At present, in the greenhouse of China irrigation system, adopted is the caliber and the SMD irrigate band of interior edge of working head greatly greatly more, and mostly caliber is 16mm and 20mm.Though the drip irrigation system that this irrigate band is formed can reach the effect of water-saving irrigation, cost is higher.But the greenhouse by solar heat width is generally 6-8m, and when dropper band when width is arranged along the greenhouse, the dropper strip length equates that with the greenhouse width if the employing diameter is the irrigate band of 8mm, pressure divergence can meet design requirement, and the cost reduction is more than 20%.
Design to the SMD water dropper in the SMD irrigate band of edge in the greenhouse; Mainly concentrate on the analysis of its internal flow; Wherein Fluid Mechanics Computation (CFD) method reaches in the advantage aspect reduction design cost, shortening construction cycle with itself applicability, flexibility, is obtaining application comparatively widely aspect the emitter structure optimal design.The method that the utility model patent utilization CFD simulation, laser fast shaping and test combine has been developed the SMD irrigate band of edge in the low pressure that a kind of caliber is 8mm.
Summary of the invention
In order to overcome the deficiency that caliber is big, working head brings greatly that existing drip-irrigation band exists; The purpose of the utility model is, the SMD irrigate band of edge in the low pressure of tubule footpath, a kind of greenhouse is provided, and this irrigate band not only can reduce caliber; Save material, reduce cost; And reduced working head, and be convenient to control, prolong the service life of irrigate band.
In order to realize above-mentioned task, the technical scheme that the utility model adopted is:
The SMD irrigate band of edge in the low pressure of tubule footpath, a kind of greenhouse is characterized in that, in the irrigate band, studs with the paster water dropper; Described paster water dropper is formed one by plagiodont labyrinth flow-path, the gentle pool of filter screen; The plagiodont labyrinth flow-path has water inlet and delivery port, and wherein, water inlet and filter screen are communicated with; Delivery port is communicated with slow pool, and described slow pool is positioned at the length direction two ends of the labyrinth flow-path of plagiodont.
Other characteristics of the utility model are:
The length of paster water dropper is 40mm, highly is 6mm, and the degree of depth is 1.70mm.
The length of described plagiodont labyrinth flow-path (a) be 28mm, highly for 3.08mm, width is respectively 1.55mm and 1.36mm, degree of depth 0.9mm, tooth depth 1.54mm, space width 3.02mm, corner are 30 °.
The SMD irrigate band of edge in tubule footpath, the greenhouse low pressure of the utility model; Realized the advantage that little caliber and working head are low; Not only save material, reduced cost, also prolonged the service life of the dropper band of knowing clearly; Make things convenient for peasant household to utilize the water-saving irrigation product to produce, thereby reached the effect of not only economizing on water but also getting bumper crops.
