Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation technology and relates to a farmland drainage and irrigation device, especially a small farmland drainage and irrigation device with filtration function. Background Technology

[0002] Small farmlands have limited water absorption and drainage capacity, often requiring irrigation and drainage systems after heavy rains during the rainy season to ensure the normal growth of crops. Furthermore, during the crop harvesting stage, timely irrigation and drainage are also necessary if heavy rains occur. Existing irrigation and drainage systems typically use pipes and pumps to directly draw water from the farmland into storage tanks. During this process, weeds and mud are easily sucked into the pipes, clogging them and even damaging the pumps. While some irrigation gates have filter baffles, their direct application to irrigation and drainage systems is impractical. Therefore, it is necessary to provide an irrigation and drainage device suitable for small farmlands that effectively prevents weeds and other impurities from clogging pipes and damaging pumps. Utility Model Content

[0003] The purpose of this utility model is to provide a small farmland irrigation and drainage device with filtration function to solve the technical problems of easy blockage of water pumping pipes and easy damage to water pumps due to impurities in the existing technology.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows: A small farmland irrigation and drainage device with filtration function includes a mobile frame, a water storage tank, an irrigation and drainage unit, a filtration unit and an irrigation unit mounted on the mobile frame. The water outlet of the irrigation and drainage unit is connected to the water inlet of the water storage tank, and the irrigation unit is connected to the water outlet of the water storage tank. The filtration unit is located at the front end of the irrigation and drainage unit and is connected to the water inlet of the irrigation and drainage unit through a pipeline. The filtration unit includes a pumping pipe connected in series, a primary filtration section and a secondary filtration section. The primary filtration section includes two filtration mechanisms connected in parallel. The secondary filtration section is connected in series with the irrigation and drainage unit through a pipeline.

[0005] The primary filtration unit includes a basket filter A and a valve A connected by a rigid pipe. The inlet end of the basket filter A is connected to the pumping pipe via a tee A, and the outlet end of the valve A is connected to the secondary filtration unit via a tee B.

[0006] The secondary filtration unit includes a basket filter B. The inlet of the basket filter B is connected to the primary filtration unit via a tee B and a rigid pipe, and the outlet is connected to the irrigation and drainage unit.

[0007] The irrigation and drainage unit includes an irrigation and drainage pump and an inlet pipe. The secondary filtration unit is connected to the inlet of the irrigation and drainage pump through a pipeline. The irrigation and drainage pump is connected to the upper end of the water storage tank through the inlet pipe.

[0008] The irrigation unit includes an irrigation pump, valve B, and an outlet pipe. The irrigation pump is connected to the water storage tank through a rigid pipe. Valve B is located at the outlet end of the irrigation pump, and the outlet pipe is located at the outlet end of valve B.

[0009] A mechanical impeller flow meter A is also installed on the pipe of the primary filtration section, and a mechanical impeller flow meter B is also installed on the pipe of the secondary filtration section.

[0010] A primary filter screen is installed at the inlet of the water pumping pipe, and the primary filter screen is fixed to the water pumping pipe by a clamp.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a small-scale farmland irrigation and drainage device with a filtration function. By setting a filtration unit including a primary filtration section and a secondary filtration section at the front end of the irrigation and drainage unit, the filtration unit filters impurities entering the pumping pipe, effectively preventing larger impurities such as weeds, branches, plastic bags, and mud, as well as smaller impurities such as duckweed, from being sucked into the irrigation and drainage unit. This effectively protects the irrigation and drainage pump and extends its service life. In addition, by setting the primary filtration section in the filtration unit as two parallel filtration mechanisms, the two filtration mechanisms can work alternately during irrigation and drainage. When one filtration mechanism needs cleaning, its valve is closed, and the valve of the other filtration mechanism is opened, ensuring continuous irrigation and drainage work and reducing the number of times the machine needs to be stopped to clean the filtration mechanisms during irrigation and drainage, thereby effectively improving irrigation and drainage efficiency.

[0012] The technical solution provided by this utility model can not only effectively filter larger impurities such as branches, plastic bags, weeds, and mud clods and smaller impurities such as duckweed during the irrigation and drainage process, but also ensure the continuous operation of irrigation and drainage work and improve irrigation and drainage efficiency, making it suitable for promotion and application in small-scale farmland.

[0015] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0016] like Figure 1 , Figure 2 As shown, this utility model provides a small farmland irrigation and drainage device with filtration function, which includes a mobile frame 1 with a set of wheels 17, a water storage tank 2, an irrigation and drainage unit, a filtration unit and an irrigation unit set on the mobile frame 1. The water outlet of the irrigation and drainage unit is connected to the water inlet of the water storage tank 2, and the irrigation unit is connected to the water outlet of the water storage tank 2. The three together constitute the basic body of the irrigation and drainage device.

[0017] In addition, a filtration unit is located at the front end of the irrigation and drainage unit and connected to the inlet of the unit via a pipeline. It filters the water pumped from the farmland, removing larger impurities such as branches, weeds, plastic bags, and mud, as well as smaller impurities such as duckweed, before reaching the irrigation and drainage unit. Specifically, in this embodiment, the filtration unit includes a pumping pipe 3 connected in series, a primary filtration section, and a secondary filtration section, used for primary and secondary filtration of the pumped farmland water. In this embodiment, to avoid frequent shutdowns for cleaning after the primary filtration section filters out a large number of impurities during the irrigation and drainage process, and to prevent pipe blockage and reduced irrigation and drainage efficiency, the primary filtration section includes two parallel filtration mechanisms. The secondary filtration section is connected in series with the irrigation and drainage unit via a pipeline.

[0018] Specifically, in this embodiment, the primary filtration unit includes a basket filter A4 and a valve A5 connected by a rigid pipe. The inlet of the basket filter A4 is connected to the pumping pipe 3 via a tee A6. In this embodiment, since the primary filtration unit is used to filter larger impurities such as branches, weeds, plastic bags, and mud, the mesh size of the filter basket in the basket filter A4 is preferably in the range of 4-10 mesh. Furthermore, the outlet of the valve A5 is connected to the secondary filtration unit via a tee B8.

[0019] During irrigation and drainage, one filtration mechanism is activated by opening its valve A5, while valve A5 in the other filtration mechanism is closed, making that mechanism a backup. When the basket filter A4 in operation needs cleaning due to excessive impurities, first open valve A5 in the backup filtration mechanism, then close valve A5 in the operating filtration mechanism, allowing the pumped farmland water to pass through the current backup filtration mechanism. Open the basket filter A4 that needs cleaning, remove the filter basket, and clean out the filtered impurities. After cleaning, return the filter basket to basket filter A4, and that filtration mechanism becomes a new backup, ready to be activated again when the other filtration mechanism needs cleaning. This cycle effectively reduces the problem of frequent shutdowns for cleaning caused by large amounts of impurities filtered in the primary filtration section, thus improving irrigation and drainage efficiency.

[0020] Furthermore, the secondary filtration section is used to filter smaller impurities such as duckweed. It mainly includes a basket filter B7. The inlet of the basket filter B7 is connected to the primary filtration section through a tee B8 and a rigid pipe, and the outlet is connected to the irrigation and drainage unit. The mesh size of the basket filter B7 is 10-20 mesh.

[0021] Furthermore, the irrigation and drainage unit includes an irrigation and drainage pump 9 and an inlet pipe 10. The outlet of the basket filter B7 is connected to the inlet of the irrigation and drainage pump 9 through a rigid pipe. The irrigation and drainage pump 9 is connected to the upper end of the water storage tank 2 through the inlet pipe 10, and pumps the pumped farmland water into the water storage tank 2 through the upper end of the water storage tank 2.

[0022] Furthermore, the irrigation unit in this embodiment includes an irrigation pump 11, a valve B12, and a water outlet pipe 13. The irrigation pump 11 is connected to the water storage tank 2 through a rigid pipe. The valve B12 is located at the water outlet end of the irrigation pump 11, and the water outlet pipe 13 is located at the water outlet end of the valve B12.

[0023] Furthermore, to facilitate observation of whether basket filters A4 and B7 require cleaning and to ensure irrigation and drainage efficiency, this embodiment also includes a mechanical impeller flow meter A14 on the pipeline of the primary filtration section and a mechanical impeller flow meter B15 on the pipeline of the secondary filtration section. Preferably, the mechanical impeller flow meter A14 is located between valve A5 and tee B8, and the mechanical impeller flow meter B15 is located between basket filter B7 and the drainage pump. The mechanical impeller flow meters A14 and B15 are selected as non-powered mechanical pointer types; in this embodiment, the LXS-100E rotary vane water meters from Shanghai Instrument Factory No. 9 are preferred.

[0024] Based on the primary and secondary filtration sections, in order to avoid cleaning the primary filtration section too frequently, in this embodiment, a primary filter screen 16 is provided at the inlet of the water pumping pipe 3. The primary filter screen 16 is fixed to the inlet of the water pumping pipe 3 by a clamp and is used to perform primary filtration on the pumped farmland water.
