Abstract

The utility model discloses an irrigation drip device which comprises a labyrinth type drip head, a soft pipe engaged with the labyrinth type drip head and a water inlet pipe, wherein, at least one section detachable insertion tube is communicated with the labyrinth type drip head, an outer wall of each section of the insertion tube is averagely provided with at least one water proof plate, a floating ball is arranged in a drip insertion terminal cavity of the insertion tube end, a three-way vent arranged in the drip insertion terminal which is arranged under the floating ball is respectively communicated with water outlet holes of two sides and bottom end of the drip insertion terminal. By using the configuration of detachable insertion tube, the utility model can be adjusted according to different growing period water usage of the crop, thereby increases the application range. A floating ball and three water outlet holes are arranged at the drip insertion terminal to avoid the drip device blocked up which is caused by the solid backing-up caused by negative pressure, thereby guarantees the reliability of usage. The water proof plate arranged at the insertion tube is capable of avoiding the water back-flowing to the ground surface along the tube wall, thereby reduces the water evaporation and improves the effective utilization rate of the irrigation water.

Description

A kind of subsurface irrigation water-dropper

Technical field:

The utility model relates to irrigation installation, particularly a kind ofly is convenient to move, easy access, and equipment cost is low, the subsurface irrigation water-dropper that water-saving result is good.

Background technology:

Present removable plug-in type water dropper is to be socketed to form by an inserted link and a labyrinth emitter, is connected with water supply connector through flexible pipe again.This removable plug-in type water dropper has simple in structure, conveniently moving, cost hangs down the advantage with water-saving irrigation, but the problem of depositing has: the one, and the delivery port of the plug that drips easily stops up, the 2nd, intubation length is fixing can not be adjusted, and the 3rd, irrigate moisture content and easily flow out the face of land along inserted link.So it is unreliable to exist work in using, the scope of application is little, the shortcoming at waste water source.

Summary of the invention:

The purpose of this utility model is a kind of reliable operation of design, and is applied widely, saves the subsurface irrigation water-dropper at water source.

The technical solution of the utility model is finished as follows, it includes a labyrinth emitter and associated flexible pipe and water supply connector, it is characterized in that: have at least the dismountable intubate of a joint to be connected with labyrinth emitter, be evenly equipped with at least one eliminator plate on every joint intubate outer wall, in the plug cavity that drips that the intubate bottom connects a ball float is housed, has one three port to be communicated with the delivery port of drip plug both sides and bottom respectively in the middle of the plug that drips under the ball float.The utility model has been owing to adopted dismountable cannula structures, can regulate a degree of depth of dripping according to the needs of the different growing stages water of crop in the use, enlarged the scope of application; On the plug that drips, be provided with ball float and three silt refluence obstruction water-droppers that delivery port can prevent to cause because of negative pressure, guaranteed the reliability of using; Eliminator plate is set on intubate can prevents that moisture content from flowing out the face of land along tube wall, reduce water evaporates, reach the purpose of high-efficiency water-saving.

Description of drawings:

Fig. 1 is a structural representation of the present utility model; Fig. 2 is the structural representation of labyrinth type plug; Fig. 3 is the structural representation of intubate; Fig. 4 is the structural representation of plug of dripping.Among the figure, 1. water supply connector, 2. flexible pipe, 3. labyrinth emitter, 3-1, bell and spigot joint, 4. intubate, 4-1. bell socket, 4-2. wing eliminator plate, 4-3. bell and spigot joint, the plug that 5. drips, 5-1. delivery port, 5-2. delivery port, 5-3. delivery port, 5-4. ball float.

Embodiment:

Further describe an embodiment of the present utility model in conjunction with above accompanying drawing, the utility model is the improvement to existing plug-in type water dropper, it comprises a labyrinth emitter 3 and associated flexible pipe 2 and water supply connector 1, its improvements are that intubate 4 is manufactured dismountable structure, so that adjust according to the needs of crop growth period, simultaneously on the outer wall of every joint intubate 4, evenly be provided with the rhombus wing eliminator plate 4-2 of 1～2 diameter, be used for preventing to irrigate moisture content and flow backwards and rise to ground along tube wall and increase evaporation discharge greater than intubate.In the cavity of the plug 5 that drips of intubate 4 bottom sockets, a ball float 5-4 is housed, there is one three port to be communicated with delivery port 5-1, the 5-2 of the plug both sides of dripping and the delivery port 5-3 of bottom respectively in the middle of the plug 5 that drips under the ball float, can prevent that like this delivery port from stopping up, and guarantees the reliability of using.

Using method of the present utility model is, at first select the intubate 4-joint of appropriate length according to the needs in crop each vegetative period, also can be that two joints or three joints are by bell socket 4-1 and bell and spigot joint 4-3 socket, then with its upper end with labyrinth emitter 3 by bell and spigot joint 3-1 socket, the lower end and plug 5 sockets of dripping get final product by flexible pipe 2 and water supply connector 1 labyrinth emitter 3 at last with the water source connection.Working stability is reliable, is convenient to move.

Claims

1, a kind of subsurface irrigation water-dropper, it includes a labyrinth emitter and associated flexible pipe and water supply connector, it is characterized in that: have at least the dismountable intubate of a joint to be connected with labyrinth emitter, in the plug cavity that drips that the intubate bottom connects a ball float is housed, has one three port to be communicated with the delivery port of drip plug both sides and bottom respectively in the middle of the plug that drips under the ball float.

2, a kind of subsurface irrigation water-dropper according to claim 1 is characterized in that: be evenly equipped with at least one eliminator plate on every joint intubate outer wall.
