A combined drip irrigation system for compound gardens

Abstract

The invention discloses a combined type drip irrigation system for a compound garden. A water outlet of a water storage pool is connected with a water inlet pipe of a water suction pump. A water outlet pipe of the water suction pump is connected with a water inlet of a filtering device through a connecting water pipe. A water outlet of the filtering device is connected with a trunk pipe of a flowdividing pipe. The water outlet end of each branch pipe of the flow dividing pipe is connected with a pressurizing pump. Each pressurizing pump is connected with a capillary pipe through a connectingelement. Due to the detachable design, the number of all the capillary pipes of the branch pipes is adjusted according to needs, the lengths of the branch pipes can be easily changed according to theneeds of all the branches to as to adapt to different drip irrigation schemes, and the drip irrigation effect is improved. Each branch pipe is provided with the corresponding pressurizing pump which is matched with a water pressure sensor at the tail end, and the water pressure in the capillary pipes on all the branch pipes can be independently observed and adjusted. Through simple operation, thedrip irrigation distance can be changed so as to conveniently adapt to the different drip irrigation schemes, and the drip irrigation effect can be easily improved.

Description

Technical field[0001]The invention relates to the field of energy-saving and environmental protection equipment, in particular to a combined drip irrigation system for compound gardens.Background technique[0002]Drip irrigation uses plastic pipes to send water to the roots of crops through orifices or drippers on a capillary with a diameter of about 10 mm for local irrigation. It is currently the most effective water-saving irrigation method in dry and water-deficient areas, and the water utilization rate can reach 95%. Drip irrigation has higher water-saving and yield-increasing effects than sprinkler irrigation, and can be combined with fertilization to more than double the fertilizer efficiency. It can be used for irrigation of fruit trees, vegetables, economic crops and greenhouses, and it can also be used for irrigation of field crops in drought and water shortage areas. The disadvantage is that the dripper is prone to scaling and clogging, so the water source should be strictly...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the dripper is easy to scale and block, so the water source should be strictly filtered

[0005] The existing capillary structure for drip irrigation is single, usually an integrated design, its length and drip irrigation spacing are fixed values, which cannot be changed, and cannot be adapted to various drip irrigation schemes according to actual needs, which is inconvenient in use
