Description

单项单齿道式滴头
技术领域
本实用新型涉及一种滴头，尤其涉及一种单项单齿道式滴头。 
背景技术
滴灌技术是通过干管、支管和毛管上的滴头，在低压下向土壤经常缓慢地滴水；是直接向土壤供应已过滤的水分、肥料或其它化学剂等的一种灌溉系统。它没有喷水或沟渠流水，只让水慢慢滴出，并在重力和毛细管的作用下进入士壤。滴入作物根部附近的水，使作物主要根区的土壤经常保持最优含水状况。这是一种先进的灌溉方法。目前市场上的滴头多种多样，多数会出现灌溉均匀度不高、易赌塞、结构复杂或者高压状态使用等等问题。 
发明内容
本实用新型的目的在于设计一种单项单齿道式滴头。 
   本实用新型的技术方案：一种单项单齿道式滴头，由骨架、正面的溢流区、隔槽、齿形溢道和反面的进水窗、模孔、卡道、栅栏组成。其特征在于：单项单齿道式滴头为细长扁平形状，分为正面和反面，是一体连接注塑而成。反面骨架为一扁细长形栅栏，栅栏中线等间距分布着模孔，沿一长边分布着一细长条进水窗，长度占栅栏长边的4/5，宽度根据所需进水量而设定，不超过栅栏宽度的1/3,进水窗连通正反两面；栅栏旁镶一突出卡道。正面骨架为一四周密封，中间凹面的结构，凹面一侧由一隔条围成一方形区域为溢流区，面积占凹面的1/5，其余面积为隔槽、齿形溢道和进水窗平行分布，隔槽宽度占骨架正面宽度的1/6，进水窗宽度根据所需进水量而设定，不超过栅栏宽度的1/3。剩下的为齿形溢道的宽度。 
如上所述的齿形溢道，包括多数的齿、隔条、进水口和溢入口。其特征在于：两隔条连接这骨架边缘围成一长方条区域，与进水窗近邻的隔条右侧有一个为进水口，另一端与溢流区相连的边开一宽为0.1cm的开口为溢入口。两条隔条上均匀分布着多数齿，相对齿之间相互交错而形成齿形溢道。齿状大小根据流量而设。 
本实用新型的优越性：此单项单齿道式滴头为一次注塑成型产品，整个面的栅栏，过滤效果好，不宜堵塞滴头且结构简单，滴头流道宽，出水量大且均匀，适合需水量大且均匀供水的农作物灌溉且成本价格较低。 
附图说明
附图1为本实用新型的正面的结构示意图，
其中：1是齿形溢道、2、是隔槽3是溢流区、4是齿、5是进水窗、6是进水口、7是骨架、13是隔条、31溢入口。
附图2为本实用新型的反面的结构示意图， 
其中：5是进水窗、7是骨架、8是卡道、9是模孔、10是栅栏。
附图3为本实用新型的侧面的结构示意图， 
其中：11是反面、12是正面，8是卡道
具体实施方式
     如图所示：一种单项单齿道式滴头，由骨架7、正面的溢流区3、隔槽2、齿形溢道1和反面的进水窗5、模孔9、卡道8、栅栏10组成。其特征在于：单项单齿道式滴头为细长扁平形状，分为正面12和反面11，是一体连接注塑而成。反面11骨架7为一扁细长形栅栏10，栅栏10中线等间距分布着模孔9，沿一长边分布着一细长条进水窗5，长度占栅栏长边的4/5，宽度根据所需进水量而设定，不超过栅栏10宽度的1/3,进水窗5连通正反两面；栅栏10旁镶一突出卡道8。正面12骨架7为一四周密封，中间凹面的结构，凹面一侧由一隔条围成一方形区域为溢流区3，面积占凹面的1/5，其余面积为隔槽2、齿形溢道1和进水窗5平行分布，隔槽2宽度占骨架正面宽度的1/6，进水窗5宽度根据所需进水量而设定，不超过栅栏10宽度的1/3。剩下的为齿形溢道的宽度。
如上所述的齿形溢道1，包括多数的齿4、隔条13、进水口6和溢入口31。其特征在于：两隔条13连接这骨架7边缘围成一长方条区域，与进水窗5近邻的隔条13右侧有一个为进水口6，另一端与溢流区3相连的边开一宽为0.1cm的开口为溢入口31。两条隔条13上均匀分布着多数齿4，相对齿4之间相互交错而形成齿形溢道1。齿4状大小根据所需流量而设定。 
具体实施：水流由反面11的栅栏10过滤后经进水窗5流入正面12，由进水口6流进齿形溢道1后经由溢入口31流入溢流区3，通过溢流区流出润湿土壤，灌溉农作物。
