Description
Technical field
This utility model relates to agricultural equipment field, particularly relates to a kind of automatic for prevent liquid manure drip irrigation system from blocking
Detection device.
Background technology
Liquid manure drip irrigation is according to crop water requirement, by low pressure pipeline system and the douche installed on the capillary,
Nutrient water and crop needed uniformly and lentamente instills the irrigation method in the soil of crop root zone.Drip irrigation does not destroy soil
Structure, soil internal water, fertilizer, air and heat often keep the good condition being suitable for plant growth, and evaporation loss is little, does not produces ground
Face diameter stream, almost without deep percolation, is a kind of irrigation method saved water and energy.Drip irrigation to be mainly characterized by water consumption little, fill
Hydrophone flow per hour is 2-12 liter, and therefore, duration of once pouring water is longer, and the cycle poured water is short, can accomplish that little water is diligent
Fill；The operating pressure needed is low, it is possible to accurately Controlled irrigation amount, can reduce invalid Evaporation among plants, not result in water
Waste；Drip irrigation can also carry out automated management, saves human cost.Therefore, drip irrigation is that current field of agricultural irrigation is the most energy-conservation
Irrigation method, especially for the area that drought and water shortage and manpower are deficient, its advantage becomes apparent from.
But, drip irrigation system is less due to the water dropper bore of itself, irrigate liquid manure used contains impurity, silt with
And microorganism all can make emitter clogging.Although irrigation system itself has purification filtering function, but due to screen
Caliber size, can only filter out a certain size impurity, and the impurity of reduced size is not filtered, thus, long-term
In work process, the impurity of these reduced sizes can constantly accumulate and be gathered at water dropper, thus causes the blocking of water dropper.
At present, for emitter clogging problem, scientific research personnel has been proposed for more solution.These achievements in research master
If blocking angularly from emitter structure, fertilizer and antibiont, it is proposed that multiple water dropper clogging-preventing measures: Chinese patent

The emphasis that solves of state's patent ZL200510104225.2 is then to prepare a kind of nutritional solution existed without blocking material and solid fertilizer
Material, solves the problem that fertilizer causes drip irrigation system to block；Chinese patent ZL 201110217752.X discloses a kind of drip irrigation
Systemic antibiotic thing blocking device, containing an ozone generating-device in this device, starts ozonator when drip irrigation system is opened,
Ozone and irrigation water are mixed to form " Ozone Water " of uniform gas-liquid distribution and enter drip irrigation system, kill the microorganism in runner, with
Time, in underground drip irrigation system, due to the existence of pressure differential, crop root also can be suppressed raw to drip emitter outlet direction
Long, reach the purpose of drip irrigation system antibiont blocking.Although the advantage that these schemes are in respective design object is the brightest
Aobvious, but there is also common deficiency, it is i.e. due in actual drip irrigation operation, the environment residing for water dropper, source quality, mistake
The filter diversity such as effect, fertilizer formula is the biggest, causes these schemes can only reduce the probability of emitter clogging or extend water dropper
The nonclogging time, emitter clogging can not be avoided completely, can not be when clogging occurs and alarm.
