Agricultural water-saving drip irrigation head

Abstract

The invention relates to an agricultural water-saving drip irrigation head, which comprises a shell, an upper pressure pipe and a lower pressure pipe, wherein the upper and lower pressure pipes are arranged in the shell. The agricultural water-saving drip irrigation head is further provided with a spring cap head extruded between the upper and lower pressure pipes, wherein the upper pressure pipe is connected with a water source; the upper and lower ends of the spring cap head are pressed against the nearest ports of the upper and lower pressure pipes respectively. According to the agricultural water-saving drip irrigation head, the spring cap head forms extrusion contact with the upper and lower pressure pipes to form an incompletely-sealed structure between the upper and lower pressure pipes, so that water can seep under the condition of natural water pressure; by virtue of a threaded connecting structure, extrusion pressure between the spring cap head and the upper pressure pipe is conveniently regulated, and seepage flow on frosted surfaces can also be regulated; the lower pressure pipe contacts with the shell through a spring to form second group of spring pressure except the spring cap head, and acts together with the spring in the spring cap head to ensure that sealing effects of the frosted surfaces of an upper cap and a lower cap on openings of a water flow passage can be regulated, so that the seepage flow can be regulated.

Description

technical field [0001] The invention relates to an agricultural equipment, in particular to an agricultural water-saving drip irrigation head for irrigation. Background technique [0002] Drip irrigation is the use of plastic pipes to send water to the roots of crops through holes or drippers on capillaries with a diameter of about 10 mm 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 that the dripper is easy to scale and block, so t...

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] For larger plants and drip irrigation in relatively concentrated locations, it is necessary to adjust the amount of drip irrigation one by one, and the amount of drip water adjusted anytime and anywhere; at the same time, in the absence of tap water equipment, natural water pressure (gravity) such as bottled water For drip irrigation, existing equipment won't work
