Description

Technical Field

[0001] This utility model relates to the technical field of tea tree planting and fertilization equipment, specifically a precision drip irrigation nozzle for tea garden fertilization. Background Technology

[0002] Fertilization in tea gardens is a key step in ensuring tea yield and quality, and drip irrigation technology is widely used in tea garden management because it can achieve precise water and fertilizer delivery and reduce resource waste.

[0003] First, tea trees vary significantly in height at different growth stages, and their growth status also differs in different areas of the tea garden. However, traditional drip irrigation nozzles are mostly set at a fixed height, unable to be flexibly adjusted according to the growth height of the tea trees. This results in fertilizer solution potentially being sprayed onto the leaves rather than near the roots, reducing fertilization efficiency. Second, different tea varieties and different growth stages of the same tea tree have significantly different fertilizer requirements, while existing nozzles have limited flow rate adjustment capabilities, often controlling the overall flow rate through a single valve. Furthermore, tea garden terrain often features varying slopes, and tea trees are distributed in rows, making the fixed or unstable spray angles of traditional nozzles problematic.

[0004] In view of this, we propose a precision drip irrigation nozzle for tea garden fertilization. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a precision drip irrigation nozzle for fertilizing tea gardens.

[0006] The technical solution of this utility model is:

[0007] A precision drip irrigation nozzle for tea garden fertilization includes an L-shaped mounting frame. An upper connecting pipe is mounted on the top of the L-shaped mounting frame, and a lifting corrugated pipe is mounted below the upper connecting pipe. Each end of the lifting corrugated pipe has an end block fixed at both ends. The upper end block is fixed to the upper connecting pipe, and the lower end block has a lower connecting pipe at its bottom. A drive mechanism for moving the lower end block up and down is mounted on the outside of the L-shaped mounting frame. A vertical pipe is provided on the outside of the lower connecting pipe. Several horizontal pipes of different diameters are installed between the lower connecting pipe and the vertical pipe. Each horizontal pipe is equipped with a manual valve matching its diameter. An angle-adjustable spray nozzle is mounted at the bottom of the vertical pipe via a rotating corrugated pipe. The adjustable corrugated pipe allows for nozzle height adjustment and, in conjunction with the drive mechanism, can adapt to tea trees of different growth heights. The combination of the lower connecting pipe, vertical pipe, and horizontal pipes of different diameters allows for manual valve control of fertilizer solution delivery at different flow rates, meeting the fertilization needs of different tea trees or regions. The rotating corrugated pipe and angle-adjustable nozzles allow for flexible adjustment of the spraying direction, ensuring precise drip irrigation of fertilizer to the required locations in the tea garden. The overall structure achieves both precision and flexibility in fertilization.

[0008] As a preferred technical solution, a flange is welded to the top of the upper connecting pipe. The flange connection enhances the sealing and robustness of the connection, while also facilitating installation and disassembly.

[0009] As a preferred technical solution, the driving mechanism includes a movable plate that is slidably connected to a vertical groove on an L-shaped mounting bracket. The movable plate is fixedly connected to an end block located at the lower part. A side plate is fixed to the right outer wall of the L-shaped mounting bracket near the top. A lead screw, threadedly connected to the movable plate, is rotatably mounted on the side plate. Rotating the lead screw can drive the movable plate to move up and down, thereby driving the extension and retraction of the lifting corrugated pipe to adjust the nozzle height.

[0010] As a preferred technical solution, an adjustment knob is coaxially welded to the top of the lead screw. The outer circumference of the adjustment knob is provided with anti-slip texture, and the adjustment knob is located above the side plate. This allows the operator to easily rotate the lead screw, making the nozzle height adjustment operation more labor-saving and convenient.

[0011] As a preferred technical solution, the movable plate includes an arc-shaped plate fixed to the end block and a drive block threadedly connected to a lead screw. A connecting block is provided between the arc-shaped plate and the drive block, and the connecting block is slidably connected to a vertical slide groove. The arc-shaped plate being fixed to the end block better adapts to the shape of the end block, enhancing the stability of the connection; the drive block being threadedly connected to the lead screw enables power transmission; and the connecting block sliding along the vertical slide groove provides guidance for the movement of the movable plate. The cooperation of these three components makes the movable plate move more smoothly during vertical movement, preventing deviation and ensuring the accuracy of nozzle height adjustment.

[0012] As a preferred technical solution, a hinge seat is fixed near the bottom of the outer circumference of the vertical pipe, and the nozzle is hinged to the inner wall of the hinge seat via a connecting shaft integrally formed on its outer wall. This allows the nozzle to rotate around the connecting shaft, enabling flexible adjustment of the spray angle.

[0013] As a preferred technical solution, a chuck coaxially fixed to the connecting shaft is rotatably mounted on one side of the outer wall of the hinge seat. Several slots are formed on the outer circumference of the chuck. These slots, in conjunction with positioning components, fix the angle of the spray nozzle. Once the spray nozzle is adjusted to a suitable angle, the slots quickly lock the current angle, preventing angular displacement due to external forces during spraying and ensuring the stability of the spray direction.

[0014] As a preferred technical solution, a fixing block is fixed to the outer wall of the hinge seat above the chuck. A positioning bolt is threaded onto the fixing block. When the positioning bolt is tightened on the fixing block, its bottom engages with the slot of the chuck. When the positioning bolt is tightened on the fixing block, its bottom engages with the slot of the chuck, which can firmly lock the position of the chuck and thus fix the spray angle of the nozzle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the lifting corrugated pipe allows for adjustment of the nozzle height, and in conjunction with the drive mechanism, it can adapt to tea trees of different growth heights. The combination of the lower connecting pipe, vertical pipe, and horizontal pipes of different diameters allows for the delivery of fertilizer solution at different flow rates via manual valves, meeting the fertilization needs of different tea trees or regions. The rotating corrugated pipe and the angle-adjustable spray nozzle can flexibly adjust the spraying direction, ensuring that the fertilizer is accurately dripped to the required location in the tea garden. The overall structure achieves both precision and flexibility in fertilization. Attached Figure Description

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A precision drip irrigation nozzle for tea garden fertilization includes an L-shaped mounting frame 1. An upper connecting pipe 2 is mounted on the top of the L-shaped mounting frame 1, and a lifting corrugated pipe 3 is mounted below the upper connecting pipe 2. An end block 30 is fixed at both ends of the lifting corrugated pipe 3. The upper end block 30 is fixed to the upper connecting pipe 2, and the lower end block 30 has a lower connecting pipe 4 at its bottom. A drive mechanism for driving the lower end block 30 to move up and down is mounted on the outside of the L-shaped mounting frame 1. A vertical pipe 6 is provided on the outside of the lower connecting pipe 4. Several horizontal pipes 5 of different diameters are installed between the lower connecting pipe 4 and the vertical pipe 6. Each horizontal pipe 5 is equipped with a manual valve 50 that matches its diameter. An angle-adjustable spray pipe 8 is mounted at the bottom of the vertical pipe 6 through a rotating corrugated pipe 9. The lifting corrugated pipe 3 allows for adjustment of the nozzle height, and in conjunction with the drive mechanism, it can adapt to tea trees of different growth heights. The combination of the lower connecting pipe 4, the vertical pipe 6, and the horizontal pipes 5 of different diameters allows for control of the delivery of fertilizer solution at different flow rates via the manual valve 50, meeting the fertilization needs of different tea trees or regions. The rotating corrugated pipe 9 and the angle-adjustable spray pipe 8 can flexibly adjust the spraying direction, ensuring that the fertilizer is accurately dripped to the required location in the tea garden. The overall structure achieves both precision and flexibility in fertilization.

[0027] As a preferred embodiment, a flange 20 is welded to the top of the upper connecting pipe 2. The flange connection enhances the sealing and firmness of the connection, and also facilitates installation and disassembly.

[0028] In a preferred embodiment, the driving mechanism includes a movable plate 12 that is slidably connected to the vertical slide groove 10 on the L-shaped mounting bracket 1. The movable plate 12 is fixedly connected to the end block 30 located at the lower part. A side plate 11 is fixedly located on the right outer wall of the L-shaped mounting bracket 1 near the top. A screw 13, which is threadedly connected to the movable plate 12, is rotatably mounted on the side plate 11. Rotating the screw 13 can drive the movable plate 12 to move up and down, thereby driving the lifting bellows 3 to extend and retract to adjust the nozzle height.

[0029] In a preferred embodiment, an adjustment knob 14 is coaxially welded to the top of the lead screw 13. The outer circumference of the adjustment knob 14 is provided with anti-slip texture, and the adjustment knob 14 is located above the side plate 11. This allows the operator to easily rotate the lead screw 13, making the nozzle height adjustment operation more labor-saving and convenient.

[0030] In a preferred embodiment, the movable plate 12 includes an arc-shaped plate 122 fixed to the end block 30 and a drive block 120 threadedly connected to the lead screw 13. A connecting block 121 is provided between the arc-shaped plate 122 and the drive block 120, and the connecting block 121 is slidably connected to the vertical slide groove 10. The arc-shaped plate 122 is fixed to the end block 30, which can better fit the shape of the end block 30 and enhance the stability of the connection. The drive block 120 is threadedly connected to the lead screw 13 to realize power transmission, and the connecting block 121 slides along the vertical slide groove 10 to provide guidance for the movement of the movable plate 12. The cooperation of the three makes the movable plate 12 more stable during the up and down movement, avoids deviation, and ensures the accuracy of nozzle height adjustment.

[0031] In a preferred embodiment, a hinge seat 7 is fixed near the bottom of the outer circumference of the vertical pipe 6, and the nozzle 8 is hinged to the inner wall of the hinge seat 7 via a connecting shaft 80 integrally formed on its outer wall. This allows the nozzle 8 to rotate around the connecting shaft 80, enabling flexible adjustment of the spray angle.

[0032] In a preferred embodiment, a chuck 70, coaxially fixed to the connecting shaft 80, is rotatably mounted on one side of the outer wall of the hinge 7. Several slots 73 are formed on the outer circumference of the chuck 70. These slots 73, in conjunction with positioning components, can fix the angle of the nozzle 8. Once the nozzle 8 is adjusted to a suitable angle, the slots 73 quickly lock the current angle, preventing angular displacement of the nozzle 8 due to external forces during spraying and ensuring the stability of the spraying direction.

[0033] In a preferred embodiment, a fixing block 71 is fixed to the outer wall of the hinge 7 above the chuck 70. A positioning bolt 72 is threaded onto the fixing block 71. When the positioning bolt 72 is tightened on the fixing block 71, its bottom engages with the slot 73. When the positioning bolt 72 is tightened on the fixing block 71, its bottom engages with the slot 73 of the chuck 70, which can firmly lock the position of the chuck 70, thereby fixing the spray angle of the nozzle 8.

[0034] When using the precision drip irrigation nozzle for tea garden fertilization, the nozzle is connected to the fertilizer supply main pipeline via the flange 20 at the top of the upper connecting pipe 2. The flange connection ensures the sealing and firmness of the connection, prevents fertilizer solution leakage, and provides convenience for subsequent disassembly and maintenance.

[0035] During height adjustment, the operator rotates the adjustment knob 14 on the top of the lead screw 13 (the anti-slip texture enhances hand friction, making operation easier), causing the lead screw 13 to rotate on the side plate 11. Since the lead screw 13 is threadedly connected to the drive block 120 of the movable plate 12, and the connecting block 121 of the movable plate 12 slides along the vertical groove 10 of the L-shaped mounting bracket 1, the rotation of the lead screw 13 drives the movable plate 12 to move up and down. The arc-shaped plate 122 of the movable plate 12 is fixed to the lower end block 30, thereby causing the lifting corrugated pipe 3 to extend and retract, achieving height adjustment of the lower connecting pipe 4 and the entire lower structure of the nozzle, adapting to tea trees of different growth heights and ensuring that fertilizer is sprayed at the appropriate location.

[0036] In terms of flow control, the fertilizer solution in the fertilizer supply pipeline enters the lower connecting pipe 4 through the upper connecting pipe 2 and the rising corrugated pipe 3, and then is diverted through horizontal pipes 5 of different diameters between the lower connecting pipe 4 and the vertical pipe 6. Operators can control the flow rate of fertilizer solution into the vertical pipe 6 by opening the manual valve 50 on the corresponding horizontal pipe 5 according to the fertilization needs of different tea trees or areas, thus achieving on-demand fertilization.

[0037] During angle adjustment, the nozzle 8 is hinged to the hinge seat 7 at the bottom of the vertical pipe 6 via the connecting shaft 80, allowing it to rotate around the connecting shaft 80 to adjust the spray direction. Once the desired angle is achieved, rotate the chuck 70 on one side of the hinge seat 7 (coaxially fixed with the connecting shaft 80 and rotating synchronously with the nozzle 8) to align the slot 73 on the chuck 70 with the positioning bolt 72 below the fixing block 71. Tighten the positioning bolt 72 so that its bottom inserts into the slot 73, locking the chuck 70 in place and thus fixing the angle of the nozzle 8, preventing angle deviation due to external forces during spraying. Simultaneously, rotating the bellows 9 can assist in fine-tuning the nozzle 8 angle, further improving the accuracy of the spray direction.

[0038] Through the synergistic effect of the above-mentioned components, the nozzle achieves multi-dimensional precise control of height, flow rate, and angle, ensuring that the fertilizer solution is efficiently and accurately dripped into the required areas of the tea garden, meeting the needs of refined fertilization in the tea garden.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
