滴灌技术被公认为是一种节能、效果好的灌溉方式,对于大多数缺水地区都在大力推广,目前,多数的滴灌都是采用在植株上面定点滴灌;由于我国南方不少地区属亚热带地区,水资源中水质含钙质较高,气候特点又造成水源中苔藓藻类生长旺盛,容易堵塞输水器,造成灌水不均匀,影响植物生长;同时,面对南方烈日的植物,不但根部需要水,叶面也需要水的滋润,而目前市面上与喷灌或滴灌配套的喷(水)头滴(水)头大都是单一功能的、都难以同时满足既能作为喷头在作物叶面喷施,又能作为滴(水)头在根部灌水施肥这两个要求。Drip irrigation technology is recognized as an energy-saving and effective irrigation method, and it is being vigorously promoted in most water-deficient areas. At present, most drip irrigation uses fixed-point drip irrigation on plants; because many areas in southern China are subtropical areas , the water quality in water resources is high in calcium, and the climate characteristics cause the vigorous growth of moss and algae in the water source, which can easily block the water delivery device, resulting in uneven irrigation and affecting plant growth; at the same time, plants facing the hot sun in the south not only need water for their roots , the leaf surface also needs water to moisten, and most of the sprinkler (water) heads and drip (water) heads on the market that are compatible with sprinkler irrigation or drip irrigation are single-function, and it is difficult to satisfy both spraying on the crop leaf surface as a sprinkler head, It can be used as a drop (water) head to irrigate and fertilize these two requirements at the root.
实用新型内容:Utility model content:
本实用新型的目的在于提供一种滴喷双效灌水器,该灌水器通过两种压力结构设计,使喷灌和滴灌可以在一个灌水器内完成,既可作为喷头在作物叶面喷施,又具有能作为滴(水)头在根部灌水施肥的功能,本实用新型还提供了如何控制该滴喷双效灌水器实现上述功能的滴喷双效灌溉系统。The purpose of this utility model is to provide a drip spray double-effect sprinkler.

It can be used as a drop (water) head to irrigate and fertilize the roots. The utility model also provides a drip-spray double-effect irrigation system how to control the drip-spray double-effect sprinkler to realize the above-mentioned functions.
解决上述技术问题的技术方案是:一种滴喷双效灌水器,包括带灌溉水进口的连接体,位于连接体上部由支撑套、转动体和转动体支架组成的喷头部分和位于连接体下部由锥接头、插杆组成的滴头部分以及用于转换灌溉水流向的阀芯及弹簧;The technical solution to solve the above-mentioned technical problems is: a drip spray double-effect irrigator, including a connecting body with irrigation water inlet, a sprinkler head part composed of a support sleeve, a rotating body and a rotating body bracket located on the upper part of the connecting body, and a nozzle part located at the lower part of the connecting body. The dripper part consisting of a cone joint, an insert rod, a valve core and a spring for changing the flow direction of irrigation water;
喷头部分的转动体支架与连接体之间为牢固的锥面压紧连接,支撑套镶嵌在转动体支架内,转动体套接在支撑套上与之小间隙配合;转动体能在支撑套和转动体支架支持下自由转动,支撑套中心有喷灌水进水通道;The rotating body bracket of the nozzle part and the connecting body are firmly connected by a conical surface. The supporting sleeve is embedded in the rotating body bracket, and the rotating body is sleeved on the supporting sleeve to match it with a small gap; It can rotate freely under the support of the body bracket, and there is a sprinkler water inlet channel in the center of the support sleeve;
内有滴灌水进水通道的锥接头通过具有内外螺纹结构的螺套连接在连接体的下方,下部设有滴灌水出水口的插杆位于锥接头下方、与锥接头之间锥面压紧牢固连接;The cone joint with the drip irrigation water inlet channel is connected under the connecting body through the screw sleeve with internal and external thread structure, and the insert rod with the drip irrigation water outlet at the bottom is located under the cone joint, and the cone surface between the cone joint and the cone joint is firmly pressed. connect;
阀芯位于连接体内部并与其小间隙配合、可灵活上下移动,阀芯圆周有两条细小的通孔作为节流楔槽,即:滴灌水进水通道,弹簧安装在螺套内孔内,一端套接在锥接头上、另一端顶住阀芯。The spool is located inside the connecting body and cooperates with its small gap, and can move up and down flexibly. There are two small through holes on the circumference of the spool as throttling wedge grooves, namely: the drip irrigation water inlet channel, and the spring is installed in the inner hole of the screw sleeve. One end is sleeved on the taper joint, and the other end withstands the valve core.
由于采用上述结构,本实用新型滴喷双效灌水器及滴喷双效灌溉系统的有益效果是:Due to the adoption of the above structure, the beneficial effects of the drip spray double-effect irrigation device and the drip spray double-effect irrigation system of the present invention are:
1、使喷灌和滴灌可以同时在一个灌水器内完成,既可作为喷头在作物叶面喷施,又具有能作为滴(水)头在根部灌水施肥的功能。1. Sprinkler irrigation and drip irrigation can be completed in one emitter at the same time. It can be used as a sprinkler to spray on the leaves of crops, and it can also be used as a drip (water) head to irrigate and fertilize the roots.
本实用新型之滴喷双效灌水器采用直插式结构,进入灌水器的灌溉水(有压力的),会被阀芯转换其流向,利用进水压力来控制阀芯滑动,使水在两个进水口之间转换(喷灌和滴灌),从而达到选择滴灌还是喷灌的目的;The drip-spray double-effect emitter of the utility model adopts a direct plug-in structure, and the irrigation water (with pressure) entering the emitter will be converted by the valve core to its flow direction, and the water inlet pressure is used to control the sliding of the valve core, so that the water flows between the two sides. Switch between two water inlets (spray irrigation and drip irrigation), so as to achieve the purpose of choosing drip irrigation or sprinkler irrigation;
当系统压力低时,使用的是滴灌模式,对高矮杆作物均可滴灌至植物根部,不同以前的滴灌从土壤表面滴水入土,真正把水送到植物吸水口,实现植物“喝水”而非灌水,减少水分蒸发,合理利用灌溉水资源。When the system pressure is low, the drip irrigation mode is used, which can drip irrigation to the roots of plants for tall and short crops. Unlike the previous drip irrigation, water drips from the soil surface into the soil, and the water is actually sent to the plant water intake, so that the plants "drink water" instead of Irrigate, reduce water evaporation, and rationally use irrigation water resources.
当系统压力高时,使用的是喷灌微喷模式,微喷时,可据植物生长高低情况,插杆可伸缩、接驳,能及时补充植物叶面水分,或喷施叶面肥和药水,非常实用有效。When the system pressure is high, the mode of sprinkling and micro-spraying is used. During micro-spraying, the inserting rod can be retracted and connected according to the height of the plant growth, which can replenish the water on the plant leaves in time, or spray foliar fertilizers and potions. Very practical and effective.
2、系统功能多样:本实用新型滴喷双效灌溉系统不仅可以作为灌溉系统,还可以根据需要,调节工作压力喷洒水雾或药物,用于调节局部小气候,防霜冻。2. The system has multiple functions: the utility model drip-spray double-effect irrigation system can not only be used as an irrigation system, but also can adjust the working pressure to spray water mist or medicine according to the needs, which is used to adjust the local microclimate and prevent frost.

1、当采用0.05-0.2MPa水压时,灌溉水通过灌溉水进口(连接体圆管形凸台的中心孔)进入灌水器时,由于压力低,差动压力小于弹簧6压紧力,无法推动阀芯5,阀芯5上段51顶部的锥面51a与该连接体阶梯孔小孔段411与连接体阶梯孔中孔段412连接处的锥面41a紧配合,封住连接体与喷头部分相连接的出口,从连接体进水口进入的灌溉水只能通过阀芯5中间段的节流楔槽521节流到锥接头8和插杆9组成的滴灌芯管滴到植物根部;此时起滴灌作用。1. When the water pressure of 0.05-0.2MPa is used, when the irrigation water enters the emitter through the irrigation water inlet (the central hole of the circular tube-shaped boss of the connecting body), due to the low pressure, the differential pressure is less than the pressing force of the spring 6, and cannot Push the
2、采用0.3-0.4MPa水压时,灌溉水通过灌溉水进口(连接体圆管形凸台的中心孔)进入灌水器时,由于压力高,差动压力大于弹簧6压紧力,压力灌溉水推动阀芯5向下运动,阀芯中间段52与阀芯小轴径段53之间的锥面52b封堵螺套7内孔而封堵滴灌出水流道,阀芯5上段51顶部的锥面51a离开连接体阶梯孔中孔段412连接处的锥面41a,并打开连接体与喷头部分相连接的出口,带有较大压力的灌溉水经过以下途径:连接体阶梯孔的中段412→连接体阶梯孔的小孔段411→支撑套中心孔31→扇形斜槽上的喷水口211→扇形斜弯槽21喷出,压力水持续冲击转动体2一边喷洒一边高速旋转,水射程可达3.5米,雾化程度也较好;此时起微喷灌作用。2. When the water pressure of 0.3-0.4MPa is used, when the irrigation water enters the emitter through the irrigation water inlet (the central hole of the circular tube-shaped boss of the connecting body), due to the high pressure, the differential pressure is greater than the pressing force of the spring 6, and the pressure irrigation The water pushes the
其技术参数为:Its technical parameters are:
额定工作压力(MPa):0.05-0.2(滴灌)/0.3-0.4(喷灌);Rated working pressure (MPa): 0.05-0.2 (drip irrigation)/0.3-0.4 (spray irrigation);
射程:3.5米(喷灌)流量(L/h):5(滴灌)/35(喷灌)。Range: 3.5 meters (spray irrigation) Flow rate (L/h): 5 (drip irrigation)/35 (spray irrigation).
