Technical field
The utility model belongs to agricultural irrigation technology, particularly relates to a kind of Side-slit drip irrigation belt.
Background technology
Tradition Side-slit drip irrigation belt runner is designed to " zigzag " or " right-angled trapezium " structure more, after tiny gravel enters runner with water when the leading portion of labyrinth flow-path due to flow rate of water flow and pressure larger silting phenomenon is less likely to occur, and the middle and later periods due to labyrinth flow-path decompression energy dissipating effect under flow rate of water flow and pressure less, easily form silting in the corner of runner, cause the phenomenon that cannot normally drip in irrigate band or the amount of dripping is not up to standard; In addition, be limited by the limitation of production equipment and briquetting roller, irrigate band manufacture deviation is higher, affects irrigation system uniformity of irrigation water appilcation.
Therefore, based on the problems referred to above, this application provides the irrigate band that a kind of runner turning is arc-shaped, larger dynamics of washing away and eddy flow effect is not only defined at the circular arc place of this irrigate band, and the flowing pressure excessively that can effectively consume in pipeline, avoid the phenomenon of tiny gravel silting in runner.
Summary of the invention
The purpose of this utility model is to provide a kind of Side-slit drip irrigation belt, solves existing Side-slit drip irrigation belt easily forms silting phenomenon problem in the corner of runner.
In order to solve the problem, this application provides a kind of Side-slit drip irrigation belt, comprise drip irrigation belt body (1), and the irrigate band inner chamber (2) to be made up of drip irrigation belt body (1), the at least side of drip irrigation belt body (1) is provided with at least one laminar flow road (3), described runner (3) is provided with flow channel entry point (31) and runner exit (32), and described flow channel entry point (31) is arranged in described irrigate band inner chamber (2); Described runner (3) is in labyrinth type, and described runner (3) comprises following current road (33) and road, turning (34), and the corner in road, described turning (34) is arc-shaped.
As the preferred version of the application, the arc surface of road, described turning (34) both sides comprises arc surface A and arc surface B, and described arc surface A and arc surface B is oppositely arranged and/or arranges on the contrary.
As the preferred version of the application, described following current road (33) caliber is less than the caliber of road, turning (34).
As the preferred version of the application, described runner (3) is in " Ω " shape, and namely following current road (33) and road, turning (34) form " Ω " shape.
As the preferred version of the application, described runner (3) comprises the one in concavo-convex, trapezoidal shape, curve-like.
Beneficial effect
The utility model provides a kind of Side-slit drip irrigation belt, this irrigate band comprises drip irrigation belt body, and the irrigate band inner chamber be made up of drip irrigation belt body 1, and at least side of drip irrigation belt body is provided with at least one laminar flow road, runner is provided with flow channel entry point and runner exit, flow channel entry point and irrigate band inner space; Runner is labyrinth type, runner comprises following current road and road, turning, in order to avoid the phenomenon of tiny gravel silting in runner, be arc-shaped by the corner in road, turning, larger dynamics of washing away and eddy flow effect is not only defined at this arc-shaped place, and the effective flowing pressure excessively consumed in pipeline, therefore, adopt the Side-slit drip irrigation belt in the application, solve existing Side-slit drip irrigation belt easily forms silting phenomenon problem in the corner of runner.
