Description
Technical field
The present invention belongs to agricultural equipment technical field, relates to a kind of irrigator.
Background technology
Drip irrigation utilizes plastic conduit that water is delivered to crop root by the aperture on hollow billet or water dropper to carry out localized irrigation.It is the most effective a kind of Water Saving Irrigation Mode of current drought and water-scarce area, and the availability of water can reach 95%.Drip irrigation is comparatively sprayed and is had higher water-saving and yield-increasing effect, in conjunction with fertilising, can improve fertilizer efficiency more than one times simultaneously.Be applicable to fruit tree, vegetables, economic crops and green house to irrigate, also can be used for field crop irrigation in the place of drought and water shortage.
But irrigator in the market, is very easy to fouling and blocking.The reason of blocking is diversified, roughly can be divided into three major types, physical clogging, electroless Ni-P-C-O plating and toxicity bioassay.Silt in water can cause physical clogging, water quality when this just requires drip irrigation, generally all should through filtering, and the reasonable Arrangement of irrigator, just can reduce the generation of physical sedimentation.But more be but generate by inorganic substances generation chemical reaction the toxicity bioassay that the electroless Ni-P-C-O plating of precipitation and organic substance or microorganism cause.The blocking of irrigator can make whole irrigation system normally work.
Summary of the invention
In order to solve the problem of chemistry and the biological irrigator obstruction caused, the invention provides a kind of without blocking irrigator, this device can effectively process chemical precipitation and biological organic matter, prevents irrigator from blocking, increases irrigation efficiency.
The object of the invention is to be achieved through the following technical solutions.
Without blocking irrigator, comprise dropper joint, catchment lumen, offer water inlet and be communicated with the lumen that catchments in dropper joint, lumen lower side of catchmenting offers water dropper hole; Catchment setting pressure air cavity in lumen, and pressure air cavity is connected with the second bronchi with the first bronchi by pressure wireway; Install piston push rod bottom first bronchi, piston push rod bottom is connected with water dropper lid; Arrange back-moving spring between piston push rod and water dropper lid, piston push rod runs through in back-moving spring; The water dropper end of hydrochloric acid water dropper is connected with the lumen that catchments, and the other end is connected with the second bronchi.
As preferred further, described water dropper lid shelters from a water dropper hole part, and water dropper hole is 1 ~ 4.
As further preferably, described hydrochloric acid water dropper is provided with acid inlet.
As preferred further, described hydrochloric acid water dropper is fixed on bottom the lumen that catchments by bracket.
Operation principle: inserted in water conveyance conduit by the dropper joint without blocking irrigator of the present invention, water then enters from water inlet the lumen that catchments, more slowly oozes from water dropper hole.If water dropper hole plug, water level rises.Squeeze pressure air cavity after water level rises, the air pressure in pressure air cavity is made to become large, pressure becomes large rear portion pressure and enters the first bronchi promotion piston push rod extruding promotion water dropper lid by pressure wireway, the contact surface in water dropper lid and water dropper hole is diminished, increases discharge and wash away blocking dropping head hole; A part of pressure enters extruding hydrochloric acid water dropper from the second bronchi in addition, and hydrochloric acid water dropper is squeezed and can enters and catchment lumen from oozing hydrochloric acid; Hydrochloric acid is by water dropper lid and the gap in water dropper hole and the calcium carbonate of the lumen dissolution precipitation that catchments and so on sediment.By bilayer except block system, after the cleaning of water dropper hole, water level decreasing, the pressure of pressure air cavity reduces, on the one hand when pressure is less than the reset force of back-moving spring time, water dropper lid will reset thus control the flow in water dropper hole, on the other hand, because the pressure hydrochloric acid water dropper that diminishes would not be squeezed, thus hydrochloric acid also can not drip, the flow of water dropper will recover stable, is controlled the discharge of water dropper by such circulation dynamically.
beneficial effect of the present invention:of the present invention simple without blocking irrigator structure, utilize the pressure size of pressure air cavity to carry out the effect of control piston push rod, thus the size in regulation and control space, water dropper hole, avoid emitter clogging.Simultaneously again by the effect of a small amount of hydrochloric acid, calcium carbonate and so on sediment is dissolved, reach double-deck anti-blocking effect, effectively ensure that the unimpeded of the water dropper hole of irrigator of the present invention, improve the efficiency and stability of irrigating.
