Description

Technical Field

[0001] This utility model relates to the field of irrigation equipment for facility agriculture, and more specifically, to an irrigation device for facility agriculture. Background Technology

[0002] Irrigation is an artificial supplement to insufficient natural rainfall. Natural rainfall is unevenly distributed seasonally and geographically; irrigation can combat drought, ensure crops receive the necessary water during critical growth stages, and guarantee stable harvests. Precise water control can also improve the quality of agricultural products (such as fruit size and taste). Furthermore, methods like the "tea-growing-inducing method" used in tea gardens, which regulates the harvest period through irrigation, allow tea leaves to be marketed earlier, generating higher economic benefits. For greenhouse and other facility agriculture, irrigation is the cornerstone of environmentally controlled cultivation. It makes agricultural production possible in water-scarce areas and during off-seasons, truly achieving "drought and flood-resistant yields." However, existing technologies have the following problems: mud, organic matter, or fertilizer residue in irrigation water can easily accumulate in the dripper channel, causing dripper blockage, requiring frequent disassembly and cleaning, increasing labor costs and affecting irrigation continuity. Utility Model Content

[0003] One objective of this invention is to provide a new technological solution for irrigation devices in facility agriculture.

[0004] According to a first aspect of this utility model, an irrigation device for facility agriculture is provided, including an inlet pipe, an inlet at one end of the inlet pipe, an outlet at the other end of the inlet pipe, a filter pipe connected to the outlet of the inlet pipe, a plurality of arc-shaped buffer ribs fixedly arranged inside the inlet pipe, a guide plate installed on the right end of the arc-shaped buffer ribs, a primary filter box and a secondary filter box arranged on the filter pipe, a conical filter screen installed on one inner wall of the primary filter box, and a rotating filter cylinder arranged inside the secondary filter box.

[0005] Optionally, a primary sludge collection hopper is provided at the bottom of the primary filter box, which is used to collect the impurities filtered in the primary filter box to the bottom of the primary filter box, and a primary sewage discharge pipe is connected to the bottom of the primary filter box.

[0006] Optionally, a secondary sludge collection hopper is provided at the bottom of the secondary filter box. The secondary sludge collection hopper is used to collect the impurities filtered in the secondary filter box to the bottom of the secondary filter box. A secondary sewage discharge pipe is connected to the bottom of the secondary filter box. A scraper is fixedly installed on the inner wall of the top of the secondary filter box. The scraper is in contact with the outer surface of the rotating filter cartridge.

[0007] Optionally, the primary sewage pipe and the secondary sewage pipe are designed as an integrated unit, and the bottom is connected to a sewage outlet.

[0008] Optionally, a rotating rod is provided inside the filter pipe. One end of the rotating rod extends into the outlet of the water inlet pipe and is fixedly connected to an impeller. The other end of the rotating rod extends into one end of the filter pipe. Bearing seats are rotatably installed at both ends of the rotating rod, and the bearing seats are fixedly installed on the inner wall of the filter pipe.

[0009] Optionally, the rotating filter cartridge disposed inside the secondary filter box is fixedly mounted on the rotating rod, and the rotating filter cartridge rotates through the cooperation of the rotating rod and the impeller.

[0010] According to one embodiment of this disclosure, in a facility agriculture irrigation device, irrigation water enters through an inlet pipe, is first buffered and slowed down by arc-shaped buffer ribs, and then guided to a filter pipe by a guide plate. The water flow first passes through the conical filter screen of the primary filter box to intercept large particles of impurities, which fall into the primary collection hopper and are discharged through the integrated sewage pipe. Subsequently, the water flow impacts the impeller, driving the rotating rod and the rotating filter cylinder of the secondary filter box to rotate. The filter cylinder intercepts fine impurities through centrifugal force, and the scraper simultaneously scrapes off impurities from the surface of the filter cylinder. The impurities fall into the secondary collection hopper and are also discharged through the integrated sewage pipe. Finally, the clean water flow is transported along the filter pipe to the drippers and other components to complete irrigation, thereby solving the problem of dripper clogging, which requires frequent disassembly and cleaning, increases labor costs, and affects the continuity of irrigation.

[0015] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0016] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0017] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0018] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0019] like Figure 1-4 As shown, an agricultural irrigation device includes an inlet pipe 1. One end of the inlet pipe 1 has an inlet for introducing water, ensuring smooth water flow into the pipeline system. The other end of the inlet pipe 1 has an outlet for discharging water, which connects to a subsequent filter pipe 2 to ensure smooth water flow into the filtration stage. Several arc-shaped buffer ribs 6 are fixedly installed inside the inlet pipe 1. These evenly distributed arc-shaped buffer ribs 6 are designed to slow down the water flow velocity and reduce the impact force of the water flow. At the right end of the arc-shaped buffer rib 6, a guide plate 7 is installed to guide the water flow direction. The guide plate 7 can effectively guide the water flow to the filter pipe 2. The filter pipe 2 is equipped with a primary filter box 3 and a secondary filter box 4 in sequence. A conical filter screen 301 is installed on one inner wall of the primary filter box 3. The conical filter screen 301 is mainly used for preliminary filtration of larger impurity particles. The secondary filter box 4 is equipped with a rotatable filter cylinder. The rotatable filter cylinder 401 can further finely filter the tiny impurities in the water flow to ensure that the water quality reaches a higher purification standard.

[0020] like Figures 1 to 4As shown, a primary sludge collection hopper 302 is provided at the bottom of the primary filter box 3. The primary sludge collection hopper 302 is used to collect the impurities filtered in the primary filter to the bottom of the primary filter box 3. The bottom of the primary filter box 3 is connected to a primary sewage discharge pipe 303.

[0021] Furthermore, the primary filter box 3 is equipped with a primary sludge collection hopper 302 at its bottom. The main function of the primary sludge collection hopper 302 is to effectively collect and store various larger impurities generated during the primary filtration process in the bottom area of ​​the primary filter box 3. This design ensures that impurities will not re-enter the water flow during the filtration process, thereby improving filtration efficiency. In addition, the bottom of the primary filter box 3 is also connected to a dedicated primary sewage discharge pipe 303. The function of this pipe is to discharge the impurities concentrated in the primary sludge collection hopper 302 through the pipe, so as to facilitate subsequent cleaning and maintenance work and ensure the normal operation and long-term stability of the entire filtration system. like Figures 1 to 4 As shown, a secondary sludge collection hopper 402 is provided at the bottom of the secondary filter box 4. The secondary sludge collection hopper 402 is used to collect the impurities filtered in the secondary filter box 4 at the bottom. A secondary sewage discharge pipe 403 is connected to the bottom of the secondary filter box 4. A scraper 404 is fixedly installed on the inner wall of the top of the secondary filter box 4. The scraper 404 is in contact with the outer surface of the rotating filter cylinder 401.

[0022] Furthermore, the secondary filter box 4 is equipped with a secondary sludge collection hopper 402 at its bottom. The main function of the secondary sludge collection hopper 402 is to effectively collect and deposit various fine impurities generated during the secondary filtration process into the bottom area of ​​the secondary filter box 4, ensuring that the impurities do not re-mix into the filter medium. In addition, a secondary drain pipe 403 is designed and connected to the bottom of the secondary filter box 4. Through this pipe, the impurities concentrated in the secondary sludge collection hopper 402 can be easily discharged from the system, thereby maintaining the cleanliness of the filter box and the filtration efficiency. On the top inner wall of the secondary filter box 4, a scraper 404 is fixedly installed. The design of this scraper 404 allows it to be in close contact with the outer surface of the rotating filter cartridge 401. As the rotating filter cartridge 401 rotates, the scraper 404 can effectively scrape off the deposits on the outer surface of the filter cartridge, further ensuring the smoothness and efficiency of the filtration process. like Figures 1 to 4 As shown, the primary sewage pipe 303 and the secondary filter pipe 2 are designed as an integrated unit, and the bottom is connected to a sewage outlet 5.

[0023] Furthermore, the primary sewage pipe 303 and the secondary filter pipe 2 adopt an integrated design concept. The two are closely connected in structure to form an organic whole. In addition, the bottom of these two pipes is specially designed and connected to a dedicated sewage outlet 5 so that the sewage can be discharged efficiently and smoothly during the sewage discharge and filtration process, ensuring the operating efficiency and cleaning effect of the entire system. This design not only improves the synergy between sewage discharge and filtration, but also greatly simplifies the difficulty of maintenance and management. like Figures 1 to 4 As shown, a rotating rod 9 is provided inside the filter pipe 2. One end of the rotating rod 9 extends into the outlet of the water inlet pipe 1 and is fixedly connected to an impeller 8. The other end of the rotating rod 9 extends into one end of the filter pipe 2. Bearing seats 10 are rotatably installed at both ends of the rotating rod 9. The bearing seats 10 are fixedly installed on the inner wall of the filter pipe 2.

[0024] Furthermore, a rotating rod 9 is installed inside the filter pipe 2. One end of the rotating rod 9 extends into the outlet of the water inlet pipe 1, and an impeller 8 is fixedly connected to this end. The impeller 8 rotates under the action of the irrigation water flow, thereby driving the rotating rod 9 to rotate. The other end of the rotating rod 9 extends to one end of the filter pipe 2, ensuring that the overall length of the rotating rod 9 covers the main area of ​​the filter pipe 2. In order to ensure that the rotating rod 9 can rotate smoothly, bearing seats 10 are installed at both ends. These bearing seats 10 not only provide support points for the rotation of the rotating rod 9, but also reduce the friction during the rotation process. The bearing seats 10 are fixedly installed on the inner wall of the filter pipe 2 to ensure that they will not be displaced during use, thereby ensuring the stable operation of the entire rotating system. like Figures 1 to 4 As shown, the rotating filter cartridge 401, which is located inside the secondary filter box 4, is fixedly mounted on the rotating rod 9.

[0025] Furthermore, the rotating filter cartridge 401 is securely placed inside the secondary filter box 4 and tightly installed on the rotating rod 9 by a special fixing device to ensure that it will not shift or loosen during operation. Then, the impeller 8 drives the rotating rod 9 to rotate, and the scraper 404 scrapes off the surface deposits. This design can continuously remove impurities from the surface of the filter cartridge and avoid the filtration effect being affected by the accumulation of impurities.

[0026] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
