Improved plastic sprinkling irrigation head

Abstract

The invention relates to a plastic sprinkling irrigation head serving as a key device of an improved sprinkling irrigation system, and provides a method for improving mixture of a water fetching target, a method for relieving friction with a function wave clutch disc, a method for reversing and positioning with a circumferential dense gear and a method for adopting a spray core of a parabolic channel to try to solve the long-standing big and difficult problems that a plastic water fetching target of an existing plastic sprinkling irrigation head is easy to break, a reversing and positioning block is easy to loose with the passing of time, friction needs to be relieved by rotating a mandrel, and sealing is difficult. The invention further provides a method for changing the swing speed cycle of the sprinkling irrigation head by adjusting inertia moment by hanging an eardrop (21) on an aesthetic eardrop hole (8a) arranged on a handle of the water fetching target (8), the quality and the grade of the sprinkling irrigation head are improved by taking various improvement measures, and probably, the arrangement of the eardrop (21) hung on the water fetching target (8) of the sprinkling irrigation head is substantially the method for adjusting and changing the swing speed cycle of the sprinkling irrigation head according to the principle of the inertia moment so as to make an important contribution to sprinkling irrigation.

Description

technical field [0001] The invention relates to a plastic sprinkler head used for gardening, horticulture and agricultural plastic sprinklers, in particular, it provides methods for improving the water target mixture, reducing friction and reversing positioning, and belongs to the sprinkler head in the spraying device technology field. Background technique [0002] The plastic sprinkler heads of plastic sprinklers used in gardens, horticulture and agriculture are widely used in the way people choose to carry out farmland, forestry nurseries, plastic greenhouses, urban roadsides, lawns, flower beds, greening, etc. Operating sprinkler irrigation. One of the major problems in the world is the shortage of fresh water resources, and water-saving sprinkler irrigation has gradually become an important means of planting crops and garden flowers. The sprinkler head, especially the plastic sprinkler head, is the key equipment of the sprinkler irrigation system, and its performance d...

Problems solved by technology

[0003] The purpose of the present invention is to improve the key equipment of the sprinkler irrigation system, provide improved water target mixture and reduce friction, reversing positioning and sprayer methods, improve the effect of sprinkling irrigation, and try to solve the problem of the plastic water target of the existing plastic sprinkler head Several places are easy to break when the pressure is high, and the adjustment and positioning of the reversing positioning block are easy to loose after a long period of time. The friction between the rotary mandrel and the hexagonal head must be reduced to ensure reliable reversing and to meet the sealing between the two In order to prevent the long-standing problem of leakage; to improve the uniform quality of the sprayed matter, to overcome the lack of working conditions caused by the various mechanisms of the sprinkler heads in the prior art, and to invent several different types of sprinkler heads at the same time.
