Abstract
The utility model relates to an agricultural drip irrigator with jet oscillator, wherein, a jet oscillator which is arranged on the prior drip irrigator consists of a feedback loop, an adjustable flow resistance and an output pipe; moreover, the jet oscillator is of longitudinal symmetry; accordingly, the lower part of the drip irrigator is also provided with two sets of main pipes, capillary tubes and drip holes. Due to the function of the jet oscillator, the drip irrigator can greatly reduce the pressure on a filter and drip hole blockage, thereby ensuring normal use of the drip irrigator.
Description
Technical field:
The utility model belongs to modern agricultural device technology field, is specifically related to a kind of drip irrigation appliance that has fluidic oscillator.
Background technology
The employing drip irrigation appliance is irrigated and is applied fertilizer in modern agriculture, not only can save water resource, and can save fertilizer, labor savings.At present, the general structure of this device as shown in Figure 1.It is by drainage type fertilizer applicator, filter, trunk line and have the hollow billet that drips the hole etc. and constitute.Usually, each flow that drips the hole be approximately the 3-4 liter/hour, in fact make sinuate tubule so drip a hole, to increase flow resistance, the minimizing flow.In addition, in the water source of irrigating usefulness, be mixed with impurity such as silt and microorganism inevitably, when fertilising, also be mixed with a large amount of fertiliser granulates.These cause easily and drip hole plug.For preventing to drip hole plug, very high to the filter capacity requirement of filter.So-called filter is actually and allows porous such as net that water passes through or sand separate matter, to filter impurity.But after filter used certain hour, itself also can be blocked, therefore, often needs to clean or recoil, brings very big inconvenience to use.
Summary of the invention
The purpose of this utility model is to propose a kind ofly to alleviate filter pressure, thereby uses more convenient drip irrigation appliance.
The drip irrigation appliance of the utility model design is by drainage type fertilizer applicator, filter, trunk line with have the hollow billet that drips the hole and constitute.And (promptly corresponding to the P place among Fig. 1) also is provided with a fluidic oscillator in the filter back.And its trunk line and hollow billet are also done corresponding improvement.The structure of fluidic oscillator as shown in Figure 2.It is made of backfeed loop 8, adjustable flow resistance 9, output channel 10; And be laterally zygomorphic two parts, its infall is provided with pit 11, and this pit can make tube fluid produce vortex; Adjustable flow resistance 9 is arranged at the side of backfeed loop 8, is used to regulate the size of drainage; The input channel 7 of fluidic oscillator is taken over the output channel of filter 3, and two output channels 10 of fluidic oscillator connect two trunk lines 12 in downstream respectively.Therefore, trunk line of this drip irrigation appliance and hollow billet have designed two covers respectively, as shown in Figure 3.Be that each trunk line is provided with some capillarys 13 and the corresponding hole 14 of dripping.
The operation principle of the fluidic oscillator in this drip irrigation appliance is as follows, although this element symmetry up and down, because the effect of the locking vortex of wall attachment effect and pit, water can only be from certain outflow two output channels up and down.After supposing that water flows out from last output channel, at this moment the drainage meeting automatic switchover water source in the backfeed loop flows out from following output channel, can be in alternately outflow of two output channels up and down thereby form the import water source.Adjustable flow resistance group 10 is used to regulate the drainage size, so that select suitable switching time.
This drip irrigation appliance is owing to be provided with fluidic oscillator, its advantage is as follows: (1) is not stable but interrupted because current alternately flow out at two output channels up and down by the liquid stream that drips the hole, is pulsed, this can play the effect of washing away to the sediments in the tubule, helps preventing stopping up; (2) owing to be two output channels, the flow in every hole can reduce half, needn't be too thin so drip the tubule at place, hole, can be thicker than original, and usually, this caliber can also help avoiding obstruction than original increase 10%-50%.Thus, can alleviate the pressure of filter greatly.In addition, because fluidic oscillator does not have movable member, structure is simple again, can be durable in use.Therefore, this drip irrigation appliance can be avoided the deficiency of original device, brings great convenience to use.

Embodiment
Further describe the utility model below by embodiment, but be not limited to this embodiment.Drip irrigation appliance in the fluidic oscillator upstream portion is the same with original device, can not change, and is promptly still connected to form through pipeline by water pump 1, fertilizer applicator 2, filter 3 etc.Fluidic oscillator as shown in Figure 2, the width of its backfeed loop 8 is 1 centimetre, the width of output channel 10 is 1.5 centimetres, the width of inlet pipeline 7 is 2 centimetres, the angle of two output channels 10 is 30 °, the diameter of pit 11 is 2 centimetres, and pit centres is 3 centimetres to the distance of backfeed loop porch, and the thickness of device pipeline is 2 centimetres.Flow resistance 9 adopts adjustable gate valve.The downstream part of drip irrigation appliance is arranged with two-way trunk line 12 as shown in Figure 3, and is respectively equipped with corresponding hollow billet 13 and drips a hole 14, drip hole 14 the comparable original device of pipeline drip the thick of hole.After installing, promptly get required drip irrigation appliance.
Claims (2)
1, a kind of drip irrigation appliance, by drainage fertilizer applicator, filter, trunk line with have the hollow billet that drips the hole and constitute, it is characterized in that also being provided with fluidic oscillator in the filter back, this fluidic oscillator is made of backfeed loop (8), adjustable flow resistance (9), output channel (10), and is symmetrical up and down; Its infall is provided with pit (11); Adjustable flow resistance (9) is arranged at the side of backfeed loop (8); The input channel of fluidic oscillator (7) is taken over the output channel of filter (3), and two output channels (10) connect two trunk lines (12) in downstream respectively, and trunk line (12) connects corresponding hollow billet (13) respectively and drips hole (14).
