Description

69 298569 A7 B7 V. Description of the invention (1) Background of the invention: (1) Field of the invention: The present invention relates to a liquid sprayer, especially a spray head of a liquid sprayer. The liquid sprinkler in this case is also suitable for protecting typical crops, trees, etc. from frost. (2) Related conventional skills: At present, sprinklers have been used to spray water outdoors, such as farms or vegetables used to grow vegetables or flowers, flower gardens, greenhouses or flowers, fruit gardens, public gardens with flowers or grasses, or road. Generally, the sprinkler is provided vertically in the center of the desired sprinkling area, and the water is spouted out through the nozzle formed in the rotatable sprinkler head, and the water spouted through the nozzle will hit the impeller mounted on the head, Due to its impact force, it can rotate the head in one direction and spray water concentrically in a wide range. However, the sprinkler heads of the above-mentioned conventional sprinklers produce a central (ring-shaped) spray area, which is centered around the sprinkler, as shown in Figure 7 3, in which the spray pressure zone is caught The diagonal area of the sprinkler 11. That is, when the desired spray area is a rectangular or square certificate area, water cannot be sprayed to the corners of the area. In addition, although the sprinkler can spray water in a wide area, it cannot spray the water in the area close to the sprinkler. If you want to spray water on the entire spraying area, you must provide the spray area of the overlapping part of the sprinkler, as shown in 圚 74, in which the sprayer 1 1 is provided so that the diagonal part of the overlapping part can be sprinkled region. That is, there is another problem that the sprayer cannot be effectively provided in a spray area. (Please read the precautions on the back before filling in this page) d The paper size of the binding and binding book applies to the Chinese National Standard (CNS) Α4 specification (_2 丨 0 侂 297mm) A7 _B7____ V. Invention description (2) In addition, The sprinkler head of the conventional sprinkler has a nozzle with a nozzle diameter of more than 2 mra to obtain an effective impact force, so it is inevitable to form larger spray water droplets. That is, a strong impact force is exerted on the surface of the spray area by the larger water droplets. Since the water droplets will bounce back, the water cannot be gently sprayed. When water is sprayed onto the surface of the sprayed BE field to hit the surface, the sown seeds will flow away from the soil, or the roots will be exposed outside the soil, causing serious problems that hinder plant growth. In addition, when water is sprayed on the vegetables or flowers planted in the ridges of the classic field, or trees planted linearly, inevitably the ground water will be sprayed into the ditch between the ridges, or a row of trees and another The space between a row of trees, that is, the water will be sprayed to the area not to be sprinkled, so a larger amount of water will be required. In other words, it will waste a lot of water. When the desired spray is not on a horizontal plane, that is, when the water is sprayed to an inclined plane, the spray distance between the water droplets and the sprayer provided vertically in the center of the inclined plain, on the inclined The lower side of the plain is different from the upper side, so the water cannot be sprayed evenly across the inclined plain. In addition, on the upper side of the inclined plain, the water droplets sprayed through the nozzle will inevitably hit the soil surface, because the sprinkler is closer to the soil surface. Thus, for example, the seeds sown will flow away from the soil, the leaves or trunks will be damaged, or the roots will be exposed outside the soil, causing problems that hinder plant growth. In addition, as mentioned above, the sprinkler sprays water from the rotating head. Only by the specific rotation angle of the sprinkler head can the spray fan's spray fan garden be changed. It is impossible to control the spraying of many waters spraying the HE domain. That is, the watering area is always limited to the fan-shaped seedling area, or the semi-circular area with the sprayer position as the paper scale. The Chinese national standard (CNS) A4 specification (210X297 mm) is applicable (please read the back side first (Notes and then fill in this page). Binding-Order A7 B7 298569 5. Description of the invention (3) (please read the notes on the back before filling in this page). It is the center of mind and can only change the rotation angle of the spray head. . However, the actual change of the rotation angle fan garden has a technical difficulty because, for example, the balance between the rotation angle fan garden and the water feed speed must be accurately adjusted first. Therefore, when the water spray area is part of the entire surface area of the stern sprinkler position, the sprinkler is located on the side of the sprinkler position (such as the west side of the sprinkler position), or when the water is sprayed The sprinkling area is on both sides of the sprinkler position (that is, the entire area around the sprinkler position), but this water sprinkling area is located at or close to the sprinkler position, there will be a problem It is not possible to effectively spray water on only a part of the area. In general, agricultural crops such as beans, bells, vegetables, maize, tea, coffee beans, mulberry leaves, pastures, etc., and fruit trees such as grapevines, tangerines, etc. are susceptible to frost damage in the early frost of autumn or late frost in spring. The formation of frost is due to the contact of water vapor in the air with objects on the soil surface or the ground and continuous sublimation. That is, frost damage is a physical climate disaster due to low temperature. Therefore, at present, the following measures are taken for frost damage, for example in orchards, tea gardens, mulberry traps, etc .: (1) planting frost-proof frost trees; (2) wrapping plants with plastic sheets; (3) air in gardens and farms must Heat or fan to fan the wind, etc .; (4) Must be buried, or must be sprayed with water droplets or antifreeze to avoid frost and so on. Among these measures, spraying water droplets is easy to perform due to very low labor, low cost, and low investment. Therefore, attempts have been made to use a sprinkler as a device to prevent frost damage, because they can inhibit the generation of frost. However, the head of the conventional sprinkler sprays water through a nozzle to hit the wheel, and by The impact of the sprayed water is used to rotate the spray head. The specifications of the Chinese National Standard (CNS) A4 (210X297 mm) are applicable to this paper standard. _ 6 _ A7 B7 5. Description of the invention (4) is the water droplets sprayed The size of the water droplets is so large that they cannot be suspended in the air for a long time and will fall immediately, and effective heat exchange between the water droplets and the air cannot be performed. As mentioned above, the water spray area of the sprinkler head is a surface area with a center (ring-shaped), surrounded by a sprinkler. That is, water spraying can be performed over a wide area, but water spraying cannot be performed in the area close to the leaker. Therefore, the distribution of sprayed water is not uniform in the entire spraying ffi field, and the effect of avoiding frost damage is poor. The problem with the spray heads of conventional sprayers is that they are less effective in avoiding frost damage. In addition, the conventional sprinkler is provided with a filter in the discharge outlet of the pump used to feed water to the sprinkler, or in the water supply pipe connected to the discharge outlet of the pump to avoid sand, rust, dust, etc. Caused it to block. However, the discharge outlet of the pump providing the filter or the water supply pipe connected to the discharge outlet

• ^ I, its diameter is very small, so the filter provided in the liquid channel cannot have a child's mesh. As a result, there will be problems such as large M drop, restricted flow rate, and clogging by sand, rust, and dust. When a conventional sprinkler is used in the fruit bowl, the water droplets from the nozzle to the vane are spread above the spray head and are attached to the fruit, so the fruit is kept in a fixed wet state. As a result, they are easily susceptible to so-called pathogen infections, such as the growth of microbes and bacterial infections on fruits, thereby reducing the quality and production of fruits. When using a conventional sprayer in a greenhouse farm or garden, the angle of the mouth must be lowered so that the water droplets sprayed from the mouth will not hit the ceiling of the greenhouse. In other words, the height of the spray will be limited. In other words, the water droplets sprayed from the nozzle act on the soil surface and cause a large impact on the soil surface, which causes the water droplets to rebound and cannot be carried out.

^ 98569 A7 B7 5. Description of the invention (5) Mild water spray. In other words, the problem with the conventional sprayer is that it is impossible to spray water without considering the so-called spray height limitation. Therefore, there is an urgent need for a sprinkler head that can spray water in any shape and size of the spray area under the limitations of the so-called sprinkler head, and can be well applied to orchards, greenhouse farms or gardens. SUMMARY OF THE INVENTION: The object of the present invention is to provide a liquid sprinkler without the aforementioned problems of the conventional technology. Another object of the present invention is to provide a liquid sprayer capable of spraying liquid substantially uniformly and gently over the entire spray surface area of any desired shape and size. Another object of the present invention is to provide a liquid sprayer capable of spraying a liquid hip substantially uniformly on an inclined spray area, that is, on an inclined plain. Still another object of the present invention is to provide a liquid sprayer capable of spraying smaller droplets substantially uniformly over the entire spray area, so that the droplets can be suspended in the air for a longer period of time, thereby effectively The heat exchange between the droplets and the air, that is, the liquid sprayer can be used stably as a device to avoid frost damage. According to the present invention, a liquid hip choke sprinkler is provided, and a vertical window is placed at a desired position in a desired liquid sprinkling area. The liquid «sprinkler includes: (1) a rise pipe (rise pipe), Vertically set at the desired position in the desired liquid hip spray area: (please read the precautions on the back before filling in this page) • Binding · Order the alpha line paper size is applicable to the CNS Α4 Grid (210Χ297mm) ^^ 85β9 Α7 ___ Β7_ V. Description of the invention (6) (2)-Upwardly protruding, generally hemispherical, sprinkler head, with many nozzles capable of spraying liquid to the desired spray area, this The sprinkler head is installed on the top of the riser in an attachable manner: and (3)-Dispenser, connected to the lower end of the riser. According to the first aspect of the invention, the sprinkler head is a type of sprinkler head that can determine the spraying distance of the liquid skull by selecting the nozzle diameter, the angle of the nozzle, and the liquid pressure on the nozzle; the angle of the nozzle is selected In the range of 2 0 ° to less than 90 °; the diameter of the nozzle is selected in the range of 0.1 nun to 2 mra; and can change the pressure of the liquid on the nozzle to the desired pressure. It is located in the pipette or riser. I · Since the desired liquid «spraying distance can be set by selecting the nozzle diameter, the angle of the nozzle, and the liquid pressure on the nozzle, the spraying distance of the liquid hip can be changed, for example, according to the shape and size of the spraying area, thereby The liquid can be sprayed substantially uniformly over the entire spray area of any shape and size. Since the angle of the nozzle is selected within the range of 20 ° to less than 90 °, the liquid sprayed through the nozzle under the selected liquid pressure will not hit the soil surface of the spray area. Therefore, the sprayed droplets will not bounce back, and the liquid can be sprayed gently. '1-Since the diameter of the nozzle is selected in the range of 0.1 mm to 2 nm, the smaller droplets are sprayed from the nozzle, so the impact of the droplets acting on the surface of the pressure zone is small . Therefore, the sprayed droplets will not rebound from the surface of the soil, and the liquid can be sprayed gently. Since the liquid pressure changing device capable of changing the liquid hip pressure to the desired pressure is provided in the pipe or riser, for example, according to the shape of the spray area (please read the precautions on the back before filling this page) d The paper size of the binding book is applicable to the Chinese National Standard (CNS) A4 (210X297mm) ^^ 85β9 Α7 __Β7_ V. Description of the invention (7) When the shape and size are used to change the liquid spraying distance, the nozzle diameter and nozzle can be increased The degree of freedom of the angle can greatly ensure that the liquid can be sprayed substantially uniformly on the entire spray area of any shape and size. According to a second aspect of the present invention, the sprinkler head has many open mouths, formed along a number of imaginary lines crossing at the apex of a substantially hemispherical sprinkler, and has a roughly diameter on the surface of the substantially hemispherical sprinkler A nozzle that extends toward the ground and is formed along the same imaginary line has an increased diameter as the distance between the nozzle and the vertex increases. Since many nozzles are formed along an imaginary line that crosses the apex of a substantially hemispherical sprinkler head, and extends substantially radially on the surface of the substantially hemispherical sprinkler head, the The nozzle position on the surface of the head can set the liquid spraying distance, and by changing the pattern of many imaginary lines on the surface of the substantially hemispherical spraying head, the liquid can be sprayed according to the shape and size of the spraying area. Since the nozzles formed along the same imaginary line have an increased diameter as the distance between the nozzle and the apex increases, the liquid skull can be sprayed on the entire spray surface area approximately uniformly, whereby Spray the liquid almost evenly over the entire spray area of any shape and size. In addition, since the liquid sprayer in this case can be effectively distributed, the number of liquid sprayers used in a given spray area can be less than that of the conventional liquid sprayer. According to the third aspect of the present invention, the sprinkler head has a number of nozzles formed along the first imaginary suspicion defined by the opposite sides of the polygons of the apex of the substantially hemispherical sprinkler head in the envelope. The first hypothesis defined by the opposite side is the sticking of the top of the sprinkler head, which is bent to a roughly hemispherical shape. For example, from the vertex, the paper scale is applicable to the Chinese National Standard Rate (CNS) A4 specification (210X297mm) -10-(please first Read the precautions on the back and fill in this page) ό -installed 1 * 1Τ line A7 B7 5. Invention description (8) The plan view of the roughly hemispherical sprinkler on the side, and the nozzle is also along the second imaginary line Formed, the second imaginary line is parallel to the first imaginary line but closer to the vertex; the polygon is a diamond; and the nozzles formed on the same imaginary line have equal nozzle diameters. Since many nozzles are formed on the surface of the substantially hemispherical sprinkler head, along the first imaginary line defined by the opposite sides of the polygon surrounding the vertex of the substantially hemispherical sprinkler head, this is defined by the opposite side of the polygon The first imaginary line defined is the vertex of the substantially hemispherical sprinkler head, as shown by the plane circle of the roughly hemispherical sprinkler head from the vertex side, and the nozzle is also formed along the second imaginary line. The second imaginary line is parallel to the first imaginary line but closer to the vertex, so the desired liquid distance can be set by the nozzle position on the roughly hemispherical spray head, and by selecting the shape of the polygon, for example The pattern of imaginary lines on the surface of the roughly hemispherical sprinkler head can be based on the shape and size of the spray area. Therefore, in any: ^. Ik meaning the shape and size of the entire spray area, the liquid spray can be sprayed substantially uniformly, and because the liquid «sprinkler of this case can be effectively set up, in the given spatula in the western region The number of liquid sprinklers used can be less than that of the conventional liquid-spraying devices. Since the polygon is a rhombus, the liquid can be sprayed on the entire area of the spray area, such as a rectangle or square, substantially uniformly.

I Since the nozzles formed on the same imaginary line have equal nozzle diameters, a more uniform liquid spray can be obtained over the entire spray area of any shape or size. According to the fourth aspect of the present invention, the sprinkler head has many nozzle formations (please read the precautions on the back and then fill out this page) α. 装. Threading & This paper scale uses the Chinese National Standard (CNS) Α4 specifications ( 210Χ297 mm) -11-A7 B7 V. Description of the invention (9) In a strip-shaped area, this strip-shaped area is defined by two second imaginary lines parallel to the first imaginary line, and is roughly hemispherical The apex of the sprinkler head, as shown in the plan view of the roughly hemispherical sprinkler head from the apex side; at least one band BE field is located on each side of the first imaginary line: and the band region is located on the sprinkler In the vertical section of the head (that is, the section through the apex), the angle range from the center of the roughly hemispherical sprinkling head is 0 ° to 8 5 ° and is perpendicular to the first imaginary line. Since many mouths are formed in a band-shaped area, the band-shaped ffi domain is defined by two second imaginary lines parallel to the first imaginary line, passing through the apex of the substantially hemispherical spray head, such as from the apex The plan view of the generally hemispherical sprinkler head on the side is shown, so by the nozzle position on the surface of the generally hemispherical sprinkler head, the desired liquid spraying distance can be set, and for example by changing the pattern of the banded area , According to the shape and size of the spray area, I- spray the liquid value. Since the nozzle is formed in the band-shaped BE domain, the liquid will not be sprayed to the area where the liquid is not sprayed. Thus, the spray of liquid can be reduced. That is to say, it is possible to reduce the waste of "Jian." Since at least one band-shaped tt field is set on the side of the first imaginary line, by vertically arranging a liquid skull sprayer between the two geyser fields, the liquid skull can be sprayed simultaneously from a spray head Sprinkle to two spraying areas ° The strip-shaped seedling field is a vertical section of the sprinkler head (that is, a section through the apex), and the angle range from the center of the roughly hemispherical sprinkler head is 0.

Description of the invention (10) The angle of the nozzle increases and decreases. Therefore, the sprayed droplets can be gently sprayed to the surface area without spraying back from the soil surface. When using the liquid sprinkler of this case to spray water under the scaffold of fruit trees, such as Portuguese Portuguese trees, it is best that the strip area has a low elevation angle, and the best range of elevation angle of this strip area is 0 ° to 60 °, by selecting the smaller nozzle diameter of the band-shaped area, the impact of the sprayed droplets on the soil surface of the spray area can be weakened. According to a fifth aspect of the present invention, the sprinkler head has a number of nozzles formed in a rectangular area, the rectangular area is formed by two first imaginary lines that are substantially parallel to each other, and intersect each other at a right angle to the first imaginary line The two second imaginary lines parallel to each other are enclosed by a garden, as shown in the plan view of a substantially hemispherical sprinkler head from the vertex side, the vertex is located in a rectangular area: this rectangular M domain is located perpendicular to the sprinkler head In the profile (that is, the profile passing through the apex), the range of suppression angle to the center of the roughly hemispherical sprinkler head is 30 ° to 90β, and is perpendicular to the first imaginary line, and is also set in the vertical section of the sprinkler head (That is, the section through the apex), the range of suppression angle with the center of the roughly hemispherical sprinkler head is 30 ° to 90 ° and is perpendicular to the second imaginary line. Since many mouths are formed in a rectangular area, the rectangular area is formed by two first imaginary lines that are substantially parallel to each other, and two second imaginary lines that intersect the first imaginary line at substantially right angles and are parallel to each other The package garden, as shown in the plan view of the roughly hemispherical spray head from the vertex side, the top spot is located in the rectangular area, so the liquid «can be sprayed upward from the spray head, so it can be sprayed throughout the desired The liquid hips were sprayed on the BE field roughly evenly. By selecting the diameter of the nozzle, the sprayed droplets can be made smaller, and the droplets can be suspended (please read the precautions on the back before filling out this page) α Pack. The paper size of the binding book is applicable to the Chinese National Standard (CNS) Α4 wash grid (210Χ297 mm) -13-_B7_ V. Description of the invention (11) 1 In the air for a long period of time, thereby allowing sufficient heat exchange between the droplets and the air. That is, frost damage can be effectively avoided. In other words, the liquid «spill sprayer '' in this case can be effectively used as a device for avoiding frost damage. In addition, since the nozzle is formed in a rectangular area, the liquid will not be sprayed downward only from the spray head. Therefore, it is possible to reduce the body weight of the hips by spraying the liquid. In other words, it is possible to reduce wasted liquid. Since the sprinkler has no moving parts, it is not afraid of the trouble and failure of moving. 'Because the rectangular area is set in the vertical section of the sprinkler (that is, the vertical section through the apex), the range of the angle of inhibition with the center of the roughly hemispherical sprinkler is 30 ° to less than 90 °, and is the same as the first Imaginary vertical, and at the same time I 1 1. Also in the vertical section of the sprinkler head (that is, the vertical section through the apex), the angle of inhibition with the center of the roughly hemispherical sprinkler head is 30 ° to less than 90 ° and perpendicular to the second imaginary line, so the liquid can be completely and completely sprayed upward from the sprinkler head, so that the sprayed p droplets can be suspended in the air for a longer time, thereby between the droplet and the air There is sufficient heat exchange between the two. According to a sixth aspect of the present invention, the sprinkler head has a plurality of nozzles in two divided ffi domains of a substantially hemispherical sprinkler head, and these two divided areas are imaginary being passed through the apex of the substantially hemispherical sprinkler head The lines are divided, and the nozzles in one of the divided areas have a denser nozzle distribution as the distance from the apex increases, while the nozzles in the other divided area have the increased distance from the apex. It has a relatively sparse nozzle distribution, or the sprinkler head has a nozzle formed in an area, this area is defined by two second imaginary lines, and the two second imaginary lines and the sprinkler head passing through the hemispherical shape The top d G --.— ^ ----- f ------ ir ------ 0 (Please read the precautions on the back before filling in this page) Standard (CNS) A4 specification (2 丨 OX297mm) -14-B7 V. Description of the invention (12) The first hypothetical line at the point intersects at a right angle, and the two second hypothetical lines are roughly parallel to each other: This area is further divided into two sub-domains with the first imaginary line: each divided 1S domain is divided into an imaginary ellipse It is divided into two sub-steps in one step. The imaginary cabinet circle is drawn with the line between the intersection of the first imaginary line and the two second imaginary lines as the upper line: the imaginary cabinet garden in one of the sub-regions The nozzles in the outer secondary part have a total opening area that is larger than the nozzles in the secondary part inside the imaginary ellipse, and the nozzles in the secondary part outside the imaginary ellipse in the other secondary domain have a total The opening surface is smaller than the nozzle in the secondary part inside the imaginary ellipse. Since many nozzles are formed in two divided surface areas of a substantially hemispherical sprinkler head, the two divided ffi areas are divided by an imaginary straight line passing through the apex of the substantially hemispherical sprinkler head, in one of the divided areas The nozzle in has a denser nozzle distribution as the distance from the vertex increases, while the nozzle in the other divided area has a sparse nozzle distribution as the distance from the $ point increases. In the case of an inclined spray area, that is, when the liquid is to be sprayed onto an inclined plain, the spray head must be installed on the riser, so that as the distance from the top increases, there is a denser nozzle The divided area of the distribution may face the lower side of the sloping plain, and the liquid hip «稹 sprayed to the lower side of the sloping plain is larger than the liquid« hip puff sprayed to the upper side of the inclined plain. By this nozzle distribution, the nozzle position on the approximately hemispherical spray head can determine the desired liquid hip spray distance, so the liquid can be sprayed approximately uniformly on the desired inclined spray area. Since the sprayed droplets can be made smaller by selecting the nozzle diameter, the impact force of the sprayed liquid "on the soil surface will be smaller (please read the precautions on the back before filling in this page)

Therefore, even on the upper side of the inclined plain, the droplets do not strongly hit the soil surface. In other words, the droplets that can be sprayed gently and the sprayed liquid will not return from the surface of the soil. For example, the sown seeds will not run off the soil or damage the trunk, or the roots will not be exposed outside the soil. In other words, I'm not afraid of hindering the growth of plants. Therefore, the liquid sprayer in this case was used to spray the liquid hip to the inclined plain. " Since many nozzles are formed in an area, this area is defined by two second imaginary lines, which are roughly the same as the first imaginary straight line passing through the vertex of the roughly hemispherical sprinkler Intersect at right angles, and the two second imaginary lines are roughly parallel to each other; this area is further divided into two sub-areas by the first imaginary line; each divided area is divided into two by one imaginary grid circle In this sub-section, this imaginary ellipse is drawn with the line between the first imaginary line and the intersection of the two _ second imaginary lines as the upper line: the secondary outside the imaginary grid circle in one of the sub-areas The nozzles in the part have a total opening surface pitch greater than the nozzle in the secondary part inside the imaginary cabinet, while the nozzles in the secondary part outside the hypothetical ellipse circle in another sub-region have the total opening surface pitch less than The nozzle in the secondary part inside the imaginary ellipse, so in the case of an inclined spray area, that is, when the liquid is to be sprayed on an inclined plain, the spray head must be installed on the riser , Making the nozzle in the imaginary ellipse The total opening in the secondary part on the outside is larger than the total opening in the secondary part on the inner side of the imaginary cabinet circle. The secondary area will face the lower side of the inclined plain, so it will be sprinkled to the inclination. The volume of the liquid on the lower side of the plain is larger than that of the liquid carp sprayed on the upper side of the inclined plain. With this nozzle distribution, it can be hidden by the mouth on the roughly hemispherical head (please read the precautions on the back before filling out this page)-The paper size of the binding and binding book is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -Ifi · A7 B7 V. Description of the invention (14) Set the required liquid spraying distance, so that the liquid can be sprayed more uniformly on the entire inclined inclined spraying area. According to the seventh aspect of the present invention, the sprinkler head has many nozzles formed along many concentric lines, and the concentric lines are centered on the apex of a substantially hemispherical sprinkler head, and along the same The nozzle formed by the center line has an increased diameter as the distance from many imaginary lines increases. The imaginary line extends radially from the top to the surface of the substantially hemispherical spray head: The imaginary line is four lines Intersects adjacent lines at right angles; nozzles formed along the concentric line on the surface of the roughly hemispherical spray head have an increased total nozzle opening surface as the distance between the concentric line and the apex increases Zhen. That is, the nozzle is formed along a concentric line centered on the apex of a substantially hemispherical spray head, and has an increased diameter as the distance from many imaginary lines increases. This imaginary bran is roughly radial from the apex Extends on the surface of a substantially hemispherical spray head. In other words, the diameters of the nozzles along the same center line are not equal to each other, that is, the diameter is the smallest at the position closest to the imaginary line, and the largest at the position closest to the imaginary line. Since the nozzles have different diameters, depending on the distance from the imaginary line, the spraying distances of the droplets ejected from the nozzles are different from each other. Therefore, the spleen-shaped spray field formed by the conventional liquid pith sprayer can be changed to the desired shape◊ That is, by adjusting the diameter of the nozzle formed along the same center, the diameter can be changed The liquid "sprays onto any desired spray area." The liquid skull can be sprayed on the entire spray surface area of any shape and size as desired. In other words, the liquid hip sprayer in this case must be placed vertically according to the shape of the spray area, because the liquid sprayer in this case can take the liquid skull (please read the precautions on the back before filling in this Page) ό-装. * 1Τ Line paper ruler is applicable to China National Standard (CNS) Α4 specification (210X297mm) -17-A7 B7 5. Invention description (15) Sprinkle on any shape of the surface area. In addition, since the liquid sprayer in this case can be effectively installed, the number of liquid II sprayers installed on the entire spraying area will be less than that of the conventional liquid sprayer. In addition, the imaginary line is four lines each intersecting the adjacent line at right angles. When nozzles with equal diameters are formed along four imaginary lines, and the diameter of nozzles formed along the same center line has an equal increase ratio according to the distance from the imaginary line, the liquid can be evenly sprayed to the square The spray area of 0 is due to the nozzle formed along the concentric line on the surface of the roughly hemispherical sprinkler head, and has a total nozzle opening area which increases as the distance between the concentric line and the vertex increases. Between the area of short spraying distance (that is, the area close to the liquid sprayer) and the area of the long spraying distance (that is, the area that catches the liquid sprayer), each unit The sprayed liquid body of the Zhen Zhen can be made uniform, so that the liquid spray can be performed substantially uniformly over the entire spray area. According to the eighth aspect of the present invention, the sprinkler head is provided with a spray prohibition component for prohibiting spraying of liquid through nozzles other than the nozzle specified by the desired spray area, and the spray head is provided with a sealing member, Used to prohibit the isolation between the sprinkler components and the sprinkler head. Since the spraying liquid hip can only pass through the nozzle that is not prohibited by the spraying prohibited member, by selecting the nozzle that should not be sprayed with the spraying prohibited member, the liquid can only be sprayed through the desired nozzle, so the liquid It can be effectively sprayed to the desired spray area of the entire hip area of the liquid hip swab applicator, that is to say, I ', · All areas around the non-liquid sprayer, for example, only sprayed to the liquid spray Sprinkler (please read the precautions on the back before filling in this page) 0.

Description of the invention (16) The spray area on one side, or just spray to the area where the liquid sprayer is faster or closer to the surrounding area. Since the sprinkler head is tightly attached to the spray-prohibiting member by a sealing member, there is no ambiguity between the spray head and the spray-prohibiting member, so when the spray-prohibited member prohibits liquid spraying, it can be avoided The liquid hip remains in the gap between the spray culvert head and the spray prohibited member, or prevents the liquid hip from leaking to the outside through the gap between the spray head and the spray prohibited member. As a result, a more effective liquid can be sprayed with less liquid «. According to the ninth aspect of the present invention, the sprinkler head has a filter between the sprinkler head and the fixing jig, and the filter has a mesh size smaller than the diameter of the nozzle, and a lateral cross section of the riser The noodles are larger and the noodles are filtered. Since the filter has a larger filtering surface than the lateral profile of the riser, the passing surface of the filter can be made larger. That is, the filter can have a larger number of meshes, so it can have a smaller pressure drop without limitation

'-* I feed rate of spraying liquid. Therefore, it is possible to avoid the blockage caused by sand, rust, and dust. Since the liquid can be distributed from the riser connected to the fixture to the entire spray head, the liquid can be evenly applied to the entire spray head, so the liquid can be evenly sprayed to the spray area. According to the tenth aspect of the invention, the sprinkler head has many nozzles, the elevation angle formed between the center of the substantially hemispherical sprinkler head does not exceed 27 °, and it follows many imaginary lines. Extends roughly radially on the surface of 'I.

Description of the invention (17) The total angle of mouth restraint The opening surface of the nozzle is reduced as the elevation angle of the nozzle decreases. Many nozzles are formed on a sprinkler head. The elevation angle of the nozzle to the center of the roughly hemispherical sprinkler head does not exceed 2 7 ° and follows many An imaginary line extending substantially radially from the apex on the surface of the substantially hemispherical spray head. Generally, the spraying distance of the liquid sprayed from the nozzle is best at an elevation angle of 27 °, and the elevation angle of the nozzle decreases or decreases. Therefore, by selecting the nozzle position within a range of nozzle elevation angles not exceeding 27 °, the desired spraying distance of the droplets can be set, and by selecting the pattern of imaginary lines on the surface of the hemispherical part, The droplets can be sprayed to spray areas of any shape and size. Since the nozzle is not formed at a nozzle elevation angle of more than 27 °, droplets will not be sprayed onto the spray head. In addition, the diameter of the nozzle along the same imaginary line decreases as the distance from the vertex increases, so that the liquid can be sprayed substantially uniformly over the entire spray area. That is, the sprinkler head in this case can be well applied to fruit traps, greenhouse farms or gardens under the restriction of the so-called spray height. For example, when the sprinkler head in this case is used for sprinkling water in an orchard, water droplets will not be sprayed onto the top of the sprinkler head, so the water droplets will not adhere to the fruits above, and the fruits above can be kept in a fixed dry state . This results in fewer infections caused by so-called germs, which can maintain the good quality and high yield of the fruit. When the sprinkler head in this case is used in a greenhouse farm or garden sprinkler, water droplets will not be sprayed on the top of the sprinkler head and will not hit the ceiling of the house. That is, the water spray can be carried out without considering the limitation of the spray height specified by Λ.

The number of nozzles 2 is not particularly limited, and the size of the sprinkler head is also not particularly limited. The embodiment according to the first aspect of the present invention will be described below: As shown in FIG. 2, a plurality of nozzles 2 capable of spraying water are formed on the spray head 1, and the spray head 1 is received through a fixing jig 12 Set on the top of the riser 11; by selecting the nozzle diameter, nozzle elevation angle, and water pressure on the nozzle, you can set the desired spray distance of the sprayed water droplets. The riser 11 can be set vertically at the desired position on the soil surface (spray area), but it is best to set it at the center or corner of the spray area to easily select the nozzle diameter and nozzle The elevation angle and the water pressure on the mouth. The diameter of the nozzle is not particularly limited, but the diameter of the nozzle is preferably 0.1 mm to 2 mm. By selecting the nozzle diameter of the above-mentioned fan garden * The water droplets sprayed through the nozzle can be made smaller, and the impact force of the water droplets on the soil surface of the spray j.

If the diameter of the nozzle is less than 0.1 rain, the sprayed water droplets will become very small, so that they will form a domineering shape, so that they cannot successfully cover a long distance. In addition, the amount of water sprayed by each unit will be very small, making it impossible to obtain sufficient water spray in the 1E field. On the other hand, when the diameter of the nozzle is more than 2 πππ, the water droplets will be too large to make the impact force of the water droplets on the soil surface of the spray area become stronger, and the water droplets will rebound from the soil surface, making it impossible to proceed.

Description of invention (25) Elevation angle, due to the water pressure on the mouth, the water droplets sprayed will not hit the soil surface of the spray area. Thus, the water can be sprayed gently without causing the water droplets to bounce off the soil surface. When the elevation angle of the mouth is less than 20 °, due to the water pressure on the nozzle, the sprayed water droplets will hit the surface of the spray area, resulting in an increase in the impact force on the soil surface of the spray area, and water droplets bounce off the soil surface return. Therefore, the water cannot be sprayed gently. ..... In general, it is known that water droplets can advance in the air, resisting the resistance proportional to its speed, so when the elevation angle of the nozzle is set at about 30 ° (the exact value is 27 °) and When the water pressure and the diameter of the mouth are kept fixed, the sprayed water drops can advance to catch more. As for the spraying distance of water droplets, the relationship of Yl / Y2 = 1.4 to 1.5 is established, where Υ1 is the spraying distance when the nozzle's elevation angle is set at 30 °, and Υ2 is the spraying distance when the nozzle's elevation angle is set at 60 ° The spraying distance, water pressure and nozzle diameter are kept constant. In addition, when the water pressure on the nozzle and the elevation angle of the nozzle are fixed, as the nozzle diameter increases and the resulting expansion angle decreases, the sprayed water droplets can advance to catch more. In addition, the spread angle of the water drops increases with the increase of the spraying distance, so the fan garden covered by the spray is widened. That is, when the water pressure on the spray and the diameter of the nozzle are fixed, the spray fan garden narrows with the increase of the nozzle's elevation angle, resulting in an increase in the sprayed water of each unit surface. To roughly keep the water sprayed per unit surface of the "Jing", for example, the diameter of the nozzle formed at the elevation angle of the nozzle at 60 ° is smaller than the nozzle 11 formed at the elevation angle of the nozzle at 30 ° [path.

When the elevation angle of the nozzle a is 30 °, perform a test to determine the diameter of the nozzle a. It is found that when the diameter of the nozzle a is 7m, water can be sprayed to point A. It is known that when the nozzle diameter is fixed, the spraying distance of water droplets at a nozzle elevation angle of 30 ° is 1.4 to 1.5 times the spraying distance of water droplets at a nozzle elevation angle of 60 °, where the distance OA / distance ΟΒ = 7/5 = 1. 4.

In other words, when the nozzle diameter is fixed, If the elevation angle is changed by 30 °, the spraying distance will be changed by 2 m. That is to say, under the above conditions, when the spray of water drops «the distance is within the range of 7m to 5m, the nozzle elevation angle must be increased by 1. 5» to shorten The spraying distance is 10 cm. For example, if the distance OC (# 6.4m) is 0.6m shorter than the distance OA (# 7m), the elevation angle of the nozzle c spraying water to point C will be 39 ° (= 30 ° + 6x1 5 °).

When a test was conducted to determine the elevation angle of the nozzle m with the nozzle diameter set to 0.6 IDID, it was found that at an elevation angle of the nozzle of 70 °, water can be sprayed up to point M. When the diameter and elevation angle of the mouth i to m are set to the above situation, the spray distance of the water droplet at an elevation angle of 50 ° is 4.8m, and the spray distance of the water droplet at an elevation angle of 70 ° is 3. 6m, spray The difference of the spray distance is 1.2 m (= 4.8-3. 6>, so the change of the elevation angle of 20β will change the spray distance of 1.2m.

The leakage density at the overlapping position of the measuring cell, that is, the spray density distribution, is the value obtained by adding the two values of the water depth.

Description of invention (33) By setting the diameters, angles of thought, and elevation angles of the nozzles η and p to s as described above, the results of the water spray test under the same conditions as before, and the water spray test through the nozzles a to m The spraying density distributions of the two overlap, which are shown in Yuqi 4 and 8, respectively, as the spraying density distribution. It is obvious from Figs. 4 to 8 that the entire triangle ΟΑΒ can be sprayed with water droplets from a total of 16 nozzles (nozzles a to η and p to s) with a spray density of about 5 ram to 40 mm. That is, it is possible to gently spray the entire eighth E area of the spray area 1 with water droplets from the nozzles a to s. In Qi 4, there are some blank ® fields, that is, areas that are not indicated by spray density. These blank areas are the areas where the spray density was not measured during the water spray test, but of course it can be assumed that the entire spray is sprayed with water droplets, because the water droplets are diffused into the soil of the spray area, and part of the water droplets are sprayed along The soil surface flows in the area. Even if the spray density varies between the stick and the point, it can be assumed that by spraying # on the entire triangle OAB as described above, the water is sprayed approximately uniformly in the eighth area of the sprayed seedling field 1. By applying the diameters, fan angles, and elevation angles of the nozzles a to η and p to s set in the above process to the remaining seven-eighth ffi area of the spray area 1, it is similarly possible to determine Spray the nozzle diameter, fan angle and nozzle elevation angle to the entire spray area 1. Since the line segments OA and OB of the triangle OAB are the same as the adjacent triangles, and since it can be seen from FIG. 4 that the water droplets from the nozzles a and b can be sufficiently sprayed to the line segments OA and OB of the adjacent triangle , So it can be specified to spray water to the nozzles where the OA and OB overlap. Therefore, 120 (= 16x8 — 8) nozzles must be installed to spray approximately evenly (please read the note Ϋ on the back and then fill in this page) ό • Installation.

In addition, the comparative sprinkler head has a larger water sprinkle in the area near the sprinkler, and each unit The water spray of the face water drops with the increase of the distance from the water sprayer. Therefore, compare the spray head It is impossible to perform uniform water flow.

Description of the invention (43) The conditions, where; 9 is the elevation angle of the second imaginary 缭 9 b, must meet the condition of "< point. Therefore, the band surface is set in a fan garden, and the elevation angle of the second imaginary line to the center 0 is 0 ° to 85. (Preferably 15 ° to 8 5 °) 0 In the case of spraying water to different vegetables or flowers planted on the ridge, or spraying to trees that are planted unreasonably, by setting the ribbon-like surface 5 Satisfy the above conditions, you can save the water to the area where the water is not sprayed (such as the space between the trees of each line). Therefore, it is possible to reduce "Zhen" who sprinkled water. That is, it can reduce the waste of water. In addition, by setting 15 for banded seedlings. With an elevation angle of 85 °, the impact force of the water droplets sprayed on the soil surface of the sprayed ffi field becomes smaller. That is, water tsunami spraying can be performed so that the sprayed water droplets will not bounce off the soil surface, resulting in gentle spraying of water. In particular, for example, the elevation angle of the band zone must be selected for the size of the spray® field, the distance from the sprayer to the desired water spray field, and the% spray diameter. The nozzle 2 formed in the band-shaped surface 5 has a diameter, which increases as the distance from the vertex 3 increases. That is, the nozzle 2 can be formed so that its straight t I '.. diameter can be continuously increased as the distance from the apex 3 increases, or several adjacent nozzles 2 can have equal diameters. The pattern of the strip-shaped seedlings 5 on the sprinkler head 1 is shown in Figure 20, that is, the nozzle distribution circle, indicating that the desired open area is a rectangular shape (that is, a strip).

Since the strip-shaped seedling shape 5 is placed on each side of the first imaginary imaginary 8 past the top 3 of the sprinkler head 1, when the sprayed seedling area is divided into two surface areas, by setting vertically The sprayer is between the two spraying areas, and the spray head 1 can spray water to the two spraying areas at the same time. Since the strip-shaped zones 5 are each set in an elevation range of 15 ° to 8 5β, and the nozzle diameter is formed in a range of 0.4 mir to 0.8 μ, the sprayed water droplets act on the spray The impact force on the soil surface of the area becomes smaller, and gentle water spraying can be performed, and the water droplets sprayed will not bounce off the soil surface. That is, I am not afraid that the seeds sowed will run off the soil, or the roots will be caught outside the soil by spraying water and hinder the growth of plants. The following will describe the water spray body of each unit surface of the spray head 1 according to the embodiment of the fourth aspect of the present invention: The desired spray area is composed of two spray areas, each spraying class The fields have equal rectangular spray areas, and the sprinklers are arranged vertically at the desired position between the two spray surface areas on which water will spray.
