Description

Technical Field

[0001] The invention relates to a sprinkler nozzle, in particular to a multifunctional sprinkler nozzle with variable range and full-automatic adjustment of spraying uniformity. Background Art

[0002] Now and in the future, new water-saving irrigation technology for agricultural farmland and urban lawn greening will definitely replace the original flooding form. It is well known that farmland and green lawn are mostly square, rectangular, polygonal and other areas, but the spraying area of sprinkler nozzles used for nearly a hundred years is still circular, which can easily cause the problem of not being able to spray corners. If blind spots are avoided in the area, multiple sprinkler nozzles need to be installed, which will cause a considerable part of the area to be sprayed overlappingly, and water resources cannot be fully utilized, resulting in a new round of water resource waste. In response to this situation, China Patent Publication No. CN2346510Y (Application Date: 1998.7.22) discloses a A "sprinkler nozzle" is primarily composed of a nozzle housing and a guide plate. Curved baffles are machined around the upper edge of the nozzle housing. The guide plate has a diversion angle of 40 to 45 degrees. The curved nozzle outlet creates a square shape for the sprayed water. Separately, Chinese patent publication number CN2031200Y (application date: March 7, 1988) discloses a "sprinkler with a square spray coverage area." It primarily consists of a nozzle, a nozzle, and a water pressure regulator. The water pressure regulator is a closed-end circular tube with a water supply strip on its wall. Its width varies according to the required water volume, resulting in a square spray coverage area. However, due to structural deficiencies, although the above two solutions can change the spray shape so that the spraying areas do not overlap, they are both limited to a square spraying area and have relatively simple functions. For this reason, the applicant's prior applications for "variable range fully automatic water-saving sprinkler nozzles" with patent numbers 2003246167.4 and 200820069387.6 were both granted patents, and the use effect has been greatly improved and enhanced. However, with the increasing requirements and problems encountered in research and development, the previous products still have deficiencies in structure and efficacy, and the use effect is not completely satisfactory, especially in terms of spraying form, spraying uniformity, automatic control effect and adaptability, which need further improvement and innovation. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the existing technology, the purpose of the present invention is to provide a multifunctional variable-range sprinkler nozzle with fully automatic adjustment of spraying uniformity, which can effectively solve the problems of few sprinkler forms, uneven spraying, poor automatic control effect, and low effective utilization rate of existing field edges.

[0004] To achieve the above-mentioned purpose, the technical solution provided by the present invention is a multifunctional variable-range sprinkler nozzle with fully automatic adjustment of spraying uniformity, comprising a nozzle body, a rocker arm, a main nozzle and a sub-nozzle, wherein the main nozzle and the sub-nozzle are respectively provided on the water outlets on both sides of the nozzle body with an upwardly inclined main nozzle and a sub-nozzle, and the top view angle between the main nozzle and the sub-nozzle is 0° to 180°. The nozzle body is connected to the upper end hole of the water inlet joint and is installed on the water inlet joint. A first support plate and a second support plate are respectively provided on the outside of the middle of the nozzle body. The control panel is installed on the middle and lower part of the nozzle body through the lower spring, and the rocker arm is installed through the rocker arm shaft and the upper torsion spring. On the upper part of the nozzle body, the lower parts of both sides of the nozzle body are correspondingly provided with a downwardly inclined first adjusting link and a second adjusting link, one end of the first adjusting link and the second adjusting link are in sliding contact with the surface of the control panel, and the other ends pass through the first support plate and the second support plate respectively and are connected to the first adjusting rod and the second adjusting rod, one end of the first adjusting rod is connected to the lower end of the nozzle body, and the other end is connected to the adjusting mechanism at the nozzle outlet of the auxiliary nozzle via the first return spring, one end of the second adjusting rod is connected to the lower end of the nozzle body, and the other end is connected to the main nozzle via the second return spring, forming a range adjustment mechanism for the main nozzle and the auxiliary nozzle.

[0005] The present invention has a simple structure and a scientific and reasonable design. The spraying area can be of various shapes and can spray different area shapes to meet the requirements of various terrains. It avoids overlapping spraying of multiple nozzles and the problem of ineffective spraying caused by spraying water on the road, which causes waste of water resources.

[0015] The specific implementation of the present invention is described in detail below in conjunction with specific circumstances.

[0016] In conjunction with the accompanying drawings, a multifunctional variable range sprinkler nozzle with fully automatic adjustment of spraying uniformity is given, including a nozzle body, a rocker arm, a main nozzle and an auxiliary nozzle. The water outlets on both sides of the nozzle body 2 are respectively equipped with an upwardly inclined main nozzle 1 and an auxiliary nozzle 7, and the top view angle between the main nozzle 1 and the auxiliary nozzle 7 is 0° to 180°. The nozzle body 2 is connected to the upper end hole of the water inlet joint 15 and is installed on the water inlet joint 15. The first support plate 12a and the second support plate 12b are respectively installed on the outside of the middle of the nozzle body 2. The control disk 14 is mounted on the middle and lower part of the nozzle body 2 through the lower spring 13. The rocker arm 4 is mounted on the upper part of the nozzle body 2 through the rocker arm shaft 6b and the upper torsion spring 6. The two sides of the nozzle body 2 The lower part is correspondingly equipped with a downward-inclined first adjusting link 11a and a second adjusting link 11b, one end of the first adjusting link 11a and the second adjusting link 11b are in sliding contact with the surface of the control disk 14, and the other ends pass through the first support plate 12a and the second support plate 12b respectively and are connected to the first adjusting rod 10a and the second adjusting rod 10b. One end of the first adjusting rod 10a is connected to the lower end of the nozzle body 2, and the other end is connected to the adjustment mechanism at the nozzle outlet of the auxiliary nozzle 7 through the first return spring 9a. One end of the second adjusting rod 10b is connected to the lower end of the nozzle body 2, and the other end is connected to the main nozzle 1 through the second return spring 9b, constituting the range adjustment mechanism of the main nozzle 1 and the auxiliary nozzle 7.

[0017] In order to ensure better implementation effect, the main nozzle 1 and the auxiliary nozzle 7 are both circular tubes with closed front ends.

[0018] The first adjustment link 11a and the second adjustment link 11b are equipped with sliding heads or rollers at the ends that contact the control disk 14. The first adjustment link 11a and the second adjustment link 11b move up and down under the action of the convex and concave surfaces of the control disk 14 to adjust and control the water spray range and precipitation uniformity of the main nozzle 1 and the auxiliary nozzle 7.

[0019] The main nozzle 1 and the auxiliary nozzle 7 are mounted on the nozzle body 2 at an angle of 135 degrees, and the center line of the intersection of the main nozzle 1 and the nozzle body 2 and the center line of the intersection of the auxiliary nozzle 7 and the nozzle body 2 are on the same horizontal line (such as Figure 1 、 Figure 7 ) or staggered arrangement (such as Figure 8 ).

[0020] The front end of the rocker arm 4 is S-shaped or straight, and the end corresponding to the main nozzle 1 has an oblique side arm connected as a whole. The oblique side arm is composed of a first part 18, a second part 19 and a third part 20. The outer end of the first part 18 forms a cutting edge 17, the water cutting angle α is 1°-90°, the thickness H is 1-100mm, and the water flow is straight (such as Figure 4 ) or curved lines (such as Figure 3 ), the angle between the straight line of the water spray and the oblique side arm 18 is 1°-45°, and the length is 5-200mm. When the water flow from the main nozzle 1 hits the water-cutting groove at the oblique side arm 18 at the front end of the rocker arm 4, the rocker arm 4 swings counterclockwise instantly. Due to the action of the upper torsion spring 6, the rocker arm 4 violently hits the nozzle body 2, so as to achieve the purpose of shifting the nozzle body 2 as a whole in the clockwise direction. After the water-cutting groove at the front end of the rocker arm 4 cuts water and hits the nozzle body 2, there is a reaction force function, which makes the rocker arm 4 swing counterclockwise instantly. At this time, the upper torsion spring 6 allows the rocker arm 4 to continue to hit the nozzle body 2 clockwise in time, repeatedly prompting the nozzle body 2 to rotate in a circle step by step, so as to achieve intermittent, uniform and repeated spraying.

[0021] The main nozzle 1 is equipped with a flow stabilizer 3 and a limit screw 5. The second adjusting rod 10b is located in the front and lower part of the main nozzle 1. The adjusting mechanism at the front lower end of the nozzle of the auxiliary nozzle 7 includes a fixing part 8a and a water regulating tongue 8 that passes through the fixing part 8a. The lower part of the water regulating tongue 8 is connected to the first return spring 9a to achieve the purpose of limiting the water outlet diameter of the auxiliary nozzle 7.

[0022] The control disk 14 is a flat or inclined disk with staggered convex and concave surfaces on its upper surface. The control disk 14 is fixed together with the water inlet joint 15. When the lower end of the first adjusting link 11a is located on the convex surface of the control disk 14, the lower end of the second adjusting link 11b is located on the concave surface of the control disk 14. When the lower end of the first adjusting link 11a is located on the concave surface of the control disk 14, the lower end of the second adjusting link 11b is located on the convex surface of the control disk 14, thereby achieving the purpose of limiting the water outlet diameter of the main nozzle 1 and the auxiliary nozzle 7.

[0023] A vertical pipe 16 is installed below the water inlet joint 15, and a sealing ring 16-1 is installed at the contact point between the water inlet joint 15 and the vertical pipe 16.

[0024] The upper inner ring of the control disk 14 is provided with an oblique tooth-shaped limit tooth 21, and a tongue piece 22 is installed under the second support plate 12b above the limit tooth 21. The tongue piece 22 and the limit tooth 21 contact and limit the position again and again during the sprinkling process to prevent the main and auxiliary nozzles from spraying too much.

[0025] The present invention is specifically described in the following examples. Example 1

[0026] The present invention is used (such as Figure 1 ), point the concave position of the control disk 14 toward the place with the longest range (such as the corner of a square), connect the water source connector 15 at the lower end of the nozzle body to the tap water pipe, open the control valve to let the tap water enter the inner cavity of the nozzle body 2, and due to the effect of water pressure, the water flow from the main nozzle 1 rushes towards the water cut-off groove at the oblique side arm 20 at the front end of the rocker arm 4, causing the rocker arm 4 to hit the nozzle body 2 and then quickly leave in a counterclockwise direction (the direction of water flow is shown in the figure). Figure 3 、 Figure 4 ), due to the torsion force of the upper torsion spring 6, the rocker arm 4 repeatedly hits the nozzle body 2 - moves away - hits - moves away, causing the nozzle body 2 to rotate step by step. At this time, the first adjusting rod 10a, the second adjusting rod 10b, the first adjusting link 11a and the second adjusting link 11b rotate accordingly. Since the upper surface of the control disk 14 has a certain regular convex and concave shape, when the lower end of the first adjusting link 11a slides to the convex point, the second adjusting link 11b moves to the concave point, and the second adjusting rod 10b connected thereto blocks the water flow sprayed by the main nozzle 1. At this time, the range of the main nozzle 1 is shorter; on the contrary, when the second adjusting link 11b slides to the concave point, the second adjusting rod 10b gradually loses its effect on the water flow sprayed by the main nozzle 1, and the range of the main nozzle 1 changes from near to far. At the same time, the range of the auxiliary nozzle 7 changes from far to near until it is closed. In this way, the size and range of the water flow can be changed as needed, thereby achieving different spraying shapes.

[0027] The range control disk 14 can be designed with a flat or inclined surface. Experimental results show that when the convex and concave shapes on the control disk 14 are arranged in a radial pattern with four convex and four concave shapes with unequal spacing, the nozzle sprays in an irregular quadrilateral shape; when four convex and four concave shapes are arranged at equal spacing, the nozzle sprays in a square shape; when three convex and three concave shapes are arranged at equal spacing, the nozzle sprays in an equilateral triangle shape; when two convex and two concave shapes are arranged at equal spacing, the nozzle sprays in an elliptical shape; and when one convex and one concave shape are arranged at equal spacing, the nozzle sprays in a pointed shape with one end and a rounded end. Using different control disks 14 as needed can meet the needs of different terrains.

[0028] When spraying at a long distance, the second regulating rod 10b at the front end of the main nozzle 1 is gradually lowered to lose its effect on the water flow. At the same time, the water regulating tongue 8 at the lower end of the nozzle of the auxiliary nozzle 7 gradually closes the water outlet of the auxiliary nozzle 7 from low to high. At this time, the water pressure in the neck cavity of the nozzle body 2 increases instantly, forcing the range of the main nozzle 1 to change from near to far, and the range of the auxiliary nozzle 7 to also change from far to near. According to needs, the water regulating tongue 8 at the lower end of the water outlet of the auxiliary nozzle 7 can also be adjusted to close. Because the nozzle body 2 is continuously impacted by the rocker arm 4 and shifts and rotates step by step, at this time, under the action of the control disk 14, the second regulating rod 10b in front of the main nozzle 1 moves upward, blocking The water flow sprayed by the main nozzle 1 is blocked, and the range of the main nozzle 1 is also from far to near; the water regulating tongue 8 in front of the auxiliary nozzle 7 moves downward, and the range of the auxiliary nozzle 7 is also from near to far. The main nozzle 1 is responsible for spraying the farthest two-thirds of the distance in the entire area, avoiding overlapping spraying and ineffective spraying at too far, and the auxiliary nozzle 7 is responsible for spraying the closest one-third of the distance in the entire area, avoiding the dead angle of the nozzle at close range (commonly known as "darkness under the lamp"), so as to achieve the purpose of controllable geometric area, concentrated precipitation, and uniform spraying in the area, without wasting water, and achieving the purpose of saving water, concentrated precipitation, reducing sprinkler time, and improving sprinkler efficiency. Example 2

[0029] The structure and use of the present invention are basically the same as those of Example 1, except that Figure 7 The structure on the nozzle body 1 is simpler, and the rocker arm 4 is directly installed on the main nozzle, which increases the neck cavity length of the main nozzle 1 and makes the nozzle range longer. Due to the longer range of the main nozzle 1, the dead angle of the precipitation area of nearly one-third of the range will be correspondingly expanded, so the role of the auxiliary nozzle 7 is more obvious. When the rocker arm 4 hits the nozzle body 2 with too much force, the tongue 22 and the limit tooth 21 prevent the span from being too large and control it within 1° / S, making the spraying span more reasonable and uniform.

[0030] Moreover, in this embodiment, the overhead angle between the main nozzle 1 and the auxiliary nozzle 7 is 180°, and the swing arm 4 is a straight-line structure, which is mainly used in places where space is limited in the spraying area or where spraying cannot be done upwards. The above does not mean that the swing arm 4 in this embodiment must be a straight-line structure, it can also be S-shaped, and the overhead angle between the main nozzle 1 and the auxiliary nozzle 7 can also be any angle of 0-180°. Example 3

[0031] The structure and use of the present invention are basically the same as those of Example 1, except that Figure 6When in use, the present invention is combined with a multi-stage telescopic mechanism (a known commercially available product). The present invention is installed in the multi-stage telescopic mechanism. When the valve is opened and water flows into the multi-stage telescopic mechanism housing 26, the locking end 27, the multi-stage telescopic tube 28, and the water source connector 15, the water pressure in the pipe network causes the multi-stage telescopic tube 28 to extend upward from the ground by more than 20 cm (depending on actual needs). When the valve is closed, the compression spring 29 forces the multi-stage telescopic mechanism to be concealed in the pre-set first-stage telescopic, second-stage telescopic, etc., dense clusters of seedlings or flowers. At this time, the top cover 31 is flush with the ground, preventing damage or loss caused by the exposed nozzle, which affects the overall aesthetics. Example 4

[0032] The structure and use of the present invention are basically the same as those of Example 2, except that Figure 8 , Figure 8 The main nozzle 1 and the auxiliary nozzle 7 are one on the top and one on the bottom, the swing arm 4 is a straight-line structure, and the rocker arm shaft 6b is installed above the main nozzle 1. Other structures and usage are the same as those in Example 2 and will not be described in detail. For this embodiment, the swing arm 4 can also be S-shaped.

[0033] The present invention has a simple structure and a scientific and reasonable design. Compared with the prior art, it has the following advantages: 1. The spraying area can be of various shapes. Nowadays, park lawns and urban living areas, gardens, and green spaces are all decorative and landscaped, and most of them are square, circular, rectangular, elliptical, triangular, or a combination thereof. Ordinary sprinklers can only spray circular or fan-shaped shapes when the pressure and caliber are certain, which is no longer suitable for the sprinkler irrigation requirements of field agriculture and landscaping art shapes. The present invention adopts different control disks to spray different area shapes, which can meet the requirements of various terrains, avoid overlapping spraying of multiple sprinklers, and avoid ineffective spraying caused by spraying water onto the road, resulting in waste of water resources; 2. The overall engineering investment for the sprinkler irrigation system of this invention can be reduced by more than half compared to traditional sprinkler irrigation technology. The control plate is an injection-molded component with a regular convex and concave shape. The main nozzle adjustment plate and auxiliary nozzle adjustment lever move up and down to adjust the water outlet diameter, thereby varying the spray range and conserving water. This allows for adaptive and uniform water output, shortens spraying time, and improves work efficiency. These components are simple in shape and easy to process. All components in the same series and multiple varieties are universal; only the corresponding control plate needs to be replaced. This makes it suitable for large-scale assembly line production, thereby reducing the cost of the sprinkler nozzles. 3. The present invention sprays more evenly. A flow stabilizer is installed in the nozzle to make the water flow farther and more even, achieving better sprinkler irrigation effect. 4. The invention has a wide range of applications and can be used in agricultural fields, landscaping, vegetable oil tea, flower nurseries, new forage grass, material field dust reduction and other industries. Under the same level of water pressure and the same type of nozzle, it has a longer range and higher precipitation uniformity than traditional nozzles; 5. The present invention has good water-saving effect and high spraying efficiency. The present invention changes the coverage shape of the spraying area, which can ensure that the spraying is in place and the spraying area does not overlap, saving a lot of water. If a large area is sprayed, the use of sprinklers and underground pipes can be reduced by three-fifths compared with traditional sprinklers. It is widely used in various sprinkler irrigation occasions, increasing the utilization rate of reclaimed water in cities, reducing investment plans for domestic water supply facilities, and improving groundwater recovery; rural land transfer, water-saving intelligent irrigation agriculture, ensuring food security, biofuel raw material base construction, and grass-replacing-wood industry have long-term social and economic significance after promotion.

[0034] It should be pointed out that the above is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any technician familiar with this profession can make changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present invention, and all of them fall within the scope of protection of the present invention.
