2、中国发明专利“一种水肥一体化的微喷灌溉施肥系统(CN201410587147)”公开了灌水器固定在升降柱上，但没有具体的设计，而微喷带在实际悬挂铺设和升降过程中仍存在诸多科学和技术难题尚未解决。比如：采用常规的微喷带在悬挂、升降过程中容易发生旋转，导致喷射水流角度的改变，从而降低灌溉水分布均匀度，影响作物产量。2. The Chinese invention patent "A micro-spray irrigation and fertilization system integrating water and fertilizer (CN201410587147)" discloses that the sprinkler is fixed on the lifting column, but there is no specific design, and the micro-spray belt is still suspended during the actual suspension laying and lifting process. There are many scientific and technical problems that have not yet been resolved. For example: the use of conventional micro-spray belts is prone to rotation during the suspension and lifting process, resulting in changes in the angle of spray water flow, thereby reducing the uniformity of irrigation water distribution and affecting crop yields.

所述的支柱分布于农田的首尾两端，农田同一端的支柱沿地头呈直线排列，固定在地面上，间距为6～10米；农田两端的支柱一一对应，相对的两个支柱由一根悬挂钢丝(索)连接，悬挂钢丝(索)两端分别固定在升降滑块上；每根悬挂钢丝(索)下面可活动的设有可伸缩支撑杆；可伸缩支撑杆长度可调；所述支撑杆一端为圆弧槽，用以托举微喷带，另一端呈锥形，用以插入地下固定支撑杆；可悬挂微喷带宽边上的圆孔通过挂钩悬挂在悬挂钢丝(索)上。The pillars are distributed at both ends of the farmland, and the pillars at the same end of the farmland are arranged in a straight line along the ground and fixed on the ground with a distance of 6-10 meters; the pillars at both ends of the farmland correspond to each other, and the two opposite pillars The suspension steel wire (cable) is connected, and the two ends of the suspension steel wire (cable) are respectively fixed on the lifting slider; each suspension steel wire (cable) is movable below a telescopic support rod; the length of the telescopic support rod is adjustable; One end of the support rod is an arc groove, which is used to lift the micro-spray belt, and the other end is tapered, used to insert the underground fixed support rod; the round hole on the side of the micro-spray belt can be hung on the suspension wire (cable) through a hook .

本发明具有以下有益效果：The present invention has the following beneficial effects:
1、本发明可根据不同作物的株高和群体结构特点，通过升降系统调节微喷带的铺设高度，防止植株茎叶对喷射水流的阻挡,喷幅(微喷带向两侧喷出的水流所能达到的宽度)较宽，显著减少单位面积上的微喷带用量，同时减少了微喷带铺设和卷收的人力、物力投入。例如，在小麦、玉米生育期内，既可以升高微喷带，使其位于植株上方，喷射水流不会受到植株茎叶的阻挡；也可以在玉米生育中后期，将微喷带下落至贴近地面的位置，让水流通过植株中下部的空隙喷射到远处。1. The present invention can adjust the laying height of the micro-spray belt through the lifting system according to the plant height and group structure characteristics of different crops, so as to prevent the stem and leaves of the plant from blocking the jet water flow, and the spray width (the water flow sprayed from the micro-spray belt to both sides) The width that can be achieved) is wide, which significantly reduces the amount of micro-spray tape per unit area, and at the same time reduces the manpower and material input of micro-spray tape laying and rolling. For example, during the growth period of wheat and corn, the micro-spray belt can be raised so that it is located above the plant, and the spray water flow will not be blocked by the stems and leaves of the plant; The location of the ground allows water to be sprayed to a distance through the gap in the middle and lower part of the plant.
2、本发明所设计的微喷带在田间安装时采用单边悬挂的方式，不会在悬挂和升降过程中发生微喷带扭转的情况，有效解决了目前采用单根钢丝和若干套扣悬挂的常规微喷带易发生偏转，导致喷射水流偏斜、灌溉不均匀的问题。2. The micro-spray belt designed by the present invention adopts a unilateral suspension method when it is installed in the field, and the situation that the micro-spray belt does not twist during the suspension and lifting process effectively solves the current problem of using a single steel wire and several sets of buckles for suspension. The conventional micro-spray belt is prone to deflection, resulting in deflection of spray water flow and uneven irrigation.
3、本发明微喷带的铺设间距大、设施占地空间小，可与深松、少耕、免耕技术相适应，不影响土地耕作和作物换季播种等机械作业，一次安装，可长期固定使用，相比传统的肥水管理方式，显著减少劳动力投入，提高了工作效率。3. The micro-spray belt of the present invention has a large laying distance and a small space occupied by the facilities, which can be adapted to subsoiling, less-tillage, and no-tillage technologies, and does not affect mechanical operations such as land cultivation and crop planting in different seasons. Once installed, it can be fixed for a long time Compared with traditional fertilizer and water management methods, it significantly reduces labor input and improves work efficiency.
