Description

Technical Field

[0001] The utility model belongs to the technical field of seedling raising spraying, and particularly relates to a multi-head spray rod and sleeve assembly. Background Art

[0002] Circulating motion seedling beds are mostly used for batch cultivation of seedlings. The circulating movement and innovative design methods adopted can automatically turn the carriers loaded with seedling trays, spray moisture, and control and adjust the environmental temperature, humidity and light, giving full play to the role of three-dimensional space, saving a lot of farmland resources, and there is no need to reserve seedling fields for early rice, realizing a factory-based seedling cultivation model.

[0003] Multiple adjustable spray heads are installed at equal distances on a water pipe, with water inlet at one end and a plug at the other end to form a straight-rod spray device, which realizes automatic spraying of the seedling tray. Since the two ends of the seedling tray of the circulating motion seedling cultivation are easily dried by the wind, the spraying amount of the existing spray rod is the same at each end, resulting in the easy evaporation of water or chemicals sprayed on the two ends of the seedling tray. Since the seedlings absorb water or other nutrients slowly, the growth rate of the seedlings at the two ends is lower than that of the seedlings in the middle. In the existing pipeline transportation, since the transportation pipeline is a hose made of PVC or other materials, when the transportation pipeline is too long, the middle part sinks due to the liquid inside, which affects the overall aesthetics. At the same time, the sinking onto the seedlings will crush the seedlings and affect their growth. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0025] The following combination Figure 1-6The specific embodiment of the utility model is described, a multi-head spray rod and sleeve assembly includes a delivery main pipe 1, a delivery cavity 11 is formed inside the delivery main pipe 1, a plurality of delivery branch pipes 12 are provided on the delivery main pipe 1, and a plurality of spray heads 2 correspond to different seedlings in each area on the seedling tray, so as to realize zone spraying of different seedlings and make each seedling sprayed uniformly to ensure the synchronous growth of the seedlings. The plurality of delivery branch pipes 12 are equidistantly distributed along the length direction of the delivery main pipe 1, and the delivery branch pipes 12 at both ends of the delivery main pipe 1 are connected with spray joints 13. At least two spray heads 2 are connected to the mist joint 13, and one of the spray heads 2 is installed on the delivery branch pipe 12 between the two spray joints 13. In this embodiment, two spray heads 2 are installed and connected to the spray joint 13. By installing spray joints 13 at both ends of the delivery main pipe 1 and connecting multiple spray heads 2 to the spray joint 13, the amount of water sprayed on both ends of the delivery main pipe 1 can be increased to avoid the seedling tray from evaporating easily due to the two ends being close to the outside air, so that the water sprayed at both ends of the delivery main pipe 1 is consistent with the water content in other areas after removing the evaporated water.

[0026] Please refer to Figure 1-2 As shown, the delivery branch pipe 12 is connected to the delivery cavity 11, and an internal mounting thread 21 is formed inside the spray head 2. The spray head 2 between the two spray joints 13 is threadedly connected to the delivery branch pipe 12 through the internal mounting thread 21 formed therein. In the spray heads 2 at both ends of the delivery main pipe 1, each spray head 2 is threadedly connected to the delivery branch pipe 12 through the internal mounting thread 21 formed therein, thereby realizing mutual communication between each spray head 2 and the delivery cavity 11, so that the moisture in the delivery main pipe 1 is sprayed onto the seedlings in each area of ​​the seedling tray through each spray head 2.

[0027] Please refer to Figure 3-6 As shown, an inner concave ring 121 is formed on the circumferential surface of the delivery branch pipe 12 on which the spray joint 13 is installed, and a limiting tooth 122 is provided in the inner concave ring 121. The limiting tooth 122 is fixedly connected to the delivery branch pipe 12, and the limiting groove 133 is recessed into the interior of the spray joint 13 to provide space for mutual limitation between the delivery branch pipe 12 and the spray joint 13.

[0028] Please refer to Figure 3-6As shown, an inner convex ring 132 is formed on the top of the spray joint 13, and the inner convex ring 132 is adapted to the inner concave ring 121. A limiting groove 133 adapted to the limiting tooth 122 is provided on the inner convex ring 132. The cooperation of the limiting tooth 122 and the limiting groove 133 is used for the rotation adjustment of the spray joint 13 on the delivery branch pipe 12. The spray joint 13 and the delivery branch pipe 12 can realize mutual rotation adjustment, wherein the mutual adaptation between the inner convex ring 132 and the inner concave ring 121 realizes the mutual rotation between the delivery branch pipe 12 and the spray joint 13. Mutual limitation and support are used to prevent the spray connector 13 from slipping on the delivery branch pipe 12; the limiting tooth 122 and the limiting groove 133 are adapted to each other. When the spray connector 13 rotates on the delivery branch pipe 12, the limiting tooth 122 will be slightly deformed. When it rotates into the limiting groove 133 adapted thereto, the deformation is reset and the two are mutually limited in the limiting groove 133. The mutual cooperation between the limiting groove 133 and the limiting tooth 122 can limit the position of the spray connector 13 after rotation adjustment to prevent the spray connector 13 from rotating back and forth on the delivery branch pipe 12.

[0029] Please refer to Figure 2 As shown, the lower end of the spray joint 13 is formed with an external mounting thread 131, and the multiple spray heads 2 connected to the spray joint 13 are threadedly engaged with the external mounting thread 131 through the internal mounting thread 21 formed therein, and are respectively communicated with the delivery cavity 11 through the spray joint 13. The spray head 2 on the spray joint 13 is threadedly engaged with the external mounting thread 131 on the spray joint 13 through the internal mounting thread 21 formed therein, thereby realizing the installation of the spray head 2 on the spray joint 13 and making it communicate with the delivery cavity 11. It should be noted that the rotational connection between the delivery branch pipe 12 and the spray joint 13 can add a water pipe or a seal therein to prevent moisture leakage in the joint seam. These are all existing conventional technologies and will not be described in detail here.

[0030] Please refer to Figure 1 As shown, the spray head 2 installed on the spray joint 13 is flush with the bottom of the spray head 2 threadedly connected to the delivery branch pipe 12 to ensure that the distance between each spray head 2 and the seedling is equal, thereby reducing the growth difference between different seedlings.

[0031] Please refer to Figure 4As shown, a plug mounting thread 14 is formed at one end of the delivery main pipe 1, and the plug 3 is threadedly connected to one end of the delivery branch pipe 12 through the plug mounting thread 14. The plug 3 has an internal thread, and the plug 3 is threadedly engaged with the plug mounting thread 14 at one end of the delivery main pipe 1 through its internal internal thread to achieve blocking of the plug 3 on the delivery main pipe 1. The plug 3 and the delivery main pipe 1 are detachable and can be disassembled when necessary to extend the overall length of the delivery main pipe 1 to adapt to the requirements of seedling trays of different lengths.

[0032] Please refer to Figure 1 As shown, the other end of the delivery main pipe 1 is provided with a water source connector 4, one end of the water source connector 4 is connected to the delivery cavity 11, and the other end is connected to the water reservoir through a water pump. The water pump is used to increase the pressure in the delivery cavity 11 to meet the pressure requirements of each spray head 2, so that multiple spray heads 2 are used to spray seedlings in different areas. It should be noted that the pressure increase of the water pump or the boosting equipment must reach the pressure required by each spray head 2 to ensure that the spraying amount between each spray head 2 is consistent.

[0033] Please refer to Figure 2 As shown, the sleeve assembly includes a multi-head spray rod and a sleeve 5, the sleeve 5 is a metal sleeve 5, the sleeve sleeve 5 is connected to the delivery main pipe 1, and the sleeve 5 is provided with a sleeve interface 51 for the delivery branch pipe 12 to pass through. Since the delivery main pipe 1 is lined with a PE pipe, it will cause the middle part to sink during long-distance arrangement and transportation. By sleeve-fitting the sleeve 5 on the outside of the delivery main pipe 1, the sleeve 5 can be any metal sleeve, which can prevent the delivery main pipe 1 from sinking, thereby improving the overall aesthetics and use effect.

[0034] Working principle of this utility model:

[0035] One end of the delivery main pipe 1 is connected to the water pump and the water reservoir through the water source connector 4 to deliver water or nutrients to the delivery cavity 11. The water pump fills the delivery cavity 11 with pressure to form a high pressure inside the delivery cavity 11, so that the water in the delivery cavity 11 is sprayed onto the seedlings through the spray head 2. The other end of the delivery main pipe 1 is blocked with a plug 3. If necessary, an external pipe can be used to increase the length of the delivery main pipe 1.

[0036] According to the spraying requirements at both ends of the seedling tray, the spray joint 13 is rotated to change its angle on the conveying chamber 11, so that the positions of the spray heads 2 on the spray joint 13 and the spray heads 2 between the spray joints 13 form a single row or multiple rows to meet the spraying requirements of the seedlings;

[0037] In the rotation adjustment of the spray joint 13 and the delivery branch pipe 12, the inner convex ring 132 and the inner concave ring 121 limit their rotation to prevent the spray joint 13 from falling on the delivery branch pipe 12. At the same time, the limiting groove 133 cooperates with the limiting tooth 122. The limiting tooth 122 can slightly deform in contact with the limiting groove 133 during the synchronous rotation with the spray joint 13. When rotated into the limiting groove 133, the mutual limitation with the limiting groove 133 and the mutual locking between the spray joint 13 and the delivery branch pipe 12 prevent the spray joint 13 from rotating back and forth after adjustment.

[0038] After the spray joint 13 is adjusted, the water supply valve is opened and the water source is sprayed onto the seedlings on the seedling tray through each spray head 2. By arranging the spray joints 13 at both ends of the main conveying pipe 1 and installing multiple spray heads 2 through the spray joints 13, the water supply at both ends of the main conveying pipe 1 is increased to avoid insufficient absorption of water or nutrients by the seedlings due to drying caused by wind and cold, and ultimately achieve consistent growth rate of the seedlings in the same seedling tray.

[0039] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0040] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the scope of protection of the present utility model.
