U-shaped modular extensible multifunctional spraying and dripping irrigation system

Abstract

The invention provides a U-shaped modular extensible multifunctional spraying and dripping irrigation system, and belongs to the field of irrigation of farmland water conservancy, garden economic crops and greenhouse crops. The system comprises a power machine pump, a suction inlet filter, a spraying irrigation fertilizer application device, a head drying pipe, a spraying irrigation control valve,a dripping irrigation control valve, a spraying irrigation branch pipe, a sprayer and auxiliary device, a dripping irrigation pressure reduction valve, a water power balance branch pipe, a dripping irrigation fertilizer application device, a dripping irrigation filter, a micro-dripping irrigation branch pipe, a micro-dripping irrigation module, a capillary tail pressure meter and a drainage ditch. According to the system, spraying irrigation and dripping irrigation can be simultaneously and independently implemented, the system has irrigation, fertilization and drainage functions, water powerdesign is reasonable, investment cost can be controlled, movable and fixed modes can be adjusted, irrigation areas are easily widened, and the system is high in adaptability and utilization rate.

Description

technical field [0001] The invention relates to irrigation fields such as farmland water conservancy, garden economic crops, greenhouse crops, etc., and particularly relates to a U-shaped modular expandable multifunctional spray and drip irrigation system. Background technique [0002] my country is a large agricultural country, and irrigation technology has become an important part of agricultural modernization, playing an important role in increasing agricultural production and income. But at the same time, the terrain conditions for crop planting are complex and there are many kinds of crops. In order to improve the utilization rate of cultivated land, both in the north and the south, there are situations such as intercropping of crops in the same irrigation season, split cropping of crops in the same irrigated plot, and rotation of different crops in different irrigation seasons. Differences in different species, differences between tall and short stems, and differences...

Problems solved by technology

Invention patent 200610049562.0 discloses a double-low spray drip irrigation method, which involves four sprinkler irrigation or drip irrigation methods, but it does not mention the simultaneous irrigation of sprinkler irrigation and drip irrigation, which is difficult to meet the needs of short and tall crops such as "peanut + corn" Drip irrigation for intercropping is required, and the fertilization function is not considered

Invention patent 201410083292.X discloses a light and small dual-purpose device for spraying and drip irrigation for agricultural planting. It uses negative pressure fertilization at the inlet of the water pump, and uses a self-priming pump-based dual-working pump for spraying and drip irrigation. However, this patent only applies to the first part of the system. The composition is introduced, but it does not involve the corresponding situation of the piping arrangement of the system and the planting of field crops. The same deficiency exists in patents 201310314102.6 and 201310515933.X

But the disadvantage of this arrangement is that the working pressure of the emitters for sprinkler irrigation and drip irrigation is quite different, generally around 0.15MPa ~ 0.25MPa

The method of sequentially arranging the sprinkler irrigation branch pipe 7 and the drip irrigation belt on the same main pipe will make it difficult to balance the hydraulic state of each branch pipe, or the pressure loss of the regulating valve at the entrance of the drip irrigation belt is too large, resulting in energy waste; two irrigation modes: sprinkler irrigation and drip irrigation There may be differences in parameters such as water demand, fertilization amount, irrigation frequency, and fertilization frequency. The system composition method of alternate arrangement of sprinkler irrigation and drip irrigation branches will bring inconvenience to the unified adjustment of irrigation water amount and fertilization amount under the two irrigation methods. ; The system uses a large amount of pipelines and requires a large investment; the control area of ​​a power machine pump 1 is limited, and it is difficult to expand the area

Moreover, the above-mentioned systems all consider the field drainage problem, which is not conducive to resource utilization and environmental protection
