Description

Technical Field

[0001] This utility model relates to the field of strawberry seedling technology, and more specifically, to a strawberry seedling irrigation device. Background Technology

[0002] Strawberries are perennial herbaceous plants belonging to the genus *Fragaria* of the Rosaceae family. Originally from South America, they are now widely cultivated throughout China and Europe. They thrive in fertile, loose, neutral or slightly acidic soil. With societal development, the demand for strawberries continues to rise. To meet market supply, greenhouse cultivation has become the mainstream method. During the strawberry seedling stage, drip irrigation systems are needed to water the seedlings.

[0003] Some existing irrigation devices have non-adjustable flow rates, which cannot meet the differentiated water requirements of strawberry seedlings during the cotyledon, true leaf, and hardening stages. This can easily lead to poor seedling growth due to water shortage or root rot due to excessive water, and can easily induce diseases. During the strawberry seedling cultivation stage, the planting density needs to be adjusted according to the seedling growth status, but most existing irrigation devices are fixed structures, which are difficult to adapt to the adjustment requirements of strawberry planting density. Therefore, this utility model provides a strawberry seedling irrigation device to solve the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a strawberry seedling irrigation device with the advantages of adjustable irrigation flow and irrigation position.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a strawberry seedling irrigation device, comprising: a support structure, wherein the support structure includes a support frame, and the support frame is provided in two sets, and a water supply pipe and a slide rail are fixedly connected to the opposite side surface of the two sets of support frames, the water supply pipe is connected to an inlet pipe inside the side wall away from the slide rail, and a fixing hole is provided inside the upper surface of the slide rail, and multiple sets of fixing holes are provided. The irrigation structure is provided in multiple sets, and the irrigation structure includes a connecting hose, an adjusting seat, an adjusting hole, an irrigation pipe, a threaded seat and an adjusting column. One end of each of the multiple sets of connecting hoses is connected to the interior of the upper surface of the water supply pipe. The fixed structure includes multiple sets of sliding blocks, connecting rods, fixing pins, compression springs, and pull plates. The multiple sets of sliding blocks are slidably connected to the outer surface of the slide rail, and the outer surface of one side of the multiple sets of sliding blocks is fixedly connected to the outer surface of the multiple sets of adjusting seats near the slide rail.

[0006] As a preferred embodiment of this utility model, the other end of the connecting hose is connected to the interior of the upper surface of the adjusting seat near the slide rail. A sealing ring is fixedly connected to the upper surface inside the adjusting seat. The adjusting hole is opened inside the lower surface of the adjusting seat, and the interior of the adjusting hole is conical.

[0007] As a preferred embodiment of this utility model, a connecting seat is fixedly connected to the lower surface of the adjusting seat, and the interior of the connecting seat is connected to the interior of the adjusting hole. The pouring pipe is connected to the interior of the connecting seat, and a pouring nozzle is connected to the interior of the lower surface of the pouring pipe.

[0008] As a preferred embodiment of this utility model, the threaded seat is fixedly connected to the upper surface of the adjusting seat, the adjusting column is threadedly connected to the inside of the threaded seat, the outer surface of the lower end of the adjusting column is in contact with the inner surface of the adjusting hole, and a sealing gasket is fixedly connected to the lower end of the outer surface of the adjusting column.

[0009] As a preferred embodiment of this utility model, a fixed seat is fixedly connected to the upper surface of the slide block, and a connecting rod is slidably inserted into the interior of the upper surface of the fixed seat. The lower end of the connecting rod is fixedly connected to the upper surface of the fixing pin, and the lower end of the fixing pin is inserted into the interior of the fixing hole.

[0010] As a preferred embodiment of this utility model, the compression spring is disposed inside the fixed base, and the upper and lower ends of the compression spring elastically abut against the upper surface inside the fixed base and the upper surface of the fixing pin, respectively.

[0011] As a preferred embodiment of this utility model, a fixing rod is fixedly connected to the inside of the upper end of the connecting rod, and pull plates are fixedly connected to both ends of the fixing rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model allows the lower end of the rotating adjusting column to move longitudinally inside the adjusting hole. When the lower end of the adjusting column moves, a gap is created between its outer surface and the inner surface of the adjusting hole. The gap gradually widens when the adjusting column moves upward and gradually narrows when it moves downward. Thus, the flow rate of water through the adjusting hole can be adjusted using the adjusting column. This design allows the water volume during irrigation to be adjusted according to the actual situation. 2. This utility model allows the connecting rod to move upward inside the fixed base by pulling the pull plate, which in turn moves the fixing pin synchronously. When the fixing pin moves, its lower end will disengage from the fixing hole. At this time, the slide can be pulled to slide on the outer surface of the slide rail. When the slide moves, it can drive the entire pouring structure to move synchronously. After releasing the pull plate, the compression spring will push the connecting rod and the fixing pin back to their original positions through its own elasticity. At this time, the lower end of the fixing pin will re-insert into the fixing hole, thereby fixing the position of the fixed structure and the pouring structure as a whole. This design allows the position of multiple pouring structures to be flexibly adjusted according to the actual situation during use. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 5As shown, this utility model provides a strawberry seedling irrigation device, including: a support structure 1, the support structure 1 including a support frame 11, and the support frame 11 is provided in two sets, and a water supply pipe 12 and a slide rail 14 are fixedly connected on the opposite side surface of the two sets of support frames 11. The water supply pipe 12 is connected to the inside of the side wall away from the slide rail 14 by a water inlet pipe 13. The upper surface of the slide rail 14 is provided with a fixing hole 15, and multiple sets of fixing holes 15 are provided. The support frame 11 is made of 304 stainless steel, with a height of 80-100cm and a span of 1.2-1.5m. The distance between the two sets of support frames is adapted to the width of the strawberry seedling bed. The water supply pipe 12 is made of PVC with a diameter of 25mm and is fixed to the support frame 11 with M8 bolts. The slide rail 14 is a U-shaped aluminum alloy rail with a cross-sectional width of 20mm and is fixed to the support frame 11 by welding. The fixing holes 15 have a diameter of 8mm, a hole spacing of 8cm, and a hole depth of 15mm, and are evenly distributed along the length of the slide rail 14.

[0017] The irrigation structure 2 is provided with multiple sets, and includes a connecting hose 21, an adjusting seat 22, an adjusting hole 24, an irrigation pipe 26, a threaded seat 28 and an adjusting column 29. One end of each of the multiple sets of connecting hoses 21 is connected to the interior of the upper surface of the water supply pipe 12. The fixing structure 3 is provided in multiple sets and includes a slide 31, a connecting rod 33, a fixing pin 34, a compression spring 35 and a pull plate 37. The multiple sets of slides 31 are slidably connected to the outer surface of the slide rail 14, and the outer surface of one side of the multiple sets of slides 31 is fixedly connected to the outer surface of the multiple sets of adjusting seats 22 near the slide rail 14.

[0018] The other end of the connecting hose 21 is connected to the interior of the upper surface of the adjusting seat 22 near the slide rail 14. A sealing ring 23 is fixedly connected to the upper surface inside the adjusting seat 22. The adjusting hole 24 is opened inside the lower surface of the adjusting seat 22, and the interior of the adjusting hole 24 is conical.

[0019] Water from the water supply pipe 12 can be transported to the regulating seat 22 via the connecting hose 21. The connecting hose 21 is made of TPU, which has the advantages of high elasticity and lightweight. It has strong bending resistance and can quickly rebound after repeated bending, which can prevent water flow blockage due to bending. It also has the characteristics of aging resistance and slight corrosion resistance.

[0020] The lower surface of the adjusting seat 22 is fixedly connected to the connecting seat 25, and the interior of the connecting seat 25 is connected to the interior of the adjusting hole 24. The pouring pipe 26 is connected to the interior of the connecting seat 25, and the interior of the lower surface of the pouring pipe 26 is connected to the pouring nozzle 27.

[0021] The water source inside the regulating seat 22 can be transported to the connecting seat 25 and the irrigation pipe 26 through the regulating hole 24. The water source inside the irrigation pipe 26 will flow out through the irrigation nozzle 27 to irrigate the strawberry seedlings.

[0022] The threaded seat 28 is fixedly connected to the upper surface of the adjusting seat 22, the adjusting column 29 is threadedly connected to the inside of the threaded seat 28, the outer surface of the lower end of the adjusting column 29 is attached to the inner surface of the adjusting hole 24, and a sealing washer 210 is fixedly connected to the lower end of the outer surface of the adjusting column 29.

[0023] The adjusting column 29 can be moved longitudinally inside the adjusting seat 22 by rotating it. The upper end of the adjusting column 29 is equipped with a handle, and the outer surface of the handle is provided with anti-slip texture to effectively prevent the hand from slipping during rotation. When the lower end of the adjusting column 29 moves, a gap will be generated between its outer surface and the inner surface of the adjusting hole 24. The adjusting column 29 and the adjusting hole 24 change the fitting clearance through axial movement. The clearance change is linear gradient, which can realize continuous and fine adjustment of the flow rate from small to large, and can accurately match different growth stages of strawberry seedlings. The thread of the adjusting column 29 and the threaded seat 28 is M12×1.5. The taper of the lower end of the adjusting column is 1:5, which is consistent with the taper of the tapered adjusting hole 24. The sealing gasket 210 is made of nitrile rubber with a thickness of 3mm to ensure that the adjusting column and the adjusting hole fit and seal.

[0024] Among them, a fixed seat 32 is fixedly connected to the upper surface of the slide 31, and a connecting rod 33 is slidably inserted into the interior of the upper surface of the fixed seat 32. The lower end of the connecting rod 33 is fixedly connected to the upper surface of the fixing pin 34, and the lower end of the fixing pin 34 is inserted into the interior of the fixing hole 15.

[0025] By pulling the slide block 31, it can slide on the outer surface of the slide rail 14. When the slide block 31 moves, it can drive the fixed structure 3 and the pouring structure 2 to move synchronously. The clearance between the slide block 31 and the slide rail 14 is 0.1-0.2mm, which ensures that the slide block 31 slides smoothly and without lateral wobbling.

[0026] The compression spring 35 is located inside the fixed base 32, and its upper and lower ends elastically abut against the upper surface inside the fixed base 32 and the upper surface of the fixing pin 34, respectively.

[0027] The compression spring 35 can continuously apply a downward force to the fixing pin 34, which can prevent the fixing pin 34 from coming out of the fixing hole 15 during use and improve the stability of the fixing pin 34 when fixing the overall position of the fixing structure 3 and the pouring structure 2.

[0028] Among them, a fixing rod 36 is fixedly connected to the upper end of the connecting rod 33, and a pull plate 37 is fixedly connected to both ends of the fixing rod 36.

[0029] By pulling the pull plate 37, the connecting rod 33 and the fixing pin 34 can be moved upward through the fixing rod 36. At this time, the lower end of the fixing pin 34 can be disengaged from the inside of the fixing hole 15. At this time, the operator can pull the slide 31 to adjust its position.

[0030] The working principle and usage process of this utility model are as follows: First, pull the pull plate 37 to disengage the fixing pin 34 from the fixing hole 15 of the slide rail 14, push the slide seat 31 to drive the adjusting seat 22 of the irrigation structure 2 to slide to the position suitable for the strawberry planting density, release the pull plate 37, and the compression spring 35 pushes the fixing pin 34 to re-insert into the fixing hole 15 to complete the position fixation; then connect the external water source to the water inlet pipe 13, and the water source enters the adjusting seat 22 through the water supply pipe 12 and the connecting hose 21. Then rotate the adjusting column 29 in the threaded seat 28 so that its lower end moves longitudinally in the conical adjusting hole 24 to change the gap size. Moving it upwards expands the gap and moving it downwards shrinks the gap. The sealing gasket 210 ensures a seal. After adjusting to the flow rate suitable for the needs of the strawberry seedlings, the water source flows into the irrigation pipe 26 through the adjusting hole 24 and the connecting seat 25, and finally irrigates the strawberry seedlings through the irrigation nozzle 27. Subsequently, the above position and flow rate adjustment steps can be repeated according to the growth status of the seedlings or changes in the planting density.
