Abstract
The utility model relates to an inlaid patch-type dropper for a dripping irrigation tube (tape), which belongs to the technical field of agricultural water-saving irrigation equipment. The dropper mainly comprises flow windows, runners, punch frames and other structures. The runners (1), the punch frames (2) and the flow windows (3) are communicated and pasted on the inner wall of the dripping irrigation tube to form closed runner systems. The dropper with the novel structure is characterized in that the dropper is provided with the runner systems (flow windows, runners and punch frames) on both sides and positive and negative structures with symmetric centers, eliminates the positive and positive as well as front and rear difference so as to simplify an on-line dropper sorting procedure. The double-sided runner dropper is characterized by formation on both sides, positive and negative structures with symmetric centers and simple use.
Description
Technical field: the utility model relates to a kind of interior SMD drip irrigation pipe of edge (band) and uses flat water dropper, belongs to the agricultural water-saving irrigation equipment technical field.
Background technology: China is since the pilot demonstration of the drip irrigation technique eighties in 20th century, and the nineties, the drip irrigation economize technology obtained comprehensively popularizing.The drip irrigation technique early stage of development is mainly based on single-blade labyrinth type drip irrigation pipe (band), the large scale application of cotton cultivation with film mulched drip irrigation planting patterns, make that the development of drip irrigation technique and product is rapider, and introduced external more advanced drip irrigation product---internally-inlaid drip irrigation pipe (band), this product has improved the uniformity of pouring water greatly, but because this product structure complexity, the manufacturing technique requirent strictness, especially thin wall irrigation belt product, be in the new development stage that is introduced into independent research from imitated in China, at present domestic have only Gansu Da Yu to economize on water, the Qin Chuan water saving, Beijing Lv Yuan, enterprise of several family such as Xingjiang Tianye Co. produces.
Water dropper is one of critical component of underground drip irrigation system, and its effect is to make pressure water stream by the abundant energy dissipating of inner flow passage, splashes into soil with stable, uniform low discharge.The performance quality of water dropper is directly connected to the performance of pouring water of drip irrigation pipe (band), and therefore the more advanced water dropper of design is the key point that constantly promotes drip irrigation pipe (band) quality and performance.
Traditional flat water dropper has the characteristics of single face runner, asymmetric, short runner, and these 3 make traditional flat water dropper go out more problem in producing and using, as problems such as anti-sheet, reviewing, selection complex procedures.The selection operation of tradition water dropper is to utilize rotation to produce centrifugal force on the choosing dish water dropper to be thrown in the card rail that selects plate edge, constantly be transported to linear conveyor track again, unnecessary water dropper that a plurality of chip select valves will be stacked respectively with air-flow is arranged during this time, be not stuck in anti-sheet, reviewing in the card rail card rail that blows off, guarantee water dropper enter delivery track be water dropper runner forming surface up, and guarantee that the punching frame is in the right direction.In this operation key be valve go out the entraining air stream orientation, card rail track width and the intact degree of shape.Because this operation is because valve air-flow reliability is relatively poor relatively, can not blow away the anti-sheet and the reviewing that are stuck in the card rail fully, therefore need on this operation, arrange a chip select worker, on delivery track, be responsible for anti-sheet and reviewing that cleaning choosing dish can not choose, and cleaning quality influenced by personnel's working level bigger.
For these reasons, it is better to design a kind of performance, produce to use easier water dropper to improving drip irrigation pipe (band) quality, and the simplification production technology is significant.
Summary of the invention: the purpose of this utility model provides a kind of functional, features simple structure, and processing technology is easy to operate, the SMD water dropper of interior edge of use.
The utility model comprises the design of water dropper new structure.
The utility model operation principle: after water dropper enters the choosing dish, because being thrown to, centrifugal action carries on the card rail, this moment, the part water dropper was stuck on the card rail fully, but the part water dropper can not be selected into the card rail, water dropper travels forward along with the choosing dish rotates, chip select valve air-flow blow away pile up and be not selected into the water dropper of card rail after, water dropper enters linear conveyor track, under blowing, conveying valve air-flow moves to the paster core bar, water dropper process paster core bar sticks on drip irrigation pipe (band) inwall that is melted in elastomeric state when terminal, water dropper and tube wall bond together behind the cooling and shaping, form complete, the flow passage system of sealing.Scheme of the present utility model is specially: a kind of two-sided runner water dropper, to form by runner (1), the frame (2) that punches, stream window (3) primary structure, and the stream window is that two side runners are shared, the water dropper both sides all are formed with runner and punching frame, and symmetry in the middle of the relative water dropper.
The utility model is achieved in that at the water dropper tow sides and all designs runner, and the frame that will punch is placed on the center of water dropper, allow runner prolonging the water dropper edge with " returning " shape around around punching frame, the shared stream window of (see figure 3) water dropper tow sides.When chip select and paster, no matter which face of tow sides is attached to can both form complete water dropper flow passage system on the drip irrigation pipe inwall, tow sides double-faced forming designs simplification water dropper selection operation, card rail, the adjustment of chip select valve are required significantly to reduce, anti-sheet, reviewing have been eliminated, reduce the chip select workload, reduced the hand labor cost, made the selection operation more easily control, easily go.Behind the bonding forming, no matter bonding plane is A face or B face, and current all are to arrive runner through the overcurrent window at the bonding plane that is flowing in of water dropper, arrive the punching frame through runner again, after aperture flows out, different is runner is in bonding back rotation direction difference, and the flow direction is opposite.

Fig. 3, water dropper 2D structural representation (three-view diagram)
The specific embodiment:
With reference to the accompanying drawings 1,2,3, shown in structure, be the flat water dropper monomer structure of two-sided runner, comprise runner (1), punching frame (2), stream window (3).Water dropper adopts the moulding of injection moulding mode, and 1 pair of mould has a plurality of die cavities, can produce in a large number.
Water dropper forms closed flow towards internal face and drip irrigation pipe (band) tube wall after being bonded in drip irrigation pipe (band) inwall, be assembled into complete douche system.
Claims (2)
1. a two-sided runner water dropper is made of stream window (1), runner (2), frame (3) primary structure that punches, and the stream window is that two side runners are shared, and the water dropper both sides all are formed with runner and punching frame, and symmetry in the middle of the relative water dropper.
2. two-sided according to claim 1 runner water dropper is characterized in that: water dropper all has molding runners (1) and punching frame (3) two sides, offer stream window (2) in the water dropper intermediate layer, uses jointly for the both sides flow passage system, is formed with two bonding planes.
