Improved metal sprinkler gun

Abstract

The invention provides an improved metal sprinkler gun. A lug and a concave pit are arranged at reversing and positioning parts so that the metal sprinkler gun is not easy to loosen; a thrust bearing gasket and a function wave gasket which are provided with self-centering inclined planes are not easy to incline and a blocked portion is reduced; a ringed spring (m19b) which is provided with a toggle spring can be used for enabling triggering conversion to be more reliable; a parabola water baffle can be used for enabling the water to be more ideally scattered; a metal water outlet (15) which is provided with a parabola channel (15b) and a reinforced rib plate (15a) can be used for increasing the spraying coagulation power and smoothness; a handle part of a water thrashing target (m8) is provided with a fast-slow adjustment screw (m22) and a fastening screw cap (m23); when the length needs to be adjusted or a self counter weight is changed or suspended heavy objects including eardrops or threading lines are matched, the distance and the weight can be changed and a rotary inertia moment can be changed, so that a method capable of influencing and regulating the fast and slow swinging of the sprinkler gun is provided; according to the invention, the fast and slow swinging of the sprinkler gun can be regulated from no fast and slow regulations and a plurality of comprehensive developments are improved, so that the major contribution on the sprinkler gun can be made.

Description

technical field [0001] The invention relates to a metal sprinkler head used for gardening, horticultural and agricultural liquid sprinklers, especially provides a method for improving the adjustable speed and reversing positioning of the water target for the sprinkler head, which belongs to the sprinkler head technology in the spraying device field. Background technique [0002] The rotating sprinkler head of the liquid sprinkler for watering gardens, horticulture and agriculture has been widely used in the way selected by people's preferences for 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 rotating sprinkler head, is the key equipment of the sprinkler irr...

AI Technical Summary

Problems solved by technology

[0004] 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.
