Description

Technical Field

[0001] The present invention relates to the technical field of irrigation devices, in particular to an irrigation device for tomato planting. Background Art

[0002] In the field of modern agricultural production, soilless tomato cultivation technology has become an important development direction for improving tomato yield and quality due to its advantages such as not being restricted by soil conditions and facilitating precise control of the growth environment. Drip irrigation technology is a commonly used irrigation method in soilless tomato cultivation. Through a low-pressure pipe system and drippers, water and nutrients are dripped evenly and slowly into the vicinity of the tomato root system at a small flow rate. It has significant advantages such as saving water and fertilizer, reducing diseases and pests, and effectively improving the efficiency and economic benefits of tomato cultivation. However, the drip irrigation devices currently used in soilless tomato cultivation have obvious technical bottlenecks. Existing drip irrigation devices usually only have a single liquid introduction function, that is, they can only supply single-component water and fertilizer to tomato plants, such as only ordinary irrigation water or a single-ratio nutrient solution. This makes it difficult to supply water and nutrients to tomatoes at the same time during planting. If multiple sets of low-pressure pipes are added, not only will the cost of use increase, but the multiple sets of low-pressure pipes will also occupy a larger space, affecting the growth environment of tomatoes. Summary of the Invention

[0003] Based on this, the purpose of the present invention is to provide an irrigation device for tomato planting to solve the technical problems in the above-mentioned background technology.

[0013] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0014] The following describes an embodiment of the present invention based on its overall structure.

[0015] Example 1 like Figure 1-9 As shown, this embodiment focuses on an irrigation device for tomato planting. Its structural design focuses on dual-medium synchronous delivery, precise diversion, and flexible drip irrigation. It is mainly composed of a two-way pipe mechanism 1, a joint mechanism 2, and a drip irrigation mechanism 3. The dual-circulation pipe 101 uses a 50mm diameter PVC-U double-wall corrugated pipe with a compressive strength of ≥0.6MPa. The length can be flexibly cut according to the planting area, such as 100m. The pipe is divided into two independent flow chambers 103 by a separator 102. The cross-sectional area of ​​each chamber is 12.5cm², which are used to transport irrigation water and nutrient solution respectively. The two sets of liquid inlet pipes are respectively connected to the water inlet end of the dual-circulation pipe 101, and are connected to the external water fertilizer tank with a volume of 500L through quick-connect connectors. The compartment design supports the simultaneous delivery of two different liquid media; The joint connecting pipe 201 is made of ABS engineering plastic, with an external threaded ring 4 on the side and a limiting ring 207 fixed at the bottom end of the inner wall. The limiting ring 207 is fixed to the bottom end of the inner wall of the joint connecting pipe 201, and the limiting groove 208 provided on the diverter plate 202 and the limiting ring 207 abut against each other for limiting position. The diverter baffle is integrally injection-molded and consists of a diverter plate 202, a diverter block 203, a snap-fit ​​sealing groove 204, a top plate 205, and a positioning plate 206. The snap-fit ​​sealing groove 204 at the bottom precisely snaps into place with the top of the separator 102. The two sets of diverter blocks 203 are arranged at a 45° angle, dividing the interior of the joint connecting pipe 201 into two independent cavities, which are respectively connected to the two sets of flow cavities 103 of the dual-flow pipe 101; The internal thread of the fastening cap 213 matches the external thread ring 4. The internal movable cavity is movably connected to the mating head 215. The bottom is elastically connected to the bottom ring 212 through the spring frame 211. When tightened, it can generate an axial compression force of 50N to ensure sealing. The two sets of connecting pipes vertically penetrate the joint connecting pipe 201 and adopt a barbed interface to quickly connect with the drip irrigation pipe 301. The flow rate is controlled at 5-10L / h. The drip irrigation pipe 301 uses a PE hose with an inner diameter of 10mm, and has five groups of nozzles 302 distributed on the surface. The nozzles are pressure-compensated with a working pressure of 0.05-0.3MPa, a drip flow rate of 2L / h, and can be rotated 360° to adjust the spraying angle. The front end of the drip irrigation pipe 301 is a corrugated structure that supports manual bending and shaping to adapt to the root distribution of tomato plants at different growth stages, such as close to the substrate surface during the seedling stage and raised to the base of the stem during the flowering stage; Pipeline laying and installation According to the spacing between tomato planting rows, use a special hole opener to open each installation hole on the dual-circulation pipe 101. Apply PVC special glue to the joint connecting pipe 201 and insert it into the installation hole. Ensure that the joint connecting pipe 201 fits tightly against the inner wall of the dual-circulation pipe 101. Let it stand for 2 hours to allow the glue to solidify. Install the diverter baffle: Align the sealing groove 204 at the bottom of the diverter plate 202 with the separator 102 and insert the joint connecting pipe 201 until the limiting groove 208 abuts the limiting ring 207 and the positioning plate 206 is vertically upward; Fastening and sealing Insert the bottom ring 212 into the edge of the top plate 205, insert the bottom of the spring frame 211 into the groove of the bottom ring 212, screw on the fastening cap 213, push the positioning and pressing frame 209 down through the mating head 215, and engage the positioning groove 210 with the positioning plate 206 until the spring frame 211 is passively compressed to generate a sealing force. Connect the connecting pipe 214 and the drip irrigation pipe 301, and ensure that the barb interface is fully inserted. The seal is completed when you hear a "click" sound; Water and fertilizer delivery and drip irrigation Open the external water and fertilizer tank valve, and the nutrient solution A and the clean water B enter the two flow chambers 103 of the dual flow pipe 101 through the liquid inlet pipe 104 respectively, with the flow rate controlled at 0.5m / s; After being diverted by the diversion baffle, the liquid enters the drip irrigation pipe 301 through the connecting pipe 214 and is evenly dripped by the nozzle 302 to the roots of the tomato plants. For example, the left flow chamber 103 delivers nutrient solution with an EC value of 2.0, while the right side delivers clean water, realizing a "water and fertilizer alternating" irrigation mode, which promotes nutrient absorption by the tomato roots. The drip irrigation frequency is adjusted according to the tomato growth cycle. Drip irrigation is carried out twice a day during the seedling stage, each time for 30 minutes, and three times a day during the flowering stage, each time for 20 minutes. The flow rate of each group of drip irrigation pipes 301 is monitored in real time by a flow sensor with an accuracy of ±2%, ensuring a uniformity error of ≤5%; Maintenance and Adjustment Check the looseness of the fastening cap 213 weekly, dismantle the drip irrigation pipe 301 monthly, and flush the nozzle 302 with 3% citric acid solution to prevent clogging by calcium and magnesium ions; After the tomato plants are hung, the angle of the corrugated section of the drip irrigation pipe 301 is manually adjusted so that the nozzle 302 is aimed at the root area to prevent the liquid from being sprayed onto the leaves and causing diseases.

[0016] The working principle of the present invention is as follows: when in use, a double-pass pipe mechanism 1 is used as the main low-pressure pipe for drip irrigation, wherein a separator 102 integrally formed therewith is provided inside the double-pass pipe 101, so that the interior of the double-pass pipe 101 is divided into two groups of flow chambers 103. Then, under the action of two groups of liquid inlet pipes 104, water and solutions such as water-fertilizer nutrients can be respectively introduced into the two groups of flow chambers 103. In other words, the double-pass pipe mechanism 1 can simultaneously transport two groups of media in one pipe, effectively ensuring high efficiency during tomato planting, while reducing the cost of using two independent pipes to transport two groups of media. The dual-circulation pipe 101 is cut to a suitable length according to the actual situation, and a drilling device is used to drill holes in the dual-circulation pipe 101 according to the distance between each two groups of tomato plants, so that the joint mechanism 2 and the dual-circulation pipe 101 can be connected to each other. Specifically, after a through hole is formed in the dual-circulation pipe 101, a sealant is applied to the outside of the joint connecting pipe 201 and the joint connecting pipe 201 is inserted into the hole. At this time, the engaging sealing groove 204 formed on the bottom of the diverter plate 202 inside the joint connecting pipe 201 is engaged with the outside of the separator 102. At the same time, under the action of the two diagonally arranged diverter blocks 203, the two sets of flow cavities 103 are connected to the two sets of cavities inside the joint connecting pipe 201 respectively. At this time, the bottom ring 212 is installed to the top of the top plate 205. Before the fastening cap 213 is screwed to the joint connecting pipe 201 through the external threaded ring 4, the positioning groove 210 at the bottom of the positioning and pressing frame 209 rotatably connected to the fastening cap 213 is first engaged with the positioning plate 206. When the fastening cap 213 is rotated, the rotation of the fastening cap 213 will not drive the positioning and pressing frame 209 to rotate. At the same time, the fastening cap 213 has an active cavity that cooperates with the mating head 215. When the fastening cap 213 is tightened, the positioning groove 210 is tightly fitted with the top of the positioning plate 206. As the fastening cap 213 descends during rotation, the bottom of the spring frame 211 is located inside the bottom ring 212, so that the spring frame 211 is passively compressed. The compressed force generated by the spring frame 211 is transmitted to the top plate 205 through the bottom ring 212. As the top plate 205 transmits the force to the diverter plate 202 and the two groups of diverter blocks 203, the engaging sealing groove 204 is more tightly connected and sealed with the separator 102, thereby ensuring that the liquid media inside the two groups of flow chambers 103 will not leak or mix, so that the two groups of liquid media can be transported simultaneously for drip irrigation operation; Two groups of connecting pipes 214 are provided on both sides of the joint connecting pipe 201, wherein the two groups of connecting pipes 214 are respectively connected to the drip irrigation pipes 301 of the drip irrigation mechanism 3, wherein a plurality of nozzles 302 are distributed on the drip irrigation pipes 301, and the tomato plants can be drip irrigated through the nozzles 302. The drip irrigation pipes 301 adopt a corrugated pipe structure, and the staff can manually adjust the drip irrigation position of the drip irrigation pipes 301 according to actual conditions, so that the nozzles 302 can better perform drip irrigation operations on the tomato plants.

The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention.
