Description
Technical field: the utility model belongs to field of plant protection machine, especially a kind of shower nozzle of spraying machine.
Background technology: the spraying operation of spraying machine is that liquid to be delivered to jet pipe under spray pump effect be vaporific ejection by shower nozzle again.Existing plant protection sprays mechanical shower nozzle used does not have drip-proof function, sealing in the connection sealing of such as shower nozzle and jet pipe and shower nozzle is bad, after liquid pump quits work, liquid remaining in jet pipe road can ooze successively from nozzle or shower nozzle and jet pipe joint, until dead space capacity drips off liquid could be stopped to leak in pipeline.This not only causes liquid waste, and increase drug cost, also still can there is weeping when spraying machine fulfils assignment and sails out of operating area, the liquid that leaks can cause environmental pollution, even jeopardizes the life security of people or livestock and poultry or causes any property loss.Import anti-drip shower nozzle price is high, mostly is plastic material, easily aging, and in spray frame course of action, damage probability large, change frequent, use cost is high.Its screen pack appearance number is high, and fine impurity all may cause blocking, requires high to water or liquid containing solid impurity rate, and frequent clean or replacing filter screen add user's workload and use cost.
Summary of the invention: the purpose of this utility model designs a kind of drip-proof shower nozzle of spraying machine, this shower nozzle blocks liquid immediately and leaks after stopping spray medicine, does not have water clock.The pollution of medicine company to environment can not be produced.The purpose of this utility model is achieved in that the drip-proof shower nozzle of spraying machine, comprises by nozzle body, nozzle and nozzle cap.The connection pedestal of nozzle body is equipped with the seal receptacle be communicated with jet pipe.At the inner chamber of nozzle body, on the circular hole that the sealing vertex of a cone be connected with Compress Spring is communicated with jet pipe at seal receptacle.The Compress Spring other end connects with filter screen, connects nozzle below filter screen.Nozzle cap is threaded with nozzle body, and the center hole of nozzle cap end coordinates with nozzle, and nozzle, filter screen and Compress Spring are positioned at nozzle body inner chamber.
The profile of the seal receptacle that the connection pedestal of nozzle body is installed is closed with the recesses being connected pedestal.The face of cylinder connected with jet pipe tube wall is arranged at its top, the little pipe A that face of cylinder central authorities have to protrude, and little pipe A inserts in the fluid hole of jet pipe.The another side of the seal receptacle relative with the face of cylinder has a protruding little pipe B, and little pipe B enters the inner chamber of nozzle body through connecting pedestal.
On the face of cylinder that seal receptacle connects with jet pipe tube wall, outside little pipe A, be with a closure gasket groove.The face at sealing annular groove kernel of section trajectory place is parallel with the face of cylinder.
The center hole of nozzle cap end has a convex annular stupefied, the convex stupefied upper planar annular near nozzle body inner chamber and the convex stupefied face of cylinder can be located different nozzles.
Described inserts within the spiral of spring with the filter screen of spring interface, and filter screen has an annular seating be against spring end, the external diameter of this annular seating equals the path of nozzle body external spiral.
Described filter screen connects with nozzle, refers to that the annular seating of filter screen is connected with the ring surface of nozzle bottom by sealing ring.
The main body of the drip-proof shower nozzle of spraying machine is made up of stainless steel or metal chrome-plated material, and intensity is good, non-corrosive, life-span are long, and there is the O-ring seal coincide with faying face shape the part connecting part in medicinal liquid cavity, ensures sealing effectiveness.Adopt spring top means of press seals cone to close medicine liquid channel, stop in spraying, close capacity of sprinkler completely when liquid pressure is less than atomisation pressure, stop liquid water clock.This drip-proof shower nozzle compact, can be arranged on the jet pipe of various spray position and spray direction, easy to use, flexible, highly versatile.
Accompanying drawing illustrates: Fig. 1 is the structural representation of the drip-proof shower nozzle of spraying machine.Fig. 2 is the structural representation of the seal receptacle of drip-proof shower nozzle.
Detailed description of the invention: be further described below in conjunction with width figure.
As shown in drawings, the drip-proof shower nozzle of spraying machine, comprises nozzle body, nozzle and nozzle cap.Drip-proof shower nozzle is arranged on jet pipe 2 by the connection pedestal 3 of gland 1 and nozzle body.The connection pedestal 3 of nozzle body 5 is equipped with the seal receptacle 4 be communicated with jet pipe.Seal receptacle is contained in the depressed area connecting pedestal, and profile is closed with the recesses being connected pedestal.The face of cylinder 16 matched with the tube wall of jet pipe 2 is arranged at its top, and there are a protruding little pipe A18 in face of cylinder central authorities, and this little pipe A inserts in the fluid hole of jet pipe, becomes the entrance that liquid enters shower nozzle.The outer of little pipe A is with a closure gasket groove 19, and the face at sealing annular groove kernel of section trajectory place is parallel with the face of cylinder (16), and sealing ring 13 and jet pipe wall are fitted tightly.The another side of the seal receptacle relative with the face of cylinder has a protruding little pipe B17, and little pipe B enters the inner chamber of nozzle body through connecting pedestal.Sealing ring 12 is with outside little pipe B.
At the inner chamber of nozzle body, the sealing be connected with Compress Spring 10 is bored 11 and is withstood on the circular hole of little pipe B of seal receptacle.When jet pipe inner liquid medicine pressure is greater than spring pressure, sealing cone is opened, and liquid enters nozzle cavity from jet pipe, and nozzle starts to spray medicine.The spring other end connects with filter screen 9, and filter screen inserts within the spiral of spring, and filter screen has an annular seating 15 be against spring end, the external diameter of this annular seating equals the path of nozzle body external spiral.The annular seating of filter screen is connected with the location anchor ring bottom nozzle 8 by sealing ring 7.The center hole of nozzle cap end coordinates with nozzle 8, and nozzle, filter screen and Compress Spring are positioned at nozzle body inner chamber.The hole wall of the center hole of nozzle cap 6 end has a convex annular stupefied, the convex stupefied upper planar annular (14) near nozzle body inner chamber and the convex stupefied face of cylinder can be located different nozzles.Change nozzle change Sprayable very convenient.
