding structure can be folded and stowed to greatly reduce the space occupied by the whitewash spray device 3. The adjacent folding angles between the second protective shell 303, the main spray gun 304, and the auxiliary spray gun 305 are generally controlled within 180°. Furthermore, a limit block can be set on the main spray gun 304 and the auxiliary spray gun 305. The limit block can ensure that the main spray gun 304 or the auxiliary spray gun 305 reaches the designated position as soon as possible when it is opened, and the corresponding control motor stops working in time after sensing the corresponding blocking pressure to avoid motor burning. In addition, a second camera 316 can be provided on the second protective shell 303, the main spray gun 304 or the auxiliary spray gun 305. The second camera 316 is used to check the status of the whitewashing of the tree trunk and confirm the position of the tree trunk. In this embodiment, a second camera 316 is provided at the connection between the second protective shell 303 and the main spray gun 304 of the two arms. During the whitewashing operation, the vehicle moves forward at a slow speed, the second protective shell 303 is close to the vehicle-mounted platform 6, and the second camera 316 is in operation. When the second camera 316 recognizes the tree trunk and is located in the middle of the two second cameras 316, the vehicle brakes and prepares to perform the whitewashing operation. After the three-fold structure is unfolded, the second protective shell 303 and the main spray gun 304 form an angle of 135°, the main spray gun 304 and the auxiliary spray gun 305 form an angle of 90°, and the two second protective shells 303 remain parallel, so that the two main spray guns 304 and the two auxiliary spray guns 305 enclose to form a square. By capturing the tree trunk scene with the second camera 316 and adjusting the vehicle's position, the tree trunk is positioned at the center of the square enclosed by the four spray guns. Once the main spray gun 304 and auxiliary spray gun 305 have reached the appropriate position, the whitewashing agent begins to be sprayed on the tree trunk. During the spraying process, the whitewashing height can be adjusted by moving the mounting bracket 308 up and down. The height of the whitewashing mechanism can also be determined based on the image displayed by the second camera 316.When the second camera 316 detects that the white coverage of the whitened area reaches a certain level, the main spray gun 304 and the auxiliary spray gun 305 cease spraying. Once the coating is complete, the main spray gun 304 and the auxiliary spray gun 305 fold back, and the vehicle starts and continues driving until the second camera 316 detects the next tree trunk. The second pipeline 52 comprises a second rigid tube 521 fixedly mounted between the second vertical fixing rod 306 and the third vertical fixing rod 307, a second hose 522 connected to the main spray gun 304, and a third hose 523 between the main spray gun 304 and the auxiliary spray gun 305. The lower end of the second rigid tube 521 is connected to the liquid storage tank 4, where it receives a supply of whitening liquid. The upper end of the second rigid tube 521 forks into two outlets, each of which passes through the top of a vertical fixing rod and connects to its own second hose 522. The second hose 522 directs the whitening liquid into the interior of the second spray body 301 through the third hose 523, thus providing the whitening liquid supply. Furthermore, the structure connecting the sprinkler and whitewash spray devices to the vehicle-mounted platform can be horizontally movable. Specifically, a horizontal propulsion regulator can be added to the bottom of each vertical fixed rod. By driving the vertical fixed rod, the corresponding spray body can be horizontally movable along with the protective shell to accommodate various green belt specifications. The implementation of this translation is well known to those skilled in the art and will not be described in detail in this embodiment. In addition, a protective baffle can be installed on the device to prevent paint leakage and the impact on passers-by and operators.
