Drip irrigation type moisturizing greenhouse irrigation system

Abstract

The invention relates to the technical field of greenhouse planting equipment, in particular to a drip irrigation type moisturizing greenhouse irrigation system. The system comprises an irrigation system body, and the irrigation system body comprises a water tank, a main flow pipeline, flow distributing pipelines and drip irrigation nozzles. The system has the beneficial effects that a water tankwith a filter screen and a partition plate is arranged, therefore, water flow is filtered through the filter screen, impurities in the water flow are reduced, blockage is avoided, water flow impact isbuffered through the partition plate, the water flow pressurized by a water pump stably flows into a pipeline in an overflow manner, and impact of water flow movement on the pipeline is reduced; andby arranging an overflow plate, dropping of dropping water is buffered, meanwhile, water drops are prevented from being gradually gathered into drops at the positions of the nozzles through flow guideneedles, and therefore the contact time of the water drops and the opening positions of the nozzles is shortened, in cooperation with flow distribution grooves and water storage grooves in a bottom plate, uniform flow distribution in three directions is achieved, the water drops can be prevented from directly impacting the ground to cause grooves, and the purpose of uniformly guiding drip irrigation is achieved.

Description

technical field [0001] The invention relates to the technical field of greenhouse planting equipment, in particular to a drip irrigation type moisture-retaining greenhouse irrigation system. Background technique [0002] Drip irrigation is to use plastic pipes to drop water evenly and slowly through the small holes on the lower head or the drip irrigation pipe belt, and drip it on the root system of the crops for local irrigation. The working pressure and the flow rate of the dripper are small. Drip irrigation is a kind of water It is an economical, labor-saving and labor-saving irrigation method, especially suitable for use in mountainous areas and sandy lands where water is scarce, and the utilization rate can reach 90%. [0003] However, during the drip irrigation process, the position of the dripper is prone to fouling or clogging. The reason for the clogging is that the water source contains a large amount of suspended solids or impurities. It is easy to cause the vibr...

Problems solved by technology

[0003] However, during the drip irrigation process, the position of the dripper is prone to fouling or clogging. The reason for the clogging is that the water source contains a large amount of suspended solids or impurities. It is easy to cause the vibration of the pipeline, which will cause a gap in the connection of the diversion water outlet to cause leakage. Long-term drip irrigation on the crop planting ground is prone to pits, and the water flow gathers in the pits, which is not conducive to the water absorption of the crops.

[0004] To this end, a drip irrigation moisturizing greenhouse irrigation system is provided to solve the problems of dripper clogging, connection leakage and drip accumulation
