Abstract
Description
Technical Field
[0001] This utility model relates to the field of drip irrigation equipment technology, and in particular to a nano-selenium slow-release drip irrigation device for tea roots. Background Technology
[0002] The key to producing selenium-enriched tea lies in using agricultural techniques to enable tea trees to effectively absorb and accumulate selenium. During cultivation, we discovered that drip irrigation technology can directly deliver water and nutrients to the root zone of crops, offering advantages such as high efficiency and water conservation. Theoretically, selenium supplementation can be achieved precisely and efficiently through a drip irrigation system. However, in the cultivation of selenium-enriched tea, selenium fertilizer is usually supplied to tea trees by directly mixing it into the drip irrigation mother liquor. Nano-selenium tends to aggregate and precipitate in the mother liquor, resulting in uneven distribution during long-distance delivery through the drip irrigation pipeline. Tea trees near water sources may receive excessively high concentrations of selenium, posing a risk of root toxicity; while tea trees further away may not accumulate selenium effectively due to insufficient concentration. Utility Model Content
[0003] The purpose of this utility model is to provide a nano-selenium slow-release drip irrigation device for tea roots, which enables the selenium fertilizer to be evenly delivered to the tea root area when the drip irrigation pipeline is used for long-distance transportation.
[0004] This utility model provides a nano-selenium slow-release drip irrigation device for tea roots, including a drip irrigation pipe with multiple connectors on the drip irrigation pipe, and the connectors are detachably connected to nano-selenium slow-release components; The nano-selenium slow-release component includes a slow-release cylinder connected to the connector, a base connected to the bottom of the slow-release cylinder, and a dropper provided at the bottom of the base; A bracket is fixed in the base, and a fixed shaft extending into the interior of the slow-release cylinder is fixed on the bracket; The slow-release cylinder contains a nano-selenium slow-release block, which is sleeved on the fixed shaft.
[0005] Preferably, the drip head includes a vertical tube communicating with the base, a horizontal tube communicating with the side wall of the vertical tube, and an outlet is provided on the wall of the horizontal tube. The horizontal tube is internally threaded with a screw rod. One end of the screw rod is provided with a sealing plug located inside the horizontal tube. The sealing plug corresponds to the position of the liquid outlet. The other end of the screw rod extends to the outside of the horizontal tube and is provided with a knob.
[0006] Preferably, the bottom end of the vertical tube is provided with a tapered plug.
[0007] Preferably, the top of the slow-release cylinder is connected to a water inlet elbow, which is threadedly connected to the connector.
[0008] Preferably, the outlet end of the water inlet elbow is equipped with a vertical rod, and the bottom end of the vertical rod is connected to a guide plate through a bearing. The water flow impacts the guide plate, causing it to rotate around the vertical rod.
[0009] Preferably, the guide vane is a plurality of pieces, and its shape is a spiral fan blade.
[0010] Preferably, the slow-release cartridge is connected to the base by a threaded connection.
[0011] Preferably, the cross-section of the fixed shaft is polygonal.
[0012] The tea root nano-selenium slow-release drip irrigation device provided by this utility model has the following beneficial effects: By independently setting nano-selenium slow-release components at each drip irrigation point, nano-selenium is distributed and uniformly supplied at the source, which completely solves the problem of uneven concentration caused by nano-selenium precipitation in the traditional mother liquor delivery method, making the selenium concentration at each drip irrigation point relatively consistent and preventing local concentrations from being too high or too low. The design of the rotatable guide plate creates a vortex in the water flow inside the slow-release cylinder, which not only enhances the contact efficiency between the water flow and the nano-selenium slow-release block, but also prevents the excessive dissolution of nano-selenium in local areas.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] In this embodiment, as Figure 1 and Figure 2As shown, a nano-selenium slow-release drip irrigation device for tea roots includes a drip irrigation pipe 1, with multiple connectors 2 on the drip irrigation pipe 1. Each connector 2 is detachably connected to a nano-selenium slow-release component 3. The nano-selenium slow-release component 3 includes a slow-release cylinder 31 communicating with the connectors 2. The bottom of the slow-release cylinder 31 is connected to a base 32, and a drip head 4 is provided at the bottom of the base 32. A bracket 331 is fixed in the base 32, and a fixed shaft 33 extending into the slow-release cylinder 31 is fixed on the bracket 331. A nano-selenium slow-release block 5 is provided inside the slow-release cylinder 31, and the nano-selenium slow-release block 5 is sleeved on the fixed shaft 33.
[0020] Thus, the water in the drip irrigation pipe 1 flows through the connector 2 into the slow release cylinder 31, and after contacting the nano selenium slow release block 5, it slowly dissolves and carries the nano selenium downwards, and is precisely dripped into the tea tree root area through the drip head 4, so that the selenium element can be continuously and evenly released. Specifically, unused connector 2 can be sealed with a matching threaded cap, the slow-release cylinder 31 has an internal cavity, and the base 32 and the slow-release cylinder 31 can also be fixed by other connection structures; the nano selenium slow-release block 5 is a porous solid block made by mixing and pressing nano zero-valent selenium, binder and slow-release material, using polyvinyl alcohol (POV) or hydroxypropyl methylcellulose (HPMC) as binder, and the nano selenium slow-release block 5 is manufactured by tablet molding process.
[0021] In some embodiments, such as Figure 5 As shown, the drip head 4 includes a vertical tube 41 connected to the base 32, a horizontal tube 42 connected to the side wall of the vertical tube 41, and an outlet 43 opened on the wall of the horizontal tube 42; a screw 44 is internally threaded to the horizontal tube 42, and a sealing plug 45 is provided at one end of the screw 44 inside the horizontal tube 42, the sealing plug 45 is positioned corresponding to the outlet 43, and the other end of the screw 44 extends to the outside of the horizontal tube 42 and is provided with a knob 46.
[0022] Specifically, by rotating the knob 46, the screw 44 and the sealing plug 45 can be moved axially along the horizontal tube 42, thereby adjusting the blocking area of the sealing plug 45 on the liquid outlet 43 and controlling the water output to adapt to the water requirements of tea trees at different growth stages. Specifically, the vertical tube 41 and the horizontal tube 42 are designed vertically, and the sealing plug 45 can be made of rubber material.
[0023] In some embodiments, such as Figure 5 As shown, a tapered plug 47 is provided at the bottom end of the vertical tube 41; Specifically, the conical plug 47 facilitates the stable insertion of the drip head 4 into the soil, so that the outlet 43 is located near the tea tree roots, thereby improving the utilization efficiency of water and selenium. In other embodiments, the tapered plug 47 may also be replaced with other forms of fixing structures, such as anchor plates or flared bases, to adapt to different soil conditions.
[0024] In some embodiments, such as Figure 1 As shown, the top of the slow-release cylinder 31 is connected to a water inlet elbow 34, which is threadedly connected to the connector 2. Specifically, the water inlet elbow 34 is easy to connect or disconnect from the connector 2 on the drip irrigation pipe 1, and the angle of the water inlet elbow 34 can be adjusted according to actual usage requirements.
[0025] In some embodiments, such as Figure 3 As shown, the outlet end of the water inlet elbow 34 is equipped with a vertical rod 6, and the bottom end of the vertical rod 6 is connected to a guide plate 62 through a bearing 61. The water flow impacts the guide plate 62, causing it to rotate around the vertical rod 6. Specifically, after the water flows out from the inlet bend 34, it impacts the guide plate 62, causing it to rotate and disperse the water flow, forming a vortex, which enhances the contact area between the water flow and the nano-selenium slow-release block 5. The top of the vertical rod 6 extends into the cavity of the water inlet elbow 34.
[0026] In some embodiments, such as Figure 3 As shown, the deflector 62 consists of multiple pieces, and its shape is a spiral fan blade.
[0027] Specifically, the spiral fan-shaped structure can guide the water flow to form a rotating flow field, improve the mixing effect, and prevent the surface of the nano-selenium slow-release block 5 from dissolving too quickly.
[0028] In some embodiments, such as Figure 2 As shown, the slow-release cartridge 31 and the base 32 are connected by threads; Specifically, the threaded connection structure facilitates the disassembly and replacement of the nano-selenium slow-release block 5, while the PTFE tape wrapped around the threads of the base 32 improves the sealing of the connection and prevents water leakage.
[0029] In some embodiments, such as Figure 3 and Figure 4 As shown, the cross-section of the fixed axis 33 is a polygon; It should be noted that the polygonal cross-section design of the fixed shaft 33 can prevent the nano-selenium slow-release block 5 from rotating on the fixed shaft 33, thus preventing local wear or uneven release caused by rotation.
[0030] The working principle of this application is illustrated below with a preferred embodiment: The drip irrigation pipe 1 and the slow-release cylinder 31 are connected by connecting the water inlet elbow 34 to the connector 2. When in use, the conical plug 47 is inserted into the root of the tea tree. External water enters the inlet elbow 34 through the drip irrigation pipe 1. The water flow impacts the guide plate 62 at the outlet end of the inlet elbow 34. The guide plate 62 rotates at the bottom end of the vertical rod 6 through the bearing 61, thereby changing the impact direction of the water flow and generating a vortex. The water flows downward along the outer wall of the nano-selenium slow-release block 5, carrying away the dissolved nano-selenium and collecting it in the vertical pipe 41, and flowing towards the horizontal pipe 42. The water seeps out through the liquid outlet 43. According to irrigation needs, the screw 44 is driven to rotate in the horizontal pipe 42 by the knob 46. The screw 44 drives the sealing plug 45 to move. By changing the blocking area of the sealing plug 45 on the liquid outlet 43, the water output of the liquid outlet 43 is controlled. After the nano-selenium slow-release block 5 in the slow-release cartridge 31 is completely dissolved, rotate the base 32 to separate it from the slow-release cartridge 31, install the new nano-selenium slow-release block 5 on the fixed shaft 33, and reconnect the base 32 and the slow-release cartridge 31 for use.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
