 Background art

 Recent field irrigation generally uses a pipeline system in which water is supplied by a pump or the like and sprayed from sprinklers, perforated pipes, nozzles, etc. (hereinafter collectively referred to as “discharge ports”). From the standpoint of labor-saving and multi-purpose! 5, not only water is sprinkled, but also pesticides, liquid fertilizers, etc. (hereinafter collectively referred to as "chemicals") are mixed by mixing equipment. However, the method of spraying from 放出 to the same release is widespread.

 Ideally, when this chemical is applied, it is ideal to apply it evenly on the surface of the target object, for example, the leaves of the crop. For this reason, the position of the release \ :. Conventionally, it has been common practice to change the sprinkler width. The river has been.

However, in these Γ4 sprinklers, there is a problem that since the position of emission I is fixed, death q, which cannot be spread evenly, is 4 times. As a solution, fern 1 1 place i itself! It has been thought that each proposal has been made, but it has not solved one of the fundamental solutions. For example, as an example of the prior art, there is a method in which a sprinkler is moved and spread while being able to move to Ht. '-| Not far from mobilization.

 As another example of the prior art, there is a method of providing an electric or hydraulic automatic moving device for dynamically moving the position of the discharge U, but a driving power source is required in the case of the electric type. Is a big problem. Also, in the case of the hydraulic type, there is a problem that a separate supply pipe ffl water supply pipe is required in addition to the supply pipe of the spray liquid, and the drive work is completed especially when spraying the chemical liquid. In addition, there was a problem that the driving water had to be discarded in another place in order to avoid mixing with the chemical, which wasted. For the above reasons, it was considered that it was not easy to automate the movement of the position of the discharge port such as a sprinkler.

Therefore, the present invention drastically solves the problems of the prior art, and the design 'manufacturing-maintenance ¹⁵ ' is easy and compact, the cost is low, and the operation is automatically performed by reliable and stable operation. The discharge channel 1 of the discharge fluid is moved to make uniform distribution of the fluid a useful function, and the discharge fluid itself is used as a drive fluid for moving the discharge port.This simplifies the fluid supply piping and wastes the drive fluid. It is an object of the present invention to obtain a fluid discharge device that can completely ill operate over the entire operation process. It is another object of the present invention to obtain a pipeline system which can easily and economically perform one-motion control using the fluid discharge device. ^^

 In the wood invention, at line ii j of Γ, Γ Biston, one of the cylinders is blocked by the inlet flow path, and one cylinder on the opposite side of Biston is described to the discharge 1J. It may be configured to be passed through.

 Further, in the return stroke of the piston, a cylinder chamber communicated with the inlet flow path during the forward stroke is communicated with the discharge port, and a cylinder chamber on the opposite side with respect to biston is connected to the inlet flow passage. It may be configured to be blocked by a road.

In the return stroke of the piston, both of the cylinder chambers are blocked by the pre-filled flow path and the discharge port, and the piston force is returned by a separately provided urging means ^. It may be configured to move.

 Further, a flow rate adjusting means may be provided at at least one position in the communicating flow path.

 Hereinafter, the present invention will be described in more detail based on the example shown in FIG. Note that common parts in the respective drawings are marked with a common drawing symbol ^.

 FIG. 1 shows a first embodiment of the fluid discharge device A. of the present invention. The inlet channel a of the present apparatus is connected to a fluid supply source via a pipeline, and the outlet channel b is connected to a discharge port E such as a sprinkler.

A cylinder 1 force ^{f is} formed inside the drive device B, and a piston 2 is slidably accommodated in the cylinder 1 via a seal portion 2 s. To the piston 2 reciprocating in the cylinder 1 is fixed a port 3 which penetrates the lid of the cylinder 1 in a sealed manner, and the extended end of the rod 3 serves as a driving force transmission mechanism D. Through the outlet E, and drives the outlet E back and forth. The cylinder chambers e 1 and e 2 formed with the piston 2 interposed therebetween are connected to the pie mouth device iiC via respective communication passages.

The pilot device C is operated in cooperation with the reciprocating motion of the piston 2 to selectively switch each cylinder chamber e 1; e 2 to at least one of the inlet flow path a and the discharge port E so as to pass through. It has become. In this embodiment, the pilot unit ftC is a rod that hermetically passes through the container 11 having the chambers f1, f2, f3, f4, f5, f6, f7, and f8. 1 6, 17 Valve installed in 2, 1 3,. 14, 1 5 force Corresponding valve; 1! The rod: I 6; 17 engages with the reciprocating excitation of the piston 2 via the fast-moving engagement part 31. First, at hJ / Inj) during the operation of Viston 2, cylinder 1 ': f; ie 1 is a person! I Passed through channel a, and cylinder 1e 2 is released to ii W 1 E, and in piston 2 ¾i¾ 行行 ¾ (down force in 1), the human channel a during the forward movement .; § ^• the cylinder one ¾E 1 forces now which has been communicated to the release I 1E, shea Linda the j乂纣- side - e 2 is adapted to turn is to the human [I碰a. Note that \ \ In the example shown, the pilot C is divided into the lower two parts JL1; 11. It goes without saying that this may be a short break.

 The urging force stage 32 provided in the fast-moving engagement portion 31 is for ensuring the linking operation by providing elasticity when the pre-moving engagement portion 31 is brought into contact. That is, the valve bodies 12, 13, 14, and 15 of the pilot device C, once closed, will stick to the core valve seat due to the pressure difference between before and after the valve bodies. When the ffl force from the biasing means 32 and the piston 2 accumulates the ffl force and exceeds a predetermined limit, the pipe mouth device C is deflected for the first time. It plays the role of a kind of toggle switch. However, even if there is no urging force, the pilot operation is performed for a while, so that the urging force means 32 can be omitted.

 The driving force transmission mechanism D from the driving device B to the discharge port E includes a motion widening mechanism, a booster mechanism, a speed change mechanism, a speed adjustment mechanism, a reverse rotation mechanism, a turning mechanism, an intermittent motion mechanism, a rapid return mechanism, and a slow motion mechanism. By appropriately interposing a mouthpiece mechanism, a braking mechanism, etc., the movement form of the discharge port E can be variously changed. In the present embodiment, as an example, the movement of the piston 2 by the pantograph-type widening mechanism is described. An example is shown in which the width is transmitted to the discharge port E by expanding it, and the discharge port E is largely moved.

 A sprinkler, a perforated pipe, and a nozzle may be attached to the tip of the discharge port E in accordance with the form of discharge.This example: In the present embodiment, a sprinkler is attached as an example. I have.

 The operation of the present invention will be described with reference to FIG.

When the valve rests of Biston 2 and pie mouth device C are at the beginning of Les 1 (the state where the I-sub has been fully lowered), '' ^{: When} fluid supply is started from the road, Since 2 is equal to i, a person Γ 1 flow path a-'Ά i 1-→ f 2-力 force flowing to cylinder 1 ^ e 1 through the path of path p 1 \ The fluid is valve closed 1 3 Because the chain is tied, ': f 3 is not possible to go out. The _ mosquito in the cylinder] is,'-then biston 2 7H j-: j Start i (the figure width ^) l ^. On the other hand, the fluid of the cylinder ': e 2 I person j is pushed by the biston 2, but since the fluid has a valve body of 15 m, it can not exit' Valve rest 1 of 4 | passed by valve "efficient f 5—chamber f 6—exit 1.:1 through channel b, ejected toward □ E. During this process, ejection 1 :: 1 E Releases the runaway while rising by piston 2 and the driving force transmission mechanism D.

When the rod de 3 force with the forward stroke of the piston ^2? Rises, the biasing force means 3 2 force? Accumulates acting force from the piston 2, interlocking engagement part 3 and eventually exceeds a predetermined limit 1 power ^s Paiguchi' winding device rod head 1 6 C; 1 7 press upward in the drawing is inverted.

Then, the supply fluid from the pipe flows into the cylinder chamber e 2 through the path of the inlet passage a—chamber f 8—chamber f 7 → communication passage p 2 because the valve body 15 is open. ^?, its fluid can not leak out of order chamber I 6 of the valve body 1 4 is closed Te end, the pressure in the shea cylinder room e 2 rises Bisuton 2 force复帰movement stroke ( (Downward direction in the figure). On the other hand, the fluid in the cylinder chamber e 1 is pushed by the piston 2, and the fluid cannot leak out through the chamber f 1 because the valve body 12 is closed, and is opened by opening the valve body 13. Chamber that can pass through ί 4—chamber f 3-”is pushed out to outlet E through mouth channel b. During this process, the discharge □ E releases the fluid from the force that does not fall F by the piston 2 and the driving force transmission mechanism D.

When this opening with the return motion stroke of the piston 2 head 3 ^force? Descends, the biasing force means 3, and蓄稅the work mosquitoes from the piston 2, Jutsudogakari engaging portion 3 and eventually more than Tokoro limit Push the rod 1 6; 1 7 of the 1-pilot device ^ C toward the | Then, the movement of W-Biston's Biston 2 was started, and these royalties were repeated thereafter.

In addition, the flow control means 41 and 42 provided in the communication passage pi; p 2 subbed can control the speed of the piston 2 in the direction of flow. If it is crested, the piston line of Piston 2 will become 、, and the flow control stage 4 It becomes difficult.

 From now on, the operation of 迚 will be encouraged て.

^ '' n ^ 9 Since each release, 1E for each release ι: Neither contact operation nor remote operation is required, complete operation of the entire operation! II Can be fully automated It is convenient. In addition, the supply fluid reciprocates the piston 2 in the cylinder, and the fluid that has passed through the cylinder 11 is discharged from the discharge port.Therefore, the fluid supply pipe to this device should be discharged. Only one fluid pipe is required, and there is no need to separately supply working fluid for driving the discharge port and then separate disposal, and of course, no power supply is required, and it is easy to standardize and manufactured at low cost. Has the special advantage of being able to

 FIG. 2 shows a second embodiment of the present invention. In the first embodiment, the communication passage from the chamber ΐ3; f6 of the pilot device C to the discharge port in the first embodiment is integrated. Instead, they communicate with the outlets E 1 and E 2 via outlet channels b 1 and b 2, respectively. In this case, for example, by providing sprinklers having different discharge angles at the discharge ports E 1 and E 2, the fluid discharge mode can be further diversified.

Other configurations and operation modes are the same as those of the first embodiment, and thus detailed description is omitted. FIG. 3 shows a third embodiment of the present invention. In the one embodiment, the arrangement of each chamber and each valve body in the pilot unit C is changed to form an integrated container 1. It was stored in 丄. Along with this change, the pre-engagement engagement 31 of the piston 2 and the pilot is also changed to a type in which the piston 2 is made in the opposite direction to that of the first embodiment via the reversing lever. I have. In the third example, 2. In the example and 施, instead of combining the path from pilot device i C to ': if 3; It is possible to go around each of the HUs at time _t .

In this case, a bypass path D 3 is connected to the liSJ of the flow path a and the output flow path b, and the flow path step 43 is adjusted in the flow path ρ 3. Also by In this example, the speed of piston 2 can be reduced. This flow adjustment stage

If you add 4 3 to Biston 2 (vr.

 Other configurations and operation modes are the same as those of the first embodiment and the second embodiment, and thus the description is omitted.

FIG. 4 shows a fourth embodiment of the present invention, and realizes the reciprocation of the piston 2 while simplifying the configuration of the pilot device C in the third embodiment. In the forward stroke of the piston 2, the cylinder chamber e1 is communicated with the inlet passage a, and the cylinder chamber e2 on the opposite side is communicated with the outlet E, similarly to the third embodiment. However, in the return stroke of the piston 2, the cylinder chamber e1 and e2 are both entered into the! Threaded, it has a mechanism for the piston 2 ^force? Return movement by the force means 4 provided separately.

 In the present embodiment, the pie mouth device is £. Is configured such that one valve element 21 mounted on a mouth 16 sealingly penetrating a container 11 having a chamber g 1; g 2 opens and closes a pair of core valve seat openings. The rod 16 is interlocked with the reciprocating movement of the screw 2 via the interlocking engaging portion 31. First, in the forward stroke of biston 2 (upward in the figure), the cylinder chamber e1 is communicated with the inlet channel a, and the cylinder chamber e2 is discharged quickly to the discharge port E. In the return movement stroke of the piston 2 (downward in the middle), the cylinder chambers e 1; e and ¾g 1; g 2 are all substantially the same by opening the valve body 21. j The king power, the pressure around the piston 2 rises, and the piston 2 recites by the force of the biasing means 4 (spring in the figure). E2 is to be passed on to IE for release.

 The mode of work is explained based on No. 4.

Piston 2 and the pie hole Tsu door ¾ ^ 〇 of the valve body 2 1 ^-?, ^ Hatsukurai i have completely drop-off piston 2 force de in the state屮which is in it as the Na f- holiday 2 1 force Mochihige When the fluid supply is started from the channel in the closed state), the fluid will flow to the I channel a— 1— The force flowing to the cylinder e1 after the end of the passage p6, the fluid cannot flow out through the g2 because the body 21 is mi, and the cylinder 1? ii) The force in e 1 starts and the piston 2 force starts the UJ process (the direction of force in the figure). On the other hand, the fluid in the cylinder ¾ _e 2 can be passed by the force pushed by the piston 2, and the flow cannot flow out of the chamber g 1 because the valve element 2 1 is closed. It is extruded through outlet channel b toward discharge I-co E. During this process, the discharge port E discharges the fluid while ascending by the piston 2 and the driving force transmission mechanism D. In addition, the valve element 21 of the pilot device C sucks on the valve seat due to the pressure difference between the chamber gl and g2 and maintains the closed state.

When this opening with the forward stroke of the piston 2 head 3 force ^s rises, the biasing force means 3 2 ^force? Accumulates the action force from the piston 2, the interlocking engagement portion and eventually exceeds a predetermined limit 3 1 is the pie mouth device. The Si C mouth 16 is pushed downward in the figure to reverse it, and the suction of the valve body 21 to the valve seat is released. The valve is opened by the force of the biasing means 18 (weight in the figure).

 Then, since the valve body 21 is open, the fluid supplied from the pipe passes not only through the cylinder e 1 but also through the g path of the chamber g 1-the chamber g 2-the communication path p 5, and the one cylinder of the cylinder It also flows into e 2, and the cylinder chamber e 1; e 2 and the chambers g 1; g 2 all have substantially the same internal EE force. Therefore, the pressure after the piston 2 disappears, so that the piston 2 does not rely on the front and rear pressures, but rather does not bias. Start ¾ (d direction in 1). The fluid in the cylinder ¾ e 1 passes through the chamber g 1 — ¾ g 2 — blocking passage p 5 through the valve body 2 1 Ι】 and merges with the fluid in the cylinder ¾ e 2 Then, both of them flow out of \ 1 flow path b and flow out toward IIE. The submerged bleeding EE releases the fluid while descending by the piston 2 and the driving force transmission mechanism D; 1;

If the head 3 descends on the ^ 'of the piston 2, the 忖 / Τ · stage 3 2 will generate the power of the piston from the piston 2 and eventually exceed the expected point. M Intermediate part 3 1 pushes the mouth of the pie mouth ii¾ C, the mouth of the C 16, against the force of the 反 転 屮 さ せ る そ し て そ し て そ し て そ し て そ し て. Thereafter, these works j are repeated.

 The speed of the reciprocating movement of the piston 2 can be adjusted by the flow rate adjusting steps 44 and 45 provided in the speed passages p 4 and p 5. The forward stroke of piston 2 becomes slow, and if the flow control means 45 is squeezed, the return stroke of biston 2 becomes stronger.

 As for the urging means 4 of the piston 2, there is a method of holding a predetermined self instead of attaching a spring, or attaching a weight to the valve. As for the power means 18, there is a method in which a predetermined weight is maintained instead of mounting a weight, or a spring is mounted.

 As described above, in the case of the present embodiment, as in the case of the third embodiment, a series of operations are all automatically and reliably performed, and the operator can perform the rotating operation at the fluid supply source. Since it is sufficient, neither the direct operation nor the remote operation is required for each discharge port E, and the complete III operation over the entire operation operation can be performed. In addition, since the supply fluid is discharged from the discharge port E via the cylinder 11, the fluid supply pipe to the device needs only one pipe for the fluid to be discharged, and the work for driving the discharge port E is required.も な く There is no need to separately supply the fluid or to separate it afterwards. Of course, there is no need for a 1E source, and there is a special advantage in that it can be easily standardized and manufactured at low cost.

Other configurations and operation modes are the same as those of the third embodiment, and thus detailed description is omitted. The fifty-first embodiment relates to the fifth embodiment of the present invention, in which the work of the piston 2 in the fourth embodiment of the present invention is reversed. Then, the K with the pilot unit ^ C is transformed and the pre-engagement engagement part 31 is also transformed into 笫 丄: ίΐ embodiment type iii.駆 動 駆 動 駆 動 駆 動 駆 動 駆 動 駆 動 駆 動. From the fourth example, the support for the power of Sakugawa to the graph is changed from the one in the fourth example, and Sakukawa j I iij is inverted '| !; Other configurations and modes of encouragement are the same as those in the four examples and M, so the explanation is omitted.

 The sixth fx | is a small version of the 笫 6 ^ example of water, and the pilot 装 of the fourth '' s example is mounted on Biston 2 This is an example of |

 In the present embodiment, the speed of the piston 2 and the pilot device C is adjusted by bringing the mouth J. 6 of the pie mouth device ilC into contact with the upper and lower lids of the syllabus 1. The spring 32 attached to the end of the rod 16 is equivalent to the urging means 32 of the pre-engagement engaging portion 31 in the fourth embodiment. The rod 16 of the pilot mounted ItC is pulled into the valve seat 21 and separated from each other by suddenly moving the rod 16 when the acting force from 2 is accumulated and the specified limit is exceeded. It plays the role of a kind of toggle switch, making alternatives and clarifying the operation.

 It is noted that the passage p5 from the chamber g2 of the pilot device C to the cylinder chamber e2 once goes out of the cylinder 1 and is blocked again by the cylinder chamber e2 because of the flow control means 45. Is made possible from outside.

 The other rotation and operation modes are the same as in the case of No. 4 rushing, so detailed description is omitted.

 FIG. 7 shows a seventh embodiment of the present invention, in which the communication pipe from the chamber g2 of the pilot device C of the sixth embodiment to the cylinder e2 is omitted. This is an example in which the structure is further simplified by opening the inside of the cylinder chamber e2. In this case as well, it is preferable to provide a flow control means 45 instead of simply releasing 1 ° because the decomposition can be performed by disassembling the skin.

 Other configurations and operation modes are the same as those in the sixth embodiment, so detailed description will be omitted.

The eighth ^ is a small version of the eighth embodiment of the present invention, which illustrates the typical aggressiveness of the device i of the present invention, and which is released from the drive device SB to E. Like-is an example. Driving force iz ^ i! The pantograph, which is exemplified as a machine f D, is not only a rapid train like I, but also a -row, a snake, etc. Each i (is known and may be selected for i.

 The other aspects of the composition and operation are the same as in each of the examples, so the explanation is omitted. Immediately, in the ninth embodiment of the present invention, the driving force is transmitted from the drive KB to the 1 ': Ι as an example of the driving force description machine D via a pulley 52 and a wire 53. FIG. 10 shows a tenth embodiment of the present invention, in which a rack-pinion is used as another example of the driving force transmission mechanism D. After converting to II rolling force, the portable wire 55 is unwound or unwound from the drum 54 and released: an example of driving the IE support member 51 is shown. It is a thing. In both embodiments, the support member 51 is shaped like a telescope, and the movement is further increased by combining the pulleys, gears, levers, etc. It is also possible to expand and contract more by expanding the width or increasing the number of nests of the support member 51. In addition to the above, various types of motion mechanisms of the support member 51 such as the above-described pantograph and other telescopic arms are well known, and may be appropriately applied according to use conditions. Each example is omitted.

Note that these 9, for driving instrumentation ^ B of the first 0 embodiment, as the work moving direction of the piston 2 of the seventh embodiment mosquitoes those that have been in the opposite ^direction? Is illustrated. Along with that. The operation direction of the valve element 21 of the pilot device C is also reversed from that of the seventh embodiment, and therefore, a spring is mounted between the valve element 21 and the centrally located valve ¾. The body 21 is always urged in the valve direction.

 Although illustration is omitted, a bypass pre-passageway is provided between the inlet flow passage a and the outlet flow passage b, and by adjusting the bypass flow, it is possible to reduce the degree of the royal edict of Biston 2. The ιϊίί note of each 'example and j-sama.

Other configurations and operation modes are the same as those of the Ji Example, and detailed description is omitted. The 11th M is an example of the first embodiment of the present invention, and the seventh embodiment is the f-type including the biston 2 itself of the embodiment. It is something. In this case, the concealing member 2 is connected to the piston 2 of 7 examples for ^one J 4 e 1, and; 'e2, which is connected to'! —F. V by passage p 7 and the through hole, is connected to the cylinder of the seventh embodiment, e 1; Wire 13 attached to the liij between the rod 21 of the pilot unit C and the bottom of the drive ¾H¾B, and the ^ contact point 3 between the outside of valve 21 and the bottom of the drive B 3 Reference numeral 1 corresponds to the continuous excitation engaging portion 31 of the seventh embodiment.In the forward movement stroke of the separating member 2 (upward in the figure), the nesting type is mutually sealed by the sealing portion 2s. As the partition member 2 rises and expands due to the internal pressure of the chamber e1, the volume of the chamber e2 is reduced and the internal pressure is increased, and the internal fluid is pushed out to ¾: out irJ E, and the end of the forward stroke At the point in time, the suction from the valve seat was pulled off by the stretched wire 31 from the valve element 21 of the pilot device C, and the chamber e 1; e 2 and the discharge port E were all in communication. Provided The return stroke of the partition member 2 is started by the urging means (i-weight of the partition member 2 in this embodiment), and the fluid in the chamber el flows out toward the discharge port E via the chamber e 2 as it is. In this way, the same operation as in the seventh embodiment is performed, and it is more preferable to provide a wire 3: [a tensioner for preventing slack is provided.

 Other configurations and operation modes are the same as those of the seventh embodiment, and thus detailed description is omitted. FIG. 12 shows the 12th embodiment of the present invention, and nesting of the 11th embodiment is shown. This is a simplified version of the seal portion 2 s of the partition wall member 2 of the formula. In this embodiment, since e 2 does not decrease in width in the forward stroke of the partition member 2, the fluid does not flow out of!流出 The spill only occurs during the moving stroke.

 Other configurations and operation modes are the same as those in Example 1) :). $> 13 I is one example of a new ^ channel system incorporating water discharge 流体 J: J An example of a suitable river for upland irrigation. Is set up in the present invention, and it is designed to spray liquid suspension while I descends dynamically.

Ai, In this example, one example of the use of 0Ϊ in upland irrigation is Then, if you try to pass through the body after passing through the liquid rest, the path is cut off (hereinafter referred to as “liquid closing valve”). The system is designed to extrude the remaining liquid in the water by compression.

 The function of the liquid opening / closing valve F is as follows: When the spraying power of the chemical solution ends, the supply source is switched from liquid supply to air supply, compressed air is injected into the pipe 8 Ε, and the residual liquid is released all at once. When the fluid is discharged from each fluid discharge device に, the fluid discharge device A, in which the residual liquid has been completely discharged, closes the liquid open / close valve F and the air discharge stops dynamically, causing a loss of air pressure. It is to prevent. As the liquid open / close valve used for this purpose, those described in International Application PCT / JP01 / 03762 are preferred. The interposition position it may be on the inlet flow path side of the fluid discharge device iA as shown in the drawing. There is also a method of interposing the output flow path side of the fluid discharge device A, that is, immediately before the discharge port.

By operating and controlling the valve, the liquid opening / closing valve F at each terminal of the pipeline 81 automatically responds, so that a single pre-translation from the liquid supply dispersion to the complete dispersion of the residual liquid Operation with-Only control is possible.

Specific operation顺is, for example ^ liquid Ji ^ to ¾ ^ in is the first state - feeding late cloth - Okueki俘: A feeding ¾ scatter the remaining ¾ liquid by - sending ^^ _il: - Popular ^ release允 Closed F is returned to the initial state. Repeat this process with the water sprayer.

Not only can I prevent it, but also water and-old] It is possible to prevent the shadows (both of which become effective or one wash away the other) due to the liquid remaining in the path. It is a river. Note that the i operation ^ 顺 is an example, and it is needless to say that it is not necessary to limit to this ^ 顺.

 The operator of this pipeline system only needs to perform the operation at the source of the liquid supply and air supply, and neither the direct operation nor the remote operation is required for the fluid discharge device A and the liquid opening / closing valve F at the line terminal. Therefore, there is no need for any control pipe and control wiring for this purpose, and this is a circuit system that can easily and economically perform medium control. Each of the on-off valves 64, 68, and 70 can be automated by attaching an actuator or the like in place of the automatic operation. Further, the operation procedure is controlled by a timer or a sequence control. It can be automatically controlled by the control device 71 to perform the entire process completely!

 Depending on the operating conditions, a flow rate and pressure dynamic adjustment valve, exhaust valve, safety valve, check valve, storage valve, various instruments and control devices may be provided in the middle of the pipeline. Also, as power for the water supply unit and air supply unit, an engine is connected, or the vehicle is connected to the power of a vehicle such as a car or a tractor. By doing so, it is possible to operate the vehicle in places without power.

 Next, technical matters common to each of the embodiments will be described.

As for the biasing material used in steps 4; 1 8; 3 2, compression springs or tension springs may be selected as appropriate, and it is not necessary to select the type of material that will be used. For example, instead of the coil spring, another type of spring or elastic part may be used instead of the coil spring, or it may be housed in a spring case. Further, as the biasing force, one of the forests may be Icheon, the weight may be set to 1 /, the liquid supply device may be set to an appropriate river, or a power mechanism may be added. It is needless to say that the position ί; 'does not need to be limited to the indicated ί,' / :. 1 Note that il is omitted, but if the biasing force of these biasing force stages 4; 1 832 is made to be an adjustable I 'function, the fine setting can be conveniently changed to a dinging function according to the conditions of use. The method is not known, such as the method of adjusting screws.

 Sealing parts mounted on ft places requiring hermeticity, such as the sliding parts of the piston 2 and the cylinder 1 and the valve body] 12; 13; 14; 15; 21; O-rings, packings, seal rings, diaphragms, bellows, etc. may be appropriately ffled, or other elastic members may be attached, and good direct contact may be applied. If the sealing property can be maintained, the sealing member may be omitted. The combination, arrangement relationship, and mounting position of each component of the fluid discharge device and the pipeline system of the present invention need not be limited to the illustrated example, and can be appropriately selected in design.

 The interlocking direction of the discharge port E is not limited to the F direction as shown in each embodiment, and may be appropriately designed according to usage conditions such as the left and right direction and the rotation direction. Sprinklers, perforated pipes, nozzles, etc. may be attached to the end of the outlet E according to the form of discharge. In particular, when performing uniform fluid distribution over a wide range, the injection direction is automatically adjusted. It is preferable to attach an H-motion sprinkler device or the like that changes the pressure.

 Although the application of the present invention has been described as an example of the application of upland irrigation, the present invention is also applicable to other fields, such as domestic rivers, and other fields. It is not limited to the previous example.

 In addition, within the scope of the spirit of the present invention, fffl can be changed, 义, the support of the conventional technology can be used for each component element, and the book W can be changed to ^. To
