The mobile spraying system 1 of the present invention is, for example, a mobile sprayer capable of spraying chemicals or water for controlling and / or controlling temperature and humidity on crops while automatically moving in a facility such as a greenhouse or a plastic house. The system includes a spreader 9, a moving body 72, and a guide portion 74.

As shown in FIG. 1, the spreader 9 stores the chemical liquid or water, and spreads the stored chemical liquid or water to the outside, and has a base plate 10.

It is. The base plate 10 is a circular plate body and is configured to be fixedly supported by the support body 73 of the moving body 72 to be described later.

In addition, the spreader 9 has a lift cylinder 12 installed in the center of the upper surface of the base plate 10. The lift cylinder 12 is a pneumatic cylinder operated by compressed air and has a cylinder housing 14 fixed upwardly to the base plate 10 and an operating rod 16 extending upward from the cylinder housing 14. Has In particular, the operation rod 16 is extended or contracted to the bottom by the compressed air introduced, the liquid storage tank 20 to be described later and the nozzle case 50 fixed to the liquid storage tank 20, the upper, By lifting up and down, it serves as a shanghai east to move the position of the fluid nozzle 60 to be described later up and down.

The liquid storage tank 20 is provided with a storage chamber 22 capable of storing the chemical liquid for controlling and / or feeding the nutrient solution, and an inlet 24 for introducing the chemical liquid into the storage chamber 22. Here, the inlet 24 is of course closed by the cap 26 to be selectively opened as needed. On the other hand, water is also stored in the storage chamber 22 of the liquid storage tank 20, in which case it is used to spray water with the sprayer 9 to control the temperature and humidity in the facility. Hereinafter, the spraying of the chemical liquid will be described as an example.

The liquid storage tank 20 is provided with a top water level sensor 28 and a bottom water level sensor 29 for detecting whether or not the chemical liquid is filled in the storage chamber 22 or exhausted. The upper water level sensor 28 and the lower water level sensor 29 are disposed at the upper and lower portions of the storage chamber 22.

It detects whether the level of the chemical liquid is above the set level or below the set level, and inputs the detected signal to the controller 120 of the controller 100 to be described later. Here, the controller 120 processes the signals input from the upper water level sensor 28 and the lower water level sensor 29 to determine whether the chemical liquid stored in the storage chamber 22 is full or exhausted, through a lamp or buzzer (not shown). Inform the user. At this time, the upper water level sensor 28, the lower water level sensor 29 and the controller 120 of the control unit 100 acts as a storage amount notification means for informing the storage amount of the chemical liquid.

The rotary motor 30 is fixedly installed on the operating rod 16 of the lift cylinder 12, and has an output shaft 32 fixedly supporting the liquid storage tank 20. The rotary motor 30 rotates the position of the fluid nozzle 60 by rotating the liquid storage tank 20 and the nozzle case 50 fixed thereto by the control of the controller 120 to be described later about a vertical axis. It acts as a rotating moving part.

Referring again to FIG. 1, the sparger 9 has a first ultrasonic generator for applying ultrasonic waves to the chemical liquid stored in the liquid storage tank 20. The first ultrasonic generator includes an ultrasonic oscillator 40 for generating a high frequency electric signal, and an ultrasonic vibrator 42 for generating ultrasonic waves in accordance with the generated electrical signal. In particular, the ultrasonic vibrator 42 is composed of a diaphragm 44 forming the bottom surface of the liquid storage tank 20, and a plurality of vibrators 46 fixed to the bottom surface of the diaphragm 44.

The first ultrasonic wave generator serves to stir the chemical liquid by applying the generated ultrasonic vibration energy to the liquid stored in the storage chamber 22. In particular, the ultrasonic wave is applied to the drug mass contained in the chemical liquid to serve to break the drug mass into small particles. Since the operation and configuration of the ultrasonic generator is already known, a detailed description thereof will be omitted.

In addition, referring to Figure 1, the sprayer 9 is a nozzle case 50 is fixedly installed on the upper surface of the liquid storage tank 20, a fluid nozzle 60 is fixed around the nozzle case 50, and the fluid An air compressor (70) for supplying high pressure compressed air to the nozzle (60) is provided. The nozzle case 50 is fixed to the upper surface of the liquid storage tank 20 through the support shaft 50a, and has an operating chamber 52. The nozzle case 50 is configured to rotate at the same time as the liquid storage tank 20 is rotated by the rotary motor (30). Here, the support shaft (50a) for supporting the nozzle case 50 is configured to be coaxial with the output shaft 32 of the rotary motor 30 for rotating the liquid storage tank 20, accordingly the nozzle case ( 50 is rotated about the same vertical axis as the liquid storage tank (20).

The fluid nozzle 60 is fixed to the circumference of the nozzle case 50 and has a nozzle body 62 as shown in FIG. 2. The nozzle body 62 has an internal flow path 64, which is a compressed air inlet 65 through which high-pressure compressed air can be introduced, and a fluid through which the introduced compressed air can be discharged. The nozzle hole 66 is provided. In addition, the internal flow path 64 is formed with a liquid introduction port 67 into which the chemical liquid can be introduced. Here, the compressed air inlet 65 is connected to the air compressor 70 through the connecting pipe (65a), the liquid inlet 67 is connected to the liquid storage tank (20) through the connecting pipe (67a). The fluid nozzle hole 66 is configured to face the outside of the nozzle case 50. The connecting tube 67a has an outer surface to prevent some of the chemicals remaining in the connecting tube 67a from freezing during the winter season so that the connecting tube 67a is blocked when the sprayer 9 is initially driven, thereby preventing malfunction. For example, it is preferable to wind up with the infrared heating tape 68.

The fluid nozzle 60 is operated by the air compressor 70 so that the high pressure compressed air is introduced into the compressed air inlet 65, and the compressed air introduced therethrough passes through the internal flow path 64, thereby providing a fluid nozzle hole 66. To discharge. Then, as the high pressure compressed air passes through the throat of the internal flow path 64, it is sucked up to the liquid inlet 67 by a siphon effect, and the chemical liquid of the sucked liquid storage tank 20 is compressed. Together with the fluid nozzle hole 66 to be atomized. As a result, the fluid nozzle 60 serves to spray small particles while sucking up the chemical liquid of the liquid storage tank 20. Here, the fluid nozzle 60 is a nozzle

As the case 50 rotates, the chemical liquid particles are evenly sprayed onto the planted crops while rotating simultaneously.

On the other hand, the nozzle 60 is provided with a second ultrasonic wave generator for applying ultrasonic waves to the chemical liquid discharged to the fluid nozzle hole 66. The second ultrasonic generator includes an ultrasonic oscillator 80 for generating a high frequency electric signal, and an ultrasonic vibrator 82 for generating ultrasonic waves in accordance with the generated electrical signal. In particular, the ultrasonic vibrator 82 passes through the vibrator 84 installed in the nozzle body 62 and the inner passage 64 of the nozzle body 62 to extend toward the fluid nozzle hole 66. 84) is provided with a horn 86 installed.

The second ultrasonic wave generator serves to further refine the chemical liquid by applying the generated ultrasonic vibration energy to the chemical liquid passing through the fluid nozzle hole 66. In particular, it is configured to apply ultrasonic waves to the drug scale and the solid component of the hydrating agent in the solidified chemical liquid attached to the periphery of the fluid nozzle hole 66, thereby crushing the scale and the hydrating solid component into small particles. This feature prevents the fluid nozzle hole 66 from clogging due to the scale of the drug attached to the fluid nozzle hole 66 and the solid component of the hydrating agent, and at the same time serves to maximize the mist efficiency.

Referring again to Figure 1, the spreader 9 is further provided with a blower for blowing the chemical liquid particles sprayed from the fluid nozzle 60 in the same direction as the spraying direction. The blower may be implemented by a blower fan 90 installed in the nozzle case 50 so that the blower may be disposed behind the fluid nozzle 60. The blowing fan 90 may move the chemical liquid particles sprayed from the fluid nozzle 60 to a farther place by blowing high-pressure air in the same direction as the spraying direction of the chemical liquid in the state disposed behind the fluid nozzle 60. At the same time, it can be spread to a wider place at the same time. On the other hand, the blowing fan 90 is configured to be installed in the operating chamber 52 of the nozzle case 50, so that the air blown to the inner wall 54 of the operating chamber 52 fluid from the operating chamber 52 The wire mesh 56 is installed to be discharged around the nozzle 60. Here, the blower fan 90 is configured to be controlled by the controller 120 of the controller 100, which will be described later. In this case, the inverter 120 converts the digital signal transmitted from the controller 120 into an analog signal and introduces the inverter. Of course, it has: 92).

As described above, even if the chemical liquid sprayed through the fluid nozzle 60 is diffused forward by the blower fan 90, a large portion of the chemical liquid sprayed by the air flow fan 90 is directly in front of the nozzle case 50. Will fall. However, since the spreader 9 of the present invention moves by the moving body 72 and the guide portion 74 as described below, no crops are placed at a predetermined distance from the spreader 9 in consideration of the movement of the spreader 9. It is not planted. Therefore, the chemical liquid falling directly in front of the nozzle case 50 is not only thrown away uselessly, but also keeps the water around the guide portion 74 at all times, causing damage to the electrical components of the mobile spraying system 1 after a long time. Can be.

In order to prevent such a problem, the spray guide to the front lower part of the nozzle case 50 to guide the chemical liquid sprayed through the fluid nozzle 60 to move forward and to not fall directly to the front of the nozzle case 50 directly. 69 is installed. The spray guide 69 is installed to extend forwardly from the bottom of the nozzle case 50, and is composed of a plate having fine vent holes to prevent the spray particles from tangling with each other even if the spray chemical liquid falls on it.

The moving body 72 supports and fixes the spreader 9 and moves the sprayer 9 to a position where the spreader 9 is sprayed. The movable body 72 includes a support body 73, a drive motor 78, and a power transmission unit 79.

The support body 73 is formed of a plate member having a rectangular shape. A plurality of wheels 76, for example, four wheels 76 are fixed to the lower side of the support body 73 so as to rotate. The wheels 76 form a set of two back and forth to share a rotation axis 76a, and both ends of the rotation shaft 76a of the front and rear (left and right in Fig. 2), respectively, a pair of front and rear, the lower side of the support body 73 It is rotatably supported by four support brackets 77 (shown one before and after the other) protruding at a predetermined interval from each other. These wheels 76 are formed so that the bottom surface is engaged with the guide rail 75 of the guide portion 74 to be described later to move over the guide rail (75). On the upper side of the support body 73, the base plate 10 of the spreader 9 is fixed as mentioned above, so that the spreader 8 is mounted and supported by the support body 73.

The drive motor 78 is installed adjacent to the rotation shaft 76a of the rear wheel 76 on one side, for example, the rear lower surface of the support body 73.

The power transmission unit 79 transmits the driving force of the driving motor 78 to the wheels 76, and the driving gear 78b formed on the driving shaft 78a of the driving motor 78 and the rotation shaft of the rear wheel 76. A driven gear 76b formed at 76a, and a power transmission gear 79a arranged to engage the drive gear 78b and the driven gear 76b. The shaft of the power transmission gear 79a is rotatably supported by a support (not shown) of the support body 73 between the drive gear 78b and the driven gear 76b.

Therefore, as the driving motor 78 is driven in the forward or reverse direction, the driving force of the driving motor 78 is transmitted to the rotation shaft 76a of the rear wheel 76 through the power transmission unit 79, and thus the rear wheel 76 ) Moves forward or backward on the guide rail 75 to move the support body 73 forward or backward.

As shown in Figure 3, the guide portion 74 is for guiding the movement of the support body 73 of the mobile body 72, the place to spray the chemical or water, that is, facilities such as greenhouses, plastic houses ( R) is installed in. The guide portion 74 is composed of a guide rail 75 for engaging the wheels 76 to guide the movement of the wheels 76. The guide rail 75 is formed in the shape of an elliptical caterpillar. However, the shape of the guide rail 75 is not limited to this, and may be configured in other forms such as a date form according to the form of the facility.

Referring again to FIG. 1, the mobile spraying system 1 of the present invention includes a plurality of regions 117 partitioned in a facility R such as a greenhouse, a plastic house, etc. in order to automatically control and / or control temperature and humidity. The driving motor 78 of the moving body 72 to move the moving object to a region requiring spraying according to the temperature and / or humidity of FIG. 3 to spray the chemical liquid or water to the required region through the fluid nozzle 60. And a control unit 100 for controlling the air compressor 70, the rotary motor 30, the lift cylinder 12, and the blower fan 90 of the spreader 9. The control unit 100 includes a sensor unit 10 having a plurality of temperature and / or humidity detecting sensors 110 installed in the plurality of regions 117 so as to sense temperature and / or humidity in the plurality of regions 117. And the temperature and / or humidity measured from the plurality of temperature and / or humidity detecting sensors 110 and the predetermined temperature and / or humidity are compared to the set temperature and / or humidity. The lower area is determined as the area to be sprayed, the moving body 72 is moved based on the determined area to be sprayed, and then the amount of chemicals, the direction of mist, the height of the mist and the width of the mist to the determined area to be sprayed are adjusted. Air compressor 70, rotary motor 30, lift cylinder 12, and blower fan 90 of moving body 72 and spreader 9 so as to spray the air through fluid nozzle 60. It is composed of a controller 120 for controlling).

Here, the temperature and / or humidity detection sensor for measuring the temperature and / or humidity as a reference for determining whether or not the spraying needs of each region 117 may be composed of only the humidity sensor when spraying the chemical liquid for control For temperature control such as cooling and cooling, it can be configured with only a temperature sensor. However, since both the use of both temperature and humidity at the time of control or temperature control can more accurately determine whether spraying is necessary, the temperature and / or humidity sensor 110 can measure both temperature and humidity below. And a humidity sensor will be described as an example.

In particular, the controller 120 includes an electronic circuit using a microprocessor, and is preset with input signals input from the temperature and humidity sensor 110 of each of the plurality of regions 117 to a memory (not shown). After comparing and determining the stored reference value, it is determined whether or not the spraying needs of each area 117 as the value is large or small with respect to the reference value, and if it is determined that the specific area is the spraying need area for spraying, the moving body 72 To control the air compressor 70, the rotary motor 30, the lift cylinder 12, and the blowing fan 90 of the driving motor 78 and the spreader 9 of the moving body 72 to move to a specific area The amount or distance of movement, the amount of mist of the chemical liquid in the required area of spraying, the direction of mist, the height of mist and the width of mist are adjusted. In this case, in order to prevent the chemical liquid from being excessively sprayed to a specific region, the controller 120 determines whether the spraying of each region 117 is necessary, and an input signal input from each temperature and humidity sensor 110. The spraying area with the chemical solution sprayed in the area where the spraying of chemicals was previously applied is smaller than the spraying area with chemical spraying in the surrounding area. It can be judged as the area to be sprayed. To this end, the controller 120 counts the number of times of spraying each time to spray the chemical liquid for each area 117 and stores in the memory.

In more detail, as shown in FIGS. 3 and 4, when each temperature and humidity sensor 110 measures the temperature and humidity of each region 117 (S1), the controller 120 measures the temperature and humidity. The input signals of the temperature and humidity sensors 110 corresponding to the measured temperature and humidity values of the respective regions 117, that is, the measured temperature and humidity values, are compared with the preset reference values of the temperature and humidity. The low region is searched (S2). At this time, if the temperature and humidity detected by the temperature and humidity sensor 110 in the '117a' area slightly away from the spreader 9 is lower than the temperature and humidity of the preset reference value, the controller 120 is first ' Area 117a 'is determined as the area to be sprayed. In addition, the controller 120 further determines whether the number of times the chemical liquid is sprayed previously is smaller than the number of times the chemical liquid has been previously sprayed in the front, rear, and left and right peripheral regions in the first spraying required region 117a. ). As a result of the determination, when the spraying frequency of the spraying area 117a is larger than the spraying frequency of the surrounding area, the controller 120 is an area in which spraying area 117a that is determined as primary is excessively sprayed with an excessive amount of chemical liquid and is unnecessary for spraying. After determining, the process returns to step S2 to compare the measured temperature and humidity values with the preset reference values of the temperature and humidity to continue searching for an area lower than the preset reference value.

If it is determined in step S3 that the spraying frequency of the spraying area 117a is smaller than the spraying frequency of the surrounding area, the controller 120 sprays the chemically excessive spraying area of the spraying area 117a that is determined as primary. It is judged as an area that needs to be sprayed.

Next, the controller 120 controls the drive motor 78 of the moving body 72 and the air compressor 70 of the spreader 9, the rotary motor 30, the lift cylinder 12, and the blower fan 90. Then, the moving body 72 is moved to the required spraying region 117a, and the chemical liquid or water is sprayed onto the required spraying region 117a through the fluid nozzle 60 (S4).

That is, the controller 120 drives the drive motor 78 of the moving body 72 to move the sprayer 9 to the spraying area 117a. At this time, the controller 120 is based on the current position of the moving body 72 is stopped and the position of the sensor 110 of the spraying area 117a, the moving body 72 is the spraying area of the drive motor 78 ( The driving time corresponding to the distance to travel to 117a may be determined, and the driving motor 78 may be driven during the determined driving time.

However, in this case, the temperature and humidity sensor 110 is separated from the moving path of the moving body 72 and the actual installation position of the temperature and humidity sensor 110 and the guide rail 75 of the guide portion 74. When the actual installation length is different from the design, the moving body 72 may not move correctly to the required spraying area 117a. Accordingly, in order to prevent such a problem, optionally, as shown in FIG. 3, the sensor unit 109 may detect the position of the movable body 72 so as to correspond to the respective regions 117, respectively. It may further include a plurality of position detection sensors 95 installed in the movement path, that is, the middle of the guide rail (74). The position sensor 95 may be an ultrasonic sensor, a photo sensor, or the like capable of detecting the movement of the object. At this time, the controller 120 receives the input signals input from the position of the moving object 72 sensed by the position detection sensors 95 installed corresponding to the required spraying area 117a, that is, the position detection sensors 95. On the basis of this, it can be determined whether the moving body 72 has reached the required spraying region 117a.

As such, when the moving body 72 reaches the spraying area 117a, the controller 120 operates the rotary motor 30 in FIG. 1 to direct the fluid nozzle 60 to the spraying area 117a. Next, depending on the size of the required spraying region 117a, that is, when the lift cylinder 12 in FIG. 1 is large, the height of the fluid nozzle 60 is increased, and at the same time, the blower fan 90 is driven at a high speed. The sprayed chemical is transported far forward, and if it is small, the lift cylinder 12 is contracted to reduce the height of the fluid nozzle 60, and at the same time, the blower fan 90 is rotated at a low speed to spray Transfer the chemical to the near front.

In addition, the controller 120 adjusts the rotational speed of the rotary motor 30 as shown in FIG. 3 so that the fluid nozzle 60 is disposed in the width direction (a) and the length direction (b) of the spraying area 117a. It is configured to be able to spray evenly the chemical liquid or water. That is, the regions 117 may have different widths and lengths due to their characteristics. Therefore, the controller 120 controls the rotation motor 30 so that the angular velocity of the fluid nozzle 60 is reduced in the longitudinal direction (b) portion of the spraying area 117a, and the width direction (a) of the facility (R). The part controls the rotary motor 30 so that the angular velocity of the fluid nozzle 60 is increased.

Thereafter, when the input signal input from the temperature and humidity sensor 110 of the required spraying region 117a reaches the reference value, the controller 120 stops spraying the chemical liquid or water by stopping the operation of the air compressor 70. .

This operation (S1-S4) is repeated whenever an area where the temperature and humidity value measured by the temperature and humidity sensor 110 is lower than the preset reference value occurs.

As a result, the control unit 100 of this configuration is configured to respond to the detection signal of the temperature and humidity of the respective areas 117 in the facility R input from the respective temperature and humidity detecting sensors 110. It is determined whether there is a need for spraying, and accordingly, the driving motor 78 of the movable body 72 is controlled to move the movable body 72 to the required spraying region 117a, and the spreader 9 is removed from the required spraying region 117a. The air compressor 70, the rotary motor 30, the lift cylinder 12, and the blowing fan 90 are controlled to control the amount of mist, mist direction, mist height and mist width of the chemical liquid in the spraying necessary region 117a. Adjust. Therefore, the controller 100 automatically adjusts the amount of mist, the direction of mist, the height of the mist, and the width of the mist for each region 117 to control crops in the facility R or to adjust the temperature in the facility R. Humidity can be controlled efficiently. In particular, when spraying water using the mobile spraying system 1 of the present invention, it is possible to ensure that the temperature and humidity of each of the regions 117 in the facility R can always be kept constant. In other words, the temperature and humidity in the plant (R) can be optimally adjusted for the crop to grow.

Meanwhile, in the present invention, the temperature and humidity detecting sensor 110 and / or the position detecting sensor 95 for detecting the temperature and humidity of each region 117 are configured as a wireless detecting sensor to conveniently position its position as necessary. It can be moved. In addition, in the present invention, the wireless receiver 130 is further provided to receive the output signal of the temperature and humidity sensor 110 and / or position sensor 95 output as a wireless signal. The radio receiver 130 inputs the output signals of the received temperature and humidity sensor 110 and / or the position sensor 95 to the controller 120. Of course, the temperature and humidity sensor 110 and the controller 120 may be directly connected by wire.
