Abstract
The utility model belongs to the class of farm field irrigation equipment, and the utility model is put forward in order to overcome the technical problem of the existing drip irrigation emitter. The utility model is composed of a water delivery pipe and a nested drip irrigation head, the inner edge surface of the drip irrigation head is tightly matched with the surface of a water pipe, end faces which are butted with each other are also tightly cooperated and are connected by a hook. A return-shaped labyrinth shallow slot is arranged on the inner edge surface, a plurality of water outflow pinholes which are arranged on the butted end surface is communicated with a labyrinth slot of an inner part, and a water outflow slit is carved on the water delivery pipe. Water flows out through the labyrinth slot and a water outflow hole. The drip irrigation head has the action of flow limit to the water and causes the water outflow of each drip irrigation head to be coincident. The utility model is characterized in good water saving function, good operation, low cost and long service life.
Description
The utility model belongs to the field irrigation equipment class.It is specifically related to a kind of novel slight irrigation, the structure of drip irrigation equipment.
At present, the shortage of water resource has become serious world's problem, and in order to improve the availability of pouring water effectively and to improve the effect of irrigating, the irrigation installation of development high-efficiency water-saving is one of key issue of agricultural development.The irrigator that in prior art, has droplet to irrigate, it can be divided into two kinds of internally-inlaid and external mounting types, the internally-inlaid irrigator is that the long runner plastics of labyrinth type drip head is set within the tube wall, current through labyrinth path decompression current limliting after the circular hole outflow on the pipe; The external mounting type irrigator will have the labyrinth type annular channel or inside studs with the outside that the plain plastics drip head that flows of rubber diaphragm is installed in tube wall, by linking in pass runner and the pipe.In order to make work effect equalization stable, the flow of each delivery port in the certain-length scope is identical, and the delivery port aperture on the existing drip irrigation pipe and mostly is circular port generally between 0.3~1.2mm.This delivery port is very easily stopped up by the microbial adhesion in the dirt in the water, graininess impurity and the water, and this kind phenomenon is difficult to control, also is difficult to cleaning treatment after the appearance, has influenced the normal and stable operation state.
The purpose of this utility model is that------slit irrigator, it has strong, the good operation of water-saving function, low, the good maintenance of cost, nonclogging advantage in order to overcome easy obstruction and the special proposition of the difficult technical problem of safeguarding this programme that existing drip irrigation equipment exists.
By as above design, the slit irrigator that this programme provided includes water-supply-pipe, it is characterized in that suit one drip head at the water outlet slit place of water pipe, have the labyrinth type shallow slot on the inner edge surface of its drip head, connect with hook at the faying face place, a plurality of ostium excurrenses with labyrinth shallow slot UNICOM are arranged on the end face faying face, and the inner edge surface of drip head tightly cooperates with the outer edge surface of water pipe, also is tight cooperation between the end face faying face of hook.
In this programme, the maze trough in the drip head is back-shaped, also can be profile of tooth.The slit of its water-supply-pipe can be an in-line, also can be arc, zigzag or X-shape.
Adopt this programme can embody following superiority, 1. this slit irrigator is made up of water-supply-pipe and the drip head that cuts suit outside the slit place of system on tube wall, water in the pipe flows out from slit under pressure, enter maze trough, from the ostium excurrens of drip head end face faying face, flow out, according to the different requirements of flow, can prepare structure with different maze troughs, maze trough plays the effect of current limliting to water, makes working stability, the water yield unanimity of each drip head; 2. because slit can open different bores at opening part, be difficult for being stopped up, both made the drip head of opening suit when clogging occurring also get rid of cleaning easily by particle and microorganism; 3. because the slit on this water pipe is in closed form under off position, can avoid the crop hair root to have the hydrotropism to grow effectively and stop up the phenomenon of irrigator, it is underground that thereby whole equipment of pouring water can be embedded in, can reduce the volatilization loss of water, it is caused aging by solar radiation for a long time to reduce rubber tube, thereby has improved the working life of drip irrigation equipment; 4. it has tangible water-saving function, simple in structure, low cost of manufacture, characteristic of reasonable structure, is suitable for industrialized mass production and promotes the use of.
Fig. 1, Fig. 2 are the structural representations of droplet drip head edge core that has the internally-inlaid of maze trough in the prior art.
Fig. 3, Fig. 4 are the structural representations that the external mounting type drip head is inlayed part.
Fig. 5 is the outside drawing of this programme slit irrigator.
Fig. 6, Fig. 7, Fig. 8, Fig. 9 are the difform schematic diagrames of slot on the water-supply-pipe.
Figure 10, Figure 11 are the structure charts of drip head, and Figure 11 is the end view of Figure 10.
Figure 12 is the expanded view of Figure 11 inner edge surface, shows the distribution situation of maze trough.
Figure 13 is the user mode schematic diagram of this programme.
The embodiment of existing accompanying drawings this programme.This slit irrigator is made up of water-supply-pipe 1 and drip head 2, requirement by irrigation quantity, on tube wall, be carved with the slit of water outlet, suit drip head at the slit place, the inner edge surface of drip head is tight cooperating with the outer wall of water-supply-pipe, the end face faying face of its joint also becomes tight cooperation, the time place of connecing connect with hook, back-shaped labyrinth type shallow slot is arranged on the inner edge surface of drip head, on the end faying face, there is the aperture of a plurality of water outlets to communicate with maze trough, the quantity of this ostium excurrens is 3~4, and the shape of the water outlet slit on the water-supply-pipe can be an in-line, also can be zigzag, arc or X-shape.The maze trough of drip head inside can be back-shaped, also can be profile of tooth.Water-supply-pipe of this programme and drip head all will adopt good springiness and ageing-resistant elastomeric material, adopt the mode of suit between the two, characteristics easy for installation are arranged, the effect that inner maze trough has current limliting, can make each drip head water yield unanimity, it can be embedded in underground use, can improve the availability and the irrigation effect of pouring water better, slit can open the delivery port of different bores when opening, be difficult for being stopped up by particle impurity in the water and microorganism, the slit of water outlet becomes closed condition at ordinary times, so it can also overcome the obstruction that biological hydrotropism grows and forms, also is easy to if appearance is opened the drip head cleaning treatment when stopping up.It is rational in infrastructure in addition, is suitable for the characteristics of industrialized mass production, is convenient to promote the use of.
