Farmland sprinkler irrigation system with automatic fertilization function

Abstract

The invention relates to a farmland sprinkler irrigation system with an automatic fertilization function. The system comprises a water source used for supplying irrigation water, and further comprisesa power hub, wherein the power hub comprises a water pump, an intelligent water and fertilizer control integrated machine, a filtering device, a metering device and pipe fittings; the water source isconnected with the water pump through the pipe fitting, the water pump is connected with the filtering device through the pipe fitting, and the intelligent water and fertilizer control integrated machine is connected to the pipe fitting between the water pump and the filtering device; the metering device comprises a pressure gauge arranged at the pipe fittings at a water inlet position and wateroutlet position of the filtering device; the intelligent water and fertilizer control integrated machine is internally provided with an automatic metering device and a nutrient storage device, the putting speed of nutrients is calculated according to the water flow rate value detected by the metering device and a predetermined water and fertilizer concentration, the nutrients of the putting speedare taken from the nutrient storage device and mixed with water flow of the pipefittings to prepare water-fertilizer of a predetermined concentration, and the water-fertilizer is conveyed to a sprinkler irrigation terminal.

Description

technical field [0001] The invention relates to the technical field of crop irrigation, in particular to a farmland sprinkler irrigation system capable of automatic fertilization. Background technique [0002] At this stage, the sprinkler irrigation systems used in my country generally include traditional fixed sprinkler irrigation systems, buried telescopic sprinkler irrigation systems, winch type sprinkler irrigation system, central pivot type sprinkler irrigation system, translational sprinkler irrigation system, micro sprinkler With sprinkler system. The working pressure of the traditional fixed sprinkler irrigation system is above 0.3MPa, the working pressure is high, the energy consumption is high, and it is not easy to install and disassemble quickly; the working pressure of the buried telescopic sprinkler irrigation system is above 0.3MPa, the working pressure is relatively high , high energy consumption, although there is no need to reserve irrigation channels, whic...

AI Technical Summary

Problems solved by technology

The working pressure of the traditional fixed sprinkler irrigation system is above 0.3MPa, the working pressure is high, the energy consumption is high, and it is not easy to install and disassemble quickly; the working pressure of the buried telescopic sprinkler irrigation system is above 0.3MPa, the working pressure is relatively high , high energy consumption, although there is no need to reserve irrigation channels, which can save cultivated land, but the system is not stable at this stage; the working pressure of the winch type sprinkler irrigation system is above 0.3MPa, the working pressure is high, the energy consumption is high, and it needs Tractors and other traction machinery; the central pivot type sprinkler irrigation system is suitable for large plots of cultivated land (more than 5...
