Agricultural dropper

Abstract

The invention relates to a drip irrigation head for agriculture, comprising: a housing, an upper pressure tube and a lower pressure tube installed inside the housing, and a spring cap squeezed between the upper pressure tube and the lower pressure tube , the upper pressure tube is connected to a water source, and the upper end and the lower end of the spring cap are against the nearest ports of the upper pressure tube and the lower pressure tube respectively. The spring cap head forms an incomplete sealing structure between the upper pressure tube and the lower pressure tube through the squeeze contact between the upper pressure tube and the lower pressure tube, so that the water can also seep out under the condition of natural water pressure ;The upper pressure tube can easily adjust the extrusion force between the spring cap head and the pressure tube through the threaded connection structure, and can also adjust the seepage amount of the frosted surface; the lower pressure tube contacts the shell through the spring, which forms the first Two sets of spring pressure, which work together with the spring in the spring cap head to ensure that the sealing effect of the frosted surface of the upper cap and the lower cap on the water flow channel opening can be adjusted, so that the seepage volume can be adjusted.

Description

technical field

[0001] The invention relates to an agricultural equipment, in particular to an agricultural 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 10mm for local irrigation. It is currently the most effective water-saving irrigation method in arid and water-scarce areas, and the water utilization rate can reach 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 the water sou...
