Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a watering and spraying apparatus for a house, which is provided in a house to spray or spray water from above a cultivation bed or a ridge.

[0002]

2. Description of the Related Art In house cultivation, there is a method in which a nozzle is provided in a plumbing facility provided near a ceiling of a house to spray water on crops set in beds or ridges, or to spray chemicals or nutrient solutions. This method of watering or spraying is a method in which water, chemicals, nutrient solution, etc. stored in a tank are supplied to a watering pipe provided near the ceiling of the house with a power sprayer or the like, and nozzles are scattered throughout the length of the watering pipe. Watering or spraying. Although the arrangement of the nozzles is often referred to as a nozzle line, the nozzle line is linear, but there are various ways of providing the nozzle line. Most often, as shown in FIG.
A watering pipe 313 as a nozzle line is provided in the frontage direction X of the ceiling position of 00, and this nozzle line is connected to the depth direction Y.
It is a method of moving to.

As a specific example of the method, for example, a rail 320 in the depth direction is provided in the center of the width of the frontage of the ceiling, and a watering pipe 313 in the frontage direction is attached to a traveling arm 321 suspended from this rail. The water spray pipe 313 is provided with a power sprayer 3 from a tank 301 installed on the ground.
The water is supplied through a water supply hose 312 by a water supply 02 and is sprayed or sprayed from a nozzle 314 provided in a watering pipe 313. Since the traveling arm 321 can be moved in the depth direction by the driving device 322 provided at the end of the rail 320, it is possible to spray or spray water over the entire house by running while spraying water.

[0004] Such a water supply device is often used for watering water, while chemical spraying for control is often performed from a position close to a crop near the ground. However, depending on the situation, such a water supply device may be used for spraying chemicals and nutrient solution. The reason why the chemical spraying is performed from a position close to the crop near the ground is to uniformly spray the foliage on the front and back of the leaves. Therefore, when the medicine is sprayed from above the crop as in the above-described water supply device, foliar spraying is realized by spraying with mist-like water droplets. On the other hand, in the case of watering for the purpose of irrigation, relatively large water droplets are preferable. Like this
Since the required size of water droplets differs between water sprinkling and spraying of a chemical / nutrient solution, such a difference in water droplets cannot be obtained from the same nozzle. Therefore, it is often performed using different devices, tools, and the like.

[0005]

As described above, if the nozzle line is provided in the frontage direction of the house and is moved in the depth direction, the same amount of water can be uniformly sprayed on the entire house. However, when different crops are cultivated in one house, even if it is desired to separately spray an appropriate amount of water for each crop, there is a disadvantage that only uniform watering can be performed. In addition, water is evenly sprayed on the passages between the beds and between the ridges, and in this respect, useless water is used. Particularly, in a large-sized multi-story house, a large amount of water or the like is consumed for watering, and thus a large amount of water is wasted. In the case of spraying a medicine or a nutrient solution, this waste becomes even larger in terms of cost. Also, there are places in the house that are shaded by the structural materials and equipment on the roof, and such shades are usually due to the fact that houses are built in the north-south direction, and therefore crop lines such as beds are also in the north-south direction. Often, the bed is divided into good and bad sunshine. Therefore, even if the crops are the same, there are cases where it is desired to change the manner of watering, such as the amount of watering and the time interval for each bed, depending on the difference in sunlight.

Further, in the above-mentioned water supply equipment, water remains in a watering pipe after watering and a watering hose reaching the watering pipe, causing various problems. First, in summer, the residual water becomes hot water, and particularly in a watering pipe installed near the ceiling and exposed to direct sunlight, the residual water in the pipe becomes considerably high-temperature hot water. Therefore, the next time the water is sprayed, such hot water is sprayed, and there is a problem that the crop is damaged. In summer, in particular, the number of times of water spraying is large, so that the number of repetitions of thermal water spraying increases, which is a further problem. On the other hand, depending on the season, the unused period may be long, but in this case, the residual water will rot, and there is a disadvantage that the rotted residual liquid is sprayed at the next watering, or the nozzle is clogged with rot. Such troubles occur.

It is troublesome to use different watering and spraying methods depending on the type of water supply, as in the case of water from the ceiling and chemicals and nutrient solution from the ground. Separate water supply devices and tools are used for each. It is a burden to prepare. Therefore, the size of water droplets to be sprayed or sprayed is set to an intermediate size between that for large water spray and that for atomized medicine, and the watering device from the ceiling can be used for all of water, medicine, and nutrient solution. It is conceivable, but the water droplets and fog particles must be compromised. There is also a device in which a watering device is sprayed in the form of a mist, and the spraying of chemicals and nutrient solution on the foliage is mainly considered. However, spraying a drug or nutrient solution causes a problem that the drug remaining after use crystallizes and clogs the nozzle. Further, the residual liquid from the previous spraying or the like is mixed at the next watering, which causes inconveniences such as watering of water mixed with a chemical or spraying a chemical mixed with a nutrient solution. In the first place, it is not preferable to use a different spray (water and chemicals) in a state where the size of the sprayed water drops remains the same since the purpose of spraying is not sufficiently fulfilled. When the water is mist, the crop cannot be sufficiently watered. On the other hand, when the water droplets of the medicine are not large and mist, the medicine cannot reach every corner of the crop.
However, providing separate spraying equipment for water and chemicals is too burdensome.

In view of the above problems, an object of the present invention is to select a liquid to be sprayed or sprayed with a small facility, and to vary the amount of water sprayed for each bed, thereby saving water, chemicals and fertilizer. It is a watering and spraying device that does not take much time,
It is still another object of the present invention to provide a watering / spraying apparatus which can eliminate various problems caused by preventing residual liquid from remaining, and which can perform these operations by an easy operation.

[0009]

For the above purpose, the nozzle line of the watering spraying device is provided in parallel with the crop line, and this nozzle line can be moved in a substantially horizontal direction perpendicular to the crop line. Provided. Furthermore, the water supply to the nozzle and the water stop during the movement can be switched, and / or the movement speed can be adjusted during the movement. The term "nozzle line" refers to all nozzles in which a number of nozzles are arranged in a straight line or other fixed shape corresponding to a crop row such as a cultivation bed below, and can be integrally moved while maintaining this shape. A watering pipe is typically formed by arranging nozzles at intervals in a metal pipe, a PVC pipe, or the like. The “movement in a substantially horizontal direction” includes a slope-like movement along a gentle slope of a roof and a movement along a dome shape in the case of a dome-shaped roof. In short, anything that moves while crossing the bed at right angles with watering etc. may be used.

According to the above, since the nozzle line provided in parallel with the crop line can switch between water supply and water stop while moving in a substantially horizontal direction perpendicular to the crop line, water can be sprayed on the bed. Do. Watering can be stopped when passing through the passage between beds. In addition, since the moving speed can be adjusted, adjusting the moving speed on the bed will result in a small amount of water spraying at high speeds and a large amount of water spraying at low speeds. You can change the amount of watering. In addition, when moving along a passage where watering is not performed, the water can be passed at the maximum speed.

Further, the nozzle line is moved by a curtain opening / closing mechanism in the house. Therefore, a mechanism corresponding to the movement of the nozzle line defined above may be selected from various curtain opening / closing mechanisms in the house.
In general, most curtains set near the ceiling of a house are opened and closed by curtains in the frontage direction. For example, in the conventional sliding curtain, as shown in FIG. 4, one side in the depth direction of the curtain 324 is stopped by a curtain pipe 325 of a metal pipe having the same depth.
Some are opened and closed by reciprocating 5 in the frontage direction. The nozzle line can be moved by the curtain opening / closing mechanism by providing a nozzle directly on the curtain tube and also using the watering pipe.

Further, if the water supply is selectively performed from any one of the plurality of tanks, one device can be used for spraying water, medicine, nutrient solution, and the like. For example, the water inlet of the power sprayer is branched into a plurality of tanks via a switching valve, and water can be absorbed from a desired tank by operating the valve. It is not necessary to change the selection of the tank in the middle of watering, so it is sufficient to perform the preparation for starting the operation such as watering. However, the switching may be performed in the middle of watering if necessary.

Further, the water spraying apparatus of the present invention is provided so that the residual liquid remaining in the pipe after watering or spraying can be removed by suction. As a result, the residual water does not become hot water or rot, and alteration, crystallization, and the like of the drug and the like are suppressed.

As one of the means, the residual liquid is sucked by water absorption of the power atomizer. This is based on the assumption that a power sprayer is used for watering or spraying.
This will be described with reference to the drawings of the embodiment described later. The power sprayer generally has a water intake port for absorbing water from a tank via a water intake pipe, a water supply port for supplying water to a nozzle via a water supply pipe, and a spill port for discharging spillage. Further, the water supply pipe and the water suction pipe are connected by a communication pipe, so that the water absorption formed by the tank at the time of sprinkling is switched to the suction of the residual liquid from the communication pipe at the time of suction. At this time, the water supply from the water supply port is shut off, and the residual liquid sucked only from the spill port is discharged.
This allows the power sprayer to have two functions, such as water spraying and suction.

[0015] As another means, the residual liquid is sucked by water absorption of a pump. This is based on the assumption that a pump is used for watering or spraying, and suctions residual liquid by switching water absorption from a tank to water absorption from a water supply pipe.

If the washing water is introduced into the pipe after suction, the inside of the pipe after suction can be washed.
It is particularly effective after spraying a nutrient solution or the like. Since the washing water does not need to be at a high pressure like water supplied by a power atomizer, ordinary tap water may be used, and if it flows in and reaches the terminal nozzle, it may be sucked as described above.

When a power atomizer is used, the amount of surplus water can be adjusted. This makes it possible to adjust the water supply pressure at the time of watering or spraying, and if the water supply pressure changes, the size of the droplets of water droplets to be sprayed can be changed, so that when water is sprayed, large water droplets are formed, When spraying nutrient solution, it can be used properly so that it becomes fog. In addition, such adjustment of the residual water amount is performed in the same manner as the above-described tank switching.
What is necessary is just to perform preparations for the start of work such as watering, but if necessary, this may be switched during watering.

Further, such processing can be collectively and remotely processed by computer control of a programmable controller (hereinafter, PC) or the like. for that reason,
Input means for inputting initial information such as bed arrangement, a schedule such as time or number of times of watering or spraying, and instruction information including operation content and movement speed of water supply, and watering or watering based on the instruction information. A generating means for generating control information for spraying, a storage means for storing instruction information and control information, and a timer are included in the watering apparatus according to the present invention. In this way, the operation of watering or spraying is automatically performed by computer control while extracting necessary control information by a trigger by timer monitoring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a house watering and spraying apparatus according to the present invention will be described below with reference to the drawings. In this watering spraying apparatus, a curtain pipe of a sliding curtain provided near the ceiling of a house is also used as a watering pipe as a nozzle line.

First, the curtain opening / closing mechanism shown in FIG. 1 will be described prior to the water spraying apparatus. In the figure, the curtain is omitted, but when closed, it forms a ceiling and the house 200
It has a shape that covers the entire inside and upper part, and when the curtain is opened, it is brought closer to one of the walls in the depth direction. The curtain is opened and closed by stopping one side of the curtain in the depth direction with a metal pipe of the same depth and reciprocating in the direction of the frontage as a sprinkler pipe that also serves as a curtain pipe. It is to be done.
Also, two receiving wheels 201, 201 are provided at both ends of the frontage, and by rotating one receiving wheel 201 at a low speed, the endless wire 202 stretched here circulates in both forward and reverse directions. You can do it. Then, the sprinkler pipe 13 is attached to the wire 202 to open and close the curtain. The rotation speed of the receiving wheel 201 is adjustable, so that the moving speed of the sprinkling pipe 13 is adjusted. Actually, a large number of such wires 202 are provided at intervals of several meters in the depth direction, and the entire length of the water sprinkling pipe 13 is evenly moved. And keep the parallel relationship. Note that other mechanisms related to the curtain are not related to the present invention, and thus are omitted.

As shown in FIG.
Three tanks 1 and a power sprayer 2 for absorbing water therefrom;
The main configuration is a water supply hose 12 as a part of a water supply pipe 11 piped from a water supply port 10 of the power sprayer, and a watering pipe 13 connected to a distal end of the water supply hose 12.

The three tanks 1, 1, 1 include a water tank,
A tank for chemicals and a tank for nutrient solution are provided, and two systems are drawn out of a water absorption pipe 21 for absorbing water into the power sprayer 2 and a collection pipe 38 for returning spillage and the like. In addition, individual electromagnetic valves 22 and 32 are provided in these pipes, and the tanks 1, 1, and 1 can be selected at the time of water absorption and recovery.

The power sprayer 2 is connected to the water absorption pipe 21 from the tank 1.
, A water supply port 10 for supplying water from a water supply pipe 11 to a nozzle 14 of a watering pipe 13 through a water supply hose 12 as a part of the water supply pipe 11, and a water supply port 30 for discharging spillage water. And The water absorption pipe 21 is branched into three tanks 1, 1, 1, and can absorb water from a desired one tank 1 by operating the solenoid valve 22. The water supply pipe 11 and the water absorption pipe 21 are connected by a communication pipe 40, and a connection part with the water absorption pipe 21 is provided with a water absorption valve 23 of a three-way valve. The connection portion with the water supply pipe 11 is simply connected and has no bubbles. Instead, a shutoff valve 15 using an electromagnetic valve is provided between the connection portion and the water supply port 10. Both of these two connecting portions are provided close to the water inlet 20 and the water inlet 10. With the above piping system, the shutoff valve 15 is opened at the time of water supply, and the water intake valve 23 is switched to the tank side to disconnect the communication pipe 40 to supply water. When the residual liquid is sucked, the shutoff valve 15 is shut off, and the water absorption valve 23 is switched to the communication pipe 40 so that the residual liquid in the water supply pipe 11 (the pipe from the nozzle 14 to the end nozzle 14) is removed. It is sucked through the pipe 21 and the water inlet 20.

A spill pipe 31 is drawn out of the spill port 30, and a drain pipe 33 for draining washing water after washing is drawn ahead of the spill pipe 31.
Is provided via a three-way valve 34. Spill pipe 31
Is provided with a main valve 35 for adjusting the surplus water amount, which is set to a fixed surplus water amount. Further, a bypass 36 is provided for the main valve 35.
The bypass 36 is provided with a globe valve 37 capable of adjusting the amount of surplus water for determining the fineness of water droplets when watering. In other words, the amount of surplus water adjusted by the globe valve 37 is added to the fixed amount of surplus water at the main valve 35, and the degree of coarse and fine water drops or fog is determined. The spill pipe 31 is branched and connected to the collection pipe 38 of each tank at the end.

A hose from the water supply 50 is connected to the communication path 40, and the empty water supply hose 12 after suction is connected.
And water can flow into the sprinkling pipe 13.

The water supply hose 12 is long enough to withstand the extension caused by the opening and closing of the curtain, is crawls upward along the columns of the house 200, and is connected at the center of the length of the watering pipe 13.

The watering pipe 13 has a length corresponding to the depth of the house, for example, about 30 m. Here, downward nozzles 14 are provided over the entire length at intervals of about 1 m.

A PC (not shown) is used for controlling the computer. When the watering apparatus 100 is installed, the frontage length of the house 200, the width and number of the beds 210, the width of the passage, the tank 1
The suction time and the like calculated from the number of water supply hoses and the length of the water supply hose can be initially input from the touch panel.
Further, the selection of the tank 1 and the amount of water to be applied to which bed 210 and the like can be input from the touch panel as instruction information. The schedule is also input as the instruction information. After these inputs are temporarily stored in the storage device, the generating means generates control information using the instruction information, and the generated control information is also stored in the storage device. Thereafter, by starting the automatic operation, a timer built into the PC is monitored, and switching of various valves and start / stop of the power sprayer 2 are controlled by using a predetermined time or elapsed time as a trigger. Of course, it may be started manually. The computer control also has an opening / closing control function for only the curtain, which is performed separately from the watering work.

Next, a method of using the sprinkling apparatus of the present invention will be described. First, the above-described initial information is input when the watering / spraying apparatus 100 is installed. At this time, the instruction value of the watering amount and the moving speed value of the watering pipe 13 are matched, or the instruction value such as whether to spray water droplets or fog and the adjustment amount of the globe valve 27 are matched.

Next, at the time of each watering operation, a watering pattern required at that time is input as instruction information. As soon as the instruction information is input, it is processed by a computer to generate control information.

When the water spraying apparatus 100 is started, first, all the curtains are moved to the wall side, and a watering pipe 13 as a nozzle line is prepared at a watering start position. Next, the tank 1 is selected and the power sprayer 2 starts to operate, and desired watering is performed by supplying water according to the path A.

For example, a large amount of watering is instructed on the bed 210 located at a position where the sun is strong, and the watering pipe moves on the bed 210 at a low speed. Although the amount of water sprayed per minute is fixed, a large amount of water is sprayed on the bed 210 due to the low-speed movement. Bed 210 that requires a small amount of watering
At that time, move at high speed over it. Therefore, the bed 210
Watering can be performed according to the sunshine and crops. Further, when moving from the bed 210 to the adjacent bed 210, the water is stopped and the apparatus 100 is moved at the maximum speed. Therefore, there is no waste of water sprinkled in the passage, and the moving time of the passage is reduced, so that the working time is also reduced.

When spraying a medicine or a nutrient solution, the tank 1 is switched, and the adjustment of the amount of remaining water is changed, so that a mist spray suitable for foliar spraying is performed.

After the spraying is completed, the suction valve 23 is switched to the connecting pipe 40, and the shutoff valve 15 is shut off, whereby the suction by the route B is performed. The aspirated medicine is collected in the original tank 1, but since the medicine is collected from the water supply hose 12 and the watering pipe 13 of 30 m, the amount of collection is large. Next, the power sprayer 2 is stopped, the valve 51 of the water supply 50 is opened, and the fresh water as cleaning water flows into the water supply hose 12 and the water sprinkling pipe 13 through the path C.
The water reaches the end of the watering pipe 13 and the nozzle 14
After letting it flow in to the extent that it leaks a little, stop the water and again,
The suction is performed by the power sprayer 2. At this time, the three-way valve 34 for the drainage pipe 33 provided in the spill pipe 31 is switched to drain the cleaning water mixed with the chemicals and the like from the drainage pipe 33.

The present invention is not limited to the above embodiment. The connecting pipe may be connected to the water supply pipe via a three-way valve, and the shutoff valve may be omitted. The water supply valve may be omitted from the connection point between the connecting pipe and the water suction pipe, and an electromagnetic valve may be provided between the connection point and the water suction port. The inflow of washing water may be from a connecting pipe, a water supply pipe, or directly from a water supply hose.

[0036]

As described above, according to the first aspect of the present invention, since a desired amount of watering or spraying can be performed for each crop line, optimal watering or spraying can be performed for each bed. In addition, since water is stopped in the passage, there is no waste of water, chemicals, and fertilizer. In addition, since the passage can be moved at the maximum speed, the working time is short.

According to the second aspect of the present invention, since the movement of the nozzle line is performed by the curtain opening / closing mechanism in the house, the load on the equipment is reduced, and the existing equipment can be used.

According to the third aspect of the present invention, watering, chemical spraying, nutrient solution spraying, and the like can be performed by selecting from a plurality of tanks, so that watering or spraying suitable for crops can be performed.

According to the fourth aspect of the present invention, since the residual liquid is sucked, obstruction of water spraying or spraying such as decay or crystallization of the residual liquid can be removed, and water spraying or spraying water can be eliminated. Hydrothermal treatment of chemicals and chemicals can be prevented.

According to the fifth aspect of the present invention, since the power sprayer can perform the suction function, the increase in the function hardly increases the facility load.

According to the sixth aspect of the present invention, since the pump can perform the suction function, the increase in the function hardly increases the facility load.

According to the seventh aspect of the present invention, since the washing water flows into the pipe after the suction, the residual liquid such as the medicine is more sufficiently removed, which helps to prevent the pipe from being stained.

According to the eighth aspect of the present invention, since the amount of surplus water of the power sprayer can be adjusted, it is possible to select the fineness of water droplets or mist at the time of watering or spraying, and accordingly, it is possible to correspond to the type of watering or spraying liquid. it can.

According to the ninth aspect of the present invention, the above processing is automated, and particularly, the moving speed of the nozzle line and the adjustment of the residual water amount can be accurately and easily controlled.
