Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gardening, in particular to a lawn spraying device. Background Art
[0002] With the improvement of urban landscaping level, higher requirements are also put forward for the management and maintenance of grassland. As an indispensable part of the garden irrigation system, the performance and quality of the lawn sprinkler device directly affect the growth of the grassland and the overall effect of the garden landscape. The lawn sprinkler device is generally composed of a water inlet, a fixed base, a third support column, a sprinkler rod and a nozzle. First, the lawn sprinkler device is fixed on the lawn through the fixed base, and then the water source is connected to the water inlet. After the water is passed, the water will enter the interior of the fixed base. The interior of the fixed base contains a turbine. The water flow increases the pressure through the turbocharger structure and is injected into the sprinkler rod. When the water flows from the sprinkler rod into the nozzle, its speed and pressure will suddenly increase, thereby forming a high-speed water flow. When the water sprayed out from the nozzle contacts the air, it will automatically disperse into many small water droplets, thereby achieving uniform irrigation of the grassland.
[0003] Although it is possible to achieve uniform spraying on the lawn, the metal parts of the lawn sprinkler system are susceptible to corrosion on rainy days, especially under long-term acidic rain erosion. This is because the acidic substances in the rainwater (such as sulfuric acid, nitric acid, etc.) react chemically with the metal surface, causing the metal to gradually oxidize and corrode. This corrosion process not only affects the appearance of the device, but more importantly, it will cause key components inside the device (such as nozzles, pipes, etc.) to rust and clog.
[0004] For this purpose, we propose a lawn sprinkler device. Utility Model Content
[0005] The utility model provides a lawn spraying device.

[0015] The utility model is provided with a protective component, which can, on rainy days, enable the second rain shield and the rotating rod to move downward under the action of gravity until the second rain shield is attached to the first rain shield. During the movement, the grooves between the second rain shield and the first rain shield are misaligned, thereby achieving rain shielding for the nozzle and protecting the device, and avoiding the metal parts of the lawn sprinkler device from being easily corroded under the long-term erosion of acidic rainwater. This is because the acidic substances in the rainwater (such as sulfuric acid, nitric acid, etc.) react chemically with the metal surface, causing the metal to gradually oxidize and corrode. This corrosion process not only affects the appearance of the device, but more importantly, it will cause key components inside the device (such as nozzles, pipes, etc.) to rust and clog, thereby improving the service life of the lawn sprinkler device.

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Example 1
[0022] See also Figure 1-3 The figure shows a lawn sprinkler device, comprising a fixed base 2, a water inlet 1 provided on one side of the fixed base 2, a third support column 14 provided at the top of the fixed base 2, sprinkler rods 15 evenly provided on the side walls of the third support column 14, a sprinkler head 3 evenly provided at the top of each sprinkler rod 15, and a protective assembly provided at the top of the third support column 14;
[0023] The protection assembly includes a second support column 12 arranged at the top of the third support column 14, the outer wall of the second support column 12 is fixedly mounted with a first rain shield 5, the inner wall of the second support column 12 is movably mounted with a rotating rod 10, the top of the rotating rod 10 is provided with a second rain shield 6, the first rain shield 5 and the second rain shield 6 are both provided with a groove 13, and the second support column 12 and the rotating rod 10 are connected through a rotating assembly.
[0024] In this embodiment: through the provision of a protective component, the second rain shield 6 and the rotating rod 10 can be moved downward by gravity on rainy days until the second rain shield 6 is attached to the first rain shield 5. During the movement, the groove 13 opened between the second rain shield 6 and the first rain shield 5 is misaligned, thereby achieving rain shielding for the nozzle 3 and protecting the device, and avoiding the metal parts of the lawn sprinkler device from being easily corroded under long-term acidic rain erosion. This is because the acidic substances in the rainwater (such as sulfuric acid, nitric acid, etc.) react chemically with the metal surface, causing the metal to gradually oxidize and corrode. This corrosion process not only affects the appearance of the device, but more importantly, it will cause key components inside the device (such as the nozzle 3, pipes, etc.) to rust and clog, thereby improving the service life of the lawn sprinkler device.
[0025] See also Figure 2 and Figure 3In the figure, the rotating assembly includes a first support column 9 arranged on the inner wall of the second support column 12, a slide plate 16 is slidably installed on the inner wall of the second support column 12, a spring 4 is fixedly installed on the bottom end of the slide plate 16, and the spring 4 is placed below the rotating rod 10. The outer wall of the rotating rod 10 is provided with an arc groove 11, and the first support column 9 is embedded in the arc groove 11.
[0026] In this embodiment: by setting up a rotating assembly, the rotating rod 10 can be lowered on rainy days. During the lowering process, the first support column 9 and the arc groove 11 are embedded and matched to realize the rotational movement of the rotating rod 10. When the rain stops, the upward force of the spring 4 component causes the rotating rod 10 to rotate to the starting position through the rotating assembly, thereby driving the second rain shield 6 to move up and down while being able to rotate, thereby protecting the nozzle 3.
[0027] Working principle: On rainy days, the collection barrel 7 will collect rainwater. As the rainwater accumulates, the gravity of the collection barrel 7 will continue to increase. Finally, under the action of gravity, the second rain shield 6 will move downward and drive the rotating rod 10 to move together. The arc groove 11 on the outer wall of the rotating rod 10 will fit with the first support column 9. During the descent, a certain rotation movement will be generated. When it descends to the bottom, the first rain shield 5 and the second rain shield 6 will fit together and the groove 13 in the first rain shield 5 and the groove 13 in the second rain shield 6 will be staggered, thereby obtaining a rain shield effect for the nozzle 3 and the device. After the rain stops, the collection barrel 7 starts to drain water through the drain pipe 8 fixed at its bottom end. As the accumulated water is gradually discharged, the weight of the collection bucket 7 will continue to decrease, and the pressure received by the spring 4 will continue to decrease. When the weight of the collection bucket 7 is reduced to a certain extent, the spring 4 begins to rise and generates an upward force on the rotating rod 10 during the rising process. Similarly, in the process of the rotating rod 10 rising, the arc groove 11 provided cooperates with the first support column 9 to rotate again, and finally the second rain shield 6 is rotated to its original position and the grooves 13 in the first rain shield 5 and the second rain shield 6 are flush, so as not to affect the next spraying.
[0028] Example 2
[0029] See also Figure 1 This embodiment further illustrates Example 1. In the figure, a collecting bucket 7 is fixedly installed on the top of the second rain shield 6.
[0030] In this embodiment: on rainy days, the structure will receive rainwater and bring gravity to the second rain shield 6 and the rotating rod 10 below, so that the second rain shield 6 and the rotating rod 10 can move downward, thereby achieving the second rain shield 6 being attached to the first rain shield 5, avoiding the problem of the nozzle 3 and the device being washed by rainwater for a long time.
[0031] See also Figure 1 and Figure 3 As shown in the figure, a drain pipe 8 is fixedly installed on one side of the bottom end of the collecting barrel 7.
[0032] In this embodiment, when the rain stops, the drain pipe 8 can discharge the rainwater accumulated in the collection barrel 7, thereby reducing the gravity of the collection barrel 7, so that the lower spring 4 can reduce the pressure and rise upward to prevent the second rain shield 6 from blocking the spraying of the nozzle 3.
[0033] See also Figure 1 and Figure 3 In the figure, the cross-sectional diameter of the bottom end of the collecting barrel 7 is smaller than the minimum diameter from the cross-sectional center of the second rain shield 6 to the side wall of the groove 13.
[0034] In this embodiment, when the device is used, the position of the collecting barrel 7 is restricted, thereby avoiding the problem of blocking the groove 13 and affecting the normal spraying operation of the spraying device.
[0035] Example 3
[0036] See also Figure 1 and Figure 3 In the figure, the side of the drain pipe 8 away from the collection barrel 7 is set to be inclined downward.
[0037] In this embodiment, when the rain stops, the rainwater accumulated in the collecting barrel 7 can be discharged smoothly through the downwardly inclined structure of the drain pipe 8, thereby avoiding the problem of accumulated water that cannot be effectively discharged.
[0038] See also Figure 1 and Figure 3 In the figure, the groove 13 is placed directly above the nozzle 3, and the distance between the two sides of the groove 13 is greater than the distance between the two sides of the nozzle 3.
[0039] In this embodiment, when the lawn sprinkler is in use, each groove 13 is located directly above the sprinkler head 3 , so that the sprinkler will not be blocked during normal spraying.
