Abstract
Description
Technical Field
[0001] This utility model belongs to the field of facility agriculture technology, specifically a water and fertilizer integrated irrigation system suitable for facility agriculture. Background Technology
[0002] In facility agriculture (such as greenhouses and multi-span greenhouses), traditional irrigation and fertilization often employ manual, staged operations. Irrigation relies on extensive methods like furrow and bed irrigation, resulting in high water evaporation rates (up to 30%-50%) and soil compaction. Fertilization is done manually by spreading or flushing, leading to insufficient fertilizer dissolution and uneven distribution, with nitrogen, phosphorus, and potassium nutrient losses exceeding 40%, resulting in high input costs (2000-5000 yuan per acre per year). Furthermore, manual operations are limited by experience and labor intensity, making it difficult to precisely control water and fertilizer amounts according to different crop growth stages (such as seedling, flowering, and fruit expansion stages). This often leads to problems such as root hypoxia, excessive vegetative growth, and fertilizer damage, affecting crop quality (e.g., a 2-3°Brix decrease in fruit sugar content) and yield (a 10%-20% reduction).
[0003] As facility agriculture develops towards large-scale and intensive operations (e.g., a single greenhouse exceeding 100,000 square meters), traditional manual methods can no longer meet the demands for efficient management. On the one hand, large-scale planting requires irrigation systems with zoned control capabilities (e.g., different crop zones require independent water and fertilizer solutions), while traditional pipe networks struggle to achieve precise zoning. On the other hand, high-end crops (e.g., hydroponic strawberries and hydroponically grown lettuce) place stringent demands on the root zone environment (soil moisture 80%-85%, EC value 1.2-1.8 mS / cm), and the lag in manual monitoring (intervals of 4-6 hours) easily leads to untimely regulation. Simultaneously, the problem of water scarcity is becoming increasingly prominent (agricultural water use accounts for over 60% of my country's total water consumption, but the effective utilization rate is only 40%). The national "Water Conservation Action" requires the effective utilization coefficient of agricultural irrigation water to be increased to above 0.58, forcing the industry to urgently require integrated water- and fertilizer-saving solutions.
[0004] Therefore, this utility model provides an integrated water and fertilizer irrigation system suitable for facility agriculture. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, a water and fertilizer integrated irrigation system suitable for facility agriculture is proposed.

[0007] Preferably, the material extraction mechanism includes a support ring frame, a fertilizer pump, and a delivery pipe. Two sets of support ring frames are provided, each set sleeved at both ends of the surface of the second water pipe.

The input end of the fertilizer pump is fixedly installed on the delivery pipe. In this design, the support ring frame provides support for the delivery pipe, ensuring that the pipe does not become unstable during material delivery. The combined use of the fertilizer pump and the delivery pipe allows the fertilizer inside the storage tank to be extracted and transported to the interior of the second water pipe, where it mixes with water.
[0008] Preferably, the storage tanks are provided in three sets, and the three sets of storage tanks are fixedly installed on the top of the conveying pipe.

[0010] Preferably, the agitation assembly includes agitation plates and through holes. Several groups of agitation plates are provided, and the several groups of agitation plates are fixedly installed in a ring on the surface of the rotating shaft. The surface of the agitation plates is provided with through holes. In this scheme, the agitation plates can rotate by the drive of the rotating shaft to agitate the water flow inside the second water pipe so that it can be fully mixed with fertilizer, thereby improving irrigation efficiency. The opening of through holes can improve the stirring efficiency of the agitation plates.
[0011] Preferably, the irrigation assembly includes an air valve and an irrigation pipe. The air valve is fixedly installed on one side of the surface of the second water pipe, and the irrigation pipe is fixedly installed at the end of the second water pipe away from the first water pipe. In this design, the air valve can promptly deliver air into the interior of the second water pipe after the water source inside the second water pipe is discharged, so that the air pressure inside the second water pipe can be kept consistent with the outside, preventing the occurrence of internal and external pressure differences. The irrigation pipe can atomize the mixed water source and spray it out in all directions, increasing the irrigation area.

The connection port 41 is fixedly installed at the end of the first water pipe 2 away from the second water pipe 3, and the top of the surface of the first water pipe 2 is fixedly installed with the water pump 42. The material extraction mechanism 5 includes a support ring frame 51, a fertilizer pump 52, and a conveying pipe 53. Two sets of support ring frames 51 are provided, and the two sets of support ring frames 51 are sleeved at both ends of the surface of the second water pipe 3. The fertilizer pump 52 is fixedly installed on the top of the surface of the second water pipe 3. The output end of 2 is connected to the second water pipe 3. The input end of the top of the fertilizer pump 52 is fixedly installed with the conveying pipe 53. Three sets of storage tanks 60 are provided, and the three sets of storage tanks 60 are fixedly installed on the top of the conveying pipe 53. The rotating mechanism 7 includes a fixed support rod 71, a turbine blade 72 and a rotating shaft 73. Two sets of fixed support rods 71 are provided. The two sets of fixed support rods 71 are fixedly installed on both sides of the inner wall of the second water pipe 3. The side of the fixed support rods 71 that is close to each other is rotatably installed with the turbine blade 72. The side of the turbine blade 72 that is away from the fixed support rod 71 is fixedly installed with the rotating shaft 73. The stirring component 8 includes a stirring plate 81 and a through hole 82. Several sets of stirring plates 81 are provided. Several sets of stirring plates 81 are fixedly installed in a ring on the surface of the rotating shaft 73. The surface of the stirring plate 81 is provided with a through hole 82. The irrigation component 9 includes an air valve 91 and an irrigation pipe 92. The air valve 91 is fixedly installed on one side of the surface of the second water pipe 3. The irrigation pipe 92 is fixedly installed at the end of the second water pipe 3 away from the first water pipe 2.
[0025] like Figures 1 to 4As shown, the connection port 41 allows users to quickly connect the external water pipe to the first water pipe 2, ensuring the speed of installation during irrigation. The water pump 42 can draw water into the first water pipe 2 to supply water to the irrigation component 9. The support ring 51 provides support for the conveying pipe 53 to ensure that the conveying pipe 53 does not become unstable during material conveying. The fertilizer pump 52, in conjunction with the conveying pipe 53, can extract fertilizer from the storage tank 60 and deliver it to the second water pipe 3, allowing it to mix with water.

The opening of the through hole 82 can improve the stirring efficiency of the stirring plate 81. The air valve 91 can promptly deliver air into the second water pipe 3 after the water source inside the second water pipe 3 is discharged, so that the air pressure inside the second water pipe 3 can be kept consistent with the outside, preventing the occurrence of internal and external pressure differences. The irrigation pipe 92 can atomize the mixed water source and spray it out in all directions to increase the irrigation area.
[0026] Working principle: During operation, the support leg 1 is first installed in the usage position. Then, the user connects to the water source through the connection port 41 and starts the water pump 42 to draw water into the first water pipe 2. The water then flows through the first water pipe 2 into the second water pipe 3. When the water enters the second water pipe 3 and passes through the turbine blades 72, the turbine blades 72 rotate due to the water flow. The rotation of the turbine blades 72 drives the rotating shaft 73 and the agitator plate 81 to rotate. The water continues to flow until it flows into the irrigation pipe 92. When integrated water and fertilizer irrigation is required, the user needs to pour various fertilizers into the three sets of storage tanks 60 in sequence. Then, the fertilizer pump 52 is started to draw the fertilizer from the three sets of storage tanks 60 into the second water pipe 3 through the delivery pipe 53. After the fertilizer enters the second water pipe 3, it will be fully mixed with the water due to the agitation of the agitator plate 81 and sprayed out through the irrigation pipe 92, thus completing the irrigation.
