Abstract

The utility model provides an inlaid sheet type irrigation emitter. The inlaid sheet type irrigation emitter comprises a water inlet window, a water outlet window, an energy dissipating flow passage, a closed ring and an identification edge, wherein the closed ring is arranged in the center of the water outlet window, the height of the closed ring is 0.1-0.3mm smaller than the depth of the water outlet window, and the identification edge is a convex structure and is arranged at the back of the irrigation emitter. The inlaid sheet type irrigation emitter has the following beneficial effects: on one hand, since the water outlet window of the inlaid sheet type irrigation emitter is provided with a closed ring structure, after water irrigation is stopped, smaller passing radius can be used for preventing mud, sand and the like from entering the energy dissipating flow passage; on the other hand, since the convex identification edge is arranged at the back, the volumetric thickness of the irrigation emitter and the weight of a single irrigation emitter are effectively reduced, the irrigation emitter which is easy to identify, attach and deform is realized, the defect that a drip irrigation tape is easy to break due to great thickness and deformation difficulty is effectively reduced.

Description

Inserted-blade type irrigator in a kind of

Technical field

The utility model belongs to the novel agricultural water-saving irrigation equipment technical field that relates to, and especially relates to a kind of interior inserted-blade type irrigator.

Background technology

Along with the upgrading of China's agricultural irrigation, a large amount of farmlands adopt slight irrigation and pipe-irrigation system, this wherein drip irrigation often used by people as the canonical system of slight irrigation.

Irrigator is the core component in drip irrigation system, is the significant element that realizes irrigation technique, and its effect is by the energy-dissipating structure in irrigator, reduces in pipe racks and has the kinetic energy of pressure flow, stablizes water yield and drips the object that infiltrating irrigation is irrigate thereby reach.The irrigator of domestic current application mainly contains following several types: interior inserted-blade type irrigator, single-blade labyrinth type irrigator, column type irrigator, pressure-compensated irrigator, pipe above formula irrigator etc., wherein interior inserted-blade type irrigator apply at home more, its primary structure by water outlet window, energy dissipating runner, enter water window, identification mechanism etc. and form.

In the prior art, owing to being subject to the restriction of identification mechanism, interior inserted-blade type irrigator ulking thickness is relatively large, higher to its use and cost impact, also can propose high requirement to the material of supporting dropper.Be designed with simple cuboid tapping mechanism at water outlet window in addition, easily run in actual applications by the problem of crop root or silt obstruction.

Summary of the invention

Problem to be solved in the utility model be to provide a kind of in inserted-blade type irrigator, especially provide that a kind of identification mechanism is simple and reliable, ulking thickness is less, possess the interior inserted-blade type irrigator of stronger anti-blockage capability.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: inserted-blade type irrigator in a kind of, comprise irrigator body, described irrigator body comprises into water window, water outlet window, energy dissipating runner, it is characterized in that: described irrigator body also comprises closed-loop and identification rib, described closed-loop is arranged on described water outlet window central authorities, and described identification rib is protruding isosceles trapezoidal structure, through the irrigator body back side.

Further, the high little 0.1-0.3mm of the degree of depth that compares described water outlet window of the ring of described closed-loop, after irrigator stops pouring water, can utilize the less radius that passes through, and stops that silt etc. enters energy dissipating runner, increases the service life.

The utility model compared with prior art has the following advantages:

1, the utility model water outlet curtain heading tape has enclosed ring, after irrigator stops pouring water, can utilize the less radius that passes through, and stops that silt etc. enters energy dissipating runner, increases the service life.

2, be different from identification slot of the prior art, in the utility model, be provided with protruding identification rib, effectively reduce the ulking thickness of irrigator, reduce the weight of single irrigator, realized the irrigator of more easy to identify, easy laminating distortion, effectively reduce thickness greatly, the not yielding irrigate band the causing defect of easily pressing against brokenly.

Brief description of the drawings

Fig. 1 is planar structure schematic diagram of the present utility model.

Fig. 2 is perspective view of the present utility model.

Fig. 3 is vertical view of the present utility model.

Fig. 4 is left side view of the present utility model.

Figure comprises: irrigator body 1, water inlet window 2, water outlet window 3, energy dissipating runner 4, closed-loop 5, identification rib 6.

Embodiment

As depicted in figs. 1 and 2, be respectively the utility model plane and perspective view, figure comprises irrigator body 1, water inlet window 2, water outlet window 3, energy dissipating runner 4 and closed-loop 5.Described closed-loop 5 is arranged on the central authorities of described water outlet window 3, the high little 0.2mm of the degree of depth that compares described water outlet window 3 of ring of closed-loop 5 described in this example, it is closed-loop 5 has 0.2mm distance apart from the top of water outlet window 3, namely the gap between closed-loop 5 and drip irrigation tube wall only has 0.2mm, much smaller than the opening diameter 1mm in irrigator water outlet window 3, thereby reach the dirty ability of blocking of higher size.

As shown in Figure 3 and Figure 4, be respectively vertical view of the present utility model and left side view, figure comprises irrigator body 1 and identification rib 6, and described identification rib 6 is bulge-structure, is arranged on the back of described irrigator body 1.

The course of work of this example is:

Current enter from irrigator water inlet window 2, after the grid in water inlet window 2 filters, enter energy dissipating runner 4, current are after energy dissipating runner 4, it is stable that water yield reaches, enter water outlet window 3 along the gap between closed-loop 5 and drip irrigation tube wall, drip infiltrating irrigation and irrigate, after irrigator stops pouring water, because water outlet curtain heading tape has enclosed ring, can utilize the less radius that passes through, stop that silt etc. enters energy dissipating runner, extends the service life of described irrigator.

The operation principle of the identification rib in the utility model is: irrigator identification rib is convex, identification slot on choosing dish is spill, both utilize morpheme dimensional fits principle, identification rib is under centrifugal action, enter choosing dish identification slot, the correct irrigator of position enters identification slot, thereby reaches selection object, if convex and spill are not mated because of placement location, irrigator can not be selected.This novel identification rib design effectively reduces the ulking thickness of irrigator, its cost is declined, and reduce the requirement of later stage coiling irrigate band, has promoted quality assurance.

Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
