Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to an irrigation spraying device for cut flower planting. Background Technology

[0002] In the field of cut flower cultivation, precise irrigation is crucial. Spraying, as a commonly used irrigation method, can simulate natural rainfall, evenly moisturizing flowers and soil, maintaining the plant's water balance, and promoting healthy growth of cut flowers. At the same time, scientific spraying irrigation can also avoid root diseases caused by overwatering, improving the quality and yield of flowers.

[0003] Utility model patent CN217936746U discloses an agricultural irrigation sprinkler. This sprinkler includes a connecting pipe and a sprinkler head. A mixing chamber is fixedly connected to the connecting pipe, and the mixing chamber is equipped with a mixing mechanism, which includes a motor body, a rotating shaft, and a mixing rod. In use, water is transported through the connecting pipe. As the water passes through the mixing chamber, the mixing mechanism agitates the pesticide-water mixture, breaking up any incompletely mixed solid particles to prevent clogging of the sprinkler head. Simultaneously, a filter chamber and filter screen structure ensure filtration of the pesticide-water mixture, preventing particles from entering the sprinkler head. This ensures good stability in the agricultural irrigation process and meets usage requirements.

[0004] This device primarily relies on a mixing mechanism within the mixing chamber to break up incompletely mixed solid particles of the pesticide, and a filter chamber and filter screen to filter the pesticide-water mixture. However, this method only pre-treats the pesticide before irrigation and cannot solve the problem of clogging caused by solid pesticide residue adhering to the spray head end caps and other parts during irrigation. Even small particles that penetrate the filter screen and enter the spray head can still cause blockage, affecting irrigation efficiency. Therefore, we propose an irrigation sprinkler system for cut flower cultivation. Utility Model Content

[0005] The purpose of this invention is to provide an irrigation sprinkler device for cut flower cultivation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fresh-cut flower planting irrigation sprinkler device includes a sprinkler head body. An end cap for forming a spray water flow is threadedly connected to the head of the sprinkler head body. A protruding tube is provided at the tail end of the sprinkler head body. A water pipe is connected to the tail end of the protruding tube. A cleaning mechanism is provided inside the sprinkler head body. The cleaning mechanism includes a rotating shaft that can rotate axially inside the sprinkler head body and two brush rods installed at the head end of the rotating shaft and capable of rotating around the rotating shaft.

[0008] The head of the rotating shaft is rotatably connected to the end cap. A propeller is coaxially connected to the rotating shaft. The propeller is located inside the spray head body. The flow of water washes over the propeller, causing the propeller to drive the rotating shaft to rotate axially.

[0009] The two brush rods are located on the inner and outer sides of the end cap, respectively. Each brush rod has a number of bristles that abut against the head end of the end cap. A connecting post is located at the middle of the brush rod, and the connecting post is sleeved on the rotating shaft and fixedly connected to the rotating shaft.

[0010] Preferably, the head of the end cap is provided with a sealing plate, and the sealing plate is provided with a plurality of spray grooves;

[0011] In this setup, water is sprayed from the sprinkler trough to form a spray stream that can meet the irrigation needs of cut flowers.

[0012] Preferably, the distance between the outer diameter of the propeller and the inner wall of the spray head body is 2-3mm, so that the gap formed between the outermost outer edge of the propeller and the inner wall of the spray head body reduces water loss;

[0013] In this setting, the reasonable spacing reduces water leakage, improves the propeller's efficiency in absorbing water energy, and ensures stable rotation of the shaft.

[0014] Preferably, the propeller blades are provided with guide grooves, which are distributed in a spiral shape to guide the water flow to impact the propeller more smoothly.

[0015] In this configuration, the spiral guide channel optimizes the water flow path, enhances the impact of the water flow on the propeller, and makes the shaft rotate more efficiently.

[0016] Preferably, the first end of the rotating shaft is threaded with a stop cap, and a stop post is provided on the rotating shaft between the stop cap and the propeller, and both of the connecting posts are clamped between the stop cap and the stop post;

[0017] In this configuration, the clamping and fixing of the abutment and the abutment post to the connecting post enhances the stability of the connection between the brush rod and the rotating shaft.

[0018] Preferably, the outer end face of the connecting post is provided with a protruding post, the two connecting posts on the two brush rods are symmetrical, and the two protruding posts on the two connecting posts abut against each other;

[0019] In this design, the symmetrical abutment design of the protruding pillars enhances the connection rigidity between the brush handles and ensures full contact between the bristles and the end caps.

[0020] Preferably, the tail end of the rotating shaft is provided with a cross-shaped limiting frame, and a sleeve post is provided inside the limiting frame. The tail end of the rotating shaft is inserted into the sleeve post and rotatably connected to the sleeve post. The outer side of the limiting frame is fixedly connected to the convex tube.

[0021] In this setup, the limit bracket and sleeve restrict the movement trajectory of the rotating shaft to prevent it from shifting or shaking during rotation, and the fixed connection with the convex tube ensures that the cleaning mechanism is installed securely.

[0022] Preferably, the bristles on the brush handle are made of flexible nylon material, and the hardness of the bristles gradually decreases from the brush handle towards the end cap, so that several bristles can completely cover the spray groove on the end cap in a natural state.

[0023] In this setup, the flexible nylon bristles with gradually varying hardness effectively remove impurities without damaging the end cap surface, while the full-coverage spray channel ensures no cleaning dead spots.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This fresh-cut flower planting irrigation sprinkler device achieves dynamic real-time cleaning through a cleaning mechanism. During irrigation, the water flow washes the propeller, which drives the rotating shaft and brush rod to rotate, so that the bristles on the brush rod continuously clean the spray groove on the end cover. This can promptly remove solid particles of medicine attached to the spray groove and prevent the spray head from clogging. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Please see Figures 1-8 A sprinkler irrigation device for cut flower cultivation includes a sprinkler head body 1. An end cap 12 for forming a spray water flow is threadedly connected to the head of the sprinkler head body 1. A protruding tube 11 is provided at the tail end of the sprinkler head body 1, and a water pipe 2 is connected to the tail end of the protruding tube 11. A sealing plate 121 is provided at the head of the end cap 12, and several spray grooves 122 are formed on the sealing plate 121. The protruding tube 11 is connected to the water pipe 2 to achieve stable water delivery, allowing water to be sent into the sprinkler head body 1 by the water pipe 2. Under the action of the spray grooves 122, the water flows out from the spray grooves 122, achieving the purpose of irrigation.

[0040] like Figure 2 , Figure 3 and Figure 5 As shown, in this utility model, a cleaning mechanism 3 is provided inside the spray head body 1. The cleaning mechanism 3 includes a rotating shaft 31 that can rotate axially inside the spray head body 1 and two brush rods 32 installed at the head end of the rotating shaft 31 and capable of rotating around the rotating shaft 31.

[0041] like Figures 1-3 , Figure 5 and Figure 6As shown, specifically, the head of the rotating shaft 31 is rotatably connected to the end cap 12. A propeller 311 is coaxially connected to the rotating shaft 31. The propeller 311 is located inside the spray head body 1. The flow of water washes the propeller 311, causing the propeller 311 to drive the rotating shaft 31 to rotate axially. When water flows through the spray head body 1, the propeller 311 uses the impact force of the water flow to convert water energy into the rotational kinetic energy of the rotating shaft 31, providing sustainable power for the cleaning mechanism 3. No external power supply or complex drive device is required, reducing energy consumption and maintenance costs.

[0042] like Figure 3 and Figure 4 As shown, furthermore, the distance between the outer diameter of the propeller 311 and the inner wall of the spray head body 1 is 2-3 mm, which reduces water loss due to the gap formed between the outermost edge of the propeller 311 and the inner wall of the spray head body 1, effectively reducing water leakage and improving energy utilization. The blade surface of the propeller 311 is provided with guide grooves 3111, which are spirally distributed. These guide grooves guide the water flow to impact the propeller 311 more smoothly. The spiral guide grooves 3111 optimize the water flow path, enhance the impact force of the water flow on the propeller 311, and enable the shaft 31 to rotate efficiently.

[0043] like Figure 2 , Figure 3 , Figures 5-7 As shown, two brush rods 32 are located on the inner and outer sides of the end cap 12, respectively. Each brush rod 32 has several bristles that abut against the head of the end cap 12. A connecting post 321 is located at the middle of the brush rod 32, and is fitted onto the rotating shaft 31 and fixedly connected to it. A stop cap 313 is threaded onto the head of the rotating shaft 31. A stop post 312 is located on the rotating shaft 31 between the stop cap 313 and the propeller 311. Both connecting posts 321 are clamped between the stop cap 313 and the stop post 312. The clamping and fixing of the connecting post 321 by the stop cap 313 and the stop post 312 enhances the stability of the brush rod 32 installation. By tightening the stop cap 313, the brush rod 32 can be securely connected to the rotating shaft 31 via the connecting post 321, ensuring that the brush rod 32 can rotate synchronously with the rotating shaft 31. When the brush rod 32 is driven to rotate by the rotating shaft 31, the brush bristles are in close contact with the end cap 12, which allows the brush bristles on the brush rod 32 to remove solid particles, impurities and other residues on the surface of the end cap 12 and inside the spray tank 122, thus preventing the spray tank 122 from becoming clogged.

[0044] like Figure 7As shown, it is worth noting that the outer end face of the connecting post 321 is provided with a protruding post 322. The two connecting posts 321 on the two brush rods 32 are symmetrical, so that the two brush rods 32 form a stable connection structure and enhance the overall rigidity. The two protruding posts 322 on the two connecting posts 321 abut against each other. The sealing plate 121 is sleeved on the outside of the cylinder formed by the two protruding posts 322 after abutting. The total height of the two protruding posts 322 is greater than the thickness of the sealing plate 121. After the two protruding posts 322 abut against each other, it not only restricts the radial movement of the brush rods 32, but also prevents the sealing plate 121 from creating resistance to the rotation of the connecting post 321 driven by the rotating shaft 31. This ensures that the bristles are in full contact with the end cap 12 while allowing the cleaning mechanism 3 to rotate smoothly.

[0045] It should be added that the bristles on the brush handle 32 are made of flexible nylon. Flexible nylon bristles have good flexibility and abrasion resistance, effectively removing impurities without scratching the surface of the end cap 12. The hardness of the bristles gradually decreases from the brush handle 32 towards the end cap 12, allowing the bristles to fit more tightly against the end cap 12. In its natural state, several bristles can completely cover the spray grooves 122 on the end cap 12, ensuring that the spray grooves 122 are thoroughly cleaned by the brush handle 32 and preventing incomplete cleaning of the spray grooves 122.

[0046] like Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, the tail end of the rotating shaft 31 is provided with a cross-shaped limiting frame 33, and a sleeve 331 is provided inside the limiting frame 33. The tail end of the rotating shaft 31 is inserted into the sleeve 331 and rotatably connected to the sleeve 331. The outer side of the limiting frame 33 is fixedly connected to the protruding tube 11. The limiting frame 33 and the sleeve 331 constitute a stable limiting support structure, which accurately limits the movement trajectory of the rotating shaft 31 and prevents it from deviating or shaking during rotation.

[0047] In this embodiment, the irrigation sprinkler device for cut flower planting is used as follows: First, the water pipe 2 delivers water to the convex pipe 11 so that the water flows into the sprinkler head body 1. The water that enters the sprinkler head body 1 is finally sprayed out from the sprinkler trough 122 to form a spray water flow. Then, as the water flows, the water flow impacts the propeller 311, causing the propeller 311 to drive the rotating shaft 31 to rotate axially within the sprinkler head body 1. Finally, when the rotating shaft 31 rotates, it drives the two brush rods 32 located on the inner and outer sides of the end cover 12 to rotate around the rotating shaft 31 through the connecting column 321. This causes the bristles on the brush rods 32 to start cleaning the sealing plate 121 on the end cover 12 synchronously inside and out, thereby cleaning the sprinkler trough 122 and preventing the sprinkler head body 1 from being blocked.

[0048] 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
