Drip irrigation permeation irrigation device for agricultural planting

Abstract

The invention relates to an improvement in an agricultural planting irrigation system device, in particular to a drip irrigation permeation irrigation device for agricultural planting. A water inflow pipe is connected to a drip irrigation pipe, multiple drip irrigation branch pipes are connected to the drip irrigation pipe, the water inflow pipe is connected to the drip irrigation pipe, and a filtering device is arranged at the water inflow end of the water inflow pipe. Multiple branch pipe outlets are formed in the drip irrigation pipe, the branch pipe outlets are of columnar structures, external threads are arranged on the outer sides of the branch pipe outlets, through holes are formed in the centers of the branch pipe outlets, and the through holes are communicated with the drip irrigation pipe. By means of the mode that pressure valves are additionally arranged on water outlets of all the drip irrigation branch pipes, it is guaranteed that pressure at different points in the drip irrigation pipe reaches water flow pressure of the drip irrigation branch pipe. Due to the fact that drip irrigation water outlets are very small, in order to keep a water source of the water inflow pipe free of large-particle impurities, the filtering device is arranged on the water inflow pipe, when a filter net on the filtering device is blocked, a filter cover is directly screwed off to clean the filter net, and convenience and rapidness are achieved. The pressure of all the drip irrigation water outlets on a pipeline can be basically identical, it is guaranteed that the water outflow amount of each drip irrigation opening is identical, and the irrigation effect is guaranteed.

Description

technical field [0001] The invention relates to the improvement of an irrigation system device for agricultural planting, in particular to a drip irrigation and permeation irrigation device for agricultural planting. Background technique [0002] Drip irrigation uses plastic pipes to send water to the roots of crops through holes or drippers on capillaries with a diameter of about 1mm for local irrigation. It is currently the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Compared with sprinkler irrigation, drip irrigation has a higher effect of saving water and increasing production. At the same time, it can be combined with fertilization to more than double the fertilizer efficiency. It is suitable for irrigation of fruit trees, vegetables, commercial crops and greenhouses, and can also be used for irrigation of field crops in places where there is drought and water shortage. Its disadvantage is t...

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

[0003] After years of development, drip irrigation technology has been relatively mature, but there are still many problems in drip irrigation technology, especially because drip irrigation mostly uses long pipes to deliver water, the pressure difference at each point on the pipe is large, and the pressure near the water inlet is relatively high. If the distance is large, the pressure in the distance is small, resulting in a large gap in the pressure imbalance and water delivery.

Another big problem is that the water outlet is easy to be blocked, which will cause a lot of trouble
