As shown in FIG. 1 and FIG. 2, the present invention relates to a watering method and a watering device for watering the crops so that the cultivated crops can stably grow with respect to the external environment. At the lower end of the vertical beams (3) consisting of two horizontal beams (2), a horizontal bar (11), which is a horizontal bar, was formed, and rails (4) were formed at both ends of the horizontal support (11). The rails 4, which are formed long before and after the ceiling of the greenhouse 1, are supported by a plurality of horizontal supports 4 extending from the plurality of horizontal beams 2, and the upper side of the rails 4 are open, so that the sprayers 5 A plurality of rollers 12 connected to each other are configured to move along upper rails 4 on both sides.

In addition, the transport frame 16 connecting the plurality of rollers 12 forms the basis of the conveying device Pa, and the lower side of the rail 4 is connected to both rollers 12, and also one side roller 12. A rectangular tubular rope frame 14 is formed on an upper side of the two shafts to support the front and rear sides of the greenhouse 1 so that the rope 13 interlocked with the driving motor M is provided on the inner side of the rope frame 14. It was configured to pass through. At this time, one side of the rope frame 14 to the rope fixing pin 15 to the rope 13 is fixed to the rope frame 14, the other rope frame 14 was configured to move the rope 13 smoothly.

As shown in FIGS. 4 and 5, pulleys are formed at the front and rear of the greenhouse, respectively, to be connected and driven by a rope 13, and at this time, one side of the pulley is configured to be driven by the driving motor (M). . And one side of the rope 13 configured in this way is supported and fixed to the rope frame 14 of the feeder (Pa) coupled to the sprayer, the other side of the rope 13 simply configured to pass through the rope frame (14). This causes the rope 13 to move as the driving motor M configured at one side is driven, and the rope 13 moves along the pulley configured at the front and rear of the greenhouse 1, thereby being fixedly coupled to one side of the rope 13. The conveying device Pa is configured to move with the rope 13.

And the upper and lower adjustment device (Pd) configured to extend down the feeder (Pa) is composed of legs extending to the outside formed on both sides of the transfer frame (16). That is, as shown in FIG. 6, the cylinder chamber 21, which is a cylindrical cylinder, is formed at the ends of the legs of the transfer frame 16 extending downward on both sides, and the cylinder chamber 21 is connected to each other to be flat. The flat upper and lower control frame 22 was formed, and the inner side of the cylindrical cylinder chamber 21 constituted a spherical support 31 having a circular rod shape. At this time, the sprinkling support 31 on both sides is formed vertically and the upper part is connected to each other in a horizontal configuration, and the lower side of the sprinkling support 31 is configured to extend the sprinkling tank 33 for spraying water. . And in the hole formed in the center of the flat upper and lower control frame 22, the shanghai pine screw 24 having a spiral formed on one side of the middle is cut off, the upper end forms irregularities, the upper horizontal connection portion of the watering support (31) The concave-convex portion of the up-and-down transfer screw 24 is configured to be rotatably inserted into the transfer screw bulb 25, which is a hole formed at the center of the bottom. And coupled to the shanghai pine screw 24 on one side of the upper and lower adjustment frame 22, the upper and lower adjustment motor 23 to the shanghai pine screw 24 to rotate.

Thus, as the up and down control motor 23 rotates, the shanghai pine screw 24 is rotated along the up and down control frame 22 to move up and down, thereby raising or lowering by the rotation of the shanghai pine screw 24, The feed screw rotary tool 25 coupled to the upper end of the shanghai pine screw 24 moves up and down together, thereby moving the spraying support 31 coupled with the spraying machine 5 up and down together. As a result, the sprinkler 5 is moved up and down, and the vertical movement of the sprinkler 5 changes the range of water to be sprinkled, that is, the size of the sprinkling water.

That is, as shown in FIG. 7, the water is overlapped with each other according to the height of the plurality of sprinkler (5), wherein the sprinkling is over-spreading section (c), which is over-sprayed excessively, and the normal spraying that does not overlap each other It is divided into sections (b), and sections (a) that are not sprayed at all by the spraying angle, and it is important to adjust the height so that the spraying water can be sprayed only by the normal spraying section (b). In other words, when the crop is young, the crop is grown to almost the same height as the ground, and when the height of the sprinkler 5 is increased, the overspreading section (c) and the normal sprinkling section (a) are overlapped. Crops are overgrown, and crops in the normal sprinkling section (b) grow slowly, resulting in uneven growth. Thus, when the crops are young, the watering height should be adjusted to be equal to the height of the normal watering section (b) dl which is halfway between the unspoiled section (a) and the overspreading section (c). As the crop grows gradually, the height of the watering machine (5) is raised to raise the position of the watering depth, so that the crops can be avoided in the normal watering area (b) while avoiding the section (a) and the excessive watering section (c) that cannot be sprayed without touching the crop. It can be sprayed so that it can achieve normal growth of crops.

And the crop detection device for detecting the planted portion of the crop is configured at both ends of the plurality of horizontal support (11) extending to the horizontal beam (2) of the greenhouse 1, as shown in Figure 8 to 10 Reflectors 17 are formed on the lower side of the circular rail-shaped both rails 4, and pairs are formed on the corresponding surfaces of the moving device Pa, which move the corresponding sensors 18 along the rails 4, respectively. It was. That is, as shown in FIG. 8, the rails 4 of the circular bar shape formed on the front and back of the greenhouse 1 above the plurality of horizontal supports 11 is made of metal, so that the reflecting plate 17 is lowered, After the adhesive portion 19, which is a permanent magnet, is directed upward, when the adhesive portion 19 is attached to the lower side of the rail 4 made of metal, the reflective plate 17 formed on the other side is directed downward. The reflective plate 17 attached to the rail 4 thus displays the planting position, which is a fixed position that is not moved because the rail 4 is fixed. Thus, whenever planting a crop, the adhesive part 19 composed of permanent magnets is formed. The peeled off and attached to the lower side of the rail (4) in accordance with the planting position of the planted again to mark the planting position.

And the sensor 18 corresponding to this is formed in pairs on both sides of one side of the moving device Pa by the roller 12 moving along the upper side of the rail 4, the sensor 18 and the reflecting plate thus configured (17) is configured to maintain a small narrow interval so as to correspond to each other to facilitate signal transmission. Thus, the sensor 18 is configured to transmit and receive a signal, and the corresponding reflecting plate 17 is configured to reflect the signal from the sensor 18, so that the sensor 18 at the planting position where the reflecting plate 17 is configured. When the moving device Pa is configured to pass, the signal from the sensor 18 is reflected by the reflector 17 and the sensor 18 detects again, and transmits the signal to the controller connected to the sensor.

The sensor used in the present invention is an ultrasonic proximity sensor, and the distance between the reflection plate (iron plate) and the sensor is within a certain distance, and the contact of the sensor is attached or dropped. In addition to the ultrasonic sensor, the proximity sensor may be a magnetic element line sensing Hall element sensor, a photocouple sensor by detecting the reflection of light.

The method of spraying only the planting position by the sensor 18 and the reflecting plate 17 configured as described above is, first, as shown in FIG. 9, when the feeder Pa configured with the sprayer 5 is advanced in the advancing direction. On the lower surface of one side rail A (4A), a reflecting plate a (17a) indicating a position where the crop is planted is attached, and the other rail B (4B) a reflecting plate b (17b) indicating a section where the crop is not planted. Attached. Therefore, in the greenhouse surface between the reflecting plate a 17a attached to the rail A 4A and the reflecting plate b 17b attached to the rail B 4B, the section A where crops are planted is shown. Therefore, when the feeder Pa moves forward, first, the one side sensor a 18a reacts with the reflecting plate a 17a to enter the planted section, and this signal is directly connected to the sensor a 18a. The watering machine 5 is watered by the controller. When the feeder Pa, which has been sprayed along the planting section A, reaches the reflecting plate b 17b configured in the section B where the crop is not planted, the sensor b 18b and the reflecting plate b 17b react with each other. This causes the sprayer 5 to stop spraying by the controller.

Then, when the feeder (Pa) reaches another section A where the crop is planted again after the section B where the crop is not planted, the sensor a 18a meets the other reflector a 17a and reacts with each other. When the water is sprayed on, and the crop reaches the section B where the crop is not planted, the watering is stopped by the sensor b 18b and another reflector b 17b. Thus, by installing a plurality of reflecting plate 17 indicating the planting position on the bottom surface of both rails (4) to detect the position where the crop is planted by a pair of reflecting plate ab (17ab) and sensor ab (18ab), respectively. Therefore, it is configured to spray only on the location where the crop is planted.

In addition, the present invention, as shown in FIG. 11, a plurality of water sprayers 5 are configured in the vertical plank-shaped stress bar 43 which is supported at both ends of the sprinkling rack 33 configured laterally of the greenhouse 1 ) By contacting with the cultivated crop 6 during forward and backward advancement of the feeder Pa, thereby stimulating the cultivated crop 6 so as to grow into a sturdy crop 6. That is, a stress bar traction table 41, which is a vertical bar, is configured on both sides so as to be able to swing at both ends of the spraying rack 33, which is composed of a cylindrical pipe so that water passes therethrough, and the lower side thereof, After each of the stress bar support 42 having a constant width long before and after the end is configured on each side, the board-shaped stress bar 43 having a vertically constant width so as to connect the stress bar support 42 on both sides of the stress bar support ( Three were constructed before and after 42). This causes the three stress bars 43 to move forward or backward, respectively, as the spraying table 33 is sprinkled, and to come into contact with the crops 6 in a wide width, thereby growing in the greenhouse 1. It gives the crop 6 a chance, thereby making the crop 6 grow stronger.

Looking at the watering method of the present watering device configured as described above, the watering device (Pc), and the driving motor of the spraying device (Pa), the upper and lower control device (Pd), the crop detection device (Pe), the stress device (Pd) is configured After the power is supplied to the controllers connected to (M) and the like, the height of the watering machine 5 is kept constant as an up and down control device so as to suit the height of a predetermined crop.

At this time, the driving method according to the present invention sprinkling apparatus is divided into a total sprinkling method and a partial sprinkling method, wherein the total sprinkling method is the start reflecting plate s (17s) and the end reflecting plate e (17e) respectively configured on the front and end surfaces of the rail 4; ) To start spraying from the start reflecting plate s (17s), finish the spraying at the position of the end reflecting plate e (17e), and then back up again and repeat the spraying. In addition, the partial spraying method is performed by a pair of reflecting plates ab (17ab) indicating the planting position of the crop (6) between the start reflecting plate s (17s) and the end reflecting plate e (17e) on the bottom of the rail (4). There is a way to spray only the planting section of (6).

First of all, the watering method by the whole watering method will be described in detail. According to the command of the controller, the conveying device Pa moves to the rear along the rail 4 in the first greenhouse 1, and is directly on the bottom of both rails 4. The sensors ab 18ab configured at one side of the feeder Pa are simultaneously positioned at the positions of the start reflecting plates s 17s configured at the same positions, respectively. At this time, since the pair of reflecting plates 17 reacts simultaneously with the two sensors ab 18ab to the first rail AB 4AB, unlike the reflecting plates a 17a or b 17b representing the planting position, respectively, separately reacting. Will react. The sensor ab 18ab reacted with the pair of start reflecting plates s 17s in this manner sends a response signal to the controller, thereby sending a signal to the sprinkler 5 of the sprinkler Pc connected to the controller. Water the crops. And the conveying device Pa is continuously advanced to the rear of the greenhouse 1 irrespective of the start reflecting plate s (17s), the sensor ab (18ab) and the watering device (Pc). Thus, when the transfer device is located at the pair of end reflecting plates e 17e formed at the rear of the greenhouse 1, the sensors ab 18ab of the transfer device Pa are positioned and react at the same time, and when this signal is sent to the controller, the controller At the same time again a stop signal to the feeder (Pa) and the watering device (Pc) to give a command to stop the watering. After that, the controller again issues a reverse command to the conveying apparatus Pa, which instructs the conveying apparatus Pa to go to the front of the greenhouse 1, and also, as the conveying apparatus Pa proceeds, the sprinkling apparatus Pc. In order to start spraying. Then, the backward conveying device Pa reaches the front surface of the greenhouse 1, and thus, the position of the pair of start reflecting plates s 17s is reached, so that the sensor ab 18ab contacts the start reflecting plates s 17s of the controller. When the response signal is sent, the controller issues the watering stop command to the watering device Pc again, and the stopper is sent to the transfer device Pa, thereby ending the cycle of watering. In this case, the reflector plate a17a and the reflector plate b17b indicating the planting position of the crops are the same at the same time because the position of the reflector plate which reacts with the sensor ab 18ab is set to be the same. Since it is not located at the position, it is set to react only when the positions of the reflecting plate 17 reacting with the sensor ab 18ab during the entire watering are the same, so that the reflecting plate a 17a and the reflecting plate b 17b indicating the planting position of the crops. ) Is not located at the same position at the same time, so it is set not to cause any reaction with the sensor ab (18ab) during the total watering. Therefore, the reaction device Pa having the sensor ab 18ab reacts while moving forward and backward of the greenhouse 1 only starts reflecting plates 17s and end reflecting plates positioned at the same position on the two rails AB 4AB. The reaction is performed only at the position where e (17e) is configured, which causes the whole watering to proceed.

Next, look at the partial spraying method, when the control unit of the main unit of the initial power input is given a forward command to the rear of the greenhouse to the feeder (Pa), the first pair of side by side reflectors (17s) do. However, unlike the total spray method, the controller receiving the signal by the start reflector s 17s does not send any control signal. And the feeder (Pa) continues to move forward, the sensor a (18a) is located at the position of the reflecting plate a (17a) of the bottom of one side of the rail A (4A) for the first time indicating the location where the crop is planted to signal Will be sent to the controller. At this time, no reflection plate 17 is located on the bottom of the opposite rail B 4B, so that the sensor b 18b does not send any signal to the controller, so that the controller only uses the sensor a 18a and the reflection plate a ( Only signal by 17a) is received. The controller receiving the signal recognizes the signal from the sensor a 18a as a sprinkling start command when the feeder Pa is advanced by the predetermined setting value, so that the controller starts sprinkling the sprinkler Pc. The sprinkler (5) will start the sprinkling by sending an order. Therefore, the watering device (Pc) is configured to start the watering only when the crop is planted section.

In this way, when the crops 6 are sprayed in the planted section, the main apparatus reaches the position of the reflecting plate b 17b formed on the bottom surface of the one side rail B 4B, the reflecting plate b 17b and the sensor b 18b. ) Reacts to each other and sends these reaction signals to the controller. At this time, no reflector a 17a is formed on the bottom of the opposite rail A 4A so that no signal is sent to the controller, whereby the controller recognizes that the crop 6 has come to the section B where it is not planted. As a result, the controller determines that the signals from the reflector b 18b and the sensor b 17b are the watering stop commands according to a predetermined value, thereby sending the watering stop command to the watering device Pc. However, since the reflecting plate 17 is not configured at the same position in front of both rails AB 4AB, no command is sent to the feeder Pa. And while moving without being sprayed in this way, the reflecting plate a 17a which shows another planting position is comprised in the bottom face of one side rail A 4A, and the sensor a 18a of the feeder Pa is located. When the sensor a 18a sends a watering signal to the controller, the controller sends a watering command to the watering device Pc, and again, the reflector b 17b and the sensor b 18b. If is placed in the same position again sends a stop command to the watering device (Pc). Finally, when the sensor ab 18ab reaches the rear of the greenhouse 1 at the same position of the bottom reflector e 17e at the same position on the bottom of both rails AB 4AB, the sensor ab 18ab ends. The signal with the reflector e 17e is sent to the controller at the same time, and according to the predetermined value, the controller interprets this signal as the backward signal after the stop of the transfer device Pa, and the signal is transferred to the transfer device Pa. This causes the transporter Pa to retreat to the front of the greenhouse 1.

After that, the sensor b 18b of the conveying device Pa and the reflecting plate b 17b formed on the bottom of one rail B 4B are located at the same position as the first advance and send a signal to the controller. Thus, the predetermined value, that is, the signal between the reflector b 17b and the sensor b 18b when interpreting the feeder Pa, is interpreted as the planting position of the crop 6, and recognized as a sprinkling start command, so that the controller recognizes this command. It is sent to the sprinkling device (Pc), thereby to start the sprinkling in the section where the crop (6) is planted. Subsequently, the conveying apparatus Pa is moved backward toward the front of the greenhouse 1 so that the reflecting plate a 17a and the sensor a 18a formed on the bottom surface of the other rail A 4A are in the same position. Sensor a 18a sends a signal to the controller. When the feeder Pa moves backward, the signal from the sensor a 18a recognizes that the crop 6 is not planted, so that the controller commands the watering device Pc to stop spraying. Will send

Then, as the back of the greenhouse 1 continues to the front again, the reflector b 17b and the sensor b 18b meet again to start watering by the controller, and also reflector a 17a and the sensor a 18a. Is located at the same position and sends a water stop command from the controller to the watering device (Pc). However, the signal controlling the feeder Pa is not sent from the controller to the feeder except for the signal from the end reflector e 17e after the first feeder Pa is operated. When the conveying device Pa is reached, the sensor ab 18ab is positioned at the position of the start reflecting plate s 17s formed at the same position as the bottom surface of both rails AB 4AB, thereby resulting in the backward movement of the conveying device Pa. As the simultaneous signal by the sensor ab 18ab is set to the value of the stop signal of the conveying device Pa, the controller stops the conveying device Pa by the signal received from the sensor ab 18ab at the same time. This ends one cycle of partial spraying.

And as shown above, the processing method for the values from the sensors ab (18ab) during the front and rear movement of the feeder (Pa) moved to the front and rear of the greenhouse (1) by the controller is predetermined Since it is controlled by the computer and the controller predetermined value to the true value, it can be sprayed according to the growth of the crop, and the stress bar configured under the watering machine (5) can cultivate more healthy and strong quality crops. Is configured to.

12 shows a circuit diagram of a controller of the present invention.

General matters of various safety devices are omitted and manual operation is also omitted. Each component is as follows.

MC2 is a magnetic contactor for power supply, PBS3 is a push-button switch for power off, PBS4 is a push-button switch for power supply, MC2-a is a positive logic contact point for MC2 contact, and MC3 is a motor forward rotation Supply magnetic contactor, MC4 is motor reverse rotation (Sprinkler reverse) Power supply magnetic contactor, S2 is automatic manual changeover switch, 17e-1 is the contact point (contact point) falls when 18c reflector and 17e sensor match in Fig. 9 , Contacts with contacts on the opposite side, 18C (ON) and negative logic contacts, TM is a timer that operates for 10 seconds when the MC2-a contacts are attached, MC3-a is the auxiliary contact between MC3 and positive logic contacts MC3, MC3 Is the electromagnetic coil to hold the MC3 contact point, PBS5 is the starter switch of the sprayer, 17S-1 is the negative logic contact of the 17S sensor of FIG. 9, that is, the contact point when it does not match the reflector 18C, and 17e-2 matches the reflector 18C. Contact point that is disconnected in case of inconsistent contact, MC4-a is MC4-a and MC4 The coarse contact point, MC3-b, represents MC3 and negative logic operation auxiliary contact point, and MC4 represents an electromagnetic coil for attaching the contact point.

The control method and operation of the present invention are as follows.

The control method is to turn on the controller and press the PBS5 button, the sprayer stops at the point where the 17S sensor and the reflector 18C shown in FIG. 9 coincide with each other. The controller configured the controller to automatically control to reverse and stop when reaching the 17S point. When the power switch PBS4 of the controller shown in FIG. 12 is pressed, the magnetic contactor MC2 contacts and supplies power, while simultaneously maintaining power to the electromagnetic coil MC2 by the auxiliary contact MC2-a. At this time, another MC2-a contact is attached and when start switch PBS5 is pressed at one end of MC2-1, the power is connected to the one-shot timer and the timer TM is turned on for about 10 seconds, so the power (current) is S2, 17e-1. , TM, MC4-b in turn to operate the electromagnetic coil MC3 and the MC3 magnetic contactor is in contact with the sprinkler driving motor is rotated forward to advance the sprinkler.

The MC3-a auxiliary contact is a self-holding contact that keeps the circuit power connected even when the timer TM is stopped. When the sprinkler continues to supply power, the reflector 18C of FIG. 9 reaches the 17e sensor point, and the 17e-1 negative logic contact is dropped, and the 17e-2 positive logic contact is attached, so that the forward circuit is interrupted and the power is connected to the reverse circuit.

That is, when 18C is out of 17S, the negative logic contact 17s-1 of the starting point sensor is attached, so if only 17e-2 contact is attached, current flows through the MC4 electronic coil, causing the magnetic contactor MC4 to come into contact with the sprinkler drive motor M. Rotates back the sprinkler.

The MC4-a auxiliary contact is a self-holding contact that keeps the circuit power connected even when the 17e-2 contact is off. In addition, MC4-b and MC3-b are interlock configurations that prevent simultaneous driving of the reverse circuit. Pressing the power OFF switch PBS3 during forward or reverse operation will cut off all power and move the sprayer forward. When the power is turned on again, the previous state will continue. If the sprinkler continues to reverse and the reflector 18C coincides with 17s, the 17s-1 contact drops and the sprinkler stops. COM contact is a contact that can give an operation signal by an external controller (computer).
