Water-fertilizer-integrated and liftable micro-irrigation system

Abstract

The invention discloses a water-fertilizer-integrated and liftable micro-irrigation system. The water-fertilizer-integrated and liftable micro-irrigation system comprises a field head device, a pipeline network, a lifting device and micro-irrigation devices and is characterized in that the field head device comprises a water supply unit and a fertilizer filling unit which are connected; the pipeline network comprises a main water pipe, branch pipes connected with the main pipe and capillary pipes fixed on the branch pipes, the main pipe is communicated with the field head device, and the micro-irrigation devices are fixed at the tail ends of the capillary pipes; the lifting device comprises support rods and lifting mechanisms, the branch water pipes are arranged on the support rods, and each lifting mechanism comprises a fixing shaft, a drive device and winches fixed on the fixing shaft; each micro-irrigation device comprises a micro-nozzle and a bottom support and a retaining plate which are arranged at the bottom of the micro-nozzle. By the structure, the water-fertilizer-integrated and liftable micro-irrigation system has the advantages that irrigation heights can be regulated precisely, and the water-fertilizer-integrated and liftable micro-irrigation system is wide in height adjusting range, capable of increasing water and fertilizer utilization rate, wide in application range and wide in irrigation range.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation equipment, in particular to a liftable micro-irrigation system integrating water and fertilizer. Background technique [0002] Agriculture is a large user of water. In recent years, agricultural water consumption has accounted for about 62% of the total economic and social water consumption, and in some areas as high as 90%. Therefore, the distance from the ground needs to be adjusted to meet the needs of fruit and vegetable irrigation and leaf vegetable irrigation respectively. Most of the existing liftable irrigation devices use telescopic rods or hydraulic mechanisms to adjust the height. The adjustment range is small and the height adjustment accuracy is poor. , and the cost is high, which is not conducive to the use and promotion of irrigation devices. The existing irrigators are only suitable for irrigation on the membrane, which limits the scope of application of the micro-s...

[0002] Agriculture is a large user of water. In recent years, agricultural water consumption accounts for about 62% of the total economic and social water consumption, and as high as 90% in some areas. The efficiency of agricultural water use is not high, and with different crops, the same crops will need different water consumption in different periods. Therefore, the distance from the ground needs to be adjusted to meet the needs of fruit and vegetable irrigation and leaf vegetable irrigation respectively. Most of the existing liftable irrigation devices use telescopic rods or hydraulic mechanisms to adjust the height. The adjustment range is small and the height adjustment accuracy is poor. , and the cost is high, which is not conducive to the use and promotion of irrigation devices. The existing irrigators are only suitable for irrigation on the membrane, which limits the scope of application of the micro-spray. At the same time, when the micro-spray is too close to the ground, it is prone to clogging The case of micro sprinklers
