Abstract
The invention discloses a plugging-resistant dripper. The plugging-resistant dripper comprises a dripper body, wherein a water inlet is formed in one end of the dripper body, a water outlet is formed in the other end of the dripper body, a flow channel is formed between the water inlet and the water outlet, the dripper body is rectangular, and the cross section of the flow channel is rectangular; a plurality of cylindrical members with the same structure are arranged in the flow channel, the upper end of each cylindrical member is connected with the top surface of the flow channel, and the lower end of each cylindrical member is connected with the bottom surface of the flow channel; the cylindrical members adjacent to the wall of the flow channel are arranged in the half-cylindrical shapes, the half-cylindrical members adopt the structure which is a half of that of the cylindrical members in the flow channel, the specification design of the half-cylindrical members is the same as that of the cylindrical members, and the half-cylindrical members are fixedly connected with the wall of the flow channel; and the cylindrical members are in array arrangement, the cylindrical members in the two adjacent rows are arranged in a staggered manner, and the spacing between two adjacent cylinders in the width direction of the flow channel is smaller than the spacing between two adjacent cylinders in the length direction of the flow channel. The dripper is high in plugging resistance, reasonable in structure and stable in properties under low-pressure conditions.
Description
Technical field
The invention belongs to agricultural water-saving irrigation equipment technical field, relate to a kind of anti-blocking emitter.
Background technology
Along with the development of science and technology, the irrigation technique that this water saving efficiency of slight irrigation is higher has been widely used.Wherein
Drip irrigation has water-saving and saves the advantages such as fertile, irrigation uniformity is high, and volume increase is efficient, has obtained swift and violent development.At present, low-pressure drip irrigation and
Gravity flow drip irrigation quickly grow, pressure reduce time, design standard and the manufacturing cost of system equipment can be reduced, also have energy-conservation and
Reduce the effect of operating cost, there are the biggest potentiality saving drip irrigation system cost, be the Main way of drip irrigation technique development,
It it is the main flow of development at present.Water dropper is the core component of drip irrigation system, owing to its physical dimension is the most small, so be easy to by
Blocking, and pressure reduction considerably increases emitter clogging probability, directly influences uniformity and the service life of drip irrigation system,
And then have influence on operation and the cost of system, therefore a kind of low pressure anti-blocking emitter equipment of exploitation is significant.
Summary of the invention
It is an object of the invention to provide a kind of anti-blocking emitter, under lower pressure, its anti-blocking is strong, rational in infrastructure, property
Can be stable.
The object of the present invention is achieved like this, a kind of anti-blocking emitter, is respectively provided with water inlet, water outlet including its two ends
The water dropper body of mouth, constitutes runner between entery and delivery port, water dropper body is rectangular, and the cross section of runner is rectangular, at this runner
If being inside provided with the cylindrical member that stem structure is identical, the two ends up and down of cylindrical member all with end face and the bottom surface phase of runner
Even, the cylindrical member near flow path wall is all arranged in semi-cylindrical shape, for a half structure of runner inner cylinder component, rule
Lattice design is identical, and is connected with flow path wall；Described cylindrical member is array arrangement, and the cylindrical member between adjacent rows is handed over
Wrong setting, between adjacent two cylinders being smaller than flow channel length direction between adjacent two cylinders in width of flow path direction
Spacing.
When water dropper of the present invention uses, current are come in from water inlet, and a part of current flow through the runner between cylindrical member, because of
Cylindrical member is staggered, therefore can eliminate portion of energy, and another part current fling cylindrical member, by cylindrical structure
The stop of part, these current form reverse flow before cylindrical member, thus with forward current generation intense impact, can disappear again
Except portion of energy, adding flow turbulence, enhance the collision effect between molecule in runner, the lower molecule of this effect is not
Easily there is agglomeration, and aggregate is difficult to bond with runner, is flowed out by outlet with current, so greatly reducing blocking
Probability.The present invention uses the structure of water dropper and runner one, practical, simple in construction, is prone to processing, and advantageously reduces
Cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Fig. 1 is the main TV structure schematic diagram of the present invention；
Fig. 2 is the side-looking structural representation of Fig. 1.
Detailed description of the invention
A kind of anti-blocking emitter, as shown in Figure 1 and Figure 2, is respectively provided with water inlet 1, the water dropper of outlet 5 including its two ends
Body 4, constitutes runner between entery and delivery port, water dropper body 4 is rectangular, and the cross section of runner is rectangular, is provided with in this runner
If the cylindrical member 3 that stem structure is identical, the two ends up and down of cylindrical member 3 are all connected with end face and the bottom surface of runner, lean on
The cylindrical member of nearly flow path wall is all arranged in semi-cylindrical shape, and for a half structure of runner inner cylinder component, specification sets
Count identical, and be connected with flow path wall；Described cylindrical member 3 arranges in array, and the cylindrical member between adjacent rows interlocks
Arrange, between adjacent two cylinders being smaller than flow channel length direction between adjacent two cylinders in width of flow path direction
Spacing.Described often row cylindrical member centrage is each parallel to runner limit wall.
The cylindrical member being positioned at water dropper body water inlet and water outlet is two；Water dropper body 4 inner flow passage width
The quantity of every string full cylinder component 3 in degree direction is three, arranges between adjacent two row full cylinder components
Two full cylinder components, these two cylindrical member both sides are respectively provided with a semi-cylindrical component 2.
Spacing between spacing dimension L1 and adjacent two row cylindrical members between every adjacent two cylindrical members of string
The ratio of size L2 is 1:1.5.
