Next, how to use the sprinkler system of the present invention when activated will be explained.

After inserting and coupling the water pipe of the reel device illustrated in FIG. 13 to the joint JT shown in FIG. Move to the other end of the field while pulling it out. After that, water is pumped up from a reservoir or groundwater etc. by a water pump and sent under pressure to a reel device, and further sent to a water sprinkler device via a reel section, where water is sprinkled in the form of fine droplets from water nozzles P321, P321,... . There are two types of driving force for the reel device that pulls in the watering device of the present invention: a turbine-driven type that uses the momentum of inflow water, and an engine-driven type that uses a small engine. It is preferable to use an engine-driven type, which allows easy setting of a wide range of speeds.

Hereinafter, the case where the watering device of the present invention is used for watering, pest control, and liquid fertilizer application will be described.

[When used as a water sprinkler] Water sent from the reel device with a water supply pressure of usually 4 to 5 kg/cm ² passes through the joint JT, the water supply pipe P1 and the main pipe P2, and reaches the rear of the machine, where it is connected to the T-shaped Enter the dispersion branch pipe P3 installed on the left and right sides of the socket PC,
sent towards the end of the tube. In this example, a reducing T-shaped socket PC, PC,
..., and one end of a flexible pressure-resistant hose P31 is attached to the small-diameter female thread on the side, and the other end is a nozzle mounting body with a shutoff valve P322, and the tip has a hole diameter A water nozzle P321 that sprays in a fan shape of 3.5 to 5 mm is screwed. The spray width of the water spray nozzle P321 is 4 to 5 m in the above water pressure range, but in order to achieve uniform water spraying, it is preferable to make the installation interval slightly smaller than in the embodiment. The water spraying direction of the water spray nozzle P321 can be set to the horizontal direction, and it can be positioned near the ground surface.

In the case of water sprinkling, the water supply to the bypass pipe P4 of the water pipe system P shown in Fig. 4 is completely shut off by closing the control valve SV3 and the three-way valve SV4, and the control water valves SV1 and SV2 are fully opened. Do it.
The amount of water sprayed from each nozzle changes depending on the water pressure applied to each part of the water sprinkling branch pipe, so by investigating the relationship between the water supply pressure and the amount of water sprayed experimentally in advance, the pressure shown on the pressure gauge PRS3 can be adjusted to the water control valve SV2. You can adjust the amount of water to predict the desired watering amount.

When the inclination of the watering device to the left and right increases due to irregularities in the field, the difference in spraying position at both ends of the watering branch pipe increases, and the uneven distribution of sprayed water due to crosswinds increases.
Therefore, an automatic parallelism maintaining circuit is installed so that the relative position of the water spray nozzle P321 with respect to the ground surface can always be maintained within a predetermined height range. Note that the automatic parallelism maintaining circuit will be described later.

[When used as a pest control machine] In the water supply system when used as a water sprinkler, close the water control valve SV1 of the main pipe P2 and close the water control valve SV1 of the bypass pipe P2.
By connecting the three-way water pipe SV4 to the short-circuit pipe P4S side through the water pipe P4, water flows from the water pipe P1 to the spray water branch pipe P3 via the bench lily pipe M1, the short-circuit pipe P4S, and the water control valve SV2. Water pressure from 5 to
Increasing the weight to around 6Kg/cm ² and increasing the nozzle diameter to 2~
When narrowed to 3 mm, a spray state with small mist droplets can be obtained.

When water flows through the bench lily pipe M1, a pressure difference is generated between the flow passage constriction part in the pipe and the ordinary part in front of it. Since the normal diameter part has high pressure and the throttle part has low pressure,
A part of the water passes through the liquid fertilizer extrusion pipe M21, pushes up the inflow water identification buoy M22, enters the chemical liquid fertilizer tank M3, and pressurizes the inside. The pesticide solution in the chemical fertilizer inner bag M3I of the chemical fertilizer tank M3 is squeezed out and transferred to the pipe M2.
3, it is mixed with water from the Kotoku M231 at the constriction part of the bench lily pipe M1, which is a low pressure part, and becomes a diluted liquid with an almost constant concentration, which is sent to the nozzles P321, P321,
...is sprayed towards the crops. Liquid fertilizer delivery pipe M
23, the rotor M2311 has conduction holes with different diameters opened in the cross direction as shown in Fig. 9, and in the case of pest control, it is oriented so that the chemical solution mixes through the 2 to 3 mm pores. Set.

In addition, the amount of chemical solution used is much smaller than the amount of liquid fertilizer used, and it is not possible to control pests using normal large-scale spraying methods.
1000-1500 times diluted drug per hectare
Because you only need to spray about 500 to 1000 liters,
One time of spraying requires only 10 to 20 liters. Therefore, since only a small-capacity chemical tank is required, the aircraft can be made lightweight and compact.

[When used as a liquid fertilizer spreader] Most of the water sent from the water supply pipe P1 flows to the main pipe 2, and part of it passes through the bypass pipe P4 and is distributed to the left and right porous holes at the rear of the machine by switching the three-way Kotoku SV4. Sent to pipe PM1. Since the short-circuit pipe P4S is closed at the three-way joint, the water in the main pipe passes through the spray water branch pipe P3 and is sprayed over the entire width from the water nozzles P321, P321, ... hanging down immediately after the porous pipe PM1. .

In the bypass pipe P4, the liquid fertilizer in the chemical fertilizer inner bag M31 is delivered and mixed with water in the bench lily pipe M1, but in order to increase the amount of mixed fertilizer, the fertilizer delivery pipe M2
It is necessary to reduce the conduit resistance of No. 3, and as shown in FIG. 9, the conduction hole of the rotor M2311 in the constriction part is set to be a thick hole with a diameter of 5 to 6 m. If the pipe diameter, length, opening of the pothole, etc. of the mixing system are constant, the mixing rate of liquid fertilizer will be almost constant. In the example, if the water pressure applied to the main pipe is 4 to 5 Kg/cm ² , the water pressure applied to the bypass pipe P4 is 0.1 Kg/cm ²
to 0.075Kg/ ^cm2 . In Fig. 4, while looking at the liquid column meter MM, which is located between the three-way tank SV4 and the porous pipe PM1, and which is not shown in detail, open and close the water control valve SV3 of the bypass pipe P4, and open and close the water control valve SV3 of the bypass pipe P4.
change the pressure applied to the

The porous pipe PM1 is provided with liquid fertilizer delivery holes at regular intervals, and the liquid fertilizer flows down from each hole over the entire width of the porous pipe PM1. Even if the liquid fertilizer adheres to the crop, it is cleaned with sprayed fresh water from the spray nozzle P321 located immediately after it. The capacity of the inner bag M31 of the chemical fertilizer is 75 liters in the example.

[In the case of a spray pipe inclination adjustment device] In the case of the automatic leveling function, when the perforated pipe PM1 is tilted during liquid fertilizer distribution, a head difference is created at both ends of the perforated pipe PM1, causing uneven fertilization. Therefore, while it is necessary to keep it horizontal at all times, in watering and pest control, the distance between the ground and the crop must always be constant in order to maintain uniform watering and the adhesion rate of the chemical solution to the crop. It is necessary to run parallel to the ground surface at all times. The operation of the embodiment shown in FIGS. 11 and 12 is as follows.

In FIG. 7, first, the case of an automatic leveling device will be explained.

If one of the support wheels sinks due to unevenness in the field,
The weight B52 on the spray tube support device touches the micro switch E8 on the inclined side and the delay timer E5 is activated.
1, energize E52. Day delay timer E51,
For E52, if the left and right microswitches E8 and E8 are repeatedly connected in a short period of time due to the vibration of the weight B52, an excessive load will be applied to the motor E7 and the relay and safety device will burn out. , in order to prevent this, in the example 0 to 20
We are using a device that allows the input delay time to be set within a range of seconds.

On the other hand, the driving power is 24 volts DC, and the battery E1
1, supplied from E12. A two-pole, double-throw automatic/manual changeover switch E41 via the main switch E2 with a safety device can switch between automatic operation and manual operation in which the electric motor is rotated forward or reverse as appropriate. If manual, use left/right tilt setting switch E42
By turning the switch to the right or left, the DC motor E7 rotates forward or reverse, transmitting this rotational force to the reduction gear E6, and then transmitting it to both sides of the main support pipe via the chain transmission. By rotating the attached threaded chain wheels E62, E62 and raising and lowering the support pipe screw shafts E64, E64 that engage with these, the spray pipe support device and the spray water branch pipe P3, which is attached thereto, can be removed. P3 and the perforated pipe PM1 can be tilted together.

When the automatic/manual changeover switch E42 is turned to the automatic side, electricity reaches the input sides of the forward and reverse relays E31 and E32 connected to the normally closed side, and is sent to the timers E51 and E52 with input delay devices.
The automatic parallelism maintaining circuit becomes ready for operation together with the circuit from the microswitches E82 and E82 mentioned above. The output side of the relay is connected to the motor by crossing the conductors from both relays E31 and E31 to change the polarity. Therefore, micro switches E8, E8
When actuated, electricity flows to the operating coil of the right or left relay, causing the motor to rotate forward or reverse.

FIG. 11 shows an example of wiring related to an automatic/manual changeover switch E41, a manual left/right tilt adjustment switch E42, a timer for an automatic leveling device, and a microswitch. Routes A, B, and C are
Dual-purpose relays E31 and E32 shown in Fig. 12,
It is connected to a DC motor E7 and a selection switch E43 for switching the slope detection current of the relay operating coil.

Further, in the case of an automatic parallelism maintaining circuit, an example of the wiring relationship of each device is as shown in FIG.

When the automatic/manual changeover switch E41 is turned to the automatic side and the selection switch E43 is switched, the connection of the operation coils of the relays E31 and E32 for forward and reverse rotation of the DC motor from the leveling device is set to automatic parallelism maintenance. Connected to the electrical system side. Considering the fact that it is used in a high-humidity environment with sprayed water and pesticidal chemicals, the embodiment uses a sealed capacitance gas contact switch E as shown in Fig. 10.
92, E92 was used for the distance detection section. In addition, in the embodiment, the extension branch pipes B21 and B21 of the dispersion pipe support device are
Detecting parts E9, E9 were suspended from the lower part of the ring by chains of variable length near the ground surface between the crop cultivation rows at approximately the center of the field. The detection distance is 20-25mm. When one of the proximity switches E9 is activated, the relay E451 becomes energized, and then the current passes through the normally closed relay E44 and the changeover switch E43, and closes the DC motor E7 and the forward or reverse rotation relays E31 and E32 to a predetermined value. Rotate in the direction of If the field is curved and concave, turn the proximity switch E9 on the left and right sides of the watering system.
2, E92 may both operate. In that case, since there is no need to tilt the spray water branch pipe P3, etc., the normally closed relay E44 is opened to cut off the current to the relay operating coil for the motor. That is, as long as either the left or right proximity switch is activated, a current for forward or reverse rotation is sent to the electric motor, and the distance of the spraying device to the field is adjusted to be the same on both sides.

〔Effect of the invention〕

As described above, since the wide spreading pipe support device of the present invention has water nozzles and liquid fertilizer spreading pipes arranged at predetermined intervals, it is compared to the conventional intermittent swing sprinkler system with a single nozzle. This results in extremely uniform dispersion.

When watering, use a nozzle with a large diameter,
In addition, when water is sprinkled horizontally near the ground surface, there is less disturbance (drift) caused by wind, and the water droplets hit the soil on the ground surface strongly, breaking down the aggregate structure.
When the soil dries out, there is very little risk of forming a crust that inhibits seed germination.

When used for pest control, it is necessary to replace the nozzle with a slightly smaller diameter, but no tools are required for replacement, and the number of nozzles is half to one-third that of watering. All you have to do is twist the stopper to shut off the spray.

Since the relative height of the nozzle to the crop is maintained based on the ground surface by the automatic leveling function, uneven spraying due to topography and uneven adhesion of the chemical solution to the crop body are eliminated.

The biggest problems when applying liquid fertilizer are uneven growth of crops due to uneven spraying, and fertilizer burn due to electrolyte fertilizer adhering to crops. The above-mentioned problem does not occur at all because the liquid fertilizer is maintained at a constant temperature to suppress the occurrence of uneven spraying, and fresh water is sprayed and washed immediately after spraying the liquid fertilizer.

As described above, since the present invention has a structure that can be used for multiple purposes, the annual usage time can be extended, and the water sprinkling and water supply facilities can be used effectively, so it is economical. Furthermore, since it enables detailed watering and fertilization management, it greatly contributes to the production of high-quality, uniform agricultural products.
